Title:
AUTOMATIC LUBRICATION SYSTEM FOR INDUSTRIAL ROBOT JOINT
Document Type and Number:
WIPO Patent Application WO/2022/252339
Kind Code:
A1
Abstract:
The present invention relates to the technical field of industrial robot joint apparatuses, in particular to an automatic lubrication system for an industrial robot joint. The automatic lubrication system comprises a chassis, a turntable base, a turntable shaft, a first joint, a second joint, and a joint shaft which is hinged for rotation, wherein a rotating shaft is fixedly mounted at the bottom of the turntable base. In the automatic lubrication system for the industrial robot joint, a first automatic lubrication mechanism and a second automatic lubrication mechanism are configured in such a way that when the turntable base rotates or the first joint and the second joint are in rotation operation, a first push rod and a second push rod are driven to work, and the suction or pressure generated inside a first lubrication pipe and a second lubrication pipe is controlled, such that lubrication oil in a first oil storage pipe and a second oil storage pipe is automatically controlled to flow out from a first applying pipe and a second applying pipe, in order to perform the applying operation on the turntable shaft and the lubrication operation on the joint shaft; and in this way, the lubrication oil can be injected in time, the lubrication efficiency is enhanced, joint wear is avoided, and the service life is prolonged.
