The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, and should not be construed as limiting the present invention.

[0021] A preferred embodiment of the fixture for battery cell testing provided by this utility model is, for example... Figure 1-5 As shown: A fixture for battery cell testing includes a mounting plate 21, a clamping mechanism 2 located at the bottom of the mounting plate 21, two sets of conductive clamping plates 22 mounted on the top surface of the mounting plate 21, namely conductive clamping plate A and conductive clamping plate B, and a clamping area on the conductive clamping plate 22, wherein the clamping mechanism 2 is located in the clamping area, namely clamping area A and four clamping areas B; a pad is provided in the clamping area, namely pad A241 and pad B242, which are respectively installed in clamping area A and clamping area B, and a battery cell 29 is placed above the pad; a stop plate A231 and two side baffles A251 are installed in clamping area A, and a stop plate B232 and a side baffle B252 are installed in clamping area B; a limit buffer bracket 26 is installed on the right side of the mounting plate 21, and a limit buffer 27 is installed on the limit buffer bracket 26 to limit the movement range of the test battery cell and provide a certain buffering effect;

[0022] The clamping mechanism includes vertical positioning cylinders 31 correspondingly disposed in clamping area A and clamping area B. The vertical positioning cylinders 31 are installed at the bottom of the mounting plate 21. The piston rod end of the vertical positioning cylinder 31 located in clamping area A is provided with a positioning head A32, while the piston rod end of the vertical positioning cylinder 31 located in clamping area B is provided with a positioning head B33. The positioning head A32 and positioning head B33 are positioned by the extension and retraction of the cylinder, so as to achieve precise clamping of the battery cell.

[0023] The clamping mechanism 2 includes a transverse positioning cylinder 34 installed on the bottom left side of the mounting plate 21. A drive block 35 is fixedly installed at the end of the piston rod of the transverse positioning cylinder 34. A clamp foot 36 is integrally connected to one end of the drive block 35. A guide rail 37 is connected to the top of the drive block 35. A guide rail slider 38 is slidably connected to the guide rail 37. The guide rail slider 38 is fixed to the bottom of the mounting plate 21. A clamp arm 39 is fixed to the clamp foot 36. A positioning block is installed on the top of the clamp arm 39. The positioning block is divided into positioning block A310 and positioning block B311. A guide block 312 is installed at the bottom of both positioning block A310 and positioning block B311.

[0024] Compression springs 28 are provided between the positioning block and the side baffle A251, the side baffle B252, and the limit buffer bracket 26, respectively, to provide positioning force. The compression spring 28 between the positioning block A310 and the side baffle A251 ensures that the battery cell is correctly aligned in the clamping area A, while the compression spring 28 between the positioning block B311 and the side baffle B252 ensures that the battery cell is accurately positioned in the clamping area B.

[0025] During use, the battery cells are pre-placed on their respective pads. During the operation of clamping mechanism one, the extension and retraction of the vertical positioning cylinder 31 drives positioning heads A32 and B33 to precisely clamp the battery cells. During the operation of clamping mechanism two, when the horizontal positioning cylinder 34 pushes the drive block 35, the clamping feet 36 drive the clamping arms 39 to move. The clamping arms 39, through the sliding of the guide block 312, precisely move positioning blocks A310 and B311 to the designated positions, achieving stable clamping of the battery cell 29. After the clamping arms 39 reach the designated position, the compression spring 28 immediately generates pressure, ensuring that the battery cell 29 is firmly fixed in the predetermined position, thereby maintaining stability during the testing process.

[0026] In summary, by rationally configuring clamping mechanisms one and two, along with the compression spring 28, the position and clamping force of the battery cell can be precisely controlled during performance testing. This improves the accuracy and repeatability of the tests, ensuring a more scientific and objective performance evaluation. During continuous testing, these mechanisms work together to provide a stable working environment for the battery cell, reducing performance data deviations caused by improper operation or clamping errors. Ultimately, this allows for more stringent quality control of the battery cell products, meeting the ever-growing market demands.
