Description

Technical Field

[0001] This utility model relates to the field of lens cleaning technology, and in particular to a cleaning device for optical lenses. Background Technology

[0002] Optical lenses are transparent optical elements used to change the direction of light propagation, adjust the imaging quality of an optical system, or achieve specific optical functions. They are typically made of glass, optical plastics, or crystal materials. Their main function is to control light through refraction, reflection, or transmission to achieve effects such as focusing, divergence, imaging, filtering, magnification, or reduction. Optical lenses are widely used in optical instruments such as cameras, microscopes, telescopes, eyeglasses, projectors, and laser equipment. They effectively improve image clarity, correct aberrations, and meet the optical performance requirements of different applications. Based on their application and optical characteristics, optical lenses can be classified into various types, including convex lenses, concave lenses, filters, mirrors, and aspherical lenses. Each type of lens plays an irreplaceable role in an optical system.

[0003] After cutting and grinding, optical lenses often retain processing debris, micron-sized particles, and oil stains on their surfaces, requiring specialized cleaning equipment for removal. Currently, most existing optical lens cleaning devices use water rinsing for cleaning. While this method can remove processing residues adhering to the lens surface, its ability to remove micron-sized particles and oil stains is limited, and it cannot perform multiple cleaning cycles, making it difficult to guarantee a high level of cleanliness. This, to some extent, affects the image quality and optical performance of the optical lenses, failing to achieve the ideal cleaning effect, and therefore has certain limitations in its use.

[0004] Based on this, we propose a cleaning device for optical lenses to solve the aforementioned problems. Utility Model Content

[0005] The purpose of this section is to outline some aspects of embodiments of the present invention and to briefly describe some preferred embodiments. Simplifications or omissions may be made in this section, as well as in the abstract and title of the present invention, to avoid obscuring the purpose of these documents, and such simplifications or omissions should not be construed as limiting the scope of the present invention.

[0006] Therefore, the purpose of this invention is to provide a cleaning device for optical lenses that can solve the problem that existing water rinsing methods have limited cleaning ability for micron-sized particles and stubborn oil stains on the surface of optical lenses, and cannot achieve multiple cycles of cleaning.

[0007] To solve the above-mentioned technical problems, this utility model provides a cleaning device for optical lenses, which adopts the following technical solution: it includes a cleaning chamber base, a cleaning tank is installed on the top of the cleaning chamber base, a hoisting assembly is connected to the top of the cleaning tank, a filter screen is also provided at one end of the cleaning chamber base, the hoisting assembly includes a sealing end cap, a centrifugal cleaning component is connected to the bottom of the sealing end cap, and multiple sets of lens bodies are placed on the top of the centrifugal cleaning component.

[0008] Optionally, one end of the cleaning tank base is provided with a liquid inlet, a drain valve is connected to the bottom side of the cleaning tank near the liquid inlet, an ultrasonic generator is connected to one side of the cleaning tank, the ultrasonic generator is installed on one side of the cleaning tank base, and a circulation pump is also provided at the end of the cleaning tank base away from the liquid inlet.

[0009] Optionally, the cleaning tank base has a circulating water tank inside, and a motor drive box is installed on the top of the circulating water tank. The output end of the motor drive box is connected to a transmission flange, which is located inside the cleaning tank.

[0010] Optionally, both ends of the circulating pump are equipped with conveying pipelines, and one end of one set of conveying pipelines is also equipped with a flow guide.

[0011] Optionally, the top of the sealing end cap is provided with a circular groove, which matches the structure of the flow guide shroud. The circular groove and the flow guide shroud are in a transition fit. Several sets of flange holes are provided inside the circular groove, and several sets of seepage grooves are also provided through the outer side of the circular groove near the flange holes.

[0012] Optionally, the centrifugal cleaning component includes a flange connecting frame, with multiple sets of placement trays suspended at the bottom of the flange connecting frame. Multiple sets of lens placement slots are formed around the multiple sets of placement trays. The lens placement slots are matched with the lens body structure and are snap-fitted with the lens body. A fixed flange is also installed at the bottom of the flange connecting frame. The fixed flange is matched with the transmission flange structure and is fixedly connected to the transmission flange.

[0013] In summary, this utility model has at least one of the following beneficial effects:

[0014] 1. The optical lens cleaning device designed in this scheme can perform deep cleaning of lenses through the coordinated operation of a centrifugal cleaning component and an ultrasonic generator. The centrifugal cleaning component rotates at high speed driven by a motor drive box, which can generate strong centrifugal force to effectively remove micron-sized particles and oil stains adhering to the lens surface. At the same time, the high-frequency sound waves generated by the electrically powered ultrasonic generator can create a cavitation effect in the cleaning fluid, which can further loosen and peel off stubborn stains on the lens. This dual cleaning mode can significantly improve the cleaning effect, ensure that the lens surface achieves a high degree of cleanliness, realize the fine cleaning of the lens, and meet the strict requirements of optical lenses for high cleanliness.

[0015] 2. The optical lens cleaning device designed in this scheme, through the combined use of a circulating pump, a filter screen, and a circulating water tank, can achieve the recycling of cleaning fluid, improve cleaning efficiency, and reduce water consumption. The circulating pump can draw the cleaning fluid from the circulating water tank and inject it evenly into the cleaning tank through a guide hood. After the cleaning fluid completes its cleaning task under the action of centrifugal force and ultrasound, it carries impurities into the circulating water tank. The filter screen filters out the impurities, purifying the cleaning fluid so that it can participate in the circulation again. This process not only reduces water waste but also reduces the cost of frequent cleaning fluid replacement, achieving efficient, environmentally friendly, and economical cleaning operations, and fully demonstrating the flexibility and practicality of this device in the field of lens cleaning technology.

[0025] Example: Refer to Figures 1 to 6 This utility model provides an embodiment of an optical lens cleaning device, including a cleaning chamber base 1, a cleaning tank 2 mounted on the top of the cleaning chamber base 1, a lifting assembly 3 connected to the top of the cleaning tank 2, a filter screen plate 4 also provided at one end of the cleaning chamber base 1, the lifting assembly 3 including a sealing end cap 5, a centrifugal cleaning component 6 connected to the bottom of the sealing end cap 5, and multiple sets of lens bodies 7 placed on the top of the centrifugal cleaning component 6. This optical lens cleaning device uses a fixed flange 23 mounted on the bottom of a flange connecting frame 20 and a transmission flange 14 connected to the output end of a motor drive box 13. The transmission flange 14 is located inside the cleaning tank 2, and the fixed flange 23 is fixedly connected to the transmission flange 14. The centrifugal cleaning component 6, which contains multiple sets of lens bodies 7, can be connected and fixed inside the cleaning tank 2. When the motor drive box 13 installed on the top of the circulating water tank 12 is powered on, it can drive the centrifugal cleaning component 6, which has a sealing end cover 5 installed on the top, to rotate inside the cleaning tank 2. When the circulating pump 11 installed at one end of the cleaning tank base 1 is powered on, the cleaning liquid inside the cleaning tank base 1 can be injected into the cleaning tank 2 through the delivery pipeline 15 and the guide shroud 16.

[0026] The cleaning tank base 1 has an inlet 8 at one end. A drain valve 9 is connected to the bottom side of the cleaning tank 2 near the inlet 8. An ultrasonic generator 10 is connected to one side of the cleaning tank 2. The ultrasonic generator 10 is installed on one side of the cleaning tank base 1. A circulating pump 11 is also installed at the end of the cleaning tank base 1 away from the inlet 8. By adding the ultrasonic generator 10 to one side of the cleaning tank 2, the cavitation effect of ultrasound can be used to enhance the cleaning effect, achieving efficient removal of micron-sized particles and oil stains from the surface of the lens body 7. A circulating water tank 12 is provided inside the cleaning tank base 1. A motor drive box 13 is installed on the top of the circulating water tank 12. The output end of the motor drive box 13 transmits... A drive flange 14 is dynamically connected and located inside the cleaning tank 2. By installing a motor drive box 13 on the top of the circulating water tank 12 and connecting its output end to the drive flange 14 inside the cleaning tank 2, power can be provided to the centrifugal cleaning component 6 to drive it to rotate at high speed inside the cleaning tank 2, thereby realizing the centrifugal cleaning function of the lens body 7. Both ends of the circulating pump 11 are equipped with conveying pipes 15, and one end of one set of conveying pipes 15 is also provided with a flow guide shroud 16. Through the cooperation between the conveying pipes 15 and the flow guide shroud 16, the circulating pump 11 can transport the cleaning liquid inside the cleaning tank 1 to the cleaning tank 2.

[0027] A circular groove 17 is provided on the top of the sealing end cap 5. The circular groove 17 matches the structure of the guide shroud 16, and the circular groove 17 and the guide shroud 16 are in a transition fit. Several sets of flange holes 18 are provided inside the circular groove 17. Several sets of seepage grooves 19 are also provided through the outer side of the circular groove 17 near the flange holes 18. Through the cooperation between the circular groove 17, flange holes 18, and seepage grooves 19, the sealing end cap 5 can be used to suspend and connect the centrifugal cleaning component 6 to the bottom of the sealing end cap 5. It also facilitates the even injection of the extracted cleaning water into the cleaning tank 2. The centrifugal cleaning component 6 includes a flange connecting frame 20. Several sets of placement trays 21 are suspended at the bottom of the flange connecting frame 20. Several sets of lens placement grooves 22 are provided around the multiple sets of placement trays 21. Matching the structure of the lens body 7, the lens placement slot 22 and the lens body 7 are snap-fitted together. The bottom of the flange connecting frame 20 is also equipped with a fixed flange 23. The fixed flange 23 and the transmission flange 14 are structurally matched and are fixedly connected. By adding the fixed flange 23 to the bottom of the flange connecting frame 20, and the fixed flange 23 and the transmission flange 14 are fixedly connected, the centrifugal cleaning component 6 can be firmly connected to the transmission flange 14. This ensures that the centrifugal cleaning component 6 can rotate stably and at high speed under the drive of the motor drive box 13, realizing the centrifugal cleaning function of the lens body 7, effectively removing impurities from the lens surface, improving the cleaning effect and cleanliness, and meeting the requirements of optical lenses for high-precision cleaning.

[0028] Working principle: The optical lens cleaning device designed in this scheme mainly consists of a cleaning chamber base 1, a cleaning tank 2, a lifting assembly 3, and a filter plate 4. The lifting assembly 3 includes a sealing end cap 5 and a centrifugal cleaning component 6. The centrifugal cleaning component 6 can be fixedly connected to the transmission flange 14 installed at the output end of the motor drive box 13 by means of the fixed flange 23 at the bottom of the flange connecting frame 20, ensuring that it is stably installed inside the cleaning tank 2. After the lens body 7 is placed in the centrifugal cleaning component 6, a relatively closed cleaning space can be formed by the sealing end cap 5. When the motor drive box 13 is powered on, the centrifugal cleaning component 6 is rotated in the cleaning tank 2 by the transmission flange 14, which can generate centrifugal force, causing the impurities adhering to the surface of the lens body 7 to loosen and fall off.

[0029] The optical lens cleaning device designed in this scheme, when the circulating pump 11 is powered on, can inject the cleaning fluid in the cleaning tank 1 into the cleaning tank 2 through the delivery pipeline 15 and the guide shroud 16, forming a stable cleaning fluid flow, which can rinse the lens body 7. By adding an ultrasonic generator 10 to one side of the cleaning tank 2, the cleaning effect can be further enhanced when the ultrasonic generator 10 is powered on. The high-frequency sound waves generated by the ultrasonic generator propagate in the cleaning fluid and can induce a cavitation effect inside the cleaning tank 2, which can deeply clean the micron-sized particles and oil stains on the surface of the lens body 7. During the entire cleaning process, the cleaning fluid can be recycled after being filtered by the filter screen 4, realizing the high efficiency and environmental protection of the cleaning process.
