Vision Guided Robots
The rich and powerful visual guidance instills new intelligence into modern robots. Robotic systems can not only identify and track a wide variety of parts within their visual field, but also successfully grasp them and complete most material-handling tasks. Our expertise spreads across all major vision technologies, such as those developed by Cognex, SICK, Fanuc and ABB.
With ongoing advancements in vision guidance technology the wide array of items that Bastian can help you handle with robots increases daily.
How Vision Guided Robots Work
A conveyor carries parts into a robotic pick and place cell. A vision camera mounted above the conveyor continuously takes snap shots of the parts to identify which can be picked by the robot(s) the easiest. An encoder can be used to track the conveyor position and tell the robot, with pin point accuracy, where to pick parts. Once picked by the robot parts can be processed or placed accurately on a target or in a position. Using vision guidance some robots can approach up to 200 pick and place operations per minute.
Vision Guided Robots Configurations
Vision can be used to guide robots in small single piece applications as well as large bags or cartons picked off pallets. Vision can also be used for automated bin picking.
Vision Guided Robots Benefits
- Automates processes dealing with various products at various locations
- Eliminates fixtures and therefore reduces cost
- Increases reliability and efficiency through vision application
- Greatly expands the flexibility of robotic systems
Vision Guided Robots Applications
- Depalletizing – robot visually identifies individual products on a pallet and picks them off
- Assembly – precisely locates different components and assembles them into one work piece
- Inspection and quality control – vision monitors moving products on a conveyor and notifies robot to reject if a defective product is found
- Automatic sortation – Robot picks products apart into separate spaces based on visual features such as shape, dimension, and color
- Random bin-picking – large number of parts arrive randomly piled within a crate without separation; The robot visually locates each individual part and picks it out for sortation
- Mixed-load palletizing – when incoming products have different sizes, the robot visually determines their dimensions and intelligently stacks the products on the same pallet
Vision Guided Robots Specifications
- Throughput varies greatly but can reach up to 200 products per minute
- Vision can identify nearly all products of consistent shape and matte surfaces
- Precision can reach up to .03cm in error before tool compensation and nearly 0cm after tool compensation
- Vision sensor and its accessories can be robot-mounted or stand-alone
- Robotic system interfaces with PC or PLC
