New claw device

Abstract

The invention discloses a novel pressing claw device, which includes a pressing plate, a driving part for driving the pressing plate, several pressing jaws located under the pressing plate, and a base for carrying various parts. There are installation parts for installing the pressure claws at intervals between the seats, and installation gaps are formed between adjacent installation parts; installation bosses are arranged at intervals at the rear of the opposite side of the installation parts, which are located at the junction of the installation part and the installation gap, and the adjacent installation bosses A mounting concave platform is formed between them; the tail of the pressing claw is provided with a snap-in element, and the snap-in element snaps in from the installation gap; one or two pressure claws are snapped into the installation gap, and the snap-in end of the snap-in element is placed on the installation protrusion On the platform or on the installation concave platform; the pressure claw is rotatably connected to the installation part; the new pressure claw device provided by the present invention has a more accurate crimping position, a more suitable pressing force, and has high compatibility, adapting to multiple specifications of batteries Chip crimping work, improve product quality.

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
