Abstract

The invention discloses a rotary type pneumatic adsorption device and a delta robot. The rotary type pneumatic adsorption device comprises a pneumatic loop pedestal and a rotary shaft, wherein the rotary shaft passes through the pneumatic loop pedestal, and rotates relative to the pneumatic loop pedestal through a rotary bearing; a pneumatic sucking disc is fixedly arranged on the rotary shaft through a fixed pressure block; a gas path runner is arranged in the middle of the rotary shaft; a ring slot is formed in the rotary shaft; the diameter of the ring slot is smaller than that of the rotary shaft; at least one vent hole is formed in the ring slot; one end of the gas path runner is connected with an inner cavity of the pneumatic sucking disc; the other end of the gas path runner is connected with the vent hole; an air vent is formed in a position, which is opposite to the ring slot, of the pneumatic loop pedestal; sealing rings are arranged on the upper part and the lower part of the ring slot; a rotary bearing base is fixedly arranged at the periphery of the rotary bearing; and the pneumatic loop pedestal is fixedly arranged on the rotary bearing base. The rotary type pneumatic adsorption device disclosed by the invention is small in structural dimension, is strong in integration, avoids the possibility that a gas tube is wound in a rotary process of the sucking disc, and reduces extra load mass and load inertia at the tail end of the robot.

Description

technical field [0001] The invention relates to the technical field of robots, in particular to a rotary pneumatic adsorption device and a delta robot. Background technique [0002] Delta robots are used in light industries such as food and medicine, and replace manual labor in the production line to realize rapid sorting, sorting, packaging and other processes of materials. Its implementation is to install a pneumatic clamp or a pneumatic suction cup on the end effector of the DELTA robot, grab or suck the material for transportation and place it at a specified position at a specific angle. Especially for some materials with angle adjustment, after grabbing, it is necessary to rotate the grippers or suction cups to a certain angle according to the plane angle obtained by detection, so that they can be correctly put into the material tray or the designated process position. At this time, the pneumatic circuit will be entangled and knotted during multiple rotations. At the s...
