Description
Technical Field
[0001] This utility model relates to the field of glass plane mirror technology, and in particular to an attitude adjustment device for detecting glass plane mirrors. Background Technology
[0002] As a key optical component in a HUD system, the performance of the glass flat-panel HUD reflector directly affects the system's imaging quality, display clarity, and stability. Currently, there is still room for improvement in the reflectivity, flatness, and temperature resistance of glass flat-panel HUD reflectors on the market. Some products have insufficient reflectivity, resulting in insufficient display brightness and difficulty in clear display under strong light; significant flatness deviations can easily cause image distortion; and poor temperature resistance in high-temperature environments such as automotive engine compartments affects their lifespan.
[0003] This study investigates the temperature resistance and stability of glass planar HUD reflectors. Through modification of the glass substrate and optimization of the coating process, its performance stability and lifespan under harsh environments such as high temperatures and humidity are improved. After coating, the glass substrate is placed in an environmental simulation chamber for high and low temperature testing within a range of -45℃ to 80℃. Following testing, a visual inspection is conducted to check for cracks, fractures, surface defects, and film layer cracking. Then, professional instruments such as interferometers and polarizers are used to measure optical performance parameters to determine the temperature resistance of the optical glass.
[0004] Visual inspection, as a preliminary screening step, is conducted using a CCD vision inspection system. The heat-resistant glass lens is placed flat on the inspection table; it cannot be held by hand. The CCD camera faces the inspection table, captures an image of the glass lens, and transmits it in real-time to a monitor. The monitor displays a magnified image of the glass lens, which is then visually examined for surface defects. The glass lens needs to be manually adjusted on the inspection table to ensure complete image capture. However, the glass lens is mostly horizontally movable and difficult to change its orientation at multiple angles, making it difficult to observe the surface condition from multiple perspectives and hindering comprehensive inspection. If the lens needs to be angled, the operator must hold it and change its posture, which inevitably obstructs some view of the glass. Summary of the Invention
[0005] To address the problem of difficulty in adjusting glass lenses at multiple angles on a testing table, this invention provides a posture adjustment device for testing glass plane mirrors. The glass lens is held horizontally by a clamp that can be tilted arbitrarily, thereby flexibly changing the posture of the glass lens. After tilting, it can self-reset to ensure the glass lens remains horizontal.
[0006] To achieve the above objectives, the technical solution adopted by this utility model is as follows:
[0007] An attitude adjustment device for detecting glass plane mirrors includes a base, a clamping frame, a compression spring, and clamps. The clamping frame is arranged on the upper part of the base, and a universal connector is provided between the base and the clamping frame to drive the clamping frame to swing in multiple directions and rotate horizontally relative to the base. The compression spring is also provided between the clamping frame and the base to keep the clamping frame and the base parallel vertically. The clamps are symmetrically arranged on both sides of the clamping frame, and the ends of the clamps are fitted with chucks. The chucks are rotatably connected to the clamps, and the chucks on the two clamps cooperate to clamp the glass mirror.
[0008] Furthermore, the base includes a chassis and a base rod, with the base rod positioned at the center of the chassis. The base rods are arranged vertically, and the cross-section of the chassis and base rods after connection and assembly is an inverted "T" shape.
[0009] The clamping frame includes a top plate and a top rod. The top rod is located at the center of the top plate and is arranged vertically. After the top plate and the top rod are connected and combined, the cross-section is "T" shaped.
[0010] Furthermore, the universal joint is arranged between the bottom rod and the top rod, and the compression spring is sleeved on the outside of the universal joint.
[0011] Furthermore, the universal connector includes a hemispherical groove and a swing ball. The hemispherical groove is fixedly connected to the base downwards, and the swing ball is movably arranged inside the hemispherical groove to facilitate the swing of the swing ball. The upper part of the swing ball protrudes from the hemispherical groove, and the swing ball is fixedly connected to the clamping frame upwards, so that the clamping frame can swing along with the swing ball.
[0012] Furthermore, the hemispherical groove is a hemispherical groove made of elastic steel plate. Multiple slots are provided circumferentially on the upper part of the hemispherical groove. Each slot is slit-shaped, and the multiple slots divide the upper part of the hemispherical groove into multiple elastic segments. These elastic segments cooperate to clamp the swinging sphere, preventing the swinging sphere from easily detaching from the hemispherical groove.
[0013] Furthermore, each of the elastic segments is provided with a stepped arc plate, and the stepped arc plates on multiple elastic segments are arranged in a circle. The bottom of the clamping frame is provided with a stepped top ring, the diameter of which is smaller than the diameter of the circle formed by the multiple stepped arc plates. A compression spring is arranged between the stepped top ring and the stepped arc plate. The compression spring is a pagoda-shaped spring and is arranged around the swinging sphere.
[0014] Furthermore, the clamp includes a vertical plate and a hand-tightening bolt, the hand-tightening bolt being arranged horizontally on the vertical plate, the hand-tightening bolt passing through the vertical plate laterally and being threadedly connected to the vertical plate.
[0015] Furthermore, a clamp is fitted onto one end of the hand-tightening bolt. The clamp includes a circular sleeve section and a retaining section. The circular sleeve section is fitted onto the end of the hand-tightening bolt and is interchanged with the hand-tightening bolt. The retaining section is provided at one end of the circular sleeve section. A V-shaped groove is formed on the retaining section, and the edge of the glass lens is placed in the V-shaped groove.
[0016] A rotating ring is provided on the outside of the chuck to control the rotation of the chuck.
[0017] The beneficial effects of this utility model through the above technical solution are:
[0018] This utility model has a reasonable structural design. The clamping frame and the base are connected by a universal connector, and the glass lens to be tested is mounted on the clamping frame. In this way, the clamping frame can swing in any direction relative to the base, which can drive the glass lens to swing. After swinging, the elastic force of the compression spring keeps the clamping frame horizontal. The clamping frame can also rotate horizontally relative to the base, which facilitates the rotation of the glass lens.
[0019] The clamping device of this invention uses two clamps to hold the glass lens to be tested. The clamps contact the edge of the glass lens through the chuck, which can hold the glass lens and rotate relative to the clamp. Therefore, the glass lens can rotate and adjust its angle, allowing for flexible adjustment of its orientation from multiple directions. This provides a more comprehensive view of the CCD camera's image, enabling a complete observation of the glass lens surface for any defects. Attached Figure Description

[0026] The specific embodiments of this utility model are described in detail below with reference to the accompanying drawings:
[0027] like Figures 1-5 As shown, an attitude adjustment device for inspecting a glass plane mirror 15 is disclosed. This device enables horizontal rotation and arbitrary swaying of the glass mirror 15, thereby flexibly changing the angle of the glass mirror 15. Combined with a CCD vision inspection system, it allows for multi-directional and multi-angle observation of the glass mirror 15, enabling a comprehensive visual inspection of the surface of the glass mirror 15 for defects.
[0028] The attitude adjustment device includes a base 1, a clamping frame 2, a compression spring 3, and a clamp 4. The base 1 is the foundation of the entire attitude adjustment device. The base 1 includes a chassis 101 and a base rod 102. The chassis 101 is disc-shaped, with the base rod 102 positioned at its center. The base rod 102 is cylindrical and vertically arranged. When the chassis 101 and base rod 102 are connected and combined, their cross-section forms an inverted "T" shape. The clamping frame 2 is arranged on the upper part of the base 1. The structure of the clamping frame 2 is similar to that of the base 1. Here, the clamping frame 2 includes a top plate 201 and a top rod 202. The top rod 202 is positioned at the center of the top plate 201 and vertically arranged. When the top plate 201 and top rod 202 are connected and combined, their cross-section forms a "T" shape.
[0029] The base 1 and the clamping frame 2 are two independent components. To connect them, a universal connector 5 is provided between the base 1 and the clamping frame 2. Specifically, the universal connector 5 is arranged between the bottom rod 102 and the top rod 202. The universal connector 5 drives the clamping frame 2 to swing in multiple directions and rotate horizontally relative to the base 1. That is, under the action of the universal connector 5, the clamping frame 2 can rotate horizontally and swing in multiple directions.
[0030] In this embodiment, the universal connector 5 includes a hemispherical groove 501 and a swing ball 502. The hemispherical groove 501 is fixedly connected to the bottom rod 102 of the base 1. The hemispherical groove 501 is a hemispherical groove made of elastic steel plate. It is formed by stamping a thin steel plate with a certain elasticity. The structure of the hemispherical groove 501 is similar to a round bowl.
[0031] A swing ball 502 is movably disposed within a hemispherical groove 501, allowing it to swing freely within the groove. The upper part of the swing ball 502 protrudes beyond the hemispherical groove 501, with the upper surface of the groove 501 higher than the center of the swing ball 502. The swing ball 502 is connected and fixed upwards to the clamping frame 2, allowing the clamping frame 2 to also swing freely with the swing ball 502.
[0032] To facilitate the installation of the oscillating ball 502, six slots 6 are circumferentially arranged on the upper part of the hemispherical groove 501. Each slot 6 is slit-shaped, dividing the upper part of the hemispherical groove 501 into six elastic segments 7. The upper end of each elastic segment 7 is higher than the center of the oscillating ball 502. When installing the oscillating ball 502, it is inserted into the hemispherical groove 501. Upon insertion, the elastic segments 7 deform and expand outward until the oscillating ball 502 is fully inserted into the hemispherical groove 501. Then, the elastic segments 7 return to their original position and contract inward. After resetting, the six elastic segments 7 cooperate to hold the oscillating ball 502, ensuring that it does not easily detach from the hemispherical groove 501, and without affecting its flexible oscillation within the hemispherical groove 501.
[0033] After the oscillating ball 502 oscillates within the hemispherical groove 501, a compression spring 3 is provided between the clamping frame 2 and the base 1 to achieve the reset of the oscillating ball 502. The compression spring 3 is sleeved outside the universal connector 5 and is a pagoda-shaped spring. Under the elastic action of the compression spring 3, the oscillating ball 502 can be reset. After reset, it can make the clamping frame 2 and the base 1 remain parallel vertically.
[0034] During installation, each elastic segment 7 is provided with a stepped arc plate 8, which is spaced apart from the upper surface of the elastic segment 7. The stepped arc plates 8 on the six elastic segments 7 are arranged in a circle. At the same time, a stepped top ring 9 is provided on the top rod 202 at the bottom of the clamping frame 2. The diameter of the stepped top ring 9 is smaller than the diameter of the circle formed by the six stepped arc plates 8. A compression spring 3 is arranged between the stepped top ring 9 and the stepped arc plate 8. The compression spring 3 surrounds the swing ball 502, and the upper end of the compression spring 3 can be fixedly connected to the stepped top ring 9.
[0035] In this way, after the manually controlled oscillating ball 502 swings to one side, the compression spring 3 is compressed accordingly. After the manual control is removed, the elastic force of the compression spring 3 causes the oscillating ball 502 to return to its original position. It should be noted that the elastic force of the compression spring 3 is greater than the frictional force between the hemispherical groove 501 and the oscillating ball 502.
[0036] Clamps 4 are symmetrically arranged on both sides of the clamping frame 2. Each clamp 4 includes a vertical plate 401 and a hand-tightening bolt 402. The vertical plate 401 is fixedly connected to the top plate 201 of the clamping frame 2. The hand-tightening bolt 402 is horizontally arranged on the vertical plate 401, and it passes through the vertical plate 401 laterally and is threadedly connected to the vertical plate 401. The hand-tightening bolt 402 can be screwed onto the vertical plate 401.
[0037] The clamp 4 is also fitted with a chuck 10 at one end, which is rotatably connected to the clamp 4. The chucks 10 on both sides of the clamp 4 cooperate to hold the glass lens 15. That is, the chuck 10 is fitted at one end of the hand-tightening bolt 402. The chuck 10 includes a circular sleeve section 11 and a retaining section 12. The circular sleeve section 11 is fitted at the end of the hand-tightening bolt 402 and is rotatably connected to the hand-tightening bolt 402. The retaining section 12 is fixedly installed at one end of the circular sleeve section 11. A V-groove 13 is opened on the retaining section 12, and the edge of the glass lens 15 is placed in the V-groove 13.
[0038] A rotating ring 14 is provided on the outside of the chuck 10, which is used to control the rotation of the chuck 10. The rotating ring 14 includes a circular ring and support rods. At least three support rods are provided on the inner side of the circular ring in a circumferential direction. The two ends of the support rods are respectively connected and fixed to the inner side of the circular ring and the outer wall of the circular sleeve section 11. Thus, the rotating ring 14 and the circular sleeve section 11 are connected and fixed, and the rotation of the entire chuck 10 can be easily controlled by operating the rotating ring 14.
[0039] The principle of this utility model is as follows: First, the base 1 is fixed on the inspection table of the CCD vision inspection system.
[0040] Then, the glass lens 15, after undergoing temperature resistance testing, is installed on the clamping frame 2. During installation, one edge of the glass lens 15 is first placed against the chuck 10 of one clamp 4, and then the hand-tightening bolt 402 of the other clamp 4 is tightened until the chuck 10 on the hand-tightening bolt 402 is against the opposite edge of the glass lens 15. At this time, the two clamps 4 cooperate to clamp the glass lens 15, but care should be taken not to overtighten the hand-tightening bolt 402, firstly to avoid increasing the clamping force on the glass lens 15, and secondly to ensure that the chuck 10 can rotate relative to the hand-tightening bolt 402.
[0041] After clamp 4 holds the glass lens 15, the clamping frame 2 is manually operated to rotate it horizontally, causing the glass lens 15 to remain exposed to the CCD camera's view, allowing observation of the surface condition of the glass lens 15 based on the magnified image on the monitor. During this process, the clamping frame 2 can be manually operated to swing it, causing the glass lens 15 to tilt at an angle, allowing observation of the surface condition of the glass lens 15 after the tilt. After the clamping frame 2 is no longer operated, the compression spring 3 causes the clamping frame 2 to return to its original position, remaining parallel to the base 1.
[0042] During the process, while wearing gloves, the edge of the glass lens 15 can be manually rotated. This rotation is centered on the hand-tightening bolt 402, causing the two clamps 10 to rotate synchronously, thereby changing the tilt angle of the glass lens 15 and observing the condition of the tilted glass surface. This allows for flexible adjustment of the angle and orientation of the glass lens 15, and multi-angle imaging of the glass lens 15 via a CCD camera, enabling better manual observation and achieving a comprehensive inspection of the glass lens 15 for any defects.
[0043] The embodiments described above are merely preferred embodiments of this utility model and are not intended to limit the scope of implementation of this utility model. Therefore, all equivalent changes or modifications made to the structure, features and principles described in the patent claims of this utility model should be included within the scope of the patent application of this utility model.
