Industrial robot contracting brake control system

Abstract

The invention relates to the technical field of industrial robots, in particular to an industrial robot contracting brake control system. The industrial robot contracting brake control system is applied to a robot body, the robot body is provided with a control part and a driving part, and the industrial robot contracting brake control system comprises a contracting brake base plate which is arranged on the robot body. According to the industrial robot contracting brake control system, the contracting brake base plate switches the on-off state of the circuit of the contracting brake base plate, so that the control part obtains or disconnects the control permissions of the driving part, all release systems of the contracting brake are integrated on the contracting brake base plate, the contracting brake control of six axes of a robot is realized through only one normally open reset switch, so that the number and space of switches are effectively reduced, in addition, the detection feedback to the contracting brake base circuit is added in the driving part, and the contracting brake control system can be operated under the condition of continuous power supply, so that the safety andworking efficiency are further improved.

Description

technical field [0001] The invention relates to the technical field of industrial robots, in particular to an industrial robot brake control system. Background technique [0002] For a long time, the brake function of the robot is to prevent the rotation of the motor shaft by the built-in brake of the servo motor, so as to prevent the robot from falling due to the influence of gravity in the case of a sudden power failure. It is considered to install an additional brake release control system on the control cabinet or the robot body. When the operator is trapped by the robot or the robot is in a strange posture and cannot be operated by the controller, the brake release system is required to release the motors of each axis. The brakes are used to promote the rotation of each shaft, thereby solving the above problems. [0003] In recent years, developers have optimized the brake release system of robots. For example, China Patent No. 201820850616.1 is an integrated control o...

Problems solved by technology

[0003] In recent years, developers have optimized the brake release system of robots. For example, China Patent No. 201820850616.1 is an integrated control of multi-joint brake release for industrial robots. The method of controlling six axes with three switches is realized through the decoding unit. However, the operation of this scheme is complicated, and the circuit cannot be effectively protected only by relays. In addition, the three switches for a robot with a small load will still take up a lot of space, such as an industrial robot with a Chinese patent application number of 201810529439.1 Brake release control circuit, increase the charging power to avoid the situation of no power supply to release the brake after power failure, however, increasing the charging power will lead to an increase in cost, and the charging power will also lose power. In addition, the designer also needs Consider how to place a charging power supply in a limited space

Therefore, it will cause great inconvenience
