Photovoltaic rolled glass sheet unloading method

Abstract

The invention discloses a photovoltaic rolled glass sheet unloading method. A glass frame stack position calculation method is utilized. When glass sheets are placed on a suction cup frame, the distance between the horizontal position and the stack position is accurate and fixed, meanwhile, the height of the placed glass sheets and the height of a glass stack bottom support are controlled, the lower portions of the stacked glass sheets can be tightly attached to the glass stack, no gap exists between the glass sheets, and the problem that the thickness difference of the upper portion and the lower portion of the glass stack is too large is solved. After a certain number of pieces of glass are stacked, the deviation is controlled within a reasonable range by tracking and calculating the automatic retreating accumulated distance and performing turnover angle supplement on the parallel difference between the outer edge surface of the stack position and the plane of the glass sheets to be stacked after turnover, so that parallel attachment is ensured, the phenomenon of scratching among the glass sheets is avoided, and the quality of the glass stack is greatly improved. No extra time is added in the whole batch-off period. Position pairing of a glass frame and a suction cup frame is not needed during first sheet stacking, the first sheet stacking time is not increased, operation is completely automatic, and the high-speed sheet unloading requirement of a production line is better met.

Description

Technical field [0001] The present invention belongs to the field of photovoltaic calendering glass production, and in particular, the present invention relates to a photovoltaic pressure gauze. Background technique [0002] The photovoltaic cave glass plasma production line is laminated, and the lower case of vertical stack is adapted to the production characteristics of a multi-line photovoltaic cave glass. The original film thickness is thin, the specifications are small, and the stacking area is small, but The stacking quality is high, the stack is generated to grow the shape shape, the upper and lower thickness is small, and there is no gap between the tablets without hacking, to meet the subsequent packaging and transportation needs. [0003] At present, the next film in this area is basically as follows: The glass sheet entering the stacking area completes the positive operation before the conveyor belt, and positions the position to confirm at the end of the conveyor belt...

AI Technical Summary

Problems solved by technology

This unloading method conforms to the control logic of the conventional stacking process, but the thickness difference between the upper and lower sides of the actual glass stack is relatively large, and it is easy to have scratches or gaps on the lower side between the glass stacks, and subsequent packaging of irregular cuboid stacks is difficult. Vulnerable to vibration and damage during transportation
