[0067] The specific working principle of a spot welding device for automotive relays provided by the present utility model is as follows:

[0068] When using this device, when it is necessary to unwind the relay braided wire, the first driving motor 103 is started to drive the unwinding coil 102 to rotate. The braided wire is unwound by the unwinding mechanism and enters the tensioning mechanism, and winds around and passes through several tensioning guide wheels 108 therein. After being tensioned by the tensioning mechanism, the braided wire enters the receiving side spot welding mechanism and passes through the first mounting block 112;

[0069] When performing the receiving spot welding operation, the receiving positioning cylinder 113 will start to drive the receiving positioning block 114 to move, so that it cooperates with the receiving positioning plate 115 to hold the braided wire against it for positioning. Subsequently, the receiving spot welding cylinder 110 starts to drive the receiving spot welding head 111 to descend, and the spot welding head installed at the bottom of the receiving spot welding head 111 spot-welds a part of the braided wire for receiving;

[0070] After receiving, the braided wire passes through the conveying groove at the top of the feeding block 118. The second feeding cylinder 119 starts to drive the feeding head 120 to descend to press the braided wire for positioning. Subsequently, the first feeding cylinder 117 starts to drive the feeding block 118 to move, and the displacement movement of the feeding block 118 drives the braided wire to move. After the braided wire is conveyed by the feeding block 118, it passes through the cutting support block 125. Then the cutting cylinder 122 starts to drive the cutting mounting block 123 to descend, and further drives the cutting knife 124 to descend, and the braided wire is cut by the cutting knife 124;

[0071] When it is necessary to load the moving reed, the moving reed vibrating loading tray 213 vibrates and loads the moving reed. The first loading and transporting cylinder 215 starts to drive the first loading carrier 216 to approach the output end of the moving reed vibrating loading tray 213. There is a carrier groove on the top of the second mounting block 116, and the moving reed will be conveyed into the carrier groove on the top of the first loading carrier 216. Subsequently, the second loading and transporting cylinder 220 starts to drive the third mounting plate 221 to descend, and further drives the handling suction head 222 to descend, so that it moves to the position above the moving reed. Then the suction cylinder 228 starts to drive the magnetic head to descend, so that it contacts the moving reed and sucks the moving reed. Subsequently, the second loading and transporting cylinder 220 starts again to drive the moving reed to rise. Then the first loading and transporting cylinder 218 starts to drive the second mounting plate 219 to move, and further drives the moving reed to move, so that it moves above the corresponding first spot welding carrier 211. Subsequently, the second loading and transporting cylinder 220 starts again to drive the moving reed to descend, and places the moving reed on the corresponding first spot welding carrier 211. Then the suction cylinder 228 starts to drive the magnetic head to retract inside the handling suction head 222 to put down the moving reed in this way. Subsequently, the second loading and transporting cylinder 220 and the first loading and transporting cylinder 218 start again to return to the initial position to complete the loading of the moving reed;

[0072] The braided wire is cut after entering the inside of the first spot welding carrier 211. At this time, there is a moving reed inside the first spot welding carrier 211. When it is necessary to spot-weld the moving reed and the braided wire together, the first moving reed spot welding cylinder 202 starts to drive the first spot welding block 203 to move downward, and further drives the first spot welding head 204 to descend. At the same time, the second moving reed spot welding cylinder 205 starts to drive the second welding block 206 to move upward, and further drives the second spot welding head 207 to rise, and the braided wire and the moving reed are spot-welded by the first spot welding head 204 and the second spot welding head 207;
