[0060] The linear module 3 drives the workpiece on the workpiece positioning platform 4 to move and transport the workpiece to the cleaning position. The plasma cleaning head 71 is connected to a high-pressure pump through a pipeline. The high-pressure pump extracts plasma water and sprays it out under pressure to start cleaning the surface of the workpiece.

[0061] Step 3: Glue application:
