Description

Technical Field

[0001] The present invention relates to the technical field of hard disk components, and in particular to a magnetic head polishing device for hard disk production. Background Art

[0002] The hard drive head is a key component for reading data. Its primary function is to convert the magnetic information stored on the hard drive platter into electrical signals for transmission. During the production process, hard drive heads are polished to ensure a smooth surface and improve performance.

[0003] Existing grinding devices usually use a grinding brush with a fixed position to grind one or certain specific positions of the hard disk head. However, hard disk heads are often irregular in shape, and the shapes of hard disk heads of different brands and models are also different. Even the positions of burrs on hard disk heads produced in different batches may deviate. Therefore, the grinding device can only grind certain specific positions and is not fully applicable to hard disk heads. Summary of the Invention

[0004] The technical problem to be solved by the present invention is to provide a magnetic head polishing device for hard disk production in response to the above-mentioned technical deficiencies, which can polish various positions of hard disk heads of various models, has comprehensive and outstanding polishing effects, and has a wide range of applications.

[0005] The technical solution adopted by the present invention is to provide a magnetic head grinding device for hard disk production, comprising a mounting platform; a protective box is provided on the outer surface of the mounting platform; the mounting platform is connected to the protective box via a plurality of shock absorbers; a vibrator is connected to the mounting platform; a plurality of action boxes for placing magnetic heads are fixed on the mounting platform; the action boxes are filled with abrasive powder for grinding the magnetic heads; the upper openings of the action boxes are sealed by sealing members; two clamping members are provided on the left and right sides of the action boxes for clamping the magnetic heads;

[0006] The clamping member includes openings on the front and rear sides of the action box respectively; the two openings correspond to each other; and a compression pad is embedded in the two openings.

[0007] Two pressure pieces are provided on the mounting platform, one on the left and one on the right; the pressure pieces correspond to the clamping pieces on the same side; the pressure pieces are used to apply pressure to the two squeezing pads on the clamping piece so that the two squeezing pads clamp the magnetic head.

[0008] To further optimize the technical solution, a plurality of the action boxes of a magnetic head polishing device for hard disk production are evenly distributed from front to back on the mounting platform; the pressure-applying member includes a base fixed on the mounting platform; a control rod and a guide rod are respectively connected to the base in the front and rear directions; the control rod rotates with the base; the guide rod is fixed to the base; the control rod is provided with an adjustment area corresponding one to one with the clamping member on the same side; the adjustment area is provided with adjustment threads with opposite rotation directions, one in front and one in rear; the adjustment threads are respectively threaded with extension rods; the extension rods are slidably sleeved on the guide rods; the two extension rods are respectively located on the front and rear sides of the corresponding clamping member; a pressure head is fixed on the extension rod; the pressure head corresponds one to one with the extrusion pad.

[0009] To further optimize this technical solution, a control rod of a magnetic head grinding device for hard disk production is driven by a reduction motor connected to a base.

[0010] To further optimize this technical solution, a seal for a magnetic head polishing device for hard disk production includes guide frames fixed on the left and right sides of a mounting platform, and a cover arranged parallel to the mounting platform; the cover is slidably connected to the guide frame along the front-to-back direction; the cover is provided with a storage opening corresponding one-to-one to the upper end of the action box; and the cover is connected with a fixing bolt for positioning.

[0011] To further optimize this technical solution, the upper end of the action box of a magnetic head grinding device for hard disk production is a sloped structure with a low front and a high back; the lower end of the cover is fixed with a wedge block corresponding to the upper end of the action box.

[0012] The beneficial effects of the present invention are:

[0013] After the magnetic head is placed in the action box, the action box is sealed by the seal, and the vibration provided by the vibrator is used to enable the mounting platform to drive the action box to vibrate. The abrasive powder filled inside the action box generates friction with the magnetic head, thereby achieving comprehensive grinding of all parts of the magnetic head.

[0014] On the one hand, the shock absorber connects the installation platform to the protection box. On the other hand, when the vibrator drives the installation platform to vibrate, it reduces the vibration energy transmitted to the protection box and improves the overall stability of the equipment.

[0015] The two clamping parts, one on the left and one on the right, and the matching pressure parts on the action box can be operated by the pressure parts to clamp the magnetic head from different positions respectively. By clamping and positioning the magnetic head, the relative positioning of the magnetic head and the action box can be guaranteed during vibration, so that sufficient relative movement can be generated between the abrasive powder and the magnetic head, thereby increasing the impact friction of the abrasive powder on the magnetic head and improving the grinding effect.

DETAILED DESCRIPTION

[0020] The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0021] like Figure 1-3 As shown, a magnetic head grinding device for hard disk production includes a mounting platform 1; a protective box 2 is provided on the outer surface of the mounting platform 1; the mounting platform 1 is connected to the protective box 2 via multiple shock absorbers 3; a vibrator 4 is connected to the mounting platform 1; multiple action boxes 5 for placing magnetic heads are fixed on the mounting platform 1; the action boxes 5 are filled with abrasive powder for grinding the magnetic heads; the upper openings of the action boxes 5 are sealed by sealing members; two clamping members are provided on the left and right sides of the action boxes 5 for clamping the magnetic heads;

[0022] like Figure 3 As shown, the clamping member includes openings 6 opened on the front and rear sides of the action box 5 respectively; the two openings 6 correspond to each other; and a compression pad 7 is embedded and connected in the two openings 6;

[0023] like Figure 3 As shown, two pressure members are provided on the mounting platform 1 , one on the left and one on the right; the pressure members correspond to the clamping members on the same side; the pressure members are used to apply pressure to the two squeezing pads 7 on the clamping members, so that the two squeezing pads 7 clamp the magnetic head.

[0024] First, put abrasive powder into each action box 5, and then put the magnetic head to be polished into each action box 5. It should be noted that after the magnetic head is placed in the action box 5, the abrasive powder cannot fill the entire space of the action box 5. A certain amount of space must be reserved in the action box 5 to ensure that the clamping part has space to perform the clamping action and to ensure that the abrasive powder has sufficient space to rub and impact the magnetic head.

[0025] Then, by operating a pressure member, the corresponding side clamping member on the action box 5 is activated, and the magnetic head is clamped and positioned by the front and rear squeeze pads 7. The action box 5 is then sealed with a seal. After that, the vibrator 4 is activated, and the mounting platform 1 is vibrated by the vibrator 4 inside the protective box 2. The abrasive powder then impacts and rubs the magnetic head inside the action box 5, achieving a comprehensive polishing effect on the rest of the magnetic head except for the position clamped by the squeeze pad 7. The squeeze pad 7 is made of an elastic material such as rubber or silicone. In addition to being able to elastically deform and recover, it also provides flexible contact with the magnetic head when clamping it to prevent damage to the magnetic head.

[0026] After grinding for a period of time, the clamping part releases the clamping of the magnetic head through the action of the above-mentioned pressure piece, and then another pressure piece is used to control the clamping of the magnetic head at another clamping part, and the vibration operation is performed again. At this time, the clamped position of the magnetic head is changed, and the abrasive powder can grind the previous clamping part of the magnetic head, ensuring the comprehensive grinding effect of the magnetic head, greatly reducing the existing grinding dead angles, and effectively applicable to the comprehensive grinding operation of various types of hard disk heads.

[0027] Abrasive powders may be diamond powder, silicon carbide powder, corundum, white corundum, etc. Depending on the requirements of grinding accuracy, abrasive powders may be selected with appropriate particle sizes, which may be selected by those skilled in the art according to the requirements.

[0028] like Figure 2-3 As shown, multiple action boxes 5 are evenly distributed from front to back on the mounting platform 1; the pressure member includes a base 8 fixed on the mounting platform 1; a control rod 9 and a guide rod 10 are connected to the base 8 along the front and rear directions respectively; the control rod 9 rotates with the base 8; the guide rod 10 is fixed to the base 8; the control rod 9 is provided with an adjustment area corresponding to the clamping member on the same side; the adjustment area is provided with an adjustment thread 11 with opposite rotation directions, one in front and one in back; the adjustment thread 11 is threadedly connected with an extension rod 12; the extension rod 12 is slidably sleeved on the guide rod 10; the two extension rods 12 are respectively located at the front and rear sides of the corresponding clamping member; a pressure head 13 is fixed to the extension rod 12; the pressure head 13 corresponds to the extrusion pad 7 one by one.

[0029] By rotating the control rod 9, the two extension rods 12 on the same adjustment area can be moved closer to or away from each other along the guide rod 10 due to the adjustment threads 11 rotating in opposite directions in the front and rear adjustment areas, so that the pressure head 13 can squeeze or move away from the two corresponding front and rear compression pads 7, thereby achieving convenient control of the clamping and loosening between the clamping part and the magnetic head.

[0030] like Figure 3 As shown, the control rod 9 is driven by the reduction motor 14 connected to the base 8. The reduction motor 14 drives the control rod 9 to move, which can save manpower and improve efficiency. The reduction motor 14 can rotate forward and reverse.

[0031] like Figure 1-2 As shown, the sealing member includes a guide frame 15 fixed on the left and right sides of the mounting platform 1, and a cover 16 arranged parallel to the mounting platform 1; the cover 16 is slidably connected to the guide frame 15 along the front-to-back direction; the cover 16 is provided with a storage opening 17 corresponding to the upper end of the action box 5; the cover 16 is connected with a fixing bolt 18 for positioning.

[0032] By sliding the cover 16 along the guide frame 15, the storage opening 17 can be controlled to connect or isolate the storage opening 17 from the working box 5. When the storage opening 17 is connected to the working box 5, the magnetic head can be easily inserted into each working box 5. When the storage opening 17 is relatively isolated from the working box 5, the cover 16 seals the working box 5, ensuring stable operation during the grinding process. The set screw 18 is used to secure the cover 16 in the desired position at any time.

[0033] like Figure 2 As shown, the upper end of the action box 5 is a sloped structure with a lower front and a higher back; a wedge-shaped block 19 corresponding to the upper end of the action box 5 is fixed to the lower end of the cover 16.

[0034] By pushing the action box 5 backward, the wedge block 19 can be moved closer to the upper end of the action box 5, and the contact between the wedge block 19 and the inclined surface structure at the upper end of the action box 5 can be closer, ensuring the tightness of the seal and effectively preventing the leakage of abrasive powder during vibration action.

[0035] It will be understood that the present invention is described by way of some embodiments, and it will be appreciated by those skilled in the art that various changes or equivalent substitutions may be made to these features and embodiments without departing from the spirit and scope of the present invention. In addition, under the teachings of the present invention, these features and embodiments may be modified to adapt to specific circumstances and materials without departing from the spirit and scope of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed herein, and all embodiments falling within the scope of the claims of this application are intended to be protected by the present invention.
