[0002] In the field of automobile manufacturing, hard tops (such as metal stamping roofs, composite material roofs, etc.), as important components of the vehicle body structure, their surface cleanliness directly affects the painting quality, sealing performance, and overall vehicle aesthetics. During the production process of automobile hard tops, they need to go through multiple processes such as stamping, welding, grinding, and pre-treatment of painting. During this period, pollutants such as metal dust, welding slag debris, and grinding particles will be generated. If not thoroughly removed, the residual dust will cause defects such as pinholes and orange peel in the paint layer, and the debris in the welding area may even cause the sealant bonding to fail, thereby affecting the waterproofness and structural strength of the roof.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0023] The present invention will be further described in detail below with reference to the accompanying drawings.

[0024] Among them, the same parts are denoted by the same reference numerals. It should be noted that the terms "front", "rear", "left", "right", "upper" and "lower" used in the following description refer to the directions in the drawings, and the terms "bottom surface" and "top surface", "inner" and "outer" refer to the directions towards or away from the geometric center of a specific component, respectively.

[0025] As shown in the figure, a dust removal and cleaning device for special-shaped plates includes a cleaning chamber 1. Upper guide rails 2 and lower guide rails 3 are provided at both the bottom and the top of the cleaning chamber 1. An upper fixed bracket 4 and a lower fixed bracket 5 are respectively slidably connected to the upper guide rail 2 and the lower guide rail 3. It also includes a driving assembly for driving the upper fixed bracket 4 and the lower fixed bracket 4. On both sides of the upper guide rail 2 and the lower guide rail 3 inside the cleaning chamber 1, two cleaning rollers 6 are provided. Both ends of the cleaning rollers 6 are rotatably connected to the top and the bottom of the cleaning chamber 1 through bearing seats. It also includes a driving member 7 for driving the cleaning rollers 6;

[0026] Place the workpiece between the upper fixed bracket 4 and the lower fixed bracket 5, send it into the working area of the cleaning rollers 6 through the driving assembly, and drive the cleaning rollers 6 to clean the workpiece through the driving member 7. After cleaning and dust removal of the workpiece, drive the upper fixed bracket 4 and the lower fixed bracket 5 to reset through the driving assembly, so as to move away from the cleaning rollers 6. Finally, take out the cleaned workpiece from the cleaning chamber 1, effectively improving the cleaning efficiency and effect of the workpiece and reducing the manual cleaning cost.

[0027] The driving assembly includes a first cable 8. One end of the first cable 8 is fixedly connected to the end of the upper fixed bracket 4 away from the cleaning rollers 6. A first guide wheel 9 is provided on the inner wall of one side of the cleaning chamber 1 away from the cleaning rollers 6. The lower guide rail 3 is hollow, and first through grooves are provided at both ends of its top for the first cable 8 to pass through. A second guide wheel 10 is provided on the inner wall of one side of the cleaning chamber 1 below the first guide wheel 9. A third guide wheel 11 is provided on the other side wall of the cleaning chamber 1. Both the second guide wheel 10 and the third guide wheel 11 are located inside the lower guide rail 3. A fourth guide wheel 12 is provided on the inner wall of one side of the cleaning chamber 1 above the third guide wheel 11. After the other end of the first cable 8 bypasses the first guide wheel 9, the second guide wheel 10, the third guide wheel 11 and the fourth guide wheel 12, it is fixedly connected to the end of the lower fixed bracket 5 facing the cleaning rollers 6. It also includes a cylinder 13 for driving the upper fixed bracket 4. The cylinder 13 is horizontally arranged and fixedly connected to one side of the upper guide rail 2, and the end of its piston rod is fixedly connected to the upper fixed bracket 4.

[0028] After placing the workpiece on the upper fixed bracket 4 and the lower fixed bracket 5, the cylinder 13 pushes the upper fixed bracket 4 to move towards the cleaning rollers 6, and under the action of the first cable 8, simultaneously pulls the lower fixed bracket 5 and the upper fixed bracket 4 to move towards the cleaning rollers 6 synchronously, so as to drive the workpiece to smoothly enter the cleaning rollers 6 for cleaning and dust removal work.

[0029] The driving assembly further includes a second pulling rope 14, one end of which is fixedly connected to one end of the upper fixing bracket 4 facing the cleaning roller 6. A fifth guiding wheel 15 is arranged on the inner wall of the cleaning cabin 1 close to the cleaning roller 6. A sixth guiding wheel 16 is arranged above the fifth guiding wheel 15. A seventh guiding wheel 17 is arranged on the inner wall of the other side of the cleaning cabin 1. An eighth guiding wheel 18 is also arranged below the seventh guiding wheel 17. Both ends of the upper guiding rail 2 are provided with second through grooves penetrating through its upper and lower surfaces for the second pulling rope 14 to pass through. After the other end of the second pulling rope 14 bypasses the fifth guiding wheel 15, the sixth guiding wheel 16, the seventh guiding wheel 17 and the eighth guiding wheel 18, it is fixedly connected to one end of the lower fixing bracket 5 away from the cleaning roller 6.

[0030] After the cleaning is completed, the air cylinder 13 drives the upper fixing bracket 4 to reset. Under the action of the second pulling rope 14, the lower fixing bracket 5 and the upper fixing bracket 4 are simultaneously pulled to move away from the cleaning roller 6 synchronously, so as to drive the workpiece to leave the working area of the cleaning roller 6. By arranging the first pulling rope 8 and the second pulling rope 14, while driving the upper fixing bracket 4 and the lower fixing bracket 5 to move synchronously, the separated design of the upper fixing bracket 4 and the lower fixing bracket 5 enables them to be installed and replaced separately, reducing the processing and installation costs.

[0031] An air inlet is provided at the top of the cleaning cabin 1, and an air outlet is provided on one side thereof. A filter screen 19 is arranged in the air inlet, and an exhaust duct 20 is arranged at the air outlet. When the cleaning work is carried out, by connecting an exhaust and dust removal device (not shown in the figure) at the exhaust duct 20, the dust in the cleaning cabin 1 can be quickly cleaned, and under the action of the filter screen 19, the air entering the cleaning cabin 1 can be filtered. A sliding door 21 is arranged on one side of the cleaning cabin 1. When the cleaning is carried out, by closing the sliding door 21, the sealing performance of the cleaning cabin 1 can be ensured, further improving the cleaning and dust removal effect on the workpiece.

[0032] Positioning clamps 22 are arranged at both ends on one side of the upper fixing bracket 4. After the workpiece is placed on the lower fixing bracket 5, the top of the workpiece is clamped and positioned by the positioning frame. The positioning clamp 22 is a prior art, and its structure will not be described in detail in this embodiment.

[0033] A plurality of flexible cleaning strips (not shown in the figure) are arranged on the surface of the cleaning roller 6. The flexible cleaning strips are made of silica gel material. A steam generator 23 is also arranged in the cleaning cabin 1. When the driving member 7 drives the cleaning roller 6 to rotate, the flexible cleaning strips are driven to swing, so as to effectively clean and remove dust on the surface of the workpiece. And through the water vapor generated by the steam generator 23, the humidity in the cleaning cabin 1 is increased, which can soften the flexible cleaning strips and reduce the generation of static electricity, thereby reducing the influence of static electricity on the dust removal effect of the workpiece.

[0034] The driving member 7 is a bidirectional variable-frequency motor, which can adjust the rotation direction and speed of the cleaning roller 6 according to the shape of the plate, thereby further improving the cleaning effect on the workpiece.

[0035] The specific embodiments are only explanations of the present invention and are not limitations thereof. After reading this specification, those skilled in the art can make modifications to this embodiment without creative contributions as needed, but as long as they are within the scope of the claims of the present invention, they are protected by the patent law.
