Description

Technical Field

[0001] This utility model relates to the field of imaging lens manufacturing technology, and in particular to an imaging lens cleaning device. Background Technology

[0002] Imaging lenses are transparent optical components used in cameras, optical lenses, scanning devices, and inspection equipment to image targets. Their surface cleanliness directly affects image quality and measurement accuracy. In industrial production, optical inspection, and electronic assembly processes, dust, oil, fiber debris, and other contaminants easily adhere to the surface of imaging lenses. These contaminants not only cause blurred images and reduced image resolution but can also affect subsequent coating, assembly, or packaging processes, leading to product scrap and economic losses. Therefore, effective cleaning of imaging lenses is an essential step in optical manufacturing and application.

[0003] In the existing technology, most existing imaging lens cleaning devices adopt a single-blade brush head rotating wiping structure, which has problems such as limited cleaning range, single wiping trajectory leading to local repeated wear, poor adaptability to lens curvature, and easy re-adhesion of dust after cleaning, making it difficult to meet the cleaning requirements of high cleanliness and high efficiency. Utility Model Content

[0004] In view of this, the purpose of this utility model is to propose an imaging lens cleaning device to solve the problems of existing imaging lens cleaning devices having many cleaning dead spots, unstable resetting, and difficulty in adapting to production conditions.

[0005] To achieve the above objectives, this utility model provides an imaging lens cleaning device, including a limiting frame, a cleaning component, and a reset component;

[0006] A cleaning component, located outside the limiting frame, is used for contact cleaning of the imaging lens and for removing debris adhering to its surface.

[0007] A reset component is located on one side of the limit frame and is used to cooperate with the cleaning component to return the cleaning component to its original position after cleaning is completed.

[0008] Preferably, the cleaning assembly includes multiple extension rods that pass through the interior of the limiting frame. A wiping block is fixedly installed on one side of each extension rod. A rotating disk is rotatably installed on one side of the limiting frame. The rotating disk has multiple limiting grooves. A limiting button is fixedly installed at one end of each extension rod and is slidably installed on the limiting groove. A worm gear is sleeved in the middle of the limiting frame and is threadedly connected to the rotating disk. A buffer pad is fixedly installed at one end of the worm gear, and a contact body is fixedly installed on one side of the buffer pad.

[0009] Preferably, the reset assembly includes a fixing frame, which is disposed on one side of the limiting frame. A plurality of telescopic rods are fixedly installed on the fixing frame. The other end of each telescopic rod is fixedly connected to the limiting frame. A reset spring is sleeved on the outside of each telescopic rod. One end of the reset spring is fixed to the fixing frame, and the other end of the reset spring is fixed to the limiting frame. The fixing frame is fixedly connected to the worm gear.

[0010] Preferably, the worm gear has an air hole that passes through the worm gear and the buffer pad and is connected to the contact body, and the air hole is connected to an external air source.

[0011] Preferably, the limiting frame is a five-pointed star shaped part, and each extension of the limiting frame has a sliding groove inside, which is used in conjunction with the extension rod.

[0012] Preferably, the limiting groove is an arc-shaped guide groove, and the limiting groove is radially outward.

[0013] Preferably, the wiping block is an arc-shaped plate-like part, and multiple wiping blocks are gathered together with the contact body to form a complete circle.

[0014] Preferably, the contact body has a porous structure, and the buffer pad is an elastic element.

[0015] The beneficial effects of this utility model are:

[0016] 1. This imaging lens cleaning device, by evenly distributing multiple extension rods and wiping blocks on the pentagonal structure of the limiting frame, and cooperating with the arc-shaped guide groove on the rotating disk and the sliding engagement of the limiting button, enables the wiping blocks to move in a complex radial trajectory during the cleaning process. This ensures full coverage cleaning of the imaging lens surface, reduces lens wear caused by repeated friction, and improves cleaning efficiency and uniformity.

[0017] 2. This imaging lens cleaning device uses a worm gear to drive a rotating disk and connects to an external air source through air holes penetrating the worm gear, buffer pad, and contact body. During the wiping process, it can simultaneously perform airflow blowing or suction cleaning. Combined with the porous structure of the contact body, it not only effectively removes dust and debris from the wiped surface, avoiding secondary pollution, but also, with the elasticity of the buffer pad, prevents the wiping block from scratching the lens, improving the overall service life and reliability of the device. At the same time, it can be installed according to manual or mechanical production to adapt to production conditions. Attached Figure Description

[0027] like Figures 1 to 4 As shown, an imaging lens cleaning device includes a limiting frame 1, a cleaning component, and a reset component;

[0028] Furthermore, such as Figure 1 as well as Figure 4 As shown, the cleaning assembly, located outside the limiting frame 1, is used for contact cleaning of the imaging lens and removing debris adhering to its surface. It includes multiple extension rods 2, which pass through the interior of the limiting frame 1. A wiping block 3 is fixedly installed on one side of each extension rod 2. A rotating disk 4 is rotatably mounted on one side of the limiting frame 1, and the rotating disk 4 has multiple limiting grooves 11. A limiting button 12 is fixedly installed at one end of each extension rod 2, and the limiting button 12 slides on the limiting groove 11. A worm gear 5 is sleeved in the middle of the limiting frame 1, and the worm gear 5 is threadedly connected to the rotating disk 4. A buffer pad 10 is fixedly installed at one end of the worm gear 5, and a contact body 6 is fixedly installed on one side of the buffer pad 10. An air hole 1 is provided on the worm gear 5. 3. The air vent 13 penetrates the worm gear 5 and the buffer pad 10 and connects to the contact body 6. The air vent 13 is connected to an external air source. The limiting frame 1 is a five-pointed star-shaped part. Each extension of the limiting frame 1 has a sliding groove inside. The sliding groove cooperates with the extension rod 2. The limiting groove 11 is an arc-shaped guide groove. The limiting groove 11 is radially outward. The wiping block 3 is an arc-shaped plate-shaped part. Multiple wiping blocks 3 converge with each other and form a complete circle with the contact body 6. The contact body 6 has a porous structure. The buffer pad 10 is an elastic element. Multiple extension rods 2 cooperate with the wiping blocks 3 to achieve multi-point distributed cleaning on the five-pointed star structure of the limiting frame 1. The cleaning range is wide and the cleaning efficiency is high. To improve the overall cleaning efficiency of the imaging lens, the limiting frame 1 adopts a five-pointed star shape design, with a sliding groove at each extension point. This works in conjunction with the extension rod 2, allowing the wiping block 3 to extend and retract stably in five directions. The structure is compact and precisely positioned. The limiting button 12 is slidably mounted on the limiting groove 11 of the rotating disk 4. The arc-shaped radial structure of the limiting groove 11 guides the movement of the extension rod 2, achieving trajectory wiping of the wiping block 3, improving cleaning uniformity and reducing dead zones. The worm gear 5 is threadedly connected to the rotating disk 4. Rotating the worm gear 5 controls the position of the rotating disk 4, enabling the wiping block 3 to advance or retract. Operation is simple and allows for fine stroke adjustment. An air hole 13 is provided in the middle of the worm gear 5, which is connected to an external air source. The air vent 13 penetrates the buffer pad 10 and the contact body 6, enabling it to blow or suck air onto the wiping area, removing dust while wiping, avoiding secondary pollution, and improving the cleaning effect. The buffer pad 10 is an elastic element that provides cushioning force during wiping. Combined with the porous structure of the contact body 6, it prevents the wiping block 3 from scratching the surface of the imaging lens and can adapt to slight curvature changes in the lens. The porous structure of the contact body 6 not only reduces weight but also forms an airflow channel with the air vent 13, enabling airflow-assisted cleaning. The wiping block 3 is an arc-shaped plate-like part. Multiple wiping blocks 3 converge with each other in the working state, forming a complete circle with the contact body 6, ensuring a large cleaning coverage area and high fit.

[0029] Furthermore, such as Figures 1 to 4As shown, the reset assembly, located on one side of the limit frame 1, is used to return the cleaning assembly to its original position after cleaning. It includes a fixed frame 7, which is located on one side of the limit frame 1. Multiple telescopic rods 8 are fixedly installed on the fixed frame 7, with the other end of each telescopic rod 8 fixedly connected to the limit frame 1. A reset spring 9 is sleeved on the outer side of each telescopic rod 8, with one end fixed to the fixed frame 7 and the other end fixed to the limit frame 1. The fixed frame 7 is fixedly connected to a worm gear 5. The fixed frame 7, located on one side of the limit frame 1, provides reliable support for the telescopic rods 8 and the reset spring 9 through stable installation, ensuring reset. The stability and consistency of the operation are ensured by the design of multiple telescopic rods 8, which provide multi-point guidance between the limit frame 1 and the fixed frame 7, ensuring that the cleaning component maintains a stable posture during the reset process and avoids deviation or tilting. A reset spring 9 is sleeved on the outside of the telescopic rod 8, and the two ends of the reset spring 9 are fixedly connected to the fixed frame 7 and the limit frame 1 respectively. After the cleaning component completes the cleaning action, it can automatically drive the rotating disk 4 back to its original position, saving effort and increasing efficiency, and realizing a fully mechanical self-reset. The fixed frame 7 is fixedly connected to the worm gear 5, which ensures the overall rigidity and synchronization of the reset component and the drive system, so that the telescopic and reset actions of the cleaning component driven by the worm gear 5 are coordinated and consistent, and the operation is reliable.

[0030] Example 1: With the cleaning assembly in the retracted state, multiple wiping blocks 3 are separated from the contact body 6 by the reset spring 9 in the reset assembly. The limiting frame 1 is stably positioned by the fixing frame 7 and the telescopic rod 8. At this time, the operator picks up the imaging lens and presses the contact body 6, thereby driving the worm gear 5. The worm gear 5 is threadedly connected to the rotating disk 4, causing the rotating disk 4 to rotate. The limiting groove 11 on the rotating disk 4 is an arc-shaped guide groove. The limiting button 12, which is fixedly installed at one end of the extension rod 2, is slidably installed in the limiting groove 11. As the rotating disk 4 rotates, the limiting groove 11 guides the limiting button 12 to move outward radially, pushing the extension rod 2 inward. The wiping block 3 closes and, driven by the rotating disk 4, wipes and cleans the surface of the imaging lens along a predetermined trajectory. During the wiping process, the air hole 13 on the worm gear 5 is connected to an external air source. The airflow passes through the air hole 13, through the buffer pad 10, and is ejected (or sucked in) by the contact body 6. In conjunction with the wiping action, the dust on the lens surface is blown or sucked away while wiping, avoiding secondary pollution and improving the cleaning effect. After cleaning, the lens is removed, and the reset spring 9 in the reset assembly, guided by the telescopic rod 8, drives the worm gear 5 to drive the rotating disk 4 back to its original position. The wiping block 3 unfolds under the guidance of the limiting groove 11, disperses again, and returns to the standby state, ready for the next cleaning.

[0031] Example 2: The device can be installed on the production line. The wiping block 3 is placed with one side facing the lens to be cleaned or the lens that has been produced. When the lens passes in front of the device, the push rod and other workpieces behind it are controlled by the PLC to perform a pushing action, driving the lens to approach the contact body 6 until it presses the contact body 6 to drive the worm gear 5 to the position, and perform the action in Example 1. After completion, the lens or lens product is moved out by the push rod through the control components such as the PLC, and the cleaning work is completed.
