Gantry Robots and Component Picking

Carefully. How about in a pyramid fashion if room allows. I guess it would matter how large the items are. This would tend to be the most stable. Just like in the grocery store for display. Just don't try to take the ones from the bottom first.

Hi Smith,

Use a vision system on the gantry, and locate a unique pattern on your part. If there is no uniqueness about the part create a paint dot or similar in one of the previous operations, then use it to locate. You could use a servo / encoder for the rotation.

Is "round" as in sphere, cylinder, or disk?

Your question is not complete with detailed information. Please give information about the item to be lifted etc.

You really need to supply more specific information but I once spent a large chunk of time designing and machining acrylic plastic component nests that were mounted on vibrator tables.

The idea was to randomly dump the components from bins onto the nest, then "shake" the nest and components until they fell into carefully designed recesses in the nests. Then the nests were moved (by robot) to an assembly line with pick and place robots (2 and 3 axis) to assemble sub-assemblies and the final product.

Pre-orienting components using this method saved a lot of time and money in high-speed, high-volume assembly without the complexity and cost of programming >3 axis robots.
