The terminals on the feed rail 900 may be individually brought into the processing station 150 at a time by the kick-out mechanism 200. After the terminal is transported to the processing station 150, the positioning mechanism 500 can position the terminal and the wire guide 600 can also position the wire. This achieves the effect of positioning both the terminal and the wire at the processing position 150, and ensures that the press-molding of the terminal and the wire can be accurately performed when the press mechanism 300 performs the press-molding. Since the terminal and the wire have each completed the relative positioning effect with the processing site 150 when being conveyed to the processing site 150, there is no need to perform positioning detection again by means of visual detection or the like, so that the cost of the part can be effectively saved, and the advantage in terms of processing cost is brought. In addition, the positioning operation is completed in the conveying process without additional positioning processing, so that the operation efficiency can be effectively improved.

In some embodiments, referring to fig. 2, the material stirring mechanism 200 includes a material stirring cylinder 210 disposed on the base 100, where the material stirring cylinder 210 is connected to a first fork 220; the feeding track 900 can drive the terminals to move towards the processing station 150; the first fork 220 is capable of moving into the feed rail 900 and preventing further movement of the terminals on the feed rail 900. The feeding track 900 carries each material together, and after the material shifting cylinder 210 is started, the first shifting fork 220 can be driven to move and extend into the feeding track 900 and extend between the terminals, so that the first shifting fork 220 can block the material before the first shifting fork, and the material behind the first shifting fork 220 can continue to move. Therefore, the first shifting fork 220 can repeatedly block the single terminals, so that the difference of the movement rates among the terminals on the feeding track 900 is realized, the effect that the terminals enter the processing position 150 one by one can be smoothly realized, and the processing position 150 can smoothly carry out crimping operation on the terminals.

Specifically, a position sensor is disposed on the feeding rail 900, and when the first fork 220 extends into the feeding rail 900, the position sensor can detect the position of the first fork 220, so as to ensure that a single terminal is continuously driven by the feeding rail 900 and moves to the processing position 150 each time the first fork 220 extends into the feeding rail 900 and leaves the feeding rail 900.

When the first fork 220 extends into the feeding rail 900 and shields the terminal in front of the first rail, the second fork 230 will leave the feeding rail 900 due to the opposite movement directions of the second fork 230 and the first fork 220, and the terminal between the first fork 220 and the second fork 230 can continue to move toward the processing station 150. Since the gap between the first end 225 and the second end 235 is adapted to a single terminal, the number of terminals between the first fork 220 and the second fork 230 is only one, and when the first fork 220 and the second fork 230 alternately extend into the feeding rail 900, the single terminal can be continuously moved toward the processing station 150, thereby directly and effectively achieving the purpose of conveying the single terminal to the processing station 150 and providing convenience for subsequent processing.
