[0027] In order to make the purpose, technical solution and advantages of the embodiments of the utility model clearer, the following will be described clearly and completely in combination with the technical solution in the embodiments of the utility model. Obviously, the described embodiments are partial embodiments of the utility model, not all embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the protection scope of the utility model.

[0028] The utility model is implemented as follows Figures 1 to 6 As shown in the figure, a stator-rotor assembly mechanism includes a pressing cylinder 1, a base 2, an elastic reset member 3, a magnetic plate 4 and an elastic telescopic shaft 5; the base 2 is arranged at the output end of the pressing cylinder 1, the magnetic plate 4 is located below the base 2, the magnetic plate 4 and the base 2 are connected by the elastic reset member 3, the fixed end of the elastic telescopic shaft 5 is arranged on the base 2, and the telescopic end of the elastic telescopic shaft 5 passes through the magnetic plate 4 to take the retaining spring; the magnetic surface of the magnetic plate 4 faces downward to absorb the rotor, and after the elastic telescopic shaft 5 and the magnetic plate 4 obtain the retaining spring and the rotor in turn, the pressing cylinder 1 drives the base 2 to press down to complete the assembly.

[0029] Specifically, in this embodiment, the base 2 is a rectangular frame, which is formed by a vertical plate 21 and four enclosures 22, wherein a lower enclosure is arranged at the lower edge of the vertical plate 21, wherein the left and right enclosures are arranged at the left and right edges of the vertical plate 21, wherein the upper enclosure is arranged at the upper ends of the left and right enclosures, thereby forming a accommodating space enclosed by a vertical plate 21 and four enclosures 22. The fixed end of the elastic telescopic shaft 5 is arranged at the middle of the upper surface of the lower enclosure of the base 2, that is, located in the accommodating space. The telescopic end of the elastic telescopic shaft 5 passes through the lower enclosure and the magnetic suction plate 4 of the base 2 in turn, and the bottom of the telescopic end of the elastic telescopic shaft 5 is located below the magnetic suction plate 4.

[0030] Among them, the magnetic attraction plate 4 includes a plate body 41. A through hole 401 is formed in the middle of the plate body 41. The telescopic end of the elastic telescopic shaft 5 passes through the through hole 401. The outer diameter of the telescopic end of the elastic telescopic shaft 5 is smaller than the inner diameter of the through hole 401, so that the telescopic end of the elastic telescopic shaft 5 can smoothly move up and down in the through hole 401. Moreover, the inner diameter of the through hole 401 is smaller than the outer diameter of the snap ring, so that when the telescopic end of the elastic telescopic shaft 5 removes the snap ring, the snap ring is restricted by the magnetic attraction plate 4 and will not pass through the through hole 401. The bottom of the telescopic end of the elastic telescopic shaft 5 is in a shape of converging inward, which is convenient for snapping into the snap ring so that the snap ring can be smoothly sleeved on it. A plurality of magnet blocks 42 are provided on the lower surface of the plate body 41 near the outer peripheral edge of the through hole 401. The plurality of magnet blocks 42 are distributed in a circular array; correspondingly, a receiving groove is formed in the lower surface of the plate body 41 at a position corresponding to each magnet block 42. Each magnet block 42 is arranged in the corresponding receiving groove, and the lower surface of each magnet block 42 and the lower surface of the plate body 41 are both located on the same horizontal plane, that is, the depth of the receiving groove is adapted to the thickness of the magnet block 42, so as to improve the magnetic attraction stability when sucking the rotor. The magnet block 42 is an electromagnet.

[0031] It can be understood that a magnetic attraction sheet magnetically attracted and cooperated with the electromagnet should be provided on the rotor. 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 electromagnet is energized and has magnetism. When discharging materials, the electromagnet is powered off and demagnetized.

[0032] Specifically, in this embodiment, there are two elastic reset members 3, and the two elastic reset members 3 are correspondingly located on both sides of the telescopic end of the elastic telescopic shaft 5 to provide a stable elastic force. Among them, the elastic reset member 3 is a spring. Two telescopic guide posts 6 are also provided on the base 2. The fixed ends of the two telescopic guide posts 6 are arranged on the upper side surface of the lower surrounding plate of the base 2, that is, they are also located in the accommodation space. The fixed ends of the two telescopic guide posts 6 are correspondingly located on both sides of the fixed end of the elastic telescopic shaft 5. The telescopic ends of the two telescopic guide posts 6 correspondingly pass through the lower surrounding plate of the base 2 and the inside of the elastic reset member 3 and are connected to the magnetic attraction plate 4. The application function of the telescopic guide post 6 is the same as that of the spring. A pressure sensor is arranged inside the fixed end of the elastic telescopic shaft 5. The pressure sensor can be specifically arranged at any suitable position inside the fixed end of the elastic telescopic shaft 5, and is used to sense the pressure value during telescopic contact, so as to facilitate confirming whether the position movement is in place.

[0033] During operation, first, the retaining ring is sleeved on the telescopic end of the elastic telescopic shaft 5. During the sleeving process, the retaining ring will be gradually expanded by a certain size until it is sleeved on the telescopic end of the elastic telescopic shaft 5. Then, the rotor is attracted by the magnetic attraction plate 4, and the pressing cylinder 1 is controlled to drive the base 2 to press down, so that the rotor and the stator are pressed together, and the retaining ring is pressed tightly on the rotor. Then, the pressing cylinder 1 is controlled to drive the base 2 to move upward. During this process, the telescopic end of the elastic telescopic shaft 5 moves upward first. Restricted by the magnetic attraction plate 4, the retaining ring gradually disengages from the elastic telescopic shaft 5 and is sleeved on the rotor. Among them, the rotor can be adsorbed on the magnetic attraction plate 4 by means of manual feeding.

[0034] Further, in actual application, a multi-axis displacement mechanism 7 is used in cooperation with the stator-rotor assembling mechanism of the embodiment of the present utility model. The stator-rotor assembling mechanism is arranged on the multi-axis displacement mechanism 7, and the position of the stator-rotor assembling mechanism is adjusted through the multi-axis displacement mechanism 7, so as to meet the realization of related operations such as automatic material taking.

[0035] Among them, the multi-axis displacement mechanism 7 includes two oppositely arranged inverted U-shaped brackets 71. The two inverted U-shaped brackets 71 are arranged at left and right intervals. A cross bar 72 is connected between the top rods of the two inverted U-shaped brackets 71. The two ends of the cross bar 72 are slidably arranged on the top rods of the two inverted U-shaped brackets 71 respectively. The cross bar 72 slides in the Y-axis direction, and the Y-axis direction is, for example, the front-back horizontal direction; the pressing cylinder 1 slides on the cross bar 72, and the pressing cylinder 1 slides in the X-axis direction, and the X-axis direction is, for example, the left-right horizontal direction.

[0036] Specifically, first slide rails are correspondingly arranged on the opposite side surfaces of the top rods of the two inverted U-shaped brackets 71. First sliders are slidably arranged on both of the 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 inverted U-shaped bracket 71 on the same side. The two ends of the cross bar 72 are correspondingly connected to the two first sliders; a second slide rail is arranged on the cross bar 72, and a second slider driven to slide by a second motor is slidably arranged on the second slide rail. The fixed end of the pressing cylinder 1 is connected to the second slider.

[0037] The stator-rotor assembling mechanism of the embodiment of the present utility model integrates the structures for assembling the stator and rotor and fixing the retaining ring, so that the operations of assembling the stator and rotor and fixing the retaining ring can be completed in one process, which is helpful for the batch processing and production of motors and effectively improves the production efficiency.
