[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0021] Example 1, referring to Figure 1 and Figure 2 An automatic adhesive spraying device for a seat back panel includes a workbench 1, a robotic arm 2 fixedly connected to the left side of the workbench 1, an adhesive spraying assembly threadedly connected to the output end of the robotic arm 2, a transmission assembly fixedly connected to the upper surface of the workbench 1, and an adhesive bonding assembly fixedly connected to the right side of the workbench 1. The adhesive spraying assembly includes an internally threaded glue cylinder 3, with a glue spray nozzle 4 fixedly connected to the right end of the internally threaded glue cylinder 3. The transmission assembly includes an electric slide rail 5, with a slider 6 slidably connected to the inner wall of the electric slide rail 5, and a support tray 7 fixedly connected to the upper surface of the slider 6. The seat back panel is placed in the support tray 7. The robotic arm 2 can drive the adhesive spraying assembly to move above the back panel, and at the same time, the glue spray nozzle 4 sprays the glue in the internally threaded glue cylinder 3 onto the surface of the back panel. No manual glue spraying operation is required. After the glue spraying is completed, the electric slide rail 5 drives the back panel to move quickly below the adhesive bonding assembly via the slider 6.

[0022] The adhesive assembly includes a positioning frame 8, a drive motor 9 fixedly connected to the upper surface of the positioning frame 8, a lead screw 10 fixedly connected to the output end of the drive motor 9, a sliding groove formed on the side of the positioning frame 8, the bottom end of the lead screw 10 extending into the interior of the sliding groove and rotatably connected to the inner bottom wall of the sliding groove, a convex block 11 slidably connected to the inner wall of the sliding groove, a screw hole formed on the upper surface of the convex block 11, the convex block 11 being threadedly connected to the lead screw 10 through the screw hole, a U-shaped frame 12 fixedly connected to the left side of the convex block 11, a round rod 13 rotatably connected to the front side of the U-shaped frame 12, a rotating rod 14 rotatably connected to the inner wall of the U-shaped frame 12, and a pressure plate 15 fixedly connected to the front end of the rotating rod 14, and the rear end of the round rod 13 connected to the pressure plate 15. The front of the frame is fixedly connected. The drive motor 9 can drive the U-shaped frame 12 and the pressure plate 15 to descend through the lead screw 10 and the convex block 11. The upper surface of the pressure plate 15 is fixedly connected to the vacuum pump 16, and the lower surface of the pressure plate 15 is provided with a slot. The inner wall of the slot is fixedly connected to four vacuum suction cups 17. All four vacuum suction cups 17 are connected to the vacuum pump 16 through pipes. The vacuum suction cups 17 adsorb the seat leather. At the same time, when descending, the pressure plate 15 can be inserted into the support tray 7, so that the leather can correspond to the position of the back panel. At the same time, the leather is pressed onto the surface of the back panel by the pressure plate 15, and the glue will not solidify for a long time. The front of the U-shaped frame 12 is provided with a circular groove, and the inner wall of the circular groove is slidably connected to a limit component.

[0023] Example 2: Refer to Figure 3 The limiting component includes a pull rod 18, with a limiting plate 19 fixedly connected to the rear end of the pull rod 18. A spring 20 is sleeved on the surface of the pull rod 18. The front end of the spring 20 overlaps with the inner wall of the U-shaped frame 12, and the rear end overlaps with the front of the limiting plate 19. The front of the pressure plate 15 has two limiting slots that are adapted to the limiting plate 19. When it is necessary to feed the leather, simply pull the pull rod 18 forward so that the pull rod 18 drives the limiting plate 19 to disengage from the limiting slots. At this time, the pressure plate 15 can rotate through the round rod 13 and the rotating rod 14. At the same time, the limiting plate 19 causes the spring 20 to deform. After the pressure plate 15 rotates 180 degrees, the pull rod 18 is released. At this time, the spring 20 generates a reaction force and drives the limiting plate 19 to be inserted into the limiting slot, positioning the pressure plate 15. This facilitates the feeding operation for the staff and improves stability.

[0024] Working principle: First, the operator places the seat back panel on the support tray 7 and pulls the lever 18 forward. The lever 18 causes the limiting plate 19 to disengage from the limiting slot on the front of the pressure plate 15, and simultaneously causes the spring 20 to deform. At this time, the pressure plate 15 is no longer restricted and can be rotated by the round rod 13. The pressure plate 15 is rotated 180 degrees, so that the four vacuum suction cups 17 are in the upper position. The operator places the seat leather in the pressure plate 15 and starts the vacuum pump 16. The vacuum pump 16 sucks out the air from the four vacuum suction cups 17, so that the vacuum suction cups 17 can firmly adhere the leather. The operation is then repeated to make the pressure plate 15 move the leather to the lower position. The process begins with opening the adhesive spraying assembly. The robotic arm 2 moves the adhesive spray nozzle 4 above the back panel, while the nozzle 4 sprays adhesive from the internally threaded adhesive cylinder 3 onto the back panel surface. After the adhesive spraying is complete, the electric slide rail 5 quickly moves the carrying tray 7 and the adhesive-sprayed back panel to the right side of the adhesive bonding assembly via the slider 6. The drive motor 9 then lowers the U-shaped frame 12 via the lead screw 10 and the convex block 11, thereby lowering the pressure plate 15 and the leather material. The pressure plate 15 engages with the carrying tray 7, bringing the leather material into contact with and pressing it against the back panel, thus completing the adhesive bonding operation. This process ensures that the adhesive does not solidify during long-term transport, improving the production quality of the automotive seats.

[0025] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
