Description

Technical Field

[0001] This application relates to the field of bending devices, and more particularly to a bending device for interphase insulation paper of a flat wire motor. Background Technology

[0002] A flat-wire motor is an AC motor that uses insulated copper wire with a rectangular cross-section as the winding conductor. A flat-wire motor mainly consists of a rotor, stator, and reducer. The stator is the stationary component of the motor, typically composed of coils wound with copper wire, and is fixed in place within the motor housing. Its main function is to generate a magnetic field, driving the rotor to rotate and completing the motor's operation; it is one of the core components of a flat-wire motor. Because the stator windings of a flat-wire motor are wound in different phases, a clear potential difference exists between the phase windings after energization. Therefore, interphase insulation paper is needed between the phases to block electrical conduction between them.

[0003] In the traditional processing of phase-to-phase insulation paper for flat-wire motors, the bending of the insulation paper is usually done manually, relying on the worker's experience and simple tools such as creasing tools and scissors to creasing and cut each sheet of insulation paper. This process depends heavily on the worker's skill level, is quite cumbersome, and the precision of manual operation is difficult to guarantee. Significant differences in operation between different workers result in inconsistent creasing depths and cutting dimensions of the insulation paper, which in turn affects the insulation performance of the motor.

[0004] In view of the aforementioned technologies, the inventors believe that a bending device is needed to improve the bending accuracy of interphase insulating paper. Utility Model Content

[0005] To improve the bending accuracy of interphase insulation paper, this application provides a bending device for interphase insulation paper of flat wire motors.

[0006] The bending device for interphase insulation paper of a flat wire motor provided in this application adopts the following technical solution: A bending device for interphase insulation paper of a flat wire motor includes a frame, a creasing mechanism mounted on the top surface of the frame for creasing the interphase insulation paper, a leveling mechanism arranged on one side of the creasing mechanism for driving the interphase insulation paper to be parallel, and a cutting mechanism arranged on the side of the creasing mechanism opposite to the leveling mechanism for cutting the interphase insulation paper. The creasing mechanism includes a support seat vertically arranged on the top surface of the frame, a cutter wheel assembly rotatably mounted on the support seat, and a drive assembly for driving the cutter wheel assembly to rotate. The cutter wheel assembly has a creasing protrusion corresponding to the creasing of the interphase insulation paper and a creasing groove cooperating with the creasing protrusion. The rotation of the cutter wheel assembly drives the interphase insulation paper arranged on the cutter wheel assembly to slide towards the cutting mechanism.

[0007] By adopting the above technical solution, in the process of creasing the interphase insulation paper, the leveling mechanism is first set up to ensure that the interphase insulation paper remains flat during the transmission process. Then, through the cooperation between the creasing protrusion and the creasing groove in the cutter wheel assembly, the interphase insulation paper leaves a creasing mark on the surface as it passes through the cutter wheel assembly. At the same time, the interphase insulation paper is driven to move towards the cutting mechanism, and the cutting mechanism cuts the interphase insulation paper, thereby completing the creasing process of the interphase insulation paper. This helps to improve the bending accuracy of the interphase insulation paper and facilitates the subsequent installation of the interphase insulation paper in flat wire electronics.

[0008] Optionally, the cutter wheel assembly includes a first cutter wheel rotatably mounted on the support base and a second cutter wheel disposed at the bottom of the first cutter wheel. The first cutter wheel has the indentation protrusion ring and the second cutter wheel has the indentation groove. The first cutter wheel and the second cutter wheel rotate synchronously to drive the sliding of the interphase insulating paper.

[0009] By adopting the above technical solution, the specific structure of the cutter wheel assembly is disclosed. The first cutter wheel has an indentation protrusion ring and the second cutter wheel has an indentation groove. The synchronous rotation of the two can drive the interphase insulation paper to slide, thereby realizing the indentation operation on the interphase insulation paper. At the same time, in conjunction with other components of the indentation mechanism and the leveling mechanism and cutting mechanism in the overall device, the leveling, indentation and cutting of the interphase insulation paper are completed.

[0010] Optionally, the drive assembly includes a drive motor, a first transmission wheel connected to the output shaft of the drive motor, a second transmission wheel connected and cooperating with the first cutter wheel, and a transmission toothed belt connecting the first transmission wheel and the second transmission wheel.

[0011] By adopting the above technical solution, the specific structure of the drive assembly is disclosed. The drive motor of the drive assembly can stably drive the first cutter wheel to rotate through the first transmission wheel, the transmission toothed belt and the second transmission wheel, thereby driving the cutter wheel assembly to rotate to realize the indentation and conveying of the interphase insulating paper.

[0012] Optionally, the support base is further provided with a tensioning roller on the top surface of the cutter wheel assembly, and the interphase insulating paper is conveyed to the cutter wheel assembly via the tensioning roller.

[0013] By adopting the above technical solution, a tensioning roller is set on the top surface of the cutter wheel assembly, so that the interphase insulation paper is conveyed to the cutter wheel assembly through the tensioning roller. This can keep the interphase insulation paper taut during the conveying process, ensuring that the interphase insulation paper is flat during the creasing operation and improving the creasing quality.

[0014] Optionally, the support base is provided with two tension rollers, which are arranged in parallel.

[0015] By adopting the above technical solution, the arrangement of two parallel tensioning rollers can better keep the interphase insulation paper taut when it is fed to the cutter wheel assembly, thereby improving the indentation quality.

[0016] Optionally, the cutting mechanism includes a cutting base, a cutting blade slidably mounted on the cutting base for cutting interphase insulation paper, and a lifting drive for driving the cutting blade to move up and down; the cutting base has a cutting slot for the interphase insulation paper to pass through, and the cutting base has a cutting surface at the cutting slot that cooperates with the cutting blade.

[0017] By adopting the above technical solution, the specific structure of the cutting mechanism is disclosed. When cutting the interphase insulation paper after the creasing treatment, the interphase insulation paper after the creasing treatment is input through the cutting through slot, the cutting blade is driven to rise and fall by the lifting drive component, and the cutting of the interphase insulation paper is realized by the cooperation between the cutting blade and the cutting surface of the cutting base.

[0018] Optionally, the cutting blade has a cutting tip that is obliquely arranged along the centerline of the cutting blade.

[0019] By adopting the above technical solution, the cutting tip of the cutting blade, which is inclined and arranged along the center line, can improve the cutting effect on the interphase insulation paper, making the cutting more precise and efficient.

[0020] Optionally, the leveling mechanism includes a leveling base mounted on the top surface of the frame and a leveling component mounted on the top surface of the leveling base. The leveling base and the leveling component have a leveling gap for allowing interphase insulating paper to pass through. The leveling component includes two symmetrically arranged leveling blocks, each leveling block having a leveling portion extending in the direction away from the indentation mechanism.

[0021] By adopting the above technical solution, the specific structure of the leveling mechanism is disclosed. The leveling gap between the leveling base and the leveling component of the leveling mechanism allows the interphase insulation paper to pass through. The two symmetrical leveling blocks of the leveling component and the leveling part extending in the direction away from the indentation mechanism can level the interphase insulation paper, so that the interphase insulation paper remains parallel, which facilitates the subsequent indentation treatment of the interphase insulation paper.

[0022] Optionally, the leveling component has a waist-shaped hole, and the leveling component is connected and fixed to the leveling base by screws.

[0023] By adopting the above technical solution, the leveling component has a waist-shaped hole and is connected and fixed to the leveling base with screws. The installation position of the leveling component can be flexibly adjusted to meet the leveling requirements of different specifications of phase insulation paper, so that the phase insulation paper can better maintain a parallel state during the leveling process. The leveling component can also be disassembled and replaced according to the actual use.

[0024] Optionally, a cleaning mechanism for cleaning the surface of the interphase insulation paper is also included. The cleaning mechanism is arranged on the side of the leveling mechanism away from the indentation mechanism. The cleaning mechanism includes a cleaning base mounted on the top surface of the frame, two cleaning blocks arranged on the top surface of the cleaning base, and a clamping block for pressing the cleaning blocks against the cleaning base. The cleaning base has an arrangement slot for arranging the cleaning blocks and an installation through slot for the interphase insulation paper to pass through. There is a cleaning gap between the two cleaning blocks for arranging the interphase insulation paper.

[0025] By adopting the above technical solution, a cleaning mechanism is set in the bending device of the phase insulation paper of the flat wire motor, which can clean the surface of the phase insulation paper and avoid surface impurities from affecting subsequent processes such as creasing, leveling, and cutting. The cleaning mechanism is arranged on the side of the leveling mechanism away from the creasing mechanism, so that the phase insulation paper can be cleaned before entering the leveling mechanism. The cleaning base has a groove for arranging cleaning blocks and an installation through slot for the phase insulation paper to pass through. The cleaning gap between two cleaning blocks is used for the arrangement of phase insulation paper, which can effectively clean the phase insulation paper. The clamping block can press the cleaning block firmly on the cleaning base to ensure the stability of the cleaning effect.

[0026] In summary, this application includes at least one of the following beneficial technical effects: 1. A bending device for interphase insulation paper of a flat wire motor, wherein during the creasing process of the interphase insulation paper, a leveling mechanism is first used to ensure that the interphase insulation paper remains flat during transport. Then, through the cooperation between the creasing protrusion and the creasing groove in the cutter wheel assembly, the interphase insulation paper leaves a creasing mark on its surface as it passes through the cutter wheel assembly. Simultaneously, the interphase insulation paper is driven to move towards the cutting mechanism, and the cutting mechanism cuts the interphase insulation paper, thereby completing the creasing process of the interphase insulation paper. This device helps to improve the bending accuracy of the interphase insulation paper and facilitates its subsequent installation in the flat wire motor. 2. The leveling mechanism can level the interphase insulation paper, keeping it parallel to facilitate subsequent indentation treatment. The leveling component has a slotted hole and is fixed to the leveling base with screws, allowing for flexible adjustment of the installation position to meet the leveling requirements of different specifications of interphase insulation paper. This ensures that the interphase insulation paper maintains a parallel state better during the leveling process. The leveling component can also be disassembled and replaced according to actual usage. 3. The cleaning mechanism can clean the surface of the interphase insulation paper, preventing surface impurities from affecting subsequent processes such as embossing, leveling, and cutting.

The top surface of the clamping block 53 is vertically provided with a clamping screw 531. The clamping effect of the clamping block 53 on the cleaning block 52 is changed by the cooperation between the clamping screw 531 and the clamping nut 514.

[0040] Reference Figure 3 and Figure 4 The leveling mechanism 3 ensures that the interphase insulation paper output from the cleaning mechanism 5 is smoothly conveyed to the creasing mechanism 2 for creasing. The leveling mechanism 3 includes a leveling base 31 mounted on the top surface of the frame 1 and a leveling component 32 mounted on the top surface of the leveling base 31. A leveling gap 33 is provided between the leveling base 31 and the leveling component 32 for the interphase insulation paper to pass through. To accommodate interphase insulation paper of different widths, the leveling component 32 includes two symmetrically arranged leveling blocks 321, each with a leveling portion 3211 extending away from the creasing mechanism 2. To facilitate adjustment of the distance between the two leveling blocks 321, the leveling blocks 321 have oblong holes 3212 and are fixed to the leveling base 31 by screws.

The first cutter wheel 221 has a creasing protrusion 2211 corresponding to the creasing of the interphase insulating paper, and the second cutter wheel 222 has a creasing groove 2221 that cooperates with the creasing protrusion 2211. The first cutter wheel 221 and the second cutter wheel 222 rotate synchronously, thereby driving the interphase insulating paper to slide towards the cutting mechanism 4. The drive assembly 23 includes a drive motor 231, a first drive wheel 232 connected to the output shaft of the drive motor 231, a second drive wheel 233 connected to the first cutter wheel 221, and a drive toothed belt 234 connecting the first drive wheel 232 and the second drive wheel 233.

[0042] Reference Figure 1 and Figure 7 The support base is provided with two tension rollers 24 on the top surface of the cutter wheel assembly 22. The two tension rollers 24 are arranged in parallel. After the phase insulation paper is output from the leveling mechanism 3, it is conveyed to the cutter wheel assembly 22 through the tension rollers 24 for indentation treatment.

To facilitate the cutting of the interphase insulation paper, the cutting blade 42 has a cutting tip 421, which is inclined at the centerline of the cutting blade 42. When the interphase insulation paper is conveyed to the cutting groove 411, the lifting drive 43 drives the cutting blade 42 to descend, so that the cutting tip 421 of the cutting blade 42 first cooperates with one side of the interphase insulation paper, thereby completing the cutting of the interphase insulation paper. In this embodiment, the lifting drive component 43 is a lifting cylinder.

[0044] Reference Figure 1 and Figure 8 A leveling mechanism 3 is also provided between the cutting mechanism 4 and the creasing mechanism 2, which helps to improve the cutting accuracy of the subsequent interphase insulation paper.

[0045] The implementation principle of the bending device for interphase insulation paper of a flat wire motor according to an embodiment of this application is as follows: During the bending process of the interphase insulation paper, the interphase insulation paper is first fed into the bending device of the interphase insulation paper of the flat wire motor through the cleaning mechanism 5, and the surface of the interphase insulation paper is cleaned by the cleaning mechanism 5. Then, through the setting of the leveling mechanism 3, the interphase insulation paper is kept flat during the transmission process. Then, through the cooperation between the indentation protrusion ring 2211 on the first cutter wheel 221 and the indentation groove 2221 on the second cutter wheel 222 in the indentation mechanism 2, the interphase insulation paper is indented. At the same time, the first cutter wheel 221 and the second cutter wheel 222 rotate to drive the interphase insulation paper to slide towards the cutting mechanism 4. Finally, the cutting mechanism 4 cuts the indented interphase insulation paper, thereby completing the bending process of the interphase insulation paper, improving the bending accuracy of the interphase insulation paper, and facilitating the subsequent installation of the interphase insulation paper in the flat wire motor.
