[0003] In the automobile manufacturing process, the roller bed elevator is mainly used for the transportation and storage and transportation conversion of automobile workpieces. It can convert automobile workpieces from ground processing to aerial storage and transportation. However, in the process of conveying automobile workpieces by the existing roller bed elevator, since the automobile workpieces still have dust and particles on their surface during transportation, this causes the dust and particles on the surface of the automobile workpieces to fall on the conveying rollers in the roller bed when they are conveyed on the roller bed, which can easily cause dust or particles to be adsorbed on the surface of the conveying rollers, and then get stuck between the two conveying rollers when the conveying rollers rotate. After getting stuck, the workpiece vibrates due to the inertia of transportation, which can easily cause the automobile workpiece to fall off the roller bed, posing a safety hazard.

When the lifting drive assembly 300 drives the rolling bed frame 200 to move upward, the limiting and fixing assembly 700 separates from the baffle 420, releasing the limit on the baffle 420. When the lifting drive assembly 300 drives the rolling bed frame 200 to move downward, the limiting and fixing assembly 700 abuts against the baffle 420, and limits and fixes the baffle 420.

[0049] Combination Figure 1-Figure 3In a roller bed lift of the present embodiment, when conveying an automobile workpiece, the side plate 410 is first pulled to drive the baffle plate 420 to move forward to a position, and then the electric conveying roller 210a is started to push the automobile workpiece to move toward the top of the roller bed frame 200, and the automobile workpiece pushes the baffle plate 420 and the side plate 410 to move toward the top of the roller bed frame 200, and the side plate 410 moves backward to drive the flushing component 500 to flush the surface of the automobile workpiece, and the dust and particles attached to the surface of the automobile are flushed down and fall on the bottom of the electric conveying roller 210a, and some particles fall through the gap between the electric conveying rollers 210a, and at the same time, the protection frame 400 moves backward to drive the cleaning component 600 to flush the electric conveying The surface of the roller 210a is cleaned, and some particles attached to the surface of the electric conveyor roller 210a are removed until the automobile workpiece pushes the baffle 420 and the side plate 410 to move back into place. At this time, the workpiece is started and located at the top of the roller frame 200, and the electric conveyor roller 210a stops rotating. The lifting drive assembly 300 is started to drive the roller frame 200 to move upward, and the limiting fixing assembly 700 is separated from the baffle 420 until the roller frame 200 pushes the automobile workpiece to move up into place. At this time, the electric conveyor roller 210a is started to push the automobile workpiece to continue to move back, and the automobile workpiece pushes the baffle 420 to flip open, and is separated from the top of the roller frame 200 as the electric conveyor roller 210a pushes.

Since the protrusion 720b abuts against the limit plate 420a, the limit block 720 limits the baffle plate 420. As the automobile workpiece abuts against the baffle plate 420, the automobile workpiece pushes the baffle plate 420 and the side plate 410 to move backward. When the side plate 410 moves backward, the first one-way rack 220 drives the first one-way gear 510a The first reciprocating threaded rod 510b-2 rotates, and then drives the first reciprocating threaded rod 510b-2 to rotate, pushing the piston 520b to reciprocate inside the fixed pipe 520a, and the water inside the water tank 530 is transported to the diversion pipe 540 and sprayed on the surface of the workpiece through the high-pressure nozzle 540a to wash the workpiece. At the same time, the second one-way rack 410a drives the second one-way gear 610 to rotate, and then drives the two moving plates 620 to reciprocate. The bristles 620a scrape the dust particles on the surface of the electric conveying roller 210a until the automobile workpiece pushes the baffle 420 and the side plate 410 to move backward. The motor 310 starts to drive the positive and negative threaded rod 310a to rotate, pushing the two first sliders 320 to approach each other and squeeze the connecting rod 340, and the two second sliders 330 to approach each other. The flat rack 330a drives the third gear 710a and the threaded rod 710c-2 to rotate, pushing the protrusion 720b to separate from the limit plate 420a, until the rolling bed 200 moves up to the position, and the motor 310 starts to drive the automobile workpiece to move backward, and the automobile workpiece pushes the baffle 420 to flip and The torsion spring 420b is squeezed until the automobile workpiece is separated from the top of the rolling bed 200. The torsion spring 420b pushes the baffle 420 to rebound and reset. The starting motor 310 drives the two second sliders 330 to move away from each other, and the rolling bed 200 descends. The flat rack 330a drives the third gear 710a and the threaded rod 710c-2 to reverse, pushing the limit block 720 to move backward, and the protrusion 720b abuts against the side wall of the limit plate 420a to limit and fix the baffle 420 until the rolling bed 200 descends into place, pulling the baffle 420 and the side plate 410 forward, waiting for the next conveying operation.
