Technical Field
[0001] This utility model relates to the field of battery cell testing technology, and in particular to a testing mechanism for retired battery cells. Background Technology
[0002] Among retired battery cells, some still have a certain amount of remaining capacity and performance. Through testing, screening, and reuse, resources can be effectively recycled and the environment can be sustainably developed.
[0003] In the prior art, patent document with publication number (CN218630115U) mentions a high-power lithium-ion battery cell testing mechanism, including a worktable and a placement plate. Two third sliding grooves are symmetrically formed on the upper surface of the placement plate, and a second bidirectional screw is rotatably connected between the two third sliding grooves. A third slider, threadedly connected to the second bidirectional screw, is slidably connected inside each of the two third sliding grooves, and an L-shaped plate is fixedly connected to the top of each of the two third sliders. This prior art, through its automatically adjusting testing mechanism and lithium-ion battery cell fixing mechanism, can not only automatically adjust the distance between two testing pens but also limit and fix lithium-ion battery cells of different specifications, thus enabling the testing of lithium-ion battery cells of different specifications. The dual-moving mechanism allows for the placement and fixing of another lithium-ion battery cell during testing, enabling immediate testing of another cell after the first test is completed, thereby improving work efficiency.

[0018] The embodiments of the present invention are described in detail below. Examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, but should not be construed as limiting the present invention.

[0020] This utility model provides a retired battery cell testing mechanism, including a base plate 1, a fixing mechanism, two connecting lines 2, and a display panel 3. The fixing mechanism includes a lead screw 4, two sliding plates 5, two limiting blocks 6, two threaded rods 7, two sliding blocks 8, two locking blocks 9, two round blocks 10, four protruding blocks 11, and two testing components. The testing components include a testing probe 12, a fixing plate 13, four telescopic rods 14, and four springs 15. The aforementioned solution solves the problem of the prior art, which uses two symmetrically arranged L-shaped plates to fix the battery, but the L-shaped plates can only fix square batteries, resulting in low practicality.
[0021] In this specific embodiment, the surface of the base plate 1 is provided with an opening 16. The lead screw 4 is rotatably connected to the base plate 1 and located inside the opening 16. Two limiting blocks 6 are fixedly connected to the base plate 1 and are respectively disposed on both sides of the opening 16. One side of each limiting block 6 is inclined. Two sliding plates 5 are threadedly connected to the lead screw 4 and are located between the two limiting blocks 6. The surfaces of the two sliding plates 5 are provided with sliding grooves 17. Two sliding blocks 8 are slidably connected to the corresponding sliding plates 5 and are located inside the sliding plates 5. One end of each of the two threaded rods 7 is slidably connected to the corresponding sliding block 8, and the other end of each of the two threaded rods 7 is threadedly connected to the corresponding sliding plate 5. The two detection components are respectively set on one side of the corresponding sliding block 8. When the battery is placed above the two limiting blocks 6, the screw 4 is rotated, and under the restriction of the base plate 1, the two sliding plates 5 move in opposite directions to clamp and fix the battery. When the threaded rod 7 is rotated, the threaded rod 7 drives the sliding block 8 to slide accordingly, so that the detection component is aligned with the battery. This allows for the detection of batteries of different sizes, improving practicality.
[0022] Two locking blocks 9 are fixedly connected to the lead screw 4 and are respectively disposed at both ends of the lead screw 4. Both locking blocks 9 are circular and located inside the base plate 1. Two circular blocks 10 are fixedly connected to the corresponding threaded rods 7 and are respectively disposed inside the corresponding sliding blocks 8. The locking blocks 9 fix the position of the lead screw 4, and the circular blocks 10 are locked inside the sliding blocks 8, causing the sliding blocks 8 to move accordingly.
[0023] Secondly, the four protrusions 11 are fixedly connected to the corresponding sliding blocks 8 and are respectively arranged on both sides of the corresponding sliding blocks 8. The sliding groove 17 is provided with grooves 18 on both sides. The grooves 18 are adapted to the protrusions 11. The protrusions 11 are locked inside the grooves 18. When the threaded rod 7 rotates, the sliding blocks 8 move accordingly. The protrusions 11 are locked inside the grooves 18, which improves the stability of the detection component.
[0024] Secondly, the fixing plate 13 is disposed on one side of the corresponding sliding block 8. One end of the four telescopic rods 14 is fixedly connected to the fixing plate 13, and the other end of the four telescopic rods 14 is fixedly connected to the sliding block 8. They are evenly disposed between the fixing plate 13 and the sliding block 8. The four springs 15 are respectively covered on the surface of the corresponding telescopic rods 14. The detection probe 12 is fixedly connected to the fixing plate 13 and is located on one side of the fixing plate 13. When the sliding plate 5 moves, the detection probe 12 contacts the battery and makes an electrical connection with the battery to detect the battery status. At the same time, the telescopic rods 14 retract accordingly, and the springs 15 push the fixing plate 13 to press the detection probe 12 against the battery, while preventing excessive pressure between the detection probe 12 and the battery, thus improving the detection effect and reducing the risk of damage to the detection probe 12.
[0025] In addition, the display panel 3 is fixedly connected to the base plate 1 and is located on the surface of the base plate 1. One end of the two connecting lines 2 is fixedly connected to the display panel 3, and the other end of the two connecting lines 2 passes through the sliding block 8 and is fixedly connected to the corresponding detection probe 12. The connecting lines 2 transmit electrical signals to the display panel 3, and after analysis, the battery data is displayed on the display panel 3.
[0026] When using this utility model, the battery is placed above the two limiting blocks 6. The lead screw 4 is rotated, and under the restriction of the base plate 1, the two sliding plates 5 move in opposite directions to clamp and fix the battery. The threaded rod 7 is rotated, and the threaded rod 7 drives the sliding block 8 to slide accordingly. The detection probe 12 contacts the battery and is electrically connected to the battery to detect the battery's condition. At the same time, the telescopic rod 14 retracts accordingly, and the spring 15 pushes the fixing plate 13 to press the detection probe 12 against the battery. This prevents the pressure between the detection probe 12 and the battery from becoming too high, improving the detection effect and reducing the risk of damage to the detection probe 12. The connecting line 2 transmits the electrical signal to the display panel 3, and after analysis, the battery data is displayed on the display panel 3.
[0027] The above-disclosed embodiments are merely one or more preferred embodiments of this application and should not be construed as limiting the scope of this application. Those skilled in the art can understand that all or part of the processes for implementing the above embodiments and equivalent changes made in accordance with the claims of this application still fall within the scope of this application.
