A kind of aluminum-plastic film stamping equipment for soft-pack lithium battery and its stamping process

Abstract

The invention relates to an aluminum-plastic film stamping equipment for a soft-packed lithium battery and its stamping process, including a support base plate, a transmission device, a cutting device and a stamping device. A transmission device is installed on the top of the left end of the support base plate, and the cutting device is installed On the middle part of the support base plate, the stamping device is connected with the right end top of the support base plate; the transmission device includes a transmission roll, a transmission rotating shaft, a rotating shaft support plate, a shifting plate, a buffer connecting frame, a rotating plate, a blocking frame and a buffer spring. The present invention can solve the problem that the aluminum-plastic film existing in the outer packaging of the soft-packed lithium battery cannot be automatically conveyed when it is punched, the wrinkle phenomenon occurs when the aluminum-plastic film is conveyed, the stamping die cannot be adjusted for stamping size, and the aluminum-plastic film cannot be automatically conveyed. The position around the aluminum-plastic film will be deformed during stamping, the aluminum-plastic film cannot be automatically cut, and the cutting effect of the aluminum-plastic film is poor.

Description

technical field [0001] The invention relates to the technical field of lithium battery production, in particular to an aluminum-plastic film stamping equipment for a soft-pack lithium battery and a stamping process thereof. Background technique [0002] Soft-pack lithium battery is a kind of lithium battery. Soft-pack lithium battery is just a liquid lithium-ion battery covered with a polymer shell. When the air blows and cracks, the aluminum-plastic film needs to be stamped and formed first in the processing of the soft-packed lithium battery, so that the battery core can be placed in the stamping space. Existing small and medium-sized battery manufacturers generally use aluminum-plastic film when stamping It is carried out in a semi-automatic way. The problems of this working method are as follows. The aluminum-plastic film cannot be automatically conveyed, resulting in low stamping efficiency of the aluminum-plastic film. Wrinkles will occur when the aluminum-plastic film...

AI Technical Summary

Problems solved by technology

[0003] In order to solve the above problems, the present invention provides a soft-packed lithium battery aluminum-plastic film stamping equipment and its stamping processing technology, which can solve the problem that the existing aluminum-plastic film of the soft-packed lithium battery cannot be stamped automatically. Wrinkles will occur during transmission and aluminum-plastic film transmission, the stamping die cannot be adjusted for stamping size, the position around the aluminum-plastic film will be deformed when the aluminum-plastic film is stamped, the aluminum-plastic film cannot be automatically cut, the cutting effect Poor problems; it can realize the function of stamping the aluminum-plastic film into the required size and cutting the stamped aluminum-plastic film at a suitable position, with automatic transmission of the aluminum-plastic film and no wrinkles during transmission Phenomenon, the stamping mold can adjust the stamping size, the position around the aluminum-plastic film will not be deformed when the aluminum-plastic film is stamped, the aluminum-plastic film can be automatically cut, and the cutting effect of the aluminum-plastic film is good, etc.
