Description

Technical Field

[0001] The utility model relates to the technical field of circuit board processing, in particular to a circuit board gelling machine. Background Art

[0002] After PCBA, the circuit board will be sprayed with glue for protection. The protective glue is applied to the surface of the circuit board to form a thin film that is only 40-60 microns thick and is both light and flexible. It can protect the circuit from damage in conditions such as chemicals (such as fuel, coolant, etc.), vibration, moisture, salt spray, humidity and high temperature, thereby improving and extending the service life of the product and ensuring safety and reliability during use. After spraying, the circuit board can be irradiated with UV light through a gel machine to quickly coagulate the protective glue. However, large gel machines take a long time to arrange the wiring, occupy a large area and have a high initial investment. Therefore, a small gel machine is needed that can be arranged on a workbench as a gel production line to make up for the lack of production capacity. Utility Model Content
