Description

Technical Field

[0001] This utility model relates to the field of automotive roof processing technology, and in particular to an automotive roof adhesive spraying tool. Background Technology

[0002] The car roof is an important part of the vehicle's interior, usually referring to the covering on the top of the car. It not only provides a certain aesthetic appeal to the vehicle, but also provides functions such as sound insulation, sound absorption, and heat insulation. Car roofs are usually made of fabric, synthetic leather, or other soft materials. Sometimes, hard materials (such as plastics or composite materials) can be used to enhance structural strength. The trim layer is generally bonded to the semi-finished injection-molded car roof parts through hot pressing. Before bonding, adhesive needs to be applied to the bonding surface.

[0003] Currently, the lack of precise fixing and adjustment mechanisms for automotive headliners during adhesive spraying leads to potential positional shifts or instability, affecting spraying accuracy and consistency. Height differences during headliner installation and removal require manual compensation, and the open spraying environment poses a safety hazard to surrounding workers. Therefore, this invention proposes an automotive headliner adhesive spraying fixture to address the problems mentioned in the background. Utility Model Content

[0024] 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.

[0025] Reference Figure 1-4, an automotive ceiling spraying tooling, including a spraying chamber 1. A spraying rack 2 is arranged on the front side of the spraying chamber 1. The spraying rack 2 slides inside and outside on the front side of the spraying chamber 1. A vertically sliding bracket 19 is arranged on the front side of the spraying rack 2. A number of supporting rods are arranged inside the bracket 19. Side frames 7 that slide on the supporting rods are arranged on both sides of the bracket 19. The left and right lower ends of the side frames 7 slide on the inner supporting rods of the bracket 19. Tightening bolts 8 corresponding to the supporting rods are threadedly connected to the outer sides of both ends of the side frames 7. Place the ceiling to be sprayed on the bracket 19 with the interior surface facing up. Then slide the left and right side frames 7 of the bracket 19 to make the two side frames 7 clamp the middle ceiling. By tightening or loosening the tightening bolts 8, the position of the side frames 7 on the bracket 19 is fixed, thereby completing the left and right fixation of the ceiling for later spraying operation of the ceiling;

[0026] Furthermore, first-stage spur gears 3 are installed on the left and right lower sides of the spraying rack 2. Tooth grooves meshing with the first-stage spur gears 3 are arranged on the left and right of the front side of the spraying chamber 1. Second-stage spur gears 4 are arranged on the upper sides of the two first-stage spur gears 3. The second-stage spur gears 4 are rotatably connected to the inner side of the spraying rack 2. Vertical racks are fixed on the left and right of the rear side of the bracket 19. The two vertical racks respectively mesh with the two second-stage spur gears 4 correspondingly. Synchronous pulleys 5 are fixed on the inner sides of the first-stage spur gears 3 and the second-stage spur gears 4. A corresponding synchronous belt 6 is sleeved outside the two synchronous pulleys 5. After the above-mentioned ceiling is assembled, push the spraying rack 2 into the spraying chamber 1. During the forward movement, the first-stage spur gears 3 on the left and right lower sides of the spraying rack 2 rotate. The first-stage spur gears 3 drive the synchronous pulleys 5 fixed on the inner sides to rotate. Through the other synchronous pulley 5 and the corresponding synchronous belt 6 outside, the linkage to the upper second-stage spur gears 4 is achieved. The second-stage spur gears 4 make the bracket 19 on the front side of the spraying rack 2 move upward through the meshing vertical racks, driving the ceiling to rise to correspond to the spray gun inside the spraying chamber 1

[0027] Even further, a glue tank 10 is fixedly installed above the inside of the spraying chamber 1. Movable seats 9 are arranged on the left and right of the lower side of the glue tank 10. The movable seats 9 slide left and right on the spraying chamber 1. A number of spray nozzles 11 are installed inside the movable seats 9. Telescopic hoses are connected between the spray nozzles 11 and the upper glue tank 10. The side surface of the movable seat 9 is in a "匚" shape. Pushing cylinders 18 are installed on the inner sides of the spraying chamber 1. The output shafts of the pushing cylinders 18 are fixedly connected to the movable seats 9. The lower ends of the movable seats 9 are located below the bracket 19. After pushing the above-fixed ceiling into and rising it to the inside of the spraying chamber 1, start the two pushing cylinders 18. The pushing cylinders 18 push the movable seats 9 into the spraying chamber 1. The lower ends of the movable seats 9 move to the left and right lower sides of the bracket 19, realizing the lifting effect on the bracket 19 and assisting in supporting the ceiling on the bracket 19;

[0028] Furthermore, rotating rods 12 are rotatably connected to the left and right sides of the inner side of the movable seat 9, and pressure frames 13 are rotatably connected to the outer ends of the rotating rods 12. A second bevel gear 16 is fixed to the inner side of the rotating rod 12, and a corresponding bevel gear 15 is provided on the upper side of the second bevel gear 16. Both the first bevel gear 15 and the second bevel gear 16 are rotatably connected to the movable seat 9. A third spur gear 14 is fixed to the upper side of the first bevel gear 15, and a corresponding gear seat 17 is provided on the inner side of the third spur gear 14. The gear seat 17 is fixed inside the glue spraying chamber 1. A torsion spring is provided at the junction of the pressure frame 13 and the rotating rod 12. When the movable seat 9 is pushed inward, the third spur gear 14 on the inner side of the movable seat 9 meshes with the corresponding gear seat 17, causing the third spur gear 14 to rotate. The spur gear 14 drives the lower fixed bevel gear 15 to rotate, which in turn drives the lower fixed bevel gear 15 to rotate. The bevel gear 15 drives the lower meshing bevel gear 16, which in turn drives the inner fixed rotating rod 12 to rotate. The rotating rod 12 is then brought close to the front and rear of the ceiling via the pressure frame 13 on its lower side. The torsion spring on the rotating rod 12 provides a buffer gap, and when the pressure frame 13 is close to the front and rear of the ceiling, the torsion spring is also tightened. In this way, while the movable seats 9 on both sides support the bracket 19, the nozzle 11 corresponds to the ceiling spraying position and is linked to the front and rear pressure frame 13 structure, achieving the effect of stabilizing the ceiling and facilitating better glue spraying on the ceiling.

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.
