Static Eliminator Helps With Video Inspection

Being that many products are now made of plastic, we encounter many more problems with static electricity.  I have a customer that uses a video camera to check instrumentation appliques before assembly into a vehicle cluster.  The video camera would check for quality defects over the lighted details.  It would check for both light spots and dark spots.  The problem that kept occurring was a defect that was detected with a dark spot.  In closer examination, the dark spot was a piece of debris that was sticking to the applique from static attraction.  The plastic polycarbonate sheets can generate large amounts of static as it goes through the conveying process.  Thus, it added additional cost in having an operator to wipe the applique and re-insert them back into the video booth.  The customer called EXAIR to see if we could solve his problem.

In looking at the process, we decided to use the Super Ion Air Knife.  It would be able to accomplish both routines automatically.  The ion bar will neutralize the plastic applique and particles, while the air knife will gently blow the particles off.  With this combination of air knife and ion bar, the Super Ion Air Knife will generate a laminar flow of ionized air to carry debris away.  This air curtain can keep the applique clean before it goes into the video booth.  We were able to eliminate the “false” rejects, and the operator was able to continue checking the “positive” rejects for quality control.

Like with video inspections, you can use this ionized air curtain to keep plastic parts clean.  Other applications that use this process are circuit boards (or any product during packaging) before they are stored in bags and plastic components being stored in an enclosed storage bin.  With the Super Ion Air Knife, you can make sure your parts are clean from those little charged dirt particles.  As with any of our products, you can always talk to an Application Engineer here at EXAIR.

Plastic Bag Manufacturer With a Climbing Static Problem

A few months ago I received a call from Medipak.  After discussing their application they were kind enough to take advantage of our giveaway (Link Here) by sending us some pictures and an explanation of their application utilizing our Super Ion Air Knives.   Medipak manufactures special UVLI bags that are processed on a machine that was designed to do so.   These bags start on a roll then they are pulled through a machine which cuts and sorts them.  A picture of the machine is below.

The problem Medipak experienced was the feed would lose tension which would allow the bag to start to climb up the curtain which applied tension to the feed.  This would cause considerable amounts of downtime as it was happening quite frequently.   After discussing the application, the customer sent these pictures of the problem he was seeing.   Note the system had a “Static Eliminator” on the cutting end of the machine that would not help with any of the problems he was actually seeing.

Another issue they encountered was when the machine would start to really build up a static charge the bag lengths would start to become erratic and out of spec.

The solution to these issues was to install a Super Ion Air Knife.  The unit mounted quite easily utilizing our Universal Air Knife Mounting System.

Medipak has since seen the bulk material climbing the tension curtain come to a halt along with the problem at the cutting end because the Super Ion Air Knife eliminated all issues with the bag feeding errors and incorrect cutting.

If you’ve had an experience like this customer feel free to send us pictures, video, or even a well written description of your application and you’ll be entered into our giveaway.
