Description

[0002] In the field of lithium battery manufacturing, with the continuous advancement of battery cell production technology and the diversification of market demand, the size of battery cells is becoming increasingly diverse, which places higher compatibility and flexibility requirements on lithium battery testing equipment. Traditional testing equipment is often designed based on fixed-size battery cells for testing. The spacing between the probe assembly and the negative pressure cup assembly is fixed, which makes it difficult to adapt to the frequent changes in battery cell size. When it is necessary to change to test battery cells of different widths, the traditional practice is to adjust the position of the probe assembly or the negative pressure cup assembly through manual or semi-manual operation to adapt to the new battery cell size specifications. However, this adjustment method is not only time-consuming and labor-intensive, significantly increasing production costs, but also leads to a decrease in production efficiency, greatly limiting the automation level and production efficiency of the testing equipment. In addition, due to the limitations of accuracy and stability in the adjustment process, traditional equipment often produces large errors when testing battery cells of different sizes, which in turn affects the quality and consistency of the product.

[0041] See also Figures 1 to 6 The present invention provides an automatic type change test device, comprising:

[0042] A support frame 10 is provided with a top frame 11, and a receiving cavity 12 is formed between the top frame 11 and the support frame 10, providing a stable installation environment for internal components. A lifting frame 13 is movably provided in the receiving cavity 12, and a battery cell tray 14 is placed on the lifting frame 13. The battery cell tray 14 can move synchronously with the lifting frame 13, so as to facilitate the rapid positioning and testing of the battery cells.

[0043] The first driving member 15 is used to provide a stable and controllable driving force for the lifting and lowering movement of the lifting frame 13, ensuring that the battery cell tray 14 can be accurately lifted to a predetermined position.

[0044] The first transmission wheel set 20 is arranged on the top frame 11 and is connected to the top frame 11 through the first synchronous belt 21, thereby ensuring the accuracy and reliability of power transmission.

[0045] The second transmission wheel set 30 is also provided on the top frame 11 , cooperates with the first transmission wheel set 20 , and is connected to the first transmission wheel set 20 through a second synchronous belt 31 , further enhancing the flexibility and adaptability of the device.

Multiple probe modules 40 all include a probe assembly 41, a negative pressure assembly 42 and a module separation frame 43. The integrated design of these components makes the test process more efficient and accurate. The probe assembly 41 and the negative pressure assembly 42 are both slidably mounted on the top frame 11 through a hanger 44. This sliding installation method allows the probe module 40 to flexibly adjust its position to adapt to battery cells of different sizes. The probe assembly 41 and the negative pressure assembly 42 both include an integrated strip 45. The module separation frame 43 is slidably mounted on the integrated strip 45 and is located between the hanger 44 and the integrated strip 45.

[0048] The third driving member 60 , serving as a power source for the second transmission wheel assembly 30 , is used to provide driving force for the second transmission wheel assembly 30 , ensuring that the negative pressure integrated member 42 can move synchronously and stably, thereby meeting the test requirements.

[0049] Specifically, through the coordinated linkage of the first synchronous belt 21 and the second synchronous belt 31, the probe assembly 41 and the negative pressure assembly 42 of each probe module 40 can be adjusted synchronously, adapting to the testing requirements of different battery cell widths, improving production testing efficiency, and reducing costs.
