Description

Technical Field

[0001] This utility model relates to the field of quality inspection technology, specifically to an AG glass light transmittance testing device. Background Technology

[0002] In numerous fields such as electronic displays, architectural decoration, and automobile manufacturing, AG (Anti-Glare) glass has been widely used due to its advantages in effectively reducing light reflection, minimizing glare interference, and providing a clear visual experience. As market demands for product quality continue to rise, the light transmittance testing of AG glass has become a crucial step in the production process. The accuracy and reliability of the test results directly affect product quality and market competitiveness.

[0003] Currently, devices and equipment for light transmittance testing of AG glass on the market have certain limitations. Traditional testing devices mostly use a single-point light source. When illuminating AG glass, the concentrated light source easily forms light spots on the glass surface, resulting in uneven light intensity distribution. The significant differences in light intensity received by different areas of the AG glass surface make the test results unable to accurately reflect the glass's true light transmittance performance, thus affecting the accuracy of product quality assessment and increasing the risk of substandard products entering the market. Utility Model Content

[0004] The purpose of this invention is to propose an AG glass light transmittance detection device, which can improve the accuracy and efficiency of AG glass detection.

[0005] To achieve the above objectives, this disclosure provides an AG glass light transmittance detection device, including a light box assembly located at the bottom of the device; a detection light source is arranged inside the light box assembly, the detection light source including a plurality of light-emitting diodes, and a plurality of light box columns are also provided inside the light box assembly, each of the light box columns having a flexible support component at its top; a control unit is also included, electrically connected to the detection light source, for controlling the switching and brightness adjustment of the detection light source; and an ambient light sensor is also included, electrically connected to the control unit.

[0006] Beneficial effects of the basic solution: The top of the lightbox column is equipped with flexible support components (such as rubber pads, spring buffer structures, etc.), which can adapt to AG glass of different thicknesses and sizes, avoid hard contact that could cause scratches or stress concentration on the glass surface, and at the same time, the flexible buffer can offset the slight vibrations during the testing process, ensuring the stability of the testing posture.

[0007] The detection light source, composed of several light-emitting diodes, can achieve a large-area, highly uniform surface light source output through array arrangement, avoiding the uneven light spot problem of traditional single-point light sources, ensuring that the light intensity received by each area of ​​the AG glass surface is consistent, and improving the accuracy of AG glass detection.

[0008] The several light box columns inside the light box assembly can strengthen the overall structure and prevent the light source position from shifting due to deformation under stress during long-term use, thus ensuring the long-term stability and reliability of the detection device.

[0009] The control unit can adjust the brightness of the detection light source in real time to adapt to the detection needs of AG glass with different transmittance ranges.

[0010] The ambient light sensor collects real-time light intensity data of the detection area and feeds it back to the control unit, forming a closed-loop control circuit of "light source output - data acquisition - dynamic adjustment". It can automatically compensate for detection errors caused by factors such as light source aging and ambient light interference, improve the consistency of detection results and increase detection efficiency.

[0011] As a feasible preferred solution, the light box assembly adopts a 4040 profile table frame as its basic framework.

[0012] As a feasible preferred embodiment, the light box assembly has several partitions inside to separate the internal space of the light box, and the detection light source is installed on the top of the partitions.

[0013] As a feasible preferred solution, the bottom of the light box assembly is equipped with several foot cups, which are designed to be anti-static and are located at the four corners of the light box assembly.

[0014] As a feasible preferred embodiment, the side of the light box assembly may be provided with ventilation openings or heat dissipation devices.

[0015] As a preferred feasible option, the flexible support component is made of an elastic material and is cylindrical or hemispherical in shape.

[0016] As a feasible preferred solution, the flexible support is fixed by means of snap-fit, adhesive or bolts.

[0017] As a preferred feasible option, the control unit also includes a power supply module for providing a stable power supply to the detection light source and control circuitry.

[0018] As a preferred feasible option, the control unit also includes an operating terminal, which is fixed to the outside of the device or used separately from the device, and the control terminal is equipped with buttons or a touch screen.

[0019] As a feasible preferred embodiment, at least two ambient light sensors are disposed on the top of the light box assembly and are spaced apart. Attached Figure Description

It should be understood that the specific embodiments described herein are only some embodiments of this utility model, and are only used to explain this application, not to limit it. It should be noted that the technical features or combinations of technical features described in the following embodiments should not be considered isolated; they can be combined with each other to achieve better technical effects. The same reference numerals appearing in the accompanying drawings of the following embodiments represent the same features or components, and can be applied to different embodiments.

[0024] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "set" and "connection" should be interpreted broadly. For example, it can be a fixed connection, a detachable connection, or an integrated connection; it can be a mechanical connection (including various forms of mechanical connection, such as couplings or gear pairs), or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, or it can be a connection within two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0025] Furthermore, unless otherwise defined, the technical or scientific terms used in this description shall have the ordinary meaning as understood by one of ordinary skill in the art to which this invention pertains.

[0026] The present invention will now be described in further detail with reference to the accompanying drawings:

[0027] Attached diagram labels: partition 1, detection light source 2, foot cup 3, light box column 4.

[0028] Reference Figures 1 to 3 This embodiment discloses an AG glass light transmittance detection device, including a light box assembly located at the bottom of the device to provide a uniform light source for detection.

[0029] The lightbox assembly preferably uses a 4040 profile table frame as its basic frame. This profile table frame is made of sturdy and durable materials to ensure the stability of the entire lightbox.

[0030] The light box has several partitions inside to divide the internal space, which facilitates wiring and light source installation.

[0031] Several anti-static feet are installed at the bottom of the light box. In this embodiment, there are four feet, which are located at the four corners of the light box assembly. They not only serve to prevent slipping, but also effectively prevent static electricity from affecting the test results.

[0032] The light source, composed of multiple light-emitting diodes (LEDs), is evenly distributed within the light box and specifically mounted on the top of the partition. In this embodiment, two LEDs form a group, with a total of five groups, evenly distributed among the groups. The luminous intensity of each LED is adjustable, and the overall brightness of the light source is precisely controlled by a control unit to ensure uniform and sufficient illumination in the detection area. The luminous surface of the light source faces upward, directly illuminating the AG glass placed on the detection platform, providing a uniform and stable light source for transmittance detection.

[0033] The light box is also equipped with several light box columns. In this embodiment, there are 24 columns, which are evenly distributed around the light box to provide support and reinforcement.

[0034] In one embodiment, ventilation openings or heat dissipation devices may be provided on the side of the light box as needed to ensure a suitable internal temperature and extend the lifespan of the lamp tubes.

[0035] Each lightbox column is equipped with a flexible support component at its top to support the AG glass to be inspected. The flexible support is made of elastic material, such as silicone or rubber, and is cylindrical or hemispherical in shape, with its height adjustable according to the thickness of the AG glass. The flexible support is secured by clips, adhesives, or bolts, ensuring stability and reliability during inspection while also facilitating disassembly or replacement.

[0036] The flexible support components are customized according to the size and shape of the AG glass to ensure that the glass remains stable and undamaged during testing. Multiple support points are evenly distributed to effectively distribute the weight of the glass and prevent excessive local pressure that could cause it to break.

[0037] Example 2

[0038] The control unit includes a power module, a control circuit, and an operating terminal. The power module provides a stable power supply to the detection light source and the control circuit, while the control circuit controls the switching on and off of the detection light source, brightness adjustment, and the automation of the detection process. The operating terminal is located externally to the device for easy operation and setup by personnel. The operating terminal can be fixed externally to the device or used separately.

[0039] The control unit is connected to the detection light source via wires that pass through the bottom of the detection platform and connect to each LED of the light source. Operators can set parameters such as the brightness, on / off time, and detection mode of the detection light source using buttons or a touchscreen on the operating terminal. The control unit also has a data interface, enabling it to transmit detection results to external devices for recording and analysis.

[0040] It also includes at least two ambient light sensors, which are installed on the top and / or side of the light box assembly. The ambient light sensors are electrically connected to the control unit and can detect the ambient brightness. The control circuit generates a control signal based on the actual ambient brightness to automatically control the brightness of the detection light source. For example, if the ambient brightness is too bright, the control circuit will control the detection light source to increase its brightness so that the light source meets the detection conditions.

[0041] Ambient light sensors can also address errors caused by glass transmittance. Low-transmittance glass may cause the ambient light sensor to detect reduced ambient light, leading the control circuit to lower the brightness of the detection light source. However, low-transmittance glass requires higher brightness for detection. This technical solution uses at least two ambient light sensors that maintain a distance from each other. Since the glass placed on this detection device needs to be moved, if the glass transmittance is low, a difference in transmittance will occur between the ambient light sensors during placement. The control circuit can use this difference to match the transmittance, thereby compensating for the brightness of the detection light source and solving this technical problem.

[0042] Instructions for using the device:

[0043] When conducting light transmittance testing on AG glass, the glass to be tested is first placed on a flexible support assembly to ensure its stability and prevent damage. Then, the testing light source within the lightbox assembly is turned on, allowing light to evenly illuminate the glass surface. The light transmittance of the glass is observed through the testing platform, relevant data is recorded, and analysis is performed.
