Description

Technical Field

[0001] The utility model relates to the technical field of battery cell series connection machine accessories, and in particular to a scraper mechanism and a battery cell series connection machine. Background Art

[0002] The battery cell series connection machine is a device that uses glue to string solder the welding ribbon on the battery cell. The scraper mechanism is an important structure in the battery cell gluing device. Its function is to squeeze the glue inside the mesh plate so that the glue adheres to the position on the battery cell where glue is required. The scraper mechanism in the prior art generally includes two scraper assemblies. The action flow of the two scraper assemblies is: the left scraper lifting motor controls the left scraper assembly, and the right scraper lifting motor controls the right scraper assembly. When the left scraper assembly scrapes glue on the mesh plate to the right, the right scraper lifting motor drives the right scraper assembly to lift; conversely, when the right scraper assembly scrapes glue on the mesh plate to the left, the left scraper lifting motor drives the left scraper mechanism to lift. The scraper mechanism using this structure requires two sets of lifting motors to respectively control the longitudinal movement of the left and right scraper assemblies, thereby making the structure of the scraper mechanism complex and the cost high, and making it more difficult to repair and maintain. Therefore, a scraper mechanism and a battery cell series connection machine are provided to solve the above problems. Utility Model Content
