Protected: VariCube R™

A STANDARD FLEXIBLE ASSEMBLY SOLUTION

RNA’s VariCube R™ presents a flexible assembly solution that utilises intelligent vibration platforms, coupled with industrial machine vision recognition and a 6-axis robot to feed and assemble component parts of various shapes and sizes.

Flexible Assembly Machine

Suitable for

Parts from 0.1mm to 150mm

The VariCube R™ offers flexibility, quick delivery time, reusability and speed. The VariCube R™ is best used in applications where conventional bulk feeding systems find limitations such as fragile or complex parts, multiple variants requiring fast changeover, and evolving component design. Guiding robot with machine vision provides high speed and high precision handling and assembly solutions.

VariCube R™ | RNA FLEXIBLE ASSEMBLY MACHINE

FLEXIBLE, RELIABLE AND STANDARD SOLUTION FOR THE AUTOMATED ASSEMLBY IN 6 STEPS


STEP 1: Various parts to be assembled are loaded in bulk into hoppers. Parts drop by vibration from hoppers onto FlexCube backlit vibratory platforms on demand.

STEP 2: The FlexCube complete pre-programmed vibratory cycles to orientate and separate component parts, presenting them to an integrated EYE+ vision system for robot pick.

STEP 3: The EYE+ vision system inspects the component parts on the FlexCube platforms and identifies which are laying in a position suitable for being picked. The coordinates are sent to the robot.

STEP 4: A 6-Axis Robot, with suitable end of arm tolling picks all identified component parts and places them in the proper orientation into the assembly nest.

STEP 5: The customisable nest is located by dowels for interchangeability and incorporate part present sensing. An overhead mounted vision system confirms positioning of the component parts before final assembly.

STEP 6: The robot unloads assembled component parts to a storage box via an unload chute.

FLEXCUBE™ | INTELLIGENT 3-AXIS VIBRATION SYSTEM

RNA FlexCube™ flexible vibration feeders offer high performance part feeding, pre-orientation and optimal surface distribution of bulk parts and components.

RNA’s FlexCube™ 3-axis vibration technology allows moving parts freely on a platform in different directions. Systematic part orientation can be achieved with intelligently structured platforms. Using RNA’s intuitive HMI interface, the platform vibration parameters can be tuned specifically for an optimal part distribution and fastest resulting cycle time. A functioning part feeding recipe is typically created in less than 5 minutes.

Compatible with all parts geometries: 99% of all parts can be separated by this feeding system, including parts featuring complex outer geometries, and highly fragile parts.

Minimum change-over times: easy exchange of part-specific vibratory plates provides for flexible and future-proof production systems.

Extremely gentle part handling with patented 3-axis vibratory system: Parts can be moved in all directions and flipping parameters can be stored for each specific part.

Free movement of parts in all directions thanks to the use of magnetic coil actuators, for optimal acquisition by camera system with the objective of presenting the parts in the shortest possible time.

No transmission of vibrations to the rest of the line thanks to decoupling of vibratory platform from the casing.

Systematic part orientation using intelligent vibration cycles.

Easy configuration with the feeding software.

HOPPER SYSTEMS

  • Compatibility: RNA BVL-P hopper systems have been developed to fit the various platform sizes and feeding tasks.
  • Plug and play: our hopper systems come factory-tuned and are easily integrated in the complete concept thanks to the enclosed control system. The discharge height is adapted for part transfer to the downstream FlexCube system.
  • Demand-based feeding: BVL-P hopper systems are designed for optimized part transfer rates to the sorting platform, which are key to achieving short sorting cycle times.
  • Enhanced autonomy: the filling volume is easily adaptable to your needs through the addition of static or upstream hopper units. And of course, communication between these hopper systems can be handled by RNA controllers.
