Description

Technical Field

[0001] The present invention relates to the technical field of winding and inserting machines, and more specifically, to an automatic winding and inserting machine for generator stator coils. Background Art

[0002] An automotive generator is the main power source of an automobile. Its function is to supply power to all electrical devices (except the starter) when the engine is running normally, and at the same time charge the battery. The generator stator coil refers to the stationary coil, usually composed of multiple parallel coils, and its main function is to generate electrical energy through the principle of electromagnetic induction. When the rotor of the generator rotates, the magnetic lines of force in the stator coil will change, thereby generating an induced electromotive force in the stator coil, and then outputting electrical energy through the terminal.

[0003] When processing the motor stator, it is necessary to wind the enameled wire around the stator core. Since multiple turns of coils need to be wound around the stator core, in order to improve the winding efficiency, the wire is generally wound in advance by manual or mechanical winding, and then the wound coil is sleeved on two guide bars, and then the guide bars are passed through the inner slots of the stator core and respectively arranged at both ends of the stator core. Subsequently, the wound coil on the guide bar is pushed into the stator core to achieve the embedding of multiple groups of coils. However, the problem is that the generator stator core is generally of a "T" - shaped structure. When pushing the coil, in order not to be stuck by the top end of the stator core, the single - turn circumference of the coil needs to be greater than the circumference of the top end of the stator core. However, the circumference of the bottom end of the stator core is smaller than that of the top end, which will cause a large gap between the coil pushed into the bottom end of the stator core and the wall surface of the bottom end of the stator core, resulting in the looseness of the stator coil. This will not only affect the inductance of the motor, but also cause an increase in current, thus causing the motor to heat severely and even possibly burn out the motor. Summary of the Invention

[0004] In view of this, the purpose of the present invention is to solve the problem that when winding and inserting the stator coil, there is a large gap between the coil pushed into the bottom end of the stator core and the wall surface of the bottom end of the stator core, resulting in the looseness of the stator coil, which will not only affect the inductance of the motor, but also cause an increase in current, thus causing the motor to heat severely and even possibly burn out the motor.

[0005] The purpose of the present invention is to provide an automatic winding and inserting machine for generator stator coils. After fixing the stator, it winds and pulls the wire repeatedly onto the stator core through a reciprocating structure, so that the formed coil fits the wall surface of the stator core, thereby avoiding the looseness of the stator coil.

[0006] To achieve the above - mentioned purpose, the present invention provides an automatic winding and inserting machine for generator stator coils, including a winding table and a winding body arranged on the winding table. The winding table is used to fix the generator stator core;

[0007] The wire winding body includes a cantilever, a reciprocating member, and a wire pulling member for wire release. The reciprocating member is located at one end of the cantilever. The reciprocating member is in driving connection with the cantilever and is used to drive the wire pulling member to move. The other end of the cantilever is slidably connected to the winding table for adjusting the height of the wire pulling member;

[0008] After fixing the generator stator core on the winding table, slide the cantilever to drive the wire pulling member close to the bottom wall surface of the generator stator core. Then, drive the reciprocating member by the cantilever to make a reciprocating motion. Further, drive the wire pulling member by the reciprocating member to move around the generator stator core for wire release;

[0009] In the above process, when the reciprocating member makes a reciprocating motion, it synchronously drives the wire pulling member to move upward to adjust the wire release height of the wire pulling member, so that the wire released by the wire pulling member can fit on the wall surface of the generator stator core, thereby avoiding the looseness of the stator core coil.

[0010] As a further improvement of this technical solution, the winding table includes a horizontally placed plate and a vertically placed plate provided at one end of the horizontally placed plate. A placing groove is provided at the top of the horizontally placed plate. The cantilever is slidably connected to the vertically placed plate. The winding table further includes an end frame provided on the horizontally placed plate. A first screw shaft is rotatably connected inside the end frame. The first screw shaft is in threaded connection with the end of the cantilever. By rotating the first screw shaft, the first screw shaft drives the cantilever to move up and down along the vertically placed plate until the wire pulling member is close to the bottom wall surface of the generator stator core;

[0011] Specifically, place the generator stator in the groove and adjust the placement angle so that the generator stator core faces the wire pulling member. Rotate the first screw shaft to drive the cantilever to move up and down along the vertically placed plate until the wire pulling member is close to the bottom wall surface of the generator stator core.

[0012] As a further improvement of this technical solution, a motor and a driving rod in driving connection with the motor are provided inside the cantilever. The reciprocating member is located at the end of the cantilever away from the vertically placed plate. The driving rod is in reciprocating threaded connection with the reciprocating member. The cantilever drives the driving rod to rotate through the built-in motor. Further, the rotation of the driving rod drives the reciprocating member to make a reciprocating motion, thereby driving the wire pulling member to move around the generator stator core for wire release.

[0013] As a further improvement of this technical solution, a reciprocating groove is opened at the end of the cantilever away from the vertically placed plate. The reciprocating member includes a reciprocating plate and a hanging plate located at the bottom of the reciprocating groove. The reciprocating plate is slidably connected to the reciprocating groove. The driving rod is in reciprocating threaded connection with the reciprocating plate. A displacement structure in sliding connection is provided at the bottom end of the reciprocating plate. The displacement structure is in sliding connection with the hanging plate. The displacement structure is connected to the wire pulling member;

[0014] When the driving rod rotates, it drives the reciprocating plate to make a reciprocating slide along the reciprocating groove. The reciprocating plate further drives the wire pulling member to move around the generator stator core for wire release through the displacement structure.

[0015] As a further improvement of the technical solution, a first chute is provided at the bottom end of the reciprocating plate. The displacement structure includes a slider and a connecting plate slidably connected to the bottom surface of the hanging plate. The slider is slidably connected to the inner wall of the first chute. The bottom end of the slider is rotatably connected to one end of the connecting plate. The other end of the connecting plate is connected to a wire pulling member. The hanging plate is an "O"-shaped structural plate;

[0016] During the process of the driving rod driving the reciprocating plate to slide back and forth, the reciprocating plate drives the connecting plate through the slider, and then drives the wire pulling member to move along the hanging plate through the connecting plate. Since the hanging plate is an "O"-shaped structure, the displacement trajectory of the wire pulling member is an "O"-shaped trajectory around the generator stator core, so that the wire released by the wire pulling member is conveniently wound around the surface of the generator stator core to form a coil.

[0017] As a further improvement of the technical solution, the wire pulling member includes a wire pulling plate, a wire winding drum and a wire releasing head. One side of the middle part of the wire pulling plate is connected to the connecting plate. Card slots are provided at both the front and rear ends of the wire pulling plate. A wire winding drum for releasing copper wire is installed in the card slot. A wire releasing head for guiding the release of copper wire is provided at the bottom of the middle part of the wire pulling plate;

[0018] Furthermore, a connecting cylinder is provided at the bottom end of the middle part of the wire pulling plate. The top end of the wire releasing head is rotatably connected to the connecting cylinder;

[0019] Before winding the wire, one end of the copper wire on the wire winding drum is passed through the wire releasing head and fixed on the generator stator core. When the wire pulling plate drives the "O"-shaped trajectory around the generator stator core to move, the copper wire on the wire winding drum is continuously unwound, and under the pulling of the fixed end of the copper wire on the generator stator core, the unwound copper wire can be straightened and thus attached to the bottom wall surface of the generator stator core.

[0020] Among them, the wire releasing head is set to be rotatably connected so that when the wire pulling plate is driven through the turning point, the wire releasing head can rotate adaptively to reduce the bending angle of the copper wire, thereby avoiding the breakage of the copper wire released by the wire releasing head due to too large an angle.

[0021] Considering that when the height of the wire releasing head remains unchanged, except for the copper wire released in the first circle of the wire pulling plate that can be attached to the wall surface of the generator stator core, the copper wire released during the subsequent circular motion of the wire pulling plate will be superimposed on the copper wire released in the first circle, resulting in a relatively large distance between the formed coil and the wall surface of the generator stator core, thus causing the phenomenon of looseness of the coil.

[0022] As a further improvement of the technical solution, the reciprocating member further includes a second screw shaft. One end of the top of the second screw shaft passes through the connecting plate and the rotating connection part of the slider. The second screw shaft is threadedly connected to the rotating connection part. A second chute is provided in the slider. One end of the top of the second screw shaft is slidably connected to the inner wall of the second chute up and down. One end of the bottom of the second screw shaft is connected to the wire releasing head;

[0023] When the connecting plate drives the wire pulling plate through the turning point, since the top end of the second screw shaft can only slide up and down along the second chute, the rotating connecting part will drive the second screw shaft to move up when rotating, and then drive the wire releasing head to move up, so that the copper wire released in each circular motion process is not at the same height, thus ensuring that the copper wires will not be stacked and can fit on the wall surface of the generator stator core, and preventing the occurrence of coil loosening on the wall surface.

[0024] As a further improvement of this technical solution, a top rod is provided at the top of the wire releasing head. One end of the top of the top rod is inserted and matched with the bottom of the connecting cylinder. A connecting arm is sleeved on the surface of the top rod. The top rod is connected to one end of the bottom of the second screw shaft through the provided connecting arm. By setting the insertion and matching of the top rod and the connecting cylinder and the connection of the connecting arm and the insertion rod, it can be ensured that the wire releasing head can not only rotate but also be driven by the second screw shaft to move up synchronously;

[0025] Furthermore, the second screw shaft is inserted and matched with an insertion rod. A slot is correspondingly opened on the surface of the connecting arm. One end of the insertion rod is inserted and matched with the slot. By setting the insertion and matching method, the insertion rod can be pulled out and removed from the second screw shaft to release the connection between the wire releasing head and the second screw shaft, thus facilitating the disassembly of the wire releasing head for operations such as threading.

[0026] In the present invention, the cantilever drives the reciprocating member to perform reciprocating motion along one end of the cantilever, and then the reciprocating member drives the wire pulling member to move and release wire around the generator stator core. Moreover, when the cantilever drives the reciprocating member to perform reciprocating motion, the reciprocating member synchronously drives the wire pulling member to move up, so as to adjust the wire releasing height of the wire pulling member to ensure that the wire released by the wire pulling member can fit on the wall surface of the generator stator core and avoid the loosening of the stator core coil.

[0027] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0028] 1. In this automatic winding and embedding machine for generator stator coils, when the driving rod drives the reciprocating plate to reciprocate along the reciprocating groove, the reciprocating plate drives the wire pulling member to move along the hanging plate, and the wire released by the wire pulling member forms a coil around the surface of the generator stator core. In addition, when the connecting plate drives the wire pulling plate through the turning point, the rotating connecting part between the connecting plate and the slider will rotate, and then drive the wire releasing head to move up through the second screw shaft, so that the copper wires released in each circular motion process are not at the same height, thus ensuring that the copper wires will not be stacked and can fit on the wall surface of the generator stator core, avoiding the occurrence of coil loosening, and ensuring the winding and embedding processing quality of the generator stator coils.

[0029] 2. In the automatic winding and embedding machine for the stator coil of the generator, the copper wire on the take-up reel is continuously unwound, and under the pulling of one end of the copper wire fixed on the stator core of the generator, the unwound copper wire can be straightened and thus fit on the bottom wall surface of the stator core of the generator. And when the wire pulling plate is driven by the connecting plate to pass through the turning point, the wire feeding head can rotate adaptively to reduce the bending angle of the copper wire, thereby avoiding the breakage of the copper wire released by the wire feeding head due to excessive angle.

Thus, the features defined with "first" and "second" may explicitly or implicitly include one or more of such features. In the description of the present invention, "a plurality of" means two or more, unless otherwise specifically defined.

[0046] Please refer to Figure 1 、 Figure 3 As shown in the figure, the purpose of this embodiment is to provide an automatic winding and embedding machine for generator stator coils, including a winding table 1 and a coiling body 2 arranged on the winding table 1. The winding table 1 is used to fix the generator stator core;

[0047] The winding body 2 includes a cantilever 21, a reciprocating member 22, and a wire-drawing member 23 for wire pay-out. The reciprocating member 22 is located at one end of the cantilever 21. The reciprocating member 22 is in transmission connection with the cantilever 21 and is used to drive the wire-drawing member 23 to move. The other end of the cantilever 21 is slidably connected to the winding table 1 for adjusting the height of the wire-drawing member 23. After placing the generator stator core on the winding table 1 and fixing it, slide the cantilever 21 to make the wire-drawing member 23 close to the bottom wall surface of the generator stator core. The cantilever 21 drives the reciprocating member 22 to make a reciprocating motion along one end of the cantilever 21, and then the reciprocating member 22 drives the wire-drawing member 23 to move around the generator stator core for wire pay-out. Moreover, when the cantilever 21 drives the reciprocating member 22 to make a reciprocating motion, the reciprocating member 22 synchronously drives the wire-drawing member 23 to move upward, so as to adjust the wire pay-out height of the wire-drawing member 23, ensuring that the wire paid out by the wire-drawing member 23 can adhere to the wall surface of the generator stator core and avoiding the looseness of the stator core coil.

[0048] The above structure is disclosed as follows:

[0049] In order to place the generator stator core and adjust the height of the wire-drawing member 23 so that the wire-drawing member 23 is close to the bottom wall surface of the generator stator core, as Figure 2 , Figure 3 , Figure 4 shown, the winding table 1 includes a horizontally arranged plate 11 and a vertically arranged plate 12 provided at one end of the horizontally arranged plate 11. A placing groove 111 for placing the generator stator core is provided at the end of the horizontally arranged plate 11 away from the vertically arranged plate 12. A groove for accommodating the generator stator core is opened on the upper surface of the placing groove 111. One end of the cantilever 21 close to the vertically arranged plate 12 is located inside the vertically arranged plate 12 and is slidably connected to the vertically arranged plate 12 up and down. The winding table 1 further includes an end frame 13 provided at one end of the horizontally arranged plate 11 close to the vertically arranged plate 12. The end of the cantilever 21 is located inside the end frame 13. A first screw shaft 131 is rotatably connected inside the end frame 13. The bottom end of the first screw shaft 131 passes through the end of the cantilever 21 and is threadedly connected to the end of the cantilever 21. After passing the reciprocating member 22 and the wire-drawing member 23 through the generator stator, place the generator stator in the groove of the placing groove 111 and adjust the placing angle of the generator stator so that the generator stator core faces the wire-drawing member 23. Then rotate the first screw shaft 131 to drive the cantilever 21 to move up and down along the vertically arranged plate 12 until the wire-drawing member 23 is close to the bottom wall surface of the generator stator core.

[0050] After adjusting the height of the cantilever 21 so that the wire-drawing member 23 is close to the bottom wall surface of the generator stator, as Figure 4 , Figure 5As shown, a motor and a driving rod 211 drivingly connected to the motor are provided inside the cantilever 21. The reciprocating member 22 is located at one end of the cantilever 21 away from the vertical plate 12. The driving rod 211 passes through the reciprocating member 22 and is in reciprocating threaded connection with the reciprocating member 22. After the wire pulling member 23 is close to the bottom wall surface of the generator stator, the cantilever 21 drives the driving rod 211 to rotate through the built-in motor, and then drives the reciprocating member 22 to reciprocate through the rotation of the driving rod 211, thereby driving the wire pulling member 23 to move and pay out the wire around the generator stator core.

[0051] Specifically, as Figure 5 shown, a reciprocating groove 212 is formed at one end of the cantilever 21 away from the vertical plate 12. The driving rod 211 is located inside the reciprocating groove 212. The reciprocating member 22 includes a reciprocating plate 221 and a hanging plate 222 located at the bottom of the reciprocating groove 212. The reciprocating plate 221 is located inside the reciprocating groove 212 and is slidably connected to the reciprocating groove 212. One end of the driving rod 211 passes through the reciprocating plate 221 and is in reciprocating threaded connection with the reciprocating plate 221. A displacement structure is slidably connected to the bottom end of the reciprocating plate 221. The displacement structure is slidably connected to the hanging plate 222. The displacement structure is connected to the wire pulling member 23. When the driving rod 211 rotates, it drives the reciprocating plate 221 to reciprocate along the reciprocating groove 212, and the reciprocating plate 221 then drives the wire pulling member 23 to move and pay out the wire around the generator stator core through the displacement structure.

[0052] The following specifically discloses the displacement structure:

[0053] As Figure 6 shown, a first sliding groove 2211 is formed at the bottom end of the reciprocating plate 221. The displacement structure includes a slider 2212 and a connecting plate 223 slidably connected to the bottom surface of the hanging plate 222. The top end of the slider 2212 is located inside the first sliding groove 2211 and is slidably connected to the inner wall of the first sliding groove 2211. The bottom end of the slider 2212 is rotatably connected to one end of the connecting plate 223. The other end of the connecting plate 223 is connected to the wire pulling member 23. The hanging plate 222 is an "O"-shaped structural plate. During the process of the driving rod 211 driving the reciprocating plate 221 to reciprocate along the reciprocating groove 212, the reciprocating plate 221 drives the connecting plate 223 through the slider 2212, and then drives the wire pulling member 23 to move along the hanging plate 222 through the connecting plate 223. Since the hanging plate 222 is an "O"-shaped structure, the displacement trajectory of the wire pulling member 23 is an "O"-shaped trajectory around the generator stator core, so that the wire paid out by the wire pulling member 23 can be wound around the surface of the generator stator core to form a coil.

[0054] When the wire pulling member 23 moves around the generator stator core, in order to ensure that the wire can be paid out and wound around the core surface, as Figure 8 、 Figure 9As shown, the wire pulling member 23 includes a wire pulling plate 231, a wire winding drum 232, and a wire releasing head 234. One side of the middle part of the wire pulling plate 231 is connected to one end of the connecting plate 223 away from the slider 2212. Card slots are formed at both the front and rear ends of the wire pulling plate 231, and the wire winding drum 232 for releasing the copper wire is installed in the card slots. A wire releasing head 234 for guiding the release of the copper wire is arranged at the bottom of the middle part of the wire pulling plate 231, and a connecting cylinder 233 is arranged at the bottom end of the middle part of the wire pulling plate 231. The top end of the wire releasing head 234 is rotatably connected to the connecting cylinder 233. Before starting to wind the wire, one end of the copper wire on the wire winding drum 232 is passed through the wire releasing head 234 and then fixed on the generator stator core. When the wire pulling plate 231 is driven by the connecting plate 223 to move along an "O"-shaped trajectory around the generator stator core, the copper wire on the wire winding drum 232 is continuously unwound, and under the pulling of the fixed end of the copper wire on the generator stator core, the unwound copper wire can be straightened and thus attached to the bottom wall surface of the generator stator core. Among them, the reason for arranging the wire releasing head 234 to be rotatably connected is that when the wire pulling plate 231 is driven by the connecting plate 223 to pass through the turning point, the wire releasing head 234 can rotate adaptively to reduce the bending angle of the copper wire, thereby avoiding the situation that the copper wire released by the wire releasing head 234 is broken due to too large an angle.

[0055] Considering that when the height of the wire releasing head 234 remains unchanged, only the copper wire released in the first circle when the wire pulling plate 231 moves along the "O"-shaped trajectory can be attached to the wall surface of the generator stator core. The copper wire released during the subsequent circular motion of the wire pulling plate 231 will be stacked on the copper wire released in the first circle. Since the released copper wire cannot be attached to the wall surface of the generator stator core, the distance between the formed coil and the wall surface of the generator stator core is relatively large, resulting in the loosening of the coil.

[0056] Therefore, it is necessary to adjust the height of the wire releasing head 234, such as Figure 6 、 Figure 7 、 Figure 9As shown, the reciprocating member 22 further includes a second screw shaft 224. One end of the top of the second screw shaft 224 passes through the connecting plate 223 and is rotationally connected to the slider 2212. The second screw shaft 224 is threadedly connected to the rotational connection portion. A second chute 2213 is formed in the slider 2212. One end of the top of the second screw shaft 224 is located in the second chute 2213 and is slidably connected to the inner wall of the second chute 2213 up and down. One end of the bottom of the second screw shaft 224 is connected to the wire pay-off head 234. When the connecting plate 223 drives the wire pulling plate 231 through the turning point, the rotational connection portion between the connecting plate 223 and the slider 2212 will rotate. Since one end of the top of the second screw shaft 224 can only slide up and down along the second chute 2213, the rotational connection portion will drive the second screw shaft 224 to move up when rotating. Furthermore, the second screw shaft 224 can drive the wire pay-off head 234 to move up, so that the copper wire released during each circular motion is not at the same height, thereby ensuring that the copper wires will not be stacked and can fit on the wall surface of the generator stator core, and preventing the occurrence of coil loosening on the wall surface.

[0057] Specifically, a top rod 2341 is provided at the top of the wire pay-off head 234. One end of the top of the top rod 2341 is inserted and matched with the bottom of the connecting cylinder 233. A connecting arm 2342 is sleeved on the surface of the top rod 2341. The top rod 2341 is connected to one end of the bottom of the second screw shaft 224 through the provided connecting arm 2342. By setting the top rod 2341 to be inserted and matched with the connecting cylinder 233 and setting the connecting arm 2342 to be connected to the plug rod 2241, it can be ensured that the wire pay-off head 234 can both rotate and be driven by the second screw shaft 224 to move up synchronously. Further, the second screw shaft 224 is inserted and matched with a plug rod 2241. A slot 2343 is correspondingly formed on the surface of the connecting arm 2342. One end of the plug rod 2241 is inserted and matched with the slot 2343. By setting the insertion and matching method, the plug rod 2241 is pulled out and removed from the second screw shaft 224, so that the plug rod 2241 is disengaged from the slot 2343, and the connection between the wire pay-off head 234 and the second screw shaft 224 can be released, thus facilitating the disassembly of the wire pay-off head 234 for operations such as threading.

[0058] In summary, as Figure 10As shown, during the process of the driving rod 211 driving the reciprocating plate 221 to reciprocate along the reciprocating groove 212, the reciprocating plate 221 drives the connecting plate 223 through the slider 2212, and then drives the wire pulling member 23 to move along the hanging plate 222 through the connecting plate 223. Since the hanging plate 222 is of an "O" - shaped structure, the displacement trajectory of the wire pulling member 23 is an "O" - shaped trajectory around the generator stator core, as shown by the closed arrow curve a. Thus, it is convenient for the wire released by the wire pulling member 23 to wind around the surface of the generator stator core to form a coil. Additionally, when the connecting plate 223 drives the wire pulling plate 231 to pass through the turning point, the rotating connection part between the connecting plate 223 and the slider 2212 will rotate. Since the top end of the second screw shaft 224 can only slide up and down along the second chute 2213, the rotating connection part will drive the second screw shaft 224 to move upward when rotating, as shown by the arrow b. Furthermore, the second screw shaft 224 can drive the wire releasing head 234 to move upward, so that the copper wires released during each circular motion are not at the same height, thereby ensuring that the copper wires will not overlap and can adhere to the wall surface of the generator stator core, avoiding the situation of coil loosening.
