An adjustment control device for precise measurement according to an embodiment of the present invention is a product that enables precise measurement by precisely controlling an inspection equipment1such as a vision device for inspecting an inspected object2.

At this time, the inspected object2may be a camera module or other various semiconductor chips, but it is revealed that the type of the inspected object2is not limited in the adjustment control device for precise measurement according to an embodiment of the present invention.

In addition, the inspection equipment1may be a measuring device for measuring the horizontality of the inspected object2, or a vision device for detecting foreign substances buried in the inspected object2, but according to an embodiment of the present invention it is revealed that the type of inspection equipment1in the adjustment control device for precise measurement is not limited.

when the inspection equipment1is a measuring device that measures the horizontality of the inspected object2, the horizontality of the inspected object2is measured by measuring the time for the laser to return after irradiating a laser to the inspected object2.

An adjustment control device for precise measurement according to an embodiment of the present invention may include at least one or more of a lowering control unit10, a rotation control unit20, a tilting type forward and backward control unit30, a rotating control unit40, and horizontal movement control unit50, and a forward and backward control unit60.

An adjustment control device for precise measurement according to an embodiment of the present invention is applied in multiple numbers so that a plurality of inspected objects2can be simultaneously inspected, and is installed on a fixed object7formed in a substantially ‘⊏’ cross-sectional shape at regular intervals.

Then, the inspected object2is seated on the jig9disposed on the upper surface of the inspection table8, and the inspection equipment1performs the inspection on the upper side of the inspected object2.

The lowering control unit10is configured to lower the inspection equipment1with respect to the inspected object2.

To this end, the lowering control unit10may include an elevation means11, a lowering actuation unit12, and a first holding unit13.

The elevation means11includes an elevation member111and an elevation guide member112.

The elevation member111is secured to the bracket3to which the inspection equipment1is secured.

The inspection equipment1may be secured to the front of the bracket3, and the elevation member111may be secured to the rear of the bracket3.

The elevation guide member112guides the elevation of the elevation member111.

To this end, at least one of rail grooves111band112aand slide bars111cand112bfor guiding elevation may be formed in the elevation member111and the elevation guide member112, respectively.

As shown inFIG.2, a slide bar111cand a rail groove111bare formed on one surface of the elevation member111along the longitudinal direction.

In addition, a plurality of slide bars111care applied and arranged to be spaced apart from each other, and rail grooves111bare formed between the slide bars111c.

In addition, the elevation guide member112has a slide bar112band a rail groove112aformed along a longitudinal direction on a surface facing the elevation member111.

A plurality of slide bars112bof the elevation guide member112are applied and arranged to be spaced apart from each other, and rail grooves112aare arranged between the slide bars112b.

The slide bar111cof the elevation member111is inserted into the rail groove112aof the elevation guide member112, respectively, and the slide bar112bof the elevation guide member112is inserted into the rail groove111bof the elevation member111, respectively.

Accordingly, the elevation member111and the slide bar112bof the elevation guide member112are engaged with each other.

In this state, the elevation member111may be raised or lowered vertically while being guided by the slide bars111cand112band the rail grooves111band112a.

A lowering push piece111ahaving a substantially ‘L’ cross-sectional shape is formed on one side of the elevation guide member112.

The lowering control unit12is configured to lower the elevation member111by pushing the lowering push piece111a.

The lowering control unit12is secured to one side of the elevation member111.

The lowering control unit12pushes the lowering push piece111awhile its length is variable to lower the inspection equipment1to the inspected object2.

The lowering control unit12has a hollow cylindrical structure with upper and lower surfaces open and an empty space formed therein so that its length can be varied.

And, a spiral is formed on the inner periphery of the lowering control unit12.

The lowering control unit12may include the rotating handle121that moves up and down along the spiral and a push pin122coupled to the rotating handle121.

Although not shown in the drawing, a spiral fastened to the spiral of the lowering control unit12is formed in a certain region of the outer periphery of the rotating handle121.

Accordingly, the rotating handle121is moved up and down in a form in which the push pin122approaches or moves away from the lowering control unit12according to forward or backward rotation.

As a result, the push pin122is raised or lowered corresponding to the direction of rotation of the rotating handle121.

When the push pin122is raised, which presses the lowering push piece111a, and as a result, the lowering operation unit12is pushed downward and lowered.

As a result, the elevation member111, the bracket3to which the elevation member111is coupled, and the inspection equipment1secured to the bracket3are uniformly lowered. Therefore, it is possible to bring the inspection equipment1closer to the inspected object2.

In addition, when the inspection equipment1is to be spaced apart from the inspected object2, the operator directly grabs the inspection equipment1or the elevation member111and lifts it.

The first holding portion13holds the elevation member111whose height has been adjusted to prevent it from being raised or lowered.

To this end, the first holding portion13may include a first coupling member131, a first holding member132and a first guide member133.

The first coupling member131is secured to the elevation member111and includes a contact region131acontacting the elevation guide member112.

And, the contact region has a spiral hole for holding.

The first holding member132may have a bolt structure.

The first holding member132is fastened to the spiral hole of the first coupling member131and presses the outer surface of the elevation guide member112to secure the elevation member111whose height has been adjusted.

And, the height of the inspection equipment1is changed as necessary, by rotating the first holding member132in one direction to separate it from the elevation guide member, and then after changing the height of the elevation member111to a desired position through the lowering control unit12, rotating again the first holding member132in the other member to press the elevation guide member112, and holding the elevation member111whose height is adjusted.

The first guide member133is coupled to the elevation guide member112.

The first guide member133is secured at a predetermined distance from the elevation guide member112through bolts or pieces.

The first guide member133has a movement guide long hole133afor guiding the movement of the first holding member132.

That is, when the elevation member111is elevated, the first holding member131is elevated along the movement guide long hole133a.

The distance between the inspection equipment1and the inspected object2can be freely and selectively adjusted according to various conditions or conditions such as the characteristics or types of the inspection equipment1by the lowering control unit10.

At this time, the lowering actuation unit12is not limited to the above-described configuration, and can be applied to any one selected from various other configurations or various methods in which the push pin122can be raised or lowered according to the rotation direction of the rotating handle121.

At this time, the lowering distance of the inspection equipment1can be precisely adjusted according to the rotation angle and number of revolutions of the rotating handle. That is, since the lowering operation of the inspection equipment1is proportional to the rising length of the push pin122, the rotating handle may be gradually rotated to adjust the distance between the inspection equipment1and the inspected object2.

Additionally, although not shown in the drawings, at least one of the elevation member111and the elevation guide member112may provide a stopper (not shown) which prevents the elevation member11from lowering due to its own weight and the weight of the inspection equipment1.

The stopper may be formed in the form of any one of a spring, a rack, and a wedge, and keeps the elevation member111stationary in normal times, but only when the push pin122presses the lowering push piece111a. While allowing the elevation member111to lower, when the operator raises the inspection equipment1or the elevation member111, the elevation of the elevation member111may be allowed.

These stoppers can be applied with any one of a variety of commercially available products.

On the other hand, the rotation control unit20is a configuration that controls the lowering control unit10so that the inspection equipment1can be rotated at a predetermined angle in the left and right directions when viewed from a frontal point of view. That is, the rotation control unit is configured to move the inspection equipment1in a kind of swing motion.

On the other hand, the rotation control unit20is a configuration that controls the lowering control unit10so that the inspection equipment1can be rotated at a predetermined angle in the left and right directions when viewed from a frontal point of view. That is, the rotation control unit is configured to move the inspection equipment1in a kind of swing motion.

To this end, the rotation control unit20may include a rotation body21, a rotation operation piece22, a housing and a rotation actuation unit24.

The rotation body21is coupled to one surface of the elevation guide member112constituting the lowering control unit10.

The rotation body21may be coupled to the elevation guide member112by pin or bolting coupling.

The rotation body21is formed in a substantially circular block shape to rotate clockwise or counterclockwise in the inner space of the rotation guide housing (23).

Due to the rotation body21, when viewed from the front, the lowering control unit10can be rotated in the left and right directions.

The rotation operation piece22is coupled to the center portion of the bottom surface of the rotation body21. The rotation operation piece22is provided to rotate the rotation body21in left and right directions, and its operation is controlled by a rotation actuation unit24to be described later.

The rotation guide housing23has a rotation guide groove in which the rotation body21is accommodated.

The rotation guide groove is formed in the same circular shape as the rotation body21.

Therefore, the rotation body21can be rotated in the left and right directions while being accommodated and supported in the rotation guide groove.

A rotation long hole23athrough which the rotation operation piece22passes is formed on the bottom surface of the rotation guide housing23, that is, the bottom surface of the rotation guide groove, in a form connected to the rotation guide groove.

That is, a certain area of the rotation operation piece22is accommodated in the rotation long hole23a, and its below area is protruded downward from the rotation guide housing23.

The rotation operation piece22can be moved in the form of drawing a curve in the left and right directions in this state, and one side and the other side thereof are caught on one end wall or the other end wall of the rotation long hole23aaccording to the moving distance.

A horizontal rotation distance of the rotation operation piece22can be limitedly allowed by the rotation long hole23a.

The rotation actuation unit24is configured to move the rotation operation piece22in a leftward or rightward direction based onFIG.3.

To this end, the rotation actuation units24are formed of a pair of two and coupled to the bottom surface of the rotation guide housing23, and facing each other with the rotation operation piece22interposed therebetween.

Since the configuration of the rotation actuation unit24is the same as that of the lowering actuation unit12described above, a detailed description thereof will be omitted.

By pushing the rotation operation piece22by the rotation actuation unit24, the rotation body21can be rotated at a predetermined angle in the left or right direction. Due to this, the left and right angles of the inspection equipment1can be adjusted.

This will be described in detail with reference toFIGS.1to4.

For example, in the state shown inFIG.1, the inspection equipment1inspects an approximate central region of the upper surface of the inspected object2.

In addition, in the case of inspecting the right area of the inspected object2, the rotating handle of the rotation actuation unit24located on the left side is rotated in the forward direction so that the push pin pushes the rotation operation piece22, and at the same time, the rotating handle of the rotation actuation unit24located on the right side may be rotated in the opposite direction so that the push pin is apart from the rotation operation piece22.

When the rotation operation piece22is pushed by the push pin by manipulating the rotating handle located on the left side, the rotation body21is rotated by a predetermined angle counterclockwise in the rotation guide groove.

As a result, the elevation guide member112coupled to the rotation body21, the elevation member111engaged with the elevation guide member112through the slide bar, and the bracket3to which the elevation member111is coupled, and the inspection equipment1secured to the bracket3is rotated at a predetermined angle in the right direction.

At this time, when the inspection equipment1is rotated by the rotation actuation unit24, a kind of swing motion is performed with the rotation body21as an axis.

Therefore, the inspection equipment1is directed to the right area of the upper surface of the inspected object2, so that the inspection of the right area of the inspected object2can be performed.

Conversely, when inspecting the left area of the inspected object2, the rotating handle of the rotation actuation unit24located on the right side is rotated in the forward direction so that the push pin pushes the rotation operation piece22, at the same time, the rotating handle of the rotation actuation unit24located on the left side may be rotated in the opposite direction so that the push pin is away from the rotation operation piece22.

When the rotation operation piece22is pushed by the push pin by manipulating the rotating handle located on the right side, the rotation body21is rotated clockwise by a predetermined angle in the rotation guide groove.

As a result, the elevation guide member112coupled to the rotation body21, the elevation member111engaged with the elevation guide member112through the slide bar, and the bracket3to which the elevation member111is coupled, and the inspection equipment1fixed to the bracket3are rotated at a predetermined angle in the left direction.

Therefore, the inspection equipment1is directed to the right area of the upper surface of the inspected object2, so that the inspection of the left area of the inspected object2can be performed.

At this time, the rotation angle of the inspection equipment1may be adjusted according to the rotation direction, rotation angle, and number of rotations of the rotating handle. That is, since the rotation of the inspection equipment1is proportional to the moving distance of the rotation operation piece22pushed to the push pin, When the left side of the rotation operation piece22is pushed by gradually rotating the rotating handle located on the left side, the inspection equipment1is gradually rotated in the right direction, and when the rotating handle located on the right is gradually rotated to push the right side of the rotation operation piece22, the inspection equipment1is gradually rotated in the left direction. As a result, the inspection equipment1can inspect all areas from the left end to the right end of the object to be inspected object2by adjusting the rotation direction, rotation angle, and number of rotations of the rotating handle.

On the other hand, the tilting type forward and backward control unit30is disposed above the rotation control unit20, and is configured to control the rotation control unit20so that the inspection equipment1moves forward and backward while being tilted in forward or backward directions on the inspected object2.

To this end, the tilting type forward and backward control unit30may include a slide unit31, a forward and backward guide32, and an additional forward and backward actuation unit62.

A plurality of slide units31are applied and mounted on the coupling plate4coupled to the upper surface of the rotation control unit20to be spaced apart from each other at a predetermined interval.

The slide units31operate integrally with each other due to being coupled to the coupling plate4.

At both edges of the upper surface of the slide unit31, a first curved surface portion31ahaving a structure in which the center area is depressed downward, and the front and rear sides of the center area are inclined upward, respectively, is formed.

Further, in the center of the upper surface of the slide unit31, a curved rail portion31bhaving a structure in which the center part is depressed downward and the front and rear sides of the center area are inclined upward, respectively, is protruded.

At this time, the above-described first curved surface portion31ais formed on both sides of the curved rail portion.

A separation prevention bracket31cis formed on one side of the slide unit31to prevent separation from the forward and backward guides32.

A certain area of the separation prevention bracket31cprotrudes upward to the first curved surface portion31a.

A curved horizontal long hole31dthat substantially prevents the forward and backward guides32from separating is formed in the protruding area of the separation prevention bracket31c.

The forward and backward guides32guide the sliding to the slide unit31, respectively, and are seated on the upper surface of the first curved surface portion31aon both sides of the bottom surface and the second curved surface portion32ahaving the same curvature as the first curved surface portion31aprotrudes downward.

In addition, the forward and backward guide32has an accommodating groove32bin which the curved rail member31bis accommodated between the second curved surface portion32a.

In addition, a forward and backward push piece32cis formed on one side of the forward and backward guide32to be pushed by the additional forward and backward actuation unit62.

And, on the other side of the forward and backward guide32, a separation prevention pin32dis formed to move along the curved horizontal long hole31d.

The additional forward and backward actuation unit62moves the slide unit31forward or backward, and when it moves forward or backward, returns it to its original position.

The drawing shows an example in which three slide unit31and forward and backward guides32are applied, respectively, and the slide unit31are installed on one coupling plate4and can be driven integrally. As shown, even if only two of the additional forward and backward operation units62are applied, the three slide units31can be uniformly moved forward or backward.

The additional forward and backward actuation unit62is fixed to one side of any two slide units31among the three slide units31, respectively, as shown inFIGS.8and9, respectively.

At this time, the first additional forward and backward actuation unit33ais coupled to move the slide unit31forward, and the second additional forward and backward actuation unit33bis coupled to relatively move the slide unit31backward.

Since the configuration of the additional forward and backward actuation unit62is the same as that of the lowering actuation unit12and the rotation operation unit24, a detailed description thereof will be omitted.

By pushing each of the forward and backward push pieces32cthrough the additional forward and backward actuation units33aand33b, the inspection equipment1can be moved forward or backward from the top of the inspected object2.

Next, an operation example of the tilting type forward and backward control unit30described above will be described.

For example, in the state shown inFIG.1, the inspection equipment1inspects an approximate central region of the upper surface of the inspected object.

In addition, when inspecting the front region of the inspected object2, the rotating handle of the first additional forward and backward actuation unit33ais rotated in the forward direction so that the push pin pushes the forward and backward push piece32c, at the same time, the rotating handle of the second additional forward and backward actuation unit33bis rotated in the opposite direction so that the push pin is apart from the other forward and backward push pieces32c.

Due to this, the slide unit31slides in the forward direction in the forward and backward guide32, and in this process, the first curved surface portion31amoves along the second curved surface portion32a, as a result, the inspection equipment1moves forward while being tilted at a predetermined angle.

At this time, the inspection equipment1inspects a certain area on the front side of the inspected object2in a state where the lower side is tilted toward the front of the central region of the inspected object2and the upper side is tilted toward the rear of the central region of the inspected object2.

Contrary to this, when inspecting the rear area of the inspected object2, the rotating handle of the first additional forward and backward actuation unit33ais rotated in the backward direction so that the push pin moves away from the forward and backward push piece32c. At the same time, the rotating handle of the second additional forward and backward actuation unit33bis rotated in the forward direction so that the push pin pushes the other forward and backward push piece32c.

Due to this, the slide unit31slides in the backward direction in the forward and backward guide32, and in this process, the first curved surface portion31arides on the second curved surface portion32aas a result, the inspection equipment1moves backward while being tilted.

At this time, the inspection equipment1inspects a certain area on the rear side of the inspected object2in a state where the lower side is tilted toward the rear of the central region of the inspected object2and the upper side is tilted toward the front of the central region of the inspected object2.

At this time, forward and backward distances and tilting angles of the inspection equipment1may be adjusted according to the rotation direction, rotation angle, and number of rotations of the rotating handle. That is, the forward, backward and tilting of the inspection equipment1is proportional to the moving distance of the forward and backward push piece32cpushed on the push pin, so that the rotating handle of the first additional forward and backward actuation unit33ais gradually rotated to push the forward and backward push piece32cso that the inspection equipment1is gradually moved forward and tilted. When the rotating handle of the second additional forward and backward actuation unit33bis gradually rotated to push the forward and backward push piece32cin the opposite direction so that the inspection equipment1gradually moves backward and is tilted. As a result, the inspection equipment1can inspect all areas from the front end to the rear end of the inspected object while maintaining a certain inclination angle by adjusting the rotation direction, rotation angle, and number of rotations of the rotating handle.

On the other hand, the rotating control unit40is configured to control the additional forward and backward drive unit so that the inspection equipment1can be selectively rotated in place at a predetermined angle in a clockwise or counterclockwise direction when viewed from a planar perspective.

To this end, the rotating control unit40may include a rotating body41, a rotating operation piece42, a rotating guide housing43, and a rotating actuation unit44.

The rotating body41is coupled to the upper surface of the first additional coupling plate5coupled to the upper surface of the forward and backward guides32.

The rotating body41may be coupled to the first additional coupling plate5by pin or bolting coupling.

The rotating body41may be formed in a substantially circular block shape and rotate clockwise or counterclockwise in the inner space of the rotating guide housing43.

When viewed from the frontal point of view, it is possible to rotate the additional forward and backward driving unit in the left and right directions due to the rotating body41.

When the additional forward and backward driving unit is rotated in the left and right directions, the rotation control unit20, the lowering control unit10, the bracket, and the inspection equipment1are rotated in the left and right directions at the same time.

The rotating operation piece42is coupled to one end of the rotating body41. The rotating operation piece42is provided to rotate the rotating body41in left and right directions, and its operation is controlled by a rotation actuation unit44to be described later.

The rotating guide housing43has a rotating guide groove in which the rotating body41is accommodated.

The rotating guide groove is formed in the same circular shape as the rotating body41.

Therefore, the rotating body41can be rotated in the left and right directions while being accommodated in the rotating guide groove.

On one side of the rotating guide housing43, a rotating long hole43athrough which the rotating operation piece42passes is formed in a form connected to the rotating guide groove.

That is, a certain area of the rotating operation piece42is accommodated in the rotating long hole43a, and a certain area protrudes out of the rotating guide housing.

In this state, the rotating operation piece42can be moved in the form of drawing a curve in the left and right directions, and one side and the other side thereof are caught on one end wall or the other end wall of the rotating long hole43aaccording to the moving distance.

A horizontal rotational distance of the rotating operation piece42may be limitedly allowed through the rotating long hole43a.

The rotating actuation unit44is configured to move the rotating operation piece42in a leftward or rightward direction based onFIG.6.

To this end, the rotating actuation units44are composed of a pair of two, so that they are coupled to one surface of the rotation guide housing43, and face each other with the rotating operation piece42interposed therebetween.

Since the configuration of the rotating actuation unit44is the same as that of the aforementioned rotation actuation unit24, a detailed description thereof will be omitted.

By pushing the rotating operation piece42through the rotating actuation unit44, the rotating body41can be rotated at a predetermined angle in the left or right direction. Due to this, the angle can be adjusted by adjusting the inspection equipment1clockwise or counterclockwise.

This will be described in detail with reference toFIGS.1,6and7.

For example, in the state shown inFIG.1, the inspection equipment1inspects an approximate central region of the upper surface of the inspected object2.

In such a state, a situation in which the inspection unit must be rotated in place at a predetermined angle may occur due to the type, size, shape, and other various reasons of the inspected object2.

That is, the rotating control unit40can be used only in the above-mentioned special situation.

When it is desired to rotate the inspection equipment1in the right direction by a predetermined angle, the rotating handle of the rotating actuation unit44located on the left side is rotated in the forward direction so that the push pin pushes the rotating operation piece42, at the same time, the rotating handle of the rotating actuation unit44located on the right side may be rotated in the backward direction so that the push pin is apart from the rotating operation piece42.

When the rotating operation piece42is pushed by the push pin by manipulating the rotating handle located on the left side, the rotating body41is rotated by a predetermined angle counterclockwise in the rotating guide groove.

As a result, the first additional coupling plate5coupled to the rotating body41, the tilting type forward and backward driving unit, the rotation control unit20, the lowering control unit10, the bracket3and the inspection equipment1are rotated counterclockwise by a predetermined angle.

On the contrary, when it is desired to rotate the inspection equipment1in the left direction by a predetermined angle, the rotating handle of the rotating actuation unit44located on the right side is rotated in the forward direction so that the push pin pushes the rotating operation piece22, at the same time, by rotating the rotating handle of the rotating actuation unit44located on the left side in the backward direction, the push pin may move away from the rotating operation piece42.

When the rotating operation piece42is pushed by the push pin by manipulating the rotating handle located on the right side, the rotating body41is rotated clockwise by a predetermined angle in the rotating guide groove.

As a result, the first additional coupling plate5coupled to the rotating body41, the tilting type forward and backward drive unit, the rotation control unit20, the lowering control unit10, the bracket3and the inspection equipment1are rotated clockwise by a predetermined angle.

Through the rotating control unit40, the inspected object2can be inspected in various ways while selectively and freely rotating the inspection equipment1in a clockwise or counterclockwise direction as needed.

Meanwhile, the horizontal movement control unit50controls the rotating control unit40to horizontally move the inspection equipment1disposed above the inspected object2in left and right directions.

To this end, the horizontal movement control unit50may include a horizontal movement means51, a movement actuation unit52, and a second holding portion53.

The horizontal movement means51may include a horizontal movement member511secured to the upper surface of the second additional coupling plate6secured to the upper surface of the rotating guide housing43and a horizontal movement guide member512for guiding the movement of the horizontal movement member511and having a movement push piece513on one side.

In addition, at least one of rail grooves511band512band slide bars511aand512afor guiding movement may be formed in the horizontal movement member511and the horizontal movement guide member512, respectively.

As shown inFIGS.8and9, a slide bar511aand a rail groove511bare formed on the upper surface of the horizontal movement member511along the longitudinal direction.

In addition, a plurality of slide bars511aare applied and arranged to be spaced apart from each other, and rail grooves511bare formed between the slide bars511a.

In addition, a slide bar512aand a rail groove512bare formed on the bottom surface of the horizontal movement guide member512along the longitudinal direction.

A plurality of slide bars512aof the horizontal movement guide member512are applied and arranged to be spaced apart from each other, and rail grooves512bare arranged between the slide bars512a.

The slide bar512aof the horizontal movement guide member512is inserted into the rail groove511bof the horizontal movement member511, respectively, and the slide bar511aof the horizontal movement member511is inserted into the rail grooves512bof the horizontal movement guide member512, respectively.

Accordingly, the horizontal movement member511and the horizontal movement guide member512are engaged with each other.

In this state, the horizontal moving member511is guided to the slide bars511aand512aand the rail grooves511band512band can be moved in both directions in the horizontal direction.

The movement actuation unit52is configured to move the horizontal movement member511in both directions in the horizontal direction.

The movement actuation unit52is fixed to one side of the horizontal movement member511.

Since the configuration of the movement actuation unit52is the same as that of the aforementioned control units, a detailed description thereof will be omitted.

Through such a movement actuation unit52, the inspection equipment1can be moved in the horizontal direction, that is, along the left and right width directions of the inspected object2.

This will be described in detail with reference toFIGS.1,8and9.

For example, in the state shown inFIG.1, the inspection equipment1inspects an approximate central region of the upper surface of the inspected object2.

And, when inspecting the right area of the inspected object2, the rotating handle is rotated in one direction. When the rotating handle is rotated, the push pin moves forward and the movement push piece513is pushed.

In this way, when the push pin pushes the movement push piece513, the horizontal movement member511slides to the right, and eventually the inspection equipment1moves to the right.

Therefore, the right side of the inspected object2can be inspected by the inspection equipment1.

At this time, the horizontal movement distance of the inspection equipment1may be adjusted according to the rotation angle and the number of rotations of the rotating handle constituting the horizontal movement actuation unit50. That is, since the rightward movement of the inspection equipment1is proportional to the forward length of the push pin pushing the movement push piece513, when the movement push piece513is pushed by gradually rotating the rotating handle, the inspection equipment1is gradually moved to the right. As a result, the inspection equipment1can inspect all areas from the center to the right end of the inspected object2by adjusting the rotation angle and the number of rotations of the rotating handle.

And, in the case of inspecting the left area of the inspected object2, the operator can directly push the inspection equipment1to the left side to inspect it.

The second holding portion53is configured to hold the horizontal movement member511for which horizontal positioning has been completed so as not to move.

To this end, the second holding portion53may include a second fastening member531, a second holding member532, and a second guide member533.

The second fastening member531is secured to the horizontal movement member511and includes a contact region531acontacting the horizontal movement guide member.

Also, a spiral hole for holding is formed in the contact region531a.

The second holding member532may have a bolt structure.

The second holding member532presses the outer surface of the horizontal movement guide member while being fastened to the spiral hole of the second fastening member531to fix the horizontal movement member511whose location has been moved in the horizontal direction.

And, when changing the left and right positions of the inspection equipment1as needed, rotate the second holding member532in one direction to separate it from the horizontal guide member512, and then after changing the position of the horizontally movement member511to a desired position through the movement actuation unit52, by rotating again the second holding member532in the other direction to press the horizontal movement guide member512, the horizontally movement member511whose position is changed is held.

The second guide member533is coupled on the horizontal movement guide member512.

The second guide member533is secured at a predetermined distance from the horizontal movement guide member512through bolts or pieces.

A movement guide long hole533afor guiding the movement of the second holding member532is formed in the second guide member533.

That is, when the horizontal movement member511is moved, the second holding member532is moved along the movement guide long hole533a.

Although not shown in the drawings, the second holding portion may be omitted. In this case, an example in which the movement actuation unit52is coupled to the right side of the horizontal movement member511is shown inFIG.8, and if another movement control unit (not shown) having a structure capable of moving the horizontal movement member511in the left direction and a moving push piece513are added to the left side of the horizontal movement member511, the inspection equipment1will be able to be easily moved along the left and right width directions of the inspected object2.

However, if the movement actuation unit52and the movement push piece513are provided on the front and rear surfaces of the horizontal movement member511, respectively, another movement actuation unit52may come into contact with the movement push piece513to limit its movement distance in the process of moving the inspection equipment1to the left or right.

To prevent this, it is preferable to detachably couple the movement control unit52and the movement push piece513through bolts or the like.

On the other hand, the forward and backward control unit60is configured to transmit a moving force to the rotation control unit20so that the inspection equipment1can be moved forward or backward on the inspected object2.

To this end, the forward and backward control unit60may include a forward and backward movement means61, a forward and backward actuation unit62, and a third holding portion63.

The forward and backward movement means61may include a forward and backward movement member611coupled to the upper surface of the horizontal movement guide member512, and a forward and backward movement guide member612which guides a forward and backward movement of the forward and backward movement member611in a state that it is secured to the fixed object7and has a forward and backward push piece613on one side.

In addition, at least one or more of rail grooves611aand612aand slide bars611band612bfor guiding movement are formed in the forward and backward movement member611and the forward and backward movement guide member612, respectively.

As shown inFIGS.8and9, a slide bar611band a rail groove611aare formed on the upper surface of the forward and backward movement member611along the longitudinal direction.

In addition, a plurality of slide bars61bare applied and arranged to be spaced apart from each other, and rail grooves611aare formed between the slide bars611b.

In addition, a slide bar612band a rail groove612aare formed on the bottom surface of the forward and backward movement guide member612along the longitudinal direction.

A plurality of slide bars612bof the forward and backward movement guide member612are applied and arranged to be spaced apart from each other, and rail grooves612aare arranged between the slide bars612b.

The slide bar612bof the forward and backward movement guide member612is inserted into the rail groove611aof the forward and backward movement member611, respectively, and the slide bar61bof the forward and backward movement member611is inserted into the rail grooves612aof the forward and backward movement guide members612, respectively.

Thus, the horizontal movement member511and the horizontal movement guide member512are engaged with each other.

In this state, the forward and backward movement member611can be moved forward and backward while being guided to the slide bars611band612band the rail grooves611aand612a.

The forward and backward actuation unit62moves the forward and backward movement member611forward or backward.

The forward and backward actuation unit62is secured to one side of the forward and backward movement member611.

Since the configuration of the forward and backward actuation unit62is the same as that of the aforementioned operation units, a detailed description thereof will be omitted.

The inspection equipment1can be moved in the forward and backward directions of the inspected object2by the forward and backward actuation unit62.

This will be described in detail with reference toFIGS.1,8and9.

For example, in the state shown inFIG.1, the inspection equipment1inspects an approximate central region of the upper surface of the inspected object2.

And, when it is desired to inspect the rear area of the inspected object2, the rotating handle is rotated in one direction. When the rotating handle is rotated, the push pin moves forward and pushes the forward and backward push pieces613.

In this way, when the push pin pushes the forward and backward push piece613, the forward and backward movement member611slides rearward, and eventually the inspection equipment1moves backward.

Therefore, it is possible to inspect from the central part to the rear part of the inspected object2with the inspection equipment1.

At this time, the backward movement distance of the inspection equipment1may be adjusted according to the rotation angle and the number of rotations of the rotating handle constituting the forward and backward actuation unit60. That is, since the movement of the inspection equipment1in the backward direction is proportional to the forward length of the push pin that pushes the forward and backward push pieces613, when the rotating handle is gradually rotated to push the forward and backward push pieces613, the inspection equipment1is gradually reversed. As a result, the inspection equipment1can inspect all areas from the center to the rear end of the inspected object2by adjusting the rotation angle and the number of rotations of the rotating handle.

And, in the case of inspecting the front area of the inspected object2, the operator can directly push the inspection equipment1forward and inspect it.

The third holding portion63is configured to hold the forward and backward movement member so as not to move after completing position control in the forward and backward direction.

To this end, the third holding portion63may include a third coupling member631, a third holding member632and a third guide member633.

The third coupling member631is fixed to the forward and backward movement member611and includes a contact region633acontacting the forward and backward movement guide member.

And, a spiral hole for holding is formed in the contact region633a.

The third holding member632may have a bolt structure.

The third holding member632presses the outer surface of the forward and backward movement guide member612while being fastened to the spiral hole of the third coupling member631so that the forward or backward movement member611whose position movement is completed is secured.

And, in a case of changing the forward and backward position of the inspection equipment1as needed, the third holding member632is rotated in one direction to is separated it from the forward and backward movement guide member612, and then after changing the position of the forward and backward movement member611by the forward and backward actuation unit62to a desired position, the third holding member632is rotated again in the other direction to press the forward and backward movement guide member612, thereby, the forward and backward movement member611whose position has been changed is held.

The third guide member633is coupled to the forward and backward movement guide member612.

The third guide member633is secured at a predetermined distance from the forward and backward movement guide member612through bolts or pieces.

A movement guide long hole633afor guiding movement of the third holding member632is formed in the third guide member633.

That is, when the forward and backward movement member611moves, the third holding member632moves along the movement guide long hole633a.

Although not shown in the drawings, the third holding portion may be omitted. And, since an example in which the forward and backward actuation unit62is coupled to the front of the forward and backward movement member611is depicted in the drawing, if another forward and backward actuation unit having a structure that can move the forward and backward movement member611forward (not shown) and the forward and backward push piece (not shown) are added to the rear surface of the forward and backward movement member611, the inspection equipment1can be easily moved in the front and rear directions of the inspected object2.

However, if the forward and backward actuation unit62and the forward and backward push pieces are provided on the left and right sides of the forward and backward movement guide member612, respectively, another forward and backward actuation unit62may come into contact with the forward and backward push piece in the process that the inspection equipment1moves forward or backward by any one forward and backward actuation unit62, so that the moving distance may be limited.

In order to prevent this, it is preferable to detachably couple the forward and backward actuation unit62and the forward and backward push piece through bolts or the like.

An adjustment control device for precise measurement according to an embodiment of the present invention can measure the horizontality of a various part of the inspected object2and perform a vision test while moving the inspection equipment1on the inspected object to a various position or adjusting the space of the inspection equipment1with respect to the inspected object2by the above-described lowering control unit10, rotation control unit20, tilting type forward and backward control unit30, rotating control unit40, the horizontal movement control unit50, and the forward and backward control unit60.

In addition, in the adjustment control device for precise measurement according to an embodiment of the present invention, it is revealed that all components of the lowering control unit10, the rotation control unit20, the tilting type forward and backward control unit30, the rotating control unit40, and the horizontal movement control unit50and the forward and backward control unit60or like are not essentially used when measuring the horizontality of the inspected object2or inspecting the vision.

That is, the operator can selectively control at least one configuration to measure the horizontality or inspect the vision for various reasons such as the shape characteristics of the inspected object2or measurement conditions.
