Problems solved by technology

[0003] In the existing spraying equipment, the coordinate system is usually set first, and then the nozzle is moved according to the coordinate system. After moving to the corresponding coordinates, spraying is carried out in a direction perpendicular to the PCB board. This spraying method is suitable for spraying some large areas. There is a disadvantage of low efficiency when spraying PCB boards. When spraying some special-shaped boards, for example, when a horizontal board and a vertical board are welded together, since components are welded on both boards, the connection of the two boards It is inevitable that there will be a dead angle of spraying, which will affect the spraying effect. In the existing products, it is usually necessary to design a more complicated nozzle structure to spray such special-shaped plates.
Therefore, the existing spraying device has the defects of complex design, low spraying efficiency and poor spraying effect

Embodiment Construction

[0023] The present invention will be described in more detail below in conjunction with the accompanying drawings and embodiments.

[0024] The invention discloses a three anti-paint spraying device, which combines figure 1 and figure 2 As shown, it includes a spraying assembly 1 that can rise and fall and a conveying assembly 2 located below the spraying assembly 1. The spraying assembly 1 includes a crossbeam 10, two horizontal rails 11 that are slidably connected with the crossbeam 10 and are located on A plurality of spray guns 12 on a beam 10 capable of rotating along its axis. In the above-mentioned structure, when the PCB board 3 is carried on the conveying assembly 2 and conveyed to the spraying position, the appropriate spraying distance is reached through the rise or fall of the spraying assembly 1, and then the beam 10 slides back and forth on the two horizontal rails 11, so that The spray gun 12 can evenly spray the conformal paint on the entire PCB board 3 . W...

Abstract

The invention discloses a moistureproof, mildewproof and anti-static spraying device which comprises a spraying component capable of ascending and descending and a delivery component arranged below the spraying component, wherein the spraying component comprises a cross beam, two horizontal tracks connected with the cross beam in a sliding manner, and a plurality of spraying guns arranged on the cross beam, and the cross beam can rotate along the axis line of the cross beam. Compared with the prior art, the moistureproof, mildewproof and anti-static spraying device is simple in structure and has higher spraying efficiency and better spraying effect.

Description

technical field [0001] The invention relates to the technical field of circuit board spraying, in particular to a conformal paint spraying device. Background technique [0002] With the wide application of electronic products in daily life and industrial production, people have higher and higher performance requirements for electronic products. In addition to strict requirements on circuit functions, the reliability of products and moisture-proof, mildew-proof, anti-static etc. have also put forward higher requirements. In order to meet the above requirements, many companies spray conformal paint on the surface of the PCB after welding the PCB to improve the life and reliability of the PCB. [0003] In the existing spraying device, the coordinate system is usually set first, and then the nozzle is moved according to the coordinate system. After moving to the corresponding coordinates, spraying is carried out in a direction perpendicular to the PCB board. This spraying metho...
