It is a methodology used in Vision Guided Robotics (VGR) systems in which stacked pieces are selected and extracted in a container, using a vision system for location and a robotic system for the extraction and lately its relocation.
It is a Vision Guided Robotics (VGR) system that identifies an individual piece through a vision system, proceeding to a subsequent grip and positioning using a robotic system. The function of Bin Picking is to automate the task of removing the parts randomly arranged from a container.
This process has 4 stages:
A reliable, robust 3D object recognition system optically
collects and evaluates the data.
The specially developed software segments, identifies and selects information about items and constraints.
The intelligent gripper with additional axes enables collision-free removal of items from the shipping container.
The parts are precisely positioned on the processing device.
The InPicker software is based on a 3D image analysis system that can recognize and determine the position of stacked objects in a container. From the recognition and the selection of the best option, the system determines the position of the object in a three-dimension space, guiding the robot claw with the most precise orientation, to extract the selected object. In the movement process of the robotic arm, the system knows the exact position of the container and the stacked elements to avoid any possible collision.
The InPicker software is suitable for complex components, becoming one of the few worlwide Bin picking systems, processing irregular shapes and multiple frameworks.
Additionally, the Inpicker software has been design to identify and extract textured components like boxes or metallic and plastic pieces, to be unpalletized even they are ordered or disordered.
Likewise, the InPicker software detects grip and robot collision what is essential in Bin Picking applications.
The system is based in the identification of 3D images throgh different acquisition technics as passive stereo, active stereo or laser triangulation set, integrated by high definition cameras placed on the robot’s head, and through the capture of synchronized pictures, it is able to make a 3D map of the elements in the scene and select and extract the object that is considered the best candidate.
At the same time, it is capable to recognize through artificial vision the work scenario, which allows to guide the robot avoiding collisions with elements in the surroundings, the container of other pieces to extract.
Some drivers have been developed for different kind of robots that makes it easier to integrate for both engineering and OEM’s. The robot makers Universal Robots and ABB have already been used in the installations made, and are currently developing drivers for the most standard robot manufacturers on the market.
With an average cadence inferior to 8 seconds per piece, the InPicker is able to unload a container in a very short amount of time and without errors or interruptions. The possibility to use the system in a continued way, during the three daily work shifts, makes it a really interesting product for continuous production systems.
The acquisition of a Bin Picking robotic cell, with our technology, has a return on investment, in a short period of time, and also depending on the working environment. The possibility of working with collaborative robots also allows to reduce the costs related to the security of the system, and can reduce the fence costs of the installation, in case the whole work environment is really collaborative.
The Bin Picking system offered by Infaimon includes:
- InPicker software
- Stereo Machine Vision head, composed by 2 high definition cameras, with the right lens for every application.
- Illumination system
This Bin Picking system is oriented to systems integrators specialized in robotics, so that the decision of the other components: Robot, Claw and work environment depend on the application and the decision of the integrator itself.
