Description

Technical field [0001] The invention relates to the field of automatic spraying, in particular to an automatic spraying production line for hardening paint of a PC face mask of a car lamp. Background technique [0002] Spraying is a coating method in which spray guns or disc atomizers are used to disperse into uniform and fine droplets by means of pressure or centrifugal force and apply to the surface of the object to be coated. It can be divided into air spraying, airless spraying, electrostatic spraying and various derivative methods of the above basic spraying forms, such as large flow and low pressure atomization spraying, thermal spraying, automatic spraying, multi-group spraying, etc. [0003] For the PC face mask of the car light, it must be sprayed with anti-fog paint (hardened paint), that is, a hardened paint layer structure is sprayed on the surface of the car light; in order to meet the needs of the car light anti-fog paint spraying process, corresponding The hardening...

Problems solved by technology

[0005] On the one hand, the spraying station needs to be equipped with an exhaust system during the spraying process. The exhaust system in the spraying room generally draws the outside air into the spraying room through the induced draft fan, and then discharges the indoor air to the outside through the blower. This structure cannot be realized. Recycling of wind, high energy consumption and low utilization rate of resources

[0006] In the second aspect, the infrared curing station includes a drying room, an infrared light source, and a fan, a filtering device and a heating device arranged outside the drying room. The fan, filtering device and heating device are integrated in a box and are all arranged in the Outside the drying room, and the air outlet of the box is set on the left or right side of the drying room to pump the treated air into the drying room. A separate space is required to place the fan, filter and heating device inside. The box body occupies a large area overall, and the space layout is unreasonable, and the treated air enters from the side of the drying room under the action of the circulating fan, so the air inside the drying room forms a lateral flow air channel, and the air crosses the drying room , and finally discharged from the air outlet of the drying room. Due to the small force, the air and dust and other impurities inside the drying room are not easily discharged to the outside of the drying room. Dust and other impurities adhere to the surface of the painted product, resulting in poor spray quality and defective products production, reducing the product qualification rate

However, due to the need to open the automatic door during the feeding process, the ultraviolet light emitted by the ultraviolet light source will be injected into the staff after the automatic door is opened, which can directly cause human eyes and skin damage, such as eyes exposed to short-wave ultraviolet rays, Can cause conjunctivitis and corneal ulcer, that is, electro-optic ophthalmia, which is more harmful to the human body

Therefore, during the ultraviolet drying process, a shading plate is provided in the ultraviolet drying section to block the ultraviolet light from reaching the staff, but because the shading plate is a solid structure, although it can shading, it is not ventilated, and it is inconvenient to use, which is not conducive to the smooth drying of the ultraviolet light. conduct
