[0066] In addition, the technical features involved in the different embodiments of the application described below can be combined with each other as long as they do not conflict with each other.

[0067] As described in the background, in the related art battery testing device, sometimes the plug of the battery testing device needs to be plugged into the socket of the battery device. The existing battery testing device uses a flow type plugging device to operate the plug. Due to positioning deviation, the success rate of automatic plugging is low, and frequent faults such as jamming and misalignment occur, affecting the continuity of system operation, or manual intervention is required to complete the plugging operation, resulting in long test cycle, low utilization rate of battery testing device, and difficulty in meeting the needs of large-scale production scenarios. Therefore, the plugging success rate has a great influence on the efficiency of battery testing.

[0068] Based on this, the battery testing device is provided, the connecting end of the mechanical arm is connected to the device total frame, the plug driving device for driving the plug to move relative to the testing frame is further included in the plug connecting device, and / or the testing frame driving device for driving the testing frame to move relative to the device total frame is included in the battery testing device, and the operation mechanism is arranged at the free end of the mechanical arm, so that the plug can be accurately inserted into the socket of the battery pack to be tested along the plug-in direction, the accuracy and success rate of plug connection are improved, and the testing efficiency of the battery testing device is improved.

[0069] As shown in Figures 1 to 10 , the battery testing device includes: a device total frame 1; a mechanical arm 2 including a connecting end 22 and a free end 21 arranged oppositely, the connecting end 22 being connected to the device total frame 1; a testing frame 3 connected to the device total frame 1; a plug connecting device 4 arranged on the testing frame 3 and including a plug 41, the plug connecting device 4 further including a plug driving device 42 for driving the plug 41 to move relative to the testing frame 3, and / or the battery testing device including a testing frame driving device 9 for driving the testing frame 3 to move relative to the device total frame 1, and the plug 41 can be positioned at a counter-plug position opposite to the socket B1 of the battery pack B to be tested, so that the plug 41 can only move along the plug-in direction close to and away from the socket B1; and an operation mechanism 5 arranged at the free end 21 of the mechanical arm 2 and configured to hold the plug 41 at the counter-plug position and insert the plug 41 into the socket B1 along the plug-in direction under the driving of the mechanical arm 2.

[0070] By connecting the connecting end 22 of the mechanical arm 2 to the device total frame 1, the plug driving device 42 for driving the plug 41 to move relative to the testing frame 3 is further included in the plug connecting device 4, and / or the testing frame driving device 9 for driving the testing frame 3 to move relative to the device total frame 1 is included in the battery testing device, the operation mechanism 5 holds the plug 41 at the counter-plug position and inserts the plug 41 into the socket B1 along the plug-in direction, the mechanical arm 2 can be stably arranged on the device total frame 1 during the insertion of the plug 41 into the socket B1, and basically only force needs to be applied to the plug 41 along the plug-in direction, so that the plug 41 can be accurately inserted into the socket B1 of the battery pack B to be tested, the accuracy and success rate of plug connection are improved, and the testing efficiency of the battery testing device is improved. In addition, the plug 41 is inserted into the socket B1 by the operation mechanism 5, which is more consistent and reliable than manual plug connection, so as to improve the automation level of the battery testing device.

[0071] As shown in Figures 2 to 4 , in some embodiments of the battery testing device, the connecting end 22 of the mechanical arm 2 is movably connected to the device total frame 1.

[0072] By movably connecting the connecting end 22 of the mechanical arm 2 with the device general frame 1, the activity range of the mechanical arm 2 is increased, so that the battery testing device can be adapted to different models of battery packs B and different testing scenarios, thereby improving the application range of the battery testing device.

[0073] As shown in the battery testing device in some embodiments, Figures 2 to 4 the battery testing device further comprises a mechanical arm track assembly 8, and the connecting end 22 of the mechanical arm 2 is movably connected with the device general frame 1 through the mechanical arm track assembly 8.

[0074] By movably connecting the connecting end 22 of the mechanical arm 2 with the device general frame 1 through the mechanical arm track assembly 8, not only the activity range of the mechanical arm 2 is increased, but also the stability and movement accuracy of the mechanical arm 2 during movement are improved, thereby improving the accuracy and success rate of the plug 41 and the socket B1.

[0075] As shown in the battery testing device in some embodiments, Figures 2 to 4 the mechanical arm track assembly 8 comprises a first mechanical arm track 81 extending along a horizontal first direction X, and the connecting end 22 of the mechanical arm 2 is movably arranged on the first mechanical arm track 81 along the first mechanical arm track 81; and a second mechanical arm track 82 connected with the device general frame 1 and extending along a horizontal second direction Y perpendicular to the first direction X, and the first mechanical arm track 81 is movably arranged on the second mechanical arm track 82 along the second mechanical arm track 82.

[0076] By setting the first mechanical arm track 81 extending along the horizontal first direction X and the second mechanical arm track 82 extending along the horizontal second direction Y perpendicular to the first direction X, the mechanical arm 2 can realize accurate movement in the horizontal range, so that the plug 41 and the socket B1 can be connected at any position in the testing area by the operating mechanism 5. In addition, the track structure of the first mechanical arm track 81 and the second mechanical arm track 82 is conducive to ensuring the stability and movement accuracy of the mechanical arm 2 during movement, thereby improving the accuracy and success rate of the plug 41 and the socket B1.

[0077] As shown in the battery testing device in some embodiments, Figure 3 the mechanical arm 2 is a six-axis mechanical arm.

[0078] The mechanical arm 2 adopts the form of a six-axis mechanical arm, which has higher degrees of freedom, is conducive to adjusting the angle and position of the operating mechanism 5, is conducive to adapting to more complex use scenarios, and thereby improves the adaptability and reliability of the battery testing device.

[0079] As shown in the battery testing device in some embodiments, Figures 5 to 6As shown, in some embodiments of the battery testing apparatus, the plug driving device 42 further includes a plug mounting base 421, which is mounted on the test frame 3. The plug 41 is mounted on the plug mounting base 421 and is reciprocally movable relative to the plug mounting base 421 along the insertion / removal direction.

[0080] By setting the plug mounting base 421, and setting the plug 41 to be reciprocally movable relative to the plug mounting base 421 along the insertion and removal direction, the degree of freedom of movement of the plug 41 relative to the plug mounting base 421 in other unnecessary directions is effectively restricted. This helps to reduce insertion failure due to angular deviation and to reduce damage to the plug 41 and the socket B1. As a result, it helps to improve the accuracy and success rate of plug 41 and socket B1 insertion, improve the testing efficiency of the battery testing device, and enhance the service life of the battery testing device.

[0081] like Figures 5 to 6 As shown, in some embodiments of the battery testing apparatus, the plug mounting base 421 is movably mounted on the test frame 3.

[0082] By setting the plug mounting base 421 to be movably mounted on the test frame 3, it is convenient to adjust the position of the plug 41 and ensure that the plug 41 and the socket B1 are aligned in the insertion direction, thereby improving the accuracy and success rate of plug 41 and socket B1 insertion.

[0083] like Figures 5 to 6 As shown, in some embodiments of the battery testing apparatus, the plug drive device 42 further includes a base track assembly 422, and the plug mounting base 421 is movably connected to the test frame 3 via the base track assembly 422.

[0084] By setting the base track assembly 422, the plug mounting base 421 can move stably through the base track assembly 422, which helps to improve the stability and movement accuracy of the plug mounting base 421 during the movement process, thereby improving the accuracy and success rate of plug 41 and socket B1 insertion.

[0129] A battery test method of the battery test device of an embodiment of the application is described below.

[0130] The transport vehicle 6 first transports the battery pack B to be tested to a test position of the battery test device.

The fingers 521 of the clamping part 52 clamp the plug 41, and the six-axis mechanical arm applies force to insert the plug 41 into the socket B1. During this process, the corresponding auxiliary plug-in device 44 of the plug 41 cooperates with the movement of the plug 41. If there are multiple plugs 41 that need to be mated with multiple sockets B1 respectively, the six-axis mechanical arm completes the mating operation with each plug 41 one by one.

[0135] The test is performed. The test is, for example, a gas tightness test such as a helium leak test on the battery pack B.

[0136] After the test is completed, the plug 41 is pulled out of the socket B1 by the auxiliary plug-in device 44 of the plug-in device 4.
