BGA Inspection with EyeScan AT 3D from EVT

BGA Inspection with EyeScan AT 3D from EVTThe EyeScan AT 3D sensor – together with EyeVision image processing software can inspect the correct position of pins and check for the quality and position of balls on a Ball-Grid-Array. The connectors of BGAs can be inspected with the 3D sensor for various characteristics up to an accuracy of a micrometer (µm).

Thanks to the Scheimpflug-projection, the laser line stays focused and distortion-free. Even in a high-speed application, the captured images have a high resolution, and no lens distortion correction is needed. Every single bump of the BGA is inspected for its size and shape up to a µm-accuracy.

The EyeScan AT utilizes precision laser line measurement (or laser triangulation). The camera views a laser line, which is projected onto the component (in this case: the BGA) and calculates the height information from the laser line profile.

Utilizing a precision blue laser and on board FPGA the EyeScan AT 3D is capable of over 20,000 profiles per second with very high resolution to capture even the finest details. Additionally, the High Dynamic Range algorithm with threefold exposure allows inspection of bright and dark objects in the same scan without loss of speed.

3D image information is processed by the powerful EyeVision software which is programmed though an intuitive drag and drop interface.

EyeScan AT 3D with Blue Laser Line

EyeVision software by EVT now also supports a 3D laser triangulation sensor with blue laser. The new EyeScan AT 3D scanner is especially suitable for scanning metal or metallic surfaces.

AT3D blue BrainLight ringToday’s noncontact 3D scanners include one of two laser types: blue laser or red laser. Most 3D scanners, including EyeScan 3D scanners from EVT, user red laser technology. The new EyeScan AT 3D Blue, however, utilizes optically superior blue laser technology.

The blue-violet Laser has some clear advantages which provide better scan results. Because it has a shorter wavelength than a red laser, a blue laser delivers improved scanning results with higher resolution and up to a 50-percent reduction in data noise. The shorter wavelength creates a smaller laser speckle pattern, generating a sharper depth image. The blue laser is more effective when scanning metal, because a blue laser is narrower and finer than a red laser line.
Thanks to 20,000 profiles per second and the new blue laser, even complex component parts and surfaces can be captured with high accuracy. The extremely fast scans are possible due to the short exposure time and the preprocessing of data with a FPGA inside the scanner. The high dynamic range algorithm with triple exposure makes it possible for dark and bright objects to be inspected in one scan, without a decrease in speed.

EyeVision for Inspection of Laser Markings on Medical Products

Schere_mit_DMCMedical products undergo a number of quality and safety inspections and have explicit markings and identification. EyeVision image processing software is often used to inspect markings on medical products. A camera inspection system consisting of an EyeCheck smart camera, which includes EyeVision software, can be integrated permanently into the laser marker head, ensuring an accompanying image capture for verification and validation of the quality.

EyeVision software can read markings such as:

  •  alphanumeric characters such as serial numbers, date specification, etc.
  •  complex codes such as bar codes, 1D and 2D Data Matrix Codes (DMC)
  • company and brand logos

EyeVision software inspects the markings, ensuring consistent quality. Also, the contents of the codes can be inspected. The software includes commands for code reading as well as pattern matching, position, and measurement technology. This is especially important as the code is used for the product identification, traceability, product safety and quality.

The EyeCheck smart cameras are available in various variations and can be equipped according the production process and production line, with diverse sensors and lenses. All EyeCheck smart cameras have one thing in common: the EyeVision software. The software can be mastered in no time at all without special programming skills. Due to the drag-and-drop function and the self-explanatory graphical user interface, inspection programs can be created easily for reading complex codes and characters.

DMC and QR Code Reading with EyeSens Vision Sensors

EyeSens-KopieThe EyeSens DMC Code Reader from EVT is a compact vision sensor with integrated lens and illumination. There are three different resolutions: 736 x 480, 1024 x 768 and 1280 x 1024 pixels. The EyeSens has a 1/3“ CMOS sensor and interfaces with Ethernet, RS232 and RS422. The lens can be in 6, 12 or 25 mm.

The EyeSens DMC can also be equipped with the QR-code reader command. The codes are evaluated by EyeVision image processing software. The drag-and-drop programming does not require programming skills and the code reader command is easy to adjust in the graphical user interface. The user can also design their own interface, using the process mode.


EyeCheck Smart Camera – the Eye for the Robot

Throughout the world robots are used for applications such as packaging, soldering, adhesive bonding, coating, etc. The robots are usually equipped with smart cameras, such as the EyeCheck 1000 series from EVT. Due to the recent advances in image processing, application areas have increased.

Roboter_mit_EyeCheckEyeCheck Smart camera series from EVT offers a combination of a camera and Eye Vision evaluation and processing software. The camera housing contains the lens (the user can chose between 6 mm, 12 mm and 25 mm lenses) and the illumination (available in different colors). The EyeCheck 1000 is available in various resolutions, from 782 x 485 pixel up to 1280 x 1024 pixel, and contains the full command set of EyeVision software.

The EyeCheck systems can be used for robot positioning and object detection, custom-made solutions for position correction, and can be mounted onto articulated robots. The moving or stationary objects are illuminated with the camera-based LEDs. Thanks to the robust evaluation algorithms, EyeVision software delivers reliable results even in difficult environments.

EyeVision software also has commands for code reading, color and surface inspection as well as commands for measuring objects. The system is configured and controlled by the user via the graphical user interface. The drag-and-drop programming allows an easy adjustment to different objects. EyeVision software can be connected to an external computer or the control system of a plant via Ethernet or PROFINET. Applications such as position control can be used in combination with inspection, measurement and identification tasks.

EyeVision 3 with New PlugIn System

PlugIn_puzzle-KopieThe EyeVision 3 machine vision software is more flexible than ever. With the new plugin concept, third party software such as Halcon, Open CV or the Euresys library can be integrated into the EyeVision software library.

Using the new SDK for plugin development, it is easy to integrate evaluation routines into EyeVision. EyeVision supports x86 Windows, Linux, as well as ARM based Linux systems.

With the GUI designer and only a few mouse clicks, the user can open their own routines or the library routines of a third party maker without special programming skills.

Also the standard communication components allows easy integration into SCADA and PLC systems. This means, for example, that the OPC standard can use EyeVision software as an OPC server. With that the accumulated data (measurement data, position, etc.) can be sent to a client.

Additionally, the new Webshop from EVT makes it possible to offer plugins directly to other EyeVision software users.

New EyeSens ZQ Vision Sensor with powerful ZYNQ hardware

New EyeSens ZQ Vision Sensor With Powerful ZYNQ hardwareThe EyeSens ZQ vision sensors from EVT are much smaller than the standard EyeSens sensor. Despite the miniature design, they are powerful, due to the ZYNQ processor with dual Core ARM, and can solve image processing tasks faster than common vision sensors. Because of its small size, light weight and integrated lighting, the EyeSens ZQ is well suited for locations such as a robot arm.
Suitable applications are:

  • Code reading (DMC, QR, Barcode)
  • OCR/ OCV
  • Color Inspection
  • Measurement Technology
  • Pattern Matching / Contour Matching for Robot Vision
  • Counting Objects

The EyeSens ZQ is available with EyeSens software as well as the complete EyeVision software platform. Additionally, the camera features the option of an integrated FPGA, which is important for the fast preprocessing of image information.
The creation of an inspection program is also very easy with the drag-and-drop graphical user interface; there are no programming skills needed.
