[0035] During operation, the guiding device 7 guides the chain from the initial position on the chain guide slide 3 to the end position along the chain guide slide 3 and releases it, so that the middle position of the chain just reaches the position of the joint assembly mold 6 where the folding chain slide 4 and the chain guide slide 3 intersect. At this time, the chain folding device 5 set at the position of the folding chain slide 4 clamps the middle position of the chain and moves backward to perform the chain folding operation until the two ends of the chain reach the accurate position of the joint assembly mold 6.

[0036] Preferably, Figure 6 、 Figure 7 and Figure 8 As shown, the joint assembly mold 6 is provided with a retaining spring channel 6a and a connecting piece channel 6b. The position of the retaining spring channel 6a is lower than the position of the connecting piece channel 6b. The width and height of the retaining spring channel 6a are consistent with the width and thickness of the retaining spring 13, and the width and height of the connecting piece channel 6b are consistent with the width and thickness of the connecting piece 14.

[0037] More preferably, the retaining spring pushing mechanism 6e includes a retaining spring pushing piece 6e1, which is movably arranged in the retaining spring channel 6a, and the width and thickness of the retaining spring pushing piece 6e1 are consistent with the width and height of the retaining spring channel 6a, which is beneficial to the pushing effectiveness of the retaining spring 13, and the retaining spring pushing piece 6e1 is driven and connected to the output end of the retaining spring pushing servo motor 6e2 through a screw module; the contact piece pushing mechanism 6f includes a contact piece pushing piece 6f1, which is movably arranged in the contact piece channel 6b, and the contact piece pushing piece 6f1 is driven and connected to the output end of the contact piece pushing servo motor 6f2 through a screw module.

[0039] More preferably, the spring vibration conveying device 8 includes a spring vibration disk 8a and a first vibration seat 8b, the first vibration seat 8b sorts the springs in the spring vibration disk 8a and transmits them to the spring storage seat 8c set at the position of the spring channel 6a through the spring transmission guide; the splice vibration conveying device 9 includes a splice vibration disk 9a and a second vibration seat 9b, the second vibration seat 9b sorts the splices in the splice vibration disk 9a and transmits them to the splice storage seat 9c set at the position of the splice channel 6b through the splice transmission guide; the joint vibration conveying device 9 The feeding device 10 includes a joint vibration disk 10a, which is arranged at the center of the splice vibration disk 9a and shares the second vibration seat 9b with it. The joint vibration disk 10a sorts the joints therein and transmits them to the joint clamping, transmission and clamping mechanism 10b position through the joint guide rail. The spiral steel wire tracks arranged in the splice vibration disk 9a and the joint vibration disk 10a can be set in a clockwise direction or a counterclockwise direction, but the two share the second vibration seat 9b, so the directions of their spiral tracks must be consistent, thereby achieving the purpose of automatic feeding.

[0040] More preferably, Figure 11 As shown, the joint clamping, conveying and pressing mechanism 10b includes a joint clamping cylinder 10b-1, and a joint clamping head is provided at the output end of the joint clamping cylinder 10b-1. The joint clamping cylinder 10b-1 is arranged at the output end of the first up and down adjustment cylinder 10b-2. The first up and down adjustment cylinder 10b-2 is arranged at the output end of the rotating cylinder 10b-3 through a bracket, and the rotating cylinder 10b-3 is arranged at the output end of the left and right adjustment cylinder 10b-4. During operation, the joint clamping cylinder 10b-1 clamps the joint and lifts it through the first up and down adjustment cylinder 10b-2, then rotates 180 degrees through the rotating cylinder 10b-3, and finally pushes it to the left through the left and right adjustment cylinder 10b-4 and sends it to the assembly station. The first up and down adjustment cylinder 10b-2 descends again to install the joint into the chain link joint position. After completing the work, it returns to the initial position to perform the next wheel operation.

[0041] More preferably, Figure 13 and Figure 14As shown, a retaining spring transmission mechanism 8d is provided between the retaining spring vibration disk 8a and the retaining spring storage seat 8c, and the retaining spring transmission mechanism 8d includes a fixed bracket 8d1 and a retaining spring transmission rod 8d2. The retaining spring transmission rod 8d2 is connected to the fixed bracket 8d1 through a number of correcting connecting rods 8d3. One end of the retaining spring transmission rod 8d2 abuts against the output position of the retaining spring vibration disk 8a, and the other end of the retaining spring transmission rod 8d2 extends into the retaining spring storage seat 8c and is located on one side of the assembly station.

[0042] Since the hole on one side of the circlip 13 is open, the position where the circlip transmission rod 8d2 abuts against the output end of the circlip vibration disk 8a needs to be set to correct the connecting rod 8d3 connected to the fixed bracket 8d1 to fix it, guiding the notch hole of the circlip 13 and the circlip transmission rod 8b2 to go down in series. By the difference in diameter between the circlip transmission rod 8d2 and the opening hole of the circlip 13, the direction of the circlip is identified and defective products are prevented from entering the circlip storage seat 8c. Figure 14 As shown, the retaining springs 13 with the correct direction will be arranged in order on the retaining spring transmission rod 8d2 and transported to the retaining spring storage seat 8c position. At the same time, since the retaining spring transmission rod 8d2 is in a suspended state, the open end of the retaining spring 13 will always face upward after being sorted on the retaining spring transmission rod 8d2, and the unopened end will never be able to enter the retaining spring transmission rod 8d2. Finally, when it is transferred to the retaining spring storage seat 8c position, the opening direction is unified to the assembly station, and finally it is pushed to the assembly station for assembly through the retaining spring pushing piece 6e1 of the retaining spring pushing mechanism 6e.

[0043] More preferably, Figure 10 As shown, the feeding device 7 includes a feeding cylinder 7a, which is arranged on a first linear guide rail 7b on the workbench 1 and parallel to the chain guide slide 3 through a first slider.

[0045] Working process and steps:

[0046] 1. The spring vibrating conveyor 8 and the splice vibrating conveyor 9 respectively vibrate and sort the springs 13 and the splices 14, and respectively transfer them to the spring storage seat 8c and the splice storage seat 9c for storage. At the same time, the joint vibrating conveyor 10 also vibrates and sorts the joints 15, and transfers them to the joint clamping, conveying and pressing mechanism 10b for storage.

[0047] Second, the first servo drive motor 7c provided in the feeding device 7 drives the feeding cylinder 7a to pull the chain along the chain guide slide 3 to the required length. At the initial position, the feeding head 7a-1 at the output end of the feeding cylinder 7a extends to clamp the chain head. At the end position, the feeding head 7a-1 at the output end of the feeding cylinder 7a retracts to release the chain and returns to the initial position.

[0048] 3. The chain clamping cylinder 5a of the chain folding device 5 controls the chain clamping head set at its output end to clamp the middle position of the chain, and is driven by the second servo drive motor 5d to move backward until the two heads of the chain move to the intersection of the spring channel 6a and the splice channel 6b to form the assembly position, completing the chain folding work. The state of the chain after folding is as follows: Figure 15 The status shown is waiting for the next round of chain folding work;

[0049] Fourth, further, the spring pushing mechanism 6e drives the spring pushing piece 6e1 provided at its output end through the spring pushing servo motor 6e2 to push the spring 13 stored in the spring storage seat 8c to the intersection of the spring channel 6a and the connecting piece channel 6b to form the first predetermined position of the assembly station, and maintain it at this position, such as Figure 6 and Figure 15 At the same time, the tab pushing mechanism 6f drives the tab pushing piece 6f1 provided at its output end through the tab pushing servo motor 6f2 to push the tab 14 stored in the tab storage seat 9c to the intersection of the clamping spring channel 6a and the tab channel 6b to form an assembly station position.

Further, the control cylinder 6d2 of the positioning mechanism 6d drives the positioning column seat 6d1 and the positioning column 6d1-1 upward to penetrate into the holes of the retaining ring 13, the connecting piece 14 and the chain head for positioning, so as to facilitate the subsequent assembly work of the joint 15, such as Figure 8 Status shown;

[0051] 6. Furthermore, the joint clamping head provided at the output end of the joint clamping cylinder 10b-1 clamps the joint 15 and is lifted by the first up-and-down adjusting cylinder 10b-2, rotated 180 degrees by the rotating cylinder 10b-3, and finally pushed to the left by the left-and-right adjusting cylinder 10b-4 to the assembly station. The first up-and-down adjusting cylinder 10b-2 descends again to install the joint into the chain link joint position. During this process, the shaft at the lower end of the joint 15 corresponds to the position of the positioning column 6d1-1. At the same time, when pressing down, the control cylinder 6d2 drives the positioning column seat 6d1 and the positioning column 6d1-1 downward, wherein a reset spring is provided between the positioning column 6d1-1 and the positioning column seat 6d1 to act as a buffer to prevent the shaft at the lower end of the joint 15 from damaging the positioning column 6d1-1 and the positioning column seat 6d1.

[0052] 7. Furthermore, after the joint clamping head presses the joint 15 into place, the retaining spring pushing servo motor 6e2 further pushes the retaining spring 13 toward the assembly station position through the retaining spring pushing piece 6e1 until the retaining spring 13 is completely clamped in the retaining spring groove of the lower end shaft of the joint 15, completing the assembly work of the chain joint. Finally, the joint clamping, conveying and clamping mechanism 10b returns to its initial position, preparing for the next round of assembly tasks.
