In the adhesive coating process of automobile production, it is not entirely automated by robotic arms, and there are always some areas that are difficult for robotic arms to spray; Thus, manual gluing will be used.
However, in the actual long-term gluing process, there will always be some wear and tear issues with the glue gun, resulting in the glue effect not meeting the requirements; Today, let's take a look at some common problems and related solutions with manual glue guns.
Nozzle overflow glue
Cause: Damage to valve core and seat components Solution: Check and replace valve core and seat components
Cause: Damage to valve seat seal Solution: Check and replace valve seat seal
Cause: Dirty or foreign objects on the sealing surface of the valve core and seat. Solution: Clean the dirty or foreign objects on the sealing surface of the valve core and seat
Rubber overflow from valve core installation hole
Cause: Damaged valve core seal Solution: Check and replace valve core components
Cause: Excessive work pressure Solution: Do not exceed the working pressure of the equipment
Abnormal glue type and amount
Cause: Trigger opening variation Solution: Adjust the trigger opening and lock it
Cause: Damaged nozzle Solution: Check and replace nozzle
Cause: foreign objects or dry glue in the nozzle Solution: Clean the nozzle of dirt or foreign objects
Cause: Large temperature changes in the glue supply system leading to significant changes in glue viscosity. Solution: Improve or adjust the glue temperature control system to stabilize its temperature and viscosity
Cause: System pressure change Solution: Improve or adjust the system pressure control to make it stable
