Description
Technical Field
[0001] This utility model relates to the field of stator manufacturing, and in particular to an automatic folding and insertion device for motor stator insulation paper. Background Technology
[0002] During the manufacturing process of electric motors, insulating paper needs to be inserted into the stator slots to achieve electrical insulation between the coils and the stator core. In existing technologies, the insertion of insulating paper is mainly accomplished manually, using semi-automatic or fully automated equipment.
[0003] Manual operation: The traditional method relies on workers to manually fold the insulating paper and insert it into the stator slot. The process is simple but inefficient.
[0004] Semi-automated equipment: Some equipment uses robotic arms or push rod mechanisms to manually push the insulating paper into the stator slot. This type of equipment typically includes a paper feeding mechanism, a folding mechanism, and an insertion mechanism. The paper feeding mechanism transports the insulating paper to the designated position, the folding mechanism pre-folds the insulating paper using a mold or robotic arm, and the insertion mechanism uses push rods or pneumatic devices to push the folded insulating paper into the stator slot.
[0005] Fully automated equipment: Some advanced equipment achieves fully automatic operation through servo motors and control systems, and is equipped with automatic paper feeding, folding and insertion modules. The stator is positioned by a rotating platform, and the insulating paper is conveyed by a conveyor belt and inserted into the slot by a push rod.
[0006] However, it still has the following drawbacks: poor adaptability to different stator specifications; lack of effective protection for paper, the insertion action may cause paper to tear or misalign, affecting insulation performance; and inability to accurately position the rotation angle of the stator according to the stator specifications, resulting in insertion deviation or insufficient equipment stability.
[0007] Therefore, it is necessary to further improve the automatic folding and insertion device for the motor stator insulation paper. Utility Model Content

An insertion component is installed on the telescopic end of the telescopic component. The telescopic component is slidably connected to the L-shaped frame through a limiting component.
[0010] The rotating disk is rotatably mounted on the rear surface of the L-shaped frame via its own rotating shaft. A rotating assembly is installed at the front end of the rotating shaft of the rotating disk, and an inner support clamp is provided on the rear surface of the rotating disk. A drive assembly and a positioning assembly are installed on the L-shaped frame. The drive assembly is connected to the rotating assembly, and the positioning assembly is located above the rotating assembly.
[0011] The positioning component locks the rotating disk when the insertion component is in operation, and releases the rotating disk after insertion to cooperate with the stepping rotation of the drive component.
[0012] Preferably, the telescopic assembly includes a mounting frame, an electrically controlled push rod 1, and a support block. The support block and the electrically controlled push rod 1 are mounted on the mounting frame. The support block is connected to the outer side of the electrically controlled push rod 1. The telescopic end of the electrically controlled push rod 1 is located in the extension hole of the mounting frame. The telescopic end of the electrically controlled push rod 2 is connected to the mounting frame.
[0013] Preferably, the insertion assembly includes a paper inserter and a connector. The connector is mounted on the telescopic end of the electrically controlled push rod by its own locking screw. The paper inserter is located on the rear side of the connector, and the outer side of the paper inserter is covered with flexible silicone.
[0014] Preferably, the through hole and the paper feed slot are formed on the upper surface of the L-shaped frame, the paper insertion slot is set on the rear surface of the L-shaped frame, the central axis of the paper insertion slot, the through hole and the paper feed slot corresponds to the axis of the electric control push rod, and the axis of the paper insertion rod coincides with the center line of the paper insertion slot.
[0015] Preferably, the limiting component includes a limiting hole and a limiting rod. The limiting hole is opened on the upper surface of the L-shaped frame, and the limiting rod is slidably connected in the limiting hole and installed on the lower side of the mounting frame.
[0016] Preferably, the rotating assembly includes a positioning disk and a driven gear. The positioning disk is located behind the driven gear, and the positioning disk and the driven gear are mounted on the rotating shaft of the rotating disk. The outer surface of the positioning disk has a plurality of positioning grooves evenly distributed along the circumference.
[0017] Preferably, the positioning component includes an electrically controlled push rod three and a positioning block. The electrically controlled push rod three is mounted on an L-shaped frame via a fixing bracket, and the positioning block is located at the telescopic end of the electrically controlled push rod three. The shape of the positioning block is adapted to the positioning groove on the positioning plate.
[0018] Preferably, the drive assembly includes a drive gear, a stepper motor, and a motor frame. The stepper motor is mounted on an L-shaped frame via the motor frame, and the drive gear is mounted on the output shaft of the stepper motor. The drive gear meshes with the driven gear.
[0019] The working principle and usage principle of this utility model are as follows: an L-shaped frame is installed on the main body of the stator slot paper machine, and an insulating paper folding mechanism and a cutting mechanism corresponding to the shape of the motor stator slot are installed on the L-shaped frame. The insulating paper folding mechanism and the cutting mechanism are installed at the paper feed slot, ensuring that the insulating paper enters the insulating paper folding mechanism and the cutting mechanism from below the L-shaped frame through the paper feed slot.
[0020] The stator is placed on the inner support clamp for fixation.

[0025] 2. The support block can support and fix the end of the electric control push rod, ensuring that the electric control push rod runs smoothly. When the electric control push rod is running, it can ensure that the paper insertion rod is located on the central axis of the paper insertion slot, through hole and paper feed slot, ensuring that the paper insertion rod can drive the insulating paper to be accurately inserted into the stator slot.

Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

Figure 1The orientations or positional relationships shown are for the convenience of describing this application and simplifying the description only, and are not intended to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this application. When a feature is referred to as "set", "fixed", or "connected" to another feature, it can be directly set, fixed, or connected to the other feature, or it can be indirectly set, fixed, or connected to the other feature.
[0035] Please see Figure 1-5 This utility model provides a technical solution: an automatic folding and inserting device for motor stator insulation paper, including an L-shaped frame 1 and a rotating disk 13. The L-shaped frame 1 is provided with a through hole 5, a paper feed slot 8 and a paper insertion slot 9. An electrically controlled push rod 7 is installed in a U-shaped frame provided on the front side of the lower surface of the L-shaped frame 1. Its telescopic end passes through the through hole 5 and is connected to the telescopic component 4 on the upper side of the L-shaped frame 1. An insertion component 2 is installed on the telescopic end of the telescopic component 4. The telescopic component 4 is slidably connected to the L-shaped frame 1 through a limiting component 6.
[0036] Specifically, the L-shaped frame 1 is installed on the main body of the stator slot paper machine. The L-shaped frame 1 is equipped with an insulating paper folding mechanism and a cutting mechanism corresponding to the shape of the motor stator slot. The insulating paper folding mechanism and the cutting mechanism are installed at the paper feed slot 8 to ensure that the insulating paper enters the insulating paper folding mechanism and the cutting mechanism from below the L-shaped frame 1 through the paper feed slot 8.
[0037] Specifically, the extension and retraction of the electric push rod 2 7 can drive the insertion component 2 and the telescopic component 4 to rise and fall, ensuring that the height of the insertion component 2 and the telescopic component 4 is consistent with the height of the stator slot, so as to adapt to different models of stators. The limit component 6 limits the telescopic component 4 to ensure the parallelism of the telescopic component 4 with the L-shaped frame 1 when it rises and falls.
[0038] The rotating disk 13 is rotatably mounted on the rear surface of the L-shaped frame 1 via its own rotating shaft. A rotating assembly 11 is mounted on the front end of the rotating shaft of the rotating disk 13. An inner support clamp 10 is provided on the rear surface of the rotating disk 13. A drive assembly 3 and a positioning assembly 12 are mounted on the L-shaped frame 1. The drive assembly 3 is connected to the rotating assembly 11, and the positioning assembly 12 is located above the rotating assembly 11.
[0039] The positioning component 12 locks the rotating disk 13 when the insertion component 2 is in operation, and releases the rotating disk 13 after insertion to cooperate with the stepping rotation of the drive component 3.
[0040] Specifically, the rotating shaft of the rotating disk 13 is mounted on the L-shaped frame 1 through bearings to ensure the smoothness of the rotation of the rotating disk 13 and prevent the rotating disk 13 from becoming eccentric during rotation. The drive component 3 can drive the rotating component 11 to rotate, thereby driving the rotating disk 13 to rotate. The positioning component 12 can position the rotating component 11 to prevent the rotating disk 13 from rotating off-center and improve the accuracy of inserting the insulating paper. The inner support clamp 10 can provide inner support and fixation for stators of different models.
[0041] Furthermore, the telescopic assembly 4 includes a mounting frame 401, an electrically controlled push rod 402, and a support block 403. The support block 403 and the electrically controlled push rod 402 are mounted on the mounting frame 401. The support block 403 is connected to the outer side of the electrically controlled push rod 402. The telescopic end of the electrically controlled push rod 402 is located in the extension hole of the mounting frame 401. The telescopic end of the electrically controlled push rod 7 is connected to the mounting frame 401.
[0042] Specifically, the support block 403 can support and fix the end of the electric push rod 402 to ensure that the electric push rod 402 runs smoothly. The operation of the electric push rod 7 can drive the mounting frame 401 and the electric push rod 402 to rise and fall.
[0043] Furthermore, the insertion component 2 includes a paper insertion rod 201 and a connector 202. The connector 202 is mounted on the telescopic end of the electronically controlled push rod 402 by its own locking screw. The paper insertion rod 201 is located on the rear side of the connector 202, and the outer side of the paper insertion rod 201 is covered with flexible silicone.
[0044] Specifically, when the electrically controlled push rod 402 extends or retracts, it can drive the paper insertion rod 201 to move. The paper insertion rod 201 drives the folded insulating paper through the paper insertion slot 9 and inserts it into the stator slot. The paper insertion rod 201 can be replaced according to the shape and length of the stator slot to ensure that the paper insertion rod 201 can fit the stator slot. The flexible silicone on the outside of the paper insertion rod 201 is used to protect the insulating paper and reduce the insertion resistance.
[0045] Furthermore, the through hole 5 and the paper feed slot 8 are formed on the upper surface of the L-shaped frame 1, and the paper insertion slot 9 is set on the rear surface of the L-shaped frame 1. The central axis of the paper insertion slot 9, the through hole 5 and the paper feed slot 8 corresponds to the axis of the electric control push rod 402, and the axis of the paper insertion rod 201 coincides with the center line of the paper insertion slot 9.
[0046] Specifically, when the electric control push rod 402 is running, it can ensure that the paper insertion rod 201 is located on the central axis of the paper insertion slot 9, the through hole 5 and the paper feed slot 8, so that the paper insertion rod 201 can drive the insulating paper to be accurately inserted into the stator slot. The paper insertion slot 9 is set so that the stator slot on the lower side of the stator corresponds to the paper insertion rod 201.
[0047] Furthermore, the limiting component 6 includes a limiting hole 601 and a limiting rod 602. The limiting hole 601 is opened on the upper surface of the L-shaped frame 1, and the limiting rod 602 is slidably connected in the limiting hole 601. The limiting rod 602 is installed on the lower side of the mounting bracket 401.
[0048] Specifically, when the mounting bracket 401 is raised or lowered, it can drive the limiting rod 602 to slide within the limiting hole 601. The cooperation of the limiting rod 602 with the limiting hole 601 restricts the raising and lowering direction and range of the mounting bracket 401, ensuring the stability of the movement of the mounting bracket 401.
[0049] Furthermore, the rotating assembly 11 includes a positioning disk 1101 and a driven gear 1102. The positioning disk 1101 is located on the rear side of the driven gear 1102. The positioning disk 1101 and the driven gear 1102 are mounted on the rotating shaft of the rotating disk 13. The outer surface of the positioning disk 1101 has a plurality of positioning grooves evenly distributed along the circumference.
[0050] Specifically, the positioning disk 1101 and the driven gear 1102 are both keyed to the rotating shaft of the rotating disk 13, ensuring that the driven gear 1102 can drive the rotating disk 13 to rotate when it rotates. The positioning disk 1101 can be replaced with a positioning disk corresponding to the number of stator slots, ensuring that the number and distribution angle of the positioning slots correspond to the stator slots, so as to ensure accurate positioning.
[0051] Furthermore, the positioning component 12 includes an electrically controlled push rod 1201 and a positioning block 1202. The electrically controlled push rod 1201 is mounted on the L-shaped frame 1 by a fixing bracket. The positioning block 1202 is located at the telescopic end of the electrically controlled push rod 1201. The shape of the positioning block 1202 is adapted to the positioning groove on the positioning disk 1101.
[0052] Specifically, the extension and retraction of the electric push rod 1201 can drive the movement of the positioning block 1202. When inserting insulating paper into the stator slot, the positioning block 1202 can be inserted into the positioning slot of the positioning disk 1101, which can lock the positioning disk 1101 and the rotating disk 13. After the insulating paper insertion is completed, the positioning block 1202 exits the positioning slot of the positioning disk 1101, releasing the positioning disk 1101 and the rotating disk 13.
[0053] Furthermore, the drive assembly 3 includes a drive gear 301, a stepper motor 302, and a motor frame 303. The stepper motor 302 is mounted on the L-shaped frame 1 via the motor frame 303. The drive gear 301 is mounted on the output shaft of the stepper motor 302, and the drive gear 301 meshes with the driven gear 1102.
[0054] Specifically, when the stepper motor 302 is running, it can drive the rotation of the drive gear 301, which in turn drives the rotation of the driven gear 1102, thereby driving the rotating disk 13 to rotate step by step. The stepper motor 302 sets a corresponding rotation angle according to the tooth ratio of the drive gear 301 and the driven gear 1102 to ensure that the rotation angle of the rotating disk 13 is consistent with the angle of the two adjacent stator slots, so that the stator slots correspond to the paper insertion rod 201.
[0055] It is worth noting that the input terminals of stepper motor 302, electric control push rod 1 402, electric control push rod 2 7, and electric control push rod 3 1201 are electrically connected to the output terminal of the main controller of the stator slot paper machine, ensuring that the main controller of the stator slot paper machine can control the rotation angle of stepper motor 302 and control the extension and retraction of electric control push rod 1 402, electric control push rod 2 7, and electric control push rod 3 1201.
[0056] Stepper motor 302 can be Mingzhi 57BYGH-250-4E model; electric control actuator 1 402 can be Limtech LAP-20-200-24 model; electric control actuator 2 7 can be Limtech LAP-15-100-12-L model, with built-in self-locking mechanism, which can maintain the position by mechanical locking or power failure after extending to a specified length; electric control actuator 3 1201 can be Limtech LAP-10-50-12 model.
[0057] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this application, and are not intended to limit them. Although this application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this application.
