Description

Technical Field

[0001] The utility model relates to the technical field of battery production equipment, in particular to a detecting mechanism for a battery laminated plate electrode group. Background Art

[0002] Laminating is an important process in the battery production process. In the existing battery production laminating process, multiple electrode plates are stacked and assembled on a laminator to form an electrode group, and then conveyed to the rear for manual shaping or shaping by equipment. Since the electrode plates are not individually weight-detected before forming the electrode group by laminating, there is a weight error between the electrode plates. Therefore, it is necessary to weigh the electrode group after shaping. At present, the weighing process for the electrode group is mostly manual weighing, with a large labor intensity and low detection efficiency. Moreover, there are large errors in manual operation, which cannot ensure the consistency of the batteries, thus affecting the service life of the batteries. There are also weighing devices set on the laminator, which will give an alarm prompt to manually remove when the weighing is unqualified. There are still problems of large labor intensity and low detection efficiency. Summary of the Invention
