Description

Technical Field

[0001] This invention relates to the field of stator manufacturing technology, specifically to a stator paper-making mechanism and its winding and embedding machine. Background Technology

[0002] In the stator of an electric motor, copper wire (enameled wire) is directly embedded into the slots of the stator core. To prevent a short circuit between the copper wire and the silicon steel core (which would break down the insulation layer of the enameled wire), an insulating material must be pre-insulated into the inner wall of the stator slot. This insulating material is usually insulating paper, and this process is called "insertion" or "paper insertion." In traditional manual or semi-automatic production, this process is done manually, which is inefficient and inconsistent. For example, Chinese Patent (Application No. 202311454224.5) discloses a paper-punching and wire-embedding integrated device for a slender stator, which includes a frame and a rotating table inside the frame. One side of the rotating table is a paper-punching station, and the other side is a wire-embedding station. Wire-embedding molds are provided on both sides of the rotating table, and a paper material library is provided integrated below the wire-embedding molds. However, as described, a large number of sensing modules and sensors are required to realize the automated paper-punching process, such as segmentation sensing blocks and origin sensors. However, these electronic sensors and PLC programs may have problems such as false triggering, delay, or electromagnetic interference. Therefore, a stator paper-punching mechanism and its winding and embedding machine based on a specific mechanical structure are designed. Summary of the Invention

Detailed Implementation

[0017] In the description of this invention, it should be understood that the terms "length," "width," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," and "outer," etc., indicating orientation or positional relationships, are based on the orientation or positional relationships shown in the accompanying drawings and are only for the convenience of describing this invention and simplifying the description, and do not 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 invention. The various embodiments of this invention are described in detail below with reference to the accompanying drawings.

[0018] Example 1 Please see Figures 1 to 13The present invention preferably provides a technical solution: a stator paper-pressing mechanism and its winding and embedding machine, comprising: a frame 2, a plate 111 disposed on the frame 2, a paper pressing assembly and a cutting assembly respectively mounted on the plate 111, and a paper tape conveying assembly and a cam drive mechanism respectively mounted on the front and rear sides of the plate 111; it also includes a feeding paper tube assembly disposed on the frame 2, the paper tape conveying assembly being placed between the plate 111 and the feeding paper tube assembly and respectively docking with the cutting assembly and the paper pressing assembly; a ratchet assembly is provided on the feeding paper tube assembly, a linkage transmission assembly is mounted on the cam drive mechanism, and a pawl actuation assembly is connected to the execution end of the linkage transmission assembly; when the cam drive mechanism is running, it is used to drive the cutting assembly, the paper pressing assembly, and the pawl actuation assembly to switch operations sequentially.

[0019] A paper-cutting mechanism for a paper-wrapping machine is provided, which precisely controls multiple actuators (cutter assembly, paper-pressing assembly, and pawl actuation assembly) to work in a predetermined sequence through a power source (cam drive mechanism) and ingenious mechanical design.

[0020] Specifically, such as Figure 1 , 3 As shown in Figures 4 and 5, the paper tape conveying assembly drives the paper strips to be conveyed and pass through the processing stations in sequence, that is, to dock with the corresponding cutting assembly and paper pressing assembly. Then, the cam drive mechanism runs, which can drive the cutting assembly and paper pressing assembly to reciprocate linearly in sequence. The corresponding cutting assembly extends forward to complete the cutting action of the paper tape. When the cutting assembly retracts to reset, the corresponding paper pressing assembly extends forward to press each cut paper tape into the feeding paper tube assembly in sequence. When the paper pressing assembly retracts to reset, the cutting assembly extends forward again. This reciprocating action is carried out in sequence. Under the further action of the linkage drive assembly, that is, when the paper pressing assembly retracts to reset and the cutting assembly extends forward, the pawl actuating assembly runs to move the ratchet disk assembly on the feeding paper tube assembly to change to the next pressing slot position. When the paper pressing assembly extends forward, the pawl actuating assembly extends forward, and the ratchet disk assembly is not moved. In this way, a certain length of paper tape is pressed into the slot of the corresponding feeding paper tube assembly in an orderly and precise manner, realizing the paper feeding process of the wrapping and embedding machine.

[0021] In this process, key actions (cutting, pressing, and pawing) are achieved through the linkage of cams and connecting rods, with specific motion trajectories and timing sequences, reducing potential problems such as false triggering, delays, or electromagnetic interference from electronic sensors and PLC programs. Furthermore, under the structural action of the cam-driven mechanism, specific actions are triggered by a designed specific rotation angle. This ensures that the actions of the "cutting assembly," "paper pressing assembly," and "pawl-pulling assembly" have a strict sequence and phase difference in time. This results in the "cutting assembly" cutting first, then the "paper pressing assembly" pressing the paper into the slot, and finally the "pawl-pulling assembly" driving the feeding paper tube assembly to switch positions.

[0022] Example 2 In another embodiment of the present invention, the feeding paper tube assembly includes a sleeve 312, a crossbar 113 is bolted to the upper part of the sleeve 312, the crossbar 113 is fixedly mounted on the frame 2 by locking assemblies 114 at both ends, and a support base 1016 is mounted at the bottom of the sleeve 312. A positioning seat 1015 is installed in the middle of the support base 1016, and a paper tube 311 mounted on the positioning seat 1015 is sleeved on the outer wall of the positioning seat 1015. The paper tube 311 is circumferentially arranged... The machine is equipped with a paper pressing groove, which includes an inner paper groove 3111 and an outer carding groove 3112 that are interconnected; and two sets of telescopic cylinders 1011 mounted on the frame 2. A connecting frame 1012 is connected between the bottom ends of the two sets of telescopic cylinders 1011. A top seat 1013 is connected to the middle of the connecting frame 1012. Several push rods 1014 are arranged in a ring on the top of the top seat 1013. The push rods 1014 pass through the annular through holes on the support seat 1016 and correspond one-to-one with the paper pressing groove.

[0023] Furthermore, the frame 2 is also equipped with a turntable 1024 that can rotate intermittently. Several receiving plates 1022 are distributed in a ring on the turntable 1024. Each receiving plate 1022 is equipped with a receiving cylinder 1023. Each receiving cylinder 1023 can correspond to the paper tube 311 in sequence. When the push rod 1014 is pushed up, it is used to receive the paper strip pushed out by the inner paper groove 3111.

[0024] In this embodiment, a feeding paper tube assembly is further provided, such as... Figure 1 , 3 As shown in Figures 4, 6, 11, and 13, the paper pressing groove provided on the outer periphery of the paper tube 311 includes an inner paper groove 3111 and an outer carding groove 3112. The outer carding groove 3112 can be engaged with the ratchet assembly for limiting and locking, and is used to establish a connection with the ratchet assembly. The inner paper groove 3111 is used to place the pressed paper strips. When the cut paper strips are pressed into the inner paper groove 3111 in sequence and fill the entire feeding paper tube assembly, the telescopic cylinder 1011 is activated, which in turn drives the top rod 1014 to move upward, pass through the annular through hole on the support base 1016 in sequence and enter the paper pressing groove, pushing the corresponding paper pressing inside upward and into the corresponding receiving tube 1023.

[0025] Furthermore, the paper conveying assembly includes a paper feed roller assembly 811, a second paper feed seat 812, and a first paper feed seat 314, which are mounted on the frame 2 from bottom to top. The first paper feed seat 314 is fixed to the side wall of the frame 2 by a connecting block 313. The second paper feed seat 812 and the first paper feed seat 314 are staggered. The assembly also includes a second paper feed groove 813 located behind the second paper feed seat 812 and a first paper feed groove 3141 located in front of the first paper feed seat 314. The assembly also includes a paper tray 820, a paper feed detection module 823, and a pre-feed module 821, which are mounted on the frame 2. The paper tray 820 releases the paper belt, which passes through the paper feed detection module 823, the pre-feed module 821, the paper feed roller assembly 811, the second paper feed groove 813, and the first paper feed groove 3141 in sequence, leaving a distance between the pre-feed module 821 and the paper feed roller assembly 811.

[0026] Through further modifications to the paper tape delivery assembly, such as Figure 1 , 4 As shown, the paper strip enters through the feed roller assembly 811. With the help of the second paper feeder 812 and the first paper feeder 314, the paper strip can be advanced on the same plane by being positioned one in front of the other. At the same time, the partition formed by the second paper feeder 812 and the first paper feeder 314 can also provide a cutting position for the cutter assembly. The paper feeding detection module 823 can detect the presence or absence of paper strips. When the paper strips are used up, an alarm can be triggered in time. The pre-feed module 821 always maintains a certain distance between the pre-feed module 821 and the paper feed roller assembly 811. The looseness of the paper strips effectively reduces the possibility of the paper strips being torn in case of emergencies.

[0027] Example 3 In another embodiment of the present invention, the paper pressing assembly includes a first transmission member 512, and a pressing plate 511 is provided at the end of the first transmission member 512 near the paper tube 311. The end of the pressing plate 511 away from the first transmission member 512 passes through the first paper conveying groove 3141 and is connected to the paper pressing groove opened on the paper tube 311. The cutter assembly includes an assembly block 618, on which a slidable second transmission member 612 is mounted. A cutting blade 611 is provided at the front end of the second transmission member 612 and is placed between the second paper conveying seat 812 and the first paper conveying seat 314.

[0028] Furthermore, the cam drive mechanism includes a second transmission wheel 214 and a first transmission wheel 212 rotating in the middle and lower parts of the plate 111, respectively, and a motor 211 fixed on the plate 111 and connected to the first transmission wheel 212. The motor 211 can drive the first transmission wheel 212 to rotate, and a transmission belt 213 meshing between the second transmission wheel 214 and the first transmission wheel 212. The end of the second transmission wheel 214 near the paper pressing assembly passes through a through hole in the plate 111 and is fixed with a drive disk 424, and a cam groove 913 is formed on the drive disk 424; and a second mounting shaft 912 is mounted on the plate 111. A deflectable second rocker arm 914 is mounted around the second mounting shaft 912 as the axis. A limiting post 924 that can move within the cam groove 913 is provided on the second rocker arm 914; and a first bearing 920, a second bearing 921, and a third bearing 920 are sequentially embedded in the plate 111 from top to bottom. 23. A first connecting seat 922 is provided between the first bearing seat 920 and the second bearing seat 921. A first transmission member 512 is slidably mounted on the first connecting seat 922. The end of the first transmission member 512 away from the pressure plate 511 is rotatably mounted with a first transmission rod 513 through a second connecting shaft 514. The end of the first transmission rod 513 away from the second connecting shaft 514 extends into the interior of the second rocker arm 914 and is rotatably connected to the first pin on it. A second connecting seat 925 is assembled between the third bearing seat 923 and the second bearing seat 921. An assembly block 618 is fixed on the second connecting seat 925. A second transmission member 612 is slidably mounted on the second connecting seat 925. The end of the second transmission member 612 away from the cutting blade 611 is rotatably mounted with a second transmission rod 614 through a third connecting shaft 613. The end of the second transmission rod 614 away from the third connecting shaft 613 extends into the interior of the second rocker arm 914 and is rotatably connected to the second pin on it.

[0029] The rotary motion is converted into specific, time-sequential linear or oscillating motion through a cam-driven mechanism, and combined with the paper pressing assembly and the cutter assembly. Specifically, for example... Figure 1 , 2 As shown, when motor 211 operates, under the meshing transmission action of the first transmission wheel 212, transmission belt 213, and second transmission wheel 214, it can drive the drive disc 424 to rotate, in conjunction with... Figure 5 , 7 As shown in Figure 8, when the drive disk 424 rotates, the limiting post 924 can move within the cam groove 913, thereby driving the second swing arm 914 to reciprocate around the second mounting shaft 912. Due to the action of the paper pressing assembly and the cutter assembly at different positions on the second swing arm 914, such as... Figure 8As shown, when the swing end of the second swing arm 914 swings away from the direction of the paper strip, the cutter assembly extends forward and the paper pressing assembly retracts. Conversely, when the swing end of the second swing arm 914 swings close to the direction of the paper strip, the cutter assembly retracts and the paper pressing assembly extends forward, thus achieving a forward and backward orderly action switch.

[0030] Example 4 In another embodiment of the present invention, the ratchet assembly includes a mounting block 414 rotatably mounted on the frame 2, a ratchet 412 mounted on the bottom plate of the mounting block 414, and a limiting strip 4121 disposed inside the ratchet 412. The limiting strip 4121 can be limited and assembled with the outer slot 3112 on the paper tube 311.

[0031] Furthermore, the pawl actuation assembly includes a mounting block 414 fixed on the frame 2, a telescopic strip 415 slidably mounted on the mounting block 414, and a pawl 411 connected to one end of the telescopic strip 415. An elastic pressure strip 413 is fixed to the side wall of the pawl 411 near the telescopic strip 415, for the pawl 411 to tightly abut against the groove of the ratchet 412. The linkage transmission assembly includes a mounting base 429 fixed in the middle of the drive disc 424, a threaded sleeve 427 slidably mounted within the mounting base 429, and an adjusting screw 425 threadedly connected to the threaded sleeve 427. The mounting hole on the mounting base 429 is provided with a rotatable... A rotating handle 426 is fixedly connected to one end of an adjusting screw 425, and a positioning shaft 430 is fixed on a screw sleeve 427. A cam disk 422 is rotatably mounted on the screw sleeve 427 with the positioning shaft 430 as the center. A first mounting shaft 421 is mounted on a plate 111. A deflectable first rocker arm 420 is mounted on a ratchet 412. The protrusion of the cam disk 422 extends into the interior of the first rocker arm 420 and is rotatably connected by a third pin. A connecting rod 423 connects the end of the first rocker arm 420 away from the first mounting shaft 421 and the end of the telescopic bar 415 away from the pawl 411.

[0032] Through further modifications to the pawl actuation component and ratchet disc component, such as Figure 3 , 4 As shown in Figures 5 and 13, after the paper tube 311 is assembled, since the limiting strip 4121 is limited within the outer slot 3112, when the ratchet 412 is moved, it can drive the switching of the paper pressing slot position on the paper tube 311. Specifically, in the structure of the ratchet actuation assembly, the adjusting mechanism composed of the adjusting screw 425 and the screw sleeve 427 can change the relative position of the cam disk 422 relative to the drive disk 424, thereby changing the deflection degree of the first rocker arm 420, and thus controlling the sliding distance of the connecting rod 423 driving the telescopic strip 415, thereby improving the relative position of the ratchet 412 and the mounting block 414 during the overall assembly. Figure 3 , 4As shown, when the swing end of the first swing rod 420 deflects away from the ratchet 412, the connecting rod 423 drives the telescopic strip 415 to move backward. Under the elastic force of the elastic pressure strip 413, the hook part of the pawl 411 is in close contact with the slot where the ratchet 412 is located and drives it to move counterclockwise one notch, thereby enabling the paper tube 311 to move to the next paper pressing slot. When the adjusting screw 425 moves forward, the hook part of the pawl 411 disengages from the slot where the ratchet 412 is located, and the paper tube 311 remains stationary. Thus, during the reciprocating movement of the connecting rod 423, the paper tube 311 can be driven to move counterclockwise. It is worth noting that the adjusting screw 425 drives the screw sleeve 427 to adjust its position, which is used to improve the relative position of the ratchet 412 and the mounting block 414 during overall assembly, such as when changing paper tubes 311 of different specifications.

[0033] Example 5 In another embodiment of the present invention, a slide rail 711 and a fixing member 712 are fixedly mounted on the frame 2. The slide rail 711 is used to slide the plate 111. The fixing member 712 is equipped with a stud 714 and a connecting member 713 that limits the sliding on the stud 714. The connecting member 713 is fixed on the side wall of the plate 111 and a nut 715 that is threadedly connected to the stud 714. When the nut 715 moves spirally, it can be used to move the connecting member 713 horizontally relative to the stud 714.

[0034] In this embodiment, the plate 111 can be finely adjusted relative to the frame 2, such as... Figure 2 , 7 As shown in Figures 9 and 12, since the plate 111 can slide relative to the slide rail 711, when the nut 715 moves spirally relative to the stud 714, it can drive the plate 111 to make a slight adjustment of its horizontal position on the slide rail 711, thereby realizing the adjustment of the assembly position of the plate 111, such as the cutting depth of the cutter assembly and the pressing depth of the paper pressing assembly. In the embodiment 4, the position adjustment of the screw sleeve 427 can also change the relative position of the ratchet 412 and the mounting block 414, so as to work together and adapt.
