Description

Technical Field

[0001] This utility model relates to the field of parts retrieval technology, specifically to an online fractal parts retrieval device. Background Technology

[0002] In industrial automation, robotic arms are typically used for multi-station workflows and operations in confined spaces. These robotic arms usually have multiple suction cups, which need to be connected to an air pump via air hoses, resulting in long-distance air transmission. This poses significant challenges to the fixture design. Traditional pneumatic fixtures rely on external air sources and air hose connections, which have limitations such as low flexibility, complex pipeline maintenance, and high energy consumption. The main problems with fixture design for multi-station workflows and confined spaces are as follows:

[0003] 1. Space adaptability: Traditional pneumatic clamps require reserved space for pipeline layout due to the air pipe connection, making them difficult to deploy in narrow cavities or dense equipment groups, and may even lead to redundancy in production line design.

[0004] 2. Dynamic Flexibility: In multi-station scenarios, fixtures need to frequently change position and posture. The physical constraint of the air tube can easily cause motion interference, reducing production efficiency.

[0005] 3. Accuracy and stability: The workpiece positioning error tolerance is high in a confined space, but the pneumatic system is prone to clamping force deviation due to air pressure fluctuations.

[0006] Therefore, in order to reduce the burden on robots and improve their movement speed, existing picking technologies need to be further designed. Utility Model Content
