[0049] The implementation principle of this application is as follows:

[0050] After the first material receiving tray 22 receives the workpieces from the previous process at the initial position, the workpieces are adsorbed by the suction nozzles on the first material placement positions 27, and move with the first material receiving tray 22 under the first mounting seat 301. The first material receiving tray 22 is located between two first guide rollers 34. The first material placement positions 27 are first opposite to the pressing blocks 303 in the front row. The spray pipe 304 sprays water on the wiping cloth 39. The first mounting seat 301 moves towards the wiping cloth 39 between the first guide rails 3024 driven by the first lifting control assembly 302 until the pressing blocks 303 press the wetted wiping cloth 39 against the workpieces on the first material placement positions 27. The pressing blocks 303 rotate forward and backward to wipe the top surfaces of the workpieces. Then the first mounting seat 301 rises, and the first material placement positions 27 move under the pressing blocks 303 in the rear row. The first mounting seat 301 descends again, and the pressing blocks 303 in the rear row press the dry wiping cloth 39 against the workpieces to dry-wipe the workpieces.

[0051] After the cleaning of the top surface is completed, the first mounting seat 301 rises, and the first material receiving tray 22 moves under the suction pen 203. The suction pen 203 sucks up the workpieces on the first material placement positions 27. The first material receiving tray 22 returns to the initial position to receive new workpieces. The second material receiving tray 23 moves under the suction pen 203. The suction pen 203 places the workpieces on the second material placement positions 28, and the suction nozzles adsorb the workpieces on the second material placement positions 28.

[0052] The second material receiving tray 23 moves the workpieces under the second mounting seat 311. The ejector rod 313 is tangent to the side surfaces of the workpieces. The second mounting seat 311 moves towards the wiping cloth 39 between the second guide rollers 35 under the action of the second lifting control assembly 312. The ejector rod 313 presses down on the wiping cloth 39 to make the wiping cloth 39 contact the side walls of the workpieces. The rotating seat 29 rotates, and the workpieces rotate on their own. The wiping cloth 39 wipes the side walls of the workpieces. After the cleaning of the side surfaces is completed, the second mounting seat 311 rises, and the second material receiving tray 23 moves the workpieces towards the next process. During the cleaning process, the wiping cloth 39 is automatically updated between the winding roller 32 and the unwinding roller 33.

[0053] This application can quickly clean the side surfaces and top surfaces of small thin-plate workpieces such as watch glass panels. During the top surface cleaning, the spray pipe 304 is arranged between two rows of pressing blocks 303. The dry-wiping structure and the wet-wiping structure are integrated together, and the top surfaces of the workpieces are cleaned by combining dry-wiping and wet-wiping, improving the cleaning efficiency of the workpieces.
