[0045] Reference Figure 1 , Figure 2 A battery test group comprising a test site 1, an X-axis test group 2, a Y-axis test group 3 and a Z-axis test group 4;

[0046] The test site 1 is used for placing the battery, the X-axis test group 2 is used for testing the battery along the X-axis direction of the test site 1, the Y-axis test group 3 is used for testing the battery along the Y-axis direction of the test site 1, and the Z-axis test group 4 is used for testing the battery along the Z-axis direction of the test site 1.

[0047] The X-axis test group 2, the Y-axis test group 3 or the Z-axis test group 4 is provided with a conductive part 211, which is used to contact the conductive part of the battery to test the insulation of the battery.

[0048] The X-axis test group 2, the Y-axis test group 3 and the Z-axis test group 4 are respectively used for testing the battery, which can accurately evaluate the pressure resistance and structural strength of the battery 7 along the X-axis, the Y-axis and the Z-axis, and ensure the stability of the detection result. The battery test group in the embodiment integrates the X-axis test group 2, the Y-axis test group 3, the Z-axis test group 4 and the insulation test into a mechanical unit for pressure and insulation test, which improves the detection efficiency and reduces the floor area of the mechanical unit.

[0049] Specifically, the conductive part 211 is a probe.

[0050] In an embodiment, the Y-axis test group 3 comprises a Y-axis reference positioning part 31, a Y-axis driving part 32, a second Y-axis pressing plate 33 and a Y-axis pressure sensor 34.

[0051] Along the Y-axis direction, the Y-axis reference positioning part 31 is arranged on one side of the test site 1, and the Y-axis driving part 32, the second Y-axis pressing plate 33 and the Y-axis pressure sensor 34 are arranged on the other side of the test site 1.

[0052] The Y-axis pressure sensor 34 is in transmission connection with the output end of the Y-axis driving part 32, and the second Y-axis pressing plate 33 is arranged on the side of the Y-axis pressure sensor 34 away from the Y-axis driving part 32.

[0053] When the battery 7 is tested along the Y-axis, the Y-axis driving part 32 drives the second Y-axis pressing plate 33 to extend, so that one side of the battery 7 along the Y-axis abuts against the Y-axis reference positioning part 31 and the other side abuts against the second Y-axis pressing plate 33. The Y-axis driving part 32 increases the output power to press the battery 7, and the Y-axis pressure sensor 34 is used to sense the pressure of the battery 7 along the Y-axis direction to perform the pressure test. It can be seen that the structure of the Y-axis test group 3 is simple and the manufacturing cost is low.

[0054] Further, the Y-axis test group 3 further comprises a second follower 35, and the Y-axis reference positioning part 31 further comprises a positioning driving part 311, a first Y-axis pressing plate 312 and a first follower 313.

[0055] The output end of the positioning driving member 311 is in transmission connection with the first follower 313, and the first Y-axis pressing plate 312 is arranged on the side of the first follower 313 away from the positioning driving member 311;

[0056] The second follower 35 is arranged between the second Y-axis pressing plate 33 and the Y-axis driving member 32;

[0057] When the battery in the test position 1 moves along the X-axis direction, the second follower 35 drives the second Y-axis pressing plate 33 to move synchronously with the battery, and the first follower 313 drives the first Y-axis pressing plate 312 to move synchronously.

[0058] During the operation of the mechanism, the battery 7 is pushed by the X-axis test group 2 to move along the X-axis direction. In order to avoid the friction between the battery 7 and the first Y-axis pressing plate 312 and the second Y-axis pressing plate 33 and damage the surface of the battery 7, the second follower 35 and the first follower 313 are arranged to drive the first Y-axis pressing plate 312 and the second Y-axis pressing plate 33 to move synchronously with the battery 7. Therefore, while the Y-axis test group 3 performs the pressure test, the surface of the battery 7 is not damaged due to the pushing of the X-axis test group 2, and the structure of the battery 7 is not damaged by the mechanism, so as to affect the performance and appearance of the battery.

[0059] Specifically, the first follower 313 and the second follower 35 can be any one of the mechanical follower structures in the prior art, such as a gear transmission structure or a roller structure.

[0060] Specifically, the X-axis test group 2 comprises an X-axis pressing plate 21, an X-axis driving member 22, an X-axis pressure sensor 23 and an X-axis reference positioning member 24.

[0061] The output end of the X-axis driving member 22 is in transmission connection with the X-axis pressure sensor 23, and the X-axis pressing plate 21 is arranged at the end of the X-axis pressure sensor 23 away from the X-axis driving member 22.

[0062] When the battery 7 is subjected to the pressure test along the X-axis, the X-axis driving member 22 drives the X-axis pressing plate 21 to extend until the side of the battery 7 along the X-axis abuts against the X-axis pressing plate 21 and the other side abuts against the X-axis reference positioning member 24. The X-axis driving member 22 increases the output power to press the battery 7. At this time, the X-axis pressure sensor 23 is used to sense the pressure on the battery 7 along the X-axis direction, so as to perform the pressure test. It can be seen that the structure of the X-axis test group 2 is simple and the manufacturing cost is low.

[0063] Specifically, the Z-axis test group further comprises a Z-axis test group rack 5, a transplanting platform 61 and a sliding rail 62.

[0064] The Z-axis test group 4 is installed on the Z-axis test group rack 5.

[0065] The X-axis test group 2, the Y-axis test group 3 and the test site 1 are arranged on the transplanting platform 61 which slides on the slide rail 62; therefore, the positions of the X-axis test group 2, the Y-axis test group 3 and the test site 1 are movable, when the transplanting platform 61 moves to the position below the Z-axis test group 4, the X-axis test group 2, the Y-axis test group 3 and the Z-axis test group 4 can simultaneously perform the pressure test on the battery 7, thereby further reducing the working time required for the pressure test; and after or before the pressure test, the test site 1 is on the transplanting platform 61 and slides along the slide rail 62 out of the range of the Z-axis test group rack 5, so that more space is provided for the worker to place the battery 7 on the test site 1 or take the battery 7 out of the test site 1, thereby facilitating the operation and improving the detection efficiency.

[0066] Specifically, the Z-axis test group rack 5 is a gantry frame.

[0067] Specifically, the slide rail 62 is a plurality of slide rails which are arranged in parallel with each other, so as to provide more support points for the transplanting platform 61 and ensure that the transplanting platform 61 can stably slide on the slide rail 62.

[0068] More specifically, the mobile driving member 63 is further included, an output end of the mobile driving member 63 is in transmission connection with the transplanting platform 61, and the mobile driving member 63 is used to drive the transplanting platform 61 to slide on the slide rail 62 in the X-axis direction or the Y-axis direction. The mobile driving member 63 can accurately control the movement amount of the transplanting platform 61, thereby reducing the error caused by manual operation.

[0069] As an example, the mobile driving member 63 is a linear motor.

[0070] More specifically, the Z-axis test group 4 includes a Z-axis driving member 41, a Z-axis pressure sensor 42 and a Z-axis pressing plate 43.

[0072] When the pressure test on the battery 7 along the Z-axis is performed, the Z-axis driving member 41 drives the Z-axis pressing plate 43 to extend until the Z-axis pressing plate 43 abuts against the battery 7, the Z-axis driving member 41 increases the output power to pressurize the battery 7, and at this time, the Z-axis pressure sensor 42 is used to sense the pressure on the battery 7 along the Z-axis direction, thereby performing the pressure test; it can be seen that the structure of the Z-axis test group 4 is simple and the manufacturing cost is low.

[0073] More specifically, the first Y-axis pressing plate 312, the second Y-axis pressing plate 33, the X-axis reference positioning member 24, the part adjacent to the test site 1 of the transplanting platform 61 and the surface of the Z-axis pressing plate 43 are provided with flexible conductive layers, and each flexible conductive layer is electrically connected and arranged in series, and the conductive part 211 is arranged on the X-axis pressing plate 21. The flexible conductive layer can avoid rigid contact with the battery 7, reduce damage to the battery 7, and also wrap the R angle between each face of the battery 7, so as to detect whether the battery R angle has insufficient pressure strength or electrolyte leakage.

[0074] Specifically, the flexible conductive layer comprises a conductive cloth layer and a conductive sponge layer.

[0075] More specifically, the first Y-axis pressing plate 312, the second Y-axis pressing plate 33, the X-axis reference positioning member 24, the part adjacent to the test site 1 of the transplanting platform 61 and the Z-axis pressing plate 43 are all made of insulating materials.

[0076] The arrangement of the insulating material can ensure that the first Y-axis pressing plate 312, the second Y-axis pressing plate 33, the X-axis reference positioning member 24, the part adjacent to the test site 1 of the transplanting platform 61 and the test site 1 are in an insulating state, so as to avoid the performance of the mechanism being damaged due to the leakage of the battery 7, and affect the service life of the mechanism.

The mechanism has the advantages of the battery test group, and the mechanism can detect two batteries at a time, so that the detection efficiency is higher.

[0079] More specifically, the X-axis test groups 2 of the two test groups are arranged in opposite directions, so that when the X-axis test groups 2 are working, the force directions of the X-axis test groups 2 are opposite, and the two X-axis reference positioning members 24 can keep a stable positional relationship under the action of the opposite pressure, so that the stability of the single-station two-battery six-surface insulation voltage resistance detection mechanism is stronger.
