Embodiment 1

[0045] refer to figure 1 and figure 2, is a prism fine polishing device disclosed in the present invention, comprising a frame 1 and a polishing assembly arranged on the frame 1 . The polishing assembly includes a polishing liquid pool 11 for storing polishing liquid provided on the top surface of the frame 1, and the frame 1 is also provided with a spray assembly for spraying the polishing liquid. The shower assembly includes a shower head 14 arranged on the top surface of the frame 1 , and the shower head 14 is located above the polishing disc 2 . The polishing liquid is sprinkled on the polishing disc 2 by pressurizing the water pump to realize heat radiation and cooling of the polishing disc 2 . The supply of polishing liquid also affects the polishing speed. If the supply is too much, the heat generated by polishing will be dissipated rapidly, which is not conducive to the hydrolysis reaction, and the consistency between the mold and the surface of the prism is poor; i...

Embodiment 2

[0052] A kind of prism fine polishing process, it realizes the fine polishing of optical element 6 based on a kind of prism fine polishing equipment in embodiment one, comprises the following steps:

[0053] Step 1: Turn on the spray assembly, spray the polishing solution on the surface of the polishing disc 2 from the nozzle 14, the pH value of the polishing solution is 6.5, and the temperature of the polishing solution is 30°C;

[0054] According to the mass ratio, the content of each component of the polishing liquid is shown in the following table:

[0055] Table 1. Contents of each component of polishing fluid

[0056] components Ceria water Zinc nitrate 10kg 89.5kg 0.5kg

[0057] The polishing liquid can reduce the temperature of the surface of the polishing disc and dissipate the heat generated by polishing. In addition, the polishing powder particles in the polishing liquid can participate in the polishing, which improves the polishing e...

Abstract

The invention discloses a prism fine polishing device, and relates to the technical field of optical lens processing. The prism fine polishing device aims to solve the problems that in a fine polishing process, the temperature is increased, asphalt is softened, and a surface shape of the optical element is not easy to guarantee. According to the technical scheme, the fine polishing device comprises a rack and a polishing assembly, wherein the polishing assembly comprises a polishing solution tank, a rotating main shaft arranged on the top wall of the polishing solution tank, a polishing disc arranged on the top surface of the rotating main shaft and an upper disc attached to the polishing disc; the polishing disc comprises a polishing disc base body and an asphalt polishing module layer, and a plurality of heat dissipation grooves are formed in the asphalt polishing module layer; and the rack is further provided with a spraying component and a pressurizing component for improving the polishing pressure. On one hand, the heat dissipation grooves can dissipate heat to prevent the asphalt from becoming soft, and on the other hand, polishing solution can be uniformly distributed on thepolishing disc; and the polishing solution is sprinkled on the polishing disc through a spray head, so that the heat generated by polishing can be dissipated in time, the asphalt polishing mold layeris not easy to become soft, so that the purpose of improving the precision of the surface shape is achieved.

Description

technical field [0001] The invention relates to the technical field of optical lens processing, in particular to a prism fine polishing equipment and process. Background technique [0002] Polishing is a crucial process in the processing of optical parts. The first step is to eliminate the uneven rough surface and residual damage layer after fine grinding, so that the parts can reach the specified surface finish and surface defect level; Surface trimming to achieve the required aperture number N and local aperture ΔN, and finally form a transparent and regular surface. [0003] The Chinese patent with the publication number CN106736986A of the existing application discloses a polishing method for ED glass lenses. The polishing process is changed from a conventional single polishing to two polishings. First, a polyurethane high-efficiency polishing sheet is used for rough polishing, and then the classical asphalt is used. Polishing mold fine polishing. The advantages of two...
