Background
Neodymium-iron-boron magnets are known as third generation rare earth permanent magnets. Since the advent of neodymium iron boron, neodymium iron boron has rapidly entered into industrialized society with excellent performance, price ratio and abundant resource reserves, and is widely used in high-tech fields such as electronics, communication, medical treatment, aviation, environmental protection and the like. The total value of the NdFeB permanent magnetic material in the 21 st century will account for 40% of the total value of the whole permanent magnetic material, and the pattern of the whole ten permanent magnetic materials will be changed.
The neodymium iron boron magnet is easy to oxidize in the air and is easy to corrode in many environments, so that the magnetic property is reduced, and the service life is shortened. At present, the main method for protecting the neodymium iron boron magnet is to perform surface treatment such as electroplating or coating treatment on the surface of the neodymium iron boron magnet. In the prior art, Chinese patent with publication number CN106435678B discloses an electroplating pretreatment method and equipment for a neodymium iron boron magnet, wherein a sintered neodymium iron boron magnet and a proper amount of steel balls are uniformly mixed and then are placed in a specific roller, and the surface of the sintered neodymium iron boron magnet is sequentially subjected to pretreatment procedures of ultrasonic chemical oil removal, hot water washing, nitric acid pickling, primary water washing, chemical ash removal, ultrasonic water washing, secondary water washing and the like by utilizing the rolling of the roller, and then surface nickel plating layer electroplating is carried out. In the actual production process, the steel balls are called plating accompanying steel balls which are recycled, the neodymium iron boron magnet and the plating accompanying steel balls are required to be separated after the working procedures are completed, the neodymium iron boron magnet is generally flaky, the plating accompanying steel balls are spherical, the sieve (shown in figure 7) with rectangular strip-shaped through holes on the bottom plate is manually screened and separated in the prior art, and the flaky neodymium iron boron magnet penetrates through the rectangular strip-shaped through holes to be leaked out and is cut and left in the sieve in the screening process. Manually shaking the screen is time consuming and labor intensive and, therefore, further improvements are needed.
