Figure 2 The diagram shown is a schematic representation of a test support frame 4 according to an embodiment of this utility model. Figure 3 The diagram shown is a schematic representation of the vertical adjustment mechanism and test support plate 5 according to an embodiment of this utility model. Figures 1 to 3 The testing mechanism includes a support platform 1, multiple sets of cell clamping support platforms 2, a test support frame 4, multiple rows of test probes 9, and a vertical adjustment assembly 6. Specifically, multiple guide rails are provided along the length of the support platform 1, and multiple sets of cell clamping support platforms 2 are slidably mounted on the guide rails and can move along the guide rails. Multiple sets of cell clamping slots 3 are provided on the cell clamping support platforms 2 to clamp the cells 8. A test support frame 4 is provided on the top of the support platform 1, and a test support plate 5 is provided on the test support frame 4. Multiple rows of test probes 9 are provided at the bottom of the test support plate 5, corresponding to the positions of the multiple sets of cell clamping slots 3, so that when the multiple sets of cell clamping slots 3 clamp the cells 8 and move them to the bottom of the test support frame 4, the electrical performance of the cells 8 can be tested. By setting multiple sets of cell clamping slots 3 on the cell clamping support platforms 2, the cell clamping support platforms 2 can be used on production lines to meet the needs of large-scale testing. A vertical adjustment component 6 is also provided on the test support frame 4, and the test support plate 5 is located at the bottom of the vertical adjustment component 6.

[0021] In this embodiment, the testing mechanism also includes a lateral adjustment component 7, which is disposed on the test support frame 4 on one side of the vertical adjustment component 6. It is used to adjust the lateral position of the test support frame 4 and the vertical adjustment component 6 to adjust the position of the test probe 9 on the test support plate 5 so that the test probe 9 corresponds to the position of the battery cell 8 held on the battery cell clamping support platform 2.

[0022] like Figure 4As shown, in this embodiment, the testing mechanism further includes a U-shaped probe mounting plate 15, disposed at the bottom of the test support plate 5.

The testing mechanism also includes a slide rail 10, disposed on the sides of the probe mounting plate 15 away from the test probes 9. The slide rail 10 is connected to the test support plate 5 so that the test support plate 5 can slide along the slide rail 10. By fixing the test probes 9 on the test support plate 5, when the probe mounting plate 15 slides along the slide rail 10, the test probes 9 fixed on the probe mounting plate 15 will slide relative to each other, thereby changing the width between the test probes 9 on the test support plate 5 and the test probes 9 on the probe mounting plate 15. This allows the sliding probe mounting plate 15 to accommodate battery cells 8 of different widths, enabling the testing of battery cells 8 of different widths.

[0023] In this embodiment, in order to enable the probe mounting plate 15 to slide along the slide rail 10, the test mechanism also includes an adjusting screw 11, which is set at the bottom of the test support plate 5 near the test probe 9.

[0025] In this embodiment, in order to accurately adjust the width between the test probes 9, the testing mechanism also includes a scale pointer 14 and a scale display scale 13. One end of the scale pointer 14 is connected to the side of the probe mounting plate 15 near the slide rail 10, and the scale display scale 13 is disposed on the side of the slide rail 10 near the scale pointer 14.

One end of the connecting rod 61 is connected to the test support plate 5, and the driving cylinder 62 is connected to the other end of the connecting rod 61 to drive the test support plate 5 to rise and fall.

[0027] In this embodiment, in order to prevent the position of the battery cell 8 from shifting during the test and affecting the test results, a battery cell clamping plate 31 corresponding to the battery cell clamping groove 3 is provided on both sides of the guide rail of each battery cell clamping support platform 2 to further fix the battery cell 8 and prevent the battery cell 8 from tilting to both sides during the test.

[0028] In this embodiment, in order to drive the vertical drive assembly and the test support plate 5 to adjust laterally, the lateral adjustment assembly 7 includes a base plate 71 and a push cylinder 72. The base plate 71 is set on the top of the test support frame 4, and the push cylinder 72 is set on the base plate 71. The drive end of the push cylinder 72 is set on one side of the vertical adjustment assembly 6, and is used to adjust the lateral position of the test support frame 4 and the vertical adjustment assembly 6.

[0029] Through the above technical solution, this utility model provides a multi-variety battery cell electrical performance testing mechanism. This testing mechanism uses multiple guide rails arranged along the length of a support platform 1, on which multiple sets of battery cell clamping support platforms 2 are slidably arranged. Each battery cell clamping support platform 2 has multiple sets of battery cell clamping slots 3 to clamp battery cells 8. A test support frame 4 is arranged at the top of the support platform 1, and a test support plate 5 is arranged on the test support frame 4. Multiple rows of test probes 9 are arranged at the bottom of the test support plate 5, corresponding to the positions of the multiple sets of battery cell clamping slots 3. When the multiple sets of battery cell clamping slots 3 move the battery cells 8 to the bottom of the test support frame 4, the electrical performance of the battery cells 8 is tested. A vertical adjustment component 6 is also arranged on the test support frame 4, and the test support plate 5 is located at the bottom of the vertical adjustment component 6. By adjusting the width between each row of test probes 9 and adjusting the lifting and lowering of the vertical adjustment component 6, it can accommodate battery cells 8 of different widths and heights.
