A positioning plate 11 is fixedly connected to the left side of the top of the carrier 2, and two positioning pins 12 are fixedly connected to the rear side of the top of the carrier 2. The positioning pin 1 9 is moved to a suitable position according to the size of the plate until the outside of the plate contacts the outside of the positioning pin 1 9, the positioning plate 11 and the positioning pin 2 12, so that the plate can be fixed, and the plate can be positioned and clamped to adapt to the size of the plate to avoid offset during processing;

[0034] Reference Figure 1 and Figure 4 The outsides of the two connecting frames 14 are slidably connected with sliding rings 23, and the adjacent sides of the two sliding rings 23 are fixedly connected with coating plates 24. At this time, the plate is located directly below the coating plates 24. The position of the connecting plate 17 is moved down by the electric slide rail 16. The top of the glue discharge head 22 is fixedly connected with a one-way valve, and the top of the one-way valve is fixedly connected with a connecting pipe. The other end of the connecting pipe is fixedly connected with a storage tank. The one-way valve is started to extract the paint inside the storage tank through the connecting pipe. As the connecting plate 17 moves, the glue discharge head 22 and the top of the coating plate 24 are connected. The top of the two connecting frames 14 are fixedly connected to an electric slide rail 15, the inner sliding connection of the electric slide rail 15 is connected to a slider 1, and the front side of the slider 1 is fixedly connected to an electric slide rail 2 16. Then, the position of the electric slide rail 2 16 is moved by the electric slide rail 15, the inner sliding connection of the electric slide rail 2 16 is connected to a slider 2, and the front side of the slider 2 is fixedly connected to a connecting plate 17. At this time, the electric slide rail 2 16 will drive the connecting plate 17 to move left and right.

[0035] A glue discharge head 22 is fixedly connected to the middle of the connecting plate 17, the outside of the storage tank is fixedly connected to the rear side of the electric slide rail 15, and an adjustment component is arranged on the top rear side of the workbench 1, the adjustment component comprises two connecting rods 18, the outsides of the two connecting rods 18 are respectively slidably connected to the inside of the left and right sides of the connecting plate 17, the top of the connecting rod 18 is fixedly connected to a bottom plate 19, the outside of the connecting rod 18 is sleeved with a spring 20, the bottom of the connecting rod 18 is rotatably connected to a roller brush 21, as the connecting plate 17 moves, the roller brush 21 is driven to roll, the bottom of the sliding collar 23 is fixedly connected to a spring 3 25, the paint is applied to the surface of the coating plate 24, the paint can be evenly applied to the coating plate 24, the other end of the spring 3 25 is fixedly connected to the outside of the connecting frame 14, and one end of the spring 20 is fixedly connected to the top of the connecting plate 17.

[0036] Then continue to use the electric slide rail 2 16 to move the connecting plate 17 downward. The other end of the spring 20 is fixedly connected to the bottom of the bottom plate 19. As the connecting plate 17 continues to move, the connecting rod 18 is forced to move upward to squeeze the bottom plate 19 and the spring 2 20. While the spring 20 is compressed, it will absorb external force and generate a reaction force on the bottom plate 19. At this time, the roller brush 21 also contacts the surface of the coating plate 24, so that the roller brush 21 contacts the surface of the coating plate 24 more closely, squeezing the coating plate 24 to move downward. At this time, the coating plate 24 will drive the sliding ring 23 to squeeze the spring three 25. When the coating plate 24 contacts the plate, the paint is applied to the surface of the plate, making the paint more uniform.

[0037] Working principle: first place the workbench 1 to a suitable position, then place the panel on the placement plate 13 inside the load-bearing platform 2, then start the hydraulic cylinder 3, and the push plate 4 moves upward under the drive of the hydraulic cylinder 3. At this time, the push plate 4 will push the push rod 5 to move upward, and as the push rod 5 moves, it will contact the stop block 8. At this time, the stop block 8 is forced to slide toward the inside of the moving block 6. At this time, the spring 7 is compressed, and at the same time, the positioning pin 9 will slide on the inner wall of the slide groove 10 as the stop block 8 moves. The slide groove 10 will limit the positioning pin 9. According to the size of the panel, the positioning pin 9 is moved to a suitable position until the outside of the panel contacts the outside of the positioning pin 9, the positioning plate 11 and the positioning pin 2 12, so that the panel can be fixed. At this time, the panel is located directly below the coating plate 24, and the position of the connecting plate 17 is moved downward by the electric slide rail 2 16.

[0038] Secondly, the one-way valve is started to extract the paint inside the storage tank through the connecting pipe. As the connecting plate 17 moves, the glue head 22 contacts the top of the coating plate 24, and the paint is applied to the surface of the coating plate 24. At this time, the roller brush 21 also contacts the surface of the coating plate 24. As the connecting plate 17 continues to move, the connecting rod 18 is forced to move upward to squeeze the bottom plate 19 and the spring 20. The spring 20 is compressed and absorbs external force and generates a reaction force on the bottom plate 19, so that the roller brush 21 is in tighter contact with the surface of the coating plate 24. The electric slide rail 15 is then used to move the electric slide rail 2 16. At this time, the electric slide rail 2 16 will drive the connecting plate 17 to move left and right. As the connecting plate 17 moves, the roller brush 21 will roll, so that the paint can be evenly applied to the coating plate 24. Then, the electric slide rail 2 16 is continued to be used to move the connecting plate 17 downward to squeeze the coating plate 24 to move downward. At this time, the coating plate 24 will drive the sliding ring 23 to squeeze the spring three 25. When the coating plate 24 contacts the plate, the paint is applied to the surface of the plate.
