Description

Technical Field

[0001] The present invention mainly relates to the technical field of interior decoration treatment, and particularly relates to a flame treatment device for automobile interiors. Background Art

[0002] In the field of automobile manufacturing, the surface treatment quality of automobile interior parts has a crucial impact on the overall performance and aesthetics of products. With the continuous improvement of consumers' requirements for automobile quality, interior parts not only need to have good physical and mechanical properties, but also need to meet higher standards in aspects such as the adhesion and wear resistance of surface coatings. Flame treatment, as a process that can effectively improve the surface activity of materials and enhance the coating adhesion, has been widely used in the production of automobile interiors. Traditional automobile interior flame treatment devices often only have a single flame treatment function and do not perform pretreatment on the surface of interior parts. In the actual production process, during the forming and transportation of automobile interior parts, the surface will adhere to pollutants such as dust, impurities, oil stains, and mold release agent residues. The presence of these pollutants will hinder the full contact between the flame and the surface of the interior parts, resulting in a significant reduction in the flame treatment effect, unable to effectively activate surface molecules, making it difficult for the subsequent coating to adhere firmly, and prone to quality problems such as coating peeling and blistering. Some enterprises adopt the method of manually cleaning the surface of interior parts. However, this method is not only inefficient and difficult to meet the needs of large-scale production, but also the cleaning effect is greatly affected by human factors, and the cleaning quality is unstable. Even if some simple mechanical cleaning devices are used, there are also problems such as incomplete cleaning and difficulty in adapting to interior parts with different shapes and structures, and cannot provide ideal surface conditions for flame treatment.

[0022] The brush component 46 includes two symmetrically arranged mounting brackets 461, the mounting brackets 461 are arranged at the lower end of the installation disk 43, two rotating shafts 462 are rotatably installed between the two mounting brackets 461, a roller brush 463 is sleeved on the outer wall of the rotating shaft 462, and a reduction motor 464 is installed at one end of each of the two rotating shafts 462.

[0023] The high-pressure air gun component 5 includes a bracket two 51 fixed to the frame 1, a lifting cylinder two 52 is fixedly installed on the bracket two 51, an installation plate 53 is fixedly installed at the output end of the lifting cylinder two 52, a plurality of air gun bodies 54 are annularly and arrayedly installed at the lower end of the installation plate 53, and the air gun bodies 54 are connected to a high-pressure air source through air pipes 55.

[0024] The flame spray gun assembly 6 includes an X-axis movement module 61 fixed on the second bracket 51. A Y-axis movement module 62 is arranged at the output end of the X-axis movement module 61.

The bracket 64 is used to install the spray gun body 65.

[0025] Working principle: When the device starts, the chain conveyor 2 starts to operate driven by the motor. The interior parts to be processed are placed on the chain conveyor 2. When it is conveyed to the position of the clamping mechanism 3, the clamping cylinder 31 starts, pushing the clamping plate 33 to slide along the guide rod 34. The interior parts are firmly clamped by the symmetrically arranged clamping plates 33. The L-shaped angle iron 32 and the guide rod 34 ensure the smooth sliding of the clamping plate 33 and prevent the interior parts from shifting during the clamping process. The lifting cylinder 42 of the cleaning assembly 4 extends, driving the mounting plate 43 to move downward along the guide shaft 44 and the guide sleeve 45, making the brush assembly 46 close to the surface of the interior parts. Subsequently, two reduction motors 464 respectively drive the two rotating shafts 462 to rotate, and the brush rollers 463 sleeved on the rotating shafts 462 rotate accordingly. Through mechanical friction, the debris on the surface of the interior parts, especially the impurities in the gaps, grooves and other parts, are cleaned. After the cleaning is completed, the lifting cylinder 42 retracts, driving the brush assembly 46 to rise and reset. Then, the interior parts continue to be conveyed by the chain conveyor 2 to the lower part of the high-pressure air gun assembly 5. The lifting cylinder 52 extends, pushing the mounting plate 53 to descend, making the air gun body 54 close to the interior parts. At this time, the high-pressure air source supplies air to the air gun body 54 through the air pipe 55. The air gun body 54 sprays high-pressure gas, and uses the impact force of the high-speed air flow to blow away the light impurities such as dust and debris remaining on the surface of the interior parts, as well as the tiny particles remaining after the cleaning by the cleaning assembly 4. After the cleaning is completed, the lifting cylinder 52 retracts, and the mounting plate 53 drives the air gun body 54 to rise and reset.

[0026] Finally, the interior parts move to the lower part of the flame spray gun assembly 6. The X-axis movement module 61 and the Y-axis movement module 62 work together to move the spray gun body 65 to a suitable horizontal position. The rotary cylinder 63 adjusts the angle of the spray gun body 65 according to the shape of the interior parts. Subsequently, the gas and air are mixed and ignited in the spray gun body 65 to generate a high-temperature flame, and the surface of the interior parts is flame-treated to improve the surface activity. After the treatment is completed, each movement module and the rotary cylinder 63 reset, waiting for the next treatment.

[0027] The above-described embodiments merely represent certain implementation manners of the present invention. The description thereof is relatively specific and detailed, but it should not be construed as a limitation to the scope of the patent for the present invention.
