Embodiment 1

[0022] Such as figure 1 As shown, the power supply 10 with power-off protection function for supplying power to the robot controller 20 provided in this embodiment includes a power conversion circuit 1, a controller power supply module 2, a grid voltage detection module 3, and an energy storage module 4. The controller power module 2 is connected to the output terminal of the power conversion circuit 1 and supplies power to the robot controller 20. The grid voltage detection module 3 is connected to the power conversion circuit 1 to detect the input voltage of the power conversion circuit 1. When the input voltage of the power conversion circuit 1 is lower than the set threshold, the power supply 10 with power-off protection function outputs a power-off trigger signal S To trigger the robot controller 20 to perform power-off storage. The energy storage module 4 is connected to the controller power module 2, and stores energy when the power conversion circuit 1 is working normal...

Embodiment 2

[0036] This embodiment is basically the same as the first embodiment and its changes, the difference lies in: image 3 As shown, the network voltage detection module 3 is independent of the branch power supply module 5. A control switch 6 is provided between the power conversion circuit 1 and the branch power module 2, and the network voltage detection module 3 outputs the power-off trigger signal S and turns off the control switch 6 at the same time.

[0037] When the input voltage of the power conversion circuit 1 is normal, the control switch 6 is closed, and the power conversion circuit 1 supplies power to the branch power supply module 5 and the controller power supply module 2, and the circuit is in normal operation; at the same time, the power conversion circuit 1 The input voltage charges the capacitor C1. When the switch K on the input side of the power conversion circuit 1 is suddenly turned on or the input voltage is unstable so that the input voltage is less than the...

Abstract

The invention provides a power supply with a power-off protection function. The power supply is applied to a robot controller and comprises a power supply conversion circuit, a controller power supplymodule, a network voltage detection module and an energy storage module, wherein the controller power module is connected to the output end of the power conversion circuit and supplies power to the robot controller; the network voltage detection module is connected to the power supply conversion circuit to detect the input voltage of the power supply conversion circuit, and when the input voltageof the power supply conversion circuit is less than a set threshold value, the power supply with the power-off protection function outputs a power-off trigger signal to trigger the robot controller to perform power-off storage; the energy storage module is connected to the controller power supply module, and the energy storage module stores energy when the power supply conversion circuit works normally; when the input voltage of the power supply conversion circuit is less than the set threshold value, the energy storage module outputs energy to enable the controller power supply module to work normally, and the controller power supply module supplies power to the robot controller to enable the robot controller to complete data storage.

Description

Technical field [0001] The invention relates to the field of industrial robots, and in particular to a power supply with power-off protection function. Background technique [0002] At present, industrial robots have been widely used in production. With the continuous expansion of their application range, people have higher and higher requirements for the performance of industrial robots. This requirement ranges from the degree of intelligence and control accuracy of the robot. The aspect gradually expanded to the security of robot data storage. [0003] In the robot control system, the robot's operating procedures and control methods are realized by the operating system in the robot controller. During the execution of the robot, when the power supply of the robot controller is disconnected, the operating system and the robot controller program will be abnormally closed, which is very easy to cause the data in the operating system to be damaged. After the robot is restarted, the c...
