The invention relates to a blocking-prevention glue
injection device of a battery. The block-prevention glue
injection device comprises a bearing table, a plurality of glue injection assemblies, a material tank and a supplied material
assembly, wherein the plurality of glue injection assemblies are arranged in parallel at equal intervals, the material tank is used for storing
colloid, a plurality of battery steel shells are carried in the supplied material
assembly, the glue injection assemblies are in vertical correspondence to glue injection openings of the battery steel shells, each glue injection
assembly comprises a power element, a press plate, a
discharge rod, a glue injection
barrel, and a material guide post, the press plate is arranged on a top rod of the power element, the
discharge rod is arranged on the press plate, the material guide post sleeves the end part of the
discharge rod, the discharge rod vertically slides relative to the inner wall of the material guide post, the material guide post is fixed on the glue injection
barrel, a Y-shaped material guide hole is formed at the end part of the discharge rod, and a discharge hole is formed in the material guide post. By the blocking-prevention glue
injection device, the problems that the mobility of the
colloid is poor due to the influence of an external environment to further affect the tightness of the battery, generate a leakage phenomenon after injection completion and easily block an injection device during the glue injection process of the battery are solved.
