Description

Technical Field

[0001] The present invention relates to the field of camera lens maintenance, and in particular to a repair method and a processing device for a hydrophilic film layer of a camera. Background Art

[0002] A key prerequisite for autonomous driving perception is ensuring that the path through which the vehicle's external sensors receive environmental signals is protected from unexpected obstructions such as rain, snow, dust, leaves, and insects. Ensuring the safety of autonomous driving systems requires both increased redundancy and ensuring that sensors can properly acquire environmental information.

[0003] Currently, the most pressing issue is reducing the impact of rain and similar conditions on autonomous driving perception (such as obstructed vision, intense glare, and ghosting). (Super) hydrophilic coatings are a relatively effective approach. Using an ultra-small drop angle (less than 5°), water droplets quickly spread across the surface, forming an ultra-thin, uniform film that keeps the surface clean. This can significantly improve vision, for example, in rainy and nighttime driving, and enhance driving safety. However, for automotive-grade applications, these coatings also present certain durability issues.

[0004] Of course, in addition to the field of autonomous driving, similar situations also exist with shooting devices such as sports cameras and outdoor cameras.

[0005] Based on the current hydrophilic coatings on the market, combined with the results of high- and low-temperature durability and UV aging tests, the possibility of developing a permanent coating (maintaining a lifespan of more than 10 years) is not very high. However, when the (super) hydrophilic coating's effectiveness fades or fails, a series of procedures at a car maintenance center to reapply a hydrophilic coating may be a novel approach. Summary of the Invention

[0006] The purpose of the present invention is to provide an after-sales maintenance process for the hydrophilic film layer of a shooting device, which avoids the defect that permanent coating is difficult to develop, and the repaired hydrophilic film layer has strong adhesion and high reliability.

[0007] In addition, the present invention is also intended to solve or alleviate other technical problems existing in the prior art.

[0023] Optionally, according to one embodiment of the present invention, the inspection method of step S4 or step S5 is: applying water to the surface of the lens, observing the water adhesion on the surface, if water droplets hang on the surface, it means that the function of the hydrophilic film layer has failed; if the water forms a uniformly spread water film on the surface, it means that the function of the hydrophilic film layer is effective.

BRIEF DESCRIPTION OF THE DRAWINGS

[0032] The above and other features of the present invention will become apparent with reference to the accompanying drawings, in which:

[0033] Figure 1 A schematic cross-sectional view of a lens of a shooting device according to the present invention is shown;

[0034] Figure 2 A flowchart showing a repair method according to the present invention; and

[0035] Figure 3 A structural diagram of a processing device according to the present invention and an application example are shown. DETAILED DESCRIPTION

[0036] It is easy to understand that according to the technical solution of the present invention, without changing the essential spirit of the present invention, a person skilled in the art can propose a variety of interchangeable structural modes and implementation modes. Therefore, the following specific embodiments and drawings are only exemplary descriptions of the technical solution of the present invention and should not be regarded as the entire invention or as a limitation or restriction of the technical solution of the present invention.

[0037] The terms "up," "down," "left," "right," "front," "back," "front," "back," "top," and "bottom" mentioned or potentially mentioned in this specification are defined relative to the structures shown in the accompanying drawings. They are relative concepts and may vary depending on their location or usage. Therefore, these or other directional terms should not be interpreted as restrictive. In addition, the terms "first," "second," "third," and similar expressions are used only for descriptive and distinguishing purposes and should not be understood to indicate or imply the relative importance of the corresponding components.

[0038] refer to Figure 1 , which shows a cross-sectional schematic diagram of a lens of a shooting device according to the present invention.

[0039] The shooting device has a lens 1, which can be an optical lens, having a lens group and a lens barrel 12, wherein the lens group is at least partially assembled in the lens barrel 12, and the lens group has a plurality of lenses (five lenses are shown exemplarily in the figure), wherein the lens 11 exposed to the external environment is exemplarily located on the leftmost side in the figure, and can also be regarded as the lens at the frontmost side when the lens 1 is in use. It should be noted that the optical lens can be understood as the head part of the entire shooting device, and can also be broadly understood as a camera. The optical lens can be, for example, a component of a car camera, a surround-view camera, a sports camera, a film and television camera, a drone camera, an outdoor camera, etc. There is no special restriction on the field (such as a car camera), and there is no special restriction on the structure of the shooting device.

[0040] As for the structure of the lens 1, it can also be seen that the lens 1 also has a spacer 13, a color filter 14, a pressure ring 15, and a waterproof ring 16, wherein the spacer 13 is arranged between the first two lenses. Of course, corresponding spacers can be provided between each lens of the lens group to provide corresponding fixing and separation functions for each lens; the color filter 14 is provided in the lens barrel 12 and is arranged at the end portion at the rear side when the lens 1 is in use. The color filter 14 can be a colored transparent sheet that has the functions of absorbing, reflecting and transmitting colored light, and it also This can be referred to as a color filter or a color filter. In this example, the color filter 14 is plate-shaped and embedded in a groove provided for this purpose in the lens barrel 12. The pressure ring 15 has a vertical extension on its left side for securing the lens 11. Furthermore, the pressure ring 15 has a horizontal extension on its right side for connecting to the lens barrel 12, such as by threaded locking. The pressure ring 15 is located radially outward of the entire lens 1, protecting the components within it and ensuring assembly and stability. The waterproof ring 16 rests between the lens 11 and the lens barrel 12. All components of the lens 1, except the pressure ring 15, are stacked, resulting in a very compact lens 1, requiring minimal space, and maintaining a stable overall structure. Stacking means that each component is always in direct contact with at least one adjacent component. Furthermore, the number of optical lenses and spacers can be variable; for example, n+1 optical lenses and n spacers can be included, where n is 0 or a positive integer.

[0041] Since the focus of the present disclosure is not on the structure of the lens itself, only a brief exemplary introduction to the structure is given.

[0042] refer to Figure 2 , which shows a flowchart of a repair method according to the present invention. The upper rounded rectangle indicates the start, the lower rounded rectangle indicates the end, Y represents a yes judgment, N represents a no judgment, and DN represents a Double No, meaning the second judgment result is still no. The specific meaning of the second judgment can be understood from the following description of the repair method.

[0043] The repair method is used for a hydrophilic film layer (or coating) of a camera device, wherein the hydrophilic film layer is provided on the surface of the lens 11, wherein the repair method comprises the following steps:

[0044] S1: Cleaning the lens 11;

[0045] S2: Exciting the active groups on the surface of the lens 11;

[0046] S3: applying a hydrophilic film repair solution onto the surface of the lens 11 .

[0047] It should be noted that the naming of the various method steps in this article is only for the purpose of distinction and convenience of reference, and does not necessarily mean that there is a difference in the order of these method steps (unless explicitly stated). They can be adjusted in order of implementation according to actual circumstances, or even executed simultaneously.

[0048] The concept of hydrophilic mentioned in this article should be understood in a broad sense, which also covers characteristics such as super-hydrophilicity. In fact, as long as the film layer or material on the surface of the lens on the front side of the shooting device can be used to spread water droplets into a film to keep the lens surface clean, it is within the scope that the hydrophilic film layer can cover. It should be understood that the cleaning of step S1 is mainly used to remove oil, dirt, etc. on the surface of the lens 11, paving the way for subsequent steps. A detergent can be used to clean the surface of the camera lens. In the excitation of step S2, taking the lens 11 as a glass lens as an example, this step refers to stimulating the active groups of silicon oxide in the glass as the substrate. This step can make the hydrophilic film repair solution more firmly adhere to or stick to the substrate, thereby enhancing the durability and reliability of the repaired hydrophilic film layer.

[0049] It can be imagined that since the original position of the hydrophilic film layer is on the outer surface of the lens 11, the maintenance process of the entire camera hydrophilic film layer can only be targeted at the outer surface of the lens 11, so as to achieve the expected maintenance purpose and effect at a low cost based on actual conditions.

[0050] In an optional embodiment, in step S2, a plasma surface treatment process is employed to excite reactive groups on the surface of the lens 11. For example, the plasma surface treatment process can utilize a low-temperature plasma process, allowing the lens 11, or even the entire lens, to be uniformly and effectively treated, thereby stimulating reactive groups on the surface of the substrate used for the original film layer. Furthermore, plasma surface treatment improves surface spreading properties, preventing the formation of bubbles, and simultaneously enhances the quality of the lens or lens at a lower cost and with higher efficiency.

[0051] In step S3, the hydrophilic film repair solution (also referred to as a spray solution if spraying is used) is the raw material for hydrophilic film repair. The raw material can be an inorganic material system, an organic material system, or a mixture of the two, and can be applied in various ways. Exemplarily, the inorganic material of the hydrophilic film repair raw material is nano-silicon oxide or nano-titanium oxide; the organic material is fluorine-containing organic compound or organosilicon material.

[0052] For example, in step S3, the hydrophilic film repair solution is applied by atomized spraying, for example, by converting a pressurized liquid into an aerosol for spraying. This aerosol adheres very evenly to the lens surface, forming a thin, smooth film. Furthermore, atomized spraying is well-suited for after-sales repair work, as the airflow can be controlled to be small (easily forming a mist), which minimizes the impact on the object being applied.

[0053] It should be understood that the after-sales maintenance process of the hydrophilic film layer of the shooting device according to the main technical solution of the present invention avoids the defect that permanent coating is difficult to develop, and the repaired hydrophilic film layer has stronger adhesion and higher reliability.

[0054] It can also be seen from the exemplary method shown in the figure that the repair method further includes the following steps:

[0055] S4: performing a pre-inspection on the hydrophilic film layer of the lens 11 to determine whether the original function of the hydrophilic film layer has failed;

[0056] S5: Perform a post-inspection on the hydrophilic film layer of the lens 11 to determine whether the function of the repaired hydrophilic film layer is effective.

[0057] Among them, step S4 is located before step S1, and step S5 is located after step S3.

[0058] Thus, the pre-inspection step can determine in advance whether the existing hydrophilic membrane is still usable. If it is, subsequent repair work can be avoided, thus avoiding the risk of increased after-sales maintenance costs and allowing the hydrophilic membrane to fully function and maintain its lifespan. If it is no longer usable, subsequent repair work can be performed. Of course, even then, users can still choose to repair the membrane as needed or desired to achieve optimal hydrophilic membrane condition. In contrast, the post-inspection can be considered a verification process to prevent the hydrophilic membrane from remaining functionally inoperable after the repair process. It should be noted that functional failure should be understood broadly. Any inability to achieve its intended purpose (for example, spreading rainwater to form a water film) can be considered functional failure, and functional degradation can also be a manifestation of functional failure. If the post-inspection determines that the hydrophilic membrane is effective, maintenance can be completed.

[0059] Further, if it is determined in the post-inspection of step S5 that the function of the repaired hydrophilic film layer is invalid, the repair method is re-executed from step S1, and after re-execution, if it is again determined in the post-inspection of step S5 that the function of the repaired hydrophilic film layer is still invalid, the repair method executes step S7: replacing the lens 1.

[0060] Through the above-described technical solution, one embodiment of the present disclosure provides two corresponding approaches to address the situation where the hydrophilic film layer is still found to be defective after post-inspection. Specifically, if the hydrophilic film layer is still defective after the first repair process (or step S3 or step S6 (described below)), the repair method will be re-executed starting from the cleaning step, i.e., the repair will be attempted again to ensure that the method is executed flawlessly. In this case, if the hydrophilic film layer is still defective after the second post-inspection, the repair method starting from the cleaning step will not be re-executed. This is because, even if the repair method has been fully implemented, the hydrophilic film layer is still not effective. This essentially indicates a high probability of a problem with the lens itself (such as damage to the lens surface, such as scratches). Therefore, the response is changed to step S7: replacing the lens 1. If necessary, the entire camera device can also be replaced in this step. The new lens or lens of the camera device can be equipped with a brand new hydrophilic film layer.

[0061] In addition, after replacing the lens 1 or the shooting device, those skilled in the art should be aware that recalibration should be performed when necessary based on the original usage scenario of the lens or shooting device. In this regard, it should be understood that for the lens or shooting device itself, the so-called calibration refers to solving the relevant shooting parameters or imaging geometric model, with the purpose of helping to use the image captured by the camera to truly restore the objects in space. If the camera itself needs to work in conjunction with other cameras (such as a system with multiple shooting devices), then in addition to its own calibration, it is also necessary to recalibrate the camera in conjunction with other cameras to ensure that the camera and other cameras can work together and "fuse" well, so as to output data or information that can be integrated.

[0062] Regarding the specific implementation of the pre-inspection and post-inspection, for example, the inspection method of step S4 or step S5 is: water is applied to the surface of the lens 11 and the water adhesion is observed. If water droplets are attached to the surface, it indicates that the hydrophilic film layer has failed to function; if the water forms a uniform film on the surface, it indicates that the hydrophilic film layer is effective. Ordinary clean water can be used, for example, and the water adhesion is observed after 5 to 10 consecutive applications (e.g., spraying). This can more economically and realistically simulate the hydrophilic film layer's ability to handle actual conditions.

[0063] It should be understood that, for example, in an automotive application, the vehicle is first driven into a maintenance center. Once the vehicle passes the inspection in step S3 or steps S4 and S5, the maintenance work is completed. Of course, other maintenance items can be performed before, after, or simultaneously with the maintenance. Once all items are maintained, the entire maintenance work can be considered complete.

[0064] In some embodiments of the present disclosure, the repair method further includes the following steps:

[0065] S6: heating the lens 11 to accelerate the reaction and solidification of the applied hydrophilic film repair solution.

[0066] Wherein, step S6 is located after step S3.

[0067] As can be seen from the above, the heating and curing process can accelerate the reaction speed of the hydrophilic film repair solution applied (for example, by atomization spraying), and shorten the entire construction time. It should also be understood by those skilled in the art that if the post-inspection step S5 is also adopted, step S6 can be placed between step S3 and step S5, for example, as Figure 2 As shown by way of example.

[0068] refer to Figure 3 , which shows a structural schematic diagram and application example of a processing device according to the present invention.

[0069] The processing device 100 is used for photographing the hydrophilic film layer of the device, wherein the processing device 100 is used to perform step S3 of the above-mentioned repair method and / or to perform step S4 and / or step S5 of the above-mentioned repair method, and the processing device 100 has:

[0070] A liquid storage container 101, in which a hydrophilic membrane repair solution or water can be stored;

[0071] a nozzle 102 , which is in communication with the liquid storage container 101 and is capable of atomizing and spraying the liquid stored in the liquid storage container 101 onto the surface of the lens 11 ; and

[0072] The fixing structure 103 is used to fix the lens 1 . The fixing structure 103 is disposed at the liquid storage container 101 or the nozzle 102 .

[0073] According to the above technical solution, the processing device 100 can perform two functions for the hydrophilic coating of a camera device: repair and inspection. Of course, it can selectively perform one of these functions. For the repair function, the liquid reservoir 101 is used to store a hydrophilic coating repair solution (also known as a coating solution or spray solution); for the inspection function, the liquid reservoir 101 is used to store water, such as ordinary water. Furthermore, the function of the fixing structure 103 ensures the consistent position of the nozzle 102 and the lens 1. During the atomization spraying process, the nozzle 102 maintains a stable relative position to the lens 1 or lens. This facilitates the control of the application parameters of the repair solution (e.g., application speed, angle, force, etc.) and the characteristics of the hydrophilic coating (e.g., reflectivity), ensuring uniformity. Furthermore, it is understood that, to accommodate various lens 1 or lens sizes, the fixing portion of the fixing structure 103 can be sized to match the surface of the camera. In particular, the fixing portion is adjustable to enhance its compatibility with different cameras or lenses. In this example, the fixing structure 103 is used to fix to the pressure ring 15 of the lens 1. Of course, the fixing structure 103 can also be fixed to other parts of the lens 1 as long as the stability is guaranteed. In addition, the fixing method can be diversified or a combination of multiple methods, such as snap fastening, threaded fitting, bonding, and other detachable fixing methods.

[0074] Therefore, for inspection purposes, the processing device 100 used is newly customized for the camera. Regardless of the camera's fixed position, this processing device 100 can easily and quickly inspect the original film's effects. Furthermore, for repair or atomized spraying, after the plasma treatment is complete, the newly customized processing device 100 can be immediately fixed to the camera (at a fixed spray distance) and continuously sprayed (e.g., by pressing) to evenly spread the hydrophilic film repair solution across the camera lens surface. This atomization device is simple, portable, and ensures consistent results.

[0075] Here, the liquid storage container 101 is a cylindrical bottle with a simple structure and high cost-effectiveness, and the nozzle 102 is also generally cylindrical in shape. In particular, the liquid storage container 101 can be constructed as a pressurized bottle that can discharge liquid by pressing. As a result, the application of the repair solution can also be conveniently performed automatically or manually. Therefore, the liquid storage container 101 can also be regarded as a spray bottle or a spray bottle. On the one hand, it has the function of holding the solution, and on the other hand, it also provides a pressing function, and the pressure generated ensures that the solution in the bottle can reach the nozzle and thereby be atomized into small droplets. The material of the spray bottle is generally transparent PET / PP / ABS, which is relatively common and easy to obtain and use. Of course, other materials are also possible. In addition, the pressing force can be selected, for example, between 1 and 30 N, which can achieve the desired spraying effect in an economical and labor-saving manner. In particular, the press spraying method can better ensure the consistency of the discharged liquid and the hydrophilic film layer after repair, and ensure that the reflectivity and reliability meet the requirements. Similarly, those skilled in the art will also understand that the liquid storage container 101 can be designed to be insensitive to the pressing pressure, that is, regardless of the pressing pressure, the amount of solution sprayed each time is fixed, which can facilitate the calculation and setting of the expected characteristics of the hydrophilic film layer to be repaired, as well as the number of spraying times and the amount of spraying. Of course, the fixed amount of solution sprayed each time can also be adjusted as needed.

[0076] Atomizing nozzles are used to atomize the incoming solution into small droplets. Specific spray parameters can be designed to maintain a spray angle between 10° and 90°, with a single droplet volume between 0.1 ml and 0.5 ml. This allows for cost-effective, consistent, and uniform repair of the hydrophilic membrane. The hydrophilic membrane does not need to be thick and can even be very thin, as long as it achieves its intended purpose.

[0077] Regarding the specific implementation of the fixing structure 103, as shown in the figure, the fixing structure 103 is optionally configured as a claw structure, one end of which is disposed at the nozzle 102, and the other end of which is used to be engaged with the lens 1. The claw structure comprises two bow-shaped members extending symmetrically from the nozzle 102 to the lens 1, wherein the ends of the bow-shaped members each have a hook-shaped body to facilitate engagement or other fixing methods.

[0078] As can be seen from this, as has been explained in the description of this repair method, it can be understood that the treatment device 100 can be understood as an atomizing spray device, and its other function besides atomizing spraying is to check whether the film layer has failed and whether it is effective after maintenance. When checking the function, the difference from the atomizing spraying step is that the spraying solution is replaced with ordinary clean water. For example, after spraying 5 to 10 times in a row, the atomizing spray device can be removed and the surface can be checked for water droplets. If there are water droplets, it means that the film layer has failed or the film layer is ineffective after maintenance; if the water film has been evenly spread, it means that the entire film layer construction has been successfully completed.

[0079] In addition, the processing device 100 can also have a buffer structure 104, and the buffer structure 104 is arranged at one end of the fixed structure 103 for fixing the lens 1. Therefore, in actual application, the buffer structure 104 is located between the fixed part of the fixed structure 103 and the fixed part of the lens 1, so as to play the expected function, that is, to protect the appearance of the camera from being scratched or the like. Specifically, the buffer structure 104 is designed as a buffer pad, which abuts against the vertical section at the end of the fixed structure 103 and completely covers the vertical section, so as to comprehensively and economically achieve the expected function. According to the different structures of the lens 1 to be targeted, those skilled in the art can flexibly adjust the number, shape, size, layout position and other features of each part of the processing device 100, including the addition and subtraction of parts and the introduction of other parts.

[0080] In summary, it has been verified that the hydrophilic film coated on the outer surface of cameras currently used outdoors, such as in vehicle-mounted ADAS (Advanced Driver Assistance Systems), drones, sports cameras, etc., produces imaging effects far better than those without hydrophilic film coating, for example on rainy days. However, it has not yet been widely used, and the main reason is that the hydrophilic film has certain durability issues. The present invention aims to repair the originally failed hydrophilic film layer through a series of construction processes when there are problems with the durability of the hydrophilic film. Under this construction process, the thickness and reflectivity of the film layer can meet certain requirements and can achieve certain reliability requirements. Through such an implementation process, the effect of the hydrophilic film layer on the camera can be maintained to meet the needs of different visual groups or machines. The present invention uses a full-process maintenance coating process to repair the originally failed film layer, and finally restores the effect before the film layer failed.

[0081] It should be understood that all the above preferred embodiments are illustrative rather than restrictive, and various modifications or variations made by those skilled in the art to the specific embodiments described above under the concept of the present invention should be within the legal protection scope of the present invention.
