[0001] The invention relates to the technical field of enameled wire paint film detection, and in particular to an enameled wire paint film damage online detection method. Background Art

[0002] Enameled wire is a main type of winding wire, consisting of a conductor and an insulating layer. The bare wire is annealed and softened, then painted multiple times and baked. After processing, the paint film of the enameled wire needs to be tested by a detection device.

[0003] Some existing enameled wires are inspected by a detection mechanism during inspection. When the detection mechanism detects that the paint film is damaged, the operator needs to mark the broken position. After the operator has finished marking, the device needs to be restarted to continue inspecting the enameled wire. Therefore, the enameled wire is more troublesome to inspect. Summary of the invention

[0004] In order to improve the problem that some of the enameled wires mentioned above are inspected by a detection mechanism, when the detection mechanism detects that the paint film is damaged, the operator needs to mark the broken position, and when the operator completes the marking, the device needs to be restarted to continue to detect the enameled wire, so the enameled wire is more troublesome during detection. The present invention provides an online detection method for paint film damage of enameled wire.

[0005] The present invention provides an online detection method for enameled wire paint film damage, which adopts the following technical solution:

[0007] Step S1, conveying the enameled wire through a conveying mechanism, and the enameled wire passes through a ring-shaped detection mechanism during conveyance;

[0008] Step S2, performing a full-scale inspection on the paint film of the enameled wire through the annular inspection mechanism to determine whether the paint film is damaged, and transmitting the inspection data to the controller;

[0009] Step S3: When the annular detection mechanism detects that the paint film is damaged, the controller controls the conveying mechanism to stop running;

[0010] Step S4: the controller controls the alarm mechanism to operate to warn the operator;

[0011] Step S5, the controller controls the marking mechanism to move on the enameled wire to mark, and after the marking is completed, the marking mechanism is reset, and the controller controls the alarm mechanism to stop operating;

[0012] Step S6: When the marking mechanism is reset, the conveying mechanism continues to operate and convey the enameled wire, and the paint film of the enameled wire continues to be detected by the annular detection mechanism.

[0013] The above technical solution facilitates online detection of paint film damage of enameled wires.

[0014] Optionally, in the above-mentioned online detection method for paint film damage of enameled wire, the conveying mechanism includes a winding device and an unwinding device.

[0016] Optionally, in the above-mentioned online detection method for paint film damage of enameled wire, the annular detection mechanism includes an assembly ring and a plurality of infrared rangefinders, and the plurality of infrared rangefinders are distributed in a ring shape at equal distances on the inner side of the assembly ring, and the enameled wire is interspersed on the inner side of the assembly ring and coincides with the central axis of the assembly ring.

[0017] The above technical solution makes it easy to detect the enameled wire while it is being transported.

[0018] Optionally, in the above-mentioned online detection method for paint film damage of enameled wire, a detection threshold is pre-set in the controller. When the detection value of the annular detection mechanism is greater than the detection threshold, it indicates that the paint film of the enameled wire is damaged. At this time, the controller operates and controls the alarm mechanism and the marking mechanism to operate, and at the same time the controller controls the conveying mechanism to stop operating.

[0019] Through the above technical solution, the controller can conveniently analyze the data detected by the ring detection mechanism, and conveniently control the alarm mechanism, the marking mechanism and the conveying mechanism.

[0022] Optionally, in the above-mentioned online detection method for paint film damage of enameled wire, the marking mechanism includes an electric push rod and a marking pen, and the marking pen is arranged at the protruding end of the electric push rod.

[0023] Through the above technical solution, it is convenient to mark the damaged part of the paint film of the enameled wire with a marking pen, so that it is convenient for subsequent operators to find the damaged part.

[0024] In summary, the present invention includes at least one of the following beneficial effects: 1. When the annular detection mechanism detects that the paint film is damaged, the controller controls the marking mechanism to operate, so that the damaged part of the paint film of the enameled wire is marked by the marking mechanism, thereby facilitating subsequent operators to find and process the damaged part of the paint film, and making it more convenient to detect the enameled wire;

[0025] 2. After the marking of the damaged part of the paint film is completed, the marking mechanism is reset. At this time, the conveying mechanism restarts to convey and detect the enameled wire, thereby facilitating the increase of the detection efficiency of the enameled wire. BRIEF DESCRIPTION OF THE DRAWINGS

[0026] Figure 1 It is a schematic diagram of the process of the present invention. DETAILED DESCRIPTION

[0027] The following is combined with Figure 1 The present invention is described in further detail.

[0028] Please refer to the attached figure in the instruction manual Figure 1 An embodiment provided by the present invention is an online detection method for damage to an enameled wire paint film, comprising the following steps:

[0029] Step S1, conveying the enameled wire through a conveying mechanism, and the enameled wire passes through a ring-shaped detection mechanism during conveyance;

[0030] Step S2, performing a full-scale inspection on the paint film of the enameled wire through the annular inspection mechanism to determine whether the paint film is damaged, and transmitting the inspection data to the controller;

[0031] Step S3: When the annular detection mechanism detects that the paint film is damaged, the controller controls the conveying mechanism to stop running;

[0032] Step S4: the controller controls the alarm mechanism to operate to warn the operator;

[0033] Step S5, the controller controls the marking mechanism to move on the enameled wire to mark, and after the marking is completed, the marking mechanism is reset, and the controller controls the alarm mechanism to stop operating;

[0034] Step S6: When the marking mechanism is reset, the conveying mechanism continues to operate and convey the enameled wire, and the paint film of the enameled wire continues to be detected by the annular detection mechanism.

[0035] See the attached drawings in the specification Figure 1 The conveying mechanism includes a winding device and an unwinding device. The winding device is used to facilitate winding the enameled wire, and the unwinding device is used to facilitate unwinding the enameled wire, thereby realizing the conveyance of the enameled wire. The winding device and the unwinding device are both existing technologies.

[0036] See the attached drawings in the specification Figure 1 The annular detection mechanism includes an assembly ring and a plurality of infrared rangefinders. The plurality of infrared rangefinders are equidistantly distributed in an annular shape on the inner side of the assembly ring. The enameled wire is inserted into the inner side of the assembly ring and coincides with the central axis of the assembly ring. The central axis of the enameled wire coincides with the central axis of the assembly ring, so that the multiple infrared rangefinders in the assembly ring detect the same distance for the enameled wire. When the data detected by one of the infrared rangefinders changes, the surface paint film is damaged. The infrared rangefinder is a prior art.

[0037] See the attached drawings in the specification Figure 1 A detection threshold is pre-set in the controller. When the detection value of the annular detection mechanism is greater than the detection threshold, it indicates that the paint film of the enameled wire is damaged. At this time, the controller operates and controls the alarm mechanism and the marking mechanism to operate. At the same time, the controller controls the conveying mechanism to stop operating. By setting the detection threshold, it is convenient to analyze the data detected by the annular detection mechanism, so as to determine whether the paint film of the enameled wire is damaged. If the analysis structure is yes, the controller controls the conveying mechanism to stop operating, and then controls the alarm mechanism and the marking mechanism to operate. The controller is an existing PLC controller.

[0038] See the attached drawings in the specification Figure 1 The alarm mechanism includes a buzzer and a flashing light, which cooperate with the buzzer and the flashing light to warn the operator.

[0039] See the attached drawings in the specification Figure 1 The marking mechanism includes an electric push rod and a marking pen. The marking pen is arranged at the protruding end of the electric push rod. The electric push rod is controlled by a controller to move and push the marking pen to move, thereby causing the marking pen to contact with the enameled wire and mark it.

[0040] Working principle: When using the online detection method for paint film damage of enameled wire, the enameled wire is transported by the conveying mechanism, and the enameled wire passes through the annular detection mechanism during transportation and is detected, and the detection data is transmitted to the controller. When the annular detection mechanism detects that the paint film is damaged, the controller controls the conveying mechanism to stop running, and then controls the alarm mechanism and the marking mechanism to operate. When the marking mechanism is reset, the conveying mechanism continues to operate and conveys and detects the enameled wire.

[0041] The above are all preferred embodiments of the present invention, and are not intended to limit the protection scope of the present invention. Therefore, any equivalent changes made based on the structure, shape, and principle of the present invention should be included in the protection scope of the present invention.
