Description

Technical Field

[0001] The invention specifically relates to a hot air adhesion testing device for enameled wire detection and a testing method thereof. Background Art

[0002] With the development of motor 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 the insulating paint, these new requirements are largely related to the performance of the insulating paint. Among them, the adhesion of the insulating paint is an important indicator of the quality of the insulating paint. Only when the insulating paint has good adhesion can it better prevent the leakage of the enameled wire. After the existing enameled wire is twisted, the stability is low in high temperature or mechanical stress environment, causing the enameled wire to peel or deform during use, thereby reducing the electrical performance and durability. Affecting the long-term reliability and performance of electronic equipment.

[0003] The adhesion is provided by self-adhesive paint, which is different from insulating paint. The description here is recommended to be changed to: Self-adhesive enameled wire is increasingly used in the electronic equipment industry due to its rapid one-piece molding characteristics. Among them, the adhesion of the enameled wire is an important indicator of the quality of the self-adhesive enameled wire. Only when the self-adhesive paint has good adhesion can it better bond and form during the rapid winding process and be directly installed. The existing enameled wire needs to be plastic-sealed after winding and fixing, and the production efficiency is low.

[0004] There is no systematic enameled wire adhesion testing equipment in the existing enameled wire production equipment. Manual sampling operations are usually used, but it is impossible to use an accurate hot air environment to ensure the reliability of the enameled wire adhesion test. In addition, there is a lot of manual intervention, which cannot improve the test efficiency and test consistency, and cannot guarantee the repeatability and comparability of the test results.

Place the winding mold between the mold top loading mechanism and the mold winding mechanism, control the mold top loading cylinder to drive the two mold top loading guide columns to drive the mold top loading rollers on the U-shaped plate to push toward the mold top loading outer groove sleeve, so that the mold top loading shaft moves, cooperate with the mold winding mechanism to abut against the winding mold, push the winding mold toward the mold winding mechanism and fix it, and at the same time extend the core rod driving cylinder to drive the movable plate, thereby pushing the core rod outer groove sleeve to drive the core rod to be ejected and inserted into the winding mold for installation and reinforcement;

[0030] S1-3. Ensure that the hot air adhesion test device is in normal working condition and perform necessary calibration;

[0031] S2. Loading the sample: The enameled wire is correctly passed through the tensioning wire wheel, the first winding wheel, the second winding wheel and the outlet guide wheel of the wire rack, and then correctly passed through the first inlet guide wheel, the second inlet guide wheel and the wire strip with wire holes in the cycloid mechanism, and then wound in the winding mold between the mold top loading mechanism and the mold winding mechanism;

10. A testing method for the hot air adhesion testing device for enameled wire detection according to claims 1-9, characterized in that: The following steps are involved: S1. Preparation: S1-1. Ensure that the enameled wire samples are ready and meet the test requirements; S1-2. Place the winding mold between the mold top loading mechanism and the mold winding mechanism, control the mold top loading cylinder to drive the two mold top loading guide columns to drive the mold top loading rollers on the U-shaped plate to push toward the mold top loading outer groove sleeve, so that the mold top loading shaft moves, cooperate with the mold winding mechanism to abut against the winding mold, push the winding mold toward the mold winding mechanism and fix it, and at the same time extend the core rod driving cylinder to drive the movable plate, thereby pushing the core rod outer groove sleeve to drive the core rod to be ejected and inserted into the winding mold for installation and reinforcement; S1-3. Ensure that the hot air adhesion test device is in normal working condition and perform necessary calibration; S2. Loading the sample: The enameled wire is correctly passed through the tensioning wire wheel, the first winding wheel, the second winding wheel and the outlet guide wheel of the wire rack, and then correctly passed through the first inlet guide wheel, the second inlet guide wheel and the wire strip with wire holes in the cycloid mechanism, and then wound in the winding mold between the mold top loading mechanism and the mold winding mechanism; S3. Winding hot air treatment: S3-1. Start the drive motor to drive the winding shaft to drive the fixed winding mold to rotate, and at the same time, the cycloid drive cylinder drives the push plate to drive the wire plate to reciprocate, which can swing the copper wire to make it neat and tight; S3-2. During the winding process, the hot air blower is started to work, and the reciprocating drive cylinder is started at the same time, driving the reciprocating drive shaft to move the reciprocating plate, and the reciprocating plate is used to drive the L-shaped air outlet to heat the enameled wire during the winding process with hot air, and observe the change in its adhesion; S4. After the winding is completed, the hot air blower and the reciprocating driving cylinder are stopped first, and then the wire hook is driven by the wire hook cylinder to extend forward to hook the enameled wire, and then the wire hook is driven by the wire hook cylinder to retract and tighten the enameled wire. At this time, the enameled wire is cut manually, and the cut enameled wire can be wound around the wire hook to prevent the enameled wire from retracting due to the tension. Then the mold top-loading cylinder is controlled to drive the two mold top-loading guide columns to retract and drive the mold top-loading roller on the U-shaped plate to pull back the mold top-loading outer groove sleeve, so that the mold top-loading axis, at the same time, the core rod driving cylinder is retracted to drive the movable plate, so as to pull back the core rod outer groove sleeve to drive the core rod to withdraw the winding mold, thereby taking out the winding mold with enameled wire; S5. Check the results: Take out the winding mold and check the hot air adhesion of the enameled wire. The specific inspection contents may include: whether the enameled wire coil is firmly bonded as a whole and does not loosen, whether the enameled wire film is peeling off or damaged, and record the performance of the enameled wire in the hot air environment; S6. Data recording and analysis: record the test data, including the test temperature, time and actual performance of the enameled wire, and analyze the test results to evaluate whether the hot air adhesion of the enameled wire meets the requirements; S7. Cleaning and maintenance: After completing the test, clean the equipment to ensure it is in good condition before the next test, and perform equipment maintenance regularly to ensure long-term stable operation.
