Description

Technical Field

[0001] The present invention relates to the technical field of automated mechanical processing, in particular to an automated polishing device for producing magnetic head shells. Background Art

[0002] In the field of modern data storage and information reading, the performance of the magnetic head, as a key core component, directly affects the accuracy and stability of data reading and writing. The magnetic head housing, as an important structure to protect the magnetic head, has a crucial impact on the service life and working performance of the magnetic head. The polishing process is a key link in the production process of the magnetic head housing. It 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 the internal components of the magnetic head and the working environment requirements.

[0003] At present, the shapes of magnetic head shells are rich and varied, covering a variety of structures such as rectangular, arc-top rectangles, and cylinders with one end open. However, in the existing magnetic head shell polishing operations, most of them still rely on manual operation. Due to the small size of the magnetic head shell, it is difficult to reach the fine internal parts during manual polishing, resulting in the polishing work being unable to cover the entire area of ​​the shell. The problem of incomplete polishing is very prominent, which not only reduces the surface quality of the product, but also makes the magnetic head shell prone to poor matching during the subsequent assembly process, greatly increasing the product processing defect rate. In addition, manual operation can only process a single magnetic head shell at a time, and the production efficiency is extremely low, which is difficult to meet the growing market demand and cannot adapt to the modern large-scale and high-efficiency production model.

[0039] The loading robot arm 43 in this technical solution is a relatively mature technology in the existing field. Its installation method, usage method and programming method are all common knowledge among people in this field, so they are not described in detail in this technical solution.

[0040] For details, see Figure 2-Figure 9 As shown, the outer wall grinding assembly includes a circular plate 5, and the bottom of the inner cavity of the mounting 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 mounting circular holes 6, and the inner wall of the mounting circular hole 6 is rotatably connected to a placement tube 7. Both ends of the placement tube 7 extend to the outside of the mounting circular hole 6 respectively. A vertical tube 10 is provided 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. The inner wall of the vertical tube 10 is fixedly connected to a number of evenly distributed first grinding brushes 11. The top of the vertical tube 10 extends to the top of the placement tube 7. The outer wall of the placement tube 7 is fixedly connected to a movable gear ring 8 near the top, and the inner wall of the mounting shell 2 is fixedly connected to a fixed gear ring 9 near the top. The movable gear ring 8 is meshed with the fixed gear ring 9. A first motor 12 is installed at the bottom of the mounting shell 2. The bottom end of the rotating shaft on the circular plate 5 passes through the inner ring of the bearing and extends to the bottom of the mounting shell 2 and is fixedly connected to the output end of the first motor 12.

[0041] For details, see Figure 2-Figure 10As shown, the inner wall grinding assembly includes a fixed plate 13 and a transmission mechanism. The outer wall of the mounting shell 2 is fixedly connected to the fixed plate 13. The fixed plate 13 is L-shaped. A square rod 14 is provided above the fixed plate 13. The bottom end of the square rod 14 passes 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 to a number of evenly distributed rotating tubes 16 through bearings. A rotating rod 19 is provided in the rotating tube 16. The bottom end of the rotating rod 19 extends to the bottom of the rotating tube 16. A second grinding brush 20 is evenly distributed and fixedly connected to the side wall of the rotating tube 16 near the bottom. The second grinding brush The brush 20 corresponds to the top of the placement tube 7, the bottom end of the rotating rod 19 is fixedly connected to the grinding plate 22, and the top of the circular plate 5 is symmetrically fixedly connected to the synchronization rod 46. The top ends of the two synchronization rods 46 respectively pass through the lifting plate 15 and extend to the top of the lifting plate 15. The transmission mechanism includes a groove wheel 17, and several rotating tubes 16 are fixedly connected to the groove wheel 17 near the top on the side wall. A synchronous belt 18 is installed between the groove wheels 17. The top end of one of the rotating tubes 16 passes through the inner ring of the bearing and extends to the top of the lifting plate 15. A second motor 21 is installed on the top of the lifting plate 15, and the top end of the rotating tube 16 is fixedly connected to the output end of the second motor 21.

[0042] When working, first start the servo motor 40 through the external power supply to drive the screw 39 to rotate forward, so that the positioning plate 37 drives the installation shell 2 to move as a whole towards the upper feeding robot arm 43. When the installation shell 2 moves in the direction of the upper feeding robot 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 feeding robot arm 43, it will roll along the inclined surface of the L-shaped plate 41. The synchronous spring 26 pushes the limit plate 25 and the square rod 14 to rise, so that the second grinding brush 20 on the rotating rod 19 is separated from the vertical tube 10 and rises. When the installation shell 2 is displaced to the limit position towards the upper feeding robot arm 43, the rotation of the screw 39 is stopped. Next, the feeding robot arm 43 will clamp the pre-stacked magnetic head shells and place them in the vertical tube 10 in turn, and the closed end of the magnetic head shell needs to be placed downwards, so that the bottom end of the magnetic head shell will pass through the vertical tube 10 and contact the grinding disc 30. , start the servo motor 40 to drive the screw 39 to reverse, so that the positioning plate 37 and the mounting shell 2 move as a whole toward the direction of the servo motor 40, and the synchronous pulley 27 moves along the inclined surface of the top of the inner cavity of the L-shaped plate 41, so that the pulley 27 and the limit plate 25 descend to compress the spring 26, and the synchronous lifting plate 15 and the rotating tube 16 follow and descend, so that the second grinding brush 20 and the grinding plate 22 enter the magnetic head shell. When the second grinding brush 20 completely enters the magnetic head shell, 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 tube 7 is engaged with the fixed gear ring 9, the rotation of the circular plate 5 will cause multiple placement tubes 7 to rotate forward at the same time. When the circular plate 5 rotates, it will drive multiple head shells to rotate at the same time, and the grinding sheet 30 grinds the bottom of the outer wall of the magnetic head shell, and at the same time, the rotation of the vertical tube 10 grinds the side wall of the magnetic head shell.

[0043] In order to grind the inner wall of the magnetic head shell at the same time, the second motor 21 is started by an external control power supply, and the second motor 21 drives one of the rotating tubes 16 and the groove wheel 17 to reverse, and the groove wheel 17 drives multiple rotating tubes 16 to reverse synchronously through the synchronous belt 18. The rotating tube 16 drives the rotating rod 19, the second grinding brush 20 and the grinding plate 22 to reverse, so that the second grinding brush 20 can grind the inner wall of the magnetic head shell. In addition, it is important that the second grinding brush 20 and the first grinding brush 11 generate opposite friction forces on the magnetic head shell through the forward rotation of the placement tube 7 and the reverse rotation of the rotating rod 19, so that the magnetic head shell will not rotate in the vertical tube 10, or will rotate slowly, which will not affect the grinding of the magnetic head shell. In addition, when the circular plate 5 rotates, the upper lifting plate 15 is driven to rotate as a whole through the synchronous rod 46, so that the circular plate 5 and the lifting plate 15 can rotate synchronously and in the same direction to avoid jamming.

[0044] For details, see Figure 5-Figure 6As shown, the automatic discharging assembly includes a discharging opening 28, and the discharging opening 28 is symmetrically opened 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, and a T-shaped slide 31 is opened at the bottom of the mounting shell 2. A T-shaped slide 32 is installed in the T-shaped slide 31. The bottom of the T-shaped slide 32 passes through the T-shaped slide 31 and extends to the bottom of the mounting shell 2 and is fixedly connected to a connecting plate 34. One end of the T-shaped slide 32 extends to the outside of the T-shaped slide 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. The two ends of the two pull rods 35 are movably connected to the bottom of the bottom plate 29 respectively, and a tension spring 36 is fixedly connected between the two pull rods 35.

[0045] During operation, when the grinding is completed, the servo motor 40 is started again, and the servo motor 40 drives the screw 39 to reverse, so that the mounting frame 1 as a whole continues to move toward the direction of the servo motor 40, so that the top plate 33 contacts the support leg 45, and as the mounting shell 2 continues to move, the reaction force of the support leg 45 will cause the T-shaped slide 32 to push the two bottom plates 29 to slide outward through the pull rod 35 at the same time to stretch the tension spring 36, thereby opening the discharge opening 28. When the position of the mounting shell 2 moves to the extreme position toward the servo motor 40, the servo motor 40 is turned off, and the rotation speed of the synchronized first motor 12 is reduced. During the rotation of the circular plate 5, multiple head shells will fall down through the discharge opening 28 into the receiving bottom box 44, thereby achieving the purpose of discharging. When all the discharging is completed, the material can be loaded again.

[0046] For details, see Figure 1-Figure 2 As shown, the lifting assembly includes a limit plate 25, which is fixedly connected to the limit plate 25 on the side wall of the square rod 14 near the top, and 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 limit plate 25, and the other end is fixedly connected to the top of the lifting plate 15. A pulley 27 is installed on the top of the square rod 14, and 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, and 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, and the top of the L-shaped plate 41 is fixedly connected to the bottom of the inner cavity of the reinforcing plate 42.

[0047] During operation, when the pulley 27 rolls to a position close to the loading robot arm 43, it will roll along the inclined surface of the L-shaped plate 41, and the synchronous spring 26 will push the limit plate 25 and the square rod 14 to rise, so that the second grinding brush 20 on the rotating rod 19 will be separated from the vertical tube 10 and rise. Conversely, when the mounting shell 2 moves in the other direction, the pulley 27 will move along the inclined surface at the top of the inner cavity of the L-shaped plate 41, so that the pulley 27 and the limit plate 25 will descend to compress the spring 26, and the synchronous lifting plate 15 and the rotating tube 16 will follow and descend, so that the second grinding brush 20 and the grinding plate 22 will enter the magnetic head housing.

[0048] For details, see Figures 1-10 As shown, the displacement assembly includes a positioning plate 37, and the positioning plate 37 is fixedly connected to the bottom of the mounting shell 2. A screw hole 38 is opened on one side of the positioning plate 37, and a screw 39 is installed in the screw hole 38. The bottom of the mounting frame 1 is symmetrically fixedly connected to the support leg 45, and the two ends of the screw 39 are movably connected to the support leg 45 through bearings. A servo motor 40 is installed on one side of the support leg 45, and one end of the screw 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.

[0049] During operation, the servo motor 40 is started by an external power supply to drive the screw 39 to rotate forward or reverse, so that the positioning plate 37 drives the mounting shell 2 as a whole to move toward the upward feeding robot arm 43 or the servo motor 40, thereby realizing the functions of loading and automatic unloading.

[0050] Among them, the outer wall of the mounting shell 2 is symmetrically fixedly connected with a supporting slider 3, and the inner walls of the mounting frame 1 on both sides opposite to the supporting slider 3 are provided with supporting slide rails 4. One side of the supporting slider 3 extends into the supporting slide rail 4. Through the supporting slide rail 4 and the supporting slider 3, the mounting shell 2 can slide stably without falling. If necessary, grease can be applied to the slide rail to reduce friction and increase service life.

[0051] In addition, grinding discs 30 are fixedly connected to the bottom of the inner cavity of the mounting shell 2 and the top of the bottom plate 29 respectively. The grinding disc 30 is arranged in a ring shape. The bottom of the magnetic head shell can be polished by the grinding disc 30. When the circular plate 5 rotates, the magnetic head shell will be driven to slide on the grinding disc 30, thereby achieving the purpose of polishing.

[0052] Among them, a thread hole 23 is opened on the side wall of the rotating tube 16, and a bolt 24 is installed in the thread 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 thread hole 23 and the bolt 24, so that the rotating rod 19 can be disassembled and installed to facilitate later maintenance and replacement of the second grinding brush 20.

[0053] In summary, the present invention effectively solves the problem that most of the existing magnetic head shell grinding operations still rely on manual operation, which makes it difficult to reach the fine internal parts during manual grinding. In addition, manual operation can only process a single magnetic head shell at a time, resulting in extremely low production efficiency.

[0054] Working principle: When the present invention is used, first place the mounting frame 1 as a whole at the target position, and complete the installation and debugging. It is necessary to program the running trajectory and fixture logic of the loading robot arm 43, and after programming, the loading robot arm 43 can be used in conjunction with the mounting shell 2. After the installation and debugging are completed, if it is necessary to grind the head shell, first start the servo motor 40 through the external power supply to drive the screw 39 to rotate forward, so that the positioning plate 37 drives the mounting shell 2 as a whole to move toward the loading robot arm 43. When the mounting shell 2 is moved toward the loading robot arm 43, When the pulley 27 moves in the direction of 43, it 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 robot arm 43, it will roll along the inclined surface of the L-shaped plate 41. The synchronous spring 26 pushes the limit plate 25 and the square rod 14 to rise, so that the second grinding brush 20 on the rotating rod 19 is separated from the vertical pipe 10 and rises. When the mounting shell 2 moves to the limit position in the direction of the loading robot arm 43, the screw 39 stops rotating. Next, the loading robot arm 43 will clamp the pre-stacked magnetic head shells and place them on the vertical pipes in sequence. 10, and the closed end of the magnetic head housing needs to be placed downward, so that the bottom end of the magnetic head housing will pass through the vertical tube 10 and contact the grinding sheet 30. When the placement is completed, the servo motor 40 is started to drive the screw 39 to reverse, so that the positioning plate 37 and the mounting shell 2 move as a whole toward the servo motor 40. The synchronous pulley 27 moves along the inclined surface of the top of the inner cavity of the L-shaped plate 41, so that the pulley 27 and the limit plate 25 descend to compress the spring 26, and the synchronous lifting plate 15 and the rotating tube 16 follow and descend, so that the second grinding brush 20 and the grinding plate 2 2 enters the magnetic head housing. When 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. The first motor 12 drives the circular plate 5 to rotate as a whole. When the circular plate 5 rotates, because the placement tube 7 is engaged with the fixed gear ring 9, the rotation of the circular plate 5 causes multiple placement tubes 7 to rotate forward at the same time. When the circular plate 5 rotates, it drives multiple magnetic head housings to rotate at the same time. The grinding sheet 30 grinds the bottom of the outer wall of the magnetic head housing, and the rotation of the vertical tube 10 grinds the side wall of the magnetic head housing.

[0055] In order to grind the inner wall of the magnetic head shell at the same time, the second motor 21 is started by an external control power supply, and the second motor 21 drives one of the rotating tubes 16 and the groove wheel 17 to reverse, and the groove wheel 17 drives multiple rotating tubes 16 to reverse synchronously through the synchronous belt 18. The rotating tube 16 drives the rotating rod 19, the second grinding brush 20 and the grinding plate 22 to reverse, so that the second grinding brush 20 can grind the inner wall of the magnetic head shell. In addition, it is important that the second grinding brush 20 and the first grinding brush 11 generate opposite friction forces on the magnetic head shell through the forward rotation of the placement tube 7 and the reverse rotation of the rotating rod 19, so that the magnetic head shell will not rotate in the vertical tube 10, or will rotate slowly, which will not affect the grinding of the magnetic head shell. In addition, when the circular plate 5 rotates, the upper lifting plate 15 is driven to rotate as a whole through the synchronous rod 46, so that the circular plate 5 and the lifting plate 15 can rotate synchronously and in the same direction to avoid jamming.

[0056] When the grinding is completed, the servo motor 40 is started again, and the servo motor 40 drives the screw 39 to reverse, so that the mounting frame 1 continues to move toward the servo motor 40, so that the top plate 33 contacts the support leg 45, and as the mounting shell 2 continues to move, the reaction force of the support leg 45 will cause the T-shaped slide 32 to push the two bottom plates 29 to slide outward through the pull rod 35 at the same time, stretching the tension spring 36, thereby opening the discharge opening 28. When the position of the mounting shell 2 moves toward the limit position of the servo motor 40, the servo motor 40 is turned off, and at the same time The rotation speed of the first motor 12 is reduced in step 1. During the rotation of the circular plate 5, multiple head shells will fall downward through the discharge opening 28 into the receiving bottom box 44 to achieve the purpose of discharging. When all the discharging is completed, the material can be loaded again. The loading can be completed by repeating the above operation. When the mounting shell 2 moves toward the loading robot arm 43, the tension spring 36 will also contract and pull the two pull rods 35 to drive the bottom plate 29 to move toward the center of the mounting shell 2, thereby closing the discharge opening 28. At this time, the T-shaped slide 32 will also slide back to the initial position in the direction of the tension spring 36.

[0057] In this way, more magnetic head shells can be polished reciprocatingly. Because the first polishing brush 11 and the second polishing brush 20 will inevitably wear out after long-term use, which will reduce the accuracy and efficiency of polishing, so if the first polishing brush 11 and the second polishing brush 20 are worn, they can be disassembled and replaced. First, when replacing the first polishing brush 11 and the second polishing brush 20, it is necessary to position the entire mounting shell 2 close to the loading robot arm 43 so that the second polishing brush 20 rises to the limit position. Next, loosen the bolt 24, remove the rotating rod 19 and the second polishing brush 20, and replace the new rotating rod 19. The rod 19 and the second grinding brush 20 are inserted into the rotating tube 16 and the bolt 24 is tightened to fix the rotating rod 19 on the rotating tube 16. When the first grinding brush 11 needs to be replaced, the vertical tube 10 can be directly pulled out from the placement tube 7. Because the vertical tube 10 and the placement tube 7 are slidingly connected, there are slide grooves and sliders between the placement tube 7 and the vertical tube 10, which are used to limit the vertical tube 10 from rotating with the placement tube 7 and to display the position of the vertical tube 10 so that the vertical tube 10 will not fall. Then the new vertical tube 10 and the first grinding brush 11 are placed in the placement tube 7 to complete the replacement, which makes maintenance more convenient.
