[0036] Feeding and conveying: After the dispensing workpiece is fixed on the product placing table 2, the conveyor 1 uniformly conveys it to the dispensing station.

[0037] Precise positioning: After the photoelectric sensor 3 detects that the workpiece reaches the predetermined position, the cylinder 4 is triggered to push the limiting baffle 5 to fix the workpiece. At the same time, the three-dimensional guide rail 7 drives the dispensing table 8 to move to the initial coordinates.

[0038] Image recognition and path planning: The high-definition camera 9 takes pictures of the workpiece, and the PLC controller 16 identifies the workpiece contour through image processing technology, automatically generates a dispensing path and optimizes the motion trajectory.
