Rotation lifting mechanism of horizontal joint robot

Abstract

The invention relates to a rotation lifting mechanism of a horizontal joint robot, wherein the upper end of a hollow shaft is connected to a forearm belt conveyor, and the other end is inserted into arotation cylinder; an electric conduction slide ring sleeves the rotation cylinder, a rotation motor is installed on a shell and is connected to the upper end of an inner rotation part of the electric conduction slide ring by a rotation transmission mechanism, the lower end of the inner rotation part is connected to the rotation cylinder, an outer fixation part is fixedly connected to the shell,and a lip-shaped seal ring is disposed under the electric conduction slide ring; an upper press ring is installed on the inner rotation part, a lower gasket is relatively fixed to the rotation cylinder, and a seal flexible ring is disposed between the upper press ring and a lower press ring; and a lifting motor is installed on a forearm and is connected to a lifting part by a lifting transmissionmechanism, a lifting part is driven to drive the rotation cylinder to realize ascending and descending relative to the hollow shaft, and dynamic sealing is realized between the rotation cylinder and the hollow shaft by the upper press ring, the seal flexible ring and the lower gasket. The mechanism provided by the invention can facilitate miniaturization of a joint speed reduction mechanism, facilitate joint sealing and facility increase of a cleanliness grade of equipment.

Description

technical field [0001] The invention belongs to the field of robots, and in particular relates to a rotary lifting mechanism of a horizontal joint robot, which is suitable for an upper screening robot system and can be used in the automatic upper screening link of wine production. Background technique [0002] The Shangzhen robot system is used for the automatic Shangzhen link application in the wine industry and is an important part of the overall project. Since the screening robot system is one of the components of automatic screening equipment, it needs to cooperate with the mixer, conveyor, automatic switch screening pot cover, automatic steam control system, etc. to complete a complete set of automatic wine screening and distillation work. The Shangzhen robot system includes a four-axis main robot system, a large and small arm and end feeder system, an infrared sensor system, and an ultrasonic system. During specific work, the four-axis robot joint is responsible for re...
