Description

Technical Field

[0001] The utility model belongs to the technical field of power battery production tooling, and in particular relates to a power battery CCS product pressing tooling. Background Art

[0002] As a key connection system in the power battery module, the power battery CCS (Cell Contact System) product is responsible for electrical connection between battery cells, temperature and voltage sampling, and other functions to ensure efficient and safe operation of the battery module.

[0003] The pressing process of power battery CCS products occupies an important position in power battery processing. At present, in the pressing process of power battery CCS products, the traditional method is to use light film and TPX release film for padding protection pressing, which plays a certain role in isolation and protection during the pressing process, but they do not have special adsorption function for the problem of residual flux. During the pressing process, the flux melts due to heat, and may overflow after being pressed and squeezed by the airbag. Since the light film and TPX release film do not have the ability to adsorb flux, the overflowed flux easily migrates to the nickel sheet area, exceeding the standard requirements for product appearance. In addition, the operator needs to wipe the residual flux twice, which is inefficient, time-consuming, and labor-intensive.

[0004] Through the above analysis, the problems and defects of the existing technology are: the traditional pressing method cannot absorb the residual flux, the overflowed flux easily migrates to the nickel sheet area, and a second wiping is required, which is inefficient, time-consuming and labor-intensive. Utility Model Content

[0005] In order to overcome the problems existing in the related technologies, the utility model provides a pressing tool for a power battery CCS product.

[0006] The technical solution of the utility model is as follows: A power battery CCS product pressing tool is provided with: a supporting plate, a positioning plate, and a cover plate;

[0007] The supporting plate, positioning plate and cover plate are connected by hinges, and the positioning plate is installed between the supporting plate and the cover plate; a kraft paper layer is laid on the upper surface of the supporting plate, and the kraft paper layer is located between the supporting plate and the positioning plate; a positioning groove is opened in the middle of the positioning plate, and a plurality of nickel sheet installation grooves are opened on both sides of the positioning groove.

[0008] In one embodiment, a plurality of positioning protrusions are respectively provided on the edges of both ends of the positioning groove, and the positioning protrusions on both sides are arranged alternately.

[0009] In one embodiment, both ends of the support plate and the cover plate are respectively fixed with mutually matching buckles.

[0010] In one embodiment, an arc-shaped handle is fixed to the rear end of the supporting plate, and a hanging groove is provided on the inner side of the middle of the arc-shaped handle.

[0011] In one embodiment, a placement groove is provided on the upper surface of the support plate, the kraft paper layer is laid in the placement groove, and an arc-shaped notch is provided on the front edge of the placement groove.

[0012] In one embodiment, a lifting plate is fixed to each of the two ends of the front side of the cover plate, and the surface of the lifting plate is provided with anti-slip grooves.

[0013] Combined with the above technical solution, the beneficial effects of the utility model are as follows: the utility model can effectively absorb the flux residue that may be generated during the pressing process by laying a kraft paper layer on the upper surface of the support plate, and the kraft paper layer is located between the support plate and the positioning plate. The kraft paper has a strong adsorption capacity and can effectively prevent the overflowed flux from migrating to the nickel sheet area, thereby avoiding the need for secondary wiping. Due to the reduction in the need for secondary wiping, this pressing tooling greatly reduces the manpower and working hours costs and improves work efficiency. The positioning groove in the middle of the positioning plate and the nickel sheet installation grooves on both sides not only ensure the accurate positioning of the nickel sheet during the pressing process, but also prevent the flux from contaminating the nickel sheet area through the kraft paper layer, which helps to protect the nickel sheet and improve the quality and reliability of the product.

[0014] The utility model provides multiple positioning protrusions on the edges of both ends of the positioning groove, and the positioning protrusions on both sides are arranged in a staggered manner, which can ensure that the CCS product is accurately positioned during the pressing process, reduce position deviation, and improve the pressing accuracy. The staggered positioning protrusion design can increase the stability of the CCS product in the tooling and prevent sliding or tilting during the pressing process.

[0015] The utility model can ensure a close fit between the supporting plate and the cover plate by respectively fixing mutually matching buckles at both ends of the supporting plate and the cover plate, so as to facilitate storage.

[0016] The utility model facilitates operators to hold and move the tooling through the arc-shaped handle fixed at the rear end of the support plate, thereby improving the convenience of operation. The hanging groove in the middle of the arc-shaped handle can conveniently hang the tooling on a wall or other fixed objects, saving space and facilitating storage.

[0017] The utility model can improve the laying stability of the kraft paper layer by means of the placement groove provided on the upper surface of the supporting plate, and the arc-shaped notch provided on the front edge of the placement groove can facilitate the operation of the kraft paper layer in the placement groove.

[0018] The utility model facilitates operators to lift the cover plate through the lifting plates fixed at both ends of the front side of the cover plate, which is labor-saving and easy to operate. The anti-skid patterns on the surface of the lifting plate can increase the friction when holding and prevent slipping during operation.
