The purpose of this project is to deliver cost-effective pick and place machines to makers, businesses, laboratories, academic institutions, and others interested in electronics manufacturing. A pick and place machine automates the assembly of electronics by picking up tiny electronic components and placing them on circuit boards.

To get all the latest updates on this project please visit our Hackaday page Hackaday

Our automatic feeders are the biggest differentiator between us and other projects like ours. We laser cut the parts for our feeders locally. We have a demo video of our previous prototype of the feeders here.

Each feeder bus has a master feeder that talks back to the control computer with a USB cable. Each master feeder can be connected to multiple "daughter" feeders through a CAN (Controller Area Network) bus. The CAN bus is what is used in automobiles for reliable communication among all of the electronics in vehicles. The feeders are daisy chained together to establish communication from a feeder, to the master feeder, back to the control computer.

Various parameters stored on the feeder control the actions of the feeders, such as how many steps the stepper motor should take to advance the tape reel, how long the tape retraction motor should run, and so on.



We will release the details for all of this communication in case someone wants to use our feeders with a different machine.

The YouTube video shows placements of 0603 and 0805 passives as well as TSSOP-28 (0.65mm pitch) and TQFP-44 (0.8m pitch) packages. These are not the limits of the machine! It's just what we use. We will upload videos to demonstrate the machine's performance with other packages. If you have a package you're curious about, let us know, or offer to send us a part to try!

In terms of components-per-hour: the average placement speed as shown in the video is 260 components-per-hour. Yes, we know this is on the slow side. This is with full vision processing on every part (worst case scenario). If you line up your parts square with your circuit board and don't need to do rotational vision correction on every part you can currently get closer to 850 components-per-hour.

We should be able to move our speed numbers up substantially before shipping. Our new head will enable this in several ways.

With our current pick up head our computer vision might tell us we need to rotate 3 degrees, then we tell the motor to rotate the part 3 degrees, but then we have to check to see if we actually rotated the part by 3 degrees. We have to check our work because of the backlash between our motor and our suction tube: with the backlash we might not actually rotate the part a full 3 degrees. The new head has zero backlash. So we'll be able to fly over the upward looking camera, grab a snapshot, immediately start on our way to the placement location, and apply the rotational correction as we're dropping the part after the computer vision has operated on the snapshot it took.

The new head will also have the cameras rigidly mounted to it, so we should be able to go faster without the cameras unintentionally moving from the acceleration.

Unfortunately the 3D printed parts are not vacuum tight right after the print. I can breath through the hose mounted to the adaptor ... it means most of the vacuum is left until it comes to the nozzle tip. At the moment liquid rubber on the inside and paint on the outside seales it enough. But it takes time (2x 24h) to get it dried :-(
The printer runs with slight underextrusion to fit inner and outer design geometries (0.5mm nozzle gives a 0.58mm string).

How can I get the parts really airtight without a long-standing postprocessing as described above?]]> lutz_dd Pick-and-Place Electronic Assembly (and robots!)

VisionBot will enable the dream of many makers who want to turn their homemade prototypes into industrial products. For more details access www.visionbot.net

Initially, we were interested in releasing the software open-source for everybody.

I am currently preparing a weekly Pick and Place assembly meeting,
which takes place in Frankfurt - at the 'Gallus-Theater'.

We meet every wednesday, 19.00h.

The goal of the project is to gather Pick & Place knowledge - insights of the underlying technology by rebuilding an existing DIY Pick and Place Project. The chosen Open Source DIY Project is almost finished - and very well documented.
If you are interested in collaborating - contact me or just drop in.

There are lots of DIY pick and place machine around, these tend to be one-offs for private purposes. Some of them very good, but apart from teaser videos on youtube, no detailed plans are available. Machines which have made to market are relatively expensive (e.g. [buildyourcnc.com]). They tend to come from CNC background, so heavy metal, with Mach3 or EMC, bespoke machined components.

I've seen some really simple systems, one guy using Repetier host (http://www.youtube.com/watch?v=emGQ80bTtBs&list=UUPw_8uMdPFrSkW8e4MuBlZQ&index=1) which inspired me to try to build a simple system which re-uses existing reprap technology where possible. We want to use off the shelf components, or printed parts.

There also the OpenPnP project [openpnp.github.io] which I hope will provide some host software.

I think one of the reasons a lot of DIY pick and place projects start but don't finish is they set the goals to high. Trying to reproduce a commercial system and also make it many times cheaper just doesn't work. So for me, keep it simple is the mantra. For hobby uses, one-offs, rapid prototypes we must make compromises to reduce cost. Overall cost I am putting at £500 ($800), i.e. similar price to reprap printer.

First step is to get a X-Y robot going: [attachment 14573 pick_place.png]

This bears some resemblance to Danh Trinh's machine, that is largely coincidental. I was actually trying to blend a Darwin type frame with Mendel X carriage. I did think about providing an add-on for any Reprap printer, this would limit the component feeders to cut strips, since the table moves.

I know as I get deeper into this hobby and get more and more parts laying around, I will definitely be interested in learning how to write simple firmwares for sanguinos and the like to control simple robots.

(1 reply) https://reprap.org/forum/read.php?132,177550,177550#msg-177550
I created some circuit boards using OSH Pool they made the board I made the files in KiCAD.
Some of the gerber layers that can be exported to different formats are the solder paste layer.
so if the smallest cap or resistor is a 805 or 1210 SMT.
Could a solder paste plunger holder and insert to leave the 3mm or 1,7- 1.8 mm hole in a printed plunger the mk6 or mk7 with the nozel unscrewed so the plastic fed out pushed the plunger and made the bot extrude solder paste based on a stl file of the image or 2d extruded to 3d paste pads.
The corner of the board would proably need a jig for the calibration of the TOM to see the board corner as zero.

How hot could the heated bed platform get and could it be used for reflow if the TOM's box was surownded by a pink foam insulation box?

Now here is the last and more difficult trick .... a suction tiny pipe that would pick up the components in long trays and servo or stepper to rotate them and a web cam or something looking down to view the board.

Then after I press the buttons on the control panel to assemble one board put the components down or pick n place could it redo that with a mouse macro like a recording.

If all 3 steps could be done solder paste printed then parts pick n placed then reflow that would be awsome.

How it works:
a small vacuum pump creates suction in the blunt tip needle to pick up SMT components and the gear motor rotates the component into the proper position.

Materials:
6 20 mm M3 cap screws
3 35 mm M3 cap screws
1 10 mm M2 screw, or whatever screw will couple with the shaft on the GM3 gear motor
1 18 gauge blunt tip dispenser needle
1 magnetic rotary encoder and magnet retrofitted GM3 gear motor
1 meter of 4 mm diameter aquarium tubing $0.43
a low vacuum pump, possibly a reversed aquarium air pump

Instructions:
1. connect the part named pnpdisk2 to the motor drive shaft
[attachment 974 pnpdisk2.jpg]
2. stick the 4 mm aquarium tubing into the blunt tip dispenser needle and put this into the part called pnpdisk1
[attachment 972 pnpdisk1.jpg]
3. attach pnpdisk1 to pnpdisk2 with the 20 mm M3 cap screws
4. attach the magnetic rotary encoder to the part called pnpclamp with 20 mm M3 cap screws
[attachment 976 pnpclamp.jpg]
5. attach gear motor to clamp with 35 mm M3 cap screws
6. attach clamp to x carriage]]> Gene Hacker Pick-and-Place Electronic Assembly (and robots!) Wed, 19 Aug 2015 10:01:59 -0400
