Power outage self-protection method of industrial robot and industrial robot achieving power outage self-protection method

Abstract

The invention relates to a power outage self-protection method of an industrial robot. The power outage self-protection method comprises the following steps that an inverter converts the electrical energy of a power storage device into the normal power supply after an external power source of a system is disconnected, and a motor drives a manipulator and a parking and storing mechanism to move until the tail end of the manipulator is moved to the parking and storing mechanism. The invention further relates to the industrial robot achieving the power outage self-protection method. The industrial robot includes a machine body and an electrical cabinet which are connected with a bracket; the machine body comprises the manipulator and the servo motor; the electrical cabinet comprises a servo motor driver and a controller; the servo motor is connected with the controller through the servo motor driver; the industrial robot further includes the parking and storing mechanism connected to thebracket, the power storage device and the inverter, wherein the power storage device and the inverter are arranged in the electrical cabinet; and the inverter converts the electrical energy of the power storage device into the normal power supply after the external power source of the system is disconnected, so that the tail end of the manipulator is moved to the parking and storing mechanism. Bymeans of the power outage self-protection method and the industrial robot, the cost is reduced, and the manipulator is prevented from hitting a platform in the event of power outage.

Description

technical field [0001] The invention relates to an industrial robot, and also relates to a power-off self-protection method for the industrial robot. Background technique [0002] The Delta robot is a high-speed, light-load parallel robot. It generally captures the target object through teaching programming or a visual system. Three parallel servo axes determine the spatial position of the gripper center (TCP) to realize the transportation and processing of the target object. . Delta robots are mainly used in the processing and assembly of food, medicine and electronic products. Delta robots are being widely used in the market due to their light weight, small size, fast movement speed, precise positioning, low cost and high efficiency. [0003] The motors used by existing delta-type robots are basically servo motors with brakes, but the cost of such motors is relatively high; using servo motors without brakes can save costs, but delta-type robots will Finally, the entire ...

[0003] The motors used by existing delta robots are basically servo motors with brakes, but the cost of such motors is relatively high; using servo motors without brakes can save costs, but the delta robots will Finally, the entire arm will suddenly fall due to its own weight. After falling, the robot arm will hit the platform where the servo motor is installed, which will easily cause damage to the robot arm.
