[0037] Among them, the isolation transformer 10 can isolate the electrical connection between the primary side and the secondary side, and transmit the electrical signal of the primary side to the secondary side through the principle of electromagnetic induction to prevent the electrical signals of the primary side and the secondary side from interfering with each other; the first switch unit 21 and the second switch unit 22 include switch devices such as knife switches, which can be set according to actual needs, and are not specifically limited here. The robot load 60 includes a robotic arm trolley, a navigation trolley, an ablation trolley, etc., which can be designed according to actual needs, and are not specifically limited here. The first power supply terminal 31 and the second power supply terminal 32 can be provided by the AC power supply 30, or by other means, which are not specifically limited here.

[0038] Specifically, when the first power supply end 31 and the second power supply end 32 provide a first level of electrical signal, the first switch unit 21 and the second switch unit 22 in the switch module 20 are operated, so that the first input end ig1 of the first switch unit 21 is electrically connected to the first output end io1, and the second output end io2 of the second switch unit 22 is electrically connected to the second input end ig2, and the isolation transformer 10 can isolate the first level of electrical signal and transmit it to the robot load 60; when the first power supply end 31 and the second power supply end 32 provide a second level of electrical signal, the first switch unit 21 and the second switch unit 22 in the switch module 20 are operated, so that the first input end ig1 of the first switch unit 21 is electrically connected to the second output end io2, and the second output end io2 of the second switch unit 22 is electrically connected to the third input end ig3, and the isolation transformer 10 can isolate the second level of electrical signal and transmit it to the robot load 60, so that the robot load 60 works normally. In this way, the working gear of the isolation transformer 10 can be controlled by the switch module 20 to adapt to different application requirements, improve the practicality of the power supply control system of the robot and the working reliability of the robot load 60.

[0039] The technical solution of the present invention is to set a power supply control system of the robot including an isolation transformer and a switch module, wherein the isolation transformer includes a first end, a second end, a third end, a fourth end, a fifth end and a sixth end, the third end is electrically connected to the second power supply end, and the sixth end is electrically connected to the second power supply end of the robot load; the switch module includes a first switch unit and a second switch unit, the first switch unit includes a first input end, a first output end and a second output end, the first input end is electrically connected to the first power supply end, the first output end is electrically connected to the first end, and the second output end is electrically connected to the second end, the second switch unit includes a second output end, a second input end and a third input end, the second output end is electrically connected to the first power supply end of the robot load, the second input end and the fourth end are electrically connected, and the third input end is electrically connected to the fifth end ; By controlling the first input terminal in the first switch unit to be electrically connected to the first output terminal, the second output terminal in the second switch unit is controlled to be electrically connected to the second input terminal, so that the isolation transformer can process the electrical signal provided by the power supply end with the first isolation transformation ratio and transmit it to the power supply end of the robot load; or, by controlling the first input terminal in the first switch unit to be electrically connected to the second output terminal, the second output terminal of the second switch unit is controlled to be electrically connected to the third input terminal, so that the isolation transformer can process the electrical signal provided by the power supply end with the second isolation transformation ratio and transmit it to the power supply end of the robot load. In this way, the working gear of the isolation transformer can be controlled by the switch module to adapt to different application requirements, thereby improving the practicality of the robot's power supply control system and the working reliability of the robot load.

[0040] Optional, reference Figure 1When the first input terminal ig1 of the first switch unit 21 is electrically connected to the first output terminal io1, and the second output terminal io2 of the second switch unit 22 is electrically connected to the second input terminal ig2, the electrical signal received by the isolation transformer 10 is a first-level electrical signal; when the first input terminal ig1 of the first switch unit 21 is electrically connected to the second output terminal io2, and the second output terminal io2 of the second switch unit 22 is electrically connected to the third input terminal ig3, the electrical signal received by the isolation transformer 10 is a second-level electrical signal.

[0041] The first level electrical signal is different from the second level electrical signal.

[0042] Specifically, the first-level electrical signal is different from the second-level electrical signal, and the isolation transformation ratio of the isolation transformer 10 for processing the first-level electrical signal is also different from the isolation transformation ratio for processing the second-level electrical signal. The specific setting can be made according to the actual situation. For example, the first-level electrical signal is 240V, and the isolation transformation ratio of the isolation transformer 10 for the first-level electrical signal is 1:0.96. Compared with the isolation transformation ratio of 1:1 of the isolation transformer 10 in the prior art, it can avoid the problem that a large starting current is generated at the moment when the robot load is powered on, and a voltage drop is generated in the starting circuit, resulting in the robot load 60 cannot start or fails to start, thereby improving the starting reliability and timeliness of the robot load; the second-level electrical signal is 100V, and the isolation transformation ratio of the isolation transformer 10 for the second-level electrical signal is 1:1.1. Compared with the isolation transformation ratio of 1:1 of the isolation transformer 10 in the prior art, it can avoid the problem that the robot load fails or cannot start, and improve the starting reliability and timeliness of the robot load 60. In this way, by adjusting the isolation ratio of the isolation transformer, the isolation transformer can convert input electrical signals of different levels into power supply signals required for the robot load to work, thereby improving the reliability and practicality of the robot's power supply control system.

[0043] Optional, Figure 2 A schematic diagram of the structure of another power supply control system of a robot provided in an embodiment of the present invention, such as Figure 2 As shown, the power supply control system of the robot also includes an AC switch 11; the AC switch 11 is electrically connected between the first power supply terminal 31 and the first input terminal ig1 of the first switch unit 21; the AC switch 11 is also electrically connected between the second power supply terminal 32 and the third terminal i3 of the isolation transformer 10.

[0044] The AC switch 11 includes a knife switch or an isolating switch, etc., which can control the conduction or disconnection of the AC path and can be set according to actual needs. Figure 2 The AC switch 11 only includes a knife switch, and can also be other types, which are not specifically limited here.

[0045] Specifically, when the electrical signals provided by the first power supply terminal 31 and the second power supply terminal 32 are normal, the AC switch 11 can be controlled to close, so that the electrical signals provided by the first power supply terminal 31 and the second power supply terminal 32 can be transmitted to the isolation transformer 10 through the AC switch 11, and then transmitted to the robot load; when the electrical signals provided by the first power supply terminal 31 and the second power supply terminal 32 are abnormal or the first power supply terminal 31 and the second power supply terminal 32 cannot provide electrical signals or the robot load does not need power supply, the AC switch 11 can be controlled to disconnect to disconnect the electrical connection path between the power supply terminal and the isolation transformer 10, so as to prevent the abnormal electrical signal from being transmitted to the isolation transformer 10, causing unnecessary influence on the isolation transformer 10, thereby improving the reliability of the power supply control system of the robot.

[0046] Optional, reference Figure 2 The power supply control system of the robot also includes a first fuse FU1 and a second fuse FU2; the first fuse FU1 is electrically connected between the AC switch 11 and the first input terminal ig1 of the first switch unit 21; the second fuse FU2 is electrically connected between the AC switch 11 and the third terminal i3 of the isolation transformer 10.

[0047] Among them, the fuse FU includes an inserted fuse, a spiral fuse, a closed fuse, a fast fuse or a self-resetting fuse, etc., which can be selected according to actual needs and are not specifically limited here.

[0048] Specifically, when the current flowing through the fuse FU exceeds the specified value, the fuse FU itself can generate heat to cause the fuse FU to melt, thereby disconnecting the connection circuit between the AC switch 11 and the isolation transformer 10, preventing high current signals of short-circuit current or overcurrent from being transmitted in the power supply control system of the robot, thereby improving the safety of the power supply control system of the robot.

[0049] Optional, Figure 3 A schematic diagram of a power supply control system for a robot according to an embodiment of the present invention is shown in FIG. Figure 3 As shown, the power supply control system of the robot further includes a filter module 40; the filter module 40 is electrically connected to the first power supply terminal 31, the second power supply terminal 32, the first input terminal ig1 of the first switch unit 21 and the third terminal i3 of the isolation transformer 10 respectively.

[0050] Among them, the filter module 12 may include filter devices such as inductors or capacitors, and may be designed according to actual needs, which are not specifically limited here. Exemplarily, the filter module 12 includes an electromagnetic interference filter (EMI filter), which can effectively suppress the high-frequency noise in the electrical signal provided by the first power supply terminal 31 and the second power supply terminal 32 from entering the power supply control system, reducing the impact of the noise in the electrical signal provided by the power supply terminal on the power supply control system, and can also effectively suppress the noise generated inside the power supply control system from being transmitted to the outside world, reducing the impact of the power supply control system on the power supply terminal and other equipment.

[0051] Specifically, the filtering module 12 can filter the electrical signals input from the first power supply terminal 31 and the second power supply terminal 32 and input them into the isolation transformer 10, thereby eliminating disturbances caused by noise and other interferences, thereby reducing the ripple of the electrical signals output to the isolation transformer 10 and improving the accuracy and stability of the electrical signals.

[0052] Optional, Figure 4 A schematic diagram of a power supply control system for another robot provided in an embodiment of the present invention is shown in FIG. Figure 4 As shown, the power supply control system of the robot also includes a UPS module 50; the UPS module 50 is electrically connected between the second output terminal io2 of the second switch unit 22 and the first power supply terminal in1 of the robot load 60, and the UPS module 50 is also electrically connected between the sixth terminal i6 and the second power supply terminal in2 of the robot load 60; the UPS module 50 includes a DC charging and discharging unit 51, and the UPS module 50 is used to control the corresponding electrical signal output according to the electrical signal output by the isolation transformer 10 and the DC electrical signal of the DC charging and discharging unit 51.

[0053] The UPS module 50 can stabilize the electrical signal output by the isolation transformer 10 and transmit it to the robot load 60. The DC charging and discharging unit 51 includes a battery pack and the like.

[0054] Specifically, when the AC power supply 10 is supplying power normally, the UPS module 50 can transmit the electrical signal output by the isolation transformer 10 to the robot load 60, and when the UPS module 50 detects that the power level of the DC charge and discharge unit 51 is low, the electrical signal output by the isolation transformer 10 is transmitted to the DC charge and discharge unit 51, so that the DC charge and discharge unit 51 has more electrical energy, so that when the power supply at the first power supply terminal 31 and the second power supply terminal 32 is abnormal or power is cut off, the electrical energy in the DC charge and discharge unit 51 can be transmitted to the robot load 60, thereby ensuring the power supply reliability of the robot load 60.

[0055] It can be understood that when the UPS module 50 is electrically connected between the isolation transformer 10 and the robot load 60, the UPS module 50 acts as a direct load of the isolation transformer 10. The UPS module 50 can start normally when the isolation transformer 10 outputs a wider range of voltage signals. After the UPS module 50 is started, the electrical signal of the isolation transformer 10 can be stably transmitted to the robot load 60.

[0056] Optional, reference Figure 4 , the UPS module 50 includes an AC-DC conversion unit 52; the AC-DC conversion unit 52 is used to convert the AC power signal output by the isolation transformer 10 into a DC power signal and transmit it to the DC charge and discharge unit 51; or convert the DC power signal of the DC charge and discharge unit 51 into an AC power signal and transmit it to the robot load 60. In this way, by arranging the AC-DC conversion unit 52 inside the UPS module 50, it is prevented that the AC power signal output by the isolation transformer 10 is directly transmitted to the DC charge and discharge unit 51, thereby preventing the DC charge and discharge unit 51 from malfunctioning or abnormal, and preventing the DC power signal of the DC charge and discharge unit 51 from being directly transmitted to the robot load 60, thereby preventing the robot load from working abnormally, and other problems, thereby improving the reliability of the electric signal transmission of the power supply control system of the robot.

[0057] In an optional embodiment, the UPS module 50 also includes an overvoltage protection unit and an undervoltage protection unit, so that when the voltage of the electrical signal received by the UPS module 50 exceeds the rated voltage range of the UPS module 50, the overvoltage module or the undervoltage module will control the UPS module 50 to stop supplying power to the robot load 60 and issue an alarm, so as to improve the power supply safety of the robot's power supply control system.

[0058] Optional, reference Figure 4 The UPS module 50 also includes a heat dissipation unit 53; the heat dissipation unit 53 includes heat dissipation devices such as a fan, which is used to reduce the heat generated when the UPS module 50 is working.

[0059] In an optional embodiment, the power supply control system of the robot also includes a display module, which is electrically connected to the UPS module 50 and is used to display the output electrical signal of the isolation transformer 10 obtained by the UPS module 50, the power of the DC charging and discharging unit 51, and the working status of the AC-DC conversion unit 52, so that the staff can intuitively obtain the working status of the power supply control system of the robot.

[0060] Optional, Figure 5 A schematic diagram of a power supply control system for a robot provided in an embodiment of the present invention is shown in FIG. Figure 5As shown, the power supply control system of the robot also includes a controller 70; the controller 70 is electrically connected to the first power supply terminal 31, the second power supply terminal 32 and the switch module 20 respectively, and the controller 70 is used to control the conduction state of the first switch unit 21 and the second switch unit 22 according to the electrical signals provided by the first power supply terminal 31 and the second power supply terminal 32.

[0061] Specifically, when the electric signal provided by the first power supply terminal 31 and the second power supply terminal 32 acquired by the controller 70 is a first-level electric signal, the controller 70 controls the first input terminal ig1 of the first switch unit 21 to be electrically connected to the first output terminal io1, and controls the second output terminal io2 of the second switch unit 22 to be electrically connected to the second input terminal ig2, so that the isolation transformer 10 isolates the first-level electric signal and transmits it to the robot load 60; when the electric signal provided by the first power supply terminal 31 and the second power supply terminal 32 acquired by the controller 70 is a second-level electric signal, the controller 70 controls the first input terminal ig1 of the first switch unit 21 to be electrically connected to the second output terminal io2, and controls the second output terminal io2 of the second switch unit 22 to be electrically connected to the third input terminal ig3, so that the isolation transformer 10 isolates the second-level electric signal and transmits it to the robot load 60, so that the robot load 60 works normally. In this way, the controller 70 controls the working state of the switch module 20, and then controls the working gear of the isolation transformer 10, so as to improve the control efficiency of the power supply control system of the robot.

[0062] In an optional embodiment, the controller 70 is also electrically connected to multiple robot loads 60 so that the controller 70 controls the electrical connection path between the isolation transformer 10 and each robot load 60 according to the working requirements of each robot load 60, thereby improving the utilization rate of electric energy and saving resources.
