Magnet sorting device

Abstract

The invention discloses a magnet sorting device, which comprises a rack, a conveying track, a magnet detection probe, a camera, a data processor, a control circuit and a sorting device, wherein the conveying track is arranged on the rack, and the conveying track is connected with a motor and driven to rotate by the motor; laser detection heads are arranged above the rack; the magnet sorting device also comprises a first laser detection head and a second laser detection head which are symmetrically fixed on two sides of the conveying track; the magnet detection probe, the control circuit, the first laser detection head and the second laser detection head are connected with the data processor respectively; and the sorting device is connected with the control circuit. The projection size of magnets in the X-Y plane is measured through the camera, the height of the magnets is measured by the laser detection heads, and unqualified product is removed through the sorting device, so one-time measurement of three-dimensional size and sorting of the magnets are realized.

Description

Technical field [0001] The invention relates to a sorting device, in particular to a magnet sorting device. Background technique [0002] Rare earth permanent magnets are indispensable functional materials in modern industry. In the production of rare earth permanent magnets, the measurement of dimensional parameters such as the inner and outer diameters and height of the rare earth permanent magnets is a work that must be carried out before the magnets are packed and shipped. Due to the large number of magnets, accurate measurement of the size of magnets has always been a technical problem that plagued the industry. In actual production, the method of manual sampling of magnets is implemented. As long as the results of the sampling are within a reasonable range, the batch of magnets is considered qualified. This method has obvious drawbacks. First, manual methods are prone to errors. In addition, due to the sampling method, unqualified magnets may be missed. In recent years, ...
