Description

Technical Field

[0001] The utility model relates to the technical field of glass lens processing, in particular to a glass lens platform surface processing device. Background Art

[0002] For glass lenses with platform surfaces, during the processing process, white spots are usually very likely to appear on the platform surface due to factors such as the material of the lens, the contact pressure between the lens and the grinding wheel during grinding, the grinding time, and the particle size of the grinding wheel (if the particle size of the grinding wheel is large, white spots are easily produced during the grinding process; if the particle size of the grinding wheel is small, it will not be able to grind, or the grinding time is too long, affecting the processing efficiency of the lens). The white spots are usually more obvious after ink coating, affecting the appearance and quality of the lens. Summary of the invention

[0019] like Figure 1-4 As shown, a glass lens platform surface processing device of the utility model comprises a workbench 1, on which a rotating table 2 is arranged, and the rotating table 2 is connected to a motor through a belt. A grinding wheel with a particle size of 1500# is arranged on the rotating table 2; a cylinder 3 is arranged on the workbench 1, and the cylinder 3 is connected to an air source, and a lens fixture 4 is arranged at the end of the piston rod of the cylinder 3; a fixture sleeve 5 for wrapping the lens is also included, and the fixture sleeve 5 is arranged below the lens fixture 4; a spring 6 is arranged on the piston rod of the cylinder 3, and the spring 6 is used to apply pressure to the lens fixture 4 and the fixture sleeve 5. The cylinder 3 is connected to a barometer 8 for monitoring the air pressure change of the cylinder 3. A groove and a water spraying device are arranged on the workbench 1, and the grinding wheel and the water spraying device are arranged in the groove 10, and a drainage pipe can also be arranged below the groove 10. A water spraying device is also arranged on the workbench 1, and the water spraying device can include a nozzle 7 placed in the groove 10, and the nozzle 7 can be connected to a water source through a water pipe. The workbench 1 is provided with a crossbar 9, and the cylinder 3 is provided at the end of the crossbar 9. Figure 1-2As described above, a vertical rod 13 is arranged on the workbench 1, and one end of the horizontal rod 9 is connected to the vertical rod 13 and can rotate with the vertical rod as the axis. The rotation of the horizontal rod 9 can drive the cylinder 3 to move together, so that the cylinder 3 moves to the position of the rotating table to grind the lens. The jig set 5 includes a space for accommodating the lens and a surface matching the lens fixture 4. Specifically, as Figure 4 As shown, the surface is the outer ring plane of the upper surface of the fixture sleeve 5, and the outer ring plane cooperates with the lower part of the lens fixture 4, and is pressed by the lower circumference of the lens fixture 4 when in use, so as to apply force evenly to the lens. A pedal 11 is also provided on the workbench 1, and the pedal 11 is used to control the air source, and then control the air intake of the cylinder 3. After the pedal 11 is released, the air source stops working, and the vacuum negative pressure device 12 works to suck air into the cylinder 3, so that the cylinder 3 does not apply an outward force to the lens fixture 4.

[0020] The utility model is used as the next process of the core extraction device. After the core extraction device roughly processes the platform of the lens, the lens is taken down and placed in the space 51 for accommodating the lens on the jig sleeve 5. Then the jig sleeve 5 is placed under the lens fixture 4, and force is applied upward to compress the spring 6. Then the cylinder 3 is rotated to the top of the rotating table 2 and the force is stopped. Alternatively, the cylinder 3 is first rotated to the top of the rotating table 2, and then an upward force is applied to the lens fixture 4 to compress the spring 6. The space between the lens fixture 4 and the grinding wheel is increased. Then the jig sleeve 5 is placed under the lens fixture 4 and force is stopped; the spring 6 presses the lens onto the grinding wheel. The utility model is aimed at similar Figure 3 The A plane in the lens shown. Before grinding the A plane, step on the pedal 11 to activate the air source, ventilate the cylinder 3, and apply additional pressure to the lens fixture 4, the fixture sleeve 5 and the lens by the piston of the cylinder 3, so that the lens and the grinding wheel are in full contact and the grinding effect is guaranteed. After the grinding is completed, release the pedal 11, and the vacuum negative pressure device 12 will work to control the deflation of the cylinder 3, so that the contact force between the lens and the grinding wheel is only the elastic force of the spring 6. You only need to manually push the lens fixture 4 upward to loosen the contact between the lens and the grinding wheel, so that the lens can be removed easily. Generally speaking, a core extractor reserves a 0.02-0.03mm machining allowance on the platform surface of the lens for rough processing, and then the lens is moved to the utility model for further grinding. Under the premise of a 1500# grinding wheel, the rotation speed is set to 650-700r / min, and the lens is subjected to a pressure of 0.1-0.15mpa. Generally, it only takes 5 seconds to complete fine grinding. Compared with the prior art, which takes 150-180 seconds for the entire processing and has unstable quality, the utility model can save 55-85 seconds in conjunction with the core extractor, which is helpful for improving efficiency and product yield.

[0021] The above is only a preferred specific implementation of the present invention, but the protection scope of the present invention is not limited thereto. Any changes or substitutions that can be easily thought of by any technician familiar with the technical field within the technical scope disclosed in the present invention should be covered by the protection scope of the present invention.
