[0002] The stator and the rotor are two core components of a motor. During motor processing, these two components need to be assembled. Moreover, after the stator and the rotor are assembled, a fixing circlip needs to be installed on the rotor. The circlip is a commonly used connecting piece between the rotor and the stator, and its main function is to ensure the normal operation of the motor, ensure that the rotor can be firmly fixed on the stator, so as to achieve a safe, stable and efficient operation effect. The circlip is firmly fixed by being snapped into a fixed card hole. Its structural design is relatively simple, but it has an important impact on the stability and operation efficiency of the motor.

[0029] In order to make the objectives, technical solutions, and advantages of the embodiments of the present utility model clearer, the technical solutions in the embodiments of the present utility model will be clearly and completely described below. Apparently, the described embodiments are partial embodiments of the present utility model, rather than all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0030] As shown in the embodiments of the present utility model Figures 1 to 8 A stator-rotor assembling machine includes a machine table 1. A horizontal conveying mechanism 2 is provided on the machine table 1, and a liftable carrier 3 is provided on the horizontal conveying mechanism 2; a assembling platform 4 is further provided on the machine table 1 above the horizontal conveying mechanism 2. The horizontal conveying mechanism 2 moves the carrier 3 carrying the stator to below the assembling platform 4, and the carrier 3 rises to place the stator at the assembling opening of the assembling platform 4; an assembling mechanism 5 is further provided on the machine table 1 above the assembling platform 4. The assembling mechanism 5 includes a pressing cylinder 51, a base 52, an elastic reset member 53, a first magnetic attraction plate 54, and an elastic telescopic shaft 55; the base 52 is provided at the output end of the pressing cylinder 51, the first magnetic attraction plate 54 is located below the base 52, the first magnetic attraction plate 54 and the base 52 are connected by the elastic reset member 53, the fixed end of the elastic telescopic shaft 55 is provided on the base 52, and the telescopic end of the elastic telescopic shaft 55 passes through the first magnetic attraction plate 54 to sleevingly take a snap ring; the magnetic attraction surface of the first magnetic attraction plate 54 faces downward to attract the rotor. After the elastic telescopic shaft 55 and the first magnetic attraction plate 54 sequentially obtain the snap ring and the rotor, the pressing cylinder 51 drives the base 52 to press down to complete the assembly.

[0031] In this embodiment, the base 52 is in the shape of a rectangular frame, which is formed by enclosing one vertical plate and four enclosing plates. One of the lower enclosing plates is provided at the lower edge of the vertical plate, the left and right enclosing plates are provided at the left and right edges of the vertical plate, and the upper enclosing plate is provided at the upper ends of the left and right enclosing plates. The fixed end of the elastic telescopic shaft 55 is provided at the central position on the upper side surface of the lower enclosing plate of the base 52. The telescopic end of the elastic telescopic shaft 55 passes through the lower enclosing plate of the base 52, and the bottom of the telescopic end of the elastic telescopic shaft 55 is relatively located below the lower enclosing plate of the base 52. A pressure sensor is provided inside the fixed end of the elastic telescopic shaft 55. The pressure sensor can be specifically provided at any suitable position inside the fixed end of the elastic telescopic shaft 55, and is used to sense the pressure value during telescopic contact, so as to facilitate confirming whether the position movement is in place. The elastic resetting member 53 is a spring. There are two springs. The upper ends of the two springs are both provided on the lower enclosing plate of the base 52, and the lower ends of the two springs are both connected to the first magnetic attraction plate 54. The two springs are respectively located on both sides of the telescopic end of the elastic telescopic shaft 55. A through hole is formed in the first magnetic attraction plate 54. The telescopic end of the elastic telescopic shaft 55 passes through the through hole. The outer diameter of the telescopic end of the elastic telescopic shaft 55 is smaller than the inner diameter of the through hole, so as to facilitate smooth up and down movement in the through hole. Moreover, the inner diameter of the through hole is smaller than the outer diameter of the snap ring, so that when the telescopic end of the elastic telescopic shaft 55 removes the snap ring, the snap ring is restricted by the first magnetic attraction plate 54 and will not pass through the through hole.

[0032] During operation, first, the snap ring is sleeved on the telescopic end of the elastic telescopic shaft 55. During the sleeving process, the snap ring will be gradually expanded to a certain size until it is sleeved on the telescopic end of the elastic telescopic shaft 55. Then, the rotor is attracted by the first magnetic attraction plate 54, and the pressing cylinder 51 is controlled to drive the base 52 to press down, so that the rotor and the stator are pressed together, and the snap ring is pressed tightly on the rotor. Then, the pressing cylinder 51 is controlled to drive the base 52 to move up. During this process, the telescopic end of the elastic telescopic shaft 55 moves up first. Restricted by the first magnetic attraction plate 54, the snap ring gradually detaches from the elastic telescopic shaft 55 and is sleeved on the rotor. Among them, the rotor can be adsorbed on the first magnetic attraction plate 54 by means of manual feeding.

[0033] Specifically, in this embodiment, the horizontal conveying mechanism 2 is arranged on the machine table 1 in the left-right direction of the machine table 1. The horizontal conveying mechanism 2 moves the liftable carrier 3 from right to left. The assembling platform 4 is arranged above the left side of the horizontal conveying mechanism 2 through four support frames. There are two assembling ports on the assembling platform 4, so there should be two stator placement positions corresponding to those on the carrier 3. At a position on the machine table 1 close to the assembling platform 4, that is, on the left side of the machine table 1, there is a first multi-axis displacement mechanism 6. The first multi-axis displacement mechanism 6 is connected to the pressing air cylinder 51 to drive the pressing air cylinder 51 to move in the X-axis direction or the Y-axis direction. The X-axis direction is parallel to the conveying direction of the horizontal conveying mechanism 2, that is, the left-right direction of the machine table 1. The Y-axis direction is perpendicular to the conveying direction of the horizontal conveying mechanism 2, that is, the front-back direction of the machine table 1, so as to drive the pressing air cylinder 51 to move relative to the front, back, left, and right positions of the machine table 1, and further adjust the positions of the base 52 and the corresponding components on the base 52.

[0034] Among them, the first multi-axis displacement mechanism 6 includes two relatively arranged first inverted U-shaped brackets 61. The two first inverted U-shaped brackets 61 are arranged at left and right intervals. The bottom ends of the two first inverted U-shaped brackets 61 are arranged on the machine table 1 in the front-back direction of the machine table 1. A first cross bar 62 is connected between the top rods of the two first inverted U-shaped brackets 61. The two ends of the first cross bar 62 are correspondingly slid on the top rods of the two first inverted U-shaped brackets 61. The first cross bar 62 slides in the Y-axis direction. The pressing air cylinder 51 slides on the first cross bar 62, and the pressing air cylinder 51 slides in the X-axis direction.

[0035] Furthermore, first slide rails are correspondingly arranged on the opposite side surfaces of the top rods of the two first inverted U-shaped brackets 61. First sliders are slid on both first slide rails. One of the first sliders is driven to slide by a first motor, and the first motor is arranged on the top rod of the first inverted U-shaped bracket 61 on the same side. The two ends of the first cross bar 62 are correspondingly connected to the two first sliders. A second slide rail is arranged on the first cross bar 62. A second slider driven to slide by a second motor is slid on the second slide rail. The fixed end of the pressing air cylinder 51 is connected to the second slider.

[0036] Specifically, in this embodiment, a circlip feeding mechanism 7 is further provided on the machine table 1. The circlip feeding mechanism 7 is arranged close to the first multi-axis displacement mechanism 6. The circlip feeding mechanism 7 is used to convey the circlip between the two first inverted U-shaped brackets 61. When the pressing cylinder 51 adjusts its position back and forth through the first multi-axis displacement mechanism 6 to be above the circlip feeding mechanism 7, it is convenient for the elastic telescopic shaft 55 on the base 52 to sleave the circlip, which helps to improve the convenience of automatic material taking. The conveying direction of the circlip feeding mechanism 7 is parallel to the conveying direction of the horizontal conveying mechanism 2, that is, the direction in which the circlip feeding mechanism 7 conveys the circlip is also from right to left, so as to convey the circlip to be installed to a position convenient for the elastic telescopic shaft 55 to sleave. It should be noted that the structure of the elastic telescopic shaft 55 is relatively conventional, and any suitable feeding mechanism composed of a conveyor belt assembly in the existing circlip feeding mechanism 7 can be used to achieve the conveyance of the circlip, and no specific limitation is made in this embodiment.

[0037] Further, at a position on the machine table 1 close to the horizontal conveying mechanism 2, such as the right side of the machine table 1, a second multi-axis displacement mechanism 8 and a detection platform 9 are provided. Two detection positioning holes are provided on the detection platform 9. A vision detection camera 10 is provided on the second multi-axis displacement mechanism 8. The vision detection camera 10 is used to perform quality inspection on the assembled product. By detecting whether the assembly is in place, it is possible to confirm whether the product is qualified, which is convenient for screening out unqualified products and qualified products. Among them, the second multi-axis displacement mechanism 8 drives the vision detection camera 10 to move in the X-axis direction or the Y-axis direction, so as to adjust the detection position of the vision detection camera 10. The vision detection camera 10 can move above the detection platform 9 under the drive of the second multi-axis displacement mechanism 8. During detection, just align the lens of the vision detection camera 10 with the product on the detection platform 9. In this embodiment, the vision detection camera 10 is, for example, a CCD (Charge-coupled Device) camera.

[0038] Specifically, the second multi-axis displacement mechanism 8 includes two relatively arranged second inverted U-shaped brackets 81. The two second inverted U-shaped brackets 81 are also spaced left and right. The bottom ends of the two second inverted U-shaped brackets 81 are also arranged on the machine table 1 along the front and back directions of the machine table 1. A second cross bar 82 is connected between the two second inverted U-shaped brackets 81. The two ends of the second cross bar 82 are correspondingly slid on the top rods of the two second inverted U-shaped brackets 81. The second cross bar 82 slides in the Y-axis direction; the vision detection camera 10 slides on the second cross bar 82, and the vision detection camera 10 slides in the X-axis direction.

[0039] Among them, third slide rails are correspondingly provided on the opposite side surfaces of the ejector rods of the two second inverted U-shaped brackets 81, and third sliders are slidably provided on both of the third slide rails. One of the third sliders is driven to slide by a third motor, and the third motor is arranged on the ejector rod of the second inverted U-shaped bracket 81 on the same side. Both ends of the second cross bar 82 are correspondingly connected to the two third sliders; a fourth slide rail is provided on the second cross bar 82, and a fourth slider driven to slide by a fourth motor is slidably provided on the fourth slide rail, and the vision inspection camera 10 is connected to the fourth slider.

[0040] Furthermore, a lifting cylinder is provided on the fourth slider, and the vision inspection camera 10 is arranged at the output end of the lifting cylinder. For the convenience of taking materials, a second magnetic attraction plate 11 is further provided at the output end of the lifting cylinder. The second magnetic attraction plate 11 is arranged close to the vision inspection camera 10, for example, the second magnetic attraction plate 11 is located at the rear side of the vision inspection camera 10. The magnetic attraction surface of the second magnetic attraction plate 11 also faces downward, and is used for sucking the assembled products to transfer them to the inspection platform 9 for inspection. It should be noted that before inspection, the assembled products need to be placed back on the carrier 3, and the carrier 3 is again transferred from left to right by the horizontal conveying mechanism 2 to a position corresponding to the vision inspection camera 10, so as to achieve the purpose of taking materials for inspection.

[0041] In this embodiment, openings penetrating up and down are provided at the central positions of the first magnetic attraction plate 54 and the second magnetic attraction plate 11, and a plurality of circular magnets are provided on the bottom surfaces of the first magnetic attraction plate 54 and the second magnetic attraction plate 11 on the outer periphery of the corresponding openings. The plurality of circular magnets are distributed in a circumferential array. The magnets are electromagnets. Correspondingly, magnetic attraction sheets are provided on the rotor and are magnetically adsorbed and cooperated with the electromagnets. There are also a plurality of magnetic attraction sheets, and the plurality of magnetic attraction sheets are also distributed in a circular array to correspond to the electromagnets one by one. When taking materials, the electromagnets are energized to have magnetism, and when discharging materials, the electromagnets are powered off to demagnetize.

[0042] It should be noted that, as Figure 9 shown in the layout structure, the liftable carrier 3 can be realized by a lifting mechanism, and the lifting mechanism is, for example, a mechanism composed of a lifting cylinder and the like to achieve the purpose of lifting drive. Figure 9 The structure shown in

[0043] is only an example and does not constitute a specific limitation. The horizontal conveying mechanism 2 is, for example, a mechanism composed of a carriage, a sliding block slidably arranged on the carriage, a driving motor and the like to achieve the purpose of horizontal conveying. The applications of the liftable carrier 3 and the horizontal conveying mechanism 2 are both prior arts. In actual applications, any suitable prior art can be referred to, and they will not be elaborated in this embodiment. It should be understood that for those ordinary skilled in the art, improvements or transformations can be made according to the above description, and all such improvements and transformations should fall within the protection scope of the appended claims of the present invention.
