A variety of types of glues can be used in coating machines, including water-based glues, solvent-based glues, hot melt glues, and UV glues, etc. UV glues can be cured under the action of ultraviolet rays.

The bottom end of the substrate placement plate 10 is connected to an electric push rod 9. The bottom end of the electric push rod 9 is fixed to the fixed bottom plate 1. Blocking blocks 14 are fixed to both ends in the short side direction of the groove 11. A substrate can be placed between the two blocking blocks 14. By starting the electric push rod 9, the electric push rod 9 can be lowered, facilitating the operator to place the substrate in the groove 11. The two ends of the substrate are blocked by the two blocking blocks 14. After the placement is completed, glue can be manually applied to the substrate. Then, the electric push rod 9 can drive the substrate to rise, and the glue on the substrate can be leveled by the glue scraping mechanism.

[0023] The present utility model uses UV glue for the gluing work.

[0024] A groove 11 is opened at the top end of the substrate placement plate 10. The length of the slide rail 2 is longer than the length of the substrate placement plate 10. One end of the substrate placement plate 10 is connected to a collection box 13.

[0025] Side panels 6 are fixed to both ends of the slide rail 2. A lead screw 8 is rotatably connected between the two side panels 6. A slider 7 is arranged on the lead screw 8. A threaded hole is arranged on the slider 7. The threaded hole is in cooperation connection with the lead screw 8. A moving block 4 is slidably engaged with the slide rail 2. The moving block 4 and the slider 7 are fixedly connected.

[0026] The glue scraping mechanism includes a U-shaped plate 15 and a scraping plate 16. The U-shaped plate 15 is fixed to both sides of the moving block 4, and the scraping plate 16 is fixed to the bottom end of the U-shaped plate 15. Moreover, the width of the scraping plate 16 is the same as the width of the groove 11. One side panel 6 is fixedly connected to a driving motor 5 on the side away from the lead screw 8, and one end of the lead screw 8 is fixedly connected to the rotating shaft on the driving motor 5.

[0027] In the actual operation of the present utility model, after the driving motor 5 is started, it can drive the lead screw 8 to rotate. When the lead screw 8 rotates, the matching slider 7 can move along the length direction of the lead screw 8. While the slider 7 is moving, it drives the corresponding moving block 4 to slide on the slide rail 2. And when the moving block 4 moves, it drives the scraping plate 16 to move. The scraping plate 16 moves from one end of the substrate placement plate 10 to the other end of the substrate placement plate 10, scraping and leveling the upper surface of the substrate in the placement groove 11, preventing the glue from accumulating together, and playing a role in evenly covering the surface of the substrate with glue.

[0030] In the actual operation of the present utility model, after the substrate is leveled by the scraping plate 16, the substrate descends by the retraction of the electric push rod 9. At this time, the ultraviolet laser works and emits ultraviolet light in parallel in a very short time. If there is no UV glue or protrusion on the surface of the substrate to block the light, the light receiver in the light receiving groove 17 will receive the light at this time. Without obstruction, the intensity of the emitted light does not change significantly, and the irradiation time of the ultraviolet laser can be extended so that the ultraviolet light is on the upper surface of the glue to cure the glue. If there are protrusions on the surface of the substrate that block the light due to uneven application of the glue, when there is glue to block the light, the light will be scattered, and the intensity of the light will adaptively decrease with the glue of different transparencies. After the light receiver in the light receiving groove 17 receives the decrease in the light intensity, it controls the electric push rod 9 to rise, and the scraping plate 16 levels the surface of the substrate again to play a corrective role.
