Client: Truck Manufacturer
Project: Front Laminated Glass (Windscreen) Bonding Application in Trucks Cabin
Plant: Pithampur, Madhya Pradesh
Truck Manufacturer was previously using a manual process for applying sealant to the front laminated glass of their truck cabins. This traditional method, which used a 1K sealer component, was time-consuming and less efficient. To improve strength, quality, and turnaround time, they decided to introduce a 2K component material.
Implementation
The added activator in the 2K component increased curing speed, improving the process cycle. This new sealant application system, developed by Patvin, was the first of its kind introduced for the client in India. The system included advanced robotic integration, material handling, and process parameters specifically tailored to clients requirements.
Discussions with Supplier ensured proper material handling, mixing, and process parameter guidelines. Key findings indicated that the material viscosity was higher compared to traditional materials, necessitating a temperature conditioning system and specific piping lengths. Patvin designed a 2K dosing system using two different dozers controlled by a servo mechanism. For the first time, Patvin provided a KUKA robot and an integrated turnkey solution for the glass gluing system in the assembly section.
Customized Glass Bonding Solution Components
- Adhesive Feeding Pump: Equipped with a 200-liter changeover system and conditioning.
- Booster Feed Pump: Moisture isolated.
- Servo Driven Dozers: 600 CC for adhesive (A) and 30 CC for adhesive (B).
- Hose Bundle, Valve Module, Disposable 2K High Viscosity Mixer, Triangular Bead Nozzle.
- KUKA Robot (KR-30), Robotic Fixtures, Base Structure.
- Laser Profile Scanner, Central Controller for Sealant System, Cable Package, Nozzle Cleaning Station, Barcode Scanner, Safety System, Primer Shaker x 2 Nos.
The system was manufactured and tested at Patvin’s facility, followed by customer inspections. Upon satisfying the client’s expectations, the system was dispatched for site installation.
Results
The new robotic sealant application system met all RFQ expectations, resulting in less material waste compared to the manual process. The use of new materials and an entirely new solution by Patvin demonstrated their capability to innovate and provide integrated solutions for the first time globally in windshield pasting.
