Coherix Corporation: Precision 3D Machine Vision and Adaptive Process Control
Coherix Corporation is a rapidly growing technology company specializing in the development and manufacturing of advanced three-dimensional (3D) machine vision systems and proprietary software for adaptive process control in precision manufacturing. Headquartered in Ann Arbor, Michigan, USA, the company is a critical supplier to global industries, including automotive, electronics, aerospace, and general manufacturing, providing solutions to manage and control complex, high-speed production processes. Its core focus is on perfecting the automated dispensing of structural adhesives, sealants, and other critical materials, positioning the company as a key enabler of the "factory of the future" and Industry 4.0.
The primary objective of Coherix???s technology is to move manufacturers beyond simple inspection to real-time, autonomous process prevention and control, thereby eliminating defects, reducing material waste, shortening time to market, and ensuring 100% reliability. The company has achieved this through significant investment in the development of its pioneering 3D-enabled adaptive-process-control technology, which is capable of automatically adjusting the application of materials on fast-moving production lines to preemptively eliminate potential errors. Coherix currently serves a vast global customer base, including more than 50 carmakers and 75 Tier One auto suppliers, with thousands of its 3D laser-based inspection systems deployed worldwide. The company maintains a global footprint with operations in China, Germany, Singapore, Mexico, and Japan to support its international clientele.
Core Products and Technologies
The product portfolio of Coherix revolves around its core enabling technology, Coherix 3D???, which provides robots with depth perception and unmatched accuracy for complex robotic dispensing applications.
Coherix 3D Inline Inspection
This high-speed 3D imaging and processing platform utilizes multiple high-speed 3D laser sensors, typically four, to provide a 360-degree view of an adhesive or sealant bead. It is designed as a self-contained, around-the-nozzle solution that can be either robot-carried or pedestal-mounted. The system performs a robust inspection, measuring critical bead characteristics 400 times per second per sensor, which include:
Bead Height and Width
Continuity and Volume
Location relative to the part
This inspection is impervious to ambient lighting and part color changes, a key advantage of its laser-based design.
Coherix 3D Adaptive Process Control (APC)
This represents the company's most advanced solution, moving beyond simple measurement to active, closed-loop control. The APC system uses the constant stream of data from the 3D sensors and analyzes it with proprietary software to detect imperfections and immediately communicate with the dispensing robot and system to adjust on the fly. This real-time adaptation prevents errors and ensures consistent quality. Key software features that underpin the APC system include:
AutoRepair: Automatically detects and repairs dispensing imperfections like gaps, bubbles, or neck-downs in the adhesive or sealant without requiring human intervention.
LocationMaster: Locates the part in 3D space, compensating for misplacement or variation, and transmits precise offset information to the robot to dynamically modify the dispensing path.
Z-Tracking: Dynamically adapts to individual part variations and maintains an acceptable tip-to-part distance, thereby preventing nozzle crashes and scrapped parts.
RobotAssist: Helps programmers maintain the correct tool angle and nozzle distance relative to the part surface for optimum dispensing.
NozzleCheck: Monitors the dispensing nozzle to prevent material buildup that could compromise bead quality.
EyeSight Modular Software Platform
All of Coherix's 3D vision inspection systems operate on this proprietary software platform. Developed over many engineering years and field-tested in thousands of global installations, the modular architecture allows for the rapid development of customized applications and provides a stable core for data analysis, visualization, and process control.
