Rotary Bond Tools — perfect for high speed assembly

 

Automated assembly is the future trend for mass production of miniature systems and hybrid micro systems. Manual assembly is generally too cost intensive (up to 80 % of manufacturing cost) or inadequate to achieve process stability.

 

Precision assembly requires automation

The challenge in automating micro assembly is the production equipment for handling the miniaturised components. The assembly process typically requires movements with multiple degrees of freedom, for which differing drive technology components, such as motors, gears, spindles, etc. are used.

 

The work area defines the size

The outer dimensions of these actuator components may not be greater than the necessary work area and the components to be handled as otherwise even the outer dimensions of the machines and robots would extend beyond the available work area.

 

Deploy the micro gears from Micromotion

To open up new, innovative application fields, Micromotion GmbH has developed a new generation of highly-precise, zero backlash micro gears: the Micro Harmonic Drive. This unique micro gear is the heart of a new series of miniaturised rotary bond tools that we have developed for use in machines that perform high-speed assembly.

 

The challenge lies in the mass

The desire for shorter and shorter cycle times has led manufacturers of high-speed assembly automation equipment to new challenges. Higher speeds and greater acceleration rates can lead to thermal instability and cause a loss of assembly accuracy and process stability.

 

The solution has many advantages

The designers of such machines must reduce the mass being moved — micro technology can help. The new Rotary Bond Tool from Micromotion GmbH is not only smaller and lighter, but also offers greater accuracy than conventional solutions. The small dimensions also mean that multiple bond tools can be arranged next to one another to gain a significant increase in productivity.

 

Interesting variants of the Rotary Bond Tool

At the heart of every Rotary Bond Tool is a Micro Harmonic Drive Gearbox built to customer specifications. The gearbox is driven by a motor. The high degree of integration reduces design and assembly overheads. Various options, including integrated optical detection, are readily available.
