Automatic tightening method for vehicle screws
By acquiring vehicle dynamic information and initial position information, the mobile platform is controlled to perform synchronous following motion. Visual sensors and actuators are used for screw hole positioning and dual closed-loop servo control, which solves the problem of real-time synchronous following and positioning of screw tightening on the vehicle assembly line, and achieves efficient and accurate screw tightening.

AI Technical Summary
Technical Problem
Existing technologies make it difficult to achieve real-time synchronous tracking and positioning tightening of vehicle chassis bolts on vehicle assembly lines, resulting in low efficiency and reliability of automated tightening.
Method used
By acquiring the dynamic and initial position information of the target vehicle, the mobile platform is controlled to follow the movement synchronously. Visual sensors and actuators are used to locate the screw holes, and the screw tightening is completed by combining dual closed-loop servo control.
Benefits of technology
It enables efficient and precise tightening of vehicle chassis bolts in dynamic environments, improving assembly efficiency and reliability while reducing reliance on manual operation.

Abstract
The invention discloses an automatic tightening method for vehicle screws, and relates to the technical field of automatic control, and the method comprises the steps: obtaining the dynamic information of a target vehicle and the initial position information of all target screw holes; based on the dynamic information, the mobile platform is controlled to perform synchronous following motion, so that the mobile platform and the target vehicle keep a preset relative position relationship; based on the initial position information, an execution mechanism installed on the mobile platform is controlled to position a preset target screw hole, the actual position of the preset target screw hole is obtained, and the preset target screw hole is determined from all the target screw holes based on a preset screening rule; determining target positions of all target screw holes based on the actual position and initial position information of the preset target screw holes; and the execution mechanism is controlled to move to target positions corresponding to all the target screw holes, and all the target screws are tightened.
