Description

Technical Field

[0001] The utility model relates to the field of detection devices, in particular to a light transmittance detection device for optical glue. Background Art

[0002] Optical glue, also known as glue for bonding optical parts, is a polymer material with optical properties similar to those of optical parts and excellent bonding properties. Optical glue is widely used in the fields of optical instruments, touch screens, displays, aerospace or military optical devices, etc. For example, in touch screens, optical glue is mainly used for material bonding to achieve the effect of capacitive touch sensing; in display assembly, optical glue is used to bond various optical components together to form a complete optical assembly, which can glue these components into an optical assembly that meets the requirements of optical path design, or be used for gluing the glass of high-precision optical scales, filters and other devices for protection.

[0003] The light transmittance of optical glue is one of its important performance indicators. Especially during the gluing process of optical components, high light transmittance can ensure that the performance of optical components is not affected. Generally speaking, the light transmittance requirement of optical glue is above 90%. For some high-performance optical glues such as OCA (Optical Clear Adhesive) optical glue, the full light transmittance can even reach more than 99%. As an optical-grade high-transparency substrate-free double-sided adhesive, OCA optical glue has the characteristics of high clarity, strong light transmittance (full light transmittance > 99%), high adhesion, water and heat resistance, ultraviolet resistance, good bonding strength and small curing shrinkage. Its high light transmittance characteristic enables the touch screen to reduce the reflection loss of light during display, improve the contrast of the image, and at the same time can eliminate the influence of dust and moisture, providing a better display effect.

[0004] For the optical glue light transmittance detection device, limit plates are provided on the front and back sides of the workbench. Through the limit plates, the light glue can be stacked neatly in one direction before entering the workbench. During the use of the existing optical glue light transmittance detection device, the distance between the two limit plates is equal to the width of the light glue. When detecting products with different sizes, it is often necessary to manually adjust the distance between the two limit plates, which is not convenient to use. Summary of the Utility Model
