Description

Technical Field

[0001] The utility model relates to the technical field of PCB three-proof paint, in particular to a PCB three-proof paint production device. Background Art

[0002] PCB conformal coating is a protective coating material specially used on the surface of printed circuit boards. Its main function is to protect circuit boards and their components from external factors such as moisture, dust, chemical corrosion and temperature changes in the environment, thereby improving the reliability and life of electronic products.

[0003] When manufacturing PCB conformal paint, it is necessary to load the PCB conformal paint into a barrel, and then use two rollers to rotate the carrying barrel so that the PCB conformal paint is evenly mixed inside the carrying barrel. When mixing the barreled PCB conformal paint, it is necessary to perform light shielding mixing on the PCB conformal paint, so a protective light shielding cover is installed outside the two rollers. However, when driving and mixing carrying barrels of different sizes, it is necessary to change the distance between the two carrying rollers. When further changing the distance between the two carrying rollers, the protective light shielding cover is usually disassembled, and then the carrying roller is released and its position is adjusted. It is inconvenient to simultaneously release the restriction of the carrying roller when releasing the locking state of the light shielding cover. Utility Model Content
