The top of the front side and the bottom of the back side of the plate 621 are connected to a slit scraper 622. The right side of the plate 621 is connected to an external coating material pipe. The outer surface of the slit scraper 622 is connected to a slit. Drive motor 63 is fixedly connected to the left side of frame 61, and drive motor 63 is fixedly connected to plate 621. A scraping bracket 64 is fixedly connected to the left side of the frame 61. A motor is fixedly connected to the top of the scraping bracket 64, and a gear is fixedly connected to the back of the motor. The cleaning slide 65 includes a drive scraper 651 slidably connected inside the cleaning bracket 64. A passive scraper 652 is provided on the front of the drive scraper 651. The left side of the drive scraper 651 is fixedly connected to the left side of the passive scraper 652. The top of the drive scraper 651 is provided with teeth. The gear of the motor of the cleaning bracket 64 meshes with the teeth on the top of the drive scraper 651. The cleaning kit 66 is located at the bottom of the cleaning bracket 64. The cleaning kit 66 includes a three-way nozzle 661 fixedly connected to the top of the cleaning bracket 64. The front and back of the three-way nozzle 661 are connected to spray pipes. The left side of the three-way nozzle 661 is connected to an external cleaning liquid pipeline. A collection box 662 is fixedly connected to the bottom of the cleaning bracket 64. A pneumatic vibrator is fixedly connected to the bottom of the collection box 662. Elastic scraper strips are fixedly connected to both sides of the inner wall of the collection box 662. The front of the feed rack 52 is fixedly connected to the front detection group 7, and the back of the feed rack 52 is fixedly connected to the rear detection group 8. The rear detection group 8 is located between the back of the feed rack 52 and the front of the frame 61.

Both the front detection group 7 and the rear detection group 8 are electrically connected to the external control equipment.

[0016] In use, the board to be coated is placed on top of the support plate 2. The device is then activated, and an external suction device extracts the gas between the bottom of the support plate 2 and the inside of the suction seat 3, thus fixing the bottom of the board to the top of the support plate 2 through adsorption. Then, the linear motor 4 drives the spraying assembly 5, the scraping assembly 6, the front detection group 7, and the rear detection group 8 to slide. During this sliding process, the nozzle 54 sprays the coating material onto the board surface. The front detection group 7 detects the distance from the board surface before spraying, thus assisting the hydraulic cylinder in adjusting the distance from the top of the board to the nozzle of the nozzle 54. The rear detection group 8 detects the distance from various positions on the board surface after spraying to the rear detection group 8, thereby providing feedback on the coating thickness and spraying status. Subsequently, the control device controls the drive motor 63 to rotate, adjusting the angle of the flip scraper 62 to achieve secondary scraping of the board surface by the flip scraper 62, improving the coating thickness. To ensure uniformity, after one coat is applied, the drive motor 63, under the control of the control equipment, resets the squeezed scraper 622 that has been coated. The cleaning slide 65 slides to the right under the drive of the motor, and the top of the cleaning slide 65 scrapes and cleans the area coated by the squeezed scraper 622, thereby cleaning the area after the flip-top scraper plate 62 has been coated, ensuring the quality of subsequent coatings. After scraping, the cleaning slide 65 resets. During the period from the reset of the cleaning slide 65 to the completion of the next cleaning process, the three-way nozzle 661 sprays cleaning fluid onto the surface of the cleaning slide 65 for rinsing. The elastic scraper of the collection box 662 scrapes the edge of the cleaning slide 65 under the vibration of the vibrator, scraping away and retaining the cleaning fluid, washed-off coating materials, and impurities. During the coating process, the heating resistor inside the support plate 2 assists the coating process to proceed smoothly through heating, and at the same time, the coating is stress-released through appropriate heating to reduce the adverse effects caused by stress.
