[0002] An electromagnetic chuck uses the electromagnetic principle to generate magnetic force by energizing the internal coil, and then tightly sucks the workpiece in contact with the surface of the panel through the magnetic conductive panel. The annular electromagnetic chuck is an annular magnetic conductor.

[0003] The patent specification with announcement number CN217947326U discloses a ring-shaped multi-module electromagnetic suction cup. In this application, it is composed of a lifting plate body and 8 cylindrical electromagnetic suction cups with large suction force. A single suction cup can absorb 200kg of metal. If there is a gap between the suction cup and the metal, the suction force is slightly reduced, and a variety of suction cups can be replaced according to the weight of the product. At the same time, this tooling can adjust the position of the electromagnetic suction cup according to the size of the product to complete the handling. The eight evenly distributed suction cups can effectively absorb the product and ensure that the internal structure of the product does not change. The number of suction cups is set to eight. If some individual electromagnetic suction cups are damaged, the weight of the remaining magnets is sufficient to meet the conditions for transporting the product. At the same time, each can be equipped with an uninterruptible power supply through an external power supply to ensure the power supply of the electromagnet, thereby improving the stability and firmness of the electromagnetic suction cup during use.
