[0002] Optical lenses are transparent materials made of optical materials such as glass or resin. After being polished, they are used on different equipment or devices to achieve the purpose of protection or to improve the optical effect. During the manufacturing process, optical lenses will be stained with dirt marks formed by difficult-to-wipe objects, so they need to be cleaned. Usually, optical lenses need to be cleaned twice during the production process, after grinding and before coating. The main pollutants in the cleaning after grinding are grinding powder and asphalt, as well as paint flakes that appear in the processing process of a few companies. The main pollutants in the cleaning before coating are edge grinding oil, fingerprints, dust, etc.

[0003] At present, the most common cleaning method is ultrasonic cleaning, which uses the cavitation effect, acceleration effect and straight flow effect of ultrasound in the liquid to directly and indirectly act on the liquid and dirt, so that the dirt layer is dispersed, emulsified and peeled off to achieve the purpose of cleaning. However, because optical lenses are precision components, they must be clamped with a fixture and then carefully cleaned in the solution, otherwise it will cause problems such as edge collapse or incomplete cleaning.

[0004] The current cleaning method generally uses a lens rack to place the optical lenses one by one on the lens rack to clamp and fix them. Then the lens rack is placed in an ultrasonic cleaning device as a whole to clean the lenses with ultrasonic waves and liquid medicine. After cleaning, the lens rack is taken out and the lenses are removed one by one. This method requires the use of a lens rack as a transfer tool to first put the optical lenses in and then take them out after cleaning. This increases the amount of manual labor, increases working time, and reduces efficiency. Therefore, a more automated optical lens cleaning device is needed. Utility Model Content

DETAILED DESCRIPTION

[0020] The technical solution of the present utility model is further described below in conjunction with the accompanying drawings and embodiments.

[0021] like Figure 1 As shown, the embodiment of the utility model proposes an optical lens cleaning device, comprising a bracket 1, a conveyor belt 2 horizontally mounted on the bracket 1, and a cleaning tank 3 arranged below the middle of the conveyor belt 2. In this embodiment, the cleaning tank 3 is a strip-shaped groove corresponding to the direction of the conveyor belt 2, and is arranged just below the conveyor belt 2.

[0022] Specifically, a plurality of telescopic rods 4 are sequentially arranged on the surface of the conveyor belt 2 along the moving direction, and the telescopic rods 4 are vertically fixed on the surface of the conveyor belt 2. Preferably, the conveyor belt 2 in this embodiment is a chain plate structure, so its surface has a certain load-bearing capacity, so that the telescopic rods 4 will not be tilted or offset when fixed on the surface of the conveyor belt 2. The movable end of the telescopic rod 4 is connected to a clamping assembly 5, and the clamping assembly 5 realizes a detachable clamping and fixing of the optical lens. When the telescopic rod 4 moves to the external position of the cleaning tank 3, it can be retracted so that the clamping assembly 5 is higher than the top height of the cleaning tank 3. After the telescopic rod 4 moves to the area corresponding to the cleaning tank 3, it can be extended so that the clamping assembly 5 is completely located inside the cleaning tank 3, thereby realizing the cleaning function.

[0023] The top and bottom of the cleaning tank 3 are respectively provided with a water inlet 31 and a water outlet 32, wherein the water inlet 31 is connected to the cleaning liquid storage tank, and the water outlet 32 ​​is connected to the wastewater treatment tank. It should be noted that in this embodiment, an ultrasonic generator is also provided in the cleaning tank 3 to clean the optical lens immersed in the cleaning liquid by ultrasonic cleaning.

[0024] In a further solution, the clamping assembly 5 includes a fixed plate 51 and a movable plate 52 arranged parallel to each other, the fixed plate 51 is vertically connected to the end of the telescopic rod 4, and the movable plate 52 is movably connected to the fixed plate 51 so that the movable plate 52 can move closer to or farther away from the fixed plate 51, and clamping members are provided on the surfaces of the opposite sides of the fixed plate 51 and the movable plate 52.

[0025] like Figure 2-4 As shown, the clamping member includes a plurality of pressing plates 53 arranged on the fixed plate 51 and a plurality of pads 54 arranged on the movable plate 52. The pressing plates 53 are arranged in a ring shape around the center of the fixed plate 51. The projection of the pressing plates 53 on the fixed plate 51 is arranged along the radial direction of the circular surface formed by the pressing plates 53 and is inclined toward the outside in the direction away from the center of the circle. The pressing plates 53 are elastic sheet structures; the projection of the pads 54 on the movable plate 52 is arranged along the radial direction of the circular surface formed by the pressing plates 53 and is inclined toward the outside in the direction away from the center of the circle. The pressing plates 53 and the pads 54 are arranged alternately in sequence. The lens is fixed by the pads 54 and the pressing plates 53. Since the contact area between the pads 54, the pressing plates 53 and the lens is very small, the cleaning liquid will not be blocked, thereby reducing the cleaning blind area and cleaning the lens more fully and thoroughly. At the same time, the pads 54 and the pressing plates 53 only contact the edge of the lens through points, which is not easy to cause wear to the lens due to vibration, and is safer and more reliable, ensuring the integrity of the lens.

[0026] Preferably, the foot 54 is provided with a plurality of equally spaced blocking heads 541 on the inner side. Therefore, lenses of different diameters can be placed at different heights on the foot 54 by limiting the blocking heads 541, and lenses of different sizes can be fixed and then cleaned by using elastic pressure strips, thereby expanding the applicability of lenses of different sizes. In addition, a circular water-permeable hole 521 is provided in the center of the movable plate 52 or the fixed plate 51, and the water-permeable hole 521 is located inside the circular surface surrounded by the pressing plate 53 or the foot 54. In this way, the cleaning liquid can be more fully and comprehensively contacted with the lens, avoiding that only a small amount of cleaning liquid can clean the surface of the lens, thereby improving the cleaning effect.

[0027] like Figure 2 , Figure 3 As shown, in this embodiment, a plurality of connecting rods 55 are vertically arranged at the edge of the fixed plate 51 or the movable plate 52, the bottom end of the connecting rod 55 is fixed to the top surface of the movable plate 52, and the top end of the connecting rod 55 passes through the fixed plate 51, so that the connecting rod 55 can drive the movable plate 52 to move relative to the fixed plate 51, and a driving mechanism is arranged on the fixed plate 51 to control the movement of the connecting rod 55. Further, the driving mechanism includes a motor 58 and a ball nut 56 arranged on the fixed plate 51, the ball nut 56 is rotatably arranged on the surface of the fixed plate 51, the connecting rod 55 is a screw rod and passes through the ball nut 56 to be connected with the screw rod, the outer edge of the ball nut 56 is provided with teeth to form a gear structure, and a driving gear 57 is arranged on the output shaft of the motor 58, and the driving gear 57 is meshed with the teeth on the outer edge of the ball nut 56. In this embodiment, the ball nut 56 is installed on the top of the fixed plate 51 through a rotating bearing, and the motor 58 is also arranged in parallel on the top of the fixed plate 51. The motor 58 drives the driving gear 57, and then drives the ball nut 56 to rotate. The connecting rod 55 can be controlled to move up and down through the screw transmission, and then the movable plate 52 is driven to move in the vertical direction to adjust the distance between the fixed plate 51 and the movable plate 52.

[0028] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model rather than to limit it. Although the utility model has been described in detail with reference to the preferred embodiments, ordinary technicians in the field should understand that the technical solution of the utility model can be modified or replaced by equivalents without departing from the purpose and scope of the technical solution of the utility model, which should be included in the scope of the claims of the utility model.
