DIY – Super-cheap pick-and-place device with ~1 mil accuracy

Well, after some distractions (a small contract for NASA, and struggling to learn solidworks (AARG)), I got back to designing this device, made major configuration changes to simplify, improve reliability and improve precision, and have almost finished now. Reasonable CNC quotes permitting, I’ll have someone start making 2 or 3 prototypes in two or three weeks. So, last chance to add your two cents (or $64,000 worth) of ideas, and point out my worst ideas and design flaws.

I will attempt to post some photos here, and attempt to attach a PDF document that describes how it works. This is identical in principle to the original steps I outlined at the start of this thread months ago, but the configuration of the device has changed so the exact nature of many steps is somewhat different.

Sorry, but you’re probably going to need to maximize your window to see the images. If you’re willing to make a serious effort to critique the design, ask me for the solidworks 2010 files.

I usually think up really great, elegant names for things. This time I’m a total failure (!please help!), so the device is called “papec” for now (pick-and-place extra cheap). Sheesh.

  1. I have this machine, http://bit.ly/mtNgxz It uses a lightweight translation frame and linear encoders, mainly for accuracy and speed. Is the tray table going to move? The L60′s deck is fairly heavy, mainly to reduce vibration. I will read the precis.

  2. how cheap is extra cheap?

  3. Cool captcha!

  4. The roller bearing looks like it came out of an AR-22 TV rotor.
    Actually he probably only showed some of the ball bearings if all were installed then it looks like the bearing of a HAM-M.

    If the track is machined evenly and with the right width it will be a very smooth motion. Don’t know what kind of lube would be best, probably a thin grease.

Sorry, the comment form is closed at this time.
