    How to Choose Visual Inspection Machine? May 25, 2024
    Deploying visual inspection systems has become the first choice for manufacturing enterprises to transform quality inspection and improve product quality. However, enterprises that are not familiar with visual inspection equipment often have certain misunderstandings about the value of visual inspection equipment when choosing. Today, we will summarize several types of problems that enterprises face how to choose visual inspection machines and systems.     Question: If one machine can inspect all products? No, it's not possible. If a company wants to purchase a set of AI visual inspection equipment to test all its products, it is not feasible at this stage.   Although AI visual inspection equipment is compatible, it has a range of requirements for product specifications. Currently, many manufacturing companies have a wide range of products, and products with different materials, shapes, and sizes require different light sources, cameras, and algorithms.     Keye AI image visual detection has a certain degree of compatibility, but the two products differ greatly and it is also difficult to achieve complete compatibility. The visual inspection equipment for bottle caps is compatible with two products with a height difference of no more than one-third and a width difference of no more than half, and there are no irregular caps. Whether the height or width difference is too large, using the same equipment for inspection will affect the final factory quality. Customized solutions based on product characteristics are necessary to ensure the factory quality of the product.     Question: Will setting excessively high testing standards lead to a low yield rate? Yes. Some manufacturing companies, when purchasing vision inspection systems, do not establish inspection requirements based on the actual situation and acceptance standards of the enterprise, but instead use theoretical standards to develop inspection standards. Finally, when debugging and running, it was found that the yield rate was too low, and the visual inspection system was not accurate enough. In fact, this kind of problem belongs to the use of useless ultra-high standards. Enterprises should develop testing standards based on actual situations, increase testing items appropriately to improve testing standards, improve product quality, and maintain market competitiveness.   Question: Is the value of visual inspection systems only reflected in reducing labor costs? No, it's not. A set of AI visual inspection equipment not only saves labor costs, but also reduces the operating costs of enterprises. To improve efficiency, enterprises often choose automated equipment to replace manual labor, which not only improves production capacity and quality, but also reduces operating costs. Keye's AI image visual inspection equipment on a single production line can help enterprises save 3-5 inspection personnel and ensure uniform product quality standards, enhancing customer recognition of the enterprise. In terms of operating costs, Keye's AI image visual detection has played a more significant role. For example, visual inspection of bottles can directly sell qualified products after inspection, and defective products that have been removed can be further processed or reused. The product value can be diversified and maximized.       Question: Can a visual system be used for high production? Suggested to use, but it depends on the business situation of the enterprise. A large output is indeed more suitable for choosing a visual inspection system. From the long-term development strategy of enterprises, manual testing has limited speed, low efficiency, and is more suitable for using automated equipment for testing in large quantities. Although some individual products have low value, using manual visual inspection may result in missed or false inspections. If the products are found in the hands of downstream enterprises and do not meet the standards, they may choose to return them, causing certain losses to the enterprise. Over time, this is not conducive to the long-term development of the enterprise. Therefore, when the production volume of the enterprise's products is large, it is recommended to choose visual inspection equipment. One investment can benefit the enterprise for a lifetime.     Therefore, the choice of AI visual inspection equipment by enterprises is not a direct manifestation of high quality. Only by making reasonable use of AI visual inspection systems to control product quality and effectively eliminate the outflow of defective products can we avoid complaints from end customers and win their trust in the enterprise.    
  • Comparison of the Characteristics of Manual Inspection, Traditional Algorithm Visual Inspection, and AI Algorithm Visual Inspection
    Comparison of the Characteristics of Manual Inspection, Traditional Algorithm Visual Inspection, and AI Algorithm Visual Inspection May 23, 2024
    There are currently three inspection methods in the production of plastic packaging containers. The first is traditional manual inspection, which detects defects in the product through eye observation. The second is machine vision inspection, which is based on traditional algorithms. The third is the latest AI algorithm visual inspection system. With the increasing quality requirements for packaging products in the global industry, the efficiency of defect inspection will also become more stringent. Below we will compare several existing testing methods, which will help people find the appropriate testing method to better meet quality requirements and reduce enterprise operating costs.     Due to subjective factors, low efficiency, and susceptibility to fatigue, manual vision inspection cannot guarantee the efficiency and long-term stability. Traditional algorithms vision inspection have many parameters and rely heavily on professional debugging personnel. Poor adaptability, high false detection rate while ensuring detection accuracy, resulting in low detection efficiency. Deep learning AI vision inspection system enables machines to learn the inherent patterns and representation levels of sample data, enabling them to have the ability to analyze, learn, and reason logically like humans. Excellent long-term performance and stability, with efficient detection accuracy.     Human visual inspection has a relatively low recognition rate for colors, which is easily influenced by human psychology and cannot be quantified. Then, machine detection color discrimination can be quantified. For example, human eyes can only recognize 64 grayscale, and machines have strong grayscale recognition ability. Currently, 256 grayscale levels are generally used, and the acquisition system can have grayscale levels such as 10 bit, 12 bit, and 16 bit. The resolution of the eyes is poor, and they cannot view small targets with high resolution. Machines can observe targets at the micrometer level, but the human eye has a slow observation speed. The 0.1 second visual persistence makes it difficult for the human eye to see fast-moving targets clearly. On the other hand, machines have a fast speed, with a shutter time of about 10 microseconds and a high-speed camera frame rate of over 1000. The processor speed is getting faster, and the human eye range is narrow. Visible light devices in the 400nm-750nm range have a wide detection range, ranging from ultraviolet to infrared spectra. Human visual inspection has poor adaptability to the environment, and there are many situations that can cause harm to people. Machine vision inspection has strong adaptability to the environment, and protective devices can also be added. Human eye detection has low accuracy and cannot be quantified. Machine vision has high accuracy and can reach the micrometer level, making it easy to quantify. Relying on human detection also has other subjectivity, psychological influence, and fatigue.     From the above data and analysis, it can be seen that replacing human visual inspection with machine vision inspection will be a trend, especially with the continuous increase in labor costs worldwide. Whether it is from the perspective of production costs, management standards, or detection efficiency, the new generation of AI algorithm visual inspection will be favored by the market. Currently, the visual inspection system supported by the latest generation of AI algorithm by Keye has been increasingly recognized by more customers in domestic and international markets, and has become a leading enterprise in the plastic bottle, cap, printing and other industries. At the same time, it has played a good role in promoting the real landing of artificial intelligence in the packaging inspection market.
