Description
Technical Field
[0001] This utility model relates to an intelligent loading and unloading magnetic core grinding machine, and in particular to an intelligent loading and unloading magnetic core grinding machine, belonging to the field of magnetic core grinding technology. Background Technology
[0002] Magnetic cores, as key components of inductors, transformers, and filters in electronic devices, are widely used in new energy vehicles, 5G communication equipment, smart homes, and industrial control. Their surface flatness and dimensional accuracy directly determine the permeability, loss rate, and stability of electronic components. For example, in high-frequency communication scenarios, a surface roughness exceeding 0.8μm can increase signal transmission loss by more than 15%; for power supply inductors, a dimensional deviation exceeding ±0.5mm can easily lead to magnetic circuit saturation, affecting the stability of the power supply. Therefore, the grinding process is a crucial step in ensuring the precision and performance of magnetic cores during manufacturing.
[0003] Traditional magnetic core grinding machines require 1-2 operators to be on duty throughout the process. The magnetic cores to be ground are placed one by one on the fixture of the machine's worktable by hand. After grinding, they are removed manually and the qualified and defective products are sorted. However, manual positioning relies on visual observation and manual operation, which makes it difficult to ensure the fit between the magnetic core and the fixture reference surface. Different operators have different operating habits and force, and even the same person's operating accuracy will fluctuate at different times. This results in a large range of accuracy deviations for the same batch of magnetic cores, with a pass rate of only 85%-90%. A large number of products need to be reworked or scrapped. In addition, manual operation has an unavoidable fatigue period. As the working time increases, the speed of picking up and placing magnetic cores will gradually decrease, and rest time needs to be reserved, which further reduces the effective daily production capacity.
[0004] Therefore, there is an urgent need to improve a magnetic core grinding machine tool with intelligent loading and unloading to solve the above-mentioned problems. Utility Model Content

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.
[0017] like Figures 1-6 As shown in the figure, this embodiment provides an intelligent loading and unloading magnetic core grinding machine tool embodiment.
[0018] A smart magnetic core grinding machine tool with loading and unloading includes a grinding machine body 1 and a conveying device 2. Several magnetic core bodies 3 are placed on the conveying device 2. The conveying device 2 is equipped with a loading and unloading structure 4, which includes a connecting plate 5 fixedly installed on one side of the conveying device 2. A first electric telescopic rod 6 is fixedly installed on the inner side of the connecting plate 5. A connecting block 7 is fixedly installed at the output end of the first electric telescopic rod 6. A second electric telescopic rod 8 is fixedly installed at the bottom of the connecting block 7. An elastic sleeve is installed at the output end of the second electric telescopic rod 8. 9. A limiting ring 10 connected to the magnetic core body 3 is fixedly installed on the main body 1 of the grinding machine tool. Several fixing plates 11 are fixedly installed on both sides of the limiting ring 10. A lead screw 12 is movably installed on the fixing plate 11. Several arc-shaped clamping plates 13 connected to the magnetic core body 3 are provided on the lead screw 12. A first gear 14 is fixedly installed at one end of the lead screw 12. Several drive motors 15 are fixedly installed at one end of the main body 1 of the grinding machine tool. A second gear 16 meshing with the first gear 14 is fixedly installed at the output end of the drive motor 15. By setting up the loading and unloading structure 4, the traditional method of requiring operators to be on duty at the main body 1 of the grinding machine tool and manually placing the magnetic core bodies 3 to be ground one by one onto the fixture of the main body 1 of the grinding machine tool, and then manually removing and sorting qualified and defective products after grinding is changed. When the equipment starts to perform the loading operation, the loading and unloading structure 4 starts to work. The connecting plate 5 fixed on one side of the conveying device 2 provides the installation foundation for the entire loading and unloading structure 4. The first electric telescopic rod 6 inside the connecting plate 5 is activated, and its output end drives the connecting block 7 to extend or adjust its position, thereby causing the second electric telescopic rod 8 fixed at the bottom of the connecting block 7 to move accordingly. After the second electric telescopic rod 8 is activated, its output end drives the elastic sleeve 9 to move. The elastic sleeve 9 grabs or transfers the magnetic core bodies 3 on the conveying device 2, transferring the magnetic core bodies 3 from the conveying device 2 to the limiting ring 10 on the main body 1 of the grinding machine tool. Then, several drive motors 15 at one end of the grinding machine tool body 1 are started. The output end of the drive motor 15 drives the second gear 16 fixedly connected to it to rotate. The second gear 16 meshes with the first gear 14 fixed at one end of the lead screw 12. The rotation of the second gear 16 will drive the first gear 14 and the lead screw 12 to move on the fixed plate 11. During the movement of the lead screw 12, several arc-shaped clamping plates 13 set on it move accordingly, gradually approaching and connecting with the magnetic core body 3 at the limiting ring 10, clamping and fixing the magnetic core body 3. This ensures that the magnetic core body 3 will not be displaced during the grinding process, and also prevents the elastic sleeve 9 from pulling the magnetic core body 3 out when it is detached from the magnetic core body 3. After the magnetic core body 3 is ground, the drive motor 15 rotates in the reverse direction, driving the lead screw 12 to move in the reverse direction through the second gear 16 and the first gear 14, so that the arc-shaped clamping plates 13 are separated from the magnetic core body 3, releasing the fixation of the magnetic core body 3 for subsequent unloading operations. The advantage of this structure is that the entire fixing and loosening process is automatically controlled, the operation is highly consistent, and the difference in fixing effect caused by the difference in the operating habits of different operators is avoided, ensuring the uniformity of the processing accuracy of magnetic cores in the same batch.
[0019] like Figures 1-6 As shown, a protective shell 17 is fixedly installed on the outside of the drive motor 15. Several heat dissipation holes 18 are provided on the protective shell 17. A maintenance cover 19 is provided at one end of the protective shell 17. A first magnetic ring 20 is fixedly installed at the bottom of the maintenance cover 19. A second magnetic ring 21 that is magnetically connected to the first magnetic ring 20 is fixedly installed at the top of the protective shell 17. With the protective shell 17, heat dissipation holes 18, and inspection cover 19, the drive motor 15 at one end of the grinding machine body 1 continuously operates during equipment operation. The protective shell 17 fixed to the outside of the drive motor 15 protects the drive motor 15, preventing external dust, impurities, etc. from entering the drive motor 15 and affecting its normal operation. The drive motor 15 generates heat when it is working. The several heat dissipation holes 18 on the protective shell 17 allow air circulation, dissipating the heat generated by the drive motor 15 in a timely manner and reducing the operating temperature of the drive motor 15. When it is necessary to inspect, maintain, or replace the drive motor 15, the inspection cover 19 at one end of the protective shell 17 can be opened to facilitate the operator to inspect and operate the drive motor 15. After the operation is completed, the inspection cover 19 is closed to restore the protective shell 17 to the protective state of the drive motor 15.
[0020] With the first magnetic ring 20 and the second magnetic ring 21, the maintenance cover 19 at one end of the protective shell 17 is closed during normal operation of the equipment. The first magnetic ring 20 fixed at the bottom of the maintenance cover 19 and the second magnetic ring 21 fixed at the top of the protective shell 17 are magnetically connected to each other. The maintenance cover 19 is tightly fixed to the protective shell 17 by magnetic force, ensuring the protective effect of the protective shell 17 on the drive motor 15. When it is necessary to open the maintenance cover 19, the operator applies a certain external force to overcome the magnetic force between the first magnetic ring 20 and the second magnetic ring 21, so that the first magnetic ring 20 and the second magnetic ring 21 are separated, and the maintenance cover 19 can be opened to carry out maintenance and other operations on the drive motor 15. After the maintenance is completed, the maintenance cover 19 is closed, so that the first magnetic ring 20 and the second magnetic ring 21 are aligned again. Under the action of magnetic force, the first magnetic ring 20 and the second magnetic ring 21 are automatically magnetically connected, realizing the quick fixation of the maintenance cover 19 without the need for additional fixing bolts or other operations.
[0021] like Figures 1-6 As shown, a fixing block 22 is fixedly installed on the second electric telescopic rod 8, and a fixing sleeve 23 connected to the fixing block 22 is fixedly installed on the top of the elastic sleeve 9. Both the fixing block 22 and the fixing sleeve 23 are provided with connecting holes 24. An insert rod 25 is movably installed inside the connecting hole 24, and a latch 26 is fixedly installed at one end of the insert rod 25. With the arrangement of fixing block 22, fixing sleeve 23, connecting hole 24, insert rod 25, and bolt 26, during the assembly or maintenance of the loading / unloading structure 4, when it is necessary to connect and install the elastic sleeve 9 with the second electric telescopic rod 8, align the fixing sleeve 23 fixed at the top of the elastic sleeve 9 with the fixing block 22 fixed on the second electric telescopic rod 8, so that the connecting hole 24 on the fixing block 22 and the fixing sleeve 23 are on the same axis. Insert the insert rod 25 from one end of the connecting hole 24, so that the insert rod 25 passes through the connecting hole 24 on the fixing block 22 and the fixing sleeve 23. 4. Then, rotate the insert rod 25 to adjust the angle of the latch 26 to be perpendicular to the connection hole 24, so that the fixing block 22 can be fixed inside the fixing sleeve 23 to prevent it from falling off, thereby achieving a stable connection between the elastic sleeve 9 and the second electric telescopic rod 8. When it is necessary to disassemble the elastic sleeve 9 for maintenance or replacement, rotate the insert rod 25 to adjust the angle of the latch 26 to be consistent with the connection hole 24, so that the insert rod 25 can be pulled out from the connection hole 24, thereby separating the fixing sleeve 23 from the fixing block 22 and realizing the disassembly of the elastic sleeve 9 and the second electric telescopic rod 8.
[0022] like Figures 1-6 As shown, a number of limiting plates 27 are fixedly installed on the top of the elastic sleeve 9. Push blocks 28 are arranged between the limiting plates 27. A limiting rod 29 is fixedly installed on one end of the push block 28. A limiting hole 30 adapted to the limiting rod 29 is opened on the bolt 26. Insertion holes 31 are opened on both the push block 28 and the limiting plate 27. A fixing rod 32 connected to the push block 28 is installed on the limiting plate 27. With the setting of the limiting plate 27, push block 28, limiting rod 29, and limiting hole 30, when the insertion rod 25 is inserted into the connecting hole 24, the push block 28 is pushed to drive the limiting rod 29 to start moving. When the limiting rod 29 moves to the position of the latch 26 and is inserted into the limiting hole 30, the insertion rod 25 can be limited and fixed, thereby improving the stability of the insertion rod 25 inside the connecting hole 24. Pulling the push block 28 causes the limiting rod 29 to disengage from the limiting hole 30. At this point, the insertion rod 25 can be rotated normally. By inserting the fixing rod 32 into the insertion hole 31 and connecting the limiting plate 27 and the push block 28 together, the push block 28 can be limited and fixed, thereby preventing the push block 28 from sliding between the limiting plates 27 and causing the limiting rod 29 to fail in limiting the insertion rod 25. After the fixing rod 32 is pulled out from the insertion hole 31, the push block 28 can be pushed and pulled normally.
[0023] In this embodiment, as Figures 1-6 As shown in the figure, the working process of the intelligent loading and unloading magnetic core grinding machine provided in this embodiment is as follows: When the equipment starts to perform the loading operation, the loading and unloading structure 4 begins to work. The connecting plate 5, which is fixed to one side of the conveying device 2, provides the installation foundation for the entire loading and unloading structure 4. The first electric telescopic rod 6 inside the connecting plate 5 is activated, and its output end drives the connecting block 7 to extend or adjust its position. This causes the second electric telescopic rod 8, which is fixed at the bottom of the connecting block 7, to move accordingly. After the second electric telescopic rod 8 is activated, its output end drives the elastic sleeve 9 to move. The elastic sleeve 9 grips or transfers the magnetic core body 3 on the conveying device 2, transferring the magnetic core body 3 from the conveying device 2 to the limiting ring 10 on the grinding machine body 1. Then, several drive motors 15 at one end of the grinding machine body 1 are activated. The output end of the drive motor 15 drives the second gear 16, which is fixedly connected to it, to rotate. The first gear 14, which is fixed to one end of the lead screw 12, meshes with the second gear 16. The rotation of the second gear 16 will drive the first gear 14 and the lead screw 12 to move on the fixed plate 11. During the movement of the lead screw 12, several arc-shaped clamps 13 set on it move accordingly, gradually approaching and connecting with the magnetic core body 3 at the limiting ring 10, clamping and fixing the magnetic core body 3. This ensures that the magnetic core body 3 will not be displaced during the grinding process, and also prevents the elastic sleeve 9 from pulling the magnetic core body 3 out when it is detached from the magnetic core body 3. After the magnetic core body 3 is ground, the drive motor 15 rotates in the reverse direction, driving the lead screw 12 to move in the reverse direction through the second gear 16 and the first gear 14, so that the arc-shaped clamps 13 are separated from the magnetic core body 3, releasing the fixation of the magnetic core body 3, so as to facilitate the subsequent unloading operation.

However, as previously stated, it should be understood that the present invention is not limited to the forms disclosed herein and should not be construed as excluding other embodiments.
