Description

Technical Field

[0001] This utility model relates to the field of optical lens inspection technology, and in particular to an optical lens inspection device with an adjustable light source assembly. Background Technology

[0002] Optical lens inspection is an important branch of optical inspection, which mainly tests and evaluates the optical performance, surface quality, and assembly accuracy of lenses. It is widely used in the production and quality inspection of cameras, mobile phone cameras, security monitoring, medical endoscopes and other fields.

[0003] For example, Chinese patent CN217543492U3 discloses a lens mounting device, a lens, and a reflectivity detection device. The lens mounting device includes a mounting frame with a lens mount inside. The lens mount has a first adjusting bracket for fixing a specular reflective lens and a second adjusting bracket for fixing a light-emitting lens, both rotatably mounted on the lens mount. The mounting frame has positioning holes. In this invention, since one end of the light-emitting lens requires an external optical fiber, the positioning holes allow for initial positioning of the lens during installation by passing the optical fiber through them. The other two positioning holes allow for the connection of optical fibers to one side of the specular reflective and diffuse reflective lenses, enabling initial positioning of these lenses. Because the adjusting brackets are rotatably mounted on the lens mount, the three optical fibers facilitate rapid adjustment of the lens angle during optical debugging, thereby improving assembly efficiency.

[0004] The aforementioned patent has the following problems: This patent has several drawbacks in its use, such as: it lacks the ability to quickly adjust the light source, diffuse reflection lens, and specular reflection lens in relation to the lens under test; secondly, because the lens surface is not perfectly symmetrical, light projected onto the lens from different angles will reflect differently, and the aforementioned patent does not have the function of adjusting the horizontal angle, resulting in low reliability of the test results. Therefore, we propose an optical lens testing device with an adjustable light source assembly. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides an optical lens testing device with an adjustable light source assembly. This solves the problems of not having the function of quickly adjusting the light source, diffuse reflection lens, specular reflection lens, and the lens under test. Furthermore, since the surface of the lens is not perfectly symmetrical, different results will be reflected when light is projected onto the lens from different angles. The aforementioned patent does not have the function of adjusting the horizontal angle, resulting in low reliability of the test results.

[0006] To achieve the above objectives, this utility model provides the following technical solution: An optical lens inspection device for an adjustable light source assembly includes an outer frame, an inner frame rotatably mounted on the inner side wall of the outer frame, four equally spaced sliders slidably mounted on the four inner walls of the outer frame and the inner frame, and multiple equally spaced scale grooves are opened on the outer side walls of the sliding grooves of the outer frame and the inner frame. Multiple locking blocks are slidably mounted on the side walls of multiple sliders. A second spring is fixedly mounted on one side of each locking block, and the other end of each second spring is fixedly connected to the slider. A mounting base is fixedly mounted on the bottom of the outer frame, and a lens is also included. A drive assembly, which is mounted in the mounting base and is used to drive the inner frame to rotate; A clamping assembly, which is mounted on the outer frame and is used to clamp the lens.

[0007] Preferably, the driving component includes: A servo motor is fixedly mounted on the top inner wall of the mounting base. A connecting post is fixedly mounted on the output end of the servo motor. The connecting post passes through the mounting base and the outer frame and is fixedly connected to the inner frame.

[0008] Preferably, the clamping assembly includes: Two mounting frames are symmetrically fixedly mounted on the inner sidewall of the outer frame. A connecting rod is slidably mounted through one end of each mounting frame and through the other end of each connecting rod. A V-groove clamping block is fixedly mounted at one end of each connecting rod. A limit block is fixedly mounted on the middle outer wall of each connecting rod. A first spring is fixedly mounted on the opposite side of each limit block.

[0009] Preferably, the two first springs are respectively sleeved on the outer walls of the two connecting rods, and the other ends of the two first springs are respectively fixedly connected to the two mounting frames.

[0010] Preferably, a V-shaped groove is provided on one side of each of the two V-groove clamping blocks, and the lens is clamped between the grooves of the two V-groove clamping blocks. The V-groove clamping blocks are rubber blocks.

[0011] Preferably, a first light source is fixedly installed on the inner wall of each of the two sliders on the left, and a diffuse reflection lens is fixedly installed on the inner wall of each of the two sliders on the right.

[0012] Preferably, a second light source is fixedly installed on the inner wall of each of the two rear sliders, and a mirror-reflecting lens is fixedly installed on the inner wall of each of the two front sliders.

[0013] Preferably, the protruding portions on the inner side of the plurality of card blocks can be inserted into the scale groove, and the protruding portions are strip-shaped.

[0014] Compared with the prior art, the present invention has the following beneficial effects: 1. By opening annular grooves on both the outer and inner frames, and then opening evenly distributed scale grooves on both sides of the grooves, when it is necessary to perform tests at different angles, simply push the block to separate it from the scale groove, and then change the detection angle by adjusting the position of the slider, thereby enabling detection at different angles and increasing the reliability of the detection results.

[0015] Second, during the process of the second light source emitting light, the angle between the inner frame and the outer frame can be changed by activating the servo motor and then driving the connecting column. This changes the horizontal direction of the second light source illuminating the lens, thereby obtaining detection results at various horizontal angles and making the detection results more accurate.

Detailed Implementation

[0019] This application provides an optical lens testing device with an adjustable light source assembly, which effectively solves the problems of lacking the ability to quickly adjust the light source, diffuse reflection lens, specular reflection lens, and the lens under test. Furthermore, since the surface of the lens is not completely symmetrical, different results will be reflected when light is projected onto the lens from different angles, and the device does not have the function of adjusting the horizontal angle, resulting in low reliability of the test results.

[0020] Example: Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, the technical solution in this application effectively solves the problems of lacking the ability to quickly adjust the light source, diffuse reflection lens, specular reflection lens, and the lens under test; secondly, because the surface of the lens is not perfectly symmetrical, different results will be reflected when light is projected onto the lens from different angles, and the lack of a function to adjust the horizontal angle results in low reliability of the test results. The overall idea is as follows: To address the problems existing in the prior art, this utility model provides an optical lens detection device for an adjustable light source assembly, including an outer frame 1, an inner frame 4 rotatably mounted on the inner side wall of the outer frame 1, four equally spaced sliders 14 slidably mounted on the four inner walls of the outer frame 1 and the inner frame 4, and multiple equally spaced scale grooves 19 are opened on the outer side walls of the sliding grooves of the outer frame 1 and the inner frame 4. Multiple locking blocks 16 are slidably mounted on the side walls of multiple sliders 14. A second spring 15 is fixedly mounted on one side of each locking block 16. The other end of each second spring 15 is fixedly connected to the slider 14. A mounting base 7 is fixedly mounted on the bottom of the outer frame 1. The frame also includes a lens 17. A drive assembly is installed in the mounting base 7 and is used to drive the inner frame 4 to rotate. A clamping assembly is mounted on the outer frame 1 and is used to clamp the lens 17.

[0021] Furthermore, the clamping components include: Two mounting frames 10 are symmetrically fixedly mounted on the inner side wall of the outer frame 1. A connecting rod 11 is slidably mounted through one end of each mounting frame 10. The other end of each connecting rod 11 is slid through the outer frame 1. A V-groove clamping block 8 is fixedly mounted on one end of each connecting rod 11. A limiting block 13 is fixedly mounted on the middle outer wall of each connecting rod 11. A first spring 12 is fixedly mounted on the opposite side of each limiting block 13.

[0022] Furthermore, two first springs 12 are respectively sleeved on the outer walls of the two connecting rods 11, and the other ends of the two first springs 12 are respectively fixedly connected to the two mounting frames 10.

[0023] Furthermore, V-shaped grooves are provided on the opposite sides of the two V-groove clamping blocks 8, and the lens 17 is clamped between the grooves of the two V-groove clamping blocks 8.

[0024] Furthermore, the inner walls of the two left sliders 14 are each fixedly equipped with a first light source 2, and the inner walls of the two right sliders 14 are each fixedly equipped with a diffuse reflection lens 3. One end of the first light source 2 and the diffuse reflection lens 3 are both aligned with the lens 17.

[0025] Furthermore, a second light source 5 is fixedly installed on the inner wall of each of the two rear sliders 14, and a mirror reflection lens 6 is fixedly installed on the inner wall of each of the two front sliders 14. One end of the second light source 5 and the mirror reflection lens 6 are aligned with the lens 17.

[0026] Furthermore, the protruding portions on the inner side of the multiple card blocks 16 can be inserted into the scale slots 19.

[0027] in: Outer frame 1: is a circular metal frame, which is fixedly installed on the mounting base 7 by bolts; First light source 2: is an LEDIN lens, the central axis of which coincides with the diameter line of the outer frame 1, so as to emit light sources to the lens 17 from various angles; Diffuse lens 3: The central axis of the lens coincides with the diameter line of the outer frame 1, so as to receive the light emitted by the first light source 2 reflected by the lens 17. Inner frame 4: It is a circular metal frame with an outer arc surface to ensure that there is no physical interference when the inner frame 4 and the outer frame 1 rotate relative to each other. The top of the outer frame 1 and the inner frame 4 are connected by a metal shaft to facilitate the relative rotation of the outer frame 1 and the inner frame 4. Second light source 5: is an LEDIN lens, the central axis of which coincides with the diameter line of the outer frame 1, so as to emit light sources to the lens 17 from various angles; Specular lens 6: The central axis of the lens coincides with the diameter line of the outer frame 1, so as to receive the light emitted by the second light source 5 reflected by the lens 17. Mounting base 7: It is a convex frustum with a mounting groove at the bottom to facilitate the installation of servo motor 9; V-groove clamping block 8: It is a rubber block. The opposite side of the two V-groove clamping blocks 8 is a V-shaped opening. A V-shaped groove is opened at the V-shaped opening to make it easier to hold the lens 17 that does not meet the specifications. Servo 9: A standard servo with a rotation range of 1° to 180°; Mounting frame 10: It is a rectangular metal frame with a hollow inner side to facilitate the installation of the limiting block 13. It has round holes at both ends with the same specifications as the outer diameter of the connecting rod 11. Connecting rod 11: It is a metal rod, one end of which is glued to the V-groove clamp 8, and the other end is threaded with a nut. By pulling the connecting rod 11, the distance between the two V-groove clamps 8 can be adjusted. First spring 12: It is a silicon manganese spring steel spring, with both ends abutting against the limiting block 13 and the mounting frame 10. The initial state is a semi-compressed state, so as to provide pressure for clamping the lens 17. Limiting block 13: It is a rectangular plastic block with a through hole in the middle. It is fixed to the outer wall of the connecting rod 11 by bolts so as to provide support for the first spring 12. Slider 14: It is a hollow metal block with a groove on one side surface to facilitate the installation of the clip 16. The hollow part is used to install the first light source 2, the diffuse reflection lens 3, the second light source 5 or the specular reflection lens 6. The second spring 15 is a resistance spring. One end is fixed to the locking block 16 by welding, and the other end is fixed to the slider 14 by welding the fixing plate. Card block 16: It is U-shaped, and a strip protrusion is fixedly installed on the inner wall. The specifications of the strip protrusion are the same as those of the scale groove 19. Lens 17: The lens of the light source component to be tested; Connecting column 18: It is a cylindrical metal column with a vertical keyway at the point where it mates with the inner frame 4 and is limited by a key. Scale groove 19: It is a rectangular groove in the shape of a bar, with a rounded corner at one end near the edge to facilitate the insertion of the protrusion in the card block 16.

[0028] Working principle: First, start the servo motor 9, which drives the inner frame 4 to rotate via the connecting column 18, increasing the gap between the outer frames 1 and 1, making it easier to install the lens 17 onto the clamping assembly. Then, push the two V-groove clamps 8 to separate or pull the connecting rod 11. During this process, the V-groove clamps 8 will drive the connecting rod 11 to move, and the first spring 12 will be compressed under the action of the limiting block 13. Next, align the lens 17 with the groove between the two, and then release the V-groove clamps 8, so that the V-groove clamps 8 will move closer to the lens 17 under the action of the first spring 12 in the compressed state, and lock the lens 17 in place.

[0029] The second step involves pushing the locking block 16 on any slider 14 away from the lens 17, causing the protrusion on the inner side of the locking block 16 to disengage from the scale groove 19. Simultaneously, the second spring 15 is compressed, allowing the slider 14 to move along the arc-shaped groove on the inner frame 4 or outer frame 1. After the angle adjustment is complete, the locking block 16 is released, allowing it to re-insert into the scale groove 19 under the action of the second spring 15, thus restricting the movement of the slider 14. By adjusting the positions of each slider 14, the angles between the first light source 2, the diffuse reflection lens 3, the second light source 5, and the specular reflection lens 6 and the lens 17 can be adjusted. The first light source 2 emits light, which is then received by the diffuse reflection lens 3, and the second light source 5 emits light, which is then received by the specular reflection lens 6. The order in which the first light source 2 and the second light source 5 emit light must be sequential to avoid mutual interference.

[0030] Third, during the process of the second light source 5 emitting light, the servo motor 9 can be activated, and then the angle between the inner frame 4 and the outer frame 1 can be changed through the transmission of the connecting column 18. Then the horizontal direction of the second light source 5 illuminating the lens 17 changes, thereby obtaining the detection results of various horizontal angles.

[0031] Finally, it should be noted that the above embodiments are merely examples for clearly illustrating the present invention and are not intended to limit the implementation. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations. However, obvious variations or modifications derived therefrom are still within the protection scope of this invention.
