Power supply circuit of transfer robot

Abstract

The invention provides a power supply circuit of a transfer robot. The power supply circuit comprises an external power supply module, a voltage reduction and stabilization module and the transfer robot. The circuit is provided with a processing protection circuit, and the processing protection circuit comprises a filtering following circuit and a short circuit protection circuit; the filtering following circuit uses a resistor R1, a resistor R2, a capacitor C1, a capacitor C2, a resistor R4 and an operational amplifier U1A to filter a voltage signal, and uses a resistor R11, an inductor L1, adiode D3 and a capacitor C6 to select the voltage signal to filter amplitude reduction oscillation interference, and then the signals are transmitted to the transfer robot through a relay K1; a current transformer U2 in a short-circuit protection circuit is used for detecting the working current of a motor of the transfer robot, a triode Q2 and a triode Q3 are used for detecting current signals detected by the current transformer U2 respectively, and the triode Q2 is used for controlling the pin connection state of the relay K1; therefore, not only is the transfer robot protected, but also apower supply circuit of the transfer robot is effectively protected.

Description

technical field [0001] The invention relates to the field of robots, in particular to a power supply circuit for a handling robot. Background technique [0002] The development of technology has brought convenience to people's lives and simplified people's work. Before the development of technology, the repetitive and heavy handling work was done by humans, which is laborious and laborious. The existing technology has designed a handling robot to replace people. Complete repetitive heavy handling work. During the handling process, the robot uses battery power supply for power supply. However, due to the heavy workload of handling, it is also easy to have the problem that the battery power is insufficient and cannot continue to supply power during the handling process. [0003] In order to solve this problem in the prior art, an external power supply module is generally set up for the handling robot as a backup power supply for power supply. The external power supply module g...
