In the optical path, they can converge / diverge light rays, separate light beams, reduce stray light, select light rays, reflect light rays, and diverge light beams.

[0003] When particulate impurities are present on the surface of optical components, they can easily affect the performance of the components and cause damage. During the cleaning process, handheld gel cleaning swabs are typically used to manually remove impurities. However, manual cleaning has low utilization rates for the gel cleaning swabs, leading to waste, and gel cleaning swabs are relatively expensive consumables, resulting in high costs for cleaning optical components. Furthermore, manual cleaning of optical components is inefficient and unsustainable, and it is difficult to control the optical components during the manufacturing process.

[0034] To illustrate the technical solution described in this utility model, specific embodiments are described below, showing only the parts related to the embodiments of this utility model.

[0035] Example 1:

[0036] like Figure 1 and Figure 2As shown, this utility model provides an automatic cleaning device for miniature optical components, including a fixed base 1, a cleaning mechanism 2, a vision inspection mechanism 3, and an optical component stage 4. The optical component stage 4 and the vision inspection mechanism 3 are both fixed on the fixed base 1, with the vision inspection mechanism 3 positioned above the optical component stage 4. The optical component stage 4 is used to place at least one component 5 to be cleaned and to adjust the position of the component 5. The vision inspection mechanism 3 is used to identify dirt on the component 5. The cleaning mechanism 2 is movably connected to the arc-shaped guide rail 11 of the fixed base 1. The cleaning rod 21 of the cleaning mechanism 2 is used to remove dirt from the component 5, and the cleaning mechanism 2 can control the cleaning rod 21 to rotate around its axis. Specifically, at least one component 5 is placed on the optical component stage 4. When more than one component 5 is placed, they are arranged in an array on the optical component stage 4. The vision inspection mechanism 3 above the optical component stage 4 is aligned with a device 5 to be cleaned on the optical component stage 4 to obtain the position of a stain on the corresponding device 5 to be cleaned. Based on the relative position information between the end of the cleaning rod 21 and the stain, the amount of movement of the detected device 5 to be cleaned is determined. The optical component stage 4 moves the stain on the detected device 5 to the end of the cleaning rod 21 according to the amount of movement, and the cleaning rod 21 performs adhesive cleaning. After the device to be cleaned 5 is cleaned by the cleaning rod 21, it is moved back to its initial position (i.e., within the shooting range of the vision inspection mechanism 3) by the optical component stage 4. The vision inspection mechanism 3 checks the cleaning effect of the cleaning rod 21. If it is not cleaned properly, the device to be cleaned 5 is moved to the cleaning rod 21 again for cleaning, and the above steps are repeated. During the three cleaning processes of the cleaning rod 21, if the vision inspection mechanism 3 detects that the stain is cleaned, it will clean the next stain on the device to be cleaned 5 or clean the next device to be cleaned 5 according to the above working principle. If the vision inspection mechanism 3 detects that a stain still exists after three cleanings, it will mark the stain as an unwipeable defect and record the device to be cleaned 5 with the unwipeable defect so that subsequent staff can pick it out and ensure that all output products are good products. Once a position at the end of the cleaning rod 21 is utilized, the cleaning mechanism 2 can be rotated along the trajectory of the arc-shaped guide rail 11, and the cleaning mechanism 2 can automatically control the rotation of the cleaning rod 21 to adjust the tilt angle and position of the end side of the cleaning rod 21, thereby making full use of the gel at the end of the cleaning rod 21.

[0037] This utility model utilizes a cleaning mechanism 2 that rotates along an arc-shaped guide rail 11, and an automatic control mechanism 2 that controls the cleaning rod 21 to rotate around its axis, adjusting the tilt angle and orientation of the cleaning rod 21 to improve its utilization rate and reduce costs. A visual inspection mechanism 3 monitors the stains on the device 5 to be cleaned in real time, and an optical component stage 4 adjusts the position of the device 5 to be cleaned, improving cleaning efficiency and controlling the cleaning status of the device 5. This effectively meets the user's needs for low cost, high efficiency, and convenient management.

[0038] As an optional implementation method, such as Figure 4 and Figure 6 As shown, the cleaning mechanism 2 includes a clamping assembly 22, a mounting platform 23, a fixing member 24, and a first motor 25. The first motor 25 is sleeved on the fixing member 24. One end of the mounting platform 23 is fixed to the fixing member 24 by a bearing. The clamping assembly 22 is fixed on the mounting platform 23. The clamping assembly 22 is used to clamp and fix the cleaning rod 21. The first motor 25 is used to drive the mounting platform 23, the clamping assembly 22, and the cleaning rod 21 to rotate. Specifically, the first motor 25 can be a hollow ultrasonic motor, which is convenient to be sleeved and fixed on the fixing member 24. Then, one end of the mounting platform 23 is sleeved on the first end of the fixing member 24 through the bearing. After the first motor 25 is started, it drives the bearing to rotate on the fixing member 24, thereby driving the mounting platform 23, the clamping component 22 fixed on the mounting platform 23 and the cleaning rod 21 clamped on the clamping component 22 to move synchronously. This is used to adjust the side orientation of the end of the cleaning rod 21 so that the gel on the periphery of the end of the cleaning rod 21 can be utilized, so that the cleaning rod 21 can be used multiple times and cleaning costs can be reduced.

[0039] As an optional implementation, the rotation axis of the mounting platform 23 coincides with the axis of the cleaning rod 21. Specifically, the rotation axis of the mounting platform 23 coincides with the axis of the cleaning rod 21, so that when the first motor 25 drives the mounting platform 23 to rotate, the cleaning rod 21 rotates along its axis. This facilitates adjustment of the side orientation of the end of the cleaning rod 21, fully utilizes the gel at the end of the cleaning rod 21, and allows one cleaning rod 21 to clean the cleaning device 5 multiple times, reducing cleaning costs.

[0040] As an optional implementation method, such as Figure 7As shown, the clamping assembly 22 includes a first clamp 221, a second clamp 222, a movable structure 223, an electromagnet structure 224, and a mounting base 225. Both the first clamp 221 and the movable structure 223 are fixed to the mounting base 225, with the movable structure 223 positioned on one side of the first clamp 221. The first clamp 221 has a groove 2211 for accommodating the cleaning rod 21. The second clamp 222 is positioned above the first clamp 221, covering the groove 2211. The second clamp 222 is fixedly connected to the movable structure 223. The electromagnet structure 224 is fixed to the bottom of both the first clamp 221 and the second clamp 222, and is positioned in the middle of the mounting base 225. Specifically, the groove 2211 on the first clamp 221 is used to place the cleaning rod 21. The first clamp 221 and the second clamp 222 cooperate to securely fix the cleaning rod 21 in the groove 2211. Mounting base 225 supports and fixes the first clamp 221 and the second clamp 222 on the moving structure 223, and fixes the clamping assembly 22 on the mounting platform 23. When the electromagnet structure 224 is activated, it can move the second clamp 222 and the moving structure 223, and the moving structure 223 provides moving support for the second clamp 222, thereby opening or closing the groove 2211 between the first clamp 221 and the second clamp 222. When the groove 2211 between the first clamp 221 and the second clamp 222 is opened, the used cleaning rod 21 in the groove 2211 can be replaced; when the groove 2211 between the first clamp 221 and the second clamp 222 is closed, the cleaning rod 21 in the groove 2211 can be locked and fixed.

[0041] As an optional implementation method, such as Figure 7As shown, the electromagnet structure 224 includes a first electromagnet 2241 and a second electromagnet 2242. The first electromagnet 2241 is fixed to the bottom of the first clamp 221, and the second electromagnet 2242 is fixed to the bottom of the second clamp 222. The first electromagnet 2241 is connected to the second electromagnet 2242 via a bearing. The moving structure 223 includes a slide rail 2231 and a slider 2232. The slide rail 2231 is fixed to the mounting base 225, and the slider 2232 is matched with and movably connected to the slide rail 2231. The slider 2232 is fixedly connected to the second clamp 222. Specifically, both the first electromagnet 2241 and the second electromagnet 2242 are sleeved on the bearing, and the first electromagnet 2241 is fixedly connected to the bearing, while the second electromagnet is movably connected to the bearing. When an attractive force is generated between the first electromagnet 2241 and the second electromagnet 2242, they abut against each other. The second electromagnet 2242 drives the second clamp 222 to block the groove 2211 on the first clamp 221. The first clamp 221 and the second clamp 222 cooperate to stably fix the cleaning rod 21 in the groove 2211. When a repulsive force is generated between the first electromagnet 2241 and the second electromagnet 2242, the second electromagnet 2242 slides on the bearing, driving the second clamp 222 away from the first clamp 221, opening the groove 2211 on the first clamp 221, making it easy to replace the new cleaning rod 21. When the second electromagnet 2242 drives the second clamp 222 to move, the two ends of the second clamp 222 slide on the slide rail 2231 through the slider 2232, ensuring the stability of the movement of the second clamp 222.

[0042] As an optional implementation method, such as Figure 7 As shown, the groove 2211 has a V-shaped structure. Specifically, designing the groove 2211 as a V-shape increases the friction between the cleaning rod 21 and the groove 2211, allowing the cleaning rod 21 to better engage and be placed within the groove 2211, preventing the cleaning rod 21 from rotating within the groove 2211. Alternatively, other structures for the groove 2211 can be designed according to requirements, as long as it ensures that the cleaning rod 21 does not move within the groove 2211.

[0043] As an optional implementation method, such as Figure 3 and Figure 5As shown, the cleaning mechanism 2 also includes a six-dimensional force sensing structure 26, a mounting component 27, and a second motor 28. One end of the six-dimensional force sensing structure 26 is fixedly connected to the fixing component 24, and the other end is fixedly connected to the mounting component 27. The six-dimensional force sensing structure 26 is used to detect the pressure applied by the cleaning rod 21 to the device 5 to be cleaned. The mounting component 27 is movably connected to the arc-shaped guide rail 11 via an arc-shaped slider 2232. The second motor 28 is fixed on the mounting component 27, and the transmission wheel 29 on the second motor 28 abuts against the back of the arc-shaped guide rail 11. Specifically, the adjustment platform 42 of the optical component stage 4 moves the dirt on the device 5 to be cleaned, detected by the vision inspection mechanism 3, to below the cleaning rod 21 and abuts against the cleaning rod 21. The adjustment platform 42 drives the device 5 to continue moving towards the cleaning rod 21, generating pressure between the cleaning rod 21 and the device 5 to be cleaned, thereby removing the dirt from the device 5 by the cleaning rod 21. When pressure is generated between the cleaning rod 21 and the device 5 to be cleaned, the six-dimensional force sensing structure 26 can detect the pressure applied by the cleaning rod 21 to the surface of the device 5 in real time, avoiding damage to the device 5 due to excessive pressure. The arc-shaped slider 2232 is matched and movably connected to the arc-shaped guide rail 11. The mounting component 27 is movably connected to the arc-shaped guide rail through the arc-shaped slider 2232, so that the mounting component 27 can drive the six-dimensional force sensing structure 26, the fixing component 24, the first motor 25, the mounting platform 23, the clamping assembly 22, and the second motor 28 fixed on the mounting component 27 to rotate along the trajectory of the arc-shaped guide rail 11. When the mounting component 27 rotates on the arc-shaped guide rail 11, the transmission wheel 29 on the second motor 28 abuts against the back of the arc-shaped guide rail 11. The transmission wheel 29 rubs against the back of the arc-shaped guide rail 11, reducing the rotational speed of the mounting component 27. When the mounting component 27 moves to the target position, the second motor 28 locks and fixes the mounting component 27 through the transmission wheel 29, ensuring the stability of the mounting component 27. This ensures that the cleaning rod 21 is fixed at a certain tilt angle, facilitating the cleaning rod 21 to clean the device 5 to be cleaned. The transmission wheel 29 can be a rubber wheel or a gear.

[0044] As an optional implementation, the center of the arc-shaped guide rail 11 coincides with the end of the cleaning rod 21. Specifically, the center of the arc-shaped guide rail 11 coincides with the end of the cleaning rod 21, so that when the cleaning mechanism rotates along the trajectory of the arc-shaped guide rail 11, the position of the end of the cleaning rod 21 remains unchanged, only the tilt angle between the cleaning rod 21 and the horizontal plane changes. This allows for better utilization of the gel at the end of the cleaning rod 21, improving the utilization rate of the cleaning rod 21 and reducing cleaning costs.

[0045] As an optional implementation method, such as Figure 8 and Figure 9As shown, the optical component stage 4 includes a camera assembly 41, an adjustment stage 42, and a carrier 43. The adjustment stage 42 is fixed on the mounting base 1, the carrier 43 is fixed above the adjustment stage 42, and the camera assembly 41 is fixed to the side of the adjustment stage 42. The adjustment stage 42 is used to move the carrier 43 and the device 5 to be cleaned on the carrier 43 in the X, Y, and Z directions. The camera assembly 41 is used to detect the end of the cleaning rod 21. Specifically, the camera assembly 41 acquires image information of the end of the cleaning rod 21. Through the image information of the end of the cleaning rod 21, it determines the lowest point of the end contour of the cleaning rod 21 in the current state. This lowest point is the position of the stains on the device 5 to be cleaned during this cleaning process, which facilitates the detection and recording of the gel usage at the end of the cleaning rod 21. Therefore, the current state of the cleaning rod 21 can be adjusted according to the gel usage at the end of the cleaning rod 21 to improve the utilization rate of the cleaning rod 21. The current state of the cleaning rod 21 includes the tilt angle of the cleaning rod 21 and the side orientation of the end of the cleaning rod 21. The adjustment table 42 moves the device 5 to be cleaned on the carrier 43 in the X, Y and Z directions according to the needs, so that the device 5 to be cleaned moves back and forth between the visual range of the visual inspection mechanism 3 and the cleaning rod 21, and aligns the device 5 to be cleaned with the visual range of the visual inspection mechanism 3 or the end of the cleaning rod 21, so as to achieve the cleaning effect of the device 5 to be cleaned and to detect the cleaning status of the device 5 to be cleaned.

[0046] As an optional implementation, the end of the cleaning rod 21 is 1mm-5mm away from the visual range of the vision inspection mechanism 3. Specifically, the distance between the end of the cleaning rod 21 and the visual range of the vision inspection mechanism 3 can be selected as 3mm or 5mm. A closer distance between the end of the cleaning rod 21 and the visual range of the vision inspection mechanism 3 can improve the working efficiency of the cleaning device.

[0047] The embodiment is merely a special case and does not indicate that this utility model is implemented in such a way.

[0048] The above description is merely a preferred embodiment of the present utility model. Those skilled in the art will understand that various changes or equivalent substitutions can be made to these features and embodiments without departing from the spirit and scope of the present utility model. Furthermore, under the teachings of the present utility model, these features and embodiments can be modified to adapt to specific situations and materials without departing from the spirit and scope of the present utility model. Therefore, the present utility model is not limited to the specific embodiments disclosed herein, and all embodiments falling within the scope of the claims of this application are within the protection scope of the present utility model.
