100% in-line quality control solution with off-the shelf standard product, Easy to setup, excellent repeatability, flexibility and control of position and force (Soft-Land capability). Long life and robust product.

1. Applications in
Automotive Glass
The ability to do work and verify its accuracy at the same time

2. Applications with Automotive Glass
• Glass Cutting
• Inspection of the Curvature of Window Glass
for cars, trucks and airplanes.
• Positioning Car Glass Windscreen for Grinding process
• Measuring thin material (Flexible glass)
• Glass Grinding
• Profile measurement of a glass surface.
• Measure Height & Width of grooves on a machined part plate
• measurement of glass windows. These are the double pain windows
that have the shutters inside of them. The task is to monitor (Measure)
the distance of the glass panes in three opposing locations
• They make soldering station for soldering wire on tempered glass. He
wants to use the unit in conjunction with air cylinders to follow the melt
of the solder.

5. The Leading US Glass Manufacturer
Application 1
• Glass Cutting Machine
4 LAS95-015 with 4 LAD-1 and cables are used to
cut the glass using position and force control.

6. Glass Grinding
The grinding process produces a 125 µm finish with
less than a 50 µm variation in the finish.
LAL-55
LAC-1 One Axis Controller
LAH-LOD-03
Glass Panel
Problem: Damage to glass at beginning and end of grind cycle caused by
inadequate force control of the air cylinder driving the grind wheel.
Force Required 2-4 Newtons
Stroke: 5 mm.
Solution: Customer was able to soft land on glass and provide a constant
force through the force mode of the LAL-55 at both the beginning and end
of stroke as noted in the diagram below:

Application 3
Measuring thickness of thin material
(Flexible glass)
Problem: Accuracy of current air cylinder, LVDT and force control system.
Solution: Customer used the soft land feature of the of the SMAC LAL-
20, in conjunction with a load cell mounted on the rod of the LAL-20. The
LAL-20 is controlled by a Dual Axis LAC-25 as noted in the below sketch.

The 2 pneumatic cylinders for centering the windscreen are replaced by the 2 LAL95-015.
Two of six pneumatic cylinders for position measurement are not needed anymore.
The LAL95 provides both positioning & measurement.
All other sensors, mechanical and electronic parts are unchanged.
