Description

Technical Field

[0001] The present invention relates to a material dividing and arranging device and a material dividing method for flat wire motor coils of new energy vehicles, belonging to the technical field of material dividing equipment for flat wire motor coils of new energy vehicles. Background Art

[0002] Traditional motor stators use round enameled wire windings, which often suffer from low effective copper area and high copper loss. To increase the effective copper area, the copper wires need to be more regularly arranged within the slots. Therefore, a hairpin winding structure is used to address these issues. The hairpin winding structure consists of multiple hairpin-shaped flat-wire motor coils. Its installation principle is as follows: the flat-wire motor coil windings are first formed into multiple hairpin-like shapes, then threaded into prefabricated stator slots. The windings are twisted and welded together at the other end to form a complete winding. Before inserting the multiple hairpin-shaped flat-wire motor coils, the flat-wire motor coil group must be pre-cut to facilitate subsequent installation.

[0003] There are two existing methods for classifying and loading flat wire motor coils: manual sorting and mechanical sorting. Manual sorting involves workers taking one flat wire motor coil from each flat wire motor coil group and inserting the multiple flat wire motor coils into prefabricated stator slots in sequence. However, due to slight differences in the inner diameters of the multiple hairpin-shaped flat wire motor coils of a motor, manual sorting and arrangement can easily confuse the flat wire motor coils due to individual differences among workers and relying solely on visual identification, resulting in incorrect arrangement of the flat wire motor coils, ultimately affecting the motor's yield rate. Furthermore, manual sorting not only involves a large amount of manual labor, but also has low efficiency in sorting and arranging the flat wire motor coils. Mechanical separation is achieved through a wire structure. Publication number CN116500372B is titled "Automatic Electrical Inspection Equipment and Method for Flat Wire Motor Coils." The wire structure includes a wire pulley, a wire pulley shaft, a mounting base, and a wire drive structure. The wire pulley has a spiral tooth structure with transition structures at the inlet and outlet ports, allowing 3D hairpin coils to be introduced into and out of the spiral structure, respectively. During rotation, the 3D hairpin coils can be separated one by one. A wire pulley detection sensor for detecting the wire pulley's rotational speed is located directly above the wire pulley. Although the wire pulley can separate the flat wire motor coils, the narrow width of the flat wire motor coils results in a small gap between the coils passing through the wire pulley. Furthermore, the wire pulley detection sensor for detecting the wire pulley's rotational speed also has a certain response gap. During the wire pulley's winding process, two or more flat wire motor coils can easily be simultaneously discharged from the end of the wire pulley, causing material accumulation at the next workstation. This results in low reliability and stability, making it difficult to accurately separate the flat wire motor coils. Therefore, improvements are necessary. Summary of the Invention

[0004] The purpose of the present invention is to provide a device and method for arranging flat wire motor coils for new energy vehicles that effectively reduces manual labor, improves the efficiency of the arrangement of flat wire motor coils, avoids confusion in the installation positions of flat wire motor coils, and at the same time solves the problem of low reliability and stability of existing mechanical arrangement and inability to accurately arrange flat wire motor coils.

[0005] The technical solution of the present invention is: A material distribution and arrangement device for flat wire motor coils of new energy vehicles includes a frame, a storage rack, a pushing assembly, an intermittent feeding assembly, a guide wedge and a traction assembly, and is characterized in that: a plurality of storage racks are fixedly installed in parallel on the frame, a pushing assembly is installed across the line on the storage rack, and an intermittent feeding assembly is installed at one end of the storage rack. When the intermittent feeding assembly pushes the flat wire motor coil forward, it first separates the adjacent flat wire motor coils in sequence to form a separation gap, and then gradually generates a certain height difference between the adjacent flat wire motor coils while enlarging the spacing of the gaps between the flat wire motor coils, so that the flat wire motor coil is only distributed one flat wire motor coil at a time in one distribution beat of the intermittent feeding assembly, thereby realizing precise distribution of the flat wire motor coil, and a guide wedge is installed on the frame corresponding to the front end of the intermittent feeding assembly through the bottom plate, and a traction assembly is installed on the bottom plate on one side of the guide wedge.

[0006] The storage rack includes storage vertical plates and horizontal plates. The storage vertical plates are long rectangular plates. The storage vertical plates are arranged at intervals. Multiple horizontal plates are fixedly installed between the storage vertical plates. One end of the horizontal plate extends to the outside of the vertical plate. The horizontal plate extended to the outside of the vertical plate is fixedly connected to the frame. A guide plate is fixedly installed at one end of the storage vertical plate.

[0007] The guide plate has a triangular cross section, and the triangular tip of the guide plate is round.

[0008] The pushing assembly includes a support frame, a screw motor and a transmission screw. The support frames are arranged at intervals, and a transmission screw is movably installed between the support frames. A screw nut is threadedly installed on the transmission screw. A slide is fixed between the support frames above the transmission screw. The slide and the screw nut are slidably connected. The support frame above the slide is equipped with a screw motor. The transmission shaft of the screw motor and one end of the transmission screw are connected through a pulley and a transmission belt. A pushing clamp is installed under the screw nut.

[0009] The pushing clamp comprises a clamping claw cylinder and a pushing claw. The pushing claw is fixedly mounted on the clamping claw of the clamping claw cylinder. The pushing claw is a long rectangular body, and a pushing protrusion is arranged on the inner side of the pushing claw.

[0010] The intermittent feeding assembly includes an assembly plate, a rotating motor and a separating rotating head. The assembly plate is fixedly installed between the material storage vertical plates, the rotating motor is installed on the assembly plate, and the separating rotating head is fixedly installed on the transmission shaft of the rotating motor. The separating rotating head is in the shape of a variable diameter cylinder. A first thread groove is provided on the circumference of the fine diameter area of ​​the separating rotating head, and a second thread groove is provided on the circumference of the coarse diameter area of ​​the separating rotating head. A chamfer is provided between the coarse diameter area and the fine diameter area of ​​the separating rotating head. The chamfer facilitates the flat wire motor coil to climb from the fine diameter area to the coarse diameter area, so that a certain height difference is formed between the two adjacent flat wire motor coils. The first thread groove and the second thread groove are smoothly connected, and the flat wire motor coil can slide from the first thread groove to the second thread groove. The pitch of the second thread groove is greater than that of the first thread groove. The variable diameter cylindrical separating rotating head can increase the spacing between the two adjacent flat wire motor coils in the second thread groove to avoid mutual interference and jamming between the two flat wire motor coils.

[0011] The guide wedge is a right-angled triangle, which is fixedly mounted on the base plate. A clearance groove is provided on the inclined surface of the guide wedge. A first limit plate is provided on the base plate on one side of the guide wedge, and a second limit plate is provided on the base plate on the other side of the guide wedge. A baffle is provided on the base plate at the front end of the first limit plate and the second limit plate, and a baffle is provided on the inside of the baffle. A limit block is provided on the base plate between the baffle and the first limit plate, and a clearance groove is provided between the limit block and the first limit plate and the baffle. An auxiliary limit strip is provided on the baffle adjacent to the second limit plate.

[0012] The traction assembly includes a rodless cylinder and a traction column. The rodless cylinder is fixedly mounted on the base plate. The traction column is fixedly mounted on the piston of the rodless cylinder. The traction column is cylindrical. A giveway chute is provided on the base plate corresponding to the traction column. The traction column passes through the giveway chute and extends to the outside of the giveway chute. The traction column extending to the outside of the giveway chute corresponds to the giveway groove of the guide wedge block.

[0013] Based on the above-mentioned material distribution and arrangement device for the flat wire motor coil of new energy vehicles, the material distribution method includes the following steps: S1. Mount multiple flat wire motor coil assemblies on a storage rack, and then push the multiple flat wire motor coil assemblies to the storage rack in front of the pushing component; S2. The flat wire motor coil at the end is pushed by the pushing component, and the flat wire motor coil group as a whole moves forward along the storage rack; S3. When the flat wire motor coil enters the intermittent feeding assembly from the storage rack, the intermittent feeding assembly forms a certain separation gap between two adjacent flat wire motor coils. As the flat wire motor coil continues to move forward, the intermittent feeding assembly gradually forms a certain height difference between two adjacent flat wire motor coils while widening the spacing of the gaps between the flat wire motor coils. In this way, in the feeding cycle of the intermittent feeding assembly, only one flat wire motor coil is fed at a time, thereby achieving accurate feeding of the flat wire motor coils. S4. The flat wire motor coil fed from the intermittent feeding assembly is guided by the guide wedge and changes from a vertical posture to a horizontal posture. The flat wire motor coil lies flat on the bottom plate, and is pulled to a specified position by the traction assembly.

[0014] The beneficial effects of the present invention compared with the prior art are: The material distribution and arrangement device of the flat wire motor coil of the new energy vehicle forms a mounting for the flat wire motor coil through multiple storage racks, and uses the pushing claws of the pushing clamp to push the multiple flat wire motor coils forward along the storage vertical plate respectively. When the flat wire motor coil at the front end of the flat wire motor coil group enters the circumference of the fine diameter area of ​​the separating rotating head from the storage vertical plate, the first thread groove on the circumference of the fine diameter area engages with the arc-shaped recess at the top of the flat wire motor coil, and each rotating motor is started. The transmission shaft of the rotating motor drives the separating rotating head to rotate. When the separating rotating head rotates, the first thread groove and the second thread groove of the separating rotating head rotate synchronously. At this time, under the rotation action of the first thread groove, the rotational motion of the first thread groove is converted into linear motion of the flat wire motor coil, so that the first thread groove pushes the flat wire motor coil to move forward in the axial direction. As the pushing clamp continuously pushes the flat wire motor coil into the fine diameter area of ​​the separating rotating head, the first thread groove of the separating rotating head can separate the flat wire motor coils in sequence to ensure the order of pushing the flat wire motor coils. Since a chamfer is provided on the circumference between the coarse diameter area and the fine diameter area of ​​the separating rotating head, when the flat wire motor coil climbs from the first thread groove in the fine diameter area to the second thread groove in the coarse diameter area through the chamfer transition, a certain height difference will be formed between the flat wire motor coils that have climbed and the flat wire motor coils that have not climbed. This height difference can effectively avoid the mutual interference between the two adjacent flat wire motor coils, resulting in the problem of the separating rotating head simultaneously dividing two adjacent flat wire motor coils, thereby achieving accurate dividing of one flat wire motor coil each time. The flat wire motor coils separated from the separating rotating head are guided by the inclined surface of the guide wedge and limited by the base plate and the first and second limit plates, so that the vertical posture of the flat wire motor coils is adjusted to a horizontal posture. The flat wire motor coils lie flat on the base plate. The piston of the rodless cylinder can drive the traction column to move from the guide wedge's clearance groove toward the stop block, so that the traction column contacts the arc-shaped concave at the top of the flat wire motor coil. The traction column pulls the flat wire motor coils until they contact the stop block, which limits the flat wire motor coils. At this time, each flat wire motor coil is pulled to the designated position, thereby completing the entire operation of sorting and arranging each flat wire motor coil. The sorting and arranging device for flat wire motor coils for new energy vehicles effectively reduces manual labor and improves the efficiency of sorting and arranging flat wire motor coils. At the same time, it solves the problem that individual differences in the staff can cause confusion among the flat wire motor coils, resulting in incorrect arrangement of the flat wire motor coils, which affects the motor yield rate, and the reliability and stability of the existing mechanical sorting process are low, and the flat wire motor coils cannot be accurately sorted.

[0017] As attached Figure 1-7 shown The material distribution and arrangement device of the flat wire motor coil of the new energy vehicle includes a frame 1, a storage rack, a pushing assembly, an intermittent feeding assembly, a guide wedge 2 and a traction assembly. A plurality of storage racks are fixedly installed on the frame 1, and the storage rack includes two storage vertical plates 3 and a cross plate 4. The storage vertical plates 3 are long rectangular plates. The two storage vertical plates 3 are arranged at intervals. A plurality of cross plates 4 are fixedly installed between the two storage vertical plates 3. One end of the cross plate 4 extends to the outside of the vertical plate. The cross plate 4 extending to the outside of the vertical plate is fixedly connected to the frame 1. A guide plate 5 is fixedly installed at one end of the storage vertical plate 3. The guide plate 5 has a triangular cross-section and the triangular tip of the guide plate 5 is round. When working, a plurality of flat wire motor coils 30 can be mounted through the two storage vertical plates 3, so that the flat wire motor coils 30 can be stored on the storage vertical plates 3 of the storage rack, and the flat wire motor coils 30 can be conveniently guided to the storage vertical plates 3 of the storage rack through the guide plate 5.

[0018] A pushing assembly is installed across the line on the storage rack, and the pushing assembly includes a support frame 6, a screw motor 7 and a transmission screw 8. The support frames 6 are fixedly installed on the frame 1 at intervals, and a transmission screw 8 is movably installed between the support frames 6 through bearings. A screw nut 9 is threadedly installed on the transmission screw 8, and a slide 10 is fixedly installed between the support frames 6 above the transmission screw 8. The slide 10 is slidably connected with the screw nut 9, and the slide 10 forms a circumferential limit for the screw nut 9. A screw motor 7 is fixedly installed on the support frame 6 above the slide 10, and the transmission shaft of the screw motor 7 and one end of the transmission screw 8 are connected through a pulley and a transmission belt 11. When working, the transmission shaft of the screw motor 7 can drive the transmission screw 8 to rotate through the pulley and the transmission belt 11.

[0019] A pushing clamp is fixedly installed under the screw nut 9, and the pushing clamp includes a clamping claw cylinder 12 and a pushing claw 13. The clamping claw cylinder 12 is a commercially available part, and the two clamping claws of the clamping claw cylinder 12 can move in relative or opposite directions. A pushing claw 13 is fixedly installed on the clamping claw of the clamping claw cylinder 12, and the pushing claw 13 is a long rectangular body. A pushing protrusion 14 is provided on the inner side of the pushing claw 13. When working, the two pushing claws 13 are driven by the clamping claws of the clamping claw cylinder 12 to move in relative or opposite directions. After the pushing claws 13 move into place in opposite directions, it is convenient to manually move multiple flat wire motor coils 30 along the storage rack to the front of the pushing claws 13. After the pushing claws 13 move into place in relative directions, the pushing protrusion 14 of the pushing claws 13 forms a limit on the flat wire motor coil 30 at the end of the storage rack, thereby pushing the multiple flat wire motor coils 30 on the storage rack to move forward synchronously.

[0020] An intermittent feeding assembly is installed at one end of the storage rack, and the intermittent feeding assembly includes an assembly plate 15, a rotating motor 16 and a separating rotating head 17. The assembly plate 15 is fixedly installed between the storage vertical plates 3, and the rotating motor 16 is fixedly installed on the assembly plate 15. The separating rotating head 17 is fixedly installed on the transmission shaft of the rotating motor 16. The separating rotating head 17 is a variable diameter cylindrical head. A first thread groove 18 is provided on the circumference of the fine diameter area of ​​the separating rotating head 17, and a second thread groove 19 is provided on the circumference of the coarse diameter area of ​​the separating rotating head 17. The first thread groove 18 and the second thread groove 19 serve as conveying channels for the flat wire motor coil 30. When working, the first thread groove 18 of the intermittent feeding assembly forms a separation gap between two adjacent flat wire motor coils 30, and a height difference is formed between the first thread groove 18 and the second thread groove 19 between two adjacent flat wire motor coils 30. The second thread groove 19 can enlarge the gap spacing between two adjacent flat wire motor coils 30.

[0021] A chamfer is provided on the circumference separating the thick-diameter area and the thin-diameter area of the separating rotary head 17. The purpose of this setting is as follows: The chamfer facilitates the transition and climbing of the flat wire motor coil 30 from the thin-diameter area to the thick-diameter area. When the flat wire motor coil 30 transitions and climbs from the thin-diameter area to the thick-diameter area, a certain height difference will be formed between two adjacent flat wire motor coils 30 after climbing and those before climbing. This height difference can effectively prevent the problem that the separating rotary head 17 simultaneously distributes materials to two adjacent flat wire motor coils 30 due to mutual interference between the adjacent flat wire motor coils 30.

[0022] The first thread groove 18 and the second thread groove 19 are smoothly connected. The purpose of this setting is as follows: The flat wire motor coil 30 can smoothly slide from the first thread groove 18 into the second thread groove 19.

[0023] The pitch of the second thread groove 19 is greater than that of the first thread groove 18. The separating rotary head 17 with a variable-diameter cylindrical shape can increase the distance between two adjacent flat wire motor coils 30, one located in the second thread groove 19 and the other located in the first thread groove 18, further preventing problems such as mutual interference, jamming, and stacking of materials between the adjacent flat wire motor coils 30. Combining with the height difference generated by the above-mentioned variable-diameter separating rotary head 17 on the flat wire motor coil 30, it effectively ensures that in one feeding cycle of the separating rotary head 17 for the flat wire motor coil 30, only one flat wire motor coil 30 is fed each time, achieving precise feeding of the flat wire motor coil 30.

[0024] A guiding wedge 2 is installed on the frame 1 corresponding to the front end of the intermittent feeding component through a bottom plate 20. The guiding wedge 2 is a right-angled triangular prism and is fixedly installed on the bottom plate 20. During operation, the function of the guiding wedge 2 is to guide the flat wire motor coil 30 to move obliquely downward. Through the cooperation of the guiding wedge 2 and the bottom plate 20, the vertical posture of the flat wire motor coil 30 is adjusted to a horizontal posture, making the flat wire motor coil 30 lie flat on the bottom plate 20.

[0025] A first limiting plate 21 is fixedly installed on the bottom plate 20 on one side of the guiding wedge 2, and a second limiting plate 22 is fixedly installed on the bottom plate 20 on the other side of the guiding wedge 2. A baffle 23 is provided on the bottom plate 20 at the front ends of the first limiting plate 21 and the second limiting plate 22. The baffle 23 is in a "冂" shape. A stop block 24 is fixedly installed on the bottom plate 20 inside the baffle 23. A limiting block 25 is fixedly installed on the bottom plate 20 between the baffle 23 and the first limiting plate 21. A relief groove 26 is provided between the limiting block 25 and the first limiting plate 21 and the baffle 23. The purpose of this setting is as follows: The relief groove 26 facilitates the taking of the flat wire motor coil 30 from the bottom plate 20. An auxiliary limiting strip 31 is fixedly installed on the baffle 23 near the second limiting plate 22, and the auxiliary limiting strip 31 plays an auxiliary limiting role for the flat wire motor coil 30.

[0026] A yield groove 26 is provided on the inclined surface of the guide wedge 2. A traction assembly is installed on the bottom plate 20 on one side of the guide wedge 2. The traction assembly includes a rodless cylinder 27 and a traction column 28. The rodless cylinder 27 is fixedly mounted on the bottom plate 20. A traction column 28 is fixedly mounted on the piston of the rodless cylinder 27. The traction column 28 is cylindrical. A yield groove 29 is provided on the bottom plate 20 corresponding to the traction column 28. The traction column 28 passes through the yield groove 29 and extends to the outside of the yield groove 29. The traction column 28 extending to the outside of the give way slot 29 corresponds to the give way slot 26 of the guide wedge 2. During operation, the give way slot 26 of the guide wedge 2 can accommodate the traction column 28. When the flat wire motor coil 30 slides onto the bottom plate 20 at the front end of the traction column 28, the piston of the rodless cylinder 27 can drive the traction column 28 to move from the give way slot 26 of the guide wedge 2 toward the stop block 24, thereby pulling the flat wire motor coil 30 to the position of the stop block 24 through the traction column 28.

[0027] After the loading of the plurality of flat wire motor coils 30 is completed, the plurality of flat wire motor coils 30 are respectively pushed forward along the storage vertical plate 3 to the front of the pushing clamp, and the clamping claw cylinder 12 of each pushing clamp is controlled to drive the pushing claw 13 to move closer to each other until the pushing protrusion 14 of the pushing claw 13 corresponds to the flat wire motor coil 30 at the end, and the pushing claw 13 stops moving, and each screw motor 7 is started. The transmission shaft of the screw motor 7 can drive the transmission screw 8 to rotate through the pulley and the transmission belt 11, thereby driving the pushing clamp to move forward through the transmission screw 8. When the pushing clamp moves forward, the pushing protrusion 14 of the pushing clamp pushes the flat wire motor coil 30 groups to move forward along the storage vertical plate 3.

[0028] When the flat wire motor coil 30 at the front end of the flat wire motor coil 30 group enters the circumference of the thin diameter area of ​​the separating rotating head 17 from the material storage vertical plate 3, the first thread groove 18 on the circumference of the thin diameter area engages with the arc-shaped recess at the top of the flat wire motor coil 30, starting each rotating motor 16. The transmission shaft of the rotating motor 16 drives the separating rotating head 17 to rotate. When the separating rotating head 17 rotates, the first thread groove 18 and the second thread groove 19 of the separating rotating head 17 rotate synchronously. At this time, under the rotation action of the first thread groove 18, the rotational motion of the first thread groove 18 is converted into a linear motion of the flat wire motor coil 30, so that the first thread groove 18 pushes the flat wire motor coil 30 to move forward in the axial direction. As the pushing clamp continuously pushes the flat wire motor coil 30 into the thin diameter area of ​​the separating rotating head 17, the first thread groove 18 of the separating rotating head 17 can separate the two adjacent flat wire motor coils 30 in sequence to form a separation gap, thereby ensuring the order of pushing the flat wire motor coil 30.

[0029] Since a chamfer is provided on the circumference separating the coarse-diameter area and the fine-diameter area of ​​the rotating head 17, when the flat wire motor coil 30 climbs from the first thread groove 18 in the fine-diameter area to the second thread groove 19 in the coarse-diameter area through the chamfer transition, a certain height difference will be formed between the flat wire motor coil 30 that has climbed and the adjacent flat wire motor coils 30 that have not climbed. This height difference can effectively prevent mutual interference between the two adjacent flat wire motor coils 30.

[0030] While the separating rotating head 17 pushes the flat wire motor coil forward, the second thread groove 19 effectively widens the spacing between two adjacent flat wire motor coils, so that the flat wire motor coil can be separated one flat wire motor coil at a time in one dividing cycle of the intermittent feeding assembly, thereby realizing accurate dividing of the flat wire motor coil.

[0031] The flat wire motor coil 30 that is distributed from the separating rotating head 17 is guided by the inclined surface of the guide wedge 2 and limited by the base plate 20 and the first limit plate 21 and the second limit plate 22, so that the vertical posture of the flat wire motor coil 30 is adjusted to a horizontal posture. The flat wire motor coil 30 lies flat on the base plate 20, and the piston of the rodless cylinder 27 can drive the traction column 28 to move from the yield groove 26 of the guide wedge 2 toward the stop block 24, so that the traction column 28 contacts the arc-shaped concave at the top of the flat wire motor coil 30, and the traction column 28 pulls the flat wire motor coil 30 to contact with the stop block 24. The stop block 24 forms a limit on the flat wire motor coil 30. At this time, each flat wire motor coil 30 is pulled to the specified position, thereby completing the entire operation of distributing and arranging each flat wire motor coil 30 at one time.
