Description
A control method and system for winding equipment Technical Field
[0001] This application relates to the field of transformer winding technology, and in particular to a control method and system for winding equipment. Background Technology
[0002] A transformer is a device that uses the principle of electromagnetic induction to change alternating current voltage. In electrical equipment and wireless circuits, it is commonly used for voltage step-up / step-down, impedance matching, and safety isolation. In the manufacturing process of a dry-type rectifier transformer for variable frequency speed control, copper strip is typically wound onto a hollow coil frame using a manually operated winding machine. During the winding process, the copper strip is pre-formed into taps at predetermined positions. After winding, an iron core is inserted into the hollow part of the coil frame, completing the manufacturing of the rectifier transformer.
[0003] Regarding the aforementioned technologies, the inventors believe that the following defects exist: Since the secondary winding of the dry-type rectifier transformer for frequency conversion speed regulation has a large number of winding groups and the number of turns in each group is different, the winding process by manual operation is prone to mis-winding. Summary of the Invention
[0004] To address the shortcomings of manual winding processes, which are prone to mis-winding, this application provides a winding equipment control method and system.
[0005] In a first aspect, this application provides a method for controlling a winding device, comprising the following steps:
[0006] Obtain winding information, which includes the planned number of winding turns, the planned number of tap turns, and the planned number of taps;
[0007] Acquire video images of the winding area where the coil frame is located;
[0008] Based on the video image, analyze whether the coil frame is located at a preset position in the winding area;
[0009] If the coil frame is in the preset position, the winding module is controlled to wind the coil frame and the real-time number of winding turns of the coil frame is obtained.
[0010] Tap the wire by combining the real-time number of winding turns and the planned number of tap turns, and count the number of taps in real time;
[0011] When the number of real-time taps is equal to the number of planned taps, determine whether the number of real-time winding turns is equal to the number of planned winding turns;
[0012] If the real-time winding turn count is equal to the planned winding turn count, then winding is stopped and a winding completion notification is issued.
[0013] By adopting the above technical solution, video images of the winding area where the coil frame is located are collected and analyzed to determine whether the coil frame is in the preset position. Determining the position of the coil frame before winding reduces the possibility of mis-turns during subsequent winding. The winding information of the current coil frame to be wound is obtained, and the timing of tapping is controlled based on this information. Winding stops when the real-time number of taps equals the planned number of taps and the real-time number of winding turns equals the planned number of winding turns. At this point, the winding process meets the planned winding standard, and a winding completion reminder can be issued. Compared to manual winding, automatically completing the winding by reading winding information is less prone to mis-turns.
[0014] Optionally, the step of analyzing whether the coil frame is located at a preset position in the winding area based on the video image includes the following steps:
[0015] The video image is preprocessed to obtain a preprocessed image;
[0016] Identify the first and second flag positions preset in the winding area in the preprocessed image. When the coil frame is in a preset position in the winding area, one end of the coil frame is located between the first and second flag positions.
[0017] Determine whether the first flag bit has been detected;
[0018] If the first flag bit is not detected, then determine whether the second flag bit is detected;
[0019] If the second flag is detected, the coil frame is determined to be in the preset position.
[0020] By adopting the above technical solution, the preprocessing of the video image after acquisition is beneficial to the subsequent recognition of the flag position. Only when one end of the coil frame is between the first flag position and the second flag position is the coil frame determined to be in the preset position. When the coil frame is between the first flag position and the second flag position, the coil frame will block the first flag position but will not block the second flag position. Therefore, by performing flag position recognition on the video image, when the second flag position is recognized but the first flag position is not recognized, it is determined that the coil frame is in the preset position.
[0021] Optionally, after the control winding module winds the coil bobbin and obtains the real-time number of turns of the coil bobbin, the following steps are further included:
[0022] The control laser module emits a tap calibration laser, which is located outside the coil frame and parallel to the central axis of the coil frame.
[0023] By adopting the above technical solution, the emitted tap calibration laser can be used for subsequent tap position alignment.
[0024] Optionally, the step of combining the real-time winding turns and the planned tap turns to perform tapping and counting the real-time tap count includes the following steps:
[0025] Determine whether the planned number of tap turns has been reached based on the real-time number of winding turns.
[0026] If the planned number of tap turns is reached, the winding is paused, and the tap position is adjusted based on the tap calibration laser.
[0027] After adjusting the tap position, tap the device.
[0028] After the tapping is completed, continue winding and count the number of taps in real time.
[0029] By adopting the above technical solution, when the real-time winding turns reach the planned tap turns, a tapping operation is required. At this time, winding needs to be paused first, and the tap position is finely adjusted according to the tap calibration laser. After the tap position is adjusted to the tap calibration laser position, tapping can be performed, and the real-time tap count is counted. After the tapping is completed, the winding operation continues until the next planned tap turns are reached.
[0030] Optionally, before the control winding module winds the coil bobbin and obtains the real-time number of turns of the coil bobbin, the following steps are included:
[0031] The copper strip to be wound is pulled and connected to the coil frame;
[0032] The constant tension of the copper strip to be wound is controlled within a preset tension range.
[0033] By adopting the above technical solution, the copper strip to be wound is first connected to the coil frame, and the tension of the copper strip to be wound is kept stable. This is beneficial for the coil to be neatly wound on the coil frame during the winding process, and avoids the situation of loose winding or breakage.
[0034] Secondly, this application also provides a winding equipment control system, characterized in that the system includes:
[0035] The information acquisition module is used to acquire winding information, which includes the planned number of winding turns, the planned number of tap turns, and the planned number of taps.
[0036] The image acquisition module is used to acquire video images of the winding area where the coil frame is located;
[0037] A position analysis module, connected to the image acquisition module, is used to determine whether the coil frame is located at a preset position in the winding area based on the video image;
[0038] The winding module is used to wind the copper strip to be wound onto the coil frame and calculate and obtain the real-time number of winding turns of the coil frame.
[0039] A tapping module, connected to the winding module and the information acquisition module, is used to tap during the winding process and count the number of taps in real time.
[0040] The control module is connected to the information acquisition module, the position analysis module, the winding module, and the tap module;
[0041] When the position analysis module determines that the coil frame is in the preset position, the control module controls the winding module to wind the coil.
[0042] When the control module determines that the real-time number of taps is equal to the number of taps, the control module further determines whether the real-time number of winding turns is equal to the planned number of winding turns.
[0043] If the real-time winding turn count is equal to the planned winding turn count, the control module controls the winding module to stop winding and issues a winding completion reminder.
[0044] By adopting the above technical solution, the image acquisition module acquires video images of the winding area where the coil frame is located, and the position analysis module analyzes and determines whether the coil frame is in the preset position. Determining the position of the coil frame before winding reduces the possibility of mis-turns during subsequent winding. The information acquisition module obtains the winding information that the current coil frame needs to be wound. The tapping module controls the tapping timing based on the winding information, and when the real-time tapping number equals the planned tapping number and the real-time winding turns equals the planned winding turns, the control module controls the winding module to stop winding. At this point, the winding process has met the planned winding standard, and a winding completion reminder can be issued. Compared to manual winding, automatically completing winding by reading winding information is less likely to result in mis-turns.
[0045] Optionally, the location analysis module includes:
[0046] A preprocessing unit, connected to the image acquisition module, is used to acquire the video image acquired by the image acquisition module and preprocess the video image to obtain a preprocessed image;
[0047] The flag identification unit, together with the preprocessing unit, is used to identify the first flag and the second flag preset in the winding area of the preprocessed image;
[0048] The judgment unit, connected to the flag identification unit, is used to determine that the coil frame is in the preset position when the flag identification unit identifies the second flag but does not identify the first flag.
[0049] By adopting the above technical solution, the preprocessing unit preprocesses the video image after acquiring it, which is beneficial for the subsequent recognition of the flag position. Only when one end of the coil frame is between the first flag position and the second flag position is the coil frame determined to be in the preset position. When the coil frame is between the first flag position and the second flag position, the coil frame will block the first flag position but will not block the second flag position. Therefore, the flag position recognition unit can perform flag position recognition on the video image. When the flag position recognition unit recognizes the second flag position but does not recognize the first flag position, the judgment unit outputs the judgment result and determines that the coil frame is in the preset position.
[0050] Optionally, the system further includes:
[0051] A laser module is used to emit a tap calibration laser, which is located outside the coil frame and parallel to the central axis of the coil frame.
[0052] By adopting the above technical solution, the tap calibration laser emitted by the laser module can be used for subsequent tap position alignment.
[0053] Optionally, the tap module includes:
[0054] A tapping unit, connected to the winding module, is used to adjust the tap position according to the tap calibration laser and perform tapping when the real-time winding turns reach the planned tap turns.
[0055] The statistics unit, connected to the tapping unit, is used to count the number of taps in real time.
[0056] By adopting the above technical solution, when the real-time winding turns reach the planned tap turns, the tapping operation is performed through the tapping unit. At this time, the winding needs to be paused first, and the tap position is finely adjusted according to the tap calibration laser. After the tap position is adjusted to the tap calibration laser position, the tapping can be performed. The real-time tapping count is counted through the statistics unit. After the tapping is completed, the winding operation continues until the next planned tap turns are reached.
[0057] Optionally, the system further includes:
[0058] The tension holding module is used to pull the copper strip to be wound to connect with the coil frame and control the constant tension of the copper strip to be wound within a preset tension range.
[0059] By adopting the above technical solution, the copper strip to be wound is first connected to the coil frame through the tension holding module, and the tension of the copper strip to be wound is kept stable. This is beneficial to ensure that the coil is neatly wound on the coil frame during the winding process, and to avoid the situation of loose winding or breakage.
[0060] In summary, this application includes at least one of the following beneficial technical effects:
[0061] 1. By analyzing video images of the winding area where the coil frame is located, it is determined whether the coil frame is in the preset position. Determining the position of the coil frame before winding reduces the possibility of mis-turns during subsequent winding. The winding information for the current coil frame needs to be obtained, and the timing of tapping is controlled based on this information. Winding stops when the real-time number of taps equals the planned number of taps and the real-time number of winding turns equals the planned number of winding turns. At this point, the winding process meets the planned winding standards, and a winding completion reminder can be issued. Compared to manual winding, automatically completing the winding by reading winding information is less prone to mis-turns.
[0062] 2. Maintaining a stable tension in the copper strip to be wound helps the coil to be neatly wound on the coil frame during the winding process, and avoids loosening or breakage of the winding. Attached Figure Description

[0068] Figure 6 is a schematic diagram of the steps of one embodiment of the winding device control method of this application. Detailed Implementation
[0069] The present application will be further described in detail below with reference to Figures 1 to 6.
[0070] This application discloses a winding equipment control system.
[0071] Referring to Figure 1, the winding equipment control system includes an information acquisition module, an image acquisition module, a position analysis module, a winding module, a tapping module, and a control module. The information acquisition module is connected to the control module and also to a pre-set backend server. Administrators can pre-store the winding information for coil bobbin adaptation in the backend server. Before winding, the information acquisition module retrieves the winding information from the backend server and transmits it to the control module. The winding information includes the planned number of winding turns, the planned number of taps, and the planned number of taps. There are usually multiple planned number of taps; the planned number of taps indicates when a tapping operation is required when the actual number of winding turns reaches the planned number of taps.
[0072] The coil bobbin is placed onto the winding roller in the winding area manually or by a robotic arm, with the winding roller positioned within the hollow portion of the coil bobbin. The optimal winding positions on the winding roller are marked with a first and a second marker as preset positions. These markers can be painted or affixed with stickers, and their different colors facilitate identification. There is a gap between the first and second markers. When the coil bobbin covers the first marker but not the second, it indicates that the coil bobbin is in the optimal preset winding position.
[0073] The image acquisition module can be a high-definition camera, positioned directly above the winding roller in the winding area. It captures real-time video images of the winding roller. Connected to the position analysis module, the image acquisition module transmits the captured video images to the position analysis module. The position analysis module, connected to the control module, incorporates an OpenCV-based image recognition model. This model identifies a first and second flag, determines whether the coil frame is in a preset position, and sends the result to the control module for further processing.
[0074] The winding equipment control system also includes a laser module and a tension maintaining module. The laser module is located next to the winding roller and emits a tap calibration laser parallel to the central axis of the winding roller and the coil frame. This tap calibration laser is used to maintain the alignment of the taps during subsequent tapping by the tapping module. The tension control module is located at the winding module. A support extends from the winding module towards the coil frame, allowing for quick connection between the copper strip to be wound and the coil frame. After connection, the tension controller in the tension control module tightens the copper strip, increasing its tension and maintaining it within a preset range. This stable tension ensures the coil is neatly wound onto the coil frame during winding, preventing loosening or breakage.
[0075] The control module can be an industrial PLC. It also connects to a winding module and a tapping module. The winding module includes a winding machine and a turns counting instrument. Specifically, after receiving the judgment result from the position analysis module, the control module, based on the planned number of turns in the winding information, controls the winding machine to start winding the coil bobbin with the copper strip to be wound. The turns counting instrument is used to count the turns, and this count is transmitted to the control module in real time. Each time the control module receives a new real-time winding turns count, it compares the real-time winding turns count with the planned tapping turns count. When the real-time winding turns count matches any planned tapping turns count, the control module pauses winding and controls the tapping module to pre-form the copper strip to be wound, completing the tapping operation.
[0076] The tapping module includes a tapping unit and a statistics unit. The tapping unit is connected to the winding module. When the real-time winding turn count reaches the planned tap count, the winding module stops winding and adjusts the tap position according to the tap calibration laser. When the tap position is adjusted to the tap calibration laser position, the tapping unit pre-forms the copper strip to be wound to complete the tapping operation. When the tapping unit completes the tapping operation, the preset tap counter in the statistics unit increments by one. The statistics unit is connected to the control module and transmits the real-time tap count to the control module in real time. Finally, when the control module determines that the real-time winding turn count has reached the planned winding turn count and the real-time tap count has reached the planned tap count, the control module will control the winding module to stop winding and play a sound announcement of winding completion through a preset speaker.
[0077] Referring to Figure 2, the position analysis module includes a preprocessing unit, a flag identification unit, and a judgment unit. The preprocessing unit is connected to the image acquisition module. The preprocessing unit acquires the video images acquired by the image acquisition module and performs image preprocessing operations such as noise reduction and sharpening to obtain a preprocessed image. The flag identification unit is connected to the preprocessing unit. The flag identification unit acquires the preprocessed image obtained by the preprocessing unit and identifies the first and second flags in the preprocessed image using an OpenCV-based image recognition model to obtain the recognition result. The judgment unit is connected to the flag identification unit. The judgment unit acquires the recognition result from the flag identification unit and analyzes it. When the recognition result is that the second flag is identified but the first flag is not identified, the coil frame is determined to be in a preset position. If the recognition result is otherwise, the coil frame is determined not to be in the preset position.
[0078] The implementation principle of this embodiment is as follows:
[0079] The image acquisition module captures video images of the winding area where the coil frame is located, and the position analysis module analyzes and determines whether the coil frame is in the preset position. Determining the position of the coil frame before winding reduces the possibility of mis-turns during the subsequent winding process. The information acquisition module obtains the winding information of the current coil frame that needs to be wound. The tapping module controls the timing of tapping based on the winding information, and when the real-time number of taps equals the planned number of taps and the real-time number of winding turns equals the planned number of winding turns, the control module controls the winding module to stop winding. At this point, the winding process has met the planned winding standard, and a winding completion reminder can be issued. Compared to manual winding, automatically completing the winding by reading winding information is less likely to result in mis-turns.
[0080] Secondly, embodiments of this application also disclose a method for controlling a winding device.
[0081] Referring to Figure 3, the control method for the winding equipment specifically includes the following steps:
[0082] S101. Obtain winding information.
[0083] The administrator can pre-store the winding information for the coil bobbin in the backend server, and retrieve the winding information from the backend server before winding. The winding information includes the planned number of turns, the planned number of taps, and the planned number of taps.
[0084] S102. Acquire video images of the winding area where the coil frame is located.
[0085] The system can capture video images using a high-definition camera, and includes a winding roller in the winding area, with the coil frame placed on the winding roller.
[0086] S103. Analyze whether the coil frame is in the preset position of the winding area based on the video image. If the coil frame is in the preset position, proceed to step S104.
[0087] The optimal winding positions on the winding roller are marked with a first marker and a second marker as preset positions. These markers can be painted or affixed with stickers, and their colors are different to facilitate identification. There is a gap between the first and second markers. When the coil bobbin is placed on the winding roller, if it covers the first marker but not the second, it indicates that the coil bobbin is in the optimal preset winding position. If the coil bobbin is not in the preset position, a position offset alarm is emitted via speaker to remind on-site personnel to adjust its position.
[0088] S104. Control the winding module to wind the coil bobbin and obtain the real-time number of winding turns of the coil bobbin.
[0089] Specifically, the real-time number of turns of the coil bobbin is obtained through a turns counting instrument. That is, the turns counting instrument counts the real-time number of turns and sends the real-time number of turns to the current executing entity. The current executing entity can be a computer, tablet, or other intelligent control device.
[0090] It should be noted that, in specific implementation, the coils wound by the winding module onto the coil bobbin include high-voltage coils and low-voltage coils. For both types of coils, the steps to obtain the real-time winding turn count of the coil bobbin are as follows:
[0091] The real-time winding turns include the number of turns of the high-voltage coil and the number of turns of the low-voltage coil;
[0092] If the coil is a high-voltage coil, obtain the winding stop point of the winding module, and obtain the number of coil turns at each winding stop point in real time. Obtain the cutoff time point, and accumulate the number of coil turns at several stop points to obtain the number of high-voltage coil winding turns of the high-voltage coil at the cutoff time point.
[0093] If the coil is a low-voltage coil, obtain the zero point of the winding module, obtain the number of coil turns at each zero point in real time, and set the number of coil turns at each zero point as the number of low-voltage coil winding turns.
[0094] If the coil is a low-voltage coil, it is only necessary to obtain the number of coil turns at each zeroing point. After obtaining the number of coil turns at each zeroing point, the zeroing process is performed. However, if the coil is a high-voltage coil, the number of coil turns at each stopping point needs to be accumulated.
[0095] S105. Perform tapping by combining the real-time winding turns and the planned tapping turns, and count the real-time tapping count.
[0096] There are usually multiple planned tap turns. The planned tap turns represent the number of turns when the actual winding turns reach the planned tap turns. The real-time winding turns are compared with the planned tap turns. When the real-time winding turns are the same as any of the planned tap turns, the winding module will be controlled to pause winding and start the tapping operation, while the real-time tap count is counted.
[0097] S106. When the number of real-time taps equals the number of planned taps, determine whether the number of real-time winding turns is equal to the number of planned winding turns. If the number of real-time winding turns is equal to the number of planned winding turns, then proceed to step S107.
[0098] If the real-time number of winding turns is not equal to the planned number of winding turns, then winding continues.
[0099] S107. Stop winding and provide a winding completion notification.
[0100] The system includes a pre-set speaker that plays a sound notification indicating the completion of the winding process to remind managers to replace the coil frame.
[0101] The implementation principle of one embodiment of this application is as follows:
[0102] By analyzing video images of the winding area where the coil frame is located, it is determined whether the coil frame is in the preset position. Determining the position of the coil frame before winding reduces the possibility of mis-turns during subsequent winding. The winding information for the current coil frame is obtained, and the timing of tapping is controlled based on this information. Winding stops when the real-time number of taps equals the planned number of taps and the real-time number of winding turns equals the planned number of winding turns. At this point, the winding process meets the planned winding standards, and a winding completion reminder can be issued. Compared to manual winding, automatically completing the winding by reading winding information is less prone to mis-turns.
[0103] In one embodiment of this application, referring to FIG4, step S103 specifically includes the following steps:
[0104] S201. Preprocess the video image to obtain a preprocessed image.
[0105] The preprocessing of video images includes operations such as noise reduction and sharpening to obtain preprocessed images.
[0106] S202. Identify the first and second flags preset in the winding area of the preprocessed image.
[0107] Specifically, a first and second flag bits in the preprocessed image are identified using an OpenCV-based image recognition model. When the coil frame is in a preset position within the winding region, one end of the coil frame is located between the first and second flag bits.
[0108] S203. Determine whether the first flag bit has been identified. If the first flag bit has not been identified, proceed to step S204.
[0109] If the first flag is detected, it is determined that the coil frame is not in the preset position.
[0110] S204. Determine whether the second flag bit is detected. If the second flag bit is detected, proceed to step S205.
[0111] If the second flag is not detected, it is determined that the coil frame is not in the preset position.
[0112] S205. Determine that the coil frame is in the preset position.
[0113] The implementation principle of one embodiment of this application is as follows:
[0114] Preprocessing the video image after acquisition is beneficial for subsequent flag identification. The coil frame is only considered to be in the preset position when one end of the coil frame is between the first and second flags. When the coil frame is between the first and second flags, it will block the first flag but not the second flag. Therefore, the coil frame is considered to be in the preset position when the second flag is identified but the first flag is not identified.
[0115] In one embodiment of this application, the following steps are included after step S104:
[0116] Control the laser module to emit tap calibration laser.
[0117] The tap calibration laser is located outside the coil frame and parallel to the central axis of the coil frame. The emitted tap calibration laser can be used for subsequent tap position alignment.
[0118] In one embodiment of this application, referring to FIG5, step S105 specifically includes the following steps:
[0119] S301. Determine whether the planned number of taps has been reached based on the real-time number of winding turns. If the planned number of taps has been reached, proceed to step S302.
[0120] If the planned number of tap turns is not reached, the winding process continues.
[0121] S302. Pause winding and adjust the tap position based on the tap calibration laser.
[0122] The process involves adjusting the tap position according to the tap calibration laser, and tapping when the tap position is adjusted to the tap calibration laser position.
[0123] S303. Adjust the tap position and then tap.
[0124] The tapping operation is completed by pre-forming the copper strip to be wound at the tapping position.
[0125] S304. After the tapping is completed, continue winding and count the number of taps in real time.
[0126] The implementation principle of one embodiment of this application is as follows:
[0127] When the real-time winding turn count reaches the planned tap count, a tapping operation is required. At this time, winding must be paused first, and the tap position must be finely adjusted according to the tap calibration laser. After the tap position is adjusted to the tap calibration laser position, tapping can be performed, and the real-time tap count is counted. After the tapping is completed, winding operation continues until the next planned tap count is reached.
[0128] In one embodiment of this application, referring to FIG6, the following steps are included before step S104:
[0129] S401. The copper strip to be wound is connected to the coil frame.
[0130] Among them, a bracket can be extended from the winding module toward the coil frame, and the copper strip to be wound can be quickly connected to the coil frame by pulling the extended bracket.
[0131] S402. Control the constant tension of the copper strip to be wound within the preset tension range.
[0132] Specifically, the tension of the copper strip to be wound is increased by tightening it with a tension controller, and the tension of the copper strip to be wound is maintained within the tension range preset in the tension controller.
[0133] The implementation principle of one embodiment of this application is as follows:
[0134] First, connect the copper strip to be wound to the coil frame and keep the tension of the copper strip stable. This helps to ensure that the coil is neatly wound on the coil frame during the winding process and avoids loose or broken winding.
[0135] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
