Description

Technical Field

[0001] This application relates to the field of winding machine technology, and in particular to a fully automatic winding machine. Background Technology

[0002] A fully automatic winding machine generally includes a main body, a pay-off roller, a winding rotor, and a tensioning mechanism. The pay-off roller, winding rotor, and tensioning mechanism are all mounted on the main body. The pay-off rotor rotates to release the enameled wire, which is then tensioned by the tensioning mechanism and wound onto the winding rotor to complete the automatic winding.

[0003] Existing tensioning mechanisms typically consist of a spring, a push rod, and a pulley. The pulley is rotatably connected to the push rod, which is slidably connected to the main body. The spring is fitted onto the push rod, with one end connected to the push rod and the other end connected to the main body. After the enameled wire is released from the pay-off roller, it passes over the pulley and winds onto the rotor. The tension is determined by the spring's elastic coefficient. If the elastic coefficient is too small, it will not provide tension. If the elastic coefficient is too large, during initial operation, the rotor rotates, and the enameled wire is wound onto the rotor. Since the rotor and pay-off roller are controlled independently, there may be a situation where the rotor starts first, followed by the pay-off roller. In this case, the spring in the tensioning mechanism is compressed. The greater the compression of the spring (the elastic force gradually increases), the greater the tension on the enameled wire. When this tension exceeds the tensile limit of the enameled wire, it will break. This is because a large elastic coefficient results in a variable elastic force, leading to a small buffer stroke for the enameled wire to be compressed, causing it to break before the rotor and pay-off roller rotate synchronously. Therefore, the adjustment range of this type of tensioning structure fully automatic winding machine is limited, and it is prone to wire breakage. Summary of the Invention

[0004] To solve the aforementioned wire breakage problem, this application provides a fully automatic winding machine.

[0005] This application provides a fully automatic winding machine, which adopts the following technical solution:

[0006] A fully automatic winding machine includes a main body and a wire feeding mechanism, a tensioning mechanism, and a winding mechanism sequentially arranged on the main body. The tensioning mechanism includes a tensioning wheel, a push rod, a first friction assembly, and a second friction assembly. The tensioning wheel is mounted on the push rod. The first friction assembly includes a first driving wheel, a first driven wheel, and a first friction belt. The first driving wheel and the first driven wheel are rotatably connected to the main body, and the first friction belt is wound around the first driving wheel and the first driven wheel. The second friction assembly includes a second driving wheel, a second driven wheel, and a second friction belt. The second driving wheel and the second driven wheel are rotatably connected to the main body, and the second friction belt is wound around the second driving wheel and the second driven wheel. The push rod is clamped between the first friction belt and the second friction belt.

[0007] By adopting the above technical solution, during initial operation, the enameled wire wraps around the tensioning mechanism and onto the winding roller. The first driving wheel drives the first driven wheel and the first friction belt to move. The first friction belt generates sliding friction with the push rod, causing the push rod to generate an upward frictional force. The second driving wheel drives the second driven wheel and the second friction belt to move. The second friction belt generates sliding friction with the push rod, causing the push rod to generate another upward frictional force. At this time, the push rod is in its highest position. When neither the pay-off roller nor the winding roller rotates, the tension on the enameled wire cancels out the frictional force on the push rod, and the tension on the enameled wire is less than the ultimate tension of the enameled wire. When the winding roller rotates first, the enameled wire is wound onto the winding roller. When the pay-off roller is not yet rotating, the push rod moves downward under the tension of the enameled wire. At this time, the friction force on the push rod still cancels out the tension of the enameled wire, because the magnitude of the tension of the enameled wire is determined by the magnitude of the friction force on the push rod. However, the friction force on the push rod remains constant. By setting the buffer stroke of the push rod, the tension of the enameled wire can always be less than the ultimate tension of the enameled wire, greatly reducing the occurrence of wire breakage. Secondly, the buffer stroke of the push rod is determined by the length of the push rod. Increasing the length of the push rod can increase the buffer stroke of the push rod, which has a larger adjustment range than using a spring for adjustment and is less likely to cause wire breakage.

[0008] Optionally, the main body is equipped with a first drive source for driving the first drive wheel to rotate and a second drive source for driving the second drive wheel to rotate.

[0009] By adopting the above technical solution, the first drive source drives the first driving wheel to rotate, thereby driving the first driven wheel and the first friction belt to move, and the second drive source drives the second driving wheel to rotate, thereby driving the second driven wheel and the second friction belt to move.

[0010] Optionally, a slide rod is fixedly connected to the main body, and a long strip-shaped groove is opened on the top rod along the moving direction of the top rod, and the slide rod is slidably connected in the groove.

[0011] By adopting the above technical solution, the slide rod is fixed on the main body. When the top rod moves up and down, the slide rod slides in the slide groove, so that the top rod slides along the slide groove and the direction of slide rod movement, preventing the top rod from detaching from the first friction zone and the second friction zone during the movement.

[0012] Optionally, the main body is also provided with an adjustment mechanism for adjusting the friction between the top rod and the first friction belt. The adjustment mechanism includes a pressure plate, an adjustment screw and a slide block. The slide block is fixedly connected to the main body, the pressure plate is slidably connected to the slide block, the adjustment screw is threadedly connected to the slide block, one end of the adjustment screw abuts against the pressure plate, and the side of the pressure plate away from the slide block abuts against the first friction belt.

[0013] By adopting the above technical solution, the tension force provided by the tensioning mechanism is determined by the friction force on the push rod. The magnitude of the friction force on the push rod is determined by the clamping force of the first friction belt and the second friction belt on the push rod. The greater the clamping force of the first friction belt and the second friction belt on the push rod, the greater the dynamic friction force between the first friction belt and the push rod and the dynamic friction force between the second friction belt and the push rod. When the tension force of the tensioning mechanism is too small, rotating the adjusting screw causes the pressure plate to push the first friction belt towards the push rod, increasing the clamping force of the first friction belt and the second friction belt on the push rod, thus increasing the friction force on the push rod and ultimately increasing the tension force of the tensioning mechanism. When the tension force of the tensioning mechanism is too large, rotating the adjusting screw in the opposite direction causes the pressure plate to push the first friction belt away from the push rod, reducing the clamping force of the first friction belt and the second friction belt on the push rod, thus decreasing the friction force on the push rod and ultimately reducing the tension force of the tensioning mechanism.

[0014] Optionally, the wire feeding mechanism includes a wire feeding roller and a third drive source. The wire feeding roller is rotatably connected to the main body, and the third drive source is mounted on the main body and is used to drive the wire feeding roller to rotate.

[0015] By adopting the above technical solution, when wire feeding is required, the third drive source drives the feeding roller to rotate to feed the wire.

[0016] Optionally, the winding mechanism includes a winding roller and a fourth drive source, the winding roller being rotatably connected to the main body, and the fourth drive source being mounted on the main body and used to drive the winding roller to rotate.

[0017] By adopting the above technical solution, when the winding mechanism is working, the fourth drive source drives the winding roller to rotate for winding.

[0018] Optionally, a rack is installed at the end of the push rod away from the tensioning wheel, a gear is installed on the main body, the gear meshes with the rack, and an electronic throttle is also installed on the main body. The electronic throttle is coaxially fixed with the gear and electrically connected to the third drive source.

[0019] By adopting the above technical solution, the electronic throttle adjusts the output current by its own rotation angle. The larger the rotation angle, the larger the output current. The third drive source controls the rotation speed through the current; when the current is small, the third drive source rotates slowly, and when the current is large, the third drive source rotates quickly. When the push rod moves downward, it drives the rack downward, thereby driving the gear and the electronic throttle to rotate, increasing the angle of the electronic throttle and accelerating the unwinding of the enameled wire. When the unwinding enameled wire exceeds the winding wire, the tensioning mechanism controls the push rod to move upward for tensioning. When the push rod moves upward, it drives the rack upward, thereby driving the gear and the electronic throttle to rotate in the opposite direction. This process repeats until the push rod and rack stabilize at a suitable position, and the electronic throttle stabilizes at a suitable angle. At this point, the unwinding speed equals the winding speed. Automatic adjustment of the unwinding speed of the unwinding roller is achieved by setting the gear, rack, and electronic throttle.

[0020] Optionally, the push rod is provided with a wear-resistant layer on the side corresponding to the first friction strip and the second friction strip.

[0021] By adopting the above technical solution, the wear-resistant layer has wear-resistant properties. When the first friction band and the second friction band rub against the wear-resistant layer on both sides of the push rod, the wear-resistant layer is not easy to wear, which extends the service life of the push rod and reduces the probability of the push rod failing.

[0022] Optionally, the main body is also provided with a first guide wheel and a second guide wheel. Both the first guide wheel and the second guide wheel are rotatably connected to the main body. The first guide wheel is located between the wire feeding mechanism and the tensioning mechanism to guide the wire entering the tensioning mechanism, and the second guide wheel is located between the tensioning mechanism and the winding mechanism to guide the wire exiting the tensioning mechanism.

[0023] By adopting the above technical solution, the first guide wheel guides the wire entering the tensioning mechanism, so that the enameled wire can be smoothly transferred from the unwinding roller to the tensioning wheel on the tensioning mechanism. The second guide wheel guides the wire exiting the tensioning mechanism, so that the enameled wire can be smoothly transferred from the tensioning wheel to the winding roller. The setting of the first guide wheel and the second guide wheel ensures that the tensioning mechanism can work normally.

[0024] In summary, this application includes the following beneficial technical effects:

[0025] 1. During the tensioning process, the tension force is constant and less than the ultimate tensile force of the enameled wire, which reduces the probability of wire breakage. Secondly, the buffer stroke of the push rod is determined by the length of the push rod. By increasing the length of the push rod, the buffer stroke of the push rod can be increased. Compared with the adjustment using a spring, the adjustment range is larger and the wire breakage is less likely to occur.

[0026] 2. This application achieves the adjustment of the tension force of the tensioning mechanism by rotating the adjusting screw, causing the pressure plate to push the first friction belt closer to or away from the top rod. Attached Figure Description

Detailed Implementation

[0033] The following is in conjunction with the appendix Figure 1-4 This application will be described in further detail.

[0034] This application discloses a fully automatic winding machine, referring to... Figure 1 and Figure 2The fully automatic winding machine includes a main body 1 and a wire feeding mechanism 2, a tensioning mechanism 3, and a winding mechanism 4 sequentially arranged on the main body 1. The tensioning mechanism 3 includes a tensioning wheel 31, a push rod 32, a first friction assembly 33, and a second friction assembly 34. The tensioning wheel 31 is rotatably mounted on the push rod 32 via rolling bearings. The first friction assembly 33 includes a first driving wheel 331, a first driven wheel 332, and a first friction belt 333. The first driving wheel 331 and the first driven wheel 332 are both rotatably connected to the main body 1. The first friction belt 333 winds... The first driving wheel 331 and the first driven wheel 332 are mounted on the first driving wheel 331 and the first driven wheel 332. The second friction assembly 34 includes a second driving wheel 341, a second driven wheel 342 and a second friction belt 343. The second driving wheel 341 and the second driven wheel are rotatably connected to the main body 1. The second friction belt 343 is wound around the second driving wheel 341 and the second driven wheel 342. The push rod 32 is clamped between the first friction belt 333 and the second friction belt 343. The push rod 32 is tensioned upward by the friction force provided by the first friction belt 333 and the second friction belt 343.

[0035] During initial operation, the enameled wire 17 is wound around the tensioning mechanism 3 and onto the winding roller 41. The first driving wheel 331 drives the first driven wheel 332 and the first friction belt 333 to move. The first friction belt 333 generates sliding friction with the push rod 32, causing the push rod 32 to generate an upward frictional force. The second driving wheel 341 drives the second driven wheel 342 and the second friction belt 343 to move. The second friction belt 343 generates sliding friction with the push rod 32, causing the push rod 32 to generate another upward frictional force. The resultant force of the two frictional forces is the upward tensioning force of the push rod 32, causing the push rod 32 to move upward and tension the enameled wire 17. When neither the unwinding roller 21 nor the winding roller 41 rotates, the tension on the enameled wire 17 cancels out the frictional force on the push rod 32, and the tension on the enameled wire 17 is less than the ultimate tension of the enameled wire 17. At this time, the push rod 32 is in its highest position. When the winding roller 41 rotates first... When the enameled wire 17 is wound on the winding roller 41 and the unwinding roller 21 has not yet rotated, the push rod 32 moves downward under the tension of the enameled wire 17. At this time, the friction force on the push rod 32 still cancels out the tension of the enameled wire 17, because the magnitude of the tension of the enameled wire 17 is determined by the magnitude of the friction force on the push rod 32. However, the friction force on the push rod 32 remains constant. By setting the buffer stroke of the push rod 32, the tension of the enameled wire 17 can always be less than the limit tension of the enameled wire 17, which greatly reduces the occurrence of wire breakage. In other words, the tension of the enameled wire 17 remains constant during the downward movement of the push rod 32. Thus, the buffer stroke of the enameled wire 17 can be increased by controlling the downward distance of the push rod 32, so that when the unwinding roller 21 and the winding roller 41 rotate synchronously, the enameled wire 17 will not be pulled apart by the reaction force of the tensioning mechanism 3. The buffer stroke of the push rod 32 is the distance that the push rod 32 can move downward. The greater the downward distance that the push rod 32 can move, the greater the adjustment range of the tensioning mechanism 3. Therefore, the buffer stroke of the tensioning mechanism 3 is determined by the length of the push rod 32. By increasing the length of the push rod 32, the buffer stroke of the push rod 32 can be increased, resulting in a larger adjustment range compared to the existing design that uses a spring for adjustment.

[0036] Reference Figure 2 and Figure 4The main body 1 is equipped with a first drive source 5, which drives the first driving wheel 331 to rotate. A second drive source 6 is also installed on the main body 1, which drives the second rotating wheel to rotate. The first drive source 5 drives the first rotating wheel to rotate, causing the first driven wheel 332 and the first friction belt 333 to move, resulting in dynamic friction between the first friction belt 333 and the push rod 32, generating an upward frictional force on the push rod 32. The second drive source 6 drives the second rotating wheel to rotate, causing the second driven wheel 342 and the second friction belt 343 to move, resulting in dynamic friction between the second friction belt 343 and the push rod 32, also providing an upward frictional force to the push rod 32. In this embodiment, both the first drive source 5 and the second drive source 6 are electric motors. In other embodiments, the first drive source 5 and the second drive source 6 can also be hydraulic motors, micro-engines, or other mechanisms or components that can provide rotational power. As an alternative to this embodiment, the first drive source 5 and the second drive source 6 can both be electric motors or both be hydraulic motors. In other embodiments, they can also be different, such as the first drive source 5 being an electric motor and the second drive source 6 being a hydraulic motor.

[0037] Reference Figure 2 and Figure 3 A sliding rod 7 is fixedly connected to the main body 1. A long groove 8 is opened on the top rod 32 along the moving direction of the top rod 32. When the top rod 32 slides up and down, the sliding rod 7 is slidably connected in the groove 8 to prevent the top rod 32 from deviating from the main body 1 when sliding up and down. If the top rod 32 deviates from the main body 1, the enameled wire 17 may slip out from the tensioning wheel 31 on the top rod 32. Once the enameled wire 17 slips out of the tensioning wheel 31, it loses its tensioning effect, which will cause the enameled wire 17 wound by the winding roller 41 to be relatively loose, which does not meet the production requirements. On the other hand, after the top rod 32 loses the tension of the enameled wire 17, it will continue to move upward, causing damage to the device.

[0038] Reference Figure 2 and Figure 3The main body 1 is equipped with an adjustment mechanism 9 for adjusting the friction between the top rod 32 and the first friction band 333. The adjustment mechanism 9 includes a pressure plate 91, an adjusting screw 92, and a slide 93. The slide 93 is fixedly connected to the main body 1, the pressure plate 91 is slidably connected to the slide 93, and the adjusting screw 92 is threadedly connected to the slide 93. One end of the adjusting screw 92 abuts against the pressure plate 91, and the side of the pressure plate 91 away from the slide 93 abuts against the first friction band 333. When the tension of the tensioning mechanism 3 is small, the adjusting screw 92 is rotated, causing the end of the adjusting screw 92 that abuts against the pressure plate 91 to push the pressure plate 91 towards the top rod 32. This causes the pressure plate 91 to push the first friction band 333 against the top rod 32, increasing the pressure to increase the friction. Since the tension is provided by the friction, the tension is adjusted by adjusting the nut. When the tension is too large, the adjusting nut is rotated in the opposite direction. The push rod 32 has a wear-resistant layer 13 on its side corresponding to the first friction band 333 and the second friction band 343. By setting the wear-resistant layer 13, the wear resistance of the push rod 32 is improved. When the first friction band 333 and the second friction band 343 rub against the wear-resistant layer 13 on the push rod 32, the wear-resistant layer 13 can extend the service life of the push rod 32 because of its wear-resistant properties.

[0039] Reference Figure 1 The wire feeding mechanism 2 includes a wire feeding roller 21 and a third drive source 22. The wire feeding roller 21 is rotatably connected to the main body 1, and the third drive source 22 is mounted on the main body 1 and is used to drive the wire feeding roller 21 to rotate.

[0040] Reference Figure 2 and Figure 3A rack 10 is installed at the end of the push rod 32 away from the tension wheel 31. The rack 10 is installed in the same direction as the push rod 32. A gear 11 is installed on the main body 1. The gear 11 is rotatably installed on the main body 1 through a bearing. The gear 11 meshes with the rack 10. An electronic throttle 12 is also installed on the main body 1. The electronic throttle 12 is coaxially and fixedly connected to the gear 11. When the gear 11 rotates, it will drive the electronic throttle 12 to rotate, so that the electronic throttle 12 can detect the change in its own rotation angle. The electronic throttle 12 is electrically connected to the third drive source 22. The electronic throttle 12 adjusts the output current by its own rotation angle. The larger the rotation angle, the larger the output current. The third drive source 22 controls the rotation speed by the current. When the current is small, the third drive source 22 rotates slowly. When the current is large, the third drive source 22 rotates faster. Therefore, the electronic throttle 12 can control the rotation speed of the third drive source 22 by detecting the angle. The larger the angle detected by the electronic throttle 12, the larger the current output by the electronic throttle 12, and the faster the rotation speed of the third drive source 22. When the push rod 32 moves downward, it drives the rack 10 downward, which in turn drives the gear 11 and the electronic throttle 12 to rotate, increasing the angle of the electronic throttle 12. This causes the third drive source 22 to increase the speed of the pay-off roller 21, accelerating the pay-off of the enameled wire 17. When the pay-off of the enameled wire 17 exceeds the take-up of the enameled wire 17, the tensioning mechanism 3 controls the push rod 32 to move upward for tensioning. Conversely, when the push rod 32 moves upward, it drives the rack 10 upward, causing the gear 11 and the electronic throttle 12 to rotate in opposite directions, decreasing the angle of the electronic throttle 12. This slows down the speed of the pay-off roller 21, reducing the pay-off of the enameled wire 17. This process repeats until the push rod 32 and rack 10 stabilize at a suitable position, and the electronic throttle 12 stabilizes at a suitable angle. At this point, the pay-off speed equals the take-up speed. Automatic adjustment of the pay-off speed of the pay-off roller 21 is achieved by setting the gear 11, rack 10, and electronic throttle 12. In this embodiment, the third drive source 22 is an electric motor. In other embodiments, the third drive source 22 can also be a hydraulic motor, a micro-engine, or other mechanism or component that can provide rotational power. The electronic throttle 12 contains a Hall element, which converts the rotation angle signal into a current control signal to control the magnitude of the output current.

[0041] Reference Figure 2The winding mechanism 4 includes a winding roller 41 and a fourth drive source 42. The winding roller 41 is rotatably connected to the main body 1 via bearings, and the fourth drive source 42 is detachably mounted on the main body 1 via fastening bolts. The output shaft of the fourth drive source 42 is coaxially connected to the winding roller 41 via a coupling. The fourth drive source 42 is used to drive the winding roller 41 to rotate for winding operations. In this embodiment, the fourth drive source 42 is a motor. In other embodiments, the fourth drive source 42 can also be a hydraulic motor, a micro-engine, or other mechanisms or components that can provide rotational power.

[0042] Reference Figure 2 The main body 1 is also provided with a first guide wheel 14, a second guide wheel 15 and a third guide wheel 16. The first guide wheel 14, the second guide wheel 15 and the third guide wheel are all rotatably connected to the main body 1 through rolling bearings. The first guide wheel 14 is located between the wire feeding mechanism 2 and the tensioning mechanism 3, so that the enameled wire 17 is fed from the wire feeding roller 21 on the wire feeding mechanism 2 and then guided by the first guide wheel 14 to the tensioning wheel 31, so as to guide the wire entering the tensioning mechanism 3. The second guide wheel 15 is located between the tensioning mechanism 3 and the third guide wheel 16. The enameled wire 17 is led out from the tensioning wheel 31, passes around the second guide wheel 15, and is guided to the third guide wheel 16. The first guide wheel 14 and the second guide wheel 15 are located on both sides of the push rod 32. When the push rod 32 and the tensioning wheel 31 move upward, the enameled wire 17 forms a fold-back section between the first guide wheel 14, the tensioning wheel 31, and the second guide wheel 15. When the winding speed of the winding roller 41 is faster than the unwinding speed of the unwinding roller 21, the push rod 32 can be moved downward to release the enameled wire 17 in the fold-back section, preventing the enameled wire 17 from being broken. The third guide wheel 16 is located between the second guide wheel 15 and the winding roller 41. The enameled wire 17 led out from the second guide wheel 15 is guided by the third guide wheel 16 and wound onto the winding roller 41, facilitating normal winding of the winding roller 41.

[0043] The implementation principle of a fully automatic winding machine according to an embodiment of this application is as follows: During initial operation, the winding roller 41 may start before the unwinding roller 21. When this occurs, the winding roller 41 winds the enameled wire 17 onto itself. At this time, the unwinding roller 21 has not yet rotated, meaning it has not yet released the enameled wire 17. The length of the enameled wire 17 between the unwinding roller 21 and the winding roller 41 decreases, pulling the push rod 32 and tension wheel 31 downwards. The push rod 32 and the tension wheel exert force on the enameled wire 17. As a buffer, the push rod 32 is subjected to upward sliding friction from the first friction band 333 and the second friction band 343. During the downward movement of the push rod 32 and the tensioning wheel 31, the sliding friction on the push rod 32 remains constant. Therefore, during the downward movement of the push rod 32 and the tensioning wheel 31, the tension received by the enameled wire 17 remains constant and is always less than the ultimate tensile strength of the enameled wire 17. Thus, the enameled wire 17 will not break during the downward movement of the push rod 32 and the tensioning wheel 31. When the push rod 32 moves downward, it drives the rack 10 to move downward as well, causing the gear 11 and the electronic throttle 12 to rotate at a certain angle. The electronic throttle 12 controls the motor of the third drive source 22 to rotate, driving the pay-off roller 21 to rotate and pay off the enameled wire 17. The greater the downward distance of the push rod 32, the greater the rotation angle of the electronic throttle 12, and the more enameled wire 17 is paid off by the pay-off roller 21. When the amount of enameled wire 17 paid off by the pay-off roller 21 exceeds the amount of enameled wire 17 wound by the winding roller 41, the push rod 32 and the tension wheel 31 move upward, keeping the enameled wire 17 always taut. When the push rod 32 moves upward, the rotation angle of the electronic throttle 12 decreases, reducing the amount of enameled wire 17 paid off by the pay-off roller 21. This process is repeated to dynamically adjust the enameled wire 17. The buffer stroke of the push rod 32 is determined by the length of the push rod 32. Increasing the length of the push rod 32 increases the buffer stroke of the push rod 32.

[0044] 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.
