Release Time : 2024-10-23
Laser welding technology has a wide range of applications in the automotive lithium battery industry, especially for Laser Lens Zinc Selenide. Zinc selenide is widely used in high-precision laser processing and detection due to its excellent optical properties (such as high transmittance and infrared characteristics).
1. Sealing and packaging in battery assembly
Laser welding sealing: In the sealing and packaging process of battery cells, the use of laser welding technology can achieve high-quality and efficient welding. Zinc selenide lenses can be used to focus the laser beam and accurately weld the battery shell and end plate to provide high strength and airtightness.
Translucent window material: Zinc selenide, as a transparent laser window material, allows operators to observe the welding process in real time to ensure monitoring and adjustment of welding quality.
2. Optical detection and measurement
Infrared imaging detection: Key quality control links in the lithium battery manufacturing process, such as the detection of internal short circuits, can be achieved through infrared imaging technology. Zinc selenide lenses are used in imaging systems to capture high-temperature hot spots inside the battery due to their excellent infrared transmittance.
Non-destructive testing: By using zinc selenide lenses, non-destructive testing (such as laser speckle detection) is performed on the battery to detect defects and foreign matter in the material layer to ensure battery quality.
3. Laser etching and marking
Laser etching electrode materials: Lithium battery electrode materials need to be finely etched to form complex patterns. Zinc selenide lenses are used to accurately control the laser beam to achieve efficient and high-quality etching to ensure the functional requirements of the electrode.
Serial number and identification: Laser identification work such as equipment serial number and control system logo can be performed through zinc selenide lenses to ensure clear and durable identification.
4. Welding process monitoring
Welding quality monitoring: Infrared cameras using zinc selenide lenses are used to monitor heat distribution and changes during welding, and real-time feedback is provided on any problems in the welding process, such as uneven welds and incomplete fusion.
5. Laser drilling and cutting
Battery separator drilling: In the production process of battery separators, micropores for ion transmission can be formed by laser drilling technology. The use of zinc selenide lenses can accurately control the drilling position and size to improve the performance and safety of batteries.
Fast cutting: In some cases, laser cutting is used to quickly and accurately cut battery materials or structural parts. Zinc selenide lenses can optimize cutting patterns to achieve high precision and efficiency.
6. Environmental adaptability
Harsh environment applications: Considering the particularity of the lithium battery manufacturing environment (such as constant temperature dust-free workshops), the high stability and durability of zinc selenide make it the preferred material for precision manufacturing and testing in high-demand environments.
In the automotive lithium battery industry, Laser Lens Zinc Selenide has important application value, especially in battery assembly and packaging, optical inspection, laser etching and marking, welding process monitoring, laser drilling and cutting, etc.
