Advantages and disadvantages of machine vision inspection system and manual visual inspection than

Human can continue to work effectively for a limited period of time, and in the repeated mechanization of the detection process is easy to fatigue, lack of energy, so the detection efficiency is relatively low.

Machine vision inspection is much faster, capable of detecting hundreds or even thousands of components per minute. Especially when detecting high-speed moving objects, machine vision inspection can improve detection efficiency. In addition, the machine is able to work continuously 24 hours a day.

2, higher accuracy

The human eye has physical limitations, even if it relies on magnifying glasses or microscopes to detect the product, it will be subject to subjectivity, physical energy and other factors, and can not guarantee accuracy. And standards can vary from inspector to inspector.

Machines are not subject to subjective control, as long as there is no difference in parameter settings, multiple machines with the same configuration can guarantee the same accuracy.

3, the overall cost is lower

Manual testing is a long-term, ongoing cost investment, traditional product testing is a labor-intensive field. And today's labor and management costs are rising.

Machine vision inspection of the investment is mainly early, one-time investment to ensure long-term output. And the machine is more effective than manual inspection, in the long run, the cost of machine vision inspection is lower.

4, information integration

A person can only detect one item at a time, when the manual inspection is faced with different inspection content, it can only be accomplished through the coordination and cooperation of multiple workstations.

Machine vision inspection can measure multiple technical parameters at once through multi-station measurement methods, such as the contour of the product to be inspected, size, appearance defects and product height.

5, digital statistical management

Machine vision during the work of all the measurements generated during the data can be copied independently or through a network connection to copy out, easy to production process statistics and analysis. At the same time, the staff can export the specified measurement data and generate a report after the measurement, without having to manually add one by one.

6, can be repeated for a long time continuous work

Machine can continue to complete the detection of 24 hours, will not feel fatigue. The human body has limited energy, long repetitive testing work is bound to feel tired, then it is easy to miss, misdiagnosis, error detection and other errors, resulting in significant losses.

7, can be applied to the dangerous detection environment

The machine can be in the harsh, dangerous environment, as well as in the human vision is difficult to meet the needs of the occasion to complete the detection work.

8, will not cause contact damage

Machine vision in the process of detecting the workpiece, do not need to contact the workpiece, will not cause contact damage to the workpiece. Manual inspection must be contact detection of the workpiece, easy to produce contact damage.

9, more objective and stable

Manual inspection process, the test results will be affected by personal standards, emotions, energy and other factors. The machine strictly follows the set standards, and the test results are more objective, reliable and stable.

10, to avoid human contamination

Some special production lines, such as pharmaceutical production areas, the production and testing process of health requirements are extremely high. Machine vision inspection can avoid human contamination problems, to ensure the cleanliness and quality of production inspection.
