uniVision 2.4 Image Processing Platform: Update Makes 2D/3D Profile Sensors Smart
The latest release of the modular uniVision image processing software has it all: While in the past an external analysis module always had to be used to evaluate 2D/3D profile recordings, the smart 2D/3D profile sensors now combine sensor and analysis module directly in the compact housing – thanks to uniVision 2.4. New overlays also provide even more user comfort and high-resolution digital cameras with 12 MP offer an even greater choice in the configuration of vision systems. All the 80 models in the weCat3D series can now also be used as a smart version, with no external analysis module (IPC) required. Both the profile recording and evaluation then take place directly in the sensor housing. The smart 2D/3D profile sensors show their full strength in particular in plants where space is at a premium. “At the same time, the quality of the profile data generated in the smart sensor remains the same. This new version, which is available with a software license update, is therefore ideal for applications with lower scan rates of up to 50 Hz, for example for angle measurement, but also for high profile quality requirements where highly reflective surfaces such as metals need to be reliably detected,” explains wenglor Product Manager, Martin Knittel. “Customers also save the cost of expensive IPCs for applications that do not require high IPC performance. For applications with high performance requirements, the solution with a separate control unit (IPC) is of course still available, offering maximum flexibility and easy interchangeability.” More Visualization Options for Greater Convenience The web-based visualization of the results will now include additional overlays in images and height profiles as part of the uniVision 2.4 release. With overlays such as boxes, cross-sectional areas, rectangles, polygons or images, results such as scanned codes, blobs or threshold images can be displayed directly in the image or profile. Additional texts such as code content, intersection point or angle information can be assigned to the overlays. Static images (e.g. logos) and OK/NOK images can also be displayed. New Digital Cameras With Higher Resolutions In addition to the existing digital cameras with a resolution of either 1.6 or 5 MP, there are now also high-resolution cameras available with 12 MP. Compatible with the C mount threaded connection, the new models are also available in either a color variant (color) or in a black-and-white version (monochrome). “The advantage of these digital cameras is that the very compact design offers a complete range of resolutions from 1.6 to 12 MP – but is used for the same mounting and connection technology,” says Knittel. “The high-resolution 12 MP cameras also display more details with the same visual field and the same focal distance.” There are a total of seven C mount lenses with fixed focal distances between 6 and 50 mm as suitable accessories for these cameras. Control Examples and Output Hold Time Make Operation Easier To make it easier to integrate all uniVision products into external control systems, sample programs will be available in future. There are examples for the Siemens’ TIA portal, Rockwell’s Studio 5000 Logix Designer, Beckhoff’s TwinCAT 3 and Omron’s Sysmac Studio, for example. The examples show integration via various standard interfaces such as PROFINET, EtherNet/IP, TCP/IP or UDP. For all digital outputs of the control unit, it is also possible to easily detect whether new results are available via the output hold time.

Scanner Performance Right Down the Line
wenglor Presents New Barcode Line Scanners Precision in the first dimension: wenglor’s new barcode line scanner sets new standards in the reading of one-dimensional codes. Thanks to the increased scanning area, the stationary scanner can be used even more flexibly – at manual workstations and in fully automated systems. With the integrated CCD line, the BLN series barcode line scanner sets itself apart in particular with its high reading performance. The large scanning area is 20 to 200 mm or 30 to 520 mm depending on the model, which greatly increases flexibility in system design and installation. The compact design (29 x 60 x 52 mm) also enables installation in tight spaces such as complex intralogistics facilities. The BLN scanner reliably reads 1D codes with a very high density of over 0.075 mm in static and dynamic applications of up to 0.3 m/s with a scan rate of 510 scans/s. The decoded information is sent directly to the system via an integrated Ethernet or RS-232 interface. Visible red light helps to ensure that the code is optimally aligned in the scanning area when used in manual workstations. The successful decoding is then output directly to the operator via a green “Good Read” LED, the practical OLED display shows the information stored in the code. In addition to the easy operating concept requiring no additional software, the smart sensor impresses with its robust housing design with IP67 degree of protection, which also makes it suitable for use in harsh industrial environments.

Automated Weld Seam Tracking: MLZL 2D/3D Profile Sensors
Automated weld seam tracking in robot welding cells is a complex task in a harsh industrial environment. The micrometer-accurate detection of the tracking point with different types of joint by 2D/3D profile sensors is one of the most effective solutions for this challenge. In combination with wenglor’s uniVision software, the new weCat3D MLZL 2D/3D tracker sensor not only combines the necessary precision and profile quality, but also offers convenient installation, integration, robustness and user-friendliness. A 2D/3D profile sensor made for welding robots: The slimline housing of the MLZL with integrated cooling and rinsing enables easy and space-saving installation directly on the welding torch. Thanks to the small housing dimensions of only 33 × 183 × 69.8 mm, the robot can therefore also operate in narrow corners. “The MLZL 2D/3D profile sensor does not require any additional protective housing, nor does it need to be tilted for alignment,” explains wenglor product manager Dr. Sascha Reinhardt. “The design also offers sufficient protection against welding spatter and disturbing ambient light.” Despite the harsh industrial environment, the welding sensor provides high-quality profiles for precise joint detection. 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 and thus delivers outstanding profile quality for optical seam tracking,” says Dr. Reinhardt. “This sensor has been specially adapted and optimized for the high demands in welding robots, but in particular for the complex task of optical tracking of weld seams – both in terms of hardware and software.” wenglor engineers tested and developed the special triangulation sensor as part of an EAP (Early Adopter Program) together with customers from the welding industry. The feedback and know-how collected from this program ultimately flowed into the MLZL tracker sensor. “We were able to incorporate many practical experiences directly into the development and thus obtained extremely precise information in advance about what is important in automated welding processes, where users face the greatest hurdles and what their wishes are.” Software Update with New Function: uniVision 2.5.0 for Welding Applications In its current update 2.5.0, the configurable standard software uniVision receives a stand-alone module specifically for weld seam tracking. For users, this means that welding applications can be set up in just a few clicks. “Thanks 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, significantly reduce the configuration work,” explains Dr. Reinhardt. The results can then be visualized on a web-based basis. Several interfaces are available for direct integration into robot controls from Kuka, Fanuc, ABB, Kawasaki and Yaskawa as well as their software. In concrete terms, this means: Welding processes can now be implemented with less effort, more functions and better results. The Welding Solution for Every User The new combination of software and hardware offers flexible welding solutions for every user. We always differentiate between applications with or without robot integration. The most convenient and comprehensive system consists of a sensor, control unit with pre-installed uniVision software application and optional robot interface. “For this purpose, the system was developed as a complete solution as part of the EAP. However, there are also other combinations with or without control unit and customer-specific integration software, meaning that we can offer the right solution to suit every individual customer requirement,” Dr. Reinhardt continues. That’s uniVision, the All-in-One Software The parameterizable uniVision standard software is used to analyze 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 (control units) 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.
