[0002] A motor generally consists of components such as a rotor, a stator assembly, and a housing. Among them, the stator assembly includes a stator core, an insulating skeleton, and a winding. The stator core is usually composed of a plurality of core blocks distributed in an annular array. The core blocks are T-shaped core blocks. The winding is wound around the insulating skeleton. The winding is usually an enameled wire and is wound around the insulating skeleton. As the main part for supporting and insulating the stator winding of the motor, the insulating skeleton is usually assembled on the core blocks by plugging, so that the insulating skeleton covers the core blocks of the stator core. In the existing stator assembly process, since the number of core blocks on the stator core is large and the core blocks are arranged in a ring shape, during the process of successively pressing a plurality of insulating skeletons onto the core blocks on the stator core, it is necessary to frequently perform operations such as aligning the insulating skeleton and the core block, adjusting the position of the stator core, and assembling the insulating skeleton and the core block. Each operation still requires manual intervention, which not only affects the assembly efficiency of the stator, but also increases the labor intensity and labor cost of workers.

The assembly propulsion mechanism 514 is a telescopic cylinder, and the propulsion end of the assembly propulsion mechanism 514 translates in the Y-axis direction. On the top of the second support frame 13, a stator detection device 17 for detecting whether the stator core 241 is located at the stator assembly station is also arranged. The stator detection device 17 is a reflective photoelectric switch, which is a prior art and will not be described in detail here.

[0042] The skeleton assembly assembly 52 includes a flipping mounting frame 521, a flipping mechanism 522 and a flipping platform 523. The flipping mounting frame 521 is fixedly connected to the frame 2. The flipping mechanism 522 is arranged on the flipping mounting frame 521. The flipping platform 523 is arranged at the flipping end of the flipping mechanism 522. The flipping mechanism 522 is a flipping cylinder. The flipping platform 523 extends along the translation direction of the stator assembly station 513. At the position of the top of the skeleton travel frame 61 relative to the flipping platform 523, a downward extending flipping centering frame 18 is arranged. The flipping centering frame 18 is pivotally arranged between the side of the flipping platform 523 away from the flipping mechanism 522.

[0043] On the flipping platform 523, a plurality of skeleton pressing stations 19 are telescopically arranged and distributed in an array along its length direction. Each skeleton loading station 2101 corresponds to each skeleton pressing station 19 respectively.

The skeleton placement fixture 191 extends to the outside of the movable hole 1903 for the insulating skeleton 242 to be positioned and sleeved. By using the sliding connection between the guide columns 194 and the guide holes 501, the skeleton press-fitting station 19 is guided to perform telescopic activities relative to the flipping platform 523, so that the placement plate 192 drives the insulating skeleton 242 to eject and separate from the skeleton placement fixture 191.

[0045] Reference Figure 7 , Figure 11 , both the skeleton placement fixture 191 and the skeleton feeding station 2101 are provided with elastic positioning pins 23.

[0050] The finished product detection device 92 is used to detect whether the stator assembly 24 is positioned and placed on the finished product loading position 2201. The finished product detection device 92 is a reflective photoelectric switch, which is prior art and will not be elaborated here in detail.

The finished product transfer device 8 includes a finished product travel frame 81, a finished product two-dimensional material transfer mechanism 82, and a finished product clamping mechanism 83. The finished product travel frame 81 is fixedly connected to the machine frame 2 and is located above the finished product feeding device 9. The finished product two-dimensional material transfer mechanism 82 is arranged on the finished product travel frame 81. The finished product two-dimensional material transfer mechanism 82 is an XZ moving platform, which mainly includes an X-direction translation mechanism and a Z-direction translation mechanism. The translation end of the X-direction translation mechanism is connected to the Z-direction translation mechanism. The translation end of the Z-direction translation mechanism is the material transfer end of the finished product two-dimensional material transfer mechanism 82. The XZ moving platform is prior art and will not be elaborated here in detail. The finished product clamping mechanism 83 is arranged on the material transfer end of the finished product two-dimensional material transfer mechanism 82. The finished product clamping mechanism 83 is used to clamp the stator assembly 24. The finished product clamping mechanism 83 is a clamping cylinder. Driven by the finished product two-dimensional material transfer mechanism 82, the finished product clamping mechanism 83 reciprocates between the assembly device 5 and the finished product feeding device 9 to load the stator assembly 24 at the finished product feeding device 9.

[0052] Reference Figures 1 to 12When the automatic assembly machine is in use, the stator tray fixture 20 loaded with a plurality of stator cores 241 is placed on the stator feeding table 1. When the stator tray fixture 20 moves from the stator feeding table 1 to the stator feeding device 3, it is positioned and placed for the stator transfer device 4 to perform the transfer operation. The skeleton tray fixture 21 loaded with a plurality of insulating skeletons 242 is placed on the working surface of the skeleton conveyor belt 71. When the skeleton tray fixture 21 moves to the position corresponding to the assembly device 5, the lifting end of the skeleton feeding lifting mechanism 72 lifts the skeleton tray fixture 21 to separate it from the skeleton conveyor belt 71, so that the skeleton transfer device 6 can perform the transfer operation of each insulating skeleton 242.

[0053] Driven by the flipping mechanism 522, the flipping platform 523 switches to a horizontal position or a vertical position; When the flipping platform 523 is misaligned with the travel space 504, the flipping mechanism 522 drives the flipping platform 523 to switch to a horizontal position, with the operating surface 1902 facing downward and the placement surface 1901 facing upward. The skeleton transfer device 6 positions each insulating skeleton 242 on the placement surface 1901 of each skeleton pressing station 19, and the stator transfer device 4 positions the stator core 241 on the stator assembly station 513.

[0054] Afterwards, the flipping mechanism 522 drives the flipping platform 523 to switch to the vertical position. The design of the elastic positioning pins 23 on the frame placement fixture 191 prevents the insulating frame 242 from escaping from the frame pressing station 19 during the flipping process of the flipping platform 523. Driven by the assembly translation mechanism 511, the stator assembly station 513 moves to the side of the flipping platform 523 so that the flipping platform 523 in the vertical position enters the travel space 504 until the skeleton pressing station 19 close to the flipping mechanism 522 corresponds to the assembly propulsion mechanism 514, and the stator assembly station 513 is driven to rotate to the required position by the rotating mechanism 512, so that the core block 2401 of the stator core 241 corresponds to the propulsion end of the assembly propulsion mechanism 514, and the height position of the lifting platform 15 is adjusted in the Z-axis direction through the two lifting adjustment mechanisms 14, thereby adjusting the height position of the stator core 241, ensuring that the insulating skeleton 242 corresponds to the corresponding core block 2401, realizing automatic alignment of the core block 2401 and the insulating skeleton 242, and ensuring the corresponding core block 2401 and the insulating skeleton 242 are accurately assembled.

[0055] Then, the operating surface 1902 of the skeleton pressing station 19 faces the assembly pushing mechanism 514, and the placement surface 1901 of the skeleton pressing station 19 faces the stator assembly station 513, so that the assembly pushing mechanism 514 can push the corresponding skeleton pressing station 19 to overcome the elastic member 1904 and translate along the Y-axis direction. The placement plate 192 drives the insulating skeleton 242 to separate from the skeleton placement fixture 191 and press the insulating skeleton 242 onto the corresponding iron core block 2401. At this time, the inner side wall of the operating plate 193 abuts against the limiting plate 503 to limit the operating plate 193, thereby ensuring the consistency of the translation stroke of each skeleton pressing station 19.

[0056] After the insulating frame 242 and the corresponding iron core block 2401 are assembled, the assembly translation mechanism 511 drives the stator assembly station 513 to translate along the X-axis direction, so that the flip platform 523 in the vertical position is within the travel space 504 and the flip platform 523 and the stator assembly station 513 are separated from each other. The stator core 241 on the stator assembly station 513 passes through each frame pressing station 19 in turn. In this process, the rotating mechanism 512 drives the stator assembly station 513 to rotate. The stator core 241 is driven to rotate, so that the core block 2401 that has not yet been pressed with the insulating frame 242 corresponds to the next frame pressing station 19, and the assembly pushing mechanism 514 performs the pressing operation between the insulating frame 242 and the core block 2401, and the cycle is repeated in sequence to complete the assembly operation of the stator assembly 24. After completing the assembly of the stator core 241 and each insulating frame 242, the assembly device 5 is reset to prepare for the next assembly of the stator core 241 and each insulating frame 242.

[0057] After the stator assembly 24 is assembled, the assembly translation mechanism 511 moves the stator assembly 24 to the side of the finished product transfer device 8. The finished product transfer device 8 takes the stator assembly 24 out of the assembly table 10 and loads it to the finished product loading position 2201. The finished product conveyor belt 91 moves the finished product loading position 2201 out for finished product unloading.

[0058] The automatic assembly machine has a high degree of automation, improves the assembly efficiency of the stator assembly 24, reduces the labor intensity of workers, ensures the quality and consistency of the product, and is conducive to mass production.

[0059] Of course, the above are only typical examples of the present invention. In addition, the present invention may also have many other specific implementations. All technical solutions formed by equivalent replacement or equivalent transformation fall within the scope of protection required by the present invention.
