AI Technical Summary

Technical Problem

Traditional octopus-shaped suction cups are unstable and prone to air leakage when gripping objects with uneven surfaces or surfaces with particles, and they are also prone to deformation and detachment when moving at high speeds.

Method used

The suction cup body is sealed with a concave annular gasket, and the circumferential vacuum channels are evenly distributed, with negative pressure concentrated at the edge. The concave annular gasket is integrally molded with the suction cup body and made of silicone material to form a double-lip seal to reduce air leakage. The vacuum interface is connected to an external generator.

Benefits of technology

It improves the gripping effectiveness and sealing of suction cups on uneven surfaces, reduces the probability of air leakage, prevents detachment, and is suitable for high-speed movement of robotic arms.

Abstract

The utility model discloses an anti -leakage mechanical arm adsorption device of octopus sucker structure belongs to robot end effector technical field, anti -leakage mechanical arm adsorption device of octopus sucker structure, including the main part of sucking disc, the bottom edge of main part of sucking disc is provided with the recessed ring gasket, and the recessed ring gasket forms the closed annular package to the edge of main part of sucking disc, and the periphery of main part of sucking disc is annularly distributed with the circumferential vacuum passage, and the circumferential vacuum passage is evenly equidistant distribution, and is provided with vacuum interface on main part of sucking disc. It can guarantee the effectiveness of the capture when the main part of sucking disc acts on the object with the surface concave and convex such as the woven bag, also can effectively guarantee the sealing effect when adsorbing in the face of the particle existing on the adsorption surface, simultaneously, the possibility of air leakage of main part of sucking disc is little when adsorbing, and the negative pressure is concentrated, makes main part of sucking disc when facing the high -speed movement of mechanical arm, also not prone to the problem of deformation and falling off.
