Due to the limitation of manual detection conditions, even if the products are tested by magnifying glass or microscope, the accuracy can not be guaranteed, and the standards of different inspectors will also have differences; the machine vision inspection system is not affected by the subjective factors, as long as the parameters are set accurately, the test results can maintain the same accuracy.
The industry where machine vision inspection system was applied earlier belongs to automobile industry. Automobile has high requirements in parts production, assembly and other aspects. It is a high-tech industry, which needs to use a lot of advanced automatic visual inspection technology to ensure the smooth production of each link.
At present, many aspects of automobile manufacturing have been operated by using equipment automation, without manual operation. However, in order to ensure the qualification of each part, it is necessary to use a very reliable technology for inspection.
The vision inspection of automobile parts should belong to the category of machine vision system, which is used to measure the size of automobile hardware workpiece, size defect, missing flanging, welding wrong position, nut wrong welding, missing welding, sorting, missing processing, etc.
The visual inspection system of automobile parts can identify the image features, analyze and calculate the feature information of stamping parts, judge whether the products meet the requirements, and output control signals. The detection process is automatic detection, abnormal signal is given when abnormal, and the corresponding output OK or ng signal, and the image of unqualified parts is stored in industrial computer.
Check the size of the product, and check the core size according to the outline shown by the product photo.
Defect detection, such as obvious material shortage, scratches, etc., can be judged whether there are surface defects according to the imaging and the front light source. At present, according to the application of camera technology, the higher the pixel, the more obvious the judgment of micro defects.
Detection of pollutants, whether the surface is contaminated by other stains, etc., can be identified.
Check the integrity, whether the product has cracks, etc., or there are missing processing places.
Assembly verification, such as door hinge, whether the assembly is in place, can be completed by visual inspection.
Shandong Hongbao Automation Co., Ltd. customized visual inspection system for different types of manufacturing enterprises has been widely used and praised in 3C electronic industry, home appliance industry, automatic packaging, food packaging, chemical industry, textile and other fields.
Machine vision detection system is recognized as a high accuracy detection technology in the industry, with unique advantages, plays an important role in various industries.
