Description

Technical Field

[0002] The coil is the core of the transformer's transformation and distribution of electric energy. The process size of the coil winding process is an important factor affecting the performance and stability of the transformer. Due to the complex process, the coil winding and testing of ultra-high voltage transformers are mainly completed manually. However, manual testing has the following problems:

[0003] 1. Low detection accuracy: Due to human factors and limitations of measuring tools, it is difficult to ensure that the size of each coil manually detected meets the standard requirements, resulting in inconsistent sizes of manufactured coils, affecting the overall performance and stability of the transformer.

[0004] 2. Low detection efficiency: Due to the complex and varied coil sizes, operators are required to repeatedly measure and adjust, which consumes a lot of time and human resources, and has problems such as inconvenient operation and slow measurement speed, which seriously affects production efficiency and delivery cycle.

[0005] 3. Poor stability of finished products: Due to reliance on manual measurement, the coil winding process often needs to be interrupted and tested, resulting in large quality fluctuations and long production cycles. The operator's technical level, working status and other factors will affect the quality and production efficiency of the coil.

When the combination of technical solutions is contradictory or cannot be implemented, it should be deemed that such combination of technical solutions does not exist and is not within the scope of protection required by the present invention.

[0060] The present invention provides a coil detection device 100 .

[0061] Please combine Figure 1 and Figure 2In one embodiment of the present invention, the coil detection device 100 includes a winding machine 1, a detection mechanism 2 and a control system. The winding machine 1 includes a rotating drive member 11 and a mold 12 for installing a sleeve 3. The sleeve 3 is used to wind the coil. The rotating drive member 11 is used to drive the mold 12 to rotate to drive the sleeve 3 on the mold 12 to rotate; the detection mechanism 2 includes a driving component 21 and a laser scanner 22. The driving component 21 drives the laser scanner 22 to move in the horizontal direction and the vertical direction. The laser scanner 22 is used to detect the sleeve size data of the sleeve 3 and the coil size data of the coil; the laser scanner 22 is electrically connected to the control system, and the laser scanner 22 sends the detected size data to the control system. The control system is used to obtain the winding error of the coil according to the sleeve size data and the coil size data, and to issue an alarm when the winding error exceeds the preset error range.

[0062] The technical solution of the present invention drives the mold 12 to rotate the sleeve 3 by rotating the driving part 11, so that the operator can wind the coil outside the sleeve 3 without rotating the sleeve 3, thereby improving the winding efficiency. At the same time, a detection mechanism 2 is set, and the driving component 21 can drive the laser scanner 22 to move to the outside of the sleeve 3, and can be lifted and lowered vertically, so that the sleeve size data of the sleeve 3 and the coil size data of the coil can be detected, and the winding error of the coil can be obtained through the sleeve size data and the coil size data, and the finished product quality of the coil can be judged. When the winding error is large, the winding is stopped and an alarm is issued to prompt the operator to correct it in time. The present invention drives the laser scanner 22 to move through the driving component 21, and drives the sleeve 3 and the coil on the sleeve 3 to rotate through the mold 12, so as to realize accurate detection of the outer periphery of the coil and the dimensions at each height, and no missed detection will occur. The laser scanner 22 has higher accuracy and is not affected by subjective human factors, thereby greatly improving the detection accuracy; the cooperation between the detection mechanism 2 and the winding machine 1 realizes automatic detection without manual detection, and can be automatically adjusted through the control system without manual measurement and adjustment, thereby improving the detection efficiency; the rotating drive member 11 drives the sleeve 3 to rotate, so that the operator does not need to wind the wire by himself, and no manual measurement is required, so that the operator's workload is greatly reduced, the production efficiency is increased, the production cycle is shortened, and the influence of the operator's personal factors on the winding quality is reduced, thereby improving the stability of the finished product.

[0063] In one embodiment, the driving assembly 21 includes a lifting driving member 211 and a telescopic cantilever 212. The lifting driving member 211 is used to drive the telescopic cantilever 212 to rise and fall. The fixed end of the telescopic cantilever 212 is connected to the lifting driving member 211, and the other end is provided with a laser scanner 22. Through the cooperation of the lifting driving member 211 and the telescopic cantilever 212, the laser scanner 22 can move freely in the horizontal direction and the vertical direction, thereby increasing the detection range of the laser scanner 22, and can accurately detect the coil size data at each position of the coil, thereby improving the detection accuracy.

[0064] Furthermore, a grating ruler is provided on both the lifting drive 211 and the telescopic cantilever 212. The grating ruler can provide submicron or even nanometer measurement accuracy, and adjusting the lifting drive 211 and the telescopic cantilever 212 according to the reading of the grating ruler can improve the positioning accuracy of the lifting drive 211 and the telescopic cantilever 212, thereby improving the detection accuracy of the coil.

[0065] In one embodiment, the winding machine 1 further includes an encoder, which is electrically connected to the control system. The encoder is used to send a scanning signal to the control system when the rotating drive member 11 is started, and the control system controls the laser scanner 22 to start after receiving the scanning signal. The start and stop of the laser scanner 22 are linked together with the start and stop of the rotating drive member 11 through the encoder, so that the laser scanner 22 will only perform detection when the mold 12 rotates, and there is no need for frequent manual control of the start and stop of the laser scanner 22, which simplifies the detection process and improves the detection efficiency. At the same time, the laser scanner 22 will not obtain useless data, and the accuracy of the detected sleeve 3 and coil size data is improved.

[0066] Please combine Figures 1 to 3 The present invention further proposes a coil detection method, which is applied to the above-mentioned coil detection device 100. The coil detection method comprises the following steps:

[0067] S100: Obtain the model of the coil, and obtain corresponding coil standard parameters and preset error range from the control system according to the model;

[0068] The coil has an information code. The operator scans the information code of the coil with a barcode scanner to obtain the model of the coil. The model of the coil is input into the control system and matched with various types of coils stored in the control system to obtain the standard parameters of the coil of the corresponding model and the corresponding preset error range.

[0069] S200: installing the sleeve on the mold, and acquiring sleeve size data of the sleeve by using the laser scanner;

[0070] It can be understood that due to the limitation of process and material, the sleeve 3 is not a completely regular cylinder, so the surface of the sleeve 3 is not flat at all places, and the radius of each place of the sleeve 3 is not completely the same, so the sleeve size data of the sleeve 3 is obtained by the laser scanner 22, so as to calculate the coil size data according to the sleeve size data of different areas, thereby improving the detection accuracy of the coil;

[0071] S300: The rotating driving member drives the sleeve to rotate through the mold to wind the coil onto the sleeve;

[0072] The mold 12 is driven by the rotating driving member 11 to drive the sleeve 3 to rotate, so that the operator can wind the coil outside the sleeve 3 without rotating the sleeve 3, thereby improving the winding efficiency;

[0073] S400: Acquire coil size data of the coil by using the laser scanner;

[0074] It should be noted that, because the laser scanner 22 will only rise and fall during the detection process, and will not move horizontally, the operator does not need to stop winding the coil during the detection of the coil. The operator only needs to avoid the area where the laser scanner 22 and the coil are facing, so as not to affect the detection of the laser scanner 22.

[0075] S500: Obtaining a winding error of the coil according to the sleeve size data, the coil standard parameters and the coil size data;

[0076] The actual data of the coil is obtained according to the sleeve size data and the coil size data, and then the actual data of the coil is subtracted from the standard parameters of the coil to obtain the winding error;

[0077] S600: comparing the winding error with the preset error range, if the winding error is within the preset error range, continuing to wind the coil onto the sleeve, if the winding error exceeds the preset error range, stopping the rotating drive component and issuing an alarm, and repairing the coil;

[0078] During the winding process, if the winding error of the coil scanned by the laser scanner 22 exceeds the preset error range, it means that the coil size is unqualified. At this time, the rotation of the rotating drive member 11 is stopped and an alarm is sounded. After hearing the alarm, the operator corrects the coil at the unqualified size. In actual application scenarios, after the correction, the on-site management personnel need to come to the site to check the coil to determine the correction effect;

[0079] S700: Return to step S300 until all the coils are wound.

[0080] When the on-site manager determines that the coil meets the requirements after trimming, the rotary drive member 11 is started to continue the winding operation until all the coils are wound.

[0081] In the technical solution of the present invention, the model of the coil is first obtained, and the standard parameters of the coil of the corresponding model and the corresponding preset error range are obtained according to the model of the coil. Then, the size data of the sleeve 3 is obtained by the laser scanner 22. After the size data of the sleeve 3 is stored, the winding operation is started. While the winding operation is in progress, the laser scanner 22 is started to detect the size data of the coil, and the winding error of the coil is obtained according to the sleeve size data, the coil standard parameters and the coil size data to determine whether the size of the coil meets the requirements. If the winding error of the coil exceeds the preset error range, the size of the coil is determined to be unqualified. At this time, the rotation of the rotating drive member 11 is stopped and an alarm is issued. The operator corrects the unqualified part of the coil. After the correction is completed, the rotating drive member 11 is started again to wind the coil, and the size data of the coil is detected in real time until the coil is completely wound. The present invention drives the laser scanner 22 to move through the driving component 21, and drives the sleeve 3 and the coil on the sleeve 3 to rotate through the mold 12, so as to realize accurate detection of the outer periphery of the coil and the dimensions at each height, and no missed detection will occur. The laser scanner 22 has higher accuracy and is not affected by subjective human factors, which greatly improves the detection accuracy; the cooperation between the detection mechanism 2 and the winding machine 1 realizes automatic detection, without manual detection, and can be automatically adjusted through the control system, without manual measurement and adjustment, thereby improving the detection efficiency; the rotating drive member 11 drives the sleeve 3 to rotate, so that the operator does not need to wind the wire by himself, and no manual measurement is required, so that the operator's workload is greatly reduced, the production efficiency is increased, and the detection is carried out simultaneously during the coil winding process, so that the production cycle is reduced, and the influence of the operator's personal factors on the winding quality is reduced, thereby improving the stability of the finished product.

[0082] See also Figure 4 In one embodiment, the driving assembly includes a lifting driving member and a telescopic cantilever, and a grating ruler is provided on the lifting driving member and the telescopic cantilever;

[0083] The process before step S200 includes:

[0084] S190: driving the laser scanner to move to the top of the sleeve through the lifting drive member and the telescopic cantilever, and making the light emitting point of the laser scanner correspond to the rotation axis of the mold;

[0085] Step S200 includes:

[0086] S210: adjusting the lifting drive member and the telescopic cantilever according to the reading of the grating ruler, so that the laser scanner moves to the outside of the outer periphery of the sleeve;

[0087] By adjusting the lifting drive member 211 and the telescopic cantilever 212 according to the reading of the grating ruler, the positioning accuracy of the lifting drive member 211 and the telescopic cantilever 212 can be improved, thereby improving the detection accuracy of the sleeve 3;

[0088] S220: The rotating driving component drives the sleeve to rotate through the mold to obtain the sleeve size data through the laser scanner.

[0089] During the rotation of the sleeve 3, the laser scanner 22 does not move, so that the dimensions of each location of the sleeve 3 along its periphery can be detected by the laser scanner 22, thereby improving the integrity of the sleeve dimension data and improving the accuracy of the subsequent calculation of the coil dimension data;

[0090] Furthermore, after step S220, the following steps are further included:

[0091] S230: adjusting the lifting drive member according to the reading of the grating ruler to adjust the height of the laser scanner;

[0092] The height of the laser scanner 22 is adjusted by the lifting drive 211, so that the laser scanner 22 can be moved gradually from bottom to top or from top to bottom;

[0093] S240: The rotary driving member drives the sleeve to rotate through the mold, so as to obtain the sleeve size data through the laser scanner;

[0094] Each time the laser scanner 22 moves to a certain height, the rotary drive member 11 drives the sleeve 3 to rotate one circle through the mold 12, so that the laser scanner 22 can obtain the size of the sleeve 3 at any angle at this height, thereby improving the detection accuracy;

[0095] Specifically, the outer wall of the sleeve 3 is provided with struts at intervals, and the struts are used to support the coil wound to the outside of the sleeve 3. The dimensional data of the sleeve 3 include the outer diameter, verticality, bottom end face inclination, circumference, and equal spacing of the struts.

[0096] S250: Return to execute step S230 at least three times, and send the sleeve size data at each height to the control system.

[0097] It is understandable that, affected by the manufacturing process and materials, the sleeve 3 will not be a regular cylinder, that is, the radius of the sleeve 3 at different locations along the vertical direction will be different. Therefore, the height of the laser scanner 22 is adjusted to obtain the dimensional data of the sleeve 3 at various angles at various heights, thereby improving the accuracy of subsequent calculations of the actual size of the coil, thereby improving the detection accuracy. It should be noted that the number of times step S230 is returned to be executed depends on the accuracy requirements of the coil. If the dimensional quality requirements of the coil are extremely high, the number of executions of step S230 can be increased to improve the detection accuracy of the coil. If the requirements are lower, the number of executions of step S230 can be reduced to improve the detection efficiency.

[0098] Furthermore, the sleeve 3 also has standard parameters of the sleeve 3. If during the size detection process of the sleeve 3 it is found that the error between the size data of the sleeve 3 and the standard parameters of the sleeve 3 exceeds a preset value, generally ±1 mm, an alarm is issued and the abnormal point is marked, and the operator repairs the abnormal point.

[0099] See also Figure 5 In one embodiment, step S400 includes:

[0100] S410: adjusting the lifting drive member and the telescopic cantilever according to the reading of the grating ruler, so that the laser scanner moves to the outside of the outer periphery of the sleeve;

[0101] By adjusting the lifting drive member 211 and the telescopic cantilever 212 according to the reading of the grating ruler, the positioning accuracy of the lifting drive member 211 and the telescopic cantilever 212 can be improved, thereby improving the detection accuracy of the coil;

[0102] S420: driving the laser scanner to move up and down by the lifting driving member, and detecting the initial coil size data of the coil by the laser scanner, wherein the laser scanner can rise from the bottom of the sleeve to the top of the sleeve, or descend from the top of the sleeve to the bottom of the sleeve;

[0103] S430: Return to execute step S420 multiple times, and calculate the average of the initial coil size data obtained by multiple detections to obtain the coil size data.

[0104] The laser scanner 22 moves to the outside of the sleeve and faces the coil. If the initial state is at the top position of the sleeve, the laser scanner 22 moves from top to bottom and detects the size parameters of the coil during the movement. It can be understood that the laser scanner 22 is used to obtain the distance between the coil and the distance before the sleeve obtained in the previous step, so as to obtain the width of the coil, that is, the diameter of the coil, so as to obtain the initial coil size data of the coil. After the laser scanner 22 moves to the bottom, it moves from bottom to top and detects the initial coil size data of the coil again. The detection is repeated many times, and the average is calculated to obtain accurate coil size data and improve the detection accuracy.

[0105] In a specific embodiment, the coil size data includes the outer diameter, inner diameter, radial size, number of coil segments, number of coil turns, axial protrusion, line segment unevenness, strut equal division spacing, strut verticality and other data of the coil.

[0106] In one embodiment, after step S190, the method further includes:

[0107] S191: adjusting the lifting drive member and the telescopic cantilever according to the reading of the grating ruler, so that the laser scanner moves to the outside of the periphery of the mold;

[0108] By adjusting the lifting drive member 211 and the telescopic cantilever 212 according to the reading of the grating ruler, the positioning accuracy of the lifting drive member 211 and the telescopic cantilever 212 can be improved, thereby improving the detection accuracy of the mold 12;

[0109] S192: The rotating driving member drives the mold to rotate through the mold, so as to obtain mold size data of the mold through the laser scanner;

[0110] During the rotation of the mold 12, the laser scanner does not move, so that the dimensions of each location of the mold 12 along its periphery can be detected by the laser scanner, thereby improving the integrity of the mold dimension data and the accuracy of the subsequent calculation of the coil dimension data;

[0111] S193: adjusting the lifting drive member according to the reading of the grating ruler to adjust the height of the laser scanner;

[0112] The height of the laser scanner 22 is adjusted by the lifting drive 211, so that the laser scanner 22 can be moved gradually from bottom to top or from top to bottom;

[0113] S194: The rotary driving member drives the mold to rotate, so as to obtain the mold size data through the laser scanner;

[0114] Each time the laser scanner 22 moves to a certain height, the rotary drive member 11 drives the mold 12 to rotate one circle, so that the laser scanner 22 can obtain the dimensions of the mold 12 at any angle at this height, thereby improving the detection accuracy;

[0115] S195: Return to execute step S193 at least three times, and send the mold size data at each height to the control system;

[0116] The mold dimensions at each height are recorded to take the error of the mold 12 into account within the error range, thereby improving the accuracy of subsequent calculations of the actual dimensions of the coil, thereby improving the detection accuracy;

[0117] Step S500 includes:

[0118] S510: Obtaining the winding error of the coil according to the mold size data, the sleeve size data, the coil standard parameters and the coil size data.

[0119] The mold size data is taken into consideration when calculating the winding error, which eliminates the influence of the sleeve and the mold 12 on the coil size to the greatest extent, thereby improving the accuracy of coil size detection and improving the detection efficiency of the coil.

[0120] In one embodiment, after step S700, the method further includes:

[0121] S710: Generate a coil model according to the coil size data and the sleeve size data;

[0122] S720: The coil model is transmitted to the control system and stored.

[0123] After the coil and sleeve are wound, a coil model is generated based on the coil size data and sleeve size data of the component and stored in the control system for subsequent production quality inspection and reference during process optimization, providing benchmark data for subsequent operations.
