Description

A slope mechanism for lens cleaning

Technical field

The invention relates to the technical field of optical lens manufacturing, in particular to a bevel mechanism for lens cleaning.

Background technique

The optical lens is generally made of glass or resin, etc. No matter which one is used, the root type is required to be coated with a special-purpose film such as an anti-reflection film, an anti-reflection film, and a reinforcing film. The coating has high requirements on the clean environment and the smoothness and uniformity of the lens surface, and it needs to be cleaned before coating.

Existing cleaning equipment is generally a general cleaning, with conventional liquid washing, ultrasonic cleaning, and even supercritical cleaning. However, the above cleaning method can obtain a better cleaning effect, and may damage the surface of the lens due to a large pressure or vibration. Because the surface of the lens is a weak part, a more gentle cleaning environment and mode are required. At the same time, the cleaning liquid has a low usage rate of one-time washing lens, and if it is directly discarded, it causes waste. Therefore, a recyclable cleaning lens device is required, and at the same time, it has a strong cleaning effect on the lens.

Summary of the invention

OBJECT OF THE INVENTION: In order to clean the lens under mild conditions, to obtain a smooth surface, and to recycle the cleaning liquid, the present invention designs a compact bevel mechanism for lens cleaning to solve the problems in the prior art. .

SUMMARY OF THE INVENTION A beveling mechanism for lens cleaning includes a bevel body and a cleaning liquid tank. The cleaning liquid tank is located above the inclined body. The upper surface of the inclined body is inclined, horizontal and horizontal with an oblique angle to the horizontal. Parallel, the bevel body has a plurality of grooves and a plurality of lower troughs, each of the grooves is distributed from top to bottom along the inclined body, the groove has a set of liquid outlet holes, and the liquid outlet holes are connected to the cleaning liquid through the pipeline a plurality of cleaning tanks are arranged on the trough body; the bevel body is hollow inside, and a filter layer is directly opposite to the lower tank, and a recovery tank is arranged below the screen layer, and the cleaning liquid in the recycling tank is pumped into the cleaning liquid groove.

Preferably, the diameter of the outlet hole gradually decreases from top to bottom along the groove. The lower the gravity effect of the groove, the thicker the liquid layer, which makes the overall uncoordinated and the cleaning efficiency decreases.

Preferably, the cleaning tank is fitted with a cleaning rail, and the cleaning rail carries a lens and moves along the cleaning rail in the cleaning tank. The combination of the track and the groove enables the cleaning of the lens to be arranged in an orderly manner.

Preferably, the ratio of the volume of the recovery tank to the volume of the cleaning liquid in the cleaning liquid tank is 0.85 to 0.92. The volume of the recovery tank ensures that the pump recovery can be started just after the cleaning fluid is consumed in the cleaning liquid tank, ensuring efficiency.

Preferably, the liquid outlet hole has a diameter of 5-12 mm at the upper end of the groove, and the diameter of the liquid outlet hole at the lower end of the groove is 0.5- 0.8mm. The size of the liquid outlet hole ensures the upper and lower distribution of the thickness of the liquid layer and improves the cleaning effect.

Preferably, the flow rate of the liquid in the rinsing device is 0.8-2 m/s, and the thickness of the liquid layer during the flow of the cleaning slant is 1.5-3.5 cm. The liquid flow rate and liquid layer thickness ensure thorough liquid wash.

Preferably, the lower trough and the trough are oriented perpendicular to the washing trough. The vertical sink and the groove are perpendicular to each other to achieve dynamic balance. One side is “leaked” and “washed” on the other side. Similar to the principle of the packed tower, the cleaning tank can be cleaned by passing through it.

Compared with the prior art, the invention has the beneficial effects that the bevel mechanism for lens cleaning of the invention has a simple structure and novel concept. The bevel body and the cleaning liquid tank cooperate with each other, and the liquid outlet hole in the groove is connected to the cleaning liquid tank to achieve the effect of "spraying", and the water falls into the filter layer and the cleaning liquid tank through the lower water tank, thereby entering the recovery tank. Therefore, it can be recovered by the pump, and in order to maintain the flow pattern of the cleaning liquid on the inclined surface, it is inevitable that it is not used once, which improves the utilization rate of the cleaning liquid. The invention has a peculiar concept, and the structure is extremely simple. The result of changing the plane into a slope for cleaning is that the cleaning is mild and does not damage the surface of the lens, and the cycle cleaning process also improves the adjustability of the cleaning parameters and saves cost.
