Production process method for printing imbricated cell string

Abstract

The invention provides a production process method for printing an imbricated cell string, which not only can effectively ensure the product performance, improve the production efficiency and the product quality and reduce the production and use waste of cells, but also is flexible to operate and high in universality. The method comprises the steps: dividing a whole battery piece into a pluralityof small battery pieces; performing the positioning, arranging, printing, stacking and imbricating of the small battery pieces to complete the welding and stringing after production, thereby achievingthe production of the printed laminated cell string. The tile stacking production is completed through small battery pieces, so the production efficiency can be greatly improved, the utilization efficiency of the battery piece is improved, the production and use waste is avoided, the shutdown maintenance time of equipment is shortened, and the product performance, the product appearance can be ensured and the working efficiency and the productivity are greatly improved. Moreover, the tile stacking production process can be realized no matter whether continuous production is carried out or not, the production operation is more flexible, and the universality is stronger.

Description

technical field [0001] The invention relates to the technical field of shingled components, in particular to a production process for printing shingled battery strings. Background technique [0002] With the advancement of photovoltaic technology and the in-depth advancement of the "Top Runner" program, China's photovoltaic industry has entered an era of high-efficiency product competition. [0003] As one of the mainstream high-efficiency module technologies, the shingling technology is currently receiving widespread attention. The shingling module mainly uses the slicing technology to cut the grid-line redesigned cells into small pieces with reasonable graphics, stack and arrange each small piece, and weld them into strings. , and then laminated into modules after series-parallel typesetting, so that the cells are connected to each other in a more compact way. Under the same area, the shingled module can place more than 13% of the cells of the conventional module, which is...

Problems solved by technology

[0004] However, in the existing production process of welding strings of shingled modules, the material is usually loaded first, and the entire battery sheet is laser cut, and then the entire battery sheet is transported to the printing process for printing, and then the sheets are broken after printing. , shingling and other processes, but in this production process, there will be dust on the cells that are cut first. If not treated, it will affect the subsequent production process and product performance, which will inevitably reduce production efficiency. Affect product quality and product appearance, and even cause waste in the production and use of cells, reducing the utilization efficiency of cells; and because the production process is for the whole cell printing, only continuous production can be carried out, otherwise, shingling and arranging cells cannot be realized process, with operational limitations
