Title explains it.
What would you look for when looking at a used robot?
Noises? Checks for backlash?
Type of maintenance? Do they have greese zerks, etc. ?
Next round of questions will be about EOAT sources.
Initially, I'll use a suction cup setup.
So, I'm thinking an air line, for a vacuum inducer, a solenoid, and a vacuum switch to verify part attatchment.
It IS standard operatoing procedure to verify part gripping with the EOAT isn't it?
Also, how about de-stacking infeed parts?
Can I approach the top of the stack, and check for contact, (vacuum) and then conditionally advance to the next lower position.
Or should I use a microswitch to verify contact with the top of the stack?
and again, advance to lower positions until I find a part blank to grab?
That seems safer than relying on a counter to Assume the height of the stack...
(What about a partial stack? etc. )
And on the outfeed stacking, simply keep a counter to track which height to drop the successive parts off at?
Thirdly, the machining center will be using a vacuum chuck.
Current thinking is to remove the finished part, close the door, and using a propellor in the spindle, blow off the fixture to remove small chips.
Open the door and let the robot load the next blank.
Not as fast as having two grip stations on the EOAT, but the blowoff of the fixture will be important.
Unless I can really re-think the fixture design, it does hold chips after a manual part cycle, and needs to be cleaned of chips for each part.
The propellor works pretty well, but it is faster to do it manually, at present.
(I don't think the robot should be blowing off the fixture plate, esp. not while holding a blank and a finished part.)
Thanks for any ideas on all of this...
When this is working, I've got more ideas for the future...
