Usage Methods
- Installation:
-
- Mount the camera using the integrated M4 threaded holes, ensuring alignment with the target surface and proper distance for the chosen lens (use lens calculators to determine working distance).
-
- Secure the lens to the C-mount, adjusting focus and aperture to optimize image sharpness and light intake.
-
- Position the camera such that the line of sight is perpendicular to the direction of object movement (for web inspection) to ensure uniform image sampling.
- Wiring and Connection:
-
- Connect the 12V DC power supply to the dedicated terminal, using a regulated power source to minimize noise.
-
- Connect the Camera Link cable to the frame grabber in the vision system, ensuring proper termination (follow Camera Link specifications for cable length).
-
- For external triggering, connect the trigger signal (TTL level) to the input terminal; for encoder synchronization, wire the encoder signal to the dedicated input.
- Configuration and Setup:
-
- Use Teledyne DALSA’s Sapera LT software to configure camera parameters, including line rate, exposure time, gain, and pixel format.
-
- Calibrate the camera for geometric distortion and lighting variations using a calibration target (e.g., checkerboard pattern) and software tools.
-
- Set up triggering parameters to synchronize image acquisition with object movement (e.g., using encoder input to adjust line rate based on web speed).
- Operation and Maintenance:
-
- Monitor image quality via the vision system software, adjusting lighting or camera settings if artifacts (e.g., noise, motion blur) appear.
-
- Inspect the lens periodically for dust or smudges; clean with a lens tissue and appropriate cleaning fluid if necessary.
-
- Check cable connections quarterly to ensure secure attachment, especially in high-vibration environments.
-
- Avoid exposing the camera to extreme temperatures or direct sunlight, which may degrade performance or damage components.
System Introduction
The DALSA CR-GEN0-M6400R3 operates as a core imaging component in industrial machine vision systems, integrating with three key layers:
- Imaging Layer: The linear CCD sensor captures light reflected from the target object, converting it into electrical signals proportional to light intensity. Each line of pixels corresponds to a cross-sectional “slice” of the moving object.
- Signal Processing Layer: The camera’s onboard electronics amplify and digitize the sensor signals, applying corrections for dark current and non-uniformity to produce high-quality digital images.
- Inspection Layer: The digitized image data is transmitted to a frame grabber or vision processor, which runs inspection algorithms to detect defects, measure dimensions, or verify patterns. Results trigger real-time actions (e.g., rejecting defective parts, adjusting production parameters).
In a paper web inspection system, the CR-GEN0-M6400R3 captures continuous line scans of the moving web at 65 kHz, generating high-resolution images. The vision system analyzes these images to identify defects such as tears, dirt, or thickness variations. If a defect is detected, the system sends a signal to a marking device or rejection mechanism, ensuring only quality products proceed downstream.
