Power battery power jack "behind" double wide high speed coating wisdom made in China

As the world in 2017Power battery sales champion, is leading China lithium electricity surrounded by industry breakthrough, Japan and South Korea, emergence as a global industry leader.As CCTV documentary "power jack", China's largest power the battery6 micron copper foil production base, which make the power battery production line to appear publicly for the first time.

One double-sided high-speed 6 micron coating technology especially attracted much attention.New jiapto extension with three years to develop the world's first batch of adapt to 6 um copper foil high-speed double coating machine, coating production speed of more than 80 m/min, width 1000 mm, especially solve the problem of coating on 6 micron copper foil, it is domestic coating beyond the major breakthrough in the case of imported equipment.In the actual production to get user recognition and praise.Symbol of the new fine extension coating fully replace imported, market attention.

Talked about the "double wide high-speed coating machine", the new jia company general manager QiXiaoDong self-confident, said the new extension of this coating machine in a parallel uniformity, oven, wind speed, tension roll stability as well as the overall installation accuracy, performance and ability, already can rival with their Japanese counterparts, even already leads the world in certain parameters, truly achieve the core equipment of power battery high-end "wisdom made in China".

As "name card" of domestic high-end coating machine, set up 12 years, new jiapto's always driven enterprise, located in technology is the best choice of the lithium electricity equipment import substitution.New fine billiton also foreign introduced its core products - "double wide high speed coating" on a series of black science and technology.

1,Implement 6 um copper foil in the double wide applications of high speed coating machine

Double coating machine is at a high speed the lithium battery one of the largest equipment in each process and about 80 meters in length, width of 8 meters, 7 meters high, weight of two hundred tons, whether it is equipment of integral rigidity and strength of the accused or the installation of the equipment at the scene of the production of precision is critical, any deviation, will cause the copper foil fracture, it is difficult as the rockets core components.

If the handle is not good, later in the equipment of continuous use, will affect the precision equipment, and produces some unstable factors.Parallel level of the roller and oven wind velocity uniformity is realizing 6 um copper foil production key point, the new fine extension with years precipitation established a professional engineering team, through the design, the machining accuracy and precision of installation and debugging experience of strict control, in design and installation accuracy at the same time, also once installed.

2, Solve the artificial detection alignment, CCD detection and closed-loop adjustment (positive and negative size detection and alignment degree closed-loop control).

Power battery on the edge of the sheet of the front side of the closed loop alignment time requirement is very high, how to guarantee and after the coating, coating process real time adjustment, real-time detection.New jiapto through high-speed CCD camera to detect the critical dimensions, real-time detection compared calculation, and to transfer the data to the computer storage, and analysis data to determine whether to be adjusted, ensure that small scale fluctuation near the required value.

3,Rolling roll diameter, large automatic for the connection of AGV automatic up-down material.

When the coating width 1000 mm, spreading speed of 80 m/min, the new jiapto's double wide high speed coating automatically and rolls up to a maximum of 1.2 m diameter, docking with the AGV automatic up-down material, cancel the manual operation, can greatly improve the production efficiency, reduce downtime.New jiapto's works closely with customers, have been implemented automatic docking of AGV is up and down.Only new jiapto company took the lead in domestic implementation and application.

4,Solve many period of high precision double closed-loop tension control

Double high-speed coating machine design has six period of tension, tension of each section has a unique meaning, difficulty is also relative to the single layer twice the three sections of the tension is not digital, a double closed loop speed and tension is the powerful guarantee to realize high speed coating.New jiapto Rio state by using CNC high-speed PLC, realize microsecond response, coupled with reasonable optimization software programs, let the product in the operation of high-speed motionless, so as to realize the tension stability.

In the past a few years, along with the high-speed development of domestic power battery industry, also promote the growth of the domestic equipment by leaps and bounds.New jiapto Rio as a core subsidiary of Shanghai putailai group, to provide intelligent and efficient solutions for power battery production, new energy industry in the international competition in the future, create and lead the coating and other high-end core equipment comprehensive import substitution, the implementation of new energy industry manufacture of "Chinese core".High speed, precision, energy-saving, localization services, research and development of core technology of all will be the core of the new fine extension with foreign competition advantages, to provide customers with unique competitive force.
