Three-dimensional scanner mark point with self-adsorbing suction cup

Abstract

The invention discloses a three-dimensional scanner mark point with a self-adsorbing suction cup. A mark point body and a self-adsorbing device are included; the self-adsorbing device comprises vacuumgas pumping holes, a suction cup base body, a suction cup bottom and a gas guiding flow channel; the suction cup base body and the suction cup bottom are of an integrally formed disk structure and are made from an elastic material, and a cavity is formed between the suction cup base body and the suction cup bottom; the center of the suction cup base body is of an arched structure, and the plurality of vacuum gas pumping holes are uniformly distributed in the arch face, and are externally connected with a vacuum pump; the centroid position of the arch face is connected with the mark point body; the suction cup bottom face is provided with the gas guiding flow channel, so that the cavity communicates with the outside atmosphere; and the vacuum pump is used for completely pumping out air inthe cavity and air between the suction cup bottom face and a scanned workpiece so that the three-dimensional scanner mark point with the self-adsorbing device can be adsorbed onto the scanned workpiece. The three-dimensional scanner mark point with the self-adsorbing suction cup is repeatedly utilized, and meets the scanning requirements of different material workpieces.

Description

technical field [0001] The invention relates to the technical field of three-dimensional scanning equipment, in particular to a marking point of a three-dimensional scanner with a self-adsorption suction cup. Background technique [0002] A 3D scanner is a scientific instrument used to detect and analyze the shape and appearance data of the real world or the environment, such as color, surface albedo, etc. Create digital models of actual objects in . The purpose of the 3D scanner is to create a point cloud of the geometric surface of the object. These points can be used to interpolate the surface shape of the object. If you need to obtain the surface color, you can paste the material map on the surface of the object, which is the so-called material mapping. The 3D scanner greatly improves work efficiency in digital modeling, especially when performing "reverse" design, it can automatically generate a digital model. [0003] The marking points of the 3D scanner are mainly a...

Problems solved by technology

[0004] At present, the marking points used in 3D scanners mainly include self-adhesive marking points and magnetic marking points. The self-adhesive marking points are one-time marking points, which waste resources and should not be removed from the surface of the workpiece after use; magnetic marking points Although the points can be reused, they can only be applied to the surface of steel workpieces, which has great limitations.
