[0026] In order to make the above-mentioned purposes, features and advantages of the present application more obvious and easy to understand, the present application is further described in detail below in conjunction with the accompanying drawings and specific implementation methods. Obviously, the described embodiments are part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of this application.

[0027] The present application provides a robot encoder management system, which is electrically connected to a main power supply and a robot, respectively, and the robot includes an encoder and a battery box; the main power supply is also electrically connected to a robot control cabinet, and the robot control cabinet is used to power the encoder after startup; the robot encoder management system is used to power the encoder when the robot control cabinet is powered off and the main power supply is not powered off; the battery box is used to power the encoder when the main power supply is powered off.

[0028] In this embodiment, the main power supply provides power for the entire robot encoder power supply system. In this application, a normally-on power supply AC220 / 380V is used to supply power (main power supply) to the main circuit.

[0029] Among them, the relationship between the robot and the robot control cabinet is as follows Figure 1 shown. Figure 1 Schematic diagram of an industrial robot shown in one embodiment of the present application. Figure 1 In the figure, 1 represents the encoder in the robot, 2 represents the signal line between the robot control cabinet and the robot, 3 represents the battery box in the robot, 4 represents the robot control cabinet, and 5 represents the robot.

[0030] In this embodiment, the robot control cabinet includes a six-axis servo amplifier. When the robot control cabinet is not powered off, the encoder is mainly powered by the six-axis servo amplifier in the robot control cabinet. When the robot control cabinet is powered off but the main power supply is not powered off, the encoder is powered by the robot encoder management system designed in this application. When the main power supply is powered off, the encoder is powered by the battery box inside the robot.

[0031] In this embodiment, a robot encoder management system is provided to continue to supply power to the encoder when the robot control cabinet is powered off, which can increase the service life of the battery box of the robot body, reduce the replacement cycle of the battery box, and reduce the workload of maintenance personnel.

[0032] In combination with the above embodiments, in one implementation, the robot encoder management system includes: a DC switching power supply and an electromagnetic intermediate relay; the DC switching power supply is electrically connected to the main power supply and the electromagnetic intermediate relay, respectively, and the electromagnetic intermediate relay is electrically connected to the battery box and the encoder, respectively; the DC switching power supply is used to supply power to the encoder through the electromagnetic intermediate relay when the robot control cabinet is powered off and the main power supply is not powered off; the electromagnetic intermediate relay is used to supply power to the encoder through the current output by the battery box when the main power supply is powered off.

[0033] In this embodiment, if the robot control cabinet is powered off but the main power supply is not, since the main power supply, the DC switching power supply, the electromagnetic intermediate relay and the encoder are connected, the main power supply can continue to supply power to the encoder through the path formed between the DC switching power supply, the electromagnetic intermediate relay and the encoder. If the main power supply is powered off, causing the DC switching power supply to be powered off, a path can be formed between the battery box, the electromagnetic intermediate relay and the encoder, so that the encoder can continue to be powered through the battery box.

[0034] Among them, the electromagnetic intermediate relay can be a current relay.

[0035] In this embodiment, a DC switching power supply and an electromagnetic intermediate relay are provided, so that when the robot is powered off, the encoder can be smoothly powered, thereby increasing the service life of the battery box of the robot body.

[0036] In combination with the above embodiments, in one implementation, the robot encoder management system further includes: a DC voltage detection relay switch and a display light; the DC voltage detection relay switch is electrically connected to the DC switching power supply, the battery box, and the display light, respectively. The DC voltage detection relay is used to detect the power level of the battery box, and when the power level is lower than a preset power level, the display light is controlled to display a warning light.

[0037] In this embodiment, the DC voltage detection relay switch is powered by a DC switching power supply, and can monitor the power level of the battery box in real time. When the power level of the battery box is lower than the preset power level, the display light is controlled to display a warning light. For example, the display light can be controlled to be always on to remind relevant staff that the current power level of the battery box is too low and needs to be replaced in time.

[0038] The display light may be an LED power status display light or other types of display lights. The display light may be set according to actual needs, and this embodiment does not limit this.

[0039] In this embodiment, the DC voltage detection relay switch is powered by the DC switching power supply when the robot control cabinet is powered off and the main power supply is not powered off, and is powered by the battery box when the main power supply is powered off.

[0040] In specific implementation, if the main power supply is not cut off but the robot control cabinet is cut off, the DC voltage detection relay switch is powered by the DC switching power supply, and the DC voltage detection relay switch can monitor the power of the battery box in real time. If the main power supply is cut off, the main power supply cannot supply power to the DC switching power supply. At this time, since a path can be formed between the battery box, the intermediate relay, the switching power supply and the DC voltage detection relay switch, the DC voltage detection relay switch can continue to monitor the power of the battery box.

[0041] In this embodiment, the setting of the robot encoder management system has at least the following effects: First, the robot encoder management system is set in the robot control cabinet and the outside of the robot, which is easy to operate, simple to maintain, and highly efficient. Second, the staff can intuitively judge the voltage and power status of the battery box inside the robot according to the status of the display light without opening the robot control cabinet, which can significantly improve the management efficiency of the robot and reduce maintenance costs. Third, maintenance personnel do not need to open the robot control cabinet regularly, which can increase the service life of the robot control cabinet. Fourth, in the process of powering the encoder through the battery box, the DC voltage detection relay switch can continue to monitor the power of the battery box and display it through the display light, so that the staff can pay attention to the power status of the battery box in time, and replace the battery box when the power is low, which can effectively ensure that the value of the encoder in the robot is not lost and reduce the subsequent maintenance cost of the robot.

[0042] In one embodiment, the DC switching power supply is also used to convert the AC 220 / 380V voltage input by the main power supply into a DC 6V output voltage. The input of the DC voltage detection relay switch is a DC 6V voltage, which is used to detect the battery voltage of the battery box in the robot and output a DC 6V voltage. The input of the electromagnetic intermediate relay is a DC 6V voltage, the output power line of the battery box is connected to the normally closed end of the electromagnetic intermediate relay input, the DC switching power supply is connected to the normally open end of the electromagnetic intermediate relay input, and the output end of the electromagnetic intermediate relay is connected in parallel with the battery box power line and the DC switching power line. The input of the display light is a DC 6V voltage.

[0043] In one embodiment, the robot control cabinet is also used to display the current power of the battery box when the robot control cabinet itself is not powered off.

Figure 2 , the circuit diagram obtained by actual circuit connection is as follows Figure 3 shown. Figure 3 This is a circuit connection diagram of a robot encoder management system shown in one embodiment of the present application. Figure 3 The connection principle between each device in Figure 2 The connection principle between each device is the same.

[0045] exist Figure 3 In the embodiment, the robot encoder management system generally includes module A, module B and module C. Module A corresponds to the voltage detection module (i.e., DC voltage detection relay switch) in the voltage detection feedback alarm unit, and the voltage detection feedback alarm unit also includes an alarm display light located in module B.

[0046] Module B corresponds to the DC switching power supply, electromagnetic intermediate relay, robot body unit and alarm display light. The robot body unit includes a battery box and an encoder. The electromagnetic intermediate relay is a current relay. Figure 3 KA is used to represent the DC switching power supply above the electromagnetic intermediate relay. Figure 3 It is mainly used to convert 220V AC voltage into 6V DC voltage.

[0047] Module C corresponds to the robot control cabinet unit, including the servo amplifier.

[0048] The specific structure inside module A is as follows Figure 4 As shown, the specific structure inside module B is as follows Figure 5 As shown, the specific structure inside module C is as follows Figure 6 shown. Figure 4 yes Figure 3 Schematic diagram of module A in the robot encoder management system. Figure 5yes Figure 3 Schematic diagram of module B in the robot encoder management system. Figure 6 yes Figure 3 Schematic diagram of module C in the robot encoder management system.

[0049] The following will be combined Figure 2-Figure 6 , a detailed description is given of the usage process of a robot encoder management system of the present application.

[0050] When the robot control cabinet is working normally, the encoder in the robot is powered mainly through the servo amplifier in the robot control cabinet. At this time, the DC voltage detection relay switch can monitor the power of the battery box in real time. When the power is within the normal range, the display light goes out, and when the power is within the abnormal range, the display light is always on. When the robot control cabinet is powered off, if the main power supply is not powered off, a path is formed between the main power supply, the DC switching power supply, the electromagnetic intermediate relay and the encoder, so that the encoder can continue to be powered. At this time, the DC voltage detection relay switch can monitor the power of the battery box in real time. If the power is lower than the preset power, the control display light is always on to remind the relevant staff to replace the battery box in time to ensure that the encoder data is not lost. If the main power supply is powered off, a path is formed between the battery box, the electromagnetic intermediate relay and the encoder, so that the encoder can be powered by the battery box. At this time, a path can also be formed between the battery box, the electromagnetic intermediate relay, the DC switching power supply and the DC voltage detection relay switch, so that the DC voltage detection relay switch can monitor the power of the battery box in real time. Therefore, no matter how the encoder is powered, the DC voltage detection relay switch can monitor the power of the battery box.

[0051] The robot encoder management system provided in the present application can not only realize the power supply to the encoder in the robot, but also realize the power monitoring of the battery box in the robot. It is mainly designed by using a combination of a normally-on power supply, a DC switching power supply, a DC voltage detection relay switch, an LED power status indicator light, an electromagnetic intermediate relay and a robot body battery box. It can ensure that the encoder can continue to be powered after the robot control cabinet is powered off, and when the battery box is used to power the encoder, the power of the battery box can be monitored in real time and the display light can be used to promptly remind relevant staff to replace the low-power battery box, thereby ensuring that the robot encoder data is not lost.

[0052] In summary, the robot encoder management system set in this application continues to power the encoder when the robot control cabinet is powered off, which can not only increase the service life of the battery box of the robot body, reduce the replacement cycle of the battery box, and reduce the workload of maintenance personnel, but also monitor the power of the battery box so that the staff can pay attention to the power status of the battery box in time and replace the battery box when the power is low to ensure that the value of the encoder in the robot body is not lost.
