Brief description of the effect of current high end lithium electrode detection up to 70 %

Extreme film coating is one of the key technologies for the core competitiveness of power battery energy density. In order to improve product yield and efficiency, and to avoid defects such as lack of materials, leakage coating, and folds in the process of wafer manufacturing, battery companies will carry out a strict inspection process.

With the higher and higher level of battery safety protection in power battery companies, it is obvious that power battery companies are also increasingly demanding the detection of polar films.

Aiming at market opportunities, deep cultivation of the machine vision industry detection for 30 years, WINTRISS testing technology company(hereinafter referred to as "micro-vision") accelerated the pace of development of the Chinese market.

According to Microvision sales director Wen kongming, the company has now become BYD, wan Xiang A123, guoxinggao, guoneng and other domestic power battery suppliers of more than 30.

Gaogong Li-electricity has learned that Microvision as a transcontinental has accumulated for 10 years in the lithium industry in China.

Why can quickly win the recognition of the above many high quality battery enterprises in China? In Wengongming's view, this is mainly related to the company's technology patents and industry experience in smart cameras.

Microvision from smart cameras has many patented visual software and unique light source designs developed by itself in the field of power batteries. It can detect various surface defects in the production process of polar films in real time, and has high imaging resolution, greatly improving customer production efficiency. This is precisely the secret that Microvision hides the strong market competitiveness.

Established in 1989, Microvision is headquartered in San Diego, California, and focuses on the development and application of smart cameras. Its main product is an industrial detection device based on machine vision, and its self-developed high-speed scanning CCD camera. It can detect 100 % surface defects on continuously running coil, strip or sheet materials online and provide accurate product quality information. It is mainly used in electronic materials, optical films, non-woven fabrics, papermaking, plastic films, metals, and glass industries. Wait.

Specifically, compared to other polar film detection equipment in China, Microvision has the following 5 product advantages:

1. Has the world's most stable system-VxWorks operating system. The system has been widely used by the U.S. military in high-precision technologies such as communications, military,special, andspecial, and in areas where real-time requirements are extremely high;

2. The smart camera is equipped with the most professional German Rhodes lens to ensure that the camera can scan the most original and true picture of the defect, and to the greatest extent to avoid accidental inspection;

3. Carry advanced intelligent classification software, use artificial intelligence algorithm(AI technology) to conduct in-depth self-learning of defect images online, achieve accurate identification and classification of defects, allow manual intervention in reading and writing rules, and truly achieve classification of indistinguishable approximate defects. The detection rate and classification accuracy can reach 99.5 <UNK>;

4. The lithium power industry has accumulated for ten years. It retains the most complete database of various "problems" that exist in the detection process of lithium battery Polaroids, and updates them in real time to facilitate customers 'use. At the same time, it saves customers a large number of Polaroids for testing equipment. Debugging;

5. Based on the production developed by Microsoft SQL database platform, quality reports are flexibly used to provide quality production personnel with various production quality reports.

Taking Microvision as an example, it can detect defects on the production line of positive, negative copper foil continuous coating and intermittent coating.

Microvision claims that the company's advanced defect intelligent classification engine can accurately identify different types of defects based on the image characteristics of defects, help users effectively improve quality management, and further improve the production process. All detected defect data is displayed on the screen in real time and stored in the SQL database system.

In addition to polarographic detection, the micro-vision device can also be used to detect surface defects such as pinholes, bright spots, oil spots, and black spots in the diaphragm production process. Through the accurate scanning of smart cameras, the real-time response is on the integrated computer of the general control room. Online detection consistency and stability are superior to domestic and foreign detection equipment.

At present, Microvision has a number of high-quality partners in the film and diaphragm equipment at home and abroad: Japan's Toray, South Korea's PNT, Dongguan Yakang, and Huizhou Winner. Data show that by 2017, Microvision has more than 1,000 system applications installed in the new energy industry in North America, Asia and Europe.

"At present, the dry market(share) we occupy more than 50 %, and the wet method is about 75 % -80 %. "Wen Gongming introduced to Gaogong Lithium, the domestic wet diaphragm leader Shanghai Enjie, Hefei Xingyuan; The dry method diaphragm well-known enterprises ZTE new materials, 90 % of science and technology equipment use micro-vision products.

With the outbreak of the Chinese power battery market, Microvision has also expanded its market map. At present, Microvision(China) has set up a business center in Shanghai, which mainly coordinates domestic sales and markets; Set up assembly plant in Suzhou, responsible for technical support; It has an office in Shenzhen to perform pre-sale after-sales service, installation and commissioning work, and provide 8 hours of on-site service for customers in the Yangtze river delta and Pearl river delta. Through the establishment of three major centers in Shanghai, Suzhou and Shenzhen, Microvision(China) has been able to respond quickly to customer needs.
