Description

Technical Field

[0001] The present invention belongs to the technical field of automatic magnet loading, and particularly relates to a device for automatically loading magnetic steels into a circular fixture. Background Art

[0002] Neodymium-iron-boron permanent magnet materials have rapidly entered the industrial society with excellent magnetic properties, cost performance, and rich resource reserves. Before use, they need to undergo surface treatment operations, which are generally mainly completed through the production line on the surface treatment equipment. However, before entering the production line, the workpieces to be processed need to be loaded one by one and transferred into the processing equipment on the production line. Due to the special nature of neodymium-iron-boron permanent magnet materials, they need to rotate continuously in the tank of the processing equipment during surface treatment. Therefore, the magnet workpieces are all circular structures to ensure that the magnetic workpieces are thoroughly cleaned.

[0003] Currently, the loading process of workpieces to be processed mainly adopts manual loading. However, the manual loading method not only requires employees to have proficient and accurate operation skills, but also has problems such as low production efficiency and high labor intensity. In addition, due to the brittle characteristics of neodymium-iron-boron permanent magnet material workpieces, the products are extremely prone to chipping and breaking during processing or operation, resulting in increased production costs.

[0050] The blanking collection area 330 includes a circular fixture 320 and a fixture conveyor 12; after the circular fixture 320 is filled with magnets, the circular fixture 320 filled with magnets is automatically conveyed along the fixture conveyor 12 to the blanking storage area 3 and waits for manual transfer.
