Then the transport rod 9 will move to the right through the transport rod lateral movement mechanism 41, the moving distance is a distance of one station, and reach the bottom of the liquid spray mechanism 5. The conveying rod 4 is lowered, and the glass piece 9 is placed on the feeding support rod 11 again, and the nozzle of the liquid spraying machine head 5 sprays the cleaning liquid onto the surface of the glass piece 9.

[0071] Then, the conveying rod 4 floats up again, and continues to drive the glass piece 9 sprayed with the cleaning liquid on the surface to move to the right, and move to the top of the station area 101, and then the conveying rod 4 descends to place the glass piece 9 on the top of the station area 101 , The workbench air hole 100 on the work station area 101 causes the workbench air hole 100 to generate a negative pressure through a vacuuming device to adsorb the glass 9 to be wiped. Since the workbench 1 is covered with the lower wiping fabric, the negative pressure generated by the workbench air hole 100 will act on the glass 9 through the lower wiping fabric to fix it. At the same time, the upper wiping plate 201 of the upper wiping module 20 in the upper wiping mechanism 2 is pressed down by the upper wiping cylinder 202, and the upper wiping fabric passing by the bottom surface of the upper wiping plate 201 is pressed against the upper surface of the glass 9. At this time, the middle pressing rod 34 floats downward to press the lower wiping fabric against the surface of the worktable 1.

[0072] Then, the upper wiping mechanism 2 drives the upper wiping module 20 through the upper wiping drive mechanism to start moving in the front, back, left, and right directions on the horizontal plane, that is, to realize the operation in the X/Y axis direction, and perform the first operation on the glass piece 9 sprayed with the cleaning liquid. Road wiping process. After the wiping is completed, the upper and lower wiping fabrics that have been wiped need to be replaced. The present invention directly implements the replacement of the upper and lower wiping fabrics through the upper winding roll 25 and the lower winding roll 32. After the first wiping process is completed, the upper wiping plate 201 is floated up by the upper wiping cylinder 202 to make the bottom surface of the upper wiping plate 201 leave the upper surface of the glass member 9. At this time, the intermediate pressing rod 34 floats upward. The upper rewinding roll 25 and the lower rewinding roll 32 start to work, and the upper and lower wiping fabrics are moved to the right for one station, so as to realize the replacement of the wiping fabrics and ensure the cleanliness of the wiping.

[0073] Then, according to the above steps, the glass piece 9 is gradually moved to the station areas 102, 103, 104, and all the wiping processes are completed. As the glass piece 9 gradually moves to the right, its surface is gradually wiped clean.

[0074] Finally, after the glass piece 9 completes all the wiping processes, it is moved to the top of the discharging support rod 12 through the conveying rod 4, and the position of the glass piece 9 is corrected by the alignment mechanism 6, the wiping process is completed, and the glass piece 9 waits for the robot to grab , Into the subsequent process.
