[0081] Working principle:

[0082] First, the shell loading machine 14 automatically discharges the shell of the supercapacitor / battery into the carrier tray, places the positive electrode shell and the negative electrode shell in the corresponding tray, and alternately places the positive electrode shell tray and the negative electrode shell tray on the first conveying device 2. The first conveying device 2 sequentially conveys the tray forward along the glue printing device 4, the film making device 5 and the pressure replenishing device 13. When the tray moves to the position facing the glue printing device 4, the glue printing device 4 picks up the conductive glue in the glue pool 3 and applies the conductive glue on the inner wall of the electrode shell in the tray on the first conveying device 2;

[0083] Then, the tray continues to move forward, and when the tray moves to face the film-making device 5, the film-making device 5 punches the electrode mother material to obtain the electrode, which falls into the electrode shell on the tray under the action of gravity, so that the electrode is bonded to the electrode shell through the conductive glue.

[0084] Then, the material tray continues to move forward. When the material tray moves to the position facing the pressure-compensating device 13, the pressure-compensating device 13 squeezes the pole piece, so that the pole piece and the motor housing are more tightly bonded.

[0085] Secondly, the material tray is manually placed in a vacuum oven 6, which dries the conductive glue and kills bacteria, so that the electrode piece and the electrode shell are quickly bonded and fixed;

[0086] Then, the baked positive electrode shell and negative electrode shell material tray are manually placed into one end of the corresponding second conveying device 8. As the material tray moves forward, the positive electrode liquid injection device 9 injects electrolyte into the positive electrode shell for the first time. The diaphragm assembly device 10 punches the diaphragm mother sheet and drops it into the positive electrode shell in the positive electrode shell material tray on the second conveying device 8 under the action of gravity. The secondary liquid injection device 24 can go back and forth between the two second conveying devices 8 and inject electrolyte into the negative electrode shell and the positive electrode shell for the second time.

[0087] Afterwards, when the negative electrode shell material tray moves to the position about to reach the notch 47, the X-axis cylinder 30 drives the slide seat 31 and the U-shaped frame 20 and other parts to move to the top of the notch 47, and the Z-axis cylinder 32 drives the U-shaped frame 20 to move downward. When the receiving groove 25 moves to be flush with the negative electrode shell material tray, the Z-axis cylinder 32 stops moving, and the feeding cylinder 45 pushes the negative electrode shell material tray forward through the push plate 46 to make the negative electrode shell material tray enter the receiving groove 25. When the negative electrode shell material tray completely enters the receiving groove 25, the feeding cylinder 45 stops pushing. At this time, the pick-up and release cylinder 34 extends to make the connecting plate 49 and the cylindrical magnet 35 move upward, and the cylindrical magnet 35 passes through the through hole to contact the negative electrode shell in the negative electrode shell material tray, and adsorbs and fixes the negative electrode shell in the negative electrode shell material tray;

[0088] Then, the Z-axis cylinder 32 drives the U-shaped frame 20 to move upward, and the X-axis cylinder 30 drives the U-shaped frame 20 to move to the top of the second conveying device 8 for conveying the positive electrode shell material tray, and the motor 36 drives the active bevel gear 37 to rotate, and the active bevel gear 37 drives the driven bevel gear 39, the rotating shaft 38 and the mounting frame 22 to rotate together, so that the negative electrode shell material tray turns 180 degrees, and then the Z-axis cylinder 32 drives the U-shaped frame 20 to move downward, so that the negative electrode shell material tray contacts the positive electrode shell material tray;

[0089] Next, the ejection cylinder 41 drives the ejector plate 42 and the ejector pin 43 to move upwards together, and the ejector pin 43 is inserted into the positive electrode shell material tray to act on the bottom of the positive electrode shell and press the positive electrode shell into the negative electrode shell, and the cylindrical magnet 35 sucks the positive electrode shell and the negative electrode shell together;

[0090] Subsequently, the negative electrode shell tray is put back on the second conveying device 8 for conveying the negative electrode shell tray through the cooperation of the X-axis cylinder 30, the Z-axis cylinder 32, the motor 36 and the pick-up and release cylinder 34, and the battery to be punched is moved to the pressure replenishing device 13 through the conveying of the second conveying device 8, and the positive electrode shell and the negative electrode shell are preliminarily pressurized at the pressure replenishing device 13;

[0091] Afterwards, the batteries to be pressed are placed in the sealing box 15 and are divided by the dividing plate 16 so that the batteries to be pressed are evenly moved to the third conveying device 18.

[0092] Finally, the positive electrode shell and the negative electrode shell to be further pressed together are pressed together by the sealing device 17 to form a battery.
