Description

Technical Field

[0001] This invention relates to the field of lens inspection technology, and more particularly to a lens inspection device. Background Technology

[0002] The lens of a camera is the core optical component responsible for focusing light and forming a clear image. It is a sophisticated multi-component optical system. Cameras are often exposed to harsh environments and may come into contact with various corrosive substances. If the lens of a camera is corroded, its optical performance will degrade, resulting in a decrease in image quality. Therefore, corrosion resistance testing is performed on the lens to ensure its quality.

[0003] In the process of corrosion resistance testing of lenses, the lens is usually clamped by a U-shaped clamp and then a corrosive liquid is sprayed onto the lens for corrosion resistance testing. However, the contact point between the U-shaped clamp and the lens is difficult to reach the corrosive liquid, making it impossible to simulate the corrosion situation in a real environment. It is difficult to judge the overall durability of the lens under a real uniform corrosive environment (such as acid rain or salt spray), and the test results cannot reflect the true reliability of the lens. Summary of the Invention

[0004] In view of this, the present invention provides a lens testing device that can overcome the shortcomings of U-shaped clamps and lens contact points, which make it difficult to contact corrosive liquids, simulate corrosion conditions in real environments, determine the overall durability of the lens in a real uniform corrosion environment, and make the test results unable to reflect the true reliability of the lens.

[0005] The technical implementation scheme of the present invention is as follows: a lens inspection device includes a base plate, a housing, an electric guide rail, a frame, a liquid inlet pipe, an electric nozzle, a first spur gear, a moving rod, a moving plate, a support plate, a lead screw, a flipping mechanism, and an imaging mechanism. The housing is connected to the top of the base plate, and an electric guide rail is installed inside the housing. The bottom of the slider of the electric guide rail is connected to a frame for storing corrosive liquid. The frame is connected to a liquid inlet pipe for adding corrosive liquid. Electric nozzles are evenly spaced at the bottom of the frame. The first spur gear is rotatably connected to both the left and right sides of the housing. Two moving rods are slidably connected to the first spur gear. A moving plate is connected to each moving rod. A support plate for holding the lens is connected to each moving plate. A lead screw is rotatably connected to each moving plate. The lead screw and the first spur gear are connected by a thread. The flipping mechanism is used to flip the lens, and the imaging mechanism is used to image the lens.

[0006] In a preferred embodiment of the present invention, the flipping mechanism includes a servo motor, a second spur gear, an internal gear ring, and a third spur gear. Servo motors are installed on both the left and right sides of the housing. The output shafts of the servo motors are connected to the second spur gears, which mesh with the first spur gear. Internal gear rings are connected to both the left and right sides of the housing. A third spur gear is connected to the lead screw, which meshes with the internal gear ring.

[0007] In a preferred embodiment of the present invention, the shooting mechanism includes a mounting block and a vision camera. The mounting block is connected to the frame, and the vision camera for shooting the lens is mounted at the bottom of the mounting block.

[0008] In a preferred embodiment of the present invention, a protective cover and a transparent block are also included. The bottom of the mounting block is connected to a protective cover for protecting the vision camera. The vision camera is located inside the protective cover, and the bottom of the protective cover is connected to the transparent block.

[0009] In a preferred embodiment of the invention, a collection tank is also included, with the collection tank for collecting corrosive liquids placed on top of the base plate.

[0010] In a preferred embodiment of the present invention, a limiting plate is also included, and a limiting plate for limiting the position of the collection box is connected to the top of the bottom plate.

[0011] In a preferred embodiment of the present invention, a protective plate is also included, with protective plates snapped onto both the front and rear sides of the box.

[0012] In a preferred embodiment of the present invention, the protective plate is made of a transparent material.

[0013] Compared with the prior art, the present invention has the following advantages:

[0014] 1. This invention uses an electric nozzle to spray corrosive liquid onto a lens, and a vision camera to photograph the lens. The image captured by the vision camera can be used to determine the corrosion resistance of the lens. A tray holds the lens, allowing the corrosive liquid to come into contact with every area of ​​the lens, simulating corrosion conditions in a real environment. This allows for the assessment of the overall durability of the lens under a real, uniform corrosion environment, and the test results can reflect the true reliability of the lens.

[0015] 2. The output shaft of the servo motor can drive the tray to rotate, which in turn drives the lens to rotate, flipping the lens over and performing corrosion resistance testing on both sides of the lens. This allows for a more comprehensive corrosion resistance test and improves the accuracy of the test results.

[0016] 3. The vision camera can be protected by a protective cover and a transparent block to prevent corrosive liquids from splashing onto it. Attached Figure Description

The technical solutions of the present invention will now be clearly and completely described in conjunction with the accompanying drawings. It should be understood that the technical features involved in the different embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0029] refer to Figures 1-7 A lens inspection device includes a base plate 1, a housing 2, an electric guide rail 3, a frame 4, an inlet pipe 5, an electric nozzle 6, a first spur gear 7, a moving rod 8, a moving plate 9, a support plate 10, a lead screw 11, a flipping mechanism, and a shooting mechanism. The housing 2 is bolted to the top of the base plate 1. The front and rear sides of the housing 2 are open. The electric guide rail 3 is bolted to the top center of the housing 2. The bottom of the slider of the electric guide rail 3 is bolted to the frame 4. The inlet pipe 5 is connected to the upper rear side of the frame 4. The electric nozzles 6 are evenly spaced at the bottom of the frame 4. The first spur gear is rotatably connected to the left and right sides of the lower part of the housing 2. Two movable rods 8 are slidably connected to the middle of the wheel 7 and the first spur gear 7. The two movable rods 8 on the same first spur gear 7 are arranged vertically opposite each other. The movable rods 8 on the left and right sides are connected to movable plates 9 at their close ends. The movable plates 9 on the left and right sides are connected to support plates 10 at their close ends. The support plates 10 are arc-shaped to adapt to the contour of the lens, so as to better support the lens. The movable plates 9 on the left and right sides are rotatably connected to lead screws 11 at their far ends. The lead screws 11 and the first spur gear 7 are connected by threads. The flipping mechanism is used to flip the lens, and the shooting mechanism is used to shoot the lens.

[0030] refer to Figure 6 and Figure 7 The flipping mechanism includes a servo motor 121, a second spur gear 122, an internal gear ring 123, and a third spur gear 124. The servo motor 121 is bolted to both the left and right sides of the lower part of the housing 2. The output shaft of the servo motor 121 is connected to the second spur gear 122 by a key. The second spur gear 122 meshes with the first spur gear 7. The internal gear ring 123 is connected to both the left and right sides of the lower part of the housing 2. The ends of the lead screws 11 on the left and right sides that are far apart from each other are connected to the third spur gear 124 by a key. The third spur gear 124 meshes with the internal gear ring 123.

[0031] refer to Figure 3 The shooting mechanism includes a mounting block 131 and a vision camera 132. The mounting block 131 is connected to the lower front side of the frame 4 by bolts, and the vision camera 132 is mounted on the bottom of the mounting block 131 by bolts.

[0032] The operator places the lens on the two lower support plates 10, which hold the lens in place. Corrosive liquid is then injected into the frame 4 through the inlet pipe 5. The electric nozzle 6 sprays the corrosive liquid onto the lens. Subsequently, the electric guide rail 3 moves the frame 4 backward, which in turn moves the mounting block 131 backward. The mounting block 131 then moves the vision camera 132 backward, positioning it directly above the lens. The vision camera 132 then takes a picture of the lens. The vision camera 132 can be connected to an external computer, and the captured images can be displayed on the computer for analysis. To improve the corrosion resistance of the broken lens, when the lens needs to be flipped, the operator controls the output shaft of the servo motor 121 to rotate, which drives the second spur gear 122 to rotate. The second spur gear 122 drives the first spur gear 7 to rotate, which in turn drives the moving rod 8 and the lead screw 11 to rotate. The moving rod 8 drives the moving plate 9 to rotate, which in turn drives the support plate 10 to rotate. The support plate 10 then drives the lens to rotate, thus flipping the lens. The lead screw 11 can drive the third spur gear 124 to rotate. The third spur gear 124 rolls on the internal gear ring 123, so it will rotate on its own axis. The lead screw 11 will also rotate on its own axis and move simultaneously. The two lead screws 11 below... As the upper two lead screws 11 move away from each other, the lower two support plates 10 also move away from each other, gradually disengaging from the lens. Simultaneously, the upper two support plates 10 move closer together, gradually contacting the lens. While the lead screws 11 move, the third spur gear 124 also moves. Because the internal gear ring 123 is relatively wide, the third spur gear 124 can maintain engagement with the internal gear ring 123, ensuring smooth lens flipping. After the lens flipping is complete, the upper two support plates 10 hold the lens, and the lower two support plates 10... After detaching from the lens, the operator shuts off the servo motor 121 and then controls the electric guide rail 3 to move the frame 4 forward. The frame 4 then moves the electric nozzle 6 forward, positioning it directly above the lens. The electric nozzle 6 then sprays corrosive liquid onto the other side of the lens, performing corrosion resistance testing on both sides. This allows for a more comprehensive corrosion resistance test, improving the accuracy of the test results. The support plate 10 holds the lens, ensuring that the corrosive liquid can reach every area of ​​the lens, simulating corrosion conditions in a real environment. This allows for the assessment of the lens's overall durability under a real, uniform corrosion environment, and the test results reflect the lens's true reliability.

[0033] refer to Figure 8It also includes a protective cover 141 and a transparent block 142. The protective cover 141 is bolted to the bottom of the mounting block 131. The vision camera 132 is located inside the protective cover 141. The transparent block 142 is connected to the bottom of the protective cover 141. The vision camera 132 can take pictures of the lens through the transparent block 142. The protective cover 141 and the transparent block 142 can protect the vision camera 132 and prevent corrosive liquids from splashing onto the vision camera 132.

[0034] refer to Figure 9 It also includes a collection box 15, which is placed on top of the base plate 1. The electric nozzle 6 sprays corrosive liquid onto the lens, and excess corrosive liquid falls into the collection box 15 to collect the corrosive liquid for recycling and saving resources.

[0035] refer to Figure 9 It also includes a limiting plate 16. The top left and right sides of the base plate 1 are connected to the limiting plate 16 by bolts. The collection box 15 is located between the two limiting plates 16. The limiting plate 16 can limit the collection box 15 to prevent the position of the collection box 15 from shifting.

[0036] refer to Figure 1 It also includes a protective plate 17. The protective plate 17 is snapped onto both the front and rear sides of the box 2. The protective plate 17 can seal the front and rear sides of the box 2 to prevent corrosive liquids from splashing out. The protective plate 17 is made of transparent material so as to observe the testing status of the lens.

[0037] All components of this device are made of corrosion-resistant materials, which have higher corrosion resistance and can extend the service life of the device.

[0038] Obviously, the embodiments described above are only some embodiments of the present invention, and not all embodiments. They only express the preferred implementation of the present invention and are described in a relatively specific and detailed manner, but should not be construed as limiting the scope of the present invention.
