Screws, as basic fasteners, are widely used in various industries, and their quality directly affects the safety and service life of the products. Therefore, we attach great importance to testing product quality. Xun Yucheng introduced CCD machine vision inspection equipment in 2018, which significantly improved production efficiency and quality control. Automated CCD can achieve high-speed continuous inspection, which greatly reduces the company's inspection costs in terms of efficiency. It can complete the inspection of different projects by multiple people with only one device, and the inspection line of 5-6 people has been reduced to 1-2 people. CCD uses optical imaging principles and image processing algorithms to quickly and accurately detect the appearance, size and position parameters of the product. The sub-pixel algorithm can measure the size with an accuracy of plus or minus 0.003mm, and the defect recognition rate exceeds 99.5%. The quality inspection of screws after production is an important link before the product is circulated. This solution not only reduces labor costs, but also ensures product quality, and is recognized and trusted by customers.
