Vacuum adsorption type mechanical arm

The invention relates to a vacuum adsorption type mechanical arm. The vacuum adsorption type mechanical arm comprises an adsorption device, an up-down reciprocating motion module, a front-back reciprocating motion module and a left-right reciprocating motion module, wherein the up-down reciprocating motion module, the front-back reciprocating motion module and the left-right reciprocating motion module are used for driving the adsorption device to do up-down, front-back and left-right reciprocating motion. The left-right reciprocating motion module is installed on the front-back reciprocating motion module, and the up-down reciprocating motion module is installed at the right end of the left-right reciprocating motion module. The adsorption device is arranged on the lower portion of the up-down reciprocating motion module. By means of the vacuum adsorption type mechanical arm, mechanical arm-assisted flow line production in the three dimensions of front-back, left-right and up-down can be conducted, and full-automatic production is realized. Working efficiency is high, labor intensity is low, labor cost is reduced, and economic benefits are increased.
