Grinding device for lens processing

Abstract

A grinding device for lens processing comprises a first liquid recovery tank, a polishing solution arranged in the first liquid recovery tank, a first polishing disc arranged in the middle of the first liquid recovery tank and at least one circulating pump. The first liquid outlet end of the circulating pump extends to the first polishing disc, so that the polishing liquid in the first liquid recovery tank is recycled and then drips on the first polishing disc for secondary utilization, and on the other hand, the first polishing disc rotates along with the first liquid recovery tank, so that the polishing liquid flowing into the first liquid recovery tank is shaken up, and the polishing effect is improved. Therefore, the situation that the circulating pump is blocked is reduced, and the double-purpose effect is achieved.

[0002] In a lens grinding device, the lens to be ground and polished is usually fixed on a polishing disc, and the polishing disc is driven by a motor to rotate at a certain speed. At the same time, the polishing liquid will flow between the polishing disc and the lens to help remove impurities and scratches on the lens surface. However, there are still the following deficiencies in the actual use process: at present, if the polishing liquid is directly discarded after being used once, it will cause waste. If the polishing liquid can be recycled and reused, the production cost can be effectively reduced. Content of the Utility Model

The lens is arranged on the first machine head. The first liquid recovery tank and the first polishing disc are integrated. The first liquid inlet end of the circulation pump extends below the liquid level of the polishing liquid, and the first liquid outlet end of the circulation pump extends onto the first polishing disc. When the first power mechanism drives the first liquid recovery tank to rotate, the first polishing disc rotates together with the first liquid recovery tank, and the circulation pump transports the polishing liquid from the first liquid recovery tank onto the first polishing disc.

A part of the first liquid outlet pipe is arranged on a part of the first liquid inlet pipe through at least one strap, and the other part of the first liquid outlet pipe extends towards the direction of the first polishing disc.

[0008] In a possible implementation, a second motor is disposed in the base, a cam-linkage assembly is disposed on the base, the second motor drives a part of the cam-linkage assembly to swing, and another part of the cam-linkage assembly drives the first machine head to swing together.

[0009] In a possible implementation, a second guide groove is disposed on the top of the base, and the first liquid recovery tank is disposed in the second guide groove.

[0010] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0011] The structure of the present utility model is simple and practical. On the one hand, by setting the first liquid inlet end of the circulation pump to extend below the liquid level of the polishing liquid in the first liquid recovery tank, and the first liquid outlet end of the circulation pump to extend to the first polishing disc, the polishing liquid in the first liquid recovery tank is recovered and reused by dripping onto the first polishing disc. On the other hand, by setting the first polishing disc to rotate together with the first liquid recovery tank, the polishing liquid flowing into the first liquid recovery tank is shaken evenly, thereby reducing the situation of blockage of the circulation pump, achieving a two-fold effect.
