Specific implementation manner

[0043] Example:

[0044] Please refer to Figures 1-14 , this embodiment is an automatic stator-rotor assembly mechanism 100, which includes a stator clamping device 2 that grabs the stator from the stator feeding station to a stator transfer device 1, a waveform gasket clamping device 4 that grabs the waveform gasket from a waveform gasket supply unit 3 to the stator on the stator transfer device 1, a stator assembly clamping device 6 that grabs the stator with the waveform gasket installed from the stator transfer device 1 to a stator-rotor pressing device 5, a rotor clamping device 7 that grabs the rotor from the rotor loading station to a rotor receiving station, and a rotor adjustment and transfer device 8 that receives the rotor on the rotor clamping device 7, rotates and adjusts it, and then transports it to the stator-rotor pressing device 5.

[0045] The corrugated gasket supply unit 3 includes a vibrating bowl 31, a first clamping unit 33 for taking out the corrugated gaskets from the output end of the vibrating bowl 31 and placing them in a first gasket carrier 32, a first driving member 34 for driving the first gasket carrier 32 to move horizontally in a straight line, a gasket knocking unit 35 located on the moving path of the first gasket carrier 32 for knocking the gaskets in the first gasket carrier 32, and a gasket picking detection unit 36 for detecting whether there is any missing or excessive picking of the taken-out gaskets. The corrugated gasket clamping device 4 grabs the gaskets from the gasket knocking unit 35 into the gasket picking detection unit 36, and then grabs them from the gasket picking detection unit 36 onto the stator transfer device 1.

[0046] The first clamping unit 33 and the corrugated gasket clamping device 4 have the same structural principle and both include a second driving member 41, a first movable plate 42 driven by the second driving member 41 to move horizontally in a straight line, a first air cylinder 43 fixed on the first movable plate 42, a second movable plate 44 driven by the first air cylinder 43 to move up and down, a pneumatic gripper air cylinder 45 fixed on the second movable plate 44, and a gasket support clip 46 driven by the pneumatic gripper air cylinder 45 to open or close. The gasket support clip 46 is inserted into the central hole of the gasket, and then the pneumatic gripper air cylinder 45 drives the gasket support clip 46 to expand outwards to support the corrugated gasket, realizing clamping.

[0047] The gasket knocking unit 35 includes a second air cylinder 351 and a knocking ingot 352 driven by the second air cylinder 351 to move up and down and inserted into the first gasket carrier 32 to knock the gaskets. In this embodiment, by setting the gasket knocking unit 35 to knock the gaskets a set number of times, an elastic deformation amount is generated in the corrugated gaskets, so that they have elastic pressure.

[0048] The gasket material taking and detecting unit 36 includes a second gasket bearing seat 361, a displacement sensor 362 located beside the second gasket bearing seat 361, a third air cylinder 363, a third movable plate 364 driven by the third air cylinder 363 to perform horizontal linear motion, a fourth air cylinder 365 fixed on the third movable plate 364, a fourth movable plate 366 driven by the fourth air cylinder 365 to perform up and down motion, a gasket contact head 367 fixed on the fourth movable plate 366, and a pressing head 368 pressing the sensing head of the displacement sensor 362. A buffer column 369 for buffering the downward movement of the fourth movable plate 366 is also arranged beside the second gasket bearing seat 361. The gasket contact head 367 extends into the second gasket bearing seat 361 and presses against the surface of the gasket. Synchronously, the pressing head 368 moves downward and presses against the displacement sensor 362. When the gasket contact head 367 touches the surface of the gasket, it cannot continue to descend by a large distance. At this time, by reading the data of the displacement sensor 362, the thickness of the gasket in the second gasket bearing seat 361 can be measured. According to the thickness of the gasket, it can be judged whether multiple gaskets are taken or no gasket is taken. Thus, it is ensured that there is exactly one gasket clamped by the corrugated gasket clamping device 4.

[0049] The stator clamping device 2 mainly grabs the stator from a stator feeding station to a stator loading station. It includes a fifth air cylinder 21, a fifth movable plate 22 driven by the fifth air cylinder 21 to perform horizontal linear motion, a third driving member 23 fixed on the fifth movable plate 22, a sixth movable plate 24 driven by the third driving member 23 to perform up and down motion, a sixth air cylinder 25 fixed on the sixth movable plate 24, and stator clamping jaws 26 driven by the sixth air cylinder 25 to open or close.

[0050] The stator transfer device 1 includes a fourth driving member 11 and a carrying tooling 12 driven by the fourth driving member 11 to perform horizontal linear motion. The stator transfer device 1 drives the carrying tooling 12 to switch positions among three positions: the discharging position of the stator clamping device 2 (i.e., the above-mentioned stator loading station), the corrugated gasket loading station, and the stator assembly taking-away station. A limiting groove for carrying the stator is arranged on the carrying tooling 12. A first vision detection unit 13 for detecting whether the corrugated gasket is correctly placed into the stator is arranged on the moving path of the carrying tooling 12.

[0051] The stator assembly clamping device 6 includes a fifth driving member 61, a seventh movable plate 62 driven by the fifth driving member 61 to perform horizontal linear motion, a seventh air cylinder 63 fixed on the seventh movable plate 62, an eighth movable plate 64 driven by the seventh air cylinder 63 to move perpendicular to the moving direction of the seventh movable plate 62, and two clamping units 65 fixed on the eighth movable plate 64. One of the two clamping units 65 is used to grasp the stator with gaskets installed into the stator-rotor pressing device 5, and the other is used to take out the stator-rotor assembly from the stator-rotor pressing device 5 to the blanking station. The clamping unit 65 includes an eighth air cylinder 651, an eighth movable plate 652 driven by the eighth air cylinder 651 to perform up and down motion, a pneumatic gripper cylinder 653 fixed on the eighth movable plate 652, and a gripper 654 driven by the pneumatic gripper cylinder 653 to perform opening or clamping actions.

[0052] The rotor clamping device 7 includes a sixth driving member 71, a ninth movable plate 72 driven by the sixth driving member 71 to perform horizontal linear motion, a ninth air cylinder 73 fixed on the ninth movable plate 72, a tenth movable plate 74 driven by the ninth air cylinder 73 to perform up and down motion, a pneumatic gripper cylinder 75 fixed on the tenth movable plate 74, and a gripper 76 driven by the pneumatic gripper cylinder 5 to perform opening or clamping actions. A scanning gun 77 is arranged on the horizontal movement path of the gripper 76 to detect whether the incoming rotor meets the requirements.

[0053] The rotor adjustment and transfer device 8 includes a seventh driving member 81, an eleventh movable plate 82 driven by the seventh driving member 81 to perform horizontal linear motion, an eighth driving member 83 fixed on the eleventh movable plate 82, a positioning support seat 84 driven by the eighth driving member 83 to perform rotational motion, and a second vision detection unit 85 for photographing and positioning the rotor in the positioning support seat 84. The position image of the rotor in the positioning support seat 84 is obtained through the second vision detection unit 85, and the angle that the rotor needs to rotate is automatically calculated in the host computer software program. Then, the eighth driving member 83 rotates the rotor to the set angle position according to the instruction to achieve the angle position adjustment. The positioning support seat 84 includes a positioning groove 841 for carrying the rotor and an elastic clamping block 842 that abuts against and presses the outer peripheral surface of the rotor to keep its position fixed in the positioning groove 841. The position of the rotor in the positioning groove 841 is fixed by the elastic clamping block 842, effectively preventing deviation during the rotation adjustment of the rotor angle position, resulting in inaccurate angle adjustment.

[0054] The stator-rotor pressing device 5 includes a support base 51 for carrying the stator, a pressing plate 52 located above the support base 51, a ninth driving member 53 for driving the pressing plate 52 to move up and down, a twelfth movable plate 54 fixed to the movable end of the ninth driving member 53, a thirteenth movable plate 56 that is suspended on the twelfth movable plate 54 and can float up and down through a bracket 55, and a shaft clamping unit 57 fixed to the bracket 55 and clamping the output shaft of the rotor. The shaft clamping unit 57 includes a tenth cylinder 571, a clamping driving sleeve 572 driven by the tenth cylinder 571 to move up and down, and a shaft clamping jaw 573 that passes through the clamping driving sleeve 572 and cooperates with it through an inclined surface to realize the opening and closing clamping actions. The upper end of the shaft clamping jaw 573 is fixedly connected to the lower surface of the thirteenth movable plate 56. On both sides of the support base 51, a pair of stator pressing units 58 are also provided. The stator pressing unit 58 includes an eleventh cylinder 581 and a pressing rod 582 driven by the eleventh cylinder 581 to move up and down and rotate horizontally. An avoidance opening for avoiding the position of the pressing rod 582 is provided on the pressing plate 52.

[0055] This embodiment further includes a blanking transfer device 9 for realizing the blanking and output of products. The blanking transfer device 9 includes a twelfth cylinder 91 and a product carrying tooling 92 driven by the twelfth cylinder 91 to move horizontally in a straight line. The product carrying tooling 92 is driven by the twelfth cylinder 91 to switch positions between the blanking station and the product output station.

[0056] The stator and the gasket are fed from both sides of the stator transfer device 1, and then are respectively grabbed by the stator clamping device 1, the first clamping unit 33, and the corrugated gasket clamping device 4 and sent into the stator transfer device 1.

[0057] The stator-rotor pressing device 5 is arranged at the end position of the stator transfer device 1. The blanking transfer device 9 is located beside the downstream of the stator-rotor pressing device 5 along the product movement direction in the stator transfer device 1. The stator assembly clamping device 6 grabs the stator with the gasket from the stator transfer device 1 and places it on the stator-rotor pressing device 5, and at the same time grabs the pressed stator-rotor assembly in the stator-rotor pressing device 5 and outputs it onto the blanking transfer device 9.

[0058] The stator assembly clamping device 6 and the rotor adjustment transfer device 8 are respectively arranged on opposite sides of the stator-rotor pressing device 5, and feed the stator and the rotor into the stator-rotor pressing device 5 from both sides.

[0059] The working principle of the stator-rotor automatic assembly mechanism 100 in this embodiment is as follows:

[0060] 1) Stator feeding: The stator clamping device 2 grabs the stator and moves it from the stator feeding station to the stator loading station, and places it into the carrying tooling 12 in the stator transfer device 1 (at this time, the carrying tooling 12 has already been located at the stator loading station);

[0061] 2) The loading fixture 12 loads and moves the stator to the waveform gasket loading station;

[0062] 3) Waveform gasket feeding: The waveform gaskets are output one by one from the vibrating bowl 31, and then grasped by the first clamping unit 33 and placed into the first gasket carrier 32. Driven by the first driving member 34, it moves to the lower part of the gasket knocking unit 35, and then the second cylinder 351 drives the knocking ingot 352 to knock the gasket for a set number of times; then the waveform gasket clamping device 4 takes out the knocked waveform gasket from the first gasket carrier 32 and places it into the second gasket carrier 361 in the gasket picking and detecting unit 36. The thickness of the gasket is detected by the gasket contact head 367 and the pressing head 368 to determine whether there is a phenomenon of missing or over-picking of gaskets; then the waveform gasket clamping device 4 takes out the waveform gasket from the second gasket carrier 361 and moves it to the waveform gasket loading station;

[0063] 4) Waveform gasket loading: The waveform gasket clamping device 4 grasps the waveform gasket and loads it into the stator, and the first vision detection unit 13 detects its position to determine whether the waveform gasket is placed accurately;

[0064] 5) The loading fixture 12 loads the stator assembly with gaskets and moves it to the stator assembly taking-away station;

[0065] 6) The stator assembly clamping device 6 grasps the stator assembly at the stator assembly taking-away station and places it on the support base 51 of the stator-rotor pressing device 5. The eleventh cylinder 581 in the stator pressing unit 58 is activated, driving the pressing rod 582 to rotate horizontally by 90° and simultaneously pressing down the upper surface of the circumferential plate surface of the stator assembly, pressing down the stator assembly;

[0066] 7) Rotor feeding: The rotor clamping device 7 clamps a rotor from the rotor feeding station to the rotor adjusting and transferring device 8. During this process, the information of the rotor incoming material is traced by scanning with the scanning gun 77 to check whether it meets the requirements; the rotor is placed on the positioning support seat 84 and moves to the position of the second vision detection unit 85 under the drive of the seventh driving member 81 for position photographing. Then, according to the photographing result, the eighth driving member 83 drives the rotor to rotate a certain angle to reach the set angular position state to complete the angle adjustment; the seventh driving member 81 continues to drive the rotor to move into the stator-rotor pressing device 5;

[0067] 8) Stator-rotor assembly pressing: After the rotor moves to the lower part of the pressing plate 52, the ninth driving member 53 drives the twelfth movable plate 54 to descend, and the thirteenth movable plate 56, the pressing plate 52, and the shaft clamping unit 57 descend synchronously. During this process, when the pressing plate 52 abuts against the upper surface of the rotor, the tenth cylinder 571 in the shaft clamping unit 57 is activated to drive the shaft clamping claws 573 to clamp the rotating shaft of the rotor, and then retreat upward; the positioning support seat 84 exits the stator-rotor pressing device 5; the ninth driving member 53 drives the twelfth movable plate 54 to descend, and the rotor descends synchronously and then is placed inside the stator. Since the pressing plate 52 and the shaft clamping claws 573 are fixed on the thirteenth movable plate 56, and the thirteenth movable plate 56 is hung on the twelfth movable plate 54 in a vertically floating manner through a bracket 55, when the twelfth movable plate 54 continues to descend, the positions of the pressing plate 52 and the rotor remain unchanged, so that the rotor is not in rigid contact when placed inside the stator, effectively avoiding hard collisions and damage during the assembly of the stator and rotor; when the twelfth movable plate 54 continues to descend until the twelfth movable plate 54 and the thirteenth movable plate 56 are in a rigid pressure transmission state, the pressing force is applied to the pressing plate 52, and the pressing plate 52 presses the rotor into the positioning assembly. Then, the shaft clamping claws 573 release the clamping of the rotating shaft of the rotor, and the thirteenth movable plate 56 moves upward to retreat; the pressing rod 582 rotates upward to retreat;

[0068] 8) Stator-rotor assembly discharging: Another clamping unit 65 in the stator assembly clamping device 6 grabs the stator-rotor assembly and outputs it to the discharging transfer device 9, completing the automatic assembly operation of the stator and the rotor.

[0069] The beneficial effects of the stator-rotor automatic assembly mechanism 100 in this embodiment are as follows: It realizes a series of fully automated operations such as automatic detection and feeding of the rotor, automatic adjustment of the rotor angle, automatic feeding of the stator, automatic supply and tapping of the wave washer, in-process inspection and automatic feeding, and automatic pressing and assembly of the stator and rotor, greatly improving the assembly efficiency and quality of the stator and rotor; and the overall structural layout is compact, occupying little space.

[0070] The above are only some embodiments of the present invention. For those of ordinary skill in the art, without departing from the inventive concept of the present invention, several modifications and improvements can still be made, and these all belong to the protection scope of the present invention.
