The plurality of first positioning pins 21 are uniformly arranged on the middle plate 12, and the specific position of each first positioning pin 21 corresponds to the first positioning hole 2001 on the first workpiece 2000. After the first positioning pin 21 is inserted into the first positioning hole 2001 of the first workpiece 2000, the middle part of the first workpiece 2000 is erected on the first through slot 121.

[0031] The assembly assembly 30 comprises a sliding piece 31, a first fixing piece 32, a first elastic piece 33 and a plurality of pairs of second positioning pins 34, the sliding piece 31 is slidingly arranged in the first through slot 121, the first fixing piece 32 is fixedly connected to the bottom plate 11 and arranged opposite to the sliding piece 31, the first elastic piece 33 is arranged between the sliding piece 31 and the first fixing piece 32, and is used for pushing the sliding piece 31 away from the first fixing piece 32, each pair of second positioning pins 34 is connected to the sliding piece 31 and extends into the discharging through hole 131, the plurality of pairs of second positioning pins 34 are arranged one by one corresponding to the plurality of pairs of first positioning pins 21, and each pair of second positioning pins 34 is arranged on the side of the corresponding pair of first positioning pins 21 close to the first fixing piece 32, and the end of each second positioning pin 34 extending out of the sliding piece 31 is arranged in the discharging through hole 131.

[0032] The sliding piece 31 can be a strip-shaped structure and can slide along the first through slot 121. It can be understood that in order to increase the number of assembled first workpieces 2000 and second workpieces 3000, the first through slot 121 and the sliding piece 31 can be provided with multiple, such as two, three, etc. The ends of the plurality of sliding pieces 31 away from the first fixing piece 32 can be fixedly connected by plates, blocks or the like structure to enable the plurality of sliding pieces 31 to move synchronously. The first fixing piece 32 can be a block-shaped structure, and when the sliding piece 31 is provided with multiple, the first fixing piece 32 corresponds to the sliding piece 31. The first elastic piece 33 can be a spring or other elastic structure, and the number and position of the first elastic piece 33 correspond to the sliding piece 31. It can be understood that in order to avoid the first elastic piece 33 from pushing the sliding piece 31 to move excessively, the end of the sliding piece 31 abutting against the first elastic piece 33 can be provided with a protrusion, which can abut against the middle plate 12 to limit the sliding piece 31. The second positioning pin 34 can be provided with four pairs, eight pairs, ten pairs, etc., and the number and position of the second positioning pin 34 correspond to the first positioning pin 21.

[0033] Wherein, each pair of first positioning pins 21 is used for positioning the first workpiece 2000, the sliding piece 31 moves towards the first fixed piece 32 under the action of external force, so that the first elastic piece 33 is elastically compressed and drives each pair of second positioning pins 34 to be elastically away from the corresponding first positioning pin 21, so that the two ends of the first workpiece 2000 are respectively installed on a pair of first positioning pins 21, and the second workpiece 3000 is installed on the second positioning pin 34; after the external force is removed, the first elastic piece 33 is elastically reset to push the sliding piece 31 to move away from the first fixed piece 32, so as to drive the second workpiece 3000 on the second positioning pin 34 to move towards the first workpiece 2000 of the first positioning pin 21, and then the second workpiece 3000 is assembled to the first workpiece 2000. In actual operation, the first workpiece 2000 can be positioned through the first positioning pin 21, and then the sliding piece 31 is pushed towards the first fixed piece 32 manually or by a cylinder or other driving device, so that the second positioning pin 34 is away from the corresponding first positioning pin 21, and then the second workpiece 3000 is installed on the second positioning pin 34. Then the sliding piece 31 is loosened, the first elastic piece 33 can push the sliding piece 31 to move, and then the second workpiece 3000 is assembled to the first workpiece 2000.

[0034] The assembly jig 100 provided by the embodiment of the application provides a stable and accurate operation platform for assembly through the bearing assembly 10, and each pair of first positioning pins 21 in the positioning assembly 20 is arranged on the middle plate 12 and opposite to the feeding through hole 131, so that the first workpiece 2000 can be placed on the first positioning pin 21 through the feeding through hole 131, so that the first positioning pin 21 positions the first workpiece 2000. The sliding piece 31 of the assembly assembly 30 can move towards the first fixed piece 32 under the action of external force, so that the first elastic piece 33 is elastically compressed and drives the second positioning pin 34 to be away from the corresponding first positioning pin 21, and then the second workpiece 3000 is placed on the second positioning pin 34 and positioned by the second positioning pin 34. After the external force is removed, the first elastic piece 33 is elastically reset to push the sliding piece 31 to move away from the first fixed piece 32, the sliding piece 31 drives the second workpiece 3000 to move towards the first workpiece 2000 through the second positioning pin 34, and then the first workpiece 2000 and the second workpiece 3000 are assembled together. The assembly jig 100 provided by the embodiment of the application can accurately position the first workpiece 2000 and the second workpiece 3000, and improve the assembly accuracy.

[0035] In some embodiments, please refer to Figure 1 、 Figure 2 and Figure 4A second through groove 111 is provided on the side of the base plate 11 facing the middle plate 12. The second through groove 111 is located below the first through groove 121. Each first positioning pin 21 is slidably connected to the middle plate 12, and each first positioning pin 21 has an abutment protrusion 211 at its end facing the base plate 11. The width of the second through groove 111 is greater than the width of the first through groove 121. In this embodiment, there can be multiple second through grooves 111, and their number and position correspond to the first through grooves 121. The first positioning pins 21 are slidably connected to the middle plate 12 in the vertical direction, and the abutment protrusions 211 can be spherical.

[0036] The positioning component 20 also includes a retractable pin 22, multiple second elastic elements 23, a second fixing element 24, and a third elastic element 25.

[0037] The retractable pin 22 is slidably disposed in the second through groove 111. The retractable pin 22 has multiple pairs of inclined grooves 221 with inclined sidewalls 2211, and each pair of inclined grooves 221 corresponds to each pair of first positioning pins 21. The retractable pin 22 can be a strip structure, and the number of retractable pins 22 is consistent with the number of second through grooves 111. When multiple retractable pins 22 are provided, the ends of multiple retractable pins 22 away from the second fixing member 24 can be fixedly connected by strip-shaped or block-shaped structures so that multiple retractable pins 22 can move synchronously. The number and position of the inclined grooves 221 on the retractable pin 22 correspond to the first positioning pins 21, and the end of each inclined groove 221 near the second fixing member 24 is higher than the end away from the second fixing member 24.

[0038] Multiple second elastic elements 23 are respectively sleeved on the first positioning pin 21. One end of the second elastic element 23 is inserted into the middle plate 12, and the other end abuts against the abutment protrusion 211 to push the first positioning pin 21 toward the inclined groove 221, so that the abutment protrusion 211 abuts against the inclined groove 221. The second elastic element 23 can be an elastic structural component such as a spring. The number of second elastic elements 23 is the same as the number of first positioning pins 21. The middle plate 12 can also have a groove structure to accommodate the second elastic elements 23.

[0039] The second fastener 24 is fixedly connected to the side of the base plate 11 away from the first fastener 32, and the second fastener 24 is disposed opposite to the retracting pin 22. The second fastener 24 can be a block structure, and when there are multiple retracting pins 22, the second fastener 24 corresponds to each retracting pin 22.

[0040] The third elastic element 25 is disposed between the second fixing element 24 and the retracting pin 22, with its two ends abutting against the second fixing element 24 and the retracting pin 22, respectively. The third elastic element 25 can be an elastic structural element such as a spring, and multiple third elastic elements 25 can be provided, with their number and position corresponding to the retracting pin 22.

[0041] The retracting pin 22 is used to move the inclined groove 221 downwards from the first positioning pin 21 under the action of external force, thereby compressing the third elastic element 25 and causing the second elastic element 23 to push the first positioning pin 21 along the top of the inclined groove 221 and slide into the bottom along the inclined side wall 2211, thereby causing the first positioning pin 21 to retract into the middle plate 12 to release the first workpiece 2000; and when the external force on the retracting pin 22 is removed, the third elastic element 25 elastically resets and pushes the retracting pin 22 away from the second fixing element 24, so that the inclined side wall 2211 of the inclined groove 221 pushes the first positioning pin 21 away from the retracting pin 22, thereby causing the first positioning pin 21 to extend out of the middle plate 12. Thus, after the first workpiece 2000 and the second workpiece 3000 are assembled, the pusher 402 can be driven to move toward the second fixing member 24 by manual or cylinder drive mechanism. The second elastic member 23 pushes the abutment protrusion 211 of the first positioning pin 21 and moves along the inclined side wall 2211 of the inclined groove 221, thereby causing the first positioning pin 21 to retract into the middle plate 12, which facilitates the unloading of the first workpiece 2000.

[0042] In some embodiments, see Figure 1 and Figure 2 The first fixing member 32 has a limiting hole 321, and the positioning assembly 20 also includes a limiting pin 26. The limiting pin 26 is connected to the end of the retracting pin 22 away from the second fixing member 24, and the end of the limiting pin 26 away from the retracting pin 22 is movably disposed in the limiting hole 321. In this way, through the cooperation of the limiting pin 26 and the limiting hole 321, the movement distance of the retracting pin 22 can be limited, avoiding excessive movement of the retracting pin 22 that could cause misalignment between the first positioning pin 21 and the inclined groove 221.

[0043] In some embodiments, see Figure 1 , Figure 2 and Figure 5 The sliding member 31 has multiple receiving grooves 311 with openings facing the bottom of the first through groove 121. Each receiving groove 311 corresponds one-to-one with each pair of second positioning pins 34, and each second positioning pin 34 is movably inserted through the bottom of the receiving groove 311. The assembly component 30 also includes multiple fourth elastic members 35, each fourth elastic member 35 is respectively disposed in one receiving groove 311, and one end of the fourth elastic member 35 is connected to the corresponding second positioning pin 34, while the other end abuts against the bottom of the first through groove 121. The fourth elastic member 35 can be an elastic structural member such as a spring. The opposite ends of each pair of second positioning pins 34 and the fourth elastic member 35 can be connected by a sheet-like structure to enable the two second positioning pins 34 to move synchronously and improve the stability of the second positioning pins 34. The fourth elastic member 35 can float to support the second positioning pins 34. In this way, when installing or removing the second workpiece 3000, rigid contact between the second workpiece 3000 and the second elastic member 23 can be avoided, which could damage the second workpiece 3000.

[0044] In some embodiments, see Figure 1 , Figure 2 and Figure 3 The assembly component 30 also includes multiple support blocks 36, each positioned on the side of the sliding member 31 near the cover plate 13. Each support block 36 is also positioned on the side of each pair of second positioning pins 34 near the corresponding first positioning pin 21. The support blocks 36 support the second workpiece 3000. This design prevents the second workpiece 3000 from falling vertically towards the first workpiece 2000, which would affect its assembly with the first workpiece 2000. The support blocks 36 can be irregularly shaped to fit the structure of the second workpiece 3000, further improving support stability.

[0045] The general working process of the assembly fixture 100 provided in this embodiment is as follows:

[0046] First, multiple first workpieces 2000 are respectively installed on each pair of first positioning pins 21 located in the discharge through hole 131. Then, the sliding member 31 is driven by external force to move towards the first fixing member 32, so that the first elastic member 33 is elastically compressed and the second positioning pin 34 moves away from the corresponding first positioning pin 21. Next, the second workpiece 3000 is installed on each pair of corresponding second positioning pins 34. Then, the sliding member 31 is released, and the first elastic member 33 elastically resets and pushes the sliding member 31 away from the first fixing member 32. The sliding member 31 drives the second positioning pin 34 and the second workpiece 3000 to move towards the corresponding first workpiece 2000, thereby assembling the first workpiece 2000 and the second workpiece 3000 together.

[0047] During unloading, the external force drives the retracting pin 22 to move the inclined groove 221 downwards towards the first positioning pin 21, thereby compressing the third elastic element 25 and causing the second elastic element 23 to push the first positioning pin 21 along the top of the inclined groove 221 into the bottom, thereby causing the first positioning pin 21 to retract into the middle plate 12 and the first positioning pin 21 to detach from the first workpiece 2000, facilitating unloading.

[0048] This application embodiment also provides an assembly device 1000 for assembling a first workpiece 2000 and a second workpiece 3000. The first workpiece 2000 and the second workpiece 3000 are as described above and will not be repeated here. The assembly device 1000 includes the above-mentioned assembly fixture 100, support frame 200, lifting mechanism 300, and pushing mechanism 400.

[0049] The support frame 200 includes a limiting plate 201, which has a material feeding window 2011. The support frame 200 also includes a support plate 202 for supporting the limiting plate 201. The limiting plate 201 is arranged in a horizontal direction, and the structure of the material feeding window 2011 is adapted to the assembly fixture 100.

[0050] The lifting mechanism 300 is located below the limiting plate 201 and opposite to the discharge window 2011. The lifting mechanism 300 is used to carry and lift the assembly fixture 100 to the limiting plate 201.

[0051] The push mechanism 400 is connected to the limiting plate 201 and is located near the feeding window 2011. When the assembly fixture 100 abuts against the limiting plate 201, the end of the sliding member 31 away from the first fixing member 32 is opposite to the push mechanism 400. The push mechanism 400 is used to push the sliding member 31 toward the first fixing member 32 so that the second positioning pin 34 is away from the corresponding first positioning pin 21.

[0052] When assembling the first workpiece 2000 and the second workpiece 3000, the first workpiece 2000 can be placed on the assembly fixture 100 first, and then the assembly fixture 100 can be mounted on the lifting mechanism 300. The lifting mechanism 300 lifts the assembly fixture 100 to the limit plate 201. It can be understood that the material discharge window 2011 exposes the material discharge through hole 131 of the assembly fixture 100. Then, the pushing mechanism 400 pushes the sliding member 31 to move, so that the first elastic member 33 is elastically compressed and the second positioning pin 34 moves away from the corresponding first positioning pin 21. Then, the second workpiece 3000 is placed on the second positioning pin 34. After the second workpiece 3000 is placed, the pushing mechanism 400 releases the sliding member 31. Under the pushing action of the elastic return of the first elastic member 33, the sliding member 31 drives the second workpiece 3000 toward the first workpiece 2000, thereby completing the assembly. After the assembly is completed, the lifting mechanism 300 moves the assembly fixture 100 down, so that the assembly fixture 100 can be removed, and then the material can be unloaded.

[0053] Please see Figure 1 , Figure 6 and Figure 7 The assembly equipment 1000 provided in this application embodiment can carry and lift the assembly fixture 100 to the limiting plate 201 via the lifting mechanism 300. The pushing mechanism 400 can push the sliding member 31 of the assembly fixture 100 towards the first fixing member 32, thereby causing the first elastic member 33 to elastically compress and the second positioning pin 34 to move away from the corresponding first positioning pin 21. After the first workpiece 2000 and the second workpiece 3000 are placed, the pushing mechanism 400 releases the sliding member 31, the first elastic member 33 elastically resets, and pushes the sliding member 31 away from the first fixing member 32. The sliding member 31, through the second positioning pin 34, drives the second workpiece 3000 towards the first workpiece 2000, thereby assembling the first workpiece 2000 and the second workpiece 3000 together. The assembly equipment 1000 provided in this application embodiment can automatically assemble the first workpiece 2000 and the second workpiece 3000, reducing labor intensity and improving work efficiency.

[0054] In some embodiments, seeFigure 1 , Figure 6 and Figure 7 The assembly equipment 1000 also includes a pressing mechanism 500, which includes a displacement drive component 501, a pressing drive component 502, and a pressing component 503.

[0055] The displacement drive 501 is connected to the side of the limiting plate 201 opposite to the lifting mechanism 300 and is located near the discharge window 2011. The holding drive 502 is connected to the displacement drive 501, and the holding member 503 is connected to the holding drive 502. The displacement drive 501 drives the holding drive 502 towards the discharge window 2011, and the holding drive 502 drives the holding member 503 towards the assembly fixture 100, so that the holding member 503 abuts against the first positioning pin 21 and the second positioning pin 34.

[0056] Both the displacement drive 501 and the holding drive 502 can be drive components such as cylinders. The holding member 503 can be a plate-like structure. When the assembly fixture 100 is provided with multiple rows of first positioning pins 21 and second positioning pins 34, the holding member 503 is provided with multiple contact ends 5031 on the side facing the assembly fixture 100. After the second workpiece 3000 is placed on the second positioning pin 34 and before the push mechanism 400 releases the sliding member 31, the displacement drive 501 drives the holding drive 502 to move above the assembly fixture 100, and the holding drive 502 drives the holding member 503 to move toward the assembly fixture 100 so that the holding member 503 abuts against the first positioning pin 21 and the second positioning pin 34, preventing the first workpiece 2000 and the second workpiece 3000 from detaching from the first positioning pin 21 or the second positioning pin 34 during the assembly process.

[0057] In some embodiments, see Figure 1 , Figure 6 and Figure 7 The assembly equipment 1000 also includes a detection mechanism 600, which is located near the support frame 200. The detection mechanism 600 is used to detect the first workpiece 2000 and the second workpiece 3000. The detection mechanism 600 includes a camera 601, an aperture 602, and other mechanisms. It is understood that, to improve automation, a robot (not shown) can be used for loading. The robot can simultaneously grasp multiple first workpieces 2000 or second workpieces 3000. Before loading, the robot can move the first workpiece 2000 or second workpiece 3000 to the detection mechanism 600 to obtain the offset value between the first workpiece 2000 or second workpiece 3000 and the standard position. During loading, the robot automatically performs position compensation to improve loading accuracy. Simultaneously, the detection mechanism 600 can also be used to acquire images of the first workpiece 2000 or second workpiece 3000 and compare them with standard images to determine whether the first workpiece 2000 or second workpiece 3000 is qualified.

[0058] In some embodiments, see Figure 1 , Figure 6 and Figure 7 The pushing mechanism 400 includes a pushing drive member 401 connected to the limiting plate 201 and a pushing member 402 connected to the pushing drive member 401. The end of the pushing member 402 away from the pushing drive member 401 is movably disposed on the side of the limiting plate 201 facing the lifting mechanism 300. The pushing drive member 401 is used to drive the pushing member 402 to move closer to or away from the sliding member 31 of the assembly fixture 100. The pushing drive member 401 can be a driving device such as a cylinder, and the pushing member 402 can be a plate-shaped structure.

[0059] In some embodiments, see Figure 1 , Figure 6 and Figure 7 The lifting mechanism 300 includes a lifting drive component 301, a support component 302, and an adsorption component 303. The support component 302 is connected to the lifting drive component 301. The adsorption component 303 is disposed on one side of the support component 302 for supporting the assembly fixture 100 and is used to adsorb the base plate 11. The lifting drive component 301 can be a cylinder or other driving component, and the support component 302 can be a U-shaped structure. The adsorption component 303 can be a magnet or other magnetic component. Multiple adsorption components 303, such as two, three, or four, can be disposed on the support component 302 to improve the stability of the adsorption base plate 11. It is understood that the base plate 11 can be made of magnetic material, such as magnetic stainless steel, or magnetic components can be disposed at positions corresponding to the adsorption components 303 on the base plate 11 so that the adsorption components 303 can adsorb the base plate 11.

[0060] A positioning part 2012 is provided on the side of the limiting plate 201 facing the lifting mechanism 300. The base plate 11 of the assembly fixture 100 is also provided with a positioning through hole 112 that matches the positioning part 2012. The positioning part 2012 cooperates with the positioning through hole 112 to position the assembly fixture 100 when it abuts against the limiting plate 201. The positioning part 2012 can be a columnar mechanism. Through the cooperation of the positioning part 2012 and the positioning through hole 112, the positional accuracy of the assembly fixture 100 when it abuts against the limiting plate 201 can be improved.

[0061] The working process of the assembly equipment 1000 provided in this application embodiment is roughly as follows:

[0062] First, the first workpiece 2000 can be placed on the assembly fixture 100 by an external feeding device (not shown), and the first workpiece 2000 can be positioned by the first positioning pin 21. Then, the assembly fixture 100 is placed on the carrier 302 of the lifting mechanism 300, and the bottom plate 11 is adsorbed by the adsorption member 303, thereby initially positioning the assembly fixture 100 to ensure that its placement position is accurate.

[0063] Then, the lifting drive 301 drives the carrier 302 to rise, lifting the assembly fixture 100 toward the limiting plate 201 of the support frame 200. When the assembly fixture 100 comes into contact with the limiting plate 201, the positioning part 2012 provided on the side of the limiting plate 201 facing the lifting mechanism 300 cooperates with the corresponding positioning through hole 112 on the bottom plate 11 of the assembly fixture 100 to further accurately position the assembly fixture 100.

[0064] After the assembly fixture 100 is in place, the push-pull drive 401 in the push-pull mechanism 400 drives the push-pull component 402 to move. Since the end of the push-pull component 402 away from the push-pull drive 401 is movably positioned on the side of the limiting plate 201 facing the lifting mechanism 300, and when the assembly fixture 100 abuts against the limiting plate 201, the end of the sliding component 31 away from the first fixing component 32 is opposite to the push-pull mechanism 400. The push-pull component 402 pushes the sliding component 31 of the assembly fixture 100 toward the first fixing component 32, so that the first elastic component 33 is elastically compressed and each pair of second positioning pins 34 moves away from the corresponding first positioning pin 21.

[0065] Next, the second workpiece 3000 is placed on the assembly fixture 100 via an external feeding device, and positioned by the second positioning pin 34. The displacement drive 501 in the holding mechanism 500 drives the holding drive 502 to move above the assembly fixture 100, and the holding drive 502 drives the holding member 503 to move towards the assembly fixture 100, so that the holding member 503 abuts against the first positioning pin 21 and the second positioning pin 34, preventing the first workpiece 2000 and the second workpiece 3000 from detaching from the first positioning pin 21 or the second positioning pin 34 during assembly.

[0066] Then, the sales mechanism 400 removes the external force applied to the sliding member 31, and the first elastic member 33 elastically resets and pushes the sliding member 31 away from the first fixed member 32, thereby driving the second workpiece 3000 to move toward the first workpiece 2000, and finally realizing the assembly operation of the first workpiece 2000 and the second workpiece 3000.

[0067] Finally, the holding mechanism 500 resets, and the lifting drive 301 drives the assembly fixture 100 away from the limiting plate 201 via the carrier 302, so that the assembly fixture 100 can be removed from the carrier 302. After the assembly fixture 100 is removed, the external force drives the retracting pin 22 to move the inclined groove 221 downwards from the first positioning pin 21, thereby compressing the third elastic element 25 and causing the second elastic element 23 to push the first positioning pin 21 along the top of the inclined groove 221 and slide it into the bottom along the inclined side wall 2211, thereby causing the first positioning pin 21 to retract into the middle plate 12 and the first positioning pin 21 to detach from the first workpiece 2000, facilitating unloading.
