The upper side of the device body 1 is fixedly connected with a mounting seat 2, the inner side of the mounting seat 2 is rotatably connected with a pushing device 3, and the pushing device 3 protrudes from the upper surface of the mounting seat 2. The transfer box 5 is located in the space below the end of the pushing device 3. The inside of the transfer box 5 is fixedly connected with a pressure sensor 6, the outside of the transfer box 4 is fixedly connected with a fixing plate 7, one side of the fixing plate 7 is fixedly connected with a driving motor 8, and the driving motor 8 and the pressure sensor 6 are connected by a signal. A rotating rod 9 is fixedly connected to one side of the driving motor 8, a winding post 10 is fixedly connected to the outside of the rotating rod 9, a pull rope 11 is wound on the outside of the winding post 10, and the end of the pull rope 11 passes through the upper surface of the transfer box 4 and is fixedly connected to the transfer box 5, a sensor sheet 13 is installed inside the transfer box 4, a laser emitter 12 is fixedly connected to the outside of the transfer box 5, the laser emitter 12 and the sensor sheet 13 are connected by signal, and the sensor sheet 13 and the pushing device 3 are also connected by signal, and the laser emitter 12 and the sensor sheet 13 are located in the same vertical plane.

[0026] The number of the mounting seats 2 is two and they are arranged symmetrically. The outer surface of the pushing device 3 is provided with protrusions for pushing.

[0027] The rotating rod 9 and the fixed plate 7 are rotatably connected, and the fixed plate 7 can provide supporting force for the rotating rod.

[0028] An exit 14 is provided at the rear side of the transfer box 4 , and the robot arm can grab and transfer the battery pack delivered to the opening 14 through the opening 14 .

[0029] A mounting plate 15 is fixedly connected between the two groups of mounting seats 2, and a through hole 16 is opened on the upper side of the mounting plate 15. A rotating shaft 17 is rotatably connected inside the device body 1, and a push plate 18 is fixedly connected to the outside of the rotating shaft 17, and the end of the push plate 18 can extend out of the through hole 16. A control box 19 is fixedly connected to the outside of the device body 1, and a driving mechanism is installed inside the control box 19 to provide power for the pushing device 3 and the rotating shaft 17.

[0030] The working principle of a battery core welding device based on the embodiment is that after the worker completes the welding of the battery pack, the pressure sensor 6 is used to monitor whether there is a battery pack in the transfer box 5, thereby controlling the operation of the drive motor 8, so that the winding column 10 releases or reels the wire, and the pull rope 11 is extended or recovered to control the rise and fall of the transfer box 5, and whether the sensor sheet 13 receives the laser signal emitted by the laser transmitter 12, thereby controlling the operation of the push device 3 to cooperate, so that when the transfer box 5 is in the initial position, the sensor sheet 13 can receive the laser signal, so that the push device 3 pushes the battery pack to be transferred into the transfer box 5, and the pressure can be sensed by the pressure sensor 6 to trigger the operation of the drive motor 8, and the transfer box 5 is controlled to descend, resulting in The laser emitter 12 follows the decline, so that the sensor sheet 13 cannot receive the signal. At this time, the pushing device 3 stops running, and then the robot takes out the battery pack through the outlet 14. At this time, the pressure sensor 6 cannot sense the pressure, and the drive motor 8 can be reversed to make the transfer box 5 rise. When the transfer box 5 is reset to the initial position, the sensor sheet 13 can receive the laser signal emitted by the laser emitter 12 again, and the pushing device 3 is operated again to transport the battery pack. Repeating the cycle can enhance the accuracy of the transfer and discharge, and the transfer of the battery pack is completed. The transfer box 5 containing the battery pack is reset to the initial position before the next battery pack is transported and discharged, which greatly avoids the situation where the battery pack is damaged by falling from a height.
