These tabs are then connected to the wires or clamps of the testing equipment to complete the electrical performance test. However, this approach has many significant drawbacks. The process of welding the tabs is time-consuming. From the preparation and positioning of the tabs to the actual welding operation, each step increases the testing cycle, reduces testing efficiency, and consequently, reduces overall production efficiency.

[0004] Based on the above analysis, this utility model aims to provide an electrical performance testing platform suitable for different types of steel-cased batteries, in order to solve the problem of low testing efficiency in the method of welding tabs on the positive and negative electrodes of steel-cased batteries.

[0005] The purpose of this utility model is mainly achieved through the following technical solutions.

[0007] Base;

[0008] A frame assembly is mounted on the base;

[0009] A sliding rod is provided on the frame device and is capable of sliding on the frame device;

[0010] A fixing clamp is provided on the base to clamp the steel-cased battery and is movable on the base;

[0011] A conductive rod is slidably mounted on a sliding rod and connected between the battery tabs and the testing equipment to enable electrical performance testing.

[0012] Furthermore, the conductive rod includes an insulating sleeve and a conductive core, with the insulating sleeve wrapping around the outside of the conductive core.

[0013] Furthermore, one end of the conductive core is cylindrical, and the other end is sheet-like, wherein the cylindrical end is connected to the battery tab, and the sheet-like end is connected to the testing equipment.

[0014] Furthermore, the electrical performance testing platform applicable to different types of steel-cased batteries also includes a conductive rod sliding assembly. The conductive rod sliding assembly includes a first ring and a second ring fixedly disposed on the first ring. The central axis direction of the first ring is perpendicular to the central axis direction of the second ring. The first ring is sleeved on the sliding rod to slide on the sliding rod, and the second ring is sleeved on the conductive rod to move the conductive rod on the second ring.

[0015] Furthermore, the conductive rod sliding assembly also includes a first positioning bolt, and the first ring and the second ring are provided with a first positioning screw hole. The first positioning bolt can cooperate with the first positioning screw hole to fix the first ring on the sliding rod and the conductive rod on the second ring.

[0016] Furthermore, the fixing fixture includes a sliding groove, a fixture body, a second positioning bolt, and a second positioning screw hole. The sliding groove is embedded in the base, the fixture body is installed in the sliding groove and can move within the sliding groove, the second positioning bolt passes through the fixture body, and the second positioning screw hole is formed in the sliding groove. The second positioning bolt and the second positioning screw hole are used to fix the fixture body.

[0017] Furthermore, the sliding rod includes a sliding rod body and sliding sleeves disposed at both ends of the sliding rod body, the sliding sleeves being slidably fitted onto the frame device.

[0021] Compared with the prior art, the present invention can achieve at least one of the following beneficial effects:

[0022] (1) The electrical performance testing platform for different types of steel-cased batteries described in this utility model allows the battery to be placed on the base surface during testing. The clamping position is adjusted by moving the fixed clamp to adapt to the shape of the battery. The sliding rod moves along the frame device to the corresponding battery tab area. The conductive rod slides along the sliding rod to the contact position with the tab. The end of the conductive rod is connected to the test equipment wire to form a closed test circuit. When changing to different types of batteries, only the position of the fixed clamp and the contact point of the conductive rod need to be readjusted. No welding operation is required to complete the test preparation. Traditional solutions rely on welding processes to establish electrical connections. Each battery test requires welding and disassembly of the tab, which is time-consuming and the tab cannot be reused. This solution uses a movable conductive rod to directly contact the tab and uses a multi-directional adjustment mechanism to achieve positioning, eliminating the impact of welding tabs on test efficiency. It realizes the rapid establishment and disassembly of electrical connections during the testing of steel-cased batteries, avoids the time consumption of welding processes, shortens the single test cycle, and improves the testing efficiency of the production line.

The orthogonal arrangement of the first ring and the second ring forms a two-dimensional adjustment mechanism. When the position of the battery tab is different in the horizontal and vertical dimensions, the conductive rod can be adjusted in both directions at the same time to ensure reliable connection of the electrode contact surface. Thus, the problem of poor contact caused by the limited adjustment of the conductive rod position is solved.

Detailed Implementation

[0033] The preferred embodiments of the present invention will now be described in detail with reference to the accompanying drawings, which constitute a part of the present invention and are used together with the embodiments of the present invention to illustrate the principles of the present invention, but are not intended to limit the scope of the present invention.

[0034] Example 1

[0035] like Figure 1 As shown, this embodiment provides an electrical performance testing platform suitable for different types of steel-cased batteries, including: a base 1; a frame device 2, disposed on the base 1; a sliding rod 3, disposed on the frame device 2 and capable of sliding on the frame device 2; a fixing clamp 4, disposed on the base 1 to clamp the steel-cased battery and capable of moving on the base 1; and a conductive rod 5, slidably disposed on the sliding rod 3, and the conductive rod 5 is connected between the battery tabs and the testing equipment to realize electrical performance testing.

[0036] The base 1, serving as a support structure for other components, can be formed from sheet metal, providing an installation foundation for the frame device 2, sliding rod 3, and fixing clamp 4. The frame device 2 refers to the support structure vertically mounted on the base 1, used to support the sliding rod 3 and define its movement path. The sliding rod 3 is a guide component on the frame device 2, providing lateral movement freedom for the conductive rod 5. The fixing clamp 4 is a positioning device with clamping function, used to fix steel-cased batteries of different sizes. The conductive rod is a conductive component connecting the battery tabs to the testing equipment, its function being to establish a reliable electrical connection while avoiding short-circuit risks. During testing, the battery is placed on the surface of the base 1, and the clamping position is adjusted by moving the fixing clamp 4 to adapt to the battery shape. The sliding rod 3 moves along the frame device 2 to the corresponding battery tab area, and the conductive rod 5 moves along the sliding rod. Rod 3 slides to the contact position with the tab, and the end of conductive rod 5 connects to the test equipment wires to form a closed test circuit. When changing to different battery models, only the position of the fixing fixture 4 and the contact point of conductive rod 5 need to be readjusted. Test preparation can be completed without welding. Compared with existing technologies, traditional solutions rely on welding to establish electrical connections. Each battery test requires welding and disassembly of the tab, which is time-consuming and the tabs cannot be reused. This solution uses the movable conductive rod 5 to directly contact the tab and uses a multi-directional adjustment mechanism to achieve positioning, eliminating the impact of welding tabs on test efficiency. It realizes the rapid establishment and disassembly of electrical connections during the testing of steel-cased batteries, avoiding the time consumption of welding. When changing to different battery models, testers can quickly adapt the equipment through mechanical adjustment, shorten the single test cycle, and improve the testing efficiency of the production line.

[0037] A preferred embodiment of this utility model is as follows: Figure 2 As shown, the conductive rod 5 includes an insulating sleeve 51 and a conductive core 52, with the insulating sleeve 51 wrapping around the outside of the conductive core 52.

[0038] The insulating sleeve 51 can be made of rubber or polyvinyl chloride material, which is used to isolate the conductive core 52 from the external environment; the conductive core 52 refers to the metal component used to transmit current, which can be made of copper or aluminum material, and is used to form an electrical connection with the battery tabs and testing equipment to conduct electrical signals. Through the composite structure of the insulating sleeve 51 and the conductive core 52, the safety protection of the conductive component is achieved without the use of welding tabs, and the safety risks caused by the exposed conductive rod are solved.

[0039] Based on this, one end of the conductive core 52 is cylindrical and the other end is sheet-shaped. The cylindrical end is connected to the battery tab, and the sheet-shaped end is connected to the testing equipment.

[0040] Compared with existing technologies, traditional solutions require welding tabs onto the battery tabs to achieve electrical connection. The welding process is time-consuming and may damage the battery surface. By adapting the shape of the conductive core 52, the cylindrical end and the sheet end can be directly matched with the battery tabs and the test equipment, respectively, eliminating the welding step, shortening the test preparation time, and avoiding the heat effects or mechanical damage introduced by the welding operation, thus improving the test efficiency.

[0041] A preferred embodiment of this utility model is as follows: Figure 3 As shown, the electrical performance testing platform applicable to different models of steel-cased batteries also includes a conductive rod sliding assembly 6. The conductive rod sliding assembly 6 includes a first ring 61 and a second ring 62 fixedly disposed on the first ring 61. The central axis direction of the first ring 61 is perpendicular to the central axis direction of the second ring 62. The first ring 61 is sleeved on the sliding rod 3 to slide on the sliding rod 3, and the second ring 62 is sleeved on the conductive rod 5 to move the conductive rod 5 on the second ring 62.

[0042] The conductive rod sliding assembly 6, through the axial displacement of the first ring 61 along the sliding rod 3, drives the conductive rod 5 to adjust its position as a whole, adapting to the differences in the tab spacing of different battery models. The sleeve structure between the second ring 62 and the conductive rod 5 allows the conductive rod 5 to extend and retract along its own axis, realizing dynamic adjustment of the contact pressure with the battery tabs. The orthogonal arrangement of the first ring 61 and the second ring 62 forms a two-dimensional adjustment mechanism. When there are differences in the position of the battery tabs in both the lateral and longitudinal dimensions, the conductive rod 5 can be adjusted in both directions simultaneously, ensuring reliable connection of the electrode contact surfaces. This solves the problem of poor contact caused by the limited position adjustment of the conductive rod 5, and achieves adaptive matching of the tab positions of steel-cased batteries of different sizes. The conductive rod 5 can move laterally along the sliding rod 3 to adjust the tab spacing, and at the same time, adjust the contact pressure through longitudinal extension and retraction, ensuring the stability of current conduction during testing.

[0043] A preferred embodiment of this utility model is as follows: Figure 3 As shown, the conductive rod sliding assembly 6 also includes a first positioning bolt 63, and a first positioning screw hole 64 is provided on the first ring 61 and the second ring 62. The first positioning bolt 63 can cooperate with the first positioning screw hole 64 to fix the first ring 61 on the sliding rod 3 and the conductive rod 5 on the second ring 62.

[0044] Specifically, when the conductive rod 5 moves axially along the sliding rod 3 to the target position, the first ring 61 is threadedly locked to the sliding rod 3 by the first positioning bolt 63, preventing relative displacement between the first ring 61 and the sliding rod 3. When the conductive rod 5 is radially adjusted along the second ring 62 to the position of contact with the battery tab, the second ring 62 is threadedly locked to the conductive rod by the first positioning bolt 63, eliminating the gap between the conductive rod 5 and the second ring 62. Thus, the problem of poor contact caused by the inability to quickly position the conductive rod 5 during the test is solved. Stable electrical contact between the conductive rod 5 and the battery tab is ensured by mechanical locking, improving connection stability.

[0045] A preferred embodiment of this utility model is as follows: Figure 4 As shown, the sliding rod 3 includes a sliding rod body 31 and sliding sleeves 32 fixedly disposed at both ends of the sliding rod body 31. The sliding sleeves 32 are slidably sleeved on the frame device 2.

[0046] When testing different types of steel-cased batteries, the sliding sleeve 32 moves along the frame device 2, causing the sliding rod body 31 to rise and fall as a whole, so that the contact end of the conductive rod 5 is precisely aligned with the battery tab. In the horizontal direction, the sliding rod body 31 moves synchronously through the sliding sleeves at both ends, which can adjust the position of the conductive rod 5 relative to the fixed clamp 4 laterally to adapt to the tab spacing of batteries of different sizes. Through the sliding fit structure between the sliding sleeve 32 and the frame device 2, the sliding rod body 31 has bidirectional adjustability, eliminating the tab contact deviation caused by battery size differences and avoiding repeated disassembly or welding operations.

[0047] In a preferred embodiment of the present invention, the sliding rod 3 further includes a locking component, which is used to position the sliding sleeve 32 on the frame device 2.

[0048] When the sliding sleeve 32 slides along the frame device 2 to the target position, the locking assembly applies radial pressure to the sliding sleeve 32 by tightening the thread or squeezing the clamping block. The pressure causes friction between the inner wall of the sliding sleeve 32 and the surface of the frame device 2, thereby restricting the movement of the sliding sleeve 32. At this time, the conductive rod 5 is kept in a fixed position by the sliding rod 3 to ensure stable contact pressure with the battery tab and avoid poor contact or fluctuations in test data caused by the displacement of the sliding sleeve.

[0049] A preferred embodiment of this utility model is as follows: Figure 1 As shown, the frame device 2 includes a vertical connecting rod 21 and a horizontal connecting rod 22. The vertical connecting rod 21 is fixedly mounted on the base 1, and the horizontal connecting rod 22 is fixedly mounted on the vertical connecting rod 21.

[0050] The vertical connecting rod 21 is a support structure that is perpendicular to the base 1. It can be fixed to the base 1 by welding or bolting to establish the vertical support foundation of the frame device 2. The horizontal connecting rod 22 is a support structure that extends horizontally. It can be fixed to the vertical connecting rod 21 by welding or bolting to form the horizontal support surface of the frame device 2 and expand the installation and adjustment range of the sliding rod 3.

[0051] Example 2

[0052] A preferred embodiment of this utility model is as follows: Figure 5 As shown, the fixing fixture 4 includes a sliding groove 41, a fixture body 42, a second positioning bolt 43, and a second positioning screw hole 44. The sliding groove 41 is embedded in the base 1, the fixture body 42 is installed in the sliding groove 41 and can move within the sliding groove 41, the second positioning bolt 43 passes through the fixture body 42, and the second positioning screw hole 44 is opened in the sliding groove 41. The second positioning bolt 43 can cooperate with the second positioning screw hole 44 to fix the fixture body 42.

[0053] As an improvement, the through hole on the fixture body 42 can be a strip-shaped through hole, allowing the second positioning bolt 43 to move in position thereon.

[0054] During actual testing, the fixture body 42 is embedded in the sliding groove 41 through the bottom protrusion and slides freely in a straight line within the sliding groove 41. When the steel-cased battery is placed on the base, the fixture body 42 is pushed to a position that abuts against the side of the battery casing. At this time, the second positioning bolt 43 passes through the through hole in the side wall of the fixture body 42 and is screwed into the second positioning screw hole 44 aligned with the sliding groove 41. Through the axial pressure generated by the thread engagement, the fixture body is pressed against the inner wall of the sliding groove, forming a rigid fixation. The guiding effect of the sliding groove 41 allows the fixture body 42 to move only in one direction, avoiding deviation caused by external forces during testing. Thus, the problem of limited fixture position adjustment and unstable fixation during steel-cased battery testing is solved, realizing continuous position adjustment of the fixture along the sliding groove. The threaded locking mechanism ensures clamping stability, adapting to the clamping requirements of different battery specifications and improving testing efficiency.

[0055] Based on this, multiple second positioning screw holes 44 are provided, and the second positioning screw holes 44 are arranged at equal intervals on the sliding groove 41.

[0056] During the movement of the fixture body 42 within the sliding groove 41, the operator can select the corresponding position of the second positioning screw hole 44 according to the size of the battery being tested. The second positioning bolt 43 is used to clamp and fix the fixture by engaging with the selected screw hole. The equally spaced screw hole layout ensures that the displacement of the fixture is adjusted in a fixed step size each time, avoiding positional deviations caused by differences in screw hole spacing.

[0057] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any changes or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in the present utility model should be included within the protection scope of the present utility model.
