[0002] In the manufacturing industry of optical films, the control of finished product quality is a key link to ensure the performance and reliability of products. As a key material widely used in optoelectronic products such as touch screens and displays, the surface quality of OCA films directly affects the display effect and service life of the final products. Therefore, it is particularly important to conduct strict and efficient defect detection on OCA film finished products. However, in current production practices, the defect detection process of OCA film finished products generally relies on manual visual inspection, that is, operators directly observe the film surface with the naked eye without any tools to identify defects such as scratches, bubbles, foreign objects, and uneven coating. Over time, it is easy to cause eye discomfort. Content of the Utility Model

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0017] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments in the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0018] Please refer to Figures 1-4, the present utility model provides a technical solution: an adjustable magnifying glass OCA detection device, which is composed of a base 1, a bracket 2, a light source 3, a diffusion plate 4, and a product fixture 5. Among them, the bracket 2 and the light source 3 are both installed on the upper part of the base 1, the diffusion plate 4, the product fixture 5, and the magnifying module 6 are all installed outside the bracket 2, and the light source 3, the diffusion plate 4, the product fixture 5, and the magnifying module 6 are arranged in sequence from bottom to top.
