Furthermore, the stable testing environment provided by the testing chamber, combined with the collaborative work of multiple testing mechanisms, further improves testing efficiency and reduces equipment maintenance costs.

[0016] The working principle of the lens testing device is as follows: The test chamber provides a closed environment that effectively isolates external light and temperature fluctuations, thereby ensuring the stability of the test conditions. Small light testing mechanisms, large light testing mechanisms, and gray board testing mechanisms are spaced apart within the test chamber along a first direction. These three mechanisms test different performance indicators of the lens, forming an ordered test sequence. A loading and positioning mechanism is also positioned within the test chamber along the first direction. Its main function is to move the lens along the first direction to a position corresponding to any one of the small light, large light, or gray board testing mechanisms. This allows the lens to complete multiple performance indicator tests within a single device without frequent equipment changes or repeated lens loading and unloading. When a specific test is required, the loading and positioning mechanism precisely moves the lens to the corresponding test mechanism position. For example, if a small light test is required, the loading and positioning mechanism moves the lens to the position corresponding to the small light testing mechanism; if a large light or gray board test is required, positioning is achieved similarly through the movement of the loading and positioning mechanism. Therefore, the lens can complete multiple tests sequentially without disassembly, avoiding the cumbersome operation and error accumulation problems caused by multiple loading and unloading and equipment switching in traditional methods. The test chamber serves as the basic platform to house all components. The interval arrangement of the small lamp test mechanism, the large lamp test mechanism, and the gray board test mechanism forms a continuous test path, while the loading and positioning mechanism drives the lens to move along this path, realizing automated switching of test items. In this way, multiple test mechanisms and the loading and positioning mechanism work together to fundamentally solve the problems of traditional lens testing devices having single functions, cumbersome and time-consuming operation, requiring enterprises to purchase multiple test instruments, increasing maintenance costs, and the easy introduction of errors and environmental differences that affect test results during multiple loading, unloading, and movement of the lens.

[0023] This invention provides a lens testing device, with reference to... Figure 1 , Figure 2 and Figure 3 The lens testing device includes a test chamber 1, a small light testing mechanism 2, a large light testing mechanism 3, a gray board testing mechanism 4, and a loading and positioning mechanism 5. The small light testing mechanism 2, the large light testing mechanism 3, and the gray board testing mechanism 4 are arranged at intervals along a first direction in the test chamber 1. The loading and positioning mechanism 5 is arranged along the first direction in the test chamber 1 and is used to move the lens along the first direction to a position corresponding to any one of the small light testing mechanism 2, the large light testing mechanism 3, and the gray board testing mechanism 4, so that the small light testing mechanism 2, the large light testing mechanism 3, or the gray board testing mechanism 4 can test the lens.

[0024] As an example, the lens testing device is used to test lenses and specifically includes a test chamber 1, a small light testing mechanism 2, a large light testing mechanism 3, a gray board testing mechanism 4, and a loading and positioning mechanism 5. The test chamber 1 is a closed structure, its main function being to provide a stable testing environment (dark environment). The test chamber 1 can be made of sound-insulating or light-shielding materials to reduce interference from external environmental factors during the testing process. The small light testing mechanism 2, the large light testing mechanism 3, and the gray board testing mechanism 4 are used to test different performance indicators of the lens; these testing mechanisms can adopt a modular design, facilitating replacement or adjustment according to testing needs. For example, the small light testing mechanism 2 can simulate various testing scenarios by configuring light sources of different brightness, the large light testing mechanism 3 can adapt to different testing requirements by adjusting the beam angle, and the gray board testing mechanism 4 can meet diverse testing needs by replacing test boards of different gray levels. The main function of the loading and positioning mechanism 5 is to automatically position the lens during the testing process; the loading and positioning mechanism 5 can move the lens through a robotic arm, slide rail, or other forms of transmission device. For example, a pneumatic slide is used as the driving component, and a high-precision sensor is used to detect position information, thereby accurately moving the lens to the position corresponding to the target testing mechanism.

[0025] This example lens testing apparatus, by integrating multiple testing mechanisms and an automated loading and positioning mechanism 5, achieves the goal of completing comprehensive performance testing of lenses within a single device. Compared to traditional methods that require frequent equipment changes and multiple lens loading and unloading operations, this technical solution significantly reduces operational steps and avoids testing errors caused by environmental differences. Furthermore, the stable testing environment provided by the testing chamber 1, combined with the collaborative work of multiple testing mechanisms, further improves testing efficiency and reduces equipment maintenance costs.

[0026] The working principle of the lens testing device is as follows: Test chamber 1 provides a closed environment that effectively isolates external light and temperature fluctuations, thereby ensuring the stability of test conditions. Small light testing mechanism 2, large light testing mechanism 3, and gray board testing mechanism 4 are spaced apart within test chamber 1 along a first direction. These three mechanisms test different performance indicators of the lens, forming an ordered test sequence. Loading and positioning mechanism 5 is positioned within test chamber 1 along the first direction. Its main function is to move the lens along the first direction to a position corresponding to any one of the small light testing mechanism 2, large light testing mechanism 3, or gray board testing mechanism 4. This allows the lens to complete multiple performance indicator tests within a single device without frequent equipment changes or repeated lens loading and unloading. When a specific test is required, loading and positioning mechanism 5 precisely moves the lens to the corresponding test mechanism position. For example, if a small light test is required, loading and positioning mechanism 5 moves the lens to the position corresponding to small light testing mechanism 2; if a large light test or gray board test is required, positioning is achieved similarly through the movement of loading and positioning mechanism 5. Therefore, the lens can complete multiple tests sequentially without disassembly, avoiding the cumbersome operation and error accumulation problems caused by multiple loading and unloading and equipment switching in traditional methods. Test chamber 1 serves as the basic platform to accommodate all components. The interval setting of small lamp test mechanism 2, large lamp test mechanism 3, and gray board test mechanism 4 constitutes a continuous test path, while the loading and positioning mechanism 5 drives the lens to move along this path, realizing automated switching of test items. In this way, multiple test mechanisms and loading and positioning mechanism 5 work together to fundamentally solve the problems of traditional lens testing devices having single functions, cumbersome and time-consuming operation, requiring enterprises to purchase multiple testing instruments, increasing maintenance costs, and the easy introduction of errors and environmental differences during multiple loading and unloading of the lens affecting the test results.

[0027] In one embodiment, reference is made to Figure 9 The loading and positioning mechanism 5 includes a first moving track 51, a contour positioning frame 52, and a first driving component 53. The first moving track 51 is disposed on the inner bottom wall of the test chamber 1 along a first direction. The contour positioning frame 52 is movably mounted on the first moving track 51 along the first direction and is used to support the lens. The first driving component 53 is disposed on the first moving track 51 along the first direction and is connected to the contour positioning frame 52, and is used to drive the contour positioning frame 52 to move.

[0028] As an example, the loading and positioning mechanism 5 includes a first moving track 51, a contour positioning frame 52, and a first driving component 53. The first moving track 51 is a rigid guide structure, which can be implemented using a linear guide, a groove, or a similar mechanical structure with linear constraint function. It provides a precise linear motion path for the contour positioning frame 52, preventing lens displacement due to path bending or shaking. The contour positioning frame 52 is a support device highly matched to the lens shape. It can be customized to fit lenses of different specifications, closely conforming to the lens body and suppressing the risk of shaking or falling off during movement. The first driving component 53 is a device capable of providing controllable driving force, which can be implemented using a stepper motor, servo motor, or cylinder, ensuring smooth movement and precise positional adjustment of the contour positioning frame 52. For example, the first driving component 53 includes a first motor and a first driving shaft. The first driving shaft is rotatably mounted on the first moving track 51, and the first driving shaft is provided with a driving block connected to the contour positioning frame 52, or the contour positioning frame 52 is movably mounted on the first driving shaft. The first motor is connected to the first driving shaft and drives the first driving shaft to rotate, thereby driving the contour positioning frame 52 to move.

[0029] In this example, by integrating the design of the first moving track 51, the contour positioning frame 52, and the first driving component 53, the positioning stability and movement accuracy of the lens during the testing process are significantly improved, providing a strong guarantee for the reliability of subsequent test results and effectively solving the positioning stability problem during lens movement. The first moving track 51, as a rigid guiding reference, strictly constrains the movement path of the contour positioning frame 52 to be in a straight line, thus providing a stable motion basis for the dynamic transfer of the lens. The contour positioning frame 52, through its shape highly matching the lens's outline, can maintain the lens's fixed posture during movement, reducing test errors introduced by vibration. The first driving component 53 acts directly on the contour positioning frame 52, providing a smooth and controllable driving force, enabling the lens to reliably reach the designated test point. Furthermore, this scheme, combined with the inner bottom wall of the test chamber 1, forms a complete positioning system, which not only improves the repeatability accuracy of lens movement but also significantly reduces the operational complexity and error risks associated with manual adjustments, thereby improving overall testing efficiency.

[0030] In one embodiment, reference is made to Figure 4 and Figure 5The small light testing mechanism 2 includes a first support frame 21, a first horizontal moving component 22, a first lifting component 23, and a small light testing plate 24. The first support frame 21 is installed on the inner bottom wall of the testing chamber 1, located on one side of the loading and positioning mechanism 5. The first horizontal moving component 22 is arranged on the first support frame 21 along a second direction, and the first lifting component 23 is arranged on the first horizontal moving component 22 along a third direction. The small light testing plate 24 is installed on the first lifting component 23. The first horizontal moving component 22 and the first lifting component 23 cooperate to adjust the position of the small light testing plate 24 so that the small light testing plate 24 can test the lens.

[0031] As an example, the small lamp testing mechanism 2 includes a first support frame 21, a first horizontal movement component 22, a first lifting component 23, and a small lamp testing plate 24. The first support frame 21 is a basic structural component used to fix and support the entire small lamp testing mechanism 2. It can be implemented using a metal profile frame or a cast bracket, providing a stable mounting platform for other components and ensuring the rigidity and stability of the overall structure. The first horizontal movement component 22 is a transmission device capable of moving the load along a specific direction in the horizontal plane. It can be implemented using a ball screw pair, linear motor, or synchronous belt drive, providing precise horizontal displacement control. The first lifting component 23 is a mechanical structure capable of vertical position adjustment. It can be implemented using an electric push rod, pneumatic slide, or screw jack, providing precise height adjustment. The small lamp testing plate 24 is a testing module integrating a test light source and detection elements. It can be implemented using an LED array or fiber optic lighting system to complete the testing of lens optical performance.

[0032] In this example, the first support frame 21 is installed on the inner bottom wall of the test chamber 1, located on one side of the loading and positioning mechanism 5. The stable installation of the first support frame 21 ensures that the relative positional relationship between the entire small lamp testing mechanism 2, the test chamber 1, and the loading and positioning mechanism 5 remains constant. This layout effectively avoids interference between mechanisms and optimizes the utilization efficiency of the test space. The arrangement of the first horizontal moving component 22 along the second direction forms an orthogonal relationship with the first direction of lens movement. This design is particularly suitable for compensating for lateral deviations caused by differences in lens specifications or installation errors, achieving precise position adjustment in the horizontal direction. The setting of the first lifting component 23 along the third direction provides height adjustment capability independent of horizontal movement. This orthogonal dual-axis adjustment mechanism ensures that adjustments in each direction do not interfere with each other, thereby enabling precise control of the incident angle of the test light. Through the coordinated work of the first horizontal moving component 22 and the first lifting component 23, the small lamp testing board 24 can achieve free positioning in a two-dimensional plane. This dynamic adjustment capability significantly improves the adaptability and reliability of the testing process. When the small lamp testing mechanism 2 is used in conjunction with the loading and positioning mechanism 5 in the testing chamber 1, the position of the small lamp testing plate 24 can be automatically adjusted according to the specific size of the lens and the testing requirements, eliminating the need for manual intervention and significantly shortening the test preparation time. In particular, through the dual-axis linkage adjustment mechanism, the small lamp testing plate 24 can be quickly and accurately aligned with lenses of different specifications, significantly improving testing accuracy and efficiency. In addition, this adjustable design also enhances the versatility of the testing device, enabling it to adapt to the testing requirements of various types of lenses and reducing equipment purchase and maintenance costs.

[0033] In one embodiment, reference is made to Figure 4 and Figure 5 The first horizontal moving component 22 includes a second moving track 221, a second support frame 222, and a second driving member 223. The second moving track 221 is mounted on the first support frame 21 along a second direction. The second support frame 222 is movably mounted on the second moving track 221 along a second direction. The first lifting component 23 is mounted on the second support frame 222. The second driving member 223 is disposed on the second support frame 222 along a second direction and is connected to the second support frame 222 to drive the second support frame 222 to move.

[0034] As an example, the first horizontal moving component 22 includes a second moving track 221, a second support frame 222, and a second driving component 223. The second moving track 221 is a structural component providing linear guidance, which can be implemented using ball bearing rails, sliding rails, or linear modules, providing a precise guiding path for the movement of the second support frame 222. The second support frame 222 is a load-bearing platform that achieves smooth movement through cooperation with the second moving track 221. Specifically, low-friction movement can be achieved through a combination of a slider and a guide rail. Preferably, there are two second moving tracks 221, arranged at intervals along a first direction, both providing movement guidance for the second support frame 222, ensuring smoother and safer movement. The second driving component 223 is a power device capable of generating driving force to move the second support frame 222, which can be driven by a stepper motor, servo motor, or cylinder, ensuring controllability and positioning accuracy during the movement process. For example, the second driving component 223 includes a second motor and a second driving shaft. The second driving shaft is rotatably mounted on the first support frame 21, and the second driving shaft is provided with a driving block connected to the second support frame 222. Alternatively, the second support frame 222 can be movably mounted on the second driving shaft. The second motor is connected to the second driving shaft and drives the second driving shaft to rotate, thereby driving the second support frame 222 to move.

[0035] In this example, by mounting the second moving track 221 on the first support frame 21, a stable guide path is formed using the rigid foundation of the first support frame 21, thus avoiding trajectory deviation caused by external vibration or uneven support. The movable mounting method of the second support frame 222 on the second moving track 221 achieves low-friction sliding through track constraints, making the movement process smoother and more continuous, reducing the shaking or jamming phenomena commonly found in traditional simple slide rails. The first lifting component 23 is directly mounted on the second support frame 222, forming an integrated linkage between lifting action and horizontal movement, simplifying the force transmission path and enhancing the system's anti-interference capability. The direct connection mechanism between the second drive component 223 and the second support frame 222, through precise force application along the second direction, achieves instantaneous response and controllable adjustment of the support frame's movement, avoiding energy loss and response delay caused by long-distance transmission. This integrated design significantly optimizes the accuracy and stability of the small lamp test board 24 during horizontal adjustment, thereby effectively solving the problem of additional errors introduced by inaccurate guidance or unstable drive. The first horizontal movement component 22 not only improves the accuracy and stability of the lamp testing mechanism 2 in the horizontal direction, but also simplifies the overall structure through integrated design, enhancing the system's reliability and automation efficiency. This design is particularly suitable for automated processes that frequently switch test positions, providing higher accuracy and smoother operation for lens testing.

[0036] In one embodiment, reference is made to Figure 4 and Figure 5 The first lifting assembly 23 includes two first lead screw supports 231, a first lead screw 232, a first adjusting block 233, a first linear guide rail 234, a small lamp test board bracket 235, and a third driving member 236. The two first lead screw supports 231 are arranged at intervals along a third direction on the first horizontal moving assembly 22. The two ends of the first lead screw 232 are rotatably mounted on the two first lead screw supports 231, and the first adjusting block 233 is movably mounted on the first lead screw 232. The first linear guide rail 234 is arranged along a third direction on the first horizontal moving assembly 22. The small lamp test board bracket 235 is movably mounted on the first linear guide rail 234 and connected to the first adjusting block 233. The third driving member 236 is connected to one end of the first lead screw 232 and drives the first lead screw 232 to rotate, thereby driving the first adjusting block 233 to move.

[0037] As an example, the first lifting assembly 23 includes two first lead screw supports 231, a first lead screw 232, a first adjusting block 233, a first linear guide rail 234, a small lamp test board bracket 235, and a third driving component 236. The first lead screw support 231 is a structural component used to support and fix the first lead screw 232. It can be implemented using a metal bracket to provide a stable mounting base for the first lead screw 232 and prevent it from shifting or shaking during rotation. The first lead screw 232 is a transmission element that converts rotational motion into linear displacement. It can be implemented using a precision-machined trapezoidal lead screw or ball screw to precisely control the linear displacement during position adjustment. The first adjusting block 233 is a moving component mounted on the first lead screw 232. It can be implemented using a slider structure with internal threads to achieve micron-level displacement control based on the rotation of the first lead screw 232. The first linear guide rail 234 is a guide device that guides the small lamp test board bracket 235 to move in a specific direction. It can be implemented using a ball-bearing linear guide rail or a sliding linear guide rail, constraining the movement trajectory to a third direction to avoid lateral vibration or deviation. Preferably, there are two first linear guide rails 234, which are arranged at intervals to ensure that the small lamp test board bracket 235 can move smoothly and safely. The small lamp test board bracket 235 is a support structure for fixing the small lamp test board 24. It can be implemented using a frame structure made of lightweight aluminum alloy material to ensure that the small lamp test board 24 can be accurately aligned with the lens. The third driving component 236 is a driving device that provides rotational power to the first lead screw 232. It can be implemented using a rotary handle, a stepper motor, or a servo motor, reducing errors caused by manual intervention through automated control.

[0038] In this example, by optimizing the structural design of the first lifting component 23, the problem of inaccurate position adjustment in the small lamp testing mechanism 2 is effectively solved. Two first lead screw supports 231 are spaced apart along a third direction on the first horizontal moving component 22, providing a stable mounting base and ensuring that the first lead screw 232 is not prone to offset or wobbling during rotation, thereby enhancing the rigidity of the overall structure. The two ends of the first lead screw 232 are rotatably mounted on the two first lead screw supports 231. Based on the rotational input of the third driving component 236, the rotational motion is precisely converted into linear displacement. This conversion method avoids the backlash problems common in traditional gear or belt drives, ensuring the continuity and repeatability of position adjustment. The first adjusting block 233 is movably mounted on the first lead screw 232 and directly connected to the small lamp testing board bracket 235. Micrometer-level displacement control is achieved based on the rotation of the first lead screw 232, enabling the small lamp testing board 24 to accurately align with the lens and improving the sensitivity of the test. The first linear guide rail 234 is mounted on the first horizontal moving component 22 along a third direction. The small lamp test board bracket 235 is movably mounted on the first linear guide rail 234 and connected to the first adjusting block 233. This design constrains the movement trajectory to only the third direction, effectively preventing lateral vibration or offset and ensuring the linearity and stability of the movement process. The third driving component 236 is connected to one end of the first lead screw 232, driving the first lead screw 232 to rotate, thereby driving the first adjusting block 233 to move. This achieves automated control, reduces errors caused by manual intervention, and makes the testing process more efficient and reliable. Overall, the synergistic effect of the lead screw and the linear guide rail not only improves the accuracy of position adjustment but also enhances the system's anti-interference capability, providing a stable and reliable environment for lens testing. In addition, when the first lifting component 23 is used in conjunction with the first horizontal moving component 22, it can achieve more complex spatial position adjustments, further improving the flexibility and accuracy of the test.

[0039] In one embodiment, reference is made to Figure 6 The headlight testing mechanism 3 includes a third support frame 31, a second linear guide rail 32, a profile connecting fastener 33, a headlight testing plate 34, and a second lifting assembly 35. The third support frame 31 is installed on the inner bottom wall of the testing chamber 1 and is spaced apart from the small lamp testing mechanism 2 along a first direction. The second linear guide rail 32 is arranged on the third support frame 31 along a third direction. The profile connecting fastener 33 is movably installed on the second linear guide rail 32 along a third direction. The headlight testing plate 34 is installed on the profile connecting fastener 33. The second lifting assembly 35 is arranged on the third support frame 31 and connected to the profile connecting fastener 33. It is used to drive the profile connecting fastener 33 to move so that the headlight testing plate 34 can test the lens.

[0040] As an example, the headlight testing mechanism 3 includes a third support frame 31, a second linear guide rail 32, a profile connecting fastener 33, a headlight testing plate 34, and a second lifting assembly 35. The third support frame 31 is a structural component with stable load-bearing capacity, which can be implemented using a metal frame or a high-strength plastic bracket, providing a stable foundation for the entire headlight testing mechanism 3 and preventing loosening of the overall structure due to external vibration or internal movement. The second linear guide rail 32 is a high-precision guiding device, which can be a ball-bearing linear guide rail or a sliding linear guide rail, ensuring smooth movement of the profile connecting fastener 33 along a third direction and reducing friction and offset errors. Preferably, the third support frame 31 is a rectangular frame, and there are multiple second linear guide rails 32, with at least one second linear guide rail 32 provided on each inner sidewall of the rectangular frame, ensuring smooth and safe movement of the profile connecting fastener 33. The profile connecting fastener 33 is a rigid connector, which can be made of aluminum alloy or stainless steel profiles, firmly fixing the headlight testing plate 34 and maintaining its stable posture. In addition, the second lifting component 35 is a driving device that can be implemented by a screw drive mechanism or a hydraulic lifting mechanism. By precisely controlling the lifting action of the profile connecting fastener 33, the position of the headlight test board 34 can be finely adjusted.

[0041] In this example, the close cooperation between the components of the headlight testing mechanism 3 achieves efficient and accurate testing functions. This not only meets the high-precision requirements of lens performance testing but also significantly shortens testing time and reduces the risk of errors caused by manual intervention, thus providing a reliable guarantee for rapid testing in large-scale production. Specifically, the third support frame 31, as a basic structural component, not only provides a stable installation platform but also optimizes the test space layout through its spacing with the small lamp testing mechanism 2, avoiding interference between adjacent testing mechanisms. The combined design of the second linear guide rail 32 and the profile connecting fastener 33 utilizes the high-precision guiding characteristics of the linear guide rail to ensure the straightness and repeatability of the headlight testing plate 34 in the vertical direction, effectively reducing the offset errors that may be introduced by traditional simple slide rails. Simultaneously, the second lifting assembly 35, through its linkage with the profile connecting fastener 33, achieves micron-level precise lifting control, enabling the headlight testing plate 34 to quickly adapt to the focal length requirements of different lenses, significantly improving testing efficiency. Based on this, the headlight testing mechanism 3 and other testing mechanisms in the testing chamber 1 work together to form a complete testing system, which solves the problem of inaccurate adjustment of the test board position and improves the stability and reliability of the testing process.

[0042] In one embodiment, reference is made to Figure 6The second lifting assembly 35 includes two lead screw assemblies 351, two synchronous pulleys 352, a synchronous belt 353, and a fourth drive component 354. The two lead screw assemblies 351 are symmetrically arranged on the third support frame 31 along a first or second direction, and are respectively located on opposite sides of the profile connecting fastener 33. Each lead screw assembly 351 includes two second lead screw supports 3511, a second lead screw 3512, and a second adjusting block 3513. The two second lead screw supports 3511 are spaced apart along a third direction, and the two ends of the second lead screw 3512 are rotatably mounted on... On the two second lead screw supports 3511, the second adjusting block 3513 is movably mounted on the second lead screw 3512 and connected to the profile connecting fastener 33; each second lead screw 3512 is equipped with a synchronous pulley 352, and the synchronous belt 353 is fitted on the two synchronous pulleys 352; at least one second lead screw 3512 is provided with a fourth driving member 354. When any fourth driving member 354 is working, it drives one synchronous pulley 352 to rotate, and drives the other synchronous pulley 352 to rotate through the synchronous belt 353, so as to drive the two second lead screws 3512 to work synchronously.

[0043] As an example, the second lifting assembly 35 includes two lead screw groups 351, two synchronous pulleys 352, a synchronous belt 353, and a fourth drive component 354. The lead screw group 351 is a transmission device that converts rotary motion into linear motion; it can be a ball screw or a trapezoidal screw to ensure smooth lifting of the profile connecting fastener 33. The synchronous pulleys 352 are toothed transmission components, which can be made of metal or high-strength plastic to achieve precise power transmission. The synchronous belt 353 is a flexible transmission component with a toothed structure, which can be made of rubber or polyurethane to ensure synchronous rotation between the two synchronous pulleys 352. The fourth drive component 354 is a device that provides rotational power; it can be a rotary handle, a stepper motor, or a servo motor to provide driving force for the entire lifting process. The second lifting assembly 35 also includes a tensioning pulley 355, which can adjust the tension of the synchronous belt 353 to prevent it from being too tight or too loose, thus affecting power transmission. Specifically, each synchronous pulley 352 has a tensioning pulley 355 on one side, and either of the two tensioning pulleys 355 can adjust the tension of the synchronous belt 353.

[0044] In this example, two lead screw assemblies 351 are symmetrically arranged on the third support frame 31 and connected to both sides of the profile connecting fastener 33. This layout ensures that the lifting force is evenly distributed on both sides of the profile connecting fastener 33, avoiding the risk of tilting that may be caused by unilateral force. Each lead screw assembly 351 is equipped with a synchronous pulley 352 connected by a synchronous belt 353. When one synchronous pulley 352 rotates, the synchronous belt 353 forces the other synchronous pulley 352 to rotate synchronously, thus ensuring that the movement trajectories of the two lead screw assemblies 351 remain consistent. At least one lead screw assembly 351 is equipped with a fourth drive component 354 (power can be provided to one fourth drive component 354 or both fourth drive components 354 can be powered simultaneously). When any drive component is working, power is transmitted through the synchronous belt 353, enabling the two lead screw assemblies 351 to move synchronously under a single drive source. This design not only simplifies the drive structure but also fundamentally eliminates the hidden dangers of asynchronous multiple drive sources, ensuring the smooth lifting and lowering of the profile connecting fastener 33, and ultimately improving the positioning accuracy and testing stability of the headlight test board 34. Furthermore, the symmetrically arranged lead screw assembly 351 and synchronous belt 353 transmission system effectively solves the positioning deviation problem caused by asynchronous movement, significantly improving the accuracy of the test light and the reliability of the lens test results.

[0045] In one embodiment, reference is made to Figure 6 Each lead screw assembly 351 includes two second lead screw supports 3511, a second lead screw 3512, and a second adjusting block 3513. The second lead screw supports 3511 are structural components used to support and position the second lead screw 3512. They can be fixed brackets made of metal, providing a stable support foundation for the second lead screw 3512 and preventing swaying or offset due to insufficient support force. The second lead screw 3512 is a transmission component that converts rotary motion into linear motion. It can achieve precise displacement control through a threaded connection, ensuring the smoothness and accuracy of lifting and lowering movements. The second adjusting block 3513 is a sliding component installed on the second lead screw 3512. It can form a threaded connection with the second lead screw 3512 through a nut structure, thereby realizing the conversion of linear displacement. The direct connection mechanism reduces transmission errors and improves the response speed and accuracy of position adjustment.

[0046] In this example, the reasonable spacing of the two second lead screw supports 3511 along a third direction ensures that the second lead screw 3512 receives uniform support force distribution during lifting and lowering, effectively avoiding bending or vibration problems caused by support points being too close or too far apart, thereby improving the rigidity of the overall structure. Simultaneously, the two ends of the second lead screw 3512 are rotatably mounted on the two second lead screw supports 3511. This design, combined with low-friction rotational characteristics, makes the driving process smoother and more continuous, reducing energy loss and the risk of jamming. Furthermore, the direct connection mechanism between the second adjusting block 3513 and the profile connecting fastener 33 utilizes the coupling relationship between the lead screw rotation and the adjusting block movement to achieve efficient position adjustment, ensuring that the headlight test plate 34 can be stably aligned with the lens, thereby reducing the deviation error of the test light. Based on this, the second lifting assembly 35 works together with the first support frame 21, the third support frame 31 and other components to form a complete lifting and adjustment system, which further improves the reliability and consistency of the headlight testing process; it not only solves the problem of swaying and offset that may occur in the lead screw assembly 351 during lifting and lowering, but also significantly improves the positioning accuracy of the headlight test board 34, thereby ensuring the accuracy and stability of the test results.

[0047] In one embodiment, reference is made to Figure 7 and Figure 8 The gray board testing mechanism 4 includes a fourth support frame 41, a second horizontal moving component 42, a third lifting component 43, and a gray board testing plate 44. The fourth support frame 41 is installed on the inner bottom wall of the testing chamber 1 and is spaced apart from the headlight testing mechanism 3 along a first direction. The second horizontal moving component 42 is disposed on the fourth support frame 41 along the first direction, and the third lifting component 43 is disposed on the second horizontal moving component 42 along a third direction. The gray board testing plate 44 is installed on the third lifting component 43. The second horizontal moving component 42 and the third lifting component 43 cooperate to adjust the position of the gray board testing plate 44 so that the gray board testing plate 44 can test the lens.

[0048] As an example, the gray board testing mechanism 4 includes a fourth support frame 41, a second horizontal moving component 42, a third lifting component 43, and a gray board testing plate 44. The fourth support frame 41 is the basic frame providing stable support for the entire gray board testing mechanism 4. It can be implemented using a rectangular frame structure made of spliced ​​metal profiles, ensuring the independence and stability of the gray board testing mechanism 4 within the testing chamber 1. The second horizontal moving component 42 is a transmission device capable of precise displacement along a first direction. It can be implemented using a screw-slider mechanism or a linear motor-driven slide rail system to quickly track the lens position and complete horizontal alignment. The third lifting component 43 is a mechanical structure capable of fine adjustment in the vertical direction. It can be implemented using a screw-nut pair with a guide rail or a pneumatic telescopic rod, adapting to the height differences of different lenses and improving the versatility of the test. The gray board testing plate 44 is the core component for performing actual testing tasks. It is dynamically positioned by being mounted on the third lifting component 43, ensuring precise alignment of the testing surface with the lens optical axis.

[0049] In this example, the gray board testing mechanism 4 achieves efficient and accurate testing functions through the organic cooperation between its components. Working together with other testing mechanisms within the testing chamber 1, it improves the overall efficiency and accuracy of lens performance testing, meeting the demands for rapid and precise testing in large-scale production. The fourth support frame 41, as the foundation of the overall structure, not only provides a reliable installation benchmark but also avoids spatial conflicts with other testing mechanisms. The second horizontal movement component 42, based on the characteristic of the loading and positioning mechanism 5 driving the lens to move along the first direction, is designed with displacement capabilities along the first direction, significantly reducing the time spent on repeated adjustments due to directional mismatch. The third lifting component 43, through its fine vertical adjustment capability, solves the cumbersome problem of manually replacing the support bracket required by traditional fixed structures. The cooperation of these two components forms a horizontal and vertical dual-dimensional linkage adjustment mechanism. This mechanism can quickly respond to and stably position itself to the optimal testing point according to the real-time changes in lens position, effectively reducing operational complexity and avoiding testing errors caused by inaccurate positioning.

[0050] In one embodiment, reference is made to Figure 7 and Figure 8 The second horizontal moving component 42 includes a third moving track 421, a fifth support frame 422, and a fifth driving member 423; the third moving track 421 is mounted on the fourth support frame 41 along a first direction; the fifth support frame 422 is movably mounted on the third moving track 421 along the first direction, and the third lifting component 43 is mounted on the fifth support frame 422; the fifth driving member 423 is disposed on the fourth support frame 41 along the first direction and is connected to the fifth support frame 422, for driving the fifth support frame 422 to move.

[0051] As an example, the second horizontal moving component 42 includes a third moving track 421, a fifth support frame 422, and a fifth driving component 423. The third moving track 421 is a structure that provides stable guidance along a specific direction, and can be implemented using linear guides, chutes, or ball bearing tracks. It provides precise path constraints for the movement of the fifth support frame 422, thereby ensuring the positioning accuracy of the gray board test plate 44 in the horizontal direction. Preferably, there are two third moving tracks 421, arranged at intervals along the second direction, both providing movement guidance for the fifth support frame 422, ensuring smoother and safer movement. The fifth support frame 422 is an intermediate structure that carries and transmits motion, and can achieve smooth movement on the track using sliders, rollers, or magnetic levitation devices. It converts driving force into displacement and maintains the stability of the overall structure. The fifth driving component 423 is a device that provides power output, and can be implemented using servo motors, stepper motors, or cylinders. It provides controllable power support for the entire movement process. For example, the fifth driving component 423 includes a third motor and a third driving shaft. The third driving shaft is rotatably mounted on the fourth support frame 41, and the third driving shaft is provided with a driving block connected to the fifth support frame 422. Alternatively, the fifth support frame 422 can be movably mounted on the third driving shaft. The third motor is connected to the third driving shaft and drives the third driving shaft to rotate, thereby driving the fifth support frame 422 to move.

[0052] In this example, the third moving track 421 is directly fixed to the fourth support frame 41, forming a rigid connection structure. This design effectively avoids the problem of trajectory deviation caused by loosening of the support structure during the test. The movable installation of the fifth support frame 422 on the third moving track 421 utilizes a track guiding mechanism to achieve smooth and continuous displacement adjustment, while reducing sliding friction and shaking. The integrated design of the third lifting component 43 and the fifth support frame 422 allows the lifting function to be synchronized with horizontal movement, ensuring the coordination of the overall structure. The direct connection between the fifth driving component 423 and the fifth support frame 422 ensures the accurate transmission of driving force along the movement direction, improving the sensitivity of the movement response and the accuracy of the endpoint positioning. Through the above technical solutions, not only is the problem of inaccurate horizontal positioning of the gray board test plate 44 solved, but the stability and repeatability of the test process are also improved, thereby ensuring the reliability of the test results. The second horizontal moving component 42 forms an organic cooperation with the other components in the gray board test mechanism 4. The fourth support frame 41 serves as the basic installation platform, providing a stable support foundation for the entire mobile system. The third lifting component 43, through linkage with the fifth support frame 422, enables the precise positioning of the gray board test plate 44 in three-dimensional space. This multi-layered structural design effectively solves the positional deviation problem that may occur during gray board testing and significantly improves the overall performance of the testing device.

[0053] In one embodiment, reference is made to Figure 7 and Figure 8 The third lifting assembly 43 includes two third lead screw supports 431, a third lead screw 432, a third adjusting block 433, a third linear guide rail 434, a gray board test plate bracket 435, and a sixth driving member 436. The two third lead screw supports 431 are arranged at intervals along a third direction on the second horizontal moving assembly 42. The two ends of the third lead screw 432 are rotatably mounted on the two third lead screw supports 431, and the third adjusting block 433 is movably mounted on the third lead screw 432. The third linear guide rail 434 is arranged along a third direction on the second horizontal moving assembly 42. The gray board test plate bracket 435 is movably mounted on the third linear guide rail 434 and connected to the third adjusting block 433. The sixth driving member 436 is connected to one end of the third lead screw 432, driving the third lead screw 432 to rotate, thereby driving the third adjusting block 433 to move.

[0054] As an example, the third lifting assembly 43 includes two third lead screw supports 431, a third lead screw 432, a third adjusting block 433, a third linear guide rail 434, a gray board test plate bracket 435, and a sixth driving component 436. The third lead screw support 431 is a structural component used to support and fix the third lead screw 432. It can be implemented using a rigid bracket made of metal, providing a stable support foundation and avoiding axial bending or vibration problems caused by single-point fixing. The third lead screw 432 is a transmission element that converts rotary motion into linear motion. It can be implemented using a high-precision ball screw or trapezoidal lead screw, ensuring linear accuracy of displacement conversion and micron-level adjustment capability. The third adjusting block 433 is a moving component installed on the third lead screw 432. It can be implemented using a slider structure with internal threads, converting rotary motion into precise linear displacement through threaded engagement. The third linear guide rail 434 is a structural component that provides a rigid guide path for motion. It can be implemented using a ball linear guide or a sliding guide, forcibly constraining the adjusting block to move only in the vertical direction, eliminating lateral force interference. Preferably, there are two third linear guide rails 434, arranged at intervals, which ensures that the gray board test plate bracket 435 can move smoothly and safely. The gray board test plate bracket 435 refers to the connecting component used to support the gray board test plate 44 and transmit displacement. It can be implemented with a lightweight, high-strength aluminum alloy frame structure to ensure that the test plate remains parallel to the lens optical axis during movement. The sixth driving component 436 is a device that provides controllable rotational power. It can be implemented with a rotary handle, a stepper motor, or a servo motor. Combined with the mechanical gain effect of the lead screw, it achieves smooth and shock-free movement of the adjusting block.

[0055] In this example, two third lead screw supports 431 are spaced apart along a third direction on the second horizontal moving assembly 42, forming a symmetrical support structure, thus providing a stable foundation for the entire transmission system. The two ends of the third lead screw 432 are rotatably mounted on the supports, ensuring that the rotational motion is evenly distributed throughout the entire length of the lead screw, reducing eccentricity errors caused by uneven torque. The third adjusting block 433 converts the rotational motion into precise linear displacement through a threaded connection; its movement directly depends on the lead screw pitch, achieving repeatability at the micrometer level. The third linear guide rail 434 is set along a third direction on the second horizontal moving assembly 42, providing a rigid guide path for the motion, forcibly constraining the adjusting block to move only in the vertical direction, eliminating lateral force interference, and ensuring a strictly linear motion trajectory. The gray board test plate bracket 435 is movably mounted on the third linear guide rail 434 and connected to the third adjusting block 433. This connection method allows the bracket to directly inherit the displacement of the adjusting block, while the guiding effect of the guide rail maintains the test plate parallel to the lens optical axis during movement, preventing inaccuracy of the test surface caused by tilting. The sixth driving component 436 is connected to one end of the third lead screw 432 and drives it to rotate. Controllable rotational power is provided via a motor or stepper motor. Combined with the mechanical gain effect of the lead screw, smooth, shock-free movement of the adjusting block is achieved, adapting to speed and position requirements in different testing scenarios and avoiding inertial errors caused by sudden starts and stops. Overall, the combined mechanism of the lead screw and guide rail not only improves adjustment accuracy but also suppresses external vibration interference in the testing process through structural rigidity, ensuring consistent results in gray board testing under complex production environments.

[0056] In one embodiment, reference is made to Figure 10 The lens testing device also includes a relay lens mechanism 6, which includes a sixth support frame 61, a fourth moving track 62, a relay lens positioning frame 63, a relay lens body 64, and a seventh driving component 65. The sixth support frame 61 is disposed on the inner bottom wall of the test chamber 1 along the second direction and is disposed opposite to the headlight testing mechanism 3. The fourth moving track 62 is disposed on the sixth support frame 61 along the second direction, and the relay lens positioning frame 63 is movably mounted on the fourth moving track 62 along the second direction. The relay lens body 64 is mounted on the relay lens positioning frame 63 and is located between the headlight testing mechanism 3 and the lens, and is used to guide and adjust the test light between the headlight testing mechanism 3 and the lens. The seventh driving component 65 is disposed on the fourth moving track 62 along the second direction and is connected to the relay lens positioning frame 63, and is used to drive the relay lens positioning frame 63 to move.

[0057] As an example, the lens testing device also includes a relay mirror mechanism 6, which is an optical component capable of guiding and adjusting the light path. It can be implemented using optical elements such as plane mirrors, prisms, or lens groups. Through optical reflection or refraction characteristics, it dynamically corrects the direction and uniformity of the light, thereby improving testing accuracy (e.g., a convex lens is used to magnify the light). The second direction is typically perpendicular to the first direction of lens movement. This directional arrangement ensures that the adjustment action of the relay mirror is independent of the movement trajectory of the loading and positioning mechanism 5, avoiding mechanical vibration or displacement interference with light calibration during lens positioning. The relay mirror mechanism 6 is positioned opposite the headlight testing mechanism 3, forming a directly facing optical path, shortening the light transmission distance and reducing the intrusion of ambient stray light, allowing the test light to be more accurately focused on the lens testing area.

[0058] In this example, the introduction of the repeater mechanism 6 not only solves the problem of ineffective guidance and adjustment of the test light, but also significantly improves the accuracy and consistency of headlight testing, providing a reliable guarantee for the comprehensive evaluation of lens performance. The repeater mechanism 6 is arranged along the second direction within the test chamber 1, forming a stable optical alignment with the headlight testing mechanism 3, ensuring that the test light acts on the lens with constant intensity and angle. Due to the presence of the repeater mechanism 6, the test light emitted by the headlight testing mechanism 3, after being guided by the repeater, can effectively suppress light scattering problems caused by air disturbances or reflections from the chamber 12, thereby improving the reliability and consistency of the test results. Furthermore, the repeater mechanism 6 also forms a good working relationship with the loading and positioning mechanism 5, the headlight testing mechanism 3, etc., further optimizing the stability and efficiency of the overall testing process.

[0059] In one embodiment, reference is made to Figure 10The repeater mechanism 6 includes a sixth support frame 61, a fourth moving track 62, a repeater positioning frame 63, a repeater body 64, and a seventh drive component 65. The sixth support frame 61 is the foundation component providing stable support for the entire repeater mechanism 6. It can be implemented using a metal frame structure to ensure the repeater mechanism 6 remains stable during testing and prevent external vibrations or interference from affecting the light guiding accuracy. The fourth moving track 62 can be understood as a linear guide device, specifically in the form of a ball bearing slide or a linear bearing guide, enabling the repeater positioning frame 63 to achieve smooth and precise linear movement along the second direction. The repeater positioning frame 63 is the key component that supports the repeater body 64 and realizes its position adjustment. It achieves its movement function by cooperating with the fourth moving track 62 through a slider, dynamically adjusting the spatial position of the repeater body 64 according to testing requirements. The seventh drive component 65 can be a stepper motor or a servo motor, which is connected to the repeater positioning frame 63 through a transmission mechanism to achieve automated drive, reduce manual intervention, and improve adjustment efficiency and accuracy. For example, the seventh driving component 65 includes a fourth motor and a fourth driving shaft. The fourth driving shaft is rotatably mounted on the fourth moving track 62, and the fourth driving shaft is provided with a driving block connected to the relay mirror positioning frame 63, or the relay mirror positioning frame 63 is movably mounted on the fourth driving shaft. The fourth motor is connected to the fourth driving shaft and drives the fourth driving shaft to rotate, thereby driving the relay mirror positioning frame 63 to move.

[0060] In this example, the sixth support frame 61 is fixed to the inner bottom wall of the test chamber 1, providing a stable support foundation for the entire repeater mechanism 6, thereby effectively avoiding the problem of light path deviation caused by external vibration during the test. The fourth moving track 62 extends along the second direction, allowing the repeater positioning frame 63 to move flexibly in a specific direction. This design optimizes the spatial relationship between the headlight test mechanism 3 and the lens, facilitating precise control of the lateral offset of the light path. Through cooperation with the fourth moving track 62, the repeater positioning frame 63 realizes the dynamic adjustment function of the repeater body 64. It can change the spatial coordinates of the repeater body 64 in real time according to different lens models or test parameters, thereby compensating for differences in optical characteristics and reducing test errors. The repeater body 64 is located between the headlight test mechanism 3 and the lens. The movement of the repeater positioning frame 63 optimizes its position, ensuring that the test light can be accurately focused and transmitted, avoiding the impact of light scattering or distortion on image quality. The seventh drive component 65 connects to the repeater positioning frame 63, eliminating the tediousness and subjective bias of manual operation through automated drive, significantly improving the speed and consistency of the light adjustment process. By introducing the movable repeater mechanism 6, the problem of light path deviation caused by the inability of traditional fixed repeaters to adapt to different test conditions is solved.

[0061] In one embodiment, reference is made to Figure 1The test chamber 1 includes a base 11 and a chamber body 12. The chamber body 12 is mounted on the base 11, and the two together form a test space for placing the small light test mechanism 2, the large light test mechanism 3, the gray board test mechanism 4, and the feeding and positioning mechanism 5. The chamber body 12 is provided with an automatic accordion door 13, which is correspondingly set with the feeding and positioning mechanism 5. The chamber body 12 is also provided with a safety light curtain 7, a three-color indicator light 8, a display screen 9, and a control component 10. The safety light curtain 7 is located on the side of the automatic accordion door 13, the three-color indicator light 8 is used to indicate the test working status, the display screen 9 is used to display the test results, and the control component 10 is used to control the working status of the test device.

[0062] As an example, test chamber 1 includes a base 11 and a chamber body 12. The base 11, serving as the fundamental support component, is typically made of rigid materials, providing a stable mounting platform for the entire testing device. The chamber body 12 is connected to the base 11 via bolts, welding, or snap-fit ​​fasteners, forming a sealed testing space for housing the small light testing mechanism 2, the headlight testing mechanism 3, the gray board testing mechanism 4, and the loading and positioning mechanism 5. This space isolates the device from external environmental interference, ensuring the stability and reliability of the testing process. The base 11 has casters and a fixed support at its bottom. The casters facilitate user movement of the entire device, while the fixed support provides better stability. The chamber body 12 has an observation door, allowing staff to easily monitor the testing process within test chamber 1 and facilitating the adjustment, inspection, and maintenance of the various mechanisms within test chamber 1.

[0063] An automatic accordion door 13 is provided on the chamber 12, corresponding to the loading and positioning mechanism 5. The automatic accordion door 13 is a flexible and retractable door structure that can adopt a multi-layer folding design and can be opened and closed by motor drive or manual operation. This design achieves dynamic isolation of the test space, minimizing the impact of the external environment on the test process while ensuring lens transmission efficiency.

[0064] The chamber 12 is also equipped with a safety light curtain 7, a three-color indicator light 8, a display screen 9, and a control unit 10. The safety light curtain 7 is located on the side of the automatic accordion door 13. The safety light curtain 7 is a photoelectric sensing device, typically composed of a transmitter and a receiver. It can use infrared detection technology to promptly issue an alarm signal and interrupt the testing process when personnel approach, thus ensuring operational safety. The three-color indicator light 8 is a multi-state display device that visually reflects the equipment's operating status through changes in red, yellow, and green colors; for example, a green light indicates a test is complete, a yellow light indicates a test is in progress, and a red light indicates a test failure. The display screen 9 typically uses LCD technology to present test data and results in real time. The control unit 10 can be in the form of physical buttons or a touchscreen (e.g., a dual-button start button, an emergency stop button, a reset button, or a keyboard). Its main function is to provide users with a convenient operating interface for adjusting test parameters and monitoring the test process.

[0065] In this example, the combined structure of base 11 and chamber 12 creates an independent and stable testing environment, effectively shielding the test results from interference from external light and temperature fluctuations. The linkage design of the automatic accordion door 13 and the loading and positioning mechanism 5 enables intelligent management of the testing space, opening only when necessary and significantly reducing the impact of sudden environmental changes on testing accuracy. The carefully designed position of the safety light curtain 7 ensures timely response to personnel approach while avoiding frequent shutdowns due to accidental triggering. Simultaneously, the tri-color indicator light 8, display screen 9, and control unit 10 together constitute a complete human-machine interface system. The tri-color indicator light 8 uses intuitive color changes to indicate equipment status, allowing operators to understand the operating status without needing to view complex interfaces. The display screen 9 displays test data in real time, improving work efficiency and reducing errors that may arise from manual recording. The integrated design of the control unit 10 simplifies the operation process, enabling users to quickly adjust test parameters and improve overall testing efficiency. Test Chamber 1 not only provides a stable testing environment, but also forms a complete testing solution through an intelligent gate control system, reliable safety protection devices, and an intuitive human-computer interaction interface. It addresses the problems of environmental interference, safety hazards, and inconvenience in operation that exist in traditional testing devices, and significantly improves testing accuracy and operational safety through multiple optimization measures.
