The second rack 6133 is connected to the cutter connecting member 614. The driving gear 6131 meshes with the first rack 6132 and the second rack 6133. When the cutter driving member 612 is started, the driving gear 6131 rolls in the first rack 6132 and the second rack 6133, and drives the upper cutter 615 connected to the first rack 6132 to move up and down.

[0056] Please review Figure 10 , as shown in the figure, the wire stripping group 62 includes an upper wire stripping knife 621 and a lower wire stripping knife 622. The upper wire stripping knife 621 is connected to the upper cutter 615. The lower wire stripping knife 622 is connected to the cutter connecting member 614. The height of the cutting edge of the upper wire stripping knife 621 is higher than the height of the cutting edge of the upper cutter 615. The height of the cutting edge of the lower wire stripping knife 622 is lower than the height of the cutting edge of the lower cutter 616.

[0057] Please review Figure 9, as shown in the figure, the air blowing group 63 includes an air blowing joint fixing plate 631 and an air blowing joint 632. The air blowing joint fixing plate 631 is arranged on the cutter connecting piece 614. The air blowing joint fixing plate 631 is provided with air holes penetrating through the air blowing joint fixing plate 631, and the air blowing joint 632 is arranged at one end of the air holes. The air holes are aligned with the positions between the upper cutter 615 and the lower cutter 616. During operation, the air blowing joint 632 can be connected to an air pump. When the wire passes through between the upper cutter 615 and the lower cutter 616, the cutter driving piece 612 drives the upper cutter 615 to move towards the lower cutter 616, first cutting the wire sheath on the wire to form a first incision; then the moving group 53 drives the wire to move forward a certain distance towards the welding assembly 2. After that, the cutter driving piece 612 drives the upper cutter 615 to move towards the lower cutter 616 again, cutting the wire sheath on the wire to form a second incision; again, then the moving group 53 drives the wire to move backward a certain distance towards the welding assembly 2, so that the upper cutter 615 and the lower cutter 616 are located between the first incision and the second incision; finally, the cutter driving piece 612 drives the upper cutter 615 to move towards the lower cutter 616 to cut off the wire; at the same time, since the upper wire stripping knife 621 and the lower wire stripping knife 622 press on the wire sheath, when the wire leaves the cutting assembly 6, the wire sheath is pulled down from the wire at the cut section; then the cutter driving piece 612 drives the upper cutter 615 and the upper wire stripping knife 621 to reset, and at the same time the air blowing group 63 blows air on the wire located between the upper cutter 615 and the lower cutter 616, so that the wire sheath at the wire head falls off from the wire.

[0058] Please review Figure 1 , as shown in the figure, in order to integrate the fixture assembly 1, the welding assembly 2, the conductive ring feeding assembly 4, the wire feeding assembly 5 and the cutting assembly 6 together, in this embodiment, the welding device of the present application further includes a frame 7, and the fixture assembly 1, the welding assembly 2, the conductive ring feeding assembly 4, the wire feeding assembly 5 and the cutting assembly 6 are arranged on the frame 7.

[0059] Please review Figure 1 , as shown in the figure, in this embodiment, the frame 7 is provided with a material receiving groove 71. The material receiving groove 71 is located below the wire arranging group 14. The frame 7 is provided with a wire dropping groove located below the wire arranging group 14. After the conductive ring welded to the wire is fed, it falls along the wire arranging group 14 and falls into the material receiving groove 71 through the wire dropping groove for centralized storage.

[0060] In this embodiment, the welding assembly 2, the conductive ring feeding assembly 4, the wire feeding assembly 5 and the cutting assembly 6 are electrically connected to the control system of the welding device, and the control system of the welding device controls the operation of the welding assembly 2, the conductive ring feeding assembly 4, the wire feeding assembly 5 and the cutting assembly 6 to achieve the effect of automatic control of the welding device.

[0061] Specific applications:

[0062] First, the conductive ring feeding component 4 conveys the conductive ring to the feeding groove 111 on the fixture 11. When the conductive ring is conveyed by the feeding groove 111 to the lifting groove 113, the conductive ring enters the lifting groove 113 and falls above the lifting member 32. The lifting driving member 31 drives the lifting member 32 to move upward along the lifting groove 113. The lifting member 32 jacks up the conductive ring from the bottom of the conductive ring, and lifts the conductive ring to the intersection of the lifting groove 113 and the avoidance groove 112.

[0063] Meanwhile, the wire feeding component 5 is activated. The pressing group 51 presses the wire, and then the moving group 53 drives the pressing group 51 and the feeding group 52 to move towards the welding component 2. When the wire passes between the upper cutting knife 615 and the lower cutting knife 616, the cutting knife driving member 612 drives the upper cutting knife 615 to move towards the lower cutting knife 616, first cutting the wire skin on the wire to form a first incision. Then the moving group 53 drives the wire to advance a certain distance towards the welding component 2. After that, the cutting knife driving member 612 drives the upper cutting knife 615 to move towards the lower cutting knife 616 again, cutting the wire skin on the wire to form a second incision. Then the moving group 53 drives the wire to retreat a certain distance from the welding component 2, so that the upper cutting knife 615 and the lower cutting knife 616 are located between the first incision and the second incision; and the front end of the wire is placed on the inner wall of the conductive ring. Finally, the welding component 2 and the cutting component 6 are activated simultaneously. The welding head driving group 21 drives the welding head 22 to move downward, and the lower surface of the second part 222 presses on the wire placed on the inner wall of the conductive ring. The second part 222 of the welding head 22 discharges electricity to weld the conductive ring and the wire. At the same time, the cutting knife driving member 612 drives the upper cutting knife 615 to move towards the lower cutting knife 616 to cut the wire; at the same time, since the upper peeling knife 621 and the lower peeling knife 622 press on the wire skin of the wire, when the wire leaves the cutting component 6, the wire skin is pulled off from the wire tail of the cut wire. Then the cutting knife driving member 612 drives the upper cutting knife 615 and the upper peeling knife 621 to reset. At the same time, the blowing group 63 blows air on the wire located between the upper cutting knife 615 and the lower cutting knife 616, so that the wire skin at the wire head falls off from the wire.

[0064] Finally, the lifting driving member 31 drives the lifting member 32 to move upward along the lifting groove 113. The lifting member 32 jacks up the conductive ring from the bottom of the conductive ring. Then the welding head driving group 21 drives the welding head 22 to move upward to unload the conductive ring from the fixture. After the conductive ring welded to the wire is unloaded, it falls along the wire arranging group 14 and falls into the receiving groove 71 from the wire dropping groove for centralized storage.

[0065] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements or improvements made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
