Description

Technical Field

[0001] The invention relates to the technical field of wire guide winding equipment, in particular to a wire winding collimation coaxial modulation system and a modulation method thereof. Background Art

[0002] Guidewires used in interventional medicine and some spring-type composite catheters need to have a certain degree of softness to ensure that the instruments can pass smoothly through tortuous blood vessels to reach the treatment lesions. Therefore, such products (interventional guidewires and interventional catheters) use spring-type structures in product structure design to ensure the flexibility of the products. The pitch of the spring is a key performance indicator of the spring. Different pitches will affect the rigidity of the spring. The accuracy of pitch control plays a key role in the overall performance of the final product, especially for some spring-type composite catheters. For such products, different pitches need to be designed at different positions according to clinical needs to meet clinical needs. The change of pitch at different positions is a progressive and small change, so when winding such springs, the change of pitch and the accuracy of pitch need to be precisely controlled.

[0003] For example, the Chinese authorized patent "A Wire Winding Device" with announcement number CN219669793U includes a main body and a spacing adjustment mechanism. Through the setting of the spacing adjustment mechanism, in the process of adjusting the spacing of the unwinding frame, the unwinding frame is first inserted into the first rotating block, and then the first fixed plate is pushed to the left according to the size of the unwinding frame. The first fixed plate drives the slider to slide to the left on the inner wall of the slide groove, so that the second rotating block is inserted into the other end of the unwinding frame to limit the unwinding frame, and then the first screw is screwed clockwise into the first threaded hole and the second threaded hole to fix the first fixed plate so that the first fixed plate is not easy to shake when the main body is working, and then one end of the silk thread is placed above the unwinding frame, and then the motor is started, and the motor drives the first rotating block and the unwinding frame to rotate through the rotating shaft.

[0004] Most of the above-mentioned existing technologies use dual motors to rotate synchronously to drive the axis rotation and realize the wire winding principle at the same time. The advantage of this structure is that it can be wound quickly and the spacing control is achieved by adjusting the motor speed. A more difficult problem in this system is how to achieve the coaxiality of the dual motors. When the spring winding shafts are not coaxial, the core between the two shafts will vibrate. The greater the centrifugation, the greater the vibration amplitude. This brings various random difficulties to the quality control of the wire winding. This is the main reason why the current wire winding has a scrap rate of more than 20%. Therefore, it does not meet the existing needs. In this regard, we propose a wire winding collimation coaxial modulation system and a modulation method thereof. Summary of the invention

[0005] The purpose of the present invention is to provide a wire winding alignment coaxial modulation system and a modulation method thereof, so as to solve the problem raised in the above background technology that the axis center vibrates greatly during the spring winding process due to different axes, which affects the wire winding quality.

[0012] Preferably, the plates of the input light limiting modulation system and the output light limiting modulation system are both made of aluminum, and the thickness of the plates of the input light limiting modulation system and the output light limiting modulation system is between ten and fifteen millimeters.

[0013] The modulation method of the wire winding collimation coaxial modulation system comprises the following steps:

[0014] Step 1: After installation, the third imaging system and the fourth imaging system are used to detect the verticality of the light-incoming limiting modulation system and the first wire winding chuck, and the verticality of the light-outgoing limiting modulation system and the second wire winding chuck. If the angle is within the range of ±.°, the next step of detection is performed. If it is unqualified, the new assembly will be modulated or replaced;

[0015] Step 2: After selecting and measuring a rotating shaft system that satisfies the conditions that the light entry limiting modulation system is perpendicular to the first wire winding chuck and the light exit limiting modulation system is perpendicular to the second wire winding chuck, firstly adjust the third adjustable base so that the axis is parallel to the horizontal line, rotate the light entry limiting modulation system and observe through the first imaging system so that the two first cylindrical row holes are at the lowest point and the highest point respectively;

[0016] Step 3, adjust the laser system so that the laser line emitted by the laser emission system passes vertically through the first cylindrical row of holes above. First, adjust the beam size limitation system so that the diameter of the laser beam is between 1 / 2 and 3 / 4 of the diameter of the first cylindrical row of holes. Adjust the first adjustable base so that the light spot passes through the first cylindrical row of holes above. Place the optical signal detection system behind and adjacent to the beam size limitation system. Modulate the second adjustable base so that the optical signal detection system detects the complete light spot and records the value E1. Translate the optical signal detection system to the first optical signal detection position, one side of the first cylindrical row of holes above, and record the value E2 of the detector. Compare E1 with E2. If they are inconsistent, modulate the first adjustable base so that E1 is the same as E2, so that the laser line passes vertically through the circular hole.

[0017] Step 4: Verify whether the first wire winding chuck is eccentric, rotate the light limiting modulation system, make the laser line pass through the first cylindrical hole below, test the energy E2, if the maximum value is the same as E1, the shaft is a concentric system, and continue to the next step of the test, if the value is different, reselect the first wire winding chuck and the light limiting modulation system, and repeat the above steps;

[0018] Step 5. Adjust the light output system so that the laser line emitted by the laser emission system passes vertically through the second cylindrical row of holes above. First, modulate the fourth adjustable base so that the axis of the second wire winding chuck is parallel to the horizontal line. Rotate the light output limit modulation system to observe through the second imaging system so that the second cylindrical row of holes below is at the lowest point, and thus the second cylindrical row of holes above is at the highest point. Translate the optical signal detection system to the position of the second optical signal detection position and align it with the second cylindrical row of holes above; modulate the fourth adjustable base so that the laser line emitted by the laser emission system passes through the second cylindrical row of holes above and records the detector value E3. Compare E3 with E1, and modulate the fourth adjustable base so that the two values ​​are the same.

[0019] Step 6: Verify whether the second wire winding chuck is eccentric, rotate the light limiting modulation system, and make the laser line pass through the remaining first imaging system holes in turn. Test the energy E3 each time. If the maximum value is the same as E1, the rotating shaft is a concentric system and the test is completed. If the values ​​are different, reselect the second wire winding chuck and the light limiting modulation system and repeat the above steps.

[0020] Step 7: Finally, the first wire winding chuck and the second wire winding chuck are coaxially adjusted, the input light limiting modulation system is perpendicular to the first wire winding chuck, and the output light limiting modulation system is perpendicular to the second wire winding chuck.

[0021] Compared with the prior art, the present invention has the following beneficial effects:

[0022] 1. The present invention combines laser and imaging technology to monitor and adjust the coaxiality of the rotating shaft in real time, ensuring that the two shafts maintain extremely high concentricity during high-speed operation, effectively reducing the vibration caused by centrifugation, thereby significantly improving the quality control level of wire winding products and reducing the scrap rate. The entire modulation process is highly automated, from parts detection, horizontal modulation, vertical modulation to coaxiality detection, all of which are completed through the coordination of visual inspection systems, servo motors and laser systems without manual intervention, greatly improving production efficiency and consistency.

[0023] 2. The present invention utilizes an optical signal detection system to monitor in real time the energy changes of the laser when it passes through a circular hole. By comparing the energy values ​​of the light spots at different positions, accurate judgment and adjustment of the coaxiality of the rotating shaft can be achieved to ensure the accuracy of the modulation results. The system supports the detection and modulation of multiple cylindrical holes one by one, and can adapt to rotating shaft systems of different specifications and requirements. At the same time, the parameter optimization system can perform intelligent analysis based on the database model and propose optimal control commands, thereby enhancing the flexibility and adaptability of the system.

[0024] 3. The present invention can significantly reduce the production cost of enterprises. At the same time, automated monitoring and modulation reduce the possibility of human operation errors, extend the service life of equipment, further reduce maintenance costs, reduce direct contact between workers and dangerous mechanical parts, and improve the safety of production operations.

[0033] Parts detection and selection are achieved through the AI ​​visual inspection system, which collects verticality parameters in real time, analyzes and makes judgments; the shaft linked to the servo motor is horizontally modulated in the light input modulation system, and the lowest and highest light-passing positions are found through the AI ​​visual inspection system; the vertical modulation of the laser and the light input system is achieved through energy monitoring by modulating the position, height, inclination and rotation parameters of the laser under a specific spot size, that is, after this modulation, the laser light will be parallel to the axis of the first wire winding chuck 4; the role of the shaft coaxial detection system is to ensure that the axis of the first wire winding chuck 4 rotates coaxially during the rotation process, and does not rotate centrifugally. If centrifugation occurs, the program will select the part, and energy detection is used in this part The system makes a judgment; the vertical modulation of the laser and the light-emitting system is achieved by modulating the position, height, inclination, rotation and other parameters of the second wire winding chuck 7 axis, and the vertical output of the laser is achieved through energy monitoring, that is, the laser light will be parallel to the second wire winding chuck 7 axis after this modulation is completed; the role of the rotating shaft coaxial detection system is to ensure that the second wire winding chuck 7 axis ensures coaxial rotation during the rotation process and is not centrifugal. If centrifugal occurs, the program will select parts, and a judgment is made in this part through the energy detection system; in the modulation process, the AI ​​parameter optimization system is used to analyze the correct behavior according to the model established in the database, and a control command is proposed, which is fed back to the central processing system. The modulation of the entire system is completed only when the coaxial rotation detection result of the light-emitting system is coaxial.

[0034] See also Figure 4The light input limiting modulation system 13 includes a first outer ring 21 and a first inner ring 22. The first outer ring 21 is located outside the first inner ring 22, and the first outer ring 21, the first inner ring 22 and the first wire winding chuck 4 are concentric circles. The upper and lower ends of the first inner ring 22 are provided with first cylindrical rows of holes 23 that pass through both sides of the light input limiting modulation system 13. The first imaging system 5 makes one of the first cylindrical rows of holes 23 located at the upper vertex and the other first cylindrical rows of holes 23 located at the lower vertex. The third imaging system 19 detects the verticality of the first wire winding chuck 4 and the light input limiting modulation system 13. By designing the first outer ring 21, the first inner ring 22 and the first wire winding chuck 4 as concentric circles and accurately setting the positions of the first cylindrical rows of holes 23 (one is located at the upper vertex and the other is located at the lower vertex), it is ensured that the laser can accurately pass through these holes for accurate coaxiality detection and modulation. This structural design effectively reduces the coaxial error caused by structural deviation, improves the stability of the wire winding process and product quality, and because the design of the light input limiting modulation system 13 has certain versatility and adjustability, it can adapt to wire winding chucks of different specifications and requirements. This flexibility enables the system to be widely used in various wire winding production scenarios.

[0035] See also Figure 4 , the light-exiting limiting modulation system 17 includes a second outer ring 25 and a second inner ring 26, the second outer ring 25 is located outside the second inner ring 26, and the second outer ring 25, the second inner ring 26 and the second wire winding chuck 7 belong to concentric circles, the second inner ring 26 is provided with six second cylindrical rows of holes 27 distributed in an annular shape, and the second cylindrical rows of holes 27 run through the light-exiting limiting modulation system 17, the second imaging system 16 makes one of the second cylindrical rows of holes 27 located at the upper vertex, and the other second cylindrical rows of holes 27 located at the lower vertex, and the fourth imaging system 20 detects the verticality of the second wire winding chuck 7 and the light-exiting limiting modulation system 17, and the light-exiting limiting modulation system 17 can more effectively control the coaxiality of the laser in the light-exiting stage. This design ensures that the laser can maintain consistent coaxiality when passing through cylindrical rows of holes at different positions, thereby improving the modulation accuracy and stability of the entire system, and the close cooperation between the second imaging system 16 and the light-exiting limiting modulation system 17 makes the detection of the verticality between the second wire winding chuck 7 and the light-exiting limiting modulation system 17 more accurate. Through real-time monitoring and adjustment, the system can quickly detect and correct verticality deviations, ensuring that the laser maintains the correct direction during the light emission process, avoiding laser deviation or scattering caused by verticality problems.

[0043] Step 3, adjust the laser system so that the laser line emitted by the laser emission system 9 passes vertically through the first cylindrical row of holes 23 above. First, adjust the beam size limiting system 10 so that the diameter of the laser beam is between 1 / 2 and 3 / 4 of the diameter of the first cylindrical row of holes 23. Adjust the first adjustable base 1 so that the light spot passes through the first cylindrical row of holes 23 above. Place the optical signal detection system 11 behind and adjacent to the beam size limiting system 10. Modulate the second adjustable base 2 so that the optical signal detection system 11 detects the complete light spot and records the value E1. Translate the optical signal detection system 11 to the first optical signal detection position 14, on one side of the first cylindrical row of holes 23 above, and record the value E2 of the detector. Compare E1 with E2. If they are inconsistent, modulate the first adjustable base 1 so that E1 is the same as E2, so that the laser line passes vertically through the circular hole.

First, modulate the fourth adjustable base 8 so that the axis of the second wire winding chuck 7 is parallel to the horizontal line. Rotate the light output limiting modulation system 17 to observe through the second imaging system 16 so that the second cylindrical row of holes 27 below is at the lowest point, and thus the second cylindrical row of holes 27 above is at the highest point. Translate the optical signal detection system 11 to the position of the second optical signal detection position 18, and align it with the second cylindrical row of holes 27 above; modulate the fourth adjustable base 8 so that the laser line emitted by the laser emission system 9 passes through the second cylindrical row of holes 27 above and records the detector value E3, compare E3 with E1, and modulate the fourth adjustable base 8 so that the two values ​​are the same;

[0046] Step 6: Verify whether the second winding chuck 7 is eccentric, rotate the light limiting modulation system 17, and make the laser line pass through the remaining first imaging system 5 holes in turn, and test the energy E3 each time. If the maximum value is the same as E1, the rotation axis is a concentric system and the test is completed; if the values ​​are different, reselect the second winding chuck 7 and the light limiting modulation system 17, and repeat the above steps;

Step 2: After selecting and measuring a rotating shaft system that satisfies the conditions that the light entry limiting modulation system (13) is perpendicular to the first wire winding chuck (4), and the light exit limiting modulation system (17) is perpendicular to the second wire winding chuck (7), firstly modulate the third adjustable base (3) so that the axis is parallel to the horizontal line, rotate the light entry limiting modulation system (13) and observe through the first imaging system (5) so that the two first cylindrical row holes (23) are respectively at the lowest point and the highest point; Step 3, adjust the laser system so that the laser line emitted by the laser emission system (9) passes vertically through the first cylindrical row of holes (23) above. First, adjust the beam size limiting system (10) so that the diameter of the laser beam is between 1 / 2 and 3 / 4 of the diameter of the first cylindrical row of holes (23). Adjust the first adjustable base (1) so that the light spot passes through the first cylindrical row of holes (23) above. Place the optical signal detection system (11) behind and adjacent to the beam size limiting system (10). Modulate the second adjustable base (2) so that the optical signal detection system (11) detects the complete light spot and records the value E1. Move the optical signal detection system (11) to the first optical signal detection position (14), one side of the first cylindrical row of holes (23) above, and record the value E2 of the detector. Compare E1 with E2. If they are inconsistent, modulate the first adjustable base (1) so that E1 is the same as E2. Thus, the laser line passes vertically through the circular hole. Step 4: Verify whether the first wire winding chuck (4) is eccentric, rotate the light input limiting modulation system (13), make the laser line pass through the first cylindrical row hole (23) below, test the energy E2, if the maximum value is the same as E1, the rotation axis is a concentric system, and continue to the next step of testing, if the values ​​are different, reselect the first wire winding chuck (4) and the light input limiting modulation system (13), and repeat the above steps; Step 5, adjust the light output system so that the laser line emitted by the laser emission system (9) passes vertically through the second cylindrical row of holes (27) above. First, modulate the fourth adjustable base (8) so that the axis of the second wire winding chuck (7) is parallel to the horizontal line. Rotate the light output limiting modulation system (17) to observe through the second imaging system (16) so that the second cylindrical row of holes (27) below is at the lowest point, and thus the second cylindrical row of holes (27) above is at the highest point. Shift the optical signal detection system (11) to the position of the second optical signal detection position (18) and align it with the second cylindrical row of holes (27) above; modulate the fourth adjustable base (8) so that the laser line emitted by the laser emission system (9) passes through the second cylindrical row of holes (27) above and record the detector value E3, compare E3 with E1, and modulate the fourth adjustable base (8) so that the two values ​​are the same; Step 6: Verify whether the second wire winding chuck (7) is eccentric, rotate the light output limiting modulation system (17), and make the laser line pass through the remaining first imaging system (5) holes in turn, and test the energy E3 each time. If the maximum value is the same as E1, the rotation axis is a concentric system and the test is completed; if the values ​​are different, reselect the second wire winding chuck (7) and the light output limiting modulation system (17), and repeat the above steps; Step seven, finally achieving coaxial adjustment of the first wire winding chuck (4) and the second wire winding chuck (7), the input light limiting modulation system (13) and the first wire winding chuck (4), and the output light limiting modulation system (17) and the second wire winding chuck (7).
