A plurality of plastic parts are transported to the position of a stopper on a guide plate along with an assembly line. The plastic parts flow sequentially on a material guide trough by the cooperation of a first cylinder and a second cylinder driven by a translation cylinder. The clamping part of the grid plate first approaches the material guide trough to clamp the first plastic part. Then, the translation cylinder drives the second cylinder to move in the direction of the material guide trough away from the stopper.

[0033] In this embodiment, the plastic part 8 includes a step portion 81 and an annular ring 82 surrounding the step portion 81. The height of the step portion 81 is lower than the height of the annular ring 82. In this embodiment, the characteristic height difference of the plastic product refers to the height of the step portion 81 relative to the annular ring 82. The annular ring 82 of the plastic part 8 is arranged facing the displacement detector 7.

[0034] Specifically, in this embodiment, the feeding assembly 2 includes a guide plate 21 and a block 22 that can accommodate multiple plastic parts 8. The guide plate 21 includes a linear segment and a straight segment. The straight segment is close to the block 22. The inner diameter of the straight segment can only accommodate a single plastic part 8. The block 22 is connected to the material guide trough 3. The plastic part is first in the linear segment and then enters the straight segment. A single plastic part 8 can enter the material guide trough 3 from the guide plate 21 through the block 22.
