Inspection principle
Lithium-ion batteries have developed rapidly in recent years, but
due to the constraints of technology and production conditions,
there is a big contradiction between production capacity and
demand. At present, the detection method used for lithium battery
pole pieces is basically full manual visual inspection. The way.
However, there is a high probability of many defects after the pole
pieces are processed. All pole pieces must be inspected before the
battery lamination assembly, and the waste products, defective
products (can be used after processing) and genuine products are
identified and stored and processed separately.
The reliability, stability and efficiency of manual detection
cannot be effectively controlled, and the labor cost during the
epidemic is currently high, and the labor-intensive production
directly restricts the low-cost production of lithium batteries.
Due to the continuous shortage of human resources, labor costs
remain high, and this status quo will continue, and the cost
pressure of lithium batteries has not been released.
Inspection details
- The improvement of production automation will improve this
situation. In order to further reduce production costs and improve
product quality, we have designed and developed a lithium battery
pole piece machine vision inspection equipment to speed up the
automation level of the lithium battery industry.
- Before the pole piece is coated and baked, the coating width is
detected online in real time with machine vision, the measurement
data is provided in time, and the coating width is corrected in
real time.
- Due to the difference in the coating width in the light map, the
visual grasping edge does not fit, so the width of the coating
changes. In the visual inspection, the result can be given quickly
and accurately in real time and the OK/NG can be judged.
- The popularization of machine vision inspection equipment has
subverted the existing detection method using manual visual
inspection. Instead, machine vision automatic inspection is
adopted, which speeds up the efficiency of industrial automation,
reduces the cost of enterprises, and relatively improves the
inspection effect. The inspection effect is stable and greatly
improved. Improve the quality of products put on the market.
Camera position
The system uses four cameras, the first camera is used to detect
the width of copper tabs on the front of the battery pack, the
width of copper tabs, the detection of copper tabs entering the
shell, the width of aluminum tabs, the width of aluminum tabs, the
width of aluminum tabs, and the width of aluminum tabs. Case
detection, the width of the polar tabs, the second camera is used
to detect the width of the front side seal of the battery pack, the
presence or absence of the bottom seal, the detection of the
sealing surface, and the detection of pinching.
And the third camera is used to detect the width of the copper tabs
on the back of the battery pack. , copper tab width, copper tab
into the shell detection, aluminum tab glue width, aluminum tab
width, aluminum tab into the shell detection, two tab width, the
fourth camera is used to detect the width of the back side seal of
the battery pack, the bottom Detection of seal presence, sealing
surface detection, and pinch detection. The four cameras open up
threads respectively, start the thread when detection is required,
and suspend the thread when detection is not required.
