Description

Technical Field

[0001] This invention relates to the field of grinding and processing technology, and in particular to a grinding stone tool for grinding hard disk substrates to prevent them from sticking to the disk. Background Technology

[0002] During the grinding process of a hard drive substrate, the grinding tool is softer than the workpiece. During grinding, the abrasive particles are pressed and embedded in the surface of the grinding tool. These relatively hard abrasive particles become countless micro-cutting edges. When the grinding tool and workpiece move relative to each other, some abrasive particles are semi-fixed on the grinding tool, while others slide or roll between the grinding tool and the workpiece, thus uniformly cutting away a very thin layer from the workpiece.

[0003] If waste chips are not cleaned up in time during the grinding process, they will accumulate on the surface of the grinding disc. These accumulated waste chips are easy to mix with the grinding material, and under the action of grinding pressure and friction, they will increase the possibility of the material sticking to the grinding disc. Summary of the Invention

[0004] This invention discloses a grinding stone processing tool for preventing hard disk substrates from sticking to the grinding disk during grinding. It aims to solve the technical problem that if waste debris is not cleaned up in time during the grinding process, it will accumulate on the grinding disk and easily mix with the grinding material, which will increase the probability of the material sticking to the grinding disk.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A grinding stone tool for grinding hard disk substrates to prevent sticking to the disk includes a grinding table. A protective railing is fixedly connected to the top of the grinding table. A motor frame is fixedly connected inside the protective railing. A drive motor is fixedly connected inside the motor frame. The power output shaft of the drive motor is connected to a rotating gear through a coupling. A gear ring is movably connected to the outside of the rotating gear. The rotating gear and the gear ring mesh with each other through tooth grooves. An anti-sticking component is provided inside the gear ring. A grinding disc is provided above the gear ring. A collection component is provided inside the grinding table.

[0007] The anti-stick component includes symmetrical U-shaped plates, with an L-shaped plate fixedly connected to the inner side of one U-shaped plate and an air gun fixedly connected to the inner side of the L-shaped plate. A buffer spring is fixedly connected to the inner side of the other U-shaped plate, and a fixed shaft is fixedly connected to the end of the buffer spring away from the air gun. The outer side of the fixed shaft is movably connected to the inner side of the U-shaped plate, and a vacuum cleaner is fixedly connected to the top of the fixed shaft. The air gun and the vacuum cleaner are symmetrically distributed.

[0008] The collection assembly includes a U-shaped dust collection frame located inside the dust collection box. The top of the U-shaped dust collection frame is fixedly connected to the inner wall of the top of the grinding table. A filter cartridge roller is fixedly connected inside the U-shaped dust collection frame, and a compression rod is installed inside the filter cartridge roller. Both ends of the compression rod are fixedly connected to an automatic rotating rod. Multiple crushing parts are fixedly connected to the outer side of the automatic rotating rod. The outer side of the automatic rotating rod is movably connected to the inner side of the filter cartridge roller.

[0009] In a preferred embodiment, the anti-stick component further includes a ring frame, the outer top of which is fixedly connected to the inner side of the gear ring. The inner side of the ring frame has symmetrical grooves, and a U-shaped plate is movably connected within these grooves. A movable telescopic rod is fixedly connected to the inner side of the L-shaped plate, with the end of the telescopic rod away from the L-shaped plate fixedly connected to the bottom end of the U-shaped plate. A symmetrical connecting frame is fixedly connected to the side of the ring frame away from the drive motor, and rope fasteners are movably connected to the opposite side of the connecting frame. The bottom ends of the symmetrical rope fasteners are fixedly connected to… There is a rotating shaft, and belts are movably connected to the outer side of each rotating shaft. The bottom end of one of the rotating shafts near the jet gun is connected to a servo motor via a coupling. The bottom end of the servo motor is movably connected to the bottom of the grinding table. Pull ropes are wound around the outer side of the symmetrical rope fixing parts. Fixed rope frames are movably connected to the outer side of each pull rope, and connectors are fixedly connected to the outer side of each fixed rope frame. Both ends of the connectors are fixedly connected to one side of the connecting frame. The end of the pull rope away from the rotating shaft is fixedly connected to the opposite side of the symmetrical L-shaped plate.

[0010] Equipped with an anti-stick component, when the grinder begins processing the hard drive substrate and generates debris, the servo motor starts, driving the connected rotating shaft to rotate. The rotation of the rotating shaft causes the symmetrical rope fixing components to rotate, and the pull rope wrapped around the outside of the rope fixing components begins to unwind. As the rope fixing components rotate, the pull rope pulls the L-shaped plate. The movement of the L-shaped plate causes the U-shaped plate to slide within the groove opened on the inner side of the ring frame. During the movement, the air gun and vacuum cleaner remain symmetrically distributed. The movement of the U-shaped plate causes the air gun and vacuum cleaner to slide along the groove within the ring frame, cleaning different locations on the hard drive substrate. During the movement, the air gun sprays air onto the surface of the hard drive substrate, blowing up the debris. The vacuum cleaner, utilizing the elasticity of the buffer spring, adaptively approaches the surface of the hard drive substrate and promptly sucks up the debris blown up by the air gun. In the process, cleaning up the debris can prevent the formation of adhesive substances, thereby ensuring the grinding quality and indirectly reducing material waste and re-grinding due to quality problems, thus improving grinding efficiency.

[0011] In a preferred embodiment, a grinder is fixedly connected to the top of the grinding disc, and the bottom end of the grinder is fixedly connected to the side of the grinding table away from the drive motor. A dust collection box is installed inside the grinding table, and a collection assembly is located inside the dust collection box. An air pump pipe is fixedly connected to the bottom end of the air gun. A cavity is provided inside the grinding table, located behind the dust collection box. The air pump pipe is located inside the cavity, and an air pressure separator is fixedly connected to the bottom end of the air pump pipe. An air pump is fixedly connected to the bottom end of the air pressure separator, and an annular air pump frame is fixedly connected to the outside of the air pump. The annular air pump frame and the cavity... The top inner walls are fixedly connected. A vacuum tube is fixedly connected to the top of the air pressure separator, and the vacuum tube is located above the air pump tube. An air pressure box is fixedly connected to the top of the vacuum tube. A perforation is provided on the grinding table. The outer side of the air pressure box and the inner side of the perforation are fixedly connected. Multiple suction cups are provided on the top of the air pressure box. The suction cups are located inside the ring frame. A telescopic conveying pipe is fixedly connected to the bottom of the vacuum cleaner. A dust inlet is fixedly connected to the bottom of the telescopic conveying pipe. A rectangular hole is opened on the grinding table. The dust inlet is located inside the rectangular hole and fixedly connected. The dust inlet is located above the U-shaped dust collection frame.

[0012] In a preferred embodiment, the collection assembly further includes a power motor. The power output shaft of the power motor is connected to a rotating gear via a coupling. Symmetrical sliding gear rods are movably connected to the outer side of the rotating gear, and the sliding gear rods and the rotating gear are meshed through tooth grooves. The sliding gear rods have sliding holes, and fixed rods are movably connected inside the sliding holes. The bottom ends of the symmetrical fixed rods are fixedly connected to the front ends of the U-shaped dust collection frame. A fixed frame is fixedly connected to the bottom end of the power motor, and the top end of the fixed frame is fixedly connected to the bottom end of the U-shaped dust collection frame. A pulling rod is fixedly connected to the end of the sliding gear rod away from the rotating gear, and a connecting rod is fixedly connected to the end of the pulling rod away from the sliding gear rod. The opposite side of the symmetrical connecting rod is movably connected to the opposite end of the automatic rotating rod. A compression spring is fixedly connected to the front end of the connecting rod, and the opposite end of the compression spring is fixedly connected to both ends of the filter cartridge roller.

[0013] Equipped with a collection component, when waste debris enters the dust inlet through the telescopic conveyor pipe, the motor starts and drives the rotating gear to rotate. The rotating gear meshes with the symmetrical sliding gear rod through tooth grooves. The rotation of the rotating gear drives the sliding gear rod to move linearly along the fixed rod. The fixed rod passes through the sliding hole on the sliding gear rod, guiding the sliding gear rod and ensuring the stability of its linear motion. The pulling rod at the end of the sliding gear rod moves together with the sliding gear rod, driving the connecting rod to move. The connecting rod is connected to one end of the automatic rotating rod, thus causing the automatic rotating rod to move inside the filter cartridge roller. The connecting rod moves, and the compression spring at its front end is stretched or compressed during the rod's movement. When the connecting rod pulls the automatic rotating rod, the compression spring acts as a buffer and reset mechanism, ensuring the smooth movement of the automatic rotating rod. At the same time, the automatic rotating rod itself drives multiple crushing components to rotate, and waste chips fall into the filter cylinder rollers, where the crushing components break them down, reducing larger particles into smaller ones for easier subsequent processing. This process prevents waste chips from entering the precision internal parts of the equipment, thus avoiding accelerated wear and extending the equipment's lifespan. Furthermore, collecting the waste chips makes the working environment cleaner and safer.

[0014] As can be seen from the above, the grinding stone tool for preventing hard disk substrate from sticking to the disk in the grinding process provided by the present invention can clean up the waste chips and avoid the generation of adhesive materials, thereby ensuring the grinding quality. It also indirectly reduces the material waste and re-grinding caused by quality problems and improves the grinding efficiency. Attached Figure Description

The outer side of the fixed shaft 903 is movably connected to the inner side of the U-shaped plate 902. A vacuum cleaner 905 is fixedly connected to the top of the fixed shaft 903. The air gun 908 and the vacuum cleaner 905 are symmetrically distributed.

[0028] The collection assembly 18 includes a U-shaped dust collection frame 1801, which is located inside the dust collection box 19. The top of the U-shaped dust collection frame 1801 is fixedly connected to the inner wall of the top of the grinding table 1. A filter cartridge roller 1813 is fixedly connected inside the U-shaped dust collection frame 1801, and a compression rod 1812 is provided inside the filter cartridge roller 1813. Automatic rotating rods 1809 are fixedly connected to both ends of the compression rod 1812. Multiple crushing parts 1811 are fixedly connected to the outer side of the automatic rotating rod 1809. The outer side of the automatic rotating rod 1809 is movably connected to the inner side of the filter cartridge roller 1813.

[0029] Reference Figure 1 , Figure 3 , Figure 4 , Figure 5 and Figure 6In a preferred embodiment, the anti-stick component 9 further includes an annular frame 901, the outer top end of which is fixedly connected to the inner side of the gear ring 4. The inner side of the annular frame 901 has symmetrical grooves. A U-shaped plate 902 is movably connected inside the grooves. A movable telescopic rod 907 is fixedly connected to the inner side of an L-shaped plate 906. The end of the movable telescopic rod 907 away from the L-shaped plate 906 is fixedly connected to the bottom end of the U-shaped plate 902. A symmetrical connecting frame 910 is fixedly connected to the side of the annular frame 901 away from the drive motor 6. A rope fixing member 912 is movably connected to the opposite side of the connecting frame 910. A rotating shaft 9 is fixedly connected to the bottom end of the symmetrical rope fixing member 912. 11. Belts 909 are movably connected to the outer side of the rotating shaft 911. The bottom end of the rotating shaft 911 near the jet gun 908 is connected to a servo motor 916 via a coupling. The bottom end of the servo motor 916 is movably connected to the bottom of the grinding table 1. Pull ropes 913 are wound around the outer side of the symmetrical rope fixing parts 912.

The end of the pull rope 913 away from the rotating shaft 911 is fixedly connected to the opposite side of the symmetrical L-shaped plate 906.

[0030] Specifically, when the grinding machine 2 starts processing the hard disk substrate and generates waste, the servo motor 916 starts, driving the connected rotating shaft 911 to rotate. The rotation of the rotating shaft 911 drives the symmetrical rope fixing member 912 to rotate, and the pull rope 913 wrapped around the outside of the rope fixing member 912 begins to unwind. As the rope fixing member 912 rotates, the pull rope 913 pulls the L-shaped plate 906. The movement of the L-shaped plate 906 causes the U-shaped plate 902 to slide in the groove opened on the inner side of the ring frame 901. During the movement, the air gun 908 and the vacuum cleaner 905 are always symmetrically distributed. The movement of the U-shaped plate 902 causes the air gun 908 and the vacuum cleaner 905 to slide along the groove in the ring frame 901 to clean different positions on the hard disk substrate. During the movement, the air gun 908 sprays air onto the surface of the hard disk substrate to blow up the debris. The vacuum cleaner 905 uses the elasticity of the buffer spring 904 to adaptively approach the surface of the hard disk substrate and promptly suck up the debris blown up by the air gun 908.

An air pump pipe 12 is fixedly connected to the bottom end of the air gun 908. A cavity is provided inside the grinding table 1, and the cavity is located behind the dust collection box 19.

The top of the air pressure separator 13 is fixedly connected to a vacuum tube 20, and the vacuum tube 20 is located above the air pump tube 12. The top of the vacuum tube 20 is fixedly connected to a pressure box 16. The grinding table 1 is provided with a perforation.

The grinding table 1 has a rectangular hole, and the dust inlet 11 is located inside the rectangular hole and fixedly connected. The dust inlet is located above the U-shaped dust collection frame 1801.

[0032] Reference Figure 2 , Figure 3 , Figure 7 and Figure 8 In a preferred embodiment, the collection assembly 18 further includes a power motor 1805. The power output shaft of the power motor is connected to a rotating gear 1804 via a coupling. Symmetrical sliding gear rods 1803 are movably connected to the outer side of the rotating gear 1804, and the sliding gear rods 1803 and the rotating gear 1804 are meshed through tooth grooves. The sliding gear rods 1803 have sliding holes, and fixed rods 1802 are movably connected inside each sliding hole. The bottom ends of the symmetrical fixed rods 1802 are fixedly connected to the front end of the U-shaped dust collection frame 1801. A fixing frame is fixedly connected to the bottom end of the power motor 1805. 1806, the top of the fixed frame 1806 is fixedly connected to the bottom of the U-shaped dust collection frame 1801, and the end of the sliding gear rod 1803 away from the rotating gear 1804 is fixedly connected to the pulling round rod 1807. The end of the pulling round rod 1807 away from the sliding gear rod 1803 is fixedly connected to the connecting rod 1808. The opposite side of the symmetrical connecting rod 1808 is movably connected to the opposite end of the automatic rotating rod 1809. The front end of the connecting rod 1808 is fixedly connected to the compression spring 1810, and the opposite end of the compression spring 1810 is fixedly connected to both ends of the filter cartridge roller 1813.

[0033] Specifically, when waste chips enter the dust inlet 11 through the telescopic conveyor pipe 10, the power motor 1805 starts and drives the rotating gear 1804 to rotate. The rotating gear 1804 meshes with the symmetrical sliding gear rod 1803 through tooth grooves. The rotation of the rotating gear 1804 drives the sliding gear rod 1803 to move linearly along the fixed rod 1802. The fixed rod 1802 passes through the sliding hole on the sliding gear rod 1803, which guides the sliding gear rod 1803 and ensures the stability of its linear movement. The pulling round rod 1807 at the end of the sliding gear rod 1803 moves together with the sliding gear rod 1803. The pulling round rod 1807 drives the connecting rod 1808 to move. One end of the connecting rod 1808 is connected to the automatic rotating rod 1809, which causes the automatic rotating rod 1809 to move in opposite directions inside the filter cartridge roller 1813. The compression spring 1810 connected to the front end of the connecting rod 1808 is stretched or compressed when the connecting rod 1808 moves. When the connecting rod 1808 pulls the automatic rotating rod 1809 to move, the compression spring 1810 plays a buffering and resetting role to ensure the smooth movement of the automatic rotating rod 1809. At the same time, the automatic rotating rod 1809 itself drives multiple crushing parts 1811 to rotate. Waste chips fall into the filter cartridge roller 1813, where the crushing parts 1811 crush them, breaking larger waste chips into smaller particles for easier subsequent processing.

[0034] Working principle: The grinder 2 drives the grinding disc 3 to grind the hard disk substrate. The pressure box 16 is connected to the pressure separator 13 through the vacuum tube 20. The gas separated by the pressure separator 13 generates air pressure in the pressure box 16. Multiple suction cups 17 at the top of the pressure box 16 are located inside the ring frame 901, which can play a certain role in adsorbing and fixing the hard disk substrate during the grinding process, preventing it from shifting. At the same time, after the drive motor 6 starts, it drives the rotating gear 5 to rotate. Since the rotating gear 5 and the gear ring 4 mesh through the tooth groove, the rotation of the rotating gear 5 will drive the gear ring 4 to make a circular motion. At the same time, the anti-stick component 9 inside the gear ring 4 begins to function. The symmetrically distributed air guns 908 and vacuum cleaners 905 work together. 8. Supported by the L-shaped plate 906, the air pump pipe 12 provides gas pressure. The air pump pipe 12 is connected to the air pump 14. The gas generated by the air pump 14 is separated by the air pressure separator 13 and enters the air pump pipe 12, causing the air gun 908 to spray air onto the surface of the hard disk substrate. At the same time, the vacuum cleaner 905 collects the waste blown off by the air gun 908 through the telescopic conveying pipe 10 and the dust inlet 11 and transports it to the top of the U-shaped dust collection rack 1801. The waste generated by grinding enters the filter roller 1813 in the U-shaped dust collection rack 1801 through the dust inlet 11. Under the rotation of the automatic rotating rod 1809, the waste is further crushed by the crushing part 1811, which facilitates subsequent processing. Larger particles are further crushed by the crushing part 1811 and left in the dust collection box 19.
