Battery end face tab pressing machine

Abstract

The invention relates to a battery end face tab pressing machine. The machine is used for hot-pressing and fixing a steel sheet and a battery shell. The machine comprises a machine table, a translation workbench for supporting a steel sheet and the battery shell, and an equal-height distance-limiting heat sealing mechanism for pressing a material product; the equal-height distance-limiting heat sealing mechanism comprises a lower heating pipe fixedly connected with the machine table, a sliding rail assembly and an upper heating pipe movably connected with the machine table through the slidingrail assembly, and the moving direction of the upper heating pipe is perpendicular to the plane where the translation workbench is located. According to the battery end surface tab pressing machine provided by the invention, the steel sheet and the battery shell are subjected to hot-pressing fixation by utilizing the heating pipe with the annular end face, and the high-temperature heating pipe isisolated through a heat insulation column, so that the heating pipe is prevented from damaging surrounding parts, and the stability of the pressing machine equipment is ensured.

Description

technical field [0001] The invention relates to the field of battery production, in particular to a tab pressing machine for battery end faces. Background technique [0002] With the increasing popularity of electronic products, people's demand for batteries is also increasing. With the development of battery technology, people began to develop batteries different from the traditional structure. For example, the patent document with the publication number CN111029487A discloses a high energy density battery, which uses steel sheets on both ends to replace the traditional tab connections exposed outside the battery. Specifically, the upper and lower end faces of the battery have circular hollow areas, and the steel sheet is partially exposed in the hollow areas. As a newly developed battery with a new structure, there is currently no production equipment for this battery structure on the market, especially for the pressing operation of the battery case and the steel sheet. ...
