[0002] In modern manufacturing, wire wrapping films are widely used in a variety of industries, including cables, optical fibers, and textiles. The quality of wire wrapping films directly impacts product performance and appearance. The overlap ratio is a key quality indicator for wire wrapping films. However, traditional overlap ratio testing methods typically rely on manual operation and visual observation, which is not only inefficient but also prone to human error. Therefore, the development of an efficient and accurate wire wrapping film overlap ratio tester is of great practical significance and application value.

[0003] Currently, the overlap of wire winding film is generally inspected visually by trained operators in the market. The operators will evaluate the overlap rate according to predetermined quality standards. Although this method is intuitive, it has problems such as strong subjectivity, low efficiency, easy fatigue, and low accuracy. Although some equipment for testing the overlap rate of wire winding film exists, these devices still have many shortcomings in terms of accuracy, efficiency, and ease of use. For example, when adjusting the camera image clarity, the distance between the camera light source and the product is adjusted, ignoring the adjustment between the light source and the product, resulting in unclear images and inaccurate test results.
