3D scanning station - camera triggering problem

Dear Users!

I have a very difficult question.

We have a project, where we would like to scan a workpiece with a 3D camera. For linear motion of the camera an ABB robot will be responsible.

The problem is the camera has to be triggered at every 0,1 mm on the linear path.

Unfortunately I did not find such an instruction in the RAPID manual, but I found in the Continuous Application Platform the CapEquiDist instruction, which has a function similar to that I need.

 

Do you have any information or solution how I could solve this problem?

 

Thank you for your answer.

    Hi,

     

    The answer would depend on how fast you are moving with the robot - if you are going too fast then triggering an output every 0.1 mm becomes very difficult.

    What spped are you using?

    Hi!

    The speed of the TCP have to be about 70 mm/s. So it should give 700 pulses in 1 second. I have looked after this, and it is not possible with the standard DIO of the robot.

    Fortunately, we chose another solution how to measure the part.
