I have a spool of wire and i need to cut it into 5000 pieces of 10 cm lengths.
Is there a DIY way to automate this process

>> No.708529

>>708526
coil it around a 32mm tube, use a knife to cut the turns?

Ok you nerd, now you have to tell us what kind of amazing device you are building that needs 5000 interconnects..

>> No.708531

>>708530
Sorry to disappoint you, its not an amazing device.
At work we have these radiomodules inside a handheld device, these need antennas.
Cutting, stripping and presoldering them is a timeconsuming task, and i want to automate atleast on task of it.

>> No.708535

>>708531
Oh snap. That would suck total balls. This guy >>708529 is on it though, that's how I'd be cutting them out.

Meanwhile is this single core or multicore wire? If single core, instead of stripping each wire you may be able to get away with passing the tip through a flame, which should shrink the insulation back enough to expose the conductor. I have only ever been able to use this technique with single core, for some reason, multi has never played the game.

Good luck man.

This is a multicore 20 AWG wire

Why not just use

>>708548

But put a blade on the wheels so that it constantly spins and cuts the (20ga isnt that thick) wire as it spins though.

Use an arduino and a stepper motor and you're done.

>> No.708659

>>708629
your solution is not really useful if i want a different length in the future

>> No.708675

>>708526
Rough ideas follow.
Get a stepper motor. Determine runtime to achieve desired length. Keep wire taut whole time. Set up a guidehole or 2 after it and then a cutter. Run motor another cycle. Cut wire. Repeat.
Easiest way to strip solid wire in mass groups is to use a lighter , heat wire tips for a sec and then just pull off with fingertips. It'll usually slide right off and won't even be hot. If you're somehow using like THHN multiconducter, this won't work for shit.
Stranded should work the same but it just seems to be more problematic.

Challenges will depend on budget. I'm sure there is a prebuilt solution that is outrageously priced.
Easiest cutter I can think of would be a solenoid guillotine. Get a solenoid with enough force and attach a razor blade to it. Shouldn't take too much.

If you're going to be doing this often, buy a machine designed for the purpose, or buy pre-cut wire.

I'm guessing OP wants to incorporate the stripping so he doesn't have to use two machines and design a feed for already cut wires.

Maybe something pic related. Of course, more springs, motors and actuators, less weights and pulleys as well as 3d placement makes this much more "cleaner".

Where is the DIY in that?

>> No.708712

>>708529
This. Use a drill you have lying around to spin the roll quickly while having the origin spool set to spin freely. After it's tightly wound, just snip through it. Of course, the more layers you do at once the longer the wires become.

Sure it is, just have an adjustable armature that allows the installation of different size wheels for different lengths.

This is simple, cut it into 1m lengths, then tape them together, cut all at once. If whatever you're cutting with can't handle 50 wires at once, cut it into 2m lengths.

The time you'll take to make a device will be far more than just cutting it into little bits.

(me=not OP)
>>708708
stuff like this is easy to draw but takes a lot of time and money to build, even if you have access to machine tools.

also the weights controlling everything properly are ,,,,, optimistic.

you could CNC it but that would cost $200 for the electronics, plus you would need to know how to program enough to get it to work (that is not real hard, but still)

most realistic: wrap a loop of 20-30 turns in your hand about 10cm long and cut with wire cutters.

You might do well by wrapping it around a long piece of ply cut to the appropriate width, using a utility knife and a metal yardstick to cut it. You could round the edges of the ply with something so they don't kink the wire. You can even clamp the yardstick to prevent it from slipping.

>> No.709495

I would use a stepper motor as a spool feeder. similar to how welding spoolers feed wire as a certain rate.

then just have a guilotine cut everyso often and then the wire drops off into a pile

I keep imagining Chinese 3rd-graders having homework assignments like soldering ICs onto circuit boards and putting phone screens into cases

For an engineering class, which would explain posts like >>708709 and >>708973. Because unless the goal is the cutting process itself, insisting on doing it yourself instead of paying your supplier a bit extra for the service is both stupid and ineconomical. Unless the OP really is a Chinese 3rd-grader sweatshop worker.
