[0002] The solar cell product is a small cell. In the field of solar cell production, the welding ribbon is mainly welded to the solar cell, so that each cell can exist independently and be connected in series. This small The battery sheet is relatively thin, and the common thickness is between 0.2mm-0.25mm. There are many specifications of the battery sheet in life, but they are all thinner, and the toughness of the battery sheet is not strong. Because the material is relatively brittle and easy to be damaged, solar energy In the existing production process, the work of battery strip welding is only done by hand. The traditional manual work method is inefficient and the process is relatively complicated. Due to the constraints and limitations of human factors, the quality of the produced batteries is poor. Problems such as desoldering, virtual soldering, and welding deviation will consume a lot of manpower and material resources, and the final operation results will also cause problems such as low product qualification rate and low production capacity, which not only affect the production schedule, but also directly cause problems. More serious resource consumption, so the use of modern industrial equipment to complete solar cell strip welding is the development trend required for industrial production and progress

[0003] In order to successfully weld ribbons for a large number of small solar cells that are easily damaged, if industrial equipment is used to complete the ribbon welding operation, the material transfer of solar cells, the material transfer of ribbons, and their welding operations are important to work independently and complement each other. step, and the equipment involved in the process usually has a feeding device for the battery sheet material and a feeding device for the ribbon material. However, it is difficult to complete the work quickly, conveniently and accurately based on the existing production technology. For example, the feeding and receiving device fails to meet the characteristics of solar cells and fast supply or mobile phone Requirements, as another example, the feeding device of the welding ribbon is manually operated, that is, using human control to complete the manual cutting of the welding ribbon from the entire plate of welding ribbon, and then soak it in a container containing flux, and remove it after soaking Get up and dry the flux attached to the ribbon, then place the cell on a preheated soldering table for preheating positioning, then take out a dried solder ribbon with tweezers, and align it with the middle of the cell. Silver coating, followed by fusion welding with ferrochrome from front to back, it is also necessary to ensure that one end of the ribbon is within 1-2mm from the edge of the battery sheet, and at the same time ensure that the ribbon is welded on the battery sheet without any detachment Welding, virtual welding, welding deviation and other problems occur, so the steps are not only extremely cumbersome, but also consume a lot of physical strength of the operator, and the fatigue degree is aggravated
