Description

Technical Field

[0001] This invention relates to the field of wire winding equipment technology, specifically to a wire winding collimation coaxial modulation system and its modulation method. Background Technology

[0002] To ensure the smooth passage of guidewires and some spring-loaded composite catheters used in interventional medicine to the treatment site through tortuous blood vessels, these products need to maintain a certain degree of flexibility. Therefore, these products (interventional guidewires and interventional catheters) employ a spring-loaded structure in their product design to guarantee flexibility. The pitch of the spring is a key performance indicator; different pitches affect the spring's rigidity. The precision of pitch control has a crucial impact on the overall performance of the final product, especially for some spring-loaded composite catheters. In these products, different pitches need to be designed for different positions to meet clinical needs. The changes in pitch at different positions are incremental and minute, so the pitch variation and accuracy must be precisely controlled when winding these springs.

[0003] For example, the Chinese authorized patent CN219669793U, entitled "A Wire Winding Device," includes a main body and a spacing adjustment mechanism. Through the spacing adjustment mechanism, during the adjustment of the spacing of the unwinding frame, the unwinding frame is first inserted into the first rotating block. Then, according to the size of the unwinding frame, the first fixing plate is pushed to the left. The first fixing plate causes the slider to slide to the left along the inner wall of the groove, allowing the second rotating block to be inserted into the other end of the unwinding frame for limiting its position. Then, the first screw is screwed clockwise into the first and second threaded holes to fix the first fixing plate, preventing it from shaking during operation. Finally, one end of the wire is placed above the unwinding frame, and the motor is started. The motor drives the first rotating block and the unwinding frame to rotate via a rotating shaft.

[0004] Most of the existing technologies mentioned above use dual motors to rotate synchronously and drive the shaft to rotate, thus realizing the winding principle. The advantage of this structure is that it can wind quickly, and the spacing can be controlled by adjusting the motor speed. A relatively difficult problem in this system is how to achieve coaxiality between the two motors. When the winding spring 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 winding, which is the main reason why the current winding has a scrap rate of more than 20%. Therefore, it does not meet the current requirements. In response, we propose a winding collimation coaxial modulation system and its modulation method. Summary of the Invention

[0005] The purpose of this invention is to provide a wire winding collimation coaxial modulation system and its modulation method to solve the problem mentioned in the background art, which is that the large vibration of the shaft center during the winding process due to different axes affects the winding quality.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a wire-wound collimation coaxial modulation system, comprising a first adjustable base, a second adjustable base, a third adjustable base, and a fourth adjustable base. A laser emitting system is mounted above the first adjustable base, and a light signal detection system is mounted above the second adjustable base. A first wire-wound chuck is mounted on one side of the third adjustable base.

An incident light limiting modulation system is fixedly mounted on the outside of the first wire-wound chuck. A second wire-wound chuck is mounted on one side of the fourth adjustable base. A servo motor mounted on the fourth adjustable base is connected to the shaft of the second wire-wound chuck via a coupling. An exit light limiting modulation system is fixedly mounted on the outside of the second wire-wound chuck. A first imaging system and a second imaging system are symmetrically mounted below the straight line containing the centers of the first and second wire-wound chucks. A third imaging system and a fourth imaging system are symmetrically mounted behind the straight line containing the centers of the first and second wire-wound chucks.

[0007] Preferably, the incident light limiting modulation system includes a first outer ring and a first inner ring. The first outer ring is located outside the first inner ring, and the first outer ring, the first inner ring, and the first wire-winding clamp are concentric circles. The upper and lower ends of the first inner ring are provided with first cylindrical holes that penetrate both sides of the incident light limiting modulation system. The first imaging system is configured such that one of the first cylindrical holes is located at the upper vertex and the other is located at the lower vertex. The third imaging system detects the perpendicularity between the first wire-winding clamp and the incident light limiting modulation system.

[0008] Preferably, the light emission limiting modulation system includes a second outer ring and a second inner ring. The second outer ring is located outside the second inner ring, and the second outer ring, the second inner ring, and the second wire winding clamp are concentric circles. The second inner ring has six second cylindrical holes arranged in a ring. The second cylindrical holes penetrate the light emission limiting modulation system. The second imaging system is configured such that one of the second cylindrical holes is located at the upper vertex and the other is located at the lower vertex. The fourth imaging system detects the perpendicularity between the second wire winding clamp and the light emission limiting modulation system.

[0009] Preferably, a beam size limiting system is installed on one side of the laser emitting system, a first optical signal detection position is provided on one side of the first cylindrical hole at the top of the first wire winding clamp, and a second optical signal detection position is provided on one side of the second cylindrical hole at the top of the second wire winding clamp, and the beam size limiting system, the first optical signal detection position and the second optical signal detection position are on the same laser emitting line.

[0010] Preferably, the first, second, third, and fourth adjustable bases are all equipped with X-axis, Y-axis, Z-axis, rotation, and tilt adjustment mechanisms.

[0011] Preferably, the laser emitting system, beam size limiting system, optical signal detection system, first imaging system, second imaging system, third imaging system and fourth imaging system are all connected to the central processing unit. The AI ​​parameter optimization system analyzes the behavior based on the model established in the database and issues control commands.

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

[0013] The modulation method of the wire-wound collimated coaxial modulation system includes the following steps:

[0014] Step 1: After installation, use the third and fourth imaging systems to check the perpendicularity between the incident light limiting modulation system and the first wire winding clamp, and the perpendicularity between the output light limiting modulation system and the second wire winding clamp. If the angle is within ±.°, proceed to the next step of testing. If it is not qualified, modulate or replace the new assembly.

[0015] Step 2: After selecting and measuring the rotating shaft system that satisfies the requirement that the incident light limiting modulation system is perpendicular to the first wire winding clamp and the exit light limiting modulation system is perpendicular to the second wire winding clamp, first modulate the third adjustable base to make the shaft parallel to the horizontal line, rotate the incident light limiting modulation system and observe through the first imaging system to make the two first cylindrical holes at the lowest and highest points respectively.

[0016] Step 3: Adjust the laser system so that the laser beam emitted by the laser emitting system passes perpendicularly through the first cylindrical aperture above. First, adjust the beam size limiting system so that the diameter of the laser beam is between 1 / 2 and 3 / 4 of the diameter of the first cylindrical aperture. Adjust the first adjustable base so that the light spot passes through the first cylindrical aperture above. Place the optical signal detection system behind and adjacent to the beam size limiting system. Modulate the second adjustable base so that the optical signal detection system detects the complete light spot and records the value E1. Move the optical signal detection system to the first optical signal detection position, to one side of the first cylindrical aperture above, and record the detector value E2. Compare E1 and E2. If they are inconsistent, adjust the first adjustable base so that E1 and E2 are the same. Thus, the laser beam passes perpendicularly through the aperture.

[0017] Step 4: Verify whether the first wire winding clamp is eccentric. Rotate the incident light limiting modulation system to make the laser line pass through the first cylindrical hole below and test the energy E2. If the maximum value is the same as E1, the rotating shaft is a concentric system and continue to the next test. If the values ​​are different, reselect the first wire winding clamp and the incident light limiting modulation system and repeat the above steps.

[0018] Step 5: Adjust the light emission system so that the laser line emitted by the laser emission system passes perpendicularly through the upper second cylindrical aperture. First, adjust the fourth adjustable base so that the axis of the second wire winding clamp is parallel to the horizontal line. Rotate the light emission limiting modulation system and observe through the second imaging system to bring the lower second cylindrical aperture to its lowest point, thus bringing the upper second cylindrical aperture to its highest point. Move the optical signal detection system to the position of the second optical signal detection position and align it with the upper second cylindrical aperture. Adjust the fourth adjustable base so that the laser line emitted by the laser emission system passes through the upper second cylindrical aperture and record the detector value E3. Compare E3 with E1, and adjust the fourth adjustable base to make the two values ​​the same.

[0019] Step 6: Verify whether the second wire winding clamp is eccentric. Rotate the light emission limiting modulation system so that the laser line passes through the remaining holes of the first imaging system in sequence. 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 complete. If the values ​​are different, reselect the second wire winding clamp and the light emission limiting modulation system, and repeat the above steps.

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

[0021] Compared with the prior art, the beneficial effects of the present invention are:

[0022] 1. This invention combines laser and imaging technologies 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. This effectively reduces vibration caused by centrifugation, thereby significantly improving the quality control level of the winding products and reducing the scrap rate. The entire modulation process is highly automated. From part inspection, horizontal modulation, vertical modulation to coaxiality detection, all are completed collaboratively by a vision inspection system, servo motor, and laser system without manual intervention, greatly improving production efficiency and consistency.

[0023] 2. This invention utilizes an optical signal detection system to monitor the energy change of a laser beam as it passes through a circular hole in real time. By comparing the energy values ​​of the laser spot at different positions, it achieves accurate judgment and adjustment of the coaxiality of the rotating shaft, ensuring 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 a database model and propose the optimal control command, enhancing the flexibility and adaptability of the system.

[0024] 3. This invention can significantly reduce production costs for enterprises. Simultaneously, automated monitoring and modulation reduce the possibility of human error, extend equipment lifespan, further reduce maintenance costs, decrease direct contact between workers and hazardous mechanical parts, and improve the safety of production operations.

[0031] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0032] Please see Figure 1-5 An embodiment of the present invention provides a wire-wound collimation coaxial modulation system, comprising a first adjustable base 1, a second adjustable base 2, a third adjustable base 3, and a fourth adjustable base 8. A laser emitting system 9 is mounted above the first adjustable base 1, and an optical signal detection system 11 is mounted above the second adjustable base 2. A first wire-wound chuck 4 is mounted on one side of the third adjustable base 3. A servo motor built into the third adjustable base 3 is connected to the shaft of the first wire-wound chuck 4 via a coupling. An incident light limiter is fixedly mounted on the outside of the first wire-wound chuck 4. The modulation system 13, the second wire winding chuck 7 is installed on one side of the fourth adjustable base 8, the servo motor of the fourth adjustable base 8 is connected to the shaft of the second wire winding chuck 7 through a coupling, the light emission limiting modulation system 17 is fixedly installed on the outside of the second wire winding chuck 7, the first imaging system 5 and the second imaging system 16 are symmetrically installed below the straight line where the centers of the first wire winding chuck 4 and the second wire winding chuck 7 are located, and the third imaging system 19 and the fourth imaging system 20 are symmetrically installed behind the straight line where the centers of the first wire winding chuck 4 and the second wire winding chuck 7 are located.

[0033] Part inspection and selection are achieved through an AI vision inspection system, which collects, analyzes, and judges verticality parameters in real time. The incident light modulation system horizontally modulates the shaft connected to the servo motor and uses the AI ​​vision inspection system to find the lowest and highest light-passing positions. Vertical modulation of the laser and incident light system is achieved by modulating parameters such as the laser's position, height, tilt angle, and rotation under a specific spot size. Energy monitoring ensures vertical modulation of the laser, meaning that after modulation, the laser beam will be parallel to the axis of the first wire-winding chuck 4. The coaxial detection system ensures that the shaft of the first wire-winding chuck 4 rotates coaxially and without centrifugation. If centrifugation occurs, the program selects the part. This part uses energy detection... The system makes a judgment; the vertical modulation of the laser and the output system is achieved by modulating parameters such as the position, height, tilt angle, and rotation of the second wire-winding chuck 7 axis, and by monitoring energy to realize the vertical output of the laser. That is, after this modulation, the laser beam will be parallel to the second wire-winding chuck 7 axis; the function of the coaxial detection system is to ensure that the second wire-winding chuck 7 axis rotates coaxially and does not centrifugate during rotation. If centrifugation occurs, the program will select the part. In this part, the energy detection system makes a judgment; during the modulation process, the AI ​​parameter optimization system analyzes the correct behavior based on the model established in the database, proposes control commands, and feeds them back to the central processing system. Only when the coaxial rotation detection result of the output system is coaxial is the modulation of the entire system completed.

[0034] Please see Figure 4The incident light 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 clamp 4 are concentric circles. The upper and lower ends of the first inner ring 22 are provided with first cylindrical holes 23 that penetrate both sides of the incident light limiting modulation system 13. The first imaging system 5 makes one of the first cylindrical holes 23 located at the upper vertex and the other at the lower vertex. The third imaging system 19 detects the perpendicularity between the first wire-winding clamp 4 and the incident light limiting modulation system 13. By designing the first outer ring 21, the first inner ring 22, and the first wire-winding clamp 4 as concentric circles and precisely setting the positions of the first cylindrical holes 23 (one at the upper vertex and the other at the lower vertex), it is ensured that the laser can accurately pass through these holes for precise coaxiality detection and modulation. This structural design effectively reduces coaxial errors caused by structural deviations, improving the stability of the winding process and product quality. Because the incident light limiting modulation system 13 has a certain degree of versatility and adjustability, it can adapt to winding chucks of different specifications and requirements. This flexibility allows the system to be widely applied in various winding production scenarios.

[0035] Please see Figure 4 The light emission 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 clamp 7 are concentric circles. The second inner ring 26 has six second cylindrical apertures 27 arranged in a ring, which penetrate the light emission limiting modulation system 17. The second imaging system 16 positions one of the second cylindrical apertures 27 at the upper vertex and the other at the lower vertex. The fourth imaging system 20 detects the perpendicularity between the second wire-winding clamp 7 and the light emission limiting modulation system 17. The light emission limiting modulation system 17 can more effectively control the coaxiality of the laser during the light emission stage. This design ensures that the laser maintains consistent coaxiality when passing through the cylindrical apertures at different positions, thereby improving the modulation accuracy and stability of the entire system. The close cooperation between the second imaging system 16 and the light emission limiting modulation system 17 makes the detection of the perpendicularity between the second wire-winding clamp 7 and the light emission 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 emission process and avoiding laser deflection or scattering caused by verticality issues.

[0036] Please see Figure 1 and Figure 2A beam size limiting system 10 is installed on one side of the laser emitting system 9. A first optical signal detection position 14 is provided on one side of the first cylindrical hole 23 at the apex of the first wire winding clamp 4, and a second optical signal detection position 18 is provided on one side of the second cylindrical hole 27 at the apex of the second wire winding clamp 7. The beam size limiting system 10, the first optical signal detection position 14, and the second optical signal detection position 18 are all located on the same laser emitting line 12. The installation of the beam size limiting system 10 ensures that the laser beam can be precisely sized before emission, guaranteeing the accuracy and consistency of the laser beam in subsequent processing.

[0037] Please see Figure 1 The first adjustable base 1, the second adjustable base 2, the third adjustable base 3, and the fourth adjustable base 8 are all equipped with X-axis, Y-axis, Z-axis, rotation, and tilt adjustment mechanisms. Through precise X-axis, Y-axis, and Z-axis adjustments, the accurate positioning of system components in three-dimensional space can be ensured. Rotation and tilt adjustments further ensure the accuracy of the orientation and angle of system components. This multi-dimensional adjustment capability greatly improves the flexibility and adaptability of the system.

[0038] Furthermore, the laser emission system 9, the beam size limiting system 10, the optical signal detection system 11, the first imaging system 5, the second imaging system 16, the third imaging system 19, and the fourth imaging system 20 are all connected to the central processing unit. The AI ​​parameter optimization system analyzes the behavior based on the model established in the database and issues control commands.

[0039] Furthermore, both the input light limiting modulation system 13 and the output light limiting modulation system 17 are made of aluminum, and the thickness of the input light limiting modulation system 13 and the output light limiting modulation system 17 is between ten and fifteen millimeters.

[0040] The modulation method of the wire-wound collimated coaxial modulation system includes the following steps:

[0041] Step 1: After installation, the perpendicularity of the incident light limiting modulation system 13 to the first wire winding clamp 4 and the exit light limiting modulation system 17 to the second wire winding clamp 7 are checked by the third imaging system 19 and the fourth imaging system 20, respectively. If the angle is within the range of 90±0.01°, the next step of the test is carried out. If it is not qualified, the new assembly will be modulated or replaced.

[0042] Step 2: After selecting and measuring the rotating shaft system that satisfies the condition that the incident light limiting modulation system 13 is perpendicular to the first wire winding clamp 4 and the exit light limiting modulation system 17 is perpendicular to the second wire winding clamp 7, the third adjustable base 3 is first modulated to make the shaft parallel to the horizontal line. The incident light limiting modulation system 13 is then rotated and observed through the first imaging system 5 to make the two first cylindrical holes 23 at the lowest and highest points, respectively.

[0043] Step 3: Adjust the laser system so that the laser line emitted by the laser emitting system 9 passes perpendicularly through the upper first cylindrical aperture 23. 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 aperture 23. Adjust the first adjusting base 1 so that the light spot passes through the upper first cylindrical aperture 23. Place the optical signal detection system 11 behind and adjacent to the beam size limiting system 10. Modulate the second adjusting 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, to one side of the upper first cylindrical aperture 23, and record the detector value E2. Compare E1 and E2. If they are inconsistent, modulate the first adjusting base 1 so that E1 and E2 are the same. Thus, the laser line passes perpendicularly through the aperture.

[0044] Step 4: Verify whether the first wire winding clamp 4 is eccentric. Rotate the light-limiting modulation system 13 to make the laser line pass through the first cylindrical hole 23 below and test the energy E2. If the maximum value is the same as E1, the rotating shaft is a concentric system and the next test is performed. If the values ​​are different, the first wire winding clamp 4 and the light-limiting modulation system 13 are selected again and the above steps are repeated.

[0045] Step 5: Adjust the light emission system so that the laser line emitted by the laser emission system 9 passes perpendicularly through the upper second cylindrical aperture 27. First, modulate the fourth adjustable base 8 so that the axis of the second wire winding clamp 7 is parallel to the horizontal line. Rotate the light emission limiting modulation system 17 to observe through the second imaging system 16, so that the lower second cylindrical aperture 27 is at its lowest point, and thus the upper second cylindrical aperture 27 is at its highest point. Move the optical signal detection system 11 to the position of the second optical signal detection position 18 and align it with the upper second cylindrical aperture 27; modulate the fourth adjustable base 8 so that the laser line emitted by the laser emission system 9 passes through the upper second cylindrical aperture 27 and record the detector value E3. Compare E3 with E1, and modulate the fourth adjustable base 8 to make the two values ​​the same.

[0046] Step 6: Verify whether the second wire winding clamp 7 is eccentric. Rotate the light emission limiting modulation system 17 so that the laser line passes through the remaining holes of the first imaging system 5 in sequence. 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 clamp 7 and the light emission limiting modulation system 17, and repeat the above steps.

[0047] Step 7: Finally, the first wire-winding clamp 4 and the second wire-winding clamp 7 are aligned coaxially, the input light limiting modulation system 13 is perpendicular to the first wire-winding clamp 4, and the output light limiting modulation system 17 is perpendicular to the second wire-winding clamp 7.

Adjust the first adjustable base (1) so that the light spot passes through the first cylindrical aperture (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 position of the first optical signal detection position (14), to one side of the first cylindrical aperture (23) above, and record the detector value E2. Compare E1 and E2. If they are inconsistent, modulate the first adjustable base (1) so that E1 and E2 are the same. Thus, the laser line passes perpendicularly through the aperture. Step 4: Verify whether the first wire winding clamp (4) is eccentric. Rotate the incident light limiting modulation system (13) to make the laser line pass through the first cylindrical hole (23) below. Test the energy E2. If the maximum value is the same as E1, the rotating shaft is a concentric system. Continue to the next test. If the values ​​are different, reselect the first wire winding clamp (4) and the incident light 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 upper second cylindrical aperture (27). First, modulate the fourth adjustable base (8) so that the axis of the second wire winding clamp (7) is parallel to the horizontal line. Rotate the light output limiting modulation system (17) and observe through the second imaging system (16) so that the lower second cylindrical aperture (27) is at its lowest point, and thus the upper second cylindrical aperture (27) is at its highest point. Move the optical signal detection system (11) to the position of the second optical signal detection position (18) and align it with the upper second cylindrical aperture (27). Modulate the fourth adjustable base (8) so that the laser line emitted by the laser emission system (9) passes through the upper second cylindrical aperture (27) 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 clamp (7) is eccentric. Rotate the light-exit limiting modulation system (17) so that the laser line passes through the remaining holes of the first imaging system (5) in sequence. 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 clamp (7) and the light-exit limiting modulation system (17) and repeat the above steps. Step 7: Finally, the first wire-winding clamp (4) and the second wire-winding clamp (7) are aligned coaxially, the input light limiting modulation system (13) is perpendicular to the first wire-winding clamp (4), and the output light limiting modulation system (17) is perpendicular to the second wire-winding clamp (7).
