[0019] In this embodiment, if Figure 2 As shown, the buckle body 102 has a buckle opening 1021 and a buckle body pin hole; the buckle head 103 has a buckle head pin hole 1031, and a pin is riveted and fixed in the buckle body pin hole and the buckle head pin hole 1031, so that the buckle head 103 is rotatably attached to the buckle body 102 through the pin, and the buckle head 103 can open or close the buckle opening 1021 during the rotation process; the torsion spring 104 is arranged between the buckle head 103 and the buckle body 102 to be able to drive the buckle head 103 to be in a state of closing the buckle opening 1021; the buckle 106 has a buckle ring connecting hole 1061, and the buckle ring connecting hole 1061 is arranged on the outside of the buckle body pivot portion 1022 of the buckle body 102, so that the buckle 106 can rotate relative to the buckle body 102.

[0020] In this embodiment, if Figure 1As shown, the frame 10 serves as the supporting structure of the equipment. The frame 10 is used to carry and fix other components to ensure the stability and reliability of the entire equipment. There is no strict limitation on the structure of the frame 10. It can support the turntable 11, the buckle body acquisition mechanism 20, the buckle head acquisition mechanism 30, the torsion spring acquisition mechanism 40, the pin acquisition mechanism 50, the buckle acquisition mechanism 70, the pin riveting mechanism 60, the buckle fixing mechanism 80, and the finished product material collection mechanism 90. No further explanation is given here. For example, the frame 10 can be in the shape of a frame structure. Among them, the bottom of the frame 10 is provided with moving wheels to facilitate the movement of the entire hook and buckle automatic assembly equipment 100.

[0021] In this embodiment, if 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-style operations and improves assembly efficiency. When the hook and buckle automated assembly equipment 100 is in operation, the turntable 11 rotates about a vertical axis. The hook and buckle automated assembly equipment 100 also includes a motor for driving the turntable 11. Multiple clamping jigs 12 are spaced apart circumferentially around the turntable 11.

[0022] In this embodiment, if 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 removal mechanism 90 are arranged at intervals around the outer circumference of the turntable 11. The turntable 11 can drive the clamping fixture 12 during rotation, so that the clamping fixture 12 has multiple working stations; each working station corresponds 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 removal mechanism 90.

[0023] In this embodiment, if Figures 1 to 2As shown, the clamping jig 12 is fixed to the turntable 11; the clamping jig 12 is used to carry and position the various components of the hook 101 to ensure stability and accuracy during the assembly process. There is no strict requirement for the number of clamping jigs 12, and it can be adjusted according to actual needs. It will not be further elaborated here. For example, the number of clamping jigs 12 is 8, and the 8 clamping jigs 12 can respectively correspond to the buckle body 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 picking mechanism 90, so that the buckle body 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 picking mechanism 90 can work synchronously, thereby improving the working efficiency of the hook automatic assembly equipment 100. Of course, the number of the clamping fixtures 12 may be greater than 8; for example, 9, 10, 11, 12, 13, 14, 15 or 16.

[0024] In this embodiment, if 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 in the shape of a block structure.

[0025] In this embodiment, if Figure 1 and Figure 3 As shown, the base 121 has a slot for placing the button body 102; the button body acquisition mechanism 20 is capable of placing the button body 102 in the slot. The button body acquisition mechanism 20 includes a button body placement device 21 and a button body transfer device 22. The button body placement device 21 is configured to place the button bodies 102 in an orderly state, and the button body transfer device 22 is configured to transfer the orderly button bodies 102 to the placement slot.

[0026] In this embodiment, if Figure 3As shown, the button body placement device 21 includes a button body vibration disk 211 and a button body conveyor line 212. The button body vibration disk 211 conveys the button body 102 to the button body conveyor line 212 to organize the scattered button bodies 102 into an orderly state for easy subsequent operation. The button body transfer device 22 includes a button body clamp 221. The turntable 11 drives the clamping jig 12 to rotate to the button body acquisition mechanism 20; the button body clamp 221 is used to place the button body 102 conveyed by the button body conveyor line 212 into the placement slot of the clamping jig 12, so as to achieve the effect of automatically transferring the button body 102 to the clamping jig 12. The button body vibration disk 211, the button body conveyor line 212 and the button body clamp 221 can all adopt existing technologies and will not be further elaborated here.

[0027] In this embodiment, if 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 by 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 transfers the buckle 103 to the base 121 or the buckle pushing member 122, and 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 to the buckle body 102 located on the base 121, so as to achieve the effect of automatic assembly of the buckle 103.

[0028] In this embodiment, if 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-shaped 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 slide groove, and the buckle pushing member 122 can slide along the first slide groove to limit the movement path of the buckle pushing member 122.

[0029] In this embodiment, if Figures 12 to 13As shown, the buckle pushing member 122 has a buckle positioning portion 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 portion 1221 can position the buckle 103, ensuring accurate alignment of the buckle 103 with the buckle body 102 during assembly, further improving the assembly quality and efficiency of the buckle 103. The buckle positioning portion 1221 is a slot structure; part of the structure of the buckle 103 is located within the buckle positioning portion 1221 to locate the buckle 103.

[0030] In this embodiment, if Figures 12 to 13 As shown, the structure of the buckle head limiting member 123 is not strictly limited, as long as the buckle head limiting member 123 can limit the buckle head pushing member 122 to the third position or the fourth position; for example, the buckle head limiting member 123 is generally a block-shaped structure. The base 121 is provided with a second sliding groove, and the buckle head limiting member 123 can slide along the second sliding groove to limit the movement path of the buckle head limiting member 123.

[0031] In this embodiment, if Figures 12 to 13 As shown, the buckle limiting member 123 is driven by the buckle elastic member 124 to abut against the buckle pushing member 122, so as to limit the buckle pushing member 122 to the third position and the fourth position, thereby ensuring the stability and accuracy of the buckle 103 during the pushing process and preventing assembly errors caused by misoperation or external interference. The elastic force of the buckle elastic member 124 can increase 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 the movement process, thereby limiting the buckle pushing member 122 to the third position and the fourth position.

[0032] In this embodiment, if Figures 12 to 13 As shown, the movement path of the buckle head limiting member 123 is substantially perpendicular to the movement path of the buckle head pushing member 122. The buckle head limiting member 123 is located on one side of the buckle head pushing member 122; the end of the buckle head limiting member 123 can abut against the side of the buckle head pushing member 122. The movement paths of the buckle head limiting member 123 and the buckle head pushing member 122 are both perpendicular to the fixed axis of the turntable 11.

[0033] In this embodiment, if Figures 12 to 13As shown, one of the buckle limiting member 123 and the buckle pushing member 122 has a buckle limiting groove 1223, and the other is provided with a buckle limiting protrusion 1231 that cooperates with the buckle limiting groove 1223; the arrangement of the buckle limiting protrusion 1231 and the buckle limiting groove 1223 can stably limit the buckle pushing member 122 to the third position and the fourth position, thereby improving the positioning accuracy and stability of the buckle pushing member 122, and also improving the assembly efficiency, ensuring the accurate assembly position of the buckle 103. Among them, the buckle limiting groove 1223 and the buckle limiting protrusion 1231 are located at the abutment between the buckle limiting member 123 and the buckle pushing member 122.

[0034] In this embodiment, if Figures 12 to 13 As shown, there are two buckle head limiting protrusions 1231 and one buckle head limiting groove 1223; when the buckle head pushing member 122 moves to the third position, the buckle head limiting groove 1223 cooperates with one of the buckle head limiting protrusions 1231; when the buckle head pushing member 122 moves to the fourth position, the buckle head limiting groove 1223 cooperates with the other buckle head limiting protrusion 1231. Of course, in other embodiments, there are two buckle head limiting grooves 1223 and one buckle head limiting protrusion 1231; when the buckle head pushing member 122 moves to the third position, the buckle head limiting protrusion 1231 cooperates with one of the buckle head limiting grooves 1223; when the buckle head pushing member 122 moves to the fourth position, the buckle head limiting protrusion 1231 cooperates with the other buckle head limiting groove 1223.

[0035] Specifically, if Figures 12 to 13 As shown, there are two buckle-stopping protrusions 1231; along the movement path of the buckle-stop pushing member 122, the two buckle-stopping protrusions 1231 are spaced apart at the ends of the buckle-stopping member 123. The outer contour of the buckle-stopping protrusions 1231 is generally arc-shaped, and the outer contour of the buckle-stopping groove 1223 is generally the same as the outer contour of the buckle-stopping protrusions 1231. This facilitates the separation of the buckle-stopping protrusions 1231 from the buckle-stopping groove 1223.

[0036] In this embodiment, if 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.

[0037] The movement of the buckle head pushing member 122 can be achieved by mechanical, pneumatic or electric means to ensure the accurate positioning and assembly of the buckle head 103, further improving the assembly efficiency and automation level. Figures 12 to 16As shown, the automatic hook and buckle assembly device 100 further includes a buckle driving device 34, which is used to drive the buckle pushing member 122 to move to the third position or the fourth position. When the buckle pushing member 122 is in the third position, the buckle acquiring mechanism 30 transfers the buckle 103 to the base 121 or the buckle pushing member 122, and then the buckle driving device 34 pushes the buckle 103 until the buckle pushing member 122 moves to the fourth position, so that the buckle 103 is assembled on the buckle body 102 located on the base 121.

[0038] In this embodiment, if 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 the third position or the fourth position; the buckle output member 342 is configured to drive the buckle driving member 341 to move.

[0039] In this embodiment, if Figures 10 to 14 As shown, in order to enable the buckle driving device 34 to drive the buckle pushing component 122 to switch between the third position and the fourth position; the number of buckle driving components 341 is two; the number of buckle output components 342 is two; the two buckle output components 342 respectively drive the corresponding buckle driving components 341.

[0040] 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 to move from the third position to the 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 to move from the fourth position to the third position; the second buckle output component 3422 is used to drive the second buckle driving component 3412 to move; precise control and efficient movement of the buckle pushing component 122 are achieved, further improving assembly efficiency and accuracy.

[0041] In this embodiment, if 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 from 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.

[0042] In this embodiment, if 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 is not elaborated here. For example, the first buckle driving member 3411 and the second buckle driving member 3412 are both block-shaped structures. The first buckle output member 3421 and the second output member can be driven by a cylinder.

[0043] In this embodiment, if Figures 10 to 13 As shown, the first buckle driving member 3411 includes a seat 3413, a pushing portion 3414 and an elastic member 3415; the seat 3413 is attached to the first buckle output member 3421; the pushing portion 3414 is rotatable about a fixed axis and is attached to the seat 3413, and has a driving position and a avoidance position; the elastic member 3415 is configured to drive the pushing portion 3414 to remain in the driving position. When the pushing portion 3414 is in the driving position, the pushing portion 3414 can abut against the first buckle driving member 3411 to push the first buckle driving member 3411; when the pushing portion 3414 is in the avoidance position, the pushing portion 3414 can allow the first buckle driving member 3411 to pass.

[0044] When the turntable 11 drives the clamping fixture 12 to move to the position corresponding to the buckle acquisition mechanism 30, the buckle linkage part 1222 will press the pushing part 3414, and the pushing part 3414 will swing in a manner of compressing the elastic part 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, and the pushing part 3414 is in the driving position under the reset drive of the elastic part 3415; after the buckle 103 is placed on the buckle pushing component 122, the pushing part 3414 pushes the buckle linkage part 122 to drive the buckle pushing component 122 to move from the third position to the fourth position.

[0045] In this embodiment, if 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.

[0046] In this embodiment, if Figures 10 to 13 As shown, along the rotation direction of the turntable 11, the elastic member 3415 is spaced apart from the rotation axis of the push portion 3414. The elastic member 3415 is a spring and is located in the mounting groove 34131. One end of the elastic member 3415 is connected to the push portion 3414, and the other end is connected to the seat 3413.

[0047] In this embodiment, if Figures 10 to 13As shown, when the pushing portion 3414 is in the driving position, the pushing portion 3414 is driven by the elastic member 3415 to fit the groove wall of the installation groove 34131, so that the pushing portion 3414 can limit the movement of the pushing portion 3414 when pushing the buckle pushing member 122. The pushing portion 3414 has an inclined guide surface 34141 to guide the buckle linkage portion 1222 to pass over the pushing portion 3414.

[0048] In this embodiment, if Figures 4 to 6 As shown, the buckle head acquisition mechanism 30 is used to accurately grasp, position and release the buckle head 103 during the automatic assembly process of the hook 101. The buckle head acquisition mechanism 30 includes a buckle head grasping device 31 and a buckle head separation component 32. The buckle head grasping device 31 includes a buckle head clamping claw 311 and a buckle head positioning component 312. The buckle head clamping claw 311 is used to clamp the buckle head 103, and the buckle head positioning component 312 can be inserted into the buckle head pin hole 1031 of the buckle head 103; the buckle head separation component 32 is configured to separate the buckle head 103 from the buckle head grasping device 31; wherein, when the buckle head clamping claw 311 clamps the buckle head 103, the buckle head positioning component 312 is inserted into the buckle head pin hole 1031 of the buckle head 103, so as to be able to position the buckle head 103, ensure that the position of the buckle head 103 is accurate, and provide an accurate reference for subsequent assembly operations. After completing the grasping and positioning of the buckle head 103, the buckle head 103 needs to be accurately placed on the buckle body 102 for assembly. The function of the buckle head separation component 32 is to achieve reliable separation of the buckle head 103 from the grasping device, ensuring that the buckle head 103 can be smoothly placed in the designated position and complete the assembly with the buckle body 102.

[0049] In this embodiment, if Figures 4 to 6 As shown, the structure of the buckle head clamping claw 311 is not strictly limited, as long as the buckle head clamping claw 311 is capable of grasping the buckle head 103; for example, the buckle head clamping claw 311 is a pneumatic clamping claw. The buckle head clamping claw 311 includes two arms 3111, which cooperate with each other to clamp the buckle head 103. The two arms 3111 are opened and closed by pneumatic or electric drive to clamp the side walls of the buckle head 103.

[0050] In this embodiment, if Figures 4 to 6 As shown, the buckle 103 also includes a buckle pin hole portion 1032 that is convex and generally cylindrical, and the buckle pin hole 1031 is located at the buckle pin hole portion 1032 and is coaxial with the buckle pin hole portion 1032. The buckle 103 gripper is used to grasp 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 surface with the buckle pin hole portion 1032, ensuring that the buckle 103 can be firmly grasped.

[0051] In this embodiment, if 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 roughly a rod-shaped structure.

[0052] In this embodiment, if Figures 4 to 6 As shown, the buckle head positioning member 312 is located between the two arms 3111, ensuring that the buckle head 103 can be stably and accurately positioned during the clamping process. The buckle head positioning member 312 and the buckle head pin hole 1031 are in a transitional fit, ensuring that the buckle head positioning member 312 can smoothly extend into the pin buckle head 103 hole while ensuring sufficient stability and accuracy.

[0053] In this embodiment, if Figures 4 to 6 As shown, the end of the buckle head positioning member 312 has a buckle head guide portion 313 for guiding the buckle head positioning member 312 into the buckle head pin hole 1031, further improving the accuracy and efficiency of the buckle head positioning member 312 entering the buckle head pin hole 1031. The buckle head guide portion 313 serves as a guide, allowing the buckle head positioning member 312 to enter the buckle head pin hole 1031 more easily and accurately. The buckle head guide portion 313 is designed with a tapered or inclined surface, which facilitates the buckle head positioning member 312 to smoothly enter the buckle head pin hole 1031.

[0054] In this embodiment, if Figures 4 to 6 As shown, the buckle head separation component 32 allows the buckle head 103 to be smoothly released from the grasping device after being accurately positioned and moved to the designated position, facilitating subsequent assembly operations. The buckle head separation component 32 can also achieve rapid release of the buckle head 103 from the buckle head grasping device 31 to avoid jamming. The structure of the buckle head separation component 32 is not strictly limited, as long as the buckle head separation component 32 can separate the buckle head 103 from the buckle head grasping device 31; for example, the buckle head separation component 32 is roughly a block structure.

[0055] In this embodiment, if Figures 4 to 6 As shown, the buckle head separation member 32 can abut the buckle head 103 and, by applying a certain force or displacement, separate the buckle head 103 from the buckle head positioning member 312, thereby facilitating the buckle head separation member 32 to separate the buckle head 103. The buckle head separation member 32 semi-encloses the outer side of the buckle head clamping claw 311, so that the force applied by the buckle head separation member 32 to the buckle body 102 is more balanced. The bottom of the buckle head separation member 32 is provided with an abutment surface.

[0056] In this embodiment, if Figures 4 to 6As shown, the buckle head positioning member 312 can move relative to the buckle head separation member 32 along the third direction, so that the buckle head positioning member 312 can extend into or out of the buckle head pin hole 1031. When the buckle head positioning member 312 moves along the third direction, the buckle head separation member 32 can limit the buckle head 103 from moving with the buckle head positioning member 312, so as to ensure the stable separation of the buckle head positioning member 312 from the buckle head pin hole 1031. The third direction is arranged parallel to the fixed axis of the turntable 11. Among them, the buckle head acquisition mechanism 30 can be provided with a driving cylinder, which can drive the buckle head positioning member 312 to realize movement along the third direction.

[0057] Of course, in other embodiments, such as Figures 4 to 6 As shown, the buckle head separation member 32 can move relative to the buckle head positioning member 312 along the third direction, so that the buckle head separation member 32 can push the buckle head 103 to separate the buckle head 103 from the buckle head 103 positioning member. When the buckle head separation member 32 moves along the third direction, the buckle head separation member 32 can push the buckle head 103 to move along the third direction until the buckle head 103 is separated from the buckle head positioning member 312, so as to ensure the stable separation of the buckle head positioning member 312 from the buckle head pin hole 1031. The buckle head acquisition mechanism 30 can be provided with a driving cylinder, which can drive the buckle head separation member 32 to achieve movement along the third direction.

[0058] In this embodiment, if Figures 4 to 6 As shown, the buckle head acquisition mechanism 30 also includes a buckle head placement device 33, which includes a buckle head vibration disk 331 and a buckle head conveyor line 332. The buckle head vibration disk 331 conveys the buckle head 103 to the buckle head conveyor line 332. The turntable 11 drives the clamping fixture 12 to rotate to the buckle head acquisition mechanism 30; the buckle head grasping device 31 is used to place the buckle head 103 conveyed by the buckle head conveyor line 332 on the buckle head pushing component 122 of the clamping fixture 12, so as to achieve the effect of automatically transferring the buckle head 103 to the clamping fixture 12. Both the buckle head vibration disk 331 and the buckle head conveyor line 332 can adopt existing technologies and will not be further elaborated here.

[0059] In this embodiment, if Figures 4 to 6As shown, in the initial state, the buckle head clamping claw 311 is in an open state, and the buckle head positioning member 312 is located at the expected position of the buckle head pin hole 1031. When the buckle head 103 transfer device transfers the buckle head 103 to the vicinity of the buckle head clamping claw 311, the buckle head clamping claw 311 is closed, and at the same time, the buckle head positioning member 312 extends into the buckle head pin hole 1031 to achieve accurate grasping and positioning of the buckle head 103. Subsequently, the entire buckle head grasping device 31 carries the buckle head 103 to the target position of the clamping jig 12. When the buckle head 103 needs to be released, the buckle head separation member 32 moves along the third direction, abuts and pushes the buckle head 103, so that it is separated from the buckle head positioning member 312, and the buckle head clamping claw 311 opens, completing the release of the buckle head 103.

[0060] In this embodiment, if Figures 7 to 9 As shown, the torsion spring acquisition mechanism 40 includes a torsion spring placing device 41, a torsion spring position limiting device 42, a torsion spring pushing device 43 and a torsion spring transferring device 44. The torsion spring placing device 41 is configured to place the torsion spring 104 into an ordered state; the torsion spring position limiting device 42 is configured to limit the torsion spring 104 in the ordered state to an initial position; the torsion spring pushing device 43 is configured to push the torsion spring 104 at the initial position to the position to be moved; the torsion spring transferring device 44 is configured to transfer the torsion spring 104 at the position to be moved to the buckle 103 located on the clamping fixture 12; wherein, the distance between the initial position and the position to be moved can allow the torsion spring transferring device 44 to avoid the torsion spring 104 at the initial position when grabbing the torsion spring 104 at the position to be moved.

[0061] The disordered torsion springs 104 are neatly and orderly arranged by the torsion spring placement device 41; then the torsion spring position limiting device 42 accurately fixes these orderly arranged torsion springs 104 in the initial position to prevent them from moving before being pushed; then the torsion spring pushing device 43 smoothly pushes the torsion spring 104 in the initial position to the waiting position; finally, the torsion spring transfer device 44 transfers the torsion spring 104 in the waiting position to the buckle 103 on the clamping fixture 12, completing the entire torsion spring 104 acquisition and installation process, so as to achieve the effect of automatically transferring the torsion spring 104 to the clamping fixture 12. The spacing between the initial position and the waiting position not only ensures smooth operation, but also enables the torsion spring transfer device 44 to easily avoid the torsion spring 104 still in the initial position when grabbing the torsion spring 104 in the waiting position, avoiding possible interference and conflict, thereby greatly improving overall work efficiency and safety.

[0062] In this embodiment, if Figures 7 to 9As shown, due to the relatively complex shape and structure of the torsion spring 104, disorder is likely to occur during the production process. Therefore, the function of the torsion spring placement device 41 is to organize these disordered torsion springs 104 into an orderly state to facilitate subsequent operations. The torsion spring placement device 41 includes a torsion spring vibration disk 411 and a torsion spring conveyor line 412. The torsion spring vibration disk 411 conveys the torsion spring 104 to the torsion spring conveyor line 412 so that the torsion spring 104 is neatly arranged in a certain direction and posture. The torsion spring vibration disk 411 and the torsion spring conveyor line 412 can both adopt existing technologies and will not be further elaborated here.

[0063] In this embodiment, if Figures 7 to 9 As shown, after the torsion spring 104 is placed in an orderly state, it needs to be temporarily restricted to the initial position so that the subsequent pushing operation can be carried out 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 release 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 release position; wherein, when the torsion spring position limiting member 421 is in the limiting position, the torsion spring position limiting member 421 can limit the torsion spring 104 to the initial position, and when the torsion spring position limiting member 421 is in the release position, the torsion spring pushing device 43 can push the torsion spring 104 at the initial position to the waiting position.

[0064] In this embodiment, if Figures 7 to 9 As shown, the torsion spring 104 limiting member includes a first torsion spring position limiting portion 4211 and a second torsion spring position limiting portion 4212. The first torsion spring position limiting portion 4211 has a first limiting position for limiting the movement of the first torsion spring 1041 located in the initial position and a first release position for allowing the first torsion spring 1041 to move. The second torsion spring position limiting portion 4212 has a second limiting position for limiting the movement of a second torsion spring 1042 different from the first torsion spring 1041 and a second release position for allowing the second torsion spring 1042 to move. When the first torsion spring position limiting portion 4211 is in the first limiting position, the second torsion spring position limiting portion 4212 is in the second release position. When the second torsion spring position limiting portion 4212 is in the first limiting position, the first torsion spring position limiting portion 4211 is in the second release position. The first torsion spring position limiting portion 4211 and the second torsion spring position limiting portion 4212 can each limit the movement of two adjacent torsion springs 104. When one limiting portion is in the limiting position, the other limiting portion is in the release position. In this way, the torsion springs 104 can be pushed and transferred sequentially without interfering with adjacent torsion springs 104 .

[0065] In this embodiment, if Figures 7 to 9As shown, along the moving path of the torsion spring 104 in the torsion spring placement device 41, the first torsion spring position limiting portion 4211 located at the first release position and the second torsion spring position limiting portion 4212 located at the second release position are located on both sides of the moving path of the torsion spring 104; the first driving member 422 can drive the first torsion spring position limiting portion 4211 and the second torsion spring position limiting portion 4212 at the same time, so as to reduce the transmission structure between the first driving member 422 and the first torsion spring position limiting portion 4211 and the second torsion spring position limiting portion 4212. The two sides of the moving path of the torsion spring 104 can be understood as: the upper and lower sides of the moving path of the torsion spring 104. Among them, the torsion spring conveying line 412 has an avoidance hole for the first torsion spring position limiting portion 4211 and the second torsion spring position limiting portion 4212 to pass through.

[0066] In this embodiment, if Figures 7 to 9 As shown, both the first torsion spring position limiting portion 4211 and the second torsion spring position limiting portion 4212 have rod-shaped structures. The axis of the first torsion spring position limiting portion 4211 is substantially parallel to the axis of the second torsion spring position limiting portion 4212. When the first torsion spring position limiting portion 4211 is in the first limiting position, it can abut against the side of the first torsion spring 1041 to limit the movement of the first torsion spring 1041. The first torsion spring position limiting portion 4211 has an arcuate surface on the side facing the first torsion spring 1041, so that the first torsion spring position limiting portion 4211 can stably abut against the first torsion spring 1041. When the second torsion spring position limiting portion 4212 is in the second limiting position, it extends into the torsion spring 104 to limit the movement of the second torsion spring 1042. The second torsion spring position limiting portion 4212 has a cylindrical structure, which can stably limit the movement of the second torsion spring 1042. The first driving member 422 may be a driving cylinder.

[0067] In this embodiment, if 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 made 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.

[0068] In this embodiment, if 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 from the initial position to the waiting position. The second driving member 432 is used to drive the torsion spring pushing member 431. The torsion spring pushing member 431 directly acts on the torsion spring 104, while the second driving member 432 provides the driving force required.

[0069] In this embodiment, if Figures 7 to 9 As shown, the torsion spring pushing member 431 includes a first torsion spring pushing portion 4311 and a second torsion spring pushing portion 4312. The first torsion spring pushing portion 4311 is configured to push the torsion spring 104 at the initial position to the first pre-position 45, while the second torsion spring pushing portion 4312 is configured to push the torsion spring 104 at the first pre-position 45 to the second pre-position 46. To more precisely control the movement of the torsion spring 104, the first torsion spring pushing portion 4311 pushes the torsion spring 104 from the initial position to the first pre-position 45, while the second torsion spring pushing portion 4312 pushes the torsion spring 104 from the first pre-position 45 to the second pre-position 46.

[0070] In this embodiment, if Figures 7 to 9 As shown, the first torsion spring pushing portion 4311 and the second torsion spring pushing portion 4312 are both located below the torsion spring conveying line 412. The second driving member 432 can simultaneously drive the first torsion spring pushing portion 4311 and the second torsion spring pushing portion 4312, so as to reduce the transmission structure between the second driving member 432 and the first torsion spring pushing portion 4311 and the second torsion spring pushing portion 4312. The torsion spring conveying line 412 has an avoidance hole for the first torsion spring pushing portion 4311 and the second torsion spring pushing portion 4312 to pass through. Among them, the first torsion spring pushing portion 4311, the second torsion spring pushing portion 4312 and the first torsion spring position limiting portion 4211 can share the same avoidance hole.

[0071] In this embodiment, if Figures 7 to 9 As shown, the first torsion spring pushing portion 4311 and the second torsion spring pushing portion 4312 are both rod-shaped structures. The axis of the first torsion spring pushing portion 4311 is arranged approximately parallel to the axis of the second torsion spring pushing portion 4312. The first torsion spring pushing portion 4311 is a cylindrical structure; the first torsion spring pushing portion 4311 can extend into the torsion spring 104 to stably push the movement of the second torsion spring 1042. The second torsion spring pushing portion 4312 has an arcuate surface that cooperates with the torsion spring 104 to stably push the torsion spring 104. The second driving member 432 can be a cylinder.

[0072] In this embodiment, if 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 at the initial position when grabbing 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.

[0073] In this embodiment, if Figures 7 to 9As shown, the distance between the first waiting position 45 and the second waiting position 46 is greater than 10 mm to ensure that the torsion spring transfer device 44 does not interfere with the torsion spring 104 at the first waiting position 45 when grasping the torsion spring 104 at the second waiting position 46. Preferably, the distance between the first waiting position 45 and the second waiting position 46 is greater than 15 mm or 20 mm.

[0074] In this embodiment, if 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 clamp.

[0075] In this embodiment, if Figures 6 to 21 As shown, the torsion spring acquisition 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 acquisition mechanism 50 can pass the pin through the buckle body pin hole and the buckle head pin hole 1031, and rivet them together using the pin riveting mechanism 60.

[0076] In this embodiment, if Figures 15 to 17 As shown, the pin acquisition mechanism 50 can utilize existing technology and will not be further elaborated here. For example, the pin acquisition mechanism 50 includes a pin conveying device 51 and a pin loading device 52; the pin conveying device 51 is used to convey pins; the pin loading device 52 is used to place the pins conveyed by the pin conveying device 51 into the pin holes 1031 of the buckle body and the buckle head.

[0077] In this embodiment, if Figures 15 to 17 As shown, the pin conveying device 51 includes a pin vibrating plate 511 and a pin conveying member 512. The pin vibrating plate 511 can convey pins to the pin conveying member 512. The pin feeding device 52 then installs the pins on the pin conveying member 512 into the pin holes in the buckle body and the buckle head 1031. A pin release member 513 is provided below the pin conveying member 512 to release the pins within the pin conveying member 512. When the pins are installed into the pin holes in the buckle body and the buckle head 1031, the pin release member 513 releases the pins from the pin conveying member 512. The pins are then guided by the pin feeding device 52 into the pin holes in the buckle body and the buckle head 1031. The pin vibrating plate 511, the pin conveying member 512, and the pin release member 513 can all be constructed using existing technologies, and their specific structures will not be further described here.

[0078] In this embodiment, if Figures 15 to 17As shown, the pin loading device 52 includes a pin guide 521 and a first pin driving member 522; the first pin driving member 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 conveying member 512 into the buckle body pin hole and the buckle head pin hole 1031.

[0079] In this embodiment, if 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, and then the pin guide 521 and the pin move away from the pin release member 513 and drive the pin into the buckle body pin hole and the buckle head pin hole 1031. The first pin driving member 522 can be a driving cylinder.

[0080] In this embodiment, if Figures 18 and 19 As shown, the pin riveting mechanism 60 can adopt existing technology and will not be further elaborated here. For example, the pin riveting mechanism 60 includes a pin punch 61 and a second pin driving member 62. The second pin driving member 62 drives the pin punch 61 to punch the pin so that the pin can be riveted into the pin hole of the buckle body and the pin hole 1031 of the buckle head. The pin riveting mechanism 60 also includes a pin pressing rod 65 and a third pin driving member 66; the third pin driving member 66 is installed on the frame and is used to drive the pin pressing rod 65 to press the pin so that the pin punch 61 can stably punch the pin. Among them, the pin pressing rod 65 and the pin punch 61 act on the two ends of the pin respectively.

[0081] In this embodiment, if Figures 18 and 19 As shown, the pin punch 61 is a rod-shaped structure; the second pin driving member 62 can be a pneumatic cylinder. The pin riveting mechanism 60 also includes a pin swing arm 63 and a pin base 64. The pin punch 61 is fixedly connected to the pin base 64. The pin swing arm 63 is rotatably mounted on the frame 10 about a predetermined axis. The second pin driving member 62 drives the punching swing arm 831 to swing, thereby driving the pin base 64, which in turn drives the pin punch 61 to punch the pin.

[0082] In this embodiment, if Figures 20 to 24As shown, the clamping fixture 12 also includes a buckle pusher 125, which is movably coupled to the base 121 via a buckle elastic member 126 and has a first position and a second position. The buckle elastic member 126 elastically supports and resets the buckle pusher 125. When the buckle pusher 125 is in the second position, the buckle pusher 125 compresses the buckle elastic member 126, and the buckle elastic member 126 forces the buckle pusher 125 to remain in the first position. When the buckle pusher 125 is in the second position, the buckle retrieval mechanism 70 transfers the buckle 106 to the base 121 or the buckle pusher 125. The buckle pusher 125 then pushes the buckle 106, driven by the buckle elastic member 126, until the buckle pusher 125 moves to the first position, allowing the buckle 106 to be assembled outside the buckle body 102 located on the base 121, thereby achieving automatic assembly of the buckle 106.

[0083] In this embodiment, if 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 is 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. Among them, 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 along the first direction.
