[0001] This invention relates to coating processing, particularly to the field of dust removal technology before coating, specifically to a cleaning device for dust removal before coating and its usage method. Background Technology

[0002] Coating is a technique that deposits a thin film on the surface of a substrate to impart special properties to it. Dust removal before coating is a key pretreatment process, which aims to thoroughly remove micro-dust, oil stains and electrostatic adsorption substances from the surface of the substrate.

[0021] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, the specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0022] Many specific details are set forth in the following description in order to provide a full understanding of the invention. However, the invention may also be practiced in other ways different from those described herein, and those skilled in the art can make similar extensions without departing from the spirit of the invention. Therefore, the invention is not limited to the specific embodiments disclosed below.

[0023] Secondly, the term "one embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that is mutually exclusive with other embodiments.

[0024] Secondly, the present invention is described in detail with reference to the schematic diagrams. When detailing the embodiments of the present invention, for ease of explanation, the cross-sectional views illustrating the device structure may be partially enlarged, not according to the usual scale. Furthermore, the schematic diagrams are merely examples and should not limit the scope of protection of the present invention. In addition, actual fabrication should include three-dimensional spatial dimensions of length, width, and depth.

[0025] Example 1 Reference Figure 1-6 In the first embodiment of the present invention, a support device 1 is provided, including a control panel 101, a support table 102 and a support frame 103. The surface of the control panel 101 is fixedly connected to the side of the support table 102, and the surface of the support table 102 is fixedly connected to the lower end of the support frame 103. A dust suction device 2 is provided on the support table 102, and a wiping mechanism 3 is provided on the dust suction device 2. The dust suction device 2 is used to remove dust from the surface of the workpiece, and the wiping mechanism 3 is used to wipe the surface of the workpiece.

[0026] Specifically, the carrier device 1 effectively solves the problem that traditional cleaning equipment cannot adapt to workpieces of different thicknesses and has dispersed operation. Through the control panel 101, the carrier table 102 and the carrier frame 103, a stable working platform is constructed, which combines the dust removal and wiping cleaning mechanism to realize the process from dust removal to wiping. The spacing of the cleaning components can be adjusted according to the thickness of the workpiece, ensuring the versatility of the cleaning process and improving the efficiency of workpiece treatment before coating and the finished product qualification rate.

[0027] Furthermore, the workpiece is first placed on the support table 102, and the dust on the surface of the workpiece is removed by the dust suction device 2. The surface of the workpiece is wiped by the wiping mechanism 3. Then, the hydraulic pump 301 and hydraulic cylinder 302 are started to adjust the height of the wiping roller 304 and the dust collector 202 according to the thickness of the workpiece to adapt to the cleaning work of different workpieces.

[0028] Example 2 In a second embodiment of the present invention, a vacuuming device 2 is provided, comprising an ion fan 201, a vacuum cleaner 202, a vacuum pump 203, and a vacuum box 204. The vacuum cleaner 202 is disposed on the side of the ion fan 201. The surface of the vacuum pump 203 is fixedly connected to the surface of the vacuum box 204. The upper end of the vacuum box 204 is fixedly connected to the lower end of the support table 102. The surface of the vacuum cleaner 202 and the vacuum box 204 are fixedly connected through a flexible hose.

[0029] Specifically, this device effectively solves the problem of reduced coating quality and secondary dust pollution caused by electrostatic adsorption of dust on the workpiece surface. By neutralizing static electricity through the ion fan 201 and blocking dust adhesion at the source, combined with the synergistic effect of airflow blowing and negative pressure dust suction, the particle peeling and collection are achieved, ensuring the ultimate cleanliness of the surface before coating. It also seals the dust in the dust collection box 204, greatly improving the working environment and reducing the difficulty of subsequent cleaning.

[0030] Furthermore, the ion fan 201 generates high-pressure ion wind to neutralize the static electricity on the workpiece surface and prevent dust adsorption. At the same time, the strong airflow blows away surface particles. In conjunction with the activated vacuum cleaner 202 and vacuum pump 203, the dust is sucked into the vacuum box 204 through the hose, realizing surface dust removal before coating. In addition, the dust is concentrated in the vacuum box 204 for easy cleaning by staff, avoiding pollution of the working environment.

[0031] Example 3 The third embodiment of the present invention provides a wiping mechanism 3 including a hydraulic pump 301, a hydraulic cylinder 302, a moving plate 303, a wiping roller 304, a telescopic rod 305, a spring 306, and a cleaning brush 307. The hydraulic pump 301 is disposed on the upper end of the support frame 103. The lower end of the hydraulic cylinder 302 is fixedly connected to the upper end of the moving plate 303. The inner walls of both ends of the moving plate 303 are rotatably connected to the two ends of the wiping roller 304. The spring 306 is sleeved on the surface of the telescopic rod 305. The inner wall of the wiping roller 304 is slidably connected to the surface of the cleaning brush 307. A mating mechanism 4 is provided on the surface of the wiping roller 304. The mating mechanism 4 includes a servo motor 401, a sliding rod 402, a sliding sleeve 403, a bevel gear set 404, and a conveying roller 405. The output end of the servo motor 401 is fixedly connected to the upper end of the sliding rod 402. The surface of the sliding rod 402 slides against the inner wall of the sliding sleeve 403 through a sliding groove. The sliding sleeve 403 is fixedly connected to the inner wall of the bevel gear set 404. The output end of the bevel gear set 404 is fixedly connected to the surface of the conveying roller 405. The lower end of the hydraulic pump 301 is fixedly connected to the upper end of the support frame 103. The upper end of the hydraulic cylinder 302 is fixedly connected to the inner wall of the support frame 103. The surface of the moving plate 303 is slidably connected to the inner wall of the support frame 103 through a sliding groove. The two ends of the moving plate 303 are fixedly connected to the surfaces of the ion fan 201 and the vacuum cleaner 202, respectively. The two ends of the telescopic rod 305 are fixedly connected to the surface of the cleaning brush 307 and the inner wall of the wiping roller 304, respectively. The surface of the servo motor 401 is fixedly connected to the surface of the support frame 103. The output end of the bevel gear set 404 is fixedly connected to the surface of the wiping roller 304. The lower end of the sliding rod 402 is fixedly connected to the input end of the bevel gear set 404. The surface of the conveying roller 405 is rotatably connected to the inner wall of the support table 102.

[0032] Specifically, this mechanism effectively solves the problems of traditional cleaning methods that easily damage the surface of workpieces and are difficult to adapt to different thicknesses. By driving the bevel gear set 404 with the servo motor 401, synchronous linkage between conveying guidance and wiping cleaning is achieved. The flexible structure composed of the telescopic rod 305 and the spring 306 can not only powerfully remove stubborn particles, but also avoid hard scratches on the workpiece. In addition, the hydraulic pump 301 and the hydraulic cylinder 302 drive the moving plate 303 and related components to lift and lower as a whole, flexibly adjusting the cleaning distance to ensure that the best contact state is maintained for workpieces of different thicknesses, thereby improving the adaptability and safety of cleaning.

[0033] Furthermore, the bevel gear set 404 consists of nine bevel gears. When the servo motor 401 is started, the sliding rod 402 at its output end rotates, which drives the conveying roller 405 on the inner wall of the support table 102 to rotate through the bevel gear set 404, providing guiding force for the smooth movement of the workpiece. When the sliding rod 402 rotates, its surface sliding sleeve 403 moves in coordination with the slide groove, driving the bevel gear set 404 to drive the wiping roller 304 to work, initially wiping the surface of the workpiece. For stubborn particles, the telescopic rod 305 on the inner wall of the wiping roller 304 drives the microfiber brush or sponge roller to gently clean. The spring 306 ensures that the cleaning force is moderate and avoids damage to the workpiece. It can also be adjusted according to the thickness of the workpiece: starting the hydraulic pump 301 drives the hydraulic cylinder 302 to extend and retract, driving the moving plate 303 and the wiping roller 304 to slide along the slide groove. The ion fan 201 and the vacuum cleaner 202 adjust their positions synchronously to adapt to the cleaning needs of workpieces of different specifications and ensure a smooth process.

[0034] Working principle: First, the ion fan 201 generates high-pressure ion air, effectively neutralizing the static electricity on the workpiece surface and preventing dust from re-adhering at the source. Simultaneously, the strong airflow blows away surface particles. Combined with the activated vacuum cleaner 202 and vacuum pump 203, the blown-off dust is quickly sucked into the vacuum box 204 through a hose, achieving surface dust removal before coating. The dust being sucked into the vacuum box 204 also facilitates subsequent centralized cleaning by staff, preventing dust from spreading and polluting the working environment. Next, the servo motor 401 is activated, and the sliding rod 402 fixed at its output end rotates accordingly. The lower end of the moving rod 402 drives the conveying rollers 405 installed in the inner walls of both ends of the bearing table 102 to rotate through the meshing transmission of the bevel gear set 404, providing guiding force for the smooth movement of the workpiece. While the sliding rod 402 rotates, the sliding sleeve 403 fitted on its surface moves in coordination through the sliding groove. When the hydraulic pump 301 and hydraulic cylinder 302 drive the movement, the sliding sleeve 403 can move synchronously on the surface of the sliding rod 402, thus ensuring a continuous power supply. The wiping roller 304 can slide within the sliding grooves on both sides of the bearing frame 103, or it can slide within the grooves provided for the wiping roller 304. The rotation of 04 provides support, which in turn drives the bevel gear set 404 at the lower end of the sliding sleeve 403 on its surface to mesh via the sliding rod 402, ultimately driving the wiping roller 304 to start working and prepare for cleaning. As the wiping roller 304 rotates, the surface of the workpiece is initially wiped. For stubborn particles with strong adhesion, the telescopic rod 305 fixed to the inner wall of the wiping roller 304 drives the microfiber brush or sponge roller to perform soft contact cleaning. The spring 306 ensures that the cleaning force is moderate and avoids damage to the workpiece. The front end of the vacuum cleaner 202 also contacts the surface of the cleaning brush 307, and the cleaning... When the cleaning brush 307 rotates to the corresponding position of the vacuum cleaner 202, the vacuum cleaner 202 will absorb the dust adhering to the surface of the cleaning brush 307, ensuring that the cleaning brush 307 is always in a relatively dust-free state. In addition, it can be flexibly adjusted according to the thickness of the workpiece. During the dust removal work, the hydraulic cylinder 302 can be extended and retracted by starting the hydraulic pump 301, which will drive the moving plate 303 and the wiping roller 304 to slide along the slide groove. The ion fan 201 and the vacuum cleaner 202 will also adjust their positions synchronously, thereby adapting to the cleaning needs of workpieces of different sizes and ensuring that the whole process is smooth.

[0035] In summary, by combining the electrostatic neutralization of the ion blower with the airflow purging, the guiding transmission of the conveyor roller, and the flexible cleaning of the wiping roller, and supplemented by the hydraulic pump to adjust the spacing of the wiping mechanism, a cleaning process is achieved that goes from preventing secondary dust adsorption and collecting particles to deeply removing stubborn particles. This improves the cleanliness of the workpiece before coating and the quality of the working environment while ensuring that the workpiece surface remains undamaged.

At the same time, the telescopic rod (305) fixed on the inner wall of the wiping roller (304) is fixed to the cleaning brush (307). For particles with strong adhesion, a microfiber brush or sponge roller may be equipped for physical contact cleaning. Combined with the telescopic rod (305) and the spring (306) sleeved on the surface, flexible cleaning is achieved, avoiding damage to the workpiece. To avoid damage to the workpiece and affect subsequent work, the distance of the cleaning roller can be adjusted according to the thickness of the workpiece. By starting the hydraulic pump (301), the hydraulic cylinder (302) is driven to extend and retract. The hydraulic cylinder (302) drives the moving plate (303) and the wiping roller (304) to slide along the groove on the inner wall of the support frame (103). As the moving plate (303) moves, the ion fan (201) and the vacuum cleaner (202) can synchronously follow the wiping roller (304) through the distance, which is convenient for cleaning different workpieces.
