Weld Inspection and Measurement / Tool Wear Measurement Applications

Software and Systems for Weld Inspection and Measurement

VisionGauge software assures accuracte weld measurements with our specialized measurement tools.

Welding is a fabrication process used across many manufacturing industries to fuse materials. Some industries have rigid requirements and standards for a part to pass inspection following a welding process. VisionGauge® software includes native inspection tools specific to weld measurement that will make the quality control and inspection of welding a much easier process.

VisionGauge®‘s weld inspection and measurement tool can be used to carry out the following measurements:

  • Generic welds (i.e. Leg, Throat and Root measurements)
  • Concave isosceles 45 welds
  • Convex toe – toe welds

VisionGauge's measurement tools can facilitate weld inspection and measurement.

As is the case with all of VisionGauge®‘s measurement tools, weld measurements can be saved to disk, sent directly to another application, included in a report, etc. VisionGauge® is also able to compute measurement statistics and create clear and effective graphs and reports with relevant weld measurement data. You can also annotate your images with text and objects to show exactly what measurements were taken.

With every license of VisionGauge® our image processing and analysis tools are available to automatically process the image before carrying out the weld inspection. This can dramatically increase the quality of your results.

In a specialized example of our software being used, VisionGauge® OnLine is being used for in-process automatic measurements of bellows as they are being LASER welded. VisionGauge® OnLine measures the position of the seams as the bellows rotate and transmits these measurements to the bellows welding machine via a standard RS-232 COM port. This way, the welding head on the machine can track the seam accurately and ensure a high quality finished product.

VisionGauge® machine vision software and systems are well-suited to various semiconductor inspection and measurement applications, including polishing pad inspection, hybrid inspection, epoxy underfill measurement, substrate inspection, wafer defect detection, line, trace width and other semiconductor feature measurements, and much more.

Semiconductor Epoxy Underfill Measurement

VisiongGauge(r) OnLine Automated Optical Inspection (AOI) systems can accurately measure epoxy underfill - Pass or Fail

In the electronic device manufacturing industry Epoxy resin is used as an adhesive or as an insulator on the component layer of PCB boards. Inspecting the presence and assuring the right amount of epoxy is present is a very important part of the quality assurance process. Our VisiongGauge® Online Automated Optical Inspection (AOI) systems are being employed to automatically detect the presence of semiconductor epoxy underfill on electronic devices, between a high-density circuit and its substrate, during the assembly process. VisionGauge® OnLine also accurately measures the under-fill’s “footprint” (i.e. maximum dimensions along the X and Y axes). This is carried out in-process, right after the dispensing and placement operations.

These systems are highly capable when dealing with great magnification, and they posses accuracy up to 0.1 micron. These systems are fully automated and can be programmed to move in a three-dimensional set of coordinates. Furthermore, you can use the system manually with the help of a joystick through our easy to use VisionGauge® Online machine vision software.

semiconductor automatic defect detectionIn one example, VisionGauge® OnLine is applied in semiconductor defect detection by a printer manufacturer to automatically review stored sequences of images and find any defects that might be contained in the images. In this application, the images are of various semiconductor products produced by this manufacturer. VisionGauge® OnLine can be asked to handle sequences of up to 22,000 images in a single run.  This is not a problem for VisionGauge® OnLine as there are no limits to the number of images that it can handle.  VisionGauge® OnLine is initially trained using “known good” images of the various types of products to inspect.  It is then automatically detects defects and non-conformities. Images that VisionGauge® OnLine characterizes as “good” are ignored and “bad” images are collected for operator review and corrective action. Statistics of VisionGauge® OnLine’s analysis are also collected (i.e. defect rate, etc…)

Robotic Control Software – Robot Guidance and Positioning Applications

As production lines become increasingly more automated, the need for precision robotic aid has become necessary. Our VisionGauge® OnLine machine vision systems can provide accurate robot positioning and guidance. They can operate the robot directly, in response to a visual inspection through Digital I/O signals, or (more recently developed) through TCP/IP or COM communications linked through the VisionGauge® OnLine software.

Robotic arms are the most used robotics application in the production line. Our systems can work to position the robot based on an inspection of the arm’s working area, or they can be embedded on the robotic arm for on-the-fly guidance and positioning.

Our systems also have full encoder support and can deal with resolutions up to 0.1 micron. All of our systems are powered by our versatile and easy-to-use VisionGauge OnLine machine vision software which contains such features as:

Automated Measurements in an Off-line Sampling of Injection Molded Parts

Automated measurements in medical device inspection

VisionGauge® Online is frequently employed to solve a wide variety of medical device inspection applications, often involving multiple measurement requirements. In one example, an application involves taking a number of different automated measurements in an off-line sampling of injection molded parts. Because the part-to-part position & orientation is variable, VisionGauge® Online first aligns – or “squares up” – the part with a master image. Then numerous measurements are automatically performed on the aligned image using VisionGauge® Online’s versatile measurement toolset. All of the measurements are compared to individual tolerances to determine if the part is within specifications. Results of the measurements are also collected and analyzed in VisionGauge Online’s Data Groups. Additionally, Data Group values are easily transferred to Microsoft Excel through Dynamic Data Exchange (DDE).
