Collaborative Robot for Arc Welding

Collaborative robots with low trajectory accuracy may cause welding defects as shown in the figure on the right.

Daihen, who knows everything about welding, has developed a new control technology to improve the trajectory accuracy of linear and circular interpolation, which affects welding quality, and installed it in collaborative robots.

Achieves high-quality welding with stable trajectory accuracy equivalent to that of industrial robots.

 

By adopting the same controller as an industrial robot, a wide variety of peripheral devices and functions can be used.Various welding methods such as CO2/ MAG welding, ultra-low spatter welding, and TIG welding can be selected to suit the site, and a full range of welding functions can be used, so they are applied to all welding sites.

 

The cooperating robot can work in the same space as a person without installing a safety fence.※1
Therefore, it is no longer necessary to secure a large space for introduction like conventional industrial robots.
※1 If a safety fence is not installed, a risk assessment by the customer is required.
FD-VC4 complies with ISO 10218-1 safety standard for industrial robots.
In addition, the Robot Controller conforms to the international standard "ISO 13849-1PLd(Cat.3" and safety certification by a third-party certification body has acquired.

 

The cooperative robot is equipped with a safety function that automatically stops when a force exceeding a preset contact detection level is detected.
In addition, it has an arm shape that prevents pinching of hands and fingers, and a design that eliminates corners, thereby alleviating impact during contact.

 

Easy-to-install, mobile, and easy-to-move collaborative robots can be easily relocated to suit customer conditions, such as changes in production volume or labor shortages.
Automation in large structures, such as shipbuilding, is also possible, and will be used in a variety of welding sites.
