[0040] The rotor carrier plate 34 is provided with a plurality of positioning grooves 341 which are evenly spaced along the length direction of the rotor carrier plate 34 and are adapted to the rotor 63. A through hole 342 for accommodating the shaft rod 65 is provided at the bottom of each positioning groove 341.

[0041] The carrier 33 is arranged at the rear end of the double-speed chain conveyor line 1, and the feed conveyor line 31 and the discharge conveyor line 32 are respectively arranged at the front and rear sides of the left end of the carrier 33, and the feed conveyor line 31 and the discharge conveyor line 32 are arranged in parallel, and side plates for limiting the rotor carrier plate 34 are fixedly installed on the frames of the feed conveyor line 31 and the discharge conveyor line 32; the feed conveyor line 31 is used to transfer the rotor carrier plate 34 to the carrier 33, and the discharge conveyor line 32 is used to move the rotor carrier plate 34 off the carrier 33;

[0043] A left limit plate 331 and a right limit plate 332 are fixedly installed on the left and right sides of the carrier 33, respectively. The left limit plate 331 is located between the side plates of the feed conveyor line 31 and the discharge conveyor line 32, and the distance between the left limit plate 331 and the right limit plate 332 is the same as the length of the rotor carrier 34; a front limit plate 333 is fixedly installed at the front end of the carrier 33, and a rear limit block 334 is fixedly installed at the rear end of the carrier 33, and the distance between the front limit plate 333 and the rear limit block 334 is equal to an integer multiple of the width of the rotor carrier 34; the left limit plate 331, the right limit plate 332, the front limit plate 333 and the rear limit block 334 cooperate to enclose a temporary storage area for storing the rotor carrier 34;

[0044] A rotor standardized feeding assembly 35 is arranged on the carrier 33, and the rotor standardized feeding assembly 35 includes a first pushing assembly arranged at the rear end of the carrier 33, and a second pushing assembly and a rotor positioning assembly arranged at the front end of the carrier 33. The first pushing assembly is used to push the rotor carrier plate 34 fed into the carrier 33 through the feed conveyor line 31 forward, and the second pushing assembly is used to push the rotor carrier plate 34 in the direction of the discharge conveyor line 32, so that the rotors 63 on the rotor carrier plate 34 are aligned with the clamping ends of the rotor transfer assembly 36 one by one; the rotor positioning assembly is used to support the rotor carrier plate 34 from the lower end of the carrier 33 to achieve accurate alignment of the rotor 63 on the rotor carrier plate 34 with the clamping end of the rotor transfer assembly 36;

[0045] The first pushing assembly includes a first pushing plate 351 and a pushing cylinder 352. The pushing cylinder 352 is fixedly mounted at the lower end of the carrier 33. The output end of the pushing cylinder 352 is fixedly mounted with the first pushing plate 351 through a connecting piece. A movable groove for avoiding the connecting piece is provided on the carrier 33. When the piston of the pushing cylinder 352 is fully extended, the front end surface of the pushing cylinder 352 is coplanar with the front end surface of the rear limit block 334, so that the pushing cylinder 352 can also assist in positioning the rotor carrier 34 when avoiding the inflow of the rotor carrier 34. The stroke of the piston of the pushing cylinder 352 is the same as the width of the rotor carrier 34, so that when the piston of the pushing cylinder 352 is contracted, the rotor carrier 34 in the temporary storage area can be pushed forward by a distance of the width of the rotor carrier 34.

[0046] The second pusher assembly includes a second push rod 353 and a linear module 354. The linear module 354 is fixedly mounted on the lower end of the carrier 33. The second push rod 353 is fixedly mounted on the movable end of the linear module 354 through a connecting piece. A movable groove for avoiding the connecting piece is provided on the carrier 33. The center distance between two adjacent positioning grooves 341 on the rotor carrier plate 34 is an interval. The linear module 354 drives the second push rod 353 to move to the left by an interval each time, so that the rotors 63 on the rotor carrier plate 34 are aligned with the clamping end of the rotor material moving assembly 36 one by one from left to right.

[0047] The rotor positioning assembly includes a positioning cylinder 355 and a positioning plug 356. The positioning cylinder 355 is fixedly installed at the lower end of the carrier 33. The output end of the positioning cylinder 355 is fixedly installed with a positioning plug 356 that cooperates with the through hole 342 of the rotor carrier plate 34; the top of the positioning plug 356 is provided with a guiding inclined surface, which can correct the offset of the rotor carrier plate 34 to a certain extent; when the rotor carrier plate 34 is completely located in the temporary storage area, the positioning plug 356 is aligned with the through hole 342 on the leftmost side of the rotor carrier plate 34; a sensor is provided on the top of the positioning plug 356. If the sensor detects that the positioning plug 356 does not smoothly push into the through hole 342 when moving up, an alarm is issued, indicating that the position of the rotor carrier plate 34 is offset;

[0048] The rotor material shifting assembly 36 includes a first linear module 361, a first X-axis moving plate 362, a first Z-axis cylinder 363 and a rotor shifting three-claw cylinder 364. The first linear module 361 is fixedly connected to the frame of the double-speed chain conveyor line 1 through a connecting piece and is erected on the upper side of the double-speed chain conveyor line 1. The first X-axis moving plate 362 is fixedly installed on the moving end of the first linear module 361. The first Z-axis moving plate 362 is fixedly installed on the first X-axis moving plate 363. The output end of the first Z-axis cylinder 363 is fixedly installed with a rotor shifting three-claw cylinder 364. The rotor shifting three-claw cylinder 364 realizes the transfer of the rotor 63 by clamping the shaft rod 65.

[0049] In the present application, a plurality of rotor carriers 34 are densely arranged along the X-axis direction in the temporary storage area. When the tooling plate 2 carrying the housing 61 and the stator 62 flows to the setting position, the rotor-shifting three-claw cylinder 364 clamps the leftmost rotor 63 on the frontmost rotor carrier 34 in the temporary storage area and installs it into the stator 62 on the tooling plate 2. Whenever the rotor-shifting three-claw cylinder 364 removes a rotor 63 from the rotor carrier 34, the linear module 354 pushes the rotor carrier 34 to the left by a spacing distance through the second push rod 353, so that the next rotor 63 on the rotor carrier 34 is in a position to wait for the rotor-shifting three-claw cylinder 364 to clamp it, and the positioning cylinder 355 drives the rotor carrier 34 to move to the left. The dynamic positioning pin 356 moves vertically upward and is inserted into the through hole 342 on the lower side of the rotor 63 to achieve precise positioning of the rotor 63; when all the rotors 63 in the rotor carrier 34 are removed, most of the parts of the rotor 63 are already located on the discharge conveyor line 32, and the rotor carrier 34 is controlled by the discharge conveyor line 32 to flow out from the carrier 33, and a new rotor carrier 34 fully loaded with rotors 63 is moved into the temporary storage area through the feed conveyor line 31, and then the pushing cylinder 352 controls the first pushing plate 351 to push the rotor carrier 34 in the temporary storage area forward, so that the rotor carrier 34 originally at the front end in the temporary storage area fits with the front limit plate 333, and the loading process of the rotor 63 is repeated.

[0050] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit the same. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that the technical solutions described in the aforementioned embodiments may still be modified, or some of the technical features may be replaced by equivalents. Such modifications or replacements will not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of the present invention.
