Description

Technical Field

[0001] The invention relates to the technical field of light transmittance detection of glass cover plates, and in particular to a glass cover plate decomposition optical positioning component and a decomposition positioning method thereof. Background Art

[0002] In the production and application of glass, different types of glass have different light transmittance, resulting in different application scenarios. For example, curtain walls need to transmit white light to enhance lighting, while absorbing or refracting other colors of light to avoid glare. For experimental equipment that requires special lighting, special glass cover plates are usually used to select the light source.

[0003] When existing manufacturers produce glass cover plates, they need to test the light transmittance of specially produced glass cover plates. Traditional testing methods mostly use natural light to observe the transmitted light.

[0004] However, in the actual production process, the glass cover is only required to absorb a single light source, and other colors of light sources do not need to be absorbed, which results in the transmitted light being of mixed colors and difficult to clearly identify. Therefore, a prism is needed to decompose the transmitted light to achieve clear observation. During the detection process, due to differences in light transmittance and refraction angle, the back panel carrying the decomposed light needs to be adjusted in position to clearly present the decomposed light.

[0039] The detection device is installed through the detection platform 1, and the fixed light shielding tube 10 is used to protect the light after light transmission, so as to avoid the influence of ambient light on the detection.

[0040] The telescopic adjustment component includes a threaded end tube 27, multiple groups of linearly distributed adjustment end plates 17 and a base plate 15. The threaded end tube 27 is fixed on one side of the decomposition frame 5.

Adjacent adjustment end plates 17 are connected by folding shading tubes 30. The inner diameters of the multiple groups of folding shading tubes 30 are increased in steps, and a telescopic component with adjustable lateral distance is arranged between adjacent adjustment end plates 17. A back plate 26 for receiving the decomposed light is arranged on the inner side of the base plate 15, and a positioning rod 16 is arranged on the outer side of the base plate 15 and is laterally slidably inserted into the side frame 6.
