A new high-speed, high-precision desktop robot offers an increased working area for applications such as screw-tightening, dispensing, soldering, and resistance and laser welding.

A new high-speed, high-precision desktop robot offers an increased working area for applications such as screw-tightening, dispensing, soldering, resistance and laser welding.

With an L-type body structure, and an aluminium-alloy, die cast single-structure base, the new product - manufactured by Janome - is extremely compact and robust.

Offering an x-y moving range (working area) of 500 x 500mm, the robot has high repeatability (+/-0.01mm), through the use of a very precise ballscrew, and is very powerful for its size, with a portable work weight up to 3.5kg for the z-axis and 7kg for the x- and y-axes.

With a data capacity of up to 6000 points, and 100 programs, the JR2500 also features a new, maintenance-free Flash memory card which needs no battery.

The product is supplied as standard with two serial (RS232) interfaces (one for the teaching pendant, the other for PC connection), and a third - for external I/O - is available as an option.

A simple sequencer is built into the robot, and operates independently.

No further hardware is necessary, because the I/O uses part of the robot's main external I/O port.

Exceptionally easy to use, the JR2500 features Janome's unique teaching and application software, supplied in memory card format.

This eliminates the need for a complex programming language, and enables novice users to familiarise themselves with the robot quickly and efficiently.

Another significant advantage of the new product results from its labyrinth structure, which prevents the ingress of dust, solvents and adhesives into the work tables or slide key.

With speeds up to 500mm/s (x-y), and 250mm/s (z), the JR2500 is driven by a five-phase stepping motor operating from a 90-132/180-250V AC supply, with a power consumption of 200W.
