Description

Technical Field

[0001] The utility model belongs to the technical field of magnetizers, in particular to a magnetizer for processing NdFeB permanent magnet steel. Background Art

[0002] The magnetizer is a device that can provide permanent magnetization. It is mainly composed of an electromagnet and additional magnetic poles, and uses plastic magnets, synchronous motors, etc. The working principle of the magnetizer is to first charge the capacitor with a DC high voltage, and then discharge it through a coil with extremely low resistance, so that a strong magnetic field is generated in the coil, which permanently magnetizes the hard magnetic material placed in the coil.

[0003] With the current market development and demand, there are higher and more stringent requirements on the production efficiency and quality level of NdFeB magnetic materials, especially in the subsequent magnetization stage of NdFeB magnetic materials used in mobile phone cameras. NdFeB magnetic materials are often easy to block the transportation track during magnetization, and manual operation is required to clear the blocked transportation track.

[0004] The utility model with announcement number CN220041510U discloses a special-shaped magnet magnetizer, including a base, a bracket is fixedly connected to the upper surface of one end of the base, a vibration plate is fixedly connected to the upper surface of the bracket, a track is fixedly connected to one side of the vibration plate, the track passes through and is fixedly connected to the magnetizer, a fixed seat is fixedly connected to the lower end of the magnetizer, an end of the fixed seat away from the magnetizer is fixedly connected to the base, and an anti-stuck mechanism is fixedly connected to the upper surface of the base.

[0005] In the process of implementing this application, it was found that the technology has the following problems: in the above patent document, a motor is used to drive the driving wheel to rotate, the driving wheel drives the driven wheel to rotate through a belt, the driven wheel drives the turntable to rotate, and the turntable drives the lever to rotate, so that the magnet in the track is pushed by the lever to squeeze it and avoid blockage of the track; however, in the document, the position of the turntable is fixed, and the special-shaped magnets transported in the track are often close to each other. When the position of the turntable is not between two adjacent special-shaped magnets, it is difficult to push and squeeze the special-shaped magnet from the end, and the driving force that can be applied from the upper surface of the special-shaped magnet is small, so the overall anti-blocking effect is poor.

[0006] For this purpose, a magnetizing machine for processing NdFeB permanent magnet steel is proposed. Utility Model Content

[0007] The purpose of the utility model is to provide a magnetizing machine for processing NdFeB permanent magnets in order to improve the anti-blocking effect of NdFeB permanent magnets when they move in a track.
