[0071] like Figures 1 to 27 As shown, this application provides an automatic keychain assembly equipment 100 for assembling a keychain 101 from a keychain body 102, a keycap 103, a torsion spring 104, a pin, and a buckle 106. The automatic keychain assembly equipment 100 includes a frame 10, a turntable 11, and a clamping fixture 12 disposed on the turntable 11. The frame 10 is equipped with a keychain body acquisition mechanism 20, a keycap acquisition mechanism 30, a torsion spring acquisition mechanism 40, a pin acquisition mechanism 50, a buckle acquisition mechanism 70, a pin riveting mechanism 60, a buckle fixing mechanism 80, and a finished product picking mechanism 90. The buckle body acquiring mechanism 20 is used to acquire the buckle body 102; the buckle head acquiring mechanism 30 is used to acquire the buckle head 103; the torsion spring acquiring mechanism 40 is used to acquire the torsion spring 104; the pin acquiring mechanism 50 is used to acquire the pin; the buckle ring acquiring mechanism 70 is used to acquire the buckle ring 106; the pin riveting mechanism 60 is used to rivet the pin so that the pin can rotate and attach the buckle head 103 to the buckle body 102; the buckle ring fixing mechanism 80 is used to assemble and fix the buckle ring 106 to the buckle body 102; the automatic keychain assembly equipment 100 accurately assembles the buckle body 102, buckle head 103, torsion spring 104, pin, and buckle ring 106 into a keychain 101, realizing the automated assembly of the keychain 101 and improving the assembly efficiency of the keychain 101. Multiple clamping fixtures 12 are used.

[0072] In this embodiment, as Figure 2 As shown, the buckle body 102 has a buckle opening 1021 and a buckle pin hole; the buckle head 103 has a buckle pin hole 1031, and a pin is riveted and fixed in the buckle pin hole and the buckle pin hole 1031 so that the buckle head 103 is rotatably attached to the buckle body 102 by the pin, and the buckle head 103 can open or close the buckle opening 1021 during the rotation process; the torsion spring 104 is disposed between the buckle head 103 and the buckle body 102 so as to drive the buckle head 103 to be in the closed buckle opening 1021 state; the buckle ring 106 has a buckle ring connecting hole 1061, which is sleeved on the outside of the buckle body pivot portion 1022 of the buckle body 102 so as to allow the buckle ring 106 to rotate relative to the buckle body 102.

[0073] In this embodiment, as Figure 1As shown, the frame 10 serves as the support structure for the equipment, supporting and securing other components to ensure the stability and reliability of the entire device. The structure of the frame 10 is not strictly limited; it only needs to support the turntable 11, the buckle acquisition mechanism 20, the buckle head acquisition mechanism 30, the torsion spring acquisition mechanism 40, the pin acquisition mechanism 50, the buckle ring acquisition mechanism 70, the pin riveting mechanism 60, the buckle ring fixing mechanism 80, and the finished product handling mechanism 90, etc., which will not be further elaborated here. For example, the frame 10 can be a frame structure. The bottom of the frame 10 is equipped with casters to facilitate the movement of the entire key fob automatic assembly equipment 100.

[0074] In this embodiment, as Figures 1 to 2 As shown, the turntable 11 is configured to rotate about a fixed axis and is mounted on the frame 10; the rotation of the turntable 11 enables assembly line operation and improves assembly efficiency. In operation, the turntable 11 rotates about a vertical axis in the automatic keychain assembly equipment 100. The automatic keychain assembly equipment 100 also includes a motor for driving the turntable 11. Multiple clamping fixtures 12 are arranged circumferentially around the turntable 11.

[0075] In this embodiment, as Figures 1 to 2 As shown, the buckle body acquisition mechanism 20, buckle head acquisition mechanism 30, torsion spring acquisition mechanism 40, pin acquisition mechanism 50, buckle ring acquisition mechanism 70, pin riveting mechanism 60, buckle ring fixing mechanism 80, and finished product picking mechanism 90 are arranged at intervals around the outer periphery of the turntable 11. During rotation, the turntable 11 drives the clamping fixture 12, giving it multiple workstations. Each workstation corresponds to one of the buckle body acquisition mechanism 20, buckle head acquisition mechanism 30, torsion spring acquisition mechanism 40, pin acquisition mechanism 50, buckle ring acquisition mechanism 70, pin riveting mechanism 60, buckle ring fixing mechanism 80, or finished product picking mechanism 90.

[0076] In this embodiment, as Figures 1 to 2As shown, the clamping fixture 12 is fixed to the turntable 11. The clamping fixture 12 is used to support and position the various components of the keychain 101, ensuring stability and accuracy during assembly. The number of clamping fixtures 12 is not strictly required and can be adjusted according to actual needs, which will not be further elaborated here. For example, there can be eight clamping fixtures 12, which can correspond to the buckle body acquisition mechanism 20, buckle head acquisition mechanism 30, torsion spring acquisition mechanism 40, pin acquisition mechanism 50, buckle ring acquisition mechanism 70, pin riveting mechanism 60, buckle ring fixing mechanism 80, and finished product picking mechanism 90, respectively. This allows the buckle body acquisition mechanism 20, buckle head acquisition mechanism 30, torsion spring acquisition mechanism 40, pin acquisition mechanism 50, buckle ring acquisition mechanism 70, pin riveting mechanism 60, buckle ring fixing mechanism 80, and finished product picking mechanism 90 to work synchronously, thereby improving the working efficiency of the automatic keychain assembly equipment 100. Of course, the number of clamping jigs 12 can also be greater than 8; for example, 9, 10, 11, 12, 13, 14, 15 or 16.

[0077] In this embodiment, as Figure 3 , Figure 12 , Figure 13 , Figure 20 , Figure 21 as well as Figure 22 As shown, the clamping fixture 12 includes a base 121, which is fixed to the turntable 11. The base 121 can be fixed to the turntable 11 by welding or bolts. The shape of the base 121 is not strictly limited; for example, the base 121 is generally a block structure.

[0078] In this embodiment, as Figure 1 and Figure 3 As shown, the base 121 has a buckle body 102 placement slot; the buckle body acquisition mechanism 20 is capable of placing the buckle body 102 into the buckle body 102 placement slot. The buckle body acquisition mechanism 20 includes a buckle body placement device 21 and a buckle body transfer device 22. The buckle body placement device 21 is configured to place the buckle body 102 into an ordered state, and the buckle body transfer device 22 is configured to transfer the buckle body 102 in the ordered state into the placement slot.

[0079] In this embodiment, as Figure 3As shown, the buckle placement device 21 includes a buckle vibratory feeder 211 and a buckle conveyor line 212. The buckle vibratory feeder 211 conveys the buckles 102 to the buckle conveyor line 212 to organize the scattered buckles 102 into an orderly state, facilitating subsequent operations. The buckle transfer device 22 includes a buckle gripper 221. The turntable 11 drives the clamping fixture 12 to rotate to the buckle acquisition mechanism 20; the buckle gripper 221 is used to place the buckles 102 conveyed by the buckle conveyor line 212 into the placement slot of the clamping fixture 12, so as to achieve the effect of automatically transferring the buckles 102 onto the clamping fixture 12. The buckle vibratory feeder 211, the buckle conveyor line 212, and the buckle gripper 221 can all adopt existing technologies, and will not be further described here.

[0080] In this embodiment, as Figures 4 to 14 As shown, the clamping fixture 12 also includes a buckle pushing member 122 and a buckle limiting member 123. The buckle pushing member 122 is movably coupled to the base 121 and has a third position and a fourth position. The buckle limiting member 123 is movably coupled to the base 121 via a buckle elastic member 124. The buckle limiting member 123 is configured to be driven by the buckle elastic member 124 to limit the buckle pushing member 122 to the third position or the fourth position. When the buckle pushing member 122 is in the third position, the buckle acquiring mechanism 30 moves the buckle 103 to the base 121 or the buckle pushing member 122. Then, the buckle pushing member 122 drives the buckle 103 until the buckle pushing member 122 moves to the fourth position, so that the buckle 103 is assembled onto the buckle body 102 located on the base 121, thereby achieving the effect of automatic assembly of the buckle 103.

[0081] In this embodiment, as Figures 12 to 13 As shown, the structure of the buckle pushing member 122 is not strictly limited, as long as the buckle pushing member 122 can push the buckle 103 to move; for example, the buckle pushing member 122 has a block structure. When the buckle 103 is placed on the clamping fixture 12: the buckle 103 can be placed on the base 121 or on the buckle pushing member 122. The base 121 is provided with a first sliding groove, and the buckle pushing member 122 can slide along the first sliding groove to limit the movement path of the buckle pushing member 122.

[0082] In this embodiment, as Figures 12 to 13As shown, the buckle pushing member 122 has a buckle positioning part 1221 for positioning the buckle 103. When the buckle acquiring mechanism 30 places the buckle 103 on the buckle pushing member 122, the buckle positioning part 1221 can position the buckle 103, ensuring accurate alignment between the buckle 103 and the buckle body 102 during assembly, further improving the assembly quality and efficiency of the buckle 103. The buckle positioning part 1221 is a groove structure; a portion of the buckle 103 is located within the buckle positioning part 1221 to position the buckle 103.

[0083] In this embodiment, as Figures 12 to 13 As shown, the structure of the buckle limiting member 123 is not strictly limited, as long as the buckle limiting member 123 can limit the buckle pushing member 122 to the third or fourth position; for example, the buckle limiting member 123 is roughly a block structure. The base 121 is provided with a second sliding groove, along which the buckle limiting member 123 can slide to limit its movement path.

[0084] In this embodiment, as Figures 12 to 13 As shown, the buckle limiting member 123, driven by the buckle elastic member 124, abuts against the buckle pushing member 122, thereby limiting the buckle pushing member 122 to the third and fourth positions. This ensures the stability and accuracy of the buckle 103 during the pushing process and prevents assembly errors caused by misoperation or external interference. The elastic force of the buckle elastic member 124 increases the friction between the buckle limiting member 123 and the buckle pushing member 122, thereby increasing the resistance of the buckle pushing member 122 during movement and thus limiting the buckle pushing member 122 to the third and fourth positions.

[0085] In this embodiment, as Figures 12 to 13 As shown, the movement path of the buckle limiting member 123 is approximately perpendicular to the movement path of the buckle pushing member 122. The buckle limiting member 123 is located on one side of the buckle pushing member 122; the end of the buckle limiting member 123 can abut against the side of the buckle pushing member 122. Both the movement paths of the buckle limiting member 123 and the buckle pushing member 122 are perpendicular to the fixed axis of the turntable 11.

[0086] In this embodiment, as Figures 12 to 13As shown, of the buckle limiting member 123 and the buckle pushing member 122, one has a buckle limiting groove 1223, and the other has a buckle limiting protrusion 1231 that mates with the buckle limiting groove 1223. The buckle limiting protrusion 1231 and the buckle limiting groove 1223 ensure that the buckle pushing member 122 is stably limited to the third and fourth positions, thereby improving the positioning accuracy and stability of the buckle pushing member 122, increasing assembly efficiency, and ensuring the accurate assembly position of the buckle 103. The buckle limiting groove 1223 and the buckle limiting protrusion 1231 are located at the point where the buckle limiting member 123 and the buckle pushing member 122 abut.

[0087] In this embodiment, as Figures 12 to 13 As shown, there are two buckle-limiting protrusions 1231 and one buckle-limiting groove 1223. When the buckle-pushing member 122 moves to the third position, the buckle-limiting groove 1223 engages with one of the buckle-limiting protrusions 1231. When the buckle-pushing member 122 moves to the fourth position, the buckle-limiting groove 1223 engages with the other buckle-limiting protrusion 1231. Alternatively, in other embodiments, there are two buckle-limiting grooves 1223 and one buckle-limiting protrusion 1231; when the buckle-pushing member 122 moves to the third position, the buckle-limiting protrusion 1231 engages with one of the buckle-limiting grooves 1223; when the buckle-pushing member 122 moves to the fourth position, the buckle-limiting protrusion 1231 engages with the other buckle-limiting groove 1223.

[0088] Specifically, such as Figures 12 to 13 As shown, there are two buckle-limiting protrusions 1231; along the moving path of the buckle-pushing member 122, the two buckle-limiting protrusions 1231 are spaced apart at the ends of the buckle-limiting member 123. The outer contour of the buckle-limiting protrusion 1231 is approximately arc-shaped, and the outer contour of the buckle-limiting groove 1223 is approximately the same as the outer contour of the buckle-limiting protrusion 1231. This facilitates the separation of the buckle-limiting protrusion 1231 from the buckle-limiting groove 1223.

[0089] In this embodiment, as Figures 12 to 13 As shown, the buckle elastic member 124 is a spring; one end of the spring is connected to the buckle limiting member 123, and the other end is connected to the base 121. Specifically, the spring is connected to the end of the buckle limiting member 123 that pushes the fastener away from the buckle 103.

[0090] The movement of the buckle pusher 122 can be achieved mechanically, pneumatically, or electrically, ensuring the precise positioning and assembly of the buckle 103, further improving assembly efficiency and automation. Referring to one embodiment, such as... Figures 12 to 16As shown, the automatic keychain assembly equipment 100 also includes a buckle drive device 34, which drives the buckle pusher 122 to move to a third position or a fourth position. When the buckle pusher 122 is in the third position, the buckle acquisition mechanism 30 transfers the buckle 103 to the base 121 or the buckle pusher 122. Then, the buckle drive device 34 pushes the buckle 103 until the buckle pusher 122 moves to the fourth position, so that the buckle 103 is assembled onto the buckle body 102 located on the base 121.

[0091] In this embodiment, as Figures 10 to 14 As shown, the buckle driving device 34 includes a buckle driving member 341 and a buckle output member 342. The buckle driving member 341 is configured to drive the buckle pushing member 122 to move to a third position or a fourth position; the buckle output member 342 is configured to drive the buckle driving member 341 to move.

[0092] In this embodiment, as Figures 10 to 14 As shown, in order for the buckle drive device 34 to drive the buckle push member 122 to switch between the third position and the fourth position, there are two buckle drive members 341 and two buckle output members 342. The two buckle output members 342 drive the corresponding buckle drive members 341 respectively.

[0093] Specifically, the buckle driving device 34 includes a first buckle driving component 3411, a first buckle output component 3421, a second buckle driving component 3412, and a second buckle output component 3422. The first buckle driving component 3411 is configured to drive the buckle pushing component 122 from a third position to a fourth position. The first buckle output component 3421 is used to drive the first buckle driving component 3411 to move. The second buckle driving component 3412 is configured to drive the buckle pushing component 122 from a fourth position to a third position. The second buckle output component 3422 is used to drive the second buckle driving component 3412 to move. This achieves precise control and efficient movement of the buckle pushing component 122, further improving assembly efficiency and accuracy.

[0094] In this embodiment, as Figures 10 to 14 As shown, the buckle pushing member 122 has a buckle linkage portion 1222 that cooperates with the first buckle driving member 3411 and the second buckle driving member 3412. The buckle linkage portion 1222 can extend out of the base 121 to the bottom of the turntable 11, so that the first buckle driving member 3411 and the second buckle driving member 3412 can abut against the buckle linkage portion 1222 and push the buckle linkage portion 1222.

[0095] In this embodiment, as Figures 10 to 14As shown, the structures of the first buckle driving member 3411 and the second buckle driving member 3412 are not strictly limited, as long as they can drive the buckle pushing member 122; this will not be elaborated here. For example, both the first buckle driving member 3411 and the second buckle driving member 3412 have a block structure. The first buckle output member 3421 and the second output member can be driven by a cylinder.

[0096] In this embodiment, as Figures 10 to 13 As shown, the first buckle driving member 3411 includes a seat 3413, a pushing part 3414, and an elastic member 3415. The seat 3413 is attached to the first buckle output member 3421. The pushing part 3414 is rotatably attached to the seat 3413 about a fixed axis and has a driving position and a clearance position. The elastic member 3415 is configured to drive the pushing part 3414 to remain in the driving position. When the pushing part 3414 is in the driving position, it can abut against the first buckle driving member 3411 to push the first buckle driving member 3411. When the pushing part 3414 is in the clearance position, it can allow the first buckle driving member 3411 to pass.

[0097] During the process of the turntable 11 moving the clamping fixture 12 to the position corresponding to the buckle acquisition mechanism 30, the buckle linkage part 1222 will press against the pushing part 3414. The pushing part 3414 will swing in a way that compresses the elastic member 3415 so that the pushing part 3414 is in the avoidance position until the clamping fixture 12 moves to the position corresponding to the buckle acquisition mechanism 30. The pushing part 3414 is in the driving position under the reset drive of the elastic member 3415. After the buckle 103 is placed on the buckle pushing member 122, the pushing part 3414 pushes the buckle linkage part 1222 so that the buckle pushing member 122 can be driven to move from the third position to the fourth position.

[0098] In this embodiment, as Figures 10 to 13 As shown, the seat 3413 is fixed to the piston rod of the first buckle output member 3421 by welding or bolts. The seat 3413 has a mounting groove 34131; part of the structure of the pusher 3414 is located in the mounting groove 34131 and is pivotally mounted on the seat 3413.

[0099] In this embodiment, as Figures 10 to 13 As shown, along the rotation direction of the turntable 11, the elastic element 3415 and the rotating axis of the pushing part 3414 are spaced apart. The elastic element 3415 is a spring, and the elastic element 3415 is located in the mounting groove 34131; one end of the elastic element 3415 is connected to the pushing part 3414, and the other end is connected to the seat part 3413.

[0100] In this embodiment, as Figures 10 to 13As shown, when the pushing part 3414 is in the driving position, it is driven by the elastic member 3415 and fits against the groove wall of the mounting groove 34131, so that the movement of the pushing part 3414 can be restricted when pushing the buckle push member 122. The pushing part 3414 has an inclined guide surface 34141 to guide the buckle linkage part 1222 past the pushing part 3414.

[0101] In this embodiment, as Figures 4 to 6 As shown, the buckle acquisition mechanism 30 is used to accurately grasp, position, and release the buckle 103 during the automatic assembly of the keychain 101. The buckle acquisition mechanism 30 includes a buckle gripping device 31 and a buckle separation component 32. The buckle gripping device 31 includes a buckle clamping claw 311 and a buckle positioning component 312. The buckle clamping claw 311 is used to clamp the buckle 103, and the buckle positioning component 312 can extend into the buckle pin hole 1031 of the buckle 103. The buckle separation component 32 is configured to separate the buckle 103 from the buckle gripping device 31. When the buckle clamping claw 311 clamps the buckle 103, the buckle positioning component 312 extends into the buckle pin hole 1031 of the buckle 103 to position the buckle 103, ensuring that the position of the buckle 103 is accurately grasped, providing an accurate reference for subsequent assembly operations. After the buckle 103 is grasped and positioned, it needs to be accurately placed onto the buckle body 102 for assembly. The buckle separation component 32 is used to realize the reliable separation of the buckle 103 from the grasping device, ensuring that the buckle 103 can be smoothly placed in the designated position and complete the assembly with the buckle body 102.

[0102] In this embodiment, as Figures 4 to 6 As shown, the structure of the buckle gripper 311 is not strictly limited, as long as the buckle gripper 311 can grasp the buckle 103; for example, the buckle gripper 311 can be a pneumatic gripper. The buckle gripper 311 includes two arms 3111, which cooperate to grip the buckle 103. The two arms 3111 are pneumatically or electrically driven to open and close, and are used to grip the side wall of the buckle 103.

[0103] In this embodiment, as Figures 4 to 6 As shown, the buckle 103 also includes a buckle pin hole portion 1032 that is convexly arranged; the buckle pin hole portion 1032 is generally cylindrical, and the buckle pin hole 1031 is located at the buckle pin hole portion 1032 and is coaxially arranged with the buckle pin hole portion 1032. The buckle 103 gripper is used to grip the outer side of the buckle pin hole portion 1032; the inner sidewall of the arm portion 3111 is an arc-shaped surface to increase the contact area with the buckle pin hole portion 1032, ensuring a secure grip on the buckle 103.

[0104] In this embodiment, as Figures 4 to 6As shown, the structure of the buckle positioning member 312 is not strictly limited, as long as the buckle positioning member 312 can be inserted into the buckle pin hole 1031 to position the buckle 103; for example, the buckle positioning member 312 is generally rod-shaped.

[0105] In this embodiment, as Figures 4 to 6 As shown, the buckle positioning component 312 is located between the two arm portions 3111, ensuring that the buckle 103 can be stably and accurately positioned during clamping. The buckle positioning component 312 has a transition fit with the buckle pin hole 1031, ensuring that the buckle positioning component 312 can smoothly extend into the buckle 103 hole, while ensuring sufficient stability and accuracy.

[0106] In this embodiment, as Figures 4 to 6 As shown, the end of the buckle positioning member 312 has a buckle guide portion 313 for guiding the buckle positioning member 312 into the buckle pin hole 1031, further improving the accuracy and efficiency of the buckle positioning member 312 entering the buckle pin hole 1031. The buckle guide portion 313 acts as a guide, allowing the buckle positioning member 312 to enter the buckle pin hole 1031 more easily and accurately. The buckle guide portion 313 is tapered or beveled, facilitating the smooth insertion of the buckle positioning member 312 into the buckle pin hole 1031.

[0107] In this embodiment, as Figures 4 to 6 As shown, the buckle separation component 32 allows the buckle 103 to be smoothly released from the gripping device after being precisely positioned and moved to the designated location, facilitating subsequent assembly operations. The buckle separation component 32 also enables rapid release of the buckle 103 from the buckle gripping device 31, preventing jamming. The structure of the buckle separation component 32 is not strictly limited, as long as it can separate the buckle 103 from the buckle gripping device 31; for example, the buckle separation component 32 can be roughly block-shaped.

[0108] In this embodiment, as Figures 4 to 6 As shown, the buckle separation member 32 can abut against the buckle 103, and by applying a certain force or displacement, the buckle 103 can be separated from the buckle positioning member 312, so as to facilitate the separation of the buckle 103 by the buckle separation member 32. The buckle separation member 32 partially surrounds the outer side of the buckle clamping claw 311, so that the force applied by the buckle separation member 32 to the buckle body 102 is more balanced. The bottom of the buckle separation member 32 is provided with an abutment surface.

[0109] In this embodiment, as Figures 4 to 6As shown, the buckle positioning member 312 can move relative to the buckle separating member 32 along a third direction, allowing the buckle positioning member 312 to extend into or disengage from the buckle pin hole 1031. When the buckle positioning member 312 moves along the third direction, the buckle separating member 32 can restrict the buckle 103 from moving with the buckle positioning member 312, ensuring stable separation of the buckle positioning member 312 from the buckle pin hole 1031. The third direction is parallel to the fixed axis of the turntable 11. The buckle acquiring mechanism 30 may be equipped with a drive cylinder, which can drive the buckle positioning member 312 to move along the third direction.

[0110] Of course, in other embodiments, such as Figures 4 to 6 As shown, the buckle separating member 32 can move relative to the buckle positioning member 312 in a third direction, so that the buckle separating member 32 can abut against the buckle 103 to separate the buckle 103 from the buckle 103 positioning member. When the buckle separating member 32 moves in the third direction, it can push the buckle 103 to move in the third direction until the buckle 103 separates from the buckle positioning member 312, thus ensuring the stable separation of the buckle positioning member 312 from the buckle pin hole 1031. The buckle acquiring mechanism 30 may be equipped with a driving cylinder, which can drive the buckle separating member 32 to move in the third direction.

[0111] In this embodiment, as Figures 4 to 6 As shown, the buckle acquisition mechanism 30 also includes a buckle placement device 33, which includes a buckle vibratory feeder 331 and a buckle conveyor line 332. The buckle vibratory feeder 331 conveys the buckle 103 to the buckle conveyor line 332. The turntable 11 drives the clamping fixture 12 to rotate to the buckle acquisition mechanism 30; the buckle gripping device 31 is used to place the buckle 103 conveyed by the buckle conveyor line 332 onto the buckle pushing member 122 of the clamping fixture 12, so as to achieve the effect of automatically transferring the buckle 103 to the clamping fixture 12. The buckle vibratory feeder 331 and the buckle conveyor line 332 can both adopt existing technologies, which will not be further described here.

[0112] In this embodiment, as Figures 4 to 6As shown, in the initial state, the buckle gripping claw 311 is open, and the buckle positioning member 312 is located at the expected position of the buckle pin hole 1031. When the buckle 103 transfer device moves the buckle 103 to the vicinity of the buckle gripping claw 311, the buckle gripping claw 311 closes, and at the same time, the buckle positioning member 312 extends into the buckle pin hole 1031, achieving precise gripping and positioning of the buckle 103. Subsequently, the entire buckle gripping device 31 carries the buckle 103 to the target position of the gripping fixture 12. When it is necessary to release the buckle 103, the buckle separation member 32 moves along a third direction, abuts against and pushes the buckle 103, causing it to separate from the buckle positioning member 312, and the buckle gripping claw 311 opens, completing the release of the buckle 103.

[0113] In this embodiment, as Figures 7 to 9 As shown, the torsion spring acquisition mechanism 40 includes a torsion spring placement device 41, a torsion spring position limiting device 42, a torsion spring pushing device 43, and a torsion spring transfer device 44. The torsion spring placement device 41 is configured to place the torsion springs 104 into an ordered state; the torsion spring position limiting device 42 is configured to limit the ordered torsion springs 104 to an initial position; the torsion spring pushing device 43 is configured to push the torsion springs 104 located at the initial position to a position to be moved; and the torsion spring transfer device 44 is configured to transfer the torsion springs 104 located at the position to be moved to a buckle 103 located on the clamping fixture 12. The distance between the initial position and the position to be moved allows the torsion spring transfer device 44 to avoid the torsion springs 104 located at the initial position when it grabs the torsion springs 104 at the position to be moved.

[0114] The disordered torsion springs 104 are neatly arranged by the torsion spring arranging device 41; then the torsion spring position limiting device 42 precisely fixes these orderly arranged torsion springs 104 in their initial positions to prevent them from moving before being pushed; then the torsion spring pushing device 43 smoothly pushes the torsion springs 104 in their initial positions to the position to be moved; finally, the torsion spring transferring device 44 transfers the torsion springs 104 in the position to be moved to the buckle 103 on the clamping fixture 12, completing the entire process of acquiring and installing the torsion springs 104, so as to achieve the effect of automatically transferring the torsion springs 104 to the clamping fixture 12. The distance between the initial position and the position to be moved not only ensures the smoothness of operation, but also allows the torsion spring transferring device 44 to easily avoid the torsion springs 104 still in their initial positions when grabbing the torsion springs 104 in the position to be moved, avoiding possible interference and conflict, thereby greatly improving the overall work efficiency and safety.

[0115] In this embodiment, as Figures 7 to 9As shown, due to the relatively complex shape and structure of the torsion springs 104, they are prone to becoming disordered during the production process. Therefore, the function of the torsion spring sorting device 41 is to organize these disordered torsion springs 104 into an orderly state, facilitating subsequent operations. The torsion spring sorting device 41 includes a torsion spring vibratory feeder 411 and a torsion spring conveyor line 412. The torsion spring vibratory feeder 411 conveys the torsion springs 104 to the torsion spring conveyor line 412, so that the torsion springs 104 are arranged neatly in a certain direction and posture. Both the torsion spring vibratory feeder 411 and the torsion spring conveyor line 412 can adopt existing technologies, which will not be further described here.

[0116] In this embodiment, as Figures 7 to 9 As shown, after the torsion spring 104 is arranged in an ordered state, it needs to be temporarily restricted to its initial position so that subsequent pushing operations can be performed accurately. The torsion spring position limiting device 42 includes a torsion spring position limiting member 421 and a first driving member 422; the torsion spring position limiting member 421 has a limiting position and a releasing position; the first driving member 422 is used to drive the torsion spring position limiting member 421 to switch between the limiting position and the releasing position; wherein, when the torsion spring position limiting member 421 is in the limiting position, the torsion spring position limiting member 421 can restrict the torsion spring 104 to the initial position; when the torsion spring position limiting member 421 is in the releasing position, the torsion spring pushing device 43 can push the torsion spring 104 located at the initial position to the position to be moved.

[0117] In this embodiment, as Figures 7 to 9 As shown, the torsion spring 104 limiting member includes a first torsion spring position limiting part 4211 and a second torsion spring position limiting part 4212. The first torsion spring position limiting part 4211 has a first limiting position that restricts the movement of the first torsion spring 1041 located in the initial position and a first release position that allows the first torsion spring 1041 to move. The second torsion spring position limiting part 4212 has a second limiting position that restricts the movement of the second torsion spring 1042, which is different from the first torsion spring 1041, and a second release position that allows the second torsion spring 1042 to move. When the first torsion spring position limiting part 4211 is in the first limiting position, the second torsion spring position limiting part 4212 is in the second release position; when the second torsion spring position limiting part 4212 is in the first limiting position, the first torsion spring position limiting part 4211 is in the second release position. The first torsion spring position limiting part 4211 and the second torsion spring position limiting part 4212 can respectively limit the movement of two adjacent torsion springs 104, and when one limiting part is in the limiting position, the other limiting part is in the release position. In this way, the torsion springs 104 can be pushed and moved sequentially without interfering with the adjacent torsion springs 104.

[0118] In this embodiment, as Figures 7 to 9As shown, along the torsion spring 104's movement path in the torsion spring 104 positioning device 41, the first torsion spring position limiting part 4211 in the first release position and the second torsion spring position limiting part 4212 in the second release position are located on opposite sides of the torsion spring 104's movement path. The first driving member 422 can simultaneously drive the first torsion spring position limiting part 4211 and the second torsion spring position limiting part 4212, thereby reducing the transmission structure between the first driving member 422 and the first and second torsion spring position limiting parts 4211 and 4212. The opposite sides of the torsion spring 104's movement path can be understood as the area above and below the torsion spring 104's movement path. The torsion spring conveying line 412 has clearance holes for the first and second torsion spring position limiting parts 4211 and 4212 to pass through.

[0119] In this embodiment, as Figures 7 to 9 As shown, both the first torsion spring position limiting part 4211 and the second torsion spring position limiting part 4212 are rod-shaped structures. The axis of the first torsion spring position limiting part 4211 and the axis of the second torsion spring position limiting part 4212 are arranged approximately parallel to each other. When the first torsion spring position limiting part 4211 is in the first limiting position, it can abut against the side of the first torsion spring 1041 to limit its movement. The side of the first torsion spring position limiting part 4211 facing the first torsion spring 1041 has an arc-shaped surface to ensure stable abutment against the first torsion spring 1041. When the second torsion spring position limiting part 4212 is in the second limiting position, it extends into the torsion spring 104 to limit its movement. The second torsion spring position limiting part 4212 is cylindrical to stably limit its movement. The first driving component 422 can be a driving cylinder.

[0120] In this embodiment, as Figures 7 to 9 As shown, the first torsion spring 1041 and the second torsion spring 1042 are two adjacent torsion springs 104, so that the structure of the torsion spring position limiting device 42 can be more compact; in addition, when the torsion spring transfer device 44 operates the first torsion spring 1041 at the position to be moved, it avoids interfering with the torsion spring 104 between the first torsion spring 1041 and the second torsion spring 1042.

[0121] In this embodiment, as Figures 7 to 9 As shown, the torsion spring pushing device 43 includes a torsion spring pushing member 431 and a second driving member 432; the torsion spring pushing member 431 is configured to push the torsion spring 104, which is located in the initial position, to the position to be moved; the second driving member 432 is used to drive the torsion spring pushing member 431. The torsion spring pushing member 431 acts directly on the torsion spring 104, while the second driving member 432 provides the power required for pushing.

[0122] In this embodiment, as Figures 7 to 9 As shown, the torsion spring pushing member 431 includes a first torsion spring pushing part 4311 and a second torsion spring pushing part 4312. The first torsion spring pushing part 4311 is configured to push the torsion spring 104 located at the initial position to the first position to be moved 45. The second torsion spring pushing part 4312 is configured to push the torsion spring 104 located at the first position to be moved 45 to the second position to be moved 46. In order to more precisely control the movement of the torsion spring 104, the first torsion spring pushing part 4311 pushes the torsion spring 104 from the initial position to the first position to be moved 45, while the second torsion spring pushing part 4312 pushes it from the first position to be moved 45 to the second position to be moved 46.

[0123] In this embodiment, as Figures 7 to 9 As shown, both the first torsion spring pusher 4311 and the second torsion spring pusher 4312 are located below the torsion spring conveyor line 412. The second drive member 432 can drive both the first torsion spring pusher 4311 and the second torsion spring pusher 4312 simultaneously, thereby reducing the transmission structure between the second drive member 432 and the first and second torsion spring pushers 4311 and 4312. The torsion spring conveyor line 412 has a clearance hole for the first torsion spring pusher 4311 and the second torsion spring pusher 4312 to pass through. The first torsion spring pusher 4311, the second torsion spring pusher 4312, and the first torsion spring position limiting member 4211 can share the same clearance hole.

[0124] In this embodiment, as Figures 7 to 9 As shown, both the first torsion spring pushing part 4311 and the second torsion spring pushing part 4312 are rod-shaped structures. The axis of the first torsion spring pushing part 4311 and the axis of the second torsion spring pushing part 4312 are approximately parallel. The first torsion spring pushing part 4311 has a cylindrical structure; it can extend into the torsion spring 104 to stably push the movement of the second torsion spring 1042. The second torsion spring pushing part 4312 has an arc-shaped surface that mates with the torsion spring 104 to stably push the torsion spring 104. The second driving member 432 can be a cylinder.

[0125] In this embodiment, as Figures 7 to 9 As shown, the distance between the initial position and the position to be moved is greater than 10 mm to ensure that the torsion spring transfer device 44 does not interfere with the torsion spring 104 located at the initial position when it grasps the torsion spring 104 at the position to be moved. Preferably, the distance between the initial position and the position to be moved is greater than 15 mm or 20 mm.

[0126] In this embodiment, as Figures 7 to 9As shown, the distance between the first position to be moved 45 and the second position to be moved 46 is greater than 10 mm to ensure that the torsion spring transfer device 44 does not interfere with the torsion spring 104 located at the first position to be moved 45 when it grasps the torsion spring 104 at the second position to be moved 46. Preferably, the distance between the first position to be moved 45 and the second position to be moved 46 is greater than 15 mm or 20 mm.

[0127] In this embodiment, as Figures 7 to 9 As shown, the structure of the torsion spring transfer device 44 is not strictly limited, as long as the torsion spring transfer device 44 can grasp the torsion spring 104. For example, the torsion spring transfer device 44 can be a pneumatic gripper.

[0128] In this embodiment, as Figures 6 to 21 As shown, the torsion spring acquiring mechanism 40 places the torsion spring 104 on the buckle head 103 before assembling the buckle head 103 and the torsion spring 104 together onto the buckle body 102. When the buckle head 103 is assembled onto the buckle body 102, the buckle body pin hole on the buckle body 102 corresponds to the buckle head pin hole 1031; the pin acquiring mechanism 50 can pass the pin through the buckle body pin hole and the buckle head pin hole 1031, and rivet it through the pin riveting mechanism 60.

[0129] In this embodiment, as Figures 15 to 17 As shown, the pin acquisition mechanism 50 can employ existing technology, which will not be further elaborated here. For example, the pin acquisition mechanism 50 includes a pin conveying device 51 and a pin feeding device 52; the pin conveying device 51 is used to convey pins; the pin feeding device 52 is used to place the pins conveyed by the pin conveying device 51 into the buckle body pin hole and the buckle head pin hole 1031.

[0130] In this embodiment, as Figures 15 to 17 As shown, the pin conveying device 51 includes a pin vibrating plate 511 and a pin conveying component 512. The pin vibrating plate 511 conveys pins to the pin conveying component 512, and then the pin feeding device 52 assembles the pins on the pin conveying component 512 into the buckle body pin hole and the buckle head pin hole 1031. A pin release component 513 is provided below the pin conveying component 512 to release the pins located in the pin conveying component 512. When the pins are assembled into the buckle body pin hole and the buckle head pin hole 1031, the pin release component 513 releases the pins in the pin conveying component 512, and the pins enter the buckle body pin hole and the buckle head pin hole 1031 under the guidance of the pin feeding device 52. The pin vibrating plate 511, the pin conveying component 512, and the pin release component 513 can all adopt existing technologies, and their specific structures will not be further described here.

[0131] In this embodiment, as Figures 15 to 17As shown, the pin feeding device 52 includes a pin guide 521 and a first pin drive 522; the first pin drive 522 is fixed to the frame 10 and can drive the pin guide 521 through the buckle body pin hole and the buckle head pin hole 1031, and then guide the pin in the pin conveyor 512 into the buckle body pin hole and the buckle head pin hole 1031.

[0132] In this embodiment, as Figures 15 to 17 As shown, the pin guide 521 is rod-shaped. After passing through the buckle body pin hole and the buckle head pin hole 1031, the pin guide 521 engages with the pin. Then, the pin guide 521, together with the pin, moves away from the pin release member 513, and drives the pin into the buckle body pin hole and the buckle head pin hole 1031. The first pin drive member 522 can be a drive cylinder.

[0133] In this embodiment, as Figures 18 to 19 As shown, the pin riveting mechanism 60 can employ existing technology, which will not be further elaborated here. For example, the pin riveting mechanism 60 includes a pin punch 61 and a second pin drive member 62. The second pin drive member 62 drives the pin punch 61 to punch the pin, thereby riveting the pin into the buckle body pin hole and the buckle head pin hole 1031. The pin riveting mechanism 60 also includes a pin pressing rod 65 and a third pin drive member 66. The third pin drive member 66 is mounted on the frame and is used to drive the pin pressing rod 65 to press against the pin, so that the pin punch 61 can stably punch the pin. The pin pressing rod 65 and the pin punch 61 act on both ends of the pin, respectively.

[0134] In this embodiment, as Figures 18 to 19 As shown, the pin punch 61 has a rod-shaped structure; the second pin drive 62 can be a cylinder. The pin riveting mechanism 60 also includes a pin swing arm 63 and a pin base 64, with the pin punch 61 fixedly connected to the pin base 64; the pin swing arm 63 is rotatably mounted on the frame 10 about a set axis. The second pin drive 62 drives the punching swing arm 831 to swing to drive the pin base 64, and the pin base 64 drives the pin punch 61 to punch the pin.

[0135] In this embodiment, as Figures 20 to 24As shown, the clamping fixture 12 also includes a buckle pushing member 125, which is movably connected to the base 121 via a buckle elastic member 126, and has a first position and a second position. The buckle elastic member 126 provides elastic support and reset for the buckle pushing member 125. When the buckle pushing member 125 is in the second position, it compresses the buckle elastic member 126; the buckle elastic member 126 drives the buckle pushing member 125 to remain in the first position. When the buckle pushing member 125 is in the second position, the buckle acquiring mechanism 70 moves the buckle 106 to the base 121 or the buckle pushing member 125, and then the buckle pushing member 125 pushes the buckle 106 under the reset drive of the buckle elastic member 126 until it moves to the first position, so that the buckle 106 is assembled on the outside of the buckle body 102 located on the base 121, thereby achieving the effect of automatic assembly of the buckle 106.

[0136] In this embodiment, as Figures 20 to 24 As shown, the structure of the buckle pushing member 125 is not strictly limited, as long as the buckle pushing member 125 can push the buckle 106 to move; for example, the buckle pushing member 125 has a block structure. When the buckle 106 is placed on the clamping fixture 12: the buckle 106 can be placed on the base 121 or on the buckle pushing member 125. The base 121 has a buckle limiting groove, and the buckle pushing member 125 can slide along the buckle limiting groove to move the buckle pushing member 125 in a first direction. The first direction is perpendicular to the fixed axis of the turntable 11; the first direction is perpendicular to the movement path of the buckle pushing member 122; and the first direction is parallel to the buckle limiting member 123.

[0137] In this embodiment, as Figures 20 to 24 As shown, the buckle pushing member 125 has a buckle positioning unit 1251. The buckle 106 cooperates with the buckle positioning unit 1251 so that the buckle connecting hole 1061 on the buckle 106 is aligned with the buckle pivot portion 1022 of the buckle body 102. When the buckle pushing member 125 pushes the buckle 106 to move, it can move the buckle connecting hole 1061 on the buckle 106 to the buckle pivot portion 1022 of the buckle body 102, so that the buckle connecting hole 1061 on the buckle 106 is sleeved on the buckle pivot portion 1022 of the buckle body 102, thereby further improving the assembly quality and efficiency of the buckle 106.

[0138] In this embodiment, as Figures 20 to 24As shown, the buckle positioning unit 1251 includes a buckle positioning groove. A portion of the buckle 106 can be positioned within the buckle positioning groove to achieve precise positioning and prevent the buckle 106 from shifting during the pushing process. The buckle positioning unit 1251 also includes a first buckle positioning part 1252 and a second buckle positioning part 1253. The first buckle positioning part 1252 is located on the outer side of the buckle 106; the second buckle positioning part 1253 is located on the inner side of the buckle 106. The first buckle positioning part 1252 and the second buckle positioning part 1253 cooperate with each other to form the buckle positioning groove.

[0139] In this embodiment, as Figures 20 to 24 As shown, there are two first buckle positioning parts 1252, located on the outer side of the buckle 106 and on both sides of the buckle connecting hole 1061. There are also two second buckle positioning parts 1253, located on the inner side of the buckle 106 and on both sides of the buckle connecting hole 1061, so as to correspond to two opposite sides inside the buckle 106. Both the first buckle positioning parts 1252 and the second buckle positioning parts 1253 have a columnar structure.

[0140] In this embodiment, as Figures 20 to 24 As shown, the retaining ring elastic member 126 not only provides the necessary elastic support for the retaining ring pushing member 125, but also ensures its automatic reset function after operation. When the retaining ring pushing member 125 is in the second position, it compresses the retaining ring elastic member 126, accumulating reset energy; while the retaining ring elastic member 126 always maintains the tendency to push the retaining ring pushing member 125 to the first position. The retaining ring elastic member 126 is a spring.

[0141] In this embodiment, as Figures 20 to 24 As shown, the buckle acquisition mechanism 70 includes a buckle placement device 71, a buckle transfer device 72, and a buckle drive device 73; the buckle placement device 71 is used to place the buckles 106 into an ordered state; the buckle transfer device 72 is used to transfer the ordered buckles 106 to the clamping fixture 12; the buckle drive device 73 can drive the buckle pushing member 125 to move from a first position to a second position in a first direction in a manner that compresses the buckle elastic member 126; wherein, the buckle drive device When the buckle pusher 125 is driven to the second position, the buckle transfer device 72 transfers the buckle 106 to the base 121 or the buckle pusher 125. Then, the buckle pusher 125 pushes the buckle 106 under the reset drive of the buckle elastic member 126 until the buckle pusher 125 moves to the first position so that the buckle 106 is assembled on the buckle body 102 located on the base 121, so as to realize the automatic assembly of the buckle body 102 and improve the assembly efficiency of the buckle body 102.

[0142] In this embodiment, as Figures 20 to 24 As shown, due to the relatively complex shape and structure of the buckle 106, it is prone to becoming disordered during the production process. Therefore, the buckle sorting device 71 is used to organize these disordered buckles 106 into an orderly state, facilitating subsequent operations. The buckle sorting device 71 includes a buckle vibratory feeder 711 and a buckle conveyor line 712. The buckle vibratory feeder 711 conveys the buckles 106 to the buckle conveyor line 712, so that the buckles 106 are arranged neatly in a certain direction and posture. Both the buckle vibratory feeder 711 and the buckle conveyor line 712 can adopt existing technologies, which will not be further described here.

[0143] In this embodiment, as Figures 20 to 24 As shown, the structure of the buckle transfer device 72 is not strictly limited, as long as the buckle transfer device 72 can grasp the buckle 106. For example, the buckle transfer device 72 can be a pneumatic gripper.

[0144] In this embodiment, as Figures 20 to 24 As shown, the buckle drive device 73 includes a buckle drive unit 731 and a buckle output member 732. The buckle drive unit 731 is configured to drive the buckle push member 125 from a first position to a second position. The buckle output member 732 is configured to drive the buckle drive unit 731 to move. In operation, the buckle drive device 73 first drives the buckle push member 125 to the second position through the buckle drive unit 731, creating space for the transfer of the buckle 106. Then, the buckle transfer device 72 transfers the buckle 106 to the base 121 or the buckle push member 125. Subsequently, the buckle push member 125 pushes the buckle 106 under the reset drive of the buckle elastic member 126 until the buckle push member 125 moves to the first position, completing the assembly action of the buckle 106.

[0145] In this embodiment, as Figures 20 to 24 As shown, the buckle pushing member 125 has a buckle linkage part 1254 that cooperates with the buckle driving part 731. The buckle linkage part 1254 can extend out of the base 121 to the bottom of the turntable 11, so as to facilitate the buckle driving part 731 and the buckle linkage part 1254 to cooperate with each other to push the buckle pushing member 125. When the buckle driving part 731 pushes the buckle pushing member 125, the buckle driving part 731 and the buckle linkage part 1254 abut against each other.

[0146] In this embodiment, as Figures 20 to 24 As shown, the structure of the retaining ring drive unit 731 is not strictly limited, as long as the retaining ring drive unit 731 can drive the retaining ring linkage unit 1254; for example, the retaining ring drive unit 731 has a block structure. The retaining ring drive unit 731 can abut against the retaining ring linkage unit 1254. The retaining ring output member 732 can be a drive cylinder.

[0147] In this embodiment, as Figures 25 to 27 As shown, the buckle fixing mechanism 80 includes a buckle position limiting member 81, a buckle punch 82, and a first buckle drive member 83. The buckle position limiting member 81 is configured to limit the buckle 106 onto the clamping fixture 12. The buckle punch 82 is configured to punch the buckle 106 to assemble the buckle 106 onto the buckle head 103. The first buckle drive member 83 drives the buckle punch 82. After the buckle position limiting member 81 limits the buckle 106 onto the clamping fixture 12, the first buckle drive member 83 drives the buckle punch 82 to punch the buckle 106 to assemble the buckle 106 onto the buckle body 102. When the buckle 106 is assembled onto the buckle body 102, the buckle fixing mechanism 80 cooperates with the clamping fixture 12, and through the synergistic action of the buckle position limiting member 81, the buckle punch 82, and the buckle head 103, the buckle 106 is assembled quickly and stably.

[0148] In this embodiment, as Figures 25 to 27 As shown, the buckle 106 is sleeved on the outside of the buckle body 102. The buckle punch 82 can punch the buckle 106 to deform the buckle 106 and restrict the buckle 106 on the buckle body 102. Specifically, the buckle position limiting member 81 restricts the buckle 106 on the clamping fixture 12, and the buckle punch 82 applies force to the outside of the buckle connecting hole 1061 of the buckle 106 to deform the buckle 106 and prevent it from disengaging from the buckle body pivot portion 1022.

[0149] In this embodiment, as Figures 25 to 27 As shown, the buckle position limiting member 81 is configured to restrict the buckle 106 on the clamping fixture 12 to prevent the buckle 106 from shifting during the fixing process. It can limit the buckle 106 by clamping, blocking, or other means to ensure that the buckle 106 maintains a stable position during the fixing operation.

[0150] In this embodiment, as Figures 25 to 27 As shown, the buckle position limiting member 81 abuts against the buckle 106 above it to limit the buckle 106. The structure of the buckle position limiting member 81 is not strictly limited, as long as the position limiting member can abut against the buckle 106; for example, the buckle position limiting member 81 is a rod-shaped structure.

[0151] In this embodiment, as Figures 25 to 27 As shown, the frame 10 has a sliding hole, and the buckle position limiting member 81 can slide along the sliding hole. The sliding hole can limit the movement path of the buckle position limiting member 81. The movement path of the buckle position limiting member 81 is parallel to the fixed axis of the turntable 11.

[0152] In this embodiment, as Figures 25 to 27As shown, the buckle position limiting member 81 is movably attached to the frame 10 by means of an elastic member 84; wherein, the buckle position limiting member 81 has a limiting position and a releasing position, the elastic member 84 drives the buckle 106 limiting member to remain in the releasing position, and the buckle 106 position limiting member is in the limiting position by compressing the elastic member 84.

[0153] In this embodiment, as Figures 25 to 27 As shown, the elastic member 84 is a spring. The elastic member 84 presses against the buckle position limiting member 81 and the frame 10. Specifically, the buckle position limiting member 81 has a pressing end 811 and a fixing end 812 arranged opposite to each other. The pressing end 811 of the buckle position limiting member 81 can press against the buckle 106, and the fixing end 812 extends to the outside of the frame 10 through a sliding hole. The elastic member 84 is sleeved on the outside of the buckle position limiting member 81 and presses against the frame 10 and the fixing end 812.

[0154] In an embodiment, such as Figures 25 to 27 As shown, the buckle fixing mechanism 80 also includes a buckle wedge block 85 and a buckle driving assembly 86. The buckle wedge block 85 is fixed to the buckle position limiting member 81. The buckle driving assembly 86 includes a buckle driving block 861 and a second buckle driving member 862. The buckle driving block 861 is configured to be driven by the second buckle driving member 862 to move and press against the buckle wedge block 85, so as to drive the buckle position limiting member 81 from the release position to the limiting position, thereby improving the stability and accuracy of the buckle position limiting member 81 and ensuring the stability and accuracy of the buckle 106 during the assembly process.

[0155] In an embodiment, such as Figures 25 to 27 As shown, the retaining ring wedge 85 is fixed to the retaining ring position limiting member 81 by welding, bonding, or bolting. The retaining ring wedge 85 has a driving surface 851, which is inclined to the moving path of the retaining ring driving block 861. When the retaining ring driving block 861 abuts against the driving surface 851, it can push the retaining ring wedge 85 to move along the fixed axis of the turntable 11, thereby driving the retaining ring position limiting member 81 to move towards the retaining ring 106 until the retaining ring position limiting member 81 abuts against the retaining ring 106.

[0156] In an embodiment, such as Figures 25 to 27 As shown, the structure of the retaining ring drive block 861 is not strictly limited, as long as the retaining ring drive block 861 can drive the retaining ring wedge block 85. The second retaining ring drive component 862 can be a cylinder.

[0157] In an embodiment, such as Figures 25 to 27As shown, the retaining ring fixing mechanism 80 also includes a guide rail 835, which is configured to guide the movement of the retaining ring drive block 861. The guide rail 835 ensures the stability and accuracy of the retaining ring drive block 861 during movement, avoiding assembly errors caused by path deviation. The guide rail 835 is a groove formed on the frame 10.

[0158] In an embodiment, such as Figures 25 to 27 As shown, the moving path of the buckle drive block 861 is perpendicular to the moving path of the buckle position limiting member 81. This design enables the buckle position limiting member 81 to move quickly and stably to the limiting position when driven.

[0159] In this embodiment, as Figures 25 to 27 As shown, the snap ring punch 82 is a key component used to apply pressure to the snap ring 106, enabling it to be securely attached to the buckle 103. It can be designed with appropriate shape and size according to the structural characteristics of the snap ring 106 and the buckle 103, applying appropriate force to tightly connect the snap ring 106 and the buckle 103, thus completing the fixing operation of the snap ring 106. For example, the snap ring punch 82 has a rod-shaped structure; the bottom of the snap ring punch 82 is adapted to the outer side of the snap ring 106.

[0160] In this embodiment, as Figures 25 to 27 As shown, the first retaining ring drive 83 is used to drive the retaining ring punch 82 to move, thereby realizing the stamping operation on the retaining ring 106.

One end of the stamping swing arm 831 engages with the first buckle drive member 83, and the other end engages with the buckle 106 punch.

[0163] In this embodiment, as Figures 25 to 27As shown, the transmission assembly also includes a movable seat 832 and a guide member 834. The retaining ring punch 82 is fixedly connected to the movable seat 832. The guide member 834 guides the movement path of the movable seat 832. The stamping rocker arm 831 drives the movable seat 832 to move the retaining ring punch 82, ensuring the stability and accuracy of the retaining ring punch 82 during the stamping process. The stamping rocker arm 831 abuts against the movable seat 832. A roller 8311 is provided at the end of the stamping rocker arm 831 that abuts against the movable seat 832 to reduce friction between the stamping rocker arm 831 and the movable seat 832.

[0164] In this embodiment, as Figures 25 to 27 As shown, the guide member 834 can be a guide rail, slide rail, or other structure, used to ensure the stability and accuracy of the moving seat 832 during movement.
