The limit device is used to limit the bottom end of the cable. The stripping device realizes automatic stripping, and the tinning device is provided with automatic tinning.

[0022] Secondly, the second electric telescopic rod 110 is fixedly connected to the positioning seat 106 and is located at the bottom of the positioning seat 106. The limiting plate 111 is threadedly connected to the output end of the second electric telescopic rod 110, and is slidably connected to the positioning seat 106, and is located above the output end of the second electric telescopic rod 110. The second electric telescopic rod 110 is mounted on the hanging plate of the positioning seat 106 via bolts.

[0025] When using the present utility model to achieve automatic cable stripping, twisting and tin plating, which is beneficial to reducing the manual labor intensity and improving the processing efficiency, during processing, first, the second electric telescopic rod 110 operates to push out the limit plate 111, and then the cable is vertically placed into the guide sleeve of the positioning seat 106. The bottom of the cable is limited by the limit plate 111 to ensure its precise cooperation with the tool holder 114. Further, the clamping assembly 109 at the top of the positioning seat 106 operates to clamp the cable. Then, the screw rod sliding table 103 operates to move the positioning seat 106 to the top of the stripping device. Then, the second electric telescopic rod 110 resets, and the first electric telescopic rod 107 operates to push the cable downward. Then, the third electric telescopic rod 113 operates to push the tool holder 114 closer. At this time, after the tool holders 114 abut against each other, a circular cutting cavity can be formed by the inner blade parts. The size of the cutting cavity is just the size of the inner wire core of the cable, so that the cable sheath can be cut. Then, the first electric telescopic rod 107 operates. At this time, because the clamping assembly 109 is not loosened, the cable can be lifted upward, so as to perform stripping. After stripping, the screw rod sliding table 103 and the first electric telescopic rod 107 cooperate to move the cable to the wire twisting head machine body 102 to twist the end wire core tightly. Finally, the cable is moved to the tin plating device for tin plating. After tin plating, the first electric telescopic rod 107 moves upward and resets. After the clamping assembly 109 is loosened, the cable can be taken off, thus solving the problems that traditional cable stripping, wire twisting and tightening, and tin plating are mostly operated manually, with cumbersome operations, low production efficiency, and high labor intensity.
