新能源行业的快速发展自然而然的带动了锂电池的发展，虽然工艺日渐成熟，但生产的前、中、后仍然会存在一些人工无法检测出来的缺陷，想要严格把控好锂电池的品质，必须引进先进的自动化检测技术，将废品、次品 ( 可处理后利用 ) 和正品辨识出来后分别存放和处理，在出厂前必须进行严格的质量管控。
The rapid development of the new energy industry has naturally led to the development of lithium batteries. Although the process is increasingly mature, there are still some defects that cannot be detected manually before, during and after production. To strictly control the quality of lithium batteries, advanced automatic detection technology must be introduced, and waste products, defective products (which can be used after treatment) and genuine products must be identified and stored and processed separately, Strict quality control must be carried out before leaving the factory.
随着市场对电池能量密度的追求，铝壳逐渐成为主流。电芯生产完成后需要进行入壳组装，铝壳质量直接关系到电池品质。传统人工目检受制于人眼速度、精度、工作环境、客观性和可靠性等因素，检测效率低，易错检、漏检，标准不一，稳定性差。针对方形锂电池铝壳外观缺陷，昂视在不影响客户产线正常运转的情况下，制定了科学的视觉检测解决方案。
With the market's pursuit of battery energy density, aluminum shell has gradually become the mainstream. After the cell production is completed, it needs to be assembled in the shell. The quality of the aluminum shell directly affects the quality of the battery. The traditional manual visual inspection is subject to factors such as human eye speed, accuracy, working environment, objectivity and reliability. The detection efficiency is low, it is easy to be wrong and missed, the standards are different, and the stability is poor. In view of the appearance defects of the aluminum shell of the square lithium battery, Onvision developed a scientific visual inspection solution without affecting the normal operation of the customer's production line.
