The cylinder 35 is fixed to the frame 1, and the cover plate 302 is fixedly connected to the output end of the cylinder 35.

With the above arrangement, when adjusting the angle of the magnet 100, the base 301 needs to rotate, and the cover plate 302 remains stationary during the rotation of the base 301, but since three sides of the magnet 100 are limited by the storage groove 311 and the bottom of the magnet 100 is supported by the stopper 312, during the rotation of the base 301, the cover plate 302 does not substantially act, and the cover plate 302 mainly prevents the magnet 100 from coming out of the storage groove 311 in the Y direction.

It should be noted that the magnet assembling apparatus may be used for assembling the magnet 100 of other products, and is not limited to VCM, and may be used whenever the magnet 100 needs to be turned at a certain angle in the assembling process. In addition, regarding the structure of the magnet 100, in the present embodiment, the magnet 100 has a columnar structure, and the cross-sectional shape of the magnet 100 may have a regular shape such as a rectangle, a square, a triangle, a trapezoid, or a circle. In other embodiments, the magnet 100 is a columnar structure, and the cross-sectional shape of the magnet 100 may be an irregular shape. To accommodate the various shapes of the magnet 100, in this embodiment, a surface of the cover 302 facing the base 301 has a planar structure.

It is to be understood that the above examples of the present invention are provided for clarity of illustration only and are not limiting of the embodiments of the present invention. Other variations or modifications of the above teachings will be apparent to those of ordinary skill in the art. It is not necessary here nor is it exhaustive of all embodiments. Any modification, equivalent replacement, improvement, etc. which come within the spirit and principles of the invention are desired to be protected by the following claims.
