Description

Technical Field

[0001] The invention belongs to the field of PCB board processing, and particularly relates to a device structure for detecting protective paint coated on a PCB board during PCB board processing and production. Background Art

[0002] Since PCBs encounter various pollutants generated by the environment during operation, such as dust, oil, moisture, salt spray, corrosive gases, etc., these pollutants can damage the PCBs, thereby causing the components of the PCBs to fail to function. In order to resist this corrosive environment, the industry currently applies a layer of protective paint on the PCBs to effectively isolate the components of the PCBs from the external environment. The industry's coating methods for PCBs are brushing and spraying; and these methods may have the situation of missing brushing or spraying, so the brushing condition of the PCBs must be tested. The traditional detection method is manual detection, placing the PCB under a UV lamp, and then manually detecting the coating condition of the three-proof paint. This method not only increases labor costs, but also has low efficiency, and long-term workers are under the irradiation of UV lamps (UV lamps) for a long time, which poses a health hazard.

[0003] For example, the comparative document 1 with the patent application number "201810483942.8" discloses an all-in-one dispensing and detection machine, including: a base frame, on which a processing platform is provided; a dispensing valve, arranged above the processing platform; an XYZ three-axis drive device, arranged in the processing space and mechanically connected to the dispensing valve; a conveying device, arranged on the processing platform, located below the dispensing valve; including an image acquisition device, arranged next to the dispensing valve, which automatically performs image acquisition, information storage and feedback on the dispensing station after the dispensing valve sprays glue; a light source, arranged next to the image acquisition device, for providing the required light waves; a control system, which receives the image information fed back by the image acquisition device and compares it with the standard information stored in the system. Although the comparative document 1 realizes automatic detection of PCB boards and reduces manual work, in the comparative document 1, although there is an image acquisition device to detect the PCB boards, the purpose is to detect whether the dispensing process of the PCB boards is qualified, which is different from the purpose of detecting the coating condition of the three-proof paint. Based on this purpose, the technical solution implemented by the device is to set the image acquisition device next to the dispensing valve, and perform image acquisition and detection on one side of the dispensing surface after the dispensing valve is completed. When detecting the coating condition of the three-proof paint, this technical solution cannot complete the complete detection of the three-proof paint coating on both sides of the PCB board in the same process. Summary of the invention

[0004] In order to solve the above problems, the purpose of the present invention is to provide a UV detection device with a flipping function that can detect the three-conformal paint coating conditions on both sides of the PCB board, replace manual operation, save labor costs, and avoid the impact of the three-conformal paint on human health and the misdetection and missed detection of manual detection.

In the present device, the coating conditions of the three-conformal paint coating on both sides of the PCB board can be continuously detected, replacing manual operation, which has the advantages of saving labor costs and avoiding the impact of the three-conformal paint coating on human health. At the same time, the coating condition is automatically detected by the device to prevent the occurrence of false detection and missed detection in manual detection.

[0044] The beneficial effect of the present invention is that, compared with the prior art, in the present invention, the PCB board is transmitted by the transmission mechanism, and after the UV detection mechanism performs UV illumination and detection on one side of the PCB board entering the device, the PCB board is flipped by the flipping mechanism, and the other side of the PCB board is also subjected to UV illumination and detection. In the present device, the coating conditions of the three-conformal paint coating on both sides of the PCB board can be continuously detected, replacing manual operation, which has the advantages of saving labor costs and avoiding the impact of the three-conformal paint coating on human health. At the same time, the coating condition is automatically detected by the device to prevent the occurrence of false detection and missed detection in manual detection.
