[0035] The implementation principle of a fully automatic multi-wire tinning terminal machine in the embodiment of the present application is as follows: when using the tinning terminal machine, first start the machine body 1 to perform the tinning operation of the wire harness, and at the same time start the driving member 5 to drive the active gear 71 to rotate, the active gear 71 drives the driven gear 72 to rotate through the driving chain 73, and the driven gear 72 drives the rotating sleeve 81 to rotate, and the rotating sleeve 81 is limited by the sliding key 82 and the sliding groove, so that the rotating sleeve 81 drives the stirring shaft 41 to rotate, and the stirring shaft 41 drives the stirring impeller 42 to spirally stir the tin liquid in the inner box 22 to prevent the tin liquid from precipitating; at the same time, when the rotating sleeve 81 rotates, it drives the first gear 61 in the outer box 21 to rotate, the first gear 61 drives the third gear 91 to rotate through the first chain 94, and the third gear 91 drives the intermediate rotating shaft 93 to rotate, thereby driving the fourth gear 92 to rotate, and the fourth gear 92 drives the second gear 62 to rotate through the second chain 95, and the second gear 62 drives the lead screw 31 to rotate in the lifting groove, and the rotation of the lead screw 31 drives the slider 32 to slide in the lifting groove. Since the slider 32 is fixedly connected to the inner box 22, the slider 32 drives the inner box 22 to rise and fall in the outer box 21. As the inner box 22 slides in the outer box 21, the inner box 22 drives the stirring shaft 41 to slide in the rotating sleeve 81, and the stirring shaft 41 drives the sliding key 82 to slide in the sliding groove, so that the tin liquid keeps stirring the stirring impeller 42 in a unit time. At the same time, the rotating sleeve 81 drives the lead screw 31 to rotate a corresponding number of circles through the reduction assembly 9, so that the lead screw 31 drives the slider 32 to slide upward to a corresponding height, and the slider 32 drives the inner box 22 to slide up to a corresponding height, so that the sliding height of the inner box 22 is the same as the height of the liquid level drop of the tin liquid in the inner box 22, so that when other operations in the tin terminal machine are inconvenient, the tinning height of the wire harness is always consistent, thereby achieving the purpose of improving the tinning quality of the wire harness.
