Launching screws through washers - 3d printed automation

[@DragongeekAndCo]

Now, add rifling to the tube so that the screw spins and have it drop nuts instead of washers, so that the screws directly thread on ;)

[@christopherhelmke]

was thinking the exact same thing ..

[@tareksma1]

he can do both, insert the screw into the washer and then in a second stage it thread into the nut, double insert and double chalenge 😉😃

FN Herstal solved this exact problem in the 90's with the design of the magazine for the P90. they use a carousel chute that leaves no space as all for the item to rotate; the chute changes the orientation.

[@raw_000]

Yeah, seeing screw bounce on the slope, I wondered if a simple S curve would have helped enough to force the tail down the tube first.

[@BallisticTech]

I feel like I must be missing some design criteria that necessitated the part being free dropped instead of rolled/guided with a more contained path...?

[@thewolfin]

@@BallisticTech Gravity is free? Not sure either. I kinda figured he would cut a slot in the tubing that the magazine would fit around, but that would leave a lot of air escaping, and probably jostle around the remaining ammo...

[@ErikLevholt]

But why does it have to freefall such a long way? Just because gravity is free? The first redesign would have worked much better if they was dropped minimum distance instead

[@danamoroso-xjq]

@@ErikLevholt i think that might be because the component that releases the screews from the magazine one at a time is circular, so the screws pretty much need to fall for at least 1r of that component.

HOLEY SHOT! That opening shot was insanely cool!

[@kylek29]

That magazine is satisfying and a smart reuse of off-the-shelf components when needed. For inspiration, you may want to watch old Factory Made or How It's Made episodes, you'll get a lot of ideas on how manufacturers work through similar issues. 11:48 - You may have noticed this, but your parametric design has the screw holes un-constrained, so they end up overlapping the O-rings in some configurations.

[@Freaktor5000]

Richtig cooles ding. Ich arbeite selbst in der instandhaltung bei einem Automobilzulieferer und hab viel mit solchen dingen zu tun. Da muss die schraube immer richtig fallen.

[@michaelmaguire4147]

Why are you giving them that much room to fall and generate energy for the bounce? couldn't you just make the chamber shorter (height-wise)?

[@thingsmymacdoes]

probably because of the mechanism that retains the next screw

[@ViniciusMiguel1988]

First thing that I thought as well, it definitely can be made shorter

[@Chris-14all]

I thought IT would be better to have a Magazin which ist more narrow. The screw slides down with its head on the right wall of the Magazin and has a lot of place to Touch down on the beveled bottom and much more to the left when IT Starts to rotate. My Idea was to have the Magazin smaller so that the place to rotate is gone. So a simple 'insert' of an rectangulare placeholder would reduce the space in the Magazine and the screw would fall down more over the Outlet. What do you think ?

[@HighFlyer96]

@@thingsmymacdoes But the thing is, there is just empty space. You don't see any mechanism in this area moving or sitting. I rather think it's accessability, but considering how critical of a cause of error this uncontrolled bounce is, it's better to sacrifice anything to ensure the control of the process.

[@markrainford1219]

Then it wouldn't be big enough for larger screws.

[@sanches2]

[@mikebonello7494]

As a fellow engineer, i'd say "Bravo" - that this is brilliant!

[@drfrev]

I feel like the first design would have worked if instead of a straight ramp it was a convex ramp. If the ramp was convex the tail of the screw would hit the ramp surface and stop the screw from over-rotating on bounce.

[@The_Horny_Ghost]

I had the same idea too, but the first thing that came to my mind was to limit the freefall where it can spin, from the sides. If designed to a specific thread diam, make it as narrow for the threaded part as can move freely. Drops free, but the head is limited not to flip over. The head diam doesn't matter so much as long as it's bigger than the threads space. Gravity feeds it thread first, unless it somehow makes a backflip, and in that the ramping might help!

[@Doragon613]

or just slanted the opening, to limit the amount of bounce it could have. (kind of like a zig zag instead of a triangle)

[@christopherhelmke]

Thank you! Aarggg i was waiting for this comment. I understand that you are confused. The parts at 11:20 are welding studs that are welded head first onto metalsheets. So head first is correct (only for these parts). I also realized while editing that this is confusing as hell. I had tested them for a potential customer and filmed them in the meantime and just used the footage.. was explaining that in the video, but had to cut it out for "flow" reasons

Junge junge, dachte schon es kommt nichts mehr! Top Video!

[@maxsuica6144]

I wonder if an optical inspection phase coupled with a pneumatic or mechanical gating phase could help get the defects down to about 1:100,000. This defect rate would allow for a run of 1000 parts to have a 99% chance of being defect free - definitely a boon for the operator! So far, I am thinking of an active system based on computer vision, with either an air jet or sliding block diverter. Sensors: The system has two sensors: - Upstream from the diverter, a 1d lidar sensor and computer vision kernel scans the bolt profile and provides a go/no-go signal - Close to the diverter, we have laser gates to verify part arrival and velocity, and trigger state changes - We learn the go/no-go transform offline: - By simulating the bolt's optical profile using its cad data - Or by running the part through the sensor to learn its profile Sliding Block Diverter: In a mechanical diverter, the tube feeds into a spring loaded diverter block. - If the part is flipped, a solenoid shifts the block so that the part enters a tube to the "reject bucket". - Otherwise, it shoots through the diverter block. - A sliding o-ring seal between the shunt block and outgoing tube seals minimizes pressure drop Jet Diverter: In a pneumatic diverter, the tube feeds into a section with an ejection slot. - During normal operation, the bolt shots past the ejection slot, pulled by the vacuum of a second accelerator. - If the bolt is defective, an air jet knocks it into the reject bucket. - If the reject bucket is sealed and maintained at line pressure, the second accelerator may be unnecessary. All this amounts to incredible bike shedding if we can't carefully model the reliability of the sensor and diverter, and persuade ourselves that this scales to 1:100,000 defect rates. I'll see if I can find a paper that lets us do some helpful napkin math here.

If you are using after effects for the diagram, you can go to layer > transform > orientation > oriente along path. Then you can draw a path copy and paste in position and the screw will curve automatically with the path. Making the bends of the tube etc.

Great video, as always! Thank you for sharing your progress it is such a pleasure to watch!

[@seabeepirate]

I enjoy the opportunity to watch another creative’s process, thanks! I think that your previous design could also work with a parametric change. An asymmetrical v shape with a small bumper on the head side and a curve for the tail side to spin with a width at the top of the v that is slightly wider than the hardware you’re sorting is long. A claw or fang shape if that makes sense. The head will cause the hardware to spin when it hits the bumper and then the narrowing shape will prevent it from over rotating. The width of the funnel as well as the curves would depend on the length of the hardware but that’s just a little bit of math and the computer does the hard work.

[@Forcelord50]

Oh hell yeah, another Christopher Helmke video. It's been 6 months?!

[@Odins-Dad]

This is absolutely awesome! I've been watching and waiting for you to post, but I don't remember all the specifics, so feel free to ignore my suggestion if it doesn't fit your project plan or you're already doing something similar. I also don't have a ton of experience with automated systems so I could be way off. I think it's already very marketable as a manual system, but I think what you need to really make this more widely marketable is software to control it all and update a database automatically. Or even have it be controllable from work orders from ERP systems. Like having 3 levels of available systems. Level 1 would be fully "manually" controlled where you choose how many of each from the control panel and it doesn't do any tracking. Level 2 would be controlled by some simple software that keeps and works off it's own database. And Level 3 (Where the BIG money would be) is a system that can take work orders from popular ERP systems and auto-update inventory levels. Level 3 would probably require some consulting work for install and integrating it with the customers process, but that's where the big company's would most likely be based on what I know about manufacturing. Medium and small companies would probably get by with a level 1 or 2 system or figure out the integration themselves if they purchased a level 3. The programming to hook everything together to a single controller might be pretty simple like WS2812b individually addressable LED's?..... maybe you already have all this figured out though. Again, I could be way off on what you are looking for out of the project and this is just my thoughts from an outside perspective. I love your videos and watching you solve all of these problems! Keep on Keepn' on man!

Hi, first of all, very nice modeling with not only functionality in mind but also esthetics! As an idea to solve the deviating rotaions, Maybe you can decrease the amount of bounces by let them enter in an angle? This way you can also use longer bolts aswell.

[@cosmin6988]

I think some kind of an escapement mechanism that locks the column above, drops a screw and repeat would have worked, it would have minimized the fall distance and also seal the tube from leaking pressure into the screw tank. Great job indeed, also love the debate in the comments

[@LetsJeep]

In my experience with part feeders, never allow stubborn parts much free movement in air. Where that becomes an issue avoid bouncy hard surfaces and free space by controlling the part into the next transition or redirect. While mid-air assembly looks cool, it's impractical once the parts are no longer captured in path where timing and alignment are critical. Drop them out of the escapement or feed path when together. The best parts of your video's are the trial and error, cause and effect solutions letting it teach you how to rectify the issue.
