Description

Technical Field

[0001] This utility model relates to the field of battery testing technology, and in particular to a short-circuit testing fixture. Background Technology

[0002] Short-circuit testing during battery cell production is a crucial method for ensuring battery safety. By simulating short-circuit scenarios that might occur during cell manufacturing, battery products with potential safety hazards can be screened out, preventing them from entering the market and thus protecting consumers' lives and property. Furthermore, short-circuit testing can also detect foreign particles or impurities inside the cell. These foreign objects could cause short circuits during normal use, potentially leading to safety accidents.

[0003] A battery cell generally consists of a cell body and two tabs. Due to different usage scenarios, the arrangement of the tabs varies. In some battery cells, the two tabs are connected to the two ends of the cell body respectively. Figure 1 As shown), in some other cells, the two tabs are connected to the same side of the cell. Figure 2 (As shown).

[0004] In existing technologies, short-circuit testing fixtures for battery cells are only used for testing one type of battery cell and cannot be adapted to battery cells with two different tab arrangements. Furthermore, the simulation of battery short-circuit behavior by existing short-circuit testing fixtures is relatively limited and cannot simulate short-circuit behavior under different conditions. Therefore, existing short-circuit testing fixtures have many problems and cannot meet the requirements for short-circuit detection under multiple conditions.

[0005] Therefore, there is an urgent need to design a short-circuit test fixture to solve the above problems. Utility Model Content

[0042] The utility model will be further explained in detail below in combination with the drawings and embodiments. It can be understood that the specific embodiments described here are only used to explain the utility model, and not limit the utility model. In addition, it needs to be explained that in order to facilitate the description, only the part related to the utility model is shown in the drawings, not all structures.

[0043] In the description of the utility model, unless otherwise explicitly specified and limited, the terms "connected", "connected", "fixed" should be understood broadly, for example, can be fixedly connected, can be detachably connected, or integrated, can be mechanically connected, can be electrically connected, can be directly connected, can be indirectly connected through the intermediate medium, can be the internal communication of two elements or the interaction relationship of two elements. For ordinary skilled in the art, the specific meaning of the above terms in the utility model can be understood according to the specific circumstances.

[0044] In this invention, unless otherwise explicitly specified and limited, "above" or "below" the second feature can include direct contact between the first and second features, or contact between the first and second features through another feature between them. Furthermore, "above," "over," and "on top" of the second feature includes the first feature directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature includes the first feature directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.

[0045] In the description of this embodiment, the terms "upper," "lower," "left," and "right," etc., refer to the orientation or positional relationship shown in the accompanying drawings. They are used only for ease of description and simplification of operation, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model. In addition, the terms "first" and "second" are only used for distinction in description and have no special meaning.

[0046] This embodiment provides a short-circuit testing fixture that is compatible with battery cells 800 of different sizes with the same tab arrangement, as well as battery cells 800 with different tab arrangements, thus having higher adaptability. It also increases the simulation of battery short-circuit behavior under different conditions, meeting the short-circuit detection requirements under multiple conditions.

[0047] like Figure 3 As shown, the short-circuit test fixture includes a pressing mechanism 10, a supporting mechanism 20, and a driving mechanism (not shown in the figure). The supporting mechanism 20 is used to support the battery cell 800; the pressing mechanism is located three times the distance from the supporting mechanism. Figure 3 On one side (in the Z direction), there are a connecting assembly 11, a detection assembly, and a pressure plate assembly 14; the connecting assembly 11 in the first direction ( Figure 3 (Central X direction), Second direction ( Figure 3 The ends of the device (which are perpendicular to each other in the Y direction, X direction, and Y and Z directions) are all equipped with detection components in adjustable positions. The pressure plate assembly 14 is connected to the side of the connecting assembly 11 facing the bearing mechanism 20. The output end of the drive mechanism is connected to the pressing mechanism 10, which is used to drive the pressing mechanism to reciprocate along the third direction so that the pressure plate assembly 14 can press on the battery cell 800 of the bearing mechanism 20 and make the detection components contact the positive and negative terminals of the battery cell 800 to realize the pressure detection of the battery cell 800.

[0048] With the above configuration, detection components are positioned adjustable in all directions on the connecting assembly 11, improving the tooling's compatibility with different battery models. A pressure plate assembly 14 is also included, enabling pressure-applied short-circuit testing of the battery cell 800 to simulate short-circuit behavior under different battery conditions, thus improving battery safety. Through this configuration, while performing short-circuit testing, the pressure plate assembly 14 applies pressure to the battery cell body 810, allowing observation of the cell 800's performance under pressure. Pressure-applied short-circuit testing is crucial for battery safety assessment, performance optimization, and fault prevention, thereby meeting the short-circuit detection requirements under various conditions.

[0049] Specifically, the detection components are divided into a first detection component 12 and a second detection component 13. A first detection component 12 is connected to each end of the connecting component 11 in the first direction, and two second detection components 13 are respectively provided at each end of the connecting component 11 in the second direction. The two second detection components 13 connected to the same side of the connecting component 11 are spaced apart in the second direction. Both the first detection component 12 and the second detection component 13 are detachably connected to the connecting component 11 or have adjustable height. The bearing mechanism 20 includes a bearing plate 21, a second limiting member 23, and two first limiting members 22. Both first limiting members 22 are connected to the bearing plate 21 and are connected to the two first detection components 12. In a corresponding configuration, the second limiting member 23 is connected to the support plate 21 and extends along the first direction. The second limiting member 23 is located below the two second detection components 13. The battery cell 800 can be placed on the support plate 21 and simultaneously limited by the second limiting member 23 and the two first limiting members 22. The two tabs 820 of the battery cell 800 can be attached to the two first limiting members 22 or to the second limiting member 23. The connecting component 11 is connected to the output end of the driving mechanism. The driving mechanism can drive the connecting component 11 to reciprocate along a third direction so that the two first detection components 12 respectively abut against the two tabs 820 or so that the two second detection components 13 respectively abut against the two tabs 820.

[0050] It should be noted that the second limiting member 23 should be located below the second detection component 13. In order to better show the structure of the second limiting member 23, the second detection component 13 is shown in front of the view in the figure. In fact, the second detection component 13 should be behind the view in the figure.

[0051] The aforementioned short-circuit test fixture, when the battery cell 800 is tested, has one long side of the battery cell body 810 abutting against the second limiting member 23 and being limited, and the two short sides abutting against the two first limiting members 22 and being limited, respectively. When the battery cell 800 is... Figure 1When the battery cell 800 is in the specified configuration, the two tabs 820 are respectively mounted on the two first limiting members 22. The two second detection components 13 are removed or raised to avoid collision. The drive mechanism drives the pressing mechanism 10 to descend as a whole, and the two first detection components 12 respectively abut against the two tabs 820 for short circuit testing. Figure 2 When the battery cell 800 is in the same configuration, both tabs 820 are mounted on the second limiting member 23. The first detection component 12 is removed or raised to avoid collisions. The drive mechanism drives the pressing mechanism 10 to descend as a whole. The two second detection components 13 are respectively attached to the two tabs 820 for short circuit testing. Therefore, this short circuit testing fixture can realize short circuit testing of different configurations of battery cells 800, greatly improving adaptability.

[0052] The drive mechanism can be any drive element capable of outputting linear motion, such as a linear motor, linear module, or cylinder, and is not limited here.

[0053] Optionally, the distance between the two first detection components 12 in the first direction is adjustable, and the distance between the two first limiting members 22 in the first direction is also adjustable. Thus, when Figure 1 By changing the length of the battery cell 800, adjusting the spacing between the two first detection components 12, and adjusting the spacing between the two first limiting components 22, the desired result can be achieved. Figure 1 Short circuit test of 800 cells of different styles and lengths.

[0054] Optionally, such as Figure 3 As shown, the connecting assembly 11 includes a first connecting member 111 and two second connecting members 112. The first connecting member 111 is connected to the output end of the drive mechanism. The two second connecting members 112 are spaced apart and connected to the lower side of the first connecting member 111 along a first direction. The position of each second connecting member 112 relative to the first connecting member 111 in the first direction is adjustable. The first detection assembly 12 is connected to the second connecting member 112 in a one-to-one correspondence. The adjustable spacing between the two first detection assemblies 12 is achieved by adjusting the spacing between the two second connecting members 112.

[0055] The following is combined Figure 3 The structure for achieving adjustable spacing between the two first detection components 12 is described below, such as... Figure 3 As shown, the first connector 111 has a first strip-shaped hole 1111 extending along a first direction. A first locking member and a second connector 112 are correspondingly provided. The first locking member (not shown in the figure) passes through the first strip-shaped hole 1111 and is threadedly connected to the second connector 112. For example, the first locking member is a bolt. When the bolt is tightened, the position of the second connector 112 is fixed. When the bolt is loosened, the position of the second connector 112 can be adjusted along the direction of the first strip-shaped hole 1111 until the spacing between the two first detection components 12 meets the requirements of the new-sized battery cell 800.

[0056] Combination Figure 3 The structure for achieving adjustable spacing between the two first limiting members 22 is described below, such as... Figure 3 As shown, the first limiting member 22 has a fifth strip-shaped hole 221 extending along the first direction. The fifth locking member passes through the fifth strip-shaped hole 221 and is threadedly connected to the bearing plate 21. The fifth locking member can be a bolt. With the above arrangement, when the battery cell 800 is... Figure 1 When the bolt is tightened, the position of the first limiting member 22 is fixed. When the bolt is loosened, the position of the first limiting member 22 can be adjusted along the direction of the fifth strip hole 221. The distance between the two first limiting members 22 is adapted to the length of the battery cell body 810.

[0057] Optionally, such as Figure 3 As shown, the first detection component 12 includes a first mounting member 121 and a first probe 122. The first mounting member 121 is connected to a corresponding second connector 112 and its position relative to the second connector 112 is adjustable in a second direction. The first probe 122 is height-adjustably connected to the first mounting member 121 or detachably connected to the first mounting member 121. With the above configuration, when... Figure 1 When the position of the tab 820 of the battery cell 800 changes in the second direction, it can be adapted by adjusting the position of the first mounting member 121.

[0058] Furthermore, the first mounting member 121 has a second slotted hole 1211, and the second locking member passes through the second slotted hole 1211 and is threadedly connected to the corresponding second connecting member 112. The second locking member can be a bolt. When the bolt is tightened, the position of the first mounting member 121 is fixed. When the bolt is loosened, the position of the first mounting member 121 can be adjusted along the direction of the second slotted hole 1211 until the positions of the first detection member 122 and the electrode tab 820 are aligned.

[0059] Optionally, such as Figure 3 As shown, the connecting assembly 11 also includes a third connector 113. The third locking member passes through the first slot 1111 and is threadedly connected to the third connector 113. Both second detection assemblies 13 are connected to the third connector 113. With the above arrangement, the first slot 1111 can be used for connecting the two second connectors 112 and for installing the third connector 113, and both can be detached.

[0060] Optionally, the spacing between the two second detection components 13 in the first direction is adjustable. Thus, when Figure 2 The length of the battery cell 800 changes, and the distance between the two first limiting members 22 can be adjusted to achieve this. Figure 2 Short circuit test of 800 cells of different styles and lengths.

[0061] Optionally, such as Figure 3As shown, the second detection component 13 includes a second mounting member 131 and a second probe 132. The second mounting member 131 is connected to the third connector 113 and its position relative to the third connector 113 is adjustable in a first direction. The second probe 132 is height-adjustably connected to the second mounting member 131 or detachably connected to the second mounting member 131. With the above settings, when the battery cell 800 is... Figure 2 If the spacing between the two tabs 820 changes, the spacing between the two second mounting pieces 131 can be adjusted.

[0062] Furthermore, the second mounting member 131 has a fourth strip-shaped hole 1311 extending along the second direction. The fourth locking member passes through the fourth strip-shaped hole 1311 and is threadedly connected to the third connecting member 113. The fourth locking member can be a bolt. When the bolt is tightened, the position of the second mounting member 131 is fixed. When the bolt is loosened, the position of the second mounting member 131 can be adjusted along the direction of the fourth strip-shaped hole 1311 until the spacing between the two second detection members 132 and the two tabs 820 is matched.

[0063] Taking the first detector 122 as an example, the height of the first detector 122 relative to the first mounting component 121 is adjustable or detachable.

[0064] For example, the first probe 122 has an external thread, and the nut engages with the external thread and abuts against the first mounting member 121. When the nut is loosened, the height of the first probe 122 can be adjusted to prevent the first probe 122 from being damaged when it is not in use.

[0065] In other embodiments, the first detector 122 can also be detachably connected to the first mounting member 121 via a snap-fit, which will not be described in detail here. The connection relationship between the second detector 132 and the second mounting member 131 is the same as the connection relationship between the first detector 122 and the first mounting member 121, which will not be described in detail here.

[0066] Optionally, the first probe 122 and the second probe 132 can be probes or any other form that can form an electrical connection with the tab 820, and are not limited here.

[0067] Optionally, such as Figure 3 As shown, the second limiting member 23 is integrally formed with the support plate 21 and protrudes from the support plate 21, serving to limit one side of the battery cell body 810 and to limit the position of the battery cell 800. Figure 2 In terms of style, it supports the function of the 820 pole.

[0068] Optionally, the pressure plate assembly 14 and the connecting assembly 11 are detachable. This allows for the replacement of pressure plate assemblies 14 of different heights to achieve pressurization operations on battery cells 800 of different thicknesses.

[0069] Optionally, the pressure plate assembly 14 includes a connecting rod 141 and a pressure plate 142. The connecting rod 141 is connected between the first connecting member 111 and the pressure plate 142. Both ends of the connecting rod 141 are detachably connected to the first connecting member 111 and the pressure plate 142, respectively. Thus, the height of the pressure plate assembly 14 can be adjusted by replacing connecting rods 141 of different lengths, and materials are readily available. Optionally, both ends of the connecting rod 141 can be detachably connected to the first connecting member 111 and the pressure plate 142 by bolts.

[0070] Optionally, a heating element is provided on the pressure plate 142 to heat and pressurize the battery cell 800, thereby simulating short-circuit behavior of the battery under more conditions and helping to improve battery safety. Specifically, the heating element can be embedded in the pressure plate 142, and the pressure plate 142 heats the battery cell 800 through heat conduction. The heating element can also be located on the side of the pressure plate 142 facing the battery cell 800, so that it directly contacts the battery cell 800 when pressed, thereby heating the battery cell 800.

[0071] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating the present utility model, and are not intended to limit the implementation of the present utility model. Those skilled in the art can make various obvious changes, readjustments, and substitutions without departing from the protection scope of this utility model. It is neither necessary nor possible to exhaustively describe all embodiments here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this utility model should be included within the protection scope of the claims of this utility model.
