[0022] Some embodiments of the present application will be described in detail below with reference to the accompanying drawings. In order to facilitate understanding and description of the embodiments of the present application, a three-dimensional coordinate system is established in part of the drawings. The X-axis direction is the first direction, the Z-axis direction is the second direction, and the Y-axis direction is the third direction. The X-axis direction, the Y-axis direction and the Z-axis direction are perpendicular to each other.

[0023] Please refer to Figure 1 , Figure 2 and Figure 3 , the present application provides an assembly jig 100 for assembling a first workpiece 200 and a second workpiece 300. The first workpiece 200 can be a metal back shell, a glass panel or other structural parts of electronic products such as mobile phones and tablets. The second workpiece 300 can be a sheet-shaped structural part. The assembly jig 100 comprises a base 10, a first positioning mechanism 20, a driving member 30 and a second positioning mechanism 40.

[0024] Specifically, the base 10 comprises a bottom plate 11 and a cover plate 12 arranged on the bottom plate 11. The bottom plate 11 is provided with a receiving groove 111 on the side facing the cover plate 12. The side of the cover plate 12 away from the bottom plate 11 is used to carry the first workpiece 200.

[0025] The first positioning mechanism 20 comprises a traction frame 21 slidably arranged in the receiving groove 111, a material carrying assembly 22 and a pressing assembly 23. The inner wall of the traction frame 21 is provided with a guide inclined groove 211. The material carrying assembly 22 comprises a material carrying seat 221 arranged on the bottom plate 11 and a clamping member 222 slidably arranged on the material carrying seat 221. The clamping member 222 and the material carrying seat 221 are used to clamp the second workpiece 300. The pressing assembly 23 is arranged on the traction frame 21 and located on the side of the clamping member 222 away from the material carrying seat 221.

[0026] The traction frame 21 can be a mouth-shaped structure. The guide inclined groove 211 on the traction frame 21 can be provided with two, and the two guide inclined grooves 211 are respectively located on the two side arms of the traction frame 21 in the Y-axis direction. It can be understood that when the second workpiece 300 is placed on the material carrying seat 221, one side of the second workpiece 300 in the X-axis direction is opposite to the clamping member 222. The clamping member 222 can be a block-shaped structure, which is used to clamp the second workpiece 300 with the material carrying seat 221.

[0027] The driving member 30 is in driving connection with the traction frame 21, and the driving member 30 is used to drive the traction frame 21 to slide along the X-axis direction relative to the bottom plate 11, so that the abutting assembly 23 abuts against the clamping member 222, and then the second workpiece 300 is clamped to the clamping member 222 and the load carrier 221. When the traction frame 21 moves, the load carrier 221 moves along the guide chute 211 towards the cover plate 12, so that the second workpiece 300 abuts against the first workpiece 200 placed on the cover plate 12. The driving member 30 can be a driving device such as a pneumatic cylinder. A plate-shaped, rod-shaped or other structure can be arranged between the driving member 30 and the traction frame 21 to connect them, so that the driving member 30 can drive the traction frame 21 to slide in the accommodating groove 111.

[0028] The assembling jig 100 provided by the embodiment of the application provides a stable basic structure for the assembly of the first workpiece 200 and the second workpiece 300 by arranging the base 10 including the bottom plate 11, the cover plate 12 and the accommodating groove 111 and the movable hole 121. The side of the cover plate 12 away from the bottom plate 11 is used to carry the first workpiece 200, which lays a foundation for subsequent assembly operations. The traction frame 21, the load carrier assembly 22 and the abutting assembly in the first positioning mechanism 20 cooperate with each other to realize accurate clamping and positioning of the second workpiece 300. The driving member 30 drives the traction frame 21 to move, and the traction frame 21 drives the abutting assembly 23 to abut against the clamping member 222, and then the second workpiece 300 is clamped to the clamping member 222 and the load carrier 221, which ensures the position accuracy of the second workpiece 300 in the assembly process and improves the assembly accuracy. When the traction frame 21 moves, the load carrier 221 moves along the guide chute 211 towards the cover plate 12, so that the second workpiece 300 abuts against the first workpiece 200 placed on the cover plate 12, which realizes accurate assembly of the first workpiece 200 and the second workpiece 300 and improves the quality and efficiency of the assembly.

[0029] In some embodiments, please refer to Figure 2 and Figure 3The traction frame 21 is slidably arranged in the accommodating groove 111 along the X-axis direction, the cover plate 12 is provided with a movable hole 121 corresponding to the accommodating groove 111, the load carrier 221 comprises a supporting part 2211 and a load carrying part 2212, the supporting part 2211 is movably arranged in the accommodating groove 111 along the Z-axis direction, the load carrying part 2212 is arranged on the side of the supporting part 2211 opposite to the movable hole 121 and extends out of the movable hole 121, and the load carrying part 2212 is used for carrying the second workpiece 300. The load carrier 221 can be a special-shaped structure, the supporting part 2211 can be a plate-shaped structure, the load carrying part 2212 can be a block-shaped structure, and the side of the load carrying part 2212 used for carrying the second workpiece 300 can be provided with a profiling structure matched with the second workpiece 300, so as to facilitate positioning of the second workpiece 300. It can be understood that the load carrying part 2212 extends out of the movable hole 121, and when the traction member moves along the X-axis direction, the movable hole 121 limits the load carrying part 2212 in the X-axis direction, so that the load carrying part 2212 only moves along the Z-axis direction.

[0030] The guide chute 211 is arranged on the inner side of the side wall of the traction frame 21 along the Y-axis direction, and the upper wall of the guide chute 211 gradually approaches the groove bottom of the accommodating groove 111 along the X-axis direction. The load carrying assembly 22 further comprises a guide column 223, which is arranged on the side of the supporting part 2211 facing the guide chute 211 and movably inserted into the guide chute 211. The guide column 223 corresponds to the guide chute 211, and when the guide chute 211 is provided with two, the guide column 223 is provided with two and is inserted into the two guide chutes 211 respectively.

[0031] In some embodiments, referring to Figure 2 and Figure 3 The load carrying assembly 22 further comprises a plurality of first elastic members 224, which are arranged in the accommodating groove 111. One end of each first elastic member 224 abuts against the groove bottom of the accommodating groove 111, and the other end abuts against the supporting part 2211. The plurality of first elastic members 224 are used for pushing the supporting part 2211 to move away from the groove bottom of the accommodating groove 111.

[0032] The first elastic member 224 can be an elastic structural member such as a spring, and the number of first elastic members 224 can be four, six, eight, etc. By arranging a plurality of first elastic members 224, the supporting part 2211 can be pushed to move along the Z-axis direction, so that the guide column 223 always abuts against the upper side wall of the guide chute 211, i.e. the guide column 223 always abuts against the inclined surface of the guide chute 211. In this way, when the traction member moves along the X-axis direction, the plurality of first elastic members 224 can push the load carrier 221 to move upward along the Z-axis direction along the guide chute 211, so as to make the second workpiece 300 rise to abut against the first workpiece 200.

[0033] In some embodiments, referring to Figure 2 andFigure 3 The carrier assembly 22 further comprises a limiting block 225 and a second elastic member 226. The limiting block 225 is arranged on the side of the supporting part 2211 away from the bottom of the accommodating groove 111 and on the side of the carrier part 2212 away from the driving member 30. The clamping member 222 is slidingly connected to the limiting block 225 along the X-axis direction. The second elastic member 226 is arranged between the clamping member 222 and the carrier part 2212 and is used to push the clamping member 222 away from the carrier part 2212. The limiting block 225 can have a block structure. The limiting block 225 can be provided with dovetail protrusions, T-shaped protrusions or the like extending along the X-axis direction. The clamping member 222 can be provided with corresponding dovetail grooves, T-shaped grooves or the like to slidingly connect the clamping member 222 and the limiting block 225 along the X-axis direction. The limiting block 225 can accurately limit the movement direction of the clamping member 222 and ensure the stable sliding of the clamping member 222 along the X-axis direction, thereby improving the stability and accuracy of the clamping member 222 in clamping the second workpiece 300. The second elastic member 226 can be a spring or other elastic structural member. Two, four or the like second elastic members 226 can be arranged. The second elastic member 226 can drive the clamping member 222 away from the carrier part 2212 to facilitate the loosening of the second workpiece 300 after assembly. The second elastic member 226 can also provide a buffering effect to avoid damage to the second workpiece 300 caused by the clamping member 222 hitting the second workpiece 300.

[0034] In some embodiments, referring to Figure 2 and Figure 3 The limiting block 225 is provided with a limiting pin 227 on the side away from the supporting part 2211. The limiting pin 227 is used to stop the movement of the clamping member 222 away from the carrier part 2212. The limiting pin 227 can have a columnar structure. The limiting pin 227 can stop the clamping member 222 to limit the distance of the clamping member 222 away from the carrier part 2212 under the pushing of the second elastic member 226 and avoid the disengagement of the clamping member 222 from the limiting block 225.

[0035] In some embodiments, referring to Figure 2 and Figure 3The pressing assembly 23 comprises a connecting block 231, a pressing piece 232 and a third elastic piece 233. The connecting block 231 is connected to the upper side of the end of the traction frame 21 away from the driving piece 30. The pressing piece 232 is slidingly inserted into the connecting block 231 along the X-axis direction and abuts against the clamping piece 222. One end of the pressing piece 232 abutting against the clamping piece 222 is provided with a protruding part 2321. The third elastic piece 233 is sleeved on the pressing piece 232, and the two ends of the third elastic piece 233 abut against the connecting block 231 and the protruding part 2321 respectively. The connecting block 231 can be a block structure and is fixedly connected to the traction frame 21. The pressing piece 232 can be a columnar structure and is slidingly connected with the connecting block 231. In order to improve the stability of the pressing clamping piece 222, the number of the pressing piece 232 can be two, four or the like. In order to avoid the pressing piece 232 from falling off the connecting block 231, the two ends of the pressing piece 232 can be provided with the protruding part 2321. The third elastic piece 233 can be a spring or other elastic structure piece. The third elastic piece 233 can press the pressing piece 232 to abut against the clamping piece 222, so as to press the clamping piece 222 to clamp the second workpiece 300 when the traction frame 21 moves along the X-axis direction. By arranging the third elastic piece 233, the pressing piece 232 can be elastically abutted against the clamping piece 222, so as to play a buffering role and avoid leaving a pressing mark or causing other damage on the surface of the second workpiece 300 due to excessive clamping force. Since different batches of second workpieces 300 or the same kind of second workpieces 300 in different processing stages can have differences in size and shape, the pressing assembly with the third elastic piece 233 can make the assembly jig 100 better adapt to these changes.

[0036] In some embodiments, referring to Figure 2 and Figure 3The carrier seat 221 is provided with a plurality of first machining holes 2213 penetrating through the support part 2211 and the carrier part 2212 in the Z-axis direction, and when the second workpiece 300 abuts against the first workpiece 200, the plurality of first machining holes 2213 correspond to the abutting positions of the second workpiece 300 and the first workpiece 200. The bottom plate 11 is provided with a second machining hole 112, which is arranged at the bottom of the accommodating groove 111 and communicates with the accommodating groove 111. The second machining hole 112 communicates with the plurality of first machining holes 2213. The number of first machining holes 2213 can be four, five, six, etc. The plurality of first machining holes 2213 can be arranged in sequence along the Y-axis direction. It can be understood that after the second workpiece 300 abuts against the first workpiece 200, the first workpiece 200 and the second workpiece 300 can be fixed together by laser welding or other methods. At this time, the plurality of first machining holes 2213 correspond to the positions to be welded of the second workpiece 300 and the first workpiece 200, so as to facilitate subsequent machining operations. The area of the second machining hole 112 is greater than the sum of the areas of all the first machining holes 2213. The second machining hole 112 can expose the plurality of first machining holes 2213. In this way, the first workpiece 200 and the second workpiece 300 can be machined through the second machining hole 112 and the first machining hole 2213. In actual operation, the machining device (not shown in the figure, such as a laser welding machine) can be arranged below the assembly jig 100 to process the first workpiece 200 and the second workpiece 300 from bottom to top. This can reduce the step of turning over the assembly jig 100, improve the operation efficiency, and avoid displacement of the first workpiece 200 and the second workpiece 300 when the assembly jig 100 is turned over.

[0037] In some embodiments, referring to Figure 2 and Figure 3 The side of the cover plate 12 away from the bottom plate 11 is also provided with a plurality of inner support blocks 122, which are arranged close to the movable hole 121. The plurality of inner support blocks 122 are used to support the first workpiece 200. The inner support block 122 can be a block structure. The number of inner support blocks 122 can be two, four, six, etc., which are arranged on the upper side of the cover plate 12. The plurality of inner support blocks 122 can provide additional support points for the first workpiece 200, so that the first workpiece 200 is placed more stably on the cover plate 12.

[0038] In some embodiments, referring to Figure 1 and Figure 2The assembly jig 100 further comprises a second positioning mechanism 40, which comprises a movable positioning assembly 41 movably connected with the bottom plate 11 and a plurality of fixed positioning members 42 fixedly connected with the cover plate 12, and the movable positioning assembly 41 is used to push the first workpiece 200 to the plurality of fixed positioning members 42 to position the first workpiece 200. The movable positioning assembly 41 can push the first workpiece 200 to the corresponding fixed positioning members 42, and can accurately position the first workpiece 200 from the X-axis direction and the Y-axis direction, so that the first workpiece 200 can be accurately positioned at a predetermined position before assembly, which lays a good foundation for accurate assembly with the second workpiece 300, and effectively avoids the assembly deviation problem caused by inaccurate position of the first workpiece 200.

[0039] In some embodiments, referring to Figure 1 and Figure 2 , the movable positioning assembly 41 comprises a first sliding plate 411, a second sliding plate 412, a first movable positioning member 413, a second movable positioning member 414, a fourth elastic member 415 and a fifth elastic member 416.

The fifth elastic member 416 is arranged at one side of the second sliding plate 412 away from the first sliding plate 411, and is used to push the second sliding plate 412 to move towards the first sliding plate 411.

[0040] The first sliding plate 411 and the second sliding plate 412 can be plate-shaped structures, the first movable positioning member 413 and the second movable positioning member 414 can be columnar structures, and the fourth elastic member 415 and the fifth elastic member 416 can be elastic structures such as springs. It can be understood that the cover plate 12 can be provided with strip-shaped holes corresponding to the first movable positioning member 413 and the second movable positioning member 414, so that the first movable positioning member 413 and the second movable positioning member 414 can pass through the cover plate 12 and can move in the corresponding strip-shaped holes. The first movable positioning member 413 and the second movable positioning member 414 correspond to two side edges adjacent to the first workpiece 200, and the plurality of fixed positioning members 42 correspond to the other two side edges of the first workpiece 200, respectively.

[0041] When the first workpiece 200 is positioned, the driving member 30 drives the traction frame 21 to move away from the first sliding plate 411 along the X-axis direction, the fourth elastic member 415 pushes the first sliding plate 411 to move along the X-axis direction, the first sliding plate 411 drives the first movable positioning member 413 to push the first workpiece 200 along the X-axis direction to the fixed positioning member 42 opposite to the first movable positioning member 413, and then the first workpiece 200 is positioned in the X-axis direction. During the sliding process of the first sliding plate 411 along the X-axis direction, the pushing groove 4111 on the first sliding plate 411 moves to correspond to the second sliding plate 412, the fifth elastic member 416 pushes the second sliding plate 412 to move along the Y-axis direction, the second sliding plate 412 drives the second movable positioning member 414 to push the second workpiece 300 along the Y-axis direction to the fixed positioning member 42 opposite to the second movable positioning member 414, and then the first workpiece 200 is positioned in the Y-axis direction. In this way, during the movement of the driving member 30 along the X-axis direction, the first movable positioning member 413 and the second movable positioning member 414 cooperate with the plurality of fixed positioning members 42 to position the first workpiece 200 in the X-Y plane.

[0042] In the embodiment, when the driving member 30 drives the traction frame 21 to move along the X-axis direction to the maximum distance, the traction frame 21 is spaced apart from the first sliding plate 411, so that the second positioning mechanism 40 can complete the positioning of the first workpiece 200 before the first positioning mechanism 20 moves the second workpiece 300 along the Z-axis direction to the highest position (i.e., the position where the second workpiece 300 abuts against the first workpiece 200), thereby avoiding the poor assembly caused by the incomplete positioning of the first workpiece 200 when the second workpiece 300 abuts against the first workpiece 200.

[0043] When the first workpiece 200 is loosened, the driving member 30 drives the traction frame 21 to move towards the first sliding plate 411, the traction frame 21 pushes the first sliding plate 411 to move in the opposite direction of the X-axis direction, and then drives the first movable positioning member 413 to move away from the first workpiece 200. When the first sliding plate 411 moves in the opposite direction of the X-axis direction, the inclined surface of the abutting groove 4111 pushes the second sliding plate 412 to move in the opposite direction of the Y-axis direction, and then drives the second movable positioning member 414 to move away from the first workpiece 200, so that the first workpiece 200 can be loosened.

[0044] In some embodiments, referring to Figure 1 and Figure 2 , the bottom plate 11 is provided with a first sliding groove 113 and a second sliding groove 114 on the side close to the cover plate 12, the first sliding groove 113 extends along the X-axis direction and communicates with the accommodating groove 111, the first sliding plate 411 is slidingly arranged in the first sliding groove 113, the fourth elastic member 415 is arranged in the first sliding groove 113 and the two ends thereof abut against one end of the first sliding plate 411 away from the traction frame 21 and the groove wall of the first sliding groove 113 away from the accommodating groove 111, the second sliding groove 114 extends along the Y-axis direction and communicates with the first sliding groove 113, the second sliding plate 412 is slidingly arranged in the second sliding groove 114, and the fifth elastic member 416 is arranged in the second sliding groove 114 and the two ends thereof abut against one end of the second sliding plate 412 away from the first sliding plate 411 and the groove wall of the second sliding groove 114 away from the first sliding groove 113. By arranging the first sliding groove 113, the movement of the first sliding plate 411 in the X-axis direction can be limited in the first sliding groove 113, ensuring the straightness of the movement of the first sliding plate 411, and when the traction frame 21 or the fourth elastic member 415 pushes the first sliding plate 411 to move, the first sliding groove 113 can prevent the first sliding plate 411 from deviating, thereby ensuring the movement accuracy of the first movable positioning member 413 in the X-axis direction. By arranging the second sliding groove 114, the movement of the second sliding plate 412 in the Y-axis direction can also be accurately guided, thereby ensuring the movement accuracy of the second movable positioning member 414 in the Y-axis direction.

[0045] In some embodiments, referring to Figure 1 and Figure 2The first movable positioning member 413 is provided with a first protrusion 4131 at one end away from the first sliding plate 411, and the first protrusion 4131 is arranged on the side of the first movable positioning member 413 facing the driving member 30. The second movable positioning member 414 is provided with a second protrusion 4141 at one end away from the second sliding plate 412, and the second protrusion 4141 is arranged on the side of the second movable positioning member 414 facing the first sliding plate 411. The first protrusion 4131 and the second protrusion 4141 are used for clamping the first workpiece 200 to position the first workpiece 200 in the Z-axis direction. By arranging the first protrusion 4131 on the first movable positioning member 413 and the second protrusion 4141 on the second movable positioning member 414, the first protrusion 4131 and the second protrusion 4141 can clamp the first workpiece 200 when the first movable positioning member 413 and the second movable positioning member 414 abut against the first workpiece 200, so as to position the workpiece in the Z-axis direction, and avoid the first workpiece 200 from moving upward when the second workpiece 300 abuts against the first workpiece 200. It can be understood that the side of the fixed positioning member 42 abutting against the first workpiece 200 can also be provided with a protrusion structure to position the first workpiece 200 in the Z-axis direction.

[0046] The working process of the assembly jig 100 provided by the embodiment of the present application is as follows:

[0047] Firstly, the second workpiece 300 is placed on the loading part 2212 of the loading seat 221, and then the first workpiece 200 is placed on the cover plate 12.

[0048] Then, the driving member 30 drives the traction frame 21 to move in the X-axis direction, the fourth elastic member 415 pushes the first sliding plate 411 to move in the X-axis direction, the first sliding plate 411 drives the first movable positioning member 413 to push the first workpiece 200 in the X-axis direction to the fixed positioning member 42 opposite to the first movable positioning member 413, so as to position the first workpiece 200 in the X-axis direction. During the sliding process of the first sliding plate 411 in the X-axis direction, the pushing groove 4111 on the first sliding plate 411 moves to correspond to the second sliding plate 412, the fifth elastic member 416 pushes the second sliding plate 412 to move in the Y-axis direction, the second sliding plate 412 drives the second movable positioning member 414 to push the second workpiece 300 in the Y-axis direction to the fixed positioning member 42 opposite to the second movable positioning member 414, so as to position the first workpiece 200 in the Y-axis direction.

[0049] When the traction frame 21 moves along the X-axis direction, the guide chute 211 on the traction frame 21 moves synchronously along the X-axis direction, the guide column 223 on the carrier seat 221 slides along the guide chute 211, the first elastic member 224 pushes the carrier seat 221 to move upward, and then drives the second workpiece 300 to move toward the first workpiece 200. At the same time, the traction frame 21 drives the pushing assembly to move, the pushing assembly pushes the clamping member 222 to move along the X-axis direction, so that the clamping member 222 clamps the second workpiece 300 in cooperation with the carrier part 2212. When the carrier seat 221 moves away from the bottom plate 11 to the farthest distance, the second workpiece 300 abuts against the first workpiece 200, and precise assembly is realized.
