Description

Technical Field

[0001] This utility model belongs to the technical field of lens testing equipment, specifically relating to an automatic glare testing machine for camera lenses. Background Technology

[0002] With societal development, cameras are being used more and more widely, and people are demanding increasingly higher-definition images. To ensure clearer images, camera modules require structural testing to verify their compliance with usage requirements. The lens is a crucial component of a camera, and testing it is an essential part of camera module testing. Structural defects in the lens can be detected through glare, but current production equipment is inefficient at testing glare in camera lenses. Utility Model Content

[0003] To solve the above-mentioned technical problems, this utility model provides an automatic camera lens glare testing machine. By setting a first rotating stage and a second rotating stage in the frame, and then controlling the up and down movement of the folded light path emitted from the light source, it can meet the different testing angles and distances of the product, and the data collection is more accurate and the test results are more precise.

[0004] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0005] An automatic glare testing machine for camera lenses includes a frame, a light source assembly, and a testing assembly. The mounting platform on the upper surface of the frame has a C-shaped structure. The light source assembly includes a light source and a reflective component. The light source is located in the middle of the mounting platform and points downward toward the reflective component located at the bottom of the frame. The testing assembly includes a first rotating platform, a second rotating platform, a lens suction gripper, and a sensor. The first rotating platform is rotatably connected to the mounting platform, the second rotating platform is rotatably connected to the first rotating platform, the lens suction gripper is movably connected to the second rotating platform, and the sensor is located at the bottom of the second rotating platform. Light emitted from the light source passes through the reflective component and enters the sensor from bottom to top. During the driving process, the lens suction gripper enters / exits between the reflective component and the sensor.

[0006] The left and right ends of the first rotating stage are rotatably connected to the mounting platform and rotate around the x-axis. The second rotating stage is rotatably connected to the center of the first rotating stage, and the rotation axis of the second rotating stage is perpendicular to the first rotating stage. An x-axis mover and a y-axis mover are sequentially provided between the lens suction gripper and the second rotating stage. The lens suction gripper moves in the x-axis and y-axis directions under the drive of the x-axis mover and the y-axis mover. A z-axis mover is provided between the sensor and the second rotating stage. The sensor moves in the z-axis direction under the drive of the z-axis mover.

[0007] The reflective component includes an incoming light reflector and an outgoing light reflector. Light from the light source passes through the incoming light reflector and the outgoing light reflector in sequence and then enters the sensor upwards. The reflective component also includes a support platform, a moving platform, a five-way adjuster, a three-way adjuster, and a Z-axis adjuster. The incoming light reflector is mounted on the support platform, the outgoing light reflector is connected to the support platform via the three-way adjuster, the support platform is connected to the moving platform via the five-way adjuster, and the moving platform is connected to the frame via the Z-axis adjuster.

[0008] This automatic camera lens glare testing machine employs a vertical placement design with downward testing. The light source emits downwards from the mounting platform, is adjusted on the reflective component, and then shines upwards into the sensor. The sensor and lens are separately fixed on a second rotating platform. A quick-change fixture, a lens suction gripper, is used for vacuum adsorption of the lens, allowing for rapid lens replacement. It can be integrated with automatic loading and unloading equipment to achieve fully automated production, further improving production efficiency and enhancing enterprise competitiveness. For convenient loading, an X-axis mover and a Y-axis mover are sequentially installed between the lens suction gripper and the second rotating platform, enabling two-way movement on the horizontal plane. The lens suction gripper extends from the testing position between the reflective component and the sensor via motion control, facilitating operator loading and unloading while simultaneously meeting automatic loading and unloading requirements and improving efficiency.

[0009] To achieve different testing angles and distances for the product, a first and second rotary table are set up to adjust the rotation angles of the sensor and lens gripper on the x and z axes. A z-axis mover between the sensor and the second rotary table is used to adjust the distance movement of the sensor in the z-axis direction. On the reflective component, the light from the light source first enters the light-incoming reflector, then the light-outcoming reflector, and finally enters the sensor. A three-way adjuster is set between the light-outcoming reflector and the support platform to achieve translational distances Tx, Ty, and Tz in the x, y, and z axes. A five-way adjuster is set between the support platform and the moving platform to achieve translational distances Tx, Ty, and Tz in the x, y, and z axes, as well as axial rotation in the x and y axes. The moving platform is connected to the frame via a z-axis adjuster to adjust the distance movement of the moving platform in the z-axis direction. Therefore, after the lens is moved to the pre-alignment position with the sensor, automatic optical alignment is performed to align the center of the lens with the center of the sensor. The z-axis mover and z-axis adjuster are controlled to focus the light spot. Rotating the first and second rotary stages allows for imaging and image capture of the light spot at different angles.

[0010] Furthermore, the light source assembly also includes a four-way adjuster and a bracket, the light source being connected to the bracket via the four-way adjuster, and the bracket being detachably connected to the mounting platform.

[0011] Compared with the prior art, the advantages of this utility model are as follows: the dual-rotation structure of the first and second rotary tables, as well as the three-way and five-way adjusters, enable the variability of the angle of light entering the lens. When the dual-rotation structure is in the loading and unloading posture, the lens suction claw is controlled to move and extend out of the test position, which is convenient for the operator to pick up and put down materials, while meeting the requirements of automatic loading and unloading and improving efficiency. This testing machine does not directly move the light source to adjust its distance from the lens. Instead, the distance between the two can be adjusted in a smaller space through the z-axis mover and z-axis adjuster that can move in the vertical direction. When combined with a robotic arm, it can also achieve full automation, reduce manual operation, and make data collection more accurate and test results more precise. Attached Figure Description

[0024] The specific embodiments of this utility model will now be described with reference to the accompanying drawings:

[0025] like Figure 1-9 As shown, an automatic glare testing machine for camera lenses includes a frame 1, a light source assembly 2, and a testing assembly 3. The mounting platform 11 on the upper surface of the frame 1 has a C-shaped structure. The light source assembly 2 includes a light source 21 and a reflective component 22. The light source 21 is located in the middle of the mounting platform 11 and points downward toward the reflective component 22 located at the bottom of the frame 1. The testing assembly 3 includes a first rotating platform 31, a second rotating platform 32, a lens suction claw 33, and a sensor 34. The first rotating platform 31 is rotatably connected to the mounting platform 11, the second rotating platform 32 is rotatably connected to the first rotating platform 31, the lens suction claw 33 is movably connected to the second rotating platform 32, and the sensor 34 is located at the bottom of the second rotating platform 32. The light emitted from the light source 21 passes through the reflective component 22 and enters the sensor 34 from bottom to top. The lens suction claw 33 enters / exits between the reflective component 22 and the sensor 34 during the driving process.

[0026] The left and right ends of the first rotating platform 31 are rotatably connected to the mounting platform 11 and rotate around the x-axis. The second rotating platform 32 is rotatably connected to the center of the first rotating platform 31, and the rotation axis of the second rotating platform 32 is perpendicular to the first rotating platform 31. An x-axis mover 35 and a y-axis mover 36 are sequentially provided between the lens suction claw 33 and the second rotating platform 32. The lens suction claw 33 moves in the x-axis and y-axis directions under the drive of the x-axis mover 35 and the y-axis mover 36. A z-axis mover 37 is provided between the sensor 34 and the second rotating platform 32. The sensor 34 moves in the z-axis direction under the drive of the z-axis mover 37.

[0027] The reflective component 22 includes an input reflector 221 and an output reflector 222. Light from the light source 21 passes through the input reflector 221 and the output reflector 222 in sequence and then enters the sensor 34 upwards. The reflective component 22 also includes a support platform 223, a moving platform 224, a five-way adjuster 225, a three-way adjuster 226, and a z-axis adjuster 227. The input reflector 221 is mounted on the support platform 223. The output reflector 222 is connected to the support platform 223 via the three-way adjuster 226. The support platform 223 is connected to the moving platform 224 via the five-way adjuster 225. The moving platform 224 is connected to the frame 1 via the z-axis adjuster 227.

[0028] Furthermore, the light source assembly 2 also includes a four-way adjuster 23 and a bracket 24. The light source 21 is connected to the bracket 24 via the four-way adjuster 23, and the bracket 24 is detachably connected to the mounting platform 11.

[0029] Description of the working principle of this utility model:

[0030] The automatic glare testing machine for camera lenses using this structure employs a vertical placement and downward testing design. Specifically, the light source 21 emits light downwards from the mounting platform 11, which is then adjusted on the reflector 22 before being directed upwards into the sensor 34. The sensor 34 and lens are separately fixed on the second rotating platform 32. A quick-change fixture, the lens suction claw 33, is used for vacuum adsorption of the lens, allowing for rapid lens replacement. It can be integrated with automatic loading and unloading equipment according to customer needs, achieving fully automated production and further improving production efficiency and enterprise competitiveness. For convenient loading, an x-axis mover 35 and a y-axis mover 36 are sequentially installed between the lens suction claw 33 and the second rotating platform 32, enabling two-way movement on the horizontal plane. The lens suction claw 33 extends from the testing position between the reflector 22 and the sensor 34 via motion control, facilitating operator loading and unloading while simultaneously meeting automatic loading and unloading requirements and improving efficiency.

[0031] To achieve different testing angles and distances for the product, a first rotating stage 31 and a second rotating stage 32 are provided to adjust the rotation angles of the sensor 34 and lens gripper 33 along the x and z axes. A z-axis mover 37 between the sensor 34 and the second rotating stage 32 is used to adjust the distance movement of the sensor 34 in the z-axis direction. On the reflective component 22, the light from the light source 21 first enters the light-incoming reflector 221, then the light-outgoing reflector 222, and finally enters the sensor 34. Therefore, a three-way adjuster 226 is provided between the light-outgoing reflector 222 and the support stage 223. The system achieves translational distances Tx, Ty, and Tz in the x, y, and z axes. A five-axis adjuster 225 is installed between the support stage 223 and the moving stage 224, enabling translational distances Tx, Ty, and Tz in the x, y, and z axes, as well as axial rotation along the x and y axes. The moving stage 224 is connected to the frame 1 via a z-axis adjuster 227, used to adjust the distance movement of the moving stage 224 in the z-axis direction. Therefore, after the lens is moved to the pre-alignment position with the sensor 34, automatic optical alignment is performed, aligning the center of the lens with the center of the sensor 34. The z-axis mover 37 and the z-axis adjuster 227 are controlled to achieve focusing of the light spot. Rotating the first rotating stage 31 and the second rotating stage 32 enables imaging and image acquisition of light spots at different angles. Since how the sensor 34 samples is existing technology, it will not be described in detail here.

[0032] In order to further adjust the emission angle of the light source 21, a four-way adjuster 23 is set between the light source 21 and the bracket 24, which realizes the translation distance Tx and Ty in the x-axis and y-axis directions, as well as the axial rotation in the x-axis and y-axis.

[0033] The beneficial effects of this utility model are as follows: the dual-rotation structure of the first rotary table 31 and the second rotary table 32, and the three-way adjuster 226, five-way adjuster 225, and four-way adjuster 23 enable the variability of the angle of light entering the lens. When the dual-rotation structure is in the loading and unloading posture, the lens suction claw 33 is controlled to move and extend out of the test position, which is convenient for the operator to pick up and put down the material, while meeting the requirements of automatic loading and unloading and improving efficiency. This testing machine does not directly move the light source 21 to adjust its distance from the lens. Through the z-axis mover 37 and z-axis adjuster 227 that can move in the vertical direction, the distance between the two can be adjusted in a smaller space. When combined with a robotic arm, it can also meet the requirements of full automation, reduce manual operation, and make data collection more accurate and test results more accurate.

[0034] The above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this utility model.
