In-Line, Automated Dimensional Measurement Systems

Nikon Metrology has completed its series of NEXIV VMZ-S video measuring machines with the introduction of two larger models. Pictured is the largest capacity machine, the VMZ-S6555, with a 650 mm x 550 mm x 200 mm measuring volume.

Two new models have now been added to Nikon Metrology's latest NEXIV S-range of CNC video measuring systems, which are suitable for in-line, automated dimensional measurement tasks.

The NEXIV CNC video measurement system can automatically measure the dimensions of component features using Nikon's optical and image processing technology. "By analyzing the captured image of a component, detecting feature edges at high speed, both accurately and with repeatably, it is possible to quickly measure components with simple and complex features," said a company spokesperson.

The spokesperson continued, "With the growing demand for measuring smaller components with higher performance, and the huge increase in the number of electronic components installed in automobiles, there is a greater need for video measuring systems to measure more components at higher speeds in automated production lines. The NEXIV VMZ-S series has increased throughput by maintaining and enhancing the performance of the previous model, the NEXIV VMZ-R series. The new VMZ-S4540 and VMZ-S6555 now join and expand this line-up and are perfect solutions for medium and large components or for loading multiple components."

"The NEXIV systems obtain the highest level of measurement accuracy using an exceptional stage featuring high-precision linear encoders," continued the spokesperson. The NEXIV VMZ-S series is capable of capturing and processing images at higher speeds than its predecessor, the NEXIV VMZ-R series. This has made it possible to reduce the component measurement cycle times without compromise in accuracy or reproducibility."

Nikon has designed an optimized optical system to deliver high quality images and accurate measurement data from within the field of view. With a movable LED ring light and an eight-segment LED illumination, it is possible to resolve and capture the edges of complex shapes. In addition, a high-speed laser, scanning at 1,000 points/sec can acquire the cross-sectional profile across a surface and evaluate the relative heights. This meets the surface quality and feature measurement needs across a wide variety of samples.

The measurement software environment of AutoMeasure offers high accuracy and speed along with simple measurement functions. A large library of tools is available to use in a user-friendly GUI. For simple components, a support function will automate part of the measurement programming process.

The joystick unit used to move the stage and measurement head has also been redesigned for greater ease of use.

Up to 10 NEXIV systems can be controlled remotely by using Remote Control SDK (optional), enabling centralized management and distribution of measurement programs and results all from one place. By controlling NEXIV and measurement programs from a remote location away from the production line, such as a control room or office, manpower can be streamlined and productivity improved.

By combining the NEXIV VMZ-S series with in-house or third party automatic wafer loader systems, the process of loading wafers and feature measurement can be efficiently automated.
