Description

Technical Field

[0001] The present invention belongs to the technical field of solar cell wafers, and relates to a full-automatic buffer system, in particular to a full-automatic buffer system for solar photovoltaic cells. Background Art

[0002] With the rapid development of the photovoltaic industry and the continuous increase of solar energy and photovoltaic cell product manufacturers, most enterprises have higher and higher requirements for manufacturing cost control. People tend to localize the main equipment for the production of solar photovoltaic cell products, and the research, invention and manufacturing cost of the components of the equipment composition tend to gradually decrease. The simple and flexible operation performance has become the main concern of many battery product manufacturers.

[0003] After retrieval, a battery wafer buffer device and a battery wafer production system are disclosed in a Chinese patent document [Application No.: 202220493556.9; Publication No.: CN 217239414 U]. This battery wafer buffer device includes: a first frame and a second frame, the first frame and the second frame are arranged opposite to each other at intervals, and the first frame and the second frame are respectively arranged on opposite sides of the battery wafer conveying direction; support columns, at least two support columns are respectively arranged at intervals at the same height of the first frame and the second frame. The battery wafers are transferred between various processes along with the conveyor belt, and the battery wafers are temporarily stored on the battery wafer buffer device. Since the support columns are arranged at intervals on the first frame and the second frame, the volume is small, and the battery wafers are in point contact, so foreign matters are not easy to remain, which is beneficial to reducing the probability of foreign matters falling onto the lower battery wafers. The point contact of the support columns with the battery wafers is beneficial to reducing the contact area with the battery wafers and reducing the probability of the battery wafers being contaminated during buffering, thereby improving the yield rate of the battery wafers.

[0004] Although the first frame and the second frame disclosed in this patent are beneficial to reducing the probability of foreign matters falling onto the lower battery wafers, the point contact of the support columns with the battery wafers is beneficial to reducing the contact area with the battery wafers and reducing the probability of the battery wafers being contaminated during buffering, thereby improving the yield rate of the battery wafers. However, it cannot automatically store and take out the battery wafers, and the working efficiency is low. Summary of the Invention
