Description

Technical Field

[0001] The invention relates to the technical field of iron core winding equipment, in particular to a winding machine. Background Art

[0002] The motor core is an important part of the motor. It carries the magnetic field and mechanical force of the motor and has a vital 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. Each silicon steel sheet is specially treated to reduce iron loss and hysteresis loss, thereby improving the efficiency of the motor.

[0003] At present, for motors, stator core winding and rotor core winding are important links, which are related to product quality issues. For stator and rotor cores with notches facing outward, flying fork winding machines are often used for winding. Existing winding machines include a die head and a winding component. The winding component can drive the enameled wire to move around the winding component and wrap the enameled wire around the core. The die head has a fixed part in contact with the core and a moving part that moves relative to the fixed part during winding. A spring is provided between the fixed part and the moving part, and the fixed part is kept on the core during the winding process by the spring. However, since the enameled wire is wound around the core by the winding component in a backward pulling manner when the winding component rotates for winding, if the pulling force is too large, the fixed part of the die head will be pulled backward, thereby affecting the winding effect, and excessive elastic force of the spring can easily damage the core.

The frame power member 11 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 substrate 101.

[0033] See also Figures 1 to 4The winding machine 100 provided in this embodiment is used to wind the iron core 200, and the iron core 200 can be a straight slot iron core 200 or a skew slot iron core 200, which is supported on the base plate 101 by an iron core 200 mounting frame (not shown). In this embodiment, the iron core 200 is but not limited to a skew slot iron core 200, which includes a core shaft 201, a hook 202 mounted on the core shaft 201, and an iron core lamination 203.

[0034] See also Figures 1 to 4 The mounting shaft 20 provided in this embodiment is a hollow structure. The mounting shaft 20 is rotatably supported on the frame 10 through a bearing.

[0037] See also Figures 1 to 4 The winding assembly 40 provided in this embodiment includes a winding component 41 for winding the enameled wire on the tooth portion of the iron core 200 to be wound. The winding component 41 is arranged on the peripheral side of the die head assembly 30 and can rotate relative to the die head assembly 30 with the axis of the installation shaft 20 as the axis. It should be noted that the outlet end of the winding component 41 is located behind the end surface of the positioning seat 32 in contact with the iron core 200 (that is, in the direction away from the iron core 200 in the axial direction of the installation shaft 20). When the winding component 41 rotates to wind the wire, the enameled wire is rotated and wound on the iron core 200 by the winding component 41 in a backward tightened manner.

[0038] See also Figures 1 to 4 The wire assembly 50 provided in this embodiment 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 movable seat 33 and are spaced in a direction perpendicular to the bottom surface of the frame 10. The upper wire support ear 51 and the lower wire support ear 52 can be driven by the movable seat 33 to move relative to the positioning seat 32 along the axial direction of the mounting shaft 20 at both ends of the iron core 200. The upper wire support ear 51 and the lower wire support ear 52 can also move relative to the movable seat 33 in a direction perpendicular to the bottom surface of the frame 10 (i.e., perpendicular to the surface of the substrate 101). The die head seat 31 has a longitudinal section (not shown) passing through the axis of the mounting shaft 20. The lug 51 and the lower wire lug 52 may be arranged parallel to the longitudinal section or inclined to the longitudinal section. In the present embodiment, the upper wire lug 51 and the lower wire lug 52 both extend along the axial direction of the mounting shaft 20, that is, the upper wire lug 51 and the lower wire lug 52 are arranged parallel to the longitudinal section. An upper guide groove 321 is formed on the positioning seat 32 for allowing the upper wire lug 51 to move when the positioning seat 32 and the die head seat 31 move relative to each other. The upper guide groove 321 extends along the axial direction of the mounting shaft 20. A lower guide groove 322 is formed on the positioning seat 32 for allowing the lower wire lug 52 to move when the positioning seat 32 and the die head seat 31 move relative to each other. The lower guide groove 322 extends along the axial direction of the mounting shaft 20.

[0039] In other embodiments, the die head seat 31 has a longitudinal cross-section passing through the axis of the mounting shaft 20; the upper wire support ear 51 extends along a first direction (not shown in the figure), the first direction is inclined relative to the longitudinal cross-section, and the upper mounting groove extends along the first direction; the lower wire support ear 52 extends along a second direction (not shown in the figure), the second direction is inclined relative to the longitudinal cross-section, and the lower mounting groove extends along the second direction.

[0040] See also Figures 1 to 4 , Figure 6The frame 10 provided in this embodiment is provided with a lug lifting drive device 70, which is used to move the upper wire lug 51 and the lower wire lug 52 relative to the die assembly 30 in a direction perpendicular to the bottom surface of the frame 10. The upper wire lug 51 and the lower wire lug 52 are both installed in the moving seat 33, and can move relative to the positioning seat 32 under the drive of the moving seat 33. They can also move relative to the direction perpendicular to the bottom surface of the frame 10 under the drive of the lug lifting drive device 70. It should be noted that when winding the same layer of enameled wire, the die assembly 30 will drive the upper wire lug 51 and the lower wire lug 52 to move from The relative positioning seat 32 moves from the initial position, and the winding component 41 rotates at the same time. For each rotation of the winding component 41, the moving seat 33 advances a diameter of the enameled wire. After the coil of this layer is wound, the moving seat 33 drives the upper wire support ear 51 and the lower wire support ear 52 to return to the initial position. The support ear lifting drive device 70 moves the upper wire support ear 51 and the lower wire support ear 52 in opposite directions in a direction perpendicular to the bottom surface of the frame 10 by a diameter of the enameled wire. After opening, the upper wire support ear 51 and the lower wire support ear 52 will guide the winding component 41 to wind the next layer (outer layer) of the coil.

[0041] See also Figures 1 to 4 The die head assembly 30 provided in this embodiment also includes a wire hanging plate 36 disposed on the movable seat 33 and movable relative to the movable seat 33 along the axial direction of the mounting shaft 20. The wire hanging plate 36 includes a wire hanging portion for fixing the enameled wire on the iron core 200. In this embodiment, the wire hanging plate 36 is connected to the lug lifting drive device 70 and can move relative to the movable seat 33. The bottom of the wire hanging portion is provided with a wire hanging groove 36a that avoids the hook on the hook sleeve 202. It is worth mentioning that before winding, the wire hanging plate 36 is driven to pass through the positioning seat 32 and 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 inclined surface of the wire hanging portion. After the winding component 41 rotates one circle, the enameled wire can be "knotted" and fixed on the hook, and then the iron core 200 mounting frame is driven to rotate the iron core 200 by an angle of a tooth before winding.

[0042] See also Figures 1 to 4 , Figure 6 The lug lifting drive device 70 provided in this embodiment includes a hollow driving shaft 71, a lug lifting power member 72, a connecting seat 73 and an operating rod 74. The driving shaft 71 has a first end 71a and a second end 71b opposite to each other. The lug lifting power member 72 is connected to the first end 71a and is used to drive the driving shaft 71 to move. The connecting seat 73 is movably arranged in the die head seat 31 along the axial direction of the mounting shaft 20. The second end 71b is connected to the connecting seat 73 and can rotate relative to the connecting seat 73. The operating rod 74 is used to drive the upper wire lug 51 and the lower wire lug 52 to move in a direction along the bottom surface of the vertical frame 10. The operating rod 74 is fixedly connected to the connecting seat 73.

[0043] See also Figures 1 to 4 The die assembly 30 provided in this embodiment further includes an upper control block 37 connected to the upper wire support ear 51 and a lower control block 38 connected to the lower wire support ear 52. The upper control block 37 and the lower control block 38 are respectively arranged on the bottom surface of the upper frame 10 of the movable seat 33 in a direction perpendicular to the bottom surface of the frame 10. The upper control block 37 has an upper concave cavity 371 for the operating rod 74 to extend into and an upper driving surface 372 located on the bottom surface of the upper concave cavity 371 and abutting against the end of the operating rod 74. The upper driving surface 372 It includes an upper horizontal portion 373 and an upper inclined portion 374 extending obliquely from the upper horizontal portion 373 toward the connecting seat 73 and in the direction of the mounting shaft 20; the lower control block 38 has a lower concave cavity 381 for the operating rod 74 to extend into and a lower driving surface 382 located on the bottom surface of the lower concave cavity 381 and abutting against the end of the operating rod 74, the lower driving surface 382 includes a lower horizontal portion 383 and a lower inclined portion 384 extending obliquely from the lower horizontal portion 383 toward the connecting seat 73 and in the direction of the mounting shaft 20. In the present embodiment, the movable seat 33 has a receiving groove 33a extending perpendicularly to the bottom surface of the frame 10, and the receiving groove 33a passes through the two end surfaces of the movable seat 33. The upper control block 37 and the lower control block 38 are respectively arranged in the receiving groove 33a. The two ends of the upper control block 37 along the axial direction of the mounting shaft 20 extend to the outside of the movable seat 33, and the side wall surface of the upper control block 37 protrudes to form an upper limit convex portion 375, which abuts against the outer surface of the movable seat 33 and moves relative to each other in the axial upper limit of the mounting shaft 20; the two ends of the lower control block 38 along the axial direction of the mounting shaft 20 extend to the outside of the movable seat 33, and the side wall surface of the lower control block 38 protrudes to form a lower limit convex portion 385, which abuts against the outer surface of the movable seat 33 and moves relative to each other in the axial upper limit of the mounting shaft 20. In this way, the upper control block 37 and the lower control block The block 38 can move relatively in a direction perpendicular to the bottom surface of the frame 10, and cannot move relatively between the movable seat 33 in the axial direction of the mounting shaft 20. It can be understood that when the operating rod 74 moves axially toward the iron core 200 along the mounting shaft 20, the end of the operating rod 74 abuts against the upper horizontal portion 373 and the lower horizontal portion 383 in the upper control block 37 and the lower control block 38, and the movement of the operating rod 74 does not drive the upper control block 37 and the lower control block 38 to move in a direction perpendicular to the bottom surface of the frame 10; when the operating rod 74 moves axially away from the iron core 200 along the mounting shaft 20, the end of the operating rod 74 abuts against the upper inclined portion 374 and the lower inclined portion 384 in the upper control block 37 and the lower control block 38, thereby driving the upper control block 37 connected to the upper wire support ear 51 and the lower control block 38 connected to the lower wire support ear 52 to move away from each other.

[0044] See also Figures 1 to 4In this embodiment, both ends of the movable seat 33 are connected with cover plates 331 to close the openings at the ends, and elastic elements (not shown) are arranged between the cover plate 331 and the upper control block 37 and between the cover plate 331 and the lower control block 38. The elastic elements are but not limited to springs. Thus, under the action of the elastic elements, when the operating rod 74 moves axially toward the iron core 200 along the mounting shaft 20 on the upper inclined portion 374 and the lower inclined portion 384, and slides off the upper inclined portion 374 and the lower inclined portion 384, the upper control block 37 and the lower control block 38 will be pushed to reset to the connecting seat 73 respectively.

[0045] See also Figures 1 to 6The winding translation driving device 60 of this embodiment is used to make the movable seat 33 move along the axial direction of the installation shaft 20. The winding translation driving device 60 includes a hollow control shaft 61, a first support seat 62 and a translation force member 63 for driving the control shaft 61 to move along the axial direction of the installation shaft 20.
