Description

Technical Field

[0001] The utility model relates to a magnetization detection device after magnetization. Background Art

[0002] A magnet is a natural or artificial magnetic material that can generate a magnetic field. Artificial magnetic materials, such as neodymium iron boron magnets, have been widely used in electronics, automobiles, energy, machinery, medical treatment, aerospace and other fields because of their good magnetic properties and mechanical characteristics. However, artificial magnetic materials are not magnetic during the production process, and do not have the mutual repulsion and attraction characteristics of magnets. They can only be magnetic after undergoing the magnetization process. It is necessary to apply a magnetic field to the magnet to be magnetized through a magnetization tooling to make it magnetic. After magnetization, magnetization detection is required. The existing magnetization detection usually uses manual detection of magnetization one by one. Manual detection is not easy to adapt to the detection rhythm and is prone to errors, which reduces the overall detection efficiency. Utility Model Content

[0022] A limit plate 32 is provided at the bottom of the material trough 31 to support the magnet block 4. One side of the limit plate 32 is hinged to the bracket 35 through a pin shaft 33. The bracket 35 is fixed to the bottom of the positioning seat 3. A torsion spring 34 is installed on the pin shaft 33 and between the limit plate 32 and the bracket 35 (see Figure 3 , Figure 5 ), the limiting plates 32 are arranged in pairs, and the distance between the relatively arranged limiting plates 32 is greater than the outer diameter of the push block 8.

[0023] The device adopts a mechanical structure to replace manual operation. After the positioning seat with a built-in magnet block is magnetized at the magnetizing mechanism, it is moved as a whole into the positioning slot of the conveying turntable. The magnetic detection of the magnet block is automatically completed in cooperation with the magnetic detector, and the unqualified products are removed by using a push block, which effectively improves work efficiency.

The limiting plate flips with the pin as the center, and an opening is formed at the bottom of the material trough (see Figure 6 ), the magnet block falls from the bottom of the trough to the guide plate and slides out, then the push block moves up and resets, and the limit plate uses the elastic memory of the torsion spring to reset, and then the next magnet block is detected; when the magnet blocks on the positioning seat are detected in turn, the conveyor turntable drives the positioning seat to rotate to the unloading station, and the positioning seat can be taken out as a whole.
