Description

Technical Field

[0001] The present invention relates to the technical field related to matte film thickness detection, and in particular to a matte film thickness detector and a detection method. Background Art

[0002] The background technology of matte film thickness testers mainly stems from the widespread application of thin film materials in modern industry and the need for accurate thickness measurement. With the rapid development of science and technology, the application of thin film materials in semiconductors, optoelectronics, packaging, materials science and other fields is becoming increasingly widespread. The accurate measurement of their thickness has become an important part of ensuring product quality and optimizing material performance. The existing thickness detection device has certain deficiencies in its operation. During the operation of the film detection device, some other problems are still exposed. Due to the static electricity, the surface of the matte film easily absorbs dust in the air, which makes it easy to have deviations in the subsequent detection process, thereby affecting the accuracy of the test results. In order to solve the above-mentioned defects, a LCP film thickness detection device disclosed in the prior art (application number CN202010916146.6, publication date 2020-12-18 Chinese patent) can be referred to. After the detection device is driven to rotate by the driving motor through the flattening component, first, the abnormal protrusions on the LC suction pipe (26) film are trimmed and flattened by the flattening member, which can facilitate the purpose of subsequent detection; In addition, reference may be made to a BOPP film thickness detection device disclosed in the prior art (Chinese patent application number CN202410067282.0, published on August 20, 2024). This detection device is provided with a mounting frame and a leveling roller. During the detection process of the detection rod, the two leveling rollers can rotate in opposite directions on the surface of the BOPP film to level the surface of the BOPP film, making the surface of the BOPP film smoother during detection, thereby increasing the accuracy of the detection data. Finally, reference may be made to a device for detecting the thickness of a mobile phone protective film disclosed in the prior art (Chinese patent application number CN202210569051.0, published on June 24, 2022). The device rotates in coordination with a first rotating plate and a second rotating plate, so that the entire device can detect the thickness of the protective film while clamping the protective film. Although the above operation can smooth the film, some other problems are still exposed during the actual operation process. Due to the static electricity, the surface of the matte film is very easy to absorb dust in the air, which makes it easy to deviate in the subsequent detection link, thereby affecting the accuracy of the test results.
