Automated weld seam in robot welding cells is a complex task in a harsh industrial environment. The micrometer-accurate detection of the guide point with different types of joint by 2D/3D profile is one of the most effective solutions for this challenge.

In combination with Wenglor’s uniVision software, the new weCat3D MLZL 2D/3D profile sensor not only combines the necessary precision and profile quality (1,280 points per profile), but also offers convenient installation, integration, robustness and is user-friendly. The working range is from 74 to 158 mm and the measuring range in X from 39 to 62 mm.

The slimline housing of the MLZL – with integrated cooling and rinsing – enable easy and space saving installation directly on the welding torch. With dimensions of only 33 x 183 x 69.8 mm, the robot can also operate in narrow corners. The sensor does not require any additional protection housing (IP67) nor does it need to be tilted for alignment. The design also offers sufficient protection against welding splatter and disturbing ambient light.

Optionally equipped with a red or blue laser, users can choose between three laser classes: 2M, 3R or 3B.  The MLZL relies on the advanced laser technology of the weCat3D series from Wenglor to deliver outstanding profile quality and optimal seam tracking.

Software uniVision 2.5.0 for Welding Applications

The configuration standard software uniVision receives a stand-alone module specifically for weld seam tracking. This means the welding applications can be set up in just a few clicks.

Due to the robust algorithms, tracking points can be reliably determined even in the event of faults in the joint course, such as with datum points. Predefined templates, where all common joint types are saved, significally reduce the configuration work. The result can be visualised on a web-based basis.

Several interfaces are available for direct integration into robot controls from Kuka, Fanuc, ABB, Kawasaki and Yasawa as well as their software.

The uniVision software is used to analyse images and height profiles in the field of industrial image processing. Two and three dimensional data from smart cameras, vision systems, smart 2D/3D profile sensors and IPCs with 2d/3D profile sensors can also be evaluated. Up to 25 different software modules and different templates are available to users in total depending on the selected hardware.

The new combination of software and hardware offers flexible solutions for every user. The most convenient and comprehensive system consists of a sensor, control unit with pre-installed uniVision software application and optional robot interface. There are also other combinations with or without control unit and customer-specific integration software which translates to Wenglor being able to offer the right solution to suit every individual requirement.
