Description

Technical Field

[0002] In the field of modern data storage and information reading, the magnetic head is a crucial core component, and its performance directly affects the accuracy and stability of data reading and writing. The magnetic head housing, as an important structure for protecting the magnetic head, its processing quality has a crucial impact on the service life and working performance of the magnetic head. The grinding process, as a key link in the production of magnetic head housings, aims to remove burrs and defects on the surface of the housing, and ensure the dimensional accuracy and surface finish of the housing to meet the assembly requirements of internal components of the magnetic head and the working environment requirements.

[0003] Currently, the shapes of magnetic head housings are rich and diverse, covering various structures such as cuboid, arc-top rectangle, and one-end open cylinder. However, in the existing grinding operations of magnetic head housings, most still rely on manual operation. Due to the small size of the magnetic head housing, it is difficult to reach the internal fine parts during manual grinding, resulting in the problem that the grinding work cannot cover all areas of the housing, and the problem of incomplete grinding is very prominent. This not only reduces the surface quality of the product, but also makes it easy to have poor fitting during the subsequent assembly of the magnetic head housing, significantly increasing the defective rate of product processing. In addition, manual operation can only process a single magnetic head housing each time, and the production efficiency is extremely low, making it difficult to meet the growing market demand and unable to adapt to the modern large-scale and high-efficiency production mode.

Detailed implementation manner

[0018] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0019] In the existing polishing operation of the magnetic head housing, most still rely on manual operation. When manually polishing, it is difficult to reach the internal fine parts. In addition, each manual operation can only process a single magnetic head housing, and the production efficiency is extremely low.

[0020] Therefore, the present invention provides an automatic polishing device for the production of magnetic head housings. Refer to Figures 1 - 10 As shown, it includes a mounting frame 1 and a loading robotic arm 43. A mounting shell 2 is slidably connected between the inner walls on both sides of the mounting frame 1.

[0021] The loading robotic arm 43 in this technical solution is a relatively mature technology in the prior art. Its installation method, usage method, and programming method are all common knowledge among those skilled in the art, so they will not be elaborated in this technical solution.

[0022] Specifically, refer to Figures 2 - 9 As shown, the outer wall grinding assembly includes a circular plate 5. The bottom of the inner cavity of the installation shell 2 is movably connected to the circular plate 5 through a rotating shaft and a bearing. The top of the circular plate 5 is provided with evenly distributed installation circular holes 6. The inner wall of the installation circular hole 6 is rotatably connected to a placement tube 7. Both ends of the placement tube 7 extend to the outside of the installation circular hole 6 respectively. A vertical tube 10 is arranged in the placement tube 7. The outer wall of the vertical tube 10 is slidably connected to the inner wall of the placement tube 7. A number of evenly distributed first grinding brushes 11 are fixedly connected to the inner wall of the vertical tube 10. The top end of the vertical tube 10 extends above the placement tube 7. A movable gear ring 8 is fixedly connected to the outer wall of the placement tube 7 near the top. A fixed gear ring 9 is fixedly connected to the inner wall of the installation shell 2 near the top. The movable gear ring 8 meshes with the fixed gear ring 9. A first motor 12 is installed at the bottom of the installation shell 2. The bottom end of the rotating shaft on the circular plate 5 passes through the inner ring of the bearing and extends below the installation shell 2 and is fixedly connected to the output end of the first motor 12.

[0023] Specifically, refer to Figures 2 - 10 As shown, the inner wall grinding assembly includes a fixed plate 13 and a transmission mechanism. The outer wall of the installation shell 2 is fixedly connected to the fixed plate 13. The fixed plate 13 is arranged in an L shape. A square rod 14 is arranged above the fixed plate 13. The bottom end of the square rod 14 penetrates through the fixed plate 13 and is movably connected to the fixed plate 13. The bottom end of the square rod 14 is rotatably connected to a lifting plate 15. The bottom of the lifting plate 15 is movably connected through a bearing to a number of evenly distributed rotating tubes 16. A rotating rod 19 is arranged in the rotating tube 16. The bottom end of the rotating rod 19 extends below the rotating tube 16. Evenly distributed second grinding brushes 20 are fixedly connected to the side wall of the rotating tube 16 near the bottom. The second grinding brushes 20 correspond to the top of the placement tube 7. The bottom end of the rotating rod 19 is fixedly connected to a grinding plate 22. Synchronous rods 46 are symmetrically fixedly connected to the top of the circular plate 5. The top ends of the two synchronous rods 46 respectively penetrate through the lifting plate 15 and extend above the lifting plate 15. The transmission mechanism includes a grooved wheel 17. Grooved wheels 17 are fixedly connected to the side walls of a number of rotating tubes 16 near the top. A synchronous belt 18 is installed between a number of grooved wheels 17. The top end of one of the rotating tubes 16 passes through the inner ring of the bearing and extends above the lifting plate 15. A second motor 21 is installed at the top end of the lifting plate 15. The top end of the rotating tube 16 is fixedly connected to the output end of the second motor 21.

[0024] During operation, first, the servo motor 40 is started by an external power supply to drive the screw rod 39 to rotate forward, causing the positioning plate 37 to drive the entire mounting shell 2 to move in the direction of the loading manipulator 43. When the mounting shell 2 moves in the direction of the loading manipulator 43, the pulley 27 will roll on the bottom of the inner cavity of the L-shaped plate 41. When the pulley 27 rolls to a position close to the loading manipulator 43, it will roll along the inclined surface of the L-shaped plate 41. Synchronously, the spring 26 pushes the limiting plate 25 and the square rod 14 to rise, causing the second grinding brush 20 on the rotating rod 19 to disengage from the vertical pipe 10 and rise. When the mounting shell 2 is displaced to the limit position in the direction of the loading manipulator 43, the rotation of the screw rod 39 stops. Next, the loading manipulator 43 clamps the pre-palletized magnetic head housings and places them into the vertical pipe 10 in sequence, and the closed ends of the magnetic head housings need to be placed downward. In this way, the bottom end of the magnetic head housing will pass through the vertical pipe 10 and contact the grinding disc 30. After the placement is completed, the servo motor 40 is started to drive the screw rod 39 to rotate in reverse, causing the positioning plate 37 and the mounting shell 2 to move in the direction of the servo motor 40 as a whole. Synchronously, the pulley 27 moves along the inclined surface at the top of the inner cavity of the L-shaped plate 41, causing the pulley 27 and the limiting plate 25 to descend and compress the spring 26. Synchronously, the lifting plate 15 and the rotating pipe 16 follow and descend, causing the second grinding brush 20 and the grinding plate 22 to enter the magnetic head housing. After the second grinding brush 20 completely enters the magnetic head housing, the servo motor 40 is turned off. Next, the first motor 12 is started by an external power supply, and the first motor 12 drives the circular plate 5 to rotate as a whole. When the circular plate 5 rotates, because the placement pipe 7 meshes with the fixed gear ring 9, when the circular plate 5 rotates, multiple placement pipes 7 will rotate forward simultaneously. When the circular plate 5 rotates, it will drive multiple magnetic head housings to rotate simultaneously. The outer wall bottom of the magnetic head housing is ground by the grinding disc 30, and at the same time, the rotation of the vertical pipe 10 grinds the side wall of the magnetic head housing.

[0025] To grind the inner wall of the magnetic head housing simultaneously, the second motor 21 is started by an external control power supply. The second motor 21 drives one of the rotating pipes 16 and the sprocket 17 to rotate in reverse. Synchronously, the sprocket 17 drives multiple rotating pipes 16 to rotate in reverse synchronously through the synchronous belt 18. The rotating pipe 16 drives the rotating rod 19, the second grinding brush 20, and the grinding plate 22 to rotate in reverse, enabling the second grinding brush 20 to grind the inner wall of the magnetic head housing. In addition, importantly, through the forward rotation of the placement pipe 7 and the reverse rotation of the rotating rod 19, opposite frictional forces are generated between the second grinding brush 20 and the first grinding brush 11 against the magnetic head housing. In this way, the magnetic head housing will not rotate or will rotate slowly in the vertical pipe 10, which will not affect the grinding of the magnetic head housing. In addition, when the circular plate 5 rotates, the lifting plate 15 above is driven to rotate as a whole through the synchronous rod 46. In this way, the circular plate 5 and the lifting plate 15 can rotate synchronously and in the same direction, avoiding the occurrence of jamming.

[0026] Specifically, refer to Figures 5 - 6As shown, the automatic discharging assembly includes a discharging opening 28. Discharging openings 28 are symmetrically formed at the bottom of the mounting shell 2. A bottom plate 29 is slidably connected between the inner walls on both sides of the two discharging openings 28. A T-shaped sliding groove 31 is formed at the bottom of the mounting shell 2. A T-shaped sliding bar 32 is installed in the T-shaped sliding groove 31. The bottom of the T-shaped sliding bar 32 passes through the T-shaped sliding groove 31 and extends below the mounting shell 2 and is fixedly connected to a connecting plate 34. One end of the T-shaped sliding bar 32 extends outside the T-shaped sliding groove 31 and is fixedly connected to a top plate 33. The bottom of the connecting plate 34 is symmetrically and movably connected to a pull rod 35. Both ends of the two pull rods 35 are respectively movably connected to the bottom of the bottom plate 29. A tension spring 36 is fixedly connected between the two pull rods 35.

[0027] During operation, when the servo motor 40 is restarted after the grinding is completed, the screw rod 39 is driven to reverse by the servo motor 40, so that the entire mounting frame 1 continues to move in the direction of the servo motor 40, making the top plate 33 contact the support leg 45. And as the mounting shell 2 continues to move, through the reaction force of the support leg 45, the T-shaped sliding bar 32 simultaneously pushes the two bottom plates 29 to slide outwards through the pull rod 35 to stretch the tension spring 36, achieving the effect of opening the discharging opening 28. When the position of the mounting shell 2 is displaced to the limit position in the direction of the servo motor 40, the servo motor 40 is turned off. Synchronously, the rotation speed of the first motor 12 decreases. During the rotation of the circular plate 5, multiple magnetic head housings will fall downward through the discharging opening 28 into the material receiving bottom box 44, achieving the purpose of discharging. When all the discharging is completed, the feeding can be carried out again.

[0028] Specifically, refer to Figures 1 - 2 As shown, the lifting assembly includes a limiting plate 25. A limiting plate 25 is fixedly connected to the side wall of the square rod 14 near the top. A spring 26 is sleeved on the side wall of the square rod 14. One end of the spring 26 is fixedly connected to the limiting plate 25, and the other end is fixedly connected to the top of the lifting plate 15. A pulley 27 is installed at the top of the square rod 14. An L-shaped plate 41 is fixedly connected to the top of the mounting frame 1. The top of the L-shaped plate 41 is arranged in a Z shape. The side wall of the pulley 27 contacts the top of the inner cavity of the L-shaped plate 41. A reinforcing plate 42 is sleeved on the side wall of the L-shaped plate 41. The bottom end of the reinforcing plate 42 is fixedly connected to the top of the mounting frame 1. The top of the L-shaped plate 41 is fixedly connected to the bottom of the inner cavity of the reinforcing plate 42.

[0029] During operation, when the pulley 27 rolls to a position close to the feeding robotic arm 43, it will roll along the inclined surface of the L-shaped plate 41. Synchronously, the spring 26 pushes the limiting plate 25 and the square rod 14 to rise, so that the second grinding brush 20 on the rotating rod 19 disengages from the vertical pipe 10 and rises. On the contrary, when the mounting shell 2 moves in the other direction, the pulley 27 moves along the inclined surface of the top of the inner cavity of the L-shaped plate 41, causing the pulley 27 and the limiting plate 25 to descend to compress the spring 26. Synchronously, the lifting plate 15 and the rotating pipe 16 follow and descend, so that the second grinding brush 20 and the grinding plate 22 enter the magnetic head housing.

[0030] Specifically, refer to Figures 1 - 10 As shown, the displacement component includes a positioning plate 37. The bottom of the installation shell 2 is fixedly connected to the positioning plate 37. A screw hole 38 is opened on one side of the positioning plate 37. A screw rod 39 is installed in the screw hole 38. The bottom of the installation frame 1 is symmetrically and fixedly connected with support legs 45. Both ends of the screw rod 39 are movably connected to the support legs 45 through bearings. A servo motor 40 is installed on one side of the support leg 45. One end of the screw rod 39 passes through the inner ring of the bearing and extends to the outside of the support leg 45 and is fixedly connected to the output end of the servo motor 40. A material receiving bottom box 44 is fixedly connected between the two support legs 45.

[0031] During operation, the servo motor 40 is started through an external power supply to drive the screw rod 39 to rotate forward or backward, so that the positioning plate 37 drives the entire installation shell 2 to move in the direction of the feeding robotic arm 43 or the direction of the servo motor 40, and the functions of feeding and automatic discharging can be realized.

[0032] Among them, support sliders 3 are symmetrically and fixedly connected to the outer wall of the installation shell 2. Support slide rails 4 are opened on the inner walls of the two sides of the installation frame 1 opposite to the support sliders 3. One side of the support slider 3 extends into the support slide rail 4. Through the support slide rail 4 and the support slider 3, the installation shell 2 can slide stably without falling. When necessary, lubricating grease can be applied in the slide rail, which is beneficial to reducing friction and improving the service life.

[0033] In addition, grinding sheets 30 are respectively fixedly connected to the bottom of the inner cavity of the installation shell 2 and the top of the bottom plate 29. The grinding sheets 30 are arranged in a ring shape. Through the grinding sheets 30, the bottom of the magnetic head housing can be ground. When the circular plate 5 rotates, it will drive the magnetic head housing to slide on the grinding sheets 30, so as to achieve the purpose of grinding.

[0034] Among them, a threaded hole 23 is opened on the side wall of the rotating tube 16. A bolt 24 is installed in the threaded hole 23. One end of the bolt 24 extends into the rotating tube 16 and contacts the rotating rod 19. The rotating rod 19 can be fixed through the threaded hole 23 and the bolt 24, so that the rotating rod 19 can be disassembled and installed, which is convenient for later maintenance and replacement of the second grinding brush 20.

[0035] To sum up, it effectively solves the problem that in the existing grinding operation of the magnetic head housing, most still rely on manual operation. It is difficult to reach the internal fine parts during manual grinding. In addition, only a single magnetic head housing can be processed each time during manual operation, and the production efficiency is extremely low.

[0036] Working principle: When the present invention is in use, first place the entire mounting frame 1 at the target position and complete installation and debugging. It is necessary to program the running trajectory and fixture logic of the loading robotic arm 43. After programming, the loading robotic arm 43 can cooperate with the mounting shell 2. After installation and debugging, if the magnetic head housing needs to be polished, first start the servo motor 40 through an external power supply to drive the screw rod 39 to rotate forward, so that the positioning plate 37 drives the entire mounting shell 2 to move towards the loading robotic arm 43. When the mounting shell 2 moves towards the loading robotic arm 43, the pulley 27 will roll at the bottom of the inner cavity of the L-shaped plate 41. When the pulley 27 rolls to a position close to the loading robotic arm 43, it will roll along the inclined surface of the L-shaped plate 41. Synchronously, the spring 26 pushes the limiting plate 25 and the square rod 14 to rise, so that the second grinding brush 20 on the rotating rod 19 disengages from the vertical pipe 10 and rises. When the mounting shell 2 is displaced to the limit position towards the loading robotic arm 43, stop rotating the screw rod 39. Next, the loading robotic arm 43 clamps the pre-piled magnetic head housings in sequence and places them into the vertical pipe 10, and the closed end of the magnetic head housing needs to be placed downward. In this way, the bottom end of the magnetic head housing will pass through the vertical pipe 10 and contact the grinding sheet 30. After the placement is completed, start the servo motor 40 to drive the screw rod 39 to rotate in reverse, so that the positioning plate 37 and the entire mounting shell 2 move towards the servo motor 40. Synchronously, the pulley 27 moves along the inclined surface at the top of the inner cavity of the L-shaped plate 41, so that the pulley 27 and the limiting plate 25 descend to compress the spring 26. Synchronously, the lifting plate 15 and the rotating pipe 16 follow and descend, so that the second grinding brush 20 and the grinding plate 22 enter the magnetic head housing. After the second grinding brush 20 completely enters the magnetic head housing, turn off the servo motor 40. Next, start the first motor 12 through an external power supply. The first motor 12 drives the circular plate 5 to rotate as a whole. When the circular plate 5 rotates, because the placement pipe 7 meshes with the fixed toothed ring 9, when the circular plate 5 rotates, multiple placement pipes 7 will rotate forward simultaneously. When the circular plate 5 rotates, it will drive multiple magnetic head housings to rotate simultaneously. The outer wall bottom of the magnetic head housing is polished by the grinding sheet 30, and the rotation of the vertical pipe 10 polishes the side wall of the magnetic head housing.

[0037] In order to polish the inner wall of the head housing simultaneously, the second motor 21 is started by connecting to an external control power supply. The second motor 21 drives one of the rotating tubes 16 and the sheave 17 to reverse. Synchronously, the sheave 17 drives multiple rotating tubes 16 to reverse synchronously through the synchronous belt 18. The rotating tubes 16 drive the rotating rods 19, the second polishing brushes 20 and the polishing plates 22 to reverse, so that the second polishing brushes 20 can polish the inner wall of the head housing. Additionally, importantly, through the forward rotation of the placing tube 7 and the reverse rotation of the rotating rods 19, opposite frictional forces are generated between the second polishing brushes 20 and the first polishing brushes 11 on the head housing, so that the head housing does not rotate or rotates slowly within the vertical tube 10, which will not affect the polishing of the head housing. Additionally, when the circular plate 5 rotates, the lifting plate 15 above is driven to rotate integrally through the synchronous rod 46, so that the circular plate 5 and the lifting plate 15 can rotate synchronously and in the same direction, avoiding jamming.

[0038] When the polishing is completed, the servo motor 40 is started again. The servo motor 40 drives the screw 39 to reverse, so that the mounting frame 1 as a whole continues to move towards the servo motor 40, causing the top plate 33 to contact the support leg 45. And as the mounting shell 2 continues to move, due to the reaction force of the support leg 45, the T-shaped slide 32 simultaneously pushes the two bottom plates 29 to slide outwards through the pull rod 35 to stretch the tension spring 36, achieving the effect of opening the discharge opening 28. When the position of the mounting shell 2 moves towards the servo motor 40 to the limit position, the servo motor 40 is turned off. Synchronously, the rotation speed of the first motor 12 decreases. During the rotation of the circular plate 5, multiple head housings will fall downward through the discharge opening 28 into the receiving bottom box 44, achieving the purpose of discharging. When all the discharging is completed, feeding can be carried out again. By repeating the above operations, feeding can be completed. When the mounting shell 2 moves towards the feeding robotic arm 43, the tension spring 36 will also contract, pulling the two pull rods 35 to drive the bottom plates 29 to move towards the center of the mounting shell 2, achieving the effect of closing the discharge opening 28. At this time, the T-shaped slide 32 will also slide towards the tension spring 36 and return to the initial position.

[0039] This process can be repeated to polish more magnetic head housings. Since the first polishing brush 11 and the second polishing brush 20 will inevitably wear out after long-term use, which will reduce the polishing accuracy and efficiency. Therefore, if the first polishing brush 11 and the second polishing brush 20 are worn out, they can be disassembled and replaced. First, when replacing the first polishing brush 11 and the second polishing brush 20, the entire mounting shell 2 needs to be positioned close to the loading robotic arm 43 so that the second polishing brush 20 rises to its extreme position. Next, loosen the bolt 24, and then the rotating rod 19 and the second polishing brush 20 can be removed. Insert the new rotating rod 19 and the second polishing brush 20 into the rotating tube 16 and tighten the bolt 24 to fix the rotating rod 19 on the rotating tube 16. When replacing the first polishing brush 11, simply pull out the vertical tube 10 from the placement tube 7. Since the vertical tube 10 is slidably connected to the placement tube 7, there are chutes and sliders between the placement tube 7 and the vertical tube 10 to limit the rotation of the vertical tube 10 following the placement tube 7 and to indicate the position of the vertical tube 10 so that the vertical tube 10 does not fall. Then, place the new vertical tube 10 and the first polishing brush 11 in the placement tube 7 to complete the replacement, making the maintenance more convenient.
