Description

Technical Field

[0001] The invention relates to magnet assembly technology, in particular to a magnet block rotating device for magnet block assembly. Background Art

[0002] With the advancement of technology, magnetic materials have been widely used in industries related to motors, electroacoustics, automobiles, and electronics. In the production and processing of electronic products, diaphragms (such as those for microphones, headphones, and speakers), and electroacoustic equipment, some devices require magnets that are not conventionally rectangular or circular. Magnets must be assembled into a designed shape and size based on product design requirements. For example, Chinese patent document CN111365337A discloses a "pressing fixture for special-shaped combined magnets," which includes two positioning plates mounted on a base plate and positioned between two sliders. The positioning plates are provided with multiple magnet assembly slots, each opening toward the sliders. The sliders are equipped with multiple push rods corresponding to the magnet assembly slots. When the sliders slide toward the middle of the positioning plates, the push rods press the multiple special-shaped magnet blocks within the magnet assembly slots into the slots to form a first special-shaped combined magnet. This helps workers quickly complete the press-fit assembly of special-shaped combined magnets.

[0003] During the processing of combined magnets, each magnetic block needs to be placed into the assembly jig as required. When the orientation of the magnetic block does not meet the requirements, the magnetic block needs to be flipped to adjust its orientation. Existing magnet assembly equipment lacks dedicated equipment for rotating magnetic blocks, and manual flipping is inefficient. Summary of the Invention

When the push rod 13 is extended upward, it can drive the rotating base 20 to rotate 90° around the horizontal rotating shaft 201, thereby causing the magnetic block in the open magnetic attraction groove to flip upward 90° with the rotating base 10.

[0021] The present application sets a hinge hole at a corner of the rotating seat, and installs the rotating seat on the upper side of the workbench through a horizontal rotating shaft. Push rods are respectively set in the guide vertical holes on both sides of the horizontal rotating shaft on the workbench. When one push rod is extended upward, it can drive the rotating seat to flip upward 90°, thereby realizing automatic rotation of the magnetic block. The structure is simple and reliable, and the magnetic block flipping operation is highly efficient.

[0022] In one embodiment of the present application, preferably, the open magnetic attraction groove on the rotating seat 20 is provided with an opening facing upward and an opening facing the side, so that after the rotating seat rotates 90° around the horizontal rotation axis 201, the open magnetic attraction groove still has one side opening facing upward.
