electronic camming & high-speed robotics with RSM Technology®

What is SYMPHONI™

SYMPHONI builds on the best proven assembly technologies – robotics, cam-driven synchronous machines, and power-and-free asynchronous systems – and cleverly combines them for unparalleled performance.

By removing unnecessary motion, Overall Equipment Effectiveness (OEE) is increased because the camming is digital, as opposed to mechanical. This is how the core efficiency methodology is integrated into
the e-Cam and SYMPHONI as a whole.

Efficiency is at the Core of SYMPHONI

The Electronic Cam 

The e-Cam is a digital camming system that represents a significant innovation in the field of camming technology. As an ‘electronic camming’ system, it stands out as the next generation of traditional mechanical cams.

  • Flexibility Adapts to different phases of the production process.
  • Efficiency Maximizes productivity by switching to high speeds during non-critical processes.
  • Precision Ensures sensitive operations are handled with care, maintaining high-quality standards.

THE Versatile SYMPHONI RSM ROBOT ARM

The e-Cam’s variable machine rate provides significant operational flexibility. This feature enables SYMPHONI to operate at different speeds depending on the requirements of the task at hand.

Precision and Performance

When focusing on crucial processes that require careful handling of parts, the e-Cam offers both precision and peak performance. This ensures that sensitive operations are executed with the highest level of accuracy.

High-Speed Operation in Non-Value-Added Processes

The e-Cam’s variable machine rate provides significant operational flexibility. This feature enables SYMPHONI to operate at different speeds depending on the requirements of the task at hand.

The e-Cam’s digital camming system revolutionizes traditional camming by providing a versatile, efficient, and precise solution for modern manufacturing needs.

The SYMPHONI Robot

Versatile Delta Robot

The workhorse of SYMPHONI technology is its RSM Arm. With precise multi-axis motions and robust construction, the SYMPHONI robot perfectly blends speed and power. Moving in the x and z planes at high speeds, it executes operations with startling efficiency.

Advanced Handling Capabilities

When equipped with servo-driven end effectors, the SYMPHONI RSM Arm offers advanced handling capabilities:

  • Picks up randomly oriented parts
  • Rotates parts to precise radial positions with friction-free contact
  • Optional tilt axis for inverting parts or carrying out assembly tasks at selectable angles

Strength

Unlike general use ‘spider’ robots, the RSM Arm can handle high forces. Its arms have been optimized through finite element analysis for minimum mass and maximum strength. This optimization provides:

  • Nimbleness to stroke at high rates
  • Power for heavy-duty operations

User-Friendly Operation

Best of all, the RSM Arm is easy to use. Its motions are configured with selectable profiles that are pre-programmed for common assembly tasks, making it user-friendly and efficient for various applications.

Standard, Pre-Engineered Design

Up to two RSM Arms can be pre-packaged in a module. Motion control is local, managed by the module’s embedded control hardware and SYMPHONI software.

The Pick-and-Place Station

Most assembly systems feature pick-and-place stations in which components received from external feed systems are placed onto a pallet and/or assembled to another component.


The SYMPHONI RSM Arm carries out pick-and-place operations with unmatched speed and efficiency.

Coordinated Movements

The SSYMPHONI RSM Arm coordinates its movements with the numerically controlled movements of other components, including:

  • SuperTrak CONVEYANCE™ pallet
  • RSM Technology® Disc

Configurable

End-of-Arm Tooling

SYMPHONI’ ‘s patent RSM Arms are configured by equipping them with a standard end-of-arm ‘deck’ and part-specific touch tooling, as shown in the image below.

There are numerous decks to choose from, depending on whether:

  • additional axes of motion are needed for orientation or inversion whether the operation is to be carried out 1-up, 2-up, or 4-up; and
  • on the type of grippers required. 

Pre-Programmed Motion Profiles

Although the RSM Arms can be programmed to execute a vast array of customized movements, it can also be quickly configured to follow commonly used motion profiles.

These standard movements are selectable from a library, making programming simple and fast. Specific pick-and-place points can then be dialed in within defined limits in 0.01 mm increments.

I-Profile

Any combination of pressing, orientation, screwing, and assembly.

J-Profile

Pick-and-place vertically.
Disengage part horizontally.

L-Profile

Pick horizontally.
Place vertically.

U-Profile

Pick vertically.
Place vertically

W-Profile

Pick and stop at mid-position to inspect or reject. Unload at second position.

Z-Profile

Pick horizontally.
Place vertically. Disengage part horizontally.

Powerful Performance

The e-Cam is a digital camming system that represents a significant innovation in the field of camming technology. As an ‘electronic camming’ system, it stands out as the next generation of traditional mechanical cams.

Key Features

  • Cycle Speed Up to 200 strokes per minute.
  • Configuration Options Can be configured for 1-up, 2-up, or 4-up operation, allowing flexibility in throughput.
  • High Throughput In ultra-high-output applications, multiple robots can work in parallel to achieve production rates exceeding 1000 parts per minute.

Operation Process

  • Radial Orientation Incoming parts are radially oriented and captured in an RSM Technology® Disc.
  • Vision Inspection A vision camera detects the orientation of each part.
  • Part Handling The robot picks parts from the Disc. During movement to the SuperTrak CONVEYANCE™ pallet, the robot rotates each part to the correct radial position.

Enhanced Inspection

  • Additional Vision Camera An optional second vision camera can be added to inspect parts while they are in the RSM Technology® Disc.
  • Faulty Part Rejection Parts with defects (e.g., short shots, excessive flash) are identified. Defective parts are rejected into a local reject bin, preventing them from entering the main machine.

Benefits

  • Efficiency High-speed operation and multi-robot parallel work capability significantly increase production rates.
  • Quality Control Advanced vision inspection ensures only quality parts proceed through the production process, reducing waste and maintaining product standards.

SYMPHONI is cam-based, with each movement in the system geared, just like traditional line shaft systems; however, SYMPHONI’s cams are electronic (e-Cam) and thus digitally configurable. This means adjustments in e-Cam profiles can be made at any time – through the HMI.
