[0066] like Figures 1 to 6 As shown, a lithium battery testing device includes a testing platform 1, a testing assembly is provided on the top of the testing platform 1, a guiding mechanism is provided on one side of the testing platform 1, a first conveyor 2 is provided between the guiding mechanism and the testing assembly, and the guiding mechanism includes:

[0067] The mounting platform 3 has a turntable 4 inside, and the turntable 4 is provided on the top of the mounting platform 3;

[0068] A conveyor tray is provided on the top of the turntable 4, the conveyor tray is fixedly connected to the turntable of the turntable 4, and the conveyor tray can drive the lithium batteries to move to the first conveyor 2;

[0069] A mounting frame 5 is provided on top of the conveyor tray;

[0070] A driving member is mounted on the top of the installation frame 5, the driving member is in transmission connection with the top of the installation frame 5, and the driving member is used to drive the installation frame 5 to move up and down;

[0071] The straightening assembly is arranged on the installation frame 5 and is used to drive any placed lithium battery to adjust to a state where the electrodes face upwards.

[0072] Among them, when the alignment component adjusts the lithium battery to the electrode facing upward, the turntable 4 drives the conveyor disc to rotate, and the conveyor disc drives the lithium battery to rotate until the electrode faces the detection component, so that the detection component can quickly cooperate with the lithium battery to perform detection work.

[0073] By placing the lithium battery on the conveyor disc, the installation frame 5 is driven downward by the driving member, the alignment component is driven downward by the installation frame 5, and the lithium battery is guided by the alignment component, so that the electrode of the lithium battery is set upward, the conveyor disc is driven to rotate by the turntable 4, and the lithium battery is driven to rotate by the conveyor disc, so that the electrode of the lithium battery is set toward the first conveyor 2, and the lithium battery is driven to move onto the first conveyor 2 by the conveyor disc, and the lithium battery is driven to move under the detection component of the detection table 1 by the first conveyor 2, so that the detection component can quickly cooperate with the electrode of the lithium battery to complete the detection work, thereby solving the problem that the lithium battery needs to be manually aligned and adjusted before detection, which is not only time-consuming and labor-intensive, but also inefficient.

[0074] As an optional embodiment, the conveyor tray includes:

[0075] A base 6 is fixedly connected to the turntable of the turntable 4;

[0076] The disc 7 is arranged on the top of the base 6 , the disc 7 is fixedly connected to the base 6 , and at least two electric pulley sets 8 are passed through the disc 7 .

[0077] For example, the base 6 is driven to rotate by the turntable 4, the disc 7 is driven to rotate by the base 6, and the lithium battery is driven to rotate by the disc 7, so that the lithium battery can complete the horizontal rotation and correction work. By arranging an electric pulley group 8 on the disc 7, the lithium battery can be quickly moved to the first conveyor 2 after correction, thereby realizing the horizontal rotation, correction and transportation of the lithium battery.

[0078] As an optional embodiment, the driving member is an electric hydraulic rod 9, which is arranged on the top of the mounting frame 5 through a gantry 10. A fixed plate 11 is provided on the top of the gantry 10. The electric hydraulic rod 9 is mounted on the fixed plate 11. The telescopic rod of the electric hydraulic rod 9 passes through the fixed plate 11 and is fixedly connected to the mounting frame 5. A limiting rod 12 is provided on the side of the electric hydraulic rod 9, and one end of each limiting rod 12 passes through the fixed plate 11 and is fixedly connected to the mounting frame 5.

[0079] For example, the electric hydraulic rod 9 drives the installation frame 5 to move downward, and the installation frame 5 drives the alignment component to move downward, so that the alignment component can guide the electrodes of the lithium battery upward. By setting the limit rod 12, the installation frame 5 will not rotate with the electric hydraulic rod 9 during the movement, thereby achieving the problem of driving the alignment component to work close to the lithium battery.

[0080] As an optional embodiment, the interior of the mounting frame 5 has two layers, and a detection camera 13 for controlling the operation of the alignment assembly is provided at the bottom of the mounting frame 5. The alignment assembly includes:

[0081] A limiting frame 14 is provided in the top layer of the installation frame 5;

[0082] A first motor 15 is mounted on the top of the limiting frame 14 , and an output shaft of the first motor 15 passes through the top of the limiting frame 14 ;

[0083] A threaded rod 16 is provided inside the limiting frame 14 , one end of the threaded rod 16 is fixedly connected to the output shaft of the first motor 15 , and the other end is hinged to the bottom of the top layer of the mounting frame 5 ;

[0084] An adjustment plate 17 is disposed inside the limiting frame 14 , one end of the adjustment plate 17 is sleeved on the threaded rod 16 , and the adjustment plate 17 is threadedly connected to the threaded rod 16 ;

[0085] A second motor 18 is mounted on top of the adjustment plate 17;

[0086] A connecting shaft 19 is hinged on the end of the adjusting plate 17 away from the threaded rod 16, and one end of the connecting shaft 19 is fixedly connected to the output shaft of the second motor 18, and the other end is passed through the bottom of the mounting frame 5;

[0087] A first gear 20 is provided inside the bottom layer of the mounting frame 5 and is fixedly connected and sleeved on the connecting shaft 19;

[0088] A second gear 21 is provided at the bottom of the mounting frame 5 and is fixedly connected and sleeved on the connecting shaft 19;

[0089] Two first racks 22 are slidably connected to the bottom of the bottom layer of the mounting frame 5. Each of the first racks 22 moves downward through the connecting shaft 19 to engage with the first gear 20. A first guide plate 23 is extended downward from one end of the two first racks 22 away from each other.

[0090] Two second racks 24 are slidably connected to the bottom of the mounting frame 5. Each second rack 24 moves upward through the connecting shaft 19 to engage with the second gear 21. A second guide plate 25 extends downward from one end of the two second racks 24 away from each other, and the two second guide plates 25 are staggered with the two first guide plates 23.

[0091] Two rotating plates 26 are hinged on the sides of the two second guide plates 25 that are close to each other. A third motor 27 is mounted on the side of one of the second guide plates 25 away from the rotating plate 26, and the output shaft of the third motor 27 is fixedly connected to the rotating plate 26.

[0092] For example, the electrode position of the lithium battery on the disk 7 is observed by the detection camera 13. When the electrode of the lithium battery is at the side or bottom position, the threaded rod 16 is driven to rotate by the first motor 15, and the adjustment plate 17 is driven downward by the threaded rod 16. The connecting shaft 19 is driven downward by the adjusting plate 17, and the first gear 20 and the second gear 21 are driven downward by the connecting shaft 19. At this time, the first gear 20 is engaged with the first rack 22, and the second gear 21 is disengaged from the second rack 24. The connecting shaft 19 is driven to rotate by the second motor 18, and the first gear 20 is driven to rotate by the connecting shaft 19. The first rack 22 is driven to move by the first gear 20, and the first guide plate 23 is driven to move by the first rack 22, so that the two first guide plates 23 clamp the lithium battery for preliminary correction, and then The first guide plate 23 performs the reset work, and drives the connecting shaft 19 to move upward through the adjusting plate 17, so that the second gear 21 is meshed with the second rack 24, and the second rack 24 is moved by the second gear 21, and the second guide plate 25 is moved by the second rack 24, and the rotating plate 26 is driven by the second guide plate 25 to clamp the lithium battery, and the rotating plate 26 is driven to rotate by the third motor 27, and the lithium battery is driven to rotate by the rotating plate 26, so that the electrodes of the lithium battery are set upward. When the electrodes of the lithium battery are placed upward, the connecting shaft 19 is directly driven by the adjusting plate 17 to switch from bottom to top, and the lithium battery is guided. Finally, the lithium battery is driven to rotate by the disc 7 so that the electrodes of the lithium battery are toward the first conveyor 2 to complete the lithium battery guidance work, thereby realizing the problem of guiding the lithium battery in any state.

[0093] As an optional embodiment, the detection component includes:

[0094] A rectangular through hole 28 is provided on the detection platform 1;

[0095] A first support plate 29 is provided at the bottom of the rectangular through hole 28, and one end of the first support plate 29 close to the mounting platform 3 is fixedly connected to the bottom of the detection platform 1 through an extension plate 30, and the other end is fixedly connected to the bottom of the detection platform 1 through two connecting rods 31;

[0096] A first mounting plate 32 is provided on top of the rectangular through hole 28. Support rods 33 passing through the rectangular through hole 28 are provided at the four corners of the bottom of the first mounting plate 32. Both ends of each support rod 33 are fixedly connected to the first mounting plate 32 and the first support plate 29 respectively.

[0097] An internal resistance tester 34 is provided on top of the first mounting plate 32;

[0098] A storage plate 35 is provided at the bottom of the first mounting plate 32, and the four corners of the storage plate 35 are respectively mounted on the support rods 33;

[0099] A second mounting plate 36 is provided on top of the storage plate 35. Two detection rods 37 for use with lithium batteries are fixedly provided at the bottom of the second mounting plate 36. Each detection rod 37 is electrically connected to a connection line of the internal resistance tester 34.

[0100] The linkage assembly is arranged on the top of the first mounting plate 32. The two ends of the linkage assembly are respectively connected to the storage plate 35 and the second mounting plate 36. The linkage assembly moves downward through the storage plate 35, causing the second mounting plate 36 to move downward.

[0101] For example, the lithium battery is transported to the storage plate 35 by the first conveyor 2, and the gravity of the lithium battery drives the storage plate 35 to move downward, and the storage plate 35 drives the linkage component to work, and the linkage component drives the second mounting plate 36 to move downward, and the second mounting plate 36 drives the detection rod 37 to move downward. When the storage plate 35 falls onto the first support plate 29, the detection rod 37 just contacts the electrode of the lithium battery, and the internal resistance tester 34 is used to detect the capacity loss inside the lithium battery, and the subsequent processing of the lithium battery is determined according to the test results, thereby realizing the detection and processing problem of the lithium battery.

[0102] As an optional embodiment, a baffle 38 is provided on the side of the storage plate 35 away from the first conveyor 2, the baffle 38 is fixedly connected to the inspection platform 1, and two limit plates 39 are provided on the top of the storage plate 35 for preventing the lithium battery from shifting.

[0103] For example, by setting a baffle 38, when the lithium battery moves from the first conveyor 2 to the storage plate 35, it will not exceed the storage plate 35 due to inertia, resulting in the detection rod 37 being unable to contact the electrode. By setting a limit plate 39 on the storage plate 35, the lithium battery will not be offset due to friction, resulting in the detection rod 37 being unable to contact the electrode, thereby achieving the problem of limiting control of the lithium battery when it moves to the storage plate 35.

[0104] As an optional embodiment, a first cylinder 40 is mounted on the side of the extension plate 30 close to the mounting platform 3, and a telescopic rod of the first cylinder 40 passes through the extension plate 30 and is fixedly connected to a first push plate 41. A second conveyor 42 is provided on the side of the first support plate 29 away from the extension plate 30, and a downwardly tilted material receiving frame 43 is provided next to the second conveyor 42. One side of the material receiving frame 43 is connected to the second conveyor 42, and a second cylinder 44 is mounted on the side of the second conveyor 42 away from the material receiving frame 43, and a second push plate 45 is fixedly connected to the telescopic rod of the second cylinder 44.

[0105] For example, when the inspection is completed, the first push plate 41 is driven to move by the first cylinder 40, and the lithium battery is moved to the second conveyor 42 by the first push plate 41. According to the inspection result, when the lithium battery moves to the position of the material receiving frame 43, whether to stop the second conveyor 42 is determined. The second push plate 45 is driven to move by the second cylinder 44, and the lithium battery is moved into the material receiving frame 43 by the second push plate 45. When the internal battery of the lithium battery is seriously damaged, it is sent to the material receiving frame 43 for complete replacement of the internal battery. When the internal battery of the lithium battery is not damaged much, the second conveyor 42 does not stop and is directly transported to the next process for partial battery replacement, thereby realizing the problem of classified processing of the lithium battery inspection results.

[0106] As an optional embodiment, the linkage component includes:
