Automatic cell material overturning device and method and solar cell production line

Abstract

The invention relates to an automatic cell material overturning device and method and a solar cell production line, and belongs to the technical field of solar cells. The automatic cell material overturning device comprises a frame assembly, a cell material pickup mechanism, a cell material overturning mechanism and a control mechanism, the cell material pickup mechanism picks up a cell material, conveys the picked up cell material to a predetermined position, and comprises at least one non-contact type sucker for picking up the cell material in a non-contact manner; the cell material overturning mechanism overturns the cell material conveyed to the predetermined position by the cell material pickup mechanism for 180 degree; and the control mechanism is in signal connection with the cell material pickup mechanism and the cell material overturning mechanism to control motions of the cell material pickup mechanism and the cell material overturning mechanism, so that the cell material can be turned over automatically. The an automatic cell material overturning device can reduce contact with the cell material, reduces the probability of cell material pollution, and has less influence on the photoelectric conversion efficiency of solar cells.

Description

technical field [0001] The invention relates to the technical field of solar cells, in particular to an automatic sheet turning device and method for sheet materials and a solar cell production line. Background technique [0002] With the rapid development of science and technology, people's awareness of energy conservation and environmental protection is also constantly improving. It has become an upsurge to replace non-renewable energy with green energy. Solar energy, as an inexhaustible and inexhaustible renewable energy, has gained unprecedented The rapid development of solar cells, and the research and development of solar cells have been paid more and more attention. [0003] Silicon heterojunction solar cells are just one type of solar cells, and the existing silicon heterojunction solar cell preparation processes include cleaning texturing, PECVD (Plasma Enhanced Chemical Vapor Deposition, plasma enhanced chemical vapor deposition) coating, Steps such as PVD (Physic...

Problems solved by technology

[0004] However, the existing turning device for sheets needs to pick up the sheet during the turning process, and during the picking process, the turning device will contact the surface of the sheet, causing impurities on the turning device to stick to the surface of the sheet , thereby contaminating the sheet and reducing the photoelectric conversion efficiency of the solar cell
