Its main technology is reflected in the overall structure design, welding and processing process control, etc. Now it is aimed at the cell module and For laser welding between integrated circuit covers, it is first necessary to match and fix the integrated circuit cover on the surface of the corresponding battery pole. At present, due to many unavoidable reasons such as the purity of the cover material and the welding temperature, explosion The point will cause damage to the welded body and reduce the welding quality. In addition, the integrated circuit cover plates for different battery modules need to be equipped with corresponding fixed protection devices, which will increase the frequency of fixed replacement between integrated circuit cover plates and reduce production efficiency.

Utility model content

The utility model provides a combined device which can be applied to different battery modules and can be fixed and protected during the welding process of the battery modules, so as to reduce the fixed replacement between different battery modules and integrated circuit cover plates. Frequency, protect the cell module explosion-proof valve, wiring harness, etc. from damage caused by welding spatter.

In order to solve the above technical problems, the utility model adopts the following technical solutions:

A pull-out protection combination device used for welding when cell modules are formed, the device includes a protection combination cover plate and two clamping devices symmetrically arranged at both ends of the protection combination cover plate, the protection combination cover plate includes a protection The main cover plate and two protective auxiliary cover plates are symmetrically connected to the main protective cover plate in a sliding manner. The two ends of the clamping device are downwardly provided with positioning pins fixed with the cell module.

Preferably, the sliding connection between the main protection cover and the auxiliary protection cover is realized through a chute installed on the inside of the main cover and a moving guide rail on the outside of the auxiliary protection, so that the auxiliary protection cover is relatively The cover plate can slide left and right.

Preferably, stop plates are provided at both ends of the main protection cover, and anti-off plates corresponding to the stop plates are arranged at the ends of the auxiliary protection cover. It can prevent the auxiliary cover from falling off.

Preferably, the clamping device is two symmetrical convex structures, the protruding ends of which are opposite to each other, and the positioning pins are arranged at the positions of the two protruding ends of the protruding structures.

Further, the handle end of the convex structure is connected to the two protective auxiliary covers by a hinge, so that the clamping device can move.

It can be known from the above technical solutions that the utility model provides a pull-type protective combination cover plate and a convex clamping movable device to fix and protect the integrated circuit cover plates of different types of modules, reducing the need for different modules to be fixed. Replacement frequency and improve the quality of laser welding.

detailed description

A preferred embodiment of the present utility model will be described in detail below in conjunction with the accompanying drawings.

As shown in Figure 1, in this embodiment, the combination device includes a protective combination cover 1, a hinge 2, a convex clamping device 3, etc., and the protection combination cover 1 is composed of a main protection cover 5 and two A symmetrical protective auxiliary cover 6 slidingly connected to the protective main cover 5 is used to cover the protected integrated circuit cover and battery module to protect the explosion-proof valve of the battery module and the integrated circuit cover. Board wiring harness, etc., its main and auxiliary combined structure can be pulled out while realizing the protection and fixing of different battery modules, and the versatility is enhanced.

In this embodiment, the device is preferably provided with a linear sliding guide rail 7 on the protective auxiliary cover plate, and at the same time, a linear chute 9 cooperating with the sliding guide rail is set on the protective main cover plate 5, and the protective auxiliary cover plate 6 is realized through the above structure. Move left and right relative to the protective main cover plate 5, so that the combined device can be pulled to a corresponding size according to the number of battery core modules.

In this embodiment, as shown in Figure 1, in order to prevent the falling off between the protective main cover 5 and the protective auxiliary cover 6, stop plates 8 are provided at the ends of both sides of the protective main cover 5, and at the same time, the protective auxiliary An anti-off plate 9 is arranged on the end of the cover plate 6 .

In this embodiment, the clamping device 3 is preferably designed as two symmetrical convex structures, and the end of the protective auxiliary cover plate 6 is connected with the handle end of the convex structure through the hinge 2, ensuring that the clamping device 3 It can move freely to deal with the errors that occur when the cell module end plate is installed. The positioning pin 4 is arranged on the protruding end of the convex structure, facing downward, and the end plates on both sides of the battery module are provided with hole slots. The connection of the hinge 2 can ensure that the positioning pin 4 is inserted into the hole slot, and the positioning pin 4 makes the battery The core module, the integrated circuit cover plate and the pull-out combination are fixed together.

In the specific operation, when the cell module undergoes laser welding process, the operator places the cell module on the module tray, and covers the corresponding integrated circuit cover of the cell module on the electrode of the cell module. On the surface of the column, pull the size of the pulling protection combination device to the same place as the thickness of the cell module, and adjust the orientation of the clamping device 3 through the action of the hinge 2, so that its positioning pin 4 can be smoothly inserted into the cell The laser welding operation is carried out after the holes and grooves of the end plates at both ends of the module. When the operator performs other laser welding tasks of different numbers of cell modules, the installation size of the pulling protection device is sequentially adjusted to match it before performing the welding task, so it has good versatility.
