Description

Technical Field

[0001] This invention relates to the field of paper insertion equipment for motor stator slots, specifically to an automatic paper insertion device and method for the stator slots of an AC servo motor. Background Technology

[0002] Currently, the main function of a motor paper inserter is to insert insulating paper of a certain length into the stator core slots to wind copper wire. The inner wall of the stator core has multiple slots evenly arranged circumferentially for winding copper wire. Since both the copper wire and the core are conductors, insulators are added inside the core slots to isolate the copper wire and prevent electrical conductivity issues.

[0003] However, existing paper insertion machines typically require manual handling of the stator slots before inserting insulating paper. The stator material is manually moved one by one from the storage bin to the insertion position on the slotting machine. After processing one workpiece, it must be manually removed and the next workpiece placed. This not only results in low mechanization and high labor intensity, but also poses a risk of accidental drops and injuries, especially for medium and large servo motor stator slots during handling. Therefore, this invention proposes an automatic paper insertion device and method for AC servo motor stator slots to solve the above problems. Summary of the Invention

[0004] To address the shortcomings of existing technologies, this invention provides an automatic paper insertion device and method for the stator slot of an AC servo motor. This solves the problem that both stator paper feeding and paper removal operations require manual handling. After processing one workpiece, it must be manually removed and placed before the next workpiece can be inserted again. This not only results in low mechanization and high workload, but also poses a risk of accidental drops and injuries to workers, especially with medium and large servo motor stator slots during handling.

[0005] To achieve the above objectives, the present invention provides the following technical solution: an automatic paper insertion device for the stator slot of an AC servo motor, comprising a housing, an insulating paper rack disposed on the side wall of the housing, and a paper insertion mechanism disposed on the front of the housing for inserting paper into the stator slot of the servo motor.

The T-shaped slider is fixedly connected to one end of the first guide rod and is slidably connected inside one of the T-shaped grooves.

[0009] Preferably, the second clamping assembly includes a second clamping plate, a second rack, a second guide rod, and a guide T-block.

[0018] Beneficial effects

[0019] This invention provides an automatic paper insertion device and method for the stator slot of an AC servo motor. Compared with the prior art, it has the following advantages:

[0020] 1. An automatic paper insertion device and method for the stator slot of an AC servo motor, comprising a feeding mechanism for conveying the AC motor stator to the paper insertion mechanism on one side of the housing, an loading mechanism for conveying the AC servo motor stator into the feeding mechanism on the right side of the feeding mechanism, and a unloading mechanism for conveying the AC servo motor stator after paper insertion on the left side of the feeding mechanism. A detachment mechanism for separating the AC servo motor stator from the paper insertion mechanism is provided on the front of the housing. A guide bracket for supporting the AC servo motor stator during paper insertion is provided on the front of the housing below the detachment mechanism. T-shaped grooves and mounting grooves are respectively opened on the front of the housing. This solves the problem that the stator paper insertion feeding and paper insertion removal operations both require manual handling. After processing one workpiece, it must be manually removed and placed before the next workpiece can be inserted again. This not only leads to low mechanization and high labor intensity, but also the problem that medium and large servo motor stator slots are prone to accidental drop and injury during handling.

[0021] 2. An automatic paper insertion device and method for the stator slot of an AC servo motor, wherein a feeding mechanism is set up to transport the AC servo motor stator to be inserted to a position opposite one of the anti-slip slots on the carrier plate at regular intervals. During the process of the conveyor belt moving to the end and flipping, the AC servo motor stator slides down into the placement slot by gravity, thereby realizing the purpose of transferring the AC servo motor stator from the feeding mechanism to the feeding mechanism. This process only requires manual placement of the AC servo motor stator into the placement slot, eliminating the need for long-distance transportation and other transfer operations, reducing the labor intensity of workers, and avoiding the risk of accidental drop and injury to workers while handling the AC servo motor stator, thus improving the operational safety factor.

[0022] 3. An automatic paper insertion device and method for the stator slot of an AC servo motor, wherein a feeding mechanism is set up to push the AC servo motor stator transported by the feeding mechanism into and out of the placement slot using a push rod, and the guide bracket is used to guide and lift the AC servo motor stator into the paper insertion position. The feeding process does not require manual operation. After the AC servo motor stator is inserted, the first clamping component and the second clamping component work together to remove the inserted AC servo motor stator from the paper insertion mechanism, and the feeding mechanism is used again to transfer the inserted AC servo motor stator to the unloading mechanism for delivery. The process of inserting and removing the AC servo motor stator from the paper insertion mechanism does not require manual operation. Compared with the traditional manual operation of AC servo motor stator paper insertion, this equipment has a high degree of automation and improves the efficiency of AC servo motor stator paper insertion.

[0023] 4. An automatic paper insertion device and method for the stator slot of an AC servo motor, wherein several rubber buffer protrusions are set in the feeding mechanism to impede and decelerate the AC servo motor stator during its falling and rolling process, so that the AC servo motor stator can fall smoothly onto the top of the feeding mechanism. This not only makes it easier for workers to pick up the paper, but also prevents the AC servo motor stator from falling out of the feeding mechanism due to high-speed rolling, thereby improving the safety factor.

[0037] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0038] This invention provides four technical solutions:

[0039] like Figure 1-4The first embodiment is shown: an automatic paper insertion device for the stator slot of an AC servo motor, including a housing 1, an insulating paper holder 2 disposed on the side wall of the housing 1, and a paper insertion mechanism 3 disposed on the front of the housing 1 for inserting paper into the stator slot of the servo motor. A feeding mechanism 4 for conveying the AC motor stator to the paper insertion mechanism 3 is disposed on one side of the housing 1. A loading mechanism 5 for conveying the AC servo motor stator into the loading mechanism 3 is disposed on the right side of the feeding mechanism 4, and a unloading mechanism 6 for conveying the AC servo motor stator after paper insertion is disposed on the left side of the feeding mechanism 4. A disengagement mechanism 7 for separating the AC servo motor stator from the paper insertion mechanism 3 is disposed on the front of the housing 1. A guide bracket 8 for supporting the AC servo motor stator during paper insertion is disposed on the front of the housing 1 and below the disengagement mechanism 7. T-shaped grooves 9 and mounting slots 10 are respectively opened on the front of the housing 1. There are two T-shaped grooves 9, symmetrically opened on both sides of the mounting slots 10. A control box is fixedly disposed on the side wall of the housing 1, and a controller for controlling the operation of electrical components is fixedly disposed inside the control box.

[0040] like Figure 5-6 The second embodiment is shown, and its main difference from the first embodiment is that: an automatic paper insertion device for the stator slot of an AC servo motor, the feeding mechanism 4 includes a mounting plate 41 and a first servo motor 42 fixedly mounted on the outer wall of the mounting plate 41. The output shaft of the first servo motor 42 rotatably passes through the mounting plate 41 and is fixedly connected to a carrier plate 43. Multiple placement slots 44 for placing the AC servo motor stator are evenly distributed on the outer wall of the carrier plate 43. An electric push rod 45 is fixedly mounted on the side wall of the mounting plate 41 and below the carrier plate 43. The output end of the electric push rod 45 is fixedly connected to a push rod 46 for pushing the AC servo motor stator out of the placement slots 44. There are eight placement slots 44. Furthermore, they are evenly distributed. By programming the first servo motor 42, it is controlled to rotate 45 degrees each time, and there is a ten-second interval after each rotation. The rotation speed of the first servo motor 42 and the speed of the second servo motor 53 have the following relationship: For every two placement slots 44 that the carrier disk 43 rotates, a stator carrier box 54 will be opposite to one of the placement slots 44. That is, between three adjacent stator carrier boxes 54, the middle stator carrier box 54 is not loaded with an AC servo motor stator. When the stator carrier box 54 moves to the leftmost end of the conveyor belt 52, the stator carrier box 54 is away from the conveyor belt 52 and is directly opposite one of the placement slots 44. At this time, the carrier disk 43 is in the interval after completing one rotation.

[0041] like Figure 7-9Figure 12 illustrates a third embodiment, the main difference from the first embodiment being: an automatic paper insertion device for the stator slot of an AC servo motor, wherein the disengagement mechanism 7 includes a third servo motor 71 fixedly connected inside the housing 1 and a transmission shaft assembly 72 fixedly connected to the output shaft end of the third servo motor 71 via a coupling. The transmission shaft assembly 72 includes a fixed shaft 721 and a square hole 722 opened inside the fixed shaft 721. A telescopic rod 723 is slidably connected inside the square hole 722. A connecting rod 712 is fixedly sleeved on the outer wall of the telescopic rod 723. A gear 73 is fixedly connected to the end of the transmission shaft assembly 72 away from the third servo motor 71. Limiting disks 74 are fixedly connected to both ends of the gear 73. A first clamping assembly and a second clamping assembly for clamping the AC servo motor stator are respectively provided above and below the gear 73. A connecting rod 712 is fixedly sleeved on the outer wall of the transmission shaft assembly 72. A cylinder 713 is fixedly connected to the side wall of the connecting rod 712. The cylinder 713 is fixedly connected inside the mounting groove 10. The first clamping assembly includes a first clamping plate 75, a first rack 76, a first guide rod 77, and a T-shaped slider 78. The first rack 76 is fixedly connected to the top of the first clamping plate 75, and the first rack 76 and the gear 73 are meshed at the top. The first guide rod 77 is slidably connected through the inside of the first clamping plate 75. The T-shaped slider 78 is fixedly connected to one end of the first guide rod 77. The T-shaped slider 78 is slidably connected inside one of the T-shaped grooves 9. The second clamping assembly includes a second clamping plate 79, a second rack 710, a second guide rod 711, and a guide T-shaped block. The second rack 710 is fixedly connected to the top of the second clamping plate 79, and the second rack 710 and the gear 73 are meshed. The second guide rod 711 is slidably connected through the inside of the second clamping plate 79. The guide T-shaped block is fixedly connected to one end of the second guide rod 711, and the guide T-shaped block is slidably connected in one of the T-shaped grooves 9.

[0042] like Figure 10-11 The fourth embodiment is shown, and its main difference from the third embodiment is that: an automatic paper insertion device for the stator slot of an AC servo motor, the feeding mechanism 5 includes a conveyor bracket 51 and a conveyor belt 52 disposed inside the conveyor bracket 51, and a second servo motor 53 for driving the conveyor belt 52 to rotate. The second servo motor 53 is fixedly connected to the side wall of the conveyor bracket 51. Multiple stator carrier boxes 54 are fixedly disposed at equal intervals on the top of the conveyor belt 52. When one of the stator carrier boxes 54 moves to the leftmost position, one of the placement slots 44 is opposite to the stator carrier box 54. The unloading mechanism 6 includes a guide plate 61 and a baffle 62 fixedly disposed on the top of the guide plate 61. Multiple rubber buffer protrusions 63 are evenly disposed on the top of the guide plate 61 to prevent the rolling of the AC servo motor stator.

[0043] This invention also provides a paper insertion method for an automatic paper insertion device for the stator slot of an AC servo motor, the specific method including the following steps:

[0044] Step 1, Servo motor stator loading: First, manually place the AC servo motor stator on the loading mechanism 5. The loading mechanism 5 will then transfer the AC servo motor stator to a position close to the feeding mechanism 4.

[0045] Step 2, Stator Paper Insertion Operation: The AC servo motor stator transferred from the feeding mechanism 5 is automatically transferred to the paper feeding mechanism 4, and then the AC servo motor stator is sent to the paper insertion mechanism 3 through the feeding mechanism 4, and then the insulating paper insertion operation is performed.

[0046] Step 3: Disconnecting the AC servo motor stator: Use the disconnecting mechanism 7 to remove the AC servo motor stator after paper insertion and re-feed it into the feeding mechanism 4. The feeding mechanism 4 will then send the AC servo motor stator to the unloading mechanism 6, and then transfer the AC servo motor stator to the next station. The loading mechanism 5 rotates at a low and uniform speed, and the model of the AC servo motor stator is compatible with the paper insertion mechanism 3, the feeding mechanism 4, and the loading mechanism 5.

[0047] In use, the operator stands on the lowest point of the conveyor support 51, and takes one AC servo motor stator at a time and places it in the stator carrier box 54, ensuring that one end of the AC servo motor stator is against one side of the inner wall of the stator carrier box 54. The second servo motor 53 is controlled by a program to control the conveyor belt 52 to rotate at a uniform and low speed. At the same time, the first servo motor 42 is programmed to rotate 45 degrees each time, with a ten-second pause after each rotation. The rotation speed of the first servo motor 42 and the rotation speed of the second servo motor 53 have the following relationship: for every two placement slots 44 that the carrier plate 43 rotates, one stator carrier box 54 will be opposite one of the placement slots 44, that is, between three adjacent stator carrier boxes 54, the position... The middle stator carrier box 54 is not loaded with the AC servo motor stator. When the stator carrier box 54 moves to the leftmost end of the conveyor belt 52, it is away from the conveyor belt 52 and directly opposite one of the placement slots 44. At this time, the carrier plate 43 is in the intermittent moment after completing one rotation. The AC servo motor stator slides out of the stator carrier box 54 under the action of gravity and rolls into one of the placement slots 44 on the carrier plate 43. Then, the intermittent time of the carrier plate 43 ends, and the first servo motor 42 drives the carrier plate 43 to rotate 45 degrees. At this time, the placement slot 44 containing the AC servo motor stator rotates to the position opposite to the guide bracket 8. Then, the first servo motor 42 intermittently again. Then, the controller controls the electric push rod 45 to push the push rod 46 to move. The end of push rod 46 pushes the AC servo motor stator to expose the end portion of the placement slot 44, causing the AC servo motor stator to be pushed out of the placement slot and moved onto the guide bracket 8. The guide bracket 8 is existing technology and will not be described in detail here. Then push rod 46 continues to push, and the pushing and retraction times of push rod 46 are both the initially set values. Finally, the AC servo motor stator is pushed into the paper insertion position of the paper insertion mechanism 3. After the electric push rod 45 pulls push rod 46 away from the paper insertion mechanism 3, the paper insertion mechanism 3 starts to operate. The paper insertion operation time is also controlled by the controller. As soon as the paper insertion operation is completed, the controller used to control the third servo motor 71 controls its rotation. The first rack 76 and the second rack 710 approach each other under the drive of gear 73. The first clamping plate 7 5. The second clamping plate 79 clamps the outer wall of the AC servo motor stator for the initial set time. Then, the controller of the control cylinder 713 pushes the connecting rod 712 to move. Since the two racks are restricted by the position of the limiting plate 74, when the connecting rod 712 moves to synchronously push the two racks to slide along the outer walls of the first guide rod 77 and the second guide rod 711 respectively, the length of the telescopic rod 723 in the transmission shaft assembly 72 is extended. At the same time, the first servo motor 42 drives the bearing plate 43 to rotate again, so that a stator bearing box 54 without an AC servo motor stator rotates to a position directly opposite the guide bracket 8. The AC servo motor stator after paper insertion is pushed into the empty stator bearing box 54 through the guide bracket 8.Then, the first servo motor 42 rotates again. As the loading slot containing the AC servo motor stator approaches the unloading mechanism 6, the AC servo motor stator rolls onto the guide plate 61 under gravity. Because of the several rubber buffer protrusions 63 on its top, the rolling AC servo motor stator is gradually decelerated and eventually comes to a stop. The operator can then transfer it to the next workstation.
