Description

Technical Field

[0001] This utility model relates to the field of detection auxiliary technology, and in particular to a copper busbar inspection tool. Background Technology

[0002] In the manufacturing process of electrical products, copper busbars, as critical electrical connection components, often require secondary processing such as bending and punching according to the internal structure of the equipment. Due to installation space constraints, the requirements for the hole positions, shape, and dimensional accuracy of copper busbars are extremely stringent. Therefore, efficient and accurate inspection of their processing quality is essential during production. Currently, for the inspection of high-precision copper busbars, contour-following fixtures are commonly used. This involves creating contour grooves on the fixture base that match the shape of the copper busbar. During inspection, operators place the copper busbar into the contour groove, and the ability to smoothly insert it qualitatively determines whether the product's shape and hole spacing are up to standard.

[0003] However, in terms of testing operations, since the copper busbar and the conformal groove need to be precisely matched, the copper busbar is very prone to jamming after being placed in due to excessive tightness or the presence of tiny burrs, making it difficult to remove and seriously affecting the continuity of testing and work efficiency. Utility Model Content

[0009] Preferably, the detection mold further includes: A main body base, wherein the main body is mounted on the main body base, and the main body base covers at least the area where the receiving groove and the contour detection groove provided on the main body are located.

[0010] Preferably, it further includes: A base, on which the ejection mechanism is mounted; A support column connects the testing mold and the base.

[0011] Preferably, the driving unit includes: The drive seat is located below the top portion; The handle is pivotally connected to the drive seat via a hinge shaft, and the actuating end of the handle is located at the bottom of the ejector portion; A reset torsion spring is fitted onto the hinge shaft, and the first torsion arm of the reset torsion spring is fixedly connected to the hinge shaft; the second torsion arm of the reset torsion spring is connected to the drive seat. The handle can be switched between a first position and a second position; in the first position, the ejector part is in the retracted position; in the second position, the handle pushes the ejector part, and the ejector part is in the ejected position. Under the action of external force, the handle moves from the first position to the second position; when the external force is removed, the reset torsion spring drives the handle to return from the second position to the first position.

[0012] Preferably, the ejector portion includes: An ejector seat is disposed on the actuator end of the drive seat and the handle; A push rod is fitted into the push-out seat, and its end corresponds to the position of the contour detection groove; The ejector part is in the ejector position, and the ejector rod passes through the detection mold and extends into the contour detection groove, which can eject the copper busbar to be inspected placed in the contour detection groove; The ejector section is in the retracted position, and the ejector rod is separated from the testing mold.

[0013] Preferably, the ejector seat includes: The upper ejector seat is fitted with the ejector rod. The lower ejector seat is mounted on the upper ejector seat, and the lower ejector seat covers at least the area where the ejector rod is located.

At the same time, the smooth ejection process maintains the stability of the fixture benchmark, ensuring the repeatability and consistency of inspection data, and providing a reliable guarantee for quality control in mass production.

[0016] This invention integrates easily damaged components such as positioning and detection parts into replaceable inserts. This allows the fixture to regain its accuracy even if the positioning or detection parts wear down due to frequent operation or the contour detection groove becomes out of tolerance due to repeated testing. This significantly reduces the long-term maintenance cost and cycle of the fixture.

[0017] This invention provides precise guidance for the movement of the ejector part through the pre-set ejection channel on the insert, ensuring smooth and accurate ejection action and effectively avoiding possible scratches and damage to the copper busbar or contour detection groove during the ejection process.

[0018] This invention connects the insert to the receiving groove on the main body to form a contour detection groove. The contour accuracy of the groove is ensured by both the insert and the main body, avoiding the difficulties of directly machining complex contour grooves on a large main body. This significantly improves the overall accuracy and consistency of the final formed contour detection groove. Furthermore, it allows for adapting the same fixture body to new inspection tasks by simply replacing the corresponding insert module for different specifications of copper busbars, greatly enhancing the fixture's versatility and economy.

[0022] To make the technical problems solved by this utility model, the technical solutions adopted, and the technical effects achieved clearer, the technical solutions of the embodiments of this utility model are further described in detail below. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0023] 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.

[0024] 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.

The X-axis direction shown in the figure is the first direction, the Y-axis direction is the second direction, and the Z-axis direction is the third direction.

[0026] like Figures 1 to 7As shown, this embodiment provides a copper busbar inspection fixture, including: an inspection mold 100 and an ejection mechanism 400. The inspection mold 100 has a contoured inspection groove for accommodating a copper busbar 200 to be inspected; the ejection mechanism 400 is located below the inspection mold 100; the ejection mechanism 400 includes a driving part and an ejection part; the driving part drives the ejection part to move upward and extend into the contoured inspection groove, thereby ejecting the copper busbar 200 to be inspected placed in the contoured inspection groove. Here, the shape and size of the contoured inspection groove correspond to the shape and size of the copper busbar 200 to be inspected, so as to facilitate the placement of the copper busbar 200 to be inspected in the contoured inspection groove for inspection.

[0027] This embodiment utilizes an ejection mechanism located below the inspection mold. The ejection part, controlled by a drive unit, extends upwards into the contour inspection groove, smoothly and steadily ejecting the tightly fitted copper busbar to be inspected. This effectively solves the long-standing problem of removing parts from high-precision inspection fixtures. It not only achieves rapid and non-destructive removal, significantly improving inspection efficiency, but also avoids damage to the copper busbar surface and contour inspection groove caused by manual prying or tool manipulation, ensuring product quality and fixture lifespan. Simultaneously, the stable ejection process maintains the stability of the fixture's reference, ensuring the repeatability and consistency of inspection data, providing a reliable guarantee for quality control in mass production.

[0028] In one embodiment, the detection mold 100 includes a main body 110 and an insert 120. The main body 110 is provided with a receiving groove 111; the insert 120 is detachably installed in the receiving groove 111, the contour detection groove includes a first detection groove 310, and the insert 120 and the receiving groove 111 are mutually connected to form the first detection groove 310; the insert 120 is provided with an ejection channel 121 at a corresponding position; the insert 120 is provided with a positioning element 130 and a detection element 140.

[0029] During the inspection process, the operator first attempts to fit the main reference hole on the copper busbar 200 to be inspected onto the positioning piece 130. If the main reference hole on the copper busbar 200 fails to fit with the positioning piece 130, it indicates that the main reference hole or shape of the copper busbar 200 is seriously out of tolerance, and the copper busbar 200 can be determined to be a defective product. If the main reference hole on the copper busbar 200 successfully fits with the positioning piece 130, the current state is maintained, and further attempts are made to fit all the inspection holes on the copper busbar 200 onto their corresponding inspection pieces 140. Only when all the inspection holes on the copper busbar 200 can be successfully fitted into their corresponding inspection pieces 140 can the hole spacing of the copper busbar 200 be determined to be qualified. If any inspection hole on the copper busbar 200 cannot be successfully fitted into its corresponding inspection piece 140, the copper busbar 200 can be determined to be a defective product. It should be noted that the number of positioning elements 130 and detection elements 140 shown in the figure is not a limitation and can be set according to the detection requirements of the copper busbar 200 to be inspected.

[0030] like Figure 5 and Figure 6 As shown, in this embodiment, the pre-set ejection channel 121 on the insert 120 provides precise guidance for the movement of the ejection part, ensuring the smoothness and accuracy of the ejection action and effectively avoiding possible scratches and damage to the copper busbar or contour detection groove during the ejection process.

[0031] In this embodiment, the insert 120 and the receiving groove 111 can be processed by slow wire cutting process to make the first detection groove 310 meet the tolerance size requirements of high precision. At the same time, it can effectively avoid the process difficulties and deformation risks that are difficult to avoid when directly processing complex contour detection grooves on the main body 110.

[0032] This embodiment can change the shape of the first detection groove 310 by replacing the inserts 120 with different contours, so as to quickly adapt to the detection requirements of copper busbars of different specifications on the same main body 110, which is conducive to rapid production changeover and improves the versatility of the inspection tool.

[0033] In this embodiment, the insert 120 and the receiving groove 111 of the main body 110 can be fixedly connected by screws 700.

[0034] Furthermore, the positioning element 130 and the detection element 140 are respectively embedded in the insert 120, and their ends both protrude from the surface of the insert 120. Here, vulnerable components such as the positioning element and the detection element are integrated into the replaceable insert 120, so that even if the positioning element or the detection element wears out due to frequent operation during long-term use, only the individual insert or the faulty part needs to be replaced to restore the accuracy of the fixture, thereby significantly reducing the long-term maintenance cost and cycle of the fixture.

[0035] Furthermore, a first clearance opening 116 is provided at the edge of the receiving groove 111. By forming an opening at the edge of the key contour of the detection groove, an operating channel is provided for the insertion of the insert 120, which makes it easier to install and position the insert 120, effectively avoids assembly difficulties caused by spatial interference, and ensures the assembly accuracy and efficiency of the first detection groove 310.

[0036] In one embodiment, reference Figure 7 As shown, the contour detection groove further includes a second detection groove 320, which is disposed on the main body 110. The second detection groove 320 has a bent section; a second clearance opening 117 is provided through the edge of the second detection groove 320, and the second clearance opening 117 is located at the bent section of the second detection groove 320. It should be noted that... Figures 1 to 6 The second clearance opening 117 is not shown in the embodiment shown.

[0037] In this embodiment, the copper busbar 200 to be inspected is generally a bent sheet structure. By bending around obstacles, it adapts to the limited wiring space, achieving safe, reliable, and efficient power transmission. Here, the second detection slot 320 can match the outer contour of the copper busbar 200 to be inspected.

[0038] The bends in the copper busbar 200 under inspection often produce tiny metal protrusions or burrs due to processing. By providing a second clearance opening 117 along the edge of the bend section of the second inspection groove 320, a dedicated chip-carrying space and clearance space are provided for these protrusions on the copper busbar 200 under inspection. This effectively prevents the protrusions from getting stuck in the second inspection groove 320 and interfering with the final positioning of the copper busbar 200 under inspection, thereby ensuring the authenticity and accuracy of the bending angle detection results, and also preventing damage to the inspection fixture and product surface from forced insertion or removal.

[0039] In one embodiment, the detection mold 100 further includes a main body base 150, on which the main body 110 is mounted, and the main body base 150 at least covers the area where the receiving groove 111 and the contour detection groove disposed on the main body 110 are located.

[0040] By setting the main body seat 150, the thickness of the main body 100 can be reduced as much as possible, which enhances the overall rigidity and bending strength of the entire inspection mold, effectively resists the impact of the ejection force, and ensures that the geometric accuracy of the contour inspection groove remains stable during long-term use.

[0041] In this embodiment, the main body base 150 and the main body 110 can be fixedly connected by screws 700.

[0042] In one embodiment, it further includes a base 500 and a support column 600. The ejection mechanism 400 is mounted on the base 500; the support column 600 is connected between the detection mold 100 and the base 500.

[0043] Here, by setting up the base 500 and the support column 600, the inspection mold and the ejection mechanism are arranged in a two-layer structure, providing suitable working space for the inspection mold and the ejection mechanism, and facilitating the overall movement of the copper busbar inspection fixture. It should be noted that the height of the support column 600 needs to match the movement distance of the ejection mechanism in the third direction (Z-axis direction as shown in the figure).

[0044] In one embodiment, the drive unit includes a drive seat 410, a handle 420, and a return torsion spring. The drive seat 410 is located below the ejector portion; the handle 420 is pivotally connected to the drive seat 410 via a hinge shaft, and the actuating end of the handle 420 is located at the bottom of the ejector portion; the return torsion spring is fitted onto the hinge shaft, and the first torsion arm of the return torsion spring is fixedly connected to the hinge shaft; the second torsion arm of the return torsion spring is connected to the drive seat 410.

[0045] The handle 420 can be switched between a first position and a second position. In the first position, the ejector part is in the retracted position. In the second position, the handle 420 pushes against the ejector part, and the ejector part is in the ejected position. Under the action of external force, the handle 420 moves from the first position to the second position; when the external force is removed, the return torsion spring drives the handle 420 to return from the second position to the first position.

[0046] Furthermore, the drive base 410 is provided with a limiting structure. When the handle 420 is in the first position, the handle 420 abuts against the limiting structure on the drive base 410, thereby providing a mechanical endpoint for the first position of the handle 410, and providing a supporting force to the bottom of the ejector part through the actuating end of the handle 420, so that the ejector part can be stably maintained in the retracted position.

[0047] The handle 420 here can be an L-shaped structure, with the long arm end for pressing to provide greater torque. The short arm end serves as the actuator, thus efficiently and effortlessly pushing out the ejector.

[0048] In one embodiment, the ejector portion includes an ejector seat 430 and an ejector rod 440. The ejector seat 430 is disposed on the actuating end of the drive seat 410 and the handle 420; the ejector rod 440 is embedded in the ejector seat 430, and its end corresponds to the position of the contour detection groove.

[0049] When the ejector is in the ejector position, the ejector rod 440 passes through the detection mold 100 and extends into the contour detection groove, which can eject the copper busbar 200 to be inspected placed in the contour detection groove; when the ejector is in the retracted position, the ejector rod 440 is separated from the detection mold 100.

[0050] It should be noted that each component through which the push rod 440 moves needs to have a corresponding ejection channel 121 reserved. In other words, the ejection channel 121 is not only set on the insert, but can be arranged according to the movement path of the push rod 440. No specific limitation is made here.

[0051] Furthermore, a return spring is fitted onto the push rod 440. One end of the return spring rests against the ejector seat 430, and the other end rests against the fixed main body seat 150. When the push rod 440 moves upward to eject, it compresses the return spring, storing energy. When the push rod 440 moves downward to retract, the restoring force of the return spring pushes the ejector seat 430 downward, thereby causing the push rod 440 to retract.

[0052] Furthermore, the ejector seat 430 includes an upper ejector seat 431 and a lower ejector seat 432. The ejector rod 440 is fitted onto the upper ejector seat 431; the upper ejector seat 431 is mounted on the lower ejector seat 432, and the lower ejector seat 432 at least covers the area where the ejector rod 440 is located.

[0053] The upper ejector seat 431 described here can be made of aluminum to assist in limiting the position of the ejector rod 440. The lower ejector seat 432 can be made of steel to avoid damaging the upper ejector seat 431.

[0054] In one embodiment, reference Figure 4 As shown, the testing mold 100 is provided with a first reference hole 113, a second reference hole 114 and a third reference hole 115 that are parallel to each other along the central axis direction; the first reference hole 113 and the second reference hole 114 are spaced apart along a first direction (the X-axis direction as shown in the figure); the second reference hole 114 and the third reference hole 115 are spaced apart along a second direction (the Y-axis direction as shown in the figure), wherein the second direction is perpendicular to the first direction.

[0055] The measurement datum is based on a rectangular coordinate system constructed by the three datum holes on the main body of the fixture. This avoids discrepancies in other inspection points and comparison data caused by differences in the selection of datum positions by the inspectors.

[0056] In the description herein, it should be understood that the terms "upper," "lower," "left," "right," and other orientations or positional relationships are used only for ease of description and simplification of operation, and do not indicate or imply that the device or component 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. Furthermore, the terms "first" and "second" are merely used for distinction in description and have no special meaning.

In this specification, illustrative expressions of the above terms do not necessarily refer to the same embodiment or example.
