Description

Technical Field

[0001] The invention relates to a double-station paper inserting machine, belonging to the technical field of new energy motor processing. Background Art

[0002] At present, the interlayer insulation paper insertion machine is a mechanical device that inserts insulation paper of a certain shape between the layers of the stator core coil. The copper wire coils are evenly arranged along the circumferential direction on the core. Since both copper wire and copper wire are conductors, it is necessary to lay insulators between the copper wire coils to keep them isolated from each other to prevent conductivity.

[0003] In existing machines for inserting insulation paper between motor layers, paper insertion is primarily a manual process. This labor-intensive and fatigue-prone process further impacts paper insertion quality, reduces production efficiency, and increases labor costs. Even with existing paper insertion equipment, paper folding and insertion cannot be integrated, resulting in limited insertion stations and room for improvement in production efficiency.

[0004] In view of the above-mentioned defects, the present invention aims to create a double-station paper inserting machine to make it more valuable in industrial application. Summary of the Invention

[0005] In order to solve the above technical problems, an object of the present invention is to provide a double-station paper inserting machine.

[0006] A double-station paper inserting machine of the present invention comprises a feeding mechanism and a double-station paper inserting mechanism, wherein the double-station paper inserting mechanism is movably mounted on a working mounting frame; the double-station paper inserting mechanism comprises a complete lifting mechanism, wherein the complete lifting mechanism is movably mounted on the working mounting frame, and two station translation mechanisms that can move left and right are symmetrically mounted on the front surface of the complete lifting mechanism; an indentation mechanism and a heating steering mechanism are sequentially arranged above the outer side of the front surface of each station translation mechanism, which are respectively used for indentation processing and heating steering guidance of insulating paper strips. A stepping shaping mechanism and an insulating paper forming mechanism are arranged in sequence from top to bottom below the heating steering mechanism, which are used for stepping and performing preliminary edge shaping and final folding of the insulating paper strips after indentation, respectively. A cutting and folding mechanism is fixedly arranged on one side of the stepping shaping mechanism and the insulating paper forming mechanism, which is used for cutting and folding the insulating paper strips after preliminary shaping by the stepping shaping mechanism. A paper insertion mechanism is also arranged in the vertical direction directly above the insulating paper forming mechanism; it is used to push the folded insulating paper strips downward into the stator to be inserted to complete the paper insertion operation.

[0007] The step-shaping mechanism includes a step-shaping body and a step-transmission motor. The step-shaping body includes a shaping mounting frame fixedly mounted on the surface of the workstation translation mechanism. A step-driving wheel and a step-auxiliary wheel are matched and mounted in the horizontal direction inside the shaping mounting frame. One end of the step-driving wheel is in transmission connection with the output end of the step-transmission motor. The top and bottom ends of the step-shaping body are symmetrically provided with a step-in entrance and a step-outlet, respectively. The step-in entrance and the step-outlet both include a step-channel bottom plate at the bottom, a step-channel pressing plate is provided on the top of the step-channel bottom plate, and a shaping slope is provided at one end of the step-channel pressing plate. The shaping slope faces the step-auxiliary wheel, and the step-active wheel and the step-auxiliary wheel are contacted and connected through the two shaping slopes symmetrically provided on the step-in entrance and the step-outlet, thereby realizing the preliminary extrusion and shaping of the edge of the insulating paper strip. The top of the step-channel pressing plate is fixed by a step-channel cover plate, and a gap is formed between the step-channel pressing plate and the step-channel bottom plate as a step-shaping channel for the insulating paper strip. The stepping driving wheel is a cylindrical structure with raised edge shaping ridges on both sides of its edge, and a concave shaping groove formed between the two edge shaping ridges. The stepping auxiliary wheel is a cylindrical structure that matches the size of the stepping driving wheel, and a center shaping pressure ring and edge grooves that match the shaping groove and edge shaping ridges are provided on the surface of the stepping auxiliary wheel. In actual use, the diverted insulating paper strip enters the stepping shaping channel from the stepping entrance. When passing between the stepping auxiliary wheel and the stepping driving wheel, the creases formed in the previous process of the insulating paper strip are further squeezed by the edge shaping ridge and the shaping groove, so that the edges of the insulating paper strip on both sides are raised to complete the initial shaping, which is convenient for the origami forming in the subsequent steps. Furthermore, the two ends of the stepper wheel are rotatably inserted into the stepper wheel mounting blocks, which are set in the slots on both sides of the shaping mounting frame. The inner side of the stepper wheel mounting block abuts the shaping mounting frame via the stepper tension buffer spring, and the outer side of the stepper wheel mounting block abuts the stepper tension adjuster that is rotatably connected to the shaping mounting frame. The stepper tension adjuster can be used to adjust the tension between the stepper wheel and the stepper active wheel, thereby adjusting the degree of edge shaping. Furthermore, the indentation mechanism includes an indentation wheel mounting frame and an indentation drive motor mounting frame fixed to the surface of the workstation translation mechanism. The indentation drive motor is fixedly mounted on the indentation drive motor mounting frame. The indentation driving wheel and the indentation auxiliary wheel are mounted on the indentation wheel mounting frame from top to bottom. The surfaces of the indentation driving wheel and the indentation auxiliary wheel are respectively provided with indentation grooves and indentation ridges. The surface of the insulating paper strip is indented by squeezing the grooves and ridges. Furthermore, the two ends of the indentation auxiliary wheel are rotatably inserted into the indentation auxiliary wheel mounting seat, and the indentation auxiliary wheel mounting seat is set in the notches on both sides of the indentation wheel mounting frame. The upper end of the indentation auxiliary wheel mounting seat is abutted against the indentation wheel mounting frame through the indentation buffer spring, and the abutment tightness between the indentation auxiliary wheel and the indentation active wheel can be adjusted by the indentation tension adjuster to adjust the depth of the indentation. The lower end of the indentation auxiliary wheel mounting seat is abutted against the indentation tension adjuster rotatably connected to the indentation wheel mounting frame, and one end of the indentation active wheel is connected to the output end of the indentation drive motor. The indentation drive motor drives the indentation active wheel to rotate and drive it to the next workstation while pressing creases on the surface of the insulating paper strip.

[0008] Furthermore, the heating and steering mechanism includes a heater and an arc-shaped steering channel. A plurality of heating resistance wires are provided inside the heater to heat and soften the insulating paper strips entering the heater to facilitate subsequent step-by-step shaping. A heater inlet and a heater outlet are provided at the front and rear ends of the heater respectively. The heater outlet and the inlet of the arc-shaped steering channel are docked. The arc-shaped steering channel includes an arc-shaped steering plate with an arc of 90° and two arc-shaped pressure plates provided on its surface. A gap is provided between the arc-shaped pressure plate and the arc-shaped steering plate to facilitate the passage of the folded insulating paper strips. A gravity pressure wheel is also provided between the two arc-shaped pressure plates to flatten and guide the insulating paper strips passing between the two arc-shaped pressure plates. Each of the arc-shaped pressure plates is provided with an upward-curved pressure plate guide surface at both ends. It is used to guide the entry of the insulating paper strips. In actual operation, the insulating paper strips entering horizontally are guided to be transported vertically downward by the heating and steering mechanism.

The origami transmission disk is rotated to drive the paper inserting board to extend and retract along the paper inserting guide rail, thereby completing the paper folding action.

[0010] Furthermore, the insulating paper forming mechanism is provided with an origami inlet on the side opposite the origami mechanism. The origami inlet is connected to the internal origami insertion cavity channel. The origami inlet is a sloped structure with an outward flaring opening, which facilitates the insertion board to symmetrically press the pre-shaped insulating paper strip into the origami insertion cavity channel to complete the folding of the insulating paper strip. The insertion inlet is provided at the top of the insulating paper forming mechanism, and a forming base is provided at the bottom of the insulating paper forming mechanism. The inner cavity of the forming base is also provided with an origami shaping slope. This is used to guide the final slope shaping of the insulating paper strip during the downward pressing process of the paper insertion mechanism after folding, and finally insert it into the stator to be inserted.

[0011] Furthermore, the paper insertion mechanism includes a paper insertion slide rail and a paper insertion drive disk fixed to the surface of the station translation mechanism in a vertical direction. A paper insertion slider is slidably sleeved on the surface of the paper insertion slide rail. The surface of the paper insertion slider is fixedly connected to a paper insertion push rod mounting seat. The lower end of the paper insertion push rod mounting seat is fixedly connected to a paper insertion push rod in a vertical direction. The paper insertion push rod is directly opposite the paper insertion entrance. The top of the paper insertion push rod mounting seat is hinged to a shaft fixing post at the edge of the paper insertion drive disk surface through a transmission shaft. The back of the paper insertion drive disk is connected to a 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.

[0012] Furthermore, a gravity sensing mechanism is provided between the indentation mechanism and the heating steering mechanism. The gravity sensing mechanism includes a gravity buffer box with an opening at the top. The gravity buffer box is provided with through sensor detection holes near both sides of the bottom. A photoelectric sensor is fixedly provided on one side of the sensor detection hole. The photoelectric sensor and the step shaping mechanism are connected by signal. In actual use, when the insulating paper strip coming out of the indentation mechanism is subjected to the action of its own gravity, it will fall into the gravity buffer box. When the photoelectric sensor detects the drooping insulating paper strip, it will transmit the photoelectric signal to the step shaping mechanism, which will pull the insulating paper strip to the next station through the step shaping mechanism. When the bottom of the pulled insulating paper strip is pulled up beyond the position of the sensor detection hole, the step shaping mechanism stops pulling, so that the subsequent indented insulating paper strip continues to droop by gravity and is cached in the gravity buffer box. Such a cycle facilitates the indentation caching of the insulating paper strip and improves the indentation stability.

[0013] Furthermore, the complete lifting mechanism includes a horizontally arranged lifting mainboard, the back of which is slidably sleeved on the surface of the lifting rail via a lifting rail slider, a plurality of which are evenly fixed to the surface of the working mounting frame in the vertical direction, a lifting motor mounting platform and a screw mounting seat are fixedly arranged in sequence from top to bottom in the vertical direction at the center position of the working mounting frame surface, a lifting motor is installed on the top of the lifting motor mounting platform, a lifting screw is connected to the bottom of the lifting motor in a transmission manner, the bottom of the lifting screw is rotatably inserted into the screw mounting seat, a lifting screw slider is connected to the surface of the lifting screw, and the lifting screw slider is fixedly connected to the back of the lifting mainboard. During actual operation, the lifting mainboard connected to the lifting screw slider is driven by the lifting motor and the lifting screw to move stably up and down along the direction of the lifting rail, thereby facilitating the insertion of paper by aligning the stator to be inserted through up and down displacement.

[0014] Furthermore, the workstation translation mechanism includes a translation mainboard arranged vertically, and a plurality of translation sliders parallel to each other are arranged in the horizontal direction on the back of the translation mainboard.

[0015] Furthermore, the feeding mechanism includes a feeding line and a feeding dividing mechanism arranged in the middle position thereof. Two lifting cylinders are also provided in the middle position of the feeding line to facilitate the feeding tooling flowing in from one end of the feeding line and the stator to be inserted on its surface to be lifted upward and separated from the feeding line, so as to facilitate the subsequent internal support grasping and indexing rotation of the feeding and dividing mechanism; the feeding and dividing mechanism includes a feeding mounting plate fixed to the bottom surface of the middle part of the feeding line, and a feeding lifting mechanism is provided on the side wall of the feeding mounting plate in the vertical direction, and a dividing mounting frame is fixed on the front surface of the feeding lifting mechanism, and a dividing mechanism is installed on the dividing mounting frame.

During actual use, the entire indexing mechanism is first driven by the loading lifting motor to rise into the loading tooling and the stator to be inserted on its surface, and the inner support claws are expanded outward to support the annular inner wall of the stator to be inserted, and the stator to be inserted is continued to be driven to rise to the processing station, so that the double-station paper insertion mechanism can insert the insulating paper into the stator to be inserted. After the two stations insert the insulating paper at the same time, the indexing plate is rotated by a certain angle under the drive of the indexing motor, so that the subsequent double-station paper insertion mechanism can continue to insert the insulating paper. The indexing rotation is cyclic until the stator to be inserted is full of insulating paper.

[0017] Furthermore, the dual-station paper insertion mechanism further 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 backup paper reel symmetrically arranged in a vertical direction.

[0036] The working principle of the present invention is as follows: During the actual use of the double-station paper inserting machine of the present invention, the loading tool 114 equipped with the stator 115 to be inserted is first loaded from one end of the feeding line body 12, and after being transported to the insertion station, the loading tool 114 flowing into the feeding line body 12 and the stator 115 to be inserted on its surface are lifted upward and separated from the feeding line body 12 by two lifting cylinders 113, and the entire indexing mechanism 117 is driven to rise and enter the loading tool 114 and the stator 115 to be inserted on its surface by the loading lifting motor 1121, and the internal support claws are used to hold the loading tool 114 and the stator 115 to be inserted on its surface. 1173 expands outward and supports the inner annular 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 double-station paper insertion mechanism 2 can insert the insulating paper into the stator 115 to be inserted. At the same time, the lifting main board 221 connected to the lifting screw slider 226 is driven by the lifting motor 224 and the lifting screw 225 to move stably up and down along the lifting slide rail 227, so as to facilitate the insertion of paper by aligning the stator 115 to be inserted through the up and down displacement, and the translation motor 234 and the translation screw 235 drive the translation screw slider 226 to move stably up and down along the lifting slide rail 227. The translation main board 231 connected to the block 236 moves stably left and right along the direction of the translation slide rail 237, so as to facilitate the insertion of paper by aligning the stator 115 to be inserted by the left and right displacement. After the alignment is completed, the insulating paper strip 3 guided from the main paper roll 211 is guided into the indentation mechanism 25, and the surface of the insulating paper strip 3 is indented by the indentation groove 2531 and the indentation ridge 2541 on the surface of the indentation driving wheel 253 and the indentation auxiliary wheel 254. It will droop into the gravity buffer box 241. When the photoelectric sensor 243 detects the drooping insulating paper strip 3, it transmits the photoelectric signal to the step-shaping mechanism 27, which pulls the insulating paper strip 3 to the next station through the step-shaping mechanism 27. When the bottom of the pulled insulating paper strip 3 is pulled up beyond the position of the sensor detection hole 242, the step-shaping mechanism 27 stops pulling, allowing the subsequent indented insulating paper strip 3 to continue to droop by gravity and be cached in the gravity buffer box 241. This cycle facilitates the indentation cache of the insulating paper strip 3 and improves the indentation stability. The insulating paper strip 3 entering its interior is then heated and softened by the heating steering mechanism 26 to facilitate subsequent step-shaping. The heating steering mechanism 26 then guides the horizontally entering insulating paper strip 3 to be transported vertically downward.The turned insulating paper strip 3 enters the step shaping channel from the step entrance 272. When passing between the step auxiliary wheel 275 and the step driving wheel 274, the creases formed on the insulating paper strip 3 in the previous process are further squeezed by the edge shaping ridge 2742 and the shaping groove 2741, so that the edges on both sides of the insulating paper strip 3 are raised to complete the preliminary shaping, which is convenient for the paper folding forming in the subsequent steps; then the insulating paper strip 3 shaped by the step shaping mechanism 27 is cut by the cutting mechanism 282; the paper folding transmission disk 2814 is used to rotate and drive the inserting paper board 2831 along the inserting The paper guide rail 2834 is extended and retracted in the direction 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 motor 291 drives the paper insertion push rod 296 to move downward to guide the insulating paper strip to be folded in half and then shaped through the slope, and then inserted into the stator 115 to be inserted. When the two stations insert the insulating paper at the same time, the dividing plate 1172 is rotated by a certain angle under the drive of the dividing motor 1171, so that the subsequent double-station paper insertion mechanism 2 continues to insert the insulating paper. The dividing rotation is cyclical until the stator 115 to be inserted is full of insulating paper.
