[0029] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. 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.

[0030] The present invention will now be described in further detail with reference to the accompanying drawings:

[0031] A tool for detecting automotive decorative sewing thread 1, such as Figures 1-6 As shown, it includes a detection plate 2, on which an observation element 21 is provided. The observation element 21 includes an observation hole or a transparent plate provided on the observation side 11 of the detection plate 2; and an detection element 4 for automotive decorative sewing thread is provided on one side of the observation element 21.

[0032] The distribution of automotive decorative sewing threads is observed through the observation piece 21 on the observation side. The detection piece 4 is used to check and inspect the sewing threads. The relative position of the sewing threads and the detection piece seen through the observation window on the observation side is used to determine whether the automotive decorative sewing threads are qualified, which facilitates the inspection of sewing threads. The structure is simple, the operation is convenient, and the inspection efficiency is improved.

[0033] Example 1

[0034] Figure 1 and Figure 2 A U-shaped sewing thread detection tool is shown, wherein the detection element 4 includes a detection angle 41 disposed on one side of the observation hole for indicating the area of ​​the sewing thread.

[0035] More specifically, a reference element 3 is provided on one side of the observation hole. The reference element 3 includes at least one first reference angle 31 and a second reference angle 32 opposite to the first reference angle 31 on the opposite side. The line connecting the second reference angle 32 and the first reference angle 31 is a reference line used to indicate the standard sewing thread. Tolerance lines 43 are respectively provided on both sides of the first reference angle 31 to indicate the allowable error range of the reference line.

[0036] like Figure 3 The second reference angle 32 is provided with detection angles 41 on both sides, which are used to detect the two sewing threads of the U-shaped sewing thread. A pair of first detection lines 42 are provided on both sides of the detection angle 41, which are used to indicate the qualified area range of the sewing thread 6.

[0037] The first reference angle 31 is an acute angle, and the second reference angle 32 is an obtuse angle; one side of the detection plate 2 is a positioning side 12, and the positioning side 12 is provided with the following positioning member 5 or a combination thereof: a Z-direction positioning member 51, an X-direction positioning member 52, and a Y-direction positioning member 53. The positioning member 5 is used to cooperate and position with the groove, plane, or curved surface near the sewing line of the automobile decoration, and the specific form of the positioning member 5 can be designed and selected according to the actual distribution of the sewing line.

[0038] In one specific implementation, the spacing of the U-shaped sewing line is 5 mm, the distance between the two first reference angles is 5 mm, one detection angle 41 is arranged on each side of the second reference angle, and the tolerance is set to 1.5 mm, so that the spacing between the two detection angles 41 is 3 mm. When the sewing line falls within the range of the two detection angles 41, it is determined to be qualified. When two sewing lines fall within the range of a corresponding pair of detection angles 41 on the left and right sides at the same time, the U-shaped sewing line is determined to be qualified.

[0039] Optionally, considering the reference side decoration line tolerance, the line spacing standard is set to 2.5±0.5. Two tolerance lines 43 are drawn on the side of the first reference angle, and the standard decoration line is used as a reference, with +0.5 on one side and -0.5 on the other side, which can also monitor whether the line spacing is qualified. Four first detection lines 42 are drawn on one side of the detection angle, and the lines are drawn within ±0.5 of the sharp angle, which expands the error range through the first detection line 42 and the tolerance line 43. If the positioning decoration line deviates by +0.5, the left line is observed; if it deviates by -0.5, the right line is observed. When the reference line exceeds the tolerance line range, it is determined to be unqualified. When the sewing line exceeds the first detection line range, it is also determined to be unqualified.
