Description

Technical Field

[0001] This invention relates to the field of magnetic head manufacturing technology, and in particular to a magnetic head shell polishing device. Background Technology

[0002] The magnetic head used in banknote detectors is mostly composed of an outer shell, a magnetic shell, an insulating disk, an insulating post, a copper ring, and a winding. The lower end of the copper ring is fused with pins, and the lower end of the pins is used for welding cables, FPCs, and circuit boards, etc.

[0003] A magnetic head is a component that reads data from a magnetic medium using magnetic principles. Common magnetic heads include hard disk heads and magnetic tape recorder heads. Existing banknote detector magnetic head housings have an opening on one side for securing the head, and a through-hole on the other side of the shielding cover for collecting banknote signals.

[0004] During the production of magnetic heads, the outer shell of the magnetic head needs to be polished. Patent application number 201721782236.0 discloses a polishing device for producing magnetic heads. After the magnetic head is produced, the magnetic head to be polished is placed between an upper fixed block and a lower fixed block and locked by a locking mechanism. Rotating the rotating rod drives the movement of the moving box through the rotation of the threaded rod, thereby realizing the movement of the grinding disc. Then, the magnetic head is polished by the grinding disc. However, this type of polishing device has low efficiency in polishing magnetic heads. It is necessary to fix the magnetic head before polishing, and after polishing, the magnetic head needs to be removed before the next polishing can be performed, resulting in low polishing efficiency.

[0005] This invention was developed to address the shortcomings of existing technologies. Summary of the Invention

[0006] The purpose of this invention is to overcome the shortcomings of the prior art and provide a magnetic head housing polishing device.

[0007] This invention can be achieved through the following technical solutions: This invention discloses a magnetic head shell grinding device, comprising a table, a top plate fixed above the table, a rotary motor fixed on the top plate, a turntable fixed at the output end of the rotary motor, and multiple limiting devices evenly fixed on the turntable. Each limiting device includes a limiting tube fixed on the turntable, a limiting rod slidably connected to the limiting tube on the limiting tube, a fixing block fixed at the bottom of the limiting rod, a limiting block fixed at the top of the limiting rod, a spring between the limiting block and the limiting tube, a limiting shaft fixed on each limiting block, and a roller on each limiting shaft. A support ring cooperating with the roller is also fixed on the top plate, and a grinding disc is also provided on the table, the grinding disc being driven to rotate by a grinding motor. When the outer shell opening faces upwards and reaches the fixed block position, the turntable is driven to rotate by a rotary motor. The rollers rotate with the turntable and move on the surface of the support ring. As the height of the bottom of the support ring gradually decreases from one end to the other, the fixed block descends. The bottom of the fixed block enters the outer shell, causing the outer shell to move. When the outer shell reaches the grinding disc position, the bottom of the outer shell is on the surface of the grinding disc. The grinding disc is driven to rotate by a grinding motor, and the grinding disc polishes the opening of the outer shell smoothly, thus achieving the grinding of the outer shell. This device can achieve the grinding of the outer shell. Furthermore, by inserting the fixed block into the outer shell during movement, the outer shell is fixed and moved, thus moving the outer shell to the grinding disc position for grinding. Moreover, by using multiple fixed blocks to move the outer shell to the grinding disc position with the rotation of the turntable, there is no need to wait for the outer shell to be removed and repositioned, achieving continuous grinding of the outer shell.

[0008] Preferably, the platform is further provided with a feeding device, which includes a feeding tray with multiple feeding slots evenly arranged on it. A baffle is also fixed on the platform outside the feeding tray, and a feeding port is provided on one side of the baffle. The outer shell is placed in the feeding slot of the feeding tray, and the feeding tray is rotated by a feeding motor to move the outer shell to a designated position for the fixing block to grasp.

[0009] Preferably, the table surface is further provided with a feeding port, and a feeding motor is fixed on the table surface at the feeding port position. A rotating shaft is fixed to the output end of the feeding motor, and multiple scrapers are fixed on the rotating shaft. When the polished shell reaches the feeding port position, the feeding motor starts, and the feeding motor drives the scrapers to rotate around the rotating shaft. After the scrapers contact the shell at the fixed block position, they push the shell to move and separate from the fixed block.

[0010] Compared with existing technologies, the present invention has the following advantages: This device can polish the outer shell. By inserting a fixed block into the outer shell during movement, the outer shell is fixed and moved to the polishing disc position for polishing. Furthermore, multiple fixed blocks rotate with the turntable, moving the outer shell to the polishing disc position, eliminating the need to wait for the outer shell to be removed and repositioned, thus enabling continuous polishing of the outer shell.

[0012] The embodiments of the present invention will now be described in detail with reference to the accompanying drawings: Example

[0013] like Figs. 1 to 3As shown, this embodiment discloses a magnetic head shell polishing device, including a table 1, a top plate 7 fixed above the table 1, a rotary motor 8 fixed on the top plate 7, a turntable 9 fixed at the output end of the rotary motor 8, and a plurality of limiting devices 10 evenly fixed on the turntable 9. Each limiting device 10 includes a limiting tube 11 fixed on the turntable 9, a limiting rod 12 slidably connected to the limiting tube 11, a fixing block 13 fixed at the bottom of the limiting rod 12, a limiting block 14 fixed at the top of the limiting rod 12, a spring 18 between the limiting block 14 and the limiting tube 11, a limiting shaft 15 fixed on each limiting block 14, a roller 16 fixed on each limiting shaft 15, a support ring 17 for use with the roller 16 fixed on the top plate 7, and a polishing disc 19 on the table 1, which is driven to rotate by a polishing motor 20. When the outer shell opening faces upward and reaches the position of the fixing block 13, the rotary motor 8 drives the turntable 9 to rotate, and the roller 16 rotates with the turntable 9. The roller 16 moves on the surface of the support ring 17. Since the height of the bottom of the support ring 17 gradually decreases from one end of the support ring 17 to the other end, the fixing block 13 descends. The bottom of the fixing block 13 enters the outer shell and drives the outer shell to move. When the outer shell reaches the position of the grinding disc 19, the bottom of the outer shell is on the surface of the grinding disc 19. The grinding motor 20 drives the grinding disc 19 to rotate, and the grinding disc 19 polishes the opening of the outer shell smoothly, thus realizing the grinding of the outer shell. This device can realize the grinding of the outer shell. When the fixing block 13 moves, it inserts into the outer shell to fix the outer shell and drives the outer shell to move. This realizes the grinding of the outer shell by moving the outer shell to the position of the grinding disc 19. Furthermore, by multiple fixing blocks 13 rotating with the turntable 9, the outer shell is driven to the position of the grinding disc 19, without waiting to remove the outer shell and place it again, thus realizing the continuous grinding of the outer shell.

[0014] The platform 1 is equipped with a feeding device, which includes a feeding tray 2 with multiple feeding slots 4 evenly distributed on it. A baffle 5 is fixed on the platform 1 outside the feeding tray 2, and a feeding port 6 is provided on one side of the baffle 5. The outer shell is placed in the feeding slots 4 of the feeding tray 2, and the feeding tray 2 is rotated by the feeding motor 3 to move the outer shell to a designated position for the fixing block 13 to grasp. Example

[0015] This embodiment discloses a magnetic head shell polishing device. Based on the structure and principle of Embodiment 1, this embodiment further includes a feeding port 21 on the table 1. A feeding motor 22 is fixed on the table 1 at the feeding port 21, and a rotating shaft 23 is fixed to the output end of the feeding motor 22. Multiple scraper blades 24 are also fixed on the rotating shaft 23. When the polished shell reaches the feeding port 21, the feeding motor 22 starts and drives the scraper blades 24 to rotate around the rotating shaft 23. After the scraper blades 24 contact the shell at the fixed block 13, they push the shell to move and separate from the fixed block 13.
