Description

Technical Field

[0001] This invention relates to the field of stator slot paper insertion technology, and in particular to a stator slot paper insertion device for motor stator cores. Background Technology

[0002] In the field of motor manufacturing, the insulation treatment of the stator core is a key process to ensure motor performance and safety, and the stator slot insulation paper (i.e., slot insulation) is an essential part. The main function of the slot insulation paper is to isolate the stator core from the coil windings, preventing inter-turn short circuits or short circuits to ground, which directly affect the service life and operational stability of the motor.

[0003] Current stator paper insertion operations mainly rely on manual operation or semi-automatic mechanical equipment. In the traditional manual operation mode, workers need to manually cut the insulation paper, fold it into shape, and then insert it into the stator slots one by one. This method is not only labor-intensive and inefficient, but also greatly affected by human factors, making it difficult to ensure the consistency of the insertion depth and position of the insulation paper. It is very easy to have quality problems such as insulation paper damage, wrinkles, or incomplete insertion, resulting in safety hazards to the motor.

[0004] Therefore, developing a high-efficiency stator slot paper insertion device is of great significance for breaking through the efficiency bottleneck of traditional manual or semi-automatic paper insertion processes and promoting the overall manufacturing efficiency of motor stator cores. Summary of the Invention

[0011] As a further embodiment of the present invention: the top outer wall of the frame is equipped with an unwinding mechanism and a moving mechanism for conveying paper tape. The unwinding mechanism includes a mounting plate welded to the top of the frame and a winding shaft rotatably connected to the side of the mounting plate. A sleeve for winding the paper tape is inserted into the outer circumference of the winding shaft.

[0012] As a further embodiment of the present invention: the moving mechanism includes a conveyor frame welded to the outer wall of one side of the mounting plate and two sets of conveyor rollers rotatably connected between the inner walls of the two sides of the conveyor frame. The outer circumference of the conveyor rollers is wrapped with friction strips for adjusting the distance between the two sets of conveyor rollers. A conveyor motor for driving the conveyor rollers is fixed to the outer wall of one side of the conveyor frame.

[0013] As a further embodiment of the present invention: a sliding frame is slidably connected to the through hole on the side of the frame, and the inner wall of the connecting frame and the inner wall of the sliding frame are rotatably connected by the same connecting rod.

[0016] Compared with the prior art, the present invention provides a stator slot paper insertion device for motor stator core, which has the following advantages: 1. Through a planetary gear mechanism consisting of a drive motor, sun gear, planetary gears, and a gear ring, and with the limiting action of positioning pin one and positioning pin two, the working modes can be flexibly switched. It can either allow the support component to revolve around the sun gear to transport multiple stator bodies one by one to the paper insertion station for continuous feeding, or drive the stator body to rotate while the gear ring is in the limiting position, thereby inserting paper into multiple paper insertion slots along the stator's circumference one by one.

[0017] 2. A shaping mechanism consisting of a shaping punch, a shaping die, and a drive assembly is provided. This mechanism can compress the flat paper strip into a shape that fits the stator slot before paper insertion, facilitating smooth insertion of the paper strip into the slot and preventing paper jams. Simultaneously, the blades and contact plates driven by the electric telescopic rod ensure precise cutting of the paper strip after it has been fed into position.

[0018] 3. A floating support assembly consisting of a guide rod, a spring, and a positioning plate is installed on the support plate. In the initial state, the spring force causes the positioning plate to bulge out, and the stator body can slide quickly along the positioning plate. The inner diameter of the positioning plate is used to initially position the stator, solving the problem of difficult manual placement and alignment.

[0019] 4. After the paper is inserted, the pressure bar presses down to push the pressure plate to move down against the spring resistance, so that the top of the positioning plate avoids the pressure plate. Then, the bottom of the pressure plate directly presses the paper strip protruding from the stator body into the gap between the positioning plate and the bottom of the stator.

[0020] The parts of this device not covered herein are the same as or can be implemented using existing technologies. This invention has a simple structure and is easy to operate. Attached Figure Description

[0023] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0024] Example 1: A paper insertion device for stator slots of motor stator core, such as... Figures 1 to 11As shown, the system includes an operating platform 1 with a controller 10 mounted on its side. A rotating ring 16 is rotatably connected to the inner wall of a through hole at the top of the operating platform 1 via a bearing. A turntable 46 is screwed to the outer wall of the top of the rotating ring 16. Multiple sets of support members for placing the stator body 18 are mounted on the surface of the turntable 46 by rotation. Each support member includes a rotating shaft 23 rotatably connected to the surface of the turntable 46 and a support plate 24 fixed to the top of the rotating shaft 23 by a pin. The support plate 24 is used to support the stator body 18. A guide rod 26 is slidably connected to a through hole inside the support plate 24. A pressure plate 21 is fixed to the bottom of the guide rod 26 by screws. The two ends of a spring 25 fitted into the outer wall of the guide rod 26 are respectively fixed to the bottom of the support plate 24 and the top of the pressure plate 21. A positioning plate 4 is fixed to the top of the guide rod 26 by screws. A storage groove that matches the outer diameter of the positioning plate 4 is opened inside the support plate 24. When paper insertion is required on the stator body 18, the stator body 18 is first loaded. During loading, the positioning plate 4, which is adapted to the inner diameter of the stator body 18, can be fixed on the top of the guide rod 26 in advance. In the initial state, the spring force of the spring 25 makes the positioning plate 4 protrude from the upper surface of the support plate 24. Therefore, during the loading process, the bottom of the stator body 18 can be inserted along the protruding positioning plate 4. The positioning plate 4 is used to initially position the stator body 18 to ensure the stability of the stator body 18 relative to the support plate 24.

[0025] The top outer wall of the operating table 1 is fixed with a frame 7 by bolts. The top outer wall of the frame 7 is equipped with an unwinding mechanism and a moving mechanism for conveying the paper tape 36. The unwinding mechanism includes a mounting plate 14 welded to the top of the frame 7 and a winding shaft 31 rotatably connected to the side of the mounting plate 14. A sleeve 37 for winding the paper tape 36 is inserted into the outer circumference of the winding shaft 31. The moving mechanism includes a conveying frame 32 welded to one side outer wall of the mounting plate 14 and two sets of conveying rollers 34 rotatably connected between the inner walls of the two sides of the conveying frame 32. The outer circumference of the conveying rollers 34 is wrapped with friction strips 35 for adjusting the distance between the two sets of conveying rollers 34. A conveying motor 33 is fixed to one side outer wall of the conveying frame 32 by screws. The output end of the conveying motor 33 is connected to one end of the conveying roller 34 through a coupling. The sleeve 37 can be used to wind the paper tape 36. When installation is required, the sleeve 37 is fixed to the outer circumference of the winding shaft 31 by insertion using the friction between the sleeve 37 and the winding shaft 31. The outer circumference of the winding shaft 31 is integrally formed with a limiting plate for abutting and limiting the side of the paper tape 36. When the paper tape 36 needs to be conveyed, one end of the paper tape 36 is placed in the gap between the two friction strips 35. The two sets of friction strips 35 apply a certain friction force to both sides of the paper tape 36. When the two sets of conveying motors 33 drive the corresponding conveying rollers 34 to rotate in opposite directions at the same speed, the paper tape 36 is conveyed under the action of friction.

[0026] The frame 7 has a through hole on its side that is slidably connected to a sliding frame 41. One end of the sliding frame 41 is fixed to a drive seat 42 by screws. A shaping punch 38 is fixed to one side of the inner wall of the drive seat 42 by screws. An intermediate plate 40 is welded to one side of the inner wall of the mounting plate 14. A shaping die 39 that works with the shaping punch 38 is fixed to the bottom of the intermediate plate 40 by screws. As the paper tape 36 is continuously fed until it moves to the gap between the shaping punch 38 and the shaping die 39, the shaping punch 38 and the shaping die 39 shape the paper tape 36 by squeezing it through the sliding frame 41 along the side of the frame 7. After being shaped, the paper tape 36 is easy to insert into the paper slot on the stator body 18.

[0027] The top outer wall of the operating table 1 is fixed with a U-shaped frame 47 by bolts. The top outer wall of the U-shaped frame 47 is fixed with an electric telescopic rod 8 by screws. The output end of the electric telescopic rod 8 is fixed with a connecting frame 12. The inner wall of the connecting frame 12 and the inner wall of the sliding frame 41 are rotatably connected by the same connecting rod 13. The connecting frame 12 can be driven to move up and down by the electric telescopic rod 28. The connecting rod 13 can convert the up and down movement of the connecting frame 12 into the lateral movement of the sliding frame 41 relative to the frame 7, so that the sliding frame 41 indirectly drives the shaping punch 38 to move and cooperate with the shaping die 39 to shape the paper tape 36.

[0028] An electric telescopic rod 27 is fixed to one side of the outer wall of the frame 7 by screws. A drive plate 30 is fixed to the output end of the electric telescopic rod 27 by pins. A blade 44 is fixed to the side of the drive plate 30 by screws. A contact plate 43 that works with the blade 44 is fixed to the bottom of the molding die 39 by screws. After the paper tape 36 is shaped, the moving mechanism moves the shaped paper tape 36 so that the shaped paper tape 36 is inserted longitudinally into the paper insertion slot on the stator body 18 that is aligned with it. When the bottom of the paper tape 36 is inserted and fits against the upper surface of the positioning plate 4, the electric telescopic rod 3 27 drives the blade 44 to move laterally so that the other side of the paper tape 36 touches the surface of the contact plate 43. Then, the pressure of the blade 44 on the surface of the paper tape 36 is used to cut it.

[0029] The top inner wall of the operating table 1 is fixed with a drive motor 15 by screws. The output end of the drive motor 15 is fixed with a sun gear 9 by a pin. The outer circumference of the rotating shaft 23 is connected with a planet gear 22 that meshes with the sun gear 9 by a key. The top outer wall of the operating table 1 is fixed with a connecting plate 2 by screws. One end of the connecting plate 2 is fixed with a mounting base 20 by screws. The inner circumference of the mounting base 20 is rotatably connected with a gear ring 19 that meshes with the planet gear 22. The sun gear 9, the gear ring 19, and the planet gears 22 constitute a planetary gear mechanism. Therefore, when multiple support members are needed to feed the stator body 18 and move it one by one to the unwinding mechanism and the moving mechanism for paper insertion, the gear ring 19 can be limited relative to the mounting base 20, while ensuring that the rotating ring 16 can rotate freely relative to the operating table 1. Therefore, when the drive motor 15 drives the sun gear 9 to rotate, the multiple sets of planet gears 22 can revolve around the sun gear 9 while rotating on their own axis, ensuring that each set of support members can move to the unwinding mechanism and the moving mechanism for paper insertion. Meanwhile, since multiple paper insertion slots are distributed around the circumference of the stator body 18, when paper needs to be inserted into each slot one by one, the rotating ring 16 and the turntable 46 are limited, while ensuring that the gear ring 19 can rotate freely relative to the mounting base 20. Therefore, when the drive motor 15 drives the sun gear 9 to rotate, the planet gear 22 only stays at a fixed position to rotate, so that each set of paper insertion slots on the stator body 18 can perform paper insertion operations.

[0030] The toothed ring 19 has a positioning groove 17 on its outer circumference, and the number of positioning grooves 17 is consistent with the number of support members. The drive plate 30 has a positioning post 29 fixed on its side to cooperate with the positioning groove 17. When it is necessary to limit the toothed ring 19, the electric telescopic rod 27 can drive the drive plate 30 and the positioning post 29 to move laterally, so that the positioning post 29 is inserted into the corresponding positioning groove 17. The positioning post 29, in conjunction with the positioning groove 17, limits the toothed ring 19 relative to the mounting base 20. At the same time, since the positioning groove 17 has a certain depth, it can be ensured that when the positioning post 29 is inserted into the positioning groove 17, a certain distance is maintained between the blade 44 and the paper tape 36, so as to prevent the blade 44 from cutting the paper tape 36 after the positioning post 29 is inserted into the positioning groove 17.

[0031] The outer wall of the turntable 46 is fixed with an extension plate 45 by screws. The surface of the extension plate 45 is provided with a positioning hole 3. The bottom outer wall of the connecting frame 12 is fixed with a positioning post 28 that cooperates with the positioning hole 3. When it is necessary to limit the turntable 46, when the positioning hole 3 on the extension plate 45 is rotated to be in the position directly opposite the positioning post 28, the connecting frame 12 and the positioning post 28 are driven to move down by the electric telescopic rod 28 so that the positioning post 28 is inserted into the positioning hole 3. This can limit the turntable 46 and the rotating ring 16 relative to the operating table 1. At the same time, since the positioning post 28 has a certain length, while the rotating ring 16 and the turntable 46 are limited, the distance between the shaping punch 38 and the shaping die 39 is maintained, so as to prevent the shaping punch 38 from shaping the paper tape 36 when the positioning post 28 is inserted into the positioning hole 3.

[0032] Working principle: First, the positioning plate 4, which matches the inner diameter of the stator body 18, is fixed on the top of the guide rod 26. In the initial state, the spring force of the spring 25 causes the positioning plate 4 to protrude from the upper surface of the support plate 24. During feeding, the bottom of the stator body 18 is inserted along the protruding positioning plate 4. When using the positioning plate 4 for positioning, it is necessary to ensure that when the stator body 18 revolves to the moving mechanism and the unwinding mechanism, the paper insertion slot on the stator body 18 and the forming die 39 are aligned longitudinally. The drive motor 15 drives the sun gear 9 to rotate, which requires multiple support components to rotate. When the stator body 18 moves to the paper insertion station one by one, the positioning pin 29 is driven by the electric telescopic rod 3 27 to insert into the positioning groove 17 of the toothed ring 19 to limit the toothed ring 19 and ensure that the rotating ring 16 can rotate freely. At this time, the planetary gear 22 revolves around the sun gear 9 while rotating on its own axis, driving the support component to revolve and realize the station switching. When it is necessary to insert paper into multiple paper insertion slots on the same stator body 18 one by one, the positioning pin 28 is driven by the electric telescopic rod 28 to insert into the positioning hole 3 of the extension plate 45 to control the turntable 46 and the rotating ring 16. Limiting the position while ensuring the toothed ring 19 can rotate freely, the planetary gear 22 rotates in a step-by-step manner under the indirect drive of the drive motor 15, driving the stator body 18 on the support plate 24 to rotate to switch the paper insertion slot angle; the paper strip 36 on the sleeve 37 of the unwinding mechanism is conveyed forward by the friction force generated by the two sets of conveying rollers 34 and friction strips 35 rotating in opposite directions at the same speed. When the paper strip 36 moves to the gap between the shaping punch 38 and the shaping die 39, the electric telescopic rod 28 is connected by the connecting frame 12 and the connecting rod 13. The sliding frame 41 moves laterally, causing the shaping punch 38 to work with the shaping die 39 to squeeze and shape the paper strip 36. Finally, the shaped paper strip 36 is conveyed and inserted longitudinally into the paper insertion slot of the stator body 18 that is aligned with it. When the bottom of the paper strip 36 is inserted and fits against the upper surface of the positioning plate 4, the electric telescopic rod 3 27 drives the blade 44 to move laterally, so that the other side of the paper strip 36 touches the surface of the contact plate 43 and is cut off by pressure, thus completing one paper insertion operation. This cycle can realize continuous and automated stator slot paper insertion processing.

[0033] Example 2: A stator slot paper insertion device for a motor stator core, wherein to ensure paper insertion accuracy, such as... Figures 1 to 2 As shown, this embodiment makes the following additions based on embodiment 1: the top outer wall of the operating table 1 is fixed with a bracket 5 by bolts, the top outer wall of the bracket 5 is fixed with an electric telescopic rod 6 by bolts, the output end of the electric telescopic rod 6 is fixed with a pressure plate 48, and the bottom of the pressure plate 48 is fixed with a pressure rod 11 that works with the pressure plate 21 by screws; When the stator body 18 rotates to the bottom of the pressure plate 48 after the initial paper insertion, the pressure plate 48 and the pressure rod 11 are driven to move down by the electric telescopic rod 6. The pressure rod 11 first contacts the pressure plate 21 and then presses the pressure plate 21, so that the top of the positioning plate 4 and the bottom of the paper strip 36 gradually separate. Then the pressure plate 48 gradually moves down to the top of the paper strip 36 and presses down the part of the paper strip 36 that protrudes from the stator body 18, so that the protruding paper strip 36 fills the gap between the positioning plate 4 and the bottom of the stator body 18, ensuring the paper insertion effect.

[0034] Working principle: In terms of electrical control, the controller 10 controls the drive motor 15 to drive the sun gear 9 to rotate through a preset program. In conjunction with the electric telescopic rod 28 and the electric telescopic rod 327, the controller drives the positioning pin 128 and the positioning pin 29 to insert into the positioning hole 3 or the positioning groove 17, respectively. The controller intelligently switches the limiting state of the turntable 46 or the toothed ring 19 to achieve precise conversion between the support component's revolution feeding and the stator's self-converting groove. At the same time, the controller 10 links the conveyor motor 33 to drive the conveyor roller 34 to feed the paper by friction. In conjunction with the electric telescopic rod 28, the controller drives the shaping punch 38 through the connecting rod 13 to squeeze the paper strip 36 into shape. The controller also controls the electric telescopic rod 327 to push the blade 44 to cut the paper strip 36 laterally. Finally, the controller drives the pressure rod 11 through the electric telescopic rod 6 to press down the pressure plate 21, causing the positioning plate 4 to descend and completely press the protruding paper strip 36 into the stator groove.

Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
