Abstract
Description
Technical Field
[0001] The present invention particularly 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 being placed on the performance of enameled wire. Since the performance of enameled wire is closely related to the insulating varnish, these new requirements are largely related to the performance of the insulating varnish. The adhesion of the insulating varnish is a key indicator of its quality. Only with good adhesion can the insulating varnish effectively prevent leakage in the enameled wire. Existing enameled wire, after being twisted, has low stability in high temperature or mechanical stress environments, causing the enameled wire to peel or deform during use, thereby reducing 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, which has low production efficiency.
[0004] Existing enameled wire production equipment does not have a systematic enameled wire adhesion test device. Manual sampling is usually used, but it is unable 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.

[0026] A method for testing a hot air adhesion test device for enameled wire detection, comprising the following steps:
[0027] S1. Preparation:
[0028] S1-1. Ensure that the enameled wire samples are ready and meet the test requirements;
[0029] 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, which drive the mold top-loading rollers on the U-shaped plate toward the mold top-loading outer groove sleeve, allowing the mold top-loading shaft to move. Cooperating with the mold winding mechanism, it abuts the winding mold. The winding mold is then pushed toward the mold winding mechanism and secured. Simultaneously, the core rod drive cylinder extends and drives the movable plate, thereby pushing the core rod outer groove sleeve, driving the core rod out and inserting it into the winding mold for installation and reinforcement.
[0030] S1-3. Ensure that the hot air adhesion tester is in normal working condition and is calibrated;
[0031] S2. Sample Loading: The enameled wire is properly passed through the tensioning wire pulley, first winding pulley, second winding pulley, and outlet guide pulley of the lead frame. It then passes through the first and second wire guide pulleys and the wire strip with wire holes in the cycloid mechanism. The wire is then wound into the winding die between the die top loading mechanism and the die winding mechanism.
[0032] S3. Winding hot air treatment:
[0033] S3-1. Start the drive motor to drive the winding bobbin to rotate the fixed winding mold. 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.
[0034] S3-2. During the winding process, the hot air blower is started and the reciprocating drive cylinder is started at the same time. The reciprocating drive shaft moves the reciprocating plate. The reciprocating plate drives the L-shaped air outlet to heat the enameled wire during the winding process with hot air and observe the change in its adhesion.
[0035] S4. After the winding is completed, the hot air blower and the reciprocating drive cylinder are stopped first. The wire hook is then extended forward by the wire clamping cylinder to hook the enameled wire. The wire clamping cylinder then retracts the wire clamping hook to tighten the enameled wire. The enameled wire is then manually cut and wound around the wire clamping hook to prevent the enameled wire from retracting due to the tension. The mold top-loading cylinder is then controlled to drive the two mold top-loading guide columns to retract, driving the mold top-loading rollers on the U-shaped plate to pull back the mold top-loading outer groove sleeve, making the mold top-loading shaft movable. At the same time, the core rod drive cylinder is retracted to drive the movable plate, thereby pulling back the core rod outer groove sleeve to drive the core rod to withdraw the winding mold, thereby removing the winding mold with the enameled wire.
[0036] S5. Result Inspection: Remove the winding die and inspect the hot air adhesion of the enameled wire. Specific inspections may include: ensuring the overall adhesion of the enameled wire coils, ensuring the enameled wire film is not peeling or damaged, and recording the enameled wire's performance in the hot air environment.
[0037] S6. Data Recording and Analysis: Record test data, including test temperature, time, and actual performance of the enameled wire. Analyze the test results to assess whether the hot air adhesion of the enameled wire meets the requirements.
[0038] 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.
[0039] The beneficial effects of the present invention are as follows: the device can provide an accurate hot air environment to ensure the reliability of the enameled wire adhesion test, while reducing manual intervention and improving test efficiency and consistency. In addition, the hot air temperature is adjustable to simulate different actual application scenarios and follow standardized test steps to ensure the repeatability and comparability of the test results.

A mold top-mounted outer groove sleeve 37 is mounted on the mold top-mounted shaft 36 and cooperates with the U-shaped plate 34, and an arc-shaped pressure plate 38 is fixed to the end of the mold top-mounted shaft 36 by bolts. Specifically, the mold top-mounted shaft 36 is assembled with the U-shaped assembly seat 2 by passing through the sliding sleeve 22, and the mold top-mounted roller 35 is located in the groove of the mold top-mounted outer groove sleeve 37. The two mold top-mounted guide columns 33 are driven to move by the mold top-mounted cylinder 32, thereby driving the mold top-mounted roller 35 on the U-shaped plate 34 to push and pull the mold top-mounted outer groove sleeve 37, so that the mold top-mounted shaft 36 is movable and cooperates with the mold winding mechanism 4 to abut against the winding mold.
[0054] The mold winding mechanism 4 includes a support frame 41 with bearings fixedly mounted on the detection workbench 1 and the U-shaped assembly seat 2, a drive motor 42 located below the support frame 41 and fixedly mounted on the detection workbench 1, a winding bobbin 43 passing through the support frame 41 and the U-shaped assembly seat 2 in sequence, a core rod 44 for inserting the mold, which extends to the U-shaped assembly seat 2 after passing through the winding bobbin 42, a core rod outer groove sleeve 45 mounted on the end of the core rod 44 close to the drive motor 42, an assembly column 46 welded to the outside of the support frame 41, a core rod driving cylinder 47 fixedly mounted on the assembly column 46, a movable plate 48 mounted on the assembly column 46 and connected to the output end of the core rod driving cylinder 47, and a core rod push-pull roller 49 mounted on the inner side of the movable plate 48 through a C-shaped frame and cooperating with the core rod outer groove sleeve 45.

Specifically, after the matching connecting piece 58 of the wire plate 59 is fixedly installed, the circular washer 561 is used to support the wire plate 59. At the same time, bolts are screwed in to further tighten the wire plate 59 and the push plate 56. This can prevent the wire plate 59 from vibrating during use and affecting the conveying effect.
[0060] The middle portion of the wire plate 59 is provided with a through hole 591 corresponding to the circular washer 561, which facilitates screwing in bolts to further tighten the wire plate 59 and the push plate 56;

8. A method for testing the hot air adhesion test device for enameled wire inspection according to any one of claims 1 to 7, 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, which drive the mold top-loading rollers on the U-shaped plate toward the mold top-loading outer groove sleeve, allowing the mold top-loading shaft to move. Cooperating with the mold winding mechanism, it abuts the winding mold. The winding mold is then pushed toward the mold winding mechanism and secured. Simultaneously, the core rod drive cylinder extends and drives the movable plate, thereby pushing the core rod outer groove sleeve, driving the core rod out and inserting it into the winding mold for installation and reinforcement. S1-3. Ensure that the hot air adhesion tester is in normal working condition and is calibrated; S2. Sample Loading: The enameled wire is properly passed through the tensioning wire pulley, first winding pulley, second winding pulley, and outlet guide pulley of the lead frame. It then passes through the first and second wire guide pulleys and the wire strip with wire holes in the cycloid mechanism. The wire is then wound into the winding die between the die top loading mechanism and the die winding mechanism. S3. Winding hot air treatment: S3-1. Start the drive motor to drive the winding bobbin to rotate the fixed winding mold. 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 and the reciprocating drive cylinder is started at the same time. The reciprocating drive shaft moves the reciprocating plate. The reciprocating plate drives 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 drive cylinder are stopped first. The wire hook is then extended forward by the wire clamping cylinder to hook the enameled wire. The wire clamping cylinder then retracts the wire clamping hook to tighten the enameled wire. The enameled wire is then manually cut and wound around the wire clamping hook to prevent the enameled wire from retracting due to the tension. The mold top-mounting cylinder is then controlled to retract the two mold top-mounting guide columns, driving the mold top-mounting rollers on the U-shaped plate to pull back the mold top-mounting outer groove sleeve, making the mold top-mounting shaft movable. At the same time, the core rod drive cylinder is retracted to drive the movable plate, thereby pulling back the core rod outer groove sleeve to drive the core rod to withdraw the winding mold, thereby removing the winding mold with the enameled wire. S5. Result Inspection: Remove the winding die and inspect the hot air adhesion of the enameled wire. Specifically, the inspection includes: ensuring the enameled wire coils are firmly bonded and free of loose wires; ensuring the enameled wire film is not peeling or damaged; and recording the enameled wire's performance in the hot air environment. S6. Data Recording and Analysis: Record test data, including test temperature, time, and actual performance of the enameled wire. Analyze the test results to assess 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.
