ACUITY’S LINE OF LASER SENSORS

Schmitt Industries, Inc. has been providing process measurement and control systems for many years. In 1992, Acuity Laser was founded to develop a more specific product line of lasers for the industrial and OEM use. With hundreds of applications for our line of lasers, Acuity is proud to be a United States laser sensor company.

ACUITY’S 2D LASER SCANNERS FOR NON-CONTACT LASER SCANNING

Our line of 2D Laser Line Scanners are ideal for industrial parts scanning. We work with companies across the globe to provide the latest in laser technology. When it comes to the use of our 2D scanners, the AccuProfile™ 820 Laser Scanner is a high-accuracy sensor that combines the technology of machine vision and displacement measurement.

ACCURACY IN WELDING WITH 2D SCANNERS

The process of welding requires extreme caution and extreme accuracy. When dealing with high temperatures and melting of metals, there is little room for error. Many manufacturers have chosen to use Acuity’s 2D Laser Scanner to inspect the welding process.

MEASURING DISTANCE TO HELICOPTER LANDING PADS

When pilots are preparing to land a helicopter, they rely on the accurate and high performance of distance sensors. These distance measurement sensors will help pilots gauge the distance to a landing pad for a safe and timely landing.

MEASURING RAIL GAUGE USING LASER SCANNERS

In order to keep commerce moving, railroad companies as well as shippers, rely on inspections and preventative maintenance to keep trains moving safely. Train rails are regularly inspected for defects and one of the criteria for train rail inspections is rail gauge. In the United States, the standard rail gauge is 56.5 inches and it is important that rails do not get closer than 56 inches or further than 58 inches.

PROFILING TRANSLUCENT GLUE BEAD USING A LASER SCANNER

Laser Scanners are quickly becoming the tool of choice because they merge the benefits of camera vision systems with the precision measurement of non-contact laser distance sensors. Today’s laser scanner technology is leveraged for quick and accurate quality control applications of precision parts. For example, laser scanners are used to verify weld joints for ample filler metal and gaps. Similarly, engineers choose laser scanners to follow pneumatic sealant or glue dispensers to verify bead presence and dimensions. While glue beads can be challenging to optical sensors because of their shiny (when wet) appearance, translucent gels can be particularly challenging because the laser light typically penetrates the surface to measure the substrate material. Only the most sensitive scanners can adjust lighting and detector integration quickly and automatically to measure translucent / transparent surfaces.

3D LASER SCAN OF KEY

Demonstrating the capabilities of the new AccuProfile 820 Laser Scanner at the recent Quality Expo (Chicago), operators scanned an individual car key to produce an elevation map. The AP820 laser scanner emits a laser line onto a surface or object. The image of this line is viewed by a high-accuracy CCD array. Height positions are calculated across this line and transmitted over an Ethernet line to a PC computer.

LASER PROFILE SCANNING OF VALVE BASE

In this application, engineers tested the Acuity AP620-7 laser line sensor to make dimensional profiles of a small polymer part used in an industrial applications. Currently, the company uses calipers and comparators to measure this part. The area to be measured is a diameter at the circumferential “shoulder” formed by the floor of the part and an interior wall. Proper detection of the joint between the 30° wall and the horizontal surface was very important. Additionally, it was critical to align the laser line with the diameter of the circular part and not a chord. Any misalignment would result in a shorter diameter measurement. Engineers suggested scanning the part as it passed beneath the scan line and then capturing several cross-sectional frames. Software algorithms could be used to determine the maximum dimension of all collected and this number would be the diameter.
