[0024] As Figure 1 shown, a battery cell conveying line 1 is provided on a workbench 10. Above one side of the battery cell conveying line 1, a battery cell grasping mechanism 2 is provided. Behind the battery cell grasping mechanism 2, a battery cell rotating mechanism 3 is provided. Behind the battery cell rotating mechanism 3, a battery cell conveying device 4 is provided. Behind the battery cell conveying device 4, a battery cell extracting mechanism 5 is provided. On one side of the battery cell conveying device 4, a distance separating mechanism 6 is provided. Above the distance separating mechanism 6, a battery cell manipulator 11 is provided. On one side of the distance separating mechanism 6, a positive electrode polarity reversing mechanism 7 and a negative electrode polarity reversing mechanism 8 are respectively provided.

[0025] As Figure 2 shown, a support frame 1-1 is provided outside the battery cell conveying line 1, and a plurality of battery cell temporary storage boxes 1-2 are provided inside the support frame 1-1. During specific use, the battery cell temporary storage boxes 1-2 are used to temporarily store battery cells or empty battery boxes.

[0026] As Figures 2 to 3As shown in the figure, the battery cell grasping mechanism 2 includes a first bracket 2-1, a second bracket 2-2, a grasping moving plate 2-3, a first grasping cylinder 2-4, and a second grasping cylinder. The first bracket 2-1 and the second bracket 2-2 are respectively arranged on the left and right sides of the battery cell conveying line 1. A linear guide rail 2-6 is provided at the upper end of the first bracket 2-1. One end of the grasping moving plate 2-3 is connected to the linear guide rail 2-6 through a connecting block. The other end of the grasping moving plate 2-3 is connected to a conveying device 2-7. The conveying device 2-7 is fixed at the upper end of the second bracket 2-2. A first grasping cylinder 2-4 is connected to the middle of the grasping moving plate 2-3. The output shaft of the first grasping cylinder 2-4 is connected to a grasping frame 2-8. The lower end of the grasping frame 2-8 is connected to a grasping plate 2-10 through a second grasping cylinder 2-9. A number of magnets 2-11 are fixed in the grasping plate 2-10 by bolts. When the battery cell grasping mechanism 2 is specifically used, the conveying device 2-7 drives one end of the grasping moving plate 2-3 to move, and the other end of the grasping moving plate 2-3 moves along the linear guide rail 2-6 through the connecting block. When it is necessary to grasp the battery cell, the first grasping cylinder 2-4 drives the grasping frame 2-8 to move up and down, and the second grasping cylinder 2-9 drives the grasping plate 2-10 to move up and down, thereby driving the magnets 2-11 to move up and down, so as to adsorb the battery cell.

[0027] As Figures 4 to 5 shown in the figure, the battery cell rotating mechanism 3 includes a rotating motor 3-1 and a battery cell placement box 3-2. A rotating motor 3-1 is provided on one side of the rear of the battery cell grasping mechanism 2. The output end of the rotating motor 3-1 is connected to a cross-shaped connecting battery cell placement box 3-2. A number of battery cell placement cavities that match the structure of the battery cell 9 are provided on each side of the battery cell placement box 3-2. When it is specifically used, the battery cell grasping mechanism 2 transfers the battery cell to the battery cell placement box 3-2, and then the rotating motor 3-1 drives it to rotate 90 degrees, so as to rotate the battery cell transfer box 3-2 loaded with the battery cell to one side of the battery cell conveying device 4 for subsequent processes.

[0028] The battery cell conveying device 4 includes a battery cell conveyor belt 4-1, a slope, and a baffle. A battery cell conveyor belt 4-1 is provided at the rear of the battery cell rotating mechanism 3. The end of the battery cell conveyor belt 4-1 is connected to a downward-sloping slope 4-2. A U-shaped groove is provided at the end of the slope. The battery cell extraction mechanism 5 includes a horizontally arranged first telescopic cylinder 5-1, a support plate 5-2, and a support column 5-3. A support plate 5-2 is provided on one side of the rear of the battery cell conveying device 4. The lower end of the support plate 5-2 is connected to the workbench 10 through the support column 5-3. The upper end of the support plate 5-2 fixes the first telescopic cylinder 5-1 through a fixing block 5-4. The output shaft of the telescopic cylinder is connected to an extraction plate 5-5. A number of magnets 5-6 are provided in the extraction plate 5-5. When it is specifically used, the battery cell extraction mechanism 5 extracts the battery cell to the battery cell conveyor belt 4-1 through the magnets 5-6. Under the action of the battery cell conveyor belt 4-1, the battery cell enters the inclined slope and thus enters the spacing mechanism.

[0029] Baffles 4-3 are provided on both sides of the battery cell conveyor belt 4-1 and the slope 4-2 to prevent the battery cells from falling.

[0030] As Figure 4 , Figure 6 shown, the distance separation mechanism 6 includes a telescopic cylinder two 6-1, a distance separation seat 6-3, and a fixed-distance bolt 6-5. There is a mounting seat 6-2 at the rear of the battery cell conveying device 4. The lower end of the mounting seat 6-2 is connected to a lifting cylinder 6-6. The upper end of the mounting seat 6-2 is provided with symmetrically arranged front and rear guide seats 6-4. A chute is formed between the guide seats 6-4. A number of evenly distributed distance separation seats 6-3 are provided in the chute. Adjacent distance separation seats 6-3 are connected by fixed-distance screws 6-5. The upper end of the distance separation seat 6-3 is provided with a distance separation groove 6-5. The lower end of the distance separation seat 6-3 at the end extends into the mounting seat 6-2 and is connected to the telescopic cylinder two 6-1. When the distance separation mechanism 6 is in use, before the battery cells roll down, the telescopic cylinder two 6-1 remains closed so that the battery cells can roll into the corresponding side distance separation grooves. After the distance separation grooves are filled, the telescopic cylinder two 6-1 opens to separate the adjacent distance separation seats. During the separation process, it is pulled by the fixed-distance bolt 6-5 to complete fixed-distance equal division.

[0031] The mounting seat 6-2 is located in the U-shaped groove at the end of the slope 4-2.

[0032] As Figure 7 shown, the positive polarity inversion mechanism 7 includes a slide rail 7-5 and a finger cylinder 7-1. The slide rail 7-5 is fixed to the upper end of the workbench 10. A slider is embedded in the upper end of the slide rail 7-5. Finger cylinders 7-1 are respectively provided on the left and right sides of the slider. The two clamping claws 7-4 of the finger cylinder 7-1 are respectively connected to a semi-closed clamp one 7-2 and a semi-closed clamp two 7-3. Mounting grooves 7-6 that match the battery cells 9 are provided on the semi-closed clamp one 7-2 and the semi-closed clamp two 7-3. The structure of the negative polarity inversion mechanism 8 is the same as that of the positive polarity inversion mechanism 7. As Figures 8 to 9 shown, during specific use, the battery cell manipulator 11 grabs the battery cells with the distance separation completed to the positive polarity inversion mechanism 7 or the negative polarity inversion mechanism 8. For the positive polarity inversion mechanism 7, the battery cell manipulator 11 grabs the battery cells into the semi-closed clamp one 7-2 located at the front side. For the negative polarity inversion mechanism 8, the battery cell manipulator 11 grabs the battery cells into the semi-closed clamp two 7-3 located at the rear side. Then the finger cylinder 7-1 closes to clamp the battery cells and complete the inversion of the polarity. At this time, among the positive polarity inversion mechanism 7 and the negative polarity inversion mechanism 8, the polarities of the battery cells located above are different, which is convenient for distinction.

[0033] When the utility model is in use, the battery cell 9 is input from the input port of the battery cell conveying line 1. The battery cell conveying line 1 conveys the battery cell 9 to the lower part of the battery cell grasping mechanism 2. The battery cell grasping mechanism 2 sucks the battery cell and transfers the battery cell to the battery cell placement box 3-2 of the battery cell rotating mechanism 3. Then, the battery cell rotating mechanism 3 rotates 90 degrees. The battery cell extraction mechanism 5 extracts the battery cell and releases the battery cell on the battery cell conveyor belt 4-1 of the battery cell conveying device 4. The battery cell enters the slope 4-2 under the action of the battery cell conveyor belt 4-1. The battery cell rolls down along the slope 4-2 to the spacing mechanism 6. Then, the spacing mechanism separates the battery cells. Under the action of the battery cell manipulator 11, the battery cells are transferred to the positive polarity inversion mechanism 7 or the negative polarity inversion mechanism 8 to complete the polarity inversion of the battery cells.
