Eliminating False Image Readings Using The Gen4 Stay Set Ion Air Jet

I was recently contacted by a medical device manufacturer who was interested in implementing a Static Eliminator in their production process. They have a manually operated vision station where a plastic substrate, about the same size as a credit card, is placed into a nest then a small amount of liquid is deposited onto the surface. An operator takes a picture of the liquid and substrate and the image is analyzed. The part is stationary in the nest until the image is taken.  When the station is done, the plastic part is manually removed from the nest.

After some internal testing, they determined that static build up on the plastic part was causing the liquid to move, or “bounce” as they placed it, which was leading to a significant drop in their manufacturing yield due to faulty readings. The cycle time from taking the initial  image and the analysis results is roughly 2 seconds so they were needing something that would quickly remove the charge on the plastic part.

The customer was able to email some photos and after further review, EXAIR recommended they use our Gen4 Stay Set Ion Air Jet in the process. The Gen4 Ion Air Jet is a compact ionizer delivering a quiet, focused ionized air stream to quickly eliminate the static charge on the surface of a material or object. Operating at 20 PSIG, the Gen4 Ion Air Jet is capable of dissipating a 5kV charge in 0.45 seconds while maintaining a low sound level of only 67 dBA. The Ion Air Jet entrains ambient air at a rate of 5:1 and the airflow can be adjusted from a “blast” to a “breeze” simply by increasing or decreasing the inlet pressure. The Gen4 Stay Set Ion Air Jet includes our 12” Stay Set Hose which holds position until it is physically repositioned and a magnetic base for easy installation.

If you have an application that requires a concentrated, ionized airflow or for help with selecting the best product to fit your need, give me call at 800-903-9247 for assistance.

EXAIR Vortex Tube Cools Control Board Inside a Camera Housing

An EXAIR Vortex Tube supplying cold air into a camera lens housing.

An application we see from time to time involves the cooling of camera lenses as they “watch” for various materials in automated processes.  The process usually involves some sort of part detection, checking object specifics for adherence to quality standards, or searching for items in need of rejection.  These process are often fully automated, requiring the camera to process a continuous stream of information and to be housed in the same environment as the materials being monitored.

At a waste sorting facility in France, an end user was experiencing an overheating of their camera.  The result of the overheating condition was unwanted downtime while the internal camera electronics cooled and could not be used.  This meant that an expensive, complex, and efficient piece of equipment was out of service, creating a bottleneck in the waste sorting process.

To solve this overheating condition, the end user worked through the EXAIR distributor in France, Kermaz Pneumatic, to find a solution with an EXAIR Vortex Tube.  The Vortex Tube was installed so that cold air was created and supplied directly into the camera lens housing.  The end result was a reduction in heat at the camera lens, allowing the machine to function at full capacity without stoppage, effectively removing the process bottleneck.

If you have a similar application and think EXAIR may be able to help, contact an EXAIR Application Engineer.
