Advanced Data Analysis for Resistance Weld Monitoring

Weld monitoring instrument supports process development, production monitoring, and data requirements for medical device development.Medical device manufacturers are experiencing an ever-increasing emphasis on process accountability. ADAM (Advanced Data Analysis Monitor) is a technology developed for resistance welding that gives manufacturers the information they need to support process development and production monitoring. It also supplies the data necessary to document quality requirements contained in ISO (International Organization for Standardization), good manufacturing practice (GMP), and total quality management (TQM) programs. The instrument monitors not only what happens after the trigger point of a typical weld monitor, but also before the trigger point, giving a 360-degree view of the process.

Embedded Vision System Increases Inspection Capabilities

Food manufacturers are held to strict agency regulations regarding product quality and consistency. Repeatable visual inspections are critical to ensure consumers receive a consistent and safe product. As regulations have increased, machine vision technology has become more intelligent to follow suit — a trend that some machine builders are using to their advantage.

Non-Contact 3D Digitizer

The Konica Minolta RANGE 7 non-contact 3D measurement camera from Konica Minolta Sensing Americas, Ramsey, NJ, has a scan range of 450-800 mm, an accuracy of ±40 μm, and a scanning input time of approximately 2 seconds per shot. The camera and its controller can be integrated into a single body weighing approximately 6.7 kg. In addition, the RANGE 7, which has a 1.31 megapixel CMOS sensor, features a 3D preview function and interchangeable TELE and WIDE lenses. A multi-focus mode also automatically shifts the focus position to provide three-dimensional measurement data, and an auto-focus function adjusts to a user’s specified points. User calibration can be performed with an optional, movable stand.

Thermal Imaging Processor

The combination of a ThermoViewTM Pi20 process imager and DataTemp® Pi (DTPi) software from Raytek®, Santa Cruz, CA, provides real-time viewing, archiving, and playback of both online and off-line thermal images. Featuring an IP54 rating, the fixed-mounted ThermoView Pi20 operates in two temperature ranges: -40 to 500 °C and 200 to 2000 °C. For each temperature range, two lens options are available: 21.7 × 16° or 30 × 22°. The ThermoView Pi20 provides networking over distances using a standard Ethernet interface, which transmits up to 30 frames per second. The DataTemp Pi software supports up to 16 Pi20 cameras simultaneously in a single software package, where each camera can have up to 192 process alarms to be assigned as relay outputs. The software interfaces to remote I/O modules and can be employed as triggering inputs, allowing for file saving.

3D Automated Metrology System

Olympus Integrated Technologies America, San Jose, CA, has released the Olympus IR 3D-IC Automated Metrology System, which provides IR microscopy and imaging technology to verify alignment of bonded wafers and through silicon vias (TSVs). The system observes and acquires images of alignment targets and vias by observing up to 1200 μm of bulk silicon to the patterned surfaces. Overlaid alignment marks are imaged and measured to verify bonding alignment accuracy.

Thermal Imaging Infrared Camera

The FLIR i5 and FLIR i7 thermal imagers from FLIR Systems, Portland, OR, produce infrared images with a 2.8" color display and 2% thermal accuracy. The FLIR i5, which has an 80 × 80 pixel resolution, provides a center-spot measurement mode. For extensive analysis of job sites, the FLIR i7, which has a RESNET-compliant, 120 × 120 pixel resolution, adds two measurement nodes: area (minimum/maximum) and isotherm (above/below). Both IR cameras capture temperature analysis/reporting in FLIR’s patented radiometric JPEG format.

Tracking/Tracing Trigger Device

The GigE Trigger Device from Baumer, Southington, CT, controls triggering, power, and image acquisition functions of GigE cameras. With eight inputs, the device integrates light barriers, encoders, sensors, and actuators, processing their signals internally and triggering cameras accordingly. The GigE Trigger evaluates input signals and provides real-time control of additional process steps. Images are transferred to a PC, and the resulting data is returned to the trigger device for follow-up action through the eight outputs that are available to control barriers or other export mechanisms, for example, or provide status messages. The device features industrial voltage level compatibility, simple DIN rail mounting, and a Baumer GAPI-SDK for system integration.

LCD Display Modules

Saelig, Pittsford, NY, has introduced the uLCD-32PT, a 65K thin film transistor liquid crystal display that has a 3.2", 240 × 320 pixel color panel with an integrated 4-wire resistive touchscreen. A 5-pin connection provides an interface to host devices and supports external SD/μSD memory cards for storing images, video clips, fonts, and data logs. Additionally, the module includes a dedicated PWM audio pin that works with FAT16 audio WAV files, an onboard audio amplifier and speaker, 2 × 30 pin headers for I/O expansion, 4.0V to 5.0V range operation, and support for available Windows characters. Two versions are available: one for standalone applications and another for serial-driven, microprocessor-based devices, allowing the display module to be used as a slave device where the external host sends screen-related functions using a serial protocol. The PICASO-GFX2 chip embedded in the uLCD-32PT (GFX) display allows users to write applications with 4DGL.

Four-Camera Vision System

The IMPACT® M-Series Embedded Vision System from PPT VISION, Bloomington MN, allows users to perform up to four inspections that can be initialized independently — at different times or simultaneously — using a single vision processor. Customers are able to program and operate the IMPACT software, which works with the Microsoft® Windows® XP operating system, and features a connection to a monitor or keyboard directly from its M40 processor. The processor uses the Windows XP operating system to transmit data and images, connecting directly to databases, SCADA systems, and other business system software.

GigE Line Scan Camera

Basler Vision Technologies, Barrington, NJ, has introduced new features to its Basler Runner GigE Line Scan Camera, adding Shading Correction, Multiplier, and Divider features. The Shading Correction option can be used to compensate for non-homogenous lighting conditions and more accurately detect defects. The Divider functionality reduces the frequency of an incoming trigger signal, while the Multiplier increases the trigger signal frequency. To create the correct line acquisition rate for the camera, the input/output features offer transformations for trigger and encoder signals from a conveyer belt. Both features can be implemented by determining the correct parameters, which can be adjusted within a wide range. In order to accommodate the required line trigger frequency over the broadest variety of applications, the options can be used simultaneously.
