Problems solved by technology
[0003] In addition to the above-mentioned defects such as scratches and color blocks that will affect the optical properties of the light-transmitting film, whether the film thickness of the light-transmitting film is consistent will also affect the optical effect of the light-transmitting film
However, generally speaking, due to the large volume of the light-transmitting film after production, the timing for film thickness detection of the light-transmitting film is usually after the light-transmitting film is to be processed and cut into a predetermined size. This method is not only time-consuming and labor-intensive, but also often leads to detection errors.
In addition, when the film thickness of the cut light-transmitting film is found to be abnormal, the entire cut light-transmitting film can only be scrapped, which will easily lead to waste of raw materials, or cut it into pieces. Light-transmitting film with a smaller area, but the light-transmitting film after re-cutting may be too small or out of shape
Therefore, it can be seen from the above description that the existing method for detecting film thickness is still not perfect, and there is still room for improvement

Embodiment Construction
[0019] Please refer to figure 1 As shown, the detection system of the preferred embodiment of the present invention is used to detect whether the film thickness of a light-transmitting film 100 is abnormal, and includes a driving device 10, a reference member 20, a camera device 30, a processor 40 and a mark device 50. in:
[0020] The driving device 10 is connected with the transparent film 100 to drive the transparent film 100 to move along an action path. In this embodiment, the driving device 10 is a rolling drum, which is used to roll the finished light-transmitting film 100 into a bundle, and drive the light-transmitting film 100 to move while rolling.
[0021] The reference member 20 is located below the action path of the transparent film 100, and in this embodiment, the reference member 20 is a strip-shaped light source, and its light-emitting surface forms a detection surface 22, and the detection surface 22 is provided with A plurality of detection lines 24 are a...

A light-transmitting film detection system and a detection method thereof are provided. The detection system is used for detecting whether the thickness of a light-transmitting film is abnormal, and comprises a benchmark, a drive device, a camera device and a processor. The benchmark is disposed on one side of the light-transmitting film, and has a detection surface which faces the light-transmitting film and is provided with multiple spaced detection lines. The drive device drives the light-transmitting film to move relative to the benchmark. The camera device is disposed on the other side of the light-transmitting film, faces the light-transmitting film and the benchmark, and continuously shoots an image with spaced lines displayed by the benchmark through the light-transmitting film when the light-transmitting film is driven by the drive device to move. The processor is electrically connected with the camera device, and compares the lines to judge whether the image is distorted so as to judge whether the thickness of the light-transmitting film is abnormal.
Description
technical field [0001] The invention relates to a detection device; in particular, it refers to a detection system and a detection method of a transparent film. Background technique [0002] With the advancement of the optical industry, the application of light-transmitting films has become increasingly popular in the electronics industry (such as the inner layer of touch panels) and the automotive industry (such as thermal insulation paper). For the convenience of transportation, after the production of the light-transmitting film is completed, it is usually bundled on a long tube, and the surface of the light-transmitting film is inspected for scratches, color blocks, etc. Circle and mark the defective parts of the light-transmitting film to prevent users of the light-transmitting film (such as manufacturers of touch panels and thermal insulation paper) from misusing the defective light-transmitting film to ensure that the light-transmitting film can be used time quality....
