When the air clamp 23 is unfolded, the farthest end of its clamping plate 231 is closer to the center column 13 than the point of a workpiece slot 11 closest to the center column 13, that is, if Figure 3As shown in the figure, a certain air clamp 23 corresponds to a workpiece slot 11. When the air clamp 23 is unfolded, it is located outside the area directly above the workpiece slot 11 indicated by the dotted line. When the air clamp 23 is clamped, the farthest end of its clamping plate 231 is located within the area directly above the workpiece slot 11.

Preferably, the port of the vacuum suction hanger 28 for connecting the vacuum tube faces outward along the radial direction of the disc portion 1 to facilitate the connection of the pipeline. During operation, the annular guide rail 14 can rotate in the opposite direction after rotating one circle to avoid entanglement of the pipeline.

[0025] After coating one side, start the vacuum lifter 28, then lift multiple workpieces through the linear mechanism 26, then clamp the workpieces through the air clamp 23, and then close the vacuum lifter 28, and rotate the workpiece 180° through the rotating motor 22. At this time, the gear 24 drives the other gears 24 to rotate 180°, and the rotating rod 25 rotates the other workpieces 180°.

[0026] Then, the vacuum lifter 28 and the air clamp 23 are used again to release the workpiece, and then the linear mechanism 26 puts down the workpiece.
