DETAILED DESCRIPTION

[0026] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments.

[0027] In one embodiment, Figure 1-Figure 6 As shown, a magnetizing tool for producing NdFeB magnets includes a magnetizing cover 405 and a sliding seat 300 for loading a jig carrying a magnet body 307, and also includes a dust removal mechanism, wherein the dust removal mechanism has a dust hood 500 capable of covering the jig loaded with the magnet body 307, a dust collection station is provided on the movement trajectory of the sliding seat 300, when the sliding seat 300 is in the dust collection station, the dust collection hood 500 is located directly above the sliding seat 300, the dust removal mechanism is provided with a pressing mechanism for driving the dust collection hood 500 to move downward and press the sliding seat 300, the sliding seat 300 is provided with an exhaust hole 301 running through from top to bottom, and a filter assembly covering all the exhaust holes 301 is provided at the bottom of the sliding seat 300.

[0028] The sliding seat 300 is slidably arranged on the base 100, and a sliding rail 200 is arranged on the upper surface of the base 100. A driving motor 201 is arranged on the surface of the base 100. The output end of the driving motor 201 passes through the base 100 and is fixedly connected to the threaded rod 202. A turntable 203 is arranged on the inner wall of the sliding rail 200. The end of the threaded rod 202 is rotatably connected to the surface of the turntable 203. A sliding block 204 is arranged on the middle thread of the threaded rod 202. Slide grooves 205 are arranged on both sides of the sliding rail 200. A slider 206 is slidably arranged inside the slide groove 205. The sliding block 204 is connected to the upper end of the slider 206 through the sliding seat 300. When in use, the driving motor 201 is started to rotate the threaded rod 202, so that the sliding block 204 drives the sliding seat 300 to move within the range of the sliding rail 200.

[0029] The sliding seat 300 is provided with a control mechanism on both side walls, the control mechanism includes a sensor 600 arranged on the two side walls of the sliding seat 300, a receiver 601 matched with the sensor 600 is provided on the base 100, a driving box 400 is provided at the upper end of the base 100, a motor 401 is provided at the bottom of the driving box 400, a screw rod 402 is provided at the output end of the motor 401, a bearing 403 is provided at the top end of the driving box 400, the surface of the bearing 403 is rotatably connected to the end of the screw rod 402, a screw rod sleeve 404 is provided in the middle thread of the screw rod 402, and the screw rods on both sides are provided. The rod sleeve 404 is connected to the magnetizing cover 405 and the dust collecting cover 500 respectively. When the sliding seat 300 moves within the range of the sliding rail 200, if the receiver 601 receives a signal from the sensor 600, the receiver 601 will control the driving motor 201 to stop and stop the sliding seat 300 at a specified position. At this time, the motor 401 can be started to rotate the screw rod 402, and the magnetizing cover 405 and the dust collecting cover 500 are driven by the screw rod sleeve 404 to cover the fixture loaded with the magnet body 307, and perform magnetization and dust collecting operations.

[0030] The pressing mechanism includes a support rod 505 installed inside the dust cover 500, and a pressure net 506 is provided at the end of the support rod 505. When the dust collection operation is performed, the pressure net 506 will press the limiting plate 306 on the placement box 303, so that the limiting plate 306 can be always placed on the placement box 303, which can prevent the magnet body 307 placed inside the placement box 303 from being sucked out of the placement box 303 due to excessive suction during the dust collection operation.

[0031] The dust removal mechanism includes a dust hood 500, a dust suction pipe 501, an air pump 503 and a dust collecting box 502. The dust hood 500 is provided with a dust suction pipe 501. The end of the dust suction pipe 501 is connected to the output end of the air suction pump 503. The output end of the air suction pump 503 is connected to the dust collecting box 502. When performing a dust removal operation, it is necessary to start the air suction pump 503, and place the hood in the dust hood 500 through the dust suction pipe 501, and the dust on the surface of the magnet body 307 on the placement box 303 is sucked into the dust collecting box 502.

[0032] A dust box 504 for collecting dust is slidably provided inside the dust box 502. The dust sucked into the dust box 502 through the dust suction pipe 501 will enter the dust box 504 and be collected. When cleaning is required, the staff can pull out the dust box 504 to clean the dust inside it.

[0033] The filter assembly includes a filter 302, which is installed at the bottom of the sliding seat 300. The filter 302 cooperates with the exhaust hole 301. When the dust collection operation is performed, the outside air will be sucked into the placement box 303 through the exhaust hole 301 at the bottom of the sliding seat 300. In this process, the outside air will sweep the surface of the magnet body 307, and blow away the dust on the surface of the magnet body 307, and suck it into the dust collection box 502 through the dust cover 500. In this process, the filter 302 installed at the position of the exhaust hole 301 prevents dust in the outside air from entering the placement box 303 and causing double pollution to the magnet body 307.

[0034] The fixture includes a placement box 303, and a plurality of placement grooves 304 are evenly distributed on the surface of the placement box 303. A magnet body 307 is placed inside each placement groove 304. A limiting plate 306 for limiting the magnet body 307 from escaping from the placement groove 304 is provided on the surface of the placement box 303. When in use, the magnet body 307 is first placed inside the placement groove 304, and then the limiting plate 306 is covered on the placement box 303 to limit the positioning of the magnet body 307 inside it.

[0035] The placement box 303 is provided with a through hole 305 which runs through from top to bottom. When performing a vacuuming operation, outside air is introduced into the placement box 303 through the through hole 305 to clean the dust on the surface of the magnet body 307, thereby facilitating the vacuuming operation.

[0036] When in use, the staff first places the magnet body 307 to be magnetized inside the placement box 303, covers the limiting plate 306, and then places the placement box 303 above the sliding seat 300. At this time, the driving motor 201 is started to rotate the threaded rod 202, so that the sliding block 204 drives the sliding seat 300 to move within the range of the slide rail 200. When the sliding seat 300 moves within the range of the slide rail 200, if the receiver 601 receives a signal from the sensor 600, the receiver 601 will control the driving motor 201 to stop and stop the sliding seat 300 at the specified position. At this time, the motor 401 can be started to rotate the screw rod 402, and the dust cover 500 is driven by the screw rod sleeve 404 to cover the fixture loaded with the magnet body 307. When the dust cover 500 covers the placement box 303, the pressure net 506 arranged inside it will press the limiting plate 306 on the placement box 303 to prevent suction During the dust collection operation, the suction force is too strong to suck the magnet body 307 placed inside the placement box 303 out of the placement box 303, and then the air pump 503 is started to draw the outside air into the placement box 303 through the suction hole 301 and the through hole 305, and the dust on the surface of the magnet body 307 is sucked into the dust box 502, wherein the dust sucked into the dust box 502 will enter the dust box 504 for collection, which is convenient for the staff to clean the dust. When the dust collection operation is completed, the motor 401 is started to make the dust collection hood 500 rise, and then the driving motor 201 is started to make the sliding seat 300 drive the placement box 303 carrying the magnet body 307 to move to the bottom of the magnetizing hood 405, and then the motor 401 is started to make the magnetizing hood 405 descend to cover the placement box 303. At this time, the magnetizing hood 405 can be started so that the magnetizing hood 405 performs a magnetizing operation on the magnet body 307 inside the placement box 303.

[0037] The above embodiments only express one or several implementation methods of the present invention, and the description is relatively specific and detailed, but it cannot be understood as limiting the scope of the present invention. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the present invention, which all belong to the protection scope of the present invention. Therefore, the protection scope of the present invention shall be based on the attached claims.
