After the assembly of this type of diaphragm-shaped composite magnet similar to the above-mentioned diaphragm-shaped composite magnet 200 is completed, the diaphragm-shaped composite magnet needs to be magnetized. In the existing magnetization equipment, the diaphragm-shaped magnet is not accurately positioned during the magnetization process, and the magnetization efficiency is low, which needs to be improved urgently.

A magnetizing plate 12 reciprocates between the magnetizing head 40 and the upper magnetizing head 30, and a groove 13 adapted to the shape of the diaphragm-like magnet is provided on the upper side of the magnetizing plate 12, and a positioning cone 131 corresponding to the through hole on the diaphragm-like magnet 200 is provided in the groove 13, and a through hole 132 corresponding to the magnetic block in the diaphragm-like magnet 200 is also provided at the bottom of the groove 13; the magnetizing push cylinder 11 can drive the magnetizing plate 12 to move so that the magnetic block in the diaphragm-like magnet 200 is aligned with the magnetizing coils in the upper magnetizing head 30 and the lower magnetizing head 40.

[0022] The present application can move the magnetizing plate back and forth between the magnet picking and placing station and the magnet magnetizing station through the magnetizing pushing cylinder. The edge of the groove on the magnetizing plate cooperates with the edge of the diaphragm-like magnet to position the diaphragm-like magnet.
