🚀 High-Speed Precision Glass Printing: Windshield Screen Printing Line Case Study
Welcome to a technical deep dive into the Windshield Screen Printing Line, a state-of-the-art automated glass printing and drying line. Engineered for high-throughput environments, this layout specializes in handling large-format, ultra-thin glass (down to 1.6 mm) with a blistering 12.5-second cycle time.
From pit-free accumulation to servo-driven precision printing, this video explores how the Glassline GHS series sets the benchmark for modern glass fabrication.
🛠️ System Overview & Specifications:
The Windshield Screen Printing Line is designed for Long Edge Leading (LEL) flow, optimizing floor space and processing speed for rectangular glass sheets.
Glass Thickness: 1.6 mm to 3.0 mm
Max Glass Size: 1,400 mm x 2,000 mm
Cycle Time: 12.5 seconds (at dryer exit for max size @ 2.2 mm)
Repeatability: ± 0.2 mm (Cp ＞ 1.33)
Changeover Time: 10–15 minutes (with video alignment aid)
🔍 Key Components of the Line
1. PIT-FREE Accumulators Design: 20-level FILO (First In, Last Out) configuration.
Advantage: “Pit-free” design allows for easier installation without specialized floor excavations.
2. GHS151-T Screen Printing Machine Precision Centering: 3-axis auto-centering with Teflon bars and torque limiters.
Walking Beam Shuttle: Dual-station transport with suction cups for simultaneous pick-and-place.
Servo Technology: Patent-pending 4-corner servo system for precise up/down movement, enabling recipe-driven “off-contact” and “peel-off” settings.
Maintenance: Easy screen extraction and pneumatic squeegee locking for rapid cleaning and swaps.
3. GHS300 / 2000 IR Dryer Heating: (2) modular zones with 18 medium-wave IR lamps.
Control: PID loop control for exhaust dampers and individual lamp selection to maintain consistent wavelengths.
Cooling: (3) modules utilizing high-volume blowers for forced ambient air circulation.
Access: “Clam-style” screw-jack lifting for easy maintenance access.
4. Inspection & Transfer Includes: a 3-way transfer conveyor and a Tilting Inspection Table with an integrated light box for immediate quality control.
🌟 Advanced Options Featured
6-Axis Independent Centering: Servo-controlled positioning for every locator axis.
Laser Radar Screen Break Detection: Real-time scanning to detect ink dripping or mesh failure.
X-Y Vacuum Suction: Specialized system for Print-to-Edge applications, ensuring clean edges even at high speeds.
Corner Break Detection: Optical fiber sensors to verify glass integrity before the print cycle begins.
