The claimed invention relate to a multi-aperture vacuum tool as defined in claim <NUM>.

Illustrative embodiments of the claimed invention are described in detail below with reference to the attached drawing figures, which are incorporated by reference herein and wherein:.

The subject matter of embodiments of the claimed invention is described with specificity herein to meet statutory requirement.

<FIG> depicts a top-down view of an exemplary vacuum tool <NUM> having a first vacuum portion (e.g., distributed vacuum tool) and a second vacuum portion <NUM> (e.g., refined vacuum tool), in accordance with embodiments of the claimed invention. In various aspects, the vacuum tool <NUM> may also be referred to as a vacuum-powered part holder. For example, the vacuum tool <NUM> may be useable in an automated (or partially automated) manufacturing process for the movement, positioning, and/or maintaining of one or more parts. The parts manipulated by the vacuum tool <NUM> may be rigid, malleable, or any combination of characteristics (e.g., porous, non-porous). In an exemplary aspect, the vacuum tool <NUM> is functional for picking and placing a part constructed, at least in part, of leather, polymers (e.g., PU, TPU), textiles, rubber, foam, mesh, and/or the like.

The material to be manipulated by a vacuum tool may be of any type. For example, it is contemplated that a vacuum tool described herein is adapted for manipulating (e.g., picking and placing) flat, thin, and/or lightweight parts of various shapes, materials, and other physical characteristics (e.g. pattern cut textiles, non-woven materials, mesh, plastic sheeting material, foams, rubber). Therefore, unlike industrial-scaled vacuum tools functional for manipulating a heavy, rigid, or non-porous material, the vacuum tools provided herein are able to effectively manipulate a variety of materials (e.g., light, porous, flexible).

The vacuum tool <NUM> is comprised of a vacuum generator <NUM>. The vacuum generator generates a vacuum force (e.g., low pressure gradient relative to ambient conditions). For example, the vacuum generator may utilize traditional vacuum pumps operated by a motor (or engine). The vacuum generator may also utilize a venturi pump to generate a vacuum. Further yet, it is contemplated that an air amplifier, which is also referred to as a coandǎ effect pump, is also utilized to generate a vacuum force. Both the venturiǎ pump and the coandǎ effect pump operate on varied principles of converting a pressurized gas into a vacuum force effective for maintaining a suction action. While the following disclosure will focus on the venturi pump and/or the coandǎ effect pump, it is contemplated that the vacuum generator may also be a mechanical vacuum that is either local or remote (coupled by way of tubing, piping, and the like) to the vacuum tool <NUM>.

The vacuum tool <NUM> of <FIG> is also comprised of a vacuum distributor <NUM>. The vacuum distributor <NUM> distributes a vacuum force generated by the vacuum generator <NUM> across a defined surface area. For example, a material to be manipulated by the vacuum tool <NUM> may be a flexible material of several square inches in surface area (e.g., a leather portion for a shoe upper). As a result of the material being at least semi-flexible, the vacuum force used to pick up the part may be advantageously dispersed across a substantial area of the part. For example, rather than focusing a suction effect on a limited surface area of a flexible part, which may result in bending or creasing of the part once support underneath of the part is removed (e.g., when the part is lifted), dispersing the suction effect across a greater area may inhibit an undesired bending or creasing of the part. Further, it is contemplated that a concentrated vacuum (non-dispersed vacuum force) may damage a part once a sufficient vacuum is applied. Therefore, in an aspect of the claimed invention, the vacuum force generated by the vacuum generator <NUM> is distributed across a larger potential surface area by way of the vacuum distributor <NUM>.

In an exemplary aspect, the vacuum distributor <NUM> is formed from a semi-rigid to rigid material, such as metal (e.g., aluminum) or polymers. However, other materials are contemplated. The vacuum tool <NUM> is contemplated as being manipulated (e.g. moved/positioned) by a robot, such as a multi-axis programmable robot. As such, limitations of a robot may be taken into consideration for the vacuum tool <NUM>. For example, weight of the vacuum tool <NUM> (and/or a manufacturing tool <NUM> to be discussed hereinafter) may be desired to be limited in order to limit the potential size and/or costs associated with a manipulating robot. Utilizing weight as a limiting factor, it may be advantageous to form the vacuum distributor in a particular manner to reduce weight while still achieving a desired distribution of the vacuum force.

Other consideration may be evaluated in the design and implementation of the vacuum tool <NUM>. For example, a desired level of rigidity of the vacuum tool <NUM> may result in reinforcement portions and material removed portions, as will be discussed with respect to <FIG> hereinafter, being incorporated into the vacuum tool <NUM>.

The vacuum distributor <NUM> is comprised of an exterior top surface <NUM> and an exterior side surface <NUM>. <FIG> depicts a vacuum distributor with a substantially rectangular footprint. However, it is contemplated that any footprint may be utilized. For example, a non-circular footprint may be utilized. A non-circular footprint, in an exemplary aspect, may be advantageous as providing a larger useable surface area for manipulating a variety of part geometries. Therefore, the use of a non-circular footprint may allow for a greater percentage of the footprint to be in contact with a manipulated part as compared to a circular footprint. Also with respect to shape of a vacuum tool <NUM> beyond the footprint, it is contemplated, as will be discussed hereinafter, that any three-dimensional geometry may be implemented for the vacuum distributor <NUM>. For example, an egg-like geometry, a pyramid-like geometry, a cubical-like geometry, and the like may be utilized. In an exemplary aspect, a rectangular footprint may provide an easier geometry than a non-rectangular footprint for referencing a location of a part relative to the footprint.

The exemplary vacuum distributor <NUM> of <FIG> is comprised of the exterior top surface <NUM> and a plurality of exterior side surfaces <NUM>. The vacuum distributor <NUM> also terminates at edges resulting in a first side edge <NUM>, a second parallel side edge <NUM>, a front edge <NUM>, and an opposite parallel back edge <NUM>.

The vacuum distributor <NUM>, the vacuum generator <NUM>, and a plate (such as the plate <NUM> to be discussed with respect to <FIG> hereinafter) form a first portion of the vacuum tool <NUM>. This first portion may also be referred to herein as a distributed vacuum tool as the vacuum force is applied over a distributed area as a result of the vacuum distributor <NUM> and the plate <NUM>. This is in contrast to the second vacuum portion <NUM>, which may be referred to as a refined vacuum tool. As will be discussed with respect to <FIG> hereinafter, a refined vacuum tool relies on a fewer number of apertures (e.g., <NUM>, <NUM>, <NUM>, or <NUM>) than the distributed vacuum tool. For example, the refined vacuum tool may have two or a single material contacting aperture (i.e., an aperture through which a vacuum force is useable to manipulate a piece of material at a material contacting surface).

In an exemplary aspect, a distributed vacuum tool utilizes a different and independent vacuum generator than a refined vacuum tool. It is contemplated that a distributed vacuum tool may utilize a coanda-effect (to be discussed in greater detail with respect to <FIG>) vacuum generator while the refined vacuum tool may utilize a venturi-effect vacuum generator. However, it is contemplated that any type of vacuum generator (e.g., coanda, venturi, mechanical, and the like) may be used in any combination. Further, it is contemplated that the distributed vacuum tool may be activated (e.g., generate a vacuum force) independently of an associated refined vacuum tool. As a result, while the distributed vacuum tool is generating a vacuum force, the refined vacuum tool may not be activated (or vice versa). Similarly, it is contemplated that both the distributed vacuum tool and the refined vacuum tool may be activated (and deactivated) concurrently.

A physical coupling of a distributed vacuum tool and a refined vacuum tool may be advantageous in that a common robotic manipulator may be utilized for both vacuum portions without requiring either a substitution of an attached tool on a given robot or the need for an additional robot all together. Further, it is contemplated that the distributed vacuum tool may be utilized for manipulating larger portions of material while the refined vacuum tool may be utilized for manipulating smaller portions of material. For example, time may be saved in a manufacturing process as a result of the distributed vacuum tool picking and placing a larger portion of material (e.g., shoe upper material) and, without having to convey the larger portion of material to a new location, utilizing the refined vacuum tool portion to pick and place a smaller material portion (e.g., accent piece, logo). Further, when an affixing tool is also incorporated, affixing the smaller material portion to the larger material portion without also having to convey or otherwise relocate the grouping of material portions may also be advantageous. Further, the ability to reduce movement of the grouping of material portions may also reduce unintentional shifting and un-alignments of the portions.

<FIG> depicts a cutline <NUM>-<NUM> demarking a parallel view perspective for <FIG> depicts a front-to-back perspective cut view that is parallel along cut line <NUM>-<NUM> of the vacuum tool <NUM>, in accordance with aspects of the claimed invention. <FIG> depicts, among other features, a vacuum distribution cavity <NUM> and a vacuum plate <NUM> (also sometimes referred to as the "plate" herein). The vacuum distributor <NUM> and the plate <NUM>, in combination, define a volume of space forming the vacuum distribution cavity <NUM>. The vacuum distribution cavity <NUM> is a volume of space that allows for the unobstructed flow of gas to allow for an equalized dispersion of a vacuum force. In an exemplary aspect, the flow of gas (e.g., air) from the plate <NUM> to the vacuum generator <NUM> is focused through the utilization of angled interior side surface(s) <NUM>. As depicted in <FIG>, there are four primary interior side surfaces, a first interior side surface <NUM>, a second interior side surface <NUM>, a third interior side surface <NUM>, and a fourth interior side surface <NUM> (not shown). However, it is contemplated that other geometries may be utilized.

The interior side surfaces <NUM> extend from the interior top surface <NUM> toward the plate <NUM>. In an exemplary aspect, an obtuse angle <NUM> is formed between the interior top surface and the interior side surfaces <NUM>. The obtuse angle provides an air vacuum distribution effect that reduces internal turbulence of air as it passes from the plate <NUM> toward a vacuum aperture <NUM> serving the vacuum generator <NUM>. By angling the approach of air as it enters the vacuum aperture <NUM>, a reduced amount of material may be utilized with the vacuum distributor <NUM> (e.g., resulting in a potential reduction in weight) and the flow of air may be controlled through a reduction in air turbulence. However, aspects contemplate a right angle such as that formed by a cube-like structure, a cylinder-like structure and the like.

An angle <NUM> may also be defined by the intersection of the interior side surfaces <NUM> and the plate <NUM>. For example, if the angle <NUM> is obtuse, the angle <NUM> is acute. Again, having an acute angle <NUM> may provide advantages with the flow of air and the ability to reduce/limit weight of the vacuum tool <NUM> in general.

A surface area of the interior top surface <NUM> may be less than a surface area of the exterior plate surface <NUM> when an obtuse angle is utilized between the top surface <NUM> and one or more interior side surfaces <NUM>. This potential discrepancy in surface area serves as a funneling geometry to further reduce turbulence and effectively disperse a vacuum force.

In an exemplary aspect, the interior side surfaces <NUM> are in a parallel relationship with an associated exterior side surface <NUM>. Similarly, in an exemplary aspect the interior top surface <NUM> is in a parallel relationship, at least in part, with the exterior top surface <NUM>. However, it is contemplated that one or more of the surfaces are not in a parallel relationship with an associated opposite surface. For example, if one or more of the interior surfaces are curved in one or more directions, the exterior surface may instead maintain a linear relationship that is, at the most, tangential to the interior surfaces. Similarly, it is contemplated that the interior and exterior surfaces may maintain a parallel (either linear or curved) relationship in part or in whole.

The vacuum aperture <NUM> may include a series of threads allowing the vacuum generator <NUM> to be screwed and secured to the vacuum distribution cavity. Similarly, it is contemplated that other mating patterns (e.g., tapering) may be formed on the interior surface of the vacuum aperture <NUM> and the vacuum generator <NUM> to secure the vacuum generator <NUM> and the vacuum distributor <NUM> together with a air-tight bond.

The plate <NUM>, which will be discussed in greater detail in <FIG> hereinafter, has an interior plate surface <NUM> (i.e., top surface) and an opposite exterior plate surface <NUM> (i.e., bottom surface). The plate <NUM> may be a sheet-like structure, panel-like structure, and/or the like. The exterior plate surface <NUM> is adapted for contacting a part to be manipulated by the vacuum tool <NUM>. For example, the plate <NUM> in general, or the exterior plate surface <NUM> in particular, may be formed from a non-marring material. For example, aluminum or a polymer may be used to form the plate <NUM> in whole or in part. Further, it is contemplated that the plate <NUM> is a semi-rigid or rigid structure to resist forces exerted on it from the vacuum generated by the vacuum generator <NUM>. Therefore, the plate <NUM> may be formed of a material having a sufficient thickness to resist deforming under pressures created by the vacuum generator <NUM>. Further, it is contemplated that the plate <NUM> and/or the vacuum distributor <NUM> are formed from a non-compressible material. Further, it is contemplated that the vacuum tool <NUM> does not form to the contours of a part being manipulated as would a suction-cup like device. Instead, the semi-rigid to rigid material maintain a consistent form regardless of being in contact with a manipulated part or not.

However, it is also contemplated that the plate is formed from a mesh-like material that may be rigid, semi-rigid, or flexible. The mesh-like material may be formed by interlaced material strands made from metal, textile, polymers, and/or the like. Further, it is contemplated that the plate may also be comprised of multiple materials. For example, the plate may be formed from a base structural material (e.g., polymer, metal) and a second part-contacting material (e.g., polymer, foam, textile, and mesh). The multiple-material concept may allow for the plate to realize advantages of the multiple materials selected.

The plate <NUM>, in an exemplary aspect, is coupled, either permanently or temporarily, to the vacuum distributor <NUM>. For example, it is contemplated that the plate <NUM> may be removable/replaceable to allow for adaptability to different materials and specifications. Continuing with this example, and as will be discussed with reference to <FIG>, various aperture sizes, shapes, and spacing may be used depending on the material to be manipulated (e.g., porous materials, non-porous materials, large materials, small materials, dense materials, light materials). If the plate <NUM> is removable (i.e., temporarily coupled), a fastening mechanism may be used (e.g., adhesive, hardware, clamps, channels, and the like) to ensure a tight bond between the plate <NUM> and the vacuum distributor <NUM>. If the plate <NUM> is permanently coupled to the vacuum distributor <NUM>, then known techniques may be used (e.g., welding, bonding, adhesives, mechanical fasteners, and the like).

When used in combination, the vacuum generator <NUM>, the vacuum distributor <NUM>, and the plate <NUM>, the vacuum tool <NUM> is functional to generate a suction force that draws a material towards the exterior plate surface <NUM> (also referred to as a manufacturing-part-contacting surface) where the material is maintained against the plate <NUM> until the force applied to the material is less than a force repelling (e.g., gravity, vacuum) the material from the pate <NUM>. In use, the vacuum tool is therefore able to approach a part, generate a vacuum force capable of temporarily maintaining the part in contact with the plate <NUM>, move the vacuum tool <NUM> and the part to a new location, and then allow the part to release from the vacuum tool <NUM> at the new position (e.g., at a new location, in contact with a new material, at a new manufacturing process, and the like).

In an exemplary aspect, the plate <NUM> (or in particular the exterior plate surface <NUM>) has a surface area that is larger than a material/part to be manipulated. Further, it is contemplated that one or more apertures extending through the plate <NUM> are covered by a part to be manipulated. Stated differently, it is contemplated that a surface area defined by one or more apertures extending through the plate <NUM> exceeds a surface area of a part to be manipulated. Additionally, it is contemplated that a geometry defined by two or more apertures extending through the plate <NUM> results in one or more apertures not contacting (completely or partially) a material/part to be manipulated. As a result, it is contemplated that inefficiency in vacuum force is experienced by the vacuum tool as a result of unusable apertures. However, in an exemplary aspect, the inclusion of unusable apertures is an intended result to allow for a higher degree of latitude in positioning the vacuum tool relative to the part. Further, the intentional inclusion of unusable (unusable for purposes of a particular part to be manipulated (e.g., active vacuum apertures that are ineffective for contacting a portion of the part)) apertures allows for vacuum force leakage while still effectively manipulating a part. In an exemplary aspect, a plurality of apertures extending through a plate <NUM> is further comprised of one or more leaking apertures, an aperture not intended to be used in the manipulation of a part.

The plate <NUM> may have a plurality of apertures (as will be discussed with respect to <FIG>). The distribution of the apertures over the plate provide for a distributed material-contacting surface that is useful in manipulating flexible materials that are large relative to an aperture's size. The refined vacuum tool, on the other hand, provides a smaller selection of apertures (e.g., <NUM>, <NUM>) that are useful for manipulating smaller material portions with a potentially greater level of control than the distributed vacuum tool. As a result, in an exemplary aspect, the refined vacuum tool utilizes (and has) fewer apertures than the distributed vacuum tool.

In an exemplary aspect, it is contemplated that a vacuum tool, such as the vacuum tool <NUM>, is capable of generating a suction force up to <NUM> grams. Further, it is contemplated that the pickup tool <NUM> may have <NUM> grams to <NUM> grams of vacuum (i.e., suction) force. In an exemplary aspect, the pickup tool <NUM> operates with about <NUM> grams of vacuum force. However, it is contemplated that changes in one or more configurations (e.g., vacuum generator, plate, apertures), material of part being manipulated (e.g., flexibility, porosity), and percent of apertures covered by the part may all affect a vacuum force of an exemplary pickup tool. Further, it is contemplated that when multiple distributors are used in conjunction the vacuum force is adjusted commensurately. For example, the pickup tool of <FIG> (to be discussed hereinafter) has ten vacuum distributors and may therefore have a vacuum force of about <NUM> grams to about <NUM> kilograms (<NUM> X <NUM> to <NUM> grams). Similarly, a pickup tool having <NUM> vacuum distributors may have a suction force of about <NUM> grams (<NUM> X <NUM> grams). However, it is contemplated that air pressure/volume supplied to the vacuum generators is not affected by a plurality of generators operating simultaneously. If an air pressure or value is reduced (or otherwise altered) it is contemplated that a resulting cumulative vacuum force is also altered.

The multi-aperture vacuum tool <NUM> of <FIG> is further comprised of the second vacuum portion <NUM>. As previously discussed, the second vacuum portion <NUM> may also be referred to as a refined vacuum tool. The refined vacuum tool is physically coupled to the distributed vacuum tool by way of a coupling member <NUM>. The coupling member <NUM> allows for the physical coupling of the refined vacuum tool and the distributed vacuum tool such that both may move as a common article. While the coupling member is depicted as coupling directly to the vacuum distributor <NUM>, it is contemplated that the coupling member <NUM> may directly couple to any portion of the vacuum tool <NUM> (e.g., coupling member <NUM> of <FIG>, an affixing tool, or any other portion discussed herein).

While the refined vacuum tool <NUM> is depicted as being coupled at a particular location and at a particular orientation relative to the distributed vacuum tool, it is contemplated that the refined vacuum tool may be positioned at any location and at any orientation. For example, the refined vacuum tool may be located along a median bisecting a geometric center of the vacuum tool <NUM> (or the vacuum distributor <NUM>). Similarly, it is contemplated that the refined vacuum tool is positioned at a corner of the vacuum distributor <NUM>. Further yet, it is contemplated that the refined vacuum tool is positioned such that, as depicted in <FIG>, a material-contacting surface <NUM> is in a common plane as the plate <NUM>. This common plane may be referred to herein as a material contact plane. Further, while only one refined vacuum tool is depicted in <FIG>, it is contemplated that the vacuum tool <NUM> may be comprised of any number and at any location (e.g., see <FIG> hereinafter).

The second vacuum portion <NUM> (i.e. refined vacuum tool) is similar to the vacuum tool <NUM> discussed hereinafter with respect to <FIG>. For example, it is contemplated that the refined vacuum tool is a venturi-effect based vacuum tool having one or two apertures. The second vacuum portion <NUM> is depicted as having a single aperture <NUM>; however, it is contemplated that the refined vacuum tool may utilize two apertures, such as that depicted in <FIG>, <FIG>, <FIG>. Further, it is contemplated that the refined vacuum tool may utilize four apertures or three apertures to achieve a desired level of material handling stability (e.g., resistance to material shifting and rotation based on tool movement). As will be discussed in greater detail with respect to <FIG> hereinafter, the aperture <NUM> of the refined vacuum tool may be any shape and diameter. For example, the diameter may be the same, smaller, or greater than one or more apertures of the distributed vacuum tool. In an exemplary aspect, the aperture may be five times, four times, three times, or the same size as an aperture of the distributed vacuum tool. The size represents an area exposed to a piece of material proximate the material contacting surface <NUM>. Therefore, it is contemplated that in an exemplary aspect, the aperture <NUM> of the refined vacuum tool may have a diameter of <NUM> millimeters to <NUM> millimeter. However, other sizes larger and smaller are also contemplated.

<FIG> depicts a front-to-back view of the vacuum tool <NUM> along the cutline <NUM>-<NUM> of <FIG>, in accordance with aspects of the claimed invention. In particular, <FIG> provides a cut view of the vacuum generator <NUM>. As will be discussed in greater detail with respect to <FIG>, the vacuum generator <NUM>, in the exemplary aspect, is an air amplifier utilizing a coandǎ effect to generate a vacuum force.

In this example, air is drawn from the exterior plate surface <NUM> through a plurality of apertures <NUM> through the plate <NUM> to the vacuum distribution cavity <NUM>. The vacuum distribution cavity <NUM> is enclosed between the vacuum distributor <NUM> and the plate <NUM>, such that if the plate <NUM> is a non-porous (i.e., lacked the plurality of apertures <NUM>) surface, then an area of low pressure would be generated in the vacuum distribution cavity <NUM> when the vacuum generator <NUM> is activated. However, returning to the example including the plurality of aperture <NUM>, the air is drawn into the vacuum distribution cavity <NUM> towards the vacuum aperture <NUM>, which then allows the air to be drawn into the vacuum generator <NUM>.

<FIG> identifies a zoomed view of the vacuum generator <NUM> depicted in <FIG> depicts a focused view of the vacuum generator <NUM> as cut along the cutline <NUM>-<NUM> from <FIG>, in accordance with aspects of the claimed invention. The vacuum generator depicted in <FIG> is a coandǎ effect (i.e., air amplifier) vacuum pump <NUM>. The coandǎ effect vacuum pump injects pressurized air at an inlet <NUM>. The inlet <NUM> directs the pressurized air through an internal chamber <NUM> to a sidewall flange <NUM>. The pressurized air, utilizing the coandǎ effect, curves around the sidewall flange <NUM> and flows along an internal sidewall <NUM>. As a result of the pressurized air movement, a vacuum force is generated in the same direction as the flow of the pressurized air along the internal sidewall <NUM>. Consequently, a direction of suction extends up through the vacuum aperture <NUM>.

<FIG> depicts an exemplary plate <NUM> comprised of the plurality of apertures <NUM>, in accordance with aspects of the claimed invention. While the plate <NUM> is illustrated as having a rectangular footprint, as previously discussed, it is contemplated that any geometry may be implemented (e.g., circular, non-circular) depending, in part, on the material to be manipulated, a robot controlling the vacuum tool <NUM>, and/or components of the vacuum tool <NUM>. Further, it is contemplated that in exemplary aspects a first plate may be substituted for a second plate on the vacuum tool. For example, rather than switching out an entire vacuum tool as a result of a change in material, parts, etc., the plate <NUM> may instead be changed on a particular vacuum tool to provide alternative characteristics to the vacuum tool (e.g., a first plate may have a few large apertures and a second plate may have many small apertures).

The plurality of apertures <NUM> may be defined, at least in part, by a geometry (e.g., circular, hatch, bulbous, rectangular), size (e.g., diameter, radius (e.g., radius <NUM>), area, length, width), offset (e.g., offset <NUM>) from elements (e.g., distance from outer edge, distance from a non-porous portion), and pitch (e.g., distance between apertures (e.g., pitch <NUM>)). The pitch of two apertures is defined as a distance from a first aperture (e.g., first aperture <NUM>) to a second aperture (e.g., second aperture <NUM>). The pitch may be measured in a variety of manners. For example, the pitch may be measured from the closest two points of two apertures, from the surface area center of two apertures (e.g., centre of circular apertures), from a particular feature of two apertures.

The size of the apertures may be defined based on an amount of surface area (or a variable to calculate surface area) exposed by each aperture. For example, a diameter measurement provides an indication of a circular aperture's size.

Depending on desired characteristics of a vacuum tool, the variables associated with the apertures may be adjusted. For example, a non-porous material of low density may not require much vacuum force to maintain the material in contact with the vacuum tool under normal operating conditions. However, a large porous mesh material may, on the other hand, require a significant amount of vacuum force to maintain the material against the vacuum tool under normal operating conditions. Therefore, to limit the amount of energy placed into the system (e.g., amount of pressurized air to operate a coandǎ effect vacuum pump, electricity to operate a mechanical vacuum pump) an optimization of the apertures may be implemented.

For example, a variable that may be sufficient for typical materials handled in a footwear, apparel, and the like industry may include, but not be limited to, apertures having a diameter between <NUM> and <NUM> millimeters (mm), between <NUM> and <NUM>, between <NUM> and <NUM>, <NUM>, <NUM>, <NUM>, <NUM>, and the like. However, larger and smaller diameter (or comparable surface area) apertures are contemplated. Similarly, the pitch may range between <NUM> and <NUM>, between <NUM> and <NUM>, between <NUM> and <NUM>, <NUM>, <NUM>, <NUM>, <NUM>, <NUM>, <NUM>, <NUM>, and the like. However, larger and smaller pitch measurements are contemplated.

Additionally, it is contemplated that a variable size and a variable pitch may be implemented in aspects of the claimed invention. For example, a compound part composed of both a porous material portion and a non-porous material portion may utilize different variables to accomplish the same level of manipulation. In this example, variables that lead to a reduction in necessary vacuum force in an area to be contacted by the non-porous material and variable that lead to higher vacuum forces in an area to be contacted by the porous material may be implemented. Further, a vision system or other identification system may be used in conjunction to further ensure a proper placement of the material with respect to the plurality of apertures occurs. Additionally, it is contemplated that a relationship between pitch and size may be utilized to locate the plurality of apertures. For example, a pitch from a larger sized aperture may be greater than a pitch from a smaller sized aperture (or vice versa).

An additional variable is the offset. In an exemplary aspect, the offset is a distance of an aperture from an outside edge of the plate <NUM>. Different apertures may have different offsets. Further different edges may implement different offsets. For example an offset along a front edge may be different from an offset along a side edge. The offset may range from no offset to <NUM> (or more). In practice, an offset ranging from <NUM> to <NUM> may accomplish characteristics of exemplary aspects of the claimed invention.

The plurality of apertures <NUM> may be formed in the plate <NUM> utilizing a number of manufacturing techniques. For example apertures may be punched, drilled, etched, carved, melted, and/or cut from the plate <NUM>. In an exemplary embodiment, the plate <NUM> is formed from a material that is responsive to laser cutting. For example polymer-based materials and some metal-based materials may be used in conjunction with laser cutting of the plurality of apertures. Further, it is contemplated that the geometry of the apertures may be variable as the aperture extends through the thickness of the plate. For example, the aperture may have a diameter of a first size on a top surface of the plate and a diameter of a second size at the opposite bottom surface of the plate. This variable in geometry mat result in a conical geometry extending through the plate. Additional geometries are contemplated herein (e.g., pyramid).

<FIG> provide exemplary aperture variable selections similar to that discussed with respect to <FIG>, in accordance with aspects of the claimed invention. The following examples are not intended to be limiting, but instead exemplary in nature. <FIG> depicts non-circular apertures having a first offset of <NUM> and a second offset of <NUM> and a pitch of <NUM>. <FIG> depicts circular apertures having an offset and pitch of <NUM> with a diameter of <NUM>. <FIG> depicts circular apertures having a diameter of <NUM>, a pitch of <NUM>, and offsets of <NUM> and <NUM>. <FIG> depicts circular apertures having a diameter of <NUM>, a pitch of <NUM>, and offsets of <NUM> and <NUM>. <FIG> depicts exemplary geometric apertures having a pitch of <NUM> and offsets of <NUM>. <FIG> depicts circular apertures having a diameter of <NUM>, a pitch of <NUM>, and offsets of <NUM> and <NUM>. <FIG> depicts circular apertures having a diameter of <NUM>, a pitch of <NUM>, and offsets of <NUM>. <FIG> depicts circular apertures having a diameter of <NUM>, a pitch of <NUM>, and offsets of <NUM> and <NUM>. <FIG> depicts circular apertures having a diameter of <NUM>, a pitch of <NUM>, and offsets of <NUM>. <FIG> depicts circular apertures having a diameter of <NUM>, a pitch of <NUM>, and offsets of <NUM> and <NUM>. As previously discussed, it is contemplated that shape, size, pitch, and offset may be altered uniformly or variably in any combination to achieve a desired result.

Depending on the footprint of the plate <NUM>, the offset, the pitch, the geometry of the apertures, the layout of the apertures, and the size of the apertures, any number of apertures may be utilized. For example, it is contemplated that the plate <NUM> of <FIG> may have <NUM>,<NUM> to <NUM>,<NUM> apertures. In a particular aspect, it is contemplated around <NUM>,<NUM> apertures are utilized on the plate <NUM> of <FIG>. Further, the plate <NUM> of <FIG> (discussed hereinafter) may be comprised of <NUM>,<NUM> to <NUM>,<NUM> apertures. In particular, it is contemplated that <NUM>,<NUM> apertures may be included in an exemplary plate <NUM> of <FIG>.

Changes to the vacuum generator <NUM>, the plate <NUM>, and the overall size of the vacuum tool <NUM> may affect the air consumption and pressure when utilizing a coandǎ effect vacuum pump or a venturi vacuum pump For example, it is contemplated that a given coandǎ effect vacuum pump may generate <NUM>/cm<NUM> of vacuum force. To accomplish this level of vacuum, it is contemplated that a pneumatic pressure of <NUM> to <NUM> MPa of pressure are introduced to the vacuum tool. The volume of air consumption to generate sufficient vacuum may also vary based on the variables. For example, it is contemplated that <NUM>,<NUM> Nl/min of air consumption may be utilized for the vacuum tool <NUM> of <FIG>. Further, it is contemplated that <NUM> Nl/min of air consumption may be utilized for the vacuum tool <NUM> of <FIG> (to be discussed hereinafter). Further, it is contemplated that <NUM> Nl/min of air consumption may be utilized for the vacuum tool <NUM> of <FIG> (to be discussed hereinafter). As previously discussed, the footprint (e.g., surface area of the plate <NUM>) may also affect vacuum force, air consumption, and the like. For example, it is contemplated that the plate <NUM> of <FIG> may have a footprint approximately of <NUM> by <NUM>. Similarly, it is contemplated that the plate <NUM> of <FIG> may have a footprint approximately of <NUM> by <NUM>. Clearly, it is contemplated that the proportions of a vacuum distributor may be altered based on a desired level of vacuum force, footprint, and additional variables.

<FIG> depicts an exploded view of a manufacturing tool <NUM> comprised of a vacuum tool <NUM>, a refined vacuum tool <NUM>, and an ultrasonic welder <NUM>, in accordance with aspects of the claimed invention. Unlike the vacuum tool <NUM> discussed with respect to <FIG>, the vacuum tool <NUM> of <FIG> incorporates a plurality of vacuum generators <NUM>, vacuum distributors <NUM>, and vacuum distribution cavities <NUM> into a unified vacuum tool <NUM>. As will be discussed hereinafter, advantages may be realized by the ability to selectively activate/deactivate vacuum force in individual portions of the vacuum tool <NUM>. Additionally, a greater control of continuous vacuum force may be achieved by having segregated portions of the vacuum tool <NUM>.

The manufacturing tool <NUM> also is comprised of a coupling member <NUM>. The coupling member <NUM> is a feature of the manufacturing tool <NUM> (or the vacuum tool <NUM> or the ultrasonic welder <NUM> individually) allowing a positional member <NUM> (not shown) to manipulate the position, attitude, and/or orientation of the manufacturing tool <NUM>. For example, the coupling member <NUM> may allow for the addition of the manufacturing tool to a computer-numerically-controlled (CNC) robot that has a series of instruction embodied on a non-transitory computer-readable medium, that when executed by a processor and memory, cause the CNC robot to perform a series of steps. For example, the CNC robot may control the vacuum generator(s) <NUM>, the ultrasonic welder <NUM>, and/or the position to which the manufacturing tool <NUM> is located. The coupling member <NUM> may, therefore, allow for the temporary or permanent coupling of the manufacturing tool <NUM> to a positional member <NUM>, such as a CNC robot.

As was previously discussed, aspects of the claimed invention may form portions of the manufacturing tool <NUM> with the intention of minimizing mass. As such, the plurality of vacuum distributors <NUM> of <FIG> include reduced material portions <NUM>. The reduced material portions <NUM> eliminate portions of what could otherwise be a uniform exterior top surface. The introduction of reduced material portions <NUM> reduces weight of the manufacturing tool <NUM> to allow for a potentially smaller positional member <NUM> to be utilized, which may save on space and costs. Additional locations for reduced material portions <NUM> are contemplated about the vacuum tool <NUM> (e.g., side, bottom, top).

However, aspects of the claimed invention may desire to remain a level of rigidity of the plurality of vacuum distributors <NUM> as supported by a single coupling member <NUM>. To maintain a level of rigidity while still introducing the reduced material portions <NUM>, reinforcement portions <NUM> may also be introduced. For example, reinforcement portions <NUM> may extend from one vacuum distributor <NUM> to another vacuum distributor <NUM>. Further yet, it is contemplated that in aspects of the claimed invention, reinforcement portions <NUM> may be included proximate the coupling member <NUM> for a similar rationale.

The plate <NUM> is separated from the plurality of vacuum distributors <NUM> in <FIG> for illustrative purposes. As a result, an interior plate surface <NUM> is viewable. In an exemplary aspect, the interior plate surface <NUM> is mated with a bottom portion of the plurality of vacuum distributors <NUM>, forming an air-tight bond.

The vacuum tool <NUM> is comprised of a plurality of vacuum generators <NUM>, vacuum distributors <NUM>, and associated vacuum distribution cavities <NUM>. It is contemplated that any number of each may be utilized in a vacuum tool <NUM>. For example, it is contemplated that <NUM>, <NUM>, <NUM>, <NUM>, <NUM>, <NUM>, or any number of units may be combined to form a cohesive vacuum tool <NUM>. Further, any footprint may be formed. For example, while a rectangular footprint is depicted in <FIG>, it is contemplated that a square, triangular, circular, non-circular, part-matching shape, or the like may instead be implemented. Additionally, the size of the vacuum generator <NUM> and/or the vacuum distributor <NUM> may be varied (e.g., non-uniform) in various aspects. For example, in an exemplary aspect, where a greater concentration of vacuum force is needed for a particular application, a smaller vacuum distributor may be utilized, and where a less concentrated vacuum force is needed, a larger vacuum distributor may be implemented.

The manufacturing tool <NUM> is depicted as having the refined vacuum tool <NUM> coupled to the vacuum tool <NUM> by way of the ultrasonic welder <NUM>. However, it is contemplated that the refined vacuum tool <NUM> may, instead, be coupled at any location and at any orientation directly or indirectly to one or more portions of the vacuum tool <NUM>,.

<FIG> depict exemplary manufacturing tools <NUM>; however, it is understood that one or more components may be added or removed from each aspect. For example, each aspect is comprised of an ultrasonic welder <NUM>, a refined vacuum tool <NUM>, and a vacuum tool <NUM>, but it is contemplated that the ultrasonic welder may be eliminated all together and additional refined vacuums may be added or subtracted. Further, it is contemplated that additional features may also be incorporated. For example, vision systems, adhesive applicators (e.g., spray, roll, and other application methods), mechanical fastening components, pressure applicators, curing devices (e.g., ultraviolet light, infrared light, heat applicators, and chemical applicators), and the like may also be incorporated in whole or in part in exemplary aspects. As used herein, an affixing tool is a tool category comprised of adhesive applicators, mechanical fastening components, pressure applicators, curing devices, and the like.

The ultrasonic welder <NUM>, in an exemplary aspect, is comprised of a stack comprised of an ultrasonic welding horn <NUM> (may also be referred to as a sonotrode), a converter <NUM> (may also be referred to as a piezoelectric transducer), and a booster (not labeled). The ultrasonic welder <NUM> may further be comprised of an electronic ultrasonic generator (may also be referred to as a power supply) and a controller. The electronic ultrasonic generator may be useable for delivering a high-powered alternating current signal with a frequency matching the resonance frequency of the stack (e.g., horn, converter, and booster). The controller controls the delivery of the ultrasonic energy from the ultrasonic welder to one or more parts.

Within the stack, the converter converts the electrical signal received from the electronic ultrasonic generator into a mechanical vibration. The booster modifies the amplitude of the vibration from the converter. The ultrasonic welding horn applies the mechanical vibration to the one or more parts to be welded. The ultrasonic welding horn is comprised of a distal end <NUM> adapted for contacting a part.

<FIG> depicts a top-down view of the manufacturing tool <NUM> previously depicted in <FIG>, in accordance with aspects of the claimed invention. The top perspective of <FIG> provides an exemplary view of a potential orientation of a plurality of vacuum distributors <NUM> to form a vacuum tool <NUM>. As will be discussed hereinafter with respect to <FIG>, various vacuum generator <NUM>/vacuum distributor <NUM> combinations may be selectively activated and/or deactivated to manipulate particular parts.

<FIG> depicts a side-perspective view of the manufacturing tool <NUM> previously depicted in <FIG>, in accordance with aspects of the claimed invention.

<FIG> depicts an exploded-perspective view of a manufacturing tool <NUM> comprised of six discrete vacuum distributors <NUM>, three refined vacuum tools <NUM>, and an ultrasonic welder, in accordance with aspects of the claimed invention. The plate <NUM> is depicted in this exemplary aspect as having a plurality of apertures <NUM> and non-aperture portions <NUM>. The non-aperture portion <NUM> is a portion of the plate <NUM> through which apertures do not extend. For example, along a segment where two vacuum distributors <NUM> converge the plate <NUM> may include a non-aperture portion <NUM> to prevent cross feeding of vacuum between two associated vacuum distribution cavities <NUM>. Further, it is contemplated that non-aperture portion <NUM> may extend along a segment in which the plate <NUM> is bonded (temporarily or permanently) to one or more portions of the vacuum distributor(s) <NUM>. Further yet, it is contemplated that one or more non-aperture portions are integrated into the plate <NUM> to further control the placement of vacuum forces as dispersed along the exterior plate surface <NUM>. Additionally, the non-aperture portion <NUM> may be implemented in an area intended to be in contact with pliable (and other characteristics) portions of material that may not react well to the application of vacuum as transferred by one or more apertures.

The three refined vacuum tools are identified as <NUM>, <NUM>, and <NUM>. As previously discussed, it is contemplated that any number of refined vacuum tools may be utilized at any location and at any orientation. As depicted in <FIG>, it is contemplated that the refined vacuum tool <NUM> is in a first quadrant surrounding the ultrasonic welder <NUM>, the refined vacuum tool <NUM> is in a second quadrant, and the refined vacuum tool <NUM> is in a third quadrant. In this configuration, the vacuum tool <NUM> occupies a fourth quadrant. Therefore, it is contemplated that one or more refined vacuum tools may be located around one or more portions of a manufacturing tool. In an exemplary aspect, having two or more refined vacuum tools surrounding features of a manufacturing tool may reduce tool movement necessary to manipulate a desired material (e.g., allowing a vacuum tool to be closer to the desired point of contact on the material at given points in space for the manufacturing tool). In this example, each of the refined vacuum tools may be independent of one another; however, it is also contemplated that one or more refined vacuum tools may be dependent on one or more other vacuum tools (refined or distributed).

<FIG> depicts a top-down perspective of the manufacturing tool <NUM> previously discussed with respect to <FIG>, in accordance with exemplary aspects of the claimed invention. In particular six discrete vacuum tool portions are identified as a first vacuum portion <NUM>, a second vacuum portion <NUM>, a third vacuum portion <NUM>, a fourth vacuum portion <NUM>, a fifth vacuum portion <NUM>, and a fifth vacuum portion <NUM>. In an exemplary aspect of the claimed invention, one or more vacuum portions may be selectively activated and deactivated. It is understood that this functionality may be applied to all aspects provided herein, but are only discussed with respect to the present <FIG> for brevity reasons.

In particular, it is contemplated that if a part (e.g., manufacturing part to be manipulated by the manufacturing tool <NUM>) only requires a portion of the entire footprint of the vacuum tool <NUM>, then unused portions of the vacuum tool <NUM> may be de-activated (or abstained from activating) such that vacuum force is not generated in those portions. In addition, it is contemplated that a placement jig, vision systems, known part-transfer location, and the like may be utilized to further aid in determining which portions of the vacuum tool <NUM> may be selectively activated/deactivated. For example, if a part to be manipulated by the manufacturing tool has a surface area that only requires the activation of two vacuum tool portions, then it may be advantageous to utilize vacuum tool portions <NUM> and <NUM>, vacuum portions <NUM> and <NUM>, or vacuum portions <NUM> and <NUM>. The determination of which vacuum portions may depend on the distance the manufacturing tool is required to move from a position to locate the activated portions over the part. Additionally, the determination may depend on the location of one or more tools (e.g., ultrasonic welder <NUM>) that will be applied to the manipulated parts (e.g., it may be advantageous to utilize two vacuum portions close to the ultrasonic welder <NUM> when the ultrasonic welder <NUM> is intended to be utilized after the manipulation).

The control of the various vacuum portions may be accomplished utilizing a computing system having a processor and memory. For example, logic, instructions, method steps, and/or the like may be embodied on a computer-readable medium, that when executed by the processor, cause the various vacuum portions to activate/deactivate.

Another distinction between a distributed vacuum tool and a refined vacuum tool may be identified based on the utilization of available apertures. Generally, the distributed vacuum tool will have one or more apertures that are not obscured by a part being manipulated. In this regard, the distributed vacuum tool is designed with an anticipated loss in vacuum pressure about an internal cavity while manipulating a part as a result of one or more non-covered apertures. To the contrary, the refined vacuum tool may be designed so that all apertures are able to be obscured by a part being manipulated. In this sense, the refined vacuum tool may be designed with an expectation of a higher efficiency in vacuum pressure usage based on the anticipated complete use of apertures. Stated differently, in an exemplary aspect the distributed vacuum tool, when in a part manipulation state, has a greater number of un-obscured apertures than a refined vacuum tool that is also (but not necessarily contemporaneously) in a part manipulation state. Stated from yet another exemplary perspective, it is contemplated that the distributed vacuum tool allows more air to pass through the collection of associated apertures when in a part-manipulation state than does a refined vacuum tool when in a part-manipulation state.

As previously discussed, it is contemplated that a refined vacuum tool portion and a distributed vacuum tool portion are operable for manipulating a part independently. Additionally, it is contemplated that the refined vacuum tool and the distributed vacuum tool may be used contemporaneously on a common part or different parts. In addition, as will be discussed with respect to <FIG> hereinafter, it is contemplated that the refined vacuum tool portion may be moved out of a working plane used by the distributed vacuum tool to allow for independent use of the distributed vacuum tool or contemporaneous use of the refined and distributed vacuum tools.

Further, it is contemplated that a vision system either capturing an image top-down or bottom-up may be incorporated for identifying the location of a part, the location of a tool (e.g., ultrasonic tool, vacuum tool), alignment of one or more portions (e.g., alignment of a part relative to a tool), placement of a part, orientation of a part, and the like. In an exemplary aspect, a top-down camera perspective is used with a refined vacuum tool and a bottom-up perspective is used with a distributed vacuum tool. This arrangement may be utilized to prevent the distributed vacuum tool from obscuring the part and for the part from obscuring the refined vacuum tool. In an additional aspect, both tools use a common perspective. Further, it is contemplated that any combination of a camera perspective may be implemented.

A refined vacuum tool may be associated with a pressure sensor. The pressure sensor, in an exemplary aspect is functional for detecting if a part is being manipulated and if the part is being properly manipulated. For example, when the refined vacuum tool exerts a vacuum force on a part a first level of pressure is experienced when air is allowed to move into the apertures of the vacuum tool. Once a part is blocking one or more of the apertures, a different pressure is experienced as a result of limited air flow through the apertures. In an exemplary aspect, this pressure differential may be measured by a pressure sensor measuring a pressure of an internal cavity of the refined vacuum tool. When a part is being manipulated and blocking one or more apertures a greater pressure may be experienced at the internal cavity than when the one or more apertures are not obstructed by the part. Further, a different level of pressure may be experienced when a part is not properly aligned and the anticipated apertures are not properly in contact with the part. If too many of the apertures are obscured because of a misalignment of the part, then the pressure may be higher (i.e., a greater amount of vacuum pressure) than anticipated. If too few of the apertures are obscured by a misaligned part then the pressure may be lower (i.e., a lesser amount of vacuum pressure) than anticipated. It is contemplated that the pressure sensor may be used as a quality control mechanism to ensure alignment and other characteristics of the part and tools. Further, it is contemplated that the pressure sensor may also be incorporated, in addition or in the alternative, to a distributed vacuum tool. The pressure sensor may be used to control aspects of the vacuum tool (e.g., amount of vacuum pressure, movement of the tool, activation of other tool portions, and the like). Other sensors are also contemplated, such a force sensors and the like.

<FIG> depicts a side perspective of the manufacturing tool <NUM> of <FIG>, in accordance with aspects of the claimed invention.

<FIG> depicts a manufacturing tool <NUM> comprised of a vacuum tool <NUM> and an ultrasonic welder <NUM>, in accordance with aspects of the claimed invention. In an exemplary aspect, the vacuum tool <NUM> is a refined vacuum tool. In particular, the vacuum tool <NUM> of <FIG> utilizes a venturi vacuum generator <NUM>. A venturi vacuum generator, similar to a coandǎ effect vacuum pump, utilizes pressurized air to generate a vacuum force. The vacuum tool <NUM> of <FIG> differs from the vacuum tool <NUM> of the previously discussed figures in that the vacuum tool <NUM> of <FIG> utilizes a single aperture as opposed to a plate having a plurality of apertures. In an exemplary aspect, the concentration of vacuum force to a single aperture may allow for higher degree of concentrated part manipulation. For example, small parts that may not require even a whole single portion of a multi-portion vacuum tool to be activated may benefit from manipulation by the single aperture vacuum tool of <FIG>.

The single aperture vacuum tool of <FIG> utilizes a cup <NUM> for transferring the vacuum force from the venturi vacuum generator <NUM> to a manipulated part. The cup <NUM> has a bottom surface <NUM> that is adapted for contacting a part. For example, a surface finish, surface material, or size of the bottom surface may be suitable for contacting a part to be manipulated. The bottom surface <NUM> may define a plane similar to the plane previously discussed as being defined from the exterior plate surface <NUM> of <FIG>, for example. As such, it is contemplated that the distal end <NUM> of the ultrasonic welder <NUM> may be defined relative to the plane of the bottom surface <NUM>.

It is contemplated that the cup <NUM> may be adjusted based on a part to be manipulated. For example, if a part has a certain shape, porosity, density, and/or material, then a different cup <NUM> may be utilized. Further, it is contemplated that the cup <NUM> is incorporated into a refined vacuum tool as discussed with respect to <FIG>, <FIG>, and <FIG>. Therefore, as discussed herein, a material contacting surface for a refined vacuum tool may include a cup, such as the cup <NUM>. Further, when discussing an aperture, the aperture of a refined vacuum tool may also include the cup.

While two discrete combinations of a vacuum tool <NUM> with an ultrasonic welder <NUM> are depicted as forming the manufacturing tool <NUM> of <FIG>, it is contemplated that any number of features may be implemented. For example, a plurality of vacuum tools <NUM> may be utilized in conjunction with a single ultrasonic welder <NUM>. Similarly, it is contemplated that a plurality of ultrasonic welders <NUM> may be implemented in conjunction with a single vacuum tool <NUM>. Further, it is contemplated that various types of vacuum tools may be implemented in conjunction. For example, a manufacturing tool <NUM> may be comprised of a single aperture vacuum tool and a multi-aperture vacuum tool (e.g., <FIG>). As such, any number of features (e.g., tools) may be combined.

<FIG> depicts a top-down perspective of the manufacturing tool of <FIG>, in accordance with aspects of the claimed invention.

<FIG> depicts a side perspective of the manufacturing tool of <FIG>, in accordance with aspects of the claimed invention. An offset distance <NUM> may be adjusted for the manufacturing tool <NUM>. The offset distance <NUM> is a distance between the distal end <NUM> of the ultrasonic welder <NUM> and the cup <NUM>.

<FIG> depicts a cut side perspective view of a manufacturing tool <NUM> comprised of a single aperture <NUM> and an ultrasonic welder <NUM>, in accordance with aspects of the claimed invention. The manufacturing tool <NUM> of <FIG> incorporates a moveable coupling mechanism by which the ultrasonic welder <NUM> is allowed to slide in a direction perpendicular to a plane defined by the bottom surface <NUM>. To accomplish this exemplary moveable coupling, a biasing mechanism <NUM> is implemented to regulate an amount of pressure the distal end <NUM> exerts on a part, regardless of pressure being exerted in the same direction by way of the coupling member <NUM>. In this example, a flange <NUM> slides in a channel that is opposed by the biasing mechanism <NUM>. While a spring-type portion is illustrated as the biasing mechanism <NUM>, it is contemplated that any mechanism may be implemented (e.g., gravity, counter weight, pneumatic, hydraulic, compressive, tensile, and the like).

In use, it is contemplated that a force may be exerted onto a part by the manufacturing tool <NUM> that is greater than necessary for the welding of the part by the ultrasonic welder <NUM>. As a result, the greater force may be effective for maintaining a part during a welding operation, while the biasing mechanism <NUM> may be used to apply an appropriate pressure force for a current welding operation. For example, it is contemplated that the biasing mechanism <NUM> may allow for movement of the distal end <NUM> over a range of distances. For example, the range may include <NUM> to <NUM>, <NUM>-<NUM>, and/or about <NUM>. Further, it is contemplated that the biasing mechanism may also be used as a dampening mechanism to reduce impact forces experienced by one or more portions of the manufacturing tool <NUM> when contacting objects (e.g., parts, work surface).

Further, it is contemplated that the vacuum tool <NUM> is alternatively or additionally implementing a biasing mechanism. For example, in an exemplary aspect of the claimed invention, the amount of pressure exerted by the vacuum tool <NUM> may be desired to be less than a pressure exerted by the distal end <NUM> on the part. As a result, a form of biasing mechanism <NUM> may be employed to controllably exert pressure on to a part by the vacuum tool <NUM>.

An amount of force that may be exerted by a distal end having a biasing mechanism (or not having a biasing mechanism) may range from <NUM> grams to <NUM> grams. For example, it is contemplated that the amount of force exerted by the distal end on a part may increase as an amount of distance traveled by a biasing mechanism increases. Therefore, a relationship (e.g., based on a coefficient of the biasing mechanism) may dictate an amount of pressure applied based on a distance traveled. In an exemplary operation, such as affixing a base material, a mesh material, and a skin during a welding operation, about <NUM> grams of force may be exerted. However, it is contemplated that more or less force may be utilized.

<FIG> depicts a perspective view of a manufacturing tool <NUM> comprised of a multi-aperture vacuum tool <NUM> and an ultrasonic welder <NUM>, in accordance with aspects of the claimed invention. While it is contemplated that features of the manufacturing tool <NUM> are similar to those discussed hereinabove with other manufacturing tools, the multi-aperture vacuum tool <NUM> provide two discrete apertures <NUM> and <NUM>. The plurality of apertures, in an exemplary aspect, allows for greater control and placement of material by providing a second discrete point of contact between the vacuum tool and the material.

It is contemplated that the aperture <NUM> and the aperture <NUM> rely on a common vacuum-force generator to produce a vacuum pressure allowing a material to be manipulated by the vacuum tool. Further, it is contemplated that the aperture <NUM> and the aperture <NUM> each have an independent vacuum-force generator to produce the vacuum pressure. As discussed previously, the vacuum force may be generated utilizing a suitable generator/technique (e.g., mechanical, coanda, and/or venturi).

<FIG> also depicts a cutline <NUM>-<NUM> bisecting the manufacturing tool <NUM> along an internal plane.

<FIG> depicts an internal view of a manufacturing tool <NUM> along the cutline <NUM>-<NUM> of <FIG>, in accordance with aspects of the claimed invention. While specific geometries are depicted in the <FIG>, it is understood that any geometry may be implemented. For example, a support member <NUM> used to support both the aperture <NUM> and the aperture <NUM> of the vacuum tool <NUM> may be of any size, shape, and/or orientation to achieve a desired manipulation of a material. For example, a distance <NUM> between the aperture <NUM> and the aperture <NUM> may be greater or smaller depending on a number of factors. For example, the size, shape, porosity, and/or manipulation-to-be-done of a material may benefit from a greater spread or a lesser spread than the distance <NUM>. In an exemplary aspect, when a rotational manipulation (e.g., rotation about a vertical axis through the manufacturing tool <NUM>) of the material is to occur, it may be beneficial to have a greater spread to resist rotational momentum of the material from altering how the material is positioned relative to the manufacturing tool <NUM>. In another example, if the material to be manipulated is small, a smaller spread between the apertures may be desired to ensure a greater contact area.

In further aspects, it is contemplated that additional apertures comprise a multi-aperture vacuum tool. For example, three, four, or more apertures may be used in combination to achieve a manipulation of a material. Further, it is contemplated that additional relationships may be implemented. For example, a first aperture may be adjacent a first side of a welding tool and a second aperture may be adjacent to a second (different) side of the welding tool (e.g., apertures located at two or more points around an ultrasonic welding horn).

Additionally, it is contemplated that the aperture <NUM> and the aperture <NUM> are of different sizes. For example, a first of the apertures may be larger and capable of generating a greater bonding force with the material such that the larger aperture is primarily responsible for the manipulation of the material. In this example, the second smaller aperture provides a stabilizing bonding force to resist unintentional movement of the material. For example, a larger aperture (e.g., greater diameter) may be positioned at a location on the material that is conducive to manipulate the material (e.g., center of mass, geometric center, etc) and the second aperture is offset to provide better leveraged control over rotational or other movements of the material.

Further yet, it is contemplated that the first aperture and the second aperture may provide varied levels of vacuum force. For example, a first aperture may generate a greater vacuum force (e.g., have a greater discrepancy between ambient air pressure and pressure passing through the aperture) that the second aperture. This may be accomplished in a variety a contemplated manners. For example, when a coanda and/or a venturi-based vacuum generator is used, the volume of air and/or the pressure of the air may be increased to increase a vacuum generated (or decreased to decrease a vacuum force generated). Further, it is contemplated that one or more valves (or other selective adjustments) may be utilized (with respect to any aperture provided herein) to restrict an amount of vacuum force experienced at a particular aperture.

<FIG> depicts an exemplary aspect of a manufacturing tool <NUM>, in accordance with aspects of the claimed invention. <FIG> is based, in part, on the manufacturing tool <NUM> as depicted in <FIG> discussed hereinabove. However, the refined vacuum tool <NUM> and the ultrasonic welder <NUM> are actuated in one or more directions relative to the distributed vacuum tool <NUM> portion. The independent actuation of one or more portions of the manufacturing tool <NUM> allows for the manufacturing tool <NUM> to be dynamic and versatile in response to different manufacturing operations. For example, the distal end <NUM> of the ultrasonic welder <NUM> may be raised from an initial plane <NUM> that may interfere with the exterior surface <NUM> of the distributed vacuum tool <NUM> contacting a part. The distal end <NUM> may be raised by an actuator <NUM> to a second plane <NUM> that reduces a possibility of interference by the distal end <NUM> with a part by the exterior surface <NUM> of the distributed vacuum tool <NUM>. As depicted in <FIG>, the ultrasonic tool <NUM> and the refined vacuum tool <NUM> are able to move in concert with each other based on a common actuator (e.g., pneumatic cylinder, electro mechanical actuator, hydraulic cylinder, and the like). However, it is also contemplated that the ultrasonic welder <NUM> may be actuated independently of the refined vacuum tool <NUM>.

The actuation of one or more portions of the manufacturing tool <NUM>, such as an ultrasonic welder and/or a refined vacuum tool may be accomplished with a computer-controlled process. For example, it is contemplated that a CNC-type environment controls the position of the one or more portions of the manufacturing tool in response to a particular activity being performed (e.g., part manipulation). The actuation may be controlled by one or more electrical signals, valves, and other variable controls that are functional for allowing the one or more portions of the manufacturing tool to raise, tilt, rotate, or otherwise move relative to one or more other portions of the manufacturing tool.
