Due to the limitations of manual inspection conditions, even with magnifying glasses or microscopes, subjectivity affects accuracy, and different inspectors have different standards; machine Vision inspection system is unaffected by subjective factors; with accurate parameter settings, inspection results maintain consistent accuracy.
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 automotive industry was an early adopter of machine vision inspection systems. The high demands of automotive parts production and assembly make it a high-tech industry requiring advanced automated visual inspection technology to ensure smooth production at every stage.
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.
Many aspects of automobile manufacturing now use automated equipment, eliminating manual operation. However, ensuring part quality requires reliable inspection technology.
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.
Automotive parts visual inspection falls under machine vision systems, used for measuring dimensions, detecting dimensional defects, missing flanges, incorrect weld positions, incorrectly welded nuts, missing welds, sorting, and missing machining on automotive hardware components.
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.
Automotive parts visual inspection systems identify image features, analyze and calculate stamping part characteristics, determine product conformance, and output control signals. Automatic detection provides abnormal signals and OK/NG outputs, storing images of non-conforming parts on the industrial computer.
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.
1. Dimensional inspection: Core dimensions are measured based on the product outline in the image.
Check the size of the product, and check the core size according to the outline shown by the product photo.
2. Defect detection: Imaging with front lighting identifies surface defects such as missing material and scratches. Higher-resolution cameras improve micro-defect detection.
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.
3. Contaminant detection: Identifies surface contamination.
Detection of pollutants, whether the surface is contaminated by other stains, etc., can be identified.
4. Integrity check: Detects cracks or missing machining.
Check the integrity, whether the product has cracks, etc., or there are missing processing places.
5. Assembly verification: Verifies proper assembly (e.g., door hinges) using visual inspection.
Assembly verification, such as door hinge, whether the assembly is in place, can be completed by visual inspection.
