Description

Technical Field

[0001] The utility model relates to the field of gluing, in particular to an automatic gluing device for cover plates. Background Art

[0002] Currently, during linear gluing, the amount of glue dispensed by the glue gun barrel decreases as the hose capacity decreases. This often requires manual adjustment of the air pressure (increasing the atmospheric pressure) to control the amount of glue applied, making it difficult to precisely control the amount of glue applied. Furthermore, the glue gun must travel along a predetermined gluing route and accurately add the glue to the gluing location. This process requires the correct direction and uniform amount of glue added to achieve the desired gluing effect. However, during the actual gluing process, there can be deviations between the glue gun's path and the direction of the gluing location, leading to errors in the direction of the gluing direction. Errors in recognizing the shape of the gluing location can also lead to errors in the amount of glue added, resulting in overflow and glue breakage. Utility Model Content
