Kelvin Tool Changer was also at HI Tech & Industry Scandinavia 2019


At DanRobotics A/S the tool changer was demonstrated in action with a bin picker robot.

Components from sub-contractors are typically delivered disorganized in boxes. Picking up these items and feed them into robots in an assembly line is often the first big hurtle in automatizing a production.

With a 3D scanner this bin-picker can single out part in the box and pick them up with a robot arm.

Some parts are best suited to be picked with a suction cup, others with a gripper.
Here the Kelvin Tool Changer gives the bin-picker the ability to change between different tools.

This give a bin-picker unit the capacity to pick out a big variety of parts.

At HI Tech & Industry Scandinavia 2019, 4TECH Robotics also had some of its products on display at Danish Technological Institute

3D print

Most of the parts for the Kelvin Tool Changer is 3D printed by Danish Technological Institute and they had the tool changer on display together with a parallel gripper.

Our latest product, an adapter flange for robots, was also shown as an example of a product 3D printed in aluminum.

People, who visit Danish Technological Institute in Herning, had a chance to try a small 3D printed torque limiter. Many even got a torque limiter as a free sample.

This tool was actually designed by 4TECH as a tool for mounting the Kelvin Tool Changer.

If you were not one of the lucky to get a torque limiter in Herning you still have a chance to get your own torque limiter. Just by a Kelvin Tool Changer and you will find a torque limiter in the packet.


The robot as a module in the factory of the future:

Kick Off meeting at the RoboCluster project:
"Robotten som modul i fremtidens fabrik"



Bin Picking theme day at DanRobotics:

4TECH Robotics had the chance to demonstrate the Kelvin Tool Changer live at the Bin Picking theme day at DanRobotics

The tool changer was here installed on a robot from ABB

More info on the Bin Picking theme day

Kelvin Tool Changer is testing with a new bin-picker at DanRobotics A/S in Middelfart, Denmark


Four months at the assembly line:

Kelvin Tool Changer has now been used at the production for more than six months at SGM Light in Aarhus, Denmark

SGM use a UR5 robot for assembling front panels for their spotlights

The tool changer was first only intended for switching between dispensing glue and sealing, but now the robot also mount glass sheets in the frames


More info on the robot setup at SGM Light


Smart LAB:

A Kelvin Tool Changer is installed on an UR3e robot at Smart Production Lab, Aalborg University.
Smart LAB is the leading Danish research center on Industry 4.0

4TECH Robotics participates together with AAU Smart LAB and SDU in the RoboCluster project:
"Robotten som modul i fremtidens fabrik"

Spring 2019:

Ready for first test in production setup

January 2019 Kelvin Tool Changer will start the first test in a production setup.
The tool exchanger will be used to optimize dispensing different types of glue for parts in a serial production.
