Description

Technical Field

[0001] This utility model relates to the field of positioning fixture technology, specifically to a positioning fixture for battery needle penetration testing. Background Technology

[0002] With batteries widely used in mobile devices, power tools, and electric vehicles, battery safety testing is becoming increasingly necessary. Currently, the nail penetration test is widely used for battery safety testing, and it is a critical and common testing technique. Traditional nail penetration positioning devices require manual adjustment of the test needle height, careful confirmation of the sample battery's penetration position, and equipment reset before each test. This repetitive and complex process significantly reduces testing efficiency. Improper adjustment of the test needle height can lead to inaccurate testing, and incorrect confirmation of the sample battery's position can directly damage the battery structure and even cause safety accidents.

[0003] In view of this, there is an urgent need to provide a technical solution to the above problems. Utility Model Content

[0004] The purpose of this utility model is to provide a battery needle penetration test positioning fixture that is accurate in positioning and suitable for batch testing, in order to address the shortcomings of the existing technology.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A battery needle penetration test positioning fixture includes an X-axis adjustment mechanism and a Y-axis adjustment mechanism adjustablely connected to the X-axis adjustment mechanism. The Y-axis adjustment mechanism is fixed on a needle penetration test machine. The X-axis adjustment mechanism is connected to a positioning mechanism for positioning the battery. The positioning mechanism includes a positioning plate, a stepped portion disposed at the end of the positioning plate and assembled with the X-axis adjustment mechanism, and a fixing component for fixing the positioning plate to the X-axis adjustment mechanism. The positioning plate has at least one positioning edge that matches and positions the battery.

[0007] This invention has at least the following technical advantages: The fixture of this invention is equipped with X-axis and Y-axis adjustment mechanisms, and the Y-axis adjustment mechanism is fixed on the testing machine, which can accurately adjust the Y-axis battery testing position. The X-axis adjustment mechanism is also equipped with a positioning mechanism, which can accurately adjust the battery testing position in the X-axis direction. This invention has a simple structure, precise positioning, and eliminates the need for repeated readjustment, thus meeting the needs of rapid battery safety performance testing on large-scale production lines and reducing the possibility of battery damage or safety accidents caused by adjustment errors.

[0008] As an improvement to the battery needle penetration test positioning fixture of this utility model, the X-axis adjustment mechanism includes a first adjustment plate and a first adjustment groove penetrating through the thickness direction of the first adjustment plate. The positioning plate is fixed to the first adjustment plate through the first adjustment groove by the fixing component. The adjustment mechanism can improve the accuracy of adjusting the X-axis position and is easy to operate.

[0009] As an improvement to the battery needle penetration test positioning fixture of this utility model, the positioning edge is a straight line structure, an arc structure, or a wavy line structure. When the battery to be tested is square, a straight line positioning edge is adopted. This can construct a right-angled part for positioning, so as to achieve accurate positioning of square batteries; when the battery shape is irregular, different shapes of positioning edges can be set according to different battery shapes, increasing the range of battery models that the fixture can position.

[0010] As an improvement to the battery needle penetration test positioning fixture of this utility model, the Y-axis adjustment mechanism includes a second adjustment plate, a receiving part disposed at the end of the second adjustment plate, and a second adjustment groove penetrating through the thickness direction of the second adjustment plate. The second adjustment plate is assembled and fixed to the first adjustment plate through the receiving part. This design connects the X-axis adjustment mechanism and the Y-axis adjustment mechanism into a whole, allowing simultaneous adjustment of both the X-axis adjustment component and the Y-axis adjustment mechanism in both directions, greatly simplifying the position adjustment steps and improving positioning efficiency.

[0011] As an improvement to the battery needle penetration test positioning fixture of this utility model, the second adjusting plate is assembled perpendicularly to the first adjusting plate. The second adjusting plate and the first adjusting plate are perpendicular to each other, which facilitates adjustment to the required position and improves the positioning accuracy of the fixture.

[0012] As an improvement to the battery needle penetration test positioning fixture of this utility model, it also includes a fixed seat connected to the second adjusting plate. The fixed seat includes a base, an adjusting rod, and an adjusting nut. One end of the adjusting rod is fixed to the base, and the other end of the adjusting rod passes through the second adjusting groove and is connected to the adjusting nut. This design supports the X-axis adjustment mechanism and the Y-axis adjustment mechanism together to adjust the position in two directions. By flexibly adjusting the distance between the second adjusting plate and the test platform, the positioning process for batteries of different thicknesses and sizes can be completed.

[0013] As an improvement to the battery needle penetration test positioning fixture of this utility model, the base is a magnetic base or the base has a built-in magnet. The magnetic base can firmly attract the base to the work platform, ensuring the stability of the test and reducing the error in adjustment caused by shaking.

[0014] As an improvement to the battery needle penetration test positioning fixture of this utility model, the number of fixed seats is at least two. One end of each fixed seat is connected to the second adjusting plate, and the other end is fixedly connected to the needle penetration test machine. Obviously, by supporting the X-axis adjustment mechanism and the Y-axis adjustment mechanism together on the fixed seats, the volume of the positioning mechanism is reduced; and the support effect of at least two fixed seats on the entire fixture is more robust.

[0015] As an improvement to the battery needle penetration test positioning fixture of this utility model, the needle penetration test machine includes a working platform, a lifting and moving mechanism mounted on the working platform, and a test needle slidably disposed on the top of the lifting and moving mechanism. The battery to be tested is positioned on the working platform by the positioning mechanism, and the test needle corresponds to the battery. When the fixture is adjusted to the correct position, the vertical position can be adjusted by the lifting and moving mechanism, eliminating the need for repeated height adjustments of the fixture. This design is suitable for batch positioning and testing of a batch of batteries of the same size. Attached Figure Description

[0023] The present invention will be further described in detail below with reference to the accompanying drawings, but this is not intended to limit the present invention.

[0024] Please refer to Figures 1 to 2 The battery needle penetration test positioning fixture of the present invention will now be described.

[0025] This application provides a battery needle penetration test positioning fixture, including an X-axis adjustment mechanism 1 and a Y-axis adjustment mechanism 2 that is movably connected to the X-axis adjustment mechanism 1 along the Y-axis. The Y-axis adjustment mechanism 2 is fixed on the needle penetration test machine 8 to support the Y-axis adjustment mechanism 2 and the X-axis adjustment mechanism 1. The two are held together as a whole in the same plane for position adjustment. The X-axis adjustment mechanism 1 is connected to a positioning mechanism 3 for positioning the battery. The positioning mechanism 3 includes a positioning plate 31, a stepped portion 32 disposed at the end of the positioning plate 31 near the first adjustment plate 11 for assembly with the X-axis adjustment mechanism 1, and a fixing component 33 for fixing the aforementioned positioning plate 31 to the X-axis adjustment mechanism 1. The positioning plate 31 has at least one positioning edge 311 that matches and positions the battery.

[0026] The positioning edge 311 of the positioning mechanism 3 can be set according to the shape of different batteries, as long as it can quickly match the battery to be tested to achieve positioning.

[0027] The X-axis adjustment mechanism 1 can be fixedly connected to the Y-axis adjustment mechanism 2 using fasteners (screws, bolts, etc.). After adjusting the battery testing position, the position is fixed, ensuring that the fixed points for testing batteries in the same batch are identical, thus improving the centrality and accuracy of the test data. Alternatively, the X-axis and Y-axis adjustment mechanisms can be connected via intermediate mechanisms. These intermediate mechanisms can be electrically connected to the control system to adjust the positions of the X-axis and Y-axis adjustment mechanisms 2, greatly improving the flexibility of adjustment.

[0028] Please continue to refer to this. Figure 1-2 In another embodiment of this application, the X-axis adjustment mechanism 1 includes a first adjustment plate 11 and a first adjustment groove 12 extending through the thickness direction of the first adjustment plate 11. A positioning plate 31 is fixed to the first adjustment plate 11 via a fixing assembly 33 passing through the first adjustment groove 12. When adjusting the position of the Y-axis adjustment mechanism 2, the X-axis adjustment mechanism 1 is moved back and forth along the first adjustment groove 12; when adjusting the position of the X-axis adjustment mechanism 1, the positioning mechanism 3 is moved left and right along the second adjustment groove 23. This embodiment ensures that the X-axis and Y-axis adjustment trajectories are a straight line, further improving the accuracy of the adjustment points of the test fixture.

[0029] The step portion 32 of this application is assembled with the first adjustment plate 11, which makes it easier for the battery to be tested to be fixed in a fixed position, thus achieving a better positioning effect.

[0030] In another embodiment of this application, the positioning edge 311 is a straight structure; the shape of this positioning edge 311 can better match the placement position of the square battery.

[0031] In some embodiments, the positioning edge 311 is an arc structure or a wavy structure. By designing the positioning edge 311 structure differently, it can be adapted to the positioning of various other irregularly shaped batteries.

[0032] In another embodiment of this application, the first adjusting plate 11 has at least one contact edge 111. When the positioning edge 311 is a straight structure, the positioning edge 311 is perpendicular to the contact edge 111. The contact edge 111 refers to a contact edge that contacts the battery when positioning the battery. The positioning edge 311 with a straight structure has a straight contact edge 111, which can be perpendicular to the X-direction adjusting mechanism 1 to form a right-angle structure. In this way, for the positioning of square batteries, the battery can be placed exactly in the position of the right-angle structure, achieving accurate positioning of the square battery and preventing errors caused by gaps between the battery and the positioning mechanism 3.

[0033] In another embodiment of this application, the Y-axis adjustment mechanism 2 includes a second adjustment plate 21, a receiving portion 22 disposed at the end of the second adjustment plate 21, and a second adjustment groove 23 penetrating through the thickness direction of the second adjustment plate 21. The receiving portion 22 is stepped, perfectly matching the thickness of the first adjustment plate 11, allowing the second adjustment plate 21 to be assembled and fixed to the first adjustment plate 11 via the receiving portion 22. This design ensures a perfectly stable assembly, enhancing the overall structural stability during operation. Moving the aforementioned first adjustment plate 11 to adjust the position of the Y-axis adjustment mechanism 2 simplifies the traditional steps of adjusting the position of a battery testing mechanism, making adjustments more convenient for operators.

[0034] Preferably, the second adjusting plate 21 is assembled perpendicularly to the first adjusting plate 11. In this case, it is easier to move the second adjusting plate 21 to adjust the position of the Y-axis adjusting mechanism 2, and the accuracy of adjustment in the vertical direction is improved.

[0035] Further reference Figure 1 In another embodiment of this application, the embodiment further includes a fixed base 4 connected to the second adjusting plate 21. The fixed base 4 includes a base body 41, an adjusting rod 42, and an adjusting nut 43. One end of the adjusting rod 42 is fixed to the base body 41, and the other end of the adjusting rod 42 passes through the second adjusting groove 23 and is connected to the adjusting nut 43. The fixed base 4 securely fixes the X-axis adjusting mechanism 1 and the Y-axis adjusting mechanism 2 to the needle penetration testing machine 8, and securely supports the overall structure of the test positioning fixture for position adjustment. The adjusting nut 43 can flexibly adjust the distance between the X-axis adjusting mechanism 1 and the needle penetration testing machine 8 according to the size and thickness of the battery to be tested. This structural design allows the fixture of this application to be securely fixed to the needle penetration testing machine 8 while also achieving precise and convenient position adjustment.

[0036] Preferably, the base 41 is a magnetic base or has a built-in magnet, which makes it easier to fix the fixing base 4 to the needle penetration tester 8 more securely.

[0037] Preferably, there are two fixing seats 4, which can enhance the stability of the tooling fixture. The number of fixing seats 4 can also be three or four, and can be increased or decreased according to the needs of the test. One end of each fixing seat 4 is connected to the second adjusting plate 21, and the other end is fixedly connected to the needle penetration testing machine 8. It is easy to understand that the second adjusting plate 21 is adjusted up and down along the direction of the fixing seat 4 to accommodate batteries of different thicknesses and sizes for positioning tests.

[0038] Importantly, this invention uses a fixed base 4 to support the fixture as a whole on the needle penetration testing machine 8, eliminating the need for cumbersome manual adjustments and equipment reset operations, greatly simplifying the operator's workflow and improving the efficiency of battery testing.

[0039] Further reference Figure 2 In another embodiment of this application, the needle penetration testing machine 8 includes a working platform 5, a lifting and moving mechanism 6 mounted on the working platform 5, and a test needle 7 slidably disposed on the top of the lifting and moving mechanism 6. The battery to be tested is positioned on the working platform 5 by a positioning mechanism 3, and the test needle 7 corresponds to the battery. The lifting and moving mechanism 6 can realize the movement of the test needle 7 in the X direction and the lifting and lowering in the Z direction, thus meeting the testing requirements. When conducting battery testing, the battery is adjusted to the target position in both the X and Y directions by the X-direction adjustment mechanism 1 and the Y-direction adjustment mechanism 2, respectively. Then, the lifting and moving mechanism 6 is controlled to lower the test needle 7 to the surface of the battery to be tested. Subsequently, the lifting and moving mechanism 6 controls the test needle 7 to return to its original height to test the next point or a new battery to be tested. The height of the test needle 7 in the adjusted needle penetration testing machine 8 is fixed and does not need to be repeatedly adjusted, which greatly reduces the possibility of battery damage or safety accidents caused by adjustment errors.

[0040] This embodiment was used to perform a nail penetration test on the battery:

[0041] This embodiment is fixedly installed on the needle penetration testing machine 8, so that the X-axis adjustment mechanism 1 is located on the working platform 5. According to the test requirements, the positions of the X-axis adjustment mechanism 1 and the Y-axis adjustment mechanism 2 are adjusted to the corresponding positions, so that the positioning mechanism 3 with the X-axis adjustment mechanism 1 is installed reaches the test position. At this time, the battery to be tested is positioned by the positioning edge 311 of the positioning mechanism 3. After the battery to be tested is positioned, the lifting and moving mechanism 6 is started to control the test needle 7 to move above the battery to be tested. At this time, the lifting and moving mechanism 7 moves up and down in the Z direction to realize the needle penetration test of the battery.

[0042] It should be noted that the tooling fixture of this application has precise positioning of the battery to be tested, can realize batch testing in large quantities, and has strong applicability. It can be used for nail penetration testing of various batteries, such as lithium batteries, sodium batteries, solid-state batteries, etc.
