Intermittent coating electrode lug gluing device and gluing rack thereof

Abstract

The invention discloses an intermittent coating pole lug gumming device and a gumming machine frame thereof. A spray head bracket and a water tank bracket are arranged on a main frame body of the gumming machine frame. The spray head bracket is assembled on the main frame body in guiding and moving mode along the vertical direction. A spray head low position used to enable a nozzle of a gumming spray head to fall into a water tank or offset on one horizontal side of the water tank and a spray head high position used to locate the nozzle of the gumming spray head above the water tank are arranged within the move stroke of the spray head bracket. Accordingly, glue liquid sizing gummed on the inner side and the outer side of the nozzle of the gumming spray head is immersed in liquid in the water tank so as to prevent the circumstance that the remaining glue liquid sizing on the inner side and the outer side of the nozzle of the gumming spray head coagulates, and further prevents the remaining glue liquid sizing from blocking the gumming nozzle, the remaining glue liquid sizing in the gumming spray head is prevented from coagulating in coating intervals, and then can not stop a next gumming job, and therefore efficiency and quality of coating operation are improved.

Description

technical field [0001] The invention relates to an intermittent coating lug gluing device and a gluing frame thereof. Background technique [0002] At this stage, in order to improve the safety, capacity, consistency and other performance of the battery in the production process of lithium-ion batteries, intermittent coating technology has been gradually adopted for the tab insulation treatment of lithium-ion batteries to replace the traditional adhesive tape or continuous coating. The way of cloth, and the stopping performance of glue nozzle in intermittent coating technology will become a key factor affecting the quality of intermittent coating. Chinese patent document 201010124443.3 discloses a method for intermittent coating of extrusion coating machines, including slurry sealed tanks, precision screw pumps, servo motors, feeding pipelines, return pipelines, drainage pipelines, pneumatic or servo motors Intermittent control valve, extrusion head, servo motor drives the ...

AI Technical Summary

Problems solved by technology

[0003] 1. Although the pneumatic or servo motor will no longer supply material to the extrusion head after the intermittent control valve of the pneumatic or servo motor is turned off, the slurry in the cavity of the extrusion head will not completely flow back to the slurry through the drainage pipeline. In the material sealed tank, especially the residual slurry at the extrusion port of the extrusion head, and this part of the slurry will condense rapidly without stirring in the extrusion head, resulting in the problem that the extrusion port of the extrusion head is blocked , so that the slurry discharge will not be smooth in the next coating operation, which will affect the accuracy of the coating operation

[0004] 2. At the end of a coating operation, some glue slurry will stick to the outside of the extrusion port of the extrusion head. After this part of the glue slurry is condensed outside the extrusion head, it will not only affect the normal discharge Cause blockage, and these coagulated rubber blocks, colloidal particles and other solids are easily bonded to the workpiece along with the re-discharged glue slurry, so that the product quality cannot be guaranteed after the coating operation
