Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of flatness detection devices, and in particular to a flatness detection fixture. Background Technology
[0002] Copper and aluminum conductor bars are used in the battery packs of new energy vehicles to connect battery modules. In the actual production of conductor bars, a common problem is asymmetry in the flatness of the two ends, meaning the two ends of the conductor bar are not on the same plane. Therefore, a flatness testing device is needed to check the flatness of the conductor bars during production. If the test fails, the conductor bar needs to be reshaped.
[0003] Existing flatness testing methods typically involve a combination of a dial indicator and a support. While this method offers high measurement accuracy, it requires fixing, measuring, and reading the dial indicator, resulting in low testing efficiency.
[0004] Therefore, there is an urgent need to propose a flatness inspection fixture to solve the above problems. Utility Model Content

[0009] A first detection component and a second detection component are arranged at intervals along the length of the working base plate. The positions of the first detection component and the second detection component are adapted to the shape of the conductive strip, so that the first end and the second end of the conductive strip can be pre-laid flat on the detection end face of the first detection component and the detection end face of the second detection component, respectively, for testing.
[0010] During testing, one of the first detection component and the second detection component can fix the conductive strip to its corresponding detection end face, and observe whether the conductive strip is attached to the detection end face corresponding to the other of the first detection component and the second detection component.
[0011] As an optional technical solution for flatness inspection fixture, the first inspection component includes a first clamp, and the second inspection component includes a second clamp. The first clamp is fixed to the working base plate and can press the first end of the conductive strip onto the inspection end face of the first inspection component. The second clamp is fixed to the working base plate and can press the second end of the conductive strip onto the inspection end face of the second inspection component.
[0012] As an optional technical solution for flatness inspection fixture, the first inspection component further includes a first positioning seat, and the second inspection component further includes a second positioning seat. One end of the first positioning seat and one end of the second positioning seat are both fixed to the working base plate, and the other end of the first positioning seat and the other end of the second positioning seat are respectively provided with the corresponding inspection end face.
[0013] As an optional technical solution for flatness inspection fixture, both the detection end face of the first positioning seat and the detection end face of the second positioning seat are provided with positioning pins, and both the first end and the second end of the conductive strip are provided with positioning holes. By aligning the two positioning holes with the corresponding positioning pins, the first end and the second end can be pre-placed on the first positioning seat and the second positioning seat respectively.
[0014] As an optional technical solution for flatness inspection tooling, the first clamp includes a first pressure head and a first movable part, and the second clamp includes a second pressure head and a second movable part. One end of the first movable part and one end of the second movable part are rotatably connected to the working base plate, and the other end of the first movable part and the other end of the second movable part are respectively connected to the first pressure head and the second pressure head.
[0015] As an optional technical solution for flatness inspection fixture, the first movable component includes a first base and a first rotating rod, and the second movable component includes a second base and a second rotating rod. The first base and the second base are respectively fixed to the working base plate. One end of the first rotating rod and one end of the second rotating rod are respectively rotatably connected to the first base and the second base, and the other end of the first rotating rod and the other end of the second rotating rod are respectively connected to the first pressure head and the second pressure head.
[0016] As an optional technical solution for flatness inspection tooling, the first inspection component further includes a first fixed base, the two ends of which are respectively connected to the working base plate and the first clamp; the second inspection component further includes a second fixed base, the two ends of which are respectively connected to the working base plate and the second clamp.
[0017] As an optional technical solution for flatness testing fixture, the flatness testing fixture further includes a support base assembly, which is fixed to the working base plate and can support the middle position of the conductive strip.
[0018] As an optional technical solution for flatness inspection tooling, the support assembly includes a column and a connecting beam. One end of the connecting beam is connected to the working base plate, and the other end of the connecting beam extends to the outer edge of the working base plate to support and connect to the column.
[0019] As an optional technical solution for flatness inspection fixtures, the connecting beam is connected to the working base plate by bolts.
[0020] The beneficial effects of this utility model are:
[0021] This utility model provides a flatness testing fixture for detecting whether the first and second ends of a conductive strip are on the same plane. It includes a working base plate, a first testing component, and a second testing component. The first and second testing components are spaced apart along the length of the working base plate, which supports and fixes them. The positions of the first and second testing components are adapted to the shape of the conductive strip, allowing the first and second ends of the conductive strip to be pre-laid flat on the testing end faces of the first and second testing components, respectively, awaiting testing. During testing, one of the first and second testing components can fix the conductive strip against its corresponding testing end face, and the fixture is used to observe whether the conductive strip adheres to the testing end face of the other component. For example, if the detection end face of the first detection component is fixedly attached to the first end of the conductive strip, and the second end of the conductive strip at the detection end face of the second detection component is attached to the detection end face of the second detection component without any lifting, then the first and second ends of the conductive strip are on the same plane (the first and second ends are symmetrical), meaning the conductive strip is a qualified product. If the second end of the conductive strip at the detection end face of the second detection component is not attached to the detection end face of the second detection component and is lifting, then the first and second ends of the conductive strip are not on the same plane (the first and second ends are asymmetrical), meaning the conductive strip needs product reshaping. It is evident that this flatness detection fixture does not require dial indicators or other measuring tools, has a simple structure, and does not require reading calculations; the result can be obtained simply by fixing one end of the conductive strip and observing the other end. The detection operation is simple and the detection efficiency is high. Attached Figure Description

[0028] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present invention and not intended to limit it. Furthermore, it should be noted that, for ease of description, the accompanying drawings show only the parts relevant to the present invention, not the entire structure.
[0029] In the description of this utility model, unless otherwise explicitly specified and limited, the terms "connected," "linked," and "fixed" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.
[0030] 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.
[0031] In the description of this embodiment, the terms "upper," "lower," "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.
[0032] The flatness detection fixture provided in this embodiment is used to detect whether the first end and the second end of the two ends of the conductive strip are on the same plane. It has a simple structure, simple detection operation and high detection efficiency.
[0033] Specifically, such as Figures 1 to 3 As shown, the flatness testing fixture includes a working base plate 100, a first testing component 200, and a second testing component 300. The first testing component 200 and the second testing component 300 are spaced apart along the length of the working base plate 100. The positions of the first testing component 200 and the second testing component 300 are adapted to the shape of the conductive strip 10, allowing the first end 11 and the second end 12 of the conductive strip 10 to be pre-laid flat on the testing end faces of the first testing component 200 and the second testing component 300, respectively, awaiting testing. During testing, one of the first testing component 200 and the second testing component 300 can cause the conductive strip 10 to adhere to its corresponding testing end face, and it is observed whether the conductive strip 10 adheres to the testing end face corresponding to the other of the first testing component 200 and the second testing component 300.
[0034] Based on the above design, the first detection component 200 and the second detection component 300 are spaced apart along the length of the working base plate 100, which supports and fixes the first detection component 200 and the second detection component 300. The positions of the first detection component 200 and the second detection component 300 are adapted to the shape of the conductive strip 10, so that the first end 11 and the second end 12 of the conductive strip 10 can be pre-laid flat on the detection end faces of the first detection component 200 and the second detection component 300, respectively, awaiting detection. During actual detection, one of the first detection component 200 and the second detection component 300 can make the conductive strip 10 adhere and fix itself to its corresponding detection end face, and it is observed whether the conductive strip 10 adheres to the detection end face corresponding to the other of the first detection component 200 and the second detection component 300. For example, if the detection end face of the first detection component 200 is fixedly attached to the first end 11 of the conductive strip 10, and the second end 12 of the conductive strip 10 at the detection end face of the second detection component 300 is attached to the detection end face of the second detection component 300 without any lifting, then the first end 11 and the second end 12 of the conductive strip 10 are on the same plane (the first end 11 and the second end 12 are symmetrical), that is, the conductive strip 10 is a qualified product; if the second end 12 of the conductive strip 10 at the detection end face of the second detection component 300 is not attached to the detection end face of the second detection component 300 and is lifted, then the first end 11 and the second end 12 of the conductive strip 10 are not on the same plane (the first end 11 and the second end 12 are asymmetrical), that is, the conductive strip 10 needs to be product shaped. The detection end face of the second detection component 300 is fixedly attached to the second end 12 of the conductive strip 10. If the first end 11 of the conductive strip 10 at the detection end face of the first detection component 200 is attached to the detection end face of the first detection component 200 without any lifting, then the first end 11 and the second end 12 of the conductive strip 10 are on the same plane (the first end 11 and the second end 12 are symmetrical), meaning the conductive strip 10 is a qualified product. If the first end 11 of the conductive strip 10 at the detection end face of the first detection component 200 is not attached to the detection end face of the first detection component 200 and is lifting, then the first end 11 and the second end 12 of the conductive strip 10 are not on the same plane (the first end 11 and the second end 12 are asymmetrical), meaning the conductive strip 10 needs to be reshaped. It can be seen that this flatness detection fixture does not require measuring tools such as dial indicators, has a simple structure, and does not require reading calculations. The result can be obtained simply by fixing one end of the conductive strip 10 and observing the other end, making the detection operation simple and efficient.
[0035] It should be noted that, in order to improve the pass rate, if the test result shows that the conductive strip 10 is a qualified product, the pressing and observation operation of the first end 11 and the second end 12 should be changed, and the product should be retested to see if it is a qualified product.
[0036] In this embodiment, the conductive strip 10 is made of copper or aluminum.
[0037] Typically, the conductive strip 10 is quite long and is usually L-shaped. Therefore, if only the first end face and the second end 12 at both ends of the conductive strip 10 are fixed, the conductive strip 10 is prone to tipping over due to its own weight. Therefore, the flatness detection fixture also includes a support assembly 400, which is fixed to the working base plate 100 and can support the middle position of the conductive strip 10.
[0038] Furthermore, the support assembly 400 includes a column 410 and a connecting beam 420. One end of the connecting beam 420 is connected to the working base plate 100, and the other end of the connecting beam 420 extends to the outer edge of the working base plate 100 to support the connecting column 410, thereby reducing the area of the working base plate 100, saving materials, and making the structure compact.
[0039] In this embodiment, the connecting beam 420 is bolted to the working base plate 100.
[0040] Continue as Figure 2 and Figure 3 As shown, the first detection component 200 includes a first clamp 210, and the second detection component 300 includes a second clamp 310. The first clamp 210 is fixed to the working base plate 100 and can press the first end 11 of the conductive strip 10 onto the detection end face of the first detection component 200. The second clamp 310 is fixed to the working base plate 100 and can press the second end 12 of the conductive strip 10 onto the detection end face of the second detection component 300. The first clamp 210 and the second clamp 310 have simple structures and are easy to operate, and can vertically press and fix the conductive strip 10.
[0041] Furthermore, the first detection component 200 also includes a first positioning seat 220, and the second detection component 300 also includes a second positioning seat 320. One end of the first positioning seat 220 and one end of the second positioning seat 320 are both fixed to the working base plate 100. The other end of the first positioning seat 220 and the other end of the second positioning seat 320 are respectively provided with corresponding detection end faces. The first positioning seat 220 and the second positioning seat 320 can position the first end 11 and the second end 12 of the conductive strip 10.
[0042] Furthermore, both the detection end face of the first positioning seat 220 and the detection end face of the second positioning seat 320 are provided with positioning pins, and both the first end 11 and the second end 12 of the conductive strip 10 are provided with positioning holes. By aligning the two positioning holes with the corresponding positioning pins, the first end 11 and the second end 12 can be pre-positioned in the first positioning seat 220 and the second positioning seat 320, respectively. On the one hand, the first end 11 and the second end 12 of the conductive strip 10 can be pre-positioned, and on the other hand, the first end 11 and the second end 12 of the conductive strip 10 can be fixed to prevent deviation during detection.
[0043] In this embodiment, the first clamp 210 includes a first clamping head 211 and a first movable member 212, and the second clamp 310 includes a second clamping head 311 and a second movable member 312. One end of the first movable member 212 and one end of the second movable member 312 are rotatably connected to the working base plate 100, and the other end of the first movable member 212 and the other end of the second movable member 312 are respectively connected to the first clamping head 211 and the second clamping head 311.
[0044] Furthermore, the first movable component 212 includes a first base and a first rotating rod, and the second movable component 312 includes a second base and a second rotating rod. The first base and the second base are respectively fixed to the working base plate 100. One end of the first rotating rod and one end of the second rotating rod are respectively rotatably connected to the first base and the second base. The other end of the first rotating rod and the other end of the second rotating rod are respectively connected to the first pressure head 211 and the second pressure head 311.
[0045] Furthermore, the first movable member 212 and the second movable member 312 also include a first driving member and a second driving member, respectively. One end of the first driving member is rotatably connected to the first base, and the other end is fixed to the first rotating rod. Rotating the first driving member causes the first rotating rod to open the first clamp 210 (the first clamp head 211 is away from the detection end face of the first positioning seat 220) or close the first clamp 210 (the first clamp head 211 is close to the detection end face of the first positioning seat 220). One end of the second driving member is rotatably connected to the second base, and the other end is fixed to the second rotating rod. Rotating the second driving member causes the second rotating rod to open the second clamp 310 (the second clamp head 311 is away from the detection end face of the second positioning seat 320) or close the second clamp 310 (the second clamp head 311 is close to the detection end face of the second positioning seat 320).
[0046] In this embodiment, the first detection component 200 further includes a first fixing base 230, with its two ends connected to the working base plate 100 and the first clamp 210, respectively; the second detection component 300 further includes a second fixing base 330, with its two ends connected to the working base plate 100 and the second clamp 310, respectively. The first fixing base 230 and the second fixing base 330 respectively provide fixed support for the first clamp 210 and the second clamp 310.
[0047] The specific testing steps for conductive strip 10 are as follows:
[0048] S1: Rotate the first driving component and the second driving component respectively to open the first clamp 210 and the second clamp 310;
[0049] S2: Align the positioning holes on the first end 11 and the second end 12 of the conductive strip 10 with the positioning pins on the corresponding detection end faces, place the conductive strip 10 on the first detection component 200 and the second detection component 300, and place the middle part of the conductive strip 10 on the column.
[0050] S3: Rotate the first driving member (or the second driving member) to close the first clamp 210 (second clamp 310), so that the first pressure head 211 (second pressure head 311) presses the first end 11 (second end 12) against the detection end face of the first positioning seat 220 (second positioning seat 320);
[0051] S4: Observe whether the second end 12 (first end 11) is in contact with the detection end face of the second positioning seat 320 (first positioning seat 220);
[0052] S5: If there is no lifting when the material is bonded, swap the pressing object and the observation object (the one being pressed between the first end 11 and the second end 12 is called the pressing object, and the one being observed between the first end 11 and the second end 12 is called the observation object). Repeat the above steps S1-S4. If the observation object is still bonded without lifting, the conductive strip 10 is a qualified product. If it is not bonded and lifting occurs, the conductive strip 10 is a defective product and needs to be reshaped.
[0053] 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.
