[0035] Embodiment

[0036] The embodiment provides a polishing device for optical element production, as shown in the accompanying drawings, comprising: Figures 1-4

[0037] A polishing turntable 1;

[0038] A workpiece fixing base 2 is fixed on the polishing turntable 1, used for mounting a workpiece 5 to be polished, and a workpiece fixing groove 4 is arranged in the workpiece fixing base 2 to facilitate polishing of the workpiece, and other existing structures can also be arranged to cooperate to realize fixation of the workpiece;

[0039] A polishing disc 6 is arranged above the workpiece fixing base 2, tightly adheres to the workpiece 5 to be polished during polishing, and a plurality of liquid outlets 606 are formed in the bottom of the polishing disc 6.

[0040] A polishing liquid collecting groove 3 is arranged between the polishing turntable 1 and the workpiece fixing base 2, and the polishing liquid collecting groove 3 is connected with a polishing liquid storage device 9 through a bottom outlet.

[0041] ​In use, the workpiece to be polished is placed in the workpiece fixing base 2, and the polishing disc 6 is pressed down to fit tightly against the workpiece. When the equipment is started, the polishing disc 6 and the polishing turntable 1 rotate in opposite directions. The polishing liquid storage device 9 supplies polishing liquid to the polishing disc 6. The polishing liquid flows out from the bottom outlet 606 of the polishing disc 6 and comes into contact with the workpiece to be polished. During the centrifugal rotation process, some of the polishing liquid is thrown out. At this time, due to the presence of the polishing liquid collection tank 3, the thrown-out polishing liquid flows into the polishing liquid collection tank 3, and then flows into the polishing liquid storage device 9 through the bottom outlet of the polishing liquid collection tank 3, thereby realizing the recycling of polishing liquid and reusing the polishing liquid, reducing the loss of polishing liquid and reducing production costs. At the same time, since the polishing liquid flows out through the outlet 606 of the polishing disc 6, the polishing liquid can be distributed on the surface of the component to be polished during polishing, avoiding the uneven distribution problem caused by the spraying of polishing liquid in the prior art, and improving polishing efficiency.

[0042] See Figure 1 The polishing turntable 1 is a circular turntable with an annular flange at its edge. The height of the flange is higher than the height of the workpiece fixing base 2. In this way, during the polishing rotation, the flange can block and collect the polishing liquid that is thrown out, preventing the polishing liquid from splashing out.

[0043] See Figure 1 and Figure 4 The workpiece fixing base 2 has a drainage channel 201 on its side, which connects the workpiece fixing groove 4 and the polishing liquid collection tank 3. By providing a drainage channel 201 on the side of the fixing base, it is convenient to discharge and recycle the polishing liquid remaining inside the workpiece fixing base 2. Preferably, the drainage channel 201 is inclined, with the higher end connecting to the inside of the workpiece fixing groove 4 and the lower end connecting to the polishing liquid collection tank 3, so that the polishing liquid can automatically flow into the polishing liquid collection tank 3.

[0044] See Figure 1 and Figure 3 The polishing slurry collection tank 3 has several collection ports 301 at its bottom. These collection ports 301 are connected to a collection channel 101 inside the polishing turntable 1, and the collection channel 101 is connected to the polishing slurry storage device 9. Polishing slurry is easily collected through the collection ports 301 and flows out from them. The collection channel 101 connects the collection ports 301, facilitating the concentration of polishing slurry.

[0045] The collecting channel 101 is connected with the polishing liquid storage device 9 through the collecting pipe 7, and the filtering device 8 is arranged on the collecting pipe 7.

[0046] The inlet end of the polishing liquid storage device 9 is connected with the collecting channel 101 through the collecting pipe 7, and the outlet end of the polishing liquid storage device 9 is connected with the sample inlet of the polishing disc 6 through the conveying pump 10 and the liquid conveying pipe 11.

[0047] Referring to Figure 2 The polishing disc 6 has a body 601, and the body 601 is internally provided with a liquid storage cavity 604, and the liquid storage cavity 604 is communicated with the liquid outlet 606 arranged at the bottom of the polishing disc 6.

[0048] As shown in Figure 2 Figure 2 The liquid outlet channel 605 penetrates through the bottom of the liquid storage cavity 604, the elastic layer 602 and the polishing layer 603, wherein the body 601 is made of rigid material, the elastic layer 602 is made of rubber material, and the body 601 can tightly adhere the polishing layer 603 to the element to be polished under the action of external force, and when the surface of the element to be polished is uneven, the elastic layer 602 can ensure that the polishing layer 603 is tightly adhered to the element to be polished through deformation, thereby ensuring the polishing quality.

[0049] Finally, it should be noted that: the above specific embodiments are only used to specifically describe the purpose, technical scheme and beneficial effects of the present application, and should be understood that the above description is only a specific embodiment of the present application, and is not used to limit the protection scope of the present application; although the present application is described in detail with reference to the foregoing specific embodiments, those skilled in the art should understand that: it can still modify the technical scheme recorded in the foregoing embodiments, or make equivalent replacement, improvement, etc. to part or all of the technical features; and these modifications, equivalent replacement, improvement do not make the essence of the corresponding technical scheme deviate from the scope of the technical scheme of the embodiments of the present application, and they should be covered in the scope of the claims and the specification of the present application.
