[0002] Lithium-ion batteries possess outstanding advantages such as high energy density, low environmental pollution, high power density, long lifespan, wide applicability, and low self-discharge coefficient. They are among the most widely used batteries in the world today and a crucial component of new energy development. A lithium-ion battery cell is assembled from positive electrode sheets, negative electrode sheets, and a separator through winding or stacking to form an electrode assembly, which is then housed in a casing and filled with electrolyte.

[0003] In the production of battery cells, the formation and capacity testing of the cells is a crucial step. After formation and capacity testing, to ensure the quality of the produced cells, they need to be probed to check their formation and capacity testing quality. However, in existing production lines, when the number of battery cells undergoing batch formation and capacity testing changes, the formation and capacity testing needle bed needs to be changed. This requires the battery cell probing device to adjust the number and position of its probe components according to the number and position of battery cells in the tray to meet the batch testing requirements. However, the existing battery cell probing devices require a long operation time during the changeover process and have a low degree of automation, thus reducing the probing efficiency of battery cells and hindering the improvement of production efficiency.

[0026] The technical solutions in the embodiments of this utility model will be clearly and completely described below. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0027] like Figure 1-4 As shown, a press-type telescopic probe includes a connecting seat 1, a telescopic component 2, a resetting component 3, and a probe rod 4. The connecting seat 1 is sleeved on the telescopic component 2 and the resetting component 3, and the connecting seat 1 is slidably connected to the telescopic component 2. The telescopic component 2 and the resetting component 3 are engaged with each other. The resetting component 3 rotates circumferentially around the probe rod 4 within the connecting seat 1. The probe rod 4 passes through the telescopic component 2 and is slidably connected to it vertically. A probe needle 41 passes through the probe rod 4. By utilizing the engaged telescopic component 2 and the resetting component 3, the circumferential rotation of the resetting component 3 guides the telescopic component 2 to slide up and down reciprocally within the connecting seat 1, synchronously driving the probe rod 4 and the probe needle 41 within the telescopic component 2, thereby realizing the change of the probe's detection position.

[0028] Furthermore, the inner wall of the connecting seat 1 is provided with a first sliding groove 11 and a second sliding groove 12 spaced apart in the circumferential direction, the outer wall of the telescopic member 2 is provided with a guide block 21 that is engaged in the first sliding groove 11 and the second sliding groove 12 in the circumferential direction, the reset member 3 is provided with an angled protrusion 31, the front end of the first sliding groove 11 is provided with a first inclined surface 13, the front end of the second sliding groove 12 is provided with a second inclined surface 14, the depth of the first sliding groove 11 is the same as the thickness of the angled protrusion 31, the depth of the second sliding groove 12 is the same as the thickness of the guide block 21, and the depth of the first sliding groove 11 is greater than the depth of the second sliding groove 12. Guided by the guide block 21, the telescopic member 2 can slide up and down in the connecting seat 1. The telescopic member 2 can slide in the connecting seat 1 by switching the circumferential rotation of the beveled protrusion 31 of the reset member 3 on the first inclined surface 13 and the second inclined surface 14. When the beveled protrusion 31 is pushed outward by the guide block 21 and slides to the first inclined surface 13, the beveled protrusion 31 slides into the first groove 11 and pushes the guide block 21 in the first groove 11 to slide towards the bottom end of the first groove 11, causing the telescopic member 2 and its connected probe 41 to be pushed outward of the connecting seat 1.

[0029] When the angled protrusion 31 is pushed outward again by the guide block 21 and slides to the second inclined surface 14, the angled protrusion 31 is stuck on the outside of the second slide groove 12. Because the thickness of the angled protrusion 31 is greater than the depth of the second slide groove 12, the angled protrusion 31 cannot enter the second slide groove 12. Therefore, the telescopic member 2 and its connected probe 41 remain on the inside of the connecting seat 1. The detection position of the probe 41 is switched through the above conversion.

[0030] Furthermore, a first elastic element 15 is provided between the connecting seat 1 and the telescopic member 2. The first elastic element 15 is sleeved on the outer wall of the telescopic member 2, and its two ends abut against the connecting seat 1 and the telescopic member 2, respectively. The first elastic element 15 is a compression spring, which pushes the telescopic member 2 outward.

[0031] Furthermore, the telescopic member 2 is provided with a protruding ring 22, which abuts against the first elastic member 15. The protruding ring 22 defines the compression range of the first elastic member 15.

[0032] Furthermore, a gasket 23 is provided between the convex ring 22 and the first elastic member 15 to protect the convex ring 22 and prevent the first elastic member 15 from damaging the convex ring 22 during cyclic compression and relaxation.

[0033] Furthermore, a fixing member 42 is threadedly connected to the probe rod 4, and the fixing member 42 abuts against the convex ring 22. The fixing member 42 limits the extension position of the telescopic member 2. The position can be adjusted by rotating the threaded fixing member 42. A second elastic member 44 is provided between the probe head 43 and the reset member 3, and the two ends of the second elastic member 44 abut against the probe head 43 and the reset member 3 respectively.

[0034] Furthermore, the probe rod 4 is provided with a probe head 43, which is threadedly connected to the probe rod 4, and the probe needle 41 passes through the probe head 43 and the probe rod 4.

[0035] Furthermore, the probe 41 is externally provided with a first insulating member 45, a second insulating member 46, and a third insulating member 47. The first insulating member 45 is located on the probe head 43, the second insulating member 46 is located in the middle of the probe 41, and the third insulating member 47 is located at the junction of the probe 41 and the probe rod 4. This isolates the probe 41 from direct contact with other components, ensuring the accuracy of the detection results.

[0036] Furthermore, a third elastic element 48 is provided between the first insulating element 45 and the second insulating element 46, with both ends of the third elastic element 48 abutting against the first insulating element 45 and the second insulating element 46, respectively. This third elastic element 48 is a tension spring, which controls the probe 41 and its connected telescopic element 2 to retract inward in the connecting seat 1, thereby realizing the extension and retraction of the probe 41.

[0037] Furthermore, the connector 1 is provided with a connecting through hole 16. This allows the connector 1 to be fixed to the corresponding testing equipment.

[0038] Based on the disclosure and teachings of the above specification, those skilled in the art can make changes and modifications to the above embodiments. Therefore, this utility model is not limited to the specific embodiments described above, and any obvious improvements, substitutions, or modifications made by those skilled in the art based on this utility model are within the protection scope of this utility model. Furthermore, although some specific terms are used in this specification, these terms are only for convenience of explanation and do not constitute any limitation on this utility model.
