DETAILED DESCRIPTION

[0024] This application is based on the inventor's discovery and understanding of the following facts and problems:

[0025] The winding device in the related art can only perform the simplest winding work. After the coiled coil is removed from the winding drum, the coils are easily entangled with each other, which has a great impact on the wire embedding work. Especially for the winding using Litz wire, due to the large number of turns of Litz wire, its wire diameter is thicker and its plastic deformation is poor, the Litz wire coil is easy to deform over time after being removed from the winding drum, making the winding forming and wire embedding more difficult.

[0026] In addition, due to the large number of turns of Litz wire, its wire diameter is thicker, its plastic deformation is poor, and the winding formation is difficult, resulting in its scattered arrangement in the slot and low slot filling rate. If it is wound by threading, the winding efficiency is low.

[0027] Embodiments of the present invention are described in detail below, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and cannot be understood as limiting the present invention.

In addition, features defined as "first" and "second" may explicitly or implicitly include one or more of the features. In the description of the present invention, unless otherwise specified, "multiple" means two or more.

[0029] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0030] The coil winding molding apparatus 1 according to an embodiment of the present invention will be described below with reference to the accompanying drawings.

[0031] like Figure 1-Figure 4As shown, the coil winding forming device 1 according to the embodiment of the present invention includes a stand 10, a wire 20, a winding plate 30, a rotation driving device 40 and a heating device 50.

[0032] The wire 20 is coated with a thermosetting adhesive. The winding plate 30 is rotatably arranged on the stand 10, and the wire 20 is suitable for being wound on the winding plate 30 by the rotation of the winding plate 30. The rotation drive device 40 is arranged on the stand 10 and is transmission-connected with the winding plate 30. The heating device 50 is suitable for heating the winding plate 30.

[0033] Specifically, first, one end of the wire 20 is fixed on the winding plate 30, and then the rotation drive device 40 is controlled to drive the winding plate 30 to rotate. The wire 20 is gradually wound on the winding plate 30 during the rotation of the winding plate 30 until the winding of the required coil winding is completed. Then, the heating device 50 is controlled to heat the winding plate 30 and the wire 20 on the winding plate 30. The thermosetting adhesive on the wire 20 is cured after being heated, so that the wire 20 is shaped. Finally, the wound wire 20 is removed from the winding plate 30 to complete the forming of the coil winding.

[0034] According to the coil winding forming equipment 1 of the embodiment of the present invention, by setting the winding plate 30 and the rotating driving device 40, the rotating driving device 40 can be used to drive the winding plate 30 to rotate, so that the wire 20 is gradually wound on the winding plate 30 as the winding plate 30 rotates, eliminating the manual winding process and improving the winding efficiency.

[0035] Furthermore, by coating the wire 20 with a thermosetting adhesive and providing a heating device 50, the wire 20 is heated after winding to solidify the thermosetting adhesive on the wire 20, so that the wire 20 no longer deforms. In this way, even if the wire 20 after winding and shaping is removed from the winding board 30, the wire 20 will not deform again under the curing effect of the curing adhesive. Compared with the winding device in the related art, the problem of the wire being entangled when the wire is removed from the winding board can be avoided, and the deformation of the wire with a thicker wire diameter and poor plastic deformation, such as Litz wire, over time after removal can be avoided, so that the shaping of the wire 20 is more reliable, which is convenient for the subsequent wire embedding work and improves the wire embedding efficiency.

[0036] In addition, by providing a heating device 50, the speed of thermal curing can be accelerated, the time of thermal curing can be shortened, and the winding forming efficiency can be improved. Moreover, the wire 20 can be heated directly on the winding plate 30, which can save the process of removing the wire 20 and then heating it. It can also avoid deformation and entanglement of the wire 20 during the process of removing the wire 20, further ensuring that the wire 20 is reliably formed.

[0037] For Litz coils with more turns, thicker wire diameter and poorer plastic deformation, the winding method of heating and curing after winding is more efficient than the threading method.

[0038] Therefore, the coil winding forming device 1 according to the embodiment of the present invention has the advantages of high forming efficiency and reliable forming.

[0039] The coil winding forming device 1 according to a specific embodiment of the present invention will be described below with reference to the accompanying drawings.

[0040] In some specific embodiments of the present invention, Figure 1-Figure 4 As shown, the coil winding forming device 1 according to the embodiment of the present invention includes a stand 10, a wire 20, a winding plate 30, a rotation driving device 40 and a heating device.

[0041] Specifically, Figure 3 and Figure 4 As shown, the coil winding forming device 1 also includes a cooling device, which is suitable for cooling the winding plate 30. In this way, after the cured adhesive layer of the wire 20 is cured by heat, the cooling device can be used to cool the wire 20, so that the wire 20 can be quickly restored to normal temperature, which is convenient for removing the wire 20 from the winding plate 30. In addition, by providing the cooling device, the cooling time of the wire 20 can be shortened, and the forming time of the wire 20 can be further shortened, thereby improving the forming efficiency of the wire 20.

[0042] Specifically, Figure 3 and Figure 4 As shown, the cooling device includes a cooling water channel 61 and a cooling water valve 62. The cooling water channel 61 is provided in the winding plate 30 and communicates with the cooling water source through the cooling water valve 62. The cooling water channel 61 is arranged in a serpentine shape in the winding plate 30. In this way, when cooling is required, the cooling water valve 62 is opened to allow the cooling water at the cooling water source to flow into the cooling water channel 61. The cooling water in the cooling water channel 61 exchanges heat with the wire 20, thereby reducing the temperature of the wire 20 and cooling the wire 20 quickly.

[0043] Furthermore, if Figure 3 and Figure 4 As shown, the heating device 50 is a heating wire and is arranged in the winding plate 30. The length direction of the heating wire is oriented along the length direction of the winding plate 30. There are two heating wires and they are located on both sides of the cooling water channel 61 in the width direction of the winding plate 30. In this way, the heating wire can be energized to heat the winding plate 30 when heating is required. The two heating wires are located on both sides of the cooling water channel 61 in the width direction of the winding plate 30 to improve heating uniformity and heating efficiency.

[0044] Figure 1-Figure 3 1 shows a coil winding forming device 1 according to some examples of the present invention. Figure 1 and Figure 2As shown, the coil winding forming device 1 also includes an upper pressing plate driving device 71, an upper pressing plate 70, a lower pressing plate driving device 81 and a lower pressing plate 80 (the up and down directions are shown by arrows in the figure, and the horizontal direction is perpendicular to the up and down directions). The upper pressing plate driving device 71 is arranged on the stand 10. The upper pressing plate 70 is transmission-connected to the upper pressing plate 70 driving device and can be raised and lowered between an upper shaping position and an upper avoidance position. When the upper pressing plate 70 is in the upper shaping position and the winding plate 30 is in a horizontal position, the upper pressing plate 70 is suitable for squeezing the upper surface of the wire 20 on the winding plate 30, and the upper pressing plate 70 avoids the winding plate 30 when in the avoidance position. The lower pressing plate driving device 81 is arranged on the stand 10. The lower pressing plate 80 is transmission-connected to the lower pressing plate driving device 81 and can be raised and lowered between the lower shaping position and the lower avoidance position. When the lower pressing plate 80 is in the lower shaping position and the winding plate 30 is in the horizontal position, the lower pressing plate 80 is suitable for squeezing the lower surface of the wire 20 on the winding plate 30, and the lower pressing plate 80 avoids the winding plate 30 when in the avoidance position. It should be understood here that the horizontal position of the winding plate 30 means that its length direction and width direction are both oriented in the horizontal direction, in other words, the thickness direction of the winding plate 30 is oriented in the up-down direction. In this way, before the heating device 50 is heated, the upper and lower surfaces of the wire 20 can be squeezed and shaped by the upper pressing plate 70 and the lower pressing plate 80, so that the arrangement of the wire 20 is more regular and neat, and the full slot rate is improved.

[0045] Advantageously, if Figure 1 and Figure 2 As shown, the coil winding forming device 1 also includes an end pressing plate driving device 91 and an end pressing plate 90. The end pressing plate driving device 91 is arranged on the stand 10. The end pressing plate 90 is connected to the end pressing plate driving device 91 in a transmission manner and can move between a shaping position and an avoidance position. One end of the winding plate 30 in the length direction is connected to the rotating driving device 40 through a turntable 31. When the end pressing plate 90 is in the shaping position and the winding plate 30 is in a horizontal position, the end pressing plate 90 is suitable for jointly squeezing the wire 20 on the winding plate 30 from both ends of the winding plate 30 with the turntable 31. When the end pressing plate 90 is in the avoidance position, the winding plate 30 avoids the winding plate 30. In this way, before the heating device 50 is heated, the end pressing plate 90 and the turntable 31 can be used to extrude and shape the wire 20, so that the arrangement of the wire 20 is more regular and neat, and the full slot rate is improved.

[0046] More advantageously, if Figure 3 As shown, the end pressing plate 90 is provided with an electric contact, which is electrically connected to the power supply, and the winding plate 30 is provided with an electric terminal 51, which is electrically connected to the heating device 50. When the winding plate 30 is in a horizontal position and the end pressing plate 90 is in the shaping position, the electric contact contacts the electric terminal 51 to supply power to the heating device 50. In this way, it is convenient to supply power to the heating device 50, avoid the heating device 50 from being led from the rotating part of the winding plate 30, and reduce the difficulty of power supply.

[0047] Furthermore, if Figure 2 As shown, the end surface of the end pressing plate 90 facing the winding plate is provided with an avoidance groove 92, and the end of the winding plate 30 away from the rotating disk 31 is suitable for fitting in the avoidance groove 92. This makes it easier for the end pressing plate 90 to squeeze the wire 20, thereby improving the extrusion shaping effect of the wire 20.

[0048] Specifically, the end pressing plate 90 is adapted to contact the upper pressing plate 70 at the upper shaping position and the lower pressing plate 80 at the lower shaping position at the shaping position, so as to facilitate the control of the positioning of each pressing plate and further facilitate the comprehensive shaping of the wire 20.

[0049] Specifically, Figure 3 As shown, a plurality of spaced partitions 32 are provided on the winding plate 30, and a bridge plate 33 is connected to each partition 32. Specifically, a winding area can be formed between two adjacent partitions 32, and multiple turns of coils can be wound in each winding area to form a coil group. The coil groups on both sides of each partition 32 can be connected by a bridge section of the wire 20, and the bridge section can extend along the edge of the bridge plate 33. During winding, the winding plate 30 can be driven to rotate first, and after the coil group in one winding area is wound, the winding plate 30 is stopped from rotating, and the wire 20 is guided to extend along the edge of the bridge plate 33, and then the winding plate 30 is driven to rotate to complete the winding of the coil group in the next winding area. In this way, multiple winding areas can be separated by the partition 32, which is convenient for winding the wire to form multiple coil groups, and the bridge plate 33 can facilitate the guidance of the bridge section wire between adjacent coil groups.

[0050] Specifically, the upper pressing plate 70 is suitable for contacting the partition 32 when in the upper shaping position, and the lower pressing plate 80 is suitable for contacting the partition 32 when in the lower shaping position. This can facilitate the control of the upper pressing plate 70 and the lower pressing plate 80 in place, improve the shaping effect of the wire 20, and improve the full slot rate.

[0051] Specifically, the distance between the upper pressing plate 70 at the upper avoidance position and the partition 32 is equal to the distance between the lower pressing plate 80 at the lower avoidance position and the partition 32, and the upper pressing plate driving device 71 and the lower pressing plate driving device 81 can operate synchronously to synchronously drive the upper pressing plate 70 and the lower pressing plate 80. In this way, the upper pressing plate 70 and the lower pressing plate 80 can extrude and shape the wire 20 at the same time.

[0052] Further, the partition 32 is detachably arranged on the winding plate 30. In this way, after the wire 20 is shaped, the wire can be removed from the winding plate 30 together with the partition 32, so that the wire 20 can be removed from the winding plate 30 easily.

[0053] More specifically, Figure 3As shown, the coil winding forming device 1 also includes a wire pressing block 100, a guide rail 102 is provided on the stand 10, a slider 101 is slidably provided on the guide rail 102 along the length direction of the winding plate 30, the wire pressing block 100 is arranged on the slider 101 in a liftable manner, and a wire groove is provided on the lower surface of the wire pressing block 100, and the wire 20 is suitable for fitting in the wire groove. Specifically, before winding, the height of the wire pressing block 100 can be adjusted according to the size of the wire 20, and the wire 20 is kept in a taut state when the wire 20 can slide. In this way, the wire pressing block 100 can be used to position and guide the wire 20, ensuring that the wire 20 remains in a taut state during the winding process, making the winding process more stable and reliable, and making the winding of the wire 20 more regular and neat.

[0054] Furthermore, a self-lubricating material layer is provided on the lower surface of the wire pressing block 100 and the upper surface of the sliding block 101. Specifically, the self-lubricating material layer can be a polytetrafluoroethylene material layer, which can prevent the wire 20 from being scratched.

[0055] Optionally, the conductor 20 is a Litz wire. In this way, the Litz wire with a thicker wire diameter and poorer plastic deformation can be wound, which is convenient for the shaping of the Litz wire and improves the full slot rate. Compared with ordinary enameled wire windings, the Litz wire winding can make the magnetic field distribution of the motor more uniform, thereby improving the motor efficiency.

[0056] Specifically, due to the different slot types of the motor stator, the dimensions of the Litz wire winding are different, and the size and spacing of the partition 32 and the length of the winding plate 30 can be adjusted according to actual needs. For example, the height of the partition 32 above the surface of the winding plate 30 can be equal to one-half of the target motor stator slot width. The spacing of the partition 32 can be equal to the target motor stator slot depth.

[0057] Specifically, the rotation driving device 40 may include a three-phase motor 41 and a reducer 42. The three-phase motor can control the winding plate 30 to rotate clockwise or counterclockwise, and the reducer 42 can adjust the speed of the winding plate 30 to rotate.

[0058] The upper pressing plate driving device 71, the lower pressing plate driving device 81 and the end pressing plate driving device 91 may be cylinders to ensure sufficient squeezing force.

[0059] Reference below Figure 1-Figure 4 The working process of the coil winding forming device 1 according to the embodiment of the present invention is described.

[0060] The outlet end of the Litz wire is fixed on the winding plate 30, and the winding plate 30 is driven to rotate by the rotating drive device 40 to wind the conductor 20 on the winding plate 30. Then the bridge plate 33 is used to lead out the bridge section of the conductor 20, and then the winding is continued, and this is repeated until the winding is completed. The winding plate 30 is rotated to a horizontal position. The upper pressing plate driving device 71 and the lower pressing plate driving device 81 are started synchronously, and the upper pressing plate 70 and the lower pressing plate 80 are pressed synchronously onto the partition 32 and the conductor 20 to perform radial shaping on the conductor 20, and then the end pressing plate driving device 91 is started to press the end pressing plate 90 to contact with the upper pressing plate 70 and the lower pressing plate 80. At this time, the power contact on the end pressing plate 90 contacts the power terminal 51 of the heating device 50 and is energized to heat the conductor 20. When it is heated to a specified temperature and a specified time, the heating device 50 is powered off. Then the cooling water valve 62 is opened to cool the conductor 20. After cooling to room temperature, the end pressing plate 90, the lower pressing plate 80 and the upper pressing plate 70 are driven in sequence to move away from the winding plate 30, and the formed winding is removed to complete the coil winding forming work.
