Description

Technical Field

[0001] This application relates to the field of battery manufacturing, specifically to a battery testing fixture and a battery testing system. Background Technology

[0002] In the research and development and production of batteries, it is necessary to conduct rapid, accurate and reliable tests on the battery's electrical performance (such as voltage, internal resistance, etc.).

[0003] In related technologies, operators typically need to manually align the test probes with the positive and negative terminals of the battery before operating testing equipment (such as an internal resistance tester or voltmeter) to test the electrical performance of the battery. This testing method is inefficient, and the inconsistent measurement points lead to measurement errors. Utility Model Content

[0004] This application provides a battery testing fixture and a battery testing system to address the problem of how to improve the efficiency and accuracy of battery electrical performance testing.

[0005] To achieve the above objectives, the embodiments of this application adopt the following technical solutions:

[0006] In a first aspect, embodiments of this application provide a battery testing fixture. The battery testing fixture includes a limiting member, a mounting member, and a positioning member. The limiting member is used to limit the position of the battery under test; the mounting member and the positioning member are located on opposite sides of the limiting member in a first direction. The mounting member has a spaced-apart first mounting portion and a second mounting portion, the first mounting portion for mounting a positive electrode probe, and the second mounting portion for mounting a negative electrode probe; at least one of the mounting member and the positioning member is slidable relative to the limiting member along the first direction to push the battery under test, causing the positive electrode of the battery under test to abut against the positive electrode probe, and the negative electrode of the battery under test to abut against the negative electrode probe.

[0007] In some possible implementations of the first aspect, the limiting member has a receiving space for accommodating the battery under test, and one end of the limiting member adjacent to the positioning member has an opening; the positioning member is slidable relative to the limiting member along a first direction, and the positioning member has a first moving position, when the positioning member is in the first moving position, at least a portion of the positioning member enters the limiting member through the opening.

[0008] In some possible implementations of the first aspect, the positioning member includes a body and a stop protrusion; the body is located outside the limiting member, and the stop protrusion is located on the body and closer to the limiting member relative to the body; when the positioning member is in the first moving position, at least a portion of the stop protrusion enters the receiving space through an opening.

[0009] In some possible implementations of the first aspect, the end of the limiting member near the mounting member has a limiting wall plate for limiting the movement of the battery under test toward the mounting member; the limiting wall plate has a clearance through hole for clearing the positive and negative electrode probes.

[0010] In some possible implementations of the first aspect, the battery testing fixture further includes a base plate and a sliding assembly. A limiting member is fixedly connected to the base plate; the sliding assembly connects the base plate and the positioning member respectively; the positioning member is slidably connected to the base plate along a first direction via the sliding assembly.

[0011] In some possible implementations of the first aspect, the sliding component includes a sliding rail and a slider that are slidably connected; one of the rail and the slider is disposed on the base plate; and the other of the rail and the slider is connected to a positioning element.

[0012] In some possible implementations of the first aspect, the base plate has a strip hole extending in a first direction, and the mounting component has an assembly hole; the assembly hole has an internal thread; the battery testing fixture also includes a fastener that passes through the strip hole and the assembly hole in sequence to connect the mounting component to the base plate.

[0013] In some possible implementations of the first aspect, the positioning member also has a second moving position; when the positioning member is in the second moving position, the positioning member and the limiting member are spaced apart along the length direction of the limiting member.

[0014] In some possible implementations of the first aspect, both the first mounting part and the second mounting part are mounting holes.

[0015] In some possible implementations of the first aspect, the mounting component includes a first sub-mounting component and a second sub-mounting component; the first sub-mounting component and the second sub-mounting component are detachably connected, and the first sub-mounting component and the second sub-mounting component cooperate to define a first mounting portion and a second mounting portion.

[0016] In some possible implementations of the first aspect, the positioning element is provided with a handle.

[0017] Secondly, embodiments of this application provide a battery testing system, which includes a test probe and a battery testing fixture. The battery testing fixture is the same as described above; the test probe is connected to the battery testing fixture.

[0018] The battery testing fixture and battery testing system provided in this application have the following beneficial effects:

[0019] By using a battery testing fixture as an interface component to connect testing equipment (such as an internal resistance tester, voltmeter, etc.) to the battery under test, the fixture's limiting component can limit the battery under test, and the mounting component can be used to mount the positive and negative electrode probes. Since at least one of the mounting component and the positioning component is slidable relative to the limiting component along a first direction, the sliding of at least one of the mounting component and the positioning component relative to the limiting component along the first direction can push the battery under test, causing the positive electrode of the battery under test to contact the positive electrode probe, and the negative electrode to contact the negative electrode probe. Then, the testing equipment can test the battery's electrical performance. During this process, due to the limiting effect of the limiting component on the battery under test and the abutment effect of the mounting component and positioning component on the battery under test, the battery under test will not be displaced. At the same time, since the positive and negative probes are mounted on the mounting component, the positive and negative probes are relatively fixed. Therefore, the problem of battery / probe jitter during the test is avoided, which helps to improve the detection efficiency of the battery under test, improve the alignment accuracy of the positive and negative terminals of the battery with the positive and negative probes, and make the detection points of each battery under test uniform, which helps to reduce detection errors and improve detection accuracy.

[0042] In the research and development and production of batteries, it is necessary to conduct rapid, accurate and reliable tests on the battery's electrical performance (such as voltage, internal resistance, etc.).

[0043] In related technologies, operators typically need to manually align the test probe with the positive and negative terminals of the battery before operating testing equipment (such as an internal resistance tester, voltmeter, etc.) to test the electrical performance of the battery under test. However, during the testing process, the operator's hands often tremble, causing displacement of the test probe / battery under test. This not only leads to low testing efficiency but also inconsistent measurement points, resulting in measurement errors.

[0044] To address the aforementioned problems, this application provides a battery testing fixture and a battery testing system. In this application, the battery testing fixture serves as an interface component connecting testing equipment (such as an internal resistance tester, voltmeter, etc.) and the battery under test. Specifically, the battery testing fixture includes a limiting member, a mounting member, and a positioning member. The limiting member can limit the position of the battery under test. The first mounting portion of the mounting member is used to mount a positive electrode probe, and the second mounting portion is used to mount a negative electrode probe. Since at least one of the mounting member and the positioning member is slidable relative to the limiting member along a first direction, the sliding of at least one of the mounting member and the positioning member relative to the limiting member along the first direction can push the battery under test, causing the positive electrode of the battery under test to contact the positive electrode probe, and the negative electrode of the battery under test to contact the negative electrode probe. Then, the testing equipment tests the electrical performance of the battery. During this process, due to the limiting effect of the limiting component on the battery under test and the abutment effect of the mounting component and positioning component on the battery under test, the battery under test will not be displaced. At the same time, since the positive and negative probes are mounted on the mounting component, the positive and negative probes are relatively fixed. Therefore, the problem of battery / probe jitter during the test is avoided, which helps to improve the detection efficiency of the battery under test, improve the alignment accuracy of the positive and negative terminals of the battery with the positive and negative probes, and make the detection points of each battery under test uniform, which helps to reduce detection errors and improve detection accuracy.

[0045] The technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings.

[0046] Please see Figure 1 and Figure 2 , Figure 1 This is a schematic diagram of the structure of the battery testing fixture 1 provided in some embodiments of this application; Figure 2 for Figure 1 The battery testing fixture 1 shown is a front view. The battery testing fixture 1 includes: a limiting member 100, a mounting member 200, and a positioning member 300.

[0047] The limiting member 100 is used to limit the battery 10 under test. The mounting member 200 and the positioning member 300 are located on both sides of the limiting member 100 in the first direction X. The mounting member 200 has a spaced-apart first mounting portion 210 and second mounting portion 220, the first mounting portion 210 is used to mount the positive electrode probe, and the second mounting portion 220 is used to mount the negative electrode probe.

[0048] For example, the limiting member 100 can limit the battery 10 under test along the first direction X (such as the length direction of the battery 10 under test) and along the second direction Y (such as the width direction of the limiting member 100). In this way, when the battery 10 under test is placed in the limiting member 100, the positive electrode of the battery 10 under test is opposite to the positive electrode probe along the first direction X, and the negative electrode of the battery 10 under test is opposite to the negative electrode probe along the first direction X.

[0049] At least one of the mounting member 200 and the positioning member 300 is slidable relative to the limiting member 100 along a first direction X. That is, the mounting member 200 is slidable relative to the limiting member 100 along the first direction X, while the positioning member 300 remains stationary; or, the positioning member 300 is slidable relative to the limiting member 100 along the first direction X, while the mounting member 200 remains stationary; or, the positioning member 300 is slidable relative to the limiting member 100 along the first direction X, and the mounting member 200 is also slidable relative to the limiting member 100 along the first direction X.

[0050] In this case, when at least one of the mounting member 200 and the positioning member 300 slides relative to the limiting member 100 along the first direction X, the battery under test 10 can be pushed so that the positive terminal of the battery under test 10 abuts against the positive probe, and the negative terminal of the battery under test 10 abuts against the negative probe. For example, the positive terminal of the battery under test 10 is located radially inside the negative terminal. Therefore, when the positive probe is opposite the positive terminal of the battery under test 10 along the first direction X, as long as the negative probe is spaced apart from the positive probe by a predetermined distance, the negative probe can be opposite the negative terminal of the battery under test 10 along the first direction X.

[0051] In this way, the limiting member 100 limits the position of the battery 10 under test, the mounting member 200 is used to mount the positive and negative electrode probes, and by sliding at least one of the mounting member 200 and the positioning member 300 relative to the limiting member 100 along the first direction X, the battery 10 under test is pushed so that the positive electrode of the battery 10 under test abuts against the positive electrode probe, and the negative electrode of the battery 10 under test abuts against the negative electrode probe. Then, the electrical performance of the battery 10 under test is tested by the testing equipment. During this process, due to the limiting effect of the limiting component 100 on the battery 10 under test and the abutting effect of the mounting component 200 and the positioning component 300 on the battery 10 under test, the battery 10 under test will not be displaced. At the same time, since the positive and negative probes are mounted on the mounting component 200, the positive and negative probes are relatively fixed. Therefore, the problem of vibration of the battery 10 under test / probes is avoided during the test, which helps to improve the detection efficiency of the battery 10 under test, improve the alignment accuracy of the positive and negative poles of the battery 10 under test and the positive and negative probes, and make the detection points of each battery 10 under test uniform, which helps to reduce detection errors and improve detection accuracy.

[0052] The structure and function of the battery testing fixture 1 will be introduced below, taking the example that the positioning member 300 can slide relative to the limiting member 100 along the first direction X.

[0053] Please see Figure 3 , Figure 3 for Figure 1 The diagram shows the structure of the limiting member 100. The limiting member 100 has a receiving space 101 for accommodating the battery 10 to be tested, and one end of the limiting member 100 adjacent to the positioning member 300 has an opening 110. The positioning member 300 has a first moving position, and when the positioning member 300 is in the first moving position, at least a portion of the positioning member 300 can enter the limiting member 100 through the opening 110.

[0054] Understandably, when the operator places the battery under test 10 into the limiting member 100, there is usually a certain distance between the positive and negative terminals of the battery under test 10 and the positive and negative probes connected to the battery testing fixture 1. In this case, since the bottom of the battery under test 10 is not covered by a protective film, in order to prevent sweat or dirt from adhering to the uncovered part of the battery under test 10, the operator cannot directly push the battery under test 10 by hand to make the positive and negative terminals of the battery under test 10 contact the positive and negative probes.

[0055] Therefore, by allowing at least a portion of the positioning member 300 to enter the limiting member 100 through the opening 110, the operator can push the positioning member 300, which in turn pushes the battery under test 10, causing the positive and negative terminals of the battery under test 10 to contact the positive and negative terminal probes, thereby completing the detection of the electrical performance of the battery under test 10. In this way, the battery under test 10 can be prevented from being contaminated during the testing process, which is beneficial to improving the reliability of the detection.

[0056] Please see Figure 4 , Figure 4 for Figure 1 The diagram shows the structure of the positioning member. The positioning member 300 includes a body 310 and a stop protrusion 320. The body 310 is located outside the limiting member 100, and the stop protrusion 320 is provided on the body 310 and is closer to the limiting member 100 than the body 310. When the positioning member 300 is in the first moving position, at least a portion of the stop protrusion 320 can enter the receiving space 101 through the opening 110.

[0057] Thus, after the battery to be tested 10 is placed into the limiting member 100, the operator can push the positioning member 300 in the first direction X so that the stop protrusion 320 enters the receiving space 101 through the opening 110. The stop protrusion 320 can push the battery to be tested 10 so that the positive and negative terminals of the battery to be tested 10 contact the positive and negative terminal probes. This structure is simple, small in size, and easy to operate, which is conducive to improving the detection efficiency of the battery to be tested.

[0058] In some embodiments, the positioning member 300 also has a second movable position. When the positioning member 300 is in the second movable position, the positioning member 300 is spaced apart from the limiting member 100 along the length direction of the limiting member 100. This facilitates the operator to insert the battery under test 10 into the limiting member 100 or to remove the battery under test 100 from the limiting member 100, thereby improving testing efficiency.

[0059] It should be noted that the first and second movement positions mentioned in some embodiments of this application are not the endpoint positions of the positioning member 300 moving along the first direction X. For example, when the positioning member 300 moves to the first movement position along the first direction X, the positioning member 300 can continue to move along the first direction X toward the direction closer to the mounting member 200. As another example, when the positioning member 300 moves to the second movement position along the first direction X, the positioning member 300 can continue to move along the first direction X toward the direction away from the mounting member 200. In this way, the battery testing fixture 1 can be used to test the electrical performance of batteries with larger or smaller dimensions, thereby improving the applicability of the battery testing fixture 1.

[0060] In some embodiments, see Figure 1 The positioning member 300 has a handle portion 330. The handle portion 330 is provided on the body 310. In this way, the operator can easily push the positioning member 300 to slide (such as sliding between the first movement position and the second movement position) by holding the handle portion 330, which helps to improve the efficiency of detection.

[0061] In some embodiments, the handle portion 330 may also be provided on the stop protrusion 320, which is not limited in this application.

[0062] In some embodiments, see Figures 1 to 3 The limiting member 100 has a limiting wall plate 130 at one end near the mounting member 200, which is used to limit the movement of the battery under test 10 toward the mounting member 200. The limiting wall plate 130 has a clearance through hole 131, which is used to avoid the positive electrode probe and the negative electrode probe.

[0063] In this way, the ends of the positive and negative probes can be located in the receiving space 101 through the clearance through hole 131. When the battery under test 10 moves along the first direction X to abut against the limiting wall plate 130, the positive and negative electrodes of the battery under test 10 can contact the positive and negative probes respectively. This avoids the positive and negative electrodes of the battery under test 10 only contacting the positive and negative probes, causing the positive and negative probes to be deformed or damaged due to excessive force. This is beneficial to improving the durability of the battery testing fixture 1 and the probes, and improving the reliability of the test.

[0064] In some embodiments, see Figures 1 to 3The limiting member 100 has limiting side plates 120 at both ends along the second direction Y. The two limiting side plates 120 can limit the battery under test 10 in the second direction Y to prevent the battery under test 10 from rolling along the second direction Y, thereby limiting the battery under test 10 to a predetermined position, which helps to improve the consistency of the detection points of multiple batteries under test and improve the detection accuracy.

[0065] The limiting side plate 120 has a clearance groove 121. The clearance groove 121 is open on the Y-axis side to avoid the operator's fingers. It is understood that after testing the battery 10, the operator needs to remove the battery 10 from the limiting member 100. However, the bottom of the battery 10 is not covered by a protective film, making it inconvenient for the operator to remove the battery through the open opening 110. Therefore, by providing the clearance groove 121 in the limiting side plate 120, the operator can pinch the side of the battery 10 covered by the protective film to remove the battery 10 from the limiting member 100, thereby improving the efficiency of the test.

[0066] Please see Figure 5 , Figure 5 for Figure 1 The schematic diagram of the base plate 400 shown indicates that the battery testing fixture 1 also includes the base plate 400. The limiting member 100 is fixedly connected to the base plate 400.

[0067] For example, see Figure 3 and Figure 5 The limiting member 100 has a first threaded hole 140. The base plate 400 has a second threaded hole 430 corresponding to the first threaded hole 140. By passing fasteners (such as screws) through the first threaded hole 140 and the corresponding second threaded hole 430, the limiting member 100 and the base plate 400 can be fixedly connected.

[0068] It should be noted that some embodiments of this application do not limit the number of the first threaded hole 140 and the second threaded hole 430. For example, there can be two (illustrated as two first threaded holes 140 in the figure), three or more, and the number of the second threaded holes 430 corresponds to the number of the first threaded holes 140. This helps to improve the reliability of the connection between the limiting member 100 and the base plate 400.

[0069] In some embodiments, see Figure 1 and Figure 2The battery testing fixture 1 also includes a sliding assembly 500. The sliding assembly 500 is connected to the base plate 400 and the positioning member 300. The positioning member 300 is slidably connected to the base plate 400 along a first direction X via the sliding assembly 500. Thus, the positioning member 300 can slide relative to the limiting member 100 via the sliding assembly 500 and the base plate 400. The base plate 400 can support the limiting member 100, the mounting member 200, and the positioning member 300, thereby forming the battery testing fixture 1 into a whole, which is beneficial to improving the stability and reliability of battery testing.

[0070] In some embodiments, see Figure 5 The bottom of the base plate 400 has at least one counterweight 420 to increase the weight of the base plate 400. Thus, when the positioning member 300 slides relative to the base plate 400 through the sliding component 500, the counterweight 420 can prevent the base plate 400 from shifting under the action of the positioning member 300, thereby improving the stability of the base plate 400 and the stability of the sliding fit between the positioning member 300 and the base plate 400.

[0071] In some embodiments, see Figure 1 and Figure 2 The sliding assembly 500 includes a sliding rail 510 and a slider 520 that are slidably connected; one of the slide rail 510 and the slider 520 is disposed on the base plate 400; the other of the slide rail 510 and the slider 520 is connected to the positioning member 300. It can be understood that the sliding assembly composed of the slide rail 510 and the slider 520 has a simple structure, high reliability of fit, and low cost.

[0072] In some embodiments, there is a damping force between the slide rail 510 and the slider 520. For example, a damping material is provided between the slide rail 510 and the slider 520, or the portion of the slide rail 510 that is slidably connected to the slider 520 is provided with a damping structure, or the portion of the slider 520 that is slidably connected to the slide rail 510 is provided with a damping structure. This application does not limit this.

[0073] Thus, when the operator pushes the positioning component 300 to the first moving position, the positioning component 300 can remain in the first moving position, which makes it convenient for the operator to operate the testing equipment to measure the electrical performance of the battery 10 under test, thereby improving the efficiency of the test.

[0074] The following will describe the sliding assembly 500 with the slide rail 510 disposed on the base plate 400 and the slider 520 connected to the positioning member 300 as an example. Some embodiments of this application are not limited thereto.

[0075] See Figure 1 and Figure 5The slide rail 510 has a third threaded hole 511. The base plate 400 has a fourth threaded hole 440 corresponding to the third threaded hole 511. By passing fasteners (such as screws) through the third threaded hole 511 and the corresponding fourth threaded hole 440, the slide rail 510 and the base plate 400 can be fixedly connected.

[0076] It should be noted that some embodiments of this application do not limit the number of the third threaded hole 511 and the fourth threaded hole 440. For example, there may be two, three or more third threaded holes 511, and the number of fourth threaded holes 440 corresponds to the number of third threaded holes 511 (the figure shows four fourth threaded holes 440). This is beneficial to improving the reliability of the connection between the slide rail 510 and the base plate 400.

[0077] See Figure 1 and Figure 4 The slider 520 has a fifth threaded hole (not shown in the figure). The body 310 has a sixth threaded hole 311 corresponding to the fifth threaded hole. By passing fasteners (such as screws) through the fifth threaded hole and the corresponding sixth threaded hole 311, the slider 520 and the body 310 can be fixedly connected.

[0078] It should be noted that some embodiments of this application do not limit the number of the fifth threaded hole and the sixth threaded hole 311. For example, there can be two, three or more fifth threaded holes, and the number of sixth threaded holes 311 corresponds to the number of fifth threaded holes (four sixth threaded holes 311 are shown in the figure). This is beneficial to improving the reliability of the connection between the slider 520 and the body 310.

[0079] In some embodiments, see Figure 5 The base plate 400 has a strip-shaped hole 410 extending along a first direction X, and the mounting member 200 has a mounting hole (not shown) with internal threads. The battery testing fixture 1 also includes a fastener that passes through the strip-shaped hole 410 and the mounting hole in sequence to connect the mounting member 200 to the base plate 400 (e.g., a detachable connection). The mounting hole can be a through hole or a blind hole, and this application does not limit this.

[0080] It is understandable that the strip hole 410 extends along the first direction X. When fasteners are used to connect the strip hole 410 and the mounting hole, the relative position of the mounting hole and the strip hole 410 can be adjusted to adjust the relative position of the mounting part 200 and the limiting part 100. This allows the relative position of the probe and the limiting part 100 to be adjusted, so that the battery testing fixture 1 can adapt to batteries and probes of different sizes and models, which is beneficial to improving the versatility of the battery testing fixture 1.

[0081] In some embodiments, see Figure 1Both the first mounting portion 210 and the second mounting portion 220 are mounting holes. This facilitates the installation of the positive electrode probe into the first mounting portion 210 and the installation of the negative electrode probe into the second mounting portion 220.

[0082] Please see Figure 6 and Figure 7 , Figure 6 for Figure 1 The diagram shows the structure of the first sub-mount component. Figure 7 for Figure 1 The diagram shows the structure of the second sub-mounting member. Mounting member 200 includes a first sub-mounting member 230 and a second sub-mounting member 240. The first sub-mounting member 230 and the second sub-mounting member 240 are detachably connected. The first sub-mounting member 230 and the second sub-mounting member 240 cooperate to define a first mounting portion 210 and a second mounting portion 220.

[0083] Thus, the mounting component 200 can be divided into a first sub-mounting component 230 and a second sub-mounting component 240, and the first sub-mounting component 230 and the second sub-mounting component 240 can be processed simultaneously, which helps to improve the production efficiency of the mounting component 200.

[0084] In some embodiments, see Figure 6 and Figure 7 The first sub-mount 230 has a first sub-mount portion 231 and a second sub-mount portion 232. The second sub-mount 240 has a third sub-mount portion 241 and a fourth sub-mount portion 242. The first sub-mount portion 231, the second sub-mount portion 232, the third sub-mount portion 241, and the fourth sub-mount portion 242 are all semi-holes. The first sub-mount portion 231 and the third sub-mount portion 241 cooperate to define the first mounting portion 210, and the second sub-mount portion 232 and the fourth sub-mount portion 242 cooperate to define the second mounting portion 220. This allows the first mounting portion 210 and the second mounting portion 220 to accommodate probes of different sizes (e.g., radial dimensions), and facilitates the removal and installation of the probes.

[0085] In some embodiments, see Figure 6 and Figure 7 The first sub-mount 230 has a seventh threaded hole 233. The second sub-mount 240 has an eighth threaded hole (not shown in the figure) corresponding to the seventh threaded hole 233. By passing fasteners (such as screws) through the seventh threaded hole 233 and the corresponding eighth threaded hole, the first sub-mount 230 and the second sub-mount 240 can be fixedly connected.

[0086] It should be noted that some embodiments of this application do not limit the number of the seventh threaded hole 233 and the eighth threaded hole. For example, there can be two seventh threaded holes 233, with one seventh threaded hole 233 at each end of the first sub-mount member 230 extending in the third direction Z. The number of eighth threaded holes corresponds to the number of seventh threaded holes 233, which helps to improve the reliability of the connection between the first sub-mount member 230 and the body 310. Alternatively, there can be three or more seventh threaded holes 233 and eighth threaded holes, which is not limited in this application.
