Technical Field
[0001] This application belongs to the field of hot pressing technology, and specifically relates to a pressing device. Background Technology
[0002] To bond release paper to glass, the release paper is first layered on the glass, and then a pressure device is used to apply force to the release paper against the glass, causing the adhesive on the release paper to adhere to the glass, thus bonding the release paper to the glass. In related technologies, the release paper is prone to shifting relative to the glass, resulting in substandard bonded release paper and glass. Utility Model Content
[0003] In view of the above situation, it is necessary to provide a pressing device that can press a first workpiece and a second workpiece together, and the first workpiece and the second workpiece are qualified after the connection.
[0004] This application provides a pressing device, including a worktable, a positioning assembly, a pressing member, and a fastening assembly. The positioning assembly is disposed on the worktable and includes a first positioning member and a second positioning member. The first positioning member has a through hole and a positioning pin, and the second positioning member passes through the through hole. The second positioning member is used to support and absorb a first workpiece, and the sidewall of the through hole abuts against the first workpiece. The first positioning member is used to support a second workpiece, such that the positioning pin is inserted into the second workpiece, and the second workpiece is stacked on top of the first workpiece. The pressing member is rotatably connected to the worktable and is used to apply force to the second workpiece towards the worktable. The fastening assembly includes a snap-fit member and a mating member. The mating member is disposed on the worktable, and the snap-fit member is rotatably connected to the pressing member and is used to snap the mating member when the pressing member applies force to the second workpiece towards the worktable.
[0005] In the aforementioned pressing device, the first positioning member accommodates the second positioning member through a through hole, allowing the sidewall of the through hole to abut against the first workpiece when the second positioning member adsorbs the first workpiece, thus positioning the first workpiece relative to the first positioning member. The first positioning member inserts the second workpiece through a positioning pin to position the second workpiece relative to the first positioning member, and the second workpiece is stacked on top of the first workpiece. A snap-fit component engages with the mating component to keep the pressing member applying force to the second workpiece toward the worktable, thus pressing the second workpiece onto the first workpiece. The positioning assembly fixes the first and second workpieces relatively to prevent relative displacement, ensuring that the connected first and second workpieces are qualified. When the aforementioned pressing device is applied to the pressing of release paper and glass, i.e., the first workpiece is glass and the second workpiece is release paper, the pressing device can position the glass and release paper, preventing relative displacement of the glass relative to the release paper, thus ensuring that the glass and release paper are properly pressed together.
[0006] In some embodiments, the positioning assembly further includes a clamping member, which includes a guide rod, a buffer, and a push block. The guide rod includes a stop surface and passes through the push block. The buffer connects the push block and the stop surface respectively. The push block passes through the worktable and the through hole. The guide rod can move relative to the push block in a first direction, so that the buffer elastically pushes the push block, and the push block pushes the first workpiece against the side wall opposite to the push block.
[0007] The guide rod moves, causing the buffer to elastically push the push block, which in turn pushes the first workpiece against the side wall. This clamps the first workpiece between the push block and the side wall along the first direction, thus more stably positioning the first workpiece within the through hole. The buffer also cushions and dampens the push block, preventing rigid collisions between the push block and the first workpiece that could damage it.
[0008] In some embodiments, the snap-fit component includes a snap hook, and the mating component has a snap groove. The snap-fit component rotates relative to the pressing component to cause the snap hook to engage or disengage from the snap groove.
[0009] By using a snap hook to engage with a slot, the snap hook engages with the mating part, thereby connecting the pressing part to the worktable so that the pressing part maintains a state of applying force to the second workpiece towards the worktable.
[0010] In some embodiments, the fastening assembly further includes a first elastic member and a pusher member. The pusher member is disposed on the pressure member. The first elastic member is connected to the latching member and the pressure member respectively. The pusher member is used to push the latching member toward the side away from the pressure member, so that the latch hook is away from the slot. The first elastic member is used to elastically deform to rotate the latching member, so that the latch hook engages with the slot.
[0011] When the abutting part does not abut against the locking part, the elastic deformation of the first elastic element causes the hook to move toward the locking groove, thereby engaging the hook with the locking groove. By pushing the locking part with the pushing part, the hook moves away from the locking groove, thus disengaging the hook from the locking groove.
[0012] In some embodiments, the pressing device further includes a driving assembly, which includes a power component and a guide component. The power component is connected to the guide component, the guide component is provided with a guide groove, the pressing component is provided with a guide post, the guide post passes through the guide groove, and the power component is used to drive the guide component to move in a third direction, so that the guide post drives the pressing component to rotate relative to the worktable under the guidance of the guide groove.
[0013] The guide component is driven by a power component to move, which in turn guides the guide post through the guide groove. This causes the guide post to rotate relative to the worktable under the guidance of the guide groove, so that the end of the pressure component near the fastening assembly moves toward or away from the worktable.
[0014] In some embodiments, the drive assembly further includes a second elastic member that elastically abuts against the pressure member and the worktable, and the elastic deformation of the second elastic member causes the end of the pressure member near the fastening assembly to move toward or away from the worktable.
[0015] When the end of the pressing component near the fastening assembly moves toward the worktable, the elastic element deforms elastically to buffer and dampen the pressing component, preventing it from crushing the second and first workpieces; the elastic element rebounds, causing the end of the pressing component near the fastening assembly to move away from the worktable.
[0016] In some embodiments, the pressure member is provided with a limiting pin, the worktable is provided with a limiting block, the limiting block is provided with a limiting hole, and the limiting pin is used to be inserted into the limiting hole when the pressure member applies force to the second workpiece toward the worktable.
[0017] The limiting hole positions the limiting pin to prevent the pressure piece from shifting relative to the worktable when it applies force to the worktable. The limiting hole also positions the insertion depth of the limiting pin to prevent the pressure piece from crushing the second and first workpieces when it applies force to the worktable.
[0018] In some embodiments, the second positioning member is connected to the driving member, the driving member passes through the worktable and is connected to the second positioning member, and is used to drive the second positioning member to move along a third direction, so that the second positioning member can drive the first workpiece to move toward the second workpiece.
[0019] The second positioning component is driven by the driving component to move toward the pressing component, thereby adjusting the position of the second workpiece in the third direction. The second bearing surface drives the first workpiece to move toward the second workpiece, so that the pressing component and the driving component press the second workpiece onto the first workpiece.
[0020] In some embodiments, the second positioning member includes an adsorption member and a heating member. The heating member is disposed on the periphery of the adsorption member, and the adsorption member and the heating member are connected to form a second bearing surface. The second bearing surface is used to bear the first workpiece. The adsorption member is provided with an adsorption groove that penetrates the second bearing surface. The adsorption member adsorbs the first workpiece in the second bearing surface through the adsorption groove. The heating member is used to heat the first workpiece in the second bearing surface.
[0021] The adsorption tank uses negative pressure to adsorb the first workpiece in the second bearing surface to position the first workpiece. The heating element heats the first workpiece when the second workpiece applies force to the worktable, so that the second workpiece can be heat-pressed onto the first workpiece, which is beneficial for the connection between the first and second workpieces.
[0022] In some embodiments, the first positioning element includes a first bearing surface and an adsorption hole. A positioning pin is disposed on the first bearing surface. The first bearing surface is used to bear the second workpiece. The adsorption hole penetrates the first bearing surface and is used to connect negative pressure to adsorb the second workpiece in the first bearing surface, so that the second workpiece will not move relative to the first workpiece.
[0023] After the positioning pin positions the second workpiece in the first bearing surface, the suction hole uses negative pressure to suction the second workpiece in the first bearing surface to further position the second workpiece so that the second workpiece will not move relative to the first workpiece.

[0038] In this document, the term "embodiment" means that a particular feature, structure, or characteristic described in connection with an embodiment may be included in at least one embodiment of this application. The appearance of this phrase in various places throughout the specification does not necessarily refer to the same embodiment, nor is it a separate or alternative embodiment that is mutually exclusive with other embodiments.
[0039] To bond release paper to glass, the release paper is first layered on the glass, and then a pressure device is used to apply force to the release paper against the glass, causing the adhesive on the release paper to adhere to the glass, thus bonding the release paper to the glass. In related technologies, the release paper is prone to shifting relative to the glass, resulting in substandard bonded release paper and glass.
[0040] During the manufacturing process, glass is used to connect to the phone case. Release paper with adhesive backing acts as a protective film, preventing scratches or other damage to the glass surface to maintain its integrity and aesthetics. The release paper also helps position the adhesive relative to the glass, allowing the adhesive to adhere to the outer perimeter of the glass, which in turn connects to the phone case.
[0041] This application provides a pressing device, including a worktable, a positioning assembly, a pressing member, and a fastening assembly. The positioning assembly is disposed on the worktable and includes a first positioning member and a second positioning member. The first positioning member has a through hole and a positioning pin, and the second positioning member passes through the through hole. The second positioning member is used to support and absorb a first workpiece, and the sidewall of the through hole abuts against the first workpiece. The first positioning member is used to support a second workpiece, such that the positioning pin is inserted into the second workpiece, and the second workpiece is stacked on top of the first workpiece. The pressing member is rotatably connected to the worktable and is used to apply force to the second workpiece towards the worktable. The fastening assembly includes a snap-fit member and a mating member. The mating member is disposed on the worktable, and the snap-fit member is rotatably connected to the pressing member and is used to snap the mating member when the pressing member applies force to the second workpiece towards the worktable.
[0042] In the aforementioned pressing device, the first positioning member accommodates the second positioning member through a through hole, allowing the sidewall of the through hole to abut against the first workpiece when the second positioning member adsorbs the first workpiece, thus positioning the first workpiece relative to the first positioning member. The first positioning member inserts the second workpiece through a positioning pin to position the second workpiece relative to the first positioning member, and the second workpiece is stacked on top of the first workpiece. A snap-fit component engages with the mating component to keep the pressing member applying force to the second workpiece toward the worktable, thus pressing the second workpiece onto the first workpiece. The positioning assembly fixes the first and second workpieces relatively to prevent relative displacement, ensuring that the connected first and second workpieces are qualified. When the aforementioned pressing device is applied to the pressing of release paper and glass, i.e., the first workpiece is glass and the second workpiece is release paper, the pressing device can position the glass and release paper, preventing relative displacement of the glass relative to the release paper, thus ensuring that the glass and release paper are properly pressed together.
[0043] The embodiments of this application will be further described below with reference to the accompanying drawings. Unless otherwise specified, the various embodiments in this application can be combined with each other.
[0044] Please see Figure 1 In this embodiment, the first direction, the second direction, and the third direction are defined to be perpendicular to each other. The first direction is the direction parallel to X in the figure, the second direction is the direction parallel to Y in the figure, and the third direction is the direction parallel to Z in the figure.
[0045] For ease of reference to the diagrams, the second direction will be referred to as "first direction X" in the following text, the third direction as "second direction Y", and the third direction as "third direction Z".
[0046] Please see Figure 1 This application provides a pressing device 100, including a worktable 10, a positioning assembly 20, a pressing member 30, and a fastening assembly 40 (see...). Figure 3A positioning component 20 is disposed on the worktable 10 and is used to position the first workpiece 200 and the second workpiece 300, fixing the first workpiece 200 relative to the second workpiece 300, with the second workpiece 300 stacked on top of the first workpiece 200. A pressing component 30 is rotatably connected to the worktable 10 to apply force to the second workpiece 300 towards the worktable 10, pressing the second workpiece 300 against the first workpiece 200. A fastening component 40 is used to fasten the pressing component 30 to the worktable 10 when the pressing component 30 is close to the worktable 10, keeping the pressing component 300 facing the second workpiece 300 towards the worktable 10, which facilitates pressing the second workpiece 300 against the first workpiece 200.
[0047] The positioning assembly 20 includes a first positioning element 21 and a second positioning element 22. The first positioning element 21 has a first bearing surface 2101. The second positioning element 22 has a second bearing surface 2201. The second bearing surface 2201 is used to support a first workpiece 200. The first bearing surface 2101 is used to support a second workpiece 300.
[0048] Please see Figure 2 The first positioning element 21 includes a through hole 2102, and the second positioning element 22 passes through the through hole 2102. When the second bearing surface 2201 supports the first workpiece 200, the second positioning element 22 can attract the first workpiece 200, and the side wall 2102a of the through hole 2102 abuts against the first workpiece 200 to position the first workpiece 200 relative to the first positioning element 21. The first bearing surface 2101 is provided with a positioning pin 211. When the first bearing surface 2101 supports the second workpiece 300, the second workpiece 300 is stacked on top of the first workpiece 200, and the positioning pin 211 is inserted into the second workpiece 300 to position the second workpiece 300 relative to the first positioning element 21.
[0049] Therefore, by positioning the first workpiece 200 and the second workpiece 300 by the positioning component 20, the first workpiece 200 and the second workpiece 300 are relatively fixed in the horizontal direction, which can prevent the first workpiece 200 and the second workpiece 300 from shifting relative to each other. As a result, after the pressing component 30 applies force to the second workpiece 300 toward the worktable 10, the first workpiece 200 and the second workpiece 300 are qualified after pressing.
[0050] Please see Figure 3 The fastening assembly 40 includes a snap-fit member 41 and a mating member 42. The mating member 42 is fixedly mounted on the worktable 10. The snap-fit member 41 is rotatably connected to the pressure member 30. The snap-fit member 41 is used to snap onto the mating member 42 when the pressure member 30 applies force to the second workpiece 300 toward the worktable 10.
[0051] In use, after the first workpiece 200 and the second workpiece 300 are positioned by the positioning component 20, the driving pressure component 30 is rotated relative to the worktable 10, so that the snap-fit component 41 snaps into the mating component 42. At this time, the pressure component 30 applies force to the second workpiece 300 toward the worktable 10, so that the second workpiece 300 is pressed against the first workpiece 200.
[0052] Please see Figure 7 In some embodiments, the second workpiece 300 is provided with a connecting hole 320 for inserting a positioning pin 211.
[0053] In some embodiments, the first workpiece 200 is glass, which can be installed on a mobile phone case or a tablet case. The second workpiece 300 is release paper with adhesive 310. When the pressure member 30 applies force to the second workpiece 300 toward the worktable 10, the release paper with adhesive 310 can be connected to the glass through the adhesive 310, thereby connecting the adhesive 310 and the release paper.
[0054] Please see Figure 4 and Figure 5 In some embodiments, the positioning assembly 20 further includes a clamping member 23. The clamping member 23 is mounted on the side of the worktable 10 facing away from the positioning assembly 20. Please refer to [link to relevant documentation]. Figure 5 The clamping member 23 includes a guide rod 231, a buffer member 232, and a push block 233. The guide rod 231 extends along a first direction X. The guide rod 231 includes a stop surface 2311. The stop surface 2311 faces the push block 233. The guide rod 231 passes through the push block 233, and the buffer member 232 connects the push block 233 and the stop surface 2311. The guide rod 231 can move relative to the push block 233 along the first direction X, causing the buffer member 232 to elastically push against the push block 233. Please refer to... Figure 1 Push block 233 is inserted into workbench 10 and through hole 2102.
[0055] When the guide rod 231 moves relative to the push block 233 along the first direction X, the stop surface 2311 can move away from or closer to the push block 233. When the stop surface 2311 moves closer to the push block 233, the stop surface 2311 applies force to the push block 233 through the buffer 232, and the push block 233 can push the first workpiece 200 against the side wall 2102a opposite to the push block 233, so that the push block 233 and the side wall 2102a clamp the first workpiece 200 along the first direction X, so as to more stably position the first workpiece 200 in the through hole 2102 and prevent the first workpiece 200 from swaying in the horizontal direction in the through hole 2102.
[0056] The guide rod 231 elastically pushes the push block 233 to move through the buffer 232, which can buffer the push block 233 and prevent the push block 233 from rigidly colliding with the first workpiece 200 and causing damage to the first workpiece 200.
[0057] In some embodiments, the buffer 232 is a spring. The spring is sleeved on the guide rod 231. The direction of the spring's elastic deformation is parallel to the first direction X. The force applied to the push block 233 by the spring can buffer and dampen the push block 233.
[0058] In some embodiments, the clamping member 23 further includes a linear drive structure 25. The linear drive structure 25 is mounted on the side of the worktable 10 facing away from the positioning assembly 20. The linear drive structure 25 is fixedly connected to a connecting rod and is used to drive the connecting rod to move along a first direction X, thereby causing the push block 233 and the side wall 2102a to clamp or release the first workpiece 200. The linear drive structure 25 includes a piston cylinder; when the piston cylinder shortens, the push block 233 and the side wall 2102a clamp the first workpiece 200. When the piston cylinder extends, the push block 233 and the side wall 2102a release the first workpiece 200.
[0059] In some embodiments, the push block 233 is provided with a bearing 2331. The guide rod 231 passes through the bearing 2331. The bearing 2331 is used to guide the guide rod 231 to move along a first direction X, so as to guide the movement direction of the push block 233 and prevent the push block 233 from shaking.
[0060] In some embodiments, the clamping member 23 further includes a slider 241 and a slide rail 242. The slider 241 is fixedly connected to the side of the worktable 10 facing away from the positioning assembly 20. The slide rail 242 is fixedly connected to the push block 233. The slider 241 is slidably connected to the slide rail 242, which extends along a first direction X to guide the slider 241 and the push block 233 to move along the first direction X, thereby guiding the movement direction of the push block 233 and enabling the push block 233 to move more stably along the first direction X under the action of the buffer member 232.
[0061] In some embodiments, the pusher 233 extends along the third direction Z. A through slot 101 extends along the third direction Z on the worktable 10 (see Figure 10). Figure 2 This allows the pusher block 233 to pass through the through groove 101 and the through hole 2102. The inner wall of the through groove 101 can also limit the range of movement of the pusher block 233.
[0062] In the illustrated embodiment, the third direction Z is parallel to the vertical direction. The first direction X is parallel to the horizontal direction. The horizontal direction is perpendicular to the vertical direction.
[0063] Please see Figure 1 and Figure 2In some embodiments, the second positioning member 22 includes an adsorption member 221 and a heating member 222. The heating member 222 is disposed on the periphery of the adsorption member 221, and the adsorption member 221 and the heating member 222 are connected to form a second bearing surface 2201. The adsorption member 221 has an adsorption groove 2211 that penetrates the second bearing surface 2201, and the adsorption groove 2211 is used to connect a negative pressure to adsorb the first workpiece 200 in the second bearing surface 2201. The heating member 222 is used to heat the first workpiece 200 in the second bearing surface 2201.
[0064] When the pusher block 233 adjusts the position of the first workpiece 200 along the first direction X and clamps the first workpiece 200 together with the side wall 2102a, the first workpiece 200 is adsorbed by the adsorption groove 2211 to further position the first workpiece 200 and prevent the first workpiece 200 from moving.
[0065] Please see Figure 1 and Figure 2 In some embodiments, the first positioning member 21 further includes an adsorption hole 2103. The adsorption hole 2103 extends through the first bearing surface 2101. The adsorption hole 2103 is used to connect a negative pressure to adsorb the second workpiece 300 in the first bearing surface 2101, so that the second workpiece 300 does not move relative to the first workpiece 200.
[0066] After the positioning pin 211 is inserted into the second workpiece 300, the second workpiece 300 is adsorbed through the adsorption hole 2103 to further position the second workpiece 300 and prevent it from moving.
[0067] The first workpiece 200 and the second workpiece 300 are positioned by the adsorption groove 2211 and the adsorption hole 2103. The positions of the first workpiece 200 and the second workpiece 300 are relatively fixed in both the horizontal and vertical directions, so that the second workpiece 300 will not shift relative to the first workpiece 200 when the pressing member 30 applies force to the second workpiece 300 toward the worktable 10. When the pressing member 30 applies force to the second workpiece 300 toward the worktable 10, the first workpiece 200 is heated by the heating member 222, so that the first workpiece 200 and the second workpiece 300 are pressed together by heat.
[0068] When the first workpiece 200 is glass and the second workpiece 300 is release paper with adhesive 310, the heating element 222 corresponds to the position of the adhesive 310 on the release paper. The heating element 222 heats the adhesive 310 and the area of the first workpiece 200 corresponding to the adhesive 310, so that the glass and the release paper are more firmly connected through the adhesive 310.
[0069] When the first workpiece 200 is glass with adhesive backing 310 and the second workpiece 300 is a mobile phone case, the pressing device 100 can also press the glass and the mobile phone case together.
[0070] Please see Figure 3In some embodiments, the snap-fit member 41 includes a snap hook 411. The mating member 42 is provided with a snap groove 421. The snap-fit member 41 rotates relative to the pressing member 30 to cause the snap hook 411 to engage or disengage from the snap groove 421.
[0071] In some embodiments, the latching member 41 engages with the slot 421 via the latching hook 411, thereby engaging the mating member 42, so that the pressing member 30 is connected to the worktable 10, so that the pressing member 30 maintains a state in which the second workpiece 300 applies force toward the worktable 10.
[0072] In some embodiments, the fastening assembly 40 further includes a first elastic member 43 and a pusher 44. The pusher 44 is disposed on the pressure member 30. The first elastic member 43 is connected to the latching member 41 and the pressure member 30 respectively. The pusher 44 is used to push the latching member 41 toward the side opposite to the pressure member 30, causing the latch hook 411 to move away from the latching groove 421, thereby causing the latch hook 411 to disengage from the latching groove 421. When the pusher 44 resets and disengages from the latching member 41, the first elastic member 43 rebounds, causing the latching member 41 to rotate, thereby causing the latch hook 411 to engage with the latching groove 421.
[0073] When the pusher 44 pushes the latching member 41, the latching member 41 rotates relative to the pressure member 30, the first elastic member 43 is elastically compressed, and the hook 411 moves away from the slot 421, thus disengaging the hook 411 from the slot 421, or preparing for the hook 411 to engage with the slot 421. When the pressure member 30 applies force to the second workpiece 300 toward the worktable 10, the pusher 44 cancels its contact with the latching member 41, the first elastic member 43 rebounds, the latching member 41 rotates relative to the pressure member 30, and the hook 411 moves toward the slot 421 to engage with the slot 421.
[0074] In some embodiments, the pusher 44 is a piston cylinder. When the pressure member 30 applies force to the second workpiece 300 toward the worktable 10, the pusher 44 is used to push the latching member 41 along the second direction Y. Specifically, the pusher 44 is used to push the end of the pusher 44 near the latch 411, causing the latch 411 to move away from the latching groove 421. The first elastic member 43 is a spring. The first elastic member 43 is connected to the end of the latching member 41 away from the latch 411 and the side of the pressure member 30 facing away from the worktable 10, so that the latching member 41 can be reset when the pusher 44 cancels the contact.
[0075] In some embodiments, the mating member 42 has an inclined surface 422 on the side facing away from the worktable 10. When the pressing member 30 applies force to the second workpiece 300 toward the worktable 10, the hook 411 abuts against the inclined surface 422 and slides into the groove along the inclined surface 422, thereby engaging the hook 411 with the groove 421.
[0076] During use, the pusher does not work before the hook 411 engages with the slot 421. After the second workpiece 300 presses against the first workpiece 200, the pusher works, thereby causing the hook 411 to disengage from the slot 421, so that the pressure plate 31 moves away from the worktable 10, in preparation for the next batch of second workpieces 300 to be pressed against the first workpiece 200.
[0077] In some embodiments, the first direction X and the second direction Y are two horizontal directions that are perpendicular to each other.
[0078] In some embodiments, there are two fastening structures. The two fastening structures are spaced apart along the first direction X, so that the pressure member 30 can be more stably connected to the workpiece stage. This application does not limit the number of fastening structures, and those skilled in the art can choose according to the actual situation.
[0079] In some embodiments, the two snap-fit pieces 41 are connected by a connecting shaft 45, so that the two snap-fit pieces 41 move synchronously, and the two snap hooks 411 simultaneously snap into or unsnap into the snap-fit slots 421.
[0080] In some embodiments, the pressure member 30 is provided with a rotating shaft (not shown) and is rotatably connected to the worktable 10 via the rotating shaft.
[0081] Please see Figure 1 and Figure 2 In some embodiments, the pressing device 100 further includes a drive assembly 50. The drive assembly 50 includes a power member 51 and a guide member 52. The power member 51 is connected to the guide member 52. The guide member 52 is provided with a guide groove 521. The pressing member 30 is provided with a guide post 321, which passes through the guide groove 521. The power member 51 is used to drive the guide member 52 to move in the third direction Z, so that the guide member 52 guides the guide post 321 to move through the guide groove 521. Under the guidance of the guide groove 521, the guide post 321 drives the pressing member 30 to rotate around the rotating axis relative to the worktable 10, so that the end of the pressing member 30 near the fastening assembly 40 moves toward or away from the worktable 10, thereby causing the pressing member 30 to apply force to the second workpiece 300 or release the second workpiece 300.
[0082] In some embodiments, the power component 51 is a piston cylinder. The piston cylinder is used to drive the guide 52 to move along a third direction Z.
[0083] Please see Figure 1In some embodiments, the guide groove 521 includes an inclined groove 521b and a straight groove 521a, the inclined groove 521b communicating with the straight groove 521a, and the straight groove 521a extending along the second direction Y. When the pressing member 30 rotates relative to the worktable 10 about the pivot, the guide post 321 moves along the guide groove 521, thereby adapting the guide groove 521 to the movement trajectory of the pressing member 30. When the guide post 321 is located at the end of the inclined groove 521b away from the straight groove 521a, and when the end of the pressing member 30 closest to the fastening assembly 40 is furthest from the worktable 10, please refer to [reference needed]. Figure 5 When the pressure member 30 applies force to the second workpiece 300 toward the worktable 10, the guide post 321 is located at the end of the straight groove 521a away from the inclined groove 521b.
[0084] Please see Figure 2 In some embodiments, the drive assembly 50 further includes a second elastic member 53. The second elastic member 53 elastically abuts against the pressure member 30 and the worktable 10. The elastic deformation of the second elastic member 53 causes the end of the pressure member 30 near the fastening assembly 40 to move toward or away from the worktable 10.
[0085] When the end of the pressing member 30 near the fastening assembly 40 moves toward the worktable 10, the second elastic member 53 elastically deforms to buffer and dampen the pressing member 30, preventing the pressing member 30 from crushing the second workpiece 300 and the first workpiece 200. When the end of the pressing member 30 near the fastening assembly 40 moves away from the worktable 10, the second elastic member 53 rebounds, causing the end of the pressing member 30 near the fastening assembly 40 to move away from the worktable 10.
[0086] In some embodiments, the second elastic element 53 is a torsion spring, with its two ends connected to the pressure member 30 and the worktable 10, respectively.
[0087] Please see Figure 2 In some embodiments, the pressure member 30 is provided with a limiting pin 322. The worktable 10 is provided with a limiting block 11. The limiting block 11 is provided with a limiting hole 111. Please refer to [link / reference]. Figure 6 The limiting pin 322 is used to be inserted into the limiting hole 111 when the pressing part 30 applies force to the second workpiece 300 toward the worktable 10.
[0088] The limiting pin 322 is positioned by the limiting hole 111 to prevent the pressure piece 30 from shifting relative to the worktable 10 when it applies force to the worktable 10. The limiting hole 111 can also position the insertion depth of the limiting pin 322 to limit the distance between the pressure piece 30 and the worktable 10, so as to prevent the pressure piece 30 from crushing the second workpiece 300 and the first workpiece 200 when it applies force to the worktable 10.
[0089] Please see Figure 4 In some embodiments, the second positioning member 22 is connected to the driving member 26. Please refer to... Figure 2The driving component 26 passes through the worktable 10 and is connected to the second positioning component 22. The driving component 26 is used to drive the second positioning component 22 to move along the third direction Z, so that the second positioning component 22 can drive the first workpiece 200 to move toward the second workpiece 300.
[0090] The second positioning member 22 is driven by the driving member 26 to move along the third direction Z to adjust the position of the second workpiece 300 in the third direction Z. The second bearing surface 2201 drives the first workpiece 200 to move toward the second workpiece 300, so that the pressing member 30 and the driving member 26 press the second workpiece 300 onto the first workpiece 200.
[0091] In some embodiments, the drive member 26 drives the second positioning member 22 to move along the third direction Z, and cooperates with the pressure member 30 to apply force to the release paper and glass, so that the release paper is connected to the glass through the backing adhesive 310, which can prevent the release paper from deforming.
[0092] In some embodiments, the drive element 26 is a servo electric cylinder.
[0093] In some embodiments, the drive member 26 is electrically connected to a pressure sensor (not shown) for sensing the pressure exerted by the drive member 26 and the pressure member 30 on the second workpiece 300 and the first workpiece 200, in order to prevent damage to the first workpiece 200 and the second workpiece 300.
[0094] The pressure sensor monitors the pressure of the drive component 26 and the pressure component 30 on the second workpiece 300 and the first workpiece 200 in real time. After the pressure is fed back to the PLC, the output power of the servo electric cylinder is increased or decreased through the servo electric cylinder driver, thereby increasing or decreasing the pressure to prevent damage to the first workpiece 200 and the second workpiece 300.
[0095] In use, the pusher 44 is not working. The drive assembly 50 drives the pressing member 30 to rotate around the pivot, causing the end of the pressing member 30 near the fastening assembly 40 to move towards the worktable 10. The hook 411 slides into the slot 421 along the inclined surface 422. The pressing member 30 maintains force on the second workpiece 300 towards the worktable 10. The heating member 222 heats the first workpiece 200 and the second workpiece 300. The drive assembly 26 drives the second positioning member 22 to lift the first workpiece 200 until the pressing member 30 and the drive assembly 26 press the second workpiece 300 onto the first workpiece 200. The pusher 44 then pushes against the fastening member 41, causing the hook 411 to disengage from the slot 421. The drive assembly 50 drives the pressing member 30 to rotate around the pivot, causing the end of the pressing member 30 near the fastening assembly 40 to move away from the worktable 10, preparing for the next batch of second workpieces 300 to be connected to the first workpiece 200.
[0096] In some embodiments, the pressure member 30 includes a pressure plate 31 and a connecting plate 32, with the pressure plate 31 fixedly disposed on the connecting plate 32. A snap-fit member 41, a limiting pin 322, a guide post 321, a second elastic member 53, and a pushing member 44 are all disposed on the connecting plate 32. The pressure plate 31 is used to apply force to the second workpiece 300 toward the worktable 10.
[0097] Furthermore, those skilled in the art should recognize that the above embodiments are merely illustrative of this application and are not intended to limit this application. Any appropriate changes and variations made to the above embodiments within the essential spirit and scope of this application fall within the scope of this application's disclosure.
