Description

Technical Field

[0002] In the field of lithium battery pack failure analysis, comprehensive and detailed testing of the entire lithium battery pack is required. Traditional testing methods can perform partial testing of lithium batteries to a certain extent, providing some basic information for analyzing the causes of lithium battery failures and playing a role in the development of this field.

[0003] Traditional lithium battery pack testing methods typically use fixed fixtures to position the battery pack, making it difficult to perform multi-angle and all-round testing, resulting in insufficient comprehensiveness. Regarding surface cleaning, traditional equipment relies heavily on manual wiping or simple brush cleaning, lacking automated cleaning and dust removal systems. This makes it difficult to effectively remove dust and impurities from the battery pack surface, and the lack of dust collection and treatment during cleaning easily leads to environmental pollution. Furthermore, traditional fixing methods mostly use rigid mechanical clamps, which cannot flexibly adjust the clamping force according to the size of the battery pack, posing a risk of unstable fixing or excessive compression, potentially leading to testing errors or safety hazards. Overall, the testing efficiency, accuracy, and safety all need improvement.

[0004] Existing testing equipment and methods have many shortcomings. On the one hand, most equipment is difficult to flexibly flip the entire lithium battery pack, which makes it impossible to fully test the condition of all sides of the lithium battery and easily miss key failure information. On the other hand, dust or impurities may be present on the surface of the lithium battery pack, affecting the accuracy of the test results. However, existing equipment often lacks an effective cleaning mechanism. In addition, some equipment is not flexible enough in terms of space adjustment and cannot provide sufficient space for flipping the lithium battery pack, which limits the comprehensiveness and convenience of the test.

[0021] Reference Figure 1 The detection platform 1 is a horizontal plate structure with a slot in the middle for connecting the air intake grille 72 inside the dust removal mechanism 7.

[0022] Reference Figure 2 The lifting mechanism 2 includes a support plate 21. Hydraulic cylinders 22 are provided on both sides of the bottom of the support plate 21. The output end of the hydraulic cylinder 22 passes through the support plate 21 and is fixedly connected to a U-shaped plate 23. The top two sides of the U-shaped plate 23 are fixedly connected to the bottom of the first vertical plate 31 and the second vertical plate 32, respectively. Hydraulic cylinders 22 are also installed below the two open ends of the U-shaped plate 23. The two hydraulic cylinders 22 here are fixed to the bottom plate 6, and the output end of the hydraulic cylinder 22 passes through the detection platform 1 and is connected to the two open ends of the U-shaped plate 23. The simultaneous operation of the four hydraulic cylinders 22 can drive the U-shaped plate 23 and the flipping and fixing mechanism 3 on it to move vertically. It should be noted that the hydraulic cylinder 22 is a conventional device in the field. This application only uses it and does not make any improvements. Therefore, its principle and structure will not be described in detail.

[0023] The lifting mechanism 2 of this application uses the extension and retraction of the hydraulic cylinder 22 to drive the tilting and fixing mechanism 3 to lift and lower. It can flexibly adjust the height, providing sufficient space for the tilting and fixing mechanism 3 to tilt the entire lithium battery pack, enhancing the spatial adaptability of the equipment, making the testing operation more convenient, and further improving the comprehensiveness of the testing.

[0024] Reference Figure 3The flipping and fixing mechanism 3 includes a first vertical plate 31, a second vertical plate 32, a first motor 33, a first hydraulic cylinder 34, a connecting plate 35, and a fixing member 36. The first vertical plate 31 and the second vertical plate 32 are respectively installed on the top two sides of the U-shaped plate 23 and above the detection platform 1. The fixing member 36 is movably connected to the opposite side of the first vertical plate 31 and the second vertical plate 32.

[0025] A first motor 33 is installed on the outside of the first vertical plate 31. The first motor 33 passes through the first vertical plate 31 and is connected to the corresponding fixing member 36. Therefore, the first motor 33 can drive the fixing member 36 at that location to rotate 360°.

[0026] A connecting plate 35 is provided between the second vertical plate 32 and the fixing member 36, wherein the connecting plate 35 is rotatably connected to the fixing member 36, and the connecting plate 35 is detachably connected to the first hydraulic cylinder 34 provided on the rear side of the second vertical plate 32.

[0028] This application, through the design of the fixing frame 361, the second electric telescopic rod 362, and the clamping plate 363, can flexibly adjust the clamping force according to the size of the lithium battery pack, ensuring that the lithium battery pack is firmly fixed during the flipping process, avoiding detection errors or safety issues caused by unstable fixing, and improving the stability and safety of detection.

The bottom of the housing 41 is connected to the top of the detection platform 1. The second motor 42 is installed at one end of the housing 41. The lead screw 43 is movably connected to the inner wall of the housing 41 through a bearing. One end of the lead screw 43 is fixedly connected to the output end of the second motor 42. The movable sleeve 44 is threadedly connected to the surface of the lead screw 43. The cleaning component 45 is fixedly connected to one side of the movable sleeve 44. The cleaning component 45 is located above the detection platform 1. The second motor 42 can drive the lead screw 43 to rotate, thereby driving the movable sleeve 44 and the cleaning component 45 to move horizontally along the lead screw 43.

[0030] The cleaning component 45 includes a third motor 451 and a cleaning brush 452. The third motor 451 is fixed on the movable sleeve 44, and the output end of the third motor 451 is connected to the cleaning brush 452. By controlling the third motor 451, the cleaning brush 452 can be driven to rotate, and the battery can be cleaned by the cleaning brush 452.

[0031] The sliding connection between the housing 41 and the movable sleeve 44 allows the housing 41 to limit the movement of the movable sleeve 44, providing precise guidance for its movement. This ensures the stability and accuracy of the cleaning brush 452 during the cleaning process, resulting in better cleaning performance. It effectively removes impurities from the surface of the entire lithium battery pack, improving the reliability of the test results. The cleaning component 45 adopts a design where the third motor 451 drives the cleaning brush 452. This design is simple and efficient, effectively cleaning dust and impurities from the surface of the entire lithium battery pack, creating favorable conditions for testing and enhancing the equipment's cleaning capabilities.

[0032] The lithium battery pack is fixed and flipped by the flipping and fixing mechanism 3, and the cleaning mechanism 4 cleans the surface. The two work together to facilitate comprehensive testing of the entire lithium battery pack. The overall design provides an effective test preparation method for lithium battery pack failure analysis, solves the shortcomings of traditional equipment in terms of test comprehensiveness and cleaning, and improves test efficiency and accuracy.

The air inlet grille 72 is installed on the top of the dust collection box 71, the fan 74 is installed on one side of the dust collection box 71, and the filter plate 73 is installed on the front side of the fan 74. One of the covers of the dust collection box 71 is designed to be bolted and removable to facilitate subsequent cleaning of the dust collection box 71.

[0034] The support column 5 and base plate 6 of this application provide stable support for the entire platform. At the same time, a dust removal mechanism 7 is set between the testing platform 1 and the base plate 6, which makes the equipment more structurally stable and has good dust handling capabilities, improving the working environment. The dust removal mechanism 7, through the cooperation of the air intake grille 72, filter plate 73 and fan 74, can effectively collect the dust generated during the cleaning process, prevent the dust from spreading and polluting the working environment and equipment, ensure the smooth progress of the testing work, and improve the environmental performance of the equipment.

[0035] The specific operating principle of this application is as follows: In use, the battery is placed between two fixed brackets 361. Then, the position of the fixed brackets 361 connected to the second vertical plate 32 is adjusted by the first hydraulic cylinder 34 so that the distance between the two fixed brackets 361 is adapted to the size of the battery. Then, the second hydraulic cylinder 362 drives the clamping plate 363 to move down, thereby fixing the battery between the two fixed brackets 361. After the battery is fixed, the cleaning brush 452 is driven to move horizontally by the cooperation of the second motor 42 and the lead screw 43. During this process, the third motor 451 can control the rotation of the cleaning brush 452 to achieve cleaning. The hydraulic cylinder 22 can also drive the battery to move vertically so that the cleaning brush 452 can fully contact the battery to achieve battery detection and surface cleaning. After cleaning one side of the battery, the hydraulic cylinder 22 is used to move the entire battery upward, providing sufficient space for the lithium battery pack to be flipped. Then, the first motor 33 drives the fixing frame 361 directly connected to it to flip, and the fixing frame 361 at the other end also flips, realizing the flipping of the entire lithium battery pack. Then, the other side of the battery is inspected and the surface is cleaned. Remove dust or impurities that may affect the detection. The dust collection box 71 is connected to the horizontal plate 1 through the air intake grille 72. The fan 74 works to make air enter the dust collection box 71 from the air intake grille 72, and then be discharged after being filtered by the filter plate 73. This effectively collects the dust generated during the cleaning process and keeps the working environment clean.
