[0053] As shown in Figure 3 The moving trolley 3 is provided with a grabbing assembly, a central control assembly and a positioning assembly.

[0054] As shown in Figure 2As shown, the central control assembly includes a signal transmitter and a PCL (programmable logic controller), the signal transmitter is mainly used for signal transmission between the battery formation terminal central machine and the PLC, the battery formation terminal central machine is the total control of the battery formation system, the central control assembly in this example is controlled by the battery formation terminal central machine, the signal input end of the signal transmitter is signal connected with the signal output end of the battery formation terminal central machine, the battery formation terminal central machine is a controller that controls the total program of battery formation, so that the signal transmitter receives the signal of the terminal central machine and transmits the information to the PCL, the signal transmitted by the terminal central machine enters the PLC, and the PLC calculates and judges, the signal output end of the PLC is electric signal with the signal input end of the control system, so the PLC will transmit the control signal to the control system, the control system includes a first controller and a second controller, the signal output end of the first controller is signal connected with the signal input end of the grabbing assembly, and the signal output end of the second controller is signal connected with the signal input end of the moving trolley, so the first controller and the second controller are respectively used for controlling the actions of the grabbing assembly and the moving trolley 3.

[0055] As shown in Figure 4 The lower end of the moving trolley 3 is provided with a pulley 31, the pulley 31 is connected with a servo drive motor through a synchronous belt, the servo drive motor is arranged in the moving trolley 3, the signal input end of the servo drive motor is signal connected with the signal output end of the second controller, and the moving trolley 3 driving piece drives the pulley 31 to move after receiving the signal of the second controller, so as to drive the trolley to move in the transportation track 2.

[0056] The battery formation terminal central machine will transmit the position information of the demand cabinet 11 which needs to be fed or discharged to the central control assembly, then the PLC in the central control assembly will convert the signal calculation and transmit it to the second controller, the second controller further controls the trolley to advance or retreat on the transportation track 2 until reaching the specified demand cabinet 11, whether reaching the specified demand cabinet 11 needs the positioning assembly to receive the signal emitted by the signal emitter 12 on the specified demand cabinet 11, since the signals emitted by each demand cabinet 11 are different, so when the positioning assembly receives the corresponding signal, it means that the specified demand cabinet 11 is reached, otherwise the positioning assembly does not receive the emitted signal, which will be fed back to the signal receiver, then the trolley is controlled to advance or retreat again until reaching the specified demand cabinet 11, then the PLC releases the signal to the first controller again, the first controller controls the action of the grabbing assembly, and after completion, the trolley moves to the feeding area or the discharging area.

[0057] The grabbing assembly is arranged on the upper end face of the moving trolley 3, and the grabbing assembly includes a turntable 4, a mechanical arm and a clamping piece arranged at the end of the mechanical arm. The upper end face of the moving trolley 3 is also provided with a placement area 40, and a plurality of battery packs are arranged in the placement area 40, and each battery pack includes a plurality of batteries 401.

[0058] Turntable 4 is placed on bracket 42, which is fixedly connected to the mobile trolley 3. A fourth servo motor 41 is installed on the upper end of turntable 4. The fourth servo motor 41 is connected to turntable 4 and drives turntable 4 to rotate. A first rocker arm 52 is installed around turntable 4. The fourth servo motor 41 drives turntable 4 and the first rocker arm 52 to rotate. At the same time, the fourth servo motor 41 is also connected to an RV reducer. The output end of the RV reducer is connected to turntable 4 through transmission component 30.

[0059] like Figure 6 and Figure 10 As shown, the first rocker arm 52 includes a horizontal plate and a vertical plate connected to the horizontal plate. The horizontal plate is also provided with reinforcing ribs 521 to enhance load-bearing capacity. The horizontal plate is connected to the turntable 4. The vertical plate has a through hole and is equipped with a first servo motor 51 and an RV reducer. The first servo motor 51 and the RV reducer are connected. The robotic arm includes a first rocker arm 5, a second rocker arm 6, and a third rocker arm 7 connected in sequence. The first rocker arm 5 has discs at both ends, with grooves inside the discs. The output end of the RV reducer extends out of the through hole and connects to the first rocker arm 5. When the first servo motor 51 is activated, it can drive the first rocker arm 5 to rotate.

[0060] like Figure 9 As shown, the other end of the first rocker arm 5 is connected to a second rocker arm frame 62 and a second servo motor 61. The second servo motor 61 is connected to the second rocker arm frame 62. The second rocker arm frame 62 and the first rocker arm frame 52 have the same structure. The second rocker arm 62 is used to connect the first rocker arm 5 and the second rocker arm 6. The output shaft of the second servo motor 61 is connected to the input end of the RV reducer. The output end of the RV reducer extends through a through hole on the vertical plate of the second rocker arm 62 and is connected to a bearing 63. The outer ring of the bearing 63 is connected to and linked with the RV reducer. The inner ring of the bearing 63 extends to connect and link with the disc of the first rocker arm 5. The outer ring of the output end of the RV reducer is equipped with a gear, and the output end with the gear meshes with the bore of the inner ring of the bearing. Thus, when the second servo motor 61 is driven, the output end of the RV reducer moves, which drives the inner ring of the bearing to rotate. Since the inner ring of the bearing is connected to the first rocker arm 5, the first rocker arm 5 is equivalent to a fixed part during this movement. When the inner ring of the bearing does not rotate, the output end of the RV reducer will rotate around the bearing ring. At the same time, the RV reducer, the second servo motor 61, the outer ring connected to the RV reducer, and the second rocker arm 62 rotate simultaneously, thus realizing the drive of the second rocker arm 62 by the second servo motor 61.

[0061] The RV reducer includes an input end and an output end. The input end is connected to the servo motor shaft, and the output end is connected to the rocker arm. The presence of the RV reducer makes the servo motor drive smoother, which in turn makes the subsequent rotation of the rocker arm smoother.

[0062] like Figure 8 and 11 As shown, a fifth servo motor 8 is also provided on the cross plate of the second rocker arm 62. The fifth servo motor 8 is connected to the second rocker arm 62, and the shaft of the fifth servo motor 8 is connected to one end of the second rocker arm 6 through the second transmission component 302 to achieve linkage. The signal receiving end of the fifth servo motor 8 is electrically connected to the signal output end of the first controller, so that when the fifth servo motor 8 is activated, it can drive the second rocker arm 6 to rotate. In this example, the second transmission component 302 is preferably a transmission belt, which transmits the motion between the fifth servo motor 8 and the second rocker arm 6.

[0063] like Figure 7 As shown, the third rocker arm 7 includes an outer shell 72 and an inner sleeve rod 73, with the outer shell 72 fitted over the inner sleeve rod 73.

[0064] like Figure 5 As shown, the other end of the second rocker arm 6 is connected to a U-shaped component 10. The U-shaped component 10 has a U-shaped hole 101. A first transmission component 300 is provided on one side of the U-shaped component. The shaft of one end of the first transmission component 300 extends to the U-shaped hole, and the other end is connected to the third servo motor. A rotating sleeve is provided outside the outer shell 72 of the third rocker arm. The rotating sleeve matches the shaft of the transmission component. In this way, the third servo motor 71 can drive the third rocker arm to rotate through the first transmission component 300.

[0065] A sixth servo motor 9 is mounted on the third rocker arm 7 and is connected to the outer casing 72. The shaft of the sixth servo motor 9 is connected to and linked with one end of the inner sleeve rod 73, allowing the sixth servo motor 9 to drive the inner sleeve rod 73 to rotate. As the inner sleeve rod 73 rotates, it can grip the battery from different angles, accommodating battery stacks with various arrangement shapes. The signal receiving end of the sixth servo motor is electrically connected to the signal output end of the first controller.

[0066] One end of the inner sleeve rod 73 is connected to multiple clamping components via a plate, such as... Figure 12 As shown, the clamping component includes at least two automatically opening and closing grippers. In this example, the clamping component is preferably a finger cylinder 20, and has multiple finger cylinders. Each finger cylinder 20 includes two grippers 201, which automatically open and close under the control of the finger cylinder 20. A gripping plate 202 is provided on one side of each gripper 201. The gripping plate 202 grips the battery as the gripper 201 moves. The multiple finger cylinders 20 are controlled by a hydraulic control component, the input end of which is also connected to the output end of a first controller and controlled by the first controller. In this example, the gripping plate includes a connecting plate and an extension plate. The extension plate is located at both ends of the connecting plate, and the connecting plate is connected to the grippers. The extension plate is used to grip the battery, and the extension of the extension plate can make the battery more evenly stressed and better gripped.

[0067] The first controller 34 transmits the signal to the first servo motor 51, the second servo motor 61, the third servo motor 71, the fourth servo motor 41, the fifth servo motor 8 and the sixth servo motor 9 after receiving the signal released by the PLC again, and then the first servo motor 51, the second servo motor 61, the third servo motor 71, the fourth servo motor 41, the fifth servo motor 8 and the sixth servo motor 9 drive the components of the mechanical arm to grasp, feed and discharge according to the received information.

[0068] In specific use, the second controller 35 controls the trolley to run on the transportation track 2 after receiving the information of the terminal central machine at the signal input end of the central control assembly, and the trolley stops after running to the specified demand cabinet 11. When the trolley runs, the signal emitter 12 of the specified demand cabinet 11 emits a signal, and if the positioning assembly receives the signal emitted by the specified demand cabinet 11, the signal will not be transmitted to the central control assembly, and the first controller will emit a signal to control the grabbing assembly to grasp the battery and move it out of or into the specified demand cabinet 11. If the positioning assembly does not receive the signal emitted by the specified demand cabinet 11, the positioning assembly will transmit the information to the central control assembly, and the central control assembly will transmit the information again to control the trolley 3 to advance again through the second controller 35. The distance of the advance will be determined in advance, and the trolley 3 will stop advancing until the positioning assembly no longer feeds back the signal emitted by the specified demand cabinet 11, and then the first controller 34 controls the grabbing assembly to act and grasp.

[0069] The above embodiments are only for illustrating the technical concept and characteristics of the present application, and the purpose is to enable those skilled in the art to understand the content of the present application and implement it, and cannot limit the protection scope of the present application.
