Description

Technical Field

[0001] The present invention relates to the technical field of core winding machines, and in particular, to a winding device and a winding equipment. Background Art

[0002] The motor core is an important component in a motor. It bears the magnetic field and mechanical force of the motor and has a crucial impact on the performance and efficiency of the motor. The motor core usually adopts a laminated structure, which is composed of multiple thin silicon steel sheets laminated together. Each silicon steel sheet has been specially treated to reduce iron loss and hysteresis loss, thereby improving the efficiency of the motor.

[0003] Currently, for motors, stator core winding and rotor core winding are important links, which are related to the quality of products. For stator and rotor cores with outward-facing slots, a flying fork winding machine is often used for winding. In traditional winding machines, for some cores with too small operating spaces at both ends, the winding machine is prone to being blocked when moving in the radial direction of the core, which will reduce the number of winding turns, resulting in a smaller magnetic field strength and thus affecting the magnetism. Summary of the Invention

[0004] The purpose of the present invention is to provide a winding device to solve the technical problem in the prior art that the winding machine is prone to reduce the number of winding turns and the magnetic field strength due to being blocked when moving on the core, thereby affecting the magnetism.

[0005] To achieve the above purpose, the technical solution adopted by the present invention is: to provide a winding device, including: a frame; an assembly shaft supported on the frame; a die head assembly, including a die head seat connected to the assembly shaft and a positioning seat for abutting against the tooth part of the core to be wound with wire. The positioning seat is elastically connected to the other end of the die head seat opposite to the end connected with the assembly shaft and can move relative to the die head seat in the axial direction of the assembly shaft; a winding assembly, including a winding component for winding the enameled wire on the tooth part of the core to be wound. The winding component is arranged on the periphery of the die head assembly and can rotate relative to the die head assembly with the axis of the assembly shaft as the axis; a wire guiding assembly, including an upper wire guiding ear and a lower wire guiding ear for guiding the enameled wire to the tooth part. The upper wire guiding ear and the lower wire guiding ear are respectively arranged on the die head seat and are spaced apart in the direction perpendicular to the bottom surface of the frame; and a push rod assembly, including a push rod seat movable along the axial direction of the assembly shaft, an upper push rod and a lower push rod respectively connected to the push rod seat, and a push rod seat power component for driving the push rod seat to move. The upper push rod has an upper wire guiding inclined surface for guiding the movement of the enameled wire, and the lower push rod has a lower wire guiding inclined surface for guiding the movement of the enameled wire; the upper wire guiding ear has an upper installation groove located on its bottom surface for the upper push rod to slide; the lower wire guiding ear has a lower installation groove located on its bottom surface for the lower push rod to slide.

[0033] As Figures 1 to 9 shown, the winding device 100 provided in this embodiment includes: a frame 10; a mounting shaft 20 supported on the frame 10; a die head assembly 30 including a die head seat 31 connected to the mounting shaft 20 and a positioning seat 32 for abutting against the tooth portion of the core 200 to be wound with wire, the positioning seat 32 being elastically connected to the other end of the die head seat 31 opposite to the end connected to the mounting shaft 20 and being able to move relative to the die head seat 31 in the axial direction of the mounting shaft 20; a winding assembly 40 including a winding member 41 for winding an enameled wire (not shown in the figure) around the tooth portion of the core 200 to be wound, the winding member 41 being disposed on the periphery of the die head assembly 30 and being able to rotate relative to the die head assembly 30 with the axis of the mounting shaft 20 as the axis; a wire guiding assembly 50 including an upper wire guiding ear 51 and a lower wire guiding ear 52 for guiding the enameled wire to the tooth portion, the upper wire guiding ear 51 and the lower wire guiding ear 52 being respectively disposed on the die head seat 31 and being spaced apart in the direction perpendicular to the bottom surface of the frame 10; and a push rod assembly 70 including a push rod seat 71 movable along the axial direction of the mounting shaft 20, an upper push rod 72 and a lower push rod 73 respectively connected to the push rod seat 71, and a push rod seat power member 74 for driving the push rod seat 71 to move, the upper push rod 72 having an upper wire guiding slope 721 for guiding the movement of the enameled wire, the lower push rod 73 having a lower wire guiding slope 731 for guiding the movement of the enameled wire; the upper wire guiding ear 51 having an upper mounting groove 511 located on its bottom surface for the upper push rod 72 to slide; the lower wire guiding ear 52 having a lower mounting groove 521 located on its bottom surface for the lower push rod 73 to slide.

[0034] The winding device 100 includes a wire assembly 50 and a push rod assembly 70. The wire assembly 50 includes an upper wire support ear 51 and a lower wire support ear 52 for guiding the enameled wire to the tooth portion. The upper wire support ear 51 and the lower wire support ear 52 are respectively arranged on the die head seat 31 and are spaced in a direction perpendicular to the bottom surface of the frame 10. The push rod assembly 70 includes a push rod seat 71 that can move along the axial direction of the assembly shaft 20, an upper push rod 72 and a lower push rod 73 respectively connected to the push rod seat 71, and a push rod seat power member 74 for driving the push rod seat 71 to move. The upper push rod 72 has an upper wire support ear for guiding the enameled wire to move. The lower push rod 73 has a lower wire slope 731 for guiding the movement of the enameled wire; the upper wire support ear 51 has an upper mounting groove 511 located on its bottom surface for the upper push rod 72 to slide, and the lower wire support ear 52 has a lower mounting groove 521 located on its bottom surface for the lower push rod 73 to slide. In this way, for some iron cores 200 with too small operating space at both ends, the upper push rod 72 and the lower push rod 73 of the push rod assembly 70 can be used to guide the enameled wire to the tooth portion of the iron core 200, thereby ensuring that a larger number of enameled coils can be wound in the groove, so that the iron core 200 has a higher magnetic field strength, thereby ensuring the magnetic properties of the motor.

[0035] See also Figures 1 to 9 The winding device 100 provided in this embodiment includes a frame 10, an assembly shaft 20, a die assembly 30, a winding assembly 40, a wire assembly 50 and a push rod assembly 70. The frame 10 can be movably mounted on a base plate 300. The base plate 300 is provided with a frame power member 310 capable of driving the frame 10 to move. The frame power member 310 is, but not limited to, a motor, which is connected to the frame 10 through a screw rod and a nut seat and drives the frame 10 to move on the base plate 300. In this embodiment, the frame 10 includes a first vertical plate 101, a second vertical plate 102 parallel to and spaced from the first vertical plate 101, and a horizontal plate 103 connected to the surface of the second vertical plate 102 on the side away from the first vertical plate 101. The first vertical plate 101, the second vertical plate 102 and the horizontal plate 103 are connected and fixed by screws, welding or any other existing fixing methods.

[0036] See also Figures 1 to 7 , Figure 9 The winding device 100 provided in this embodiment is used to wind the iron core 200, which can be a straight slot iron core or a skewed slot iron core, and is supported on the base plate 300 by an iron core mounting frame (not shown). In this embodiment, the iron core 200 is but not limited to a skewed slot iron core, which includes a core shaft 201, a hook 202 mounted on the core shaft 201, and a core lamination 203.

[0037] See also Figure 2 and Figure 5, the assembly shaft 20 provided in this embodiment is supported on the frame 10. The die head assembly 30 includes a die head seat 31 connected to the assembly shaft 20 and a positioning seat 32 for abutting against the tooth part of the to-be-wound iron core 200. The positioning seat 32 is elastically connected to the other end of the die head seat 31 opposite to the end connected to the assembly shaft 20 and can move relative to the die head seat 31 in the axial direction of the assembly shaft 20. In this embodiment, the assembly shaft 20 is supported on the first vertical plate 101. The die head seat 31 includes a mounting block 311 with a rectangular cross-section and a panel 312. One end of the mounting block 311 is fixedly connected to the assembly shaft 20 by all existing fixing methods such as screws and welding, and the other end is fixedly connected to the panel 312 by all existing fixing methods such as screws and welding. The mounting block 311 has four surfaces located between the assembly shaft 20 and the panel 312, and each surface is formed with a receiving groove 311a. On two opposite surfaces of the mounting block 311, a retaining side plate 313 is respectively fixed, and on the other two opposite surfaces, a retaining cover plate 314 is respectively fixed. The positioning seat 32 is connected to the mounting block 311 of the die head seat 31 through two guiding arms 315. Each guiding arm 315 is slidably disposed in the receiving groove 311a of the mounting block 311 connected to the retaining side plate 313, and a spring 316 is disposed in the receiving groove 311a. One end of the spring 316 abuts against the retaining side plate 313, and the other end abuts against the guiding arm 315. It can be understood that during winding, the frame power component 310 drives the frame 10 to drive the assembly shaft 20 and the die head assembly 30 to move. After the positioning seat 32 abuts against the iron core 200 to be wound, as the frame 10 continues to move, the die head seat 31 and the iron core 200 will move relative to each other and compress the spring 316, causing it to be compressed and form an elastic restoring force. When the die head seat 31 moves away from the iron core 200, the positioning seat 32 continues to maintain contact with the iron core 200 through the elastic restoring force of the spring 316.

[0038] See Figures 1 to 7 , the winding assembly 40 provided in this embodiment includes a winding component 41 for winding the enameled wire around the tooth part of the to-be-wound iron core 200. The winding component 41 is disposed on the periphery of the die head assembly 30 and can rotate relative to the die head assembly 30 with the axis of the assembly shaft 20 as the axis. It should be noted that the wire outlet end of the winding component 41 is located behind the end surface where the positioning seat 32 contacts the iron core 200 (i.e., in the direction away from the iron core 200 in the axial direction of the assembly shaft 20). When the winding component 41 rotates for winding, the enameled wire is rotationally wound around the iron core 200 in a way of being pulled backward and tightened by the winding component 41.

[0039] See Figures 1 to 7, the wire assembly 50 provided in this embodiment includes an upper wire lug 51 and a lower wire lug 52 for guiding the enameled wire to the tooth part. The upper wire lug 51 and the lower wire lug 52 are respectively arranged on the die head seat 31 and are spaced in the direction perpendicular to the bottom surface of the frame 10. The upper wire lug 51 and the lower wire lug 52 can be driven by the die head seat 31 to move axially along the assembly axis 20 relative to the positioning seat 32 at both ends of the iron core 200 respectively, and the upper wire lug 51 and the lower wire lug 52 can also move relative to the die head seat 31 in the direction perpendicular to the bottom surface of the frame 10. The die head seat 31 has a longitudinal section P passing through the axis of the assembly axis 20. The upper wire lug 51 and the lower wire lug 52 can be arranged parallel to the longitudinal section P or inclined to the longitudinal section P. In this embodiment, the upper wire lug 51 extends along the first direction F1, and the first direction F1 is inclined relative to the longitudinal section P. An upper guiding groove 321 is formed on the positioning seat 32 for enabling the upper wire lug 51 to move along the first direction F1 when the positioning seat 32 and the die head seat 31 move relative to each other. The upper mounting groove 511 extends along the first direction F1 and penetrates through both end faces of the upper wire lug 51; the lower wire lug 52 extends along the second direction F2, and the second direction F2 is inclined relative to the longitudinal section P. A lower guiding groove 322 is formed on the positioning seat 32 for enabling the lower wire lug 52 to move along the second direction F2 when the positioning seat 32 and the die head seat 31 move relative to each other. The lower mounting groove 521 extends along the second direction F2 and penetrates through both end faces of the upper wire lug 51. One end of the upper wire lug 51 is connected to the die head seat 31, and the other end extends along the first direction F1. The first direction F1 is inclined relative to the longitudinal section P and forms a first included angle a1 with the longitudinal section P. The range of the first included angle a1 can be but is not limited to 2° to 15°, preferably 5° to 7°. An upper guiding groove 321 extending along the first direction F1 is formed on the positioning seat 32. When the die head seat 31 drives the upper wire lug 51 to move relative to the positioning seat 32, it drives the upper wire lug 51 to move along the first direction F1 on a plane above the iron core 200 and parallel to the upper end face of the iron core 200; one end of the lower wire lug 52 is connected to the die head seat 31, and the other end extends along the second direction F2. The second direction F2 is inclined relative to the longitudinal section P and forms a second included angle a2 with the longitudinal section P. The range of the second included angle a2 can be but is not limited to 2° to 15°, preferably 5° to 7°. A lower guiding groove 322 extending along the second direction F2 is formed on the positioning seat 32. When the die head seat 31 drives the lower wire lug 52 to move relative to the positioning seat 32, it drives the lower wire lug 52 to move along the second direction F2 on a plane below the iron core 200 and parallel to the lower end face of the iron core 200.

[0040] See Figure 1 and Figure 7, in this embodiment, the upper wire lug 51 and the lower wire lug 52 provided are symmetrically arranged with respect to the axis of the assembly shaft 20. In this embodiment, the first angle α1 formed by the first direction F1 and the longitudinal section P is equal to the second angle α2 formed by the second direction F2 and the longitudinal section P. The upper wire lug 51 and the lower wire lug 52 are arranged in a manner that the first direction F1 and the second direction F2 intersect perpendicular to the bottom surface of the frame 10.

[0041] See Figure 1 and Figure 7 , specifically, the die head assembly 30 further includes an upper control seat 33 connected to the upper wire lug 51 and a lower control seat 34 connected to the lower wire lug 52. A first guide rail 35 extending in a direction perpendicular to the bottom surface of the frame 10 is provided on the die head seat 31. The upper control seat 33 and the lower control seat 34 are respectively slidably arranged on the first guide rail 35, and a tension spring is connected between the upper control seat 33 and the lower control seat 34; a second guide rail 36 is respectively provided on the upper control seat 33 and the lower control seat 34. The upper wire lug 51 and the lower wire lug 52 are respectively slidably mounted on the second guide rail 36 of the upper control seat 33 and the second guide rail 36 of the lower control seat 34. In this way, the upper control seat 33 and the lower control seat 34 are respectively mounted on the first guide rail 35 by sliders, and the upper wire lug 51 and the lower wire lug 52 are respectively mounted on the second guide rail 36 by sliders, which can improve the transmission accuracy and facilitate the assembly and maintenance of the equipment. It can be understood that when the die head seat 31 moves towards the positioning seat 32, the upper wire lug 51 and the lower wire lug 52 will move towards the first direction F1 and the second direction F2 respectively under the drive of the upper guiding slope and the lower guiding slope.

[0042] See Figure 1 and Figure 7, the push rod assembly 70 provided in this embodiment includes a push rod seat 71 that can move axially along the assembly shaft 20, an upper push rod 72 and a lower push rod 73 respectively connected to the push rod seat 71, and a push rod seat power member 74 for driving the movement of the push rod seat 71. The upper push rod 72 has an upper wire guiding slope 721 for guiding the movement of the enameled wire, and the lower push rod 73 has a lower wire guiding slope 731 for guiding the movement of the enameled wire; the upper wire support ear 51 has an upper mounting groove 511 located on its bottom surface for the upper push rod 72 to slide; the lower wire support ear 52 has a lower mounting groove 521 located on its bottom surface for the lower push rod 73 to slide. The push rod seat 71 is slidably disposed in the die head assembly 30. The push rod seat power member 74 is, but not limited to, a motor, which is supported on the horizontal plate 103. The extending directions of the upper push rod 72 and the lower push rod 73 respectively match those of the upper wire support ear 51 and the lower wire support ear 52. It should be noted that, due to the large slopes of the upper wire support ear 51 and the lower wire support ear 52, in order to avoid collision with the hook sleeve 202 during winding, when winding the first layer of the coil, after the upper wire support ear 51 and the lower wire support ear 52 guide and wind a predetermined number of turns, the upper push rod 72 extends from the upper wire support ear 51 and the lower push rod 73 extends from the lower wire support ear 52 to guide the winding of the enameled wire of this layer. However, the upper push rod 72 and the lower push rod 73 can be retracted, and the upper wire support ear 51 and the lower wire support ear 52 are used to wind the coils of the remaining layers. It is worth mentioning that the upper push rod 72 or the lower push rod 73 in this embodiment also has a wire hanging function. Before winding, the upper push rod 72 or the lower push rod 73 is driven to pass through the upper wire support ear 51 and the lower wire support ear 52 and then move to the corresponding hook position. The enameled wire on the winding component 41 is guided to the hook of the hook sleeve 202 through the slope on the surface of the upper push rod 72 or the lower push rod 73. After the winding component 41 rotates one circle, the enameled wire can be "knotted" and fixed on the hook, and then the iron core mounting frame is driven to rotate the iron core 200 by an angle of one tooth for winding.

[0043] From Figure 6 It can be seen that in this embodiment, the upper push rod 72 and the lower push rod 73 are respectively movably connected to the push rod seat 71. Concave portions 70a are formed on the side walls of the upper push rod 72 and the lower push rod 73 and protrusions 50a that cooperate and engage with the concave portions 70a are provided on the inner walls of the upper mounting groove 511 of the upper wire support ear 51 and the inner walls of the lower mounting groove 521 of the lower wire support ear 52. In this way, the upper push rod 72 and the upper wire support ear 51 can move relative to each other in the first direction F1, but cannot move relative to each other in the direction perpendicular to the bottom surface of the frame 10. Similarly, the lower push rod 73 and the lower wire support ear 52 can move relative to each other in the first direction F1, but cannot move relative to each other in the direction perpendicular to the bottom surface of the frame 10. In this way, when the upper wire support ear 51 and the lower wire support ear 52 move relative to the die head seat 31 in the direction perpendicular to the bottom surface of the frame 10, they will respectively drive the upper push rod 72 and the lower push rod 73 to move together.

[0044] SeeFigure 1 and Figure 7 Moreover, the winding device 100 provided in this embodiment further includes an ear lifting drive assembly 60 for moving the upper wire ear 51 and the lower wire ear 52 relative to the die head base 31 in a direction perpendicular to the bottom surface of the vertical frame 10. In this embodiment, the ear lifting drive assembly 60 includes a drive base 61 movably disposed in the die head base 31 along the axial direction of the assembly shaft 20 and a drive base power member 62 for moving the drive base 61. The drive base 61 includes two straight arm portions 611 respectively slidably disposed on the die head base 31 and a drive portion 612 connecting the two straight arm portions 611. The drive portion 612 has an upper drive surface 6121 for driving the upper control base 33 to move and a lower drive surface 6122 for driving the lower control base 34 to move.

[0045] Specifically, each straight arm portion 611 is respectively slidably disposed in a receiving groove 311a of the mounting block 311 connected with the retaining cover plate 314. The upper drive surface 6121 extends from the upper straight arm portion 611 towards the positioning seat 32 and downwards. The lower drive surface 6122 extends from the lower straight arm portion 611 towards the positioning seat 32 and upwards. The drive base power member 62 is, but not limited to, a motor, which is mounted horizontally. It can be understood that under the drive of the drive base power member 62, the drive base 61 can move relative to the die head base 31. When moving towards the positioning seat 32, it will push the upper control base 33 and the lower control base 34 to move away from each other, so as to spread the upper wire ear 51 and the lower wire ear 52, and wind the next layer of coil on the iron core 200.

[0046] See Figures 1 to 6 In addition, an upper drive mating wheel 37 is provided on the upper control base 33 provided in this embodiment, and the upper drive mating wheel 37 abuts against the upper drive surface 6121; a lower drive mating wheel 38 is provided on the lower control base 34, and the lower drive mating wheel 38 abuts against the lower drive surface 6122. In this way, the friction with the drive base 61 can be reduced, and the driving of the upper control base 33 and the lower control base 34 is smoother.

[0047] See Figures 1 to 8, the winding component 40 provided in this embodiment further includes a hollow rotary loop seat body 42 rotatably supported on the first vertical plate 101 and a winding power member 43 for rotating the rotary loop seat body 42.

In this embodiment, a first bearing 81 is provided between the rotary loop seat body 42 and the first vertical plate 101, and a second bearing 82 is provided between the rotary loop seat body 42 and the assembly shaft 20.

Driven by the winding power member 43, the rotary loop seat body 42 rotates and drives the winding member 41 to rotate.

[0048] See Figure 1 , Figure 2 , Figure 5 , Figure 8 , in this embodiment, a third guide rail 104 is provided on the horizontal plate 103. The third guide rail 104 extends along the assembly shaft 20.

The number of second translation seats 106 is, but not limited to, one. That is to say, the push rod seat power member 74 can simultaneously drive the push rod seat 71 in the two die head assemblies 30 to move, while the drive seats 61 in the two die head assemblies 30 are driven to act separately by the two drive seat power members 62.
