Mesh grabbing

There are holes of varying sizes on the surface of the mesh, which poses a great challenge to traditional sensors. Traditional spot sensors may miss detection due to holes or make false detections due to complex colors during detection. Therefore, choosing a sensor with large spot background suppression has become the key to solving this problem.

Scenario requirement - detection of mesh

The robotic arm needs to use sensors for non-contact detection to determine whether the mesh is in place before suction, and trigger a signal to drive the robotic arm to grasp the mesh;

Selection analysis: 1. Require installation distance within 70MM; 2. The mesh holes vary in size and require a relatively large sensor spot; 3. There are many colors of mesh fabric, and sensors are required to be compatible for detection.

solution

Choosing a photoelectric sensor with large light spot and background suppression function is the best choice for the diverse colors and varying hole sizes of mesh fabrics. This type of sensor can cover a wider area, effectively distinguish the target object (mesh) from the background, and improve the accuracy and stability of detection. It is recommended to choose a photoelectric sensor with large light spot and background suppression function. For example, the Meiji ESB-BL10 series line spot background suppression photoelectric sensor or the ESB-B30 series large spot background suppression photoelectric sensor are both suitable for such complex detection scenarios.

1. Large light spot design: Meiji ESB-BL10 series linear light spot photoelectric, with a light spot length of 65mm; ESB-B30 series large light spot photoelectric has a maximum diameter of 300mm; the large light spot can cover a wider area, even in the case of many holes on the mesh, ensuring that some light spots always fall on the mesh, thus avoiding missed detection.

2. Background suppression function: Background suppression technology can effectively distinguish between target objects (mesh) and backgrounds (such as equipment frames, floors, etc.), and can accurately identify mesh even in environments with complex colors and large changes in lighting.

3. High precision detection: The sensor has high-precision optical signal analysis capability, which can distinguish the holes on the mesh from the actual existing mesh parts, ensuring the accuracy of detection.

4. Stable and reliable: Meiji uses high-quality optoelectronic components and advanced signal processing algorithms to ensure the stability and reliability of sensors during long-term operation.
