LED LCD Panel

High Precision Linear Motor Drive Solution|Enabling LCD Panel Manufacturing Yield to Surpass 99.5%

 

Linear motor-driven LCD panel handling/cutting/dispensing equipment working panorama + close-up of motor module

 

Linear Motor Core Value Matrix 

1. Nanoscale positioning accuracy 
Repeat positioning accuracy of ±0.5μm (to meet the needs of OLED vapor deposition process) 
Grating scale closed-loop control, eliminating backlash/crawling phenomenon 
2. Ultra-high-speed dynamic response 
Peak acceleration up to 5G, response time <10ms 
Supports S-shaped speed curve planning, vibration amplitude reduced by 70%. 
3. Zero contact and maintenance free 
Mechanical frictionless structure, life time >100,000 hours 
Cleanroom compatible (ISO Class 3 certified, no oil emissions)

 

Four application scenarios of linear motors in LCD manufacturing 
Scenario 1: Precision handling of glass substrates 
Maximum load 1200kg, speed 2m/s 
Magnetic levitation technology realizes ±1mm levitation height control.


Scene 2: Panel cutting and positioning system 
0.1μm micro-step control, 3 times longer life of cutting wheel. 
Real-time compensation of thermal deformation with laser interferometer


Scene 3: High-speed lamination of optical film 
300mm×300mm stroke repeatability ±1μm 
Dual-drive synchronized control, deflection angle <0.001°.


Scene 4: Defect detection scanning 
600 times/min high frequency reciprocating motion 
Low cogging force design (thrust fluctuation <0.5%)
