Detailed introduction for Insulating Glass Automatic Production Process
I. Introduction
Mechanized production of insulating glass significantly improves production efficiency and product quality. This plan details the process of manufacturing insulating glass using automated machinery.
II. Production Process
A. Glass Feeding and Cutting
- Automated Loading: High - speed robotic arms are used to load large sheets of float glass from storage racks onto the glass cutting line. These arms are programmed to handle the glass gently to avoid scratches or breakages.
- Precision Cutting: Computer - controlled glass cutting machines measure and cut the glass according to pre - set dimensions. The cutting blades are automatically adjusted for different glass thicknesses, ensuring a precise cut with an accuracy of ± 0.5mm.
B. Edge Processing
- Grinding and Polishing: The cut glass edges are fed into an automated edge - processing machine. This machine uses rotating abrasive wheels to grind the edges smoothly and then polishes them to enhance the glass's appearance and adhesion for sealants.
- Drilling (if required): For customized insulating glass with holes, a numerically - controlled drilling machine is integrated into the production line. It accurately drills holes based on the input specifications, with a high - speed spindle ensuring clean and precise holes.
C. Washing and Drying
- The Glass will be washed with the glass washing machine.The machine is with 6 soft brushes for cleaning and knieves for drying.It is ok for Low-E glass and the glass thickness can be adjusted automatically.
D. Spacer and Desiccant Handling
- Spacer Bending and Assembly: An automatic spacer bending machine forms aluminum or stainless - steel spacers into the required shapes. The machine can handle different spacer profiles and lengths. Desiccant is automatically filled into the spacers through a precise dosing system to absorb moisture in the air gap.
- Spacer Placement: Robotic arms pick up the bent spacers and accurately position them between the cleaned glass sheets on a conveyor - based assembly platform.
E. Gas Filling (Optional)
- Inert Gas Injection: For insulating glass that requires enhanced thermal performance, an automated gas - filling machine is used. It injects inert gases like argon or krypton into the air gap between the glass panes. The gas flow rate and pressure are precisely controlled to achieve the desired gas concentration.
F. Sealing
- Primary Seal Application: A robotic sealant dispensing arm applies the primary sealant, typically polysulfide, along the inner edge of the spacer. The arm moves at a constant speed and pressure, ensuring an even and consistent sealant layer.
- Secondary Seal Application: After the primary seal has cured to a certain extent, another robotic arm applies the secondary sealant, such as silicone, on the outside of the primary seal. This provides additional protection and strength to the insulating glass unit.
III. Quality Assurance
- In - line Inspection: Throughout the production process, multiple in - line inspection stations are installed. These use sensors and cameras to detect defects such as uneven sealant application, air bubbles, and misaligned components. Defective products are automatically flagged and removed from the production line.
- Final Testing: Before packaging, each insulating glass unit undergoes a final set of tests, including a leak test for gas - filled units and a dimensional accuracy check. Only products that meet the strict quality standards are approved for shipment.
IV. Conclusion
This mechanized production process for insulating glass, with its combination of automated machinery and strict quality control measures, ensures the efficient production of high - quality insulating glass products, meeting the demands of the construction and related industries.
