Description

Technical Field

[0001] The invention relates to the technical field of electrical equipment, and in particular to an insulating sleeve feeding detection device and a testing method thereof. Background Art

[0002] The insulation performance of modern electrical equipment directly affects the overall operating performance of the equipment and the safety and stability of the power system. Good insulation is a prerequisite for ensuring the normal operation of electrical equipment and electrical lines. Insulating sleeves are used in conjunction with high-voltage electrical equipment as insulating structural components with typical strong electric field distribution. In recent years, the use of rubber composite insulating sleeves has increased dramatically, but due to the different manufacturing processes and materials of different manufacturers, there is a large gap in product quality. Insulating sleeves often have defects such as rubber protrusions, stapler connections, torsional deformation, and knots when leaving the factory. However, the defect detection of insulating sleeves currently relies on manual sorting in the packaging process after fixed-length cutting, which results in serious sleeve waste and low sorting efficiency, and often misses.

[0003] In order to solve the above technical problems, the prior art proposes a solution for defect detection before casing packaging, and the application number is CN202311863651.9 (traction-type casing processing integrated machine). A movable clamping ring is set to detect defects. When the outer diameter of the casing is too large or knotted and twisted, the casing drives the clamping ring to move forward, so that the sensor cannot detect the clamping ring. The deviation of the clamping ring is used to judge whether the casing size is too large. However, if the casing is bent and the diameter of the casing becomes smaller, the clamping ring cannot be driven to move, and missed detection will occur. In addition, the clamping ring relies on spring rebound, and cannot continuously detect casing defects during the transmission process before the clamping ring rebounds. The length of the defect cannot be located, and it is difficult to determine the length of the defect that needs to be cut. Summary of the invention

[0004] Purpose of the invention: In view of the above problems, the purpose of the present invention is to provide an insulating sleeve feeding detection device, which can determine the position and length of defects during the detection process, facilitate fixed-point cutting in subsequent processes, eliminate material waste, improve the detection accuracy of the sleeve, avoid misdetection and missed detection, and ensure the safety of the sleeve.

[0041] The method for realizing casing defect detection using the detection module 300 can detect all defects existing on the upper and lower sides of the casing. Since defects existing on one side of the casing will cause the diameter of the casing to change, the displacement changes of the upper and lower sides of the casing when the casing is conveyed by the rubber-coated roller 331 can be detected by setting two upper and lower displacement sensors 334, thereby eliminating the detection blind area of ​​the casing. In addition, since metal defects will pass through the casing, a proximity sensor 332 is set to detect all metal defects. The detection method of the detection module 300 is described as follows: the compression conveying component 24 conveys the casing to the right rubber-coated roller 331 through the right porcelain eye 23, and the casing passes through the right rubber-coated roller 3 When the groove 31 reaches the upper rubber-coated roller 331, if the upper displacement sensor 334 moves, it proves that there is a defect on the upper side of the sleeve. When it is transmitted downward to the vicinity of the proximity sensor 332, if there is an alarm, it proves that there is a metal defect in the sleeve. When it reaches the lower rubber-coated roller 331, if the lower displacement sensor 334 moves, it proves that there is a defect on the lower side of the sleeve. Finally, it passes through the left porcelain eye 23 through the left rubber-coated roller 331 and leaves the detection module 300. This detection method does not affect the transmission of the sleeve while detecting multiple defects of the sleeve, because the detection sensor does not have any rebound movement parallel to the transmission stroke, and can detect defects at every position of the sleeve.

The top plate (337) is installed on the top of the lower component (32). Two sensor cylinders (336) are provided, one of which is installed on the inner bottom surface of the lower component (32) and the other is installed on the top plate (337). Two displacement sensors (334) are provided, which are respectively connected to the lower and upper sensor cylinders (336) through a displacement sensor fixing plate (335). The proximity sensor (332) is arranged between the two displacement sensors (334) and connected to the lower component (32) through the proximity sensor fixing plate (333).

9. The insulating sleeve feeding detection device according to claim 1, characterized in that: The guide member comprises a porcelain eye (23) and a separator plate (25), and a plurality of porcelain eyes (23) are arranged on the separator plate (25) at intervals along the longitudinal direction.

10. A method for testing a detection module of an insulating sleeve feeding detection device according to claim 8, characterized in that The following steps are involved: Step 1: Press the conveying assembly to convey the casing to the rubber-coated roller on one side of the upper assembly through the guide member; Step 2: The rubber-coated roller on this side continues to upload the casing to a rubber-coated roller above it; Step 3: The upper displacement sensor detects the casing. If the upper displacement sensor moves, it proves that there is a defect on the upper side of the casing. Otherwise, go to step 4; Step 4: The casing is continuously conveyed to a rubber-coated roller below. During the conveying process, it passes near the proximity sensor. If an alarm is given, it indicates that there is a metal defect in the casing. Otherwise, it proceeds to step 5. Step 5: The casing reaches the rubber-coated roller below. If the displacement sensor below moves, it proves that there is a defect on the lower side of the casing. Otherwise, it goes to step 6. Step 6: The sleeve is transferred to the rubber-coated roller on the other side, and leaves the inspection module through the rubber-coated roller to reach the next process.
