Description

Technical Field

[0001] The invention relates to the technical field of electromagnetic wire processing, in particular to a device for detecting the overlapping rate of an electromagnetic wire wrapped with a mica tape. Background Art

[0002] Mica wrapped electromagnetic wire is used for high-voltage motors, high-voltage high-frequency motors, wind turbines, etc. It has high breakdown voltage resistance, especially excellent high-frequency corona resistance and good process characteristics. With the rapid development of wind power generation and high-speed trains in my country, higher requirements are put forward for mica wrapped electromagnetic wire. The overlap rate of mica wrapped electromagnetic wire is an important factor affecting the voltage drop. In production, it is often encountered that the overlap rate is too large or too small, and even worse, it overlaps in one piece; if the mica overlap deviation is too large, the inter-turn insulation breakdown phenomenon will occur during the induction high-voltage test or the partial discharge test will not pass; if the mica overlap deviation is too small, the insulation thickness will increase and the motor size will become larger; although the overlap deviation will pass the induction high-voltage test and partial discharge test, when the mica wrapped electromagnetic wire is made into a coil and put into operation, the coil will burn out, and the consequences are very serious.

[0003] For example, the Chinese invention patent (application number: CN 103035342B) discloses a method and device for detecting and adjusting the overlap rate of electromagnetic wire wrapped with mica tape. Its specification discloses: The method for detecting and adjusting the overlap rate of electromagnetic wire in this application first starts a pulse generating device to drive a smart camera to take a photo containing a segment of electromagnetic wire image, and the segment of electromagnetic wire image has at least three overlapped seams: then the photo is sent to a processing device, and the processing device selects an image processing area on the photo, and the image processing area contains a segment of electromagnetic wire image with at least three overlapped seams; then the processing device determines the distance value between any two adjacent overlapped seams in a segment of electromagnetic wire image; compares the distance value with the distance threshold between two stored overlapped seams, and the distance value is not equal to the distance threshold and is between the minimum distance threshold and the maximum distance threshold.

[0004] The structure of the device currently on the market for detecting the overlap rate of electromagnetic wire wrapped with mica tape is relatively complex, and it is necessary to continuously drive the smart camera to shoot through pulse signals to realize the detection of the overlap rate. The pulse signal drive has a response deviation, which affects the quality and efficiency of the overlap rate detection. In addition, the traditional device for detecting the overlap rate of electromagnetic wire wrapped with mica tape does not have the ability to draw anti-counterfeiting lines, which is not conducive to the processing and production of electromagnetic wires. The above patent can prove the defects of the existing technology.

[0005] Therefore, we have made improvements on this and proposed a device for detecting the overlapping rate of mica tape wrapped electromagnetic wire. Summary of the invention

[0017] In the scheme of this application:

[0018] 1. The anti-counterfeiting inkjet pen can be used to draw lines on the mica tape wrapped around the electromagnetic wire, which plays an anti-counterfeiting role in the production of electromagnetic wire. The overlapping rate detection electric control box works with the intelligent camera to monitor and shoot the anti-counterfeiting lines on the mica tape in real time.

[0048] Example 2

[0049] like Figure 1 , Figure 3 , Figure 4 , Figure 5 and Figure 6 As shown, the device for detecting the overlap rate of mica tape wrapped electromagnetic wire provided in Example 1 is further optimized. Specifically, Figure 1As shown, the pneumatic pressing assembly 9 includes a mounting frame 901 fixed on the top outer wall of the wire holder 4, an end tube 902 is inlaid and installed on the top outer wall of the mounting frame 901, a piston 903 is arranged inside the end tube 902, a connecting rod 904 is fixed on the bottom outer wall of the piston 903, a spring 907 is sleeved on the outer wall of the connecting rod 904 located below the piston 903, and a fixing frame 905 is fixed on one end of the connecting rod 904 that passes through the outside of the end tube 902, and a rotating mounting frame 905 is arranged on the inner wall of the fixing frame 905.

During the process, the electromagnetic wire passes through the electromagnetic wire wrapping mechanism 3 for mica tape wrapping. The electromagnetic wire wrapped with mica tape passes above the wire holder 4. During the process, the compressed air generated by the operation of the first turbine pump 909 is input into the end tube 902 through the pump air pipe 910. The rising air pressure in the end tube 902 drives the piston 903 and the connecting rod 904 to move downward, thereby driving the fixing frame 905 and the wire pressing roller 906 to move downward, so that the wire pressing roller 906 is pressed and held at On the electromagnetic wire conveyed on the wire holder 4, the wire holder 4 and the wire pressing roller 906 cooperate to make the conveying of the mica tape wrapped electromagnetic wire more stable, effectively reducing the deviation of the subsequent mica tape overlapping rate detection.

When the air pressure in the end tube 902 reaches the threshold of the pressure relief valve 912, the excess air is input into the blowing head 1010 through the air inlet pipe 1012, the second turbine pump 1011 and the air delivery pipe 1013. The compressed air is blown out through the blowing head 1010 to blow dust off the electromagnetic wire that is not wrapped with mica tape. The air passes through the second turbine pump 1011. During the process, the second turbine pump 1011 will be driven to rotate, and the guide wheel 104 and the belt 105 will be driven to rotate through the transmission shaft 103. During the rotation of the insertion rod 109 on the belt 105, the guide ring 107 will be driven to move back and forth along the guide rod 106 through the guide frame 108, thereby driving the air blowing head 1010 to move back and forth, so that the air blowing head 1010 can comprehensively blow dust off the electromagnetic wire that is not wrapped with mica tape, thereby improving the quality of mica tape wrapping on the electromagnetic wire.

[0058] The use process of the device for detecting the overlap rate of mica tape wrapped electromagnetic wire provided by the present invention is as follows:

[0059] Working principle: During the operation of the electromagnetic wire wrapping machine, the electromagnetic wire is pulled and transported through the electromagnetic wire traction mechanism 2. During the process, the electromagnetic wire passes through the electromagnetic wire wrapping mechanism 3 for mica tape wrapping. The electromagnetic wire wrapped with mica tape passes over the wire holder 4. During the process, the compressed air generated by the operation of the first turbine pump 909 is input into the end tube 902 through the pump air pipe 910. The rising air pressure in the end tube 902 drives the piston 903 and the connecting rod 904 to move downward, thereby driving the fixing frame 905 and the crimping roller 906 to move downward, so that the crimping roller 906 is pressed on the electromagnetic wire transported on the wire holder 4. The wire holder 4 and the crimping roller 906 cooperate to make the transportation of the mica tape wrapped electromagnetic wire more stable. During the downward movement of the fixing frame 905, the mounting plate 908 also drives the anti-counterfeiting inkjet pen 5 to move downward. Under the action of air pressure and spring 907, the bottom end of the anti-counterfeiting inkjet pen 5 and the crimping roller 906 can always fit on the top outer wall of the mica tape wrapped around the outside of the conveying electromagnetic wire, and cooperate with the traction movement of the electromagnetic wire to ensure the accurate drawing of the anti-counterfeiting line on the mica tape wrapped around the electromagnetic wire. Through the overlapping rate detection electric control box 7 and the intelligent camera 6, the anti-counterfeiting line on the mica tape can be monitored and photographed in real time. During the anti-counterfeiting line drawing process, when the anti-counterfeiting inkjet pen 5 passes through the overlapping part of the mica tape, specific ripples will appear on the anti-counterfeiting line. The anti-counterfeiting line analysis module 75 analyzes the waveform of the photographed anti-counterfeiting line, and the anti-counterfeiting line analysis module 75 analyzes the waveform of the photographed anti-counterfeiting line. The waveform analysis detects the overlap rate of the mica tape wrapped around the electromagnetic wire. The detection and analysis of the overlap rate of the mica tape wrapped around the electromagnetic wire can be carried out continuously, which improves the detection efficiency of the overlap rate. After analysis, the overlap rate deviation is found and an unqualified alarm is issued through the alarm 76. Feedback control is used to shut down the electromagnetic wire traction mechanism 2 and the electromagnetic wire wrapping mechanism 3 of the wrapping machine, which is convenient for production personnel to eliminate quality defects of the mica tape wrapped, which is beneficial to the production of electromagnetic wire. During the wrapping and conveying process of the electromagnetic wire of the above-mentioned electromagnetic wire wrapping machine, the first turbine pump 909 continues to work and inject gas. During the air pressure in the end tube 902 reaches the threshold value of the pressure relief valve 912, the excess air is discharged through the air inlet pipe 1012, the second turbine pump 1011 and the output The air pipe 1013 is input into the air blowing head 1010, and the compressed air is blown out through the air blowing head 1010 to blow away the dust on the electromagnetic wire that is not wrapped with mica tape. The air will drive the second turbine pump 1011 to rotate during the process of passing through the second turbine pump 1011, and will drive the guide wheel 104 and the belt 105 to rotate through the transmission shaft 103. During the rotation of the insertion rod 109 on the belt 105, the guide ring 107 will be driven by the guide frame 108 to move back and forth along the guide rod 106, thereby driving the air blowing head 1010 to move back and forth, so that the air blowing head 1010 can comprehensively blow away the dust on the electromagnetic wire that is not wrapped with mica tape, thereby improving the quality of mica tape wrapping on the electromagnetic wire.
