[0046] Working principle:

[0047] The carrier 02 moves to the loading position, and the arc groove h1 set on the right shift limit plate 04312 corresponding to the loading position limits the front, back, left and right positions of the carrier 02. Then the wire is clamped into the tooth groove 024 of the carrier 02, and the right shift cylinder 04313 of the right shift mechanism 043 extends out, and the right shift push block 04318 moves to the left. The right shift push block 04318 pushes the carrier 02 to move to the left and stops on the next arc groove h1 of the right shift limit plate 04312. Then the right shift mechanism 043 is reset. The lifting and locking cylinder 040441 of the rear middle shift mechanism 044 is actuated to drive the lifting and locking block 040442 to enter the first groove c1 to realize the connection between the lifting and locking assembly 04414 and the carrier 02. Then the screw rod shift assembly 04412 drives the carrier 02 to move left to the terminal punching position. Then the terminal machine 5 works to crimp the terminal on the wire. After the terminal punching is completed, the first carrier front and rear shift assembly 04415 is actuated to move the carrier 02 in the opposite direction to the terminal machine 5 to avoid the terminal machine 5. Then the screw rod shift assembly Component 04412 drives carrier 02 to move to the left shift mechanism 045, the left shift cylinder 04513 of the left shift mechanism 045 extends, the left shift push block 04518 moves to the left, and the left shift push block 04518 pushes carrier 02 to move to the left, and then moves to the plug-in shell station, and then the wire clamping and positioning mechanism 6051 pre-clamps the wire, and then the second carrier forward and backward shift component 04520 is actuated to move carrier 02 in the opposite direction to the plug-in shell mechanism 6. During the movement, the wire clamping and positioning mechanism 6051 The wire straightening mechanism 60511 straightens the wire, and then the wire clamping and positioning mechanism 6051 clamps the wire again, and then the clamping and positioning mechanism 60512 clamps and positions the terminal on the wire, and then the plastic shell removal mechanism 6041 inserts the plastic shell onto the wire, and then the left shifting mechanism 045 operates again to move the carrier 02 to the left lifting mechanism 05, and the wire clamping assembly 7001 of the unloading mechanism 7 on the left lifting mechanism 05 clamps the wire, and then the left lifting mechanism 05 descends, and at the same time, the carrier 02 is separated from the wire.
