Description

Technical Field

[0001] This utility model relates to the field of flash testers, specifically to the testing mechanism of a dual-lens one-button rapid flash tester. Background Technology

[0002] A flash measurement instrument is a high-precision non-contact measuring device based on optical imaging and high-speed image processing technology. It has a wide range of applications, including but not limited to industrial manufacturing, precision machining, electronic component inspection, and biomedicine. Its core function is to rapidly measure dimensions, geometric tolerances, and surface defects by instantly capturing two-dimensional or three-dimensional images of the object being measured and combining this with algorithmic analysis.

[0003] As intelligent manufacturing demands ever higher efficiency and accuracy in testing, flash detectors are gradually evolving towards higher speeds, multi-view capabilities, and greater adaptability. Especially in measurement scenarios involving complex curved surfaces, minute structures, and dynamic targets, dual-lens or multi-lens collaborative imaging technology has become a key means to improve measurement coverage and data integrity. Existing flash detector testing mechanisms typically consist of an optical imaging module, a mechanical positioning platform, a light source system, and a data processing unit.

[0004] However, existing dual-lens flash testers still have certain shortcomings. Traditional dual lenses are fixed by independent brackets, requiring repeated manual assembly, resulting in low assembly efficiency and low positioning accuracy, which in turn affects assembly efficiency and measurement repeatability. Furthermore, the inconvenience of assembling and aligning existing lenses leads to extended production cycles, and subsequent maintenance requires complete disassembly and calibration, making it difficult to meet the rapid insertion and replacement requirements of testing scenarios. Therefore, there is an urgent need for a flash tester mechanism that can achieve high-precision collaborative positioning and rapid assembly of dual lenses, improving the stability and production efficiency of the measurement system. Utility Model Content

[0005] The purpose of this invention is to address the above-mentioned deficiencies and provide a testing mechanism for a dual-lens one-button rapid flash tester, thereby solving the technical problem in the background art of how to improve the rapid positioning and assembly of dual lenses to improve the assembly efficiency and positioning accuracy of lens installation.

[0006] The objective of this utility model is achieved through the following means:

[0007] The testing mechanism of the dual-lens one-button rapid flash tester includes a lifting drive component and a test assembly mounted on the lifting drive component. The lifting drive component is connected to the test assembly via a lifting plate. The lifting drive component can drive the lifting plate to raise or lower the test assembly. The test assembly includes a mounting plate, a first camera lens, a second camera lens, and a mounting base. A connecting plate is mounted on the bottom of the lifting plate. One side of the mounting plate is paired with the connecting plate, and a mounting hole for mounting the first camera lens is formed between the mounting plate and the connecting plate. The sides of the mounting plate and the connecting plate are provided with insertion slots for quick insertion. The side of the mounting base is provided with insertion protrusions that are paired with the insertion slots for insertion, so that the mounting base and the mounting plate can be detachably installed. A pressure block is connected to the outside of the mounting base, and a connecting hole for mounting the second camera lens is formed between the mounting base and the pressure block.

[0008] The rigid connection structure between the lifting drive component and the lifting plate enables precise lifting control of the test components, ensuring that the test components maintain high-precision collaborative positioning during the lifting process, thereby improving assembly positioning accuracy and measurement repeatability.

[0009] Furthermore, as described above, the lifting drive component includes a support plate, a sliding member, a lead screw, and a drive motor. The sliding member is mounted on the side of the support plate, and a sliding seat that can reciprocate along the sliding member is connected to the sliding member. The lead screw is connected to the sliding seat through a nut, and one end of the lead screw is coaxially connected to the output shaft of the drive motor through a coupling, so that the drive motor can drive the lead screw to move the sliding seat reciprocally.

[0010] The use of a lead screw-sliding seat transmission structure in conjunction with a drive motor enables precise control of the lifting stroke of the lifting plate. The sliding fit design between the sliding component and the support plate enhances lifting stability, reduces swaying and offset during assembly, and improves the stability of the measurement system.

[0011] Furthermore, as described above, the lifting plate is connected to the sliding seat, so that the reciprocating movement of the sliding seat can drive the lifting plate to rise or fall synchronously. One end of the connecting plate is paired with the lifting plate, so that the connecting plate and the lifting plate are installed in an "L" shape.

[0012] The connecting plate and the lifting plate are installed in an "L" shape to form a stable support structure. The rigid connection ensures that the test components always move accurately in the vertical direction during the lifting process, avoiding measurement deviations caused by loose lens assembly.

[0013] Furthermore, as described above, the connecting plate has a connecting opening on its side near the mounting plate, and the mounting plate has an installation opening on its side near the connecting plate, so that the connecting opening and the installation opening are paired to form an installation hole for mounting the first camera lens. The connecting plate and the mounting plate also have fixing holes for fixing the first camera lens.

[0014] The mounting hole structure formed by the matching of the connecting opening and the mounting opening, together with the fixing hole design, enables the rapid insertion and precise positioning of the first camera lens, solving the problems of low assembly efficiency and low positioning accuracy of traditional mechanisms. At the same time, the fixing hole ensures that the lens is installed firmly, reducing measurement errors caused by vibration.

[0015] Specifically, the first camera lens can be pre-installed with the mounting plate, and the mounting plate can be paired with the connecting plate, thereby quickly completing the positioning and installation of the first camera lens.

[0016] Furthermore, as described above, one end of the insertion slot extends outward for conduction, and the other end of the insertion slot forms a limiting part, so that the side of the mounting base slides into the opening end of the insertion slot through the insertion protrusion and mates with the limiting part. The side of the mounting base forms a mounting groove for mates with the second camera lens, and the side of the pressure block is provided with a pressure groove that mates with the mounting groove, so that a connecting hole for mounting the second camera lens can be formed between the mounting groove and the pressure groove.

[0017] The sliding insertion design with insertion slots and protrusions, combined with the limiting part, enables quick and detachable connection between the mounting base and the mounting plate. This solves the problems of inconvenient lens assembly and the need for complete disassembly for maintenance in traditional mechanisms, meeting the needs of quick insertion and replacement of the second camera lens in testing scenarios and improving assembly, maintenance and replacement efficiency.

[0018] Furthermore, as described above, the side of the pressure block is connected to the mounting base via a locking member, so that the pressure groove matches the mounting groove, and the pressure groove can be used to press the second camera lens.

[0019] The pressure block connects to the mounting base through a locking component to form a connection hole. The pressure groove and the mounting groove cooperate to press the second camera lens, ensuring the stable installation of the second camera lens and ensuring that the second camera lens remains stable during the test, thereby improving the stability of the measurement system and the assembly positioning accuracy.

[0020] Furthermore, as described above, the mounting base has a mounting section on its side, and the mounting section has a through hole, allowing the mounting section to be connected to the mounting plate by a limiting member passing through the through hole.

[0021] The mounting section is connected to the mounting plate through a limiting component, which enhances the structural stability of the mounting base and solves the problem of decreased measurement accuracy caused by structural loosening after long-term use of traditional mechanisms. This ensures that the second camera lens maintains high-precision positioning even in high-frequency use scenarios, thereby improving the long-term stability of the measurement system.

[0022] Furthermore, as described above, the first camera lens is composed of a low-magnification telecentric lens, and the second camera lens is composed of a high-magnification telecentric lens.

[0023] By adopting a combination of low-magnification and high-magnification telecentric lenses, the problem of insufficient adaptability to measurement scenarios in traditional dual-lens flash meters is solved. Through the coordinated work of lenses with different magnifications, accurate measurement from macroscopic to microscopic is achieved, improving the scene adaptability and measurement accuracy of the measurement system.

[0024] Specifically, the low-magnification telecentric lens enables large-scale, fast photographic measurement, while the high-magnification telecentric lens allows for high-precision measurement of minute dimensions, enabling the instrument to complete measurements quickly and efficiently.

[0025] The beneficial effects of this utility model are as follows: By matching the insertion slot on the side of the mounting plate with the insertion protrusion on the side of the mounting base, the mounting base and the mounting plate can be detachably installed, reducing the positioning error of assembly alignment, improving the assembly efficiency and positioning accuracy of dual lenses, and meeting the needs of rapid insertion and replacement in testing scenarios. The mounting plate and the connecting plate form a mounting hole for the first camera lens to be installed, ensuring that the first camera lens is accurately positioned and operates stably, reducing the measurement repeatability accuracy deviation caused by loose assembly. This structure, through the cooperation of the pressure block and the mounting base, enables the rapid insertion and convenient disassembly of the second camera lens, simplifies the assembly process, avoids the maintenance needs of overall disassembly and calibration, and improves the efficiency of later maintenance.

[0026] The mounting base and mounting plate can be quickly assembled and disassembled through the insertion slot and the insertion protrusion. The connection hole structure formed by the mounting base and the pressure block allows the dual lenses to be disassembled and replaced or calibrated separately during later maintenance, without the need to disassemble the entire test mechanism, thus shortening maintenance time and improving testing efficiency.
