Description

Technical Field

[0001] The utility model relates to the technical field of gluing mechanisms, in particular to an automatic gluing mechanism. Background Art

[0002] Glue dispensing mechanisms are key components in automated equipment used to apply glue or adhesives. They are widely used in industries such as electronics, automotive, aerospace, medical, and packaging. Their core function is to precisely and evenly apply glue or adhesive to specific areas of a workpiece or product to achieve bonding, sealing, or coating protection between components.

[0003] However, existing gluing mechanisms require scraping the surface of the material after applying glue. This can cause excess glue to drip onto the workbench along with the scraper, resulting in glue waste. Furthermore, if the material being applied is elastic, the scraper can have difficulty removing excess glue, resulting in reduced material application quality. Therefore, those skilled in the art have provided an automatic gluing mechanism to address the issues raised in the background art. Utility Model Content

[0011] Preferably, one end of the glue receiving hopper is connected to a delivery pipe, and when the glue in the rubber roller is insufficient, glue can be added to the glue receiving hopper through the delivery pipe.

[0012] (3) Beneficial effects

[0013] Compared with the prior art, the present invention provides an automatic gluing mechanism with the following beneficial effects:

[0014] Through the design, the material to be coated with glue passes through the bottom side of the rubber roller and then passes between the fixed curved plate and the movable curved plate.
