DETAILED DESCRIPTION
[0022] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by a person skilled in the art without creative labor fall within the protection scope of the present application.
[0023] Coils, as a basic and important electromagnetic element, have been widely used in modern technology and daily life. Especially the coils with thin wire diameter, due to their small size, high inductive performance and good adaptability to high-frequency signals, play an important role in many key fields, such as superconducting proportional devices, nuclear magnetic resonance equipment, precision sensors, micro-motors, high-frequency or microwave frequency circuits, new energy and aerospace high-precision equipment, etc.
[0024] The performance of the coil is closely related to the winding process, and the diameter, spacing and arrangement density of the coil will affect its performance. The existing winding machine is usually matched with a tensioner, and the applicable wire diameter is usually 0.2mm~2.0mm, while the applicability of wire diameter of 0.1mm and below is poor, the tension cannot be accurately controlled, the wound coil may have crossing or loose phenomenon, and the diameter of the coil cannot be guaranteed to be uniform. And the tensioner has a delay when paying off, and when the speed is fast or the tensile strength of the wire is low, there is a risk of breaking the wire.
[0025] In view of this, please refer to Figure 1 The present application provides a wire paying-off device to overcome at least one of the above technical problems.
[0026] The wire releasing device comprises a wire releasing mechanism 1, a wire transmission mechanism 2, a displacement monitoring mechanism 3 and a control mechanism 4. The wire releasing mechanism 1 is used for releasing the wire 5, the wire transmission mechanism 2 comprises a tension control assembly 21, the wire 5 is wound around the tension control assembly 21, the tension control assembly 21 applies tension to the wire 5 by using its own gravity, the displacement monitoring mechanism 3 is used for monitoring the current height of the tension control assembly 21, and the control mechanism 4 is configured to adjust the speed of the wire releasing mechanism 1 for releasing the wire 5 based on the current height.
[0027] The wire releasing device of the embodiment of the application winds the wire 5 around the tension control assembly 21, the tension control assembly 21 applies tension to the wire 5 by using its own gravity, the current height of the tension control assembly 21 is monitored by using the displacement monitoring mechanism 3, so as to determine whether the tension on the wire 5 is within the preset range. The control mechanism 4 is configured to adjust the speed of the wire releasing mechanism 1 for releasing the wire 5 based on the current height, so as to adjust the tension on the wire 5, so that the tension is within the preset range, and the diameter of the coil is uniform. The application determines the tension on the wire 5 by monitoring the current height of the tension control assembly 21, in the case of selecting a tension control assembly 21 with appropriate mass, the tension range on the wire 5 is reasonable, the applicability to the wire with a wire diameter of 0.1 mm and below is good, and the wire releasing device can also be used for the wire with a wire diameter of 0.2 mm to 2.0 mm and above, and has more extensive applicability.
[0028] Specifically, a reference height can be set in advance, the current height is compared with the reference height, if the current height is higher than the reference height, it indicates that the tension on the wire 5 is large at this time, the tension on the wire 5 can be reduced by increasing the speed of the wire releasing mechanism 1, which is reflected on the wire releasing device as the current height is reduced. Conversely, if the current height is less than the reference height, it indicates that the tension on the wire 5 is small at this time, the tension on the wire 5 can be increased by reducing the speed of the wire releasing mechanism 1, which is reflected on the wire releasing device as the current height is increased. By controlling the current height to tend to the reference height, the tension on the wire 5 can tend to the preset range, that is, the tension on the wire 5 is stable. The change of the tension on the wire 5 is reflected in the change of the current height of the tension control assembly 21 in real time, the tension on the wire 5 can be directly judged by the current height whether it is within the preset range, the speed of the wire releasing mechanism 1 for releasing the wire 5 can be adjusted in real time by the control mechanism 4, which is more sensitive and accurate than the prior art.
[0029] Please refer to Figure 1In some embodiments, the tension control assembly 21 comprises at least one movable pulley, and the wire 5 is wound around the movable pulley. The movable pulley can reduce the friction between the wire 5 and the tension control assembly 21, preventing the tension on the wire 5 from being affected. If only one movable pulley is provided, the movable pulley is arranged on the upper side of the horizontally arranged wire 5. At this time, the tension on the wire 5 needs to bear a relatively large gravity of the movable pulley, and a movable pulley with a small mass needs to be selected.
[0030] Referring to Figure 1 In some embodiments, the wire transmission mechanism 2 further comprises a gantry 22 and at least one fixed pulley, and the fixed pulley is rotatably connected to the gantry 22, and the wire 5 is wound around the fixed pulley. By arranging the fixed pulley and the movable pulley to form a pulley block, a suitable combination can be selected according to the needs, so that the gravity of the tension control assembly 21 can be distributed to the wire 5, preventing the tension on the wire 5 from being too large to exceed the preset tension range of the wire 5.
[0031] Referring to Figure 1 In some embodiments, the movable pulley has an axis of rotation 23, and the tension control assembly 21 further comprises a weight 211 connected to the axis of rotation 23 of the movable pulley, and the displacement monitoring mechanism 3 is used to monitor the current height of the weight 211. On the one hand, a weight 211 with a suitable mass can be selected to adjust the weight of the tension control assembly 21, and on the other hand, the displacement of the position of the weight 211 in the horizontal direction is small and can be ignored. By taking the current height of the weight 211 as the monitoring object, the monitoring of the current height can be more accurate.
[0032] Referring to Figure 1 In some embodiments, the wire transmission mechanism 2 further comprises a guide rod 24 and a guide pulley 25, the guide rod 24 is provided with a plurality of connecting holes 241, the guide rod 24 is connected to the gantry 22, and the axis of rotation 23 of the guide pulley 25 is detachably arranged in one of the connecting holes 241.

Among them, the diameter of the third fixed pulley 28 is greater than the diameter of the first fixed pulley 26 and the second fixed pulley 27, so as to avoid the intersection of the guide wire 5. The heavy hammer 211 is hung below the movable pulley group through the wire rope, and the gravity of the heavy hammer 211 acts on the movable pulley group and the guide wire 5, so as to realize the automatic straightening of the guide wire 5. Different weights of the heavy hammer 211 can be selected according to the actual diameter, friction coefficient and tensile strength of the guide wire 5, so as to adjust the tension applied to the guide wire 5 and avoid excessive or insufficient tension.

[0038] Referring to Figure 1 In some embodiments, the displacement monitoring mechanism 3 comprises a displacement sensor 31, which can be an ultrasonic sensor or a laser displacement sensor 31, and the displacement sensor 31 is arranged below the tension control assembly 21 along the direction of gravity.

[0040] The pay-off device further comprises a sliding platform 8, and the pay-off mechanism 1, the wire transmission mechanism 2 and the displacement monitoring mechanism 3 are connected to the sliding platform 8 to fix the relative positions of the pay-off mechanism 1, the wire transmission mechanism 2 and the displacement monitoring mechanism 3. The moving end of the linear transmission mechanism 6 is connected to the sliding platform 8, so that the pay-off mechanism 1, the wire transmission mechanism 2 and the displacement monitoring mechanism 3 can make translational motion as a whole, which is convenient for winding. The wire winding mechanism 7 comprises a wire winding motor 71 and a wire winding shaft 72, and the wire winding shaft 72 is drivingly connected to the output end of the wire winding motor 71. The wire winding motor 71 drives the wire winding shaft 72 to rotate, and the wire winding shaft 72 is used for winding the wire 5 to form a coil. In other embodiments, different wire winding mechanisms 7 can be selected according to the shape and size of the target coil.
[0041] The motion parameters of the sliding platform 8 are set according to the required parameters of the coil, and the sliding platform 8 is driven by the linear transmission mechanism 6 to make translational motion, so that the wire 5 can be stably wound into a coil along the preset parameters during the winding of the coil. The current height of the tension control assembly 21 in the pay-off mechanism 1 is monitored by the displacement monitoring mechanism 3, compared with the preset height, and the speed of the pay-off mechanism 1 releasing the wire 5 is controlled by the control mechanism 4, so as to adjust the tension on the wire 5, so that the tension is within the preset range, and the diameter of the coil is uniform.
[0042] Referring to Figure 6In some embodiments, the linear transmission mechanism 6 comprises a translation motor 61, a speed reducer 62 and a screw-nut pair 63, the translation motor 61 is drivingly connected to the input end of the speed reducer 62, the output end of the speed reducer 62 is drivingly connected to a screw 64 in the screw-nut pair 63, and a nut 65 in the screw-nut pair 63 is drivingly connected to the sliding platform 8, so that the translation movement of the sliding platform 8 is stable and reliable.
[0043] Referring to Figure 6 Optionally, a motor base plate 66 is arranged below the translation motor 61 and the speed reducer, and a slide rod base plate 67 is arranged below the screw-nut pair 63, and the height of the motor base plate 66 and the slide rod base plate 67 is designed to ensure that the translation motor 61, the speed reducer and the screw-nut pair 63 are coaxial.
[0044] Referring to Figure 6 Optionally, the translation motor 61 is fixed on the bottom base 9 by a translation motor snap ring 68, the speed reducer is fixed on the bottom base 9 by a speed reducer snap ring 69, and the screw-nut pair 63 is fixed on the bottom base 9 by the slide rod base plate 67. The control mechanism 4 is the control system and operation center of the present application, and can control and set parameters of the start-stop, rotation speed and rotation direction of the pay-off motor 11, the translation motor 61 and the winding motor 71, can receive signals transmitted by the displacement monitoring mechanism 3 and accurately control the rotation speed of the pay-off motor 11 through feedback control, and can also have a display function. The bottom base 9 provides a basic installation platform of the present embodiment, and realizes the integration of all components on the bottom base, facilitating transportation and installation.
[0045] According to a third aspect of the present application, a pay-off method is provided for the pay-off system as described above, the control mechanism 4 controls the pay-off device to pay off the wire 5, controls the linear transmission mechanism 6 to move linearly, and controls the winding mechanism 7 to rotate and wind the wire 5. The control mechanism 4 compares the current height of the tension control assembly 21 with the preset height, if the current height is greater than the preset height, the speed of the pay-off mechanism 1 releasing the wire 5 is increased, and if the current height is less than the preset height, the speed of the pay-off mechanism 1 releasing the wire 5 is decreased.
[0046] Specifically, the displacement monitoring mechanism 3 continuously sends the current height signal of the tension control assembly 21 to the control mechanism 4. When the current height is lower than the preset height, it indicates that the unwinding speed is greater than the winding speed, that is, the tension on the wire 5 is less than the preset range, at this time the unwinding motor 11 starts to slow down until the current height reaches the preset height. Conversely, when the current height is higher than the preset height, it indicates that the unwinding speed is less than the winding speed, that is, the tension on the wire 5 is greater than the preset range, at this time the unwinding motor 11 starts to speed up until the current height reaches the preset height. Alternatively, the speed of the unwinding motor 11 is controlled by a proportional-integral-derivative (PID) control equation. There will be errors in this process, and the actual balance position of the tension control assembly 21 is the preset height interval considering the error. By adjusting the parameters of the PID control equation, the error and the unwinding acceleration are small, the tension on the wire 5 is relatively stable, and the unwinding speed is close to uniform speed. In this way, it can avoid breaking the wire 5 due to too large tension, and can also avoid the phenomenon of loose or crossed arrangement of the wire 5 due to too small or too large tension. In terms of translation wire feeding, by calculating the rotation speed of the winding mechanism 7, the rotation speed of the translation motor 61 and the translation speed of the linear transmission mechanism 6, the parameters can be preset to ensure that when the winding mechanism 7 completes one winding, the linear transmission mechanism 6 drives the sliding platform 8 to translate a distance of one wire diameter, thereby realizing dynamic and accurate wire feeding in the horizontal direction.
[0047] Through unwinding feedback control and matching of translation wire feeding speed, near-uniform-speed automatic and accurate wire feeding can be realized, the risk of breaking the wire 5 is reduced, the quality of coil forming is improved, and the wire diameter of the wire 5 is not limited, which can be used for automatic unwinding of relatively thick wire diameter and automatic unwinding of relatively thin wire diameter. In addition, by combining the pulley group and the displacement sensor 31, the traditional servo tension meter in the traditional unwinding device is replaced, and the economic cost is reduced.
