Description

Technical Field

[0001] The present invention relates to the technical field of magnetic core preparation, and specifically to a preparation process for an asymmetric segmented high-frequency low-loss magnetic core. Background Art

[0002] Magnetic core preparation equipment is a special device used to manufacture the core of magnetic components, mainly serving the fields of electronics and power. Its core functions include material forming, precision machining, and performance testing. By optimizing the material formula and process parameters, the equipment can produce magnetic cores with high-frequency low loss and high stability, which are widely used in transformers, inductors, wireless charging modules, etc.

[0003] In the existing magnetic core production equipment, when cutting the magnetic core, a laser cutter is used to cut the magnetic core. After the cutting is completed, the waste cut from the magnetic core falls onto the platform supporting the magnetic core. Since the waste generated by laser cutting has a high temperature when cut off, the waste will stick to the platform, which is not convenient for the staff to clean the platform.

[0004] Therefore, in view of the above problems, a preparation process for an asymmetric segmented high-frequency low-loss magnetic core is proposed. Summary of the Invention

[0005] In order to make up for the deficiencies of the existing technology and solve the problem of inconvenient cleaning of the cutting waste on the platform supporting the magnetic core, the present invention proposes a preparation process for an asymmetric segmented high-frequency low-loss magnetic core.

[0006] A preparation process for an asymmetric segmented high-frequency low-loss magnetic core is characterized in that the process includes the following steps: S1: Place the magnetic core in the magnetic core preparation equipment and fix the magnetic core through this preparation equipment; S2: Then cut the magnetic core through a cutting mechanism; S3: After the cutting is completed, clean the surface of the suction cup through a cleaning unit; Wherein the main body of the magnetic core preparation equipment includes: A support plate; A top plate and a ceramic table fixedly connected to the support plate; A sealing plate slidably mounted on the outer surface of the top plate; A laser cutter movably mounted at the bottom of the top plate; A cleaning unit is provided on the top of the support plate. The cleaning unit is used to clean the cutting waste on the top of the ceramic table. The cleaning unit includes two limit plates. A scraper is slidably connected to the inner surfaces of the two limit plates. One side of the scraper is threadedly connected to a threaded rod. One end of the threaded rod is fixedly connected to a third motor. The third motor is fixedly installed on one side of the ceramic table. The top of the support plate is provided with a second groove and a first groove. A third groove is provided on the inner surface of the second groove. A receiving box is slidably installed on the inner surface of the third groove. Two limit blocks are fixedly installed on the inner surface of the second groove. A magnetic core body is movably installed on the top of the ceramic table.

[0007] Preferably, the cross-section of the magnetic core body is a trapezoid with a top width of 30 mm, a bottom width of 50 mm, and a height of 20 mm.

[0008] Preferably, four support legs are fixedly installed at the bottom of the support plate. A control board is fixedly installed on one side of the support plate. Four support columns are fixedly installed on the top of the support plate. The top plate is fixedly installed on the tops of the four support columns. Two third electric telescopic rods are fixedly installed on the top of the support plate, and the output ends of the third electric telescopic rods are slidably connected to the top plate. The output ends of the third electric telescopic rods are fixedly installed on the top of the sealing plate. A sealing gasket is fixedly installed at the bottom of the sealing plate.

[0009] Preferably, a fourth groove is provided on one side of the sealing plate. A mounting frame is fixedly installed on the inner surface of the fourth groove. One side of the mounting frame is fixedly installed with a telescopic rod. A spring is wound around the outer surface of the telescopic rod. A sliding plate is slidably installed on the inner surface of the fourth groove. The sliding plate is fixedly connected to the telescopic rod.

[0010] Preferably, a second motor is fixedly installed on the top of the top plate. The output shaft of the second motor penetrates the top plate and is fixedly connected to a first electric telescopic rod. The output end of the first electric telescopic rod is fixedly connected to a second electric telescopic rod. The output end of the second electric telescopic rod is fixedly connected to a connecting block. The laser cutter is rotatably installed on the inner surface of the connecting block. A first motor is fixedly installed on one side of the connecting block. The output shaft of the first motor is fixedly connected to the outer surface of the laser cutter.

[0011] Preferably, four fifth grooves are provided on the top of the ceramic table. A filter screen is fixedly installed on the inner surface of the fifth grooves. The four fifth grooves are commonly connected through a suction pipe. One end of the suction pipe is fixedly connected to a vacuum pump. The vacuum pump is fixedly installed at the bottom of the support plate.

[0012] Preferably, a cooling groove is provided in the inner cavity of the ceramic table. Water pipes are fixedly installed on both sides of the ceramic table, and both water pipes are communicated with the cooling groove. The two water pipes are respectively connected to a water tank and a water pump through a through connection. The water pump and the water tank are mutually communicated.

[0013] Preferably, an argon gas tank is fixedly installed on the top of the top plate. One end of the argon gas tank is fixedly connected to a gas delivery pipe. A valve is fixedly installed on the outer surface of the gas delivery pipe. One end of the gas delivery pipe penetrates through the top plate.

[0014] The beneficial effects of the present invention are as follows: 1. By means of a vacuum pump, the inner cavity of the fifth groove is in a negative pressure state, which can stably adsorb the magnetic core body on the top of the ceramic table. Then, the height of the laser cutter is adjusted by the second electric telescopic rod, the distance between the laser cutter and the magnetic core body is adjusted by the first electric telescopic rod. The laser cutter can perform a 360° rotary cutting on the magnetic core body through the second motor. The laser cutter can adjust the cutting angle of the magnetic core body by the rotation of the output shaft of the first motor. During the cutting process, the cooling water in the cooling tank circulates through the cooperation of the water pump and the water tank to cool the ceramic table.

[0015] 2. The output end of the third electric telescopic rod moves the sealing plate downward. At this time, the support plate, the top plate and the sealing plate jointly form a sealed space. Then, the argon gas tank is controlled by a valve to deliver argon gas into the sealed space through the gas delivery pipe. The argon gas can squeeze out the air in the sealed space, and the air squeezes the sliding plate out of the inner cavity of the fourth groove. The spring and the telescopic rod are stretched. When the sealed space is filled with argon gas, the output of argon gas stops. At this time, the sliding plate returns to the inner cavity of the fourth groove again. Annealing in argon gas can ensure that the performance of the magnetic core body will not be affected by cutting.

[0016] 3. The output shaft of the third motor drives the threaded rod to rotate. The threaded rod drives the scraper to slide along the limiting plate. At this time, the scraper can push the waste on the top of the ceramic table into the receiving box. At the same time, the filter screen can prevent the waste from falling into the fifth groove.

Detailed implementation manners

[0020] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0021] Please refer to Figures 1 to 9 As shown, a preparation process for an asymmetric segmented high-frequency low-loss magnetic core is characterized in that the process includes the following steps: S1: Place the magnetic core in the magnetic core preparation equipment and fix the magnetic core through this preparation equipment; S2: Then cut the magnetic core through the cutting mechanism; S3: After cutting, clean the surface of the suction cup through the cleaning unit; Among them, the main body of the magnetic core preparation equipment includes: A support plate 1; A top plate 21 and a ceramic table 3 fixedly connected to the support plate 1; A sealing plate 23 slidably mounted on the outer surface of the top plate 21; A laser cutter 215 movably mounted at the bottom of the top plate 21; A cleaning unit provided on the top of the support plate 1, and the cleaning unit is used to clean the cutting waste on the top of the ceramic table 3; the cleaning unit includes two limit plates 301, and a scraper 302 is slidably connected to the inner surfaces of the two limit plates 301. One side of the scraper 302 is threadedly connected to a threaded rod 303. One end of the threaded rod 303 is fixedly connected to a third motor 304. The third motor 304 is fixedly installed on one side of the ceramic table 3. A second groove 13 and a first groove 12 are formed on the top of the support plate 1. A third groove 131 is formed on the inner surface of the second groove 13. A receiving box 132 is slidably mounted on the inner surface of the third groove 131. Two limit blocks 133 are fixedly installed on the inner surface of the second groove 13. A magnetic core body 10 is movably mounted on the top of the ceramic table 3; The cross-section of the magnetic core body 10 is a trapezoid with a top width of 30 mm, a bottom width of 50 mm, and a height of 20 mm.

[0022] After the cutting of 10 is completed, it is necessary to collect and process the waste generated by the cutting.

[0023] When the present invention is in use, first, the magnetic core body 10 is fixed on the top of the ceramic table 3, and then the magnetic core body 10 is cut by the laser cutter 215 into a trapezoid with a top width of 30 mm, a bottom width of 50 mm, and a height of 20 mm. Then, the cut magnetic core body 10 is removed from the ceramic table 3. The waste generated when cutting the magnetic core body 10 will remain on the top of the ceramic table 3. At this time, the output shaft of the third motor 304 drives the threaded rod 303 to rotate, and the threaded rod 303 drives the scraper 302 to slide along the inner surface of the limit plate 301. This can make the scraper 302 completely slide across the top of the ceramic table 3 and scrape the waste remaining on the top of the ceramic table 3 into the receiving box 132. Finally, the staff can take out the receiving box 132 from the inner surface of the third groove 131 to process the waste in the inner cavity of the receiving box 132.

[0024] Furthermore, as Figure 2As shown in the figure, four support legs 11 are fixedly installed at the bottom of the support plate 1, a control board 14 is fixedly installed on one side of the support plate 1, four support columns 2 are fixedly installed on the top of the support plate 1, a top plate 21 is fixedly installed on the tops of the four support columns 2, two third electric telescopic rods 22 are fixedly installed on the top of the support plate 1, and the output end of the third electric telescopic rod 22 is slidably connected to the top plate 21. The output end of the third electric telescopic rod 22 is fixedly installed on the top of the sealing plate 23, and a sealing gasket 211 is fixedly installed at the bottom of the sealing plate 23.

[0025] When the present invention is in use, the electronic components on the entire magnetic core preparation device can be controlled through the control board 14. During cutting, by contracting the two third electric telescopic rods 22, the sealing plate 23 can slide on the outer surface of the top plate 21. Finally, the sealing gasket 211 contacts the top of the support plate 1. By covering with the sealing plate 23, the influence on the outside during magnetic core cutting can be reduced.

[0026] Further, as Figure 4 shown, a fourth groove 231 is formed on one side of the sealing plate 23. An installation frame 232 is fixedly installed on the inner surface of the fourth groove 231. One side of the installation frame 232 is fixedly installed with a telescopic rod 234. A spring 235 is wound around the outer surface of the telescopic rod 234. A sliding plate 236 is slidably installed on the inner surface of the fourth groove 231, and the sliding plate 236 is fixedly connected to the telescopic rod 234.

[0027] When the present invention is in use, the air enclosed in the inner cavity of the sealing plate 23 can be discharged through the fourth groove 231. When discharging, the air pressure in the inner cavity of the fourth groove 231 is greater than the air pressure outside the fourth groove 231. At this time, the air inside the fourth groove 231 pushes out the sliding plate 236, and the telescopic rod 234 and the spring 235 are stretched. When the air pressure in the inner cavity of the fourth groove 231 is less than or equal to the external pressure, the sliding plate 236 returns to the inner cavity of the fourth groove 231 again to seal the inner cavity of the sealing plate 23.

[0028] Further, as shown in Figure 5, a second motor 217 is fixedly installed on the top of the top plate 21. The output shaft of the second motor 217 penetrates the top plate 21 and is fixedly connected to a first electric telescopic rod 212. The output end of the first electric telescopic rod 212 is fixedly connected to a second electric telescopic rod 213. The output end of the second electric telescopic rod 213 is fixedly connected to a connecting block 214. A laser cutter 215 is rotatably installed on the inner surface of the connecting block 214. A first motor 216 is fixedly installed on one side of the connecting block 214, and the output shaft of the first motor 216 is fixedly connected to the outer surface of the laser cutter 215.

[0029] When the present invention is in use, when it is necessary to adjust the cutting angle of the laser cutter 215, the output shaft of the second motor 217 drives the first electric telescopic rod 212 to rotate, and the first electric telescopic rod 212 further drives the second electric telescopic rod 213 to move. Through the cooperation of the second motor 217, the first electric telescopic rod 212 and the second electric telescopic rod 213, the laser cutter 215 can be moved in multiple directions, thereby realizing the cutting of the magnetic core body 10.

[0030] Furthermore, as Figure 6 shown, four fifth grooves 31 are opened at the top of the ceramic table 3. A filter screen 32 is fixedly installed on the inner surface of the fifth groove 31. The four fifth grooves 31 are jointly and communicatively connected with a suction pipe 33. One end of the suction pipe 33 is fixedly connected with a vacuum pump 34, and the vacuum pump 34 is fixedly installed at the bottom of the support plate 1.

[0031] When the present invention is in use, before cutting the magnetic core body 10, the magnetic core body 10 is first placed on the tops of the three fifth grooves 31. The inner cavity of the fifth groove 31 is in a negative pressure state through the vacuum pump 34. At this time, under the action of the atmospheric pressure, the magnetic core body 10 will be tightly adsorbed on the top of the ceramic table 3. When cleaning the waste on the top of the ceramic table 3 through the scraper 302 after cutting, the filter screen 32 can prevent the waste from falling into the inner cavity of the fifth groove 31.

[0032] Furthermore, as Figure 8 shown, a cooling groove 35 is opened in the inner cavity of the ceramic table 3. Water pipes 351 are fixedly installed on both sides of the ceramic table 3, and both water pipes 351 are communicated with the cooling groove 35. The two water pipes 351 are respectively communicatively connected with a water tank 352 and a water pump 353, and the water pump 353 and the water tank 352 are mutually communicated.

[0033] When the present invention is in use, in order to prevent the temperature of the ceramic table 3 from being too high when cutting the magnetic core body 10, it is necessary to cool the ceramic table 3. The cooling water in the inner cavity of the water tank 352 is pumped out through the water pump 353, and the cooling water is circulated in the inner cavity of the cooling groove 35 through the cooperation of the two water pipes 351, so as to achieve the purpose of cooling the ceramic table 3.

[0034] Furthermore, as Figure 9 shown, an argon gas tank 42 is fixedly installed on the top of the top plate 21. One end of the argon gas tank 42 is fixedly connected with a gas transmission pipe 4. A valve 41 is fixedly installed on the outer surface of the gas transmission pipe 4. One end of the gas transmission pipe 4 penetrates through the top plate 21.

[0035] When the present invention is in use, after the magnetic core body 10 is cut, annealing work needs to be carried out on the magnetic core body 10. The valve 41 can control the delivery and closing of argon in the argon gas cylinder 42. The argon in the inner cavity of the argon gas cylinder 42 enters the enclosed space jointly formed by the support plate 1, the top plate 21 and the sealing plate 23 through the gas delivery pipe 4. During the process of delivering argon, the air in the enclosed space will be gradually extruded by the argon through the fourth groove 231. When the enclosed space is filled with argon, the magnetic core body 10 can be stably annealed.

[0036] Working principle: First, place the magnetic core body 10 on the top of the ceramic table 3. The vacuum pump 34 makes the inner cavity of the fifth groove 31 in a negative pressure state, which can stably adsorb the magnetic core body 10 on the top of the ceramic table 3. Then, adjust the height of the laser cutter 215 through the second electric telescopic rod 213, adjust the distance between the laser cutter 215 and the magnetic core body 10 through the first electric telescopic rod 212. The second motor 217 can make the laser cutter 215 perform 360° rotary cutting on the magnetic core body 10. The output shaft of the first motor 216 drives the laser cutter 215 to rotate, which can adjust the cutting angle of the laser cutter 215 on the magnetic core body 10. During the cutting process, the water pump 353 cooperates with the water tank 352 to make the cooling water in the cooling cavity 35 circulate to cool the ceramic table 3.

[0037] After cutting, the sealing plate 23 is lowered by the output end of the third electric telescopic rod 22. At this time, the support plate 1, the top plate 21 and the sealing plate 23 jointly form an enclosed space. Then, the valve 41 controls the argon gas cylinder 42 to deliver argon into the enclosed space through the gas delivery pipe 4. The argon can extrude the air in the enclosed space, and the air extrudes the sliding plate 236 out of the inner cavity of the fourth groove 231, and the spring 235 and the telescopic rod 234 are stretched. When the enclosed space is filled with argon, the output of argon stops. At this time, the sliding plate 236 returns to the inner cavity of the fourth groove 231 again. Annealing in argon can ensure that the performance of the magnetic core body 10 will not be affected by cutting. After annealing, the output shaft of the third motor 304 drives the threaded rod 303 to rotate, and the threaded rod 303 drives the scraper 302 to slide along the limiting plate 301. At this time, the scraper 302 can push the waste on the top of the ceramic table 3 into the receiving box 132. At the same time, the filter screen 32 can prevent the waste from falling into the fifth groove 31.
