[0060] A first detection sensor is fixed on the welding cutting device 8, and the first detection sensor is used to detect whether the clamp 6 moves to the welding position. When the clamp 6 moves to the welding position, the first linear drive device 83 drives the upper limit assembly 82 to the mold closing welding position.

The lower welding connector seat 812 is provided with a connecting hole 813 for the upper welding connector 823 to extend into. When the upper welding connector 823 extends into the connecting hole 813, a welding limit groove corresponding to the number of conductive groups is formed between the upper limit assembly 82 and the lower limit assembly 81. The welding part of the wire 3 and the conductive connecting sheet 2 is located in the welding limit groove, and only when the upper welding connector 823 extends into the connecting hole 813, the lower welding connector seat 812 heats the wire 3 or the conductive connecting sheet 2 to weld the two into one.

[0064] Since the wire 3 and the conductive connecting piece 2 are firmly fixed and pressed between the lower limit assembly 81 and the upper limit assembly 82, the welding and cutting device of this embodiment can be used for Figure 6The wire 3 and the conductive connecting piece 2 fixed by the clamp are stably welded and can achieve a 100% welding success rate, but it is not possible to Figure 1 In the prior art shown, the wire 3 is welded to the conductive connecting piece 2 fixed on the base 1. Because the angle and space of the welding operation are limited by the base 1, the wire 3 and the conductive connecting piece 2 fixed on the base 1 cannot be welded after being clamped as shown in this embodiment.

[0065] like Figure 5 As shown, the annular conveying device 71 is a circular rotating disk, and the first rotating driving device 72 is a rotating motor connected to the bottom of the circular rotating disk.

[0068] When the reversing assembly 9 is in the reversing position, Fig.12 As shown, the movable spring piece 4 and the conductive connecting piece 2 are reversed so that the movable spring piece 4 and the conductive connecting piece 2 are vertically fixed, the first clamping device 91 and the second clamping device 94 respectively complete the rotation in different rotation directions through the second rotating device 92 and the third rotating device 95, and when the first clamping device 91 completes the linear displacement through the second linear driving device 93, it approaches the second clamping device 94.

[0069] like Figure 5As shown, the reversing assembly 9 is connected to a third linear drive device 11, and the third linear drive device 11 is used to drive the reversing assembly 9 to approach the annular conveying device 71 or to move away from the annular conveying device 71, so that the reversing assembly 9 can reverse the dynamic spring piece 4 and the conductive connecting piece 2 after completing the material collection at the material collection position and moving away from the annular conveying device 71. This can improve work efficiency.

[0070] like Fig.13 As shown, the assembly component 10 is arranged corresponding to the reversing component 9 that has completed the reversing position, and the assembly component 10 includes a third clamping device 101 and a fourth clamping device 102 that respectively correspond to the first clamping device 91 and the second clamping device 94 of the reversing component 9 that has completed the reversing position, and a driving device for moving the third clamping device 101 and the fourth clamping device 102 so that they move between clamping the movable reed piece 4 and the conductive connecting piece 2 that have completed the reversing and plugging them into the relay base.

[0071] Further, such as Figure 4 As shown, the conductive connecting piece 2 is provided with a limiting protrusion 22 close to the portion welded to the wire 3 and a portion to be punched and riveted located at a certain distance (greater than the thickness of the portion of the base where the conductive connecting piece 2 is installed) from the lower end of the limiting protrusion 22, the portion to be punched and riveted is a groove 23 integrally formed on the conductive connecting piece 2 and a limiting block 24 located in the groove 23, the assembly equipment also includes a punching and riveting device for applying force to the limiting block 24 of the conductive connecting piece 2 inserted in the base 1 to make it bend, after the punching and riveting device is set in the assembly component 10, the assembly component 10 inserts the conductive connecting piece 2 into the base 1, and the limiting protrusion 22 abuts against the inner wall of the base 1 so that the limiting block 24 is located below the base 1, and the limiting block 24 is bent by applying force to the limiting block 24 through the punching and riveting device, so that the conductive connecting piece 2 cannot be pulled out, and the punching and riveting device can be realized by using a conventional automatic driving mechanism in combination with an operating end structure that is compatible with the shape of the portion to be punched and riveted of the conductive connecting piece 2.
