Ion Air Jet Keeps Laser Scanner Lens Clean, Eliminates False Reads

An automobile manufacturer was looking for a solution to keep their laser scanner lens clean in their body welding process. The Automatic Guided Vehicles or “AGV’s” are equipped with a laser safety scanner mounted on the front and back of each vehicle, used to detect any foreign objects in it’s travel path. The scanners are fitted with a polycarbonate protective lens and as the vehicles travel through the system, the lens can build up a static charge, attracting airborne dust and particulate, which results in false readings, shutting down the line.

The current cleaning method involves an operator using a microfiber cloth to manually wipe the lenses clean, and while this does work, with the scanners being mounted roughly 4″ above the floor, this poses some ergonomic concerns for their workers. The customer found EXAIR after looking on the internet for static elimination products and it turns out, they are currently using several of our products in their facility, but he was unsure which product would be suit their needs so he reached out for assistance.

After further reviewing the application with the customer, they explained that each vehicle makes several “scheduled” stops along the route and one of these areas would be selected as the install point. I suggested the customer use (2) of our Ion Air Jet Kits, to clean the lenses. The Ion Air Jet produces a high volume of ionized airflow that can be focused right at the lenses to eliminate the static charge and carry the fines away. The kit includes a filter separator which is going to remove any condensate and/or dirt in the air supply, as well as a pressure regulator. The pressure regulator will allow them to easily adjust the supply pressure to control the outlet flow and velocity so they don’t disrupt other areas in the process.

Additionally, I suggested they use (2) of our EFC – Electronic Flow Control, which features a timing controlled (0.10 seconds to 120 hours) photoelectric sensor as a means to control air usage. As the vehicle enters the blow off area, the sensor will “see” the vehicle, signaling the solenoid valve to open the air line to the jet to blow off the lens. As the vehicle then exits the area, the sensor would again send a signal to close the air supply, so compressed air is only used when needed, reducing operating cost and further automating the process.

I Love A Good Commercial

I watch an awful lot of television. I always have. I grew up in the 1970’s, and I can STILL remember the sixth sense that my friends and I seemed to possess, regarding the imminent air time of our favorite shows. We could be engaged in the most epic Friday evening whiffle ball game EVER, but a few minutes before 8pm, we all became acutely aware that The Incredible Hulk was about to come on, followed by The Dukes Of Hazzard. Throughout the week, our games might be called on account of weather or darkness, but on Fridays, they’d be called on account of Lou Ferrigno (The Hulk) and Catherine Bach (Daisy Duke.) It’s entirely likely that this was triggered by the subtle reinforcement of having viewed a short advertisement earlier in the week, shown multiple times, just to make sure it stuck:

For the record, we didn’t watch Dallas an awful lot.  We got sent to bed right about then.  In retrospect, I’m glad.

In the present age of Digital TV and programmable DVR’s, I honestly don’t watch too many shows when they’re actually being aired. And with the fast forward function, I don’t catch too many commercials, except when (much to my wife and sons’ chagrin) I back up to see if I might be interested in. And yes, it’s usually food or vehicle-related. I’m usually in the mood for a cheeseburger, and…don’t tell her…but I may be purchasing a pickup truck very soon.

But I digress. I got to thinking about the effectiveness of commercials when I had the pleasure of discussing a blow off application with a caller recently. He was looking for a way to keep the lens of laser sensors clean…there are three sensors located inside his machine, and they are used to check & control the exact positioning of precision machined parts. As good as they are at doing so, just a little bit of coolant spray on the lens will have a pretty bad effect on their operation. When he started describing the sensor to me, I knew exactly what he was looking for, because I’d seen something just like it in a “commercial”…

OK, a Press Release, actually. Now, this is the Model HP1126SS 1” High Power 316SS Flat Super Air Nozzle, which was needed for the aggressive, high temperature environment in which this photo was taken. He didn’t need all that, so he went with the Model 1126 1” Zinc Aluminum Flat Super Air Nozzle, which has more than enough force & flow to blow off a little coolant mist, and is perfectly suitable for use around water-based solutions.

When I showed it to him, he agreed that it was exactly what he was looking for. I feel bad that I neglected to tell our Marketing folks how easy they made it for me to solve this application until now…but they totally rocked it. Thanks!

Our Application Engineers work with them to publish Press Releases, Newsletters, Case Studies, Application Database entries, and more, on a regular basis. I encourage you to check out our Media Center and Knowledge Base (registration required, but it’s free and easy) to get an idea of the full range of our abilities to solve your compressed air product applications. We can start there, and if you ever have any questions, give us a call. We’re eager to help.
