In the field of electronic device manufacturing, silicone silk screen buttons are widely used in various electronic products due to their good touch, durability, and aesthetics. Character accuracy is crucial for silicone silk screen buttons, as it not only affects the appearance and brand image of the product, but also relates to the user experience. For example, blurry or offset characters may lead to user errors and reduce the usability of the product. The following will comprehensively introduce the detection method, process, and key points of the accuracy of silicone silk screen button characters.
There are two methods of detection: visual inspection and manual visual inspection. The inspector corrects their vision to 1.0 or above under standard lighting conditions, maintains a distance of about 40cm from the test object, and observes the silk screen characters on the buttons for 3-5 seconds at a visual angle of 45 °± 10 °; Machine vision inspection uses industrial cameras, lenses, light sources, and other equipment to capture button images and transmit them to image processing software. Dimension measurement, anime measuring instrument, anime measuring instrument, based on optical principle, judges whether it is consistent with the design drawings by measuring the length, width, spacing and other dimension parameters of the key silk screen characters; A three coordinate measuring instrument can measure the three-dimensional space of keys, not only measuring the plane size of characters, but also detecting the positional accuracy of characters in three-dimensional space. The testing process is divided into four steps: preliminary preparation, clarification of testing standards, and preparation of testing equipment; Sampling inspection, determining the sampling plan and selecting samples, randomly selecting samples from the production line or finished product warehouse to ensure representativeness of the samples; To implement the inspection, first conduct visual inspection to check the appearance quality of the characters, such as clarity, integrity, color uniformity, etc. Then use size measuring equipment to measure various size parameters of the characters; Adhesion test, operate according to the prescribed testing method and frequency, observe the detachment of characters after the test, and determine whether the adhesion is qualified. The final judgment result is determined based on the testing standards and sampling plan. For non-conforming products, corresponding measures are taken, and the reasons for the non-conforming products are analyzed. Improvement measures are taken to prevent similar problems from happening again. There are three key points for detection: environmental control, personnel training, and data recording and analysis.
By implementing the above detection methods, processes, and key points, the accuracy of silicone silk screen button characters can be effectively guaranteed, product quality can be improved, and market demand can be met. In actual production, appropriate testing schemes should be selected based on product characteristics and production scale, and the testing process should be continuously optimized to improve testing efficiency and accuracy.
