VMT SpinTop

Available now: Next Generation - VMT SpinTop G2

In recent years, the VMT SpinTop 3D has established itself as a pioneering inspection system for adhesive bead control. In addition to the specially designed sensor with a dual laser triangulation head that rotates around the application nozzle, the complete solution for monitoring bead-like material applications also includes an extensive software package.

Faster, more precise, more efficient – that’s the modern adhesive bead inspection with the new generation. VMT SpinTop G2, presented in a modern black design, has been available since March 1, 2024, replacing its predecessor, the SpinTop 3D.

The "Next Generation", the SpinTop G2, sets new standards and impresses with improved performance. The optimal utilization of laser technology combined with robust evaluation algorithms reliably ensures the quality control of the adhesive bead. Particularly impressive are the new vision modules of the sensor, which provide triple the sampling rate at more than double the resolution, enabling more precise and detailed data acquisition.

With the SpinTop G2 transitioning to Class 2 visible lasers, the sensor has a wider spectrum to work with while still providing excellent stability in varying lighting conditions and dark surfaces. The sensor uses a combination of red and blue lasers to allow simultaneous acquisition at high frame rates. This results in new application possibilities and an overall optimized detection process.

The mechanical and electrical connections are identical to the current sensor, enabling easy retrofitting or upgrading in existing systems.

Key Features

The sensor head, which moves independently of the glue nozzle, allows the entire adhesive bead process to be measured. The transmission path for energy and data between the fixed and the rotating part of the sensor head is designed to be entirely non-contact and maintenance-free in order to reduce wear and tear to a minimum.

Measurement distances can be selected on a flexible basis, and cumbersome parameterization and calibration procedures are not required. All measurement results can be documented specifically for each vehicle, and can be visualized on the VMT user interface in a clear and self-explanatory manner.

Direct and earliest possible detection of errors during the glue application process
No reworking costs due to incorrect glue application in subsequent work steps
Comprehensive checks make it possible to cut down on possible previous glue overdoses
Cycle time savings through inline measurements directly during the glue application
Simple retrofitting of existing systems; existing system processes remain the same
Optimum positioning of measurement technology, since the VMT SpinTop G2 is mounted „around“ the glue nozzle
Minimum interference contours due to compact design
Customer specific detailed logging - each individual result can be displayed
Only turn-on and turn-off signals (triggers) must be added to existing robot programs

Features

Full three-dimensional check of adhesive bead (width, height, continuity, geometry)
Inline detection parallel to adhesive bead application
Resistant to color and contrast changes, different surfaces and reflections
Independent of the glue color - can be changed without new sensor parameterization
Flexible measurement distances can be set for the respective glue nozzle lengths
Two measurement units for optimum capture of 3D geometry
Free segmentation of test parameters and tolerances
Freely programmable and robot-independent rotation of sensor unit
Separate rotation axis for direct inline measurements
Non-contact, maintenance-free energy and data transmission
Technology package for communication with robot

VMT SpinTop G2 - robot-guided or permanently mounted

The VMT SpinTop G2 is mounted directly on the glue gun. The unit can then be guided along the work piece by a robot or it can be used as a stationary version. In the second example, the robot moves the work piece underneath the glue unit. The freely programmable rotation of the sensor unit means that the measurement range can always actively follow the application path.

Installation on the robot wrist joint is risk-free due to non-contact data and energy transmission. Broken cables or wear and tear of friction rings can be excluded. The VMT technology package installed in the robot guarantees the exact tracking of the adhesive beads.

Exact path check of the glue beads is also possible with a VMT SpinTop G2 that is installed on an existing application unit thanks to the online connection to the robot. The rotation is controlled directly by the VMT system. This does away with the separate set-up of a measuring run.
