Automated tools reduce operator training requirements
Back To Why NPT
New Precision Technology is constantly researching new machine features to benefit our customers. Not only do we attempt to resolve existing production issues, we attempt to anticipate future issues and develop solutions that integrate seamlessly with minimal production impact. Fifth generation devices now cross-communicate, leveraging our production systems so that the whole is far greater than the sum of the parts.
Traditional dispensing tools are faced with process variations such as : temperature, part variation, fixture variation, and even operator variation (!) that require continual manual adjustments in pressure, speed, and even path location. These circumstances encourage the evolution of a unique plant position - knobologist. With our tools and processes, we eliminate the knobologist. The inclusion of these tools into a machine transforms a standard CNC platform into a stand-alone, high-precision, low-cycletime gasket applicator.

Automated vision system sensing
One tool used to reduce the impact of continual production variations is the automated vision system. Capable of finding the center of features within milliseconds, this tool provides rapid part alignments, compensating for both rotational and translational offsets. In the given example, the part is simply placed on a conveyor belt and the system can align the part automatically.

Laser Needle Tip Calibrator
This unit uses a retro-reflective laser and sophisticated software to determine the actual dispense tip location in XYZ space. Unlike many units, the software calculates the effect of any bend and interpolates the actual tip location. Because of this interpolation, which is done on both sides of any axis scan, this unit holds +/- 0.002" (+/-0.050mm) locational accuracy.
Additional features include the ability to scan taper-tipped nozzles, and a drop-through design that protects the optics from adhesives and other liquids.
