Description
Industrial Bin Picking for Machine Tending Applications. Focused on solving unstructured picking and accurate placement of work-in-progress metal and plastic parts.
Look for processing applications include drilling, tapping, polishing, grinding, deburring, test and inspection stations, milling, welding and CNC machining.
Single part type in a bin only. Avoid assembly operations where multiple parts need to be picked in one station. Target applications where the goal is continuous operation and where customers expect to refill/replace bins before being completely empty.
Cycle Time:
Our average bin picking cycle time will be 10-25 secs depending on part, so look for machine/process cycle times in the 10-90 second range.
Target Part Types:
Tubes and Cups – preferably less than 6” but up to 10” can work
Volumetric or multi- sided – look at how these parts generally lie in the bin – the commonly presented sides must by pickable with a single end-effector type. Generally smaller than 2 fists in size (~6” x 6” x 6”). Larger parts possible but may require integration to refill/replace bin frequently.
Flat – thicker than 2mm for Medium sensor, thicker than 5mm for Large sensor. Must be pickable on both sides, ideally there is a part feature that identifies top from bottom.
Other Part Considerations:
Generally, part sizes should be between 1” and 10”
Avoid: cable assemblies, floppy parts, glass, screws, flexible O-rings
Non-symmetrical parts must be distinguishable by their unique geometry or features on each side. Note: distinguishable features must be large enough to be picked up by the sensor; generally >1cm and not regularly obscured by adjacent parts in the bin.
Target Bin Size ranges: (W L D)
Medium sensor : Bin size up to: 630 x 490 x 450 mm (25 x 19 x 18 inches) (2 x 1.6 x 1.5 feet)
Large sensor : Bin size up to: 1100 x 970 x 850 mm (43 x 38 x 33 inches) (3.6 x 3.25 x 2.75 feet)
Placement accuracy : +/-3 to +/-8mm direct from bin to target
If part or placement target has self-aligning features (such as cylinders) this leads to higher accuracy
Utilizing self-aligning regrip fixture moves accuracy to UR repeatability
End effectors: Suction, magnetic or internal grippers
