Description

Technical Field

[0001] This application relates to the field of tooling testing technology, and more specifically, to a testing system. Background Technology

[0002] In various types of camera devices, a transmission mechanism is usually used to adjust the position of the lens or image sensor in the optical path in order to achieve the corresponding focusing process and meet the focusing requirements of various shooting modes.

[0003] However, since transmission mechanisms typically include multiple meshing mechanical parts, such as meshing worm gears and worm shafts, backlash during operation—for example, during forward and reverse rotation—can cause motor idle travel due to assembly factors and the fact that the worm gears and worm shafts are not 100% meshed. This backlash affects the accuracy of the focusing position and consequently negatively impacts the data quality captured by the camera. Therefore, it is currently difficult to control the magnitude of backlash during the assembly process of transmission mechanisms, leading to unstable performance and an inability to achieve high-precision position adjustment. Utility Model Content

[0004] In view of this, the purpose of this application is to provide a testing system to improve the problem of unstable performance of transmission mechanisms in the prior art.

[0005] To address the aforementioned problems, in a first aspect, embodiments of this application provide a testing system, the system comprising: a fixed platform, a measuring component, and a transmission component;

[0006] The fixed platform is used to fix the measuring component and the rotating component being tested; the first end of the transmission component is fixed to the rotating component, and the second end of the transmission component is in static contact with the test end of the measuring component.

[0007] The transmission component is used to drive the rotating component to move, and the measuring component is used to measure the travel distance value based on the movement of the rotating component.

[0008] In the above implementation process, a transmission component fixed on the rotating component drives the rotating component to move, triggering a measuring component that abuts against the transmission component to record the corresponding travel value of the transmission component during its movement. This enables the testing of the hysteresis of the rotating component, allowing the determination of whether the rotating component should be put into normal use in the corresponding camera equipment based on the detected hysteresis. The ability to test the hysteresis of the rotating component before its formal use effectively reduces the complexity of the testing system, thereby reducing the cost of the components required for testing. The testing improves the stability of the rotating component during its formal use, effectively enhancing the stability of the rotating component's movement and reducing the adverse effects of hysteresis caused by movement on the position adjustment accuracy. This, in turn, improves the focusing accuracy of the camera equipment and further optimizes the quality of the shooting data obtained by the camera equipment.

[0009] Optionally, a first area is provided on the fixed platform;

[0010] The system further includes: a first sliding fastener;

[0011] The measuring element is slidably fixed in the first region by the first sliding fastener.

[0012] In the above implementation process, a first area for fixing the measuring component can be set on the fixed platform. In order to enable the test end of the measuring component to properly abut with the second end of the transmission component, a corresponding first sliding fixing component can also be set in the test system to slide and fix the measuring component in the first area through the first sliding fixing component, which effectively improves the effectiveness of the abutment between the measuring component and the transmission component, thereby improving the effectiveness of motion measurement based on abutment.

[0013] Optionally, the fixed position of the measuring element is determined based on the rest position of the second end of the transmission element.

[0014] In the above implementation process, considering that the direction and length of the transmission component may change under different test scenarios, the rest position of the second end of the transmission component may also be different. The fixed position of the measuring component can be determined according to the actual rest position of the second end of the transmission component. By dynamically adjusting the position of the measuring component, it can achieve static contact with the second end of the transmission component at various different rest positions, thereby performing effective motion measurement through contact.

[0015] Optionally, a second area is provided on the fixed platform;

[0016] The system also includes: a second fastener;

[0017] The rotating component is fixed in the second region by the second fixing component;

[0018] The distribution positions of the second region and the first region are determined based on the contact geometry of the transmission component and the test end.

[0019] In the above implementation process, a second region for fixing the rotating component can also be set on the fixed platform. To improve the stability of the rotating component during testing in the second region, a corresponding second fixing component can also be set in the testing system to fix the rotating component in the second region, effectively reducing adverse situations such as shaking and displacement of the rotating component during testing that affect the testing accuracy. Furthermore, the distribution positions of the first and second regions can be determined according to the contact geometry of the transmission component and the test end, so that the test end of the measuring component fixed in the first region can properly contact the second end of the transmission component fixed on the rotating component in the second region, reducing the adverse situation of failure to properly contact the test due to a large distribution distance, and can be dynamically adjusted during testing, making it suitable for various different testing scenarios.

[0020] Optionally, the abutment geometry includes: a first pointing direction between the first end and the second end of the transmission member is perpendicular to a second pointing direction of the test end.

[0021] In the above implementation process, the contact geometry may include a first pointing direction between the first end and the second end of the transmission component, which is perpendicular to the second pointing direction of the test end. Therefore, the distribution position, size and other distribution of the two regions can be set and adjusted so that the two pointing directions of the transmission component and the measuring component fixed in the two regions can be perpendicular to each other, so as to achieve normal contact measurement and adapt to a variety of different test scenarios.

[0022] Optionally, the first end of the transmission member has a fixed shaft, and the transmission member is interference-fitted with a fixed hole on the rotating member through the fixed shaft.

[0023] In the above implementation process, a fixed shaft can be provided on the first end of the transmission component, and a corresponding fixing hole can be provided on the rotating component. The first end of the transmission component is fixed to the rotating component by the engagement of the fixed shaft and the fixing hole. Furthermore, in order to reduce adverse situations such as gaps or looseness between the transmission component and the rotating component, the assembly structure between the fixed shaft and the fixing hole can be an interference fit structure. This improves the stability of the transmission component fixed on the rotating component, reduces the adverse effects of loosening or sliding of the transmission component on the motion measurement, and further improves the accuracy and effectiveness of the measured travel value.

[0024] Optionally, the transmission component includes a rigid rod-like structure, and the measuring component includes a numerical display.

[0025] The hysteresis detection angle of the rotating component is:

[0026] θ = arctan(H / L);

[0027] Wherein, θ is the hysteresis detection angle, H is the travel value measured by the numerical table, and L is the length of the rod-shaped structure.

[0028] In the above implementation process, the transmission component can include a rigid rod-like structure, effectively reducing the adverse effects of deformation of the transmission component on the measured travel value. The movement of the first end can be amplified by the second end of the transmission component, thereby amplifying the hysteresis present on the rotating component. By amplifying the hysteresis present on the rotating component through the movement of the rigid rod-like structure, the hysteresis detection angle corresponding to the rotating component can be calculated based on the measured travel value and the length of the rod-like structure. This effectively improves the accuracy of hysteresis detection on the rotating component, effectively reduces the complexity of the system during testing, and thus reduces the component costs required for testing.

[0029] Optionally, the system further includes: a focusing assembly and a third fixing member;

[0030] The focusing assembly and the third fixing member are fixed on the fixing platform, and the focusing assembly and the third fixing member are arranged opposite to each other;

[0031] The third fastener is used to secure the lens assembly and / or the imaging sensor;

[0032] The focusing component is used to provide a focused image for the lens assembly and / or the imaging sensor.

[0033] In the above implementation process, considering that during the assembly of camera equipment, due to factors such as backlash, the actual focus position of the lens assembly and / or imaging sensor adjusted by the rotating component may be inconsistent, the lens assembly and / or imaging sensor adjusted by the rotating component may require a long focusing time during formal use. To shorten the time required for the user's first focusing after receiving the device, a focusing component and a third fixing component can be set up on a fixed platform in the test system. The lens assembly and / or imaging sensor are fixed by the third fixing component, and the focusing component provides the corresponding focus image for the lens assembly and / or imaging sensor. This structure of the focusing component and the third fixing component allows for pre-focusing testing of the lens assembly and / or imaging sensor before formal use, effectively reducing the time required for focusing during formal use and further optimizing the user experience.

[0034] Optionally, the focusing assembly includes: a calibration plate and a relay lens assembly;

[0035] The calibration plate, the relay lens assembly, and the third fixing member are fixed on the fixing platform;

[0036] The first position of the calibration plate, the second position of the relay lens assembly, and the third position of the third fixing member are arranged in a straight line.

[0037] In the above implementation process, in order to simulate the corresponding shooting mode, the focusing component may include a calibration plate that provides the image and a relay lens component that simulates the distance. The calibration plate, the relay lens component and the third fixing component can be fixed on the fixing platform in sequence, and the fixing positions of the three components are arranged in a straight line to realize the pre-focusing processing of the straight distance, which effectively improves the success rate of the pre-focusing processing and the effectiveness of the focus position.

[0038] Optionally, the fixed platform is provided with a slide rail, and the slide rail is provided with a plurality of sliding elements;

[0039] The calibration plate, the relay mirror assembly, and the third fixing member are slidably fixed on the slide rail via the sliding member.

[0040] In the above implementation process, in order to adapt to the focusing requirements of various different models and types of lens assemblies and / or imaging sensors, a slide rail and corresponding sliding parts can also be set on the fixed platform. Through the sliding fixed structure, the specific positions of the calibration plate, relay lens assembly and third fixing part on the slide rail can be adjusted according to the specific situation of the lens assembly and / or imaging sensor, so as to realize adjustable pre-focusing processing and meet the pre-focusing requirements of various different devices.

[0041] In summary, the embodiments of this application provide a testing system that can test the backlash of a rotating component before it is put into formal use. This effectively reduces the complexity of the testing system, thereby reducing the cost of components required for testing. By testing, the stability of the rotating component during its movement under formal use is improved, effectively enhancing the stability of the rotating component during its movement and reducing the adverse effects of backlash caused by movement on the position adjustment accuracy. This, in turn, improves the focusing accuracy of the camera equipment and further optimizes the quality of the shooting data obtained by the camera equipment. Attached Figure Description

Detailed Implementation

[0047] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the scope of protection of the embodiments of this application.

[0048] Because transmission mechanisms typically include multiple meshing mechanical parts, such as meshing worm gears and worm shafts, which offer advantages like compact structure, lightweight design, reverse self-locking, and large transmission ratios, a certain amount of backlash is required during operation. Insufficient backlash can cause jamming, while excessive backlash can result in excessive motor idle travel, affecting the accuracy of position adjustment using the transmission mechanism. During the movement of the transmission mechanism, such as during forward and reverse rotation, backlash can cause motor idle travel due to assembly factors and the worm gear not being 100% meshed, affecting the accuracy of the focusing position and thus negatively impacting the data quality obtained by the camera. Therefore, it is currently difficult to control the magnitude of backlash during the assembly process of transmission mechanisms, leading to unstable performance and an inability to achieve high-precision position adjustment.

[0049] To address the aforementioned issues, this application provides a testing system capable of testing the backlash of a rotating component before its formal use. This effectively reduces the complexity of the testing system, thereby minimizing the cost of components required for testing. By testing, the system improves the stability of the rotating component during its formal use, effectively enhancing its stability and reducing the adverse effects of backlash caused by movement on position adjustment accuracy. This, in turn, improves the focusing accuracy of the camera equipment and further optimizes the quality of the captured data obtained by the camera equipment.

[0050] Please see Figure 1 , Figure 1 This is a schematic diagram of a testing system provided in an embodiment of the present application. The testing system may include: a fixed platform 100, a measuring component 200, and a transmission component 300.

[0051] Optionally, the fixed stage 100 can be a table-like structure such as a workbench or tooling table. The fixed stage 100 is used to fix the measuring component 200 and the rotating component A being tested, so as to provide a uniform and stable working environment for the measuring component 200 and the rotating component A.

[0052] In this design, the first end of the transmission component 300 is fixed to the rotating component A, and the second end of the transmission component 300 is stationarily in contact with the test end of the measuring component 200. The transmission component 300 can drive the rotating component A to move, and the movement is transmitted to the contacting measuring component 200 through the contact. The measuring component 200 can measure the travel distance value based on the movement of the rotating component A. By driving the rotating component A to move, the measuring component 200, which is in contact with the transmission component 300, records the travel distance value corresponding to the movement of the transmission component 300, thereby testing the hysteresis of the rotating component A. Based on the detected hysteresis, it can be determined whether the rotating component A should be put into normal use in the corresponding camera equipment.

[0053] It should be noted that the rotating component A being tested can be a worm gear or similar structure in a transmission mechanism. The transmission component 300 fixed on the rotating component A can be set as a corresponding angle conversion component. Since there is backlash inside the rotating component A, which can be externally manifested as the rotating component A having a certain degree of rotational freedom, the transmission component 300 can be fixed at the rotation center of the rotating component A. Pressure can be applied to the transmission component 300 to make it rotate around the rotation center, thereby driving the fixedly connected rotating component A to move. This converts the rotational degree of freedom of the rotating component A into the rotational degree of freedom of the transmission component 300, thus realizing the detection of backlash.

[0054] For example, the measuring element 200 can be set as a device with numerical testing function, such as a digital dial indicator or a digital micrometer, so that the test end of the measuring element 200 can be driven to move accordingly by the movement of the second end of the transmission element 300, and the corresponding value is recorded to characterize the movement range of the transmission element 300 as the travel value.

[0055] exist Figure 1 In the illustrated embodiment, the backlash of rotating component A can be tested before it is put into formal use, which effectively reduces the complexity of the system during testing, thereby reducing the cost of components required for testing. The test improves the stability of rotating component A during its movement when it is put into formal use, effectively improving the stability of rotating component A during its movement and reducing the adverse effects of backlash caused by movement on the position adjustment accuracy, thereby improving the focusing accuracy of the camera device and further optimizing the quality of the shooting data obtained by the camera device.

[0056] Optionally, please refer to Figure 2 , Figure 2 This is a schematic diagram of another testing system provided in an embodiment of this application. A first region D1 may be provided on the fixed platform 100. The testing system may further include a first sliding fixing member 410, through which the measuring member 200 is slidably fixed in the first region D1. The fixed platform 100 may have a first region D1 for fixing the measuring member 200. Furthermore, to ensure proper contact between the test end of the measuring member 200 and the second end of the transmission member 300, the testing system may also include a corresponding first sliding fixing member 410. This effectively improves the effectiveness of the contact between the measuring member 200 and the transmission member 300, thereby enhancing the effectiveness of motion measurement based on contact.

[0057] Optionally, a groove area or protrusion of corresponding size and shape can be set on the fixed stage 100 as the first area D1 according to the shape and size of the measuring element 200. For example, if the body of the measuring element 200 is a circular structure with a diameter of 10cm, the first area D1 can be set as a rectangular area with a width (parallel to the direction of the test end) of 15cm and a length (perpendicular to the direction of the test end) of 20cm, so as to provide sufficient sliding adjustment range for the measuring element 200 in the height and width directions.

[0058] For example, the first sliding fixing member 410 can be configured as a pulley, slider, or other structure with sliding function. Correspondingly, a slide rail 530 or other structure can be configured in the first region D1 to cooperate with the first sliding fixing member 410 to achieve sliding fixation. Furthermore, a buckle or other structure can be added to the pulley, slider, or other structure to fix it when it slides to a suitable position.

[0059] It should be noted that the fixed position of the measuring component 200 can be determined based on the resting position of the second end of the transmission component 300. Considering that the pointing direction, length, etc. of the transmission component 300 may change under different test scenarios, the resting position of the second end of the transmission component 300 may also be different. The fixed position of the measuring component 200 can be determined according to the actual resting position of the second end of the transmission component 300, so as to achieve static contact with the second end of the transmission component 300 at various different resting positions by dynamically adjusting the position of the measuring component 200, thereby enabling effective motion measurement through contact.

[0060] For example, the test end of the measuring element 200 can be moved to a position where it makes static contact with the second end of the transmission element 300, based on the stationary position of the second end of the transmission element 300, and then the measuring element 200 can be fixed to adapt to a variety of different stationary positions.

[0061] Optionally, a second region D2 may also be provided on the fixed stage 100, and the testing system may further include a second fixing member 420, through which the rotating member A is fixed in the second region D2. The fixed stage 100 may also have a second region D2 for fixing the rotating member A. To improve the stability of the rotating member A during testing in the second region D2, the testing system may also include a corresponding second fixing member 420 to fix the rotating member A in the second region D2, effectively reducing adverse effects on testing accuracy such as shaking and displacement of the rotating member A during testing.

[0062] For example, the second fixing member 420 may include fixing parts such as screws, nuts, and clips, which can stably fix the rotating member A in the second region D2.

[0063] It should be noted that the distribution positions of the second region D2 and the first region D1 can be determined based on the contact geometry of the transmission component 300 and the test end. The distribution positions of the first region D1 and the second region D2 can be determined according to the contact geometry of the transmission component 300 and the test end, so that the test end of the measuring component 200 fixed in the first region D1 can properly contact the second end of the transmission component 300 fixed on the rotating component A in the second region D2. This reduces the adverse situation of inability to properly contact the test due to a large distribution distance, and allows for dynamic adjustment during the test, making it suitable for various different test scenarios.

[0064] Optionally, a groove or protrusion of appropriate size and shape can be provided on the fixed platform 100 as a second region D2, depending on the shape and size of the rotating component A. For example, if the rotating component A is a near-cubic structure with a length of 10cm, a width of 5cm, and a height of 2cm, the second region D2 can be set as a groove or protrusion with a width of 6cm, a length of 11cm, and a height of 1cm. This can properly accommodate the rotating component A and reduce the adverse effects on the movement of the transmission component 300 fixed on the top of the rotating component A when the rotating component A is fully inserted into the groove. For example, the rotating component A can be fixed in the second region D2 by screws, nuts, clips, or other structures. After testing, the screws, nuts, clips, or other structures can be removed, and the next rotating component A can be fixed for testing, thereby achieving batch testing of components.

[0065] Optionally, with Figure 2 Taking the illustrated embodiment as an example, the contact geometry may include: a first pointing direction between the first and second ends of the transmission member 300 is perpendicular to a second pointing direction of the test end. The distribution position, size, and other aspects of the two regions can be set and adjusted so that the two pointing directions of the transmission member 300 fixed in the two regions and the measuring member 200 can be perpendicular to each other, achieving normal contact measurement and adapting to various different test scenarios.

[0066] It should be noted that the first end of the transmission component 300 has a fixed shaft 310, and the rotating component A can be provided with a corresponding fixing hole 320. The transmission component 300 can be interference-fitted with the fixing hole 320 on the rotating component A through the fixed shaft 310. The first end of the transmission component 300 is fixed to the rotating component A through the combination of the fixed shaft 310 and the fixing hole 320. Furthermore, in order to reduce adverse situations such as gaps or looseness between the transmission component 300 and the rotating component A, and to improve the effectiveness of the transmission component 300 in driving the rotating component A, the assembly structure between the fixed shaft 310 and the fixing hole 320 can be an interference fit structure. This improves the stability of the transmission component 300 fixed on the rotating component A, reduces the adverse effects of looseness or slippage of the transmission component 300 on the rotating component A on motion measurement, and further improves the accuracy and effectiveness of the measured travel value.

[0067] Optionally, the fixed shaft 310 and the fixed hole 320 can be structures that correspond to each other in size and shape. For example, if the fixed shaft 310 is a round shaft structure with a diameter of 1 cm, the fixed hole 320 can also be a hole structure with a diameter of 1 cm. In order to enable the fixed shaft 310 of the transmission component 300 to enter the fixed hole 320 normally to achieve an interference fit, the rotating component A can be provided with a corresponding elastic structure to form the fixed hole 320. For example, the fixed hole 320 can be formed by an elastic structure such as silicone.

[0068] It should be noted that the transmission component 300 may include a rigid rod-like structure to reduce the adverse effects of deformation of the transmission component 300 on the measured travel value. The measuring component 200 may include various types of numerical indicators, such as digital dial indicators or digital micrometer indicators, and the test end of the measuring component 200 may be the corresponding test end of the numerical indicator.

[0069] It should be noted that the hysteresis detection angle of rotating component A is: θ = arctan(H / L); where θ is the hysteresis detection angle, H is the travel distance measured by the numerical table, and L is the length of the rod-shaped structure. The movement of the first end can be amplified by the second end of the transmission component 300, thereby amplifying the hysteresis present on rotating component A. By amplifying the hysteresis present on rotating component A through the movement of the rigid rod-shaped structure, the hysteresis detection angle corresponding to rotating component A can be calculated based on the measured travel distance and the length of the rod-shaped structure. This effectively improves the accuracy of hysteresis detection for rotating component A, effectively reduces the complexity of the system during testing, and thus reduces the component costs required for testing.

[0070] For example, L can be the length between the first and second ends of the transmission component, and H can be the numerical difference measured by the numerical table during the rotational motion of the transmission component.

[0071] Optionally, please refer to Figure 3 , Figure 3 This is a schematic diagram of another testing system provided in this application embodiment. Considering that during the assembly process of camera equipment, the testing system in the above embodiment can detect backlash, but cannot eliminate or unify backlash. Backlash is related to the assembly of lens components and imaging sensors. When different rotating parts A are adjusted, their rotation angles and positions associated with the focus position are different. It is impossible to preset a uniform angle and position of the rotating parts at the factory. Therefore, when it is put into use, due to backlash and other reasons, the actual focus position of the lens components and / or imaging sensors adjusted by the rotating parts A may be inconsistent. This may result in the lens components and / or imaging sensors adjusted by the rotating parts A requiring a long focusing time when put into use. In order to shorten the time required for the user to focus for the first time after receiving the product, the testing system may also include: a focusing component 510 and a third fixing component 520.

[0072] The focusing assembly 510 and the third fixing member 520 are fixed on the fixing stage 100, and are arranged opposite to each other. The third fixing member 520 is used to fix the lens assembly and / or imaging sensor, and the focusing assembly 510 is used to provide a focused image for the lens assembly and / or imaging sensor. By fixing the lens assembly and / or imaging sensor through the third fixing member 520, the focusing assembly 510 provides the corresponding focused image for the lens assembly and / or imaging sensor. The structure of the focusing assembly 510 and the third fixing member 520 allows for pre-focusing testing of the lens assembly and / or imaging sensor before formal use, effectively reducing the number of events required for focusing during formal use and further optimizing the user experience.

[0073] For example, the lens assembly may include various types or models of lenses, such as an achromatic lens composed of multiple lenses. The imaging sensor may be configured as various types of CMOS (Complementary Metal-Oxide-Semiconductor) sensors, CCD (Charge-Coupled Device) and other devices that can convert light signals into electrical signals to achieve the corresponding imaging function.

[0074] It should be noted that during pre-focusing, a controller connected to the testing system can be set to acquire focused images at multiple focal length positions provided by the lens assembly and / or imaging sensor. The sharpness at these multiple focal length positions is determined through sharpness evaluation. Based on the multiple sharpness values ​​and focal length positions, curves are plotted and fitted to determine the initial focus position corresponding to the lens assembly and / or imaging sensor. This initial focus position is then stored in the memory within the lens assembly and / or imaging sensor. When the lens assembly and / or imaging sensor are put into formal use, the stored initial focus position can be read, and focusing can be performed according to the user's actual needs.

[0075] Optionally, to simulate a corresponding shooting mode, the focusing assembly 510 may include a calibration plate 511 providing an image and a relay lens assembly 512 simulating distance. The calibration plate 511, the relay lens assembly 512, and the third fixing member 520 are fixed on the fixing stage 100. The first position of the calibration plate 511, the second position of the relay lens assembly 512, and the third position of the third fixing member 520 are arranged in a straight line. The calibration plate 511, the relay lens assembly 512, and the third fixing member 520 can be fixed on the fixing stage 100 in sequence, and the fixed positions of the three components are arranged in a straight line to achieve pre-focusing processing of straight distance, effectively improving the success rate of pre-focusing processing and the effectiveness of the focus position.

[0076] For example, the repeater assembly 512 may include one or more installable / removable repeater lenses to provide corresponding focusing services for various types or models of lens assemblies and / or imaging sensors. The calibration plate 511 may be provided with a plate-like structure having shapes such as stripes or dots.

[0077] Optionally, during focusing, an infinitely distant target can be simulated using the optical characteristics of the relay lens assembly 512 and the distance between the calibration plate 511 and the relay lens assembly 512. It should be noted that before testing, the first position of the calibration plate 511, the second position of the relay lens assembly 512, and the third position of the third fixing member 520 can be determined based on the optical characteristics of the lens assembly and / or imaging sensor. The position parameters of the first, second, and third positions are stored in a database. Subsequently, when performing pre-focusing on lens assemblies and / or imaging sensors of the same model, the position parameters can be directly extracted from the database based on the model and other identification information, eliminating the need for multiple position determinations and effectively improving the efficiency and effectiveness of pre-focusing. If the position parameters for the corresponding model cannot be found in the database, or if a fault / problem exists, the first, second, and / or third positions can be adjusted individually or in combination based on the optical characteristics of the lens assembly and / or imaging sensor.

[0078] Optionally, to accommodate the focusing requirements of various lens assemblies and / or imaging sensors of different models and types, a slide rail 530 can be provided on the mounting stage 100. Multiple sliding elements 531 can be provided on the slide rail 530. The calibration plate 511, the relay lens assembly 512, and the third fixing element 520 are slidably fixed on the slide rail 530 via the sliding elements 531. This sliding fixing structure allows for adjustment of the specific positions of the calibration plate 511, the relay lens assembly 512, and the third fixing element 520 on the slide rail 530 according to the specific characteristics of the lens assembly and / or imaging sensor, achieving adjustable pre-focusing and meeting the pre-focusing requirements of various devices.

[0079] For example, the slider 531 can also be configured as a structure with sliding function such as a pulley or a slider. Furthermore, a structure such as a buckle can be added to the pulley or slider to fix the calibration plate 511, the relay mirror assembly 512 and the third fixing member 520 when they slide to the appropriate position.

[0080] Optionally, the testing system may also be equipped with corresponding driving components, which are connected to the calibration plate 511 and the relay lens assembly 512, as well as the lens assembly and / or imaging sensor, respectively, to drive multiple components to move on the slide rail 530. The driving components may include various types of motors, transmission belts, and other components, such as linear motors.

[0081] For example, during the testing process using the testing system, the backlash of the rotating component A can be detected first using the transmission component 300 and the measuring component 200. After determining the backlash of the rotating component A, the focusing component 510, in conjunction with the third fixing component 520 and the slide rail 530, is used to perform pre-focusing processing on the lens assembly and / or the imaging sensor.

[0082] In addition, the components in the various embodiments of this application can be integrated together to form an independent part, or each component can exist independently, or two or more components can be integrated to form an independent part.
