[0033] The telescopic assembly includes a bidirectional electric telescopic rod 31, the two ends of which are fixedly connected to the outer walls of the two groups of mounting seats 7 respectively. By starting the bidirectional electric telescopic rod 31, the two groups of mounting seats 7 are driven to move synchronously, thereby adjusting the distance between the two groups of mounting seats 7.

[0034] The moving assembly includes a third motor 32, a telescopic rotating shaft 33, a gear 34, a rack 35 and a limiting slot 36. The telescopic rotating shaft 33 is rotatably installed between the two groups of the mounting seats 7. The telescopic rotating shaft 33 is driven by the third motor 32. A gear 34 is fixed on the telescopic rotating shaft 33 inside the mounting seat 7. A rack 35 is provided on the top of the third crossbeam 8, and the gear 34 is meshed with the rack 35. A limiting slot 36 is provided on the side wall of the third crossbeam 8. The bottom of the mounting seat 7 is slidably connected to the limiting slot 36. By starting the third motor 32, the third motor 32 drives the telescopic rotating shaft 33 to rotate, thereby driving the gear 34 to rotate.

By starting the second electric telescopic rod 42, the angle of the dust collection box 41 can be adjusted, thereby preventing the dust collection box 41 from affecting the adsorption of the plate.

[0037] When the bridge conveying robot of the wheel cover production line is in use, the spacing of the fixing member 11 is adjusted by the second adjustment component and the bidirectional electric telescopic rod 31. After the position adjustment is completed, the angle of the dust box 41 is adjusted by the second electric telescopic rod 42, and then the dust box 41 is driven to move by the horizontal moving slide 2 and the vertical moving slide 3, so as to vacuum the surface of the plate. After that, the dust box 41 and the fixing member 11 are reset. At this time, by starting the first electric telescopic rod 19 and pushing the first motor 20 downward, the mounting plate 21 and the fixing plate 22 are synchronously moved downward. At this time, the flexible pad 18 extends from the conical through groove 17, so that the flexible pad 18 is unfolded. At the same time, the limit rod 23 rotates, causing the reset assembly to drive the adsorption plate 15 to move upward, thereby storing the adsorption plate 15. At this time, the first motor 20 is started to drive the flexible pad 18 to rotate, so that the adsorption point of the plate can be cleaned. Then the first electric telescopic rod 19 is started again, and the first electric telescopic rod 19 pulls the first motor 20 to move upward, thereby driving the mounting plate 21 and the fixed plate 22 to move upward synchronously. At this time, the center of the flexible pad 18 moves upward synchronously, so that the flexible pad 18 is squeezed into a cone and stored in the conical slot. At the same time, the limit rod 23 rotates, and one end of the limit rod 23 presses the reset assembly, causing the adsorption plate 15 to extend, thereby performing the adsorption work of the plate.
