[0038] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0039] As described in the background section, there are shortcomings in the existing technology. In order to solve the above-mentioned technical problems, this application proposes a sealing performance testing device and a testing method for new energy battery processing.

[0040] Example 1:

[0041] Please see Figure 1 - Figure 10A sealing test device includes a device body 1, a discharge roller 3 and an explosion-proof valve sealing mechanism 5. The discharge roller 3 is installed inside the device body 1, the explosion-proof valve sealing mechanism 5 is installed on the top of the device body 1, the feeding roller 2 is installed inside the device body 1, and the discharge roller 3 is installed inside the device body 1.

[0042] The power port sealing mechanism 4 is installed between the feeding roller 2 and the discharging roller 3. The power port sealing mechanism 4 includes a battery limiting frame 41 and a power port sealing block 42. The battery limiting frame 41 is slidably installed inside the main body 1 of the device, and the power port sealing block 42 is slidably installed inside the battery limiting frame 41.

[0043] The explosion-proof valve sealing mechanism 5 includes a connecting port movable rod 51, an explosion-proof valve connecting port 52, and a battery transmission plate 57. The connecting port movable rod 51 is slidably installed inside the device body 1, the explosion-proof valve connecting port 52 is fixedly installed at the bottom of the connecting port movable rod 51, and the battery transmission plate 57 is slidably installed inside the device body 1.

[0044] The feeding roller 2 and the discharging roller 3 can drive the new energy battery to move inside the main body 1 of the device. When the new energy battery moves, it can drive the battery transmission plate 57 to move inside the main body 1 of the device. When the battery transmission plate 57 moves, it can drive the connecting port movable rod 51 to move up and down inside the main body 1 of the device. When the main body 1 of the device moves downward, it can drive the explosion-proof valve connecting port 52 to seal the explosion-proof valve port of the new energy battery. The power port sealing block 42 can seal the power port of the new energy battery. After the position of the battery limit frame 41 drops, the feeding roller 2 can move the new energy battery onto the discharging roller 3.

[0045] During operation, the new energy battery to be tested is first placed on the feeding roller 2. The feeding roller 2 can drive the new energy battery to move towards the power port sealing mechanism 4. During the movement of the new energy battery, the protrusion on the new energy battery can drive the battery transmission plate 57 to move. When the battery transmission plate 57 moves, it can drive the position of the connecting port movable rod 51 to drop. When the position of the connecting port movable rod 51 drops, it can drive the position of the explosion-proof valve connecting port 52 to drop. When the new energy battery contacts the battery limit frame 41, the power port sealing block 42 can seal the power port of the new energy battery. And when the position of the connecting port movable rod 51 drops, it can drive the explosion-proof valve connecting port 52 to seal the explosion-proof valve port of the new energy battery. Then the sealing tester 54 can then... The sealing performance of the new energy battery is tested internally. After the test is completed, the position of the power port sealing block 42 drops. After the position of the power port sealing block 42 drops, the feeding roller 2 can move the new energy battery onto the discharge roller 3, and then the new energy battery is removed. During the process of the feeding roller 2 moving the new energy battery, it can drive the explosion-proof valve connection port 52 and the power port sealing block 42 to seal the explosion-proof valve port and power port of the new energy battery. Furthermore, the connection between the explosion-proof valve connection port 52 and the explosion-proof valve port of the new energy battery enables the sealing performance tester 54 to communicate with the inside of the new energy battery. This allows the sealing performance of the new energy battery to be tested from the inside, thus preventing the minor faults of the external environment and equipment from affecting the test results.

[0046] Example 2:

[0047] The difference from the above embodiments is that, please refer to [link / reference needed]. Figure 2 - Figure 4 The power port sealing mechanism 4 includes a limit frame lifting rod 46, which is fixedly installed inside the main body 1 of the device. A sealing block baffle 43 is installed on the top of the power port sealing block 42. A sealing block spring 44 is fixedly installed on the outside of the battery limit frame 41. A sealing block sliding chamber 45 is fixedly installed on the outside of the battery limit frame 41.

[0048] The fixed end of the limit frame lifting rod 46 is fixedly connected to the bottom of the device body 1, and the movable end of the limit frame lifting rod 46 is fixedly connected to the bottom of the battery limit frame 41. The battery limit frame 41 is slidably installed inside the device body 1 through the limit frame lifting rod 46.

[0049] The power port sealing block 42 is slidably connected to the inside of the battery limiting frame 41. One side of the power port sealing block 42 is provided with a sealing port that fits the power port of the new energy battery. The other side of the power port sealing block 42 is fixedly connected to the inside of the sealing block sliding chamber 45 through the sealing block spring 44.

[0050] The power port sealing block 42 can seal the new energy power port when it comes into contact with the new energy battery power port, and can drive the power port sealing block 42 to move towards the sealing block sliding chamber 45 when the new energy battery moves.

[0051] The two sides of the battery limiting frame 41 are attached to the inner sidewall of the device body 1. The part of the battery limiting frame 41 that contacts the device body 1 is provided with an inclined structure. The protrusion at the bottom of the battery limiting frame 41 can engage with the protrusion on the outside of the new energy battery.

[0052] During operation, the feeding roller 2 drives the new energy battery to move towards the battery limiting frame 41. As the new energy battery moves, the tilted structure on both sides of the battery limiting frame 41 limits its position. As the new energy battery continues to move, its power port contacts the inside of the power port sealing block 42, sealing the power port. The battery's sealing performance is then tested. After the test, the new energy battery continues to move, causing the explosion-proof valve sealing mechanism 5 to contact the sealing block baffle 43 on the power port sealing block 42. This seals the power port. The valve sealing mechanism 5 pushes the power port sealing block 42 towards the sealing block sliding chamber 45. As the power port sealing block 42 moves towards the sealing block sliding chamber 45, it releases the sealing connection with the new energy battery, causing the sealing block spring 44 to contract. Then, the limit frame lifting rod 46 lowers the position of the battery limit frame 41, and the power port sealing mechanism 4 rebounds, causing the power port sealing block 42 to move towards the feeding roller 2. The feeding roller 2 then moves the new energy battery onto the discharge roller 3. During the movement of the new energy battery, the battery limit frame 41 seals the power port of the new energy battery. After testing, the mechanism can be retracted to facilitate the movement of the new energy battery to the next stage.

[0053] Example 3:

[0054] The difference from the above embodiments is that, please refer to [link / reference needed]. Figure 5 - Figure 10The explosion-proof valve sealing mechanism 5 includes a connecting port movable rod 51, a sealing tester 54, and a locking block limiting plate 511. The connecting port movable rod 51 is slidably installed inside the device body 1. The sealing tester 54 is fixedly installed on the top of the device body 1. The locking block limiting plate 511 is fixedly installed inside the device body 1. The bottom of the connecting port movable rod 51 is fixedly connected to the explosion-proof valve connecting port 52. The top of the connecting port movable rod 51 is fixedly connected to the detection connecting pipe 53. The outside of the connecting port movable rod 51 is fixedly installed with a movable rod limiting ring 55. The top of the movable rod limiting ring 55 is fixedly installed with a movable rod spring 56. The top of the battery transmission plate 57 is fixedly installed with an interface limiting block 58. The inside of the battery transmission plate 57 is provided with a transmission plate groove 59. One end of the battery transmission plate 57 is rotatably connected to a movable locking block 510. The inside of the battery transmission plate 57 is installed with a transmission plate spring 512.

[0055] The movable rod limiting ring 55 outside the connecting port movable rod 51 is connected to the device body 1 through the movable rod spring 56, and the top of the battery transmission plate 57 contacts the bottom of the movable rod limiting ring 55 through the interface limiting block 58.

[0056] When the battery transmission plate 57 moves, it can contact the movable rod limit ring 55 through the interface limit block 58 to drive the movable rod 51 of the connection port to move up and down. When the movable rod 51 of the connection port moves down, it can drive the explosion-proof valve connection port 52 to move down. When the explosion-proof valve connection port 52 descends, it can seal the explosion-proof valve port of the new energy battery.

[0057] One end of the connecting port movable rod 51 is connected to the sealing tester 54 through the detection connecting tube 53, and the other end of the connecting port movable rod 51 passes through the device body 1 and the battery transmission plate 57 and is fixedly connected to the explosion-proof valve connecting port 52.

[0058] When the explosion-proof valve connection port 52 seals the explosion-proof valve port of the new energy battery, the sealing tester 54 can communicate with the inside of the new energy battery through the test connection pipe 53, the connection port movable rod 51 and the explosion-proof valve connection port 52.

[0059] The bottom of the locking plate 511 has a protrusion that inserts into the inside of the transmission plate groove 59. One end of the transmission plate spring 512 is connected to the inside of the transmission plate groove 59, and the other end of the transmission plate spring 512 is connected to the bottom protrusion of the locking plate 511. The battery transmission plate 57 is slidably connected to the locking plate 511 through the transmission plate spring 512.

[0060] The movable block 510 is rotatably connected to one end of the battery transmission plate 57. The top of the movable block 510 is in contact with the bottom of the block limiting plate 511. The movable block 510 is provided with a protrusion that engages with the block limiting plate 511 on the side away from the battery transmission plate 57.

[0061] The battery transmission plate 57 is engaged with the protrusion on the new energy battery via the movable block 510. When the top of the movable block 510 contacts the bottom of the block limiting plate 511, the movable block 510 cannot rotate. When the movable block 510 is separated from the block limiting plate 511, the movable block 510 can rotate around the connection point with the battery transmission plate 57.

[0062] The feeding roller 2 drives the new energy battery to move. The protrusion on the new energy battery can engage with the movable block 510 on the battery transmission plate 57. When the new energy battery moves, it can drive the battery transmission plate 57 to move from the initial position to the power port sealing mechanism 4. When the battery transmission plate 57 moves, it can compress the transmission plate spring 512. During the movement of the battery transmission plate 57, it can drive the interface limiting block 58 to move. When the interface limiting block 58 moves, it can engage with the movable rod limiting ring 55 to drive the connecting port movable rod 51 to move up and down. When the explosion-proof valve port of the new energy battery moves below the explosion-proof valve connection port 52, the interface limiting block 58 can drive the position of the connection port movable rod 51 to drop and seal the explosion-proof valve port of the new energy battery through the explosion-proof valve connection port 52. After the explosion-proof valve connection port 52 is connected to the explosion-proof valve port of the new energy battery, the sealing tester 54 can communicate with the inside of the new energy battery through the detection connection pipe 53 and the connection port movable rod 51. Then, the sealing performance of the new energy battery is detected from the inside of the new energy battery through the connection port movable rod 51. After the test is completed, the new energy battery moves a small distance, causing the movable block 510 to disengage from the protrusion on the new energy battery. The movable locking block 510 rotates around the connection point with the battery transmission plate 57, and the movable locking block 510 can contact the sealing block baffle 43 when rotating. The sealing block baffle 43 pushes the power port sealing block 42 to move towards the sealing block sliding chamber 45. After the movable locking block 510 rotates, the new energy battery moves onto the discharge roller 3. Then the transmission plate spring 512 rebounds and drives the battery transmission plate 57 back to the initial position. During the operation, the movement of the new energy battery can drive the explosion-proof valve connection port 52 to seal the explosion-proof valve port of the new energy battery, so that the sealing performance of the new energy battery can be quickly tested during the processing of the new energy battery.

[0063] Example 4:

[0065] During operation, the new energy battery is first placed on the feeding roller 2, and the feeding roller 2 drives the new energy battery to move towards the power port sealing mechanism 4.

[0066] During the movement of the new energy battery, the power port sealing block 42 and the explosion-proof valve connection port 52 can respectively seal the power port and the explosion-proof valve port of the new energy battery.

[0067] The sealing tester 54 can test the sealing performance of new energy batteries by communicating with the inside of the new energy battery through the explosion-proof valve port;

[0068] After the test is completed, the position of the battery limit frame 41 is lowered, and the feeding roller 2 moves the new energy battery onto the discharge roller 3.
