The rotating stator cuts the magnetic lines of force to generate alternating current in the stator coil. In order to ensure the working efficiency of the stator coil, the stator coil needs to be wound by a winding machine.

[0003] There are many winding machines in the prior art, among which the flying fork winding machine realizes coil winding through the rotational movement of the flying fork mechanism.

Specific embodiments

[0021] In order to make the technical means, creative features, achieved purposes and effects of the present invention easy to understand, the present invention will be further described below in conjunction with specific embodiments.

[0022] Such as Figure 1 、 Figure 4 and Figure 8As shown in the figure, a winding device for an automotive generator stator coil according to an embodiment of the present invention includes a workbench 1; a support plate 2 is fixedly connected to the top surface of the workbench 1; a rotating seat 3 is rotatably connected to the surface of the support plate 2, and the rotating seat 3 is driven by a servo motor; a fixed arm 4 is rotatably connected to the end face of the rotating seat 3, and a pulley group is installed inside the support arm; a fixing component is installed between the fixed arm 4 and the workbench 1; the fixing component is used to lock the fixed arm 4 to prevent it from rotating with the rotating seat 3; one end of the fixed arm 4 away from the fixing component is slidably connected to a pressing plate 5 through an elastic component; a pair of symmetrically arranged sockets 6 are formed on the surface of the rotating seat 3; a winding arm 601 is jointly inserted into the two sockets 6; the winding arm 601 is U-shaped, including two horizontal arms and a vertical arm; conduits 7 and counterweight pipes 8 are fixedly connected to the two ends of the winding arm 601 respectively; a robotic arm 9 is installed on one side of the top surface of the workbench 1 away from the fixing component; the robotic arm 9 is used to pull and cut the wire at the conduit 7; a feeding component is installed on one side of the top surface of the workbench 1 close to the robotic arm 9; the feeding component is used to transfer the stator; during operation, in order to reduce the difficulty for the user to replace the copper wire of the winding machine, the embodiment of the present invention can be used. First, the user pulls out the fixed arm 4 on the surface of the rotating seat 3 from the socket 6 on the surface of the rotating seat 3 and takes it outside the embodiment of the present invention. Then, the user can pass the copper wire to be used through the pulley group and then pass it out from the conduit 7. Subsequently, the user can insert the fixed arm 4 with the wire passed through back into the socket 6 on the surface of the rotating seat 3. Then, the wire at the conduit 7 is fixed to the robotic arm 9. Subsequently, the feeding component presses the teeth of the stator against the pressing plate 5 at the end of the fixed arm 4. Then, the rotating seat 3 rotates, driving the winding arm 601 to rotate, so that the copper wire is wound around the teeth on the surface of the stator. During the process of the rotating seat 3 driving the winding arm 601 to rotate, the setting of the counterweight pipe 8 and the winding pipe makes the weights at both ends of the winding arm 601 balanced, thus reducing the vibration of the winding arm 601. After the copper wire is wound around each tooth on the surface of the stator, the robotic arm 9 cuts the copper wire, and the winding operation of the stator can be completed. Through the plug-and-play setting between the winding arm 601 and the socket 6, the user can take the winding arm 601 to be threaded with copper wire outside the embodiment of the present invention, so that the user has a larger operating space, which is convenient for the user to perform the threading operation. At the same time, the user can also prepare multiple winding arms 601 and thread the copper wire in advance. Thus, when the copper wire is used up, the pre-threaded winding arm 601 is directly replaced with the winding arm 601 on the rotating seat 3, thereby improving the replacement efficiency.

[0023] As Figures 2 to 3As shown, the fixing component includes an upper magnet column 10 and a lower magnet column 11; the attraction between the magnet column 10 and the lower magnet column 11 is greater than the frictional force between the rotating seat 3 and the fixed arm 4; the upper magnet column 10 is fixedly connected to the end of the fixed arm 4 away from the robotic arm 9; the lower magnet column 11 is fixedly connected to the top surface of the workbench 1 and is located at the bottom of the lower magnet column 11; a reflective sticker 12 is fixedly connected to the surface of the wire winding arm 601 at a position corresponding to the lower magnet column 11; a photoelectric tachometer 13 is embedded in the top surface of the lower magnet column 11; during operation, when the rotating seat 3 rotates, since the upper magnet column 10 at the end of the fixed arm 4 attracts the lower magnet column 11 on the top surface of the workbench 1, the fixed arm 4 will not rotate together with the rotating seat 3, thus ensuring that the pressing plate 5 at the end of the fixed arm 4 can normally press against the teeth of the stator. At the same time, when the wire winding arm 601 rotates, the reflective sticker on its surface will continuously pass through the photoelectric tachometer 13 on the top surface of the lower magnet column 11, so that the photoelectric tachometer 13 can measure the number of rotation cycles and the rotational speed of the wire winding arm 601, facilitating the user to adjust the rotational speed of the rotating seat 3, and thus making the copper wire wound on the surface of the stator more evenly.

[0024] As Figures 4 to 5 shown, one end of the conduit 7 away from the wire winding arm 601 is rotatably connected to a pair of clamping arms 14; an elastic band 15 is rotatably connected between the two clamping arms 14; one end of the two clamping arms 14 away from the conduit 7 is rotatably connected to a pressing roller 16; a pair of dial plates 17 are fixedly connected to the end of each clamping arm 14 away from the pressing roller 16; during operation, when the user passes the copper wire through the wire winding arm 601, the user needs to pinch the two pairs of dial plates 17, causing the dial plates 17 to drive the two clamping arms 14 to rotate away from each other, so that the pressing rollers 16 at the ends of the clamping arms 14 no longer press together, and stretching the elastic band 15 to enable the copper wire to pass through the conduit 7 smoothly. When the copper wire passes through the conduit 7, the user releases the pinched dial plates 17, and the stretched elastic band 15 returns, driving the two pressing rollers 16 to clamp the copper wire, thereby fixing the position of the copper wire, facilitating the user to store the wire winding arm 601 with the copper wire passed through it, preventing the copper wire from falling into the interior of the conduit 7 due to lack of fixation during storage, and also being able to fix the wire group composed of multiple copper wires to prevent the copper wires at its end from spreading.

[0025] As Figure 5As shown, a connecting rod 18 is rotatably connected between the paired dial plates 17; two pairs of symmetrically arranged limiting blocks 19 are fixedly connected to the inner wall of the socket 6; one end of one pair of the limiting blocks 19 away from the robotic arm 9 is fixedly connected to a top plate 20; a slot 21 is formed at a position corresponding to the top plate 20 on the surface of the wire winding arm 601 close to the conduit 7; a pressing plate 22 is arranged in the slot 21; a pulling rope 23 is installed between the pressing plate 22 and the connecting rod 18, and the pulling rope 23 penetrates through the wire winding arm 601; a first spring 24 is fixedly connected between the pressing plate 22 and the inner wall of the slot 21; during operation, when the user inserts the wire winding arm 601 into the socket 6, the user needs to orient the end of the wire winding arm 601 provided with the slot 21 towards the socket 6 containing the top plate 20 inside. At this time, the user inserts the wire winding arm 601 into the socket 6, and the top plate 20 on the surface of the limiting block 19 will be inserted into the slot 21 on the surface of the wire winding arm 601, thereby squeezing the pressing plate 22 in the slot 21 and stretching the first spring 24, so that the pressing plate 22 pulls the connecting rod 18 through the pulling rope 23, and then the connecting rod 18 drives the dial plate 17 and the clamping arm 14 to rotate, so that the two clamping arms 14 move away from each other, thus avoiding the copper wire being clamped by the pressing roller 16 when the wire winding arm 601 is performing wire winding work, resulting in poor wire winding of the copper wire. At the same time, since both the pressing roller and the elastic band are rotatably connected, during the winding process of the copper wire, the copper wire will only contact the pressing roller and the elastic band, thereby avoiding contact with the edge of the guiding tube, and reducing the probability of the outer insulating paint peeling off due to friction during the winding of the copper wire through the rotation of the pressing roller and the elastic band.

[0026] As Figure 4 , Figure 6 and Figure 7 shown, a limiting hole 25 is formed at the bottom of the slot 21; a limiting rod 26 is fixedly connected to one side of the pressing plate 22 close to the limiting hole 25; the limiting rod 26 is slidably connected to the limiting hole 25; a sliding rod 27 is fixedly connected between the pulling rope 23 and the pressing plate 22; during operation, when the top plate 20 squeezes the pressing plate 22, the limiting rod 26 will cooperate with the limiting hole 25 to limit the movement of the pressing plate 22 and prevent it from tilting. At the same time, the sliding rod 27 can also limit the pressing plate 22, thereby avoiding the pressing plate 22 from deflecting in the slot 21 and causing the pulling rope 23 to be unable to correctly pull the dial plate 17.

[0027] As Figure 7As shown, grooves 28 are formed on the sides of the two horizontal arms of the winding arm 601 that are close to each other; a pressing block 29 is slidably connected in the groove 28, and the pressing block 29 is wedge-shaped; a second spring 30 is fixedly connected between the pressing block 29 and the groove 28; during operation, when the user inserts the winding arm 601 into the socket 6, the pressing block 29 at the groove 28 will be blocked by the inner wall of the socket 6, so that the pressing block 29 is pressed into the socket 6 and compresses the second spring 30. When the limiting block 19 abuts against the winding arm 601, the pressing block 29 is just outside the rotating seat 3 at this time. Then the compressed second spring 30 rebounds and pushes the pressing block 29 out of the groove 28. At this time, one side of the pressing block 29 will fit against the surface of the rotating seat 3, so as to cooperate with the limiting block 19 and the pressing block 29 to clamp the winding arm 601, realizing the locking of the winding arm 601 and preventing the winding arm 601 from disengaging from the socket 6 when the rotating seat 3 drives the winding arm 601 to rotate.

[0028] As Figure 8 shown, a through groove 31 is formed on the side surface of the fixed arm 4; two pressing rods 32 are slidably connected to both ends of the through groove 31; a double-threaded screw rod 33 is rotatably connected in the through groove 31, and the two pressing rods 32 are respectively threadedly connected to both ends of the double-threaded screw rod 33; an adjusting rod 34 is rotatably connected to the surface of the fixed arm 4; the adjusting rod 34 and the double-threaded screw rod 33 are connected by a gear set 40; during operation, when the user needs to release the locking of the winding arm 601, the user needs to rotate the rotating seat 3 to align the pressing block 29 on the surface of the pressing rod 32 with the pressing rod 32. Then the user rotates the adjusting rod 34, which drives the double-threaded screw rod 33 to rotate, and then the double-threaded screw rod 33 drives the pressing rod 32 in the through groove 31 to slide out along the through groove 31, so that the pressing rod 32 can squeeze the pressing block 29 at the groove 28 of the winding arm 601, making the pressing block 29 be pressed into the groove 28 and compressing the second spring 30. At this time, the user can pull out the winding arm 601 from the socket 6. Driven by the adjusting rod 34, the pressing rod 32 synchronously squeezes the pressing block 29, which can more quickly release the locking of the winding arm 601 and facilitate the disassembly of the winding arm 601.

[0029] As Figure 1 and Figure 9As shown, the feeding component includes a moving seat 35; the moving seat 35 is slidably connected to the top surface of the workbench 1 and is driven by a servo motor; a connecting seat 36 is rotatably connected to the top surface of the moving seat 35; a fixing rod 37 is installed on the top surface of the connecting seat 36; the fixing rod 37 is of a hollow structure and is communicated with an external air pump through an air pipe; a plurality of uniformly arranged pressing rods 38 are slidably connected to the surface of the fixing rod 37; during operation, when it is necessary to transport the stator to be wound to the winding arm 601, the user needs to first pump air out through the air pump to retract the pressing rods 38 on the surface of the fixing rod 37 towards the fixing rod 37, and then the user can put the stator on the fixing rod 37. Subsequently, the air pump pumps air into the fixing rod 37, so that the pressing rods 38 press against the inner wall of the stator, and the stator is fixed by the friction force between the pressing rods 38 and the inner wall of the stator. Then the moving seat 35 drives the stator to move to the winding arm 601 for winding operation. Through the cooperation of the fixing rod 37 and the pressing rods 38, the fixing rod 37 and the pressing rods 38 can adapt to various stators with different inner diameters, thereby expanding the application range of the embodiment of the present invention.

[0030] As Figure 1 and Figure 9 As shown, a pair of symmetrically arranged rotating rods 39 are fixedly connected to the bottom of the fixing rod 37; the rotating rods 39 are rotatably connected to the connecting seat 36; gears 40 are fixedly connected to the ends of the rotating rods 39 away from the fixing rod 37; a pair of toothed plates 41 are fixedly connected to the top surface of the workbench 1 and on the side away from the support plate 2, and the toothed plates 41 can be engaged with the gears 40; a conveyor belt 42 is installed on the top surface of the table, and the conveyor belt 42 is located on the side of the toothed plates 41 away from the support plate 2; during operation, when the stator winding is completed, the moving seat 35 drives the fixing rod 37 and the stator to move towards the toothed plates 41. During this process, the gears 40 at the ends of the rotating rods 39 will be engaged with the toothed plates 41, and then the rotating rods 39 and the fixing rod 37 are driven by the gears 40 to rotate, so that the fixing rod 37 rotates from the vertical state to the horizontal state. At this time, the stator is just at the conveyor belt 42. Subsequently, the gas in the fixing rod 37 is evacuated, and the pressing rods 38 no longer press against the inner wall of the stator. Then the moving seat 35 drives the fixing rod 37 to withdraw from the stator, so that the stator can be sent away by the conveyor belt 42 and the blanking operation is completed, thereby improving the blanking efficiency.

[0031] As Figure 9As shown in the figure, one end of the moving seat 35 close to the support plate 2 is rotatably connected with a baffle plate 43, and a torsion spring is installed at the rotation connection of the baffle plate 43 and the moving seat 35; a magnet block 44 is fixedly connected to the top of the baffle plate 43; a metal ring 45 is fixedly connected to the surface of the fixed rod 37 at a position corresponding to the magnet block 44, and the metal ring 45 is made of magnetizable metal; during operation, when the fixed rod 37 is in a vertical state, the metal ring 45 on the surface of the fixed rod 37 will be attached to the magnet block 44 on the surface of the baffle plate 43, so that the fixed rod 37 and the baffle plate 43 are adsorbed together, thereby realizing the limit of the fixed rod 37, and further avoiding that when the pressing plate 5 presses the stator, the stator and the fixed rod 37 are pushed together, resulting in incorrect copper wire winding.

[0032] During operation, in order to reduce the difficulty for the user to replace the copper wire of the winding machine, the embodiments of the present invention can be used. First, the user pulls out the fixed arm 4 on the surface of the rotating seat 3 from the socket 6 on the surface of the rotating seat 3 and takes it outside the embodiments of the present invention. Then, the user can pass the copper wire to be used through the pulley group and then pass it out from the conduit 7. Subsequently, the user can insert the fixed arm 4 with the wire passed through back into the socket 6 on the surface of the rotating seat 3, and then fix the wire at the conduit 7 to the robotic arm 9. Then, the feeding assembly presses the teeth of the stator against the pressing plate 5 at the end of the fixed arm 4. After that, the rotating seat 3 rotates, driving the winding arm 601 to rotate, so that the copper wire is wound around the teeth on the surface of the stator. During the process of the rotating seat 3 driving the winding arm 601 to rotate, the setting of the counterweight pipe 8 and the winding pipe makes the weights at both ends of the winding arm 601 balanced, thereby reducing the vibration of the winding arm 601. After the teeth on the surface of the stator are all wound with copper wire, the robotic arm 9 cuts off the copper wire, and the winding operation of the stator can be completed. Through the plug-and-play setting between the winding arm 601 and the socket 6, the user can take the winding arm 601 to be threaded with copper wire outside the embodiments of the present invention, so that the user has a larger operating space, which is convenient for the user to perform the threading operation. At the same time, the user can also prepare multiple winding arms 601 and thread the copper wire in advance, so that when the copper wire is used up, the pre-threaded winding arm 601 can be directly replaced with the winding arm 601 on the rotating seat 3, thereby improving the replacement efficiency.

[0033] When the rotating seat 3 rotates, since the upper magnet column 10 at the end of the fixed arm 4 and the lower magnet column 11 on the top surface of the workbench 1 attract each other, the fixed arm 4 will not rotate with the rotating seat 3, ensuring that the pressing plate 5 at the end of the fixed arm 4 can normally press against the teeth of the stator. At the same time, when the winding arm 601 rotates, the reflective stickers on its surface will continuously pass through the photoelectric speed detector 13 on the top surface of the lower magnet column 11, so that the photoelectric speed detector 13 can measure the number of rotation cycles and the rotation speed of the winding arm 601, facilitating the user to adjust the rotation speed of the rotating seat 3, and making the copper wire wound on the surface of the stator more evenly.

[0034] After the user passes the copper wire through the winding arm 601, the user needs to pinch two pairs of shifting plates 17, so that the shifting plates 17 drive the two clamping arms 14 to rotate in a direction away from each other, so that the pressing rollers 16 at the ends of the clamping arms 14 no longer press together, and stretch the elastic band 15, so that the copper wire can pass through the conduit 7 smoothly. After the copper wire passes through the conduit 7, the user releases the pinched shifting plates 17, and the stretched elastic band 15 returns, thereby driving the two pressing rollers 16 to clamp the copper wire, and then fixing the position of the copper wire, which is convenient for the user to store the winding arm 601 with the copper wire passed through, and avoids the copper wire falling into the interior of the conduit 7 during storage due to lack of fixation.

[0035] When the user inserts the winding arm 601 into the socket 6, the user needs to orient the end of the winding arm 601 provided with the slot 21 towards the socket 6 containing the top plate 20 inside. At this time, the user inserts the winding arm 601 into the socket 6, and the top plate 20 on the surface of the limit block 19 will insert into the slot 21 on the surface of the winding arm 601, and then squeeze the pressure plate 22 in the slot 21 and stretch the first spring 24, so that the pressure plate 22 pulls the connecting rod 18 through the pull rope 23, and then the connecting rod 18 drives the shifting plate 17 and the clamping arm 14 to rotate, so that the two clamping arms 14 move in a direction away from each other, thereby avoiding the copper wire being clamped by the pressing rollers 16 during the winding operation of the winding arm 601, resulting in poor copper wire winding.

[0036] When the top plate 20 squeezes the pressure plate 22, the limit rod 26 will cooperate with the limit hole 25 to limit the movement of the pressure plate 22 and prevent it from tilting. At the same time, the sliding rod 27 can also limit the pressure plate 22, thereby avoiding the pressure plate 22 deflecting in the slot 21, resulting in the pull rope 23 being unable to correctly pull the shifting plate 17.

[0037] When the user inserts the winding arm 601 into the socket 6, the abutting block 29 at the groove 28 will be blocked by the inner wall of the socket 6, so that the abutting block 29 is pressed into the socket 6 and compresses the second spring 30. When the limit block 19 abuts against the winding arm 601, at this time the abutting block 29 is just outside the rotating seat 3. At this time, the compressed second spring 30 rebounds and pushes the abutting block 29 out of the groove 28. At this time, one side of the abutting block 29 will fit with the surface of the rotating seat 3, so as to cooperate with the limit block 19 and the abutting block 29 to clamp the winding arm 601, realizing the locking of the winding arm 601 and avoiding the winding arm 601 coming out of the socket 6 when the rotating seat 3 drives the winding arm 601 to rotate.

[0038] When the user needs to unlock the winding arm 601, the user needs to rotate the rotating seat 3 so that the abutting block 29 on the surface of the abutting rod 32 aligns with the abutting rod 32. Then the user rotates the adjusting rod 34, which drives the double-threaded screw rod 33 to rotate. The double-threaded screw rod 33 then drives the abutting rod 32 in the through groove 31 to slide outward along the through groove 31, so that the abutting rod 32 can squeeze the abutting block 29 at the groove 28 of the winding arm 601, causing the abutting block 29 to be pressed into the groove 28 and compressing the second spring 30. At this time, the user can pull out the winding arm 601 from the socket 6. Driven by the adjusting rod 34, the abutting rod 32 synchronously squeezes the abutting block 29, which can more quickly unlock the winding arm 601, facilitating the disassembly of the winding arm 601.

[0039] When the stator to be wound needs to be transported to the winding arm 601, the user needs to first pump air out through the air pump to retract the pressing rod 38 on the surface of the fixing rod 37 towards the fixing rod 37. Then the user can put the stator on the fixing rod 37. Subsequently, the air pump pumps air into the fixing rod 37, so that the pressing rod 38 abuts against the inner wall of the stator, and the stator is fixed by the frictional force between the pressing rod 38 and the inner wall of the stator. Then the moving seat 35 drives the stator to move to the winding arm 601 for winding operation. Through the cooperation of the fixing rod 37 and the pressing rod 38, the fixing rod 37 and the pressing rod 38 can adapt to various stators with different inner diameters, thus expanding the scope of application of the embodiment of the present invention.

[0040] After the stator winding is completed, the moving seat 35 drives the fixing rod 37 and the stator to move towards the toothed plate 41. During this process, the gear 40 at the end of the rotating rod 39 meshes with the toothed plate 41, and then the gear 40 drives the rotating rod 39 and the fixing rod 37 to rotate, so that the fixing rod 37 rotates from the vertical state to the horizontal state. At this time, the stator is just at the conveyor belt 42. Subsequently, the gas in the fixing rod 37 is evacuated, and the pressing rod 38 no longer presses against the inner wall of the stator. Then the moving seat 35 drives the fixing rod 37 to withdraw from the stator, so that the stator can be sent away by the conveyor belt 42 and the blanking operation is completed, thereby improving the blanking efficiency.

[0041] When the fixing rod 37 is in the vertical state, the metal ring 45 on the surface of the fixing rod 37 will abut against the magnet block 44 on the surface of the baffle 43, so that the fixing rod 37 and the baffle 43 are adsorbed together, thereby realizing the limitation of the fixing rod 37, and avoiding the stator and the fixing rod 37 being pushed together when the pressing plate 5 presses the stator, which may cause the copper wire to be wound incorrectly.
