What is an automated optical check?
Automatic Optical Inspectorate (AOI) is a system that is able to visually check products to see if they are perfect or defective. AOI systems are used on various products such as car parts, food and labels. The most intense automated optical inspection system is used in the printed plate (PCB) industries from various problems that may endanger the efficiency of PCB. The Aoi program uses a combination of light and either a scanner or a camera to capture the product information and then compares it either with a master or with digital data. Although it is much faster than manual product control, the industry that creates products with a large variation may not consider AOI very useful, as this system can only process similar products. They would manually look for defects and ensure that all parts are correctly placed on the product. While at that time the effective, manual inspection is much slower and less accurate than automated optical control. This is because the Aoi system,Unlike human inspectors, he does not receive eye -abduction or accidentally forgets where the part is to go.
Automated optical control is available for many different products and each product receives its own set of inspection instructions. For example, if you check the fruit, the AOI system checks variations or bumps; For cars parts, the Aoi system will check to ensure that the part is the right size, is properly modeled and has no production deficiencies. The most advanced type AOI is used with PCB due to their complexity. AOI systems must check the correct soldering that all parts are present and no defects are present.
product check, automated optical inspection uses light and camera or scanner. Light is necessary to reduce the visual noise of the Andes to ensure that the camera or scanner can see the product without interference. The camera is less effective in this arenaBecause more than one may be needed for proper check. The scanners digitize visual information and can easily compare it with templates or data.
Ensuring the perfect product means that the automated optical inspection system must know what the perfect product is. One way to achieve this is to use the main template that includes constant scanning of the perfect product template and comparison with the controlled product. The second way is to insert the computer design data (CAD) into the system so that it can check the product against perfect data.
