[0026] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0027] The utility model relates to a tool for detecting the curvature of the side of a copper strip, comprising: a base 1 for placing and abutting against a copper strip body 3 and a groove 2 provided on the surface of the base 1. Figure 1 shown.

[0028] Figure 2-Figure 4 The first embodiment of the present invention is shown: In this embodiment, the base 1 is "L"-shaped, comprising: a placement portion 11 for placing the workpiece to be inspected and an abutment portion 12 perpendicularly connected to an edge of the placement portion 11 and for abutting an edge of the placed workpiece to be inspected. The groove 2 comprises: a first side wall 21 and a second side wall 22 arranged opposite to each other, and a third side wall 23 for connecting the first side wall 21 and the second side wall 22. In order to facilitate detection, the groove 2 is opened on the surface of the placement portion 11 and is located at the junction between the placement portion 11 and the abutment portion 12, while extending to the outside at both ends along the junction. Therefore, when the edge of the copper strip body abuts the abutment portion 12, its abutment edge just hangs above the groove 2. Since the edge curvature of the copper strip body 3 needs to be guaranteed to be within 1mm, the spacing between the first side wall 21 and the second side wall 22 of the groove 2 is 1mm, that is, the width of the groove 2 is 1mm.

[0029] When using, Figure 3 As shown, the copper strip body 3 is placed on the surface of the placement portion 11, and one edge of the copper strip body 3 is abutted against the abutment portion 12. By observing the degree of exposure of the groove 2, the side bend detection is realized, that is: if the groove 2 is completely exposed at any position of the abutment edge of the copper strip body 3, it is an unqualified product; on the contrary, if the groove 2 is not exposed, it is a qualified product.

[0030] Figure 5-Figure 6The second embodiment of the present invention is shown, which is different from the first embodiment in that: since the first embodiment requires manual support of the copper strip main body 3, in order to reduce the instability of manual holding and improve the detection accuracy, a slide groove 4 perpendicular to the groove 2 can be opened on the surface of the placement part 11, and an elastic element 5 and a slider 7 adapted to the slide groove 4 are also provided in the slide groove 4, and the slider 7 abuts against the end of the elastic element 5 close to the groove 2, and the top of the slider 7 also passes through the slide groove 4 and is connected to the movable part 6 parallel to the groove 2. In this embodiment, the movable part 6 is square, and the bottom surface of the movable part 6 fits the placement part 11 and is slidably connected to the surface of the placement part 11 through the slider 7 and the elastic element 5, which is used to cooperate with the abutting part 12 to clamp the copper strip main body 3 placed on the surface of the placement part 11. In this embodiment, two groups of slide grooves 4 are opened in parallel, and their cross-section is "T"-shaped. The number and shape can also be adaptively adjusted according to the actual length of the base 1, which is not limited in this application.

[0031] It should be noted that, in this embodiment, the elastic element 5 is preferably a spring. When the elastic element 5 is in a natural state, the movable portion 6 is infinitely close to or in contact with the abutting portion 12 .

[0032] During specific use, the movable part 6 is moved away from the abutment part 12 to compress the elastic element 5, and the copper strip body 3 is placed in the clamping space formed by the movable part 6 and the abutment part 12, and is fitted into the placement part 11. The elasticity of the elastic element 5 allows the movable part 6 and the abutment part 12 to clamp the copper strip body 3, and then the degree of exposure of the groove 2 is observed to realize the side bending detection of the copper strip body 3. The principle is the same as that of the first embodiment, and will not be elaborated here.

[0033] Finally, it should be noted that the above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art will be able to modify the technical solutions described in the aforementioned embodiments or replace some of the technical features therein with equivalents. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention shall be included within the scope of protection of the present invention.
