[0002] As the fundamental unit for the power source of electric vehicles, the performance of the battery cell often determines the overall performance of the electric vehicle. To achieve the required capacity and power of an electric vehicle, multiple individual battery cells need to be combined to form a module. However, inconsistencies in the electrical performance of individual battery cells during module formation can lead to consequences such as reduced module capacity and shortened lifespan. In addition, inconsistencies in dimensional parameters during module assembly will affect subsequent processes such as coating the battery cell surface, ultimately resulting in the module's performance not reaching its optimal level. Therefore, when forming a module from individual battery cells, both the electrical performance parameters and dimensional parameters of the module must be comprehensively considered.

[0025] like Figure 1-4 As shown, this utility model discloses a new energy battery cell sorting device, comprising a detection area 1, a grouping area 2, and a grouping area 3. The detection area 1 includes a first conveyor belt 4, with a detection mechanism 5 on one side of the first conveyor belt 4. A fourth conveyor belt 6 is located at the head of the first conveyor belt 4, adjacent to the detection mechanism 5. A first robotic arm 7 is located on the other side of the first conveyor belt 4. Three equally spaced electric push rods 8 are located on the same side of the first conveyor belt 4 and the detection mechanism 5. The grouping area 2 includes a second conveyor belt 9, comprising three sets of second conveyor belts 9, with each set corresponding to one of the three electric push rods 8. The grouping area 3 includes a third conveyor belt 10, located at the tail end of the three second conveyor belts 9, with a second robotic arm 7 located at the head of the third conveyor belt 10. The robotic arm 11 and the detection mechanism 5 include a support platform 12. A clamping module 13 for fixing the battery cell is provided in the middle of the upper surface of the support platform 12. The clamping module 13 includes a support plate 18. A baffle 19 is provided in the middle of the rear upper surface of the support plate 18. A left guide plate 20 is provided on the left upper surface of the support plate 18. A fixing plate 21 is provided on the right upper surface of the support plate 18. The side wall of the fixing plate 21 is connected to a right guide plate 22 corresponding to the left guide plate 20 by multiple first springs 23. There is a gap between the bottom of the right guide plate 22 and the upper surface of the support plate 18. The support plate 18, the left guide plate 20, and the baffle 19 form a three-base-plane positioning device, which restricts the six degrees of freedom of the battery cell. The right guide plate 22 uses the first springs 23 to press and fix the battery cell.

[0026] A cylinder 14 is installed on the upper surface of the support platform 12, located on one side of the clamping module 13. An electrical testing contact 15 is mounted on the piston rod end of the cylinder 14 via a mounting plate. The electrical testing contact 15 includes a connector 24, one end of which has a threaded head 25, and the other end is connected to an electrode contact 27 via a second spring 26. The electrical testing contact 15 ensures the accuracy of the acquired parameters and prevents the electrode contact 27 from making hard contact with the battery cell electrode, thus avoiding damage to the battery cell electrode. The electrical testing contact 15 enables online acquisition of the battery cell's electrical parameters. The acquired electrical parameter values ​​are transmitted to a PC via a data transmission line for processing and storage, and the information is fed back to the control module in real time for battery cell qualification judgment and sorting. A U-shaped frame 16 is installed on the right side of the upper surface of the support platform 12. Distance sensors 17 are installed in the middle of the horizontal section and near the bottom of the two vertical sections of the U-shaped frame 16. The ranging sensor 17 is a laser ranging sensor. When the ranging sensor 17 is working, the PC sends a signal, and the PLC controls the ranging sensor 17 to collect the external dimensions of the battery cell. The frequency of data collection by the ranging sensor 17 is consistent with the device that transports the battery cell to ensure the accuracy and real-time performance of the data points. The collected data is transmitted to the PC, where it is fitted to calculate the width, thickness, and surface flatness value of the battery cell.

[0027] The first conveyor belt 4 and the fourth conveyor belt 6 are perpendicularly distributed. The second conveyor belt 9 is perpendicular to both the first conveyor belt 4 and the third conveyor belt 10, and the third conveyor belt 10 is parallel to the first conveyor belt 4. First, the battery cell moves on the first conveyor belt 4. The first robotic arm 7 moves it to the detection mechanism to detect the width, thickness, surface flatness, voltage, and internal resistance parameters of the battery cell. If any parameter of the battery cell does not meet the specified single parameter limit, the battery cell is judged to be unqualified, and the first robotic arm 7 moves it to the fourth conveyor belt 6. Qualified battery cells are moved by the first robotic arm 7 to the first... On conveyor belt 4, the cells are pushed onto the second conveyor belt 9 by electric push rods 8 according to the sorting algorithm based on electrical performance parameters. The number of gear zones on the three sets of second conveyor belts 9 is calculated according to the cell classification algorithm. The cell classification algorithm is a conventional algorithm disclosed in the prior art for cell classification calculation. Each gear zone serves as a buffer zone for the inventory of cells of the same gear. When grouping, cells of the same category are selected. When the number of cells in any gear on the second conveyor belt 9 reaches the set grouping scale, grouping begins. The selected cells are transported to the grouping area of ​​the third conveyor belt 10 by the second robotic arm 11 for grouping.

[0028] It is understood that this utility model has been described through some embodiments, and those skilled in the art will recognize that various changes or equivalent substitutions can be made to these features and embodiments without departing from the spirit and scope of this utility model. Furthermore, under the teachings of this utility model, these features and embodiments can be modified to adapt to specific situations and materials without departing from the spirit and scope of this utility model. Therefore, this utility model is not limited to the specific embodiments disclosed herein, and all embodiments falling within the scope of the claims of this application are within the protection scope of this utility model.
