Finally, the product transmission line 1 transmits the pallet to the next process. In this embodiment, the demagnetizer can realize a series of processes such as automatic loading, demagnetization, magnetic flux detection and unloading of the product, with a high degree of automation, which reduces the time and labor intensity of manual operation, thereby improving the efficiency of the demagnetization process.
