Description

Technical Field

[0001] The utility model relates to the technical field of battery string production equipment, and in particular to a production equipment for welding and gluing battery sheets into strings. Background Art

[0002] There are two main cell stringing technologies in the prior art: the first is to apply glue on the cell to bond the soldering ribbon and the cell into a string; the second is to heat the soldering ribbon and the cell through infrared lamps to form an alloy to connect them into a string.

[0003] In the existing battery strings formed by alloy connection through infrared lamp heating, the main grid lines on the front and back sides of the battery cells will be thickened, and pad points of a certain size and number will be printed on the main grid lines so that the welding strips and the battery cells can have a good alloy connection. However, this will result in a large amount of silver paste on the main grid lines on the front and back sides of the battery cells, and the wire diameter of the welding strips will also be larger, making the production cost of the battery string relatively high. If the silver paste on the main grid lines on the front and back sides of the battery cells and the wire diameter of the welding strips are reduced in order to reduce the material cost, the strength of the alloy connection between the welding strips and the battery cells will be weak. Therefore, a production equipment for welding and gluing battery cells into strings is provided to solve the problem of low strength of the welding strip connection after the existing battery cells are infrared welded into strings.

[0050] The technical features of the above-described embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0051] The above-mentioned embodiments only express several implementation methods of the utility model, and the description is relatively specific and detailed, but it cannot be understood as limiting the scope of the utility model patent. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the utility model, which all belong to the protection scope of the utility model. Therefore, the protection scope of the utility model patent shall be based on the attached claims.
