Description

Technical Field

[0001] This invention belongs to the field of rotor inserting machine technology, specifically relating to an inserting mechanism and inserting method for a motor rotor inserting machine. Background Technology

[0002] Servo motors are a type of motor widely used in applications requiring precise control of position, speed, and torque. They are not only core actuators in modern automated equipment but are also increasingly found in high-end home appliances, robots, and medical equipment. The motor rotor is one of the core components of a servo motor, responsible for rotating under the influence of a magnetic field, thereby converting electrical energy into mechanical energy or vice versa. During the manufacturing process of a servo motor rotor, insulating sheets typically need to be inserted, requiring an inserting machine. However, existing methods for inserting these sheets into motor rotors present the following problems:

[0003] 1. When inserting insulating sheets into the motor rotor, multiple steps need to be performed sequentially, including cutting the insulating sheets, pressing down the insulating sheets, aligning and inserting the insulating sheets, and rotating the motor rotor with gaps. Existing cutting equipment does not connect these steps and requires separate control, which is cumbersome and increases equipment costs. For example, Chinese patent application number CN213937701U, which is an automatic inserting machine for insulating paper into motor rotors, is cumbersome to operate and has low work efficiency.

[0004] 2. Before the motor rotor is fitted with the insulating sheets, the previous production steps may leave dust and debris in the motor rotor slots. Direct insertion will affect the insertion of the insulating sheets, causing wrinkles in the insulating sheets and making it difficult to insert them in one go, thus reducing the insertion efficiency. Summary of the Invention

[0005] The purpose of this invention is to provide a simple and rationally designed inserting mechanism and inserting method for a motor rotor inserting machine in order to solve the above-mentioned problems.

[0019] A method for inserting rotor laminations into an electric motor includes the following steps:

[0020] S1. Rotor loading: First, the motor rotor is transported from front to back using a conveyor. When the conveyor stops at the middle, the motor rotor is lifted using a lifting assembly until the top of the motor rotor is in contact with the bottom of the cover, thus completing the loading of the motor rotor.

[0021] S2. Insulation tape slitting: After the motor rotor is loaded, the automatic feeder will convey the insulation tape along the guide groove. After the loading is completed, the insulation tape will be cut into fixed lengths by the slitting component under the drive of the transmission component.

[0022] S3. Air cleaning: During the cutting process described above, the air cleaning component is simultaneously driven to clean the slots of the motor rotor by blowing air to remove impurities and debris from the slots.

[0023] S4. Aligning the insert: After the air cleaning is completed, the transmission component drives the pressing component to press down and press the cut insulating sheet into the limiting groove. Then, under the push of the insertion plate, the insulating sheet is inserted into the motor rotor slot, thus realizing the insert installation.

[0024] S5. Material unloading and conveying: After installation, the lifting assembly lowers the installed motor rotor into the conveyor, which then transports it to the next process step.

[0025] The beneficial effects of this invention are as follows:

[0026] 1. Unlike existing technologies, this invention achieves multiple steps such as insulating sheet cutting, insulating sheet pressing, and alignment insertion through the coordinated use of transmission components, cutting components, and pressing components, thereby improving the automation level of the equipment and increasing production efficiency.

[0027] 2. Unlike existing technologies, this invention uses the pressing component and the air blowing dust removal component in combination. During the pressing process of the pressing component pressing down the insulating sheet, the air blowing dust removal component is driven to work simultaneously, realizing the air blowing cleaning of the motor rotor slot. This facilitates the removal of dust and impurities from the slot, avoids the situation where impurities block the insertion of the insulating sheet, and ensures the smooth insertion of the insulating sheet.

[0028] 3. Unlike existing technologies, the supporting unlocking component provides bottom support for the insulating sheet, providing bottom support force during cutting to ensure the cleanliness of the cut surface and reduce tearing during cutting. The supporting unlocking component is also telescopic; after cutting, the supporting plate automatically retracts as the pressing component depresses, avoiding interference with the pressing process. Furthermore, the pressing component presses the cut insulating sheet into the limiting groove, ensuring accurate alignment with the motor rotor slot and facilitating accurate insertion of the insulating sheet.

[0029] 4. Unlike existing technologies, and compared to the method of switching motor rotor slots by rotating the motor, this invention uses a reciprocating lifting component to drive the snap-fit ​​block to move up and down repeatedly. The snap-fit ​​block snaps into the winding slot of the motor rotor. Each time it rises, it drives the motor rotor to rotate by an angle, which facilitates the switching of slots and is beneficial for uniformly inserting blades into the motor rotor in a circumferential direction.

[0043] The present application will now be described in further detail with reference to the accompanying drawings. It should be noted that the following specific embodiments are only used to further illustrate the present application and should not be construed as limiting the scope of protection of the present application. Those skilled in the art can make some non-essential improvements and adjustments to the present application based on the above application content.

[0044] Example: Please refer to Figure 1 , Figure 3 , Figure 4 and Figure 5An inserting mechanism for a motor rotor inserting machine includes a worktable 1, a transmission assembly 6 on the top of the worktable 1, a vertical plate 7 on the top left side of the worktable 1, a cutting assembly 4 for cutting insulating tape and a pressing assembly 5 for pressing down the cut insulating sheets between the vertical plate 7 and the transmission assembly 6; a fixing plate 23 is fixedly installed on the top of the vertical plate 7, a support seat 17 is fixedly installed on the bottom left side of the fixing plate 23, a support unlocking assembly 9 is provided between the support seat 17 and the pressing assembly 5, and the middle of the fixing plate 23... A guide plate 13 is fixedly inserted through the support. The top of the guide plate 13 is flush with the top of the support 17, which facilitates the insertion of the insulating sheet from the guide plate 13 into the support 17. A guide groove 14 is provided on the top of the guide plate 13, and an insertion groove 15 is provided in the middle of the guide plate 13. A limit groove 18 is provided on the top of the support 17. An mounting plate 11 is fixedly installed on the rear side of the fixing plate 23. An air blowing dust removal component 8 is provided between the pressing component 5 and the mounting plate 11. The pressing component 5 and the air blowing dust removal component 8 work together to blow air to clean the slot of the motor rotor.

[0045] In use, the transmission component 6 is used to synchronously drive the cutting component 4 and the pressing component 5. The cutting component 4 is used to cut the fed insulation sheet, the pressing component 5 is used to press down the cut insulation sheet, the guide groove 14 is used to guide the fed insulation sheet, ensuring that the insulation sheet is accurately delivered to the bottom of the cutting component 4, and the air blowing dust removal component 8 is used to blow air to clean the slot of the motor rotor, avoiding the problem of impurities and dust affecting the insertion of insulation.

[0046] Please see Figure 1 and Figure 2 A conveyor 2 for feeding and conveying the motor rotor is provided on the left side of the workbench 1. A lifting assembly 3 is provided in the middle of the left side of the workbench 1. The lifting assembly 3 includes a fixed block 33 fixedly installed in the middle of the left side of the workbench 1. A telescopic cylinder 32 is fixedly installed at the top center of the fixed block 33. A lifting seat 31 is fixedly connected to the output end of the telescopic cylinder 32. The lifting seat 31 movably passes through the top of the conveyor 2. The conveyor 2 is existing technology. The conveyor 2 includes a fixed bracket, a conveyor belt, a transmission roller and a drive motor. The drive motor drives the transmission roller to rotate. There are two conveyor belts, symmetrically arranged outside the transmission roller. There is a gap between the two conveyor belts to facilitate the passage of the lifting seat 31. The conveyor belt conveys the motor rotor. The lifting seat 31 is used to support the motor rotor. A control module is provided inside the workbench 1. The control module is used to control the stable operation of each mechanism.

[0047] In use, the conveyor 2 transports the motor rotor from the previous process from front to back to directly below the supporting unlocking component 9. At this time, the output end of the telescopic cylinder 32 extends, causing the lifting seat 31 to rise, and simultaneously driving the motor rotor to move upward.

[0048] Please see Figure 3 and Figure 4 The transmission assembly 6 includes a fixed base 65 fixedly installed on the rear side of the top of the workbench 1. A servo motor 61 is fixedly installed on the fixed base 65. The output end of the servo motor 61 rotates through the fixed base 65. A first mounting base 62 is fixedly installed on the right side of the top of the workbench 1. A linkage 63 is provided between the workbench 1 and the first mounting base 62.

[0049] Please see Figure 2 , Figure 3 and Figure 4 The linkage 63 includes a second mounting base 634 and a third mounting base 636 fixedly mounted on the top of the workbench 1. A second rotating roller 633 rotatably passes through the middle of the second mounting base 634. The rear end of the second rotating roller 633 is fixedly connected to the output end of the servo motor 61. A third rotating shaft 635 rotatably passes through the third mounting base 636. The third rotating shaft 635 and the second rotating roller 633 are driven by gears and a toothed belt. A first rotating shaft 631 rotatably passes through the top of the first mounting base 62. The first rotating shaft 631 and the second rotating roller 633 are driven by gears and a toothed belt. A connecting rod is hinged to the rear side of the first rotating shaft 631. Group 632, the end of the linkage group 632 away from the first rotating shaft 631 is rotatably connected to the movable block 12, the two ends of the third rotating shaft 635 are respectively fixedly sleeved with flywheels 64, the flywheels 64 are provided with cam grooves, the cam grooves on the two flywheels 64 are staggered, realizing the sequential operation of the cutting component 4 and the pressing component 5. The working time of the two mechanisms is staggered, which is beneficial to cut first and then press down on the cut insulating sheet. The middle of the movable block 12 slides through the limit plate 10, the limit plate 10 is fixedly connected to the fixed plate 23, and the top of the movable block 12 is fixedly connected to the plug plate 16, which is slidably connected inside the plug groove 15.

[0050] In use, when the motor rotor is lifted and moved to the working position, the servo motor 61 is started. The output end of the servo motor 61 starts to rotate, synchronously driving the second rotating roller 633 to rotate. Then, through the transmission of gears and toothed belts, the third rotating shaft 635 is driven to rotate, which in turn drives the two flywheels 64 to rotate. Through the flywheels 64, the cutting component 4 and the pressing component 5 are driven to work in sequence. The rotation of the second rotating roller 633 drives the first rotating shaft 631 to rotate through the transmission of gears and toothed belts, and at the same time drives the connecting rod group 632 to rotate. This causes the movable block 12 and the plug plate 16 on it to reciprocate along the limit plate 10. The reciprocating motion of the plug plate 16 is after the pressing action of the pressing component 5. Thus, the cutting component 4 works first, and after cutting, the pressing component 5 works. Then, the plug plate 16 inserts the pressed insulating sheet into the motor rotor. A single mechanism realizes the sequential execution of three actions.

[0051] Please see Figure 3 , Figure 4 and Figure 5The slitting assembly 4 includes a first guide cylinder 41 fixedly installed on the front side of the fixed plate 23. A first connecting rod 42 is slidably connected inside the first guide cylinder 41. A first limiting pin 43 is fixedly fixed at the bottom of the first connecting rod 42 and slidably connected inside the cam groove of the flywheel 64 located on the front side. A first fixing arm 44 is fixedly connected to the top of the first connecting rod 42. A slitting blade 45 for slitting the insulating tape is provided on the first fixing arm 44. The slitting blade 45 is detachable for easy disassembly and maintenance.

[0052] When in use, the flywheel 64 located on the front rotates, which drives the first limit pin 43 and the first connecting rod 42 on it to move up and down through the cam groove on the flywheel 64. Simultaneously, it drives the first fixed arm 44 and the slitting blade 45 on it to move up and down. When the slitting blade 45 moves downward, it realizes the slitting of the insulating sheet. When it moves upward, the slitting blade 45 resets.

[0053] Please see Figure 3 , Figure 5 and Figure 6 The air blowing dust removal assembly 8 includes a base plate 85 fixedly installed on the mounting plate 11. An airbag 83 is fixedly installed on the top of the base plate 85. A one-way air intake valve is installed on the airbag 83, which allows outside air to enter the airbag 83 in one direction. A second lower pressure plate 82 is attached to the top of the airbag 83. A lower pressure arm 81 is fixedly installed on the top of the second lower pressure plate 82. The lower pressure arm 81 is fixedly connected to the first fixed arm 44. An air pipe 84 is fixedly connected to the top left side of the airbag 83. The air pipe 84 is a flexible hose. A top plate 86 is fixedly connected to the end of the air pipe 84 away from the airbag 83. An air nozzle 87 is installed on the left side of the top plate 86. The air nozzle 87 is connected to the air pipe 84.

[0054] In use, when the first fixed arm 44 and the slitting blade 45 move downwards, they simultaneously drive the lower pressure arm 81 and the second lower pressure plate 82 on it to move downwards. At the same time, the air bag 83 is compressed, and the gas in the air bag 83 is delivered to the air nozzle 87 through the air pipe 84. Then, the gas is blown out through the air nozzle 87. The blown gas cleans the slot of the motor rotor, effectively removing debris and impurities from the slot of the motor rotor. This prevents impurities and debris from affecting the insertion of the insulating sheet and ensures the smooth insertion of the insulating sheet.

[0055] Please see Figure 3 , Figure 4 and Figure 7The pressing assembly 5 includes a second guide cylinder 51 fixedly connected to the rear side of the fixed plate 23. A second connecting rod 52 is slidably connected inside the second guide cylinder 51. A second limiting pin 53 is fixedly fixed at the bottom of the second connecting rod 52 and slidably connected inside the cam groove of the flywheel 64 located on the rear side. A second fixing arm 54 is fixedly installed at the top of the second connecting rod 52. A through hole is opened at the upper part of the fixed plate 23. A movable plate 55 is fixedly connected after the second fixing arm 54 moves through the through hole. An installation arm 58 is fixedly connected on the movable plate 55. A first pressing plate 56 for pressing down the cut insulating sheet is fixedly connected to the front side of the installation arm 58. A fixing head 57 is fixedly connected to the top of the movable plate 55. A reciprocating lifting component 59 is provided on the fixing head 57.

[0056] Please see Figure 3 , Figure 7 , Figure 8 and Figure 11 The reciprocating lifting component 59 includes a rocker arm 591 rotatably connected to a fixed head 57. A protrusion 592 is fixedly connected to the center of the bottom of the rocker arm 591. A connecting plate 593 is rotatably connected to the bottom of the rocker arm 591. A base 594 is fixedly installed on the right side of the connecting plate 593. The base 594 is fixedly connected to the mounting plate 11. Two guide rods 597 movably pass through the base 594. A top block 595 is fixedly installed on the top of the two guide rods 597. The top of the top block 595 is flush with the bottom of the protrusion 592. The parts fit together, and a spring 596 is provided between the top block 595 and the base 594. The bottom of the two guide rods 597 are fixedly connected to the lifting plate 598. The left side of the lifting plate 598 is fixedly connected to the mounting head, and a fixing pin 21 is fixedly installed on the mounting head. A snap-fit ​​block 20 is rotatably installed on the fixing pin 21. One side of the snap-fit ​​block 20 is an arc surface, and the other side is a straight surface. A torsion spring 22 is fixedly sleeved on the fixing pin 21. The torsion spring 22 is used to realize the unidirectional rotation of the snap-fit ​​block 20 around the fixing pin 21.

[0057] In use, after the insulating sheet is cut, the second connecting rod 52 and the second fixed arm 54 on it move up and down under the drive of the flywheel 64 located at the rear. This drives the movable plate 55 and the mounting arm 58 on it to move up and down, which in turn drives the first pressing plate 56 to move up and down. When the first pressing plate 56 moves downward, it presses the cut insulating sheet into the limiting groove 18. The limiting groove 18 facilitates the precise alignment between the insulating sheet and the motor rotor slot.

[0058] Please see Figure 7 , Figure 9 and Figure 10The unlocking support assembly 9 includes two mounting boxes 92 fixedly installed on the top of the support base 17. Each mounting box 92 has a circular hole in its center. Two sliding grooves 94 are symmetrically opened on one side of the top of the two mounting boxes 92. A slider 95 is slidably connected inside the sliding groove 94. A pull rod 97 is fixedly connected to the slider 95. The two pull rods 97 on the same mounting box 92 move through the housing of the mounting box 92 and are fixedly connected to a linkage plate 98. An arc-shaped head 99 is fixedly connected to one side of the linkage plate 98. A second spring 96 is sleeved on the outside of the pull rod 97. The second spring 96 is located between the slider 95 and the inner wall of the sliding groove 94. The top of the two sliders 95 on the same mounting box 92 is fixedly connected to a support plate 93 for supporting the insulating paper. Unlocking rods 91 are fixedly installed on both sides of the movable plate 55. A top cover 19 is fixedly installed on the left side of the support base 17.

[0059] During use, the support plate 93 is extended during cutting, supporting the insulating sheet and providing additional support to ensure a clean cut. After cutting, when pressing down on the cut insulating sheet, the unlocking rod 91 moves downward and inserts through the circular hole on the mounting box 92. The arc-shaped surface at the bottom of the unlocking rod 91 contacts the arc-shaped head 99. As the unlocking rod 91 is inserted, it drives the arc-shaped head 99 and the linkage plate 98 to move away from the movable plate 55 until the support plate 93... The plate retracts onto the mounting box 92, simultaneously driving the pull rod 97 and its slider 95 to move away from the movable plate 55, simultaneously compressing the second spring 96. At this time, the support plate 93 releases its support for the insulating sheet. As the movable plate 55 presses down, the cut insulating sheet is pressed into the limiting groove 18. When the movable plate 55 rises, it simultaneously drives the unlocking rod 91 to rise, releasing the pressure of the unlocking rod 91 on the arc-shaped head 99. At this time, under the restoring force of the second spring 96, the support plate 93 extends back to support the insulating sheet.

[0060] Meanwhile, the reciprocating lifting component 59 can achieve intermittent rotation of the motor rotor, facilitating the sequential insertion of plates by rotating the motor rotor circumferentially. The specific principle is as follows: When the locking block 20 rotates unidirectionally under the action of the torsion spring 22, the arc surface of the locking block 20 fits against the outer wall of the motor rotor when the lifting assembly 3 lifts the motor rotor upward. As the motor rotor rises to fit against the bottom of the upper cover 19, the locking block 20 is precisely engaged in the winding groove of the motor rotor, achieving accurate positioning of the motor rotor. At this time, the top notch of the motor rotor is exactly on the left side of the limiting groove 18.

[0061] At this time, as the movable plate 55 moves down, it simultaneously drives the fixed head 57 and one end of the rocker 591 to move down, and simultaneously drives the protrusion 592 to move down, which in turn drives the top block 595 and the guide rod 597 on it to move down. At the same time, it drives the lifting plate 598 and the fixed pin 21 and the locking block 20 on it to move down. Since the bottom of the locking block 20 is curved, when the locking block 20 moves down, the movable plate 55 moves up, and under the action of the restoring force of the first spring 596, the locking block 20 is indirectly driven to move up, thus realizing the up and down reciprocating motion of the locking block 20 through the reciprocating lifting component 59.

[0062] The locking block 20 has a gradually increasing structure near the fixing pin 21. The locking block 20 is detachable, and different locking blocks 20 can be replaced according to different motor rotors. When the locking block 20 moves upward, since the top of the locking block 20 is flat, it pushes the motor rotor to rotate at a certain angle. At this time, the slot into which the insulating sheet is inserted is rotated out of the working position, and the next slot without the insulating sheet is rotated into the working position. At this time, the gradually increasing root of the locking block 20 contacts the edge of the lifting seat 31. Through compression, the locking block 20 overcomes the elastic force of the torsion spring 22 and deflects away from the motor rotor. At this time, the locking block 20 is disengaged from the winding slot of the motor rotor. When the locking block 20 moves downward, under the action of the elastic force of the torsion spring 22, the locking block 20 is locked into the winding slot of the motor rotor again. The above steps are repeated, thereby realizing the circumferential rotation of the motor rotor, which facilitates the circumferential rotation and insertion of the insulating sheet without the need to use the motor to drive the motor rotor to rotate.

[0063] Please see Figure 12 A method for inserting rotor laminations into an electric motor includes the following steps:

[0064] S1. Rotor loading: First, the motor rotor is transported from front to back using the conveyor 2. The conveyor stops at the middle of the conveyor 2. At this time, the lifting assembly 3 is used to lift the motor rotor until the top of the motor rotor is in contact with the bottom of the cover 19. At this time, the snap-fit ​​block 20 is snapped into the winding groove of the motor rotor to achieve accurate positioning of the motor rotor. At this time, the top notch of the motor rotor is exactly on the left side of the limiting groove 18, thus completing the loading of the motor rotor.

[0065] S2, Insulation tape slitting: After the motor rotor is loaded, the automatic feeder will convey the insulation tape along the guide groove 14. After the loading is completed, the flywheel 64 located at the front rotates under the drive of the transmission component 6. The cam groove on the flywheel 64 drives the first limit pin 43 and the first connecting rod 42 on it to move up and down. Simultaneously, it drives the first fixed arm 44 and the slitting blade 45 on it to move up and down. When the slitting blade 45 moves downward, it realizes the slitting of the insulation sheet. When it rises, the slitting blade 45 resets. The slitting component 4 is used to cut the insulation tape into fixed lengths.

[0066] S3. Air cleaning: During the cutting process described above, when the first fixed arm 44 and the slitting blade 45 move downwards, they simultaneously drive the lower pressure arm 81 and the second lower pressure plate 82 on it to move downwards. At the same time, the air bag 83 is compressed, and the gas in the air bag 83 is delivered to the air nozzle 87 through the air pipe 84. Then, the gas is blown out through the air nozzle 87. The blown gas cleans the slot of the motor rotor, effectively removing debris and impurities from the slot of the motor rotor. This prevents impurities and debris from affecting the insertion of the insulating sheet and ensures the smooth insertion of the insulating sheet.

[0067] S4. Aligning the insert: After the air cleaning is completed, under the drive of the transmission component 6, after the insulating sheet is cut, the second connecting rod 52 and the second fixed arm 54 on it move up and down reciprocally under the drive of the flywheel 64 located on the rear side. This simultaneously drives the movable plate 55 and the mounting arm 58 on it to move up and down reciprocally, and then drives the first lower pressure plate 56 to move up and down reciprocally. When the first lower pressure plate 56 moves downward, it presses the cut insulating sheet into the limiting groove 18. The limiting groove 18 facilitates the precise alignment between the insulating sheet and the motor rotor slot. Then, under the push of the insertion plate 16, the insulating sheet is inserted into the motor rotor slot, realizing the insert installation.

[0068] S5. Material unloading and conveying: After installation, the lifting assembly 3 lowers the installed motor rotor into the conveyor 2, and uses the conveyor 2 to transport it to the next process step.

[0069] The embodiments described above are merely examples of several implementations of the present invention, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the present invention. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of the present invention, and these modifications and improvements all fall within the scope of protection of the present invention.
