[0030] In order to make the purpose, technical solutions and advantages of the present disclosure clearer, the present disclosure will be further described in detail below in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present disclosure, rather than all of the embodiments.

The insulation resistance detection auxiliary device used is usually two test leads 910 (conductor rods). When testing the arc surface of the component to be tested, it is very easy to scratch the surface of the component to be tested; and in the insulation resistance test, point-to-point power supply will produce an electrostatic adsorption effect to avoid leakage sparking due to insufficient surface electrical performance, causing film damage. Therefore, the insulation resistance detection device in the related art cannot measure the insulation resistance of large-diameter arc surfaces, and cannot achieve consistent pressure during testing, resulting in errors in the measurement results.

The insulation resistance detection auxiliary device 10 of the present disclosure is used for the insulation resistance detection device, which is mainly used for the surface of the cooling roller of the vacuum evaporation coating equipment to spray ceramic coating material, and to perform insulation resistance test on the surface of the product, and is particularly suitable for the materials to be tested with high requirements for the insulation performance of the large diameter cylindrical surface. During use of the insulation resistance detection auxiliary device 10 disclosed in the present invention, the first mounting assembly 120 and the second mounting assembly 130 are simultaneously contacted with the surface of the component under test 800 by pressing down the insulation resistance detection auxiliary device 10; during the pressing down process, the first roller 121 releases the detection contact sheet 110 of the second preset length, so that the detection contact sheet 110 is attached to the surface of the component under test 800. During the insulation resistance detection, a test surface is formed between the detection contact sheet 110 and the component under test 800, and the pressure on the surface of the component under test 800 is consistent, which prevents the component under test 800 from being scratched during the detection process and increases the accuracy of the detection.

[0037] The optional embodiments of the present disclosure are described in detail below with reference to the accompanying drawings.

[0038] Figure 2 A schematic diagram of a detection unit 100 according to an embodiment of the present disclosure is shown. Figure 3 FIG. 1 is a schematic diagram of an insulation resistance detection auxiliary device 10 according to another embodiment of the present disclosure. Figure 2 and Figure 3As shown, according to a specific embodiment of the present disclosure, on the one hand, an insulation resistance detection auxiliary device 10 is provided, and the insulation resistance detection auxiliary device 10 may include: a detection part 100, and the detection part 100 may include: a detection contact piece 110; a first mounting component 120, and one end of the detection contact piece 110 is mounted on the first mounting component 120; a second mounting component 130, and the other end of the detection contact piece 110 is mounted on the second mounting component 130; wherein the first mounting component 120 and / or the second mounting component 130 may include a first roller 121, and the detection contact piece 110 of a first preset length is rolled up on the first roller 121, and the first roller 121 is configured to release the detection contact piece 110 of a second preset length when the detection contact piece 110 is subjected to pressure. The insulation resistance detection auxiliary device 10 of the present disclosure is used for an insulation resistance detection device, and the insulation resistance detection auxiliary device 10 is particularly used for detecting the insulation resistance of an arc surface. During use of the insulation resistance detection auxiliary device 10 disclosed in the present invention, the first mounting assembly 120 and the second mounting assembly 130 are simultaneously contacted with the surface of the component under test 800 by pressing down the insulation resistance detection auxiliary device 10; during the pressing down process, the first roller 121 releases the detection contact sheet 110 of the second preset length, so that the detection contact sheet 110 is attached to the surface of the component under test 800. During the insulation resistance detection, a test surface is formed between the detection contact sheet 110 and the component under test 800, and the pressure on the surface of the component under test 800 is consistent, which prevents the component under test 800 from being scratched during the detection process and increases the accuracy of the detection.

[0039] It should be noted that the insulation resistance detection auxiliary device 10 disclosed in the present invention is not only suitable for insulation resistance detection of curved surface components to be tested 800, but can also be used for insulation resistance detection of flat components to be tested 800. By designing the insulation resistance detection auxiliary device 10 into different sizes, tiny electronic components (components to be tested 800) or large electronic components can also be detected. The first preset length is the length of the detection contact sheet 110 rolled up by the first roller 121, which can be designed according to the use environment and the size of the component to be tested 800. The second preset length is the length that the detection contact sheet 110 needs to be extended when the detection contact sheet 110 is completely in contact with the curved surface. Therefore, the first preset length is greater than the second preset length. The insulation resistance detection auxiliary device 10 disclosed in the present invention is used to replace the insulation resistance detection auxiliary device 10 (also called test lead) in the related art. During use, the insulation resistance detection auxiliary device 10 is placed on a curved surface (the element to be tested 800) and pressed downward. The detection contact piece 110 generates pressure due to the curved surface. At this time, the detection contact piece 110 bends. When the first roller 121 releases the detection contact piece 110 of the second preset length, the detection contact piece 110 is completely attached to the curved surface until the first mounting assembly 120, the detection contact piece 110 and the detection contact piece 110 are completely attached to the curved surface. The second mounting components 130 all contact the curved surface, forming a "surface" to "surface" detection, which solves the problem in the related technology that the test lead easily scratches the surface of the component to be tested 800, and prevents the problem of "point" to "surface" under high voltage causing electric sparks to damage the component to be tested 800. It can also make the minimum insulation resistance between "surfaces" more accurate, avoiding measurement errors caused by different pressures and poor surface contact during the detection process. The insulation resistance detection auxiliary device 10 disclosed in the present invention has a simple structure and is easy to operate. It can ensure the accuracy of the test while adapting to the components to be tested with different detection diameters.
