Description

technical field [0001] The invention relates to the field of power module production equipment, in particular to a glue filling device for power module manufacturing. Background technique [0002] The colloidal lead-acid battery is an improvement to the common lead-acid battery with liquid electrolyte. The sulfuric acid electrolyte is replaced by the colloidal electrolyte. The battery uses a gel-like electrolyte, and there is no free liquid inside. The electrolyte capacity is large and the heat capacity is large under the same volume. , strong heat dissipation ability, can avoid thermal runaway phenomenon that is easy to occur in general batteries; low electrolyte concentration, weak corrosion effect on plates; uniform concentration, no electrolyte stratification. The performance of colloidal lead-acid batteries is better than that of valve-regulated sealed lead-acid batteries. Colloidal lead-acid batteries have stable performance, high reliability, long service life, strong...

AI Technical Summary

Problems solved by technology

[0003] In order to improve battery performance, the general battery production is no longer using sulfuric acid alone, but instead injecting silica, sulfuric acid and other colloids. This colloid is generally more viscous and easy to solidify. The existing general glue filling mechanism The quantitative system is not accurate enough. When the glue is poured, if the amount of glue cannot be returned in time, it will block the glue outlet and cause cumulative errors, which will affect the working efficiency of the overall device.
