Tool Center Point Check and Determination of Robot Tools

VMT TOOLBox 3D

Tool Center Point Check and Determination of Robot Tools

Tool Center Point Check and Determination of Robot Tools To guarantee a constant high application quality in robotized production processes, a regular validation of the Tool Center Point‘s (TCP) are an essential function. Especially in high-precision application processes the accurate tool positioning is crucial. In addition to the basic TCP Check the VMT TOOLBox 3D provides the automatical TCP Correction as a supplementary feature. To do this in an reliable, precise and fast way VMT developed the VMT TOOLBox 3D.
 

TCP Check

To execute an regular TCP check the robot tool will be moved into a predefined position inside the VMT TOOLBox 3D. As soon as the position will be reached, the image aquisition starts.

  • The current TCP position will be compared with the nominal TCP position captured during the system setup (X, Y, Z)
  • In case of deviations above the individually adjustable tolerance limit the system generates corresponding message
     

TCP Correction

In addition to the TCP Check functionality the VMT TOOLBox 3D offers the option to execute an TCP correction.
 

  • The current TCP position will be compared with the nominal TCP position captured during the system setup (X, Y, Z)
  • The deviation to the baseline measurement will be transferred to the robot
  • The robot will adjust its TCP within the defined tolerance limits (X, Y, Z)
     

VMT TOOLBox 3D+

TCP Determination

In the version VMT TOOLBox 3D+ the fully automated Determination of the Tool Center Point is an further functionalty feature.

  • The robot moves in 8-12 predefined positions inside the VMT TOOLBox 3D+. In each position the defined tool features are in the visual range of the camera (e.g. the tool tip)
  • The image aquisition is executed in each robot position. Based on the image data and the positions of the robot flange the TCP (X, Y, Z, A, B, C) and VMT TOOLBox 3D+ position will be calculated (in robot coordinates).
     

Technical Parameters / Interfaces

  • Dimensions 273 x 273 x 110 mm (L x W x H)
  • Inspection bay 125 x 125 mm (L x W)
  • Inspection area entirely glazed
  • Inspection area downwards open to avoid contamination (dripping material etc.)
  • Power supply PoE or DC24V
  • Data transfer LAN
  • Digitale I/O‘s ( 2 x Input, 3 x Output)
     

System- and Installation Requirements

  • VMT IS Version 7.0.011 or higher
  • Communikation directly to the robot or via PLC SPS by ProfiNet, ProfiBus, InterBus, TCP/IP
  • DC 24 V or PoE
  • Robot ABB, KUKA KRC 2/4, VKRC 4, FANUC, DÜRR

As upgrade for existing installations, already consisting an VMT system

  • for robots without VMT BK-System to execute the TCP-Check
  • for robots without VMT BK-System to execute the TCP-Check and TCP-Correction (requires the Technology Package installation at the robot)
  • for robots with VMT BK-System to execute the TCP-Check and TCP-Correction
  • for robot with VMT BK-System to execute the TCP-Determination (Technology-Package Update necessary)

As upgrade for existing installations, without an VMT System*

  • for robots to execute the TCP-Check
  • for robots to execute the TCP-Check and TCP-Correction
  • for robots to execute the TCP-Determination (requires the Technology Package installation at the robot)


* Requires the upgrade of an additional PC incl. VMT IS
