Description

Technical Field

[0001] This utility model relates to the field of battery testing technology, and in particular to an automatic testing bench for lithium battery packs. Background Technology

[0002] Lithium batteries are key energy components in modern electronic devices and new energy vehicles, and their performance and quality directly affect the operational stability, safety, and lifespan of these devices. Comprehensive and accurate performance testing of lithium battery packs is crucial during the production and research and development of lithium batteries. However, traditional lithium battery pack testing methods have several problems:

[0003] On the one hand, traditional test benches often use simple clamps or manual fixing methods to secure lithium battery packs. This method makes it difficult to accurately position battery packs of different specifications, leading to displacement or shaking during testing. On the other hand, dust and debris on the surface of lithium battery packs can significantly affect test results. Dust may cause poor electrode contact, interfering with electrical performance testing; some corrosive debris may also damage the battery pack's outer shell or internal structure. However, traditional test benches often lack effective cleaning methods, relying heavily on manual wiping, which is not only inefficient but also makes it difficult to ensure thorough cleaning, thus affecting the reliability of test results. Furthermore, the operation of traditional test benches is largely manual, from loading and securing the battery packs to parameter adjustments, data recording, and unloading during testing, all requiring extensive manual operation. This not only increases labor costs and intensity but also makes it difficult to guarantee consistency and accuracy for each test due to the variability in manual operation. Simultaneously, manual operation is slow, failing to meet the demands of rapid testing of lithium battery packs in large-scale production, thus hindering the improvement of production efficiency. Utility Model Content

[0004] To overcome the above shortcomings, this utility model provides an automatic test bench for lithium battery packs, which aims to improve the problem of the lack of effective cleaning in traditional test benches in the prior art.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: an automatic testing bench for lithium battery packs, comprising a workbench, a rotating assembly fixedly installed on the upper part of the workbench, a plurality of clamping assemblies arranged on the upper part of the rotating assembly, each clamping assembly including two fixing blocks, each fixing block having a plurality of springs arranged on its inner side, each spring having a clamping plate fixedly installed at one end, and each clamping plate having an anti-slip pad fixedly installed on its inner side; a plurality of fixing assemblies arranged on the upper part of the rotating assembly; fixed air blowing assemblies fixedly installed on both sides of the upper part of the workbench, each fixed air blowing assembly including L-shaped blocks fixedly installed on both sides of the upper part of the workbench, each L-shaped block having an arc groove at one end; a cleaning assembly also arranged on the upper part of the fixed air blowing assembly; a detection device fixedly installed at the rear end of the workbench, with lighting lamps arranged at both ends of the upper part of the detection device; and a controller fixedly installed at the front end of the workbench.

[0006] As a further description of the above technical solution:

[0007] The rotating assembly includes a shock-absorbing pad fixedly installed on the upper part of the workbench. A fixing groove is fixedly installed on the upper part of the shock-absorbing pad. A motor is fixedly installed inside the fixing groove. The output end of the motor is fixedly connected to the rotating platform. A partition plate is provided on the upper part of the rotating platform.

[0008] As a further description of the above technical solution:

[0009] The fixing component includes multiple positioning holes formed on the upper part of the rotating platform, and the fixing component also includes a battery pack, the bottom of which is provided with multiple positioning pins.

[0010] As a further description of the above technical solution:

[0011] The fixed air blowing assembly also includes an L-shaped block with a fixed plate fixedly installed on its upper part. An electric fan is installed inside the fixed plate, and an air outlet is provided at one end of the electric fan.

[0012] As a further description of the above technical solution:

[0013] The cleaning assembly includes an electric slide rail fixedly mounted on the upper part of another L-shaped block, and a cleaning brush on the upper part of the electric slide rail moving seat.

[0014] As a further description of the above technical solution:

[0015] Each of the plurality of positioning holes corresponds one-to-one with a plurality of positioning pins.

[0016] As a further description of the above technical solution:

[0017] The rotating platform is rotatably connected to the arc-shaped groove.

[0018] As a further description of the above technical solution:

[0019] The cleaning brush always remains in contact with the battery pack.

[0020] This utility model has the following beneficial effects:

[0021] In this invention, the bottom positioning pin of the battery pack is inserted into the positioning hole of the rotating platform. The spring in the clamping assembly pushes the clamping plate, and the anti-slip pad increases the friction, ensuring that the battery pack will not shift or shake during testing. This not only ensures the accuracy of the test data and avoids test errors caused by changes in the position of the battery pack, but also makes the testing process more stable and reliable, reduces test interruptions caused by battery pack instability, improves testing efficiency, and provides a strong guarantee for the accurate evaluation of battery pack performance.

[0022] In this invention, during the rotation of the battery pack, the electric fan of the fixed air-blowing component blows out airflow, which can initially remove loose dust and debris from the surface of the battery pack. The electric slide rail of the cleaning component drives the cleaning brush to move along the surface of the battery pack, and the cleaning brush always remains in contact with the battery pack for further cleaning, preventing dust and debris from affecting the testing. Dust and other impurities may affect the contact of the battery pack electrodes and interfere with electrical performance testing. The cleaning function eliminates these interfering factors, enabling the testing device to obtain more accurate battery pack performance data and ensuring that the test results truly reflect the actual condition of the battery pack.

Detailed Implementation

[0030] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0031] Reference Figure 1-5 An embodiment of this utility model provides an automatic testing bench for lithium battery packs, including a workbench 1. A rotating assembly 2 is fixedly installed on the upper part of the workbench 1. Multiple clamping assemblies 3 are provided on the upper part of the rotating assembly 2. Each clamping assembly 3 includes two fixing blocks 301. Multiple springs 302 are provided on the inner side of each of the two fixing blocks 301. A clamping plate 303 is fixedly installed on one end of each of the multiple springs 302. An anti-slip pad 304 is fixedly installed on the inner side of each of the two clamping plates 303. Multiple fixing assemblies 4 are provided on the upper part of the rotating assembly 2. Fixed air blowing assemblies 5 are fixedly installed on both sides of the upper part of the workbench 1. Each fixed air blowing assembly 5 includes L-shaped blocks 501 fixedly installed on both sides of the upper part of the workbench 1. An arc groove 502 is opened on one end of each of the two L-shaped blocks 501. A cleaning assembly 6 is also provided on the upper part of the fixed air blowing assembly 5. A detection device 7 is fixedly installed at the rear end of the workbench 1. Lighting lamps 8 are provided at both ends of the upper part of the detection device 7. A controller 9 is fixedly installed at the front end of the workbench 1.

[0032] The rotating assembly 2 includes a shock-absorbing pad 200 fixedly installed on the upper part of the workbench 1. A fixing groove 201 is fixedly installed on the upper part of the shock-absorbing pad 200. A motor 202 is fixedly installed inside the fixing groove 201. A rotating platform 203 is fixedly connected to the output end of the motor 202. A dividing plate 204 is provided on the upper part of the rotating platform 203.

[0033] The rotating platform 203 is rotatably connected to the arc-shaped groove 502;

[0034] Specifically, the shock-absorbing pad 200 is installed on the upper part of the workbench 1. Its main function is to reduce the vibration generated by the motor 202 during operation and transmit it to the workbench 1 and other components, preventing vibration from interfering with the test results of the battery pack 402 and ensuring the accuracy of the test data. The fixing slot 201 is fixed on the upper part of the shock-absorbing pad 200, providing a stable installation space for the motor 202, which can drive the rotating platform 203 to rotate smoothly. The rotating platform 203 is the carrier for placing the battery pack 402. The dividing plate 204 set on its upper part divides the rotating platform 203 into multiple areas, each of which can hold one battery pack 402, facilitating the simultaneous testing of multiple battery packs 402, improving testing efficiency, and the dividing plate 204 can also prevent the battery packs 402 from colliding with each other to a certain extent.

[0035] The fixing component 4 includes multiple positioning holes 401 opened on the upper part of the rotating platform 203. The fixing component 4 also includes a battery pack 402, and multiple positioning pins 403 are provided at the bottom of the battery pack 402.

[0036] Each of the multiple positioning holes 401 corresponds to a single positioning pin 403;

[0037] Specifically, the multiple positioning holes 401 on the upper part of the rotating platform 203 precisely match the positioning pins 403 on the bottom of the battery pack 402. The battery pack 402 is the object being tested. When the battery pack 402 is placed, the multiple positioning pins 403 on its bottom can accurately insert into the corresponding positioning holes 401 on the rotating platform 203, achieving preliminary and accurate positioning of the battery pack 402 on the rotating platform 203. This lays the foundation for subsequent clamping and testing, ensuring the positional accuracy of the battery pack 402 during testing and avoiding errors in the test results due to positional deviations.

[0038] The fixed air blowing assembly 5 also includes an L-shaped block 501 on which a fixing plate 503 is fixedly installed. An electric fan 504 is provided inside the fixing plate 503, and an air outlet 505 is provided at one end of the electric fan 504.

[0039] Specifically, in the fixed air blowing assembly 5, the fixing plate 503 on the upper part of the L-shaped block 501 provides a mounting platform for the electric fan 504. The electric fan 504 is installed inside the fixing plate 503 and can generate airflow. The air outlet 505 at one end is specially designed to guide the airflow accurately towards the surface of the battery pack 402. During the rotation of the battery pack 402, the electric fan 504 starts, and the airflow blows away some loose dust and debris on the surface of the battery pack 402, performing preliminary cleaning work. This creates better conditions for the subsequent fine cleaning by the cleaning assembly 6, ensuring the cleanliness of the surface of the battery pack 402 and reducing the impact of dust and debris on the inspection of the battery pack 402.

[0040] Cleaning component 6 includes an electric slide rail 601 fixedly mounted on the upper part of another L-shaped block 501, and a cleaning brush 602 on the upper part of the moving seat of the electric slide rail 601;

[0041] The cleaning brush 602 must always remain in contact with the battery pack 402;

[0042] Specifically, the electric slide rail 601 of the cleaning component 6 is fixedly mounted on the upper part of another L-shaped block 501. Under the control of the controller 9, the electric slide rail 601 can drive the cleaning brush 602 to move along a specific trajectory. The cleaning brush 602 is mounted on the upper part of the moving seat of the electric slide rail 601. During the rotation of the battery pack 402, the cleaning brush 602, driven by the electric slide rail 601, always keeps in contact with the battery pack 402, performing a comprehensive and meticulous cleaning of the surface of the battery pack 402. This thoroughly removes the dust and debris that the fixed air blowing component 5 failed to clean, further ensuring the cleanliness of the surface of the battery pack 402 and ensuring that the detection device 7 can obtain accurate detection data.

[0043] Working principle: First, place the battery pack 402 in the test position. Align the positioning pin 403 at the bottom of the battery pack 402 with the positioning hole 401 on the upper part of the rotating platform 203 and insert it to achieve initial positioning of the battery pack 402. The positioning hole 401 and the positioning pin 403 correspond one-to-one to ensure the accurate positioning of the battery pack 402. Subsequently, multiple springs 302 on the inner side of the two fixing blocks 301 in the clamping assembly 3 push the clamping plate 303. The anti-slip pad 304 on the inner side of the clamping plate 303 tightly adheres to the battery pack 402. Utilizing the elasticity of the springs 302 and the friction of the anti-slip pad 304, the battery pack 402 is firmly fixed on the rotating platform 203, preventing displacement or shaking of the battery pack 402 during the test.

[0044] The output of the motor 202 in the rotating assembly 2 drives the rotating platform 203 to rotate. The rotating platform 203 is connected to the workbench 1 through a shock-absorbing pad 200, which reduces the impact of vibration generated by the motor 202 on the test. When the rotating platform 203 rotates, it drives the battery pack 402 placed on it to rotate as well. Because the rotating platform 203 is rotatably connected to the arc groove 502 on the L-shaped block 501 of the fixed air blowing assembly 5, the rotation of the rotating platform 203 is more stable.

[0045] During the rotation of the battery pack 402, the electric fan 504 in the fixed air blowing assembly 5 is activated, and the generated airflow is blown out through the air outlet 505 to initially blow away some loose dust and debris from the surface of the battery pack 402. At the same time, the electric slide rail 601 of the cleaning assembly 6 drives the cleaning brush 602 to move along the surface of the battery pack 402. The cleaning brush 602 always keeps in contact with the battery pack 402 to further clean the surface of the battery pack 402, ensuring that the surface of the battery pack 402 is clean and preventing dust and debris from affecting the test results.

[0046] When the battery pack 402 rotates with the rotating platform 203 to the position of the testing device 7, the testing device 7, under the control of the controller 9, tests various performance parameters of the battery pack 402, such as voltage, current, capacity, and internal resistance. The lights 8 at both ends of the upper part of the testing device 7 illuminate to provide sufficient light for the testing, making the testing more accurate. The controller 9 receives the data from the testing device 7, analyzes and processes it, and determines whether the battery pack 402 is qualified according to preset standards.

[0047] Throughout the testing process, operators can control and monitor the test bench via controller 9. Controller 9 can control the start / stop and speed of motor 202, adjust the wind speed of electric fan 504 in fixed air blowing assembly 5, and control the moving speed and stroke of electric slide rail 601 in cleaning assembly 6. Operators can also view test data and results on controller 9, and make timely adjustments or handle any abnormalities.

[0048] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
