Description

Technical Field

[0001] This invention relates to a dual-station paper insertion machine, belonging to the field of new energy motor processing technology. Background Technology

[0002] Currently, the interlayer insulation paper insertion machine is a mechanical device that inserts insulation paper of a certain shape between the layers of stator core coils. The core has uniform copper wire coils along the circumferential direction. Since copper wires are conductors, it is necessary to lay insulators between the copper wire coils to keep them isolated from each other and prevent them from conducting electricity.

[0003] In existing motor interlayer insulation paper insertion machines, the insertion of insulation paper relies primarily on manual operation. Manual paper insertion is physically demanding and prone to fatigue, further impacting insertion quality, resulting in low production efficiency and increased labor costs for employers. Even with paper insertion equipment, it's impossible to integrate folding and insertion, leading to fewer insertion stations and room for improvement in production efficiency.

[0004] In view of the above-mentioned shortcomings, the present invention aims to create a dual-station paper insertion machine, which makes it more industrially valuable. Summary of the Invention

[0005] To solve the above-mentioned technical problems, the purpose of this invention is to provide a dual-station paper insertion machine.

[0006] This invention discloses a dual-station paper insertion machine, comprising a feeding mechanism and a dual-station paper insertion mechanism, wherein the dual-station paper insertion mechanism is movably mounted on a working mounting frame; the dual-station paper insertion mechanism includes an assembly lifting mechanism, which is vertically movable and mounted on the working mounting frame; two station translation mechanisms that can move left and right are symmetrically mounted on the front surface of the assembly lifting mechanism; an indentation mechanism and a heating and deflecting mechanism are sequentially arranged above the outer side of the front surface of each station translation mechanism, respectively used for indenting the insulating paper strips and for heating, deflecting, and guiding them. Below the heating and turning mechanism, from top to bottom, are a stepping shaping mechanism and an insulating paper forming mechanism, which are used for the initial edge shaping and final folding of the embossed insulating paper strips, respectively. A cutting and folding mechanism is fixedly installed on one side of the stepping shaping mechanism and the insulating paper forming mechanism, which is used to cut and fold the insulating paper strips after the initial shaping by the stepping shaping mechanism. Above the insulating paper forming mechanism, a paper insertion mechanism is also installed vertically, which is used to push the folded insulating paper strips downward into the stator to be inserted to complete the paper insertion operation.

[0007] The stepping shaping mechanism includes a stepping shaping body and a stepping drive motor. The stepping shaping body includes a shaping mounting frame fixedly installed on the surface of the station translation mechanism. Inside the shaping mounting frame, a stepping drive wheel and a stepping auxiliary wheel are installed in a matching manner along the horizontal direction. One end of the stepping drive wheel is connected to the output end of the stepping drive motor.

[0008] The stepping shaping body is symmetrically provided with a stepping inlet and a stepping outlet at its top and bottom, respectively. Both the stepping inlet and the stepping outlet include a stepping channel bottom plate located at the bottom. A stepping channel pressure plate is provided on the top of the stepping channel bottom plate. A shaping slope is provided at one end of the stepping channel pressure plate, and the shaping slope faces the stepping auxiliary wheel. The two shaping slopes symmetrically provided on the stepping inlet and the stepping outlet enable the stepping drive wheel and the stepping auxiliary wheel to contact and connect, thereby achieving the initial compression shaping of the edge of the insulating paper strip. The top of the stepping channel pressure plate is covered and fixed by a stepping channel cover plate, forming a gap between the stepping channel pressure plate and the stepping channel bottom plate as a stepping shaping channel for the insulating paper strip.

[0009] The stepping drive wheel has a cylindrical structure with raised edge shaping flanges on both sides of its edge, and a recessed shaping groove is formed between the two edge shaping flanges. The stepping auxiliary wheel has a cylindrical structure that matches the size of the stepping drive wheel, and a central shaping pressure ring and an edge groove that match the shaping groove and edge shaping flanges on its surface. In actual use, the deflected insulating paper strip enters the stepping shaping channel from the stepping inlet. When passing between the stepping auxiliary wheel and the stepping drive wheel, the edge shaping flanges and the shaping groove further compress the creases formed in the previous process of the insulating paper strip, thereby causing the edges of the insulating paper strip to curl up and complete the initial shaping, which facilitates the folding and forming in the subsequent steps.

[0010] Furthermore, the two ends of the stepping auxiliary wheel are rotatably inserted into the stepping auxiliary wheel mounting block, which is set in the slots on both sides of the shaping mounting frame. The inner side of the stepping auxiliary wheel mounting block abuts against the shaping mounting frame through a stepping tension buffer spring, and the outer side of the stepping auxiliary wheel mounting block abuts against a stepping tension adjuster that is rotatably and liftably connected to the shaping mounting frame. The tightness of the abutment between the stepping auxiliary wheel and the stepping drive wheel can be adjusted by the stepping tension adjuster, thereby adjusting the degree of edge shaping.

[0011] Furthermore, the indentation mechanism includes an indentation wheel mounting bracket and an indentation drive motor mounting bracket fixed to the surface of the station translation mechanism. An indentation drive motor is fixedly mounted on the indentation drive motor mounting bracket, and an indentation drive wheel and an indentation auxiliary wheel are fitted together on the indentation wheel mounting bracket from top to bottom. The surfaces of the indentation drive wheel and the indentation auxiliary wheel are respectively provided with matching indentation grooves and indentation protrusions. The surface of the insulating paper strip is indented by the pressure from the grooves and protrusions.

[0012] Furthermore, the two ends of the creasing auxiliary wheel are rotatably inserted into the creasing auxiliary wheel mounting base. The creasing auxiliary wheel mounting base is set in the slots on both sides of the creasing wheel mounting frame. The upper end of the creasing auxiliary wheel mounting base abuts against the creasing wheel mounting frame through a creasing buffer spring. The creasing tension adjustment can be used to adjust the abutment tightness between the creasing auxiliary wheel and the creasing drive wheel, thereby adjusting the creasing depth. The lower end of the creasing auxiliary wheel mounting base abuts against the creasing tension adjustment, which is rotatably and vertically connected to the creasing wheel mounting frame. One end of the creasing drive wheel is connected to the output end of the creasing drive motor. The creasing drive motor drives the creasing drive wheel to rotate, thereby pressing creases onto the surface of the insulating paper strip and simultaneously driving it to move to the next station.

[0013] Furthermore, the heating and steering mechanism includes a heater and an arc-shaped steering channel. The heater contains multiple heating resistance wires to heat and soften the insulating paper strips entering it, facilitating subsequent step-forming. The heater has a heater inlet and an outlet at its front and rear ends, respectively. The heater outlet and the inlet of the arc-shaped steering channel are aligned. The arc-shaped steering channel includes an arc-shaped steering plate with a 90° arc and two arc-shaped pressure plates covering its surface. A gap exists between the arc-shaped pressure plates and the arc-shaped steering plate to allow the folded insulating paper strips to pass through. A gravity pressure roller is also provided between the two arc-shaped pressure plates to flatten and guide the insulating paper strips passing between them. Each arc-shaped pressure plate has upward-curving guide surfaces at both ends to guide the insertion of the insulating paper strips. In actual operation, the heating and steering mechanism guides the horizontally entering insulating paper strips to be conveyed vertically downwards.

[0014] Furthermore, the cutting and folding mechanism includes a cam drive mechanism, and a cutting mechanism and a folding mechanism are coaxially connected at the bottom output end of the cam drive mechanism. The folding mechanism is directly opposite the insulating paper forming mechanism.

[0015] The cam transmission mechanism includes a cam drive motor, the output end of which is connected to a synchronous drive shaft. A cutting drive cam and a folding drive disc are sequentially mounted on the surface of the synchronous drive shaft from top to bottom. The cutting mechanism is connected to the cutting drive cam. The cutting mechanism includes a cutting fixing seat fixedly mounted on the surface of the workstation translation mechanism. A cutter head mounting seat is fixedly connected to the bottom of the cutting fixing seat near the insulating paper forming mechanism. A cutter head guide seat is provided on the bottom surface of the cutter head mounting seat, and a slidable mounting plate is mounted in the cutter head guide seat. The device includes a cutting head positioned directly below the inlet / outlet. A handle rod is fixedly connected to the tail end of the cutting head, and a handle guide rail is provided on the top surface of the handle rod. The handle guide rail is slidably connected to a stabilizing slider mounted on the bottom surface of the cutting base. The cutting head is kept in a stable directional movement by means of the handle guide rail. A handle drive connecting column is provided on the top surface of the end of the handle rod, and the handle drive connecting column is connected to a cutting drive cam. The cutting head is driven to move forward and backward by the rotation of the cutting drive cam, thus completing the cutting action.

[0016] The folding mechanism includes a paper insertion guide rail fixedly mounted on the surface of the station translation mechanism. A paper insertion board mounting base is slidably fitted onto the surface of the paper insertion guide rail via a folding slider. A plate-like paper insertion board is vertically arranged on the paper insertion board mounting base. A paper insertion drive shaft is hinged to the tail end of the paper insertion drive shaft, and the tail end of the paper insertion drive shaft is hinged to the bottom edge of the folding drive disc via a paper insertion drive shaft connecting column. The folding drive disc rotates, driving the paper insertion board to extend and retract along the direction of the paper insertion guide rail, thereby completing the folding action.

[0017] Furthermore, the insulating paper forming mechanism has a folding inlet on the side opposite the folding mechanism. This folding inlet communicates with the internal folding insertion cavity channel. The folding inlet has an outwardly flared sloping structure, facilitating the insertion board to symmetrically press the pre-shaped insulating paper strip into the folding insertion cavity channel to complete the folding of the insulating paper strip. An insertion inlet is located at the top of the insulating paper forming mechanism, and a forming base is located at the bottom. A folding shaping slope is also provided within the forming base cavity. This slope is used for the final sloping guidance and shaping of the insulating paper strip during the pressing process of the insertion mechanism after folding, and finally for insertion into the stator to be inserted.

[0018] Furthermore, the paper insertion mechanism includes a paper insertion slide rail and a paper insertion drive disk fixed vertically to the surface of the station translation mechanism. A paper insertion slider is slidably sleeved on the surface of the paper insertion slide rail. A paper insertion push rod mounting seat is fixedly connected to the surface of the paper insertion slider. A paper insertion push rod is fixedly connected to the lower end of the paper insertion push rod mounting seat vertically. The paper insertion push rod faces the paper insertion inlet. The top end of the paper insertion push rod mounting seat is hinged to a shaft fixing post at the edge of the paper insertion drive disk via a transmission shaft. The back of the paper insertion drive disk is connected to the paper insertion motor. In actual use, the paper insertion motor drives the paper insertion push rod to move up and down to complete the paper pushing action.

[0019] Furthermore, a gravity sensing mechanism is provided between the indentation mechanism and the heating and steering mechanism. This gravity sensing mechanism includes a gravity buffer box with an open top. The gravity buffer box has through-hole sensor detection holes on both sides near the bottom. A photoelectric sensor is fixedly installed on one side of each sensor detection hole, and the photoelectric sensor is signal-connected to the stepping shaping mechanism. In actual use, the insulating paper strip exiting the indentation mechanism will hang down into the gravity buffer box due to its own weight. When the photoelectric sensor detects the hanging insulating paper strip, it transmits a photoelectric signal to the stepping shaping mechanism. The stepping shaping mechanism then pulls the insulating paper strip to the next station. When the bottom of the pulled insulating paper strip is pulled up beyond the position of the sensor detection hole, the stepping shaping mechanism stops pulling, allowing subsequent indented insulating paper strips to continue hanging down under gravity and being buffered in the gravity buffer box. This cycle facilitates the buffering of the insulating paper strips during indentation, improving indentation stability.

[0020] Furthermore, the assembly lifting mechanism includes a horizontally arranged lifting main board. The back of the lifting main board is slidably fitted onto the surface of the lifting slide rail via a lifting slide rail slider. Multiple lifting slide rails are evenly fixed vertically to the surface of the work mounting frame. At the center of the work mounting frame surface, a lifting motor mounting platform and a lead screw mounting seat are sequentially fixed vertically from top to bottom. A lifting motor is mounted on the top of the lifting motor mounting platform, and a lifting lead screw is driven to the bottom of the lifting motor. The bottom of the lifting lead screw is rotatably inserted into the lead screw mounting seat. A lifting lead screw slider is driven to the surface of the lifting lead screw, and the lifting lead screw slider is fixedly connected to the back of the lifting main board. In actual operation, the lifting motor and lifting lead screw drive the lifting main board connected to the lifting lead screw slider to move stably up and down along the lifting slide rail, thus facilitating alignment of the paper with the stator to be inserted through vertical displacement.

[0021] Furthermore, the workstation translation mechanism includes a vertically arranged translation main board. Multiple parallel translation sliders are arranged horizontally on the back of the translation main board. The translation sliders are slidably sleeved on a translation rail surface fixedly arranged on the front surface of the lifting main board. A translation screw fixing seat and a translation motor mounting seat are arranged sequentially from the inside to the outside along the horizontal direction on the front surface of the lifting main board. A translation motor is fixedly connected to the outer end of the translation motor mounting seat. A translation screw is driven to the output end of the translation motor. The end of the translation screw is rotatably inserted into the translation screw fixing seat. The translation screw is also driven to a translation screw slider, which is fixedly connected to the back of the translation main board.

[0022] Furthermore, the feeding mechanism includes a feeding line and a feeding indexing mechanism located in its middle position. Two lifting cylinders are also provided in the middle position of the feeding line to facilitate the upward lifting of the feeding fixture and the stator to be inserted on its surface from one end of the feeding line, so as to facilitate the subsequent internal support gripping and indexing rotation of the feeding indexing mechanism. The feeding indexing mechanism includes a feeding mounting plate fixed to the bottom surface of the middle part of the feeding line. A feeding lifting mechanism is provided in the vertical direction on the side wall of the feeding mounting plate. An indexing mounting frame is fixedly provided on the front surface of the feeding lifting mechanism, and an indexing mechanism is installed on the indexing mounting frame.

[0023] Furthermore, the feeding lifting mechanism includes a feeding lifting motor located at the top of the feeding mounting plate. The bottom output end of the feeding lifting motor is drivenly connected to a feeding lifting screw. A feeding lifting slider is drivenly sleeved on the surface of the feeding lifting screw. Two feeding lifting slide rails are symmetrically arranged on both sides of the feeding lifting screw in the vertical direction. The feeding lifting slider is fixedly connected to the indexing mounting frame. The back of the indexing mounting frame is also slidably sleeved with the feeding lifting slide rails through a sliding sleeve. The indexing mechanism includes an indexing motor installed at the bottom of the indexing mounting frame. The top output end of the indexing motor is drivenly connected to an indexing plate. An inner support gripper is also provided on the top surface of the indexing plate. In actual use, the entire indexing mechanism is first raised by the feeding lifting motor and enters the feeding fixture and the stator to be inserted on its surface. The inner support claws expand outward and support the inner wall of the stator to be inserted, and continue to raise the stator to the processing station, so that the dual-station paper insertion mechanism can insert insulating paper into the stator. When the insulating paper is inserted at both stations at the same time, the indexing plate rotates at a certain angle under the drive of the indexing motor, so that the subsequent dual-station paper insertion mechanism can continue to insert insulating paper. This cycle of indexing and rotation continues until the stator is full of insulating paper.

[0024] Furthermore, the dual-station paper insertion mechanism also includes a paper winding mechanism symmetrically arranged on both sides of the station translation mechanism. The paper winding mechanism includes a main paper reel and a spare paper reel symmetrically arranged vertically. An insulating paper guiding mechanism is also provided between the main paper reel and the spare paper reel. This mechanism guides the insulating paper strips exiting from the main paper reel into the creasing mechanism.

[0025] By means of the above-described solution, the present invention has at least the following advantages:

[0026] The dual-station paper insertion machine of this invention integrates feeding, folding, and insertion. The dual-station paper insertion design enables rapid production, greatly reduces the labor intensity of workers, saves manpower, and produces high-quality products.

[0075] The specific embodiments of the present invention will be described in further detail below with reference to the accompanying drawings and examples. The following examples are for illustrative purposes only and are not intended to limit the scope of the invention.

Two station translation mechanisms 23 that can move left and right are symmetrically mounted on the front surface of the whole-unit lifting mechanism 22.

[0078] See Figure 3 Each of the workstation translation mechanisms 23 has an indentation mechanism 25 and a heating and turning mechanism 26 arranged sequentially on the upper outer side of its front surface. These are used for indentation of the insulating paper strip 3 and heating and turning of the paper strip 3, respectively. Below the heating and turning mechanism 26, a stepping shaping mechanism 27 and an insulating paper forming mechanism 30 are arranged sequentially from top to bottom. These are used for the initial edge shaping and final folding of the indented insulating paper strip 3, respectively. A cutting and folding mechanism 28 is fixedly arranged on one side of the stepping shaping mechanism 27 and the insulating paper forming mechanism 30. This mechanism is used for cutting and folding the insulating paper strip 3 after the initial shaping by the stepping shaping mechanism 27. Above the insulating paper forming mechanism 30, a paper insertion mechanism 29 is arranged vertically. This mechanism is used to push the folded insulating paper strip 3 downward into the stator 115 to complete the paper insertion operation.

[0079] See Figure 4 and Figure 5 The assembly lifting mechanism 22 includes a horizontally arranged lifting main plate 221. The back of the lifting main plate 221 is slidably sleeved onto the surface of the lifting slide rail 227 via a lifting slide rail slider 228. Multiple lifting slide rails 227 are provided and evenly fixed vertically to the surface of the working mounting frame 4. A lifting motor mounting platform 222 and a lead screw mounting seat 223 are sequentially fixed vertically from top to bottom at the center of the working mounting frame 4.

In actual operation, the lifting motor 224 and the lifting screw 225 drive the lifting main board 221 connected to the lifting screw slider 226 to move stably up and down along the lifting slide rail 227, which facilitates the alignment of the paper with the stator 115 to be inserted by vertical displacement.

[0080] The station translation mechanism 23 includes a vertically arranged translation main board 231. Multiple parallel translation sliders 238 are arranged horizontally on the back of the translation main board 231. The translation sliders 238 are slidably sleeved on the surface of a translation rail 237 fixedly arranged on the front surface of the lifting main board 221. A translation screw fixing seat 233 and a translation motor mounting seat 232 are arranged sequentially from the inside to the outside on the front surface of the lifting main board 221. A translation motor 234 is fixedly connected to the outer end of the translation motor mounting seat 232. A translation screw 235 is drivenly connected to the output end of the translation motor 234. The end of the translation screw 235 is rotatably inserted into the translation screw fixing seat 233. A translation screw slider 236 is also drivenly sleeved on the translation screw 235. The translation screw slider 236 is fixedly connected to the back of the translation main board 231. In actual use, the translation motor 234 and the translation screw 235 drive the translation main board 231 connected to the translation screw slider 236 to move stably left and right along the translation slide rail 237, which facilitates the alignment of the paper with the stator 115 to be inserted by left and right displacement.

[0081] See Figures 6 to 8 The feeding mechanism 1 includes a feeding line 12 and a feeding indexing mechanism 11 located in its middle position. Two lifting cylinders 113 are also provided in the middle position of the feeding line 12 to facilitate the upward lifting of the feeding fixture 114 flowing in from one end of the feeding line 12 and the stator 115 to be inserted on its surface, so as to facilitate the subsequent internal support gripping of the feeding indexing mechanism 11 for indexing and rotation. The feeding indexing mechanism 11 includes a feeding mounting plate 111 fixed to the bottom surface of the middle part of the feeding line 12. A feeding lifting mechanism 112 is provided in the vertical direction on the side wall of the feeding mounting plate 111. An indexing mounting frame 116 is fixedly provided on the front surface of the feeding lifting mechanism 112, and an indexing mechanism 117 is installed on the indexing mounting frame 116.

[0082] The feeding lifting mechanism 112 includes a feeding lifting motor 1121 located at the top of the feeding mounting plate 111. The bottom output end of the feeding lifting motor 1121 is connected to a feeding lifting screw 1122. A feeding lifting slider 1123 is sleeved on the surface of the feeding lifting screw 1122. Two feeding lifting slide rails 1124 are symmetrically arranged on both sides of the feeding lifting screw 1122 in the vertical direction. The feeding lifting slider 1123 is fixedly connected to the indexing mounting frame 116. The back of the indexing mounting frame 116 is slidably sleeved with the feeding lifting slide rails 1124 through a sliding sleeve. The indexing mechanism 117 includes an indexing motor 1171 installed at the bottom of the indexing mounting frame 116. The top output end of the indexing motor 1171 is connected to an indexing plate 1172. An inner support gripper 1173 is also provided on the top surface of the indexing plate 1172. In actual use, the feeding lifting motor 1121 first drives the entire indexing mechanism 117 to rise into the feeding fixture 114 and the stator 115 to be inserted on its surface. The inner support claw 1173 expands outward and supports the inner ring wall of the stator 115 to be inserted, and continues to drive the stator 115 to be inserted to the processing station, so that the dual-station paper insertion mechanism 2 can insert insulating paper into the stator 115. When the insulating paper is inserted at both stations at the same time, the indexing plate 1172 rotates at a certain angle under the drive of the indexing motor 1171, so that the dual-station paper insertion mechanism 2 can continue to insert insulating paper. This cycle of indexing and rotation continues until the stator 115 is filled with insulating paper.

[0083] See Figure 9 The dual-station paper insertion mechanism 2 also includes a paper winding mechanism 21 symmetrically arranged on both sides of the station translation mechanism 23. The paper winding mechanism 21 includes a main paper winding reel 211 and a spare paper winding reel 212 symmetrically arranged vertically. An insulating paper guiding mechanism 213 is also provided between the main paper winding reel 211 and the spare paper winding reel 212 to guide the insulating paper strip 3 exported from the main paper winding reel 211 into the indentation mechanism 25.

[0084] See Figure 10 The indentation mechanism 25 includes an indentation wheel mounting bracket 251 and an indentation drive motor mounting bracket 252 fixed on the surface of the station translation mechanism 23.

The abutment tightness between the embossing auxiliary wheel 254 and the embossing drive wheel 253 can be adjusted by adjusting the embossing tension adjuster 2521, thereby adjusting the depth of the embossing. One end of the embossing drive wheel 253 is connected to the output end of the embossing drive motor 255. The embossing drive motor 255 drives the embossing drive wheel 253 to rotate, thereby pressing creases into the surface of the insulating paper strip 3 and driving it to move to the next station.

[0086] See Figure 11 A gravity sensing mechanism 24 is also provided between the indentation mechanism 25 and the heating and steering mechanism 26. The gravity sensing mechanism 24 includes a gravity buffer box 241 with an opening at the top. The gravity buffer box 241 has through sensor detection holes 242 on both sides near the bottom. A photoelectric sensor 243 is fixedly installed on one side of the sensor detection hole 242. The photoelectric sensor 243 is connected to the stepping shaping mechanism 27. In actual use, when the insulating paper strip 3 coming out of the indentation mechanism 25 is subjected to its own gravity, it will... The insulating paper strip 3 is lowered into the gravity buffer box 241. When the photoelectric sensor 243 detects the lowered insulating paper strip 3, it transmits the photoelectric signal to the stepping shaping mechanism 27. The stepping shaping mechanism 27 pulls the insulating paper strip 3 to the next station. When the bottom of the pulled insulating paper strip 3 is pulled up beyond the position of the sensor detection hole 242, the stepping shaping mechanism 27 stops pulling, so that the subsequent indented insulating paper strip 3 continues to hang down under gravity and is buffered in the gravity buffer box 241. This cycle facilitates the indentation buffering of the insulating paper strip 3 and improves the indentation stability.

[0087] See Figure 12 and Figure 13The heating and steering mechanism 26 includes a heater 261 and an arc-shaped steering channel 263. The heater 261 has multiple heating resistance wires 2612 inside, used to heat and soften the insulating paper strips 3 entering it, facilitating subsequent step-by-step shaping. The heater 261 has a heater inlet 2611 and a heater outlet 2613 at its front and rear ends, respectively. The heater outlet 2613 is connected to the inlet of the arc-shaped steering channel 263. The arc-shaped steering channel 263 includes an arc-shaped steering plate 2631 with a 90° arc and two arc-shaped... The pressure plate 2632 has a gap between the arc-shaped pressure plate 2632 and the arc-shaped turning plate 2631 to facilitate the passage of the folded insulating paper strip 3. A gravity pressure roller 262 is also provided between the two arc-shaped pressure plates 2632 to flatten and guide the insulating paper strip 3 passing between the two arc-shaped pressure plates 2632. Each arc-shaped pressure plate 2632 has an upward-curved pressure plate guide surface 26321 at both ends to guide the passage of the insulating paper strip 3. In actual operation, the horizontally entering insulating paper strip 3 is guided to be vertically conveyed downward by the heating turning mechanism 26.

[0088] See Figures 14 to 17 The stepping shaping mechanism 27 includes a stepping shaping body 271 and a stepping drive motor 2711.

[0089] The two ends of the stepping auxiliary wheel 275 are rotatably inserted into the stepping auxiliary wheel mounting block 276. The stepping auxiliary wheel mounting block 276 is set in the slots on both sides of the shaping mounting frame 2712. The inner side of the stepping auxiliary wheel mounting block 276 abuts against the shaping mounting frame 2712 through the stepping tension buffer spring 278. The outer side of the stepping auxiliary wheel mounting block 276 abuts against the stepping tension adjuster 277, which is rotatably and liftably connected to the shaping mounting frame 2712. The abutment tightness between the stepping auxiliary wheel 275 and the stepping drive wheel 274 can be adjusted by adjusting the stepping tension adjuster 277, thereby adjusting the degree of edge shaping. The top and bottom of the stepping shaping body 271 are symmetrically provided with stepping inlet 272 and stepping outlet 273, respectively. The stepping inlet 272... Both the inlet and outlet 273 include a stepping channel base plate 2721 at the bottom. A stepping channel pressure plate 2722 is provided on the top of the stepping channel base plate 2721. One end of the stepping channel pressure plate 2722 is provided with a shaping slope 27221. The shaping slope 27221 faces the stepping auxiliary wheel 275. The two shaping slopes 27221 symmetrically arranged on the stepping inlet 272 and the stepping outlet 273 make the stepping drive wheel 274 and the stepping auxiliary wheel 275 contact and connect, realizing the initial compression and shaping of the edge of the insulating paper strip 3. The top of the stepping channel pressure plate 2722 is covered and fixed by the stepping channel cover plate 2723, forming a gap between the stepping channel pressure plate 2722 and the stepping channel base plate 2721 as a stepping shaping channel for the insulating paper strip 3.

[0090] The stepper drive wheel 274 has a cylindrical structure with raised edge shaping flanges 2742 on both sides of its edge, and a recessed shaping groove 2741 is formed between the two edge shaping flanges 2742. The stepper auxiliary wheel 275 has a cylindrical structure that matches the size of the stepper drive wheel 274.

[0091] In actual use, the deflected insulating paper strip 3 enters the stepping shaping channel from the stepping inlet 272. When passing between the stepping auxiliary wheel 275 and the stepping drive wheel 274, the creases formed in the previous process of the insulating paper strip 3 are further squeezed through the edge shaping protrusion 2742 and the shaping groove 2741, so that the edges of the insulating paper strip 3 on both sides are raised to complete the initial shaping, which is convenient for the folding and forming in the subsequent steps.

[0092] See Figures 18 to 21 The cutting and folding mechanism 28 includes a cam transmission mechanism 281. A cutting mechanism 282 and a folding mechanism 283 are coaxially connected at the bottom output end of the cam transmission mechanism 281. The folding mechanism 283 is directly opposite the insulating paper forming mechanism 30.

[0093] The cam transmission mechanism 281 includes a cam transmission motor 2811, and the output end of the cam transmission motor 2811 is connected to a transmission synchronous shaft 2812.

The tail end of the 827 is fixedly connected to a handle 2825. The top surface of the handle 2825 is provided with a handle guide slide rail 2826. The handle guide slide rail 2826 is slidably connected to a stabilizing slider 2824 installed on the bottom surface of the cutting base 2821. The handle guide slide rail 2826 is used to maintain the stable directional movement of the cutting head 2827. The top surface of the end of the handle 2825 is provided with a handle transmission connecting column 2828. The handle transmission connecting column 2828 is connected to the cutting transmission cam 2813. The rotation of the cutting transmission cam 2813 drives the cutting head 2827 to move forward and backward to complete the cutting action.

[0095] The folding mechanism 283 includes a paper insertion guide rail 2834 fixedly installed on the surface of the station translation mechanism 23. A paper insertion board mounting base 2832 is slidably sleeved on the surface of the paper insertion guide rail 2834 via a folding slider 2833. A plate-shaped paper insertion board 2831 is vertically arranged on the paper insertion board mounting base 2832. A paper insertion drive shaft 2835 is hinged to the tail end of the paper insertion drive shaft 2832. The tail end of the paper insertion drive shaft 2835 is hinged between the paper insertion drive shaft connecting column 2836 and the bottom edge of the folding drive disk 2814. The folding drive disk 2814 rotates to drive the paper insertion board 2831 to extend and retract along the direction of the paper insertion guide rail 2834, thereby completing the folding action.

[0096] See Figure 22The insulating paper forming mechanism 30 has a folding inlet 32 ​​on the side opposite to the folding mechanism 283. The folding inlet 32 ​​is connected to the internal folding insertion cavity channel 301. The folding inlet 32 ​​is a sloping structure that expands outward, which facilitates the insertion board 2831 to symmetrically press the pre-shaped insulating paper strip 3 into the folding insertion cavity channel 301 to complete the folding of the insulating paper strip 3. The insulating paper forming mechanism 30 has an insertion inlet 33 at the top for the insertion mechanism 29 to insert and perform the insertion action. The insulating paper forming mechanism 30 has a forming base 31 at the bottom. The forming base 31 also has a folding shaping slope 311 in its inner cavity, which is used to guide the insulating paper strip 3 to the final slope shape during the pressing process of the insertion mechanism 29 after folding, and finally insert it into the stator 115 to be inserted.

[0097] See Figure 23 The paper insertion mechanism 29 includes a paper insertion slide rail 297 and a paper insertion drive disk 292 fixed vertically to the surface of the station translation mechanism 23.

The top end of the paper insertion push rod mounting seat 295 is hinged to the shaft fixing post 293 at the edge of the surface of the paper insertion drive disk 292 through a transmission shaft 294. The back of the paper insertion drive disk 292 is connected to the paper insertion motor 291. In actual use, the paper insertion push rod 296 is driven up and down by the paper insertion motor 291 to complete the paper pushing action.

[0098] The working principle of this invention is as follows:

[0099] In actual use, the dual-station paper insertion machine of the present invention first feeds the loading fixture 114, which contains the stator 115 to be inserted, from one end of the feeding line 12. After being transported to the insertion station, the loading fixture 114 and the stator 115 to be inserted on its surface are lifted upwards and detached from the feeding line 12 by two lifting cylinders 113. The loading lifting motor 1121 drives the entire indexing mechanism 117 to rise and enter the loading fixture 114 and the stator 115 to be inserted on its surface, and the internal support claws... 1173 expands outward and supports the inner ring of the stator 115 to be inserted, continuing to lift the stator 115 to the processing station, facilitating the insertion of insulating paper into the stator 115 by the dual-station paper insertion mechanism 2. Simultaneously, the lifting main plate 221, connected to the lifting screw slider 226 via the lifting motor 224 and lifting screw 225, moves stably up and down along the lifting rail 227, facilitating alignment of the paper with the stator 115 during insertion via vertical displacement. The translation motor 234 and translation screw 235 then drive the translation screw slider... The translation main board 231 connected to block 236 moves stably left and right along the translation slide rail 237, which facilitates alignment with the stator 115 to be inserted during paper insertion. After alignment, the insulating paper strip 3 led out from the main paper roll 211 is guided into the creasing mechanism 25. The surface of the insulating paper strip 3 is creasing by the creasing grooves 2531 and creasing protrusions 2541 on the surface of the creasing drive wheel 253 and the creasing auxiliary wheel 254. When the insulating paper strip 3 comes out of the creasing mechanism 25, it is creasing due to its own weight. The insulating paper strip 3 will hang down into the gravity buffer box 241. When the photoelectric sensor 243 detects the hanging insulating paper strip 3, it transmits a photoelectric signal to the stepping shaping mechanism 27. The stepping shaping mechanism 27 pulls the insulating paper strip 3 to the next station. When the bottom of the pulled insulating paper strip 3 is pulled up beyond the position of the sensor detection hole 242, the stepping shaping mechanism 27 stops pulling, so that the subsequent indented insulating paper strip 3 continues to hang down under gravity and be buffered in the gravity buffer box 241. This cycle facilitates the indentation buffering of the insulating paper strip 3 and improves the indentation stability. Then, the heating and turning mechanism 26 heats and softens the insulating paper strip 3 that has entered into the box, making it easier for subsequent stepping shaping. The heating and turning mechanism 26 then guides the horizontally entering insulating paper strip 3 to be conveyed vertically downward.The deflected insulating paper strip 3 enters the stepping shaping channel from the stepping inlet 272. As it passes between the stepping auxiliary wheel 275 and the stepping drive wheel 274, the edge shaping protrusion 2742 and shaping groove 2741 further compress the creases formed in the previous process, causing the edges of the insulating paper strip 3 to curl up and complete the initial shaping, facilitating folding in subsequent steps. Then, the cutting mechanism 282 cuts the insulating paper strip 3 shaped by the stepping shaping mechanism 27. Finally, the folding transmission disc 2814 rotates and drives the insertion plate 2831 along the insertion... The paper guide rail 2834 extends and retracts in the direction of the paper to fold the shaped and cut insulating paper strip 3 into the insulating paper forming mechanism 30 to complete the paper folding action. Finally, the paper insertion push rod 296 is driven by the paper insertion motor 291 to move downward to guide the insulating paper strip after folding it in half through the slope and insert it into the stator 115 to be inserted. When the insulating paper is inserted at both stations at the same time, the indexing plate 1172 rotates at a certain angle under the drive of the indexing motor 1171 to facilitate the subsequent insertion of insulating paper by the dual-station paper insertion mechanism 2. This cycle of indexing and rotation continues until the stator 115 to be inserted is filled with insulating paper.

[0100] The above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of the present invention, and these improvements and modifications should also be considered within the scope of protection of the present invention.
