Description

TECHNICAL FIELD

[0002] Flat wire motor is one of the development directions of motors, and flat copper wire replaces round copper wire in the armature due to better performance. The flat copper wire cannot be easily bent due to its structure, and the flattening of the closed end leads to different lengths of the open end during the manufacturing process. Therefore, the flat copper wire must be cut flat to facilitate subsequent processes.

[0003] There are mainly two ways to cut the flat copper wire in the prior art, namely manual beveling pliers cutting and mechanical cutting. The manual cutting is slow and has poor process consistency, and the position and precision after cutting are difficult to guarantee. The mechanical cutting adopts a circumferential cutting method, which can cause the spacing between the flat copper wires to be enlarged, and the cutting shape also follows the circumferential direction, which is not conducive to the subsequent welding process. Some methods adopt a single tool radial cutting method, which can avoid some problems of the circumferential cutting method, but the efficiency is low, the control requirement is high, and it is difficult to predict whether other problems will occur when the flat wire stator rotates.

[0049] With reference to the drawings and specifically to the embodiments herein, a further specific description of the present application follows.

[0050] In order for those skilled in the art to better understand the present application, the present application will be further described in detail below with reference to the drawings and specific embodiments.

[0051] Reference is made to the drawings accompanying the specification Figure 1 -attached Figure 3 , attached Figure 1 is a structure schematic diagram of the motor flat copper wire cutting device provided by the embodiments of the present application, Figure 2 is a front view of the motor flat copper wire cutting device provided by the embodiments of the present application, Figure 3 is an assembly schematic diagram of the flat copper wire stator and the limiting disc provided by the embodiments of the present application, including: the motor flat copper wire cutting device for cutting the flat copper wire of the flat wire motor, including: a main plate 1, a cutting component 3 and a stator moving mechanism. The cutting component 3 includes: a mounting frame 4 provided on the main plate 1, and a plurality of radial cutter assemblies and a cutter driving mechanism 5 are provided on the mounting frame 4. The stator moving mechanism is provided on the main plate 1, the main plate 1 is used for placing the flat copper wire stator 2, and the flat copper wire stator 2 is used for installing the flat copper wire of the flat wire motor. The cutter driving mechanism 5 is used for driving the plurality of radial cutter assemblies to cut all the wire ends of the flat copper wire stator 2 at the same time, and the cutting work is completed at one time. And the stator moving mechanism is used for moving the flat copper wire stator 2 to the specified position and cooperating with the cutting component 3 to complete the cutting. The cutting device of the present application can cut all the flat copper wires on the flat copper wire stator synchronously, increase the cutting efficiency, and the cutting plane is neat.

[0052] In the working preparation state, the flattened flat copper wire stator 2 is provided with the opening end upward, the wire end of the flat copper wire is stretched out from the opening end, and the stator moving mechanism is sent into the plurality of radial cutter assemblies for cutting. The setting mode of the flat copper wire on the flat copper wire stator 2 can refer to the prior art, which will not be expanded herein.

[0053] In a conventional case, a supporting leg 14 is provided at the bottom of the main plate 1, so as to ensure that the motor flat copper wire cutting device is stably arranged on the ground.

[0054] Further, reference is made to the drawings accompanying the specification Figure 4 -attached Figure 6 , Figure 4 is a structure schematic diagram of the cutting component provided by the embodiments of the present application, Figure 5 is a structure schematic diagram of the limiting disc provided by the embodiments of the present application, Figure 6As shown in the sectional view of the limiting disc provided by the embodiment of the present application, the multi-radial cutter assembly comprises a support plate 6, a limiting disc 7, a cutter cover plate 8 and a synchronous cutting knife assembly connected with the cutter driving mechanism 5. The support plate 6 is connected below the mounting frame 4, and the through hole is provided through the support plate 6 in the thickness direction. The limiting disc 7 is arranged on the top surface of the support plate 6, and the limiting disc 7 is located above the through hole. The top surface of the limiting disc 7 is uniformly provided with a plurality of limiting grooves 71, and the plurality of limiting grooves 71 are uniformly distributed along the radial direction of the limiting disc 7.

[0055] The bottom surface of the limiting disc 7 is provided with a wire passing hole 72 corresponding to the limiting groove 71. The cutter cover plate 8 is installed on the top surface of the limiting disc 7, thereby covering and sealing the top surface of all the limiting grooves 71, so that each limiting groove 71 forms a complete channel. The limiting groove 71 extending to the outside of the edge of the limiting disc 7 is provided with an opening.

[0056] When the flat copper wire stator 2 moves to the specified position, the wire heads of the flat copper wire stator 2 can extend into the limiting grooves 71 through the wire passing holes 72, and after all the wire heads extend into different limiting grooves 71, the cutting ends of the synchronous cutting knife assembly can extend into the limiting disc 7 along the outside of the limiting grooves 71. The plurality of cutting ends gradually move inward along the channels formed by the limiting grooves 71 from the circumference, and finally cut all the wire heads of the flat copper wire stator 2 at the same time.

[0057] Further, referring to the drawings attached to the specification Figure 7 and the drawings attached to the specification Figure 8 , Figure 7 As shown in the assembly schematic view of one of the bending cutters and the limiting disc provided by the embodiment of the present application, Figure 8 As shown in the assembly schematic view of the limiting disc and the cutter cover plate provided by the embodiment of the present application, the synchronous cutting knife assembly comprises a cutter mounting disc 9 and a bending cutter 10.

[0058] The bending cutter 10 is provided at the edge of the cutter mounting disc 9, and each bending cutter 10 comprises a mounting handle and a cutting knife rotatably connected to the mounting handle. The mounting handle is fixed on the cutter mounting disc 9, and the end of the cutting knife extends into the limiting groove 71.

[0059] The cutter driving mechanism 5 is connected with the cutter mounting disc 9, and can drive the cutter mounting disc 9 to move towards and away from the limiting disc 7. By adjusting the distance between the two, the cutting knife rotates relative to the mounting handle, and finally moves in the limiting groove 71 to complete the cutting.

[0060] In one embodiment of this application, the number and position of the bending cutters 10 along the edge of the cutter mounting plate 9 correspond to the number and position of the openings in the limiting grooves 71 on the outer side of the limiting disc 7. This ensures that the multiple bending cutters 10 are of the same specification, forming a cutter group circumferentially between the cutter mounting plate 9 and the limiting disc 7. When the cutter mounting plate 9 approaches or moves away from the limiting disc 7, all the cutters in the cutter group move synchronously, ensuring that the rotating cutting blade moves in a consistent manner within the limiting grooves 71. It is foreseeable that the wire-passing holes 72 of the limiting disc 7 are evenly distributed corresponding to the limiting grooves 71, ensuring that the wire ends to be cut are also kept in the same plane, allowing the cutting blade to complete the cutting synchronously.

[0061] The rotational connection between the cutting blade and the mounting handle can refer to existing technologies. For example, a rotating rod can be set up, with the two ends of the rotating rod rotatably connecting the cutting blade and the mounting handle respectively. This converts the displacement of the tool mounting disc 9 relative to the limiting disc 7 in the direction of the cutting blade in the length direction of the limiting groove 71. Of course, other rotational structures that achieve this effect are also applicable, and will not be elaborated on here.

[0062] Furthermore, the aforementioned tool drive mechanism 5 is configured as a telescopic motor, and the moving end of the telescopic motor is connected to the tool mounting plate 9, thereby driving the tool mounting plate 9 to move towards and away from the limiting disc 7.

[0063] Further, refer to the attached instruction manual. Figure 9 , Figure 9 for Figure 4 In another perspective, the structure is shown in the schematic diagram. The center of the limiting disc 7 is provided with a discharge hole, and a waste collector 11 connected to the limiting disc 7 is provided below the discharge hole. The limiting groove 71 extends into the discharge hole, and the synchronous cutting blade assembly can continue to push the cut wire end towards the discharge hole until it is pushed into the waste collector 11.

[0064] The specific design of the waste collector 11 can be found in existing technologies, and will not be described in detail here.

[0065] Furthermore, the aforementioned stator moving mechanism includes: a loading / unloading mechanism 12 and a lifting mechanism 13. The loading / unloading mechanism 12 is disposed on the top surface of the main body plate 1 and is used to transport the flat copper wire stator 2 to below the multi-radial tool assembly. The multi-radial tool assembly is disposed on the main body plate 1 and is used to move the flat copper wire stator 2 vertically to engage with the multi-radial tool assembly.

[0066] Further, refer to the attached instruction manual. Figure 10 , Figure 10 This is a schematic diagram of the loading and unloading mechanism provided in the embodiment of this application. The loading and unloading mechanism 12 includes: a guide rail 121, a stator moving disk 122, and a drive motor 123.

The stator moving plate 122 is lapped on the moving end of the driving motor 123 through the lapping piece 124, and the driving motor 123 is used for driving the stator moving plate 122 to move along the guide rail 121.

[0068] The lapping piece 124 is separated from the limiting position of the moving end of the driving motor 123 when being moved upward, and when the lapping piece 124 is naturally lapped due to gravity, the lapping piece 124 can move with the moving end. The specific cooperation structure of the lapping piece 124 and the moving end can refer to the prior art, and will not be expanded herein.

[0069] Further, referring to the accompanying drawings Figure 11 , Figure 11 The jacking mechanism 13 provided by the embodiment of the present application includes a positioning frame 131, a lifting motor 132 and a moving plate 133.

[0070] The positioning frame 131 is installed below the main plate 1, the output end of the lifting motor 132 penetrates the positioning frame 131 from bottom to top to connect the moving plate 133, and the top surface of the moving plate 133 is provided with a positioning piece 134 and a clamping jaw 135. The lifting motor 132 lifts the moving plate 133 to the position where the positioning piece 134 is connected with the positioning hole of the stator moving plate 122, the clamping jaw 135 is used for positioning the flat copper wire stator 2, the lifting motor 132 can lift the positioned flat copper wire stator 2 to cooperate with the cutting component 3, and the cooperation and positioning mode of the clamping jaw 135 and the flat copper wire stator 2 can refer to the prior art.

[0071] In one embodiment of the present application, when the device starts to work, the flat copper wire stator 2 with the installed flat copper wire is placed on the stator moving plate 122 with the opening end upward, then the driving motor 123 drives the stator moving plate 122 to move to the position directly below the cutting component 3, the lifting motor 132 lifts the moving plate 133 until the positioning piece 134 is connected with the positioning hole of the stator moving plate 122, the clamping jaw 135 fixes the flat copper wire stator 2 after positioning, the lifting motor 132 continues to lift the whole structure to the cooperation position, so that the wire head of the flat copper wire stator 2 extends into the wire passing hole 72, and subsequent cutting is completed through the multi-radial cutter assembly and the cutter driving mechanism 5.

[0072] Further, the inner edge of the wire passing hole 72 is provided as a circular arc guide surface, the circular arc guide surface can guide the wire head of the flat copper wire stator 2, and facilitate the wire head to extend into the corresponding limiting groove 71.
