Hello everyone.
I am going to purchase IRB 1200 5kg/900mm robot, here is one question I would like to ask before the purchase.
As you can see in the picture above, during my future application, I will have to put a 50N force along the way in red arrow, the force will be applied on my custom tool, and will have no offset to Axis-6.
I checked the IRB 1200 load diagram in this PDF file:
https://search.abb.com/library/Download.aspx?DocumentID=3HAC046982-001&LanguageCode=en&DocumentPartId=&Action=Launch
On page 25-30 I have checked both “load diagram” and “Maximum load and moment of inertia for axis 5”, but I can not find any information about the robot capacity to this kind of “sideway” force.
As I can imagine, the force will go against Axis-1 rotation, and maybe a little against Axis-4 rotation.
For the rest axis (2/3/5/6), I am not sure. The force is not against axis rotation, but I think there is a limit or range for these kind of force.
Does anyone know anything about this? I don’t want to damage the robot in the fure, if the force is too big for IRB 1200, I will have to consider purchasing a stronger robot arm.
Thank you very much!
