[0002] Ferrite core is made of dense and homogeneous non-metallic magnetic material with ceramic structure and low coercivity, also known as soft ferrite. It is composed of iron oxide and one or more other metal oxides or carbonate compounds. The ferrite raw material is pressed, sintered at 1300 degrees, and finally machined into a finished core that meets the 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.

[0013] Compared with the prior art, the present invention has the following beneficial effects: (1) A grinding mechanism for grinding soft ferrite cores. When the conveying seat drives the connecting slide rail to move the push rod out of the trapezoidal slide rail, two sets of servo electric cylinders are operated to simultaneously push the moving slide block toward the ferrite core, thereby pushing the two sets of fixed shafts toward the ferrite core. When the right fixed shaft moves to a certain position inside the ferrite core, the push block on the left fixed shaft also moves to the inside of the fixed groove and engages with the engaging seat. At this time, the two sets of first grinding rollers are just in contact with the two end surfaces of the ferrite core. During the process of the push block engaging with the engaging seat, The push block will push the positioning slider against the inner wall of the ferrite core, fix the ferrite core in the middle of the two sets of grinding mechanisms, and then when the first servo motor is operated to drive the fixed shaft to rotate, the ferrite core will also be driven to rotate under the action of the positioning slider. When the first driving shaft rotates, under the action of the driving gear, the driven gear and the inner gear disc, the first grinding roller can be rotated in the opposite direction to the ferrite core. The rotation of the first grinding roller in the opposite direction to the ferrite core can achieve more efficient grinding of the end face of the ferrite core. The two sets of first grinding rollers can efficiently grind the ferrite core.

[0014] (2) A grinding mechanism for grinding and producing soft ferrite cores. When grinding the ferrite cores, the conveying seat can carry the ferrite cores and move them to the unloading end of the conveying table, thereby realizing the simultaneous conveying and grinding, which greatly improves the work efficiency. Even when the second servo motor drives the second drive shaft to rotate, the moving gear can rotate. At the same time, under the action of the rack, the conveying seat can transport the ferrite cores being ground or completed to the unloading end. When the second drive shaft rotates, the second grinding roller can be driven to rotate by the action of the transmission belt. By controlling the rotation direction of the first servo motor and the second servo motor, the moving direction of the second grinding roller when the conveying seat transports the material to the unloading end is opposite to the rotation direction of the ferrite core. At this time, the second grinding roller can realize efficient grinding of the circumferential surface of the ferrite core. At the same time, under the action of the grinding mechanism, the ferrite core can be fully ground, thereby improving the grinding quality of the ferrite core.

[0015] (3) This kind of grinding mechanism for grinding soft ferrite cores, when the conveying seat moves to the unloading port of the unloading box, the connecting slide rail will also drive the trapezoidal slide rail to move in the direction of the unloading box, so that the push rod moves to the inside of the trapezoidal slide rail. In the process of the push rod moving to the inside of the trapezoidal slide rail, the trapezoidal slide rail will push the rod to move in the direction of the fixed frame in the third slide rail. At this time, the sliding frame will push the first baffle plate to move in the inside of the unloading box and compress the return spring through the slide plate. When the first baffle plate moves to the inside of the unloading box, the second baffle plate can be moved to the outside of the unloading 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 moves completely to the inside of the trapezoidal slide rail, the second baffle plate will no longer block the ferrite core originally located between the first baffle plate and the second baffle plate, thereby causing it to be unloaded into the conveying seat at the lower end of the unloading port of the unloading box, and the first baffle plate will block the ferrite core originally located in the second position of the unloading box. At this time, the loading of the ferrite core to the conveying seat is completed. After the loading of the conveying seat is completed, it will drive the connecting slide rail to move to the unloading end of the conveying table. At this time, under the action of the reset spring, the first baffle plate and the second baffle plate can be reset, and this method can greatly facilitate the unloading and loading of the ferrite core to be polished.

[0024] It should be noted that when the conveying seat 31 moves to the unloading port of the unloading box 42, the connecting slide rail 21 will also drive the trapezoidal slide rail 218 to move in the direction of the unloading box 42, so that the push rod 416 moves to the inside of the trapezoidal slide rail 218. In the process of the push rod 416 moving to the inside of the trapezoidal slide rail 218, the push rod 416 moves in the third slide rail 417 toward the direction of the fixed frame 41. At this time, the sliding frame 415 will push the first material baffle plate 43 to move into the inside of the unloading box 42 and compress the return spring 413 through the slide plate 414.

When the push rod 416 is completely moved to the inside of the trapezoidal slide rail 218 The second stop plate 44 will no longer stop the ferrite core originally located between the first stop plate 43 and the second stop plate 44, thereby causing it to be discharged into the conveying seat 31 located at the lower end of the discharge port of the discharge box 42, and the first stop plate 43 will stop the ferrite core originally located in the second position of the discharge box 42. At this time, the loading of the ferrite core to the conveying seat 31 is completed. After the loading of the conveying seat 31 is completed, it will drive the connecting slide rail 21 to move toward the discharge end, so that the push rod 416 slowly moves out of the trapezoidal slide rail 218. At this time, under the action of the reset spring 413, the first stop plate 43 and the second stop plate 44 can be reset. At this time, the ferrite core originally located in the second position of the discharge box 42 will become the first position, and the third position will become the second position. This is a cycle. In this way, the unloading and loading of the ferrite core to be polished can be greatly facilitated.

[0025] The working principle and use process of the present invention: When the conveying seat 31 moves to the discharge port of the discharge box 42, the connecting slide rail 21 will also drive the trapezoidal slide rail 218 to move in the direction of the discharge box 42, so that the push rod 416 moves to the inside of the trapezoidal slide rail 218. In the process of the push rod 416 moving to the inside of the trapezoidal slide rail 218, the push rod 416 moves in the third slide rail 417 toward the direction of the fixed frame 41. At this time, the sliding frame 415 will push the first baffle plate 43 to move into the inside of the discharge box 42, and compress the return spring 413 through the slide plate 414. When the first baffle plate 43 moves into the inside of the discharge box 42, the second baffle plate 44 can be moved to the outside of the discharge 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 is completely moved When it reaches the inside of the trapezoidal slide rail 218, the second material blocking plate 44 will no longer block the ferrite core originally located between the first material blocking plate 43 and the second material blocking plate 44, so that it can be discharged into the conveying seat 31 located at the lower end of the discharge port of the discharge box 42, and the first material blocking plate 43 will block the ferrite core originally located in the second position of the discharge box 42. At this time, the loading of the ferrite core to the conveying seat 31 is completed. After the loading of the conveying seat 31 is completed, it will drive the connecting slide rail 21 to move toward the discharge end of the conveying platform 10, so that the push rod 416 slowly moves out of the trapezoidal slide rail 218. At this time, under the action of the reset spring 413, the first material blocking plate 43 and the second material blocking plate 44 can be reset. At this time, the ferrite core originally located in the second position of the discharge box 42 will become the first position, and the third position will become the second position. When the conveying seat 31 drives the connecting slide rail 21 to move the push rod 416 out of the trapezoidal slide rail 218, the two sets of servo electric cylinders 23 are operated, and the moving slider 22 is pushed to move in the direction of the ferrite core, thereby pushing the two sets of fixed shafts 27 to move in 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 to the inside of the fixed groove 28 and engage with the engaging seat 29. At this time, the two sets of first grinding rollers 212 are just in contact with the two end surfaces of the ferrite core. In the process of the push block 217 engaging with the engaging seat 29, the push block 217 will push the positioning slider 211 inside the positioning slide rail 210 toward the inner wall of the ferrite core. When the push block 217 is engaged with the engaging seat 29, the positioning slider 211 will also abut against the inner side wall of the ferrite core, thereby fixing the ferrite core in the middle of the two sets of grinding mechanisms 20. Then, when the first servo motor 25 is operated to drive the fixed shaft 27 to rotate, the ferrite core will also be driven to rotate under the action of the positioning slider 211. When the first driving shaft 26 rotates, under the action of the driving gear 214, the driven gear 216 and the inner gear disc 213, the first grinding roller 212 can rotate in the opposite direction to the ferrite core. The first grinding roller 212 rotates in the opposite direction to the ferrite core to achieve more efficient grinding of the end face of the ferrite core. The two sets of first grinding rollers 212 can grind the ferrite core efficiently. When the ferrite core is being polished, the conveying seat 31 can carry the ferrite core to the unloading end of the conveying table 10, and even when the second servo motor 39 drives the second drive shaft 34 to rotate, the moving gear 35 can be rotated. When the moving gear 35 rotates, under the action of the rack 13, the conveying seat 31 can transport the ferrite core being polished or polished to the unloading end. When the second drive shaft 34 rotates, the grinding shaft 36 can be driven by the action of the transmission belt 38. The first servo motor 25 and the second servo motor 39 are controlled to rotate synchronously, thereby driving the second grinding roller 37 to rotate. By controlling the rotation direction of the first servo motor 25 and the second servo motor 39, the movement direction of the second grinding roller 37 when the conveying seat 31 conveys the material to the unloading end is opposite to the rotation direction of the ferrite core. At this time, the second grinding roller 37 can achieve efficient grinding of the circumferential surface of the ferrite core. At the same time, under the action of the grinding mechanism 20, the ferrite core can be fully ground, thereby improving the grinding quality of the ferrite core.
