Description

Technical Field

[0001] This invention relates to the field of decorative strips, and more particularly to an apparatus for painting automotive decorative strips. Background Technology

[0002] Car trim strips serve to decorate and beautify vehicles, and their decorative effect directly affects the interior and exterior image of the car. Based on the actual condition of the car and adhering to the principles of aesthetics, harmony, practicality, and safety, trim strips should be selected selectively to ensure the desired decorative effect. During the manufacturing and processing of trim strips, they are placed in tooling for painting.

[0003] Patent application number CN202420934025.8 discloses a high-efficiency spraying device for producing automotive trim strips, including a body and a spraying device. A movable plate is movably mounted at one end of the body, and a fixed clamp is fixedly mounted at one end of the movable plate. A movable clamp is movably mounted at one end of the movable plate, and an extension plate is fixedly mounted at one end of the movable clamp. A first rack is fixedly mounted at one end of the extension plate. A first rotating rod is movably mounted inside the body, and a first gear meshing with the first rack is fixedly mounted at one end of the first rotating rod. A first limiting block is fixedly mounted at one end of the movable plate, and a fixed bracket is fixedly mounted at one end of the first limiting block. A push plate is movably mounted inside the fixed bracket, and a second rack is fixedly mounted at one end of the push plate. A second rotating rod is movably mounted inside the body, and the first gear and the second rack are connected through the second rotating rod. An auxiliary spraying device is fixedly mounted inside the fixed clamp. The worker presses the car trim strip to be painted into the space between the fixed and movable clamps. A second spring applies elastic force to the movable clamp, initially restricting the trim strip. The worker then pushes the handle and push plate, allowing the movable plate to enter the machine. The painting equipment is then started to paint the trim strip. After painting, the trim strip is removed. However, because the paint needs time to dry, removing it before it dries can damage the paint surface. Waiting for it to dry takes a long time, resulting in low production efficiency.

[0004] This invention was proposed in response to the shortcomings of existing technologies. Summary of the Invention

[0005] The purpose of this invention is to overcome the shortcomings of the prior art and provide an automotive trim spraying device.

[0006] This invention can be achieved through the following technical solutions: This invention discloses a car trim painting device, comprising a frame with conveyor shafts on both sides of the frame. The conveyor shafts are driven to rotate by a conveyor motor. Sprockets are fixed on both sides of the conveyor shafts, and the sprockets at corresponding positions on both sides of the two conveyor shafts are connected by chains. Multiple fixing modules are evenly fixed between the two chains. A painting device is also fixed on the frame. The painting device includes a lead screw and a slide rod mounted on the frame. The lead screw is driven to rotate by a painting motor. A slide rod with a threaded connection to the lead screw is mounted on the lead screw. A spray head is fixed at the bottom of the slide rod. A protective cover is also fixed on one side of the frame of the painting device. Multiple dark blue LED tubes connected to an external power source are evenly fixed inside the protective cover.

[0007] Preferably, fans are also evenly fixed on one side of the protective cover of the dark blue LED tube. The fans draw out the hot air from inside the protective cover, achieving air circulation and preventing heat accumulation that could damage the dark blue LED tube.

[0008] Preferably, a baffle is also fixed on the frame below the protective cover. The baffle below the protective cover blocks light and prevents light pollution.

[0009] Compared with existing technologies, the present invention has the following advantages: This device can quickly spray paint on decorative strips. After spraying, the paint surface is quickly cured by high-intensity UV light, so there is no need to worry about damaging the paint surface when removing the decorative strip.

[0011] The embodiments of the present invention will now be described in detail with reference to the accompanying drawings: Example

[0012] like Figures 1 to 3As shown, this embodiment discloses an automotive trim painting device, comprising a frame 1, with conveyor shafts 2 on both sides of the frame 1. The conveyor shafts 2 are driven to rotate by a conveyor motor 4. Sprockets 3 are fixed on both sides of the conveyor shafts 2. The sprockets 3 at corresponding positions on both sides of the two conveyor shafts 2 are connected by chains 5. Multiple fixing modules 6 are evenly fixed between the two chains 5. A painting device 7 is also fixed on the frame 1. The painting device 7 includes a lead screw 8 and a slide bar 9 set on the frame 1. The lead screw 8 is driven to rotate by a painting motor 10. A slide plate 11 threadedly connected to the lead screw 8 is set on the lead screw 8. A spray nozzle 12 is fixed at the bottom of the slide plate 11. A protective cover 13 is also fixed on one side of the frame 1 of the painting device 7. Multiple dark blue LED tubes 14 connected to an external power source are evenly fixed inside the protective cover 13. Decorative strips are placed sequentially in the fixed slots of each fixed module 6, with the side to be painted facing upwards. The conveyor motor 4 drives the conveyor shaft 2 to rotate. As the conveyor shaft 2 rotates, the chain 5 rotates, causing each fixed module 6 to move. The decorative strips move with each fixed module 6. After the decorative strips reach below the painting device 7, the spray nozzle 12, connected to the paint tank via a conduit with a pump fixed to it, draws UV-cured paint from the paint tank and sprays it through the spray nozzle 12 to paint the decorative strips. The painting motor 10 drives the lead screw 8 to rotate, and the slide plate 11 moves from one end of the lead screw 8 to the other end, with the spray nozzle 12 moving along with the slide plate 11. The device operates by spraying paint onto the decorative strip using the nozzle 12. After painting, the conveyor motor 4 drives the chain 5 to rotate again, and the decorative strip moves into the protective cover 13 along with the chain 5. Then, the dark blue LED tube 14 is powered on and emits high-intensity UV light. The UV curing paint is quickly cured by irradiating it with the UV light. After the UV curing paint on the decorative strip is cured, the conveyor motor 4 drives the chain 5 to rotate again, and the painted decorative strip continues to move. After the decorative strip comes out of the protective cover 13, it can be removed. This device can achieve rapid painting of decorative strips, and the paint surface is quickly cured by high-intensity UV light after painting. There is no need to worry about damaging the paint surface when removing the decorative strip. Example

[0013] This embodiment discloses a car trim spraying device. Based on the structure and principle of Embodiment 1, this embodiment also has a fan 16 evenly fixed on the protective cover 13 on one side of the dark blue LED tube 14. The fan 16 draws out the hot air inside the protective cover 13, realizing airflow inside the protective cover 13 and preventing heat accumulation that could damage the dark blue LED tube 14. Example

[0014] This embodiment discloses an automotive trim strip painting device. Based on the structure and principle of Embodiment 1 or Embodiment 2, this embodiment further includes a baffle 15 fixed on the frame 1 below the protective cover 13. The baffle 15 is installed below the protective cover 13 to block light and prevent light pollution.
