AI Technical Summary
In existing technologies, the hinge Y/Rx cannot be adjusted according to the overall vehicle dimensions during automatic door assembly, resulting in the door and body gap not being optimally matched, causing assembly errors.
Design an E-SHIM mechanism, including a lifting mechanism, a connecting device, and a hinge placement platform. Driven by a combination of servo motors and cylinders, the hinge can be actively adjusted in the Y direction. It works in conjunction with the Bestfit vision system for closed-loop correction and uses magnets and limit blocks to ensure reliable clamping and in-situ detection of the hinge.
Significantly reducing the gap between the door and the body surface improves assembly precision. The two-stage drive of servo motor and cylinder enables rapid response and high-precision positioning, ensuring the reliability and accuracy of hinge installation.
