Description

Technical Field

[0001] The present invention belongs to the technical field of stator wire insertion, and specifically relates to an automatic stator wire insertion device for automotive generators. Background Art

[0002] As one of the most important means of transportation in modern society, the automotive industry has been expanding in scale and continuously upgrading in technology. Automotive generators, as key components of automotive electrical systems, provide power for various electronic devices in vehicles and charge the vehicle batteries. With the increasing degree of automotive electrification, higher requirements are put forward for the performance, reliability, and production efficiency of automotive generators. In recent years, the production volume of automobiles has shown a steady growth trend, especially the rapid rise of new energy vehicles, which has further driven the development of the automotive generator market.

[0003] In the early production of automotive generators, stator wire insertion was mainly completed manually. Workers needed to insert enameled wires into the slots of the stator core one by one; with the development of technology, some mechanical wire insertion devices, such as stator wire insertion machines, emerged.

[0004] A stator wire insertion machine is a device used to insert winding coils into the slots of the stator core of an electric motor. The stator wire insertion machine embeds the coils into the slots of the stator core according to certain rules and sequences through mechanical transmission and electrical control. Usually, the device will first arrange the coils into appropriate shapes and sizes, then fix the stator core using a fixture, and then insert the coils into the slots one by one or in groups through a wire insertion mechanism.

[0005] When using a stator wire insertion machine to insert wires into the stator, first hang multiple wound coils on the wire insertion rack in sequence. After all the coils are hung on the wire insertion rack, use a wire pushing device to push the coils into the wire slots of the stator, thus completing the wire insertion work for the stator.

[0006] However, after the wound coils are hung on the wire insertion rack, due to the certain tension existing in the coils themselves, the coils are prone to strand separation. When the coils experience strand separation, the strands on the entire coil will become loose. Since the wires of the loose coils have disordered orientations and cannot form a regular shape, they are likely to tangle and squeeze each other when passing through the wire slots, resulting in the wire harness being unable to pass through the stator slots smoothly, increasing the difficulty of wire insertion and reducing work efficiency. Summary of the Invention

[0007] To make up for the deficiencies of the prior art and solve the above technical problems, the present invention proposes an automatic stator wire insertion device for automotive generators.

[0018] Tooth grooves are uniformly arranged on the outer circle surface of the C-shaped ring; a gear is rotatably connected in each installation block, and the gear meshes with the tooth grooves; the gear is driven by a motor.

[0019] Preferably, the cross-section of the C-shaped ring is semi-circular; a smooth rubber layer is fixedly connected to the inner circle surface of the C-shaped ring.

[0020] Preferably, a guide plate is provided on one side of each of the columns away from the fixed cylinder;

[0030] The beneficial effects of the present invention are as follows:

[0031] 1. For the automatic wire embedding device for the stator of an automotive generator described in the present invention, by using a C-shaped ring to hold the coil hanging on the wire embedding frame, the coil can be kept in a straightened state. At the same time, when the push rod pushes the coil upward, the C-shaped ring will move upward while holding the straightened coil, so as to ensure that the coil is in a straightened state during the process of gradually being embedded into the stator wire groove, thus avoiding the situation that the coil is scattered due to tension, which may cause the coil to be entangled. At the same time, when the loose coil is gradually pushed into the wire groove, the wire groove will squeeze the loose wire strands so that they can penetrate into the wire groove, which will increase the friction between the coil and the wire groove, and at the same time increase the difficulty of wire embedding and reduce the work efficiency.

[0032] 2. In the process of the column moving towards the fixed cylinder in the automatic wire embedding device for the stator of an automotive generator according to the present invention, it will drive the mounting block and the C-shaped ring to move towards the fixed cylinder side. At the same time, the C-shaped ring will drive the hooked coil to move towards the fixed cylinder side. After the coil moves towards the fixed cylinder side, the coil can be gradually moved to the position below the stator at this time, thereby reducing the angle between the straightened coil and the wire groove, reducing the friction force when the coil enters the wire groove, and making it easier for the coil to penetrate into the wire groove.

[0033] 3. In the automatic wire embedding device for the stator of an automotive generator according to the present invention, since the column is engaged in the slider by threads, when it is necessary to adjust the height of the C-shaped ring according to the length of the coil, the column can be rotated at this time. When the column rotates, the threads on the column will engage with the thread grooves on the slider, thereby driving the column to move up or down. The column moving up or down will also drive the mounting block and the C-shaped ring to move up or down, thereby adjusting the height of the C-shaped ring, avoiding that after the coil is hung on the C-shaped ring, due to the excessive height of the C-shaped ring, the coil cannot be straightened, resulting in the coil still being in a loose state.

Detailed implementation manners

[0047] In order to make the technical means, creative features, achieving purposes and functions implemented by the present invention easy to understand, the present invention will be further described below in conjunction with specific implementation manners.

[0048] Embodiment 1:

[0049] As Figures 1 to 11 shown, an automatic wire embedding device for an automotive generator stator according to the present invention includes a stator wire embedding machine; the stator wire embedding machine includes a machine body 1; an inclined workbench 11 is provided on the machine body 1;

[0050] A fixed cylinder 12 is fixedly installed on the workbench 11; a wire embedding frame is installed inside the fixed cylinder 12, and the wire embedding frame is used to hang the wound coil 161;

[0051] The wire embedding frame is combined into a circle by a plurality of first vertical rods 13, and there is a gap between adjacent first vertical rods 13; the tops of the plurality of first vertical rods 13 are fixedly connected with second vertical rods 14, and the second vertical rods 14 also enclose a circle, and the diameter of the circle enclosed by the second vertical rods 14 is smaller than the diameter of the circle enclosed by the first vertical rods 13;

[0052] The circle enclosed by the second vertical rods 14 is used to sleeved the stator 15, and the wire grooves 16 opened in the inner circle of the stator 15 are arranged in an alternating manner with the first vertical rods 13 and the second vertical rods 14;

[0053] A hydraulic cylinder 17 is installed inside the machine body 1; a push plate 18 is fixedly connected to the hydraulic cylinder 17; uniformly arranged push rods 19 are fixedly connected to the top end face of the push plate 18, and the push rods 19 extend above the fixed cylinder 12 and are located in the gaps between adjacent first vertical rods 13;

[0054] Above the fixed cylinder 12, clamping plates 111 are installed on both sides of the workbench 11, and the clamping plates 111 are driven by a hydraulic mechanism; multiple traction components are installed on the workbench surface, and the traction components are used to traction the wound coil 161;

[0055] In this embodiment, a driven disk 2 is fixedly connected to the outer ring of the push disk 18;

[0056] Multiple traction components each include a column 21; multiple columns 21 are all installed on the driven disk 2 and form a circle; multiple columns 21 all extend to the workbench 11 and are slidably connected to the workbench 11;

[0057] A cylindrical groove is formed in each column 21; a pull rod 22 is slidably connected in each cylindrical groove, and the pull rod 22 extends above the workbench 11; a elastic band 23 is fixedly connected to the bottom of the pull rod 22, and the other side of the elastic band 23 is fixedly connected in the cylindrical groove;

[0058] An installation block 24 is fixedly connected to the top of each pull rod 22; an arc-shaped groove is formed in the inner wall of each installation block 24; a C-shaped ring 25 is slidably connected in each arc-shaped groove, and the opening of the C-shaped ring 25 faces downward in the initial state;

[0059] Tooth grooves 26 are evenly arranged on the outer ring surface of the C-shaped ring 25; a gear 27 is rotatably connected in each installation block 24, and the gear 27 meshes with the tooth grooves 26; the gear 27 is driven by a motor 28;

[0060] In this embodiment, the cross-section of the C-shaped ring 25 is semi-circular; a smooth rubber layer is fixedly connected to the inner ring surface of the C-shaped ring 25;

[0061] Specifically, when winding the stator 15, first hang the wound coils 161 on different first vertical rods 13 of the winding rack in sequence. The specific operation is as follows. First, hang the coil 161 on the second vertical rod 14, and then push the coil 161 downward. The coil 161 will move downward to the second vertical rod 14. When the top of the push rod 19 between the coil 161 and the adjacent first vertical rod 13 touches, stop pushing the coil 161 downward. Then, pull the C-ring 25 upward. The C-ring 25 will drive the mounting block 24 and the pull rod 22 to move upward, and the pull rod 22 will move upward in the cylindrical groove of the column 21 and gradually stretch the elastic band 23. Then, hang the other end of the coil 161 hanging on the first vertical rod 13 on the C-ring 25 and release the C-ring 25. When the C-ring 25 is released, under the pulling force of the elastic band 23, it will pull the pull rod 22 to move downward in the cylindrical groove, and at the same time drive the mounting block 24 and the C-ring 25 to move downward. The downward moving C-ring 25 will pull the coil 161 to move downward, thereby gradually straightening the coil 161. When the coil 161 is straightened, at this time the C-ring 25 no longer moves downward, and at the same time the coil 161 is in a straightened state and the coil 161 will not be scattered. Then, repeat the above operations in sequence and hang the other sides of the coils 161 at different positions on the adjacent C-rings 25, and then the winding work can be carried out;

[0062] More specifically, when all the coils 161 are hung on the winding rack, at this time the staff sleeved the stator 15 on the circle formed by the second vertical rods 14. The bottom of the stator 15 is in contact with the top end face of the first vertical rod 13. At the same time, the coils 161 on the stator 15 correspond to the push rods 19 one by one. Then, control the clamping plate 111 to work. The hydraulic mechanism will drive the clamping plate 111 to rotate to the top of the stator 15 and fix the top position of the stator 15. Then, control the hydraulic cylinder 17 to gradually extend, which will drive the push plate 18 to gradually move upward. During the process of the push plate 18 gradually moving upward, it will drive multiple push rods 19 to gradually move upward along the gaps between the adjacent first vertical rods 13, thereby gradually pushing the coils 161 hung on the winding rack to gradually move upward. Since the driven disk 2 is fixedly connected to the push plate 18, the driven disk 2 will move upward following the push plate 18. The upward moving push plate 18 will drive multiple columns 21 to move upward together. Since the push rods 19 and the columns 21 both move upward following the push plate 18 at the same time, when the push rod 19 pushes the coil 161 to move upward along the first vertical rod 13, at this time the C-ring 25 and the mounting block 24 will also move upward following the coil 161, so that the coil 161 can always be pulled by the C-ring 25 and be in a taut state during the process of being pushed upward, thus avoiding the situation of the coil 161 becoming loose;

[0063] Furthermore, in the process of the push rod 19 pushing the coil 161 upward, the push rod 19 will gradually push the coil 161 into the wire slot 16 opened on the stator 15, and the coil 161 located below the stator 15 will gradually enter the wire slot 16 of the stator 15. At the same time, the C-shaped ring 25 will gradually approach the bottom position of the stator 15. When the push rod 19 pushes the coil 161 out of the top of the wire slot 16 on the stator 15, the coil 161 is embedded in the wire slot 16 of the stator 15, and the hydraulic cylinder 17 no longer extends. At the same time, the control motor 28 rotates, and the rotating motor 28 drives the gear 27 to rotate. Since the gear 27 and the C-shaped ring The tooth grooves 26 on the C-shaped ring 25 are meshed, thereby driving the C-shaped ring 25 to rotate. When the opening of the C-shaped ring 25 gradually rotates to the upper side, the coil 161 hung on the C-shaped ring 25 will be separated from the C-shaped ring 25. When the coil 161 is separated from the C-shaped ring 25, the C-shaped ring 25 will slide into the cylindrical groove under the action of the elastic band 23, and then the hydraulic cylinder 17 is controlled to shrink to the initial state. The hydraulic cylinder 17 will drive the push plate 18, the push rod 19, the driven plate 2 and the column 21 to gradually restore to the initial state, and then the stator 15 with completed wire embedding can be removed from the second column 14, and then the next stator 15 can be embedded;

[0064] Furthermore, since the cross section of the C-shaped ring 25 is semicircular, when the coil 161 is hung on the C-shaped ring 25, the contact position between the coil 161 and the C-shaped ring 25 can be limited to an arc, thereby preventing the coil 161 from being bent into a rectangle when being pulled by the C-shaped ring 25. At the same time, since the inner ring of the C-shaped ring 25 is fixedly connected with a smooth rubber layer, the C-shaped ring 25 can be prevented from scratching the coil 161, thereby preventing the coil 161 from being damaged.

[0065] By using the C-shaped ring 25 to hold the coil 161 hung on the wire embedding frame, the coil 161 can be kept in a stretched state. At the same time, when the push rod 19 pushes the coil 161 upward, the C-shaped ring 25 will hold the stretched coil 161 while moving upward, thereby ensuring that the coil 161 is in a stretched state while being gradually embedded in the wire slot 16 of the stator 15, thereby preventing the coil 161 from becoming loose due to tension, which will cause the coil 161 to become entangled. At the same time, when the loose coil 161 is gradually pushed into the wire slot 16, the wire slot 16 will squeeze the loose wire strands before they can be inserted into the wire slot 16, thereby increasing the friction between the coil 161 and the wire slot 16, and at the same time increasing the difficulty of embedding the wire and reducing work efficiency.

[0066] Embodiment 2:

[0067] A guide plate 3 is provided on one side of each of the upright posts 21 away from the fixed cylinder 12;

[0068] The top end face of the guide plate 3 is an inclined plane; a chute 31 is provided on the workbench 11 at the top of the guide rod 36, and the guide plate 3 slides within the chute 31;

[0069] An oblong slot 32 is provided on the workbench 11, and the column 21 slides within the oblong slot 32, and the oblong slot 32 communicates with the chute 31; a limiting roller 33 is installed on the workbench 11 above the chute 31;

[0070] Uniformly arranged slideways 34 are provided on the driven disk 2; sliders 35 are slidably connected within the slideways 34; the bottom of the column 21 is installed on the slider 35;

[0071] The slider 35 and the slideway 34 are connected by a spring;

[0072] In this embodiment, the limiting roller 33 is a rotating roller and is rotatably installed on the workbench 11 through a side plate;

[0073] Specifically, since a guide plate 3 is installed on the side of the column 21 away from the fixed cylinder 12 and the top of the guide plate 3 is an inclined plane, when the driven disk 2 drives the column 21 to move upward, it will also drive the guide plate 3 to move upward along the chute 31. When the guide plate 3 moves upward, the inclined plane on the guide plate 3 will first contact the limiting roller 33. As the guide plate 3 continues to move upward, under the limitation of the limiting roller 33, it will push the guide plate 3 to move towards the fixed cylinder 12 side, and at the same time will drive the column 21 to move towards the fixed cylinder 12 side within the oblong slot 32. During the movement of the column 21, it will push the slider 35 to slide within the slideway 34 and compress the spring connecting the slider 35;

[0074] More specifically, during the process of the column 21 moving towards the fixed cylinder 12 side, it will drive the mounting block 24 and the C-shaped ring 25 to move towards the fixed cylinder 12 side. At the same time, the C-shaped ring 25 will drive the hooked coil 161 to move towards the fixed cylinder 12 side. When the coil 161 moves towards the fixed cylinder 12 side, at this time, the coil 161 can be gradually moved to the position below the stator 15, thereby reducing the included angle between the straightened coil 161 and the wire groove 16, thus reducing the friction when the coil 161 enters the wire groove 16 and enabling the coil 161 to penetrate into the wire groove 16 more easily;

[0075] Further, when the coil 161 penetrates into the wire groove 16 and the column 21 gradually moves down to the initial state, when the guide plate 3 moves down to the limiting position of the limiting roller 33, at this time, the slider 35 will return to the initial state within the slideway 34 under the action of the spring, thereby driving the column 21 and the guide plate 3 to return to the initial state;

[0076] Furthermore, since the limiting roller 33 is a rotating roller, when the guide plate 3 moves along the limiting roller 33, the limiting roller 33 will rotate along the guide plate 3. During this process, the friction between the limiting roller 33 and the guide plate 3 can be reduced.

[0077] Embodiment Three:

[0078] The column 21 passes through the slider 35;

[0079] On one side where the column 21 passes through the slider 35, threads are provided; in the inner wall of the slider 35, a thread groove is provided, and the column 21 is threadedly engaged with the slider 35;

[0080] In this embodiment, the guide plate 3 is fixed on the slider 35 and does not contact the column 21;

[0081] In this embodiment, a guide rod 36 is slidably connected to the driven disk 2, and one side of the guide rod 36 is installed at the bottom of the workbench 11, and the other side is installed in the machine body 1;

[0082] Specifically, since the column 21 is threadedly engaged in the slider 35, when it is necessary to adjust the height of the C-shaped ring 25 according to the length of the coil 161, the column 21 can be rotated at this time. When the column 21 rotates, the threads on the column 21 will be engaged with the thread groove on the slider 35, thereby driving the column 21 to move upward or downward. The upward or downward moving column 21 will also drive the mounting block 24 and the C-shaped ring 25 to move upward or downward, so that the height of the C-shaped ring 25 can be adjusted, avoiding the situation that after the coil 161 is hung on the C-shaped ring 25, due to the too high height of the C-shaped ring 25, the coil 161 cannot be straightened, resulting in the coil 161 still being in a loose state;

[0083] More specifically, since the guide plate 3 is fixedly connected to the slider 35, when the position of the column 21 is adjusted, the position of the guide plate 3 remains unchanged at this time, thereby preventing the guide plate 3 from contacting the limiting roller 33 after moving upward with the column 21 and being blocked by the limiting roller 33 and unable to maintain its initial state; since the guide rod 36 is slid on the driven disk 2, when the driven disk 2 moves, it will move along the guide rod 36, thereby limiting the driven disk 2 and avoiding the situation of the driven disk 2 shaking.
