The two-dimensional code records the relevant data information of the battery cells 7, which is convenient for realizing data traceability of the battery cells 7.

[0022] Specifically, as Figures 1 - 5 As shown, in this embodiment, the tray 2 includes: a plate body 21, multiple positioning pin holes, and multiple fixing components; the multiple fixing components are arranged on the top surface of the plate body 21, arranged in a column along the length direction of the plate body 21, the multiple fixing components are located on the same straight line, and the multiple fixing components respectively fix the multiple battery cells 7 one by one; the multiple positioning pin holes are opened on the bottom surface of the plate body 21 and cooperate with the tray precise positioning module 3 to perform precise positioning on the plate body 21. The positioning pin holes are blind holes. Suspension rings 22 are also fixed at both ends of the top surface of the plate body 21, which is convenient for handling and moving.

[0023] Furthermore, as Figures 1 - 5As shown, in this embodiment, the fixing component includes: a bottom plate 23 and a pair of fixing plates 24; the bottom plate 23 and the pair of fixing plates 24 are fixed on the plate body 21, the bottom plate 23 is arranged between the pair of fixing plates 24, and the pair of fixing plates 24 are arranged oppositely; the bottom plate 23 supports the battery cell 7, and the pair of fixing plates 24 define the position of the battery cell 7; the top end of the fixing plate 24 is provided with a slope, which facilitates the smooth insertion and removal of the battery cell 7 between the pair of fixing plates 24. The fixing plate 24 is U-shaped, the U-shaped opening faces the battery cell 7, and both sides of the fixing plate 24 are connected to both sides of the battery cell 7 to define the battery cell 7.

[0024] Further, as Figures 1 - 5 shown, in this embodiment, the tray fine positioning module 3 includes: a cylinder mounting plate 31, a lifting cylinder 32, a lifting plate 33, a plurality of positioning pins 34, a plurality of guide posts 35 and a detection component; the cylinder mounting plate 31 is fixed on the frame 1; the cylinder is mounted on the cylinder mounting plate 31, and the output end of the cylinder penetrates through the cylinder mounting plate 31 and is connected to the bottom surface of the lifting plate 33; a plurality of positioning pins 34 are fixed on the top surface of the lifting plate 33 and correspond to a plurality of positioning pin holes one by one; a plurality of guide posts 35 penetrate through the cylinder mounting plate 31 and are connected to the top surface of the lifting plate 33, and the plurality of guide posts 35 are slidably connected to the cylinder mounting plate 31; the lifting cylinder 32 lifts the lifting plate 33, driving the plurality of positioning pins 34 to be inserted into the plurality of positioning pin holes respectively to perform fine positioning on the tray 2. The detection component is arranged on the cylinder mounting plate 31 and the lifting plate 33 to detect whether the tray 2 is in place, including whether the external conveyor line conveys the tray 2 in place and whether the tray 2 is lifted in place. The detection component facilitates triggering the action of the lifting cylinder 32.

[0025] Further, as Figures 1 - 5 shown, in this embodiment, the detection component includes: a in-place sensor 36, a high-position sensor 37 and a low-position sensor 38; the in-place sensor 36 is fixed on the top surface of the lifting plate 33 to detect the presence or absence of the tray 2. When the in-place sensor 36 detects the tray 2, it triggers the lifting cylinder 32 to perform a lifting action; the high-position sensor 37 and the low-position sensor 38 are fixed on the cylinder mounting plate 31 through a fixing bracket 39. The high-position sensor 37 is arranged above the low-position sensor 38. The high-position sensor 37 and the low-position sensor 38 determine the position of the tray 2 according to the presence or absence of the detection signal. The high-position sensor 37 and the low-position sensor 38 are opposite to the lifting plate 33; when the high-position sensor 37 detects a signal while the low-position sensor 38 does not detect it, it means that the lifting plate 33 has moved to the target high position, then the tray 2 is lifted in place and the lifting cylinder 32 stops lifting; when the low-position sensor 38 detects a signal while the high-position sensor 37 does not detect it, it means that the lifting plate 33 has moved to the target low position, then the positioning pins 34 are disengaged from the positioning pin holes of the tray 2, and the lifting cylinder 32 stops descending.

[0026] Specifically, as Figures 1 - 5As shown in the figure, in this embodiment, the driving module 4 includes: a pair of guide rails 41, a mounting bracket 42, and a downward pressing cylinder 43; the pair of guide rails 41 are vertically fixed on the frame 1; the mounting bracket 42 is slidably arranged on the pair of guide rails 41, and the pair of guide rails 41 guide the mounting bracket 42. A plurality of test modules 6 and a code scanning module 5 are fixed on the mounting bracket 42; the downward pressing cylinder 43 is fixed on the frame 1, and the output end of the downward pressing cylinder 43 is connected to the mounting bracket 42. The downward pressing cylinder 43 drives the mounting bracket 42 to slide along the guide rail 41, driving the plurality of test modules 6 and the code scanning module 5 to approach or move away from the test station. After the pallet 2 is positioned, the downward pressing cylinder 43 drives the mounting bracket 42 to move down in place, so that the plurality of test modules 6 are respectively connected to the tabs of the plurality of battery cells 7 for OCV testing. At the same time, the code scanning module 5 scans and binds the two-dimensional code on the battery cell 7; after the testing and code scanning are completed, the downward pressing cylinder 43 drives the mounting bracket 42, the plurality of test modules 6 and the code scanning module 5 to move up as a whole, disengaging from the battery cell 7 and the pallet 2, facilitating the battery cell 7 and the pallet 2 to flow into the next station.

[0027] Further, as Figures 1 - 5 shown, in this embodiment, an installation block 44 is further provided below each guide rail 41. The installation block 44 is fixed on the frame 1, and a downward pressing sensor 45 and a buffer 46 are fixed on the installation block 44. The downward pressing sensor 45 detects whether the mounting bracket 42 has moved in place. When the mounting bracket 42 touches the downward pressing sensor 45, the downward pressing cylinder 43 is triggered to stop descending. The buffer 46 is used for buffering the mounting bracket 42.

[0028] Specifically, as Figures 1 - 5 shown, in this embodiment, the test module 6 includes: a U-shaped mounting plate 61 and a pair of test probes 62; the U-shaped mounting plate 61 is fixed on the driving module 4, and the opening of the U-shaped mounting plate 61 faces away from the driving module 4; the pair of test probes 62 are respectively fixed at both ends of the U-shaped mounting plate 61 and are used to connect the positive and negative tabs of the battery cell 7 for OCV testing. The opening of the U-shaped mounting plate 61 exposes the two-dimensional code on the battery cell 7, facilitating the code scanning gun of the code scanning module 5 to scan and bind.

[0029] Specifically, as Figures 1 - 5As shown in the figure, in this embodiment, the code scanning module 5 includes: a slide rail 51, a plurality of code scanners 52, a moving cylinder 53, and a bracket 54; the slide rail 51 and the moving cylinder 53 are fixed on the driving module 4; the bracket 54 is slidably arranged on the slide rail 51 and is connected to the output end of the moving cylinder 53, and a plurality of code scanners 52 are evenly and spacedly fixed on the bracket 54; the moving cylinder 53 drives the bracket 54 to move along the slide rail 51, driving the plurality of code scanners 52 to move, so as to scan the two-dimensional codes of a plurality of battery cells 7. The number of the test modules 6 is the same as the number of the battery cells 7 and the number of the fixing components on the plate body 21, and they are both twice the number of the code scanners 52. After the code scanners 52 complete the scanning at the first position, the moving cylinder 53 and the slide rail 51 drive the code scanners 52 to move to the second position for scanning, realizing the scanning and binding of all the battery cells 7, which can save half of the code scanners 52 and greatly reduce the cost.

[0030] Working principle: The tray 2 is conveyed to the test station through an external conveyor line. After the in-place sensor 36 detects the tray 2, when the tray 2 lifting cylinder 32 lifts the lifting plate 33, the positioning pin 34 enters the positioning pin hole of the tray 2, and the high-level sensor 37 detects the signal.

[0031] The pressing cylinder 43 extends, and the mounting frame 42 drives the plurality of test modules 6 and the code scanning module 5 to descend along the guide rail 41. When the mounting frame 42 touches the pressing sensor 45 and the buffer 46, it stops descending. The test probe 62 presses down for OCV testing, and at the same time the code scanner 52 performs code scanning at the first position. After the code scanning at the first position is completed, the moving cylinder 53 pulls back, and the code scanner 52 performs code scanning at the second position (taking the number of battery cells 7 as 6 as an example, each test device saves 3 automatic code scanners 52, so the entire tooling saves 6 code scanners 52). After the code scanning is completed, the battery cell codes are uploaded in sequence.

[0032] After the OCV test is completed, the pressing cylinder 43 retracts, and the mounting frame 42 drives the plurality of test modules 6 and the code scanning module 5 to rise along the guide rail 41. The test probe 62 leaves the battery cell 7 and reaches a safe distance. After the OCV test is completed, the test results of different battery cells 7 will be bound to the two-dimensional codes of the corresponding battery cells 7 and uploaded to the factory MES.

[0033] The lifting cylinder 32 descends. The high-level sensor 37 does not detect the signal, and the low-level sensor 38 detects the signal. Then the positioning pin 34 disengages from the positioning pin hole and reaches the set safe distance, and the lifting cylinder 32 stops operating. The tray 2 flows into the next station.

[0034] The above is for reference Figures 1 - 5Describes a double-station high-beat OCV code scanning test tooling according to an embodiment of the present invention, which can avoid the risk of incorrect manual feeding. The cell testing and cell code scanning are carried out simultaneously to save the station time, greatly improve the production beat, precisely position the tray to improve the equipment matching accuracy, and avoid damage to the cell when the test probe presses down. Two sets of test equipment operate independently at the same time, which not only ensures the test time but also greatly improves the station beat and increases the production capacity.
