Description

Technical Field

[0001] This application relates to the field of assembly and processing technology, specifically to an assembly device. Background Technology

[0002] In the manufacturing process of electronic products, the common practice for assembling workpieces of varying sizes is to first use jigs to precisely position the larger parts, and then rely on manual labor to assemble the smaller parts. However, manual labor has significant drawbacks. Its procedures are complex and highly difficult, increasing the workload for workers and resulting in low production efficiency. Furthermore, due to the limited precision of manual operation, significant errors are easily introduced during assembly, making it difficult to meet the assembly accuracy requirements of electronic products, thus negatively impacting product quality and production efficiency. Utility Model Content

[0003] In view of the above, it is necessary to propose an assembly device that can assemble the first workpiece onto the second workpiece, which is easy to operate, reduces manual labor intensity, and improves work efficiency.

[0004] This application provides an assembly device for assembling a first workpiece onto a second workpiece. The first workpiece has a first through hole. The device includes: a carrying mechanism comprising a carrying component and two supporting members, the carrying component being used to position the second workpiece, and the two supporting members being respectively disposed on both sides of the second workpiece and connected to the carrying component; and an assembly mechanism comprising: a cover assembly detachably connected to the supporting members; a driving component comprising a driving member and a pressing unit, the pressing unit being movably disposed through the cover assembly; and an assembly component comprising two clamping members, two positioning members, and a pushing member, the two clamping members being adjacent and elastically connected to the pressing unit, the two positioning members being respectively disposed opposite to the two clamping members and elastically connected to the pressing unit, each clamping member being close to its corresponding... Each of the positioning members has a first inner support portion at one end, and each positioning member has a second inner support portion at one end near the corresponding clamping member. The pushing member is elastically connected to the pressing unit and abuts against the two clamping members. The pushing member is used to drive the two clamping members to move toward the corresponding positioning member so that the first inner support portion and the second inner support portion move closer to each other, so that the first through hole of the first workpiece can be sleeved on the outside of the first inner support portion and the second inner support portion. When the pushing member is released, the first inner support portion and the second inner support portion move away from each other to fix the first workpiece with internal support. The driving member drives the pressing unit to move toward the bearing component to drive the first workpiece to move toward the second workpiece, thereby assembling the first workpiece onto the second workpiece.

[0005] The aforementioned assembly device uses a carrying mechanism to position the second workpiece, a support member of the carrying mechanism to support the assembly mechanism, and the assembly mechanism to assemble the first workpiece onto the second workpiece. During assembly, the first workpiece is first installed onto the assembly assembly component of the assembly mechanism. During installation, the pushing member is pressed down, causing it to push two clamping members to move, so that the first inner support portion on each clamping member moves towards the second inner support portion of the corresponding positioning member. Then, the first workpiece is fitted onto the first and second inner supports through the first through hole. Releasing the pushing member causes the two first inner supports to elastically move away from the two second inner supports, thus supporting the first workpiece. The cover assembly is then flipped over and placed on the support member. The driving member in the drive assembly drives the pressing unit towards the carrying assembly, which in turn moves the assembly assembly towards the second workpiece on the carrying assembly, thus assembling the first workpiece onto the second workpiece. This assembly device, by installing the assembly mechanism onto the carrying mechanism and then driving the pressing unit to move, assembles the first workpiece onto the second workpiece. This convenient operation effectively reduces the labor intensity of operators and improves work efficiency.

Those skilled in the art can understand the specific meaning of the above terms in this application according to the specific circumstances.

[0027] The following will describe some embodiments of this application in detail with reference to the accompanying drawings.

[0028] Please see Figure 1 and Figure 2 This application provides an assembly device 100 for assembling a first workpiece 200 onto a second workpiece 300. The first workpiece 200 has a first through hole 201 and can be a small structural component. The first through hole 201 can be a rectangular hole. The second workpiece 300 can be a middle plate, middle frame, camera bracket, back cover, etc., of an electronic device, such as a mobile phone, tablet, computer, or speaker. In this embodiment, before assembling the first workpiece 200 and the second workpiece 300, an adhesive substance such as glue can be applied to either the first workpiece 200 or the second workpiece 300 to facilitate assembly after the first workpiece 200 comes into contact with the second workpiece 300. The assembly device 100 includes a support mechanism 10 and an assembly mechanism 20.

[0029] Specifically, the supporting mechanism 10 includes a supporting component 11 and two supporting members 12. The supporting component 11 is used to position the second workpiece 300, and the two supporting members 12 are respectively disposed on both sides of the second workpiece 300 and connected to the supporting component 11. The supporting mechanism 10 can position the second workpiece 300 by various methods such as clamping and adsorption, and the supporting members 12 can be block structures.

[0030] Please see also Figure 3 and Figure 4 The assembly mechanism 20 is detachably installed on the support mechanism 10. The assembly mechanism 20 includes a cover assembly 21, a drive assembly 22 and an assembly assembly 23.

[0031] The cover assembly 21 is detachably connected to the support member 12. The cover assembly 21 and the support member 12 can be connected by various methods such as snap-fit ​​and plug-in to ensure the stability of the cover assembly 21 after it is connected to the support member 12.

[0032] The drive assembly 22 includes a drive member 221 and a pressing unit 222. The drive member 221 is disposed on the side of the cover assembly 21 away from the support assembly 11. The pressing unit 222 is movably disposed through the cover assembly 21, and the end of the pressing unit 222 away from the support assembly 11 is connected to the drive member 221. The drive member 221 is used to drive the pressing unit 222 to move toward or away from the support assembly 11.

[0033] In this embodiment, the drive assembly 22 further includes a limiting cover 223. The limiting cover 223 is disposed on the side of the covering assembly 21 away from the bearing assembly 11 and covers the drive member 221. It is used to limit the drive member 221 in the vertical direction to prevent the drive member 221 from disengaging from the pressing unit 222.

[0034] Assembly component 23 includes two clamping members 231, two positioning members 232, and a pushing member 233, each disposed at one end of the pressing unit 222 near the bearing component 11. The two clamping members 231 are arranged adjacently and elastically connected to the pressing unit 222. The two positioning members 232 are respectively disposed opposite to the two clamping members 231 and are elastically connected to the pressing unit 222. Each clamping member 231 has a first inner support portion 2311 at one end near the corresponding positioning member 232, and each positioning member 232 has a second inner support portion 2311 at one end near the corresponding clamping member 231. The inner support portion 2321 and the pushing member 233 are elastically connected to the pressing unit 222 and abut against the two clamping members 231. The pushing member 233 is used to drive the two clamping members 231 to move toward the corresponding positioning member 232 so that the first inner support portion 2311 and the second inner support portion 2321 move closer to each other, so that the first through hole 201 of the first workpiece 200 can be sleeved on the outside of the first inner support portion 2311 and the second inner support portion 2321. When the pushing member 233 is released, the first inner support portion 2311 and the second inner support portion 2321 move away from each other to fix the first workpiece 200 with the inner support.

[0035] The clamping member 231 and the positioning member 232 are approximately L-shaped. One end of the clamping member 231 and one end of the positioning member 232 are elastically connected to the pressing unit 222 in the horizontal direction. The other end of the clamping member 231 and the other end of the positioning member 232 are both vertically away from the pressing unit 222. That is, the first inner support portion 2311 and the second inner support portion 2321 are arranged vertically away from the pressing unit 222. In this embodiment, the clamping member 231 and the positioning member 232 are arranged one-to-one opposite each other. That is, the clamping member 231 and the positioning member 232 can be divided into two pairs. The two pairs of clamping members 231 and positioning members 232 can be arranged in a cross shape to improve the stability when the first workpiece 200 is supported. Pressing the pusher 233 pushes the two first inner support portions 2311 toward their respective second inner support portions 2321. At this time, the first inner support portions 2311 and the second inner support portions 2321 move closer to each other, making it easier to fit the first workpiece 200 onto the outside of the first inner support portions 2311 and the second inner support portions 2321. After releasing the pusher 233, the first inner support portions 2311 move away from their corresponding second inner support portions 2321, thus internally supporting and fixing the first workpiece 200.

[0036] Among them, two first inner support parts 2311 and two second inner support parts 2321 are used to insert into the first through hole 201 of the first workpiece 200 to support the first workpiece 200. The driving member 221 drives the pressing unit 222 to move toward the bearing assembly 11 to drive the first workpiece 200 to move toward the second workpiece 300 so as to assemble the first workpiece 200 onto the second workpiece 300.

[0037] The second workpiece has a mounting groove 302, and the assembly component 23 is directly opposite the mounting groove 302 so that the first workpiece 200 can be assembled in the mounting groove 302. Specifically, the assembly device 100 provided in this application embodiment can position the second workpiece 300 through the bearing mechanism 10, and the support member 12 of the bearing mechanism 10 can support the assembly mechanism 20. The assembly mechanism 20 can assemble the first workpiece 200 into the second workpiece 300. During assembly, the first workpiece 200 is first installed on the assembly component 23 of the assembly mechanism 20. During installation, the pusher 233 is pressed down, and the pusher 233 pushes the two clamping members 231 to move, so that the first inner support part 2311 on each clamping member 231 moves toward the second inner support part 2321 of the corresponding positioning member 232 in order to reduce the distance between the first inner support part 2311 and the second inner support part 2321 to facilitate the installation of the first workpiece 200. At this time, the first workpiece 200 is sleeved on the first inner support part 2311 and the second inner support part 2321 through the first through hole 201. The pusher 233 is released, and the two first inner support parts 2311 elastically move away from the two second inner support parts 2321, thereby supporting the first workpiece 200. Then, the cover assembly 21 is flipped over and placed on the support member 12. The driving member 221 in the driving assembly 22 drives the pressing unit 222 to move towards the bearing assembly 11, thereby driving the assembly assembly 23 to move towards the second workpiece 300 on the bearing assembly 11, and thus assembling the first workpiece 200 into the middle position of the mounting groove 302 of the second workpiece 300. In the assembly device 100 described above, the assembly mechanism 20 is mounted on the bearing mechanism 10, and then the pressing unit 222 is driven by the driving member 221 to assemble the first workpiece 200 into the mounting groove 302 of the second workpiece 300. This method is convenient to operate, effectively reduces the labor intensity of operators, and thus improves work efficiency.

[0038] In some embodiments, see Figure 1 , Figure 2 and Figure 3 The driving component 221 includes a rotating ring 2211 and a driving rod 2212. The rotating ring 2211 is disposed on the side of the cover assembly 21 opposite to the support assembly 11. A driving groove 2213 is formed on the side wall of the rotating ring 2211. The driving groove 2213 has a first straight wall 2213a, an inclined wall 2213b, and a second straight wall 2213c connected in sequence. The driving rod 2212 is connected to the rotating ring 2211. The rotating ring 2211 has an annular structure and a through hole. The driving groove 2213 is an irregular groove. It can be understood that the first straight wall 2213a is a straight line, the inclined wall 2213b is an inclined plane, and the second straight wall 2213c is a straight line. In this embodiment, the height of the first straight wall 2213a is greater than the height of the second straight wall 2213c. The driving rod 2212 can be a columnar structure. Applying an external force to the driving rod 2212 can drive the rotating ring 2211 to move.

[0039] The pressing unit 222 includes a sliding block 2221 and a driving pin 2222. The sliding block 2221 slides vertically through the cover assembly 21, and the end of the sliding block 2221 away from the support assembly 11 is movably disposed within the rotating ring 2211. The driving pin 2222 is connected to the side wall of the sliding block 2221 and slidably disposed in the driving groove 2213. The sliding block 2221 can be a prism structure, and the driving pin 2222 can be a rod-shaped structure. The driving rod 2212 is used to drive the rotating ring 2211 to rotate vertically, so that the driving pin 2222 slides from the first straight wall 2213a through the inclined wall 2213b into the second straight wall 2213c, thereby driving the sliding block 2221 to move towards the support assembly 11.

[0040] In this embodiment, the cover assembly 21 has a sliding hole 2112 with a rounded rectangular cross-section. A sliding block 2221 slides through the sliding hole 2112, and its cross-section is also a rounded rectangle that matches the sliding hole 2112. This prevents the sliding block 2221 from rotating when the rotating ring 2211, in conjunction with the drive pin 2222, moves vertically. It is understood that the cross-section of the sliding hole 2112 can also be any structure other than a circle, as long as the cross-section of the sliding block 2221 matches the sliding hole 2112, as long as it restricts the rotational movement of the sliding block 2221.

[0041] In this embodiment, two drive grooves 2213 can be provided on the rotating ring 2211. The two drive grooves 2213 are symmetrically arranged about the axis of the rotating ring 2211. Two drive pins 2222 can be correspondingly provided on the sliding block 2221. Each drive pin 2222 is slidably disposed in the corresponding drive groove 2213. This can improve the stability of the rotating ring 2211 driving the sliding block 2221 to move.

[0042] In some embodiments, see Figure 1 , Figure 2 and Figure 3 The sliding block 2221 is located at one end of the rotating ring 2211 and has a vertically extending receiving groove 2221a. The side wall of the sliding block 2221 has a floating hole 2221b communicating with the receiving groove 2221a. The pressing unit 222 also includes a floating block 2223 and a floating elastic element 2224. The floating block 2223 is movably disposed in the receiving groove 2221a. The driving pin 2222 is fixedly connected to the floating block 2223 and movably inserted into the floating hole 2221b. The floating elastic element 2224 is disposed in the receiving groove 2221a, and both ends of the floating elastic element 2224 abut against the bottom of the receiving groove 2221a and the floating block 2223, respectively.

[0043] The floating hole 2221b can be a strip-shaped hole or an elliptical hole, the floating block 2223 can be a block structure, and the floating elastic element 2224 can be a spring. When the rotating ring 2211 rotates, the floating block 2223 and the sliding block 2221 can be driven to move through the driving pin 2222. When the sliding block 2221 moves to the lower limit position, the first workpiece 200 connected to the assembly assembly 23 abuts against the second workpiece 300. At this time, the floating elastic element 2224 can be compressed, and the sliding block 2221 can move relative to the driving pin 2222 through the floating hole 2221b, which plays a buffering role and prevents the first workpiece 200 from rigidly contacting the second workpiece 300 and causing damage.

[0044] In some embodiments, see Figure 3 , Figure 4 and Figure 5 The pressing unit 222 also includes a receiving box 2225, which includes a cover 2225a and a body 2225b connected to each other. The cover 2225a is connected to the end of the sliding block 2221 away from the rotating ring 2211. The body 2225b has multiple sliding grooves 2225c on the side facing the cover 2225a, and a limiting part 2225d on the side of the body 2225b away from the cover 2225a. The body 2225b also has a movable hole 2225e that passes through the limiting part 2225d vertically and communicates with the multiple sliding grooves 2225c. The cover 2225a is fixedly connected to the sliding block 2221. In this embodiment, the cover 2225a and the sliding block 2221 can be integrally molded to improve the stability of the connection between the cover 2225a and the sliding block 2221. In this embodiment, to further improve the accuracy of the position of the receiving box 2225, multiple springs can be provided between the lid 2225a and the closing assembly 21. The springs push against the lid 2225a to prevent the position of the receiving box 2225 from shifting during assembly. The number of sliding grooves 2225c can be four, five, six, etc., and each sliding groove 2225c is arranged in a horizontal direction.

[0045] The clamping member 231 further includes a first sliding portion 2312 disposed opposite to the first inner support portion 2311. The first sliding portion 2312 is slidably disposed in a corresponding sliding groove 2225c. The first inner support portion 2311 is movably disposed in the movable hole 2225e and extends out in a vertical direction with a limiting portion 2225d. The positioning member 232 further includes a second sliding portion 2322 disposed opposite to the second inner support portion 2321. The second sliding portion 2322 is slidably disposed in a corresponding sliding groove 2225c. The second inner support portion 2321 is movably disposed in the movable hole 2225e and extends out in a vertical direction with a limiting portion 2225d. The limiting portion 2225d is used to abut against the first workpiece 200 when the first inner support portion 2311 and the second inner support portion 2321 support the first workpiece 200, thereby limiting the position of the first workpiece 200. The first sliding part 2312 and the second sliding part 2322 are both arranged horizontally, and the first inner support part 2311 and the second inner support part 2321 are both arranged vertically, so that the first inner support part 2311 and the second inner support part 2321 can cooperate with each other to support the first workpiece 200. It can be understood that when the limiting part 2225d on the housing 2225b supports the first workpiece 200 with the first inner support part 2311 and the second inner support part 2321, it can resist the first workpiece 200 and play a reliable limiting role. This not only prevents the first workpiece 200 from unnecessary displacement during the assembly process and ensures the accuracy of the assembly action, but also provides additional support force for the first workpiece 200, making the first workpiece 200 more stable when subjected to the pressure of the pressing unit 222. This helps to smoothly complete the assembly process of the first workpiece 200 and the second workpiece 300, and improves the stability and reliability of the entire assembly operation.

[0046] In some embodiments, see Figure 4 , Figure 5 and Figure 6 The assembly component 23 also includes two first limiting pins 234, two second limiting pins 235, two first elastic elements 236, and two second elastic elements 237. The first elastic elements 236 and the second elastic elements 237 can both be elastic structural components such as springs.

[0047] Each first sliding part 2312 has a first receiving hole 2313. Each first limiting pin 234 is connected to the housing 2225b and inserted into each first receiving hole 2313. Each first elastic member 236 is disposed in each first receiving hole 2313, and both ends of each first elastic member 236 abut against the corresponding first limiting pin 234 and the inner wall of the corresponding first receiving hole 2313 away from the movable hole 2225e. The first elastic member 236 is used to push the first sliding part 2312 away from the movable hole 2225e. In this way, by setting the first elastic member 236, the first sliding part 2312 can be pushed to drive the first inner support part 2311 away from the corresponding second inner support part 2321, so that when the clamping member 231 is not subjected to external force, the first inner support part 2311 can internally support the first workpiece 200. The distance that the clamping member 231 can move away from the movable hole 2225e can be limited by the first limiting pin 234 abutting against the inner wall of the first receiving hole 2313 near the movable hole 2225e.

[0048] Each second sliding part 2322 has a second receiving hole 2323. Each second limiting pin 235 is connected to the housing 2225b and inserted into each second receiving hole 2323. Each second elastic member 237 is disposed in each second receiving hole 2323, and both ends of each second elastic member 237 abut against the corresponding second limiting pin 235 and the inner wall of the corresponding first receiving hole 2313 facing the movable hole 2225e. The second elastic member 237 is used to push the second sliding part 2322 towards the movable hole 2225e, and the second limiting pin 235 is used to abut against the inner wall of the second receiving hole 2323 away from the movable hole 2225e to limit the second sliding part 2322. The elastic force of the second elastic member 237 is greater than the elastic force of the first elastic member 236. Thus, when the second elastic member 237 pushes against the second sliding part 2322 to move to its maximum distance, the inner wall of the second receiving hole 2323 away from the movable hole 2225e can abut against the second limiting pin 235 to limit the positioning member 232 and ensure the accuracy of the position of the second inner support part 2321. When the first workpiece 200 is sleeved on the first inner support part 2311 and the second inner support part 2321, the second inner support part 2321 can be used as a positioning reference to improve the positioning accuracy of the first workpiece 200.

[0049] In some embodiments, see Figure 4 , Figure 5 and Figure 6The assembly component 23 also includes a third limiting pin 238 and a reset elastic member 239. A pusher 233 is slidably disposed in one of the sliding grooves 2225c and abuts against two first sliding portions 2312. The pusher 233 has a third receiving hole 2331. The third limiting pin 238 is connected to the housing 2225b and inserted into the third receiving hole 2331. The reset elastic member 239 is disposed in the third receiving hole 2331, with both ends abutting against the inner walls of the third limiting pin 238 and the third receiving hole 2331 away from the movable hole 2225e, respectively. The reset elastic member 239 is used to push the pusher 233 out of the housing 2225b. The pusher 233 moves towards the housing 2225b under external force and pushes the two first sliding portions 2312 towards the movable hole 2225e, thereby causing the two first inner support portions 2311 to move towards the corresponding second inner support portions 2321.

[0050] The reset elastic element 239 can be an elastic structural element such as a spring. The pushing element 233 is approximately L-shaped, with both ends of the pushing element 233 abutting against the first sliding portions 2312 of the two clamping elements 231, respectively. Specifically, one end of the pushing element 233 can directly abut against the first sliding portion 2312, while the other end can be provided with an inclined surface, which pushes the other first sliding portion 2312 to move. When installing the first workpiece 200, pressing the pushing element 233 causes it to push the two first sliding portions 2312 toward the movable hole 2225e, thereby driving the two first inner support portions 2311 to move toward the corresponding second inner support portions 2321, and then the first workpiece 200 can be placed. After the first workpiece 200 is fitted onto the two first inner support parts 2311 and the two second inner support parts 2321, the pusher 233 is released, the reset elastic member 239 pushes the pusher 233 back to its original position, and the two first sliding members respectively drive the two first inner support parts 2311 away from the corresponding second inner support parts 2321, thereby supporting the first workpiece 200.

[0051] In some embodiments, see Figure 4 , Figure 5 and Figure 6 The assembly mechanism 20 also includes two traction components 24 that correspond one-to-one with the positioning component 232. Each traction component 24 includes a top block 241, a traction component 242, and a third elastic component 243.

[0052] The top block 241 is slidably disposed on the side of the cover assembly 21 away from the support assembly 11 and abuts against the rotating ring 2211. The top block 241 can be a columnar or strip-shaped structure, and the end of the top block 241 that abuts against the rotating ring 2211 can be set as an arc-shaped or semi-circular structure to facilitate relative sliding between the top block 241 and the rotating ring 2211.

[0053] The traction member 242 includes an abutment portion 2421, a moving portion 2422, and a traction portion 2423. The abutment portion 2421 and the traction portion 2423 are respectively disposed at both ends of the moving portion 2422. The abutment portion 2421 passes vertically through the cover assembly 21, and the end of the abutment portion 2421 away from the moving portion 2422 is disposed opposite to the top block 241. The moving portion 2422 is slidably connected to the side of the cover assembly 21 facing the support assembly 11. The traction portion 2423 is disposed vertically away from the cover assembly 21. The abutment portion 2421, the moving portion 2422, and the traction portion 2423 can all be rod-shaped structures. The moving portion 2422 is slidably connected to the cover assembly 21 in the horizontal direction.

[0054] The third elastic member 243 is disposed between the top block 241 and the abutting part 2421. The third elastic member 243 is used to push the abutting part 2421 away from the top block 241. The third elastic member 243 can be an elastic structural member such as a spring.

[0055] Please see also Figure 7 and Figure 8 The second sliding part 2322 has a traction hole 2324, and the traction part 2423 is movably inserted into the traction hole 2324. Two protrusions 2214 extending away from the center of the rotating ring 2211 are spaced apart on the outer wall of the rotating ring 2211. When the drive pin 2222 slides along the second straight wall 2213c, each protrusion 2214 pushes against the corresponding top block 241, moving away from the rotating ring 2211. The third elastic member 243 pushes against the corresponding traction member 242, moving away from the pressing unit 222. The traction member 242 pulls the corresponding positioning member 232 away from the axis of the movable hole 2225e, thereby pulling the first workpiece 200 to move. The elastic force of the third elastic member 243 is greater than that of the second elastic member 237. The side of the protrusion 2214 facing the corresponding top block 241 can be set as an inclined surface to facilitate the movement of the protrusion 2214 against the corresponding top block 241 away from the rotating ring 2211.

[0056] In this embodiment, the assembly of the first workpiece 200 is divided into two stages. In the first stage, the drive pin 2222 slides from the first straight wall 2213a to the junction of the inclined wall 2213b and the second straight wall 2213c. During this process, the drive pin 2222 drives the sliding block 2221 to move toward the support assembly 11, and the receiving box 2225 drives the assembly assembly 23 to move toward the support assembly 11. The first workpiece 200, supported by the clamping member 231 and the positioning member 232 of the assembly assembly 23, moves toward the second workpiece 300 on the support assembly 11 until the first workpiece 200 abuts against the mounting groove 302 in the second workpiece 300. At this time, the rotating ring 2211 slides relative to the top block 241, and the protrusion 2214 does not push against the top block 241. Second stage: Drive pin 2222 moves away from inclined wall 2213b along second straight wall 2213c. During this process, the position of sliding member, receiving box 2225 and assembly assembly 23 in the vertical direction remains unchanged, that is, the position of first workpiece 200 in the vertical direction remains unchanged. Protrusion 2214 pushes the corresponding top block 241 away from rotating ring 2211. Top block 241 squeezes third elastic member 243. Third elastic member 243 pushes the abutting part 2421 of traction member 242 away from rotating ring 2211. Abutting part 2421 pulls the corresponding positioning member 232 through moving part 2422 and traction part 2423, so that positioning member 232 moves away from corresponding clamping member 231, thereby pulling first workpiece 200 toward the position of positioning member 232, and then pulling first workpiece 200 to move and fit against the side wall of mounting groove 302.

[0057] It is understandable that when the first workpiece 200 is assembled to the second workpiece 300, the second workpiece 300 usually has a structure such as a mounting groove 302 to accommodate the first workpiece 200. If the side of the first workpiece 200 is directly installed opposite the side wall of the mounting groove 302, it often causes the first workpiece 200 to rub against the side wall of the mounting groove 302, resulting in damage to the first workpiece 200, or the side wall of the first workpiece 200 and the mounting groove 302 to intersect, making it impossible for the first workpiece 200 to be assembled to the second workpiece 300. If the installation is based on the center of the mounting groove 302, the position of the first workpiece 200 assembled to the second workpiece 300 is often not accurate enough.

[0058] In this embodiment, in the first stage, the driving component 22 can drive the assembly component 23 to abut the first workpiece 200 against the middle position of the mounting groove 302 of the second workpiece 300. In the second stage, the traction component 24 can pull the two positioning members 232 of the assembly component 23 to move, thereby moving the first workpiece 200 to two sides corresponding to the two positioning members 232 respectively. This can adjust the position of the first workpiece 200 in the mounting groove 302, improve the positional accuracy of the first workpiece 200, and avoid the first workpiece 200 and the second workpiece 300 from being damaged due to friction with the side wall when the first workpiece 200 is directly installed into the mounting groove 302.

[0059] In this embodiment, the elastic force of the third elastic member 243 is greater than that of the second elastic member 237. When the top block 241 pushes against the traction member 242 via the third elastic member 243, causing the positioning member 232 to move, the second elastic member 237 can be compressed, thus allowing the positioning member 232 to move. The elasticity of the second elastic member 237 is greater than that of the first elastic member 236. When the positioning member 232 pulls the first workpiece 200 to move, the first elastic member 236 can be compressed, thus allowing the clamping member 231 to move with the first workpiece 200.

[0060] In some embodiments, see Figure 1 , Figure 3 and Figure 4 The cover assembly 21 includes a support plate 211 and positioning posts 212 connected to the support plate 211 and facing the support member 12. The support member 12 has positioning holes 121 corresponding to the positioning posts 212. The positioning posts 212 are inserted into the positioning holes 121 to position the support plate 211. The positioning posts 212 can be columnar structures extending vertically, and the structure of the positioning holes 121 is adapted to the structure of the positioning posts 212. It can be understood that, in order to improve the stability of positioning, multiple positioning posts 212 can be provided on the support plate 211, and multiple positioning holes 121 can be provided on the support member 12.

[0061] In some embodiments, see Figure 1 , Figure 3 and Figure 4The bearing mechanism 10 also includes two clamping components 13. The two clamping components 13 are disposed on both sides of the bearing component 11 and close to the support member 12. The clamping component 13 includes a connecting rod 131 and a clamping handle 132. The connecting rod 131 is rotatably connected to the bearing component 11, and the clamping handle 132 is rotatably connected to the end of the connecting rod 131 away from the bearing component 11. The support plate 211 has a snap-fit ​​hole 2111 corresponding to the connecting rod 131. The connecting rod 131 is used to snap into the snap-fit ​​hole 2111, and the clamping handle 132 is used to rotate and press the support plate 211. The clamping handle 132 may have an eccentric protrusion structure. When the support plate 211 is placed on the support member 12, the connecting rod 131 can be rotated so that the connecting rod 131 is clamped with the corresponding clamping hole 2111. Then, the clamping handle 132 is rotated, and the support plate 211 is pressed onto the support member 12 through the eccentric protrusion structure of the clamping handle 132, so as to improve the stability of the connection between the support plate 211 and the support member 12.

[0062] In some embodiments, see Figure 1 , Figure 3 and Figure 4 The second workpiece 300 has a second through hole 301. The second through hole 301 can be a hole at any position inside the second workpiece 300, which can be machined separately or used as a hole for other machining on the second workpiece 300.

[0063] The support assembly 11 includes a support plate 111, a positioning pin 112, multiple fixing pins 113, a movable side pusher 114, and a positioning handle 115. The support plate 111 is used to support the second workpiece 300. The positioning pin 112 and multiple fixing pins 113 are all disposed on the side of the support plate 111 used to support the second workpiece 300. The positioning pin 112 is correspondingly disposed with the second through hole 301, and the multiple fixing pins 113 are correspondingly disposed with the side of the second workpiece 300. The movable side pusher 114 is slidably connected to the support plate 111 and is spaced apart from the positioning pin 112. The positioning handle 115 is connected to the support plate 111 and abuts against the movable side pusher 114. The positioning handle 115 is used to push the movable side pusher 114 toward the second workpiece 300 so that the movable side pusher 114 pushes the second workpiece 300 to the fixing pin 113, thereby positioning the second workpiece 300.

[0064] When the support assembly 11 positions the second workpiece 300, it places the second workpiece 300 between multiple fixing parts of the support plate 111 and inserts the positioning pin 112 into the second through hole 301. Then, by positioning and driving the movable side pusher 114, the second workpiece 300 is pushed to move. The second workpiece 300 rotates around the positioning pin 112 until the movable side pusher 114, together with multiple fixing pins 113, clamps the second workpiece 300, thus completing the positioning of the second workpiece 300.

[0065] The working process of the assembly device 100 provided in this embodiment is roughly as follows:

[0066] First, the second workpiece 300 is positioned on the support plate 111 of the support assembly 11. The positioning pin 112 in the support assembly 11 corresponds to the second through hole 301 of the second workpiece 300, and multiple fixing pins 113 correspond to the sides of the second workpiece 300. Then, by operating the positioning handle 115, it pushes the movable side pusher 114 towards the second workpiece 300. The movable side pusher 114 then pushes the second workpiece 300 until it is in close contact with the fixing pins 113, thereby achieving precise positioning of the second workpiece 300 from multiple directions and ensuring that it maintains a stable position during subsequent assembly.

[0067] Then, an external force is applied to the pusher 233, causing the pusher 233 to move toward the box 2225b. The pusher 233 will push the two first sliding parts 2312 to move along the corresponding sliding grooves 2225c toward the movable hole 2225e, thereby driving the two first inner support parts 2311 to move toward the corresponding second inner support parts 2321, so that a suitable distance is formed between the first inner support parts 2311 and the second inner support parts 2321, which is convenient for placing the first workpiece 200. That is, the first through hole 201 of the first workpiece 200 is aligned with the first inner support parts 2311 and the second inner support parts 2321, and the first through hole 201 of the first workpiece 200 is sleeved on the outside of the first inner support parts 2311 and the second inner support parts 2321, and the first workpiece 200 abuts against the limiting part 2225d of the box 2225b. After the external force is removed, under the action of the reset elastic member 239, the pushing member 233 resets, and the first elastic member 236 pushes the clamping member 231 away from the corresponding positioning member 232, thereby allowing the first inner support portion 2311 and the second inner support portion 2321 to internally support the first workpiece 200. Adhesive or double-sided tape can be applied to the upper surface of the first workpiece 200. In other embodiments, adhesive or double-sided tape can also be applied, depending on the assembly requirements.

[0068] Next, the assembly mechanism 20 is flipped so that the upper surface of the first workpiece 200 faces downwards. The assembly mechanism 20 is then fastened onto the support member 12 of the bearing mechanism 10. During installation, the positioning pin 212 on the support plate 211 is inserted into the positioning hole 121 on the support member 12 to position the support plate 211. Then, the connecting rod 131 is rotated so that it engages with the corresponding engaging hole 2111. Then, the holding handle 132 is rotated, and the eccentric protrusion structure of the holding handle 132 presses the support plate 211 onto the support member 12.

[0069] Finally, the drive handle is rotated to drive and rotate the rotating ring 2211, thereby assembling the first workpiece 200 onto the second workpiece 300. This process is divided into two stages. In the first stage, the drive pin 2222 slides from the first straight wall 2213a to the junction of the inclined wall 2213b and the second straight wall 2213c. During this process, the drive pin 2222 drives the sliding block 2221 to move toward the support assembly 11, and the receiving box 2225 drives the assembly assembly 23 to move toward the support assembly 11. The first workpiece 200, supported by the clamping member 231 and the positioning member 232 of the assembly assembly 23, moves toward the second workpiece 300 on the support assembly 11 until the first workpiece 200 abuts against the middle position of the mounting groove 302 of the second workpiece 300. At this time, the rotating ring 2211 slides relative to the top block 241, and the protrusion 2214 does not push against the top block 241. Second stage: Drive pin 2222 moves away from inclined wall 2213b along second straight wall 2213c. During this process, the position of sliding member, receiving box 2225 and assembly assembly 23 in the vertical direction remains unchanged, that is, the position of first workpiece 200 in the vertical direction remains unchanged. Protrusion 2214 pushes the corresponding top block 241 away from rotating ring 2211. Top block 241 squeezes third elastic member 243. Third elastic member 243 pushes the abutting part 2421 of traction member 242 away from rotating ring 2211. Abutting part 2421 pulls the corresponding positioning member 232 through moving part 2422 and traction part 2423, so that positioning member 232 moves away from corresponding clamping member 231, thereby pulling first workpiece 200 toward the position of positioning member 232, and then pulling first workpiece 200 to move and fit against the side wall of mounting groove 302.
