[0032] During specific implementation, after the parts are processed, the Swiss machine discharge pipe 201 automatically sends out the parts, and the parts are positioned at the bottom of the receiving box 202 under the action of the inclined surface of the receiving box 202. At this time, the opposing photoelectric switch 203 detects the parts, and the rodless cylinder 301 starts to drive the material shifting piece 302 to push the parts to the right end surface of the receiving box 202 and stop.

[0036] Working principle: After the parts are processed, the Swiss machine discharge pipe 201 automatically sends the parts out, and the parts are positioned at the bottom of the receiving box 202 under the action of the inclined surface of the receiving box 202. At this time, the photoelectric switch 203 detects the parts, and the rodless cylinder 301 starts to drive the material stripping piece 302 to push the parts to the right end surface of the receiving box 202 and stop. The material stripping piece 302 is driven by the rodless cylinder 301 to return to the initial position on the right side of the Swiss machine body 1. At this time, the in-place detection photoelectric switch 303 detects the parts, and the air claw 404 moves downward under the push of the lifting cylinder 402 and grabs two pieces and then rises. After rising into place, the part is rotated 180° under the action of the part rotation reversing cylinder 405 to achieve reversal. At this time, the lateral transfer rodless cylinder 401 transfers the parts to the top of the collecting hopper 6, and the air claw 404 releases the parts and falls into the collecting hopper 6.
