The safety performance of the power lithium battery is undoubtedly one of the most cores to solve during the development of new energy vehicles.. Recently, a debate on the “safety” of the industry has triggered a wide range of attention in the industry, and the safety problem is that the problem of the power lithium battery industry urgently needs to be solved and has received extensive attention.
. During the manufacturing process of the power lithium battery, the glitch of the ears and the sealing of the battery are undoubtedly important factors affecting their safety performance..
It is well known that the eurotype and the electrical core internal dust is easy to pierce the diaphragm, which causes the electrical short circuit; the sealing of the battery also affects battery safety; in addition, from the PACK level, the battery soft connecting piece also affects the battery. Safety. Therefore, the cutting of the ears and the welding and battery connection effect of the electrical cylinder are particularly important.
. As the leading high-end intelligent equipment and factory automation solution supplier, Li Yuanheng has an excellent technical team consisting of many Hesheng Ph.D.
and a number of masters, regardless of the core technology of independent development or the advanced technology of foreign laser laboratories. , Covering laser technology and application, precision optical design, sports control, visual and software control, etc., is committed to meeting new energy, semiconductor, automotive components, precision electronics, medical, rail transactions, etc.
One-stop laser application overall solution. Relying on the advantages of the company in the field of high-end intelligent equipment and factory automation, laser processing applications in the field of professionals in the field, in terms of laser welding, precision cutting, laser marking and cleaning technological research and equipment development have very prominent performance. Laser processing applications such as new energy lithium-ion battery laser welding, extreme ear laser cutting, digital battery precision welding, have realized mass production of automation equipment.
Laser Surface has a number of core technologies in the laser field, including location synchronous output laser welding technology, and take the lead in successful application of the power lithium battery top cover sealing and welding; high-speed extreme ear laser cutting system to achieve advanced level of industry. Since developing, Li Yuanheng laser has more than 100 authoritative patents, including more than 50 invention patents..
In order to further enhance the safety performance of the power lithium battery, Y Yuan Henzid launched a laser extreme ear cutting machine, power lithium battery top cover sealing welding machine, top cover soft connection laser welding machine, power lithium battery top cover pre-point welding machine, etc. Series laser products. Laser welding technology, Laser welding technology, can solve the problem of non-uniform weld projections during the welding process of the lithium-ion battery top cover, and achieve the stability of welding speed in 200mm / s The top cover welding peripherals, reaching the industry’s advanced level.
According to Yan Yuanheng, the PSO laser welding technology characteristics of Li Yuanhe’s PSO laser welding technology is: 1. By receiving the current position of the welding head feedback of the encoder, it is judged whether or not the current position reaches the set position; 2. When the solder joint reaches the set position, the laser control signal is transmitted to the laser to control the laser in the set position output laser; 3.
Achieve acceleration, deceleration, and uniform welding segments, or uniform use of laser energy in linear welding sections and arc angular welding segments, so that the overall weld is uniform. Lee Yuanheng according to PSO laser welding technology, launched a power-lithium battery top cover sealing welding machine, a top cover soft connection laser welding machine, powered lithium battery top cover pre-point welding machine. Its top cover welding machine can maximize the sealing of the battery, which helps to improve the safety performance and calendar life of the battery, and the soft connection laser welding machine maximizes the occurrence of solder welding, which helps to improve the battery system.
Safety and reliability. Power lithium battery top cover pre-point welding machine power lithium battery top cover sealing welding machine top cover soft connection laser welding machine Length Heng high-speed ultrasound laser cutting system, achieving advanced levels; it has the following highlights: 1. Anti-shake and dust removal design of the overall optimized cutting station.
The control system and process parameters are highly integrated, cut trajectories, and cutting parameters can be flexible and optimized. The encoder count driver, realizes the laser energy, the frequency of the frequency to the trip speed, optimizes the segment of the segment of the segment 4. Ding track cutting, high dimensional precision, good cut quality, glitch and melted beads ≤ 7 μm 5.
Two / four sets of laser systems achieve double / four-sided extreme ear while cutting, efficiency is as high as 120 m / min6. Supports various shape sizes of ear cuts to meet customer needs and achieve one-click change. The profitter of the Liyuan Heng laser extract is here, and the profit of the Laser Pathfinder in the profit, there is a small amount of stress, less dust, high level of automation, and its own dust removal design, boost lithium battery to improve safety performance.
In addition, the Laser Laser Series products also have high work efficiency and good stability.. Also worth mentioning, July 1st – four days, Li Yuanheng will participate in the “SIA 2018” Automatic Industrial Industry Socoon and Industrial Robot Exhibition “, Hall E01 in the Shanghai National Convention Center, E01 Laser technology related products.
