The clamping fixtures 17 on the lower chamber module 12 are used to fix the battery to be tested. The first transfer rack 10 can be provided with a clamping fixture 17, which is used to clamp unqualified batteries; the clamping fixtures 17 on the second transfer rack 20 and the matching mechanism 16 are all used to clamp qualified batteries. The horizontal loading and clamping assembly 13, the horizontal unloading and clamping assembly 14, and the horizontal unloading and clamping assembly 15 all include a sliding module and a lifting manipulator; the sliding module of the horizontal loading and clamping assembly 13 moves back and forth laterally along the guide rail bracket 21 (with a lifting manipulator); Figure 1 The lifting manipulator moves back and forth left and right, and finally clamps the battery to be tested on the left side and places it on the clamping fixture 17 on the lower chamber module 12 by loosening and tightening, completing the loading of the battery to be tested.

[0062] A method for detecting the full welding seal of a blade battery top cover, the method comprising the following steps:

[0063] Step S1: placing the battery to be tested in the testing box 1, and evacuating several sealed cavities in the testing box 1 to a specified pressure through the vacuum pumping mechanism 2;

[0064] Step S2: Determine whether there are any batteries that failed the first round according to the vacuum pumping mechanism 2. If yes, execute step S3; if no, execute step S4.

[0065] Step S3: vacuumizing each sealed cavity one by one to a specified pressure through the vacuuming mechanism 2, screening out the first round of unqualified batteries, and obtaining the first round of qualified batteries;

[0066] Step S4: vacuuming the corresponding first-round qualified batteries to a specified pressure through each helium detection module 4 and then injecting helium, and each sealed cavity is connected to the helium detector 3 through the first pipeline for detection;

[0067] Step S5: judging whether there are any unqualified batteries in the second round according to the helium detector 3, if yes, executing step S6, if no, outputting the final qualified batteries;

[0068] Step S6: Each first-round qualified battery in the test box 1 is exhausted one by one by the helium detection module 4 and evacuated to a specified pressure, and then helium is injected. The helium detector 3 re-checks the helium in each sealed cavity one by one to screen out the second-round unqualified batteries and obtain the final qualified batteries.

[0069] Furthermore, in step S2, if it is determined that there are unsatisfactory batteries in the first round, step S3 is executed, and at the same time, another vacuum pumping mechanism 2, another helium detector 3, and the helium detection module 4 of the next detection box 1 make judgments according to steps S1-S6 on the next detection box 1 with the battery to be tested. Preferably, each sealed cavity can be vacuumed before executing step S6.

[0070] Furthermore, in step S5, if it is determined that there are batteries that fail the second round, step S6 is executed. At the same time, another vacuum pumping mechanism 2, another helium detector 3 and the helium detection module 4 of the next detection box 1 judge the next detection box 1 with the battery to be tested according to steps S1-S6.

[0071] Furthermore, in step S2, the vacuum pumping mechanism 2 determines whether there are any batteries that fail the first round according to the pressure difference between the inside and outside of the battery to be tested.

[0072] Furthermore, in step S5, the helium detector 3 determines whether there are any failed batteries in the second round according to whether there is helium leakage outside the battery to be tested.

[0073] The vacuum pumping mechanism 2 of the utility model can be selected as a vacuum pump. Specifically, in the present embodiment, each vacuum pumping mechanism 2 can be selected to be composed of a large vacuum pump and a small vacuum pump. The large vacuum pump is used to evacuate the sealed cavity, and the small vacuum pump can be used to evacuate the battery. Among them, through the pipeline arrangement, all the second switch valves can be opened, and multiple sealed cavities are connected to the second conduit 9. The vacuum pumping mechanism 2 can evacuate multiple sealed cavities in a single detection box 1 to a specified pressure (such as any value selected from 30 to 100 Pa) at the same time in step S1. That is, in the present embodiment, the second switch valve on the second conduit 9 controls the opening and closing of a single sealed cavity, and can also check a single sealed cavity one by one. The pumping speed of the large vacuum pump ≥ 60m 3 / h, ultimate vacuum degree ≤5Pa; small vacuum pump is used for battery vacuuming, pumping speed ≥15m 3 / h, the ultimate vacuum degree ≤5Pa; the above data is for reference only. The helium detection module 4 can select a helium injection cylinder, and each helium detection module 4 can simultaneously evacuate the corresponding battery to be tested in the opened sealed cavity to a specified pressure, and the relative pressure can be selected as -80Kpa. Specifically, the helium detection module 4 can also be provided with a corresponding solenoid valve to control its opening and closing. The helium detection module 4 can also inject helium into the corresponding battery to be tested. The helium detector 3 can detect whether there is helium leakage in the multiple sealed cavities in a single detection box 1 through the first conduit 22, so as to determine whether there are unqualified battery products. Similarly, that is, in this embodiment, the opening and closing of a single sealed cavity is controlled by the first switch valve on the first conduit 22, and a single sealed cavity can be inspected one by one, which is similar to the above-mentioned vacuuming. All the first switch valves can also be opened, and multiple sealed cavities are connected to the first conduit 22. Due to the attachment of the first conduit 22 in the device Figure 1 On the inside, so Figure 2 One end of the first conduit 22 can be shown, as Figure 4 The hole on the top of the middle detection box 1 is a connection hole for connecting the first conduit 22, and the first conduit 22 is connected to the connection hole to communicate with the sealed cavity. The helium detection module 4 may include a helium injection cylinder, a helium injection nozzle, an M5 connector, and the like.

[0074] The code scanning mechanism 19 is used to identify the battery to be tested so as to further screen the battery to be tested.

[0075] The present application includes a loading assembly, a vacuum test, a helium test, and a transfer unloading mechanism, which can efficiently load materials, quickly test batteries, and classify unloading materials to ensure the stability of product quality, fast testing process, and high overall efficiency. The helium detection module 4 can evacuate the corresponding sealed cavity and inject helium into the corresponding battery to be tested; the loading assembly can place the battery to be tested in the sealed cavity in the test box 1, and the test box 1 is formed by matching the lower cavity module 12 with the upper cavity module 11, which can accurately match the seal. The whole process has a high degree of automation and high work efficiency. Furthermore, the upper cavity module 11 can be provided with a positioning sensor to accurately detect the position of the lower cavity module 12 to ensure accurate matching. As can be seen in the attached figure, there is no symbol.

It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principle of the utility model, and these improvements and modifications are also regarded as the protection scope of the utility model.
