Description

Technical Field

[0001] The utility model belongs to the field of battery preparation, and specifically relates to a heating film positioning device, a rolling device and a battery module heating film installation device. Background Art

[0002] Lithium batteries have the characteristic of working in a relatively suitable temperature environment to exert their maximum energy. In order to ensure that the battery can quickly reach the appropriate temperature, a heating device needs to be attached to the outside of the battery module during the production of lithium battery modules. The commonly used device is the heating film. The heating film is thin and long, which is easy to cause positioning deviation during installation.

[0003] At present, the heating film is installed manually. The heating film includes two symmetrically arranged heating plates and a connecting harness connecting the heating plates. During installation, the personnel first remove the release paper at the bottom of the heating plate, and then two people straighten the heating plate, and then align the positioning through hole at one end of the heating plate with the heating film positioning hole of the battery module. Then the employee on the other side aligns the positioning through hole at the other end of the heating plate with the heating film positioning hole at the other end of the module, and then uses the palm of the hand to press the middle heating film repeatedly several times and stick it to the surface of the module. Complete the installation of the heating film on one side of the module, and then install the heating film on the other side of the module in the same way as above. It takes more than 2 minutes to complete the installation of a heating film, which reduces production efficiency and affects the production rhythm of the entire line. Utility Model Content
