Deep learning-based image analysis
Localization and identification of distorted characteristicsViDi BLUE Locate finds complex features and objects by learning from annotated images. Self-learning algorithms locate parts, count translucent glass medical on a tray and perform quality control checks on kits and packages. To train the ViDi BLUE Locate tool, all the operator needs to provide are images on which the relevant features are marked.
Application example spark plugsFor certain identification, counting and classification applications, manufacturers must rely upon visual inspection when their environments do not support bar code reading technology. However, slight variations in appearance can cause problems for machine vision inspection systems.
This is the case with spark plugs, which arrive for pre-assembly on differently coloured trays. ViDi BLUE Locate and GREEN Classify identify, count and classify the spark plugs based on their appearance ready for packaging and pre-assembly inspection.
Defect detection and segmentationViDi RED Analyze is used to identify anomalies and aesthetic defects, be they scratches on an embellished surface, incomplete or improper assemblies and even weaving problems in textiles. This tool set can identify all these problems very simply by learning the normal appearance of an object, including any significant but permissible variations.
ViDi RED Analyze is also used to segment areas of special interest such – as the presence of foreign material on a medical fabric. The Analyse tool can reliably identify the relevant area simply by learning the varying appearance of the targeted zone.
Further application examplesViDi RED Analyze simplifies the automatic detection and classification of defects on textured metal surfaces, as in the inspection of piston rings. During cylinder inspection, the tool also reliably detects pores in the metal.
Automotive manufacturers must double and triple check all safety-critical components to ensure quality and reduce warranty and re-call costs.
Classification of objects and scenesViDi GREEN Classify is used to classify an individual object or a complete scene, be it the identification of products based on their packaging, the classification of weld seam quality or the separation of acceptable from unacceptable anomalies.
The tool learns to distinguish between various classes based on a collection of images. All that is required for the learning-in process are images assigned to and labelled in accordance with the various classes.
Piston weld seams are highly variable, making anomalies difficult to identify. Certain anomalies, such as
missing, overpowered or underpowered weld seams, are undesirable. However, other anomalies, including
overlapping seams, are desirable and even essential for safety reasons. The ViDi RED Analyze tool, in
combination with ViDi GREEN Classify, simplifies the automatic inspection and classification of weld seam
Reading text and charactersViDi BLUE Read deciphers badly deformed, skewed and poorly etched characters using optical character recognition, OCR. The pre-trained font library identifies most text without additional programming or font training, delivering a quick and easy application. This robust tool can be trained to adjust to specific OCR application requirements. No special expertise is required for this.

Application example: decoding chassis identification numberAutomotive manufacturers must be able to locate and decode chassis or vehicle identification numbers (VIN) for successful traceability. Paint colours, specular effects and glare make it difficult for traditional machine vision systems to locate and recognize characters. ViDi BLUE Read, however, reliably identifies all deformed characters during the VIN inspection.
SummaryArtificial intelligence (AI) and deep learning open up a new range of applications for vision technology. Complex challenges that were once impossible can now be reliably solved, particularly if unfamiliar anomalies are involved. The complexity of a difficult application is no longer an insurmountable problem: The Cognex ViDi Suite solves complicated applications simply and quickly, even without relevant AI expertise. ▪ ds
EtherCAT-P is a further development of the worldwide established EtherCAT technology. The special feature of
EtherCAT-P is the combination of the super-fast EtherCAT communication with the 24 V power supply. Data and
power (Us) for system and sensor supply with 24 V and 3 A are provided on a two-wire pair.
A second pair of wires provides data and the peripheral voltage (Up) for supplying the actuators. The direct coupling of the supply voltage to the 100 Mbit line enables a compact and cost-effective device connection.
CONEC currently offers shielded axial overmoulded designs with cable quality G6, TPU 4xAWG22, available in standard lengths. For the 100 MBit device connection almost exclusively male-male patch cords are used. Field attachable connectors are available as female and male variants in axial design, either with screw (female and male connector) or crimp (male connector) termination. Flanges for direct PCB mounting are available for the device connection. The continuous shielding from the flange housing to the circuit board is realized with a punched sheet metal plate. Moulded contact tongues form the radial connection to the flange housing. A special flange version with moulded cable and a further plug on side B, preferably P-coded, is suitable for wiring through the wall of a switch cabinet, for example. ▪ ds

Pick-to-Light solution for industry and intralogistics
PICK-TO-LIGHTFor Pick-to-Light solutions, the compartment displays are equipped with four numerical, digital, seven-segment displays and a touch button with a bright multi-colored lamp. The production information system signals with a colored illuminated touch button to which storage location the picker should go. The light is easily visible from a long distance, ensuring efficient forward planning for the picking sequence. The numerical display tells the picker how many parts are to be removed there and in which compartment the parts are to be placed on the accompanying, unmanned, automatic guided vehicle. The employee acknowledges the removal process by pressing the touch button. A color change signals an error and at the same time guides a second picker. An industrial truck then transports the parts to the assembly line where they are taken out of the respective compartments or containers. The collaborative solution raises productivity by avoiding errors in picking.
Put-to-LightThe Put-to-Light solution is identically constructed and is used in the filling area for empty containers. The functionality is similar to that of the Pick-to-Light solution. In this case, the product information system sends a command to fill up the container. The container is displayed via the illuminated touch button and the number of parts to be filled via the numerical display. Pressing the touch button concludes the process. Alternatively, automatic acknowledgement can be set up for Pick-to-Light and Put-to-Light, whereby an external sensor is connected to the compartment display via the M8 connection. It automatically detects removal or filling and immediately sends confirmation to the production information system. This option helps lower the error rate further. The Pick-to-Light and Put-to-Light solutions from Weidmüller allow improved handling of the supply process and significantly optimized productivity.
Robust compartment displaysThe compartment displays from Weidmüller feature a special property, are configured to be very robust with IP54 protection and IK05 impact protection, and also offer very good EMC resistance for use in industrial environments. The compactly designed displays with dimensions of 180x70x75 mm (length x width x height) can be installed without tools in next to no time. Together with the junction boxes available as accessories, the customer can achieve a decentralized device architecture with almost all communication structures and bus systems, including Modbus/TCP, PROFINET, EtherCAT and EtherNet/IP.
ConclusionThe Pick-to-Light solution from Weidmüller allows the timely provision of required parts and tailored support for manual work in industry and intralogistics, with reduced error rates and significantly improved productivity. ▪ ds

Robot systems: workpiece handling with vision
Flexible loading and unloadingThe same is true of positioning. The more accurately the workpiece has to be placed, the more demanding the requirements put on the vision system.
Placement on a conveyor belt is simple; positioning within a machine tool is challenging. The more flexibility required for loading and unloading a workpiece (into and out of the machine), the more complex the system.
New vision systems
Liebherr works with a selection of three different variants chosen specific to the requirements. A red light
laser is used in 3D vision systems that use a laser time-of-flight method. It offers a highly robust solution
that is separate from ambient light conditions and the level of contamination. An alternative is to use a 3D
vision system using a precise two-stage laser triangulation process with a blue light laser. This type of system
is ideal for workpieces made of metal, organic and semi-transparent or reflective materials. The third option is
the highly-flexible 3D stereo vision system with a triangulation process and supported by an additional
projector unit. This option is perfect for short cycle times. The 3D stereo vision system can create complete
and homogeneous depth maps of the scene using special projector technology.
for bin picking
Process-safe emptying of containersAs a result, it provides fast and high-resolution image recognition. This allows a robot with patented additional axes to empty transport containers up to one meter in depth with process precision.
Optical detection occurs within five seconds, depending on the vision system and the associated evaluation. That enables short cycle times for the overall system.
Thanks to the high resolution, the data cloud interface is smooth and virtually noiseless. These high-quality measured values are transmitted to the main software of the bin picking system. The software enables easy teaching of workpieces, grippers and their grip points. ▪ ds
