Three-in-one lithium battery cap assembly device

Abstract

The invention relates to a three-in-one lithium battery cap assembly device. The three-in-one lithium battery cap assembly device comprises a base, wherein a rotary disc is arranged on the base and driven by a stepping motor, a circle of internally-sunken round stations which are uniformly arranged are arranged on the rotary disc, and an anti-explosion sheet feeding station, a gasket feeding station, an upper cover feeding station, a press sealing station and a discharge station are sequentially arranged along the external circumference of the rotary disc; the gasket feeding station adopts multiple clips to sequentially feed; when a gasket in a clip is finished, a support rod retracts, a rotary air cylinder rotates, another clip fully loaded with gaskets is transferred to the part above the support rod for continuously feeding, the feeding time is saved, and the production continuity is maintained; and anti-explosion sheet is in press fit with an upper cover, and one-time forming is prevented to cause deformation of the anti-explosion sheet. According to the technical scheme, lamination is gradually carried out by three times, and the lamination effect is good; a hole expansion station is additionally arranged behind the anti-explosion sheet station, the mouth of the anti-explosion sheet is expanded, the gasket and the upper cover are conveniently loaded into the anti-explosion sheet in subsequent stations, the efficiency and the yield are effectively improved, and the loss is reduced.

Description

technical field [0001] The invention relates to the field of lithium battery cap production, in particular to a three-in-one lithium battery cap assembly equipment. Background technique [0002] Lithium batteries are used in battery packs of battery cars, electric gun drills and other power tools. One of the important safety accessories for lithium-ion power batteries is the cap. At present, the combination cap factory mainly adopts the subsection manual operation method to process the combination cap. The method is: first put the upper cover into the station manually, then manually expand the upper cover, put in the gasket and the explosion-proof membrane at one time, and finally seal the explosion-proof membrane for many times; then Use a punching machine to flatten the finished product and transfer it to the next process for assembly; there are many defects in the assembly process, such as many processes, many labors, and low production efficiency, and in the stamping p...
