[0054] The automatic plug-in test device described in this embodiment is used in battery manufacturing, especially in the automatic plug-in test mechanism of battery packs, which has the advantages of convenience, high efficiency, and strong practicality. Figures 1-9 As shown, the automatic plug-in test device includes a linear drive mechanism 100, a rotary drive mechanism 200, a micro-floating mechanism 300, a high-voltage connection terminal 400, and a low-voltage connection terminal 500. The automatic plug-in test device has a first direction, a second direction, and a third direction that intersect each other. Optionally, the first direction, the second direction, and the third direction are mutually perpendicular.

[0056] The driving end of the linear drive mechanism 100 is directly or indirectly connected to the rotary drive mechanism 200, enabling the rotary drive mechanism 200 to reciprocate in a first direction. The micro-floating mechanism 300 moves synchronously with the rotary drive mechanism 200 in the first direction. When the micro-floating mechanism 300 reciprocates in the first direction with the rotary drive mechanism 200, the high-voltage connection terminal 400 and the low-voltage connection terminal 500 connected to the micro-floating mechanism 300 can also reciprocate in the first direction.

[0058] The automatic plug-in test device described in this embodiment drives the rotary drive mechanism 200 to move back and forth in the first direction through the linear drive mechanism 100, thereby driving the micro-floating mechanism 300 to move back and forth in the first direction, and then causing the high-voltage connection terminal 400 and the low-voltage connection terminal 500 to move back and forth in the first direction; drives the micro-floating mechanism 300 to rotate around the first direction through the rotary drive mechanism 200, thereby causing the high-voltage connection terminal 400 and the low-voltage connection terminal 500 to rotate around the first direction; the micro-floating mechanism 300 can adjust the positions of the high-voltage connection terminal 400 and the low-voltage connection terminal 500 to fine-tune the positions of the high-voltage connection terminal 400 and the low-voltage connection terminal 500, so as to facilitate the high-voltage connection terminal 400 and the low-voltage connection terminal 500 to be respectively plugged into the battery pack high-voltage terminal 600 and the battery pack low-voltage terminal 700. The automatic plug-in test device can realize automatic plug-in of the plug-in test device. It has a relatively simple structure, relatively low manufacturing cost, and relatively high safety. It does not require manual plug-in, which can effectively liberate labor and improve test efficiency. Its operation is relatively convenient.

[0073] See also Figure 1-Figure 4 As shown, in an optional solution of this embodiment, a connector 110 for connecting to a robotic arm is fixedly connected to the fixed end of the linear drive mechanism 100. The connector 110 facilitates the connection of the linear drive mechanism 100 to the robotic arm, thereby facilitating the robotic arm to drive the automatic plug-in test device to a preset position via the linear drive mechanism 100. The robotic arm may be, for example, a three-axis motion mechanism, a robot, or another motion mechanism.

[0074] In the prior art, during the production process of batteries, electronic devices such as relays, fuses, shunts, and BMS (battery management system) need to be installed inside. The connection integrity of the battery pack is guaranteed by the connection of copper busbars and wiring harnesses. In order to check the connection integrity and reliability, EOL testing (End of Line Testing, automobile production line off-line detector testing) needs to be performed when the battery is offline. Existing testing equipment requires manual insertion of the test plug from a specific test cabinet to the battery pack. Whether the manual insertion test is in place varies from person to person, and it is impossible to know whether the connector contact is good. In the case of poor contact, starting the test equipment will cause the battery pack to short-circuit and burn. The test equipment operates at high voltage and high current, and there are great safety hazards when operated by personnel. Personnel are prone to make mistakes in plugging and testing, resulting in low production efficiency and high labor intensity for employees.

[0075] The automatic plug-in test device provided by the present invention can effectively solve the above-mentioned problems of manual plug-in testing to determine whether the connection is in place and whether the connector contact is good. First, the battery pack flows to the EOL test station along with the tooling plate. The lifting cylinder on the assembly line lifts the tooling plate and the battery pack to complete the positioning of the battery pack. The barcode scanner scans the tooling plate code and simultaneously triggers the three-axis movement mechanism to move to the preset test point. The linear drive mechanism 100 drives the micro-floating mechanism 300 to move along the first direction with the rotary drive mechanism 200 to begin automatically docking the battery pack high-voltage terminal 600 and the battery pack low-voltage terminal 700. The rotary drive mechanism 200 drives the micro-floating mechanism 300 to rotate the micro-floating mechanism 300 slightly around the first direction to adjust the automatic docking angle. The micro-floating mechanism 300 fine-tunes the position of the high-voltage connection terminal 400 and the low-voltage connection terminal 500 so that the high-voltage connection terminal 400 and the low-voltage connection terminal 500 are respectively plugged into the battery pack high-voltage terminal 600 and the battery pack low-voltage terminal 700. After the battery pack is automatically connected, the EOL equipment is triggered to start the test. If the test result is OK (qualified), the battery pack will be processed in the subsequent process; if the test result is NG (failed), the product will be marked and returned for repair after the product is offline.

[0076] The specific plugging process of the automatic plug-in test device provided by the utility model is as follows:

[0077] The battery pack moves to the battery pack testing station;

[0078] The automatic plug-in test device moves to the battery pack interface;

[0079] The linear drive mechanism 100 drives the micro-floating mechanism 300 to move along the first direction with the rotary drive mechanism 200, so that the guide member 330 on the micro-floating mechanism 300 automatically mechanically positions the battery pack guide structure 800;

[0080] The linear drive mechanism 100 continues to drive the micro-floating mechanism 300 to move along the first direction with the rotary drive mechanism 200 . The high-voltage connection terminal 400 and the low-voltage connection terminal 500 on the micro-floating mechanism 300 are respectively plugged into the battery pack high-voltage terminal 600 and the battery pack low-voltage terminal 700 .

[0081] If there is a deviation between the insertion position of the automatic plug-in test device and the battery pack interface, adjustments can be made to ensure accurate insertion: 1) The rotary drive mechanism 200 can rotate at a certain angle; 2) The micro-floating mechanism 300 adaptively fine-tunes the position of the high-voltage connection terminal 400 and the low-voltage connection terminal 500; The above floating can ensure that the automatic plug-in test device can be smoothly inserted into the battery pack interface.

[0082] After the test is completed, the test device is automatically plugged out of the battery pack interface.

[0083] The above operations are cyclically performed to realize automatic plug-in test of the battery pack.

[0084] The above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention. Those skilled in the art will readily appreciate that the present invention is susceptible to various modifications and variations. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of the present invention shall be included within the scope of protection of the present invention.
