Description

Technical Field

[0001] The present invention belongs to the technical field of soft ferrite cores, and particularly relates to a grinding mechanism for the grinding production of soft ferrite cores. Background Art

[0002] Ferrite cores are made of dense and homogeneous ceramic-structured non-metallic magnetic materials, with low coercivity, also known as soft ferrite cores. They are composed of iron oxide and one or several other metal oxides or carbonate compounds. The ferrite raw materials are pressed and then sintered at a high temperature of 1300 degrees Celsius, and finally processed by machines to make finished cores that meet application requirements. Compared with other types of magnetic materials, the advantages of ferrite are high magnetic permeability, high resistance, and low eddy current loss in a wide frequency range. These material properties make ferrite an ideal material for manufacturing high-frequency transformers, broadband transformers, adjustable inductors, and other high-frequency circuits from 10 kHz to 50 MHz.

[0003] The existing equipment for grinding soft ferrite cores has low grinding efficiency and is difficult to comprehensively grind soft ferrite cores. Therefore, we propose a grinding mechanism for the grinding production of soft ferrite cores. Summary of the Invention

[0013] Compared with the prior art, the beneficial effects of the present invention are:

[0014] (1) For the grinding mechanism used in the production of soft ferrite magnetic cores, when the conveying seat drives the connecting slide rail and the push rod moves out of the trapezoidal slide rail, by operating two servo electric cylinders, they simultaneously push the moving slider towards the direction of the ferrite magnetic core, and then push the two fixed shafts towards the ferrite magnetic core. When the right fixed shaft moves to a certain position inside the ferrite magnetic core, the push block on the left fixed shaft will also move into the fixed slot and engage with the engaging seat. At this time, the two first grinding rollers just fit against the two end surfaces of the ferrite magnetic core. During the engagement process of the push block and the engaging seat, the push block will push the positioning slider against the inner wall of the ferrite magnetic core, fixing the ferrite magnetic core in the middle of the two grinding mechanisms. Then, when the first servo motor operates to drive the fixed shaft to rotate, under the action of the positioning slider, the ferrite magnetic core will also rotate. When the first drive shaft rotates, under the action of the driving gear, driven gear, and internal gear disc, the first grinding roller can rotate in the direction opposite to that of the ferrite magnetic core. The rotation of the first grinding roller in the direction opposite to that of the ferrite magnetic core can achieve more efficient grinding of the end face of the ferrite magnetic core, and the two first grinding rollers can efficiently grind the ferrite magnetic core.

[0015] (2) For the grinding mechanism used in the production of soft ferrite magnetic cores, when grinding the ferrite magnetic core, the conveying seat can carry the ferrite magnetic core and move it towards the discharging end of the conveying table, thus greatly improving the work efficiency by combining conveying and grinding. When the second servo motor operates to drive the second drive shaft to rotate, the moving gear can rotate. At the same time, under the action of the tooth rail, the conveying seat can convey the ferrite magnetic core being ground or already ground to the discharging end. When the second drive shaft rotates, it can drive the second grinding roller to rotate through the action of the transmission belt. By controlling the rotation directions of the first servo motor and the second servo motor, the rotation direction of the second grinding roller is opposite to the moving direction of the ferrite magnetic core when the conveying seat conveys the material to the discharging end. At this time, the second grinding roller can efficiently grind the circumferential surface of the ferrite magnetic core, and at the same time, under the action of the grinding mechanism, it can achieve comprehensive grinding of the ferrite magnetic core, thereby improving the grinding quality of the ferrite magnetic core.

[0016] (3) For the grinding mechanism used in the production of soft ferrite magnetic cores, when the conveying seat moves to the discharge opening of the blanking box, the connecting slide rail will also drive the trapezoidal slide rail to move towards the blanking box, causing the push rod to move into the trapezoidal slide rail. During the process of the push rod moving into the trapezoidal slide rail, the trapezoidal slide rail will push the push rod to move towards the fixed frame within the third slide rail. At this time, the sliding frame will push the first baffle plate into the blanking box and compress the return spring through the sliding plate. When the first baffle plate moves into the blanking box, the second baffle plate can be moved out of the blanking box through the action of the first hinge seat, the first connecting hinge rod, the second hinge seat, the second connecting hinge rod, and the hinge rod. When the push rod completely moves into the trapezoidal slide rail, the second baffle plate will no longer block the ferrite magnetic core originally located between the first baffle plate and the second baffle plate, and thus it will be discharged into the conveying seat located at the lower end of the discharge opening of the blanking box. And the first baffle plate will block the ferrite magnetic core originally scheduled for the second discharge in the blanking box. At this time, the loading of the ferrite magnetic core onto the conveying seat is completed. After the conveying seat finishes loading, it will drive the connecting slide rail to move towards the discharge end of the conveyor table. At this time, under the action of the return spring, the first baffle plate and the second baffle plate can be reset. In this way, it is greatly convenient for the feeding and loading of the ferrite magnetic core to be ground. Description of the Drawings

Specific embodiments

[0032] 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.

[0033] Please refer to Figure 1 - Figure 12, the present invention provides a grinding mechanism for the production of soft magnetic ferrite cores, including a conveying table 10. On both sides of the upper surface of the conveying table 10, there are first slide rails 11. In the middle of the upper surface of the conveying table 10, there is a second slide rail 12. Inside the second slide rail 12, there is a toothed rail 13. Inside the first slide rail 11, there is a grinding mechanism 20 slidably connected. Inside the second slide rail 12, there is a conveying mechanism 30 slidably connected. On the upper surface of the conveying table 10, there is a blanking mechanism 40. The grinding mechanism 20 includes a connecting slide rail 21, which is slidably connected to the first slide rail 11. Inside the connecting slide rail 21, there is a moving slider 22 slidably connected. On the side of the connecting slide rail 21, there is a servo electric cylinder 23, and the output end of the servo electric cylinder 23 is connected to the moving slider 22. On the upper surface of the moving slider 22, there is a rotating seat 24. Inside the rotating seat 24, there is a first driving shaft 26 rotatably connected. On the side of the left rotating seat 24, there is a first servo motor 25, and the output end of the first servo motor 25 is drivingly connected to the first driving shaft 26. One end of the first driving shaft 26 away from the rotating seat 24 is drivingly connected to a fixed shaft 27. Inside one end of the fixed shaft 27 away from the first driving shaft 26, there is a fixed groove 28. On the inner side wall of the fixed groove 28, there is a clamping seat 29. On the circumferential inner surface of the fixed groove 28, there is a positioning slide rail 210. Inside the positioning slide rail 210, there is a positioning slider 211 slidably connected, and the positioning slider 211 is slidably connected to the fixed groove 28. Among them, between the positioning slider 211 and the positioning slide rail 210, there is a reset elastic member. The function of the reset elastic member can make the initial position of the positioning slider 211 inside the fixed groove 28, and without being affected by external forces, it can always be in the initial position. On the circumferential surface of the fixed shaft 27, there is a first grinding roller 212 rotatably connected, and the first grinding roller 212 is rotatably connected to the rotating seat 24. On the inner side wall of the first grinding roller 212, there is an internal gear disk 213. On the circumferential surface of the first driving shaft 26, there is a driving gear 214. On the circumferential surface of the driving gear 214, there is a driven gear 216 meshingly connected, and the driven gear 216 is meshingly connected to the internal gear disk 213. In the middle of the driven gear 216, there is a connecting rotating shaft 215, and the connecting rotating shaft 215 is rotatably connected to the rotating seat 24. There are two groups of grinding mechanisms 20. On one end of the right fixed shaft 27 away from the rotating seat 24, there is a push block 217. Among them, the length of the left fixed shaft 27 is longer than the length of the right fixed shaft 27.

[0034] It should be noted that when the soft ferrite core needs to be polished, the ferrite core is placed in the middle of the two polishing mechanisms 20. Then, by operating the two servo cylinders 23, the moving sliders 22 are simultaneously pushed to move towards the ferrite core, and further the two fixed shafts 27 are pushed to move towards the ferrite core. When the right fixed shaft 27 moves to a certain position inside the ferrite core, the push block 217 on the left fixed shaft 27 will also move into the fixed slot 28 and engage with the engaging seat 29. At this time, the two first grinding rollers 212 just fit against the two end surfaces of the ferrite core. During the engagement of the push block 217 and the engaging seat 29, the push block 217 will push the positioning slider 211 to move towards the inner wall of the ferrite core inside the positioning slide rail 210. When the push block 217 engages with the engaging seat 29, the positioning slider 211 will also abut against the inner wall of the ferrite core, thereby fixing the ferrite core in the middle of the two polishing mechanisms 20. Then, the first servo motor 25 is operated to drive the right first drive shaft 26 to rotate. The right first drive shaft 26 can drive the right fixed shaft 27 to rotate. Since the left fixed shaft 27 and the right fixed shaft 27 are engaged through the push block 217 and the engaging seat 29, the two polishing mechanisms 20 will work simultaneously. When the fixed shaft 27 rotates, under the action of the positioning slider 211, the ferrite core will also be driven to rotate. When the first drive shaft 26 rotates, under the action of the driving gear 214, the driven gear 216 and the internal gear disc 213, the first grinding roller 212 can rotate in the direction opposite to that of the ferrite core. The rotation of the first grinding roller 212 in the direction opposite to that of the ferrite core can achieve more efficient polishing of the end face of the ferrite core. The two first grinding rollers 212 can efficiently polish both ends of the ferrite core.

[0035] The conveying mechanism 30 includes a conveying base 31, and the conveying base 31 is slidably connected to the second slide rail 12. A first limiting roller 32 is rotatably connected inside the conveying base 31, and two groups of first limiting rollers 32 are symmetrically arranged. A second limiting roller 33 is rotatably connected inside the conveying base 31, and two groups of second limiting rollers 33 are symmetrically arranged and are located below the first limiting rollers 32. A second driving shaft 34 is rotatably connected inside the conveying base 31. A moving gear 35 is provided on the circumferential surface of the second driving shaft 34, and the moving gear 35 is meshed with the toothed rail 13. A grinding shaft 36 is rotatably connected inside the conveying base 31. A second grinding roller 37 is provided on the circumferential surface of the grinding shaft 36. When a ferrite core is installed inside the conveying base 31, the second grinding roller 37 will contact the circumferential surface of the ferrite core. A transmission belt 38 is connected between the grinding shaft 36 and the second driving shaft 34. A second servo motor 39 is provided on the side of the conveying base 31, and the second servo motor 39 is connected to the second driving shaft 34 in a transmission manner. A dust shield 310 is provided inside the conveying base 31, and two groups of dust shields 310 are symmetrically arranged. A vacuum cleaner 311 is provided on the side of the conveying base 31. The suction port of the vacuum cleaner 311 is communicated with the space formed between the dust shield 310 and the inside of the conveying base 31. A connecting rod 219 is provided between the conveying base 31 and the connecting slide rail 21. By using the connecting rod 219, when the conveying base 31 moves, it can also drive the connecting slide rail 21 to move synchronously with the conveying base 31 inside the first slide rail 11.

[0036] It should be noted that the inside of the conveying base 31 can carry a ferrite core. When the second servo motor 39 works to drive the second driving shaft 34 to rotate, the moving gear 35 can be rotated. When the moving gear 35 rotates, under the action of the toothed rail 13, the conveying base 31 can convey the ferrite core being polished or polished to the blanking end. When the second driving shaft 34 rotates, the grinding shaft 36 can be driven to rotate synchronously through the action of the transmission belt 38, and then the second grinding roller 37 can be driven to rotate. By controlling the rotation directions of the first servo motor 25 and the second servo motor 39, the rotation direction of the second grinding roller 37 is opposite to the moving direction of the ferrite core when the conveying base 31 conveys the material to the blanking end. At this time, the second grinding roller 37 can efficiently polish the circumferential surface of the ferrite core. At the same time, under the action of the polishing mechanism 20, the ferrite core can be polished comprehensively, thereby improving the polishing quality of the ferrite core.

[0037] The blanking mechanism 40 includes a fixed frame 41, and the fixed frame 41 is arranged on the upper surface of the conveying table 10. A blanking box 42 is provided on the side of the fixed frame 41. A first baffle plate 43 is slidably connected inside the blanking box 42, and a second baffle plate 44 is slidably connected inside the blanking box 42. The second baffle plate 44 is arranged near the outlet of the blanking box 42, and the space between the first baffle plate 43 and the second baffle plate 44 can exactly accommodate one ferrite magnetic core. A first hinge seat 47 is provided on the lower surface of the first baffle plate 43, and a first connecting hinge rod 48 is hinged inside the first hinge seat 47. A second hinge seat 49 is provided on the upper surface of the second baffle plate 44, and a second connecting hinge rod 410 is hinged inside the second hinge seat 49. An articulated rod 46 is hinged between the first connecting hinge rod 48 and the second connecting hinge rod 410. An articulated plate 45 is hinged in the middle of the articulated rod 46, and the articulated plate 45 is connected to the side of the blanking box 42. A support plate 411 is provided on the side of the blanking box 42. A sliding rod 412 is provided between the support plate 411 and the blanking box 42. A sliding plate 414 is provided on the upper surface of the first baffle plate 43, and the sliding plate 414 is slidably connected to the sliding rod 412. A return spring 413 is provided between the sliding plate 414 and the blanking box 42. A sliding frame 415 is provided on the side of the first baffle plate 43. A third slide rail 417 is provided on the upper surface of the conveying table 10, and one end of the sliding frame 415 away from the first baffle plate 43 is slidably connected to the third slide rail 417. A push rod 416 is provided on the side of the sliding frame 415. A trapezoidal slide rail 218 is provided on the side of the left connecting slide rail 21, and the push rod 416 can slide inside the trapezoidal slide rail 218. A stable slide rod 418 is provided on the side of the sliding frame 415. A stable slide rail 419 is provided on the side of the fixed frame 41, and the stable slide rod 418 is slidably located inside the stable slide rail 419.

[0038] It should be noted that when the conveying seat 31 moves to the discharging opening of the discharging box 42, the connecting slide rail 21 will also drive the trapezoidal slide rail 218 to move towards the discharging box 42, so that the push rod 416 moves into the trapezoidal slide rail 218. During the process of the push rod 416 moving into the trapezoidal slide rail 218, the push rod 416 moves towards the fixing frame 41 in the third slide rail 417. At this time, the sliding frame 415 will push the first baffle plate 43 to move into the discharging box 42 and compress the return spring 413 through the sliding plate 414. When the first baffle plate 43 moves into the discharging box 42, the second baffle plate 44 can be moved out of the discharging box 42 through the action of the first hinge seat 47, the first connecting hinge rod 48, the second hinge seat 49, the second connecting hinge rod 410 and the hinge rod 46. When the push rod 416 completely moves into the trapezoidal slide rail 218, the second baffle plate 44 will no longer block the ferrite core originally located between the first baffle plate 43 and the second baffle plate 44, so that it can be discharged into the conveying seat 31 at the lower end of the discharging opening of the discharging box 42. And the first baffle plate 43 will block the ferrite core originally for the second-order discharging in the discharging box 42. At this time, the loading of the ferrite core by the conveying seat 31 is completed. After the conveying seat 31 finishes loading, it will drive the connecting slide rail 21 to move towards the discharging end, so that the push rod 416 slowly moves out of the trapezoidal slide rail 218. At this time, under the action of the return spring 413, the first baffle plate 43 and the second baffle plate 44 can be reset. At this time, the ferrite core originally for the second-order discharging in the discharging box 42 will become the first order, and the third order will become the second order. This is a cycle. By this way, it can greatly facilitate the discharging and loading of the ferrite core to be polished.

[0039] Working principle and usage process of the present invention:

[0040] When the conveying seat 31 moves to the discharging opening of the discharging box 42, the connecting slide rail 21 will also drive the trapezoidal slide rail 218 to move towards the discharging box 42, causing the push rod 416 to move into the trapezoidal slide rail 218. During the process of the push rod 416 moving into the trapezoidal slide rail 218, the push rod 416 moves towards the fixed frame 41 within the third slide rail 417. At this time, the sliding frame 415 will push the first baffle plate 43 to move into the discharging box 42 and compress the return spring 413 through the sliding plate 414. When the first baffle plate 43 moves into the discharging box 42, the second baffle plate 44 can be moved out of the discharging box 42 through the actions of the first hinge seat 47, the first connecting hinge rod 48, the second hinge seat 49, the second connecting hinge rod 410, and the hinge rod 46. When the push rod 416 completely moves into the trapezoidal slide rail 218, the second baffle plate 44 will no longer block the ferrite core originally located between the first baffle plate 43 and the second baffle plate 44, thereby enabling it to be discharged into the conveying seat 31 at the lower end of the discharging opening of the discharging box 42. And the first baffle plate 43 will block the ferrite core originally for second-sequence discharging in the discharging box 42. At this time, the loading of the ferrite core onto the conveying seat 31 is completed. After the conveying seat 31 finishes loading, it will drive the connecting slide rail 21 to move towards the discharging end of the conveying table 10, causing the push rod 416 to slowly move out of the trapezoidal slide rail 218. At this time, under the action of the return spring 413, the first baffle plate 43 and the second baffle plate 44 can be reset. At this time, the ferrite core originally for second-sequence discharging in the discharging box 42 will become the first sequence, and the third sequence will become the second sequence;

[0041] When the conveying seat 31 drives the connecting slide rail 21 and makes the push rod 416 move out of the trapezoidal slide rail 218, by operating the two groups of servo electric cylinders 23, the moving slider 22 is pushed to move towards the direction of the ferrite core, and then the two fixed shafts 27 are pushed to move towards the direction of the ferrite core. When the right fixed shaft 27 moves to a certain position inside the ferrite core, the push block 217 on the left fixed shaft 27 will also move into the fixing groove 28 and engage with the engaging seat 29. At this time, the two first grinding rollers 212 just fit on the end surfaces of both ends of the ferrite core. During the engagement of the push block 217 and the engaging seat 29, the push block 217 will push the positioning slider 211 to move towards the inner wall of the ferrite core inside the positioning slide rail 210. When the push block 217 engages with the engaging seat 29, the positioning slider 211 will also abut against the inner wall of the ferrite core, and thus the ferrite core can be fixed in the middle of the two grinding mechanisms 20. Then, when the first servo motor 25 works to drive the fixed shaft 27 to rotate, under the action of the positioning slider 211, the ferrite core will also be driven to rotate. When the first driving shaft 26 rotates, under the action of the driving gear 214, the driven gear 216 and the internal gear disc 213, the first grinding roller 212 can rotate in the direction opposite to that of the ferrite core. The rotation of the first grinding roller 212 in the direction opposite to that of the ferrite core can achieve more efficient grinding of the end surface of the ferrite core, and the two first grinding rollers 212 can both perform efficient grinding on the ferrite core;

[0042] When grinding the ferrite core, the conveying seat 31 can carry the ferrite core and move it towards the discharging end of the conveying table 10. That is, when the second servo motor 39 works to drive the second driving shaft 34 to rotate, the moving gear 35 can be rotated. When the moving gear 35 rotates, under the action of the tooth rail 13, the conveying seat 31 can convey the ferrite core being ground or having been ground to the discharging end. When the second driving shaft 34 rotates, through the action of the transmission belt 38, the grinding shaft 36 can be driven to rotate synchronously, and then the second grinding roller 37 can be driven to rotate. By controlling the rotation directions of the first servo motor 25 and the second servo motor 39, the rotation direction of the second grinding roller 37 is opposite to the moving direction of the ferrite core when the conveying seat 31 conveys the material to the discharging end. At this time, the second grinding roller 37 can achieve efficient grinding of the circumferential surface of the ferrite core, and at the same time, under the action of the grinding mechanism 20, comprehensive grinding of the ferrite core can be realized, thereby improving the grinding quality of the ferrite core.

The scope of the present invention is defined by the appended claims and their equivalents.
