Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of magnetic core processing, in particular to a magnetic core stamping forming auxiliary equipment. BACKGROUND

[0002] With the development of electronic information technology, the requirements of high frequency, miniaturization and intelligence are put forward for components and devices made of magnetic materials. As key components of circuits, there is a strong demand for increasing the use frequency of components and devices made of magnetic materials, which are widely used in computers, mobile phones, automation equipment and electronic transformers.

[0003] In the process of making ferrite magnetic cores, processes such as powder making, pressing and sintering are required. In the traditional pressing process, gaps will be generated in the mold after a period of use, and the magnetic cores pressed out will have burrs, affecting the appearance, and in severe cases, the enameled copper wire will be scratched, resulting in poor voltage resistance and other adverse phenomena.

[0004] In the prior art, the surface burrs of the pressed magnetic cores are usually wiped by manual use of a brush. However, this method requires a large amount of manpower and has low wiping efficiency, and the wiped magnetic cores need to be further transported to other process positions for secondary transportation. Although there is a design of suspending a brush roller on the magnetic core transmission line to remove the burrs of the magnetic cores, avoiding manual wiping and secondary transportation, this device can only remove the burrs on the top or side of the magnetic core, and cannot remove the burrs on the inner hole and bottom of the magnetic core. SUMMARY

[0005] Therefore, the purpose of the present application is to provide a magnetic core stamping forming auxiliary equipment that can comprehensively remove the burrs of the magnetic core during transportation, to solve the problem that there is no such equipment in the prior art.

[0006] The magnetic core stamping forming auxiliary equipment provided by the present application comprises a first sliding rail connected to a stamping equipment at one end, a second sliding rail arranged below the other end of the first sliding rail, and a turnover brush cleaning assembly arranged between the first sliding rail and the second sliding rail, and end face brush cleaning devices suspended above the sliding rails and side face brush cleaning devices arranged on both sides of the sliding rails are arranged above the first sliding rail and the second sliding rail;

[0007] The turnover brush cleaning assembly comprises a turnover block, a positioning sliding rail adapted to the first sliding rail arranged on the top of the turnover block, a brush roller arranged in the turnover block, an annular magnetic attraction device, and a driving component and a rotating shaft arranged on both sides of the turnover block, respectively.

[0008] The turnover block is provided with a circular groove for placing the annular magnetic attraction device, the bottom of the circular groove is provided with a mounting hole, the brush roller comprises a vertical rod and a brush arranged on one side of the vertical rod, the other end of the vertical rod is provided with a limiting ring matched with the mounting hole and placed in the mounting hole, so that the brush roller is fixed on the turnover block and rotates relative to the turnover block, one end of the vertical rod provided with the brush is placed in the circular groove, one side of the turnover block is provided with an avoiding groove, one end of the rotating shaft is used for connecting with a fixed object, the other end is provided with a first bevel gear and placed in the avoiding groove, the vertical rod is provided with a second bevel gear matched with the first bevel gear, and the rotating shaft of the driving component is fixedly connected with the turnover block;

[0009] When the circular ring-shaped magnetic core enters the circular groove through the first sliding rail and the positioning sliding rail, the magnetic core is adsorbed and fixed through the annular magnetic attraction device, and the driving component drives the turnover block to overturn, the brush roller rotates under the action of the bevel gear while the turnover block rotates relative to the rotating shaft, so as to clean and brush the inner hole of the magnetic core, and the magnetic core is overturned and enters the second sliding rail.

[0010] The above-mentioned magnetic core stamping forming auxiliary equipment is provided with end face cleaning and brushing devices and side face cleaning and brushing devices on the first sliding rail, so as to remove burrs on the top end face and side face of the circular ring-shaped magnetic core formed by the stamping equipment and entering the first sliding rail, and then the magnetic core is overturned by 180 degrees by the overturning and brushing assembly and enters the second sliding rail, so that the end face cleaning and brushing devices and the side face cleaning and brushing devices on the second sliding rail remove burrs on the bottom end face and side face of the magnetic core. In addition, the inner hole of the magnetic core is also removed of burrs when the overturning and brushing assembly overturns the magnetic core. Specifically, after the magnetic core enters the positioning sliding rail from the first sliding rail, the magnetic core is partially sunk into the circular groove under the action of the positioning sliding rail, the magnetic core is adsorbed by the annular magnetic attraction device, so that the magnetic core is completely sunk into the circular groove and sleeved outside the brush roller. At this time, the driving component drives the turnover block to rotate relative to the rotating shaft. Since the rotating shaft is provided with a first bevel gear, the brush roller is provided with a second bevel gear matched with the first bevel gear, and the brush roller is fixed on the turnover block and rotates relative to the turnover block by matching the limiting ring with the mounting hole. Therefore, the brush roller rotates relative to the turnover block due to the cooperation of the bevel gears while the turnover block rotates. The part of the brush roller provided with the brush is arranged in the circular groove, and the magnetic core is sleeved outside the brush roller at this time. Therefore, the brush roller will clean and brush the burrs of the inner hole of the magnetic core. After the overturning is completed, the annular magnetic attraction device is released from adsorption, so that the magnetic core falls into the second sliding rail from the circular groove. Therefore, the magnetic core stamping forming auxiliary equipment completes the overall burr cleaning process of the magnetic core in the process of transferring the magnetic core. Therefore, the present application solves the problem that there is no magnetic core stamping forming auxiliary equipment for removing burrs of the magnetic core in the process of transferring the magnetic core in the prior art.

The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0033] Referring to Figures 1 to 5 ​​​, as shown is magnetic core stamping forming auxiliary equipment in an embodiment of the present application, including a first slide rail 10 for connecting the stamping equipment at one end, the second slide rail 20 is arranged below the other end of the first slide rail 10, and the turnover brush assembly 30 is arranged between the first slide rail 10 and the second slide rail 20, the first slide rail 10 and the second slide rail 20 are both provided with end face brush device 40 suspended above the slide rail and side face brush device 50 arranged on both sides of the slide rail, wherein:

[0034] The turnover brush assembly 30 includes a turnover block 31, a positioning slide rail 32 arranged on the top of the turnover block 31 and adapted to the first slide rail 10, a brush roller 33 arranged in the turnover block 31, an annular magnetic attraction device 34, and a driving component 35 and a rotating shaft 36 arranged on both sides of the turnover block 31 respectively, the turnover block 31 is provided with a circular groove 311 for placing the annular magnetic attraction device 34, the bottom of the circular groove 311 is provided with a mounting hole 312, the brush roller 33 includes a vertical rod 331 and a brush 332 arranged on one side of the vertical rod 331, the other end of the vertical rod 331 is provided with a limiting ring 333 adapted to the mounting hole 312 and placed in the mounting hole 312, so that the brush roller 33 is fixed on the turnover block 31 and rotates relative to the turnover block 31, one end of the vertical rod 331 provided with the brush 332 is placed in the circular groove 311, one side of the turnover block 31 is provided with an avoiding groove 313, one end of the rotating shaft 36 is used for connecting with a fixed object, the other end is provided with a first bevel gear 361 and placed in the avoiding groove 313, the vertical rod 331 is provided with a second bevel gear 334 adapted to the first bevel gear 361, the rotating shaft of the driving component 35 is fixedly connected with the turnover block 31;

[0035] When the circular magnetic core passes through the first slide rail 10 and the positioning slide rail 32 into the circular groove 311, the magnetic core is attracted and fixed by the annular magnetic attraction device 34, and the driving component drives the turnover block 31 to turn over, the turnover block 31 rotates relative to the rotating shaft 36, and the brush roller 33 rotates under the action of the bevel gear, so as to clean and brush the inner hole of the magnetic core, and the magnetic core is turned over and enters the second slide rail 20.

[0036] It can be understood that in specific use, by setting the end face brush device 40 and the side face brush device 50 on the first slide rail 10, the burrs on the top end face and the side face of the ring-shaped magnetic core formed into the first slide rail 10 from the stamping equipment are removed, and then the magnetic core is turned by 180 degrees by the turnover brush assembly 30 into the second slide rail 20, so that the end face brush device 40 and the side face brush device 50 on the second slide rail 20 remove the burrs on the bottom end face and the side face of the magnetic core, and in addition, the inner hole of the magnetic core is removed by the turnover brush assembly 30 when the magnetic core is turned. Specifically, when the magnetic core enters the positioning slide rail 32 from the first slide rail 10, under the action of the positioning slide rail 32, the magnetic core partially falls into the circular groove 311, and the magnetic core is adsorbed by the annular magnetic attraction device 34, so that the magnetic core completely falls into the circular groove 311 and is sleeved outside the brush roller 33. At this time, the driving part 35 drives the turnover block 31 to rotate relative to the rotating shaft 36. Since the rotating shaft 36 is provided with a first bevel gear 361, the brush roller 33 is provided with a second bevel gear 334 matched with the first bevel gear 361, and the brush roller 33 is fixed on the turnover block 31 and rotates relative to the turnover block 31 by matching the limiting ring 333 with the mounting hole 312, therefore, when the turnover block 31 rotates, the brush roller 33 will rotate relative to the turnover block 31 due to the cooperation of the bevel gears. The part of the brush roller 33 with the brush is arranged in the circular groove 311, and the magnetic core is sleeved outside the brush roller 33 at this time, so that the brush roller 33 brushes the burrs in the inner hole of the magnetic core. After the turnover is completed, the annular magnetic attraction device 34 is released, so that the magnetic core falls from the circular groove 311 into the second slide rail 20. Therefore, the magnetic core stamping forming auxiliary equipment completes the overall burr brushing process of the magnetic core in the process of transferring the magnetic core. Therefore, the present application solves the problem of lacking a magnetic core stamping forming auxiliary equipment for removing the burrs of the magnetic core comprehensively in the process of transferring the magnetic core in the prior art.

[0037] It should be noted that the diameter of the brush roller 33 is smaller than the diameter of the inner hole of the magnetic core, so that when the magnetic core is slid by the positioning sliding rail 32 to the circular groove, the magnetic core is in contact with the positioning sliding rail 32 and stops sliding under the sliding action, and the magnetic core is sleeved on the brush roller 33, and the diameter of the circular groove 311 is slightly larger than the diameter of the magnetic core, so that the magnetic core is sunk into the circular groove 311 under the action of gravity, and the magnetic core is fixed in the circular groove 311 by the annular magnetic adsorption device 34, so that the brush roller 33 does not rotate synchronously when rotating, thereby ensuring the cleaning effect of the brush roller 33. In addition, in some optional embodiments, a positioning sensing device can be suspended at the top of the circular groove 311, and the positioning sensing device is used to determine that the magnetic core enters the circular groove 311, and then the turnover cleaning assembly 30 is started. The position of the positioning sensing device does not affect the turnover of the turnover cleaning assembly 30. In addition, the first sliding rail 10 and the second sliding rail 20 can also be annular tracks, which are arranged to slow down the movement speed of the magnetic core on the track, so that when the magnetic core contacts the positioning sliding rail, the collision force is small, preventing the magnetic core from being damaged.

[0038] Specifically, the positioning sliding rail 32 includes a vertical section 321, a transition section 322, and a positioning section 323. The vertical section 321 is aligned with the first sliding rail 10. The cross-sectional area of the transition section 322 gradually decreases from one side close to the first sliding rail 10 to the other side. The positioning section 323 is in the shape of a circular arc and is adapted to the shape of the magnetic core to position the magnetic core and make the magnetic core fall into the circular groove 311. In specific use, the vertical section 321 is aligned with the first sliding rail 10, so that the magnetic core smoothly slides from the first sliding rail 10 into the positioning sliding rail 32. The tapered transition section 322 guides the magnetic core, so that the magnetic core slides to the positioning section 323. The positioning section 323 blocks and positions the magnetic core, so that the magnetic core falls into the circular groove 311. In addition, in specific implementation, there is a gap between the vertical section 321 and the first sliding rail 10, and the size of the gap is smaller than one-fourth of the magnetic core, so that the turnover block 31 does not interfere with the first sliding rail 10 when it turns over, and the magnetic core does not fall from the gap.

[0039] In addition, the diameter of the first bevel gear 361 is greater than that of the second bevel gear 334. By adjusting the diameter and the number of teeth between the first bevel gear 361 and the second bevel gear 334, the transmission ratio between the two can be adjusted, so that when the turnover block 31 rotates 180 degrees relative to the rotating shaft 36, the rotation angle of the brush roller 33 is much greater than 180 degrees, thereby making the burr cleaning effect of the brush roller 33 on the inner hole of the magnetic core better. In addition, a gear set can be additionally provided between the two bevel gears to further increase the transmission ratio between the two. The specific arrangement needs to be adjusted according to the actual cleaning effect, and the gear combination or bevel gear needs to be adjusted to adjust the transmission ratio between the two bevel gears. For example, the new stamping equipment mold has little or no gap, so there are few burrs, and the transmission ratio does not need to be too large. When the stamping equipment is used for a long time, the mold gap is large, and the transmission ratio or the auxiliary equipment with a larger transmission ratio needs to be adjusted to improve the burr cleaning effect of the inner hole of the magnetic core.

[0040] Specifically, the inside of the positioning section 323 is provided with a fixing groove 324, and the fixing groove 324 is provided with a buffer 325. The magnetic core is relatively brittle after being formed by the stamping equipment, and is easy to break or be damaged at the corners under strong impact. Although the inclination angle and length of the slide rail, the number of end surface cleaning devices 40 and side surface cleaning devices 50, and the contact degree of the brushes of each device with the magnetic core can be adjusted to adjust the speed of the magnetic core into the positioning slide rail 32, thereby ensuring that the intensity of the magnetic core when contacting the positioning section 323 of the positioning slide rail 32 is very low to ensure that the magnetic core will not be broken by impact, the buffer 325 is additionally provided to make the adjustment threshold of the slide rail and other cleaning equipment larger and easier to adjust, and the buffer 325 can further ensure the intensity of the contact between the magnetic core and the positioning section 323, and make the magnetic core stay in the circular groove 311 of the positioning section 323 after contacting the positioning section 323, instead of bouncing out of the positioning section 323. In specific implementation, the buffer 325 can be sponge, nylon, rubber, etc. The type with good impact force absorption effect and slow rebound is selected according to the requirement.

[0041] In addition, the end face cleaning device 40 includes a disc brush 41 suspended above the slide rail, and a driving component 35 driving the disc brush 41 to rotate, and a plurality of end face cleaning devices 40 are respectively equidistantly distributed on the first slide rail 10 and the second slide rail 20. Specifically, the burrs on the end face of the magnetic core are cleaned by driving the disc brush 41 to rotate by the driving component 35, and in addition, the height of the disc brush 41 is adjusted as needed, and then the contact degree of the disc brush 41 with the magnetic core is adjusted, and in addition, the number of end face cleaning devices is adjusted according to the burr condition and the moving speed of the magnetic core, so as to ensure the burr cleaning effect of the magnetic core and ensure that the magnetic core can smoothly enter the circular groove 311. It should be noted that the end face of the disc brush 41 is parallel to the first slide rail 10 or the second slide rail 20, so as to ensure the effect of the disc brush 41. In addition, in specific implementation, the driving component 35 can adopt a servo motor, an asynchronous motor or a direct current motor, etc. or other driving mechanisms, which are not limited here.

[0042] Specifically, the side face cleaning device 50 includes a belt brush 51 arranged on the side face of the slide rail, a driven wheel 52 and a driving wheel 53 connected to the inner side of the belt brush 51, and a driving component 35 connected to the driving wheel 52, and the driving component 35 drives the driving wheel 53 to rotate to drive the belt brush 51, and the side face of the slide rail is provided with a accommodating groove 11 matched with the belt brush 51, and a plurality of side face cleaning devices 50 are respectively equidistantly distributed on the first slide rail 10 and the second slide rail 20. The rectangular belt brush 51 is placed on the side face of the slide rail by the two driven wheels 52 to clean the burrs on the side face of the magnetic core. Compared with the disc brush 41 which needs to protrude part of the disc brush 41 to the slide rail to increase the area of the brush, which will affect the movement of the magnetic core, the position of the driven wheel 52 can be adjusted according to the demand, and then the area and shape of the belt brush 51 are adjusted, which is more convenient.

[0043] By way of example, but not limitation, in some optional embodiments, the first slide rail 10 and the second slide rail 20 are respectively provided with symmetrically arranged side face cleaning devices 50 on both sides, and the transmission directions of the belt brushes 51 of the side face cleaning devices 50 on both sides are opposite. By adjusting the transmission direction of the belt brush 51, when the two belt brushes 51 clean the burrs on the side face of the magnetic core, the magnetic core can rotate while moving downward, and then when the magnetic core contacts the belt brush 51 of the next side face cleaning device 50, the burr cleaning effect of the belt brush 51 is better. In addition, the transmission directions of the belt brushes 51 can also be set in the same direction, and by adjusting the transmission direction of the belt brush 51 in the same direction to be consistent or opposite to the moving direction of the magnetic core, the moving speed of the magnetic core in the slide rail can be adjusted, so as to adjust the transfer or cleaning efficiency of the magnetic core, and ensure that the magnetic core can move into the circular groove 311.

[0044] Specifically, the magnetic core stamping forming auxiliary equipment further comprises a support frame 60, a plurality of support frames 60 are arranged above the first slide rail 10 and the second slide rail 20 to support the slide rails, and at least part of the support frames 60 extend outwardly and are provided with support structures for fixing the turnover cleaning brush assembly 30, the end face cleaning brush device 40 and the side face cleaning brush device 50 respectively. By arranging the support frames 60, the first slide rail 10 and the second slide rail 20 can be supported and fixed, and in addition, part of the support frames 60 are also used for fixing the turnover cleaning brush assembly 30, the end face cleaning brush device 40 and the side face cleaning brush device 50.

[0045] In addition, the inclination angle of the second slide rail 20 is greater than that of the first slide rail 10. When the magnetic core enters the first slide rail 10 from the stamping equipment, it is usually pushed into the first slide rail 10 by a pushing mechanism on the stamping equipment, so that the magnetic core has a certain initial speed in the first slide rail 10 and moves at a relatively fast speed. When entering the second slide rail 20, it needs to rely on its own gravity to move in the second slide rail 20, so the inclination angle of the second slide rail 20 needs to be larger to ensure that the magnetic core can move smoothly in the second slide rail 20. In addition, adjusting the inclination angle of the second slide rail 20 relative to the additional pushing assembly for pushing the magnetic core saves the cost of the pushing assembly. In addition, by way of example but not limitation, in some optional embodiments, the second slide rail 20 is provided with an extension near the side close to the first slide rail 10 and is arranged below the first slide rail 10 to receive the cleaned burr waste falling from the gap between the positioning slide rail 32 and the first slide rail 10. In addition, the first slide rail 10 and the second slide rail 20 are composed of multiple segments, and there is a certain gap between adjacent segments to enable the cleaned burr to move out of the slide rail through the gap to prevent the burr from affecting the subsequent movement of the magnetic core. A material collecting box is arranged below the gap for collecting and processing the cleaned burr.

[0046] Specifically, the bottom of the second slide rail 20 is provided with a ring-shaped magnetic attraction device 34 matched with the circular groove 311 for assisting the magnetic core in the circular groove 311 to fall into the second slide rail 20. The ring-shaped magnetic attraction device is also arranged at the bottom of the second slide rail to prevent the magnetic core from falling into the second slide rail 20 by gravity after the ring-shaped magnetic attraction device 34 in the turnover block 31 cancels the attraction. Therefore, the ring-shaped magnetic attraction device 34 at the bottom of the second slide rail 20 assists the magnetic core to fall into the second slide rail 20 from the circular groove 311, and then cancels the attraction, so that the magnetic core moves along the second slide rail 20 under the action of gravity. In addition, in some optional embodiments, water flow can be introduced into the first slide rail 10 and the second slide rail 20 to make the magnetic core more easily move along the slide rail. In addition, the water flow can also roll the cleaned burr in the slide rail into the collecting box to speed up the processing of the burr waste and prevent the burr waste from adhering to the track to affect the magnetic core. In addition, a waste water recycling device can be arranged at the collecting box to collect waste water for recycling.

[0047] In summary, the magnetic core stamping forming auxiliary equipment in the above embodiments of the present application, by setting the end face cleaning brush device 40 and the side face cleaning brush device 50 on the first sliding rail 10, the burr removal of the top end face and the side face of the annular magnetic core formed into the first sliding rail 10 from the stamping equipment, and then the 180-degree turning of the magnetic core into the second sliding rail 20 by the turning cleaning brush assembly 30, so that the end face cleaning brush device 40 and the side face cleaning brush device 50 on the second sliding rail 20 remove the burrs of the bottom end face and the side face of the magnetic core, and in addition, the inner hole of the magnetic core is removed by the turning cleaning brush assembly 30 when the magnetic core is turned. Specifically, when the magnetic core enters the positioning sliding rail 32 from the first sliding rail 10, under the action of the positioning sliding rail 32, the magnetic core partially falls into the circular groove 311, and the magnetic core is adsorbed by the annular magnetic attraction device 34, so that the magnetic core completely falls into the circular groove 311 and is sleeved outside the brush roller 33. At this time, the driving part 35 drives the turning block 31 to rotate relative to the rotating shaft 36. Since the rotating shaft 36 is provided with a first bevel gear 361, the brush roller 33 is provided with a second bevel gear 334 matched with the first bevel gear 361, and the brush roller 33 is fixed on the turning block 31 and rotates relative to the turning block 31 by matching the limiting ring 333 with the mounting hole 312. Therefore, while the turning block 31 rotates, the brush roller 33 rotates relative to the turning block 31 due to the matching of the bevel gears. The part of the brush roller 33 with the brush is arranged in the circular groove 311, and the magnetic core is sleeved outside the brush roller 33 at this time, so that the brush roller 33 brushes the burrs in the inner hole of the magnetic core. After turning, the annular magnetic attraction device 34 releases the adsorption, so that the magnetic core falls into the second sliding rail 20 from the circular groove 311. Therefore, the magnetic core stamping forming auxiliary equipment completes the overall burr brushing process of the magnetic core in the process of transferring the magnetic core. Therefore, the present application solves the problem of lacking a magnetic core stamping forming auxiliary equipment for removing the burrs of the magnetic core comprehensively in the process of transferring the magnetic core in the prior art.
