[0001] This utility model relates to magnet manufacturing technology, and in particular to a rotary worktable for spraying annular magnets. Background Technology

[0002] Magnets are widely used basic electronic and electrical components, primarily found in computers, mobile phones, televisions, communications, toys, audio equipment, automation equipment, and MRI. Currently, neodymium iron boron magnets are widely used as high-performance permanent magnets. In the production and processing of electronic products, diaphragms (microphone, headphone, speaker, etc.), and electroacoustic equipment, some equipment requires magnets that are not conventionally rectangular or circular shapes. Depending on the product processing requirements, magnets need to be assembled into a shape and size suitable for the specific equipment.

[0003] For example, the magnetic ring assembly disclosed in the Chinese utility model patent document "CN202222384665.X A magnetic component and a magnetic ring assembly having the magnetic component" has multiple magnetic components arranged in a ring structure. Some of these ring-shaped combined magnets also require a protective coating to be sprayed on the surface of the magnet. Currently, there is a lack of worktables for spraying the surface of such ring magnets, resulting in non-standard spraying operations, poor coating thickness consistency, and low spraying efficiency. Utility Model Content

[0004] The purpose of this invention is to provide a rotary worktable to solve the problem of low efficiency in the existing ring magnet spraying process.

[0005] To address the aforementioned problems, this utility model provides a rotary worktable with a rotating frame mounted on a base plate. The rotating frame carries a spray coating material plate. The rotating frame includes a rotating base and two T-shaped support frames.

Specifically, one end of the main beam of the T-shaped support frame 12 is fixedly connected to the rotating seat 11, and the other end of the main beam of the T-shaped support frame 12 is fixedly connected to the center of the crossbeam. Spraying material carrier plates 101 are respectively installed at both ends of the crossbeam.

In the aforementioned rotary worktable of this application, two T-shaped support frames can rotate relative to the base plate with the rotating seat. After the magnet to be sprayed on the spraying carrier plate on one T-shaped support frame has completed the spraying operation, the rotating seat can rotate 180° to spray the magnet to be sprayed on the spraying carrier plate on the other T-shaped support frame, thereby improving the spraying efficiency. During the spraying operation, the first motor can drive the spraying carrier plate on the support frame to rotate, thereby allowing the magnet to be sprayed from all directions, resulting in a uniform coating.

[0028] In one embodiment of this application, preferably, the spraying carrier plate 101 is provided with a grid support, and the upper side of the grid support is evenly distributed with annular carrier rings 102.

[0033] In one embodiment of this application, preferably, a second motor 26 is also installed on the lower side of the base plate 100 to drive the central rotating shaft 114 to rotate. The second motor 26 drives the central rotating shaft 114 and the rotating seat 11 to rotate, thereby driving the rotating frame 10 to rotate to change the position of the spraying carrier plate 101.
