Description

Technical Field

[0001] This utility model relates to the field of wire and cable testing equipment, and in particular to a testing device based on the metering mark of pinhole insulation breakage by a high-frequency spark tester. Background Technology

[0002] A high-frequency spark tester is an online testing device placed on the winding section of wire and cable products during production. Its main function is to use frequency and voltage to detect whether the wire and cable products have copper leakage, broken insulation, surface impurities, insulation withstand voltage, etc. The spark tester applies a set voltage value to the insulated wire periodically according to a certain pattern, while the conductor is grounded. This creates a voltage difference between the conductor and the insulation surface, which can detect whether there are defects in the insulation layer, ensuring that the wire and cable products are qualified for shipment.

[0003] For example, the prior art patent application with publication number CN216485344U includes a spark testing machine body and a housing. The housing is mounted on the spark testing machine body, and a cover is hinged to the surface of the housing. Openings are located on both sides of the housing, and a support plate is installed inside the housing near the opening. Through the cooperation of the top plate and the bead chain, the cable awaiting testing enters the housing through one side opening, passes through multiple bead chains, and is tested by the spark testing machine body. If beads fall off or the bead chain breaks after prolonged use, it needs to be replaced. During replacement, the spark testing machine body is in a closed, non-operating state. Through the cooperation of the baffle and the groove, and the cooperation of the connecting structure and the bead chain, the housing cover is opened, the baffle is removed, exposing the groove, and the damaged bead chain is removed and replaced through the connecting structure. This design offers greater flexibility and convenience.

[0004] However, these devices have obvious functional defects: they can only detect whether there are defects in the cable, but cannot accurately locate the defect or record the data. When a defective cable is detected, the staff has to manually check the specific location of the defect, which is not only time-consuming and laborious, but also prone to missed detection and misjudgment. Furthermore, when multiple bead chains need to be replaced later, the user has to first remove the baffle, then take out the base plate, and only then can the bead chain be removed from the base plate. The operation is cumbersome and reduces the efficiency of maintaining the high-frequency EDM machine.

[0005] Therefore, it is necessary to provide a new and innovative technology, a detection device based on the pinhole penetration of meter markers by a high-frequency spark machine. Utility Model Content

Detailed Implementation

[0030] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0031] First Embodiment

[0032] Please refer to the following: Figure 1 , Figure 2 , Figure 3 ,in, Figure 1 A schematic diagram of the structure of a first embodiment of a detection device based on a high-frequency spark machine pinhole puncture meter mark provided by this utility model; Figure 2 for Figure 1 The diagram shown is a structural block diagram of the control module. Figure 3 for Figure 1 The diagram shown is a structural block diagram of the meter marking module.

[0033] A detection device based on pinhole insulation breakage marking in a high-frequency spark test includes: a dual-channel high-frequency high-voltage generation module, a dual-channel discharge detection module, a marking module, a control module, and an AD voltage sampling feedback module. The dual-channel high-frequency high-voltage generation module is connected to the dual-channel discharge detection module and generates a 2.5kHz-6kHz sinusoidal high voltage for detection. The AD voltage sampling feedback module is connected to the dual-channel high-frequency high-voltage generation module, the dual-channel discharge detection module, and the control module. The dual-channel discharge detection module contains two independent beaded electrode assemblies that synchronously discharge and detect the tested wires and cables in parallel. The marking module tracks the cable transport speed, marks the location of pinhole insulation breakage defects in the cable insulation layer, and stores the data. The control module is connected to the dual-channel high-frequency high-voltage generation module, the dual-channel discharge detection module, and the marking module to adjust the discharge parameters and marking timing.

[0034] The distance between the two electrode components of the dual-channel discharge detection module is adjustable, and each is equipped with an independent discharge control and current and voltage detection feedback circuit, which can adjust the discharge voltage and current threshold independently to adapt to the detection of cables of different specifications.

[0035] The dual-path parallel detection design improves detection coverage and reliability, and avoids missing detection of a single electrode assembly.

[0036] The meter marking module includes a high-speed multi-turn absolute encoder, a marking execution unit, and a data storage unit. The encoder collects cable speed and displacement data. The marking execution unit can select inkjet, laser, or mechanical imprinting methods for marking. The marking content includes meter value, detection time, and defect type. The data storage unit records the marking information for querying.

[0037] The encoder collects cable conveying speed and displacement in real time, accurately calculating the meter position when a defect occurs; the marking execution unit can select the marking method according to production needs, and the marking content is intuitive and easy to understand; the data storage unit records all defect information, supporting subsequent traceability and quality analysis, and avoiding missed detections and misjudgments.

[0038] The control module has a built-in 32-bit microcontroller and PID adaptive algorithm circuit, and the AD voltage sampling feedback module is used for feedback voltage circuit.

[0039] The 32-bit microcontroller has a fast processing speed and can quickly respond to detection signals and control commands; the PID adaptive algorithm enables precise control of discharge parameters, automatically optimizing voltage and current parameters according to cable specifications and detection status, ensuring detection accuracy and stability.

[0040] The working principle of the detection device based on the pinhole penetration of the meter mark in a high-frequency spark tester provided by this utility model is as follows:

[0041] By setting detection parameters such as discharge voltage and current threshold through the control module, the dual-channel high-frequency high-voltage generation module generates a 2.5kHz-6kHz sinusoidal high voltage to supply voltage to the dual-channel discharge detection module; during the cable production process, the cable passes through the dual-channel beaded electrode assembly of the dual-channel discharge detection module and begins online detection;

[0042] When the cable insulation layer has defects such as copper leakage, broken skin, or surface impurities, a voltage difference is formed between the electrode assembly and the cable conductor, generating a discharge breakdown signal. The current detection circuit of the dual-channel discharge detection module captures the signal and transmits it to the control module.

[0043] The control module triggers the meter marking module, the encoder collects the cable displacement data (meter value) at this time, the marking execution unit marks the defect location with inkjet, laser or mechanical imprint, and records the detection time and defect type at the same time; the data storage unit saves all marking information for subsequent query and traceability;

[0044] During the testing process, the control module optimizes the discharge parameters in real time through a PID adaptive algorithm. If different specifications of cables need to be tested, the spacing between the dual-electrode components can be adjusted, and the discharge parameters of each component can be adjusted individually to ensure test compatibility.

[0045] Compared with related technologies, the detection device based on the pinhole penetration of meter markers in a high-frequency spark tester provided by this utility model has the following advantages:

[0046] The system utilizes a combination of a dual-channel high-frequency high-voltage generator module, a dual-channel discharge detection module, a meter-counting and marking module, and a control module. During cable inspection, the dual-channel high-frequency high-voltage generator module provides a stable sinusoidal high voltage, while the dual-channel discharge detection module performs parallel and synchronous discharge detection. When a defect is detected, the meter-counting and marking module automatically collects cable displacement data and completes meter marking, eliminating the need for manual inspection and location. The control module adjusts the discharge parameters and marking timing, and the data storage unit records defect information for subsequent retrieval. This solves the problems of difficult location of pinhole damage defects in cable insulation and lack of data recording, significantly reducing manual operation, improving inspection accuracy and efficiency, and ensuring the quality of cables leaving the factory.

[0056] In another optional embodiment, the detection device based on the pinhole puncture and meter mark of the high-frequency EDM machine may not include the dual-channel high-frequency high-voltage generation module, dual-channel discharge detection module, meter mark module and control module. It is only necessary to satisfy that it does not hinder the other components of the detection device based on the pinhole puncture and meter mark of the high-frequency EDM machine, so as to enable the rapid replacement of the detection component 6.
