[0002] With the booming development of the photovoltaic industry, the production line of solar cell modules is becoming more and more intelligent and unmanned. However, some processes still require manual operation to complete, including the packaging of finished battery modules. The packing of battery modules consists of many blocks stacked on a pallet, and then buckled into a carton with a cover on the top and no cover on the bottom. Since the size of the cartons used is relatively large, the length, width and height are generally about 2.8 meters, 1.8 meters and 2 meters, and the cartons are initially stacked together, it is difficult to achieve automated operation. In addition, the time interval between the battery modules on the assembly line and the packaging line is not fixed, which makes the automation of this process more difficult.
