Sorry if this is in the wrong spot, but I'm fairly new to this. I'm trying to design a small tray that will be able to move vertically along a CD rack for a retrieval system. I'm probably going to be using an empty shell of a CD drive for in/out movement in grabbing the CD from the appropriate slot. If I have to I can make my own tray, that's not really an issue.
I've been thinking about the best way to accomplish the vertical movement and I don't know a lot about leadscrews, wormgears etc. I've been looking at a lot of stuff online (most of it patent junk) and while I have a general idea of how these things work I would like some clarification.
The device itself will not be heavy and the load (a CD) is not heavy either. Would a leadscrew setup and guide rails along the side be a good way to go about this? I like the wormgear idea as it would essentially lock the tray in position once it reaches its destination, at least from what I've read. The device will be powered by electric motors, perhaps a stepper motor. Am I on the right track?
Thanks for any input.
