Full-automatic paint spraying machine

Abstract

The invention discloses an automatic paint spraying machine. The automatic paint spraying machine comprises a guide rail transportation system, a paint spraying system, a drying system, a cooling system and a control system, wherein the paint spraying system, the drying system and the cooling system are mounted on the guide rail transportation system in sequence; and the paint spraying system comprises a paint sprayer and an induction device. The automatic paint spraying machine automatically transports PCBs into the paint spraying system through the guide rail transportation system; the paint spraying system realizes automatic paint spraying through the induction of the induction device; after the paint spraying is finished, the PCBs enter the drying system; the drying system sets the temperature for drying according to the sizes and the humidity of the boards; and after the drying is finished, the PCBs enter the cooling system for cooling to room temperature. The automatic paint spraying machine has such advantages as high production efficiency, automatic production, reduction of labor intensity, uniform paint coating, high paint spraying quality, uniform heating of the PCBs and good drying effect.

Description

technical field [0001] The invention relates to an LED outdoor screen module PCB board painting equipment, in particular to a fully automatic painting machine. Background technique [0002] The application of electronic products has penetrated into all aspects of life, and people's requirements for the manufacture of electronic products are getting higher and higher. Conformal paint is a special formula coating used to protect PCB boards and related equipment from environmental erosion , so as to improve and prolong their service life and ensure the safety and reliability of use. [0003] Under realistic conditions, such as chemical, vibration, high dust, salt spray, humidity and high temperature environments, PCB boards may have corrosion, softening, deformation, mildew and other problems, resulting in circuit board circuit failures. The three-proof paint is coated on the surface of the circuit board to form a layer of three-proof protective film (three-proof refers to moi...

AI Technical Summary

Problems solved by technology

At present, in the known field, the painting of PCB boards is mostly processed by manual spray guns. The painting requires manual operation, and there is a phenomenon of uneven thickness and thickness of the painting, and whether the system coating is uniform, whether the coating thickness is appropriate, and the coating efficiency. Unstable high and low

After the manual painting is finished, it needs to be placed on the drying rack to wait for drying. The production efficiency is low and it cannot be automated.
