Description

Technical Field

[0001] This invention relates to the field of thermal sensor design technology, and in particular to a method, system, device and medium for producing thermal sensors using ultrafine wires. Background Technology

[0002] In recent years, driven by the localization process of my country's semiconductor industry, my country's semiconductor discrete device market has occupied an increasingly important position in the world, and the semiconductor industry is full of opportunities and challenges.

[0003] In the semiconductor industry, the sensor production process is particularly important. A good production process can effectively improve the yield of sensors. Sensor production systems (such as winding devices) are key equipment in the manufacturing of electronic components. However, with the increasing demand for miniaturization and high precision, traditional winding devices have obvious shortcomings in terms of ultra-fine wire winding, complex winding patterns, efficiency and consistency, making it difficult to meet the requirements of modern manufacturing.

[0004] With the development of industrial automation, traditional winding devices can no longer meet the needs of modern production. For example, existing technologies struggle to guarantee the speed at which ultrafine wires are wound onto capillaries, leading to uneven winding on the capillary and affecting yield. Furthermore, existing technologies also struggle to ensure tension control of ultrafine wires during automatic winding; insufficient tension control precision can easily cause wire breakage or misalignment. Additionally, existing technologies provide overly coarse inspection of the wound capillary after winding. Therefore, it is necessary to improve the winding method of thermal sensors to meet the demands of modern industrial production in terms of wire winding and complex winding patterns. Summary of the Invention

[0005] Therefore, the technical problem to be solved by the present invention is to overcome the problem that the existing capillary winding method is difficult to meet the needs of modern industrial production in terms of ultra-fine wire winding and complex winding patterns, thus affecting the yield rate.

[0006] To solve the above-mentioned technical problems, the present invention provides a method for producing a thermal sensor using ultrafine wires, comprising:

[0007] Step S1: Control the capillary tube to rotate by the third drive motor, so that the wire from the coil frame passes through the wire needle and is wound into the capillary tube to be wound. Control the second drive motor connected to the wire needle to rotate and adjust the position of the wire needle to guide the wire to move towards the capillary tube to be wound.

[0008] Step S2: During the winding of the wire into the capillary tube, the tension of the wire is acquired by the tension sensor set in front of the wire needle. Based on the acquired wire tension, the first drive motor connected to the coil frame is controlled to adjust the rotation speed to change the rotation speed of the coil frame, thereby keeping the wire tension within the preset tension range.

[0009] Step S3: After the capillary winding is completed, obtain an image of the capillary wire winding. Based on the wire winding image, determine whether there is a problem with the winding. If there is a problem, mark the location of the problem; if there is no problem, the detection is complete.

[0010] In one embodiment of the present invention, the second drive motor and the third drive motor operate synchronously to match the offset speed of the guide needle controlled by the second drive motor with the rotation speed of the capillary tube controlled by the third drive motor, as shown in the formula:

[0011] ;

[0012] in, The linear velocity of the guide needle's left and right deflection. The speed of capillary rotation. The spacing between the wires wound on the capillary tube.

[0013] In one embodiment of the present invention, the method of adjusting the rotation speed of the first drive motor connected to the coil frame according to the acquired wire tension in step S2 to change the rotation speed of the coil frame, thereby keeping the wire tension within a preset tension range, includes:

[0014] Set the preset tension range for the conductor;

[0015] During the winding process, the tension of the wire detected by the tension sensor is acquired;

[0016] When the conductor tension is within the preset tension range, no adjustment is made to the conductor tension;

[0017] When the conductor tension exceeds the preset tension range, the rotation speed of the first drive motor connected to the coil frame is increased, thereby reducing the conductor tension to prevent the conductor from breaking due to excessive tension.

[0018] When the conductor tension is less than the preset tension range, the rotation speed of the first drive motor connected to the coil frame is slowed down, thereby increasing the conductor tension.

[0019] In one embodiment of the present invention, when the tension of the conductor is greater than or less than a preset tension range, the rotation speed of the first drive motor connected to the coil frame is increased or decreased, specifically as follows:

[0020] A quadratic function is constructed to control the tension; the formula is as follows: ,in, For the current tension; This is the actual feedback value from the tension sensor; The ideal feedback signal value corresponds to the target tension; Preset tension range; For sensitivity parameters and ;

[0021] During the winding process, if the conductor tension is outside the preset tension range, the deviation can be calculated using the formula... An adjustment signal is generated by the output signal of the first drive motor, and is expressed through the formula. This allows for adjusting the speed of the first drive motor, thereby changing the tension of the conductor and enabling dynamic wire feeding. This is the proportional gain coefficient, used to determine the direct response strength to tension deviation; The rate of change of tension deviation over time is used to reflect the trend and speed of tension changes in order to predict future deviation dynamics. This is the differential gain coefficient, used to reflect the response strength to the rate of change of tension deviation.

[0022] In one embodiment of the present invention, the wire diameter ranges from 0.01mm to 0.05mm.

[0023] In one embodiment of the present invention, the method for identifying the location of the problem in step S3 includes:

[0024] The acquired wire winding image is processed into a grayscale image.

[0025] Smooth the grayscale image using Gaussian filtering;

[0026] Based on the image after Gaussian filtering, the fixed winding area on the capillary is extracted as the region of interest and binarized to highlight the edge of the wire.

[0027] The edge of the wire is extracted by the Canny operator, and the distribution of adjacent windings in the segmented coil on the capillary and the adjacent windings in each segment of the coil are judged by the straight line detection operator to detect whether the winding is uniform and whether there are gaps.

[0028] Calculate the spacing between the segmented coils on the capillary tube and the spacing between adjacent windings within each segment. If the spacing is less than the corresponding preset value, overlapping may occur; if the spacing is greater than the corresponding preset value, misalignment or loose winding may occur.

[0029] When a defect is detected in the winding, the coordinates of the defect area are recorded and displayed.

[0030] In one embodiment of the present invention, the method for extracting a fixed winding region on a capillary as a region of interest based on a Gaussian-filtered image includes:

[0031] Extract the outline of the wound capillary;

[0032] Based on the coordinates corresponding to the two contours of the capillary , ,according to , , , Fitting to obtain the coordinates of the capillary midline and the equation of the midline ,in, , , To take the absolute value;

[0033] Set the starting point of the winding Single coil length Then the starting point of the winding will be... and single-segment coil length Substituting the midline equation, the recognition region is obtained as follows: , And this identified region is taken as the region of interest, where, To adjust the coefficient, , Where is the capillary radius. The diameter of the conductor;

[0034] When the capillary has segmented coils, the method for dividing the recognition region of the first segmented coil is the same as the method for obtaining the region of interest with a single segmented coil. The recognition region corresponding to each subsequent segmented coil is represented as follows: , And the recognition area corresponding to each subsequent coil segment is taken as the region of interest, where, , , The length of each coil segment, The spacing width between adjacent coils. This indicates that the current coil region is the first one wound on the capillary tube. Segment coil.

[0035] To address the aforementioned technical problems, this invention provides a thermal sensor manufacturing system using ultrafine wires, comprising:

[0036] Control module: Used to control the capillary tube to rotate via the third drive motor, so that the wire from the coil frame passes through the wire needle and winds the wire into the capillary tube to be wound; and to control the second drive motor connected to the wire needle to rotate so that the wire needle is adjusted in position to guide the wire to move towards the capillary tube to be wound.

[0037] Adjustment module: used to acquire the tension of the wire collected by the tension sensor set in front of the wire needle during the winding process of the wire into the capillary tube, and control the first drive motor connected to the coil frame to adjust the rotation speed according to the acquired wire tension, so as to change the rotation speed of the coil frame and thus keep the wire tension within the preset tension range.

[0038] Judgment module: After the capillary winding is completed, it acquires an image of the capillary wire winding and determines whether there is a problem with the winding based on the image. If there is a problem, the location of the problem is marked; if there is no problem, the detection is completed.

[0039] To solve the above-mentioned technical problems, the present invention provides a thermal sensor, which is manufactured using the above-described method for producing thermal sensors with ultra-fine wires.

[0040] To address the aforementioned technical problems, the present invention provides an electronic device, including a memory, a processor, and a computer program stored in the memory and executable on the processor. When the processor executes the computer program, it implements the steps of the above-described method for producing a thermal sensor using ultrafine wires.

[0041] To address the aforementioned technical problems, the present invention provides a computer-readable storage medium storing a computer program thereon, which, when executed by a processor, implements the steps of the above-described method for producing a thermal sensor using ultrafine wires.

[0042] The technical solution of the present invention has the following advantages compared with the prior art:

[0043] The thermal sensor production method using ultrafine wires described in this invention can control the rotation speed of the wire coil wound on the capillary tube in real time through the feedback signal of the tension sensor. If the wire tension is not within the preset tension range, the rotation speed of the coil frame can be changed by increasing or decreasing the speed of the first drive motor, thereby changing the wire tension for dynamic wire feeding. Furthermore, this invention enables the winding of ultrafine wires with a minimum diameter of 0.01mm-0.05mm through high-precision tension control, meeting the current industrial demand for fine winding.

[0044] This invention can detect whether there are quality problems such as overlap or misalignment in the winding of the capillary after the winding is completed, and mark the positions of overlap and misalignment. In addition, during the identification process, this invention extracts each section of the coil on the same capillary as the region of interest to maximize the detection of overlap and misalignment.

[0045] To make the content of this invention easier to understand, the invention will be further described in detail below with reference to specific embodiments and accompanying drawings.

[0046] Figure 1 This is a flowchart of the method for producing a thermal sensor using ultra-fine wires in an embodiment of the present invention; Figure 2 This is a schematic diagram of the thermal sensor manufacturing process in an embodiment of the present invention. Detailed Implementation

[0047] The present invention will be further described below with reference to the accompanying drawings and specific embodiments, so that those skilled in the art can better understand and implement the present invention. However, the embodiments described are not intended to limit the present invention. Example 1

[0048] Reference Figure 1 and Figure 2 As shown, the present invention relates to a method for manufacturing a thermal sensor using ultrafine wires, comprising:

[0049] Step S1: Control the capillary tube to rotate by the third drive motor, so that the wire from the coil frame passes through the wire needle and is wound into the capillary tube to be wound. Control the second drive motor connected to the wire needle to rotate and adjust the position of the wire needle to guide the wire to move towards the capillary tube to be wound.

[0050] Step S2: During the winding of the wire into the capillary tube, the tension of the wire is acquired by the tension sensor set in front of the wire needle. Based on the acquired wire tension, the first drive motor connected to the coil frame is controlled to adjust the rotation speed to change the rotation speed of the coil frame, thereby keeping the wire tension within the preset tension range.

[0051] Step S3: After the capillary winding is completed, obtain an image of the capillary wire winding. Based on the image, determine whether there is a problem with the winding. If there is a problem, mark the location of the problem. If there is no problem, the detection is completed (equivalent to the end of the entire capillary winding process).

[0052] The following is a detailed description of this embodiment:

[0053] In this embodiment, the second and third drive motors operate synchronously, ensuring that the offset speed of the lead needle controlled by the second drive motor and the rotation speed of the capillary tube controlled by the third drive motor are matched (ensuring that the offset speed of the lead needle and the rotation speed of the coil frame operate synchronously). The formula is as follows:

[0054]

[0055] in, The linear velocity of the guide needle's left and right deflection. The speed of capillary rotation. The spacing between the wires wound on the capillary tube.

[0056] Furthermore, the method in step S2 of adjusting the rotation speed of the first drive motor connected to the coil frame according to the obtained wire tension to change the rotation speed of the coil frame, thereby keeping the wire tension within the preset tension range, includes:

[0057] Set the preset tension range for the conductor;

[0058] During the winding process, the current tension of the conductor detected by the tension sensor is acquired;

[0059] When the conductor tension is within the preset tension range, no adjustment is made to the conductor tension;

[0060] When the conductor tension exceeds the preset tension range, the rotation speed of the first drive motor connected to the coil frame is increased, thereby reducing the conductor tension to prevent the conductor from breaking due to excessive tension.

[0061] When the conductor tension is less than the preset tension range, the rotation speed of the first drive motor connected to the coil frame is slowed down, thereby increasing the wire feeding tension and preventing the wound coil from shifting due to loosening.

[0062] It should be noted that in this embodiment, the first drive motor only adjusts its rotation speed when the wire tension is too high or too low. Under normal circumstances, the first drive motor only provides a normal supply speed.

[0063] Specifically, when the conductor tension is greater than or less than a preset tension range, the rotation speed of the first drive motor connected to the coil frame is increased or decreased accordingly.

[0064] A quadratic function is constructed to control the tension; the formula is as follows: ,in, The tension currently being monitored in real time; This is the actual feedback value from the tension sensor; The ideal feedback signal value corresponds to the target tension; The preset tension range (in practical applications, only one value is needed, that is, the tension value corresponding to the tension extreme point); For sensitivity parameters and ;

[0065] During the winding process, if the conductor tension is outside the preset tension range, the deviation can be calculated using the formula... An adjustment signal is generated by the output signal of the first drive motor, and is expressed through the formula. This allows for adjusting the speed of the first drive motor, thereby changing the tension and enabling dynamic wire feeding. The tension currently being monitored in real time. To preset the tension range, This is the proportional gain coefficient, used to determine the direct response strength to tension deviation; The rate of change of tension deviation over time is used to reflect the trend and speed of tension changes in order to predict future deviation dynamics. The differential gain coefficient represents the response strength of the control system to the rate of change of tension deviation. The larger the value, the stronger the response to rapidly changing deviations, thus mitigating tension fluctuations.

[0066] Specifically, the proportion part ( The first drive motor is adjusted directly based on the magnitude of the tension deviation, providing a fast response; the differential part ( Based on the changing trend of the deviation, predictive adjustments are made to suppress oscillations and fluctuations. Through the closed-loop feedback between these two parts, the control of the first drive motor can dynamically adjust the speed of the coil frame, keeping the tension within the target range while avoiding over-adjustment and delay.

[0067] It is worth mentioning that the wire diameter in this embodiment ranges from 0.01mm to 0.05mm, while traditional methods typically use wire diameters of 0.2mm or more for thermal sensors. The reason this embodiment can control the wire diameter within the 0.01mm-0.05mm range is based on the aforementioned quadratic function. To achieve tension control, when the conductor tension is outside the preset tension range, the formula is used. The speed of the first drive motor can be increased or decreased, thereby changing the tension and enabling dynamic wire feeding.

[0068] Specifically, the method for identifying the location of the problem in step S3 includes:

[0069] S31: Perform grayscale processing on the acquired wire winding image to obtain a grayscale image;

[0070] S32: Smooth the grayscale image using Gaussian filtering;

[0071] S33: Based on the image after Gaussian filtering, the fixed winding area on the capillary is extracted as the region of interest and binarized to highlight the edge of the wire.

[0072] S34: The edge of the wire is extracted by the Canny operator, and the distribution of adjacent windings in the segmented coils on the capillary and the adjacent windings in each segment of the coil are judged by the straight line detection operator to detect whether the windings are uniform and whether there are gaps.

[0073] S35: Calculate the spacing between the segmented coils on the capillary and the spacing between adjacent windings within each segment. If the spacing is less than the corresponding preset value (first preset value and second preset value), overlapping may occur; if the spacing is greater than the corresponding preset value (first preset value and second preset value), misalignment or loose winding may occur. A segmented coil can be understood as follows: for example, if the capillary has two coil segments, with a 3mm gap between them, and each coil segment has 20 windings, then these two coil segments form the segmented coil of the capillary. Adjacent windings within each segment can be understood as follows: for example, if the same coil segment has 20 windings, then adjacent windings within these 20 windings are the adjacent windings of each coil segment.

[0074] S36: When a defect is detected in the winding, record the coordinates of the defect area and display them (the specific display can be made on the monitor).

[0075] Furthermore, after the capillary winding in this embodiment is completed, 90 degrees is taken as one rotation cycle of the capillary, and the winding image of the capillary wire is captured in each rotation cycle, which serves as the basis for winding quality inspection.

[0076] It should be noted that the winding method on the capillary in this embodiment is not unique. When there are segmented coils in the capillary, this embodiment needs to extract the region of interest (ROI) for each segment of the coil for analysis to further reduce the amount of defect detection data.

[0077] Furthermore, methods for extracting the fixed winding region on the capillary as the region of interest based on the image after preprocessing (i.e., after Gaussian filtering) include:

[0078] (1) Extract the outline of the wound capillary;

[0079] (2) Based on the coordinates corresponding to the two contours of the capillary (equivalent to the upper and lower sides of the capillary) , ,according to , , , Fitting to obtain the coordinates of the capillary midline and the equation of the midline ,in, , , To take the absolute value;

[0080] (3) Set the starting point of the winding Single coil length Then the starting point of the winding will be... and single-segment coil length Substituting the above midline equation, the identification region is obtained as follows: , And this identified region is taken as the region of interest, where, To adjust the coefficient, , Where is the capillary radius. The diameter of the conductor;

[0081] (4) When the winding is multi-segmented (i.e., the capillary needs to be wound with segmented coils), the method for dividing the identification region of the first segment of the multi-segment coil is the same as the method for obtaining the region of interest of a single-segment coil. The identification region corresponding to each subsequent segment is represented as follows: , And the recognition area corresponding to each subsequent coil segment is taken as the region of interest, where, , , The length of each coil segment, The spacing width between each adjacent coil segment, This indicates that the current coil region is the nth segment of the coil wound on the capillary tube.

[0082] In this embodiment, the opening of the lead needle is less than 0.2mm, enabling precise guidance of extremely fine wires to be wound along a designated path without deviating from the winding trajectory. A high-precision stepper motor combined with a guide rail system allows for coil winding spacing accurate to the micrometer level. Example 2

[0083] This embodiment provides a thermal sensor manufacturing system using ultrafine wires, including:

[0084] Control module: Used to control the capillary tube to rotate via the third drive motor, so that the wire from the coil frame passes through the wire needle and winds the wire into the capillary tube to be wound; and to control the second drive motor connected to the wire needle to rotate so that the wire needle is adjusted in position to guide the wire to move towards the capillary tube to be wound.

[0085] Adjustment module: used to acquire the tension of the wire collected by the tension sensor set in front of the wire needle during the winding process of the wire into the capillary tube, and control the first drive motor connected to the coil frame to adjust the rotation speed according to the acquired wire tension, so as to change the rotation speed of the coil frame and thus keep the wire tension within the preset tension range.

[0086] Judgment module: After the capillary winding is completed, it acquires an image of the capillary wire winding and determines whether there is a problem with the winding based on the image. If there is a problem, the location of the problem is marked; if there is no problem, the detection is completed. Example 3
