Background
In the current screening operation, the spherical-like objects (such as dry spheres) need to be screened. The existing screening device is mainly used for screening through a vibrating screen or manual screening. Screens are indispensable, whether by machine or manual screening. Typically, the screen is provided with a plurality of holes, the diameters of the holes are slightly smaller than the diameters of the spherical objects, so that unqualified objects smaller than the diameters of the holes can pass through the holes, and spherical objects with qualified diameters can be left on the screen. Of course, this is just an ideal screening process.
In practice, we often encounter objects in the form of rice grains (i.e. objects with a longer diameter than the diameter of the mesh and a shorter diameter than the diameter of the mesh) or other non-circular objects (such as long rod-shaped objects) with at least one part of the object having a larger diameter or length than the diameter of the mesh), which cannot pass through the mesh of the mesh and remain on the mesh, and this requires secondary screening (usually also manual screening), which is slow in operation or prone to false positives.
