Description

Technical Field

[0001] This invention relates to the field of transformer manufacturing technology, and more specifically, to a transformer winding constant tension wire supply device and transformer winding production equipment. Background Technology

[0002] In the production process of transformer windings, if a constant wire tension is applied to the wire during the winding process to ensure the quality of the winding, the resulting winding surface will be smooth and flat, and the winding will be tight and strong.

[0003] In existing technologies, workers typically manually hold the wire and manipulate it to wind it around a rotating winding frame at a relatively constant tension. This requires workers to have a high level of skill and experience. While some more automated production equipment automates the wire release mechanism, the winding and release mechanisms still operate relatively independently. The winding device often struggles to ensure the wire is wound at a constant tension, which can easily lead to inconsistent tension during the winding process and negatively impact the winding quality. Summary of the Invention

[0004] The main objective of this invention is to provide a constant tension wire supply device for transformer windings and transformer winding production equipment to solve the problem of poor winding quality caused by unstable tension during the winding process in the prior art.

[0005] To achieve the above objectives, according to one aspect of the present invention, a transformer winding constant tension wire supply device is provided, comprising: a wire supply mechanism, a constant tension buffer mechanism, wherein the wire of the wire supply mechanism is wound after passing through the constant tension buffer mechanism, and the constant tension buffer mechanism maintains a constant tension of the wire.

[0006] In one embodiment, the constant tension buffer mechanism includes: a slide block; a slide roller, a slidable portion of which is disposed on the slide block; a constant tension drive mechanism, which is connected to the slide roller in a driving manner; a wire passes through the slide roller, and the constant tension drive mechanism is able to maintain a constant tension in the wire through the slide roller.

[0007] In one embodiment, the constant tension drive mechanism includes a first drive motor and a transmission mechanism. The first drive motor is disposed on the slide block, and the first drive motor drives the slide roller to move through the transmission mechanism.

[0008] In one embodiment, the transmission mechanism includes a pull wire wound around the output shaft of the motor, with the free end of the pull wire disposed on the slide roller.

[0009] In one embodiment, the transmission mechanism further includes a guide wheel, which is disposed on the slide block and located on one side of the slide roller, and the pull wire passes through the guide wheel and is disposed on the slide roller.

[0010] In one embodiment, the transformer winding constant tension wire supply device further includes a control mechanism, which is electrically connected to the constant force drive mechanism and the wire supply mechanism. The control mechanism is capable of acquiring the displacement parameters of the slide roller on the slide block and controlling the constant force drive mechanism and the wire supply mechanism according to the displacement parameters.

[0011] In one embodiment, the control mechanism includes a displacement detection mechanism disposed on the slide block and / or the slide roller, and the displacement detection mechanism is capable of acquiring the displacement parameters of the slide roller on the slide block.

[0012] In one embodiment, the wire supply mechanism includes: a spool mounting component for mounting a spool for wire supply; a motor component for driving the spool mounting component to rotate; and a control mechanism electrically connected to the motor component, wherein the control mechanism is capable of controlling the rotational speed of the motor component.

[0013] In one embodiment, the motor component includes: a second drive motor; and a reducer, wherein the second drive motor is connected to the bobbin mounting component via the reducer.

[0014] To achieve the above objectives, according to one aspect of the present invention, a transformer winding production apparatus is provided, characterized in that it includes the above-described transformer winding constant tension wire supply device.

[0015] By applying the technical solution of this invention, the constant tension buffer mechanism can maintain the constant tension of the conductor. The movable arrangement of its sliding roller and slide block allows the sliding roller to move accordingly when the tension changes during the winding process, thereby maintaining the tension to a certain extent. Moreover, the movement direction of the sliding roller is limited to horizontal movement to avoid the sliding roller being affected by other forces (the sliding roller's own weight). At the same time, the first drive motor drives the sliding roller to move. By utilizing the constant torque of the first drive motor, the tension is kept constant during the adjustment of the sliding roller. Meanwhile, the control mechanism can obtain the displacement parameters of the sliding roller and control the rotation speed of the motor component of the wire feeding mechanism to further maintain the constant tension.

[0028] like Figures 1 to 4 As shown, this invention provides a constant tension wire supply device for transformer windings, comprising a wire supply mechanism 1 and a constant tension buffer mechanism 2. The wire from the wire supply mechanism 1 is wound after passing through the constant tension buffer mechanism 2, which maintains a constant tension on the wire. A constant tension is required during the winding process to ensure good winding quality. The constant tension buffer mechanism 2 adjusts the tension of the wire from the wire supply mechanism 1, ensuring that the tension remains constant and thus guaranteeing winding quality.

[0029] like Figure 3As shown, the constant tension buffer mechanism 2 includes a slide block 21, a slide roller 22, and a constant force drive mechanism. The slide roller 22 is slidably mounted on the slide block 21. The constant force drive mechanism is connected to the slide roller 22 in a transmission manner. The wire passes through the slide roller 22, and the constant force drive mechanism can maintain the tension of the wire constant through the slide roller 22. The constant force drive mechanism generates a first force on the slide roller 22 and drives the slide roller 22 to move in a first direction under the action of the first force. The conductor passes through the slide roller 22, and the conductor can generate a second force on the slide roller 22. Under the action of the second force, the slide roller 22 is driven to move in the second direction. The first force provided by the constant force drive mechanism is a constant force. When the tension of the conductor is constant, the resultant force of the first force, the second force, and the limiting force of the slide block 21 on the slide roller 22 is zero. At this time, the slide roller 22 is held at the initial position. When the tension changes, that is, the second force changes, while the first force does not change, causing the resultant force to change. The slide roller 22 will move under the action of the changed resultant force until the slide roller 22 stops moving. At this time, it indicates that the resultant force on the slide roller 22 is zero, thereby achieving the purpose of constant tension. At the same time, the constant force drive mechanism can also perform corresponding control according to the change of the tension of the conductor (second force) to keep the slide roller 22 at the initial position.

[0030] When using the transformer winding constant tension buffer mechanism 2, the wire supplied by the wire supply mechanism 1 passes through the sliding roller 22 and enters the wire winding mechanism for winding. The direction of the wire changes at the sliding roller 22, thereby generating a second force on the sliding roller 22. When the sliding roller 22 is in its initial position, it indicates that the tension corresponding to the wire is its preferred working tension value. The constant force drive mechanism's constant first force on the sliding roller 22 and the second force provided by the wire together keep the sliding roller 22 in its initial position. When the tension on the wire increases, because the first force does not change, the wire exerts a second force on the sliding roller 22. The tension is reduced by forcefully moving the slide roller 22 from its initial position in the second direction until the combined force of the second force exerted on the slide roller 22 by the wire, the first force exerted on the slide roller 22 by the constant force drive mechanism, and the limiting force exerted on the slide roller 22 by the slide block 21 is zero. That is, when the tension of the wire reaches the preferred tension value, the slide roller 22 stops moving, achieving constant tension. Simultaneously, the displacement of the slide roller 22 indicates that the current tension value of the wire is too high. Therefore, the wire supply mechanism 1 accelerates the supply of wire, thereby reducing the current tension value. As the tension gradually decreases, the first force of the constant force drive mechanism becomes greater than the second force of the wire, causing the slide roller 22 to move in the first direction. The slide roller 22 moves and eventually moves to its initial position. Throughout the process, the movement of the slide roller 22 prevents tension changes and achieves constant tension. When the tension on the conductor decreases, because the first force does not change, the first force exerted on the slide roller 22 by the constant force drive mechanism is greater than the second force exerted on the slide roller 22 by the conductor. The slide roller 22 moves in the first direction to tighten the conductor, thereby relatively increasing the tension of the conductor. This continues until the resultant force of the second force exerted on the slide roller 22 by the conductor, the first force exerted on the slide roller 22 by the constant force drive mechanism, and the limiting force exerted on the slide roller 22 by the slide block 21 is zero. At this point, the slide roller 22 stops moving. 2. If the current tension value of the conductor is too small, the conductor mechanism and / or the wire supply mechanism 1, which cooperate with the transformer winding constant tension buffer mechanism 2, will perform corresponding control to increase the current tension value of the conductor. When the tension value increases, the second force of the conductor is greater than the first force of the constant force drive mechanism, causing the slide roller 22 to move in the second direction and eventually move to the initial position. Throughout the process, the movement of the slide roller 22 can avoid tension changes and achieve the purpose of constant tension. Preferably, the constant force drive mechanism outputs a constant torque, which can overcome the problem of inconsistent tension caused by the instability of human operation in the prior art.

[0031] Furthermore, the slide roller 22 slides freely on the slide block 21 in the horizontal direction, that is, the slide roller 22 moves on the horizontal plane during the movement process, so as to avoid the slide roller 22 being subjected to forces in other directions (such as the weight of the slide roller 22) and causing excessive tension fluctuations.

[0032] As an optional implementation, the constant force drive mechanism includes a first drive motor 23 and a transmission mechanism. The first drive motor 23 is mounted on the slide block 21, and the first drive motor 23 drives the slide roller 22 to move through the transmission mechanism. Utilizing the constant output torque of the first drive motor 23, the second force generated by the constant force drive mechanism on the slide roller 22 is ensured to be constant, thereby avoiding tension fluctuations. Preferably, the first drive motor 23 is a servo motor.

[0033] Furthermore, the transmission mechanism includes a pull wire 24, which is wound around the output shaft of the motor, with its free end positioned on the slide roller 22. When the output shaft of the first drive motor 23 rotates, the pull wire 24 winds around the output shaft as it rotates, reducing its effective length and thus pulling the slide roller 22. When the slide roller 22 moves in the second direction, the pull wire 24 is pulled off the output shaft by the slide roller 22, increasing its effective length and thus releasing the slide roller 22. Figure 3 The part where the pull wire 24 connects to the slide roller 22 is not shown in the diagram.

[0034] In one embodiment, the transmission mechanism further includes a guide wheel 25, which is disposed on the slide block 21 and located on one side of the slide roller 22. The pull wire 24 is disposed on the slide roller 22 via the guide wheel 25. The guide wheel 25 reduces the arrangement size of the pull wire 24, and at the same time ensures that the angle between the pulling direction of the pull wire 24 on the slide roller 22 and the desired movement direction of the slide roller 22 is close to zero or equal to zero, so as to avoid the pull wire 24 exerting other forces on the slide roller 22 and affecting the adjustment effect of the slide roller 22.

[0035] As an optional implementation, the slide block is provided with a strip slide rail, and the slide roller is provided with a slide groove adapted to the strip slide rail. The constant force drive mechanism can drive the slide roller to move towards the first end of the strip slide rail (first direction), and the guide wire can drive the slide roller to move towards the second end of the strip slide rail (second direction). Preferably, the strip slide rail is long and horizontal, ensuring that the slide roller moves in the horizontal direction.

[0036] Specifically, the slide block is equipped with a buffer, and the slide roller has a first preset position and a second preset position on the strip rail. When the slide roller is in the first preset position or the slide roller is in the second preset position, the buffer is set to abut against the rail. The buffer is used to buffer the slide roller when it moves to the limit position (first preset position and second preset position) to avoid interference between the slide roller and other structures of the slide block and cause other losses.

[0037] As an optional implementation, the transformer winding constant tension wire supply device also includes a control mechanism. The control mechanism is electrically connected to the constant force drive mechanism and can acquire the displacement parameters of the slide roller 22 on the slide block 21. Based on these displacement parameters, the control mechanism controls the wire supply mechanism 1. The displacement parameters can be obtained by directly measuring the movement distance of the slide roller 22, or by measuring the winding length of the pull wire 24 corresponding to the number of rotations of the output shaft of the first drive motor 23. When the slide roller 22 moves, the control mechanism acquires the displacement parameters, determines the current tension of the wire from these parameters, and controls the wire supply speed of the wire supply mechanism 1 based on the tension. When the second force on the slide roller 22 increases, it indicates that the winding tension is too high, requiring the wire supply mechanism 1 to increase its wire supply speed. To reduce the tension of the conductor, the torque of the first drive motor 23 remains constant, keeping the first force constant. As the feeding speed of the wire supply mechanism 1 gradually increases, the second force gradually decreases, and the slide roller 22 gradually moves back to its initial position. Throughout the movement of the slide roller 22, the tension of the conductor remains constant. Conversely, when the second force on the slide roller 22 decreases, it indicates that the tension of the winding is too small, and the wire supply mechanism 1 needs to slow down the feeding speed to increase the tension of the conductor. At the same time, the torque of the first drive motor 23 remains constant, keeping the first force constant. As the feeding speed of the wire supply mechanism 1 gradually decreases, the second force gradually increases, and the slide roller 22 gradually moves back to its initial position. Throughout the movement of the slide roller 22, the tension of the conductor remains constant.

[0038] The control mechanism includes a displacement detection mechanism, which is set on the slide block 21 and / or the slide roller 22. The displacement detection mechanism can obtain the displacement parameters of the slide roller 22 on the slide block 21. The displacement detection mechanism can obtain the position of the slide roller 22 in real time through infrared or laser and compare and judge it, and finally obtain the displacement parameters of the slide roller 22.

[0039] As an optional implementation, the wire feeding mechanism 1 includes a spool mounting component 11 and a motor component 12. The spool mounting component 11 is used to mount the spool for wire feeding. The motor component 12 is drivenly connected to the spool mounting component 11 and is used to drive the spool mounting component 11 to rotate. The control mechanism is electrically connected to the motor component 12 and can control the rotational speed of the motor component 12. When the wire feeding mechanism 1 needs to increase the wire feeding speed, the control mechanism controls the rotational speed of the motor component 12 to increase. When the wire feeding mechanism 1 needs to decrease the wire feeding speed, the control mechanism controls the rotational speed of the motor component 12 to decrease.

[0040] The motor component includes a second drive motor 121 and a reducer 122. The second drive motor 121 is connected to the bobbin mounting component 11 through the reducer 122. The reducer 122 is used to adjust the mounting direction of the second drive motor 121 from the axial direction to the vertical axial direction, thereby reducing the space occupied by the second drive motor 121. At the same time, it can cooperate with the second drive motor 121 to meet digital control and ensure positioning accuracy.

[0041] like Figure 4 As shown, the bobbin mounting component 11 also includes a support shaft 111 and an adjustment mechanism. The bobbin is detachably sleeved on the outer periphery of the support shaft 111. The adjustment mechanism is located inside the support shaft and can adjust the diameter of the support shaft 111. When installing the bobbin, the adjustment mechanism does not adjust the diameter of the support shaft 111. Then, the bobbin is sleeved on the outer periphery of the support shaft 111, and the adjustment mechanism adjusts the diameter of the support shaft 111, so that the support shaft 111 and the bobbin are relatively squeezed, thereby increasing the friction between the bobbin and the support shaft 111, and achieving the purpose of relatively fixed setting of the bobbin and the support shaft 111. Preferably, the support shaft 111 is made of a deformable material.

[0042] Optionally, the adjustment mechanism further includes a drive screw 112, a friction block 113, and a slider 114. The drive screw 112 is located inside the support shaft 111, and there is a gap between the drive screw 112 and the support shaft 111. The friction block 113 is fixedly disposed on the inner surface of the support shaft 111. The slider 114 is slidably disposed within the gap, and the slider 114 cooperates with the corresponding friction block 113 to adjust the diameter of the support shaft 112. The drive screw 112 can adjust the position of the slider 114 within the gap to adjust the thickness of the slider 114 and the friction block 113 after they are engaged. The position of the slider 114 is adjusted under the drive of the drive screw 112, thereby adjusting the degree of engagement between 114 and the friction block 113. Then, the diameter of the support shaft 111 is adjusted by the deformation of the support shaft 111.

[0043] Preferably, the cross-sections of the friction block 113 and the slider 114 are both triangular. When the slider 114 slides relative to the corresponding friction block 113, the hypotenuse of the triangle of the slider 114 engages with the hypotenuse of the triangle of the friction block 113. By the relative sliding between the inclined surfaces, the thickness of the slider 114 and the friction block 113 after engagement can be adjusted, thereby achieving the purpose of adjusting the diameter of the support shaft 111.

[0044] The drive screw 112 is provided with an external thread, and the slider 114 is provided with a thread structure that matches the external thread. The slider moves within the gap under the cooperation of the external thread and the thread structure.

[0045] It should be noted that the external thread of the drive screw 112 includes a first thread section and a second thread section. The helical direction of the first thread section is opposite to that of the second thread section. When the drive screw 112 rotates, the slider 114 cooperating with the first thread section and the slider 114 cooperating with the second thread section move in opposite directions. This satisfies the requirement that the drive screw rotates in a single direction, causing multiple sliders to move in different directions. This avoids the situation where the entire support shaft or adjustment mechanism cannot achieve the purpose of adjusting the diameter due to the sliders all moving in the same direction.

[0046] More preferably, the size of the adjustment mechanism is larger than the size of the bobbin in the axial direction of the support shaft 111, or the adjustment position of the adjustment mechanism corresponds to the end face position of the bobbin, thereby ensuring that the friction force of the support shaft 111 on the bobbin is sufficient. In particular, when the slider 114 and the friction block 113 cooperate at the position corresponding to the end face of the bobbin, the deformation generated by the support shaft 111 can also generate a thrust towards the center of the bobbin, further ensuring the fixed reliability of the bobbin.

[0047] To achieve the above objectives, according to one aspect of the present invention, a transformer winding production apparatus is provided, characterized in that it includes the above-described transformer winding constant tension wire supply device.
