Automatic Recognition Device and Method for Sheet Metal Bending Features Based on 3D Model

Abstract

This invention discloses an automatic sheet metal bending feature recognition device and method based on a 3D model in the field of sheet metal processing technology. The device includes a clamping and recognition component, a magnetic auxiliary component, and a magnetic stabilizing component. The clamping and recognition component, used to clamp and recognize sheet metal parts, includes a lifting base, an industrial camera mounted at the bottom of the lifting base, and a rotatable suction cup clamp. The magnetic auxiliary component is movably disposed below the lifting base and includes a magnetic component and a first electromagnet for attracting and releasing the magnetic component. When the magnetic component is lowered, it is inverted and placed on the upper end of a side plate so that the side plate can be attracted by the magnetic force. This invention, by setting the magnetic auxiliary component so that the magnetic component is attached to the top of the side plate, can be attracted by the magnetic force generated by the second electromagnet, thus providing a stable magnetic force to the side plate to eliminate wobbling. This allows for feature recognition of the second bend, determining its qualification, and eliminating the problem of inaccurate recognition caused by side plate wobbling.
