Description

Technical Field

[0001] This invention relates to the field of electric motors, specifically to a transverse paper feeding machine for electric motor stator coils. Background Technology

[0002] Stator coils are an essential component of electric motors, playing a crucial role in the entire motor system. Widely used in new energy, robotics, and other fields, stator coils primarily consist of an iron core, insulating paper sleeves, and copper wire windings. The iron core ring has multiple slots. During production, the insulating paper is first folded into insulating paper sleeves, then the insulating paper sleeves are inserted into each slot, and finally, the copper wire windings pass through the insulating paper sleeves.

[0003] like Figure 20 The paper loading process for the iron core shown typically involves first cutting the insulating paper to the appropriate length, then folding the cut insulating paper into insulating sleeves, and finally manually inserting the insulating sleeves into each core slot. Therefore, the existing stator coil paper loading process is inefficient, severely impacting the stator coil production efficiency. Summary of the Invention

[0004] The present invention provides a transverse paper feeding machine for motor stator coils. Its main purpose is to overcome the problem of low paper feeding efficiency caused by the manual paper feeding method used in the existing stator coil cores when feeding the insulating paper sleeve.

[0005] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: A transverse paper feeding machine for motor stator coils includes a frame with a support plate on top. The support plate houses a paper winding reel, a paper guiding structure, a preheating structure, a paper mark rolling structure, a paper feeding structure, a paper cutting and pushing structure, a paper sleeve forming structure, a core fixture structure, and a drive mechanism. The paper winding reel is located on the front right side of the top surface of the support plate, the paper guiding structure is located behind the paper winding reel, the preheating structure, the paper mark rolling structure, the paper feeding structure, and the paper sleeve forming structure are arranged sequentially from right to left, the paper cutting and pushing structure is located in front of the paper sleeve forming structure, the core fixture structure is located above the paper sleeve forming structure, and the drive mechanism is located below the core fixture structure. The paper winding reel is used to wind insulating paper. The insulating paper on the paper winding reel is straightened, preheated, and creased sequentially through a paper-following structure, a preheating structure, and a paper-crease rolling structure. The paper feeding structure delivers the creased insulating paper to one side of the paper sleeve forming structure. The cutting and pushing paper structure cuts the insulating paper and delivers the cut insulating paper into the paper sleeve forming structure. The paper sleeve forming structure is equipped with a liftable push rod. The iron core tooling structure is equipped with multiple upper paper slots that communicate with the interior of the paper sleeve forming structure. The iron core tooling structure is used to install the iron core. The push rod pushes the insulating paper in the paper sleeve forming structure upward to form a paper sleeve, and pushes the formed paper sleeve through the upper paper slots into the core slot of the iron core. The driving mechanism drives the iron core tooling structure to rotate.

[0006] Furthermore, a workbench is provided above the support plate, and the iron core tooling structure and the drive mechanism are located on the workbench. There are two iron core tooling structures, and a connecting part is provided between the two iron core tooling structures.

A third lifting cylinder is provided at the bottom of the base, and the piston rod of the third lifting cylinder is connected to the second lifting block. The side of the fixed block near the pressure roller has multiple guide grooves arranged horizontally in the vertical direction, and each guide groove has a vertical indentation groove.

[0017] As can be seen from the above description of the present invention, compared with the prior art, the present invention has the following advantages: The insulating paper on the paper winding reel is straightened, preheated, and creased by sequentially passing through the paper-straightening structure, the preheating structure, and the paper-crease rolling structure. After completing one crease rolling, the paper-crease rolling structure resets. The paper feeding structure feeds the creased insulating paper to one side of the paper sleeve forming structure. The cutting and pushing paper structure cuts the insulating paper and feeds the cut insulating paper into the paper sleeve forming structure. After the insulating paper enters the paper sleeve forming structure, it undergoes preliminary forming. At the same time, the paper feeding structure resets, followed by the cutting and pushing paper structure resetting. Then, the push rod pushes the preliminarily formed paper sleeve from bottom to top, shaping the paper sleeve into the required shape, and pushes the formed paper sleeve through the upper paper slot into the core slot of the iron core. Finally, the push rod resets, thus completing the paper loading of one core slot. Repeating the above actions can complete the automatic insertion of insulating paper sleeves into all core slots of the iron core, thereby improving the paper loading efficiency of the iron core.

A support plate 2 is provided on the top of the frame 1. The support plate 2 is equipped with a paper winding reel 3, a paper guiding structure 4, a preheating structure 5, a paper mark rolling structure 6, a paper feeding structure 7, a paper cutting and pushing structure 8, a paper sleeve forming structure 9, a core fixture structure 10, and a drive mechanism 11. The paper winding reel 3 is located at the front right of the top surface of the support plate 2. The paper guiding structure 4 is located behind the paper winding reel 3. The preheating structure 5, the paper mark rolling structure 6, the paper feeding structure 7, and the paper sleeve forming structure 9 are arranged sequentially from right to left. The paper cutting and pushing structure 8 is located in front of the paper sleeve forming structure 9. The core fixture structure 10 is located above the paper sleeve forming structure 9, and the drive mechanism 11 is located below the core fixture structure 10. The paper winding disc 3 is used to wind insulating paper. The insulating paper on the paper winding disc 3 is straightened, preheated, and creased by passing through the paper straightening structure 4, the preheating structure 5, and the paper crease rolling structure 6 in sequence. The paper feeding structure 7 feeds the creased insulating paper to one side of the paper sleeve forming structure 9. The cutting and pushing paper structure 8 cuts the insulating paper and feeds the cut insulating paper into the paper sleeve forming structure 9. The paper sleeve forming structure 9 is provided with a liftable push rod 12. The iron core tooling structure 10 is provided with multiple upper paper grooves 100 that communicate with the interior of the paper sleeve forming structure 9. The iron core tooling structure 10 is used to install the iron core 20. The push rod 12 pushes the insulating paper in the paper sleeve forming structure 9 upward to form a paper sleeve, and pushes the formed paper sleeve through the upper paper grooves 100 into the core groove 201 of the iron core 20. The driving mechanism 11 drives the iron core tooling structure 10 to rotate.

[0042] Reference Figure 2 and Figure 7A workbench 21 is provided above the support plate 2. The iron core tooling structure 10 and the drive mechanism 11 are provided on the workbench 21. There are two iron core tooling structures 10, which are arranged one in front of the other. A connecting part 13 is provided between the two iron core tooling structures 10. A rotary cylinder 22 is provided on the workbench 21. The rotary cylinder 22 is connected to the connecting part 13. The drive mechanism 11 is located below one of the iron core tooling structures 10.

[0043] Reference Figures 7 to 11 The two iron core tooling structures 10 are vertically and vertically arranged. Each iron core tooling structure 10 includes a fixed frame 101, a bearing 102, an iron core tooling 103, and a positioning ring 104. The fixed frame 101 is integrally formed and connected to the connecting part 13. The bearing 102 is located inside the fixed frame 101, and the iron core tooling 103 is located inside the bearing 102. The positioning ring 104 is vertically and vertically arranged above the fixed frame 101. The bottom of the positioning ring 104 is provided with three first positioning posts 1041 and three second positioning posts 1042. The top of the fixing frame 101 is provided with three first insertion holes 1011. Each first positioning post 1041 corresponds to one first insertion hole 1011 and can be inserted into the first insertion hole 1011. The iron core fixture 103 is provided with three second insertion holes 1031 that are vertically connected. Each second positioning post 1042 corresponds to one second insertion hole 1031 and can be inserted into the second insertion hole 1031. When the iron core fixture structure 10 located above the drive mechanism 11 descends, its positioning ring 104 is lifted up, causing the first positioning posts 1041 to separate from the first insertion holes 1011, while the second positioning posts 1042 remain in the second insertion holes 1031. The iron core fixture 103 is used to place the iron core 20, and the iron core 20 and the iron core fixture 103 are relatively fixed. Specifically, the iron core fixture 103 is provided with a placement groove 1035 that is adapted to the outer periphery of the iron core 20. The placement groove 1035 is provided with a positioning boss 1036 that is adapted to the inner periphery of the iron core 20. The outer periphery of the positioning boss 1036 is inlaid with three locking parts 1037. When the iron core 20 is placed in the placement groove 1035, the positioning boss 1036 is located on the inner periphery of the iron core 20, and the outer ends of the three locking parts 1037 are locked in the inner periphery 202 of the core groove 201. In this way, the iron core fixture 103 and the iron core 20 are fixed in the circumferential direction.

[0044] Reference Figure 7 , Figure 8 and Figure 10The bottom of the fixing frame 101 is provided with an inwardly extending first support edge 1012, and the bottom of the iron core fixture 103 is provided with an outwardly extending second support edge 1032. The bottom of the bearing 102 is supported between the first support edge 1012 and the second support edge 1032. The top surface of the fixing frame 101 is connected to three first pressure blocks 1013, and the top surface of the iron core fixture 103 is connected to three second pressure blocks 1033. One end of the first pressure block 1013 and one end of the second pressure block 1033 are both pressed against the top surface of the bearing 102. The first pressure block 1013 is provided with a third insertion hole 1014 communicating with the first insertion hole 1011. The first positioning post 1041 can be inserted into the third insertion hole 1014 and the first insertion hole 1011 in sequence. The second pressure block 1033 is provided with a fourth insertion hole 1034 communicating with the second insertion hole 1031. The second positioning post 1042 can be inserted into the fourth insertion hole 1034 and the second insertion hole 1031 in sequence. The first support edge 1012 and the second support edge 1032 support the bearing 102. The first pressure block 1013 and the second pressure block 1033 press the top surface of the bearing 102, so that the bearing 102 is limited in the vertical direction. The iron core fixture 103 can rotate relative to the bearing 102.

[0045] Reference Figure 2 , Figures 7 to 9 The drive mechanism 11 includes an indexing motor 111, a main gear 112, and a driven gear 113. The indexing motor 111 is located at the bottom of the worktable 21, and the main gear 112 and driven gear 113 are located at the top of the worktable 21. The output shaft of the indexing motor 111 is connected to the main gear 112, and the main gear 112 and driven gear 113 mesh. The top of the driven gear 113 is provided with three push rods 114, each push rod 114 corresponding to a second insertion hole 1031 and a second positioning post 1042. When the iron core tooling structure 10 descends, the push rods 114 are inserted into the second insertion holes 1031 and push up the second positioning post 1042, causing the first positioning post 1041 to disengage from the first insertion hole 1011 and the third insertion hole 1014.

[0046] Reference Figure 2 , Figures 7 to 9 A first mounting plate 23 is provided below the workbench 21. The rotary cylinder 22 is connected to the top surface of the first mounting plate 23. The workbench 21 has a mounting opening 24 for placing the rotary cylinder 22. A first lifting cylinder 25 is provided on the top surface of the support plate 2. The piston rod of the first lifting cylinder 25 is connected to the first mounting plate 23. The first lifting cylinder 25 drives the first mounting plate 23, the rotary cylinder 22, and the two iron core tooling structures 10 to rise and fall. In this embodiment, in order to stably drive the first mounting plate 23, the rotary cylinder 22, and the two iron core tooling structures 10 to rise and fall, two first lifting cylinders 25 are symmetrically provided.

[0047] Reference Figure 2 , Figures 7 to 11 , Figure 20 In this invention, two iron core fixture structures 10 are provided to further improve the paper feeding efficiency of the iron core 20. Each iron core fixture 103 of the iron core fixture structure 10 holds an iron core 20, and the iron core 20 is fixed to the iron core fixture 103 after being placed on it. When the first lifting cylinder 25 drives the two iron core tooling structures 10 to rise, the first positioning post 1041 at the bottom of the positioning ring 104 passes through the third insertion hole 1014 and is inserted into the first insertion hole 1011, and the second positioning post 1042 passes through the fourth insertion hole 1034 and is inserted into the second insertion hole 1031. At this time, the positioning ring 104 is restricted by the fixed frame 101, and the iron core tooling 103 is restricted by the positioning ring 104. Therefore, the positioning ring 104 and the iron core tooling 103 cannot rotate. When the rotating cylinder 22 drives the two iron core tooling structures 10 to rotate, the iron core tooling 103 and the iron core 20 will not shift relative to the fixed frame 101 during the rotation process. When the first lifting cylinder 25 drives the two iron core tooling structures 10 to descend, the driven gear 113 is located below one of the iron core tooling structures 10. The push rod 114 on the driven gear 113 is inserted into the corresponding second insertion hole 1031, so that the push rod 114 lifts the second positioning post 1042 of the positioning ring 104 located above the driven gear 113. The positioning ring 104 and the first positioning post 1041 are also lifted. At this time, the first positioning post 1041 is disengaged from the first insertion hole 1011 and the third insertion hole 1014, but the second positioning post 1042 is not disengaged from the second insertion hole 1031. The positioning ring 104 is thus released from its restriction to the fixed frame 101. When the indexing motor 111 drives the driven gear 113 to rotate through the main gear 112, the iron core tooling 103 and the positioning ring 104 also rotate. After one core 20 has finished feeding all the paper, the first lifting cylinder 25 drives the two core tooling structures 10 to rise. At this time, the top rod 114 disengages from the second insertion hole 1031, and the lifted positioning ring 104 falls down, so that the lifted first positioning post 1041 is reinserted into the first insertion hole 1011. Then the rotating cylinder 22 rotates 180° to allow the other core 20 that has not yet been fed paper to feed paper. The core 20 that has finished feeding paper is removed and put back into the core 20 that is waiting to be fed paper.

[0048] Reference Figure 2 , Figure 7 and Figure 20A second mounting plate 14 is provided above the support plate 2, and a first lifting block 15 is provided below the second mounting plate 14. A second lifting cylinder 16 is provided at the top of the second mounting plate 14. The piston rod of the second lifting cylinder 16 is connected to the first lifting block 15. A connecting shaft (not shown in the figure due to view limitations) is provided at the bottom of the first lifting block 15. A rotatable pressure block 17 is provided at the bottom of the connecting shaft (not shown in the figure due to view limitations). The pressure block 17 is located above the iron core tooling structure 10. The second lifting cylinder 16 is used to drive the lifting and lowering of the pressure block 17. When the second lifting cylinder 16 drives the pressure block 17 to descend, the pressure block 17 presses against the inner end top surface of the iron core 20 to prevent the iron core 20 from warping. When the drive mechanism 11 drives the iron core tooling 103 and the iron core 20 to rotate, the pressure block 17 can rotate with it.

[0049] Reference Figure 4 , Figure 12 and Figure 13 The paper-following structure 4 includes a first support column 41, a first roller 42, a second support column 43, and a second roller 44. The first support column 41 and the second support column 43 are both connected to the top surface of the support plate 2. The first roller 42 and the second roller 44 are respectively located at the top of the first support column 41 and the top of the second support column 43. Insulating paper passes between the first roller 42 and the second roller 44. The insulating paper passing between the first roller 42 and the second roller 44 allows the insulating paper to transition during feeding, avoiding uneven feeding due to excessive tilt angle, and also allows the insulating paper to be tensioned. The preheating structure 5 includes a heating block 51 and a first limiting block 52 disposed on one side of the heating block 51. A first paper passage gap 53 is formed between the heating block 51 and the first limiting block 52. The heating block 51 is provided with a mounting hole 54, and a heating tube is disposed in the mounting hole 54. After the heating tube is heated, the heating block 51 can heat and soften the insulating paper to facilitate better subsequent forming and prevent the insulating paper from breaking during forming due to excessive stiffness. In order to make the heating of the insulating paper more uniform, in this embodiment, there are two mounting holes 54, which are arranged vertically.

The pressure roller 63 is located on one side of the fixing block 62. The pressure roller 63 is rotatably connected to the second lifting block 64. A third lifting cylinder 65 is provided at the bottom of the base 61. The piston rod of the third lifting cylinder 65 is connected to the second lifting block 64. The fixing block 62 has four guide grooves 621 arranged horizontally on the side near the pressure roller 63 in the vertical direction. Each guide groove 621 has a vertical indentation groove 622. The fixing block 62 has a transverse paper feed groove 623 on the side near the pressure roller 63. The paper feed groove 623 divides the guide groove 621 into upper and lower parts. The left and right ends of the paper feed groove 623 are connected to second limiting blocks 66. A second paper feed gap 67 is formed between the fixing block 62 and the second limiting blocks 66. The pressure roller 63 has four pressing parts 631 arranged horizontally on the outer periphery. The pressing parts 631 are located in the guide grooves 621. The outer periphery of the pressing parts 631 has pressing teeth 632 that are adapted to the indentation grooves 622. The third lifting cylinder 65 is used to drive the second lifting block 64 and the pressure roller 63 to rise and fall. The pressure roller 63 will roll when it rises and falls. When the pressure roller 63 rolls, the pressing teeth 632 on the four pressing parts 631 cooperate with the indentation groove 622 to roll the softened insulating paper to form creases, so that the insulating paper is easier to bend during subsequent forming.

[0051] Reference Figures 4 to 6 , Figure 15 The paper feeding structure 7 includes a gripper 71 and a first linear slide module 72 that drives the gripper 71 to move left and right. Both grippers of the gripper 71 are connected to clamping blocks 73. The first linear slide module 72 is located on the bottom surface of the support plate 2, and the slide of the first linear slide module 72 is connected to a connecting plate 74. The gripper 71 is connected to the connecting plate 74. The support plate 2 has an opening 26 that provides movement space for the gripper 71. The two grippers of the gripper 71 can open and close. When the two grippers of the gripper 71 are closed, the two clamping blocks 73 on the gripper 71 can clamp the indented insulating paper. Then, the first linear slide module 72 drives the gripper 71 and the insulating paper to move towards the cutting and pushing paper structure 8. After the insulating paper is cut, the first linear slide module 72 and the gripper 71 return to their original positions.

[0052] Reference Figure 4 , Figure 5 , Figure 15 and Figure 16The paper cutting and pushing structure 8 includes a sliding cylinder 81, a mounting block 82, a push block 83, and a cutter 84. The sliding cylinder 81 is located on the top surface of the support plate 2. The mounting block 82 is connected to the sliding table of the sliding cylinder 81. The push block 83 is connected to one side of the mounting block 82. A base plate 85 is connected to the bottom surface of the mounting block 82. The cutter 84 is connected to the top surface of the base plate 85 and is located on one side of the push block 83. The sliding cylinder 81 is used to drive the push block 83 and the cutter 84 to move back and forth. When the paper feeding structure 7 feeds the insulating paper to the required position, the sliding cylinder 81 drives the push block 83 and the cutter 84 to move backward. The cutter 84 cuts the insulating paper, and at the same time, the push block 83 pushes the cut insulating paper into the paper sleeve forming structure 9. After the cutter 84 and the push block 83 complete the cutting and pushing, the sliding cylinder 81 drives the push block 83 and the cutter 84 to move forward and reset.

[0053] Reference Figure 4 , Figure 6 , Figures 16 to 20The paper sleeve forming structure 9 includes a bottom block 91, a support block 92, a first forming block 93, a second forming block 94, a third forming block 95, and a fourth forming block 96 connected sequentially from bottom to top. The bottom block 91 is located on the top surface of the support plate 2. The support block 92 has a vertically penetrating groove 921. The first forming block 93 has a vertically penetrating first forming groove 931. The second forming block 94 has a vertically penetrating second forming groove 941. The third forming block 95 has a vertically penetrating third forming groove 95. 1. The fourth forming block 96 is provided with a fourth forming groove 961 that runs vertically through it. The rod groove 921, the first forming groove 931, the second forming groove 941, the third forming groove 951, and the fourth forming groove 961 are connected in sequence. The diameters of the first forming groove 931, the second forming groove 941, the third forming groove 951, and the fourth forming groove 961 gradually decrease. The push rod 12 can pass through the rod groove 921, the first forming groove 931, the second forming groove 941, the third forming groove 951, and the fourth forming groove 961 in sequence. One side of the first forming block 93 is provided with a paper sleeve inlet 932 that communicates with the first forming groove 931. The bottom surface of the support plate 2 is provided with a second linear slide module 18 that drives the push rod 12 to rise and fall. The slide of the second linear slide module 18 is connected to a connecting block 19. The push rod 12 is connected to the connecting block 19. The support plate 2 is provided with a through hole 27 for the push rod 12 to pass through. The second linear slide module 18 is used to drive the push rod 12 to rise and fall. After the cutter 84 cuts the insulating paper, the push block 83 pushes the cut insulating paper through the paper sleeve inlet 932 to the first forming groove 931 for preliminary forming. Then, the second linear slide module 18 drives the push rod 12 to rise. The push rod 12 pushes the preliminarily formed paper sleeve upward and passes through the second forming groove 941, the third forming groove 951 and the fourth forming groove 961 for gradual forming, finally forming the paper sleeve of the required shape. At the same time, the push rod 12 pushes the formed paper sleeve through the upper paper groove 100 into the core groove 201 of the iron core 20, thereby completing the paper feeding of one paper sleeve. After the paper feeding of one paper sleeve is completed, the second linear slide module 18 drives the push rod 12 to fall back to its original position.

[0054] Reference Figures 2 to 20The working principle of this invention is as follows: The iron core 20 is placed inside the iron core fixture 103 of the iron core fixture structure 10, and the iron core 20 is fixed to the iron core fixture 103 after being placed inside the iron core fixture 103. The first lifting cylinder 25 drives the two iron core fixture structures 10 to descend. The driven gear 113 is located below one of the iron core fixture structures 10. The push rod 114 on the driven gear 113 is inserted into the corresponding second insertion hole 1031, so that the push rod 114 lifts the second positioning post 1042 of the positioning ring 104 located above the driven gear 113. The positioning ring 104 is also lifted. At this time, the first positioning post 1041 is disengaged from the first insertion hole 1011 and the third insertion hole 1014, but the second positioning post 1042 is not disengaged from the second insertion hole 1031. The positioning ring 104 is thus released from the restriction of the fixed frame 101. The insulating paper on the paper winding tray 3 is straightened, preheated, and creased sequentially through the paper straightening structure 4, the preheating structure 5, and the paper crease rolling structure 6. After completing one crease rolling, the paper crease rolling structure 6 resets. The paper feeding structure 7 feeds the creased insulating paper to one side of the paper sleeve forming structure 9. The cutting and pushing paper structure 8 cuts the insulating paper and feeds the cut insulating paper into the paper sleeve forming structure 9. After entering the paper sleeve forming structure 9, the insulating paper undergoes preliminary forming. At the same time, the paper feeding structure 7 resets, followed by the cutting and pushing paper structure 8 resetting. Then, the push rod 12 pushes the preliminarily formed paper sleeve from bottom to top, shaping the paper sleeve into the required shape. The formed paper sleeve is then pushed through the upper paper groove 100 into the core groove 201 of the iron core 20. Finally, the push rod 12 resets, thus completing the feeding of paper into one core groove 201. After each core slot 201 is loaded with paper, the indexing motor 111 drives the driven gear 113 to rotate via the main gear 112. The core fixture 103 and the positioning ring 104 also rotate accordingly, thus enabling the loading of paper into the next core slot 201. Repeating the above actions completes the loading of paper into one core 20. When one core 20 is loaded with paper, the first lifting cylinder 25 drives the two core fixture structures 10 to rise. At this time, the push rod 114 disengages from the second insertion hole 1031, and the lifted positioning ring 104 falls, causing the lifted first positioning post 1041 to re-insert into the first insertion hole 1011. Then, the rotary cylinder 22 rotates 180° to allow another unloaded core 20 to be loaded with paper. The core 20 that has been loaded with paper is removed and replaced with the core 20 to be loaded with paper.

Any non-substantial modifications made to the present invention using this concept shall be considered as infringing upon the protection scope of the present invention.
