Novel pressing claw device

Abstract

The invention discloses a novel pressing claw device. The novel pressing claw device comprises a pressing plate, a drive part driving the pressing plate, a plurality of pressing claws located under the pressing plate, a foundation base for bearing the parts and an installation base connected to the foundation base; installation parts for installing the pressing claws are arranged on the installation base at intervals, and an installation gap is formed between every two adjacent installation parts; convex installation plates are arranged on the tails of the reverse sides of the installation parts at intervals and are located on the joints between the installation parts and the installation gaps, and a concave installation plate is formed between every two adjacent convex installation plates; clamping and connecting elements are arranged at the tails of the pressing claws and are clamped from the installation gaps; one installation gap is connected to one or two pressing claws in a clamping mode, and the clamping and connecting ends of the clamping and connecting elements are placed on the convex installation plates or the concave installation plates; the pressing claws are connected to the installation parts in a rotating mode. According to the novel pressing claw device, the pressure welding position is more accurate, the pressing strength is more appropriate, the compatibility is high, the requirements of pressure welding of battery pieces of various specifications can be met, and the product quality can be improved.

Description

technical field [0001] The present invention relates to a new type of pressing claw device, in particular to a new type of pressing claw device used to make the welding strip and the grid line in the battery sheet contact when the battery sheet is welded. Background technique [0002] With the widespread application of solar energy, the solar photovoltaic panel industry is also booming. As an important component of the solar photovoltaic panel, the battery panel needs to be welded together with the grid wire of the battery sheet during the production process. The traditional welding method is: laying the welding ribbon on the battery sheet and directly welding. However, during welding, due to the lightness of the welding ribbon, it is impossible to ensure the complete contact between the welding ribbon and the battery sheet, so it will cause a virtual soldering phenomenon. [0003] In view of the above defects, the industry currently uses a welding platen device to assist ...

AI Technical Summary

Problems solved by technology

Using the above device, although the situation of virtual welding can be improved, but because the grid line specifications of the cells are different, such as three-grid cells, four-grid cells or five-grid cells, etc., plus the structure of the welding press plate device Due to the above defects, the device can only assist in the welding of cells of the same specification, so it cannot perform auxiliary welding of cells of multiple specifications, and cannot adapt to the production of products of multiple specifications
