新能源行業的快速發展自然而然的帶動了鋰電池的發展，雖然工藝日漸成熟，但生產的前、中、后仍然會存在一些人工無法檢測出來的缺陷，想要嚴格把控好鋰電池的品質，必須引進先進的自動化檢測技術，將廢品、次品 ( 可處理后利用 ) 和正品辨識出來后分別存放和處理，在出廠前必須進行嚴格的質量管控。
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.
隨著市場對電池能量密度的追求，鋁殼逐漸成為主流。電芯生產完成后需要進行入殼組裝，鋁殼質量直接關系到電池品質。傳統人工目檢受制于人眼速度、精度、工作環境、客觀性和可靠性等因素，檢測效率低，易錯檢、漏檢，標準不一，穩定性差。針對方形鋰電池鋁殼外觀缺陷，昂視在不影響客戶產線正常運轉的情況下，制定了科學的視覺檢測解決方案。
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.
