[0002] Electronic connecting wires are conductive cables used to connect circuit elements, devices or electronic components. They can transmit current, signals and data. Electronic connecting wires need to be welded during processing. Traditional welding is mostly performed in the form of soldering.

Subsequently, the first motor 562 is controlled to start and drive the driving gear 563 to drive the crown gear 561 to rotate, thereby driving the double-headed screw 56 to rotate, and then controlling the longitudinal slide 54 and the L-shaped slide 53 to move toward each other. The welding head 55 and the tin wire output mechanism 551 move toward each other with the welding base 51, and the welding base 51 contacts the connection positions on both sides for support.

Subsequently, the first motor 562 is controlled to start to drive the driving gear 563 to drive the crown gear 561 to rotate in the opposite direction, thereby driving the double-headed screw 56 to rotate in the opposite direction, and controlling to drive the welding head 55 and the tin wire output mechanism 551 to move in the opposite direction with the welding base 51 to reset, thereby realizing automatic welding and fixation of the electronic connecting wires on both sides.

[0039] Working principle: When in use, the electronic connecting wires to be connected are placed on the material placing frames 254 of the corresponding two transmission mechanisms 2; Subsequently, the second motor 10 is controlled to start driving the corresponding transmission shaft 23 in one of the transmission mechanisms 2 to rotate, and the corresponding transmission shaft 23 in the other transmission mechanism 2 is driven to rotate in coordination with the connection of the co-drive shaft 9, thereby driving the transmission sprocket 24 to control the transmission chain 241 to transmit, thereby synchronously controlling the multiple material placement parts 25 in the two transmission mechanisms 2 to transmit synchronously, and then synchronously driving the electronic connection lines on both sides to transmit; First, it is transmitted to the position of the skin breaking mechanism 4, and the positioning mechanism 6 at this position is controlled to open the second lifting cylinder 62 to drive the horizontal sliding sleeve frame 63, the inner slide 64, the pressing block 65, and the pressing sleeve 66 to descend, and the pressing block 65 with the pressing sleeve 66 is inserted into the corresponding material placing frame 254 to position the electronic connecting wire placed in the material placing frame 254; Then, the first lifting cylinder 42 is controlled to drive the second horizontal sliding frame 43, the first tool holder 44 and the second tool holder 45 to move upward, so that the electronic connection line is placed between the skin-breaking grooves 401 of corresponding sizes. Then, the first telescopic rod 46 is controlled to drive the second tool holder 45 close to the first tool holder 44, and the skin-breaking part of the electronic connection line is stuck in the skin-breaking groove 401; Subsequently, the first guide rod 74 is controlled to be extended and retracted, driving the fourth frame 73, the first guide rod 74 and the outer protruding rod 741 to move. The outer side of the first guide rod 74 first contacts the ball 255 in the corresponding material placement piece 25, and then the outer side of the outer protruding rod 741 contacts the ball 255 in the corresponding material placement piece 25. The outer protruding rod 741 abuts against the ball 255 in the corresponding material placement piece 25, driving the ball 255 to translate, driving the material placement frames 254 in the corresponding material placement pieces 25 on both sides to move backwards. Since the inner slide 64 is inserted in the middle of the horizontal sliding frame 63, when the material placement frame 254 moves horizontally, the inner slide 64 can be controlled to slide in the middle of the horizontal sliding frame 63, so that the pressing block 65 always positions the electronic connection line in the material placement frame 254. By controlling the electronic connection wires on both sides to move in opposite directions, the electronic connection wires are separated from the first tool holder 44 and the second tool holder 45, and the ends of the electronic connection wires are automatically broken; Subsequently, the outer side of the first guide rod 74 at the other end position contacts the ball 255 in the corresponding material placement piece 25, and the material placement frame 254 in the material placement piece 25 is reset. Subsequently, the second lifting cylinder 62 is controlled to start driving the horizontal sliding sleeve frame 63, the inner slide 64, the pressing block 65, and the pressing sleeve 66 to move upward, and the electronic connection line loses its position; Subsequently, the electronic connection wire is continuously transmitted to the position of the welding mechanism 5. The ball 255 in the material placement member 25 first contacts the inner side of the second guide rod 82, and then contacts the inner side of the inner convex rod 821. The inner convex rod 821 abuts against the corresponding ball 255 to drive the ball 255 to translate, driving the material placement frames 254 in the corresponding material placement members 25 on both sides to move toward each other. The electronic connection wires after the skin is broken on both sides move toward each other, and the connection positions contact each other. Then, the positioning mechanism 6 at this position is controlled to position the electronic connection wire. Subsequently, the first motor 562 is controlled to be turned on to drive the driving gear 563 to drive the crown gear 561 to rotate, thereby driving the double-headed screw 56 to rotate, and then controlling the longitudinal slide 54 and the L-shaped slide 53 to move toward each other, thereby driving the welding head 55 and the tin wire output mechanism 551 and the welding base 51 to move toward each other, the welding base 51 contacts the connection positions on both sides for support, the welding head 55 contacts the connection positions on both sides, cooperates with the tin wire output mechanism 551 to output tin wire, the welding head 55 melts the tin wire, and the molten tin liquid welds the connection positions on both sides, then, the first motor 562 is controlled to be turned on to drive the driving gear 563 to drive the crown gear 561 to rotate in the opposite direction, thereby driving the double-headed screw 56 to rotate in the opposite direction, and controlling to drive the welding head 55 and the tin wire output mechanism 551 and the welding base 51 to move back to reset, thereby realizing automatic welding and fixing of the electronic connecting wires on both sides; Subsequently, the positioning mechanism 6 is reset, the electronic connection lines on both sides lose their positioning, and the electronic connection lines on both sides continue to be transmitted, the outer side of the first guide rod 74 at the other end position contacts the ball 255 in the corresponding material placement member 25, and the material placement frame 254 in the material placement member 25 is reset; Until the connected electronic connecting wires on both sides are transmitted to the end, the electronic connecting wires automatically fall off the material placement part 25 for automatic unloading, so as to carry out subsequent processing of the electronic connecting wires.
