Description

Technical Field

[0001] This utility model relates to material transfer equipment, specifically, to a robotic gripper. Background Technology

[0002] In modern industrial automated production, robotic grippers, as end effectors, are widely used for material handling, transportation, and placement. Their performance directly affects the efficiency and reliability of the production line.

[0003] Currently, common robotic grippers are mainly divided into two categories: one is clamping grippers, such as pneumatic fingers and servo clamps, which grip workpieces through the opposing movement of two or more grippers; the other is suction grippers, such as vacuum suction cups, which pick up workpieces through suction force generated by negative pressure. In continuous processing steps such as injection molding, forging, and stamping, where the shape of the workpiece changes significantly, the production line usually needs to be equipped with two robotic arms with different functions, or a complex fixture changing system needs to be designed. The former leads to high equipment costs, large space occupation, and complex control; the latter will generate additional cycle time when changing fixtures, reducing overall production efficiency and failing to meet the needs of efficient and flexible automated production.
