[0002] With the improvement of industrial automation, manipulators play an increasingly important role in production lines. Manipulators are mechanical devices used in automated production lines, often used for tasks such as handling, assembly, and assembly. Their output ends are usually equipped with vacuum suction cups for grabbing and moving workpieces. The vacuum suction cups generate negative pressure to extract the air adsorbed on their surfaces, thereby generating adsorption force, allowing the manipulator to firmly grasp workpieces of various shapes and materials. This design is simple and reliable and is widely used in various industrial fields. However, during the processing of the workpieces, some workpieces will have a limiting protrusion structure on their inner walls. The existence of this limiting protrusion structure will bring difficulties to the demolding of plastic products.
