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. The automatic sheet turning device includes a frame assembly, a sheet picking mechanism, a sheet turning mechanism and a control mechanism; the sheet picking mechanism is used to pick up the sheet and transport the picked sheet to a predetermined position, The material picking mechanism includes at least one non-contact suction cup for non-contact picking up the sheet; the sheet turning mechanism is used to turn the sheet transported by the sheet picking mechanism to the predetermined position by 180°; The control mechanism is signal-connected with the sheet picking mechanism and the sheet turning mechanism, and is used to control the action of the sheet picking mechanism and the sheet turning mechanism, so that the sheet can be turned over automatically. The automatic sheet turning device can reduce the contact with the sheet, thereby reducing the probability of polluting the sheet, and has little influence on the photoelectric conversion efficiency of the solar cell.
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...
