[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0022] Reference Figures 1-3 A flexible lithium battery capacity testing device includes a frame 1, which has at least one testing station. The frame 1 is equipped with a positioning component 23, a second support plate 17, and a vertical clamp 19 at the testing station. The positioning component 23 can limit the position of the battery to be tested. The vertical clamp 19 has a pressure rod 24 that can move up and down. The pressure rod 24 can drive the second support plate 17 to move up and down. At least two probe components 2 are installed on the second support plate 17. The probe components 2 are connected to the electrical testing equipment through cables.

[0023] When the battery under test is placed, it is first fixed by the positioning component 23 to ensure its stable position in the testing station. The vertical clamp 19 is equipped with a pressure rod 24 that can move up and down. When the pressure rod 24 moves downward, it drives the second support plate 17 to move downward in the vertical direction. The probe assembly 2 mounted on the second support plate 17 moves downward accordingly and contacts the terminal of the battery under test, thereby forming a conductive path. The probe assembly 2 is connected to the electrical testing equipment through a cable, and the electrical testing equipment can then perform performance tests such as capacity tests on the battery under test. When the pressure rod 24 moves upward, the second support plate 17 moves upward, the probe assembly 2 detaches from the battery surface, the circuit is broken, and the test process is completed.

[0024] The frame 1 is equipped with a positioning component 23, a second support plate 17, and a vertical clamp 19 at the testing station. A pressure rod 24 drives the second support plate 17 to move the probe assembly 2 up and down, enabling the probe assembly 2 to achieve controllable contact and separation from the battery under test. This allows capacity testing to be completed without welding the battery terminals. This solution is simple to operate, highly efficient, avoids battery scrapping caused by welding, and significantly improves the flexibility and practicality of the testing device.

[0025] The probe assembly 2 includes an adjustment plate 16, which has a third slot 18 along the length of the battery to be tested. The adjustment plate 16 is locked to the second support plate 17 by bolts passing through the third slot 18. A conductive head 13 is mounted on the adjustment plate 16 and is connected to the electrical testing equipment via a cable. The top of the conductive head 13 is equipped with the adjustment plate 16 in an adjustable manner via bolts and nuts 27. A first support plate 14 is fixedly mounted on the conductive head 13. A vertically arranged second guide rod 15 is fixedly connected to the first support plate 14. A second guide sleeve 26 is fixedly mounted on the adjustment plate 16. The second guide rod 15 passes through the second guide sleeve 26 and the two are slidably connected.

[0026] The adjusting plate 16 is bolted through the third slot 18 and locked to the second support plate 17, allowing for fine-tuning of its length. A conductive head 13 is mounted on the adjusting plate 16 and electrically connected to the electrical testing equipment via a cable. The top of the conductive head 13 is vertically adjustable to the adjusting plate 16 via bolts and nuts 27, allowing for fine-tuning of its height. A first support plate 14 is fixedly mounted on the conductive head 13, with a vertically mounted second guide rod 15 fixedly attached to it. A second guide sleeve 26 is fixedly mounted on the adjusting plate 16, with the second guide rod 15 passing through and slidingly connected to it, thus providing guidance and limiting during the vertical adjustment of the conductive head 13. Adjustment of the third slot 18 allows for fine-tuning of the left-right position of the adjusting plate 16; adjustment of the bolts and nuts 27 allows for fine-tuning of the vertical position of the conductive head 13, ensuring that the conductive head 13 accurately presses against the target contact position of the battery under test. This allows the conductive head 13 to be adjustable in both vertical and horizontal directions. This structure can adapt to batteries of different sizes and terminal positions, achieving flexible positioning and contact. It not only ensures reliable conductivity during testing but also avoids the need for fixture replacement due to differences in battery models, significantly improving the applicability and efficiency of the testing device.

[0027] The vertical clamp 19 is fixedly connected to the support base 20. The support base 20 has a vertical fourth slot 25. The support base 20 is locked to the frame 1 by bolts passing through the fourth slot 25. The support base 20 is fixedly connected to the adjusting bolt 21. The frame 1 is fixedly connected to the support block 22. The adjusting bolt 21 is assembled with the support block 22 in an adjustable manner through the nut.

[0028] Alternatively, the vertical clamp 19 is fixedly connected to a support base 20, the support base 20 is provided with a vertical fourth slot 25, the support base 20 is locked to the frame 1 by bolts passing through the fourth slot 25, the support base 20 is threadedly connected to an adjusting bolt 21, the frame 1 is fixedly connected to a support block 22, and the top of the adjusting bolt 21 is matched with the support block 22 for limiting.

[0029] The vertical clamp 19 is fixedly connected to a support base 20. The support base 20 has a vertical fourth slot 25. The support base 20 is bolted through the fourth slot 25 and locked to the frame 1, allowing the support base 20 to be adjusted vertically along the fourth slot 25. An adjusting bolt 21 is fixedly connected to the support base 20, and a support block 22 is fixedly connected to the frame 1. The adjusting bolt 21 is vertically adjustable to the support block 22 via a nut, thereby adjusting the height of the vertical clamp 19. Alternatively, the support base 20 is threadedly connected to the adjusting bolt 21, and the frame 1 is fixedly connected to the support block 22. The top of the adjusting bolt 21 engages with the support block 22 for a limiting fit. Rotating the adjusting bolt 21 allows for fine-tuning of the support base 20 and the vertical clamp 19 along the height direction. This allows for fine-tuning of the vertical clamp 19's position based on the different heights of the batteries being tested or the installation differences at different workstations, avoiding poor clamping due to battery specifications and improving the adaptability and adjustment flexibility of the device.

[0030] The frame 1 is fixedly installed with a vertically arranged first guide rod 3, and the second support plate 17 is vertically slidably engaged with the first guide rod 3.

[0031] The second support plate 17 is fixedly connected to a vertically arranged first guide sleeve 4. The first guide sleeve 4 is slidably connected to the first guide rod 3. The first guide rod 3 is located below the first guide sleeve 4 and is equipped with a positioning block 6 that can be adjusted up and down. A thrust spring 5 is installed between the top of the positioning block 6 and the bottom of the first guide sleeve 4.

[0032] A vertically oriented first guide rod 3 is fixedly mounted on the frame 1. A second support plate 17 slides vertically with the first guide rod 3, ensuring stable vertical movement of the second support plate 17. A vertically oriented first guide sleeve 4 is fixedly connected to the second support plate 17, and the first guide sleeve 4 slides with the first guide rod 3, providing guidance and support for the second support plate 17 during vertical movement. A vertically adjustable positioning block 6 is installed below the first guide rod 3 and the first guide sleeve 4. A thrust spring 5 is installed between the top of the positioning block 6 and the bottom of the first guide sleeve 4. The thrust spring 5 stores elastic force when the second support plate 17 is compressed downwards, and releases the elastic force when the second support plate 17 is raised, thereby achieving an upward reset function. This allows the second support plate 17 to quickly return to its original position after clamping, facilitating the placement of new batteries to be tested.

[0033] The positioning component 23 includes two parallel and spaced second positioning blocks 12, and a first positioning block 8 is provided between one end of the two second positioning blocks 12. The length direction of the battery to be tested is respectively abutted against one of the second positioning blocks 12, and one side of the width direction is abutted against the first positioning block 8.

[0034] The second positioning block 12 is provided with a second slot 11 along the width direction of the battery to be tested. The second positioning block 12 is locked to the frame 1 by bolts passing through the second slot 11.

[0035] And / or the first positioning block 8 is provided with a first slot 9 along the length direction of the battery to be tested, and the first positioning block 8 is locked to the frame 1 by bolts passing through the first slot 9.

[0037] When the battery under test is placed at the testing station, its two sides along its length abut against a second positioning block 12, and its side along its width abuts against a first positioning block 8, thus achieving three-sided positioning. The second positioning block 12 has a second slot 11 arranged along the width direction of the battery under test. The second positioning block 12 is locked to the frame 1 by bolts passing through the second slot 11, thus allowing for position adjustment in the width direction. The first positioning block 8 has a first slot 9 arranged along the length direction of the battery under test. The first positioning block 8 is locked to the frame 1 by bolts passing through the first slot 9, thus allowing for position adjustment in the length direction. Through the cooperation of the second slot 11 and the first slot 9, the positioning assembly 23 can flexibly adjust the limiting space to accommodate batteries of different sizes and specifications under test.
