Description

Technical Field

[0001] This invention relates to the field of lithium battery technology, and in particular to an automatic online detection and automatic warehousing device and method for waste batteries. Background Technology

[0002] After meeting the required settling time in the ambient temperature storage room, lithium batteries are transported via conveyor line to OCV and DCIR testing devices for OCV and DCIR testing, respectively. OCV testing yields parameters such as the K-value, current, voltage, and capacity of the lithium batteries, allowing for the sorting of batteries with substandard electrochemical parameters to ensure the quality of the finished product. DC internal resistance (DCIR) is a crucial parameter for evaluating lithium battery performance (including charging DCCR and discharging DCCR).

[0003] Lithium batteries that meet the process requirements after OCV and DCIR testing directly enter the subsequent grading and coating process. Lithium batteries that do not meet the process requirements require secondary OCV and DCIR testing. The OCV and DCIR testing devices can automatically locate the position and quantity of lithium batteries that failed the first test on the tray and upload the information to the MES system. The MES system controls a three-axis robot to remove the lithium batteries that failed the first test from the tray, and then the tray is manually rotated and manually tested a second time. Lithium batteries that pass the second test need to be reloaded onto the tray, and then the QR codes on the lithium batteries and the tray are scanned manually and uploaded to the MES system for information binding before being reloaded into the subsequent grading and coating process. Lithium batteries that fail the second test need to be reloaded onto the tray and then manually transferred to the line-side buffer for storage. This manual tray loading and testing method is time-consuming and has low lithium battery testing efficiency. Summary of the Invention

[0004] Based on this, and addressing the technical problems existing in the current technology, the purpose of this invention is to provide an automatic online testing and storage device and method for waste batteries. This device automatically assembles lithium batteries that fail the first OCV and / or first DCIR tests into trays, and automatically transports lithium batteries that fail the first OCV and / or first DCIR tests to the OCV and DCIR testing devices for secondary testing. It also automatically assembles lithium batteries that fail the second OCV and / or second DCIR tests into trays, and automatically stores trays fully loaded with lithium batteries that fail the second OCV and / or second DCIR tests. This improves the efficiency of lithium battery testing, reduces the time spent on manual tray loading and testing, improves the efficiency of the entire production line's transfer process, saves space in the construction of line-side warehouses, and reduces the labor intensity of workers.

[0033] This invention also proposes an automatic online detection and automatic warehousing method for waste batteries, which uses the aforementioned automatic online detection and automatic warehousing equipment for waste batteries, and includes the following steps:

[0034] S1. In the initial state, both the first and second pallet buffer conveyors are equipped with empty pallets. Conveyor line 1 conveys the pallet containing the settled lithium batteries to the OCV detection device and the DCIR detection device. The OCV detection device and the DCIR detection device perform an OCV detection and a DCIR detection on the lithium batteries on the pallet in sequence. If there are lithium batteries on the pallet that fail one OCV detection and / or one DCIR detection, the conveyor line 1 conveys the pallet to the waste transfer unit.

[0035] S2. The waste transfer unit transfers the pallet containing lithium batteries that have passed one OCV test and one DCIR test on conveyor line 1 to the waste discharge buffer conveyor. The three-axis robot transfers the lithium batteries that failed one OCV test and / or one DCIR test on the pallet to the empty pallet on the pallet buffer conveyor and counts the lithium batteries that failed one OCV test and / or one DCIR test on the empty pallet. Then, the waste transfer unit transfers the pallet containing lithium batteries that passed one OCV test and one DCIR test on the waste discharge buffer conveyor to conveyor line 1. The coating robot picks up the lithium batteries that passed one OCV test and one DCIR test on the pallet. The transfer unit transfers the empty pallet on conveyor line 1 to the stacker crane. The stacker crane stores the empty pallet in the automated warehouse.

[0036] S3. When the number of lithium batteries on the tray transferred to the first pallet buffer conveyor by the three-axis robot reaches M, the first pallet buffer conveyor ...

[0037] S4. The waste transfer unit transfers the tray containing lithium batteries that have undergone secondary OCV and secondary DCIR testing from conveyor line one to the waste discharge buffer conveyor table; the three-axis robot transfers the lithium batteries that failed the secondary OCV and / or secondary DCIR testing from the tray to the empty tray of the tray buffer conveyor table two and counts the lithium batteries that failed the secondary OCV and / or secondary DCIR testing transferred to the empty tray; then, the waste transfer unit transfers the tray containing lithium batteries that passed the secondary OCV and secondary DCIR testing from the waste discharge buffer conveyor table to conveyor line one, and conveyor line one conveys the tray to the coating robot;

[0038] S5. When the number of lithium batteries on the tray transferred to the tray buffer conveyor two by the three-axis robot reaches N, the tray buffer conveyor two will transport the tray to the tray transfer component two, which will then transfer the tray to the conveyor line one. The transfer component will then transfer the tray to the stacker crane, which will store the tray containing lithium batteries that failed the secondary OCV test and / or secondary DCIR test in the automated warehouse. Here, N is an integer not less than 2.

[0039] Compared with the prior art, the present invention has the following beneficial effects:

[0040] This invention, through the installation of a waste discharge transfer unit, a waste discharge buffer conveyor, and a first palletizing buffer conveyor, enables a three-axis robot to automatically palletize lithium batteries that failed the first OCV and / or first DCIR tests. The first palletizing transfer unit and a transfer component automatically transport these batteries to the OCV and DCIR testing devices for secondary testing. The second waste discharge transfer unit, waste discharge buffer conveyor, and a second palletizing buffer conveyor enable a three-axis robot to automatically palletize lithium batteries that failed the second OCV and / or second DCIR tests. The second palletizing transfer unit, the transfer component, and a stacker crane automatically store the pallets fully loaded with these batteries into an automated storage and retrieval system. This improves the efficiency of lithium battery testing, reduces the time spent on manual palletizing and testing, increases the efficiency of the entire production line's transfer process, saves space in the construction of a line-side warehouse, and reduces the labor intensity of workers.

[0041] This invention enables the automatic storage of empty pallets in an automated warehouse through the use of transfer components and stacker cranes. It also enables the automatic pallet replenishment of pallet assembly buffer conveyor platform one and pallet assembly buffer conveyor platform two. Attached Figure Description

[0051] Reference Figure 1This embodiment proposes an automated online detection and warehousing equipment for waste batteries, including a conveyor line 1, an OCV detection device 2, a DCIR detection device 3, a three-axis robot 4, a coating robot, a waste transfer unit 5, a barcode scanner 6, a waste buffer conveyor 7, a tray transfer unit 8, a barcode scanner 9, a tray buffer conveyor 10, a tray transfer unit 2, a barcode scanner 3, a tray buffer conveyor 2, a transfer unit 13, a transfer unit 14, a stacker crane 15, and an automated warehouse 16; it may also include a lifting and positioning mechanism 17, a lifting and stopping mechanism 4 18, a lifting and transplanting mechanism 6 19, a lifting and stopping mechanism 5 20, and a lifting and transplanting mechanism 7. 21. The lifting and stopping mechanism VI and the back-end controller, conveyor line 1, OCV detection device 2, DCIR detection device 3, three-axis robot 4, rubber coating robot, waste discharge transfer component 5, barcode scanner VI, waste discharge buffer conveyor 7, pallet transfer component VI, barcode scanner VII, pallet buffer conveyor VI, pallet transfer component VII, barcode scanner VII, pallet buffer conveyor VI, barcode scanner VII, pallet buffer conveyor VI, transfer component VII, stacker crane VII, lifting and positioning mechanism VI, lifting and stopping mechanism VII, lifting and transplanting mechanism VI, lifting and stopping mechanism VII, lifting and transplanting mechanism VII, lifting and stopping mechanism VI, and lifting and stopping mechanism VI VII are all connected to the back-end controller.

[0052] Conveyor line 1 is used for transporting pallets. Along the conveying direction of conveyor line 1, there are sequentially arranged inbound, outbound, OCV inspection, DCIR inspection, waste removal, pallet assembly station 1, pallet assembly station 2, and coating positioning station. Outbound conveyor line 23 connects to the outbound station of conveyor line 1. Outbound conveyor line 23 transports pallets containing lithium batteries that have been placed in a room-temperature settling chamber. Outbound conveyor line 23 is controlled by a back-end controller to transport the pallets to conveyor line 1. A barcode scanner 24 is also installed at the outbound station to scan and identify the QR codes on the pallets. The barcode scanner 24 uses an existing barcode scanner, which is fixed at the outbound station and can identify the QR code information on the pallets. Further details are omitted here. Conveyor line 1, controlled by the back-end controller, then transports the pallets to the OCV inspection station, DCIR inspection station, waste removal station, pallet assembly station 1, pallet assembly station 2, or coating positioning station. In this embodiment, the conveyor line 1 adopts the existing roller conveyor line, which will not be described in detail here.

[0053] OCV testing device 2 and DCIR testing device 3 are respectively installed at the OCV testing station and the DCIR testing station, located on one side of conveyor line 1. OCV testing device 2 and DCIR testing device 3 can perform OCV and DCIR tests on the lithium batteries on the tray, automatically locate the lithium batteries on the tray that fail the OCV and DCIR tests, and upload the test results to the backend controller. In this embodiment, both OCV testing device 2 and DCIR testing device 3 use existing mature equipment, which will not be described in detail here.

[0054] Both the lifting and transferring mechanism 619 and the lifting and stopping mechanism 520 are located at the OCV inspection station, with the lifting and transferring mechanism 619 positioned upstream of the lifting and stopping mechanism 520. When the lifting and stopping mechanism 520 lifts, it stops the pallet on conveyor line 1 on the lifting and transferring mechanism 619. The lifting and transferring mechanism 619 then transfers the pallet to the OCV inspection device 2. After the OCV inspection device 2 completes its inspection of the lithium battery on the pallet, it transfers the pallet back to the lifting and transferring mechanism 619, which is still in the lifting state. Then, both the lifting and transferring mechanism 619 and the lifting and stopping mechanism 520 descend and reset, and the pallet continues to be conveyed forward by conveyor line 1. In this embodiment, the lifting and transplanting mechanism 619 adopts existing lifting and transplanting equipment, which includes a lifting cylinder, a lifting plate, and two belt conveyor mechanisms. The lifting cylinder is located below conveyor line 1, and the lifting plate is fixed to the top of the piston rod of the lifting cylinder. Both belt conveyor mechanisms are mounted on the lifting plate for driving the transfer. The two belt conveyor mechanisms are parallel to each other and have the same conveying surface height. The conveying direction of both belt conveyor mechanisms is perpendicular to the conveying direction of conveyor line 1. When the lifting cylinder drives the lifting plate to lift, each belt conveyor mechanism passes between two adjacent conveying rollers of conveyor line 1. In this embodiment, the lifting and stopping mechanism 520 adopts a vertically arranged lifting baffle in the prior art: when the lifting baffle rises to stop the lifting, it passes between two adjacent conveying rollers of conveyor line 1, blocking the battery cell trays on conveyor line 1 from continuing to be conveyed forward; when the lifting baffle falls downward, its top surface drops below the conveying surface of conveyor line 1, at which point the battery cell trays on conveyor line 1 can continue to be conveyed forward.

[0055] Both the lifting and transplanting mechanism 721 and the lifting and stopping mechanism 622 are located at the OCV inspection station, with the lifting and transplanting mechanism 721 upstream of the lifting and stopping mechanism 622. When the lifting and stopping mechanism 622 lifts, it stops the tray on conveyor line 1 on the lifting and transplanting mechanism 721. The lifting and transplanting mechanism 721 then transfers the tray to the OCV inspection device 2. After the OCV inspection device 2 completes its inspection of the lithium battery on the tray, it transfers the tray to the lifting and transplanting mechanism 721, which is in a lifted state. Then, both the lifting and transplanting mechanism 721 and the lifting and stopping mechanism 622 descend and reset, and the tray continues to be conveyed forward by conveyor line 1. In this embodiment, the lifting and transplanting mechanism 721 uses the existing lifting and transplanting equipment described above, and the lifting and stopping mechanism 622 uses the existing vertically arranged lifting baffle as described above; further details are omitted here.

The conveying direction of the second lifting and transplanting mechanism 801 is perpendicular to the conveying direction of conveyor line 1 and opposite to the conveying direction of the tray assembly buffer conveyor platform 10. When the second lifting and transplanting mechanism 801 lifts, it transfers the trays on it to the tray assembly buffer conveyor platform 10 or receives trays from the tray assembly buffer conveyor platform 10. In this embodiment, the second lifting and transplanting mechanism 801 adopts the existing lifting and transplanting equipment as described above, and the second lifting and stopping mechanism 802 adopts the existing vertically arranged lifting baffle as described above, which will not be elaborated further here.

[0059] The three-axis robot 4 is located on one side of conveyor line 1. The three-axis robot 4 is used to transfer lithium batteries that fail the first OCV test and / or the first DCIR test on the tray of the waste discharge buffer conveyor 7 to the tray of the assembly buffer conveyor 10. It is also used to transfer lithium batteries that fail the second OCV test and / or the second DCIR test on the tray of the waste discharge buffer conveyor 7 to the tray of the assembly buffer conveyor 13. At the same time, the three-axis robot 4 can also count the transferred lithium batteries.

[0060] A coating robot (not shown), a lifting and positioning mechanism 17, and a lifting and stopping mechanism 4 18 are all installed at the coating positioning station. The coating robot is located on one side of conveyor line 1. The lifting and positioning mechanism 17 and the lifting and stopping mechanism 4 18 are both installed on conveyor line 1, with the lifting and stopping mechanism 4 18 located downstream of the lifting and positioning mechanism 17. When a tray carrying lithium batteries that have passed OCV and DCIR testing is transported to the coating positioning station, the lifting and stopping mechanism 4 18 lifts upwards, stopping the tray on the lifting and positioning mechanism 17. The lifting and positioning mechanism 17 then lifts upwards, and the coating robot picks up the lithium batteries that have passed OCV and DCIR testing from the tray on the lifting and positioning mechanism 17 for coating. After the lithium batteries that have passed OCV and DCIR testing on the tray have been picked up, the lifting and positioning mechanism 17 and the lifting and stopping mechanism 4 18 both descend to their original positions. The lifting and positioning mechanism 17 then transports the empty tray to conveyor line 1, which then transports the empty tray forward. In this embodiment, the lifting and stopping mechanism 18 adopts the vertically arranged lifting baffle as described above in the prior art, which will not be elaborated here; while the lifting and positioning mechanism 17 adopts the lifting and positioning device in the prior art. The lifting and positioning device includes a lifting cylinder, a positioning plate and a conveying roller group. The lifting cylinder is located below the conveyor line 1. The positioning plate is fixed to the top of the piston rod of the lifting cylinder. When the lifting cylinder drives the positioning plate to lift, the positioning plate passes between two adjacent conveying rollers of the conveyor line 1. The conveying roller group is set on the positioning plate for conveying. The conveying direction of the conveying roller group is consistent with the conveying direction of the conveyor line 1.

It is also used to transfer empty pallets and pallets carrying lithium batteries that have failed two OCV tests and / or two DCIR tests on conveyor line 1 to stacker crane 15. Stacker crane 15 stores the empty pallets and pallets carrying lithium batteries that have failed two OCV tests and / or two DCIR tests in the corresponding storage locations of the automated warehouse 16. In this embodiment, the transfer unit 14 includes an inter-layer lifting mechanism 1401, a second conveyor line (not shown), an inter-layer lifting mechanism 1402, an inbound conveyor line 1403, a lifting and transplanting mechanism 1405, a lifting and transplanting mechanism 1406, and an inbound machine 1404. The second conveyor line is located below conveyor line 1, and its conveying direction is opposite to that of conveyor line 1. Inter-layer lifting mechanism 1401 has its top end connected to the discharge end of conveyor line 1 and its bottom end connected to the feed end of conveyor line 2. Inter-layer lifting mechanism 1401 is used to lower and transport pallets from conveyor line 1 to conveyor line 2. Inter-layer lifting mechanism 1402 has its bottom end connected to the discharge end of conveyor line 2 and its top end connected to the warehousing station of conveyor line 1. Inter-layer lifting mechanism 1402 is used to lift pallets from conveyor line 2 to conveyor line 1. The feed end of warehousing conveyor line 1403 is connected to the warehousing station of conveyor line 1, and the conveying direction of warehousing conveyor line 1403 is perpendicular to the conveying direction of conveyor line 1. Lifting and transplanting mechanism four 1405 is installed on conveyor line one 1 and located at the warehousing station. When lifting and transplanting mechanism four 1405 is in the lifting state, the height of the conveying surface of lifting and transplanting mechanism four 1405 is the same as the height of the conveying surface of warehousing conveyor line 1403, and it transfers the pallets on it to warehousing conveyor line 1403. Lifting and transplanting mechanism five 1406 is installed at the discharge end of warehousing conveyor line 1403 and is used to transfer the pallets on warehousing conveyor line 1403 to warehousing machine 1404. Stacker crane 15 stores the pallets on warehousing machine 1404 into the corresponding storage positions of automated warehouse 16. In this embodiment, lifting and transplanting mechanism four 1405 and lifting and transplanting mechanism five 1406 both adopt existing lifting and transplanting equipment as described above, which will not be elaborated here.

[0062] It should be noted that in this embodiment, the pallet carries 6 lithium batteries when fully loaded. Of course, in other embodiments, the pallet can carry 4, 5, or 7 lithium batteries when fully loaded, as long as the transport stability is met and the lithium batteries are prevented from falling off due to overload.

[0063] Next, combined Figures 3-6 The working principle of this embodiment will be explained as follows:

[0064] (1) In the initial state, both the tray buffer conveyor 10 and the tray buffer conveyor 213 have empty trays. At the same time, the background controller controls the lifting stop mechanism 520 and the lifting stop mechanism 6 to lift upwards; Figure 3 As indicated by the upward arrow, the outbound conveyor line 23 transports a pallet fully loaded with lithium batteries that have been placed in a room temperature storage room. The pallet enters the outbound workstation onto the conveyor line 1. The barcode scanner 24 scans and identifies the pallet and sends the pallet information to the backend controller. The conveyor line 1 then transports the pallet forward.

[0065] (2) When the pallet is transported to the OCV testing station, the lifting stop mechanism 520 stops it on the lifting transfer mechanism 619; then the lifting transfer mechanism 619 lifts and transfers the pallet to the OCV testing device 2. The OCV testing device 2 performs an OCV test on the lithium battery on the pallet and determines whether the lithium battery is qualified, and sends the test result to the background controller; after the OCV test is completed, the OCV testing device 2 transfers the pallet to the lifting transfer mechanism 619, the lifting transfer mechanism 619 and the lifting stop mechanism 520 descend and reset, and the conveyor line 1 continues to transport the pallet forward; when When the pallet is transported to the DCIR testing station, it is stopped by the lifting and stopping mechanism 6 22 on the lifting and transferring mechanism 7 21. Then, the lifting and transferring mechanism 7 21 lifts and transfers the pallet to the DCIR testing device 3. The DCIR testing device 3 performs a DCIR test on the lithium battery on the pallet and determines whether the lithium battery is qualified, and sends the test result to the background controller. After the DCIR test is completed, the DCIR testing device 3 transfers the pallet to the lifting and transferring mechanism 7 21. The lifting and transferring mechanism 7 21 and the lifting and stopping mechanism 6 22 are lowered and reset, and the conveyor line 1 continues to transport the pallet forward.

[0066] (3) If the lithium batteries on the tray pass both the first OCV and the first DCIR tests, the back-end controller controls the lifting and stopping mechanism 18 to lift; when the tray is transported to the coating positioning station, the tray is stopped by the lifting and stopping mechanism 18 on the lifting and positioning mechanism 17, the lifting and positioning mechanism 17 lifts, and the coating robot grabs the lithium batteries on the tray that have passed both the first OCV and the first DCIR tests for coating; if Figure 4As indicated by the upward arrow conveying direction, after the lithium battery on the pallet is picked up, the lifting and positioning mechanism 17 and the lifting and stopping mechanism 18 descend and reset. Conveyor line 1 transports the empty pallet to its discharge end. Interlayer lifting mechanism 1401 transports the empty pallet to conveyor line 2. Conveyor line 2 then transports the empty pallet to interlayer lifting mechanism 2 1402. Interlayer lifting mechanism 2 1402 lifts the empty pallet to the storage station of conveyor line 11. Lifting and transferring mechanism 1405 lifts and transfers the empty pallet to the storage conveyor line 1403, and finally enters the storage machine 1404. The background controller controls the stacker crane 15 to store the empty pallet in the corresponding storage location of the automated warehouse 16 according to the pallet information.

[0067] (4) If there is a lithium battery on the tray that has failed one OCV and / or one DCIR test, the OCV detection device 2 and the DCIR detection device 3 will send the tray information to the backend controller and also send the location information of the lithium battery that failed the test to the backend controller; Figure 5 As indicated by the upward arrow conveying direction, when the barcode scanner 6 scans and identifies the tray containing the defective lithium batteries, the lifting and stopping mechanism 502 lifts and stops the tray on the lifting and transferring mechanism 501. The lifting and transferring mechanism 501 then lifts and transfers the tray to the waste discharge buffer conveyor 7. The three-axis robot 4, based on the information from the backend controller, grabs the lithium batteries that failed the first OCV and / or first DCIR test on the tray and transfers them to the empty tray on the tray buffer conveyor 10. At the same time, the three-axis robot 4 also records the number of lithium batteries that failed the first OCV and / or first DCIR test and transferred them.

[0068] (5) After the lithium batteries that failed one OCV and / or one DCIR test on the tray of the waste discharge buffer conveyor 7 are picked up, the waste discharge buffer conveyor 7 will transport the tray of lithium batteries that passed one OCV and one DCIR test to the lifting and transfer mechanism 501. The lifting and transfer mechanism 501 and the lifting stop mechanism 502 will be lowered and reset. The conveyor line 1 will continue to transport the tray to the coating and positioning station. The coating and positioning work of step (3) above will be repeated until the lithium batteries that passed one OCV and one DCIR test are picked up and coated and the empty tray is stored on the automated warehouse 16.

[0069] (6) Figure 5As indicated by the upward arrow indicating the conveying direction, when the three-axis robot 4 detects that the tray on the pallet buffer conveyor 10 is fully loaded, it sends information to the backend controller. The backend controller then controls the lifting and transferring mechanism 801 to lift the pallet. The pallet buffer conveyor 10, fully loaded with lithium batteries that failed one OCV and / or one DCIR test, conveys the pallet to the lifting and transferring mechanism 801. The lifting and transferring mechanism 801 then lowers and resets. The barcode scanner 9 scans and records the barcode on the pallet, and the conveyor line 1 transports the pallet. The inter-layer lifting mechanism 1401 transports the empty pallet to the second conveyor line, which then transports the empty pallet to the second inter-layer lifting mechanism 1402. The second inter-layer lifting mechanism 1402 lifts the empty pallet to the storage station of the first conveyor line, and the first conveyor line continues to transport it forward. Then the OCV and DCIR detection work of step (2) above is repeated to perform a second OCV and second DCIR detection on the lithium battery that fails the first OCV and / or first DCIR detection on the pallet.

[0070] (7) If the lithium battery on the tray passes the secondary OCV and secondary DCIR tests, repeat the above step (3) for the coating and positioning work until the lithium battery that has passed the secondary OCV and secondary DCIR tests is picked up and coated, and the empty tray is stored on the automated warehouse 16.

[0071] (8) If there are lithium batteries that fail the secondary OCV and / or secondary DCIR tests on the tray, the OCV detection device 2 and the DCIR detection device 3 send the tray information to the back-end controller and also send the location information of the lithium batteries that fail the secondary tests to the back-end controller; when the barcode scanner 6 scans and identifies the tray containing the lithium batteries that fail the secondary tests, the lifting and stopping mechanism 502 lifts and stops the tray on the lifting and transferring mechanism 501, and the lifting and transferring mechanism 501 lifts and transfers the tray to the waste discharge buffer conveyor 7; the three-axis robot 4 grabs the lithium batteries that fail the secondary OCV and / or secondary DCIR tests on the tray according to the information from the back-end controller and transfers them to the empty tray on the tray buffer conveyor 13. At the same time, the three-axis robot 4 also records the number of lithium batteries that fail the secondary OCV and / or secondary DCIR tests transferred.

[0072] (9) such as Figure 6As indicated by the upward arrow indicating the conveying direction, when the three-axis robot 4 detects that the tray on the pallet buffer conveyor 13 is fully loaded, it sends information to the backend controller. The backend controller then controls the lifting and transferring mechanism 1101 to lift the pallet. The pallet buffer conveyor 13, fully loaded with lithium batteries that failed the secondary OCV and / or secondary DCIR tests, is then conveyed to the lifting and transferring mechanism 1101. The lifting and transferring mechanism 1101 descends and resets. The barcode scanner 12 scans and records the barcode on the pallet. The conveyor line 1 then conveys the pallet to the inter-layer lifting mechanism 3. The inter-layer lifting mechanism 3 then removes the empty pallet. The pallet is conveyed to conveyor line two, which then conveys the empty pallet to inter-layer lifting mechanism two 1402. Inter-layer lifting mechanism two 1402 lifts the empty pallet to the storage station of conveyor line one 1. Lifting and transferring mechanism four 1405 lifts and transfers the pallet full of lithium batteries that have failed the secondary OCV and / or secondary DCIR tests to the storage conveyor line 1403, and finally enters the storage machine 1404. The back-end controller controls the stacker crane 15 to store the pallet full of lithium batteries that have failed the secondary OCV and / or secondary DCIR tests to the corresponding storage location in the automated warehouse 16 according to the pallet information.

[0073] It should be noted that when tray buffer conveyor 10 and tray buffer conveyor 2 13 are short of empty trays, combined with Figure 4 After the empty pallets generated by the above steps (3), (5) or (7), the inter-layer lifting mechanism 2 1402 lifts the empty pallets to the storage station of the conveyor line 1. The lifting and transplanting mechanism does not lift, and the conveyor line 1 continues to transport the empty pallets forward. The background controller controls the lifting and stopping mechanism 2 802 and the lifting and stopping mechanism 3 1102 to lift and stop. After the barcode scanner 2 9 and the barcode scanner 3 12 scan and identify the empty pallets at the corresponding positions, the lifting and transplanting mechanism 2 801 and the lifting and transplanting mechanism 3 1101 respectively transplant the empty pallets to the pallet grouping buffer conveyor platform 10 and the pallet grouping buffer conveyor platform 2 13 to replenish the pallets of the pallet grouping buffer conveyor platform 10 and the pallet grouping buffer conveyor platform 2 13.
