A device for enhancing the load-bearing capacity of a joint robot and its control method

Abstract

The invention discloses a device for reinforcing loading capacity of a joint robot. The device comprises a joint rotating shaft loading one-way moving device and a bearing chassis counterweight device; the joint rotating shaft loading one-way moving device includes an inner gear piece mounted on the outer side of a joint robot rotating shaft, a middle gear piece mounted with the joint robot rotating shaft and arranged on the inner side of the inner gear piece, and an outer gear piece arranged on the inner side of the middle gear piece; the outer gear piece is matched and mounted with a driving motor; the bearing chassis counterweight device includes a magnetic block mounted on one side of a bearing chassis; the magnetic block is parallel to a joint robot truss guide rail; and a powerful electromagnetic bar is arranged rightly below the magnetic block. The control method comprises the steps of: workpiece grabbing, balancing, lifting and emptying. The device for reinforcing loading capacity of the joint robot adopts a heightening accumulation mode to improve the drag loading capacity of a servo motor, and can balance the bearing chassis.

Description

[0002] Joint robot, also known as joint arm robot or joint robot arm, is one of the most common forms of industrial robots in today's industrial field; it is suitable for mechanical automation operations in many industrial fields, such as automatic assembly, painting, handling and welding. ; According to the structure of joint robots, it is classified into five-axis and six-axis joint robots, pallet joint robots and planar joint robots. Programming can complete fully automated work, improve production efficiency, controllable error rate, and replace many complex tasks that are not suitable for manpower and harmful to health, such as spot welding of car shells; due to the complicated working environment of joint robots, Therefore, its load-bearing capacity is required to be relatively good. The load-bearing capacity of existing joint robots can only be adjusted as a whole by adjusting the strength of the power mechanism, but the whole machine needs to be modified, and it is easy to cause rollover or damage the guide rail.
