Description

Technical Field

[0001] The invention relates to the technical field of electrical tools, in particular to an automatic gluing and bonding gun. Background Art

[0002] In the field of electrical tools, hot melt glue guns are commonly used, and using hot melt glue guns to bond the inner membrane of ice packs has become a common alternative method. However, a hand-pulled trigger is used to push the glue stick to supply glue and apply glue. First, the hand-pulled push force is sometimes large and sometimes small, and it cannot be effectively and evenly controlled, resulting in the amount of glue applied being sometimes more and sometimes less, which is not conducive to the bonding of the inner membrane of the ice pack; second, the glue drops or glue piles applied cannot be spread out to dissipate heat, resulting in the melting and perforation of the inner membrane or the debonding of the mucosa, which wastes glue and requires rework; third, applying glue with a hand-pulled trigger is laborious and slow, which increases labor intensity and affects the bonding speed; in short, when using a hot melt glue gun under existing technical conditions to manually apply glue to bond the inner membrane of the ice pack, the labor intensity is high, the production efficiency is low, the work quality is poor, and there is a lack of a dedicated automatic gluing and bonding gun. Summary of the Invention
