[0019] 4. Through the design of the reduction motor, transmission belt, battery, plug interface, battery power detection module, laser distance sensor and inner concave ring, the second terminal is pushed and inserted into the plug interface of the battery. After the current battery is fully charged, it can be detected by the battery power detection module and send a signal to the controller, and the controller can control the third electric push rod and the reduction motor in sequence, and the third electric push rod can pull the second terminal at one end of the piston rod to disconnect from the plug interface of the current battery and pull it out of the connection box into the guide cylinder, and then the reduction motor will drive the transmission column to drive the transmission belt for transmission, so that the transmission belt can drive the currently fully charged battery to be flush with the first terminal of the second electric push rod, and the other group of uncharged batteries will be driven to be flush with the second terminal of the third electric push rod, and the transmission belt will drive the laser distance sensor at the lower end of the battery to move in the process of driving the battery to rotate, until the uncharged battery is driven down When the laser ranging sensor on the other side is flush with the concave ring, the distance of the emitted laser will increase, which will cause the laser ranging sensor to send a signal to the controller, and the controller can control the reduction motor to stop transmission, ensuring that the battery plug interface can be accurately flush with the first and second connectors, wherein the battery power detection module can detect that the battery is fully charged and send a signal to the controller, thereby triggering a subsequent series of precise operations, which ensures that each battery can be accurately charged to a fully charged state, avoiding overcharging or undercharging, and using the laser ranging sensor to determine the position of the battery. When the laser ranging sensor under the uncharged battery is flush with the concave ring, the controller can control the reduction motor to stop transmission, thereby ensuring that the battery plug interface can be accurately flush with the first and second connectors.
