A waterproof cleaning robot

Abstract

The invention relates to a waterproof cleaning robot. A rotating cylinder is rotatably installed on a base. One end of a large arm is connected to the rotating cylinder, and a joint driving device is installed at the other end. One end of the joint connecting cylinder can be relatively rotatably inserted into the other end of the large arm. And connected with the joint drive device, the other end of the joint connection cylinder is plugged into the inside of one end of the forearm; the boom rotates with the rotation cylinder, the joint connection cylinder and the forearm have the degree of freedom of rotation with the boom, and also have the degree of freedom of rotation; The arm air supply pipeline is spirally wound on the joint connection cylinder, one end communicates with the inside of the rotation cylinder, the other end is inserted into the joint connection cylinder, and communicates with the diverter plate set in the joint connection cylinder, and the forearm air supply pipeline is multiple , one end is connected to the diverter plate; between the other end of the big arm and one end of the forearm there are a plurality of air cavities evenly distributed along the circumferential direction, and each air cavity communicates with the other end of an air supply pipe for the forearm. The invention has good waterproof effect, is clean and dust-free, and improves the dynamic performance of the robot.

Description

technical field [0001] The invention relates to a robot in the cleaning, flat panel display and integrated circuit industries, in particular to a waterproof cleaning robot. Background technique [0002] Flat panel display (FPD) is another large-scale industry developed after integrated circuit (IC). The glass substrate is one of the key basic materials of the FPD industry, and the manufacturing process of the FPD industry requires a high degree of automation and unmanned operation. Therefore, handling robots have been introduced into the FPD industry to achieve smooth handling and precise positioning of glass substrates. [0003] There are many stations of the glass substrate handling robot that require the robot to be waterproof, and the protection level is IP54 ("5" means completely preventing the intrusion of foreign objects. Prevent water splashed from all directions from invading electrical appliances and causing damage.) The water splashed by the robot contains vario...

AI Technical Summary

Problems solved by technology

Dust will be generated after drying in areas with and without water; conventional contact seals for robot joints will cause friction and dust; conventional contact seals for robot joints will generate random joint resistance, which will affect the dynamic performance of the robot
