[0002] Currently, in automated production and assembly, manual gluing is being replaced by automated gluing using robotic arms for various reasons, including safety, efficiency, convenience, and increased automation. Robotic arms are complex systems with high precision, multiple inputs and outputs, high nonlinearity, and strong coupling. Due to their unique operational flexibility, they are widely used in industrial assembly, safety, and explosion-proofing. During use, robotic arms work in conjunction with mobile carts to apply glue at various locations.

[0003] However, in actual use, different effects will occur due to the different gluing environments. When used in a dusty workshop, in order to ensure the firmness of the glue adhesion, the dust at the glue coating area will be blown clean, which will cause dust to fly. Some dust will fall on the slide rails of the robotic arm's walking trolley. After long-term use, the dust will gradually settle on the slide rails, affecting the trolley's movement, and will also cause friction and scratches on the slide rails, affecting the accuracy of the trolley's displacement.

The two cleaning assemblies 5 are fixed on the left and right sides of the movable assembly 3. When the movable assembly 3 moves, the slide rail 23 is cleaned first. After the dust on the slide rail 23 is cleaned, the movable assembly 3 cooperates with the slider 26 to walk on the slide rail 23 to prevent dust from accumulating on the slide rail 23 and scratching the slide rail 23. The front end of the fixed plate 31 is fixed with a motor 32, and the output end of the motor 32 is fixed with a bevel gear 33. The motor 32 is meshed with the bevel rack 21 through the bevel gear 33. The manipulator 4 is fixed on the lower side of the rear end of the fixed plate 31, and the bevel gear 33 is meshed with the bevel rack 21. When the motor 32 rotates forward and reverse, due to the meshing effect of the bevel gear 33 and the bevel rack 21, the movable assembly 3 drives the manipulator 4 to move back and forth. The manipulator 4 is an existing device and will not be described in detail here.

[0026] See also Figure 2 、 Figure 4 、 Figure 5 and Figure 6 The cleaning assembly 5 includes two side plates 51 symmetrically arranged front and back, and two symmetrical dust collecting plates 52 are fixed inside the side plates 51. The lower ends of the dust collecting plates 52 are rotatably connected to cleaning rollers 53. The two cleaning rollers 53 are driven by gears to achieve the effect of mutual reverse rotation. The upper ends of the side plates 51 are detachably connected to dust covers 54. The upper ends of the spur racks 22 are provided with two symmetrical contact sensors. The electromagnets 57 on the side plates 51 are connected to an external power supply. By providing contact sensors on the spur racks 22, the electromagnets 57 are controlled by the contact sensors to make the limit frame 56 slide in the slideway 511. When the movable component 3 moves back and forth, it can ensure that the two cleaning rollers 53 rotate relative to each other, showing an upward clamping effect, clamping the dust on the slide rail 23 upward so that it adheres to the brush 532, and scraping the dust on the brush 532 through the comb teeth on the dust collecting plate 52, so that the dust is collected between the dust collecting plate 52 and the dust cover 54. A switching wheel 55 is provided on the side plate 51 on the rear side, and the switching wheel 55 is connected to the cleaning roller 53 for transmission. The switching wheel 55 is engaged with the spur rack 22 for transmission, and the switching wheel 55 is engaged with the spur rack 22 to drive the cleaning component 5 to clean, without the need for additional power source, saving cost investment.

[0027] See also Figure 3 、 Figure 4 、 Figure 5 and Figure 6The cleaning roller 53 is in an inverted U shape. The cleaning roller 53 is set to a U shape so that the cleaning roller 53 can also clean the side of the slide rail 23 to ensure the cleanliness of the slide rail 23. One end of the cleaning roller 53 is rotatably connected to the side plate 51, and the other end of the cleaning roller 53 is fixed with a driven wheel 533. The switching wheel 55 is meshed with the driven wheel 533 fixed on the cleaning roller 53 for transmission. The switching wheel 55 is engaged with the spur rack 22 to rotate the switching wheel 55 itself. The switching wheel 55 is meshed with the driven wheel 533. The driven wheel 533 rotates, and the driven wheel 533 is fixed to the wire rope 531, thereby driving the wire rope 531 to rotate, so that the brush 532 cleans the dust on the slide rail 23. The cleaning roller 53 includes a wire rope 531 and a brush 532. The brush 532 is twisted and fixed in the wire rope 531 when it is twisted and produced. When the wire rope 531 is produced, the brush 532 is directly placed in it for twisting to form the cleaning roller 53, ensuring the firmness of the connection between the wire rope 531 and the brush 532, and preventing the brush 532 from being twisted and rolled. 32 falls off, the outer side of the wire rope 531 is rotatably connected to a plurality of spaced fixed rings, which are fixed on the dust collecting plate 52. The fixed ring limits the cleaning roller 53, making the cleaning roller 53 U-shaped, which is convenient for cleaning the slide rail 23. The dust collecting plate 52 is close to the cleaning roller 53 and is provided with comb teeth for scraping dust off the cleaning roller 53.

The moving direction of the moving component 3 is controlled by the forward and reverse rotation of the motor 32.

[0030] Then, while the moving assembly 3 moves, the cleaning assembly 5 cleans the dust on the slide rail 23. When the moving assembly 3 moves to the right, the switching wheel 55 engages with the spur rack 22, and the switching wheel 55 engages with the driven wheel 533. The driven wheel 533 is fixed to the wire rope 531, which drives the wire rope 531 to rotate, so that the brush 532 cleans the dust on the slide rail 23. The cleaning roller 53 rotates relatively, cleans and picks up the dust on the slide rail 23, so that the dust adheres to the brush 532 and cleans. After the roller 53 rotates, the brush 532 passes through the comb teeth of the dust collecting plate 52, so that the dust on the brush 532 is scraped off and stored between the dust collecting plate 52 and the dust cover 54. When the cleaning component 5 moves to the right end face and contacts the contact sensor at the right end, the electromagnet 57 on the right side is powered off, and the electromagnet 57 on the left side is powered on to adsorb and fix the switching wheel 55 on the left side, so that the switching wheel 55 and the driven wheel 533 on the left side are driven to ensure that the rotation direction of the two cleaning rollers 53 remains unchanged when moving to the left end;

[0031] Finally, the comb teeth on the dust collecting plate 52 scrape off the dust on the brush 532. The dust on the brush 532 is scraped off and stored between the dust collecting plate 52 and the dust cover 54. After use, the dust cover 54 is removed and the dust can be removed.
