Ribbon fine-tuning device, ribbon fine-tuning method, and stringer

Abstract

The invention discloses a welding strip fine adjustment device. The welding strip fine adjustment device comprises a connection part, a screwing mechanism and an adjustment mechanism, wherein the screwing mechanism and the adjustment mechanism are fixedly connected to the connection part; an eccentric part is arranged at the lower end of the screwing mechanism; a groove through which a welding strip passes is formed in the bottom of the adjustment mechanism; a moving part is arranged at one end, through which the welding strip enters the groove, of the adjustment mechanism; the moving part comprises a left moving block and a right moving block; the left moving block and the right moving block are respectively arranged on the left side and the right side of the eccentric part; the rotation of the eccentric part drives the left moving block to move left or drives the right moving block to move right, so that the adjustment mechanism moves left or right. According to the welding strip fine adjustment device of the embodiment, the welding strip finds an optimum position aligned to a grid line of a battery piece in the process of moving left and right through mutual cooperation between the eccentric part and the left moving block as well as the right moving block, so that the blank leakage is overcome; the purposes of enabling the component to be attractive and improving the efficiency of the component can be achieved.

Description

technical field [0001] The invention relates to the technical field of solar photovoltaic module production, in particular to a ribbon fine-tuning device, a ribbon fine-tuning method, and a stringer. Background technique [0002] In the production process of crystalline silicon solar photovoltaic cell modules, the first process is the cell string welding process. During string welding, the front of the cell is welded and connected to the back of the adjacent cell to form a cell string. The final battery strings will also enter the lamination process after undergoing such processes as typesetting, busbar welding, and insulating film laying. [0003] At present, there are various specifications of photovoltaic cells in the photovoltaic market, so most of the cells and ribbons will have more or less bias between the ribbon and the grid line after welding, also known as the phenomenon of "white leakage" of the cells. The phenomenon not only affects the appearance of the battery...

Problems solved by technology

[0003] At present, there are various specifications of photovoltaic cells in the photovoltaic market, so most of the cells and ribbons will have more or less bias between the ribbon and the grid line after welding, also known as the phenomenon of "white leakage" of the cells. The phenomenon not only affects the appearance of the battery components, but also affects the quality of the battery components. Therefore, in order to produce beautiful and high-quality battery components, it is necessary to align the soldering strips to the main grid lines of the cells.

The current mainstream automatic stringer generally does not have a fine-tuning function to control the "white leakage" phenomenon of cells, or has an adjustment function but can only be adjusted roughly, which cannot completely overcome this "white leakage" phenomenon.
