使用机器视觉设备取放 – 优点
摄像头安装方式灵活
没有两个相同的应用!根据应用情况,可以将机器视觉硬件静态安装在抓取区域上方或直接安装在机械手臂上。摄像头的静态安装特别适用于空间紧张的应用或安装空间有限的小型机械手臂,将摄像头安放在机械手臂上可以提高应用的灵活性。

摄像头与机器人直接通信
2D 摄像头通过机器人视觉接口直接与制造商 UR、 KUKA 和 ABB 的机器人通信 – 无需开发自己的接口,也不必连接单独的硬件。每种类型的机器人都有示例程序或 UR 的 URCap 以供下载。这样可以非常简便快速地设置机器人视觉应用 – 无论是使用 B60 Smart Camera 还是带有机器视觉照相机的机器视觉控制器。记录的 TCP/IP 通信可与其他制造商连接。

Seamless Integration into the uniVision Ecosystem
The wenglor uniVision 3 toolbox offers various modules for object detection, such as the modules for localization and pattern matching. Both modules enable different object types to be taught in, whereby several – even different – objects can be found in both modules and sorted, for example, by position. Variable offsets in x and y can also be implemented, which increases the flexibility of the pick-and-place application enormously: Depending on the application, it is thus possible to specify the exact point at which the robot should grab the object – at the tip, in the middle or rather at the rear. The results, such as the gripping position or the contour of the detected object, can be displayed individually and flexibly in the web-based visualization.

Reduced Cycle Times Thanks to Multi-Object Recording
In wenglor uniVision 3 software, several – even different – objects can be detected with a single image capture and their coordinates can be passed on to the robot control system. This means that the robot can grip the objects directly one after the other without having to move to the detection position for camera capture again before each grip. This reduces cycle time and greatly increases the efficiency of the pick-and-place application.

Precise Calibration with Accurate Calibration Targets
The 2D camera and robot must initially be calibrated once. Highly accurate calibration targets are available in various sizes and materials (glass for transmitted light applications, carbon fiber for incident light applications). The successful calibration process can be checked directly via a verification step.

Pick and Place versus Bin Picking – What is the Difference?

Pick and Place: Precise Localization and Picking
In pick-and-place applications, 2D cameras locate the objects to be picked and pass their position coordinates on to the robot controller. The robot can then pick the objects precisely and then place them in a different position.
Pick and place is suited for simple and quick applications where the objects are separated and on one level.

Bin picking: Reaching into a Bin
Bin picking refers to an automated application, where robots pick randomly arranged objects from containers. This requires 3D sensors that detect the position of the objects in the space and pass the information to the robot.
Bin picking with 3D sensors is ideal if the objects are not separated and are arranged in random positions.
