I'm building a pick and place machine. I hope to be able to use thishttp://garage-shoppe.com/wordpress/?p=109
to create enough vacuum to lift 1206 sized components (to begin with...hopefully eventually larger chips).
I hope to be able to place 10-20 parts per minute so I need to turn the vacuum on and off up to 40 times per minute. I could control the pump directly with a relay, but that seems like startup/shutdown would waste several seconds, and switching on and off so often would wear the pump out quickly. Or am I guessing wrong?
Therefore I think I need a pneumatic solenoid valve, and control that with an IO pin and a transistor. If so can anyone tell me if this is a suitable onehttp://www.ebay.com/itm/DC-24V-1-2-2-Way-Electric-Pneumatic-Air-Solenoid-Valve-/320874215826?_trksid=p3284.m263&_trkparms=algo%3DSIC%26its%3DI%26itu%3DUCI%252BIA%252BUA%252BFICS%252BUFI%26otn%3D21%26pmod%3D270949264800%26ps%3D54#ht_1675wt_974
This is just the cheapest one I've found. I'll be using 1/4" silicon hose to connect the pump to the pick up head so ideally I'd like a valve with such fittings so I won't need a bunch of adapters. If anyone has any recommendations on such a valve I'd appreciate it.
Thanks as always.
