They are widely used in traditional fields such as power electronics, communication, computers, medical treatment, and automobiles, and are also often used in emerging fields such as new energy, high-speed trains, and smart homes. With the wide promotion of the application fields of ferrite magnetic cores, the existing manufacturing process mode can no longer meet the production process requirements of products, and precision post-processing must be adopted to meet the product size requirements.

[0031] The ferrite core processing device provided in this embodiment has high working efficiency and can improve the grinding accuracy of the circular core.
[0032] Specifically, as shown in Figure 1 and Figure 2 , the ferrite core processing device includes a frame 100, an outer circle grinding assembly 200, a grooving assembly 300, a track 400, and a fixture assembly 500. The outer circle grinding assembly 200 includes a driving grinding wheel 210 and a driven grinding wheel 220. The driving grinding wheel 210 and the driven grinding wheel 220 are oppositely arranged on the frame 100 and can perform outer circle grinding on the circular core 10. The grooving assembly 300 includes a grooving grinding wheel and is installed on the frame 100 and can perform grooving on the circular core 10. The track 400 is erected on the frame 100, and the fixture assembly 500 is installed on the track 400. The fixture assembly 500 can clamp the circular core 10, and first push the circular core 10 to the grinding area of the outer circle grinding assembly 200 for grinding, and then push the circular core 10 to the grooving area of the grooving assembly 300 for grooving.
[0033] Based on the above design, the ferrite core processing device integrates the operations of rounding and grooving, improving work efficiency. Moreover, the ferrite core processing device first rounds the circular core 10 and then grooves it, avoiding the problem of uneven shape of the circular core 10 caused by grooving in the prior art, and further avoiding the problem of out-of-roundness of the circular core 10 during the rounding operation. That is, the ferrite core processing device enables high-precision rounding of the circular core 10.
[0034] To improve work efficiency and perform batch processing on the circular cores 10, the fixture assembly 500 includes a positioning member 510. The positioning member 510 can fix a plurality of circular cores 10 arranged in a cylinder to form a test piece, and the fixture assembly 500 can clamp the test piece.
[0035] Furthermore, due to the specific shape (ring shape) of the circular core 10, the positioning member 510 passes through and connects a plurality of circular cores 10, and the fixture assembly 500 can clamp both ends of the positioning member 510. This connection method is simple, the positioning member 510 does not block the processing part of the circular core 10, and clamping both ends of the positioning member 510 by the fixture assembly 500 makes the test piece move more smoothly.
[0036] In some embodiments, the positioning member 510 includes a positioning rod and a positioning ring. The positioning rod is fixedly passed through the positioning ring, and the outer wall of the positioning ring is connected to the inner wall of the circular core 10. The fixture assembly 500 can clamp both ends of the positioning rod.
[0037] Continue as Figure 1 and Figure 2As shown, the fixture assembly 500 further includes a driving member 520 and a gripper 530. The driving member 520 is connected to the rail 400 and can reciprocate above the grinding area and above the grooving area. That is, the driving member 520 first drives the test piece to move above the feeding area to above the grinding area, then drives the test piece to above the grooving area, and then returns above the feeding area to grasp the test piece, repeating the above actions. The output end of the driving member 520 is connected to the gripper 530 and can drive the gripper 530 to grasp the test piece. Specifically, the driving member 520 drives the gripper 530 to move downward above the feeding area to the feeding area to make the gripper 530 grasp the test piece; then the driving member 520 drives the gripper 530 with the test piece upward to return above the feeding area. The driving member 520 that moves above the grinding area first drives the gripper 530 with the test piece downward into the grinding area to make the gripper 530 release the test piece; after the gripper 530 releases the test piece, the driving member 520 drives the gripper 530 upward to return above the grinding area; after waiting for the test piece to be processed, the driving member 520 drives the gripper 530 downward to the grinding area to make the gripper 530 grasp the test piece; then the driving member 520 drives the gripper 530 with the test piece upward to return above the grinding area. The driving member 520 that moves above the grooving area first drives the gripper 530 with the test piece downward into the grooving area to make the gripper 530 release the test piece; after the gripper 530 releases the test piece, the driving member 520 drives the gripper 530 upward to return above the grooving area; after waiting for the test piece to be processed, the driving member 520 drives the gripper 530 downward to the grooving area to make the gripper 530 grasp the test piece; then the driving member 520 drives the gripper 530 with the test piece upward to return above the grooving area. The driving member 520 that moves above the discharging area drives the gripper 530 with the test piece downward into the discharging area to make the gripper 530 release the test piece, and then drives the gripper 530 upward to return above the discharging area.
[0038] It should be noted that Figure 1 the three driving members 520 shown on the rail 400 are the same driving member 520, only for the convenience of those skilled in the art to understand that the driving member 520 can respectively move above the feeding area, above the grinding area, and above the grooving area, etc.
[0039] In this embodiment, the driving member 520 is a rodless cylinder, and the rodless cylinder drives the gripper 530 to move towards or away from the grinding area or the grooving area. Of course, in other embodiments, other driving methods may also be used, and the present application does not list them one by one here.
[0040] Continue as Figure 1As shown, the movement of the driving member 520 on the track 400 can be achieved by means of a slide rail sliding method or a conveyor belt method. In this embodiment, the track 400 is a conveyor belt and is located above the grinding area and the grooving area. The conveyor belt drives the driving member 520 to reciprocate above between the grinding area and the grooving area.
[0041] The ferrite core processing device further includes a loading bin 600. The test piece is located in the loading bin 600. A crawler is provided in the loading bin 600, and the crawler can advance intermittently, so that the test pieces are sequentially clamped by the fixture assembly 500.
[0042] In this embodiment, a limiting card slot is provided in the loading bin 600, and the test pieces are sequentially placed into the limiting card slot.
[0043] The ferrite core processing device further includes an unloading bin 700 for placing the processed test pieces.
[0044] In this embodiment, the unloading bin 700 is inclined, so that the processed test pieces are sequentially arranged along the slope of the unloading bin 700, and the test pieces roll down the slope by their own gravity, saving power and reducing costs.
[0045] Continue as Figure 1 As shown, the ferrite core processing device further includes a first motor, a second motor, a third motor, a fourth motor and a fifth motor, all of which are located on the frame 100. The first motor is used to drive the active grinding wheel 210 to move in a direction perpendicular to the plane of the active grinding wheel 210, and adjust the position of the active grinding wheel 210 relative to the driven grinding wheel 220 in a direction perpendicular to the plane of the active grinding wheel 210. The second motor is used to drive the driven grinding wheel 220 to move and change the angle to control the falling angle and grinding position of the circular core 10. The third motor is used to drive the driven grinding wheel 220 to move in a direction parallel to the plane of the active grinding wheel 210, and adjust the position of the driven grinding wheel 220 relative to the active grinding wheel 210 in a direction parallel to the plane of the active grinding wheel 210 to control the size of the circular core 10. The fourth motor is used to drive the active grinding wheel 210 to rotate and drive the driven grinding wheel 220 to perform grinding processing on the circular core 10. The fifth motor is used to drive the grooving grinding wheel to rotate and perform grooving processing on the circular core 10.
[0046] It should be noted that the ferrite core processing device further includes a fine-tuning assembly 800. After the first motor, the second motor and the third motor complete the adjustment of the active grinding wheel 210 or the driven grinding wheel 220, the fine-tuning assembly 800 is used to finely adjust the position of the driven grinding wheel 220 relative to the active grinding wheel 210 in a direction parallel to the plane of the active grinding wheel 210, further improving the processing accuracy of the circular core 10.
