[0002] Domestic color-coated plate production lines currently rely mainly on human visual inspection to detect surface defects of online steel plates. The finished product cutting size is automatically cut by the equipment. Inspection sampling relies on manual sampling to measure parameters such as length, width, and diagonal, which may result in false detection, missed detection, and hysteresis. The production line currently uses micrometer calipers to manually measure the plates for sampling. The disadvantages are low efficiency, easy measurement errors, and non-intuitive size reading. A production line team needs to be equipped with multiple quality inspection personnel at the same time. The inspection product is not objective and standardized. The finished product size and defects vary from person to person, resulting in high direct costs, which directly affects the competitiveness of the company's products. In response to the above problems, the applicant has specially researched and developed a finished product size and defect detection system on the home appliance color coating production line in order to improve the detection accuracy and standardize the detection process while also saving labor costs and material loss costs and improving the competitiveness of the company's products.
