The magnetic powder heat treatment feeding device of the present invention is provided with a track mechanism, a movable seat, a box body, a drive component, a feeding component, and a scraping component. When the placement chamber is filled with magnetic powder, the scraping component is activated to scrape away the magnetic powder that protrudes from the box body, so that the height of the magnetic powder in multiple placement chambers is the same.

Description

Technical Field

[0001] The invention relates to the field of magnetic powder core processing equipment, in particular to a magnetic powder heat treatment feeding device. Background Art

[0002] Magnetic powder cores are a type of soft magnetic material made by mixing and pressing ferromagnetic powder particles (magnetic powder) with an insulating medium. Because the ferromagnetic particles are very small and separated by a non-magnetic, electrically insulating film, they can isolate eddy currents, making the material suitable for higher frequencies. Furthermore, due to the gap effect between the particles, the material has low and constant magnetic permeability. Furthermore, due to the small particle size, skin effect is essentially non-existent, and the change in magnetic permeability with frequency is relatively stable.

[0003] Before magnetic powder cores are made, magnetic powders typically need to undergo a heat treatment, especially those produced using mechanical powder processing, to eliminate internal stress. During this heat treatment, ensuring uniformity is crucial.

[0004] To ensure uniform heat treatment of magnetic powder, operators typically spread the powder onto a carrier plate before transferring the plate into a heat treatment furnace. However, this method is inefficient and labor-intensive, and the uniformity of the powder's thickness on the plate cannot be effectively guaranteed, resulting in poor heat treatment uniformity.

[0027] Specific embodiments of the present invention are described below with reference to the accompanying drawings.

[0028] Example 1

[0029] like Figure 1 - Figure 3 As shown, a magnetic powder heat treatment feeding device includes a track mechanism 100, a movable seat 200 and a feeding mechanism 300.

[0030] like Figure 1 - Figure 3 As shown, the track mechanism 100 includes two guide rails 101, a first rack 102 and two side plates 103. The first rack 102 is located between the two guide rails 101; the two side plates 103 are fixedly connected to the two ends of the guide rails 101 and the first rack 102 respectively.

[0032] The horizontal plate 211 is rotatably connected to the movable base 200; the box body 230 is fixedly connected to the top surface of the horizontal plate 211, and the box body 230 is provided with a plurality of placement cavities 231 of the same size for containing magnetic powder; a plurality of through slots 212 are all provided on the horizontal plate 211, and the plurality of through slots 212 are all provided on the periphery of the box body 230;

[0033] The first storage slot 201 is provided on the top surface of the movable base 200 ; the semicircular slot 202 is provided on the side surface of the movable base 200 ; the second storage slot 203 is provided on the bottom surface of the movable base 200 , and the driving assembly 240 is installed in the second storage slot 203 .

[0034] Two chute grooves 204 are provided on the bottom surface of the movable base 200 and are slidably connected to the two guide rails 101. A semicircular plate 210 is located within and slidably connected to the semicircular groove 202, and a horizontal plate 211 is fixedly connected to the semicircular plate 210. A first motor 220 is mounted within the first storage groove 201, and the power output shaft of the first motor 220 is fixedly connected to the semicircular plate 210. A second rack 250 is mounted on the bottom surface of the movable base 200.

[0035] The driving assembly 240 is used to drive the mobile seat 200 to move along the track mechanism 100; the driving assembly 240 includes a second motor 241 and a gear 242, the second motor 241 is installed in the second storage slot 203; the gear 242 is fixedly mounted on the power output shaft of the second motor 241, and the gear 242 is meshed with the first rack 102.

[0036] Specifically, when the second motor 241 is running, the power output shaft of the second motor 241 will drive the gear 242 to rotate, and the rotating gear 242 will engage with the first rack 102, thereby driving the movable seat 200 to move along the two guide rails 101, and then driving the box body 230 on the cross plate 211 to move, thereby facilitating the delivery of the box body 230 and the magnetic powder in the box body 230 into the heat treatment equipment, or taking the box body 230 and the magnetic powder in the box body 230 out of the heat treatment equipment.

[0037] After the box body 230 is taken out from the heat treatment equipment, the collection container is placed directly below the box body 230, and then the first motor 220 is started so that the power output shaft of the first motor 220 drives the semicircular plate 210 to rotate, and then drives the horizontal plate 211 and the box body 230 to rotate, and then the magnetic powder in the box body 230 is poured into the collection container.

[0038] like Figure 3 、 Figure 7 - Figure 9 As shown, the feeding mechanism 300 includes a fixing frame 301, a feeding assembly 310, a scraping assembly 320 and a power assembly.

[0039] The fixing frame 301 is C-shaped. The feeding assembly 310 is fixedly connected to the fixing frame 301 and is used to feed magnetic powder into the placement chamber 231. The feeding assembly 310 includes a barrel 311, a feeding pipe 312, a first shaft 313, a plurality of stirring rods 314 and a plurality of electromagnetic valves 316.

[0040] The barrel 311 is installed through the top surface of the fixed frame 301; the feeding tube 312 is installed through the top surface of the barrel 311; the first shaft 313 extends through the top surface of the barrel 311 and is rotatably connected to the barrel 311; multiple stirring rods 314 are fixedly mounted on the portion of the first shaft 313 located within the barrel 311; multiple discharge pipes 315 are installed on the bottom surface of the barrel 311; and multiple solenoid valves 316 are respectively installed on the multiple discharge pipes 315. The power assembly includes a dual-axis motor 341, which is installed on the top surface of the barrel 311. The power output shaft at the bottom of the dual-axis motor 341 is fixedly connected to the first shaft 313.

[0041] Specifically, by activating the dual-axis motor 341, the lower power output shaft of the dual-axis motor 341 drives the first shaft 313 to rotate, which in turn drives the multiple stirring rods 314 to rotate. The rotating stirring rods 314 stir the magnetic powder in the barrel 311 to prevent the magnetic powder from clumping. When the solenoid valve 316 is opened, the magnetic powder in the barrel 311 is discharged through the discharge pipe 315.

[0042] The scraping assembly 320 is used to scrape off any magnetic powder within the chamber 231 that protrudes beyond the housing 230. The scraping assembly 320 includes a third motor 321 and a scraper 322. The third motor 321 is mounted on the bottom surface of the barrel 311. The scraper 322 is mounted on the power output shaft of the third motor 321, with the bottom surface of the scraper 322 contacting the top surface of the housing 230. The third motor 321 is a forward-rotating motor, and the power output shaft of the third motor 321 rotates forward one revolution followed by a reverse revolution.

[0043] Specifically, after the magnetic powder in the cylinder 311 is added into the box body 230, the third motor 321 is started so that the power output shaft of the third motor 321 drives the scraper 322 to rotate. The rotating scraper 322 will scrape away the magnetic powder that is higher than the box body 230, and the scraped magnetic powder will pass through the through slot 212 and fall to the bottom of the horizontal plate 211.

[0044] When using the magnetic powder heat treatment feeding device to place the magnetic powder into the heat treatment equipment: first adjust the position of the horizontal plate 211 so that the box body 230 on the horizontal plate 211 is located directly below the cylinder 311, so that the multiple discharge pipes 315 on the cylinder 311 correspond one to one with the multiple placement cavities 231 on the box body 230.

[0045] Then, by starting the solenoid valves 316 on the multiple placement chambers 231, the magnetic powder in the cylinder 311 is discharged through the multiple discharge pipes 315. The magnetic powder discharged through the discharge pipes 315 will fall into the multiple placement chambers 231 respectively. When the placement chamber 231 is full of magnetic powder, the third motor 321 is started so that the power output shaft of the third motor 321 drives the scraper 322 to rotate. The rotating scraper 322 will scrape away the magnetic powder that is higher than the box body 230, and the scraped magnetic powder will pass through the through slot 212 and fall to the bottom of the horizontal plate 211.

[0046] Then, by starting the second motor 241, the power output shaft of the second motor 241 drives the gear 242 to rotate, and the rotating gear 242 will engage with the first rack 102, thereby driving the movable seat 200 to move along the two guide rails 101, and then driving the box body 230 on the cross plate 211 to move, thereby facilitating the box body 230 and the magnetic powder in the box body 230 to be sent into the heat treatment equipment, and the magnetic powder is heat-treated by the heat treatment equipment to remove the stress of the magnetic powder.

[0047] After the heat treatment is completed, by starting the second motor 241, the second motor 241 drives the gear 242 to rotate in the opposite direction, and then the movable seat 200 moves along the guide rail 101, and then the cross plate 211 and the box body 230 are removed from the heat treatment equipment, and then the collection container is placed directly below the box body 230, and then by starting the first motor 220, the power output shaft of the first motor 220 drives the semicircular plate 210 to rotate, and then drives the cross plate 211 and the box body 230 to rotate, and then the magnetic powder in the box body 230 is poured into the collection container.

[0048] Example 2

[0049] like Figure 1 - Figure 3 and Figure 7 - Figure 9 As shown, while other parts are the same as those in Example 1, the difference between this embodiment and Example 1 is that the feeding mechanism 300 also includes a return material component 330, which is used to collect the magnetic powder discharged through the through groove 212 and transport the magnetic powder into the cylinder 311. The return material component 330 includes a fixed cylinder 331, a second shaft 332, a spiral blade 333, a rotating cylinder 334, a receiving hopper 335, a gear ring 336 and a connecting pipe 337.

[0050] The fixed cylinder 331 passes through the top surface of the fixed frame 301 and is fixedly connected to the fixed frame 301. A feed trough is provided on the side surface of the fixed cylinder 331. The second shaft 332 passes through the top surface of the fixed cylinder 331 and is rotatably connected to the fixed cylinder 331. The spiral blade 333 is installed on the part of the second shaft 332 located inside the fixed cylinder 331. The rotating cylinder 334 is rotatably sleeved on the fixed cylinder 331, and the rotating cylinder 334 covers the feed trough.

[0051] One end of the material receiving hopper 335 is installed on the rotating cylinder 334, and the other end of the material receiving hopper 335 is funnel-shaped. When the upper end of the material receiving hopper 335 is located directly below the box body 230, the material receiving hopper 335 is connected to the feed trough, so that the magnetic powder in the material receiving hopper 335 can enter the interior of the fixed cylinder 331; the gear ring 336 is fixedly mounted on the rotating cylinder 334, and the gear ring 336 is engaged with the second rack 250; one end of the connecting tube 337 is fixedly connected and connected to the fixed cylinder 331, and the other end of the connecting tube 337 is fixedly connected and connected to the cylinder body 311.

[0052] Specifically, when the receiving hopper 335 is located directly below the box body 230, the magnetic powder scraped away by the scraper 322 will fall into the feeding hopper 335 through the through slot 212, and the magnetic powder in the receiving hopper 335 will enter the fixed cylinder 331 through the feeding trough, and then the second shaft 332 will be rotated, thereby driving the spiral blade 333 to rotate. When the spiral blade 333 rotates, the magnetic powder in the fixed cylinder 331 will be transported upward, and then the magnetic powder will enter the cylinder body 311 through the connecting pipe 337, thereby avoiding the loss of magnetic powder.

[0053] like Figure 1 - Figure 3 and Figure 7 - Figure 9 As shown, the power assembly also includes a connecting pipe 337, a second pulley 343, and a transmission belt 344. The first pulley 342 is fixedly mounted on the power output shaft at the upper portion of the dual-shaft motor 341; the second pulley 343 is fixedly mounted on the upper end of the second shaft 332; and the transmission belt 344 is mounted on the first pulley 342 and the second pulley 343.

[0054] Specifically, when the dual-shaft motor 341 is running, the power output shaft on its upper portion drives the first pulley 342 to rotate, and then drives the second pulley 343 to rotate via the transmission belt 344, and then drives the second shaft 332 to rotate.

[0055] Working principle: During specific use, when the receiving hopper 335 is located directly below the box body 230, the magnetic powder scraped away by the scraper 322 will fall into the receiving hopper 335 through the through slot 212, and the magnetic powder in the receiving hopper 335 will enter the fixed cylinder 331 through the feed trough, and then start the dual-axis motor 341, so that the power output shaft on its upper part drives the first pulley 342 to rotate, and then drives the second pulley 343 to rotate through the transmission belt 344, and then drives the second shaft 332 to rotate, and then drives the spiral blade 333 to rotate. When the spiral blade 333 rotates, it will transport the magnetic powder in the fixed cylinder 331 upward, and then make the magnetic powder enter the cylinder 311 through the connecting pipe 337, thereby avoiding the loss of magnetic powder.

[0056] When the box body 230 and the magnetic powder need to be moved into the heat treatment equipment, the power output shaft of the second motor 241 drives the gear 242 to rotate, and the rotating gear 242 engages with the first rack 102, thereby driving the movable base 200 to move along the two guide rails 101, and then drives the second rack 250 to move. When the second rack 250 engages with the gear ring 336, as the movable base 200 continues to move, the second rack 250 drives the gear ring 336 to rotate, and then drives the receiving hopper 335 and the rotating cylinder 334 to rotate, thereby preventing the movable base 200 from colliding with the receiving hopper 335;

[0057] When the box body 230 needs to be moved back to the bottom of the cylinder 311, the power output shaft of the second motor 241 drives the gear 242 to rotate in the opposite direction, and the rotating gear 242 will engage with the first rack 102, thereby driving the movable seat 200 to move along the two guide rails 101, and then driving the second rack 250 to move. When the second rack 250 engages with the gear ring 336, as the movable seat 200 continues to move, the second rack 250 will drive the gear ring 336 to rotate, and then drive the hopper 335 and the rotating cylinder 334 to rotate, so that the hopper 335 is moved back to the bottom of the multiple through slots 212.

[0058] Example 3

[0059] like Figure 1 - Figure 9 As shown, while other parts are the same as those of Example 1, the difference between this embodiment and Example 1 is that the magnetic powder heat treatment feeding device further includes a magnetic powder filling amount monitoring and adjustment unit, and the magnetic powder filling amount monitoring and adjustment unit includes:

[0060] A weight monitoring module, used to monitor the weight of the magnetic powder in each placement cavity 231;

[0061] A pressure monitoring module, used to monitor the pressure in each discharge pipe 315 and the pressure in the cylinder 311;

[0062] The data processing module receives the data from the weight monitoring module and compares it with the preset magnetic powder weight value. Based on the comparison result and the preset algorithm, it calculates the opening time of the solenoid valve 316 and issues a control instruction;

[0063] The control module receives the control instruction sent by the data processing module and controls the opening time of the solenoid valve 316 according to the instruction; when all the solenoid valves 316 are closed, the control module controls the power output shaft of the third motor 321 to rotate one circle.

[0064] Working steps of the magnetic powder filling amount monitoring and adjustment unit:

[0065] Step 1: Confirm the pressure value P1 of the discharge pipe 315 during discharge, and then use the weight monitoring module to monitor the weight value W2 of the magnetic powder in each placement cavity 231, and send the magnetic powder weight value W2 to the data processing module; use the pressure monitoring module to monitor the pressure value P2 in the cylinder 311, and send the pressure value P2 to the data processing module;

[0066] Step 2: The data processing module compares the received multiple magnetic powder weight values ​​W2 with the preset magnetic powder weight value W1 to obtain the magnetic powder weight deviation value W=W2-W1. If the magnetic powder weight deviation value W is greater than the error value, the opening time of the solenoid valve 316 is calculated and a control instruction is issued. The error value can be set by yourself. In this embodiment, the error value is 50g.

[0067] Step 3: The control module controls the opening time of the solenoid valve 316 according to the instruction. After the solenoid valve 316 is opened, the magnetic powder in the cylinder 311 is discharged into the placement chamber 231 through the discharge pipe 315;

[0068] Step 4: After all the solenoid valves 316 are closed, the control module controls the power output shaft of the third motor 321 to rotate one circle, driving the scraper 322 to rotate. The rotating scraper 322 will scrape away the magnetic powder that is higher than the box body 230;

[0069] Step 5: Repeat steps 1 to 4 until the weight deviation values ​​W of the magnetic powder in all the placement cavities 231 are all smaller than the error value;

[0070] The calculation formula for the opening time of the solenoid valve 316 is: T=W / Q;

[0071] Q=C×A×sqrt(2gΔh)×(D^2 / 4)×(1 / L)×sqrt(ΔP / ρ);

[0072] ΔP=P2-P1;

[0073] Wherein, T is the opening time of the solenoid valve 316, W is the magnetic powder weight deviation value W, Q is the flow rate, C is the flow coefficient, A is the cross-sectional area of ​​the discharge pipe 315, g is the acceleration of gravity, Δh is the vertical height difference between the lower end of the discharge pipe 315 and the cylinder 311, D is the diameter of the discharge pipe 315, L is the length of the discharge pipe 315, ΔP is the pressure difference between the cylinder 311 and the discharge pipe 315, and ρ is the density of the magnetic powder.

[0074] The flow coefficient C is obtained by placing magnetic powder of known mass into the cylinder 311, placing a flow meter at the lower end of the discharge pipe 315, and then opening the solenoid valve 316 on the discharge pipe 315 to allow the magnetic powder in the cylinder 311 to begin to flow downward. At the same time, the timer is started, and the flow meter measures the mass of the magnetic powder flowing through the discharge pipe 315. The actual flow rate Q is calculated based on the measured data and compared with the flow rate calculated by the formula. Through multiple experiments and data analysis, the value of C is fitted so that the flow rate calculated by the formula is as close as possible to the actual measured value.

[0075] The magnetic powder filling amount monitoring and adjustment unit provides accurate data by monitoring the weight of the magnetic powder in the placement tank in real time, ensuring precise control of the weight of the magnetic powder in the placement tank, which helps to reduce errors and avoid uneven heating of the magnetic powder in the box body 230 in the heat treatment equipment, thereby facilitating improved product quality.

[0076] The magnetic powder filling amount monitoring and adjustment unit can realize the automatic control of adding magnetic powder into the placement tank, and automatically adjust it according to the monitoring data, reducing manual intervention and operating costs.
