Description

TECHNICAL FIELD

[0001] The utility model mainly relates to the technical field of vehicle-mounted glass cover plate processing, and particularly relates to a CNC machine platform processing automatic positioning and cleaning device. BACKGROUND

[0002] In the modern automobile industry, vehicle-mounted electronic devices are increasingly widely used, among which vehicle-mounted display systems play a key role. As an important component for protecting and optimizing display effects, vehicle-mounted glass cover plates face many challenges and demands in technical development.

[0003] Manual positioning and placing processing using a corner will result in inaccurate placing positions, causing the grinding head to not grind part of the cover plate glass edge, thereby causing bright edge defects. Or, the ground part of the glass edge exceeds the grinding head movement track, causing abnormal wear of the grinding head sand wheel and resulting in grinding edge defects. Large placing deviations will directly cause the machine table to collide with the knife, and manual cleaning of the jig will result in small particles between the cover plate glass and the jig, causing scratches when the cover plate glass and the particles rub against each other during placing alignment. In summary, the current processing mode greatly affects the production yield of cover plate glass and has a great impact on production safety. UTILITY MODEL CONTENTS
