Rule 34 (II)

You know a job is fun, when the SO8 chips have an orgy at the vibratory feeder:


Nope, vibratory feeders are not that great. Especially with short chips, wich have the bad habit of flipping in the seat and then get pushed to the wall by the whole chip column (80+ chips).
Here’s how it looks like on the inspection-cam:


Yes, that’s as good as it gets on the small viewport. (keep in mind that machine has 15+ years). At one point I’m going to fiddle with the camera options to get a clearer picture, if possible.

As of the Machinist posts, I am really enjoying this job, altough it has odd working hours, (at least the first six months, I have been told). The good points is that it’s not as boring as some people tried to sell it to me, or at least I don’t find it boring. The bad points is that I have sort-of a coworker, wich altough not being near a pain in the ass as Dumbassy’s, it has the bad habit of lying to me in some sort of trying-to-impress way. He also learns quite slowly (he’s 20+ years older than me) wich gets to my nerves…but that’s life for you.

As for documenting, I haven’t found my go-pro mounts yet, but don’t worry, you haven’t missed anything especially interesting.

Also, my boss let’s me play around, so, can’t complain in that area. I don’t doubt he will allow me to assemble my own boards too. (in my own time, I mean)

I can (hardly) live with that, at least for now.

U hungry?

Reel feeders, what the heck do they have inside?

This is just one type in the feeder world. I will photograph the pneumatic ones when we get to use them.

And, what does a feeder do?

Sorry for the background sound, it’s a portable generator we’re using while the electric company decides wether or not to provide power to our machines.

When the feeder nozzle picks a part, it briefly interrupts an opto switch. Once the interrupt is gone, it advances a piece. It doesn’t actually know what the piece spacing is, you have to program it (via button presses) to set both step and fine tuning the center.
Part centering is only critical as small as the part goes, but not for the machine itself to pick it up, you can adjust pickpoint as you please from the GUI, but if you wander too far, the pick won’t trip the optoswitch, and hence, not advance a part, generating an error (vaccum error I think, will check tomorrow)

The Machinist, episode 1: Sit straight, bitch!

And here we are, finally, some real machinist work.

Once the machines had been positioned using the string guide, it was time to fine tune their alignment. We’re talking about -+0.3mm here, so, not that much really.

One might thought that these kind of machines should have some kind of mechanical link to actually bring them together and make the rails run true, however, nothing is as far from reality as that thought.

Conveyors weigh nothing, so, no help in the not-displacing department (more on that on another post), and a pallet truck for the heavier ones just doesn’t move them absolutely vertically. You have to lift, bump, drop, check repeat. Anyhow, we managed to achieve said required precision…more or less:

We have to ensure angular alginment too, not just belt offset, so we tape two big boards together to have a really long guide, and handling it down the route, you can feel if it snags somewhere, and act acordingly.

It’s fun, it’s satisfying, and above else, it’s not lying in the really cold ground, wrenching alignment over and over again. (we have readied one line only, so I still have ground work to do in the near future.

The Machinist, episode 0.96: Salutations from below.

This is what I’ve been seeing for the last few days.


Yup, nice close-ups from the floor.

All machines must be finely adjusted within 1mm of height (in a descending ramp /destacker-solder paste-pick&place-oven-stacker/) so the boards can ride freely from one to the other.
It’s boring at best, but I get to lie down for a bit while my boss springs up and down checking alignment. XD!

The Machinist, episode 0.90: Bored @ Work

There is a point of boredom, when I just have to do some silly or weird thing…I…just need to let some steam out. (plus, we had to stop working because some workers where installing vents, or electrical conduits or whatever…)

So, this whatsshappened*:

Best part? I did this not notticing that the main engineer was looking at me…when I turned after hitting stop…his face was just “…WTF?!?!?!…”(because well, that’s me menacing to hit a 100.000€ machine with a Stilson wrench.) and I just looked at him to the eye and shrugged a “dare to say something…”

And he didn’t, of course, they already know I’m nuts.

*Yup, that’s the nonexistent word meaning I recorded that for the lulz on my electronics-friends group.
