Small, autonomous robots
Tabletop robots are ideal for small batches with applications such as dispensing, assembly, cutting, soldering and quality inspection because of their versatility.
TTA tabletop robots are precise positioning and assembly platforms with working areas up to 500 x 500 mm and horizontal payloads up to 30 kg. The Z-axis can also accommodate camera systems for image processing with a stroke of up to 150 mm.
The maximum travel speeds of the individual axes are 800 mm/s for the X and Y axes, 400 mm/s for the Z axis and 1,000 ⁰/s for the rotary axis.
Tabletop robots from IAI are also frequently used in the laboratory as self-sufficient production islands.
Possible applications
- Soldering and pressing
- Pick & Place tasks
- Sorting applications
- Microdosing
- Screwing
- Printed circuit board assembly
- Surface coating
- Quality assurance
The gate type is suitable for applications in which high rigidity is required. The cantilever type is frequently used where space is limited.
The gantry type has a fixed Y-axis for handling payloads with uneven weight distribution. It is particularly suitable for applications where the X-axis has to carry a heavy load or where a large part of the load capacity extends beyond the slider.
The cantilever type allows a higher flexibility when, for example, payloads with larger dimensions or irregular shapes need to be handled.
With the TTA table robots, up to 255 programmes can be stored, 16 of which can run simultaneously. Up to 30,000 positions can be defined and up to 9999 programme steps are possible.
The autonomous table robots can be programmed directly on the unit without a PLC or with a "teaching pendant".
This manual effort is not necessary, however, because programme creation works conveniently via a PC with the SEL programme generator. Either DXF data can be read in or the travel path can be drawn with the PC mouse. The programme is then generated automatically.
Up to 48 I/Os are available for external communication.
The following field networks are supported: CC-Link, DeviceNet, PROFIBUS-DP, EtherNet/IP and EtherCAT.
All TTA tabletop robots are equipped with a high-resolution battery-free absolute encoder as standard.
The advantages of these encoders lie in the shortened downtimes, because no reference point has to be approached during commissioning after an emergency shutdown or faulty operation.
In addition, there is also no need for maintenance and replacement of the back-up battery, which is used for position storage.
