Cleaning device for sealing machine sealing heads

Abstract

The invention provides a cleaning device for sealing machine sealing heads and belongs to the technical field of battery production equipment. The technical problems that people are prone to be scalded when an existing sealing machine is cleaned manually, and the like are solved. The cleaning device for the sealing machine sealing heads comprises a bracket and a drive mechanism. The bracket is provided with a liquid injection head and a cleaning head, and the cleaning head is wrapped with a wiping layer for absorbing liquid. The liquid injection head injects a solvent for dissolving residual glue on the wiping layer. The drive mechanism enables the cleaning head to stretch between the upper sealing head and the lower sealing head and move along the inner surface of the upper sealing head or the inner surface of the lower sealing head by driving the bracket. By means of the cleaning device for the sealing machine sealing heads, a sealing machine can have self-cleaning capacity, and thecleaning device can clean the upper sealing head and the lower sealing head just by making the sealing machine be subjected to regular machine halt through a control program.

Description

technical field [0001] The invention belongs to the field of battery production equipment and relates to a cleaning device for the sealing head of a packaging machine. Background technique [0002] Polymer lithium batteries are widely used in our lives, such as mobile phones, cameras and so on. The current battery cell assembly method requires the battery pole group to be packaged in an aluminum-plastic case. In the top packaging of the leading edge of the flexible packaging lithium-ion battery, it is mainly packaged with PP glue and packaged by a packaging machine in a heated state. [0003] my country's patent application literature (notification number: CN206116536U; announcement date: 2017.4.19) discloses a capping and diversion head of a polymer lithium battery, including a capping upper head and a capping and diversion lower The head, the upper head of capping and the lower head of capping and diversion are parallel to each other, and a gap is arranged between the upp...

AI Technical Summary

Problems solved by technology

However, in the process of packaging, some overflow glue will remain on the head. In order to avoid the poor seal level caused by the overflow glue remaining on the head, and the poor appearance of the cell edge sealing, it is necessary to stop the machine in time to clean the residual PP glue. Otherwise, the batteries may be scrapped in batches

[0005] The existing method of cleaning PP glue on the head is generally manual cleaning by employees, but since the temperature of the head is generally 170° to 210°, there is a risk of burns when the employees manually clean the residual glue

At the same time, manual cleaning is time-consuming, equipment downtime is long, and production efficiency is difficult to improve
