Core application of laser cutting machine in glass photoelectric encoder manufacturing

(Click 44 )

As the core component of high-precision angle sensor, the processing quality of the transparent grid of glass photoelectric encoder directly affects the measurement accuracy and signal stability. Laser cutting technology breaks through the bottleneck of traditional processes with its non-contact and ultra-precision processing characteristics, and provides key support for photoelectric encoders, aerospace navigation, medical robots and other fields.

Traditional mechanical cutting causes edge fragmentation and causes light path scattering; chemical etching is inefficient and pollutes the environment. Laser cutting achieves “cold processing” through ultra-fast pulses (picosecond/femtosecond level), the heat-affected zone is less than 5μm, the cut is smooth and burr-free, and the uniformity of light transmission of the code disk is guaranteed.

The laser cutting machine can process ultra-high density grids with a position accuracy of sub-micron level, which meets the angle resolution requirements of nano-positioning systems and improves the accuracy by 20 times compared with traditional processes.

1. Industrial high-precision encoders
In scenarios such as servo motors and robotic arm joints, laser-cut glass code disks support 0.001° angle feedback to ensure the motion control accuracy of industrial automation equipment.

2. Extreme environment sensing system
Spacecraft gyroscopes and nuclear power plant monitoring equipment require radiation-resistant and high-temperature resistant code disks. The light transmittance attenuation rate of laser-processed quartz glass components under high temperature and radiation is close to zero, ensuring long-term reliability.

3. Miniaturized medical equipment
Surgical robot joints and endoscope rotation mechanisms use Φ5mm ultra-micro code disks. Laser cutting machines etch micron-level gratings on their surfaces to achieve precise angle sensing and help precise minimally invasive surgery.

4. Quantum and optical frontiers
Femtosecond laser cutting machines process nano-grating structures on microcrystalline glass, providing a basis for optical path control for quantum gyroscopes and photonic chips, and promoting the development of high-sensitivity measurement technology.

Laser cutting machines reshape the manufacturing paradigm of glass photoelectric code disks. Its penetration from industrial encoding to quantum sensing marks the entry of precision optical components into the “zero damage, nano-” era. With the deep integration of ultrafast lasers and intelligent control systems, glass code disks will be upgraded from passive measurement elements to active photon carriers, releasing greater potential in intelligent equipment, space exploration, and life sciences.
