Abstract: Wang Weidong, chairman of YH Technology, thinks that stand-alone automation is the cornerstone of smart manufacturing of lithium batteries. If domestic lithium power equipment wants to lead the world, first of all, it is necessary to make sophisticated single-machine equipment. Only when the single-machine technology is well done, can we have the opportunity to do segment integration and whole line integration, and can we have the opportunity to provide customers with a new mode of intelligent digital factory solution.

At the biennial CIBF exhibition，YingHe Technology released 4 series of 6 products at one time, which attracted the attention and resonance of the industry participants on site.

At the same time, YH Technology strengthens the R&D and technical strength of single-machine equipment while realizing the capability of whole-line delivery of turnkey project. This release of the coating& pressing& slitting machine, MAX winding series of products, die-cutting and stacking machine and other products are the best proof of winch technology's continued development and upgrading in this respect. After completing the new product release at the exhibition site, Xu Yi, vice-president of YH Technology, said this to high-technology lithium power.

Indeed, since 2017, YH Technology has invested great efforts in the research and development of stand-alone equipment and segment automation.

The thinking of Wang Weidong, chairman of YH Technology, is that stand-alone automation is the cornerstone of the intelligent manufacturing of lithium electricity. If domestic lithium power equipment wants to lead the world, first of all, it is necessary to make sophisticated single-machine equipment. Only when the single-machine technology is well done, can we have the opportunity to do segment integration and whole line integration, and can we have the opportunity to provide customers with a new mode of intelligent digital factory solution.

Around this direction, YH Technology has made breakthrough in actual performance for some of the single unit equipment introduced this time.

ARECONN-- Coating roller machine

By integrating the equipment of the model, the performance of the equipment was greatly improved, and the single-side density of the plane was <±1.0%, double sides <±1.2%,cpk>1.67；At the same time, the phenomenon of edge crack of the pole piece can be solved 100%, and 24 hours without stopping. It can also reduce the shrinkage and rewinding mechanism, reduce the investment in docking AGV, reduce the labor cost by 70% after the reduction of personnel, reduce the space energy consumption by 75%, and reduce the loss of repeated rewinding raw materials by up to 50%.

MAX-- Winding 

MAX winding series is another series of outstanding products launched at this exhibition. The brand was officially launched in 2017, laying a new benchmark for the industry. It adopts the six servo direct drive, realizing the functions of ultra-precision control, high-speed, ultra-thin adhesive paper bubble free adhesive, and rectifying the deviation of the front insert sheet.

"Japan has KAIDO, South Korea has KOEM and China has MAX.

"MAX represents the largest element in the set in mathematics, namely the maximum value. The brand of MAXwinderwill define the new meaning of Chinese winding mechanism and provide high-performance winder created by Chinese people for global battery production,"Xu Yi said at the press conference.

Longhe-- Automatic assembly line

Longhe Technology, owned by YH, focuses on the research and development of intelligent assembly line of lithium battery, liquid injection machine, helium inspection machine and other equipment. This exhibition automatic welding line, automatic packaging line, automatic two lines, the whole line automatic link, single machine can be independently automatic operation, the overall use of splitter rotary plate design, reduce material turnover time, efficiency of 20PPM.

Hehe—C&L Winding Machine

Hehe automation is a subsidiary of YH. Its core products are die - cutting machine, lamination machine, one - piece cutting machine. The original and domestically initiated cutting stitch all-in-one machine has the process of realizing the pole piece die-cutting without moving through the magazine, directly lamination and 100% without multiple pieces. Integration, covering only 1/2 of the space of a single machine; It effectively control that damage of pole pieces and remove the powder and raises the safety. Die-cutting of 120~150pcs/min and lamination of 0.25~ 0.3s/slice can greatly improve efficiency and save 20% of cost.

Huihe-- Intelligent digital factory

In addition to in-depth research on single-machine equipment, YH Technology has also increased its investment in the field of digital factories. The display of digital factories is the highlight of this exhibition. Delivered digital factories have been lively demonatrated, using the Internet, cloud services, 3D virtual simulation, information physics system (CPS), and the big data analysis and the advanced technology, the digital operation analysis design, the lean manufacturing, the smart transport and the whole life cycle, the quality control and so on, to build digital factories for lithium batteries manufacturing. It is worth mentioning that YH's assembling and machine shop has taken the lead in realizing the digital management.

The overall trend of the power battery industry is accelerating the differentiation, and the market share will further gather to the top. The capacity of the leading enterprises is not enough to support the future demand of the industry. Therefore, there is still a large space for the equipment demand of leading enterprises of lithium electricity. On the contrary, this makes it necessary for upstream equipment enterprises to improve their own research and development, technology and management level, and enterprises with obvious advantages in both stand-alone and automation integration will benefit from this.
