The new high-speed double-layer coating machine independently developed by Haoneng Technology has performed PK with imported equipment from Japan and South Korea on the production line, surpassing Japan and South Korea at 80m / min at a speed of 120m / min, and successfully counterattacked Japan and South Korea again.
This new type of high-speed wide-width double-layer extrusion coating machine independently developed by Shenzhen Haoneng Technology Co., Ltd. (hereinafter referred to as Haoneng Technology) has super high-speed, high-precision, high-intelligence, and high-efficiency drying technologies. It has added a big weapon to the intelligent manufacturing of China's power batteries, and has also made a strong name for domestic coating machines in terms of replacing imports and upgrading product performance.
"This coating machine has a running speed of 120m / min, a 1100mm wide coating, and high-speed coating on 6 micron copper foil without wrinkling and deviation, which is a major breakthrough for domestic coating machines beyond imported equipment. "Cheng Jianjun, Chairman of Haoneng Technology, said in an interview that the successful release of the high-speed wide double-layer extrusion coating machine means that Haoneng Technology has once again taken the forefront in the field of coating machine technology and continues to lead the coating industry. Machine technology development direction.
It is understood that this high-speed wide double-layer extrusion coating machine developed by Haoneng Technology has coating speed, coating width, area density accuracy, yield, automatic closed-loop control of area density, efficient drying, and tension stability. As well as the overall installation accuracy and other performance indicators can be comparable to Japan's imports, and even surpass imports in certain parameters, to achieve the domestic intelligence of the core lithium-ion high-end equipment.
In fact, since its establishment in 2005, Haoneng Technology has been focusing on R & D and manufacturing of coating machine equipment, mainly producing high-precision lithium-ion battery positive and negative plate coating machines, slitting machines, roll tying equipment, battery separator coating, and agitators. And other equipment, and are widely used in high-end markets, becoming the main supplier of high-end lithium battery manufacturers in the industry.
As a representative of domestic high-end coating machines, Haoneng Technology introduced a series of highlights on its core product-"high-speed wide-width double-layer extrusion coating machine".
1.120m / min ultra-high speed coating leads the application of domestic coating machine
The coating process is one of the key processes of pole piece manufacturing. There are many factors that affect the coating quality, including the manufacturing accuracy of the coating head, the stability of the equipment running speed and the control of the tension during the movement, and the amount of air pressure during the drying process. And temperature curve control will affect the coating quality.
In terms of key coating speeds, the running speed of domestically produced coating machines is generally below 80m / min, and the speed of low-end equipment is 20m / min, and the actual running speed is lower. The coating speed of the new coating machine of Haoneng Technology was 80m / min for the first time when it was installed and debugged, and it was directly increased to 120m / min under stable operation, which greatly improved This improves the efficiency of power battery production.
It is worth noting that in addition to the highest coating speed of 120m / min, the coating width of this coating machine has also reached 1100mm, and the coating width is doubled than that of ordinary coating machines, further improving the coating. effectiveness.
2.Stable surface density accuracy ≤1%
During the coating process, if the surface density of the pole pieces is different, one piece will be over-rolled and the other will be under-rolled during the rolling process. Therefore, in the high-speed coating process, the smaller the precision error of the surface density of the pole piece and the smaller the thickness error range, the more guaranteed the performance of the pole piece.
This coating machine from Haoneng can stably achieve an area density accuracy of ≤1%, and has high-speed intermittent control technology to achieve small intermittent functions under high-speed coating, thereby improving the accuracy of the length of the pole piece and the thickness of the coating head and tail.
3.High intelligence helps battery intelligent manufacturing
This equipment adopts the world's most advanced technology Siemens Ethernet PLC control system, and adopts the bus control mode to increase the PLC data transmission speed, which makes the equipment run at a much faster speed. In addition, the PLC data transmission accuracy is also greatly improved.
This device can achieve tension control accuracy of ± 1μ, strong automatic deviation correction performance, and can achieve stable transport, no wrinkling, and no deviation during the 6 micron copper foil coating process.
At the same time, the unwinding adopts the non-stop automatic rewinding function, and the automatic rewinding and rewinding success rate is as high as 99%. The AGV automatic conveying, loading and unloading system can realize unmanned equipment operation and continuous operation, and improve production efficiency.
Moreover, its intelligently configured functions such as "online length monitoring system", "online areal density detection system", and "online width and size monitoring system" can automatically detect the quality of coated products from time to time to prevent missed inspections.
4.Efficient drying greatly reduces energy consumption
In the coating process, in addition to the coating accuracy and stability of the coater will have a significant impact on the performance of the pole piece, how the pole piece is dried will also directly affect the quality of the pole piece.
Haoneng's new coating machine has high-efficiency drying technology. The oven has a unique design, and has been optimized in terms of oven piping structure, air chamber structure, diversion structure, air nozzle structure, and exhaust system. And the waste of energy caused by the heat dissipation of the pipeline, improving the heat conversion efficiency, can save at least 15%.
It is worth noting that, in addition to the above product features, Haoneng Technology also has outstanding performance in the installation and debugging accuracy and debugging speed of this equipment. This is based on Haoneng Technology's strong self-processing capabilities of parts and components. The company's ability to control the product design and manufacturing process makes the installation and commissioning of this high-speed wide-width double-layer extrusion coating machine very smooth, and the equipment coating speed and efficiency are guaranteed, thus gaining high recognition from customers.
Cheng Jianjun said that the release of the high-speed wide-width double-layer extrusion coating machine means that from the powder mixing and conveying system to coating, rolling, slitting, rolling slitting integration, secondary slitting, pole cutting, and then In addition to the automatic logistics system for battery drying ovens, Haoneng Technology has all opened up in the field of lithium battery smart equipment.
At present, Haoneng Technology's customers include CATL, ATL, LG Chemical, Samsung, BYD, Lishen, Lixin, Yiwei Lithium, BAK Battery and other well-known domestic and foreign battery companies to establish long-term and in-depth cooperation. The company will provide customers with more competitive system solutions and enhance customer stickiness, further improving the company's market share and competitiveness.
