He uses a rubber pad next to the nozzle to advance the tape by friction. Something like a weight applies tension on the cover tape (not shown in videos.) Then, the vision system identifies the first part on the tape so the nozzle can pick it up. When the pad is advancing the tape, the nozzle drops into the space between tapes.
Yes, funny he'd leave those big red errors on the screen for a video! He sells a kit for this machine on his web site. I'd really be interested in how he deals with error handling. I get a fair number of mis-picks on my $100K Philips CSM84. It has 3 different nozzles in 3 heads with alignment jaws currently on two of those, and no vision. Maybe with the vision there are a lot fewer errors. But, the pain with restarting a program on LinuxCNC now would make a LinuxCNC P&P a real nightmare. The CSM84 recovers automatically from up to 4 pickup errors before calling for help. There are certain parts that give me fits due to variations in cover tape adhesion, tape thickness and funny shaped parts that don't pick up or align properly on the jaws. Also, my CSM84 runs at about 3600 PPH on most parts, only slowing down when it has to take the large chips over to the mechanical alignment station. I don't know what the speed of this machine is, but it looks like a bit better than 600 PPH. I could live with one that slow, but I wouldn't be happy.
