Currently, the optical film is taken out of the upper bin 101 and placed onto the grinding station of the grinder 102 mainly manually in the grinding system, and after the grinder 102 grinds the optical film, the optical film is retrieved from the grinding station of the grinder 102 and placed into the lower bin 103. In addition, after the optical film is ground by the grinder 102, the optical film also needs to be manually ground and cleaned by a human to remove burrs and chips. In the process, the processing error rate is high, the efficiency is low, and the labor cost is high.

For this purpose, the utility model introduces an automation aid in the grinding system. As further shown in fig. 1-2, the automated assistance device includes a conveyor line 201, a pick-out robot 202, and a sanding cleaning robot 203. The conveying line 201 is disposed between the upper bin 101 and the lower bin 103 to convey the optical film, the material taking manipulator 202 is disposed near the conveying line 201 and the two grinders 102 to realize feeding and discharging, and the two polishing cleaning manipulators 203 are respectively disposed on the traveling shafts in front of the respective grinders 102 to sequentially polish and clean the respective optical film on each grinding station.
