Description

Technical Field

[0001] The invention relates to the technical field of motor rotor winding equipment, and in particular to an automatic winding machine and a winding method. Background Art

[0002] The coil winding process is an important step in motor manufacturing, especially in the coil winding of linear motors. The arrangement and number of turns of the coil will directly affect the output efficiency of the linear motor. At present, the winding of the rotor coil mainly depends on the staff to start the winding machine to wind the enameled wire into the mold according to the predetermined winding form (such as multi-layer winding or single-layer winding), and then perform high-temperature shaping, curing and drying of the winding.

[0003] However, in practical applications, most of the above processes require manual intervention. For example, the winding machine is prone to rewinding due to wiring errors, and the winding jig and shaping jig need to be adjusted according to the current coil model. Based on this, the Chinese invention patent document (CN112680894A) discloses a coreless bottom line winding and shaping automatic integrated machine and method, which integrates the winding machine and shaping equipment to improve production efficiency.

[0004] However, it is mainly used in the coreless bottom line winding process, which is substantially different from the above-mentioned processing procedures. For example, in the shaping step, the shaping in the invention patent document (CN112680894A) is mainly carried out by pressing and shaping the upper and lower dies which are relatively arranged, and high-temperature shaping operations cannot be performed; such as the wire arrangement step, the patent document (CN112680894A) is mainly applicable to the winding of coreless bottom line winding, etc.; in other words, there is still a lack of automatic winding linear motor coil equipment that integrates winding and shaping. Summary of the invention

[0005] The invention provides an automatic winding machine and a winding method to solve the problem that the prior art lacks winding equipment integrating winding and shaping.

[0006] In order to solve the above technical problems, the technical solution adopted by the present invention is to provide an automatic winding machine, which includes: a frame, a rotating shaft, a wire arrangement module and a shaping module.

[0007] The frame is provided with a wire making area and a wire feeding module, the wire feeding module is located on one side of the frame and is used to pass the wire to be wound; the rotating shaft passes through the wire making area along a first direction, and is arranged to be a winding spindle and a core pulling spindle at intervals, wherein the core pulling spindle is connected to a winding mold that can rotate synchronously with the winding spindle and the core pulling spindle along the first direction toward one side of the winding spindle.

[0008] The cable arrangement module is located at one side of the wire making area along the first direction, and includes a wire nozzle and a moving mechanism for driving the wire nozzle to move along the first direction, wherein the wire can be passed through the wire nozzle along the wire entry module and wound around the winding mold.

[0009] The shaping module comprises a shaping fixture opposite to the wiring module along the first direction and an electrical connection element located in the wire making area, wherein the electrical connection element can be connected to the wire located in the winding mold to form an electrical circuit.

[0010] The technical solution provided by the present invention has the following beneficial effects compared with the prior art: By separately setting up the wire feeding module, wire arranging module and shaping module that cooperate with each other, the integrated operation of winding and shaping is realized. Among them, the moving mechanism of the wire arranging module drives the moving speed of the wire nozzle to match the rotation speed of the rotating spindle, thereby avoiding the problem of wire arranging errors. Compared with the current manual drive wire arranging method, it can effectively reduce the need for manual supervision and the phenomenon of wire withdrawal and re-arrangement.

[0011] In addition, the coordination between the shaping fixture and the power connection element enables electric heating to be achieved by utilizing the characteristics of the wound wire, thereby replacing the current high-temperature baking process.

[0015] By adopting the above technical solution, the elastic part can apply an elastic force to the tensioning wheel through the tensioning seat. When the wire is passed through the tensioning wheel in a certain order, the wire applies a reaction force to the tensioning wheel. When the reaction force is large, the elastic part can be compressed until the elastic force is equal to the reaction force, thereby ensuring that the tension of the wire is always in an appropriate state, allowing the wire to maintain a stable tension during the winding process, avoiding coil quality problems caused by uneven tension.

[0019] The above technical solution is used to quickly and accurately shape the wound coil (conductor), wherein the shaping step is performed simultaneously with the electric heating step, further improving the shape accuracy and consistency of the coil. Compared with the current jigs that need to be adapted according to the wire specifications, the above shaping jigs and winding molds have stronger versatility and can adapt to wires of various wire types, thereby reducing the jig replacement process, eliminating the need to disassemble and assemble the shaping jig, etc., further saving manpower.

[0021] By adopting the above technical solution, the shearing piece and the wire fixing piece can be driven by the same driving mechanism to sequentially perform the above automatic shearing and fixing steps, so as to effectively utilize energy and ensure the degree of automation of the coil winding process.

[0022] In some embodiments, the power connection element is provided with a power connection terminal extending along the second direction, the power connection terminal is connected to the power supply and is in a power-on state, wherein the power connection terminal is protruding from the power connection element and can be electrically connected to the wire located between the shearing piece and the wire fixing piece.

[0023] By adopting the above technical solution, the wound coil is quickly heated, and the coil reaches the required temperature in a short time through the formation of an energized loop, which effectively utilizes the characteristics of the coil itself and improves the shaping efficiency.

The above technical solution is adopted to realize automatic export of the coils that have been wound and shaped, further reducing manual intervention and improving production efficiency and the yield rate of the coils.

[0026] In some embodiments, the present application also provides a winding method, which is applied to the above-mentioned automatic winding machine, comprising: The wires are sequentially passed through the tensioning adjustment assembly to the wire nozzle; the moving mechanism of the wire arrangement module drives the wire nozzle to move along the first direction according to preset parameters, and enables the wire fixing member to fix the starting end of the wire.

DETAILED DESCRIPTION

[0031] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0032] In order to facilitate the subsequent description, before describing the specific structure of the automatic winding machine, this application first combines Figure 1A first direction (X), a second direction (Z), and a third direction (Y) are defined. The first direction is the length direction of the automatic winding machine when it is placed normally, such as the X direction; the second direction is the height direction of the automatic winding machine when it is placed normally, such as the Z direction; and the third direction is the width direction of the automatic winding machine when it is placed normally, such as the Y direction. In this application, the first direction (X), the second direction (Z), and the third direction (Y) are perpendicular to each other.

[0033] It can be understood that the mutual perpendicularity in the present application is not absolute perpendicularity, and the approximate perpendicularity caused by processing errors and assembly errors (for example, the angle between two structural features is 89.9°) is also within the range of mutual perpendicularity in the present application.

[0034] See also Figures 1 to 3 As shown, Figure 1 The schematic diagram of the partial three-dimensional structure of an embodiment of an automatic winding machine provided by the present application is shown in FIG. Figure 1 ; Figure 2 A three-dimensional structural schematic diagram of an embodiment of an automatic winding machine provided by the present application is shown; Figure 3 The schematic diagram of the partial three-dimensional structure of an embodiment of an automatic winding machine provided by the present application is shown in FIG. Figure 2 .

[0035] In some embodiments, the automatic winding machine includes: a frame 10, a rotating shaft 20, a wire arrangement module 30 and a shaping module 40.

[0036] The frame 10 is provided with a wire making area 11 and a wire entry module 12, the wire entry module 12 is located on one side of the frame 10 and is used to pass the wire to be wound; the rotating shaft 20 passes through the wire making area 11 along a first direction, and is arranged to be a winding spindle 21 and a core pulling spindle 22 at intervals, wherein the core pulling spindle 22 is connected to a winding mold 23 that can rotate synchronously with the winding spindle 21 and the core pulling spindle 22 along the first direction toward one side of the winding spindle 21.

[0037] The wire arrangement module 30 is located at one side of the wire making area 11 along the first direction, and includes a wire nozzle 31 and a moving mechanism 32 for driving the wire nozzle 31 to move along the first direction, wherein the wire can be passed through the wire nozzle 31 along the wire entry module 12 and wound around the winding mold 23.

[0038] The shaping module 40 includes a shaping fixture 41 opposite to the wiring module 30 along a first direction and a power connection element 42 located in the wire making area 11 , wherein the power connection element 42 can be connected to the wire located in the winding mold 23 to form a power circuit.

[0039] In the embodiment of the present application, by respectively providing the wire entry module 12, the wire arrangement module 30 and the shaping module 40 which cooperate with each other, the integrated operation of winding and shaping is realized. Figure 2As shown, the wire (such as copper wire) is connected to the wire arrangement module 30 along the wire entry module 12, and the wire nozzle 31 is driven to move by the moving mechanism 32 of the wire arrangement module 30 to realize automatic wire arrangement, wherein the moving speed of the wire nozzle 31 matches the rotation speed of the rotating spindle, thereby avoiding the problem of wire arrangement errors. Compared with the current manual drive wire arrangement method, it can effectively reduce the need for manual supervision and the phenomenon of wire withdrawal and rearrangement. Exemplarily, the wire nozzle 31 is driven by an independent cylinder to move vertically, and the moving mechanism 32 is driven by an independent cylinder to drive the wire nozzle 31 to move horizontally.

[0040] In addition, combined Figure 3 As shown, the cooperation between the shaping fixture 41 and the power connection element 42 enables the electric heating to be realized by utilizing the characteristics of the wound wire, thereby replacing the current high-temperature baking process, greatly saving the manufacturing time of the coil, reducing manual intervention, and allowing the same staff to simultaneously operate multiple devices for synchronous operation, effectively improving the production efficiency and quality of the coil. Exemplarily, the power connection element 42 is connected to one pole of the power supply, and the other pole of the power supply is connected to the device, so that when the power connection element 42 is connected to the wire (such as a copper wire), conduction can be achieved.

[0041] See also Figures 4 to 5 As shown, Figure 4 A schematic diagram of the three-dimensional structure of a wire arrangement module 30 of an automatic wire winding machine provided by the present application is shown; Figure 5 The schematic diagram of the partial three-dimensional structure of an embodiment of an automatic winding machine provided by the present application is shown in FIG. Figure 3 .

[0042] In some embodiments, the moving mechanism 32 also includes a first sensing slot 320 and a first extension plate 321 extending along a first direction, the first sensing slot 320 extending along the first direction and having first sensing elements 322 and second sensing elements 323 spaced apart therefrom, wherein the first extension plate 321 moves synchronously with the wire nozzle 31 and is capable of passing through the first sensing element 322 and the second sensing element 323 in sequence.

[0043] In the embodiment of the present application, two magnetic induction components, the first induction element 322 and the second induction element 323, are provided to accurately control the displacement of the wire nozzle 31, ensure the neatness and consistency of the coil arrangement, and further improve the winding quality of the coil. Exemplarily, there is a groove between the first induction element 322 and the second induction element 323, so that when the first extension plate 321 passes through the first induction element 322 or the second induction element 323, the moving distance or moving speed of the first extension plate 321 can be detected. And wirelessly transmit to the controller or other control unit, so that it is convenient for the staff to monitor the wiring status in time. In some application scenarios, the frame 10 is also provided with a display 70 to visualize the wirelessly transmitted data, so as to facilitate the staff to observe the current processing status.

[0044] In some application scenarios, combined with Figure 5 As shown, the core-pulling spindle 22 is also provided with a second sensing slot 220 and a second extension plate 221, as well as a third sensing element 222 and a fourth sensing element 223 correspondingly installed in the second sensing slot 220. When the core-pulling spindle 22 moves along the first direction (such as when performing the action of pulling out the winding mold 23), the moving distance and moving speed of the core-pulling spindle 22 can be monitored in time. Figure 1 As shown, in order to prevent the first sensing element 322, the second sensing element 323, the third sensing element 222 and the fourth sensing element 223 from being disturbed, a cover plate may be provided to cover the outside of the plurality of sensing elements. The present application does not limit the installation positions of the first sensing element 322, the second sensing element 323 in the first sensing slot 320 and the third sensing element 222, the fourth sensing element 223 in the second sensing slot 220, and they may be adaptively modified according to the current setting stroke (such as taking a larger wiring stroke according to the linear size, etc.).

[0045] See also Figure 6 to Figure 7 As shown, Figure 6 A three-dimensional structural schematic diagram of an embodiment of a tension adjustment assembly 120 of an automatic winding machine provided by the present application is shown; Figure 7 A winding diagram of an embodiment of a tension adjustment assembly 120 of an automatic winding machine provided by the present application is shown.

[0046] In some embodiments, the incoming line module 12 includes a tensioning adjustment assembly 120, which is provided with a plurality of winding wheels 121 and an elastic tensioning member 122, wherein the elastic tensioning member 122 is provided with a guide column 1220 and an elastic member 1221 and a tensioning seat 1222 sleeved on the guide column 1220, the tensioning seat 1222 is connected to the elastic member 1221, and is provided with a tensioning wheel 1223 capable of winding a wire.

[0047] In the present application embodiment, combined Figure 6As shown, the elastic member 1221 is generally sleeved on the guide column 1220 in a compressed state and is limited by the limit seats at both ends, so that the elastic member 1221 can apply an elastic force to the tensioning wheel 1223 through the tensioning seat 1222, as shown in FIG. Figure 7 As shown, when the wire is passed through the tensioning wheel 1223 in a certain order, the wire applies an upward reaction force to the tensioning wheel 1223. When the reaction force is large, the elastic member 1221 can be further compressed until the elastic force is equal to the reaction force, thereby ensuring that the tension of the wire is always in an appropriate state, allowing the wire to maintain a stable tension during the winding process, and avoiding coil quality problems caused by uneven tension.

[0048] In some embodiments, in combination Figure 6 As shown, the tensioning adjustment assembly 120 also includes a wire pulling wheel, a magnetic powder brake 124 and a wire rubbing wheel 125, wherein the wire pulling wheel is provided with a wire blocking column 1230, and when the wire is passed through the wire pulling wheel, it is located on the inner side of the wire blocking column 1230, and extends to the wire rubbing wheel 125 and the magnetic powder brake 124 in sequence.

[0049] The magnetic powder brake 124 is a device that uses the magnetic effect of magnetic powder to transmit torque and achieve braking. In the embodiment of the present application, the magnetic powder brake 124 is used to adjust the tension of the wire, and the wire tension can be accurately controlled by adjusting the current of the magnetic powder brake 124, thereby ensuring the stability and reliability of the wire during the transmission process, reducing the wear and deformation of the wire, and further optimizing the transmission process of the wire. Exemplarily, a pulley with a wire blocking column 1230 is used as the wire inlet end of the tension adjustment component 120, which can prevent the wire from coming out without affecting the transmission of the wire.

[0050] Combination Figure 8 As shown, Figure 8 A three-dimensional structural schematic diagram of an embodiment of a shaping fixture 41 of an automatic winding machine provided in the present application is shown.

[0051] In some embodiments, in combination Figure 1 and Figure 8 As shown, the shaping fixture 41 includes a first fixture part 410 and a second fixture part 411 which are connected to each other. The first fixture part 410 is provided with a first driving mechanism 4101, and the first driving mechanism 4101 is used to drive the shaping fixture 41 to move along the first direction; the second fixture part 411 is provided with a second driving part 4110, a driving rod 4111 and a shaping jig 4112, and the second driving part 4110 is used to drive the driving rod 4111 to drive the shaping jig 4112 to engage the winding mold 23.

[0052] In the embodiment of the present application, the second clamp part 411 is used to quickly and accurately shape the coil wound by the wire, wherein the shaping step is performed simultaneously with the electric heating step, further improving the shape accuracy and consistency of the coil. For example, when the winding is completed, the power connection element 42 contacts the end of the wire to form an energized circuit for electric heating, and the driving rod 4111 is bent under the drive of the second driving part 4110, so that the shaping jig 4112 is engaged with the winding mold 23.

[0053] Compared with the current jigs that need to be adapted according to wire specifications, the above-mentioned shaping jig 4112 and winding mold 23 have stronger versatility and can adapt to various wire types, thereby reducing the jig replacement process. There is no need to disassemble and assemble the shaping jig 4112, etc., and the fully automatic processing operation can be performed at a preset time, further saving labor costs.

[0054] In addition, the coil is heated by utilizing the thermal effect generated when electric current passes through the conductor (copper wire), directly converting electrical energy into thermal energy. This has high heating efficiency and can precisely control the heating temperature. Compared with the current high-temperature baking method, it does not require too much baking equipment, which can save working space.

[0055] See also Figures 9 to 11 As shown, Fig. 9 A schematic diagram of a winding structure of an automatic winding machine according to an embodiment of the present application is shown; Fig.10 A partial schematic diagram of an embodiment of a winding spindle 21 of an automatic winding machine provided by the present application is shown. Figure 1 ; Fig.11 A partial schematic diagram of an embodiment of a winding spindle 21 of an automatic winding machine provided by the present application is shown. Figure 2 .

[0056] In some embodiments, the winding spindle 21 is sequentially sleeved with a shearing piece 210 and a wire fixing piece 211 along a first direction; wherein the shearing piece 210 is circumferentially provided with one or more shearing cuts 2101, and the shearing cuts 2101 have a cutter 2102; the wire fixing piece 211 includes a first wire fixing position 2110 and a second wire fixing position 2112, the first wire fixing position 2110 is provided with an inclined groove 2111 for accommodating the starting end of the wire, and the second wire fixing position 2112 is provided with a guide groove 2113, wherein the end of the wire cut by the shearing piece 210 is located between the shearing piece 210 and the wire fixing piece 211.

[0057] In the embodiment of the present application, the cutting piece 210 and the wire fixing piece 211 can be driven by the same driving mechanism to sequentially perform the above-mentioned automatic cutting and fixing steps, so as to effectively utilize energy and ensure the degree of automation of the coil winding process. Exemplarily, the cutting piece 210 is also provided with a plurality of contacts to ensure that there is a sufficient gap between the cutting piece 210 and the wire fixing piece 211 so that the electrical connection element 42 can be connected to the end of the wire fixed by the wire fixing piece 211.

[0058] In some application scenarios, the shearing member 210 and the wire fixing member 211 are driven by the same driving device, such as Figure 1 The shown one may correspond to the driving device of the core pulling spindle 22, wherein the driving device of the winding spindle 21 is located under the driving device of the shearing piece 210 along the second direction, thereby realizing that the winding spindle 21 and the shearing piece 210 and the wire fixing piece 211 wound on the winding spindle 21 are all driven by different driving devices.

[0059] See also Figure 12 to Figure 14 As shown, Fig.12 A front view of an embodiment of an automatic winding machine provided by the present application is shown; Fig.13 for Fig.12 A magnified view of the local structure; Fig.14 A side view of a winding structure of an automatic winding machine provided in the present application is shown.

[0060] In some embodiments, the power connection element 42 is provided with a power connection terminal 420 extending along the second direction, and the power connection terminal 420 is connected to the power supply and is in a power-on state. Figure 5 and Fig.13 As shown, the electrical terminal 420 is protruding from the electrical connection element 42 and can be electrically connected to the wire located between the cutting piece 210 and the wire fixing piece 211 .

[0061] In the embodiment of the present application, the wound coil is quickly heated, and the coil reaches the required temperature in a short time by forming an electric circuit, which effectively utilizes the characteristics of the coil itself and improves the shaping efficiency. In some application scenarios, the protruding design of the power terminal 420 can effectively avoid its connection with other components. For example, Figure 5 As shown, the top and bottom of the power terminal 420 can also be set to be wedge-shaped, so that the wider side contacts the wire, further preventing it from accidentally contacting other components.

[0062] Combination Fig.14 As shown, the power terminal 420 extends along the second direction, so that no matter where the end of the wire is located at the gap between the shearing member 210 and the wire fixing member 211, it can be connected and connected. Exemplarily, the power connection element 42 is also provided with a driving device that enables it to move along the third direction (to move closer to the winding mold 23 or away from the winding mold 23).

[0063] See also Figure 15 to Figure 16 As shown, Fig.15 A top view of an embodiment of an automatic winding machine provided by the present application is shown; Fig.16 A side view of an embodiment of an automatic winding machine provided by the present application is shown.

[0064] In some embodiments, the frame 10 is further provided with a wire take-up lever 50 and a wire take-up driving member 51 for driving the wire take-up lever 50 to move in a third direction, so that the shearing member 210 can shear the wire. In the embodiment of the present application, the wire take-up lever 50 is used to ensure that the end of the wire will not be damaged by the shaping jig 4112 during subsequent shaping.

[0065] In some embodiments, the frame 10 is further provided with an export mechanism 60, which includes a discharge trough 61 and a push-out member 62 connected to the wire making area 11, wherein the discharge trough 61 and the push-out member 62 are arranged relative to each other along a third direction. When the core-pulling spindle 22 pulls out the winding mold 23, the push-out member 62 can be displaced along the third direction, thereby pushing the coil out and sliding it along the discharge trough 61 to the collection device or the next process. Through the cooperation of the push-out member 62 and the discharge trough 61, the coil that has been wound and shaped can be automatically exported, which further reduces manual intervention and improves production efficiency and the yield rate of the coil.

[0066] See also Fig.16 As shown, the discharge chute 61 is arranged at a certain inclination angle with the frame 10 so that the coil can slide out smoothly by gravity. The feed module and the discharge chute 61 are located on opposite sides of the frame 10 along the third direction so that the processing path of the wire is shorter and the wear of the wire during the processing is reduced.

[0067] In some embodiments, the present application also provides a winding method, which is applied to the above-mentioned automatic winding machine, comprising: (1) Pass the wires through the tension adjustment assembly 120 to the wire nozzle 31 in sequence; (2) The moving mechanism 32 of the cable arrangement module 30 drives the wire nozzle 31 to move along the first direction according to the preset parameters, and enables the wire fixing member 211 to fix the starting end of the wire; (3) The rotating shaft 20 drives the winding mold 23 to rotate, wherein when the winding mold 23 rotates one circle clockwise or counterclockwise, the moving mechanism 32 moves a distance corresponding to the wire diameter; (4) After the wire arrangement module 30 has completed winding according to the preset parameters, the wire take-up rod 50 takes out the wire, and the shaping fixture 41 is engaged with the winding mold 23; (5) The power-connecting element 42 is connected to the wire to form a power-on circuit, heating the wire for a first preset time, and the power-connecting element 42 is moved away from the wire to allow the wire to cool for a second preset time, and the shearing member 210 cuts the wire; (6) The core-pulling spindle 22 is pulled away from the winding mold 23, and the ejector 62 pushes the wire to the discharge chute 61.
