Description
Technical Field

[0031] Furthermore, the feeding conveyor belt 3 operates, effectively conveying flat workpieces. During the movement of the flat workpiece, it can be effectively locked into the flipping frame 604 and limited by the push plate 607. Then, the stepper motor 601 operates, flipping the flipping frame 604 180°, effectively flipping the flat workpiece. Then, the cylinder 605 operates, effectively pushing the flipping frame 604 to the feeding conveyor belt 4 via the push plate 607, conveying it away for the next step of reverse spraying. Then, the flipping frame 604 flips 180° in the opposite direction to return to its original position, performing the next flipping action. This cycle continues, and the overall operation is simple.
