[0024] Specific implementation examples are given below.

[0025] like Figures 1 to 5As shown in the embodiment of this utility model, a circuit board surface coating device includes a processing box 1. The processing box 1 has an inlet 11 and an outlet 12 sequentially opened on its side wall. A support frame 13 is fixedly connected to the inner wall of the processing box 1. A servo motor 14 is fixedly connected to the surface of the processing box 1. A lead screw 15 is fixedly connected to the output end of the servo motor 14. The lead screw 15 is through-mounted and rotatably connected to the support frame 13. A slider 16 is threadedly connected to the middle of the lead screw 15. A transmission pipe 17 is connected to the top of the slider 16. The transmission pipe 17... The pipe 17 is slidably connected to the processing box 1; multiple nozzles 18 are connected to the bottom of the slider 16; a pair of cleaning cloths 19 are fixedly connected to the inner wall of the support frame 13; a conveyor belt 101 is provided at the bottom of the processing box 1; multiple locking blocks 102 are fixedly connected to the surface of the conveyor belt 101; during operation, the workpiece is first placed inside the processing box 1 and then pressed between the locking blocks 102 to fix the workpiece, and then the transmission pipe 17 is connected to the paint tank so that the paint enters the slider 16 through the transmission pipe 17 and thus reaches the processing box 16. The nozzle 18 sprays paint onto the workpiece. During spraying, the servo motor 14 is started, causing the lead screw 15 to rotate. As the lead screw 15 rotates, it moves the slider 16. The paint sprayed from the nozzle 18 moves along the workpiece surface, thus coating the workpiece. After spraying is complete and paint transfer stops, the nozzle 18 comes into contact with the cleaning cloth 19. The cleaning cloth 19 absorbs any remaining paint on the nozzle 18, cleaning it and reducing paint dripping. Subsequently, each time the slider... When the nozzle 16 reaches the end of the support frame 13, the nozzle 18 will be cleaned. After the spraying is completed, the conveyor belt 101 will be started to move the workpiece to the discharge port 12 for removal. By moving the slider 16, the nozzle 18 can be moved to carry out full spraying on the workpiece surface. At the same time, the cleaning cloth 19 will clean the nozzle 18 when it moves to the end of the support frame 13, thereby reducing the amount of paint remaining on the nozzle 18 and reducing the amount of paint dripping when spraying the next workpiece, thus improving the spraying effect on the workpiece.

[0026] like Figure 2 As shown, a scraper 2 is fixedly connected to the middle of the processing box 1; the end of the scraper 2 is set with an inclined surface; multiple round holes 21 are opened on the surface of the scraper 2; during operation, when the workpiece is sprayed, the thicker area of ​​the spray will contact the end of the scraper 2. At this time, the end of the scraper 2 will scrape the paint, causing it to move upwards and enter the interior of the scraper 2 through the round holes 21, thereby scraping and collecting the paint; by adding a scraper 2, when there is a lot of paint, it can be scraped by the scraper 2, thereby reducing the paint thickness and thus reducing the impact on the spraying effect, allowing the excess paint to enter the interior of the scraper 2, thereby increasing the uniformity of spraying.

[0027] like Figure 2As shown, a cylinder 3 is fixedly connected to the top of the processing box 1; a heating plate 31 is fixedly connected to the output end of the cylinder 3; during operation, after the workpiece is sprayed, the heating plate 31 can be started first to heat the workpiece, and then the cylinder 3 can be started to push the heating plate 31 downward. At this time, the distance between the heating plate 31 and the workpiece can be controlled to dry the coating on the surface of the workpiece, thereby accelerating the solidification of the coating; by adding the heating plate 31, the workpiece can be dried, and the distance between the heating plate 31 and the workpiece can be controlled by the cylinder 3, thereby controlling the degree of heating of the workpiece by the heating plate 31, making it more flexible and thus quickly processing the coating.

[0028] like Figure 4 As shown, a collection box 4 is fixedly connected to the bottom of the support frame 13; the collection box 4 and the cleaning cloth 19 are correspondingly arranged; during operation, when the cleaning cloth 19 has been working for a long time, a large amount of paint will be inside and drip down. When the paint drips down, it will enter the collection box 4, thereby collecting the paint; by adding the collection box 4, the paint can be collected when the cleaning cloth 19 drips paint, thereby reducing paint scattering and thus collecting the paint in a concentrated manner.

[0029] like Figures 3 to 4 As shown, multiple spring telescopic rods 5 are fixedly connected to the side wall of the support frame 13; a push plate 51 is fixedly connected to the end of each spring telescopic rod 5; a connecting rod 52 is fixedly connected to the middle of the push plate 51; the connecting rod 52 is through-mounted and slidably connected to the support frame 13; a cleaning plate 53 is fixedly connected to the end of the connecting rod 52; the cleaning plate 53 and the cleaning cloth 19 are correspondingly arranged; during operation, when there is a lot of paint inside the cleaning cloth 19, the push plate 51 can be pushed to drive the cleaning plate 53 to move along the surface of the cleaning cloth 19, thereby pushing the paint on the surface of the cleaning cloth 19 to accumulate and quickly fall into the collection box 4, so that the paint inside the cleaning cloth 19 is collected; by adding spring telescopic rods 5, the paint on the surface of the cleaning cloth 19 can be cleaned to speed up its entry into the collection box 4, thereby reducing the impact of the cleaning cloth 19 on the cleaning of the nozzle 18.

[0030] like Figure 5 As shown, a rubber pad 6 is fixed to the inner wall of the locking block 102; the rubber pad 6 and the locking block 102 are correspondingly arranged; during operation, when the workpiece is installed, it will first contact the rubber pad 6 when it comes into contact with the locking block 102. At this time, the workpiece will squeeze the rubber pad 6, and the rubber pad 6 will deform, thereby increasing the contact between the locking block 102 and the workpiece; by adding the rubber pad 6, the contact area between the workpiece and the locking block 102 can be increased, thereby increasing the stability during fixing.

[0031] Working principle: First, the workpiece is placed inside the processing box 1 and then pressed between the clamping blocks 102 to fix the workpiece. Then, the transmission pipe 17 is connected to the paint tank, allowing the paint to enter the slider 16 through the transmission pipe 17 and reach the nozzle 18 to be sprayed onto the workpiece. When spraying, the servo motor 14 is started, causing the servo motor 14 to drive the lead screw 15 to rotate. When the lead screw 15 rotates, it drives the slider 16 to move. At this time, the paint sprayed from the nozzle 18 moves along the surface of the workpiece, thus coating the workpiece. The workpiece is sprayed. After spraying is completed and the paint transfer is stopped, the nozzle 18 will come into contact with the cleaning cloth 19. At this time, the cleaning cloth 19 will absorb the residual paint on the nozzle 18, thereby cleaning the nozzle 18 and reducing paint dripping. Subsequently, the nozzle 18 will be cleaned every time the slider 16 reaches the end of the support frame 13. After spraying is completed, the conveyor belt 101 will be started to move the workpiece towards the discharge port 12 for removal. When the workpiece is sprayed, the thicker areas will come into contact with the end of the scraper 2. At this time, the end of the scraper 2 will remove the paint. The coating is scraped and moved upwards to the scraper 2, entering the scraper 2 through the round hole 21, thus scraping and collecting the coating. After the workpiece is sprayed, the heating plate 31 can be activated to heat it, and then the cylinder 3 can be activated to push the heating plate 31 downwards. At this time, the distance between the heating plate 31 and the workpiece can be controlled to dry the coating on the workpiece surface, thereby accelerating the solidification of the coating. When the cleaning cloth 19 has been working for a long time, a large amount of coating will accumulate inside and drip down. The dripping coating will enter the collection box 4, thus collecting the coating. When there is a lot of coating inside the cleaning cloth 19, the pusher 51 can be pushed to move the cleaning plate 53 along the surface of the cleaning cloth 19, thereby pushing the coating on the surface of the cleaning cloth 19 to accumulate and quickly fall into the collection box 4, thus collecting the coating inside the cleaning cloth 19. When installing the workpiece, when it comes into contact with the clamping block 102, it will first contact the rubber pad 6. At this time, the workpiece will squeeze the rubber pad 6, and the rubber pad 6 will deform, thereby increasing the contact between the clamping block 102 and the workpiece.

[0032] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model.
