Description

TECHNICAL FIELD

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

[0002] The insulation performance of modern electrical equipment directly affects the operation performance of the whole machine and the safety and stability of the power system, and good insulation is the premise for ensuring the normal operation of electrical equipment and electrical circuits. Insulating sleeves, as typical insulating structural components with strong electric field distribution, are used in conjunction with high-voltage electrical equipment. In recent years, the use of rubber composite insulating sleeves has increased dramatically, but due to different manufacturing processes and materials of different manufacturers, there is a large gap in product quality. Insulating sleeves often have defects such as glue protrusion, staple connection, torsional deformation, and knotting when leaving the factory. However, the detection of defects in insulating sleeves currently relies on manual sorting in the packaging process after cutting to a fixed length, resulting in serious waste of sleeves and low sorting efficiency, and often missing defects.

[0003] To solve the above technical problems, the prior art proposes a scheme of detecting defects before packaging the sleeve, application number CN202311863651.9 (Traction type sleeve processing all-in-one machine), which detects defects by setting a movable clasp. When the outer diameter of the sleeve is too large or knotted and twisted, the sleeve drives the clasp to move forward, so that the sensor cannot detect the clasp. The deviation of the clasp is used to judge whether the size of the sleeve is too large. However, if the sleeve diameter decreases due to bending, the clasp cannot be moved, resulting in missed detection. Moreover, the clasp relies on spring rebound, which cannot continuously detect the defects of the sleeve during the transmission before the clasp rebounds, and cannot locate the length of the defects, making it difficult to determine the length of the defects that need to be cut. SUMMARY

[0036] The application will be further clarified by the following examples, which should be considered as merely illustrative of the present application and not in limitation of the present application, with reference to the appended drawings, in which:

[0037] As Figures 1-3As shown, the application provides an insulation sleeve loading detection device, which comprises a loading module 100, a conveying module 200 and a detection module 300. The loading module 100 conveys the sleeve to the conveying module 200, and the product defects are detected by the detection module 200, and then conveyed to the next process by the conveying module 200. The loading module 100 is located at the front end of the device, which mainly completes the batch continuous loading work of the product. In the loading process, it can realize the receiving prompt without the help of manual supervision, greatly increasing the automation degree of the loading process. The conveying module 200 is located on the left side of the loading module 100 and on both sides of the detection module 300, which is equivalent to the bridge between the loading module 100 and the detection module 300, so that the sleeve is more accurately and quickly conveyed. The conveying module 200 mainly comprises a conveying table 21, a guide seat 22, a porcelain eye 23, a compression conveying assembly 24, and a guide piece arranged at multiple positions. The guide piece comprises a line separation plate 25, and a plurality of porcelain eyes 23 are arranged on the line separation plate 25 along the length direction. The conveying table 21 is located on the left side of the loading module 100 and is mainly used to carry the conveying module 200 and the detection module 300. The guide seat 22 is located above the rightmost end of the conveying table 21, and the height is parallel to the line separation plate 25, which ensures that the sleeve from the loading module 100 is stably conveyed to the compression conveying assembly 24 and is mainly used to protect the sleeve. The porcelain eye 23 is located inside the guide seat 22 and the line separation plate 25, providing a channel for the sleeve conveying. The compression conveying assembly 24 is distributed on the left and right sides of the detection module 300 and is the main power of the sleeve in the conveying module 200. The line separation plate 25 is located below the front and rear ends of the connecting plate 15, on the right side of the compression conveying assembly 24, and on both sides of the middle part of the detection module 200, and is internally provided with a plurality of porcelain eyes 23, which facilitates the segmentation of the sleeve conveying channel. The detection module 300 is located between the two compression conveying assemblies 24 and is mainly used to detect the defects of the sleeve, such as glue protrusion, knot, twisting and bending, and receiving staple. The internal conveying process can detect the defects on the upper and lower surfaces of the sleeve, eliminating the blind area of defect detection. The detection module 300 comprises a scale 31, a lower assembly 32 and an upper assembly 33. The scale 31 is located on the side of the lower assembly 32 and is mainly used to determine the position of the defect and the length of the adjacent two defects. Determining the position of the defect can achieve accurate cutting of the sleeve, and determining the length of the adjacent two defects can be used to judge whether the interval distance of the defects meets the length required by product packaging. If not, cutting is performed at both ends of the two defects, and if it does, cutting is performed at both ends of each defect, which maximizes the avoidance of material waste and saves production cost. The lower assembly 32 is located below the upper assembly 33 and is mainly used to install various detection components, so that the detection module 300 moves stably on the conveying table 21 according to whether there is a defect, and the conveying distance of the defective sleeve is shortened. The upper assembly 33 is the most important component of the detection module 300 and is mainly used to detect various defects of the sleeve.

The lower end of the compression wheel fixing frame 142 is fixed on the pay-off stand 11, and one end is suspended below the tray 13. The upper and lower plates are connected by the elastic structure 144, which is mainly used for installing the compression wheel 141 and the sensor 143. The sensor 143 is located on the side of the compression wheel fixing frame 143 and is mainly used for detecting the position of the upper plate of the compression wheel fixing frame 143 to determine whether to start the alarm to remind the receiving.

The rubber-coated wheel 244 is located inside the rubber-coated wheel fixing seat 245 and is mainly used to convey the sleeve. The rubber-coated wheel fixing seat 245 is located below the cylinder 246 and is mainly used to load the rubber-coated wheel 244. The cylinder 246 is located above the cylinder base plate 247 and is mainly used to control the downward movement of the rubber-coated wheel fixing seat 245 to convey the sleeve.

[0041] The method for detecting the sleeve defects by using the detection module 300 can detect all defects on the upper and lower surfaces of the sleeve. The defects on the single surface of the sleeve will change the diameter of the sleeve. Therefore, by arranging the upper and lower displacement sensors 334, the displacement changes of the upper and lower surfaces of the sleeve when the sleeve is conveyed by the rubber coating roller 331 can be detected, thereby eliminating the detection blind area of the sleeve. In addition, the metal defects will pass through the sleeve, so by arranging a proximity sensor 332, all metal defects can be detected. The detection method of the detection module 300 is described as follows: the sleeve is conveyed by the compression conveying assembly 24 to the right porcelain eye 23, and then to the right rubber coating roller 331. The sleeve reaches the upper rubber coating roller 331 through the groove of the right rubber coating roller 331. If the upper displacement sensor 334 moves, it proves that there is a defect on the upper surface of the sleeve. When the sleeve is conveyed 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 the sleeve reaches the lower rubber coating roller 331, if the lower displacement sensor 334 moves, it proves that there is a defect on the lower surface of the sleeve. Finally, the sleeve passes through the left porcelain eye 23 and leaves the detection module 300 through the left rubber coating roller 331. This detection method can detect various defects of the sleeve without affecting the conveying of the sleeve. Since the detection sensor does not have any rebound movement parallel to the conveying stroke, the defects at each position of the sleeve can be detected.
