MiniPick3D, IntelliPick3D, and Car Paint Vision

Share this on social media:

Isra Vision has released a compact sensor with quad-camera technology, which enables bin picking for even the smallest components. With its four cameras, the system scans the entire container volume, reliably recognizing small components even in the presence of glossy or coated surfaces. Furthermore, with its powerful LED lighting, the sensor achieves fast scanning times of under one second.

The MiniPICK3D sensor from ISRA VISION performs reliable detection and automatic picking of components with an edge length of just a few millimeters, such as plugs, injection-molded elements, electronic, or precision engineering components. Equipped with four cameras, the sensor ensures a comprehensive overview of every container at the required precision and speed. Small components are not just a challenge due to their small size. Their low weight also means that robot systems can move them very quickly over typically relatively short transport paths. This makes fast scanning times and precise object detection indispensable in order to enable optimal cycle times.

The quad-camera technology of the MiniPICK3D sensor uses four integrated cameras to scan the entire content of every container. MiniPICK3D is designed for bins with a volume of 300 x 200 x 150 mm in particular. The different viewing angles of the four integrated cameras enable several different perspectives of the same object. These multi-view images ensure that each component is reliably detected and picked, even under difficult conditions, such as shadowing or surface reflections. Moreover, due to its special embedded processor technology, the sensor achieves scanning times of just a few hundred milliseconds, regardless of the surface structure or the components to be detected. In a fraction of a second, its powerful LED lighting provides all the reference points required to detect the components to be picked reliably and at high speeds. Furthermore, several parts can be picked after a single scan, thus realizing additional time savings. In combination with collaborative robots, in particular, this opens up new applications for bin-picking solutions in a range of industry sectors, including assembly and logistics.

IntelliPICK3D

Isra Vision has also added two fully automated bin picking sensors to its range of IntelliPICK3D products. With an embedded PC, the sensor design completely eliminates the need for extensive wiring between the camera and the PC, ensuring data transmission at the maximum possible speed. Therefore, users benefit from faster data processing and extremely short scanning times. The individual design of the two systems focuses on high process reliability and maximum speed. With its multi-line laser illumination and optimum software extensions, the newly equipped IntelliPICK3D-PRO is particularly well-suited to difficult lighting conditions. The innovative PowerPICK3D, on the other hand, features quad-camera technology that achieves new top speeds, enabling scanning times in the millisecond range.

The IntelliPICK3D-PRO was specifically designed with highly demanding challenges on production lines in mind. Its powerful laser lighting ensures detailed image capturing with a high depth focus even at great distances from the container, in incident light, and other difficult conditions, while still being safe for the eyes. Even in complex locations, the system reliably detects and picks a wide range of parts with sizes ranging from 15 mm up to 2000 mm. The system detects dirty surfaces as reliably as glossy or matte components. It’s  intelligent collision avoidance feature automatically plans the correct picking path to ensure smooth operation. A new software extension now enables the system to tolerate different container positions and types, supplying the production line without interruptions and with high process reliability. 

Bin picking can now be performed at record speeds thanks to the quad-camera technology of the PowerPICK3D sensor. During this multi-stereo procedure, four integrated cameras capture the to be picked components in the container. Then, PowerPICK3D automatically creates an optimized picking sequence and calculates the corresponding robot paths. As the quad-camera assembly provides multiple camera angles, the sensor guarantees highly reliable multi-view image capturing, even under difficult conditions in the field of view, including shadowing or light reflections from component surfaces. Furthermore, the advanced point cloud generation covers the entire scanned surface quickly and precisely.

All bin picking solutions from ISRA are based on point cloud technology, which completely scans objects inside a container. The various sensors use a CAD template to extract the components to be picked from this initially unstructured information. Quick and efficient at learning new part geometries with the help of CAD datasets, the system can detect a virtually unlimited number of components. The systems are compatible with all standard communication interfaces and can be easily installed in any environment thanks to their flexible installation system. As part of the Touch & Automate portfolio, IntelliPICK3D-PRO and PowerPICK3D sensors are equipped with Wi-Fi as standard. This makes them ready for the future of industrial production and perfectly prepared for the requirements of INDUSTRIE 4.0.

Car Paint Vision system

Isra Vision also now offers its Car Paint Vision (CPV) system, a stationary or robot-mounted system that detects all topographical and non-topographical paint defects – such as inclusions, craters, bubbles, scratches, bumps, and dents – with precision down to the micrometer range, and documents and classifies them.

For the robot-mounted solution, four robots without linear axes are sufficient to scan the entire vehicle surface. The complete inspection of an entire vehicle often takes less than 50 seconds at top speed. Moreover, individually adaptable error reports allow immediate analysis of the identified defects. Furthermore, the intuitive operator software supports users in commissioning the system quickly by guiding them through setup step by step.

The heart of the CPV solution is the deflectometry sensor PAINTSCAN, which achieves short cycle times in both line tracking (on the fly) and the stop & go process. Equipped with embedded technology, PAINTSCAN does not need any external evaluation hardware. The high-resolution USB 3.0 camera technology is directly connected to embedded high-performance computing units, thereby enabling short scanning times. Its omni-directional, multi-channel LED lighting inspects with a detection rate significantly above 95%. Furthermore, thanks to redundant images (oversampling), specific tolerances can be defined for various parts of the car body in order to achieve precisely the desired quality. PAINTSCAN calculates the corresponding robot paths for the inspection using a CAD model, which considerably simplifies the setup of new vehicle models. Based on the digital model, defect coordinates can be displayed immediately and used for the color marking of defects with robots.
