Therefore, the capsule airtightness detection mechanism 60 of this embodiment can detect the airtightness of two liquid injection capsules 502 at the same time, improving the production efficiency. There are two detection lifting cylinders 64, and the two detection lifting cylinders 64 are arranged opposite to each other front and back. Since there are two nozzle groups, there are also two vacuum pipelines and two connecting pipelines. Therefore, the pressure gauge 67 can measure the air pressure inside the two liquid injection capsules 502 at the same time.

[0036] The top end of the third detection plate 63 is provided with detection guide posts 631. The top ends of the detection guide posts 631 pass through the through holes of the second detection plate 62 and are located between the first detection plate 61 and the second detection plate 62. A detection linear bearing 632 is disposed through the through holes of the second detection plate 62, and the detection linear bearing 632 is sleeved on the outer periphery of the detection guide posts 631. The up and down movement of the third detection plate 63 can drive the up and down movement of the detection guide posts 631. The provided detection guide posts 631 play a guiding role in the up and down movement of the third detection plate 63, and the provided detection linear bearing 632 provides support for the up and down movement of the detection guide posts 631. In this embodiment, there are four detection guide posts 631, and the four detection guide posts 631 are respectively arranged at the four right angles at the top end of the third detection plate 63. The number of the detection linear bearings 632 corresponds to the number of the detection guide posts 631. It can be understood that the number of the detection guide posts 631 and the detection linear bearings 632 can be set according to the actual situation.

[0037] Combined with Figures 11 to 14As shown, the liquid injection capsule switching belt 50 runs through the frame 10 and is close to the left end of the frame 10. The liquid injection capsule switching belt 50 extends in the front-rear direction. The liquid injection capsule switching belt 50 is used to convey the liquid injection capsule 502 to the buckle-taking cup manipulator 30, to convey the liquid injection capsule 502 and the battery 501 inside the liquid injection capsule 502 to the capsule airtightness detection mechanism 60 after the battery 501 after the first liquid injection is placed into the liquid injection capsule 502, and to convey the liquid injection capsule 502 and the battery 501 inside the liquid injection capsule 502 to the second capsule switching mechanism 70 after the airtightness of the liquid injection capsule 502 is detected by the capsule airtightness detection mechanism 60. The liquid injection capsule switching belt 50 is located below the buckle-taking cup manipulator 30 and the capsule airtightness detection mechanism 60. The first capsule switching mechanism 40 is arranged in front of the liquid injection capsule switching belt 50. In actual application, the first capsule switching mechanism 40 is close to one end of the liquid injection capsule conveying line and is located on the right side of the liquid injection capsule conveying line. The first capsule switching mechanism 40 is used to transfer the liquid injection capsule 502 on the liquid injection capsule conveying line to the liquid injection capsule switching belt 50. The second capsule switching mechanism 70 is arranged behind the liquid injection capsule switching belt 50. The second capsule switching mechanism 70 is arranged at the top of the translation linear module 71. The translation linear module 71 is used to drive the second capsule switching mechanism 70 to move back and forth, that is, to move in the direction of approaching or moving away from the liquid injection capsule switching belt 50. The translation linear module 71 is a screw slide table, and the screw slide table is a conventional structure, and its structure will not be elaborated here. The liquid injection capsule NG belt 90 and the liquid injection capsule qualified belt 80 are both arranged on the right side of the translation linear module 71 and are arranged side by side in the front-rear direction. The second capsule switching mechanism 70 is used to transfer the liquid injection capsule 502 with qualified airtightness and the battery 501 inside the liquid injection capsule 502 to the liquid injection capsule qualified belt 80, and to transfer the liquid injection capsule 502 with unqualified airtightness and the battery 501 inside the liquid injection capsule 502 to the liquid injection capsule NG belt 90. The liquid injection capsule qualified belt 80 is used to convey the liquid injection capsule 502 with qualified airtightness and the battery 501 inside the liquid injection capsule 502 to the first static device. The liquid injection capsule NG belt 90 is used to convey the liquid injection capsule 502 with unqualified airtightness and the battery 501 inside the liquid injection capsule 502 to the NG station. The liquid injection capsule switching belt 50 is a roller chain conveyor belt. The roller chain conveyor belt is a conventional structure, and its structure will not be elaborated here. The roller chain 51 of the liquid injection capsule switching belt 50 has two, such as Figure 11As shown, two roller chains 51 are arranged at intervals. The structures of the qualified injection capsule pulling belt 80, the NG injection capsule pulling belt 90, and the injection capsule conveying line are the same as that of the injection capsule switching pulling belt 50. The qualified injection capsule pulling belt 80, the NG injection capsule pulling belt 90, and the injection capsule conveying line are respectively arranged at the top of a conveying rack. The lengths of the qualified injection capsule pulling belt 80, the NG injection capsule pulling belt 90, and the injection capsule conveying line are different from that of the injection capsule switching pulling belt 50. There are two qualified injection capsule pulling belts 80 in this embodiment, and the two qualified injection capsule pulling belts 80 are arranged side by side front and back.

[0038] The first capsule switching mechanism 40 includes a switching base 41, a hollow rotating platform 42, a switching bottom plate 44, a switching motor 43, a switching linear module 45, a switching frame 46, and a switching carrier plate 47. The hollow rotating platform 42 is an existing structure and is arranged at the top of the switching base 41. The switching bottom plate 44 is located above the hollow rotating platform 42 and is connected to the output end of the hollow rotating platform 42. The switching motor 43 is arranged on the hollow rotating platform 42 and the output shaft of the switching motor 43 is connected to the input end of the hollow rotating platform 42. The switching linear module 45 is a gear-rack sliding table module, and the gear-rack sliding table module is an existing structure, so its structure will not be elaborated here. The switching linear module 45 is arranged at the top of the switching bottom plate 44. One end of the switching frame 46 is open and the other end is closed. The switching frame 46 is located above the switching linear module 45. The bottom end of the switching frame 46 is connected to the top of the switching bottom plate 44 through two switching vertical plates 461. There are two switching vertical plates 461, and the switching linear module 45 is located between the two switching vertical plates 461. The length direction of the switching carrier plate 47 is the same as that of the switching frame 10. The switching carrier plate 47 is located above the switching linear module 45 and is connected to the switching linear module 45. The switching carrier plate 47 is located below the switching frame 46 and a part of the switching carrier plate 47 extends into the switching frame 46, and a part of the switching carrier plate 47 protrudes from the open end of the switching frame 46. The switching motor 43 is used to drive the switching bottom plate 44 to rotate through the hollow rotating platform 42, so as to drive the switching linear module 45 and drive the switching frame 46 to rotate through the two switching vertical plates 461, and further drive the switching carrier plate 47 to rotate. The switching linear module 45 is used to drive the switching carrier plate 47 to reciprocate along the length direction of the switching frame 46. In practical applications, the top of the switching carrier plate 47 of the first capsule switching mechanism 40 is flush with the tops of the two roller chains 51 of the injection capsule switching pulling belt 50 and the tops of the two roller chains of the injection capsule conveying line.

[0039] At positions near both ends of the switching carrier plate 47, two mounting grooves 475 are respectively provided at the top of the switching carrier plate 47. A first buckle 471a and a second buckle 471b are respectively provided in the two mounting grooves 475. The first buckle 471a and the second buckle 471b are arranged oppositely, and the first buckle 471a is located outside the switching frame 46. At one end of the mounting groove 475 away from the center of the switching carrier plate 47, two mounting hole positions 4751 are respectively provided on the inner walls on both sides. One end of the first buckle 471a (i.e., the end of the first buckle 471a away from the center of the switching carrier plate 47) is sleeved on the outer periphery of the first rotating shaft 473a. Both ends of the first rotating shaft 473a are rotatably arranged in the two mounting hole positions 4751 of the corresponding mounting groove 475. The other end of the first buckle 471a (i.e., the end of the first buckle 471a close to the center of the switching carrier plate 47) is inclined upward and connected to the bottom of the corresponding mounting groove 475 through a first elastic member 474a such as a spring. The first buckle 471a protrudes partially from the top of the switching carrier plate 47. One end of the second buckle 471b (i.e., the end of the second buckle 471b away from the center of the switching carrier plate 47) is sleeved on the outer periphery of the second rotating shaft 473b. Both ends of the second rotating shaft 473b are rotatably arranged in the two mounting hole positions 4751 of the corresponding mounting groove 475. The other end of the second buckle 471b (i.e., the end of the second buckle 471b close to the center of the switching carrier plate 47) is inclined upward and connected to the bottom of the corresponding mounting groove 475 through a second elastic member 474b such as a spring. The second buckle 471b protrudes partially from the top of the switching carrier plate 47. A clamping position 472 is formed between the first buckle 471a, the second buckle 471b and the top of the switching carrier plate 47. The second buckle 471b and the clamping position 472 are both located inside the switching frame 46.

[0040] At one end of the mounting groove 475 close to the center of the switching carrier plate 47, two limiting grooves 4712 are respectively provided on the inner walls on both sides. The limiting grooves 4712 extend to the top of the switching carrier plate 47. Two first limiting blocks 4711a are respectively formed on both sides of the other end of the first buckle 471a. The two first limiting blocks 4711a are respectively used to cooperate with the two limiting grooves 4712 of the corresponding mounting groove 475. When the two first limiting blocks 4711a respectively cooperate with the two limiting grooves 4712 of the corresponding mounting groove 475, the top of the first buckle 471a is flush with the top of the switching carrier plate 47. Two second limiting blocks 4711b are respectively formed on both sides of the other end of the second buckle 471b. The two second limiting blocks 4711b are respectively used to cooperate with the two limiting grooves 4712 of the corresponding mounting groove 475. When the two second limiting blocks 4711b cooperate with the two limiting grooves 4712 of the corresponding mounting groove 475, the top of the second buckle 471b is flush with the top of the switching carrier plate 47.

[0041] The structure of the second capsule switching mechanism 70 is the same as that of the first capsule switching mechanism 40, and also includes a switching base 41, a hollow rotating platform 42, a switching bottom plate 44, a switching motor 43, a switching linear module 45, a switching frame 46, and a switching carrier plate 47. The structure of the second capsule switching mechanism 70 will not be elaborated here. The difference between the second capsule switching mechanism 70 and the first capsule switching mechanism 40 is only that the switching base 41 of the second capsule switching mechanism 70 is arranged at the top of the translation linear module 71, and the height of the switching base 41 of the second capsule switching mechanism 70 is less than the height of the switching base 41 of the first capsule switching mechanism 40. In practical applications, the top of the switching carrier plate 47 of the second capsule switching mechanism 70 is flush with the tops of the two roller chains 51 of the liquid injection capsule switching belt 50, the tops of the two roller chains of the liquid injection capsule qualified belt 80, and the tops of the two roller chains of the liquid injection capsule NG belt.

[0042] With the above structure, in actual application, in the initial state, the opening of the switching frame 46 of the first capsule switching mechanism 40 faces the liquid injection capsule conveying line, and the opening of the switching frame 46 of the second capsule switching mechanism 70 faces the liquid injection capsule switching belt 50. When the liquid injection capsule 502 conveyed through the liquid injection capsule conveying line is about to reach the end of the liquid injection capsule conveying line close to the first capsule switching mechanism 40, the first capsule switching mechanism 40 operates: S1. First, the switching linear module 45 drives the switching carrier plate 47 to move towards the liquid injection capsule conveying line, so that the switching carrier plate 47 partially extends between the two roller chains of the liquid injection capsule conveying line. At this time, the clamping position 472 is outside the switching frame 46, the first buckle 471a is between the two roller chains of the liquid injection capsule conveying line, and the second buckle 471b is inside the switching frame 46. When the liquid injection capsule 502 moves to the position corresponding to the first buckle 471a driven by the rotation of the two roller chains of the liquid injection capsule conveying line, the liquid injection capsule 502 will squeeze the first buckle 471a. At this time, the first elastic member 474a is compressed, and the first buckle 471a can rotate downward relative to the switching carrier plate 47 until the two first limiting blocks 4711a of the first buckle 471a cooperate with the corresponding two limiting slots 4712. When the liquid injection capsule 502 moves into the clamping position 472, the liquid injection capsule 502 has moved into place. At this time, the liquid injection capsule 502 is separated from the two roller chains of the liquid injection capsule conveying line. Since the first buckle 471a is not squeezed by the liquid injection capsule 502, under the reset action of the first elastic member 474a, the first buckle 471a can rotate upward relative to the switching carrier plate 47 to the initial position. In this way, the liquid injection capsule 502 can be limited by the first buckle 471a and the second buckle 471b. Then, the switching linear module 45 drives the switching carrier plate 47 to move away from the liquid injection capsule conveying line to return to the initial position, so as to drive the liquid injection capsule 502 to move into the switching frame 46 through the opening of the switching frame 46. In this way, the liquid injection capsule 502 can be fixed by the switching frame 46 to prevent the liquid injection capsule 502 from falling, as Figure 11As shown. S2. Then, by switching the motor 43, the hollow rotary platform 42 drives the switching linear module 45, the switching frame 46, and the switching carrier plate 47 to rotate, for example, 90 degrees in the clockwise direction, so as to drive the liquid injection capsule 502 to rotate 90 degrees. At this time, the opening of the switching frame 46 faces the liquid injection capsule switching strap 50. S3. Then, the switching linear module 46 drives the switching carrier plate 47 to move towards the liquid injection capsule switching strap 50, so that the switching carrier plate 47 partially extends between the two roller chains 51 of the liquid injection capsule switching strap 50. The movement of the switching carrier plate 47 can drive the liquid injection capsule 502 to move out of the switching frame 46 through the opening of the switching frame 46 and drive the liquid injection capsule 502 to move onto the two roller chains 51 of the liquid injection capsule switching strap 50. Then, the two roller chains 51 of the liquid injection capsule switching strap 50 can drive the liquid injection capsule 502 to move away from the first capsule switching mechanism 40. During the movement of the liquid injection capsule 502, the liquid injection capsule 502 will squeeze the first buckle 471a, so that the first elastic member 474a is compressed. The first buckle 471a can rotate downward relative to the switching carrier plate 47 until the two first limit blocks 4711a of the first buckle 471a cooperate with the corresponding two limit slots 4712. When the liquid injection capsule 502 is separated from the first buckle 471a, at this time, the first buckle 471a is not squeezed by the liquid injection capsule 502. Under the reset action of the first elastic member 474a, the first buckle 471a can rotate upward relative to the switching carrier plate 47 to the initial position. Then, the switching linear module 45 drives the switching carrier plate 47 to move away from the liquid injection capsule switching strap 50 to return to the initial position. The movement of the switching carrier plate 47 can drive the first buckle 471a and the second buckle 471b to move synchronously. At the same time, the two roller chains 51 of the liquid injection capsule switching strap 50 drive the liquid injection capsule 502 to move away from the center of the switching carrier plate 47. In this way, through the first capsule switching mechanism 40, the liquid injection capsule 502 on the liquid injection capsule conveying line is transferred to the liquid injection capsule switching strap 50.

[0043] Then, the first capsule switching mechanism 40 transfers the next liquid injection capsule 502 on the liquid injection capsule conveying line to the liquid injection capsule switching strap 50 according to the foregoing steps. In this way, the liquid injection capsule 502 can be conveyed to the buckle-taking cup manipulator 30 through the liquid injection capsule switching strap 50.

[0044] After the first liquid injection into the battery 501 through the first liquid injection device, the battery discharging manipulator 40 operates as follows: First, the two battery discharging jaws 27 are driven by the battery discharging translation motor 22 to move rightward above the battery 501. Then, the two battery discharging jaws 27 are driven by the battery discharging lifting cylinder 23 to move downward so that the two battery discharging jaws 27 are respectively located in front of and behind the top of the battery 501. Then, the two battery discharging jaws 27 are driven by the two battery discharging jaw cylinders 26 to move closer to each other to clamp the battery 501. Then, the two battery discharging jaws 27 are driven by the battery discharging lifting cylinder 23 to move upward and the two battery discharging jaws 27 are driven by the battery discharging translation motor 22 to move leftward, thereby driving the battery 501 to move leftward. Before the two battery discharging jaws 27 are driven by the battery discharging lifting cylinder 23 to move downward, if the positions of the two battery discharging jaws 27 are offset relative to the battery 501, for example, forward offset, then the battery discharging deviation correction motor 28 is first driven to rotate the battery discharging deviation correction screw rod 281, so that the battery discharging lifting cylinder 23 can be driven to move backward through the battery discharging deviation correction nut 282, thereby driving the two battery discharging jaws 27 to move backward until the positions of the two battery discharging jaws 27 are not offset relative to the battery 501. Then, the two battery discharging jaws 27 are driven by the battery discharging lifting cylinder 23 to move downward so that the two battery discharging jaws 27 are respectively located in front of and behind the top of the battery 501. By setting the battery discharging deviation correction mechanism, the positions of the two battery discharging jaws 27 can be corrected to ensure that the two battery discharging jaws 27 can successfully clamp the battery 501 after the first liquid injection.

[0045] When two liquid injection capsules 502 reach below the cup-removing manipulator 30, the cup-removing manipulator 30 operates as follows: First, it drives the two cup-removing jaw groups to move downward through the cup-removing lifting cylinder 33, so that the first cup-removing jaws 371 and the second cup-removing jaws 372 of the two cup-removing jaw groups are respectively located on the left and right sides of the cup 5022 of the two liquid injection capsules 502. Then, it drives the first cup-removing jaws 371 and the second cup-removing jaws 372 of the two cup-removing jaw groups to approach each other through the two cup-removing jaw cylinders 35, so that the two cup-removing jaw groups can clamp the cups 5022 of the two liquid injection capsules 502. Then, it drives the two cup-removing jaw groups to move upward through the cup-removing lifting cylinder 33, and drives the two cup-removing jaw groups to move leftward through the cup-removing translation motor 32, so that the cups 5022 of the two liquid injection capsules 502 are respectively located above the lower cavities 5021 of the two liquid injection capsules 502 and on the left sides of the lower cavities 5021 of the two liquid injection capsules 502. In this way, the cup 5022 of the liquid injection capsule 502 is removed from the top of the lower cavity 5021 of the liquid injection capsule 502. When the battery 501 is driven by the battery-placement manipulator 20 to move leftward to above the lower cavity 5021 of one of the liquid injection capsules 502, it drives the two battery-placement jaws 27 to move downward through the battery-placement lifting cylinder 23, so that the battery 501 is placed inside the inner cavity of the lower cavity 5021 of one of the liquid injection capsules 502. At this time, a part of the battery 501 protrudes from the top of the lower cavity 5021 of one of the liquid injection capsules 502. Then, it drives the two battery-placement jaws 27 to move away from each other to release the battery 501 through the two battery-placement jaw cylinders 26 and drives the two battery-placement jaws 27 to move upward through the battery-placement lifting cylinder 23. Then, it drives the two battery-placement jaws 27 to move rightward through the battery-placement translation motor 22. Then, it drives the next battery 501 after the first liquid injection to move to above the lower cavity 5021 of the other liquid injection capsule 502 according to the foregoing steps, and then places the next battery 501 after the first liquid injection inside the inner cavity of the lower cavity 5021 of the other liquid injection capsule 502 according to the foregoing steps. Then, it drives the two cup-removing jaw groups to move rightward through the cup-removing translation motor 32, so that the cups 5022 of the two liquid injection capsules 502 are respectively located above the lower cavities 5021 of the two liquid injection capsules 502. Then, it drives the two cup-removing jaw groups to move downward through the cup-removing lifting cylinder 34 to respectively cover the cups 5022 of the two liquid injection capsules 502 on the tops of the lower cavities 5021 of the two liquid injection capsules 502, and makes the part of the battery 501 protruding from the top of the corresponding lower cavity 5021 of the liquid injection capsule 502 be located inside the second inner cavity of the corresponding cup 5022 of the liquid injection capsule 502, and the liquid injection port of the battery 501 is matched with the lower end of the liquid injection nozzle 5025 of the corresponding cup 5022, as Figure 2As shown. Then, two pick-up cup gripper cylinders 35 drive the first pick-up cup grippers 371 and the second pick-up cup grippers 372 of the two pick-up cup gripper groups to move away from each other, so that the two pick-up cup gripper groups can loosen the cup buckles 5022 of the two liquid injection capsules 502. Then, the pick-up cup lifting cylinder 34 drives the two pick-up cup gripper groups to move upward. In this way, the two batteries 501 after the first liquid injection are respectively placed into the two liquid injection capsules 502. Then, the liquid injection capsule switching strap 50 transports the two liquid injection capsules 502 and the batteries 501 in the two liquid injection capsules 502 to the capsule airtightness detection mechanism 60.

[0046] When the two liquid injection capsules 502 and the batteries 501 in the two liquid injection capsules 502 reach below the capsule airtightness detection mechanism 60, the capsule airtightness detection mechanism 60 operates: The detection lifting cylinder 64 drives the third detection plate 63 to move downward, so as to drive the two nozzle groups and the two plugs 66 to move downward until the two nozzles 65 of the nozzle group and the plugs 66 are matched with the two air inlets 5023 and the liquid injection ports 5026 of the corresponding liquid injection capsules 502. Then, the vacuum pumping device evacuates the first inner cavity of the cup buckle 5022 of the corresponding liquid injection capsule 502 through the vacuum pipeline, the two connection joints 651, the two vacuum pumping holes, and the two nozzles 65 of the nozzle group. After that, observe the changes of the two values respectively corresponding to the two liquid injection capsules 502 on the pressure gauge 67. If the values do not change within the predetermined time, it indicates that the first inner cavity of the cup buckle 5022 of the corresponding liquid injection capsule 502 is airtight, and the airtightness of the liquid injection capsule 502 is qualified. If the values change, it indicates that the airtightness of the corresponding liquid injection capsule 502 is unqualified. Then, the detection lifting cylinder 64 drives the third detection plate 63 to move upward, so as to drive the two nozzles 65 of the two nozzle groups and the two plugs 66 to move upward, so that the two nozzles 65 of the nozzle group and the plugs 66 are separated from the air inlets 5023 and the liquid injection ports 5026 of the corresponding liquid injection capsules 502.

[0047] Then, the liquid injection capsule switching strap 50 continues to transport the liquid injection capsules 502 with the airtightness detection completed and the batteries 501 in the liquid injection capsules 502 to the second capsule switching mechanism 70.

[0048] The structure of the second capsule switching mechanism 70 is the same as that of the first capsule switching mechanism 40. The second capsule switching mechanism 70 operates as follows: S11. First, the switching linear module 45 of the second capsule switching mechanism 70 drives the switching carrier plate 47 to move towards the liquid injection capsule switching belt 50, so that the switching carrier plate 47 partially extends between the two roller chains 51 of the liquid injection capsule switching belt 50. At this time, the clamping position 472 is outside the switching frame 46, the first buckle 471a is between the two roller chains 51 of the liquid injection capsule switching belt 50, and the second buckle 471b is inside the switching frame 46. When the liquid injection capsule 502 moves to the position corresponding to the first buckle 471a driven by the rotation of the two roller chains 51 of the liquid injection capsule switching belt 50, the liquid injection capsule 502 will squeeze the first buckle 471a. At this time, the first elastic member 474a is compressed, and the first buckle 471a can rotate downward relative to the switching carrier plate 47 until the two first limiting blocks 4711a of the first buckle 471a cooperate with the corresponding two limiting slots 4712. When the liquid injection capsule 502 moves into the clamping position 472, the liquid injection capsule 502 has moved in place. At this time, the liquid injection capsule 502 is separated from the two roller chains 51 of the liquid injection capsule switching belt 50. Since the first buckle 471a is not squeezed by the liquid injection capsule 50, under the reset action of the first elastic member 474a, the first buckle 471a can rotate upward relative to the switching carrier plate 47 to the initial position. In this way, the liquid injection capsule 502 can be limited by the first buckle 471a and the second buckle 471b. Then, the switching linear module 45 drives the switching carrier plate 47 to move away from the liquid injection capsule switching belt 50 to return to the initial position, so as to drive the liquid injection capsule 502 to move into the switching frame 46 through the opening of the switching frame 46. In this way, the liquid injection capsule 502 can be fixed by the inner walls on both sides of the switching frame 46 to prevent the liquid injection capsule 502 from falling. S12. When the airtightness of the liquid injection capsule 502 is qualified, first, the translation linear module drives the second capsule switching mechanism 70 to move backward (i.e., move away from the liquid injection capsule switching belt 50) until the second capsule switching mechanism 70 corresponds to the liquid injection capsule qualified belt 80. S13. Then, the switching motor 43 and the hollow rotary platform 42 drive the switching linear module 45, the switching frame 46, and the switching carrier plate 47 to rotate 90 degrees, for example, in the counterclockwise direction, so as to drive the liquid injection capsule 502 and the battery 501 inside the liquid injection capsule 502 to rotate 90 degrees. At this time, the opening of the switching frame 46 faces the liquid injection capsule qualified belt 80.S14. Then, drive the switching carrier plate 47 to move towards the direction close to the qualified pulling belt 80 of the liquid injection capsule through the switching linear module 46, so that a part of the switching carrier plate 47 extends into the space between the two roller chains 51 of the qualified pulling belt 80 of the liquid injection capsule. The movement of the switching carrier plate 47 can drive the liquid injection capsule 502 and the battery 501 inside the liquid injection capsule 502 to move out of the switching frame 46 through the opening of the switching frame 46, and can drive the liquid injection capsule 502 and the battery 501 inside the liquid injection capsule 502 to move onto the two roller chains 51 of the qualified pulling belt 80 of the liquid injection capsule. After that, the two roller chains 51 of the qualified pulling belt 80 of the liquid injection capsule can drive the liquid injection capsule 502 and the battery 501 inside the liquid injection capsule 502 to move away from the second capsule switching mechanism 70. During the movement of the liquid injection capsule 502 and the battery 501 inside the liquid injection capsule 502, the liquid injection capsule 502 presses against the first buckle 471a, so that the first elastic member 474a is compressed. The first buckle 471a can rotate downward relative to the switching carrier plate 47 until the two first limiting blocks 4711a of the first buckle 471a are engaged with the corresponding two limiting slots 4712. When the liquid injection capsule 502 is separated from the first buckle 471a, at this time, the first buckle 471a is not pressed by the liquid injection capsule 502. Under the reset action of the first elastic member 474a, the first buckle 471a can rotate upward relative to the switching carrier plate 47 to the initial position. Then, drive the switching carrier plate 47 to move away from the qualified pulling belt 80 of the liquid injection capsule through the switching linear module 45 to return to the initial position. The movement of the switching carrier plate 47 can drive the first buckle 471a and the second buckle 471b to move synchronously. In this way, through the second capsule switching mechanism 70, the liquid injection capsule 502 with qualified airtightness and the battery 501 inside the liquid injection capsule 502 are transferred onto the qualified pulling belt 80 of the liquid injection capsule. Through the qualified pulling belt 80 of the liquid injection capsule, the liquid injection capsule 502 and the battery 501 inside the liquid injection capsule 502 can be transported to the first static device for high-temperature + positive and negative pressure cyclic static treatment.

[0049] S15: When the airtightness of the liquid injection capsule 502 is unqualified, first drive the second capsule switching mechanism 70 to move backward through the translation linear module 71 until the second capsule switching mechanism 70 corresponds to the liquid injection capsule NG pulling belt 90. S16: Then drive the switching linear module 45, the switching frame 46 and the switching carrier plate 47 to rotate, for example, 90 degrees counterclockwise through the switching motor 43 and the hollow rotating platform 42, so as to drive the liquid injection capsule 502 and the battery 501 in the liquid injection capsule 502 to rotate 90 degrees. At this time, the opening of the switching frame 46 faces the liquid injection capsule NG pulling belt 90. S17: Then drive the switching carrier plate 47 to move towards the direction close to the liquid injection capsule NG pulling belt 90 through the switching linear module 46, so that a part of the switching carrier plate 47 extends into the space between the two roller chains 51 of the liquid injection capsule NG pulling belt 90. The movement of the switching carrier plate 47 can drive the liquid injection capsule 502 and the battery 501 in the liquid injection capsule 502 to move out of the switching frame 46 through the opening of the switching frame 46, and can drive the liquid injection capsule 502 and the battery 501 in the liquid injection capsule 502 to move onto the two roller chains 51 of the liquid injection capsule NG pulling belt 90. During the movement of the liquid injection capsule 502 and the battery 501 in the liquid injection capsule 502, the liquid injection capsule 502 will squeeze the first buckle 471a, so that the first elastic member 474a is compressed, and the first buckle 471a can rotate downward relative to the switching carrier plate 47 until the two first limiting blocks 4711a of the first buckle 471a cooperate with the corresponding two limiting slots 4712. When the liquid injection capsule 502 is separated from the first buckle 471a, at this time, the first buckle 471a is not squeezed by the liquid injection capsule 502. Under the reset action of the first elastic member 474a, the first buckle 471a can rotate upward relative to the switching carrier plate 47 to the initial position. Then drive the switching carrier plate 47 to move away from the liquid injection capsule NG pulling belt 90 through the switching linear module 45 to return to the initial position. The movement of the switching carrier plate 47 can drive the first buckle 471a and the second buckle 471b to move synchronously. In this way, through the second capsule switching mechanism 70, the liquid injection capsule 502 with unqualified airtightness and the battery 501 in the liquid injection capsule 502 are transferred onto the liquid injection capsule NG pulling belt 90, and the liquid injection capsule 502 and the battery 501 in the liquid injection capsule 502 can be transported to the NG station through the liquid injection capsule NG pulling belt 90 for blanking.

[0050] Then transfer the next liquid injection capsule 502 on the liquid injection capsule switching pulling belt 50 and the battery 501 in the liquid injection capsule 502 to the corresponding pulling belt through the second capsule switching mechanism 70 according to the foregoing steps.

[0051] With the battery placing manipulator 20 and the buckle cup taking manipulator 30 provided in the present utility model, the battery 501 after the first liquid injection can be automatically placed into the liquid injection capsule 502. Compared with the existing manual method, the production efficiency is greatly improved, and the labor intensity and production cost of manual labor are reduced. The capsule airtightness detection mechanism 60 can detect the airtightness of the liquid injection capsule 502 after the battery 501 after the first liquid injection is placed into the liquid injection capsule 502, so as to prevent air leakage of the liquid injection capsule 502, which is convenient for subsequent alternately evacuating the inside of the battery 501 and introducing nitrogen through the first inner cavity of the buckle cup 5022 of the liquid injection capsule 502 and the liquid injection nozzle 5025 by the first static device, so as to realize the high-temperature + positive and negative pressure cyclic static treatment of the battery 501 in the liquid injection capsule 502. Through the first capsule switching mechanism 40 provided, the liquid injection capsule 502 on the liquid injection capsule conveying line can be transferred to the liquid injection capsule switching belt 50. In this way, through the liquid injection capsule switching belt 50, the liquid injection capsule 502 can be conveyed to the buckle cup taking manipulator 30, the liquid injection capsule 502 and the battery 501 in the liquid injection capsule 502 can be conveyed to the capsule airtightness detection mechanism 60, and after the airtightness of the liquid injection capsule 502 is detected by the capsule airtightness detection mechanism 60, the liquid injection capsule 502 and the battery 501 in the liquid injection capsule 502 can be conveyed to the second capsule switching mechanism 70. Through the second capsule switching mechanism 70 and the translation linear module 71, the liquid injection capsule 502 with qualified airtightness and the battery 501 in the liquid injection capsule 502 can be transferred to the qualified liquid injection capsule belt 80, and the liquid injection capsule 502 with unqualified airtightness and the battery 501 in the liquid injection capsule 502 can be transferred to the NG liquid injection capsule belt 90. The degree of automation is high and does not require manual operation, further improving the production efficiency and reducing the production cost.
