Description

Technical Field

[0001] The present invention relates to the technical field of soft ferrite cores, in particular to a grinding device and method for processing soft ferrite cores. Background Art

[0002] Ferrite cores are made of dense, homogeneous, ceramic-structured non-metallic magnetic materials with low coercivity. They are also called soft ferrites and consist of iron oxide and one or more other metal oxides or carbonate compounds. The ferrite raw material is pressed, sintered at 1300 degrees Celsius, and finally machined into finished cores that meet application requirements. Compared to other types of magnetic materials, ferrites have the advantages of high magnetic permeability, high resistance over a wide frequency range, and low eddy current losses. These material properties make ferrites ideal for high-frequency transformers, broadband transformers, adjustable inductors, and other high-frequency circuits ranging from 10kHz to 50MHz.

[0003] During processing, each surface of the soft ferrite core needs to be ground to ensure the stability of magnetism and performance. Traditional grinding devices need to flip the soft ferrite core during the grinding process, which reduces the grinding efficiency. The fine debris and powdery materials generated during the grinding process are easy to remain and accumulate in the grinding processing area, affecting the quality of the finished product. Therefore, we proposed a grinding device for soft ferrite core processing. Summary of the Invention

[0035] Example 1

[0036] See also Figures 1 to 7 As shown, a grinding device for processing soft ferrite cores includes a feed frame 1, a processing base frame 2, a processing top frame 3 and a discharge frame 4. The top of the processing base frame 2 is fixedly provided with a processing top frame 3, and the left and right sides of the processing base frame 2 are respectively provided with a feed frame 1 and a discharge frame 4. A sealing frame 5 is movably provided inside the processing top frame 3. First servo electric cylinders 6 are fixedly provided on all four sides of the top of the processing top frame 3, and the driving ends of the four first servo electric cylinders 6 are fixedly connected to the top of the sealing frame 5. Grinding mechanisms are provided inside the processing base frame 2 and the sealing frame 5. The surface of the soft ferrite core is fully ground by two grinding mechanisms symmetrically arranged above and below, and there is no need to manually turn the soft ferrite core over, which significantly improves the grinding efficiency of the soft ferrite core. The use of fully automated grinding can improve the consistency and stability of grinding, reduce human errors, and improve production efficiency. When grinding the soft ferrite core using two symmetrically arranged upper and lower grinding mechanisms, the grinding fluid is first sprayed to maintain sufficient cooling during the grinding process, thereby avoiding damage to the core performance caused by overheating. In addition, the grinding debris generated during the grinding process can be washed away by the grinding fluid to avoid the grinding debris being adsorbed on the soft ferrite core and affecting the grinding effect. Then, hot air is blown onto the surface of the soft ferrite core to clean the grinding debris on the surface of the soft ferrite core, while also drying and cleaning the soft ferrite core, ensuring that the surface of the soft ferrite core is clean after grinding, thereby improving the environmental friendliness of the soft ferrite core grinding device.

[0037] Both sides of the bottom of the processing top frame 3 are provided with material picking components, and the automatic loading and unloading operations of the soft ferrite cores are realized by the two material picking components. The soft ferrite cores on the feeding rack 1 are transferred to the inside of the processing base frame 2 by using the material picking component on the right, and the soft ferrite cores inside the processing base frame 2 are transferred to the discharge rack 4 by using the material picking component on the left, thereby realizing the fully automatic grinding processing operation of the soft ferrite cores, reducing manual operation, and improving the production and processing efficiency of the soft ferrite cores.

The position of the soft ferrite core on the first electromagnetic disk 8 is corrected by using the processing components inside the grinding racks 7 on both sides of the processing chamber 9 to ensure that the soft ferrite core is in the center of the first electromagnetic disk 8. Then, the first electromagnetic disk 8 is used to stably adsorb and position the bottom of the soft ferrite core, and the first electromagnetic disk 8 is used to fix the bottom of the soft ferrite core. The driving end of the servo electric cylinder 6 controls the sealing frame 5 to move downward, and the bottom of the sealing frame 5 is sealed with the top of the processing chassis 2 to prevent the debris generated by the soft ferrite core from splashing out during the grinding process, thereby improving the environmental protection of the grinding device. First, the bottom of the soft ferrite core is positioned by the first electromagnetic disk 8 inside the processing chamber 9, and the driving end of the second servo electric cylinder 11 below is used to control the first electromagnetic disk 8 to lift upward, and cooperate with the processing components inside the two grinding frames 7 in the sealing frame 5 to grind the upper surface and the outer peripheral surface of the soft ferrite core. Then, the sealing frame 5 is used to grind the upper surface and the outer peripheral surface of the soft ferrite core. The first electromagnetic disk 8 adsorbs and positions the upper end surface of the soft ferrite core, and the upper first electromagnetic disk 8 is used to drive the soft ferrite core to descend into the interior of the processing chamber 9, and the processing components inside the two grinding racks 7 in the processing chamber 9 are used to grind the lower surface and the outer peripheral surface of the soft ferrite core. At this point, the comprehensive grinding processing of the upper and lower surfaces and the outer peripheral surface of the soft ferrite core is completed. Finally, the upper surface and the outer peripheral surface of the soft ferrite core are blown dry by the upper processing component, and then the lower surface and the outer peripheral surface of the soft ferrite core are blown dry by the lower processing component. After the grinding process of the soft ferrite core is completed, the sealing frame 5 is lifted upwards by controlling the driving end of the first servo electric cylinder 6, and the soft ferrite core in the processing chamber 9 is transferred to the discharging frame 4 for discharging in cooperation with the material taking component on the left, and then the soft ferrite core to be processed is sent into the processing chamber 9 for further grinding process by the material taking component on the right. The surface of the soft ferrite core is fully automated through the grinding mechanism arranged in the sealing frame 5 and the processing chamber 9, and the surface of the soft ferrite core after processing is clean and dry, thereby improving the environmental protection of the grinding device.
