Embodiment Construction

[0029] see figure 1 and figure 2 , in the embodiment of the present invention, a kind of inspection method for the production of insulating varnish for enameled wire, comprises adhesion detection method and hardness detection method, and adhesion detection method comprises the following steps:

[0030] S1. Select the substrate board 1 with the same enameled wire material, and make the substrate board 1 fixed;

[0031] S2. According to the production process of the enameled wire, evenly spray the insulating varnish 2 on the base plate 1, and perform drying treatment;

[0032] S3. Spread the strong adhesive 3 evenly on the insulating paint 2. Before the initial setting of the strong adhesive 3, press the bottom end of the connecting rod 4 to the strong adhesive 3. Through the strong adhesive 3, connect the connecting rod 4 with the strong adhesive 3. The insulating paint 2 is firmly bonded together, and the strong adhesive 3 can be epoxy resin adhesive or quick-drying cyanoac...

Abstract

The invention relates to the technical field of insulating paint detection. The invention discloses an inspection method for the production of insulating paint for enameled wires. The method comprisesan adhesive force detection method and a hardness detection method, and the adhesive force detection method comprises the following steps: S1, selecting a base material plate, S2, spraying insulatingpaint, S3, smearing a strong adhesive, and installing a connecting rod, S4, installing a tension sensor and a cylinder, S5, cutting the strong adhesive and the insulating paint, and S6, carrying outa tensile test. The hardness detection method comprises the following steps: S1, fixing the base material plate sprayed with the insulating paint in a positioning jig; S2, installing a pencil; S3, adjusting the positions of the pencil and an oscillating rod; S4, adding the weight; and S5, drawing a line. According to the invention, the adhesive force of the insulating paint can be accurately measured by pulling the insulating paint through the tension sensor, and the hardness of the insulating paint can be accurately measured by changing the pressure of the nib of the pencil pressed on the insulating paint and driving the positioning jig to move horizontally through the motor.

Description

technical field [0001] The invention relates to the technical field of insulating varnish detection, in particular to an inspection method for the production of insulating varnish for enameled wires. Background technique [0002] With the development of electrical and electrical products, more and more new requirements are put forward for the performance of enameled wire. Since the performance of enameled wire is inseparable from insulating varnish, these new requirements are largely related to the performance of insulating varnish. Among them, The adhesion and hardness of the insulating varnish are important indicators of the quality of the insulating varnish. Only when the insulating varnish has good adhesion and hardness can it better prevent the leakage of enameled wires. [0003] In the existing technology, there are various methods to test the performance of insulating varnish, and the means of testing are also different, but the accuracy of the test is generally not h...
