The stopper 122 and the stopper base member 123 are respectively provided with a cylindrical groove for accommodating a spring, and the spring is disposed in the cylindrical groove, whereby the deformation direction of the spring can be restricted, and the stable operation of the spring can be maintained. As shown in fig. 6, after the limiting member 122 is inserted downward onto the cover plate 121, a part of the limiting member 122 extends downward out of the cover plate 121, so that the limiting member 122 can press the plastic member and is held at this position by the elastic force of the spring. When the plastic part is moved in a staggered manner and moved to a position below the limiting part 122, the plastic part pushes up the limiting part 122, so that the limiting part 122 overcomes the elastic force of the limiting and resetting elastic part 124 and moves upward, and meanwhile, the limiting part 122 generates a reverse force for pressing down the plastic part, so that the plastic part is pressed and maintained at a preset position.

Principle of operation

The plastic parts are screened into an ordered state in a uniform directional arrangement by the plastic part material vibration disc 10, and enter the inlet section of the plastic parts from the first inlet 104 in sequence.

In the plastic inlet section, the plastic parts are arranged next to each other, and when the plastic parts move to the end of the plastic inlet section, the portion of the first plastic part is snapped into the notch of the blocking member 108, thereby stopping the movement.

When the plastic part dislocation line 102 needs to be picked up from the plastic part inlet section, the blocking driving device 106 moves the blocking member 108 through the adjustment of the sliding table module 107, so that the blocking member 108 retracts backwards and the clamping of the plastic part is released. The dislocation driving unit 109 drives a plastic part into the dislocation line 102 under the driving of the dislocation driving cylinder 111, and sets a mark when passing through the laser carving machine 12.

When the dislocation driving member 109 drives a plastic part to move forward by a preset distance, the plastic part needs to return to the original position to drive the next plastic part. During the return process, the slope structure at the back of the finger 113 contacts the plastic member, so that the finger 113 is driven to deflect on the base member 112, and can slide over the plastic member to the rear of the plastic member. When the shifting member 113 is moved forward again, the plastic member just slid can be driven forward by the vertical structure on the front side.

When the plastic part is driven to move to a preset position by the shifting part 113, the plastic part is temporarily fixed by the dislocation limiting mechanism, and the limiting part 122 presses the plastic part through the elastic force of the limiting and resetting elastic part 124, so that when the plastic part is in contact with the inclined surface structure of the shifting part 113, the elastic force of the shifting part resetting elastic part 114 can be overcome, and the shifting part 113 deflects; when the plastic part contacts with the vertical structure of the shifting member 113, the plastic part can overcome the elastic force of the limiting and resetting elastic member 124, so that the limiting member 122 slides upwards, and the fixation of the plastic part is released.
