Description

Technical Field

[0001] The invention belongs to the technical field of motor coil winding, and in particular relates to a multi-row winding device for a motor stator coil. Background Art

[0002] There are mainly the following methods and related steps for motor stator winding: First, centralized winding: Winding process: The concentrated winding is generally composed of one or several rectangular frame coils. First, the shape and size of the coil are determined according to the motor design requirements, and then the wire is wound on the rectangular frame according to the designed number of turns and winding direction. After winding, it is usually wrapped with gauze to shape it, and then embedded in the iron core of the salient magnetic pole after varnish dipping and drying. This winding method is commonly used for the excitation coils of DC motors and universal motors, as well as the main pole windings of single-phase shaded pole motors.

[0003] Second, distributed winding: Winding process: Several rectangular coils of different sizes in the same coil group are embedded one by one in the same center position and arranged in a U-shape. When winding, first wind the small coil in the center position, and then wind the outer coils in order from small to large. This winding method is divided into single-layer and multi-layer. Single-layer concentric winding is relatively simple, and each coil is only wound with one layer of wire; multi-layer concentric winding requires winding multiple layers of wire at the same coil position, and attention should be paid to interlayer insulation during the winding process. Application scenario: This type of stator winding is generally used for single-phase motors and some small-power three-phase asynchronous motors.

[0004] However, the existing winding equipment has high process requirements, complex structure and high cost. In addition, after winding, special machines are needed for insulation treatment, such as winding insulation layer. Different combinations of motor stator wires have different effects, and different winding combinations have different winding methods and steps. In the specific winding process, a special console is needed to control it, which is troublesome to use.

[0051] The winding bracket 2 used in the present invention has the same structure, shape and material as the winding bracket 2 of the stator of the conventional motor 3009, and the winding bracket 2 is a prior art. In the present invention, the wire 7 is spirally wound on the elastic insulating sleeve 5, such as Fig.21 As shown; the elastic insulating sleeve 5 is composed of two layers of inner and outer circular insulating sleeves, and the wire 7 is wound on the inner insulating sleeve; when winding the wire 7, the elastic insulating sleeve 5 is nested on the winding assembly 3, and the winding bracket is placed on the mounting platform 1, so that the elastic insulating sleeve 5 is located on the upper side of the winding bracket 2 and the elastic insulating sleeve 5 is directly opposite to one of the split support plates 2001 on the winding bracket 2; after the wire 7 is wound, the elastic insulating sleeve 5 on the lower side is squeezed downward by the forming assembly 4; under the cooperation of the forming assembly 4 and the winding bracket, the elastic insulating sleeve 5 and the elastic insulating sleeve 5 wound on the elastic insulating sleeve are pressed downward.

[0052] In a further embodiment, Figure 2 As shown, the mounting platform 1 includes a base 1001, an L-shaped support rod 1002, a mounting plate 1003, a mounting rod 1004, and a mounting frame 1005, wherein the base 1001 is fixed to the workbench by bolts, and the mounting plate 1003 is fixedly mounted on the upper side of the base 1001 by two L-shaped support rods 1002; the mounting plate 1003 is fixedly mounted with a mounting rod 1004 on the upper side, and the mounting frame 1005 is fixedly mounted on the upper end of the mounting rod 1004.

[0053] In a further embodiment, Figure 5 As shown, the winding assembly 3 includes a fixed support 3001, a mounting sleeve 3002, a fixing sleeve 3003, a support column 3004, a first electric push rod 3005, a second electric push rod 3006, a limit block 3007, a third electric push rod 3008, a motor 3009, a mounting plate 3016, a fourth electric push rod 3017, a pressure block 3018, a fifth electric push rod 3019, a first guide rod 3020, a drive ring 3021, and a cutting assembly 3022, wherein as Figure 3As shown, the fixed support 3001 is fixedly installed on the upper side of the base 1001, the mounting sleeve 3002 is rotatably installed in the fixed support 3001, the middle of the mounting sleeve 3002 is rotatably installed with a fixed sleeve 3003, the fixed sleeve 3003 is fixedly installed with a first electric push rod 3005, the output shaft of the first electric push rod 3005 is fixedly installed with a support column 3004, and the elastic insulating sleeve 5 is sleeved on the support column 3004; Fig.11 As shown, a plurality of first guide rods 3020 are fixedly installed uniformly in the circumferential direction at one end of the installation sleeve 3002, and a drive ring 3021 is fixedly installed at one end of the first guide rod 3020 away from the installation sleeve 3002; a plurality of fifth electric push rods 3019 are fixedly installed uniformly in the circumferential direction between the drive ring 3021 and the installation sleeve 3002; a slot 3023 is provided on the drive ring 3021 for the wire 7 to pass through; Fig.11 , 12 As shown, a cutting assembly 3022 capable of cutting the electric wire 7 is fixedly mounted on one end of the mounting sleeve 3002; a motor 3009 is fixedly mounted on the upper side of the base 1001, and the motor 3009 can drive the mounting sleeve 3002 to rotate.

[0054] Controlling the first electric push rod 3005 can control the support column 3004 to slide relative to the fixed sleeve 3003; controlling the fifth electric push rod 3019 can control the drive ring 3021 to slide relative to the mounting sleeve 3002, and the first guide rod 3020 can guide the sliding of the drive ring 3021.

[0055] After the wire 7 is wound, the cutting assembly 3022 can be controlled to cut the wire 7, so that the wound wire 7 is disconnected from the unwound wire 7.

[0056] like Figure 7 , 8 As shown, a third electric push rod 3008 is fixedly installed on one side of the fixed support 3001, a mounting plate 3016 is fixedly installed on the output end of the third electric push rod 3008, a fourth electric push rod 3017 is fixedly installed on the mounting plate 3016, and a pressure block 3018 is fixedly installed on the output end of the fourth electric push rod 3017; the pressure block 3018 applies pressure to the inserted wire 7.

[0057] like Figure 3 , 5 As shown in FIG. 10 , the second electric push rod 3006 is fixedly mounted on the mounting plate 1003 , and a limit block 3007 is fixedly mounted on the output shaft of the second electric push rod 3006 . The limit block 3007 is inserted into the support column 3004 to limit the rotation of the support column 3004 .

[0058] In a further embodiment, Fig. 9As shown, one end of the elastic insulating sleeve 5 is provided with a wire outlet hole.

[0059] like Figure 6 As shown, the installation sleeve 3002 is provided with a threading hole 3015. Figure 5 As shown, the wire 7 passes through the fixed support 3001 and then passes into the wire threading hole 3015. After passing through the wire threading hole 3015, the wire 7 passes through the clamping groove 3023 on the driving ring 3021 and finally passes out from the corresponding wire outlet hole of the elastic insulating sleeve 5.

[0060] In a further embodiment, Figure 6 As shown, a first gear 3010 is fixedly mounted on the output shaft of the motor 3009, a mounting shaft 3013 is rotatably mounted on the fixed support 3001, a second gear 3011 is fixedly mounted on one end of the mounting shaft 3013, and the second gear 3011 is meshed with the first gear 3010; a third gear 3012 is fixedly mounted on the other end of the mounting shaft 3013, a gear ring 3014 is fixedly mounted on the mounting sleeve 3002, and the gear ring 3014 is meshed with the third gear 3012.

[0061] Before winding, the first electric push rod 3005 and the fifth electric push rod 3019 are both in a retracted state. When winding, first control the first electric push rod 3005 to work so that its output end drives the support column 3004 to move outward, and the elastic insulating sleeve 5 is put on the support column 3004; then, place the winding bracket on the upper side of the base 1001 and make the elastic insulating sleeve 5 located on the upper side of the winding bracket 2 and the elastic insulating sleeve 5 is facing one of the split support plates 2001 on the winding bracket 2; then, control the second electric push rod 3006 to work so that the output end of the second electric push rod 3006 drives the limit block 3007 to insert into the support column 3004 to limit the rotation of the support column 3004; then, insert the wire 7 to be wound into the fixed support 3001 , the wire 7 passes through the fixed support 3001 and then passes through the wire threading hole 3015. After passing through the wire threading hole 3015, the wire 7 passes through the card slot 3023 on the drive ring 3021 and finally passes through the corresponding wire outlet hole of the elastic insulating sleeve 5; then the third electric push rod 3008 is controlled to work, so that the output end of the third electric push rod 3008 drives the mounting plate 3016 to slide, and the mounting plate 3016 drives the fourth electric push rod 3017 to slide, and the sliding of the fourth electric push rod 3017 drives the pressing block 3018 to slide. When the pressing block 3018 moves to the inner end surface close to the elastic insulating sleeve 5, the fourth electric push rod 3017 is controlled to work, so that the output end of the fourth electric push rod 3017 drives the mounting plate 3016 to slide, and the mounting plate 3016 drives the fourth electric push rod 3017 to slide. The end drives the pressing block 3018 to move downward and press the corresponding wire 7; then the motor 3009 is controlled to work. When the motor 3009 is working, the motor 3009 will drive the first gear 3010 to rotate. The rotation of the first gear 3010 drives the second gear 3011 to rotate. The rotation of the second gear 3011 drives the installation shaft 3013 to rotate. The rotation of the installation shaft 3013 drives the third gear 3012 to rotate. The rotation of the third gear 3012 drives the ring gear 3014 to rotate. The rotation of the ring gear 3014 drives the installation sleeve 3002 to rotate. The rotation of the installation sleeve 3002 drives the corresponding fifth electric push rod 3019 and the first guide rod 3020 to rotate around the axis of the installation sleeve 3002. The rotation of the first guide rod 3020 will drive the driving ring 3021 to rotate. The driving ring 3021 rotates through the slot 3023 to drive the wire 7 to rotate around the axis of the support column 3004. In this process, because the side of the wire 7 close to the inner end of the elastic insulating sleeve 5 is pressed and fixed by the pressing block 3018, when the driving ring 3021 drives the wire 7 to rotate around the axis of the support column 3004, the wire 7 will be wound around the insulating sleeve of the inner layer of the elastic insulating sleeve 5. In this process, it is necessary to control the fifth electric push rod 3019 to work and drive the driving ring 3021 to slide to the outside of the elastic insulating sleeve 5. As a result, the wire 7 will be wound into a spiral shape on the insulating sleeve of the inner layer of the insulating sleeve.When the driving ring 3021 completely slides out of the elastic insulating sleeve 5, the control motor 3009 stops working, and the fourth electric push rod 3017 is controlled to work, so that the output end of the fourth electric push rod 3017 drives the pressing block 3018 to move up and disengage from the corresponding wire 7; then the third electric push rod 3008 is controlled to work, so that the output end of the third electric push rod 3008 drives the mounting plate 3016 to slide, the mounting plate 3016 drives the fourth electric push rod 3017 to slide, and the sliding of the fourth electric push rod 3017 drives the pressing block 3018 to slide, so that the pressing block 3018 slides out of the elastic insulating sleeve 5.;

[0062] During this process, because the support column 3004 is limited by the limit block 3007 , the rotation of the fixing sleeve 3003 for mounting the support column 3004 and the first electric push rod 3005 is restricted and will not interfere with the rotation of the mounting sleeve 3002 .

[0063] The cutting assembly 3022 installed on the installation sleeve 3002 will not affect the winding of the wire 7 because it will rotate together with the installation sleeve 3002 and the wire 7 during the circumferential rotation of the installation sleeve 3002.

[0064] In a further embodiment, Figure 2 As shown, the forming assembly 4 includes a second guide rod 4001, a sixth electric push rod 4002, and a forming mold 4003, wherein the forming mold 4003 is fixedly mounted on the lower side of the mounting frame 1005 through the second guide rod 4001, a sixth electric push rod 4002 is installed between the forming mold 4003 and the mounting frame 1005, and the forming mold 4003 has a U-shaped groove with an opening facing downward.

[0065] After the winding of the wire 7 is completed, the sixth electric push rod 4002 is controlled to work so that the output end of the sixth electric push rod 4002 drives the forming mold 4003 to move downward, exerting a pressure on the elastic insulating spring, which can exert a resistance along the axis of the support sleeve on the elastic insulating sleeve 5, but will not cause the elastic insulating sleeve 5 to deform; then the first electric push rod 3005 is controlled to work so that its output end drives the support column 3004 to move and detach from the elastic insulating sleeve 5.

[0066] Afterwards, the sixth electric push rod 4002 continues to control the forming mold 4003 to move downward, and the elastic insulating sleeve 5 on the lower side is squeezed downward by the forming mold 4003; with the cooperation of the forming mold 4003 and the winding bracket, the elastic insulating sleeve 5 and the electric wire 7 wound on the elastic insulating sleeve 5 are squeezed into a U shape and clamped on the winding bracket.
