Loading TM220A pick and place part stacks

IMG_0755-W600

Loading up the pick and place with part reels. We decided to put the most common, cheap stuff in the back of the ‘stack’ of reels. After all, it won’t need to be swapped.

Less used stuff is going towards the front, that way it is easier to swap out. We’re leaving free 8mm reel spots right in the front of the stack, that way it’s easy to temporary load a certain capacitor or resistor value.

Here’s the stack, from front of machine to back:

  1. Free (8mm feeder)
  2. BAS-16J Diode DO-323
  3. 1.5A ferrite bead 0603
  4. 3.3volt regulator SOT-23-5
  5. Yellow LED 0805
  6. 18pF cap 0603
  7. 0.1uF cap 0603
  8. 1uF cap 0603
  9. 10uF cap CASE-A (1206)
  10. 2K resistor 0603
  11. 10K resistor 0603
  12. 10K x 4 resistor array 1206
  13. 5.4mm buttons SMD (12mm feeder)
  14. free (12mm feeder)
  15. free (16mm feeder)

  1. Depends if it is for ‘production’ or prototyping.
    On ‘cheap’ machines, it is better to place the parts in the most logical position for speed
    I.E average out the arm travel distance and place the part to get the highest reduction in distance.
    If you are skillful it can mean more production over a given timeframe based on more ‘logical’ positioning.
    But looking at the construction of the machine, the design of the feeder mechanisms are quite poor.

  2. Hello,

    I’m so glad that you’re presenting this machine. We’re thinking to buy it and would like to know where you get it and for how much / which delivery did you choose?

    Also please post about the problem you had with this machine and about precision this will be so helpfull for us !

    Can’t wait to see a video of the setup and of the placing.

    One more question, what did you add to the machine and where di you got it?

    Thanks !

    1. Are the feeders on this sprocket-driven somehow, or do they use the pickup head to ‘pull’ the strip each time?

      1. I hope we will see this in the video. Considering the price point, i expect to see some mechanism in the head to advance the strips. Having individual actuators for each strip (or having just one actuator in the base with some mechanical contraption to connect it to each strip feeder on demand) would make the device more expensive, i guess. But we will see in the video :)

      2. Update: Just found Xinort’s review… look up the post “$5000 pick and place” here on the DP blog (i totally missed his review until today). As Xinort wrote, the strips are advanced by electromagnets — i was so wrong…

      3. The pickup head has a solenoid with a little finder that pops down into the holes of the SMD tape, then the pickup head moves sideways to load the next part. The spools you see just pickup the plastic foil covering.

      1. If you had a board with say ~20 1206 parts and needed to make a dozen or two a day, would this machine be a viable alternative to hand placement considering no space for a larger machine? (Was considering a zevatech 460, but dont have room.

      2. Are they 20 different parts? Then you need the bigger one TM240A. If just 20 simple parts, maybe, but don’t hold me to it until we get a good workflow going and actually make a few boards.

      3. ~20 parts count. Probably 5 different values. The current version of the board is all PTH, looking to move all the small passives to SMT to save assembly time and keep the larger parts and ICs PTH.

      4. I’m still withholding judgement until I try it a little more, but you may be in the realm of possibilities. If you;re ready to buy one and wire the money to china tomorrow, we have a group buy going out tomorrow.

    2. Hello Handibot,

      This is Haimi from Neoden,original manufacturer of this pnp machine TM220A,TM240A.

      I think you already bought your pnp machine and run it,how do you think about it?If need any support,pls feel free to let us know.

      And as for whom also interested in this pnp machine,can buy directly from us,we are original factory,offer one year warranty and life time after-sales support.

      As for shippment,we cooperate with DHL,enjoy good discount,door to door service,takes about 3- 5 working days to overseas countries.Very convenient for both sides.

      If any question,pls send e-mail to

      haimi@neodentech.com
