Multifunctional Tabletop Robots

Positioning and mounting platforms for a variety of applications

Eight Different Series of Tabletop Robots

The TTA tabletop robots, the improved successor model to the successful TT series, are extremely flexible, precise and multifunctional positioning and assembly platforms.

In total, eight different TTA model series are available with working areas between 200 x 200 mm and 500 x 500 mm. With a stroke of up to 150 mm, the Z-axis can also accept camera systems for image processing whilst at the same time moving a total load of up to 6 kg. Furthermore, an optional rotary axis has also been integrated into the existing cartesian positioning system.

Gate or cantilever type

The gate type is suitable for applications in which high rigidity is required, while the cantilever type is frequently used where space is limited.

The gate type has a stationary Y-axis for the handling of load capacities with an uneven weight distribution. It is particularly suitable for applications in which the X-axis has to accept a heavy load, or whenever a large part of the load capacity extends beyond the slider.

The cantilever type enables greater free space, so it is ideal where load capacities with larger dimensions or with irregular shapes have to be transported under specified unchanging conditions.

Scope of performance

The scope of performance of the built-in controller has been significantly increased in the new TTA series. The memory capacity has now been extended to 255 programs, of which 16 can run simultaneously. In total it is possible to store 30,000 positions.

Additional optional I/O signals have been provided for the external communication, so that up to 48 I/Os are now freely available. The torsionally rigid base frame allows a repeatability of +/- 0.02 mm for the complete system.

Travel speeds

The maximum travel speeds of the individual axes are around 800 mm/s (for the X and Y axes), around 400 mm/s for the Z-axis and around 1,000 ⁰/s  for the rotary axis. The tabletop robots are also alternatively programmed using a PC or a teaching pendant.

Extensive range of applications

The tabletop robots are extremely flexible, precise and multifunctional positioning and assembly platforms. The range of applications in which they are used is accordingly extensive. These extend from micro-dosing in biotechnology and the population of printed circuit boards in the electronics industry to screwing and pressing in mechanical engineering.

However, they are also used in the overall quality assurance and in surface coating. Soldering, simple pick & place tasks or sorting applications are further fields of use of these systems.
