[0018] The present invention will be further explained below in conjunction with the accompanying drawings and related knowledge, and described clearly and completely. Obviously, the described application is only a part of the embodiments of the present invention, rather than all the embodiments.

[0019] The existing robot charging and energy replenishment technology has the following disadvantages: Charging at a fixed point in a dedicated facility: In the prior art, robots need to be charged at a fixed point in a dedicated facility, which results in the charging path not overlapping with the normal working path, adding extra workload.

[0020] Long charging time at fixed points: The robot is charged at a fixed point, and a single charge takes a long time, reducing work efficiency.

[0021] The charging facility has a large structure: The existing charging facilities have a large structure, occupy a lot of space, and are inconvenient to use.

[0022] The present invention provides an automatic energy replenishment device for a rail-type robot for orderly charging of new energy electric vehicles, which can solve the problems existing in the prior art. Figure 1As shown in the structure, it includes a control system, a communication interface, an I / O interface, a battery pack BMS system, a code scanning system, a drive system, a photoelectric switch and a walking mechanism; the control system exchanges information with the battery pack BMS system and the code scanning system through the communication interface for power detection and confirmation of the charging position, and also senses the operating status of the robot through the I / O interface and the photoelectric switch; the control system drives the robot to move on the walking mechanism by controlling the drive system according to the information of the robot's power detection and perception to achieve accurate automatic energy replenishment.

[0023] The control system in the present invention is the core of the entire charging robot and is responsible for coordinating and controlling all operations and functions of the robot. The communication interface is used for data exchange between the robot controller and the code scanning system.

[0024] I / O interface: provides input and output functions, allowing the robot controller to interact with external devices. Battery pack: provides power to the robot and is its energy source.

[0025] Scanning code system: used to identify the QR code corresponding to each charging parking space to ensure the correctness of the charging target and the robot's walking position.

[0026] It should be noted that the present invention first checks whether the current power of the robot is lower than the set value through the BMS system. If it is lower than the set value, the photoelectric switch (sensor) is used for state perception during the robot's walking process to help the robot slow down at the right time and stop accurately at the target position (charging position). The QR code corresponding to each charging parking space is then identified through the code scanning system to ensure the correctness of the charging target and the robot's walking position, thereby completing the energy replenishment.

[0027] In the present invention, the driving system enables the robot to move to a specified position. Sensor: used for state perception during the robot's walking process, helping the robot to slow down at the right time and stop accurately at the target position. BMS system (battery management system): monitors and manages the status of the battery pack to ensure safe and efficient operation of the battery. Walking mechanism: enables the robot to move on the track. Telescopic mechanism: used for the robot to drive the charging probe to extend to the charging interface position. Charging contact pin: connected to the charging interface for power transmission.

[0028] The present invention realizes the detection of the energy of the charging robot and the high-frequency recognition of the current position through the combination of photoelectric switches, BMS systems, and code scanning system recognition technologies, and adjusts the running direction and speed of the robot according to the recognition results until the target charging position is reached. The target charging position is then confirmed by the code scanning system, which solves the energy replenishment problem of the rail-type charging robot during long-term operation, improves its operating efficiency and reliability, reduces manual intervention, and reduces maintenance costs.

[0029] Reference Figure 2 As shown, the present invention provides an automatic energy replenishment method for a new energy electric vehicle orderly charging rail-type robot based on an automatic energy replenishment device for a new energy electric vehicle orderly charging rail-type robot, which specifically includes the following steps: Step S1: Start the energy replenishment process. The robot first performs a system self-check to ensure that all components and systems function normally. Step S2: Check whether the current power of the robot is lower than the set value. If the power is higher than the set value, the robot will continue to perform the current task or return to the idle state; if the power is lower than the set value, the robot will move to the energy replenishment position; Step S3: using the photoelectric switch to determine the current position of the robot, determine whether the robot is running forward or reverse on the walking mechanism, and adjust the robot's motion state according to the sensed situation; Step S4: After reaching the charging position, the robot identifies and confirms the charging position through the code scanning system, connects to the charging pile through the charging contact pin, and starts the charging process; if the position recognition is wrong, the robot will readjust the position. After confirming that the position is correct, the robot extends the charging contact pin to prepare to connect to the charging pile. The charging contact pin is connected to the charging pile and the charging process begins. During the charging process, the robot continuously monitors the charging status and power changes; if the power does not reach the set value, the robot continues to charge. If the power reaches the set value and there is a task, the robot will stop charging and perform the task. Check whether the robot is fully charged. If it is fully charged, the automatic charging ends. If it is not fully charged, continue charging. When the power reaches the set value and there is a task required, the robot ends the charging process and prepares to perform the task.

[0030] The present invention integrates the controller, BMS system, code scanning system, drive system, and photoelectric switch to realize power monitoring, logic judgment, drive control, code scanning recognition, and stylus charging. Moreover, the charging path of the robot coincides with the normal working path. The robot completes charging during the normal walking and positioning process, realizing instant energy replenishment. Fully automatic charging and energy replenishment, without the need for human intervention, the robot can autonomously replenish energy according to actual needs in an unattended situation, greatly improving the convenience of charging and the operating efficiency of the robot. The charging structure designed by the present invention is combined with the robot walking and positioning mechanism, with a compact structure, reduced space occupancy, and improved convenience of use.

The protection scope of the present invention is not limited to the above embodiments, and all technical solutions under the idea of ​​the present invention belong to the protection scope of the present invention.
