Inspection of weld seams
with EyeSens Weld
The profile scanner measures the elevation profile of the weld seam by projecting a laser line onto the object. The laser line profile is then captured by the integrated camera. Additionally the evaluation software is already integrated in the camera.
EyeSens Weld can be applied wherever a weld seam also has to meet visual criteria, for example when it comes to externally visible component parts in industries such as the automotive industry, where no welding beads should be seen. In addition EyeSens Weld also inspects for the following criteria:
- if the weld has an end crater
- width and length of the weld seam
- it the weld seam is missing
- holes and surface pores on the weld seam
- unequal leg length
For this purpose the laser scanner of EyeSens Weld is mounted directly after the welding head. The scanner measures all drawn weld seams concerning surface and thickness. If necessary it can be initiated that e.g. the weld robot should make changes.
The EyeSens Weld system can be controlled - as all EyeSens 3D systems - via a web browser. The command for the control of weld seams is already prefabricated on the webinterface. For teaching in the program for a special object the user has to type the IP address of the camera into the web browser. The live image of the laser line from the profile scanner is then displayed with the webinterface in the browser. It is therefore not necessary to install a special software on the computer.
The laser line captured by the camera is transformed into electrical signals, digitized as well as converted into real world coordinates. The sensor has a frame rate of up to 1 Hz and a working distance of approximately 80 to 240 mm. The available wave lengths are 635 nm and 660 nm depending on the sensor model.
Therefore an easy-to-handle 3D weld seam inspection can be created.
EVT Eye Vision Technology GmbH
EVT - Eye Vision Technology develops the easy-to-program image processing software "EyeVision". Due to the drag-and-drop function, even users without programming skills can create inspection programms.
The EyeVision software is created for application in industries such as automotive, electronic, robotics, measurement technology, etc.
Additionally EVT also provides the right camera or smart camera such as EyeCheck or EyeSpector.
