[0059] In the stator and rotor assembly process of existing motors, especially large motors, the stator and rotor are positioned up and down by a stator and rotor positioning mechanism before assembly. However, the automatic loading and unloading of the stator and rotor is often transported directly to the positioning station manually or by a crane. Due to the substandard transportation accuracy of the manual and crane transportation, the positioning and assembly efficiency of the stator and rotor is low and cannot meet production needs.

[0060] In order to solve the above problems, the present application discloses a stator-rotor assembly device to solve the above problems.

[0061] like Figure 1 As shown, this embodiment provides a stator and rotor automatic loading and unloading and assembly equipment, which is mainly used to realize the automatic loading and unloading and assembly of the motor stator and rotor. Specifically, a stator and rotor automatic loading and unloading and assembly equipment mainly includes a lower jaw 200, a stator carrier plate 300, an upper jaw 400, a stator fixing mechanism 500, a lower lifting mechanism 600 and an upper lifting mechanism 700, wherein the stator carrier plate 300 is used to fix the stator, and the stator carrier plate 300 is fixed on the lower jaw 200, and the upper jaw 400 is used to fix the rotor. The lower jaw 200 and the upper jaw 400 transport the stator and the rotor to the positioning assembly station respectively, the stator fixing mechanism 500 fixes the stator, and the lower lifting mechanism 600 and the upper lifting mechanism 700 are used to fix the stator. The upper lifting mechanism 700 positions the rotor, and at the same time the upper carrier 400 returns to the loading position. The upper lifting mechanism 700 presses the rotor down into the stator, and finally the motor is screwed. At this point, the automatic loading and assembly of the stator and rotor are completed, and the lower carrier 200 returns to the loading position to take the material. The equipment completes the automatic loading and unloading of the product through the lower carrier 200 and the upper carrier 400, and does not form interference during the assembly process, and completes the automatic assembly of the stator and rotor through the lower lifting mechanism 600 and the upper lifting mechanism 700, which greatly improves the production efficiency.

[0062] Specifically, Figure 1As shown, the automatic loading and unloading and assembly equipment for stators and rotors also includes a working platform 101 and a frame 102. The working platform 101 is arranged on the frame 102. A transplanting rack 104 is arranged on the working platform 101. A liftable foot cup and a pulley are arranged at the bottom of the frame 102. When fixedly placed, the foot cup touches the ground before the pulley, which is used for fixed support of the equipment. When moving, the foot cup is retracted until the pulley touches the ground first, which is convenient for moving the equipment.

[0063] like Figure 2 As shown, the downloading tool 200 is slidably connected to the working platform 101 and is used to carry the stator. The downloading tool 200 includes an upper plate 206 and a lower plate 207. The lower plate 207 close to the working platform 101 is provided with a positioning hole 201, and the upper plate 206 away from the working platform 101 is provided with a positioning pin 202 and a U-shaped hole 203. The U-shaped hole 203 is used to screw the upper plate 206 and the lower plate 207 together. The lower plate 207 is provided with an adjusting mechanism 204, and the position of the upper plate 207 relative to the lower plate 206 can be adjusted by the adjusting mechanism 204. A through hole 205 is provided in the middle of the downloading tool 200, and the through hole on the upper plate 206 is smaller than the through hole on the lower plate 207. When the stator is located on the carrier 200, when the stator is located on the downloading tool 200, the through hole 205 is concentric with the cylinder of the stator body. The downloading tool 200 can be used to match different products, which improves the flexibility of the equipment. The downloading tool 200 is driven by a motor and will not be repeated.

[0064] like Figure 3 As shown, the stator carrier 300 is used to transport and position the stator. The stator is placed on the bottom plate 301 of the stator carrier 300. The bottom plate 301 is provided with pin holes, which match the positioning pins 202 on the lower tool 200. The bottom plate 301 is also provided with positioning blocks 302. The positioning blocks 302 are arranged around the stator, and the stator body is a cylinder. The inner wall of the positioning block 302 here matches the curvature of the stator body, so that the stator is positioned in the horizontal direction and cannot be displaced. At the same time, a buckle is provided on the outer wall of the stator, and a positioning column 303 is provided on the bottom plate 301. The positioning column 303 can be inserted into the buckle, which increases the stability of the stator. At the same time, a hanging buckle 304 is also provided on the bottom plate 301 for easy crane lifting.

A triangular support frame 407 is fixedly connected to the adjacent inner walls thereof to increase the stability between the carrier transverse plate 401 and the carrier vertical plate 406. The carrier vertical plate 406 is slidably connected to the transverse plate 407. Buffer blocks 409 are fixedly provided on both sides of the carrier vertical plate 406 facing the transverse plate 407. Buffers 408 are provided on the upper and lower sides of the transverse plate 407 facing the carrier vertical plate 406, so that there is a buffer stage when the mechanism moves up and down, thereby avoiding direct collision of the mechanism and increasing the stability of the equipment. The upper carrier 400 is driven by a motor, and the upper carrier 400 can move in the X direction. The motor is a prior art and will not be described in detail.

[0066] like Figure 5 As shown, the stator fixing mechanism 500 includes a positioning platform 501, a circular notch is provided on the positioning platform 501, a pushing mechanism 502 is provided around the circular notch on the positioning platform 501, a driving end of the pushing mechanism 502 is fixedly connected to a pressure plate 503, and the pushing mechanism 502 can move the pressure plate 503 toward the center of the circular notch, the positioning platform 501 is slidably connected to a gantry 504, and the gantry 504 is fixedly connected to the working platform 101, and the stator fixing mechanism 500 is driven by a motor, and the fixing mechanism 500 can be carried in the X direction, wherein the motor is a prior art and will not be described in detail.

[0067] like Figure 6As shown, the lower lifting mechanism 600 includes a connecting plate 601, which is fixedly connected to the working platform 101, and a lifting mechanism 602 and a rising mechanism 603 are fixedly connected on both sides of the bottom. The lifting mechanism 602 is fixedly connected to the frame 102 at the bottom of the working platform 101 through a triangular plate 604. A supporting plate 605 is provided at the driving end of the lifting mechanism 602, and a lower ejector rod 606 is fixedly connected to the supporting plate 605. The driving end of the rising mechanism 603 is fixedly connected to a rising platform 607, and a guide sleeve 608 is fixedly connected to the rising platform 607. The guide sleeve 608 and the lower ejector rod 606 are concentric, and the guide sleeve 608 and the lower ejector rod 606 can pass through the connecting plate 601 and move up and down. The guide sleeve 608 is always at the top of the lower ejector rod 606 during the movement, so as to realize top guidance and make the movement of the lower ejector rod 606 more stable. Here, the lower lifting mechanism 600 is driven by a motor, and the rising mechanism 603 is driven by a cylinder.

[0068] like Figure 7 As shown, the upper lifting mechanism 700 includes a lifting horizontal plate 701 and a lifting vertical plate 702. The lifting vertical plate 702 is slidably connected to the transplanting frame 104 up and down. The lifting horizontal plate 701 and the lifting vertical plate 702 are fixedly connected by a tripod. The principle is the same as that of the upper carrier 400 and is not repeated here. The bottom of the lifting horizontal plate 701 is connected to a quick-change bottom plate 703. The quick-change bottom plate 703 is provided with an upper push rod 704. The upper push rod 704 is provided with an elastic mechanism inside. The push rod inside the upper push rod 704 has a certain elasticity. The lower pressure rod 705 is arranged around the upper push rod 704, and the lower pressure rod 705 is fixedly connected to the quick-change base plate 703. Meanwhile, the position of the quick-change base plate 703 relative to the lifting cross plate 701 is adjustable (the principle is the same as that of the upper plate 206 relative to the lower plate 207, which will not be repeated). The other end of the lower pressure rod 705 is detachably connected to the pressure block 706, and the pressure block 706 can be replaced according to the product model to adapt to different models and increase the flexibility of the equipment. Here, the upper lifting mechanism 700 is driven by a motor.

[0069] In summary, the downloading tool 200 is slidably connected to the working platform 101, and the downloading tool 200 can move in the X direction. Initially, the downloading tool 200 is located at the loading position, that is, the downloading tool 200 is on the positive side of the X direction on the working platform 101, and a stator fixing mechanism 500 is provided on the working platform 101 on the side opposite to the downloading tool 200 in the opposite direction of the X direction. The transplanting rack 104 is fixedly established on the working platform 101 and is located on the Y direction side of the downloading tool 200 and the stator fixing mechanism 500. The rack is L-shaped, and a track is respectively provided on the transplanting rack 104 in the X direction and the Z direction. The upper carrier 400 and the upper lifting mechanism 700 are respectively slidably connected to the transplanting rack 104 through two tracks. Specifically, the upper carrier 400 is connected to the transplanting rack 104 through the X direction. The track in the direction is slidably connected to the transplanting frame 104, the upper carrier 400 can move in the X direction, and the upper carrier 400 is located above the lower carrier 200, and when the lower carrier 200 and the upper carrier 400 are both in the loading position, that is, the lower carrier 200 is at the maximum stroke end in the positive direction of the X direction, and the upper carrier 400 is at the maximum stroke end in the positive direction of the X direction. At this time, the lower carrier 200 and the upper carrier 400 do not interfere with each other in the Z direction. Because the product is heavy, it is necessary to hoist and load it from the top of the equipment. The lower carrier 200 and the upper carrier 400 are staggered in the Z direction to facilitate loading and do not interfere with assembly. The upper lifting mechanism 700 is slidably connected to the transplanting frame 104 through the track in the Z direction, and the track in the Y direction does not interfere with the track in the X direction.

[0070] Secondly, when the download tool 200 moves to the working position, that is, the download tool 200 is located under the stator fixing mechanism 500, a positioning mechanism 103 is provided inside the frame 102, and the driving end of the positioning mechanism 103 can be lifted up to expose the surface of the working platform 101, and at the same time, the driving end of the positioning mechanism 103 passes through and exposes the positioning hole 201 on the download tool 200, so as to realize the precise positioning of the download tool 200. At this time, the circular notch on the stator fixing mechanism 500 is concentric with the through hole 205 on the download tool 200, the pressure plate 503 on the stator fixing mechanism 500 extends out and is located above the stator upper plane 305, and the positioning platform 501 is pressed down to fix the stator on the download tool 200 in the Z direction.

[0071] Secondly, when the upper carrier 400 moves to the working position, that is, the upper carrier 400 is located above the stator fixing mechanism 500, at this time, the circular notch on the stator fixing mechanism 500 is concentric with the circle formed by the arc of the U-shaped notch on the upper carrier 400. When the upper carrier 400 is loaded, because the stator body is composed of cylinders of different diameters, the cylinder on the stator body with the same diameter as or slightly smaller than the arc diameter of the U-shaped notch on the upper carrier 400 passes through the U-shaped notch on the upper carrier 400, and the cylindrical part on the stator body with a larger diameter than the arc of the U-shaped notch on the upper carrier 400 and smaller than the circular groove 403 is accommodated in the circular groove 403. The lower half of the stator structure is limited to move in the horizontal direction. The limit assembly 404 matches the outer structure of the upper half of the stator and is close to the outer structure of the stator to limit the horizontal movement of the upper half of the stator structure. The limit assembly 404 is provided with a latch 405, which can be inserted into the threaded hole on the outer edge of the rotor (the threaded hole on the outer edge of the rotor matches the threaded hole on the upper plane 305 of the stator). At this time, the central axis holes at both ends of the stator are concentric with the circle formed by the arc of the U-shaped notch on the upper carrier 400. The three limit fixations make the rotor transportation process more stable and the accuracy is higher when it arrives at the working position, which improves the accuracy of the subsequent assembly.

[0072] The upper lifting mechanism 700 is slidably connected to the transplanting frame 104 and is located directly above the stator fixing mechanism 500. The upper lifting mechanism 700 can move in the Z direction. Specifically, a cylindrical lifting rod is provided inside the upper lifting rod 704, and the top of the lifting rod is a cone. When the upper carrier 400 reaches the working position, the upper lifting rod 704 is concentric with the central axis hole on the stator, and when the upper lifting mechanism 700 descends, the cone at the top of the lifting rod can partially enter the central axis hole of the stator. When the lifting rod abuts against the central axis hole of the stator, the lower pressure rod 705 is located above the upper surface 708 of the rotor and is still some distance away from the upper surface 708 of the rotor. The distance here is equal to or slightly greater than the depth of the groove on the upper carrier 400.

[0073] At the same time, when the upper lifting mechanism 700 descends, the lifting mechanism 602 on the lower lifting mechanism 600 drives the lower lifting rod 606 to lift through the support plate 605. The lower lifting mechanism 600 is located directly below the lower tool 200 and is placed inside the frame 102 with a hidden design. At this time, the lower lifting rod 606 is concentric with the through hole 205 on the lower tool 200. The top of the lower lifting rod 606 is a cone. Since the center of the stator is a cylindrical through hole, the lower lifting rod 606 can be lifted through the lower tool 200 to abut the central axis hole of the stator, and the top part of the lower lifting rod 606 enters the central axis hole of the stator. At this point, the automatic loading and unloading of the stator and rotor and the automatic loading and automatic center positioning of the assembly equipment are completed.

[0074] In summary, since the equipment assembles large motors, the stator and rotor have a large mass, and are loaded and unloaded by a crane. First, the crane loads the stator and rotor separately from the top of the equipment. The stator has been fixed on the bottom plate 301 before loading. The positioning block 302 and the positioning column 303 fix the stator in the horizontal direction. The crane lifts the bottom plate 301 and places it on the download tool 200. The positioning pin 202 on the download tool 200 is inserted into the pin hole on the bottom plate 301, and the stator is stably placed on the download tool 200, realizing automatic loading of the stator. Secondly, the crane lifts the rotor and places it on the upper carrier 400. The limit assembly 404 on the upper carrier 400 realizes the horizontal position of the upper half of the rotor. The circular groove 403 realizes the fixation of the lower half of the rotor in the horizontal direction, and the pin 405 on the limit assembly 404 can be inserted into the threaded hole on the rotor, thereby further realizing the fixation. At this point, the automatic loading of the stator and the rotor is completed. At this time, the stator and the through hole 205 on the downloader 200 are concentric, and the circular groove 403 on the rotor and the upper carrier 400 are concentric. Because the downloader 200 and the upper carrier 400 do not interfere with each other in the Y direction at the loading position, the automatic loading of the downloader 200 and the upper carrier 400 is not affected, thereby realizing automatic loading of products, improving the accuracy of assembly of the stator and the rotor, and improving the efficiency of equipment assembly.

[0075] When the stator and rotor are loaded, the button is manually started, and the downloading tool 200 and the upper carrier 400 move to the working position. When the downloading tool 200 and the upper carrier 400 arrive at the working position, the positioning mechanism 103 is lifted and inserted into the positioning hole 201 to achieve accurate positioning of the downloading tool 200. Specifically, when the downloading tool 200 and the upper carrier 400 arrive at the working position, below the downloading tool 200, the through hole 205 on the downloading tool 200 is concentric with the lower ejector rod 606 on the lower ejector mechanism 600, and above the downloading tool 200, the through hole 205 on the downloading tool 200 is concentric with the circular notch on the stator fixing mechanism 500, the through hole 205 on the downloading tool 200 is concentric with the circular groove 403 on the upper carrier 400, and the through hole 205 on the downloading tool 200 is concentric with the upper ejector rod 704 on the upper ejector mechanism 700. At this point, the automatic positioning of the product is completed, which improves the accuracy of the assembly of the stator and rotor and improves the efficiency of the assembly of the equipment.

[0076] When the stator and the rotor are positioned before assembly, the pressure plate 503 on the stator fixing mechanism 500 extends out and presses down, and the cover is pressed on the upper plane 305 of the stator, and the stator is pressed tightly between the pressure plate 503 and the lower carrier 200. After that, the lower lifting mechanism 600 and the upper lifting mechanism 700 move toward the upper carrier 400 at the same time until the lower push rod 606 and the upper push rod 704 respectively abut against the two ends of the rotor center axis. At this time, there is no contact between the lower pressure rod 705 and the upper surface 708 of the rotor, and the cone parts of the top plates of the lower push rod 606 and the upper push rod 704 enter the central axis hole of the rotor to achieve clamping of the rotor in the Y direction. At this time, the center positioning of the stator and the rotor is completed, and the stator and the rotor are concentric.

[0077] Then, the upper lifting mechanism 700, the upper carrier 400 and the lower lifting mechanism 600 descend synchronously until the bearing 707 on the rotor enters the bearing chamber of the stator (not shown in the figure), and the depth of the bearing 707 entering the bearing chamber of the stator is greater than the distance between the lower pressure rod 705 and the upper surface 708 of the rotor.

[0078] Then, the lower lifting mechanism 600 lifts the mechanism upward. Since the upper ejector rod 704 is retractable, the lower lifting mechanism 600 lifts the upper surface 708 of the rotor to abut against the lower pressure rod 705. At the same time, the bearing 707 is not completely separated from the bearing chamber, and the rotor body accommodated in the circular groove 403 of the upper carrier 400 is separated from the circular groove 403, and the lower surface 708 of the rotor is separated from the circular groove 403. At this time, the upper carrier 400 withdraws from the working position, that is, the upper carrier 400 moves in the positive direction of X and returns to the loading position. The stator fixing mechanism 500 rises to be separated from the upper surface 305 of the stator, and the pressure plate 503 retracts to the outside of the main body where the upper surface 305 of the stator is located. The bearing 707 can realize the horizontal positioning of the rotor through the bearing chamber, and the rotor realizes the vertical positioning of the rotor through the upper ejector rod 704 and the lower ejector rod 606, and at this time the rotor is concentric with the stator.

[0079] Finally, the upper lifting mechanism 700 is pressed down, and the upper lifting mechanism 700 presses the rotor into the stator through the lower pressing rod 705, and the positioning mechanism 103 retreats. At the same time, the upper lifting mechanism 700 and the lower lifting mechanism 600 return to the loading position, and then the lower tool 200 returns to the loading position and is manually screwed.

[0080] It should be noted that due to different product models, when the upper push rod 704 initially abuts the central axis hole, the distance from the upper surface 708 of the rotor to the lower pressure rod 705 will change. Therefore, different models of pressure heads can be replaced to change the distance from the upper surface 708 of the rotor to the lower pressure rod 705, and the quick-change bottom plate 703 can also be adjusted to adjust the position of the pressure head on the upper surface 708 of the rotor. In addition, after the product is loaded, it is necessary to manually place the wave pad into the stator, and a wave pad tooling is provided on the working platform 101, and the material is taken from the wave pad tooling manually.

[0081] This equipment basically uses motors as drivers. The mass of the products to be assembled is relatively large, and the assembly precision is relatively high. The motor has higher precision than the cylinder, or a driver more suitable than the motor can be used. No limitation is made here.

For those skilled in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the embodiments here.
