Description:
FIELD 
     The present disclosure relates generally to disassembly of devices, and more particularly to a fixture, apparatus, and method configured to disassemble an electronic device. 
     BACKGROUND 
     Electronic devices often include multiple portions that are coupled together during assembly thereof. Such assembly may include certain fastening methods and mechanisms that may not be easily reversible. Accordingly, such devices may not be configured for disassembly using conventional techniques and methods. 
     For example, certain electronic devices may include a first separable portion and a second separable portion that may be bonded or adhered together. By way of further example, an electronic device may include a cover panel (e.g., cover glass) adhered to a housing via pressure sensitive adhesive. Further, the configuration of the engagement between the cover panel and the housing may make it difficult to pry apart or otherwise separate the housing from the cover panel using conventional tools. 
     Such disassembly may be desirable in that it may allow for repair of the electronic device. Alternatively, disassembly may allow for removal and reuse of components of the electronic device in other electronic devices. Accordingly, despite challenges associated with disassembly, such disassembly may be desirable. 
     Accordingly, the present disclosure is directed to fixtures, apparatuses, and methods configured to facilitate disassembly of devices such as electronic devices. 
     SUMMARY 
     A disassembly apparatus may include first and second disassembly fixtures which are configured to respectively engage first and second separable portions of an electronic device. For example, the first disassembly fixture may engage a cover panel of the electronic device and the second disassembly fixture may engage a housing of the electronic device. Engagement therebetween may occur via use of suction. In this regard, the first and second disassembly fixtures may include engagement bodies with suction effectors coupled thereto that facilitate engagement with a respective portion of the electronic device. Thereby, when an actuator is actuated to produce a separation force, the separable portions of the electronic device may separate. 
     In certain embodiments the suction effectors may comprise channels in the face of the engagement bodies and a sealing member may extend around the perimeter of the channels such that a large surface area is employed to apply suction to a respective portion of the electronic device. Further, body heaters may heat the engagement bodies to assist in releasing, for example, pressure sensitive adhesive. Localized heaters, positioned at particular locations at which the pressure sensitive adhesive is located, may further assist in loosening the pressure sensitive adhesive by briefly and locally heating the electronic device to a great temperature than the temperature at which the body heater heats the electronic device. Further, use of linear separation of the first and second separable portions may reduce bending of the cover panel, which could damage the cover panel and/or other components. 
     Other apparatuses, methods, features and advantages of the disclosure will be or will become apparent to one with skill in the art upon examination of the following figures and detailed description. It is intended that all such additional systems, methods, features and advantages be included within this description, be within the scope of the disclosure, and be protected by the accompanying claims.

     DETAILED DESCRIPTION 
     Representative applications of systems, apparatuses, computer program products and methods according to the presently described embodiments are provided in this section. These examples are being provided solely to add context and aid in the understanding of the described embodiments. It will thus be apparent to one skilled in the art that the presently described embodiments can be practiced without some or all of these specific details. In other instances, well known process steps have not been described in detail in order to avoid unnecessarily obscuring the presently described embodiments. Other applications are possible, such that the following examples should not be taken as limiting. 
     As described in detail below, the following relates to disassembly apparatuses, fixtures, computer program products, and methods. Embodiments of the disclosure may be employed to disassemble a variety of devices, and in particular electronic devices such as tablet computing devices, phones, and/or any other device including two or more separable portions. 
     In one embodiment a disassembly apparatus may include first and second disassembly fixtures which are configured to respectively engage first and second separable portions of an electronic device. For example, the first disassembly fixture may engage a cover panel of the electronic device and the second disassembly fixture may engage a housing of the electronic device. Engagement therebetween may occur via use of suction. In this regard, the first and second disassembly fixtures may include engagement bodies with suction effectors coupled thereto that facilitate engagement with a respective portion of the electronic device. Thereby, when an actuator is actuated to produce a separation force therebetween, the separable portions of the electronic device may separate. 
     In certain embodiments the suction effectors may comprise channels in the face of the engagement bodies and a sealing member may extend around the perimeter of the channels such that a large surface area is employed to apply suction to a respective portion of the electronic device. Further, body heaters may heat the engagement bodies to assist in releasing pressure sensitive adhesive. Localized heaters, positioned at particular locations at which the pressure sensitive adhesive is located, may further assist in loosening the pressure sensitive adhesive by briefly and locally heating the electronic device to a great temperature than the temperature at which the body heater heats the electronic device. Thereby, issues with respect to heating the components of the electronic device beyond a temperature at which damage occurs may be avoided. In this regard, for example, magnets may lose magnetism when heated beyond a threshold temperature. 
     These and other embodiments are discussed below with reference to the figures. However, those skilled in the art will readily appreciate that the detailed description given herein with respect to these figures is for explanatory purposes only. 
     Various embodiments of devices, and particularly embodiments of electronic devices including a display may benefit from embodiments of the present disclosure. In this regard,  FIG. 1  illustrates an overhead view of an example embodiment of an electronic device in the form of a tablet computing device  100 . The tablet computing device  100  may include a cover panel  102  and a housing  104  that define at least a portion of an outer surface thereof. 
     The cover panel  102  may comprise glass, plastic, crystal, or any other material configured to allow light to travel therethrough. In this regard, as described hereinafter, a display assembly may be positioned under the cover panel  102  and within the housing  104 . In certain embodiments the cover panel  102  may be configured to receive inputs. For example, the display assembly may cooperate with the cover panel  102  to define a touch screen. 
     The housing  104  may be configured to provide the tablet computing device  100  with structure and support. In this regard, the housing  104  may preferably comprise a relatively rigid member. For example, the housing  104  may comprise a metal such as an aluminum alloy that defines a lightweight, yet rigid structure. However, various other materials including other metals (e.g., titanium, steel), plastic, and glass, etc. may be employed in the housing  104 . 
     As noted above, in some embodiments the tablet computing device  100  may include a touchscreen. In some embodiments various other inputs and/or outputs may be provided. For example, the tablet computing device  100  may include a button  106  in some embodiments. As illustrated, the button  106  may be at least partially surrounded by the cover panel  102  in some embodiments. Various other inputs and/or outputs may be provided, such as a camera, a speaker, an audio port, an electrical port, a data port, etc., which may be provided in any quantity and any location, which may be combined or provided as separate elements. 
       FIG. 2  illustrates a sectional view through the tablet computing device  100 . As illustrated, the cover panel  102  and the housing  104  may define at least part, and in some embodiments substantially all, of the exterior of the tablet computing device  100 . A display assembly  108  may be positioned inside of the cover panel  102  and within the housing  104 . In this regard, the display assembly  108  may be positioned adjacent (e.g., in contact with) the cover panel  102  in order to provide for output of light therethrough and, optionally, to receive inputs through the cover panel in embodiments in which the tablet computing device  100  includes a touchscreen. The display assembly  108  may or may not be affixed to the cover panel  102 . The display assembly  108  can display visual content such as a graphical user interface, still images such as photos as well as video media items such as movies. The display assembly  108  can display images using any appropriate technology such as a liquid crystal display (LCD), a light emitting diode (LED) display, an organic light emitting diode (OLED) display, etc. 
     A plurality of additional electronic components  110  may also be received in the housing  104 . For example, the electronic components  110  may be positioned between the display assembly  108  and the housing  104 . As may be understood, the electronic components  110  may vary depending on the particular functionality of the tablet computing device  100 . However, by way of example, the electronic components  110  may include a battery, a communication interface, an antenna, a processor, memory, etc. 
     The cover panel  102  may be indirectly or directly fastened to the housing  104  so as to retain the tablet computing device  100  in the assembled configuration. In this regard, the cover panel  102  may secured to the housing  104  via a variety of methods and means. For example, interference fit, fasteners, and/or adhesives, etc. may be employed to fasten the cover panel  102  to the housing  104 . 
     In one embodiment, as illustrated in  FIGS. 1 and 2 , a pressure sensitive adhesive  112  may be employed to secure the cover panel  102  to the housing. The pressure sensitive adhesive  112  may comprise a double-sided tape. The pressure sensitive adhesive  112  may evenly extend around the perimeter of the cover panel  102  in some embodiments. In an alternative embodiment the pressure sensitive adhesive  112  may be positioned at limited portions of the perimeter of the cover panel  102 . For example, the pressure sensitive adhesive  112  may be positioned at first and second opposing ends  100 A,  100 B of the tablet computing device  100 . In this regard, in some embodiments, as illustrated in  FIG. 1 , the pressure sensitive material  112  may be positioned at each of a plurality of corners  100 C-F of the tablet computing device  100 . The pressure sensitive material  112  may be disposed in various other configurations, such as along the edges of the cover panel  102  proximate the first and second opposing ends  100 A,  100 B of the tablet computing device  100 . In another embodiment the pressure sensitive material  112  may be disposed around the perimeter of the cover panel  102  with extra pressure sensitive material employed at one or more locations such as at the corners  100 C-F. In this regard, the position of the pressure sensitive material  112  may be selected to define an optimal coupling between the cover panel  102  and the housing  104 . 
     Accordingly, the cover panel  102  may be securely coupled to the housing  104 . Use of pressure sensitive adhesive  112  may be desirable in that it may provide for a secure connection while hiding the securing mechanism from view, which may provide a pleasing exterior appearance. While use of the pressure sensitive adhesive  112  and/or other coupling mechanisms to couple the cover panel  102  to the housing  104  may provide a secure connection therebetween, in certain instances disassembly of the tablet computing device  100  may be desirable. Further, as a result of the cover panel  102  optionally defining a recessed configuration with respect to the housing  104  or otherwise defining a configuration in which edges thereof are substantially inaccessible, it may be difficult to decouple the cover panel from the housing. 
     Accordingly, embodiments of the present disclosure are directed to disassembly apparatuses configured to separate first and second separable portions of devices (e.g., the tablet computing device  100 , or other electronic devices). In this regard,  FIG. 3  schematically illustrates an embodiment of a disassembly apparatus  200  according to an embodiment of the present disclosure. As illustrated, the disassembly apparatus  200  may include a first disassembly fixture  202  and a second disassembly fixture  204 . The first disassembly fixture  202  may be configured to engage a first separable portion of an electronic device (e.g., the cover panel  102  of the tablet computing device  100 ). Similarly, the second disassembly fixture  204  may be configured to engage a second separable portion of the electronic device (e.g., the housing  104  of the tablet computing device  100 ). 
     Depending on the particular construction of the device undergoing disassembly, the first separable portion and the second separable portion may comprise a cover panel and a housing, as described above. Thus, for purposes of brevity, the device undergoing disassembly is generally referred to as the tablet computing device  100  and the first and second separable portions are generally referred to hereinafter as comprising the cover panel  102  and the housing  104 . However, as may be understood, the first and second separable portions may comprise various other components depending on the particular construction of the device undergoing disassembly, and such device may vary. For example, the disassembly apparatuses of the present disclosure may be configured to disassemble any device comprising two or more separable portions. Thus, for example, the disassembly devices of the present disclosure may also be suited to disassembling televisions, monitors, smartphones, laptops, etc. 
     As illustrated in  FIG. 3 , the disassembly apparatus  200  may further comprise an actuator  206  configured to apply a force to separate the cover panel  102  from the housing  104  of the tablet computing device  100 . The actuator  206  may comprise a pneumatic piston, a hydraulic piston, a lever, a robotic arm, or any other embodiment of manual or automated actuator. 
     As illustrated, in some embodiments the disassembly apparatus  200  may be configured to hingedly displace the second disassembly fixture  204  away from the first disassembly fixture  202 . Use of a hinged, or pivoting configuration may be desirable in that it may concentrate force on an edge of the tablet computing device  100  (e.g., proximate one of the first and second opposing ends  100 A,  100 B) such that separation initially starts at this edge and encourages further separation. In this regard, in some embodiments the second disassembly fixture  204  may be coupled to a hinge  208  about which the second disassembly fixture pivots as the actuator  206  applies the force to separate the cover panel  102  from the housing  104 . Alternatively, in embodiments in which the actuator comprises a robotic arm, the robotic arm may be configured to move the second disassembly fixture along a path that mimics the arc associated with hingedly decoupling the housing from the cover panel. However, as will be described below, a hinged decoupling path may not be preferable in some instances. 
     The disassembly apparatus  200  may further comprise a load cell  210  configured to detect a load applied between the cover panel  102  and the housing  104  of the tablet computing device  100 . In this regard, the load cell  210  may be coupled to the actuator  206  or otherwise positioned to detect the load applied between the cover panel  102  and the housing  104 . In one embodiment the load cell  210  may comprise a strain gauge. In some embodiments the load cell  210  may be in communication with a display  212  that outputs an indicator of the load. Alternatively, or additionally, the load cell  210  may be in communication with a controller  214 . The controller  214  may be configured to control the actuator  206  so as to application of the force to separate the cover panel  102  from the housing  104  and perform various other functions as described hereinafter. 
     During movement of the second disassembly fixture  204  away from the first disassembly fixture  202 , it may be desirable to limit the force separating the cover panel  102  from the housing  104  below a threshold force. In this regard, as may be understood, damage may occur to the cover panel  102 , the housing  104 , and/or other components of the tablet computing device  100  in instances in which too much force is applied. Accordingly, the amount of force applied may be limited below a threshold force at which damage occurs, which may be empirically determined in some embodiments. Control in this manner may be conducted manually via an operator monitoring the display  212 , or the controller  214  may direct actuation of the actuator  206  such that the threshold force is not exceeded based on input from the load cell  210 . 
     Similarly, a separation distance between the cover panel  102  and the housing  104  may be limited. In this regard, as the cover panel  102  and the housing  104  separate, it may be necessary to disconnect a cable or other connector extending therebetween, particularly in embodiments in which the display assembly  108  and/or other components are coupled to the cover panel. Thus, for example, a mechanical stop may be employed to limit movement of the second disassembly fixture  204 . 
     However, in some embodiments the second disassembly fixture  204  may be configured to move to a greater separation distance following stopping at the intermediate separation distance. Thereby, for example, the housing  104  may be completely separated from the cover panel  102  following disconnection of the cable or other connector at the intermediate separation distance. In this regard, the controller  214  may be configured to initially stop at the intermediate separation distance and then extend the separation distance thereafter upon operator confirmation that the cable or other connector is disconnected to completely separate the housing  104  from the cover panel  102 , as illustrated in  FIG. 4 . 
     In the example provided above, the second disassembly fixture  204  is generally described as moving and the first disassembly fixture  202  is generally described as being stationary. However, in other embodiments the first disassembly fixture could move and the second disassembly fixture could be stationary, or both the first disassembly fixture and the second disassembly fixture could move. In this regard, relative movement between the first disassembly fixture and the second disassembly fixture could occur in a variety of manners. 
     In order to facilitate separation in the manner described above, the first and second disassembly fixtures  202 ,  204  may comprise certain features. In this regard, the first disassembly fixture  202  and the second disassembly fixture  204  may employ one or more of various techniques to grasp the cover panel  102  and the housing  104 . For example, mechanical grippers may be configured to grasp one or both of the cover panel  102  and the housing  104  in some embodiments. However, in some embodiments it may be preferable or necessary to employ suction to grasp one or both of the cover panel  102  and the housing  104 . In this regard, the cover panel  102  may be positioned in a flush or recessed configuration such that disassembly of the cover panel  102  from the housing  104  via mechanical interference-based grippers may be difficult or impossible. Further, use of suction may allow for distribution of loads, so as to avoid damaging, for example, the housing  104 . 
     Accordingly, the disassembly apparatus  200  may include one or more suction sources configured to produce suction. As may be understood the suction sources may comprise air pumps configured to produce suction. The suction may be applied to the tablet computing device  100  to provide coupling therebetween. 
     In the illustrated embodiment the first disassembly fixture  202  comprises a first suction source  216  and the second disassembly fixture  204  includes a second suction source  218 . However, in other embodiments a single suction source may be connected to both the first disassembly fixture  202  and the second disassembly fixture  204 . Alternatively, the first disassembly fixture  202  may include a suction source to couple to the cover panel  102  and the second disassembly fixture  204  may include physical means (e.g., interference-based grippers) to engage the housing  104  or conversely the second disassembly fixture  204  may include a second suction source to couple to the housing  104  and the first disassembly fixture  202  may include physical means (e.g., grippers) to engage the cover panel  102 , in embodiments in which such engagement is possible. However, for purposes of brevity the first disassembly fixture  202  and the second disassembly fixture  204  are generally described herein as each including a suction source. 
     As further illustrated in  FIG. 3 , in some embodiments the first disassembly fixture  202  and/or the second disassembly fixture  204  may include a body heater. In the illustrated embodiment the first disassembly fixture  202  includes a first body heater  220  and the second disassembly fixture  204  includes a second body heater  222 . The first body heater  220  and the second body heater  222  may be configured to heat the tablet computing device  100 . In this regard, by heating the tablet computing device  100 , the pressure sensitive adhesive  112  may be loosened such that disassembly of the tablet computing device is facilitated. 
     In order to transfer suction from the suction sources  216 ,  218  and transfer heat from the body heaters  220 ,  222  to the tablet computing device  100 , the first disassembly fixture  202  may comprise a first engagement body  224  and the second disassembly fixture  204  may comprise a second engagement body  226 . The engagement bodies  224 ,  226  may comprise materials such as brass or copper that are configured to transfer heat. The engagement bodies  224 ,  226  may be configured to engage a respective portion of the tablet computing device  100  so as to transfer suction and/or heat thereto. In particular, the first engagement body  224  may engage the cover panel  102  and the second engagement body  226  may engage the housing  104 . 
     The second disassembly fixture  204 , including the second engagement body  226  may be substantially similar to the first disassembly fixture  202 , including the first engagement body  224 . Accordingly, for brevity purposes, only the first disassembly fixture  202  and the first engagement body  224  are described in detail hereinafter. However, it should be understood that description with respect to the first disassembly fixture  202  may be equally applicable to the second disassembly fixture  204  in terms of physical features and interaction with an opposing portion (e.g., the housing  104 ) of the tablet computing device  100 . 
       FIG. 5  illustrates an overhead view of the first engagement body  224 . The first engagement body  224  may include a plurality of suction effectors  228  coupled thereto and configured to apply the suction produced by the first suction source  216  to the tablet computing device  100  to couple the tablet computing device to the first engagement body. Further, the first engagement body  224  may include a connector aperture  230  extending therethrough to one or more of the suction effectors  228 . For example, in the embodiment illustrated in  FIG. 5 , a respective connector aperture  230  is associated with each suction effector  228 . 
       FIG. 6  schematically illustrates a sectional view through the first disassembly fixture  202  of  FIG. 3  in an embodiment including the first engagement body  224  of  FIG. 5 . As illustrated, one embodiment of the suction effectors comprises round apertures  228 ′. In this regard, the first engagement body  224  may be sized and shaped to correspond to the size and shape of the cover panel  102  such that the round apertures  228 ′ may be in engagement therewith. 
     However, various other embodiments of suction effectors may be employed. For example,  FIG. 7  schematically illustrates a sectional view through the first disassembly fixture  202  of  FIG. 3  in an alternate embodiment including the first engagement body  224  of  FIG. 5 . As illustrated, in this embodiment the suction effectors comprise externally extending suction cups  228 ″. The suction cups  228 ″ may comprise an elastomeric material configured to conform to the shape of the cover panel  102 . 
     Accordingly, regardless of the particular embodiment, as illustrated in  FIGS. 6 and 7  the first engagement body  224  may direct suction produced by the first suction source  216  through the connector aperture  230  to the suction effector  228  (e.g., the round aperture  228 ′ or the suction cup  228 ″). As further illustrated in  FIGS. 6 and 7 , the first body heater  220  may be configured to heat substantially an entirety of the first engagement body  224 . In this regard, the first body heater  220  may comprise at least one cartridge, coil, or other mechanism configured to substantially evenly heat the first engagement body  224 . Accordingly, as noted above, the first body heater  220  may heat the first engagement body  224 , which may thereby heat the cover panel  102  so as to loosen the pressure sensitive adhesive  112 . Thereby, the disassembly apparatus  200  may employ heat and suction to disassemble the tablet computing device  100 . 
     However, in some instances use of the above-described disassembly apparatus  200  may suffer from certain problems. In this regard, as illustrated in  FIG. 8 , in some instances disassembly of the tablet computing device  100  may result in bending of the cover panel  102 . Bending of the cover panel  102  may be undesirable in that it may cause damage to the cover panel itself and/or damage to one or more components coupled thereto. For example, in embodiments in which the display assembly  108  and/or the electronic components  110  are directly or indirectly coupled to the cover panel  102 , bending of the cover panel may cause damage thereto. 
     Accordingly, embodiments of the present disclosure are configured to limit (e.g., substantially avoid) bending of the cover panel  102  and components coupled thereto. In this regard,  FIG. 9  illustrates an alternate embodiment of a disassembly apparatus  300 . The disassembly apparatus  300  illustrated in  FIG. 9  may be substantially similar to the disassembly apparatus illustrated in  FIG. 3  and described above. In this regard, the disassembly apparatus  300  of  FIG. 9  may include the first disassembly fixture  202  and the second disassembly fixture  204  and portions thereof including, for example, the first and second suction sources  216 ,  218 , the first and second body heaters  220 ,  222 , and the first and second engagement bodies  224 ,  226 . Additionally, the disassembly apparatus  300  may include the display  212  and/or the controller  214 . 
     However, the disassembly apparatus  300  may be configured to linearly displace the housing  104  away from the cover panel  102 . Accordingly, issues with respect to bending caused by hingedly disassembling the tablet computing device  100  may be substantially avoided. In this regard, linear disassembly may cause the cover panel  102  to disconnect from the housing  104  at all edges substantially simultaneously. 
     Thus, the disassembly apparatus  300  may include the actuator  206  and the load cell  210 . However, the actuator  206  may be configured to linearly displace the second disassembly fixture  204  from the first disassembly fixture  202 . In this regard, in the illustrated embodiment, the disassembly apparatus  300  further comprises a second actuator  232  and a second load cell  234 . Accordingly, the actuators  206 ,  232  may each press against the second disassembly fixture  204  to linearly displace the housing  104  from the cover panel  102 , as illustrated in  FIG. 10 . Further, the load cells  210 ,  234  may be employed (e.g., by the controller  214  or the operator) to ensure that separation force is evenly applied across the tablet computing device  100 . However, it should be understood that linear displacement and separation may be accomplished in other manners using a smaller or greater number of actuators and load cells. 
     Additional features may be configured to facilitate disassembly of devices such as the tablet computing device  100 . In this regard,  FIG. 11  illustrates an overhead view of a first disassembly fixture  402  according to an alternate embodiment of the present disclosure.  FIG. 12  schematically illustrates a sectional view through the first disassembly fixture  402  of  FIG. 11  and illustrates additional components thereof. The first disassembly fixture  402  may be employed in either of the disassembly apparatuses  200 ,  300  described above, or any other embodiment of disassembly apparatus. In this regard, the first disassembly fixture  402  of  FIG. 11  may be employed in place of the disassembly fixture  202  described above. Similarly, a second disassembly fixture may be substantially similar to the first disassembly fixture  402 . Accordingly, for purposes of brevity, details with respect to the second disassembly fixture will not be repeated. 
     As illustrated, the first disassembly fixture  402  may include a first engagement body  424 . One or more suction effectors may be coupled to the first engagement body  424 . In the illustrated embodiment, the suction effectors comprise a plurality of channels  428  defined in the engagement body  424 . In this regard, in the above-described embodiments the suction effectors  228  comprised round apertures  228 ′ or suction cups  228 ″ which only apply suction at each respective suction effector. Thereby, a large area is defined between each suction effector  228  that does not assist in bonding the tablet computing device  100  thereto. 
     However, in the embodiment illustrated in  FIG. 11 , the channels  428  extend across a large portion of the area formed by the surface of the first engagement body  424 . In this regard, suction is provided to the channels  428  via a connector aperture  430 , which is in communication with a first suction source  416 , as illustrated in  FIG. 12 . The channels  428  may include a connector channel  428 ′ and a plurality of concentric channels  428 ″ extending around the connector aperture  430 . Thus, suction may be transferred from the connector aperture  430  through the connector channel  428 ′ to the concentric channels  428 ″. The channels  428  may additionally include outer connector channels  428 ′″. The outer connector channels  428 ′″ may extend between the concentric channels  428 ″ to ensure that each concentric channel receives suction directed thereto. Although various other patterns may be employed, use of the concentric channels  428 ″ may be employed to ensure substantially even distribution of suction across the surface of the first engagement body  424 . 
     Further, a sealing member  436  may extend around the channels  428 . For example, the sealing member  436  may be received in a groove  438  defined in the first engagement body  424  and extending around the channels  428 . In some embodiments the sealing member  436  may comprise an elastomeric member such as silicone. The sealing member  436  may be configured to seal against the cover panel  102  such that suction is retained within the entirety of the area defined within the sealing member  436 . As illustrated in  FIG. 11 , the sealing member  436  may include a button portion  436 ′ configured to surround a button (e.g., the button  106 ) that is at least partially surrounded by the cover panel  102 . Thereby, issues with respect to undesirably applying suction to the button may be avoided. For example, suction applied to the button  106  may undesirably disengage the button from the remainder of the tablet computing device  100  and/or cause other issues. 
     Accordingly, as described above, use of the channels  428  and the sealing member  436  may allow suction to be applied to substantially the entirety of the cover panel  102  such that firm and even engagement between the first engagement body  424  and the cover panel may be achieved. Such even and firm engagement may assist in reducing bending of the cover panel  102  during disassembly of the tablet computing device  100 . However, the first disassembly fixture  402  may additionally or alternatively include other features configured to facilitate disassembly of the tablet computing device  100 . 
     By way of example, the first disassembly fixture  402  may include one or more alignment protrusions  440  configured to align the tablet computing device  100  with respect thereto. For example, the alignment protrusions  440  may extend from the first engagement body  424  on one or more sides of the section configured to engage the cover panel  102 . In embodiments including the alignment protrusions  440  on at least two sides, an operator or automated device may bring the tablet computing device  100  into contact therewith to ensure proper placement within the first disassembly fixture  402 . 
     Further, as further illustrated in  FIG. 11 , the first disassembly fixture  402  may include or more localized heaters  442 . The localized heaters  442  may be configured to respectively heat a localized portion of the cover panel  102 . The localized heaters  422  may be positioned and configured to align with the pressure sensitive adhesive  112  (or other glue or adhesive) included in the tablet computing device  100 . In this regard, in  FIG. 11  each of the localized heaters  442  is configured to align with a respective corner  100 C-F of the tablet computing device  100 , at which the pressure sensitive adhesive  112  is located. 
     Accordingly, by directing heat at a particular location on the tablet computing device  100 , the pressure sensitive adhesive  112  may be particularly targeted to facilitate release thereof. However, as illustrated in  FIG. 12 , the first disassembly fixture  402  may additionally include a first body heater  420 . The first body heater  420  may be configured to heat substantially the entirety of the first engagement body  424 . In this regard, the first body heater  420  may heat substantially the entirety of a surface of the cover panel  102  in contact with the first engagement body  224 . Thereby, the cover panel  102  may be heated to a base temperature that assists in separating the cover panel from the housing  104  may loosening the bond formed by the pressure sensitive adhesive  112 . However, it may be desirable to maintain the temperature to which the first body heater  420  heats the first engagement body  424  at or below a threshold temperature below which damage to any of the components of the tablet computing device  100  occurs. In this regard, certain components such as magnets may be damaged by excessive heat. In some embodiments the threshold temperature may comprise approximately from about 60 degrees Celsius to about 70 degrees Celsius, and preferably about 65 degrees Celsius, which may avoid damage to magnets and other components. The first body heater  420  may be configured to substantially maintain the temperature of the first engagement body  424  at or below the threshold temperature. 
     In contrast, the localized heaters  442  may be configured to heat the localized portions of the cover panel  102  to a second temperature that is higher than the first temperature to which the first body heater  420  heats the first engagement body  424  and the cover panel. However, in order to avoid damage to the components of the tablet computing device  100 , the heat may be applied locally, at selected portions of the tablet computing device at which the pressure sensitive adhesive  112  is located and at which heat sensitive components are not located. The temperature to which the first body heater  420  and/or the localized heaters heat may be monitored (e.g., via thermocouples) and controlled (e.g., by the controller  214 ). 
     Further, in order to avoid issues with respect to the heat from the localized heaters  442  damaging any heat-sensitive components of the tablet computing device  100 , the localized heaters may be configured for a limited period of time. For example, the localized heaters  442  may produce heat after separation force is applied between the cover panel  102  and the housing. In this regard, the localized heaters  442  may rapidly heat and then rapidly cool after heat is applied for a desired length of time. For example, current may be applied to the localized heaters from about 1 second to about 10 seconds, and preferably about 5 seconds in some embodiments in order to loosen the pressure sensitive adhesive  112  without unduly heating surrounding components of the tablet computing device. Additionally, in some embodiments active cooling (e.g., via a coolant flow through a portion of the first engagement body) may be employed to prevent the localized heaters from undesirably heating other portions of the tablet computing device  100 . 
     In some embodiments the localized heaters  442  may comprise ceramic heaters which may employ resistive heating to produce heat. Ceramic heaters may be desirable in that they may be configured to quickly heat and cool. However, various other embodiments of heaters may be employed. Further, various other heating mechanisms such as inductive heating or heating via light emitting diodes may be employed. 
     As illustrated in  FIG. 11 , each of the localized heaters  442  may be received in a respective cutout  444  defined in the first engagement body  424 . Accordingly, the localized heaters  442  may sit substantially flush with a remainder of the first engagement body  424 . A sealant (e.g., silicone) may be received in the cutouts  444  to prevent loss of suction therethrough. In this regard, the localized heaters  442  may include wires  446  extending therefrom and through the first engagement body  424  to a controller (e.g., the controller  214 ) for control thereof in the manner described herein. 
       FIGS. 13-15  illustrate perspective and top views of one of the localized heaters  442 . As illustrated, the localized heaters  442  may include holes  448  configured to receive fasteners to secure the localized heaters to the first engagement body  424 . Further, the localized heaters may include grooves therein. The grooves may include a lateral groove  450  and two end grooves  452 , such that the grooves are substantially symmetrical. The grooves  450 ,  452  may be configured to receive the sealing member  436  such that suction loss is substantially avoided at the localized heaters  442 . In particular, as illustrated in  FIG. 11 , the sealing member  436  may be received in the lateral groove  450  and one of the two end grooves  452  depending on the particular orientation of the localized heater. Thus, the symmetrical configuration of the grooves  450 ,  452  in the localized heaters  442  may allow for use of the localized heaters at each corner, rather than employing differing localized heaters at each corner. 
     A method for disassembling an electronic device is also provided. As illustrated in  FIG. 16 , the method may include engaging a first separable portion of an electronic device at operation  502 . Further, the method may include engaging a second separable portion of the electronic device at operation  504 . The method may also include heating a localized portion of the first separable portion of electronic device at operation  506 . Additionally, the method may include applying a force to separate the first separable portion from the second separable portion of the electronic device at operation  508 . 
     In some embodiments of the method heating the localized portion of the first separable portion of the electronic device at operation  506  may include heating the localized portion after beginning to apply the force. This configuration may apply tension to the pressure sensitive adhesive such that heating thereof may cause immediate separation. However, the localized heating may occur simultaneously with applying the force, or before applying the force in other embodiments. Further, applying the force to separate the first separable portion from the second separable portion at operation  508  may include linearly displacing the second separable portion from the first separable portion. However, separation may occur in other manners, such as via hinged or pivoting movement. 
     The method may also include heating substantially an entirety of a surface of the first separable portion. Heating substantially the entirety of the surface of the first separable portion may include heating the surface of the first separable portion to a first temperature that is less than a second temperature to which the localized portion is heated at operation  506 . Additionally, the method may include limiting the force below a threshold force.
