Automated QC allows unattended operation

Back To Software | Why NPT

Automated quality control is realized quite effectively through our direct machine control model.  This enables us to further close the process control loop between sensing and dispensing, allowing the robot to compensate in real-time for process variations.  Trainable sensor models can perform signature analysis and allow precision sensors to deal with production variations and still prevent false negatives so that the positives are only those parts with valid problems.

This concept addresses something that is an issue with common, off the shelf (COTS) SCARA or 6DOF robots: dealing with process variability.  Without the automation having the capability to adjust automatically to variations in parts, materials, and environment, you need to either accept looser tolerances or greater reject counts.  With adaptable automation, there is now a governing automated ombudsman that can fix some of these issues, resulting in higher yields.

3D Planar Correction

3D Planar Correction

    New Precision Technology announces true 3D planar correction! With the measurement of three points on a part, the CP System software can re-orient a part path for best-fit, further decreasing potential reject rates. Capable of being used with either tactile or laser based measurement systems, this easily incorporated feature brings added value to a system essential for quality gasket dispensing.

Automated profile analysis

Automated profile analysis

    This software allows the automated analysis of profile scans. It collects data from a laser system traveling through a region of interest, applies mathematical algorithms to extract features of interest, and reports not only the traditional pass/fail, but also how close we are to pass/fail. This enables our control software to modify machine parameters in response, which allows for the constant improvement of the process in response to environmental and rheological changes.

Automated vision system sensing

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.
