Great news! Great news!
Hi, family, today C Xiao C invited a good friend to my live broadcast room – lithium battery. He is now a “net celebrity” in the energy storage market. why is it red? I have data!
The data shows that in 2021, the national lithium-ion battery output will be 324GWh, a year-on-year increase of 106%. Among them, the output of consumption, power, and energy storage lithium batteries will be 72GWh, 220GWh, and 32GWh, respectively, an increase of 18%, 165%, and 146% year-on-year. The output of the four key materials for lithium batteries has grown rapidly. According to the calculations of research institutions, the growth rate of cathode materials, separators, and electrolytes is close to 100%. The total output value of the lithium battery industry has exceeded 600 billion yuan.
Next, the microphone is handed over to the lithium battery….
Lithium battery play
Hello CC-Link family, I am a lithium battery. Initiating a new round of energy transformation in the world, the development of the energy storage industry has become the general trend, and I have become the darling of the market, but there is a long process for me to grow from a copper foil baby to a lithium battery. The main equipment includes a coating machine. , slitting machine, winding machine/laminating machine, etc., among which mixing, coating, drying and slitting belong to the front-end process, while lamination, welding, liquid injection, packaging, chemical formation, packaging, etc. belong to the back-end The general process is shown in the figure below:
Lithium battery industry process map
Of course, my rapid growth is inseparable from the help of CC-Link IE TSN, especially on the stacker equipment. Today I will show you the advantages of CC-Link IE TSN network.
Compared with the traditional stacking machine, I really like the stacking machine built using the CC-Link IE TSN network. This equipment realizes the stacking of anode sheets, cathode sheets, and separators into cells through zigzag stacking.
Lamination equipment and zigzag lamination method
Therefore, this equipment uses the world’s first CC-Link IE TSN Industrial open bus network developed based on TSN technology as the bus network of motion control equipment. Its main force is the latest MELSERVO-J5 servo controller launched by Mitsubishi Electric for control , In the equipment debugging stage, due to the stable and high-speed transmission speed of the CC-Link IE TSN network, the entire laminated equipment is very stable during operation. If high-speed motion control is to improve the overall production cycle, then the deviation correction of the isolation film is to improve the accuracy of the entire product. This process mainly uses two deviation corrections. The first-level deviation correction is placed at the position of the unwinding roll, and the servo mount 32: The reducer of 1 controls the unwinding equipment through the screw rod; the second-level deviation correction mainly uses the servo to directly control the screw rod to realize the deviation correction operation, because the second-level deviation correction is the last process before lamination, if the reducer is used, the overall accuracy will be affected At present, the accuracy can be controlled within 0.3mm. If more level correction is used at the discharge port, the accuracy can be controlled within 0.1mm.
Primary correction and secondary correction
Of course, this is only the finished product of this process, and subsequent operations such as welding tabs are required. Because only through these processes can I become an excellent lithium battery.
C Xiao C wants to highlight the key points for everyone!
Before formally understanding the communication bus network, let’s first understand what is TSN technology. TSN technology is Time Sensitive Networks, which is a time-sensitive network in Chinese. Its predecessor is AVB technology, that is, audio and video bridging technology, which is mainly used in live broadcasting and automobile central control. With the improvement of its own protocol, the IEEE802.1 working group officially changed the name of this technology to TSN in 2012. technology. TSN is not a single standard or protocol. It is composed of multiple protocols. So far, its protocol standards are still in the process of continuous improvement and supplementation. As an extension protocol of ordinary Ethernet technology, the TSN standard aims to make an effective supplement to ordinary Ethernet in terms of real-time performance, time synchronization, high precision, and security. In the past, the common Ethernet protocol was rarely used in the industrial field bus network because it did not meet the requirements in terms of security and high precision. Therefore, the TSN technology expanded by the common Ethernet protocol is very suitable for the industrial field.
CC-Link IE TSN, as the world’s first gigabit industrial open network using TSN technology, was officially released globally by CLPA in November 2018. It only needs one network cable to connect a variety of different protocols, including CC- Link IE TSN protocol, TCP/IP protocol, UDP, MODBUS/TCP, SLMP, etc., and can also be compatible with various other industrial open bus network protocols based on TSN technology.

At the same time, due to the time synchronization and time division functions of TSN technology, you can set different refresh cycles according to the requirements of your own devices during use. In the traditional network, in the same network, the communication between each device The cycles are consistent, but CC-Link IE TSN can configure different communication cycles for different devices. For example, devices that require high-speed control such as servo amplifiers can be configured with high-speed communication cycles, while remote I/O, frequency conversion, Temperature control equipment, etc. can be configured with a medium-speed communication cycle, so that gigabit network re
