Visual inspection plays a vital role in industrial automation. It has become the driving force for factories and enterprises to improve production efficiency and product quality. Now, machine vision inspection has been widely used in various industries, next take a look at its application and advantages in the field of new energy batteries.

Application of machine vision inspection in new energy battery field

Machine vision detection technology can be applied to the whole process of battery production, in size measurement, appearance defect detection, character recognition and other aspects instead of manual work.

Here are some examples:

Detection of the upper and lower alignment of battery electrode pieces, such as: white space size, coating width size, upper and lower coating alignment, etc.

Burr detection of battery electrode, automatic judgment of burr shape and size;

Appearance defect detection of battery electrode;

Battery lamination size detection;

Detection of appearance defects of battery laminates, such as wrinkled diaphragm, wrinkled long glue, crooked long glue, uneven laminates, uneven diaphragm, folded diaphragm, etc.;

Battery package size inspection;

Inspection of appearance defects of battery packaging, such as packaging wrinkling, pressing ear, poor glue of the ear, crushing, clamping, corner pits, etc.;

Cell thickness measurement and appearance defect detection, such as: damage/leakage, pole fold, edge foreign body, bump, depression, scratch/indentation, dirt, surface wrinkling, etc.;

Detection of appearance defects of battery adhesive, such as bad adhesive, bad scan code, bad external size, etc.

New energy battery industry application of machine vision inspection advantages

Compared with manual detection, machine vision detection can play a greater advantage when applied to the new energy battery industry.

1, high accuracy

Machine vision detection has no obstacles in subjective emotions, and the detection results are more objective and reliable, which can ensure accuracy.

2, can be repeated for a long time

The machine will not be tired and can work 24 hours a day.

3. High efficiency

Machine vision detection speed is much faster than manual detection, can detect hundreds or even thousands of components per minute. Especially when detecting high-speed moving objects, machine vision detection can improve the detection efficiency.

4. Low cost

A set of equipment can be worth the work of four or five workers, labor cost is a long-term continuous investment, and now the cost of workers is also increasing, machine vision detection equipment is a one-time investment. In the long run, the cost of machine vision inspection is much lower.

Not only in the field of new energy batteries, PCB circuit boards industry, semiconductor industry, precision parts industry, food industry, textile and clothing industry, are also widely used visual inspection technology. Automatic detection based on machine vision and digital image processing technology will replace manual detection and become the inevitable direction of future development.
