Description

Technical Field

[0001] The utility model relates to the technical field of clamping and grinding, in particular to a clamping mechanism and a grinding platform. Background Art

[0002] Optical discs are originally transparent polycarbonate particles. These polycarbonate particles are transported to the processing workshop through pipelines, then placed in special containers and melted at high temperatures, and then injected into the mold in proportion. Under high pressure, the melted polycarbonate particles are compressed into a transparent disc shape, which is the disc base. After the disc base is injected, it needs to be polished because before the disc base is pressed against the mother disc to produce the first data surface, a reflective layer of metal material needs to be plated on the base disc. This process is called "sputtering".

[0003] A Chinese patent with publication number CN206839788U discloses a CD base polishing device, comprising a dust suction box and a polishing device, wherein a dust suction and dust collection device is arranged inside the dust suction box, a dust collection outlet is arranged on the side of the dust suction box, a workbench is arranged on the top of the dust suction box, a polishing groove is arranged at the center of the workbench, a fixed seat is arranged at the center of the polishing groove, the fixed seat passes through the center hole of the CD base, an inner base is arranged on the inner side of the CD base, lifting devices are arranged on both sides of the polishing groove, the lifting device is provided with a lifting cylinder and a lifting support plate, the lifting support plate is connected with the polishing device, a polishing motor is arranged on the top of the polishing device, and the motor output shaft at the end of the polishing motor passes through the lifting support plate to be connected to the polishing connecting seat, the polishing disc and the bearing, and the bearing is connected with a fixed suction cup. The utility model has the advantages of stable clamping and polishing, which improves the polishing effect of the CD base, and fixed clamping and polishing work simultaneously, which improves the polishing efficiency of the CD base.

[0004] However, the above-mentioned disclosed solution has the following shortcomings: the above-mentioned device clamps and fixes the optical disc through the structure of the fixed seat, and then grinds the optical disc through the grinder. However, since the powder generated by grinding adheres to the surface of the optical disc and easily affects the subsequent optical disc photolithography processing, it is necessary to discharge the powder generated by grinding during the grinding process to prevent the impact on the optical disc itself.

[0051] The connecting plate 18 is provided with a shell 19, a fixed suction cup 20 is provided on the connecting plate 18, a sliding component 21 is provided on the connecting plate 18, the sliding component 21 includes a sliding telescopic rod 2101, a sliding member 2102 is provided on the sliding telescopic rod 2101, a sliding suction cup 2103 is provided on the sliding member 2102, and a sliding rail 2104 is provided on the connecting plate 18, and the sliding rail 2104 is slidably connected to the sliding member 2102.

[0052] The positioning member 15 is provided with a positioning protrusion, and the surface of the positioning member 15 is provided with an anti-slip layer.

[0053] The sliding suction cup 2103 is provided with an airtight member, and the fixed suction cup 20 is provided with an airtight member.

[0054] A grinding platform comprises any one of the clamping mechanisms described above.

[0055] In this embodiment, the device can effectively improve the efficiency of transporting and polishing optical discs. Compared with traditional devices, the device can effectively prevent dust generated by polishing from affecting the optical disc itself by spraying water during the polishing process. At the same time, the device uses a suction cup to transport the optical disc to avoid squeezing marks on the edge of the optical disc, thereby improving the surface integrity of the raw material.

[0056] When the device is in working state, the device can be adaptively adjusted through the sliding suction cup 2103 according to the diameters of optical discs of different sizes, thereby ensuring the stability of the adsorption force of the device, and the structure of the sliding telescopic rod 2101 can drive the sliding member 2102 to slide. At this time, the mirror sliding component 22 slides synchronously, and the sliding direction of the mirror sliding component 22 is opposite to that of the sliding component 21, so that the fixed suction cup 20 is always in the center position, and the structure of the slide rail 2104 can ensure that the sliding member 2102 will not tilt during the sliding process, thereby ensuring the sliding accuracy of the device, so that the adsorption force of the sliding suction cup 2103 and the fixed suction cup 20 is the same, thereby ensuring that the force on the optical disc is uniform.

[0057] The optical disc is adsorbed by the sliding suction cup 2103 and the fixed suction cup 20, so as to be moved to the top of the positioning member 15. The positioning protrusion on the positioning member 15 can ensure that the center of the optical disc is docked with the center of the positioning member 15, thereby ensuring the rotational stability of the device.

[0058] When the optical disc is mounted on the positioning member 15, the rotating motor 1201 inside the rotating component 12 starts to work. The combination of the transmission belt and the driving wheel 1202 can realize the effect of a single motor driving multiple groups of transmission members 1207 to rotate. The guide wheel 1203 can keep the transmission belt tensioned, avoiding problems such as belt slippage in the device, thereby ensuring the stability of the rotation transmission of the device. The transmission belt can drive the driven wheels 1204 on both sides to rotate, and a driven belt 1205 is provided on the driven wheel 1204 on one side. The driven belt 1205 can drive the rotating wheel 1206 at the center to rotate, thereby ensuring that the rotation speeds of the three groups of transmission members 1207 are the same. The transmission groove 14 structure on the rotating shaft 13 can ensure the stability of the transmission member 1207 to rotate the rotating shaft 13 when the telescopic rod 7 drives the rotating shaft 13 to slide in the vertical direction through the connecting member 8, thereby realizing that the device drives the optical disc to be vertically lifted and lowered while driving the optical disc to rotate at high speed.

[0059] After the rotating shaft 13 drives the optical disc to rotate at high speed, the surface of the optical disc can be polished through the external polishing structure. At this time, the water pump 3 starts to work, and the combination of the water tank 2 and the water pump 3 can spray the cleaning water through the water outlet pipe 5 toward the optical disc, thereby washing away the powder adhered to the surface of the optical disc, thereby avoiding the powder from affecting the subsequent processing of the optical disc surface. After the polishing is completed, the polished optical disc can be adsorbed and transported by the suction cup, thereby realizing the complete processing process of the device. Example

[0060] like Figure 1-Figure 9As shown, the present invention proposes a clamping mechanism and a grinding platform. Compared with the first embodiment, in this embodiment, the structure of the mirror sliding component 22 is the same as that of the sliding component 21, and the sliding direction of the mirror sliding component 22 is opposite to that of the sliding component 21.

[0061] The mirror sliding method can effectively improve the sliding accuracy and stability of the device, ensuring that the fixed suction cup 20 is always in the center position, thereby ensuring that the adsorption force of the device is evenly distributed and reducing the risk of accidental falling of raw materials.
