Description

Technical Field

[0001] This utility model relates to the field of automobile production and conveying, and specifically to a novel skid positioner. Background Technology

[0002] In the automobile production process, skids serve as the carriers for the car body-in-white, transporting and transferring the car body-in-white from different workstations. At some critical workstations, such as the body transfer station, the skids need to be precisely positioned to ensure the consistency of process actions and the success rate of transfer.

[0003] Conventional skid positioning uses two sets of detection switches. The skid first moves to the deceleration switch position and then to the stop switch position. This method cannot achieve precise positioning of the skid. Different vehicle models have different weights, and the stopping position of the skid may also change, thus making precise positioning of the skid impossible.

[0004] At present, a novel skid positioner is proposed to solve the problem of low skid positioning accuracy mentioned in the background art. Utility Model Content
