The traditional approach is to first assemble the motor: press the motor rotor into the housing with the stator core, and then press the inner and outer rotors of the oil pump with the motor housing. This requires two sets of equipment, occupies two workstations on two production lines, is inefficient, and makes it difficult to ensure product consistency. There is a need for an inner and outer rotor assembly machine and assembly method that can effectively improve efficiency and product quality. Summary of the Invention

The material transfer assembly includes a press-fitting fixture and a lateral movement unit that drives the press-fitting fixture laterally. The running trajectory of the press-fitting fixture includes a press-fitting position directly below the press-fitting machine and a feeding position away from the press-fitting position. The press-fitting fixture includes a floating fixture base and a base plate arranged vertically. The base plate is connected to the movable end of the lateral movement unit, and a floating connection is provided on the base plate. The floating unit of the lifting fixture base has a positioning groove for positioning the motor housing. The bottom of the positioning groove has a positioning pin for positioning the inner and outer rotors. The lower end of the positioning pin passes through the lower end of the floating fixture base. The lower end of the floating fixture base is connected to a floating cylinder that drives the positioning pin to rise and fall.

The two grippers of the clamping cylinder are arranged longitudinally, and each gripper is fixed with a lifting cylinder. The movable end of the lifting cylinder is provided with a transverse support plate corresponding to the slot. After the pressing machine completes the pressing, the transverse unit moves the pressing fixture to the unloading position, with the two support plates facing the two slots. Then, the floating cylinder drives the positioning pin to rise and lift the pressed product. When the lower end of the product exceeds the height of the support plate, the machine stops. The clamping cylinder drives the two support plates to clamp the product, and the two lifting cylinders drive the two support plates to rise, causing the product to detach from the positioning seat.

The material transfer assembly 3 includes a press fixture 30 and a transverse transfer unit 31 for moving the press fixture laterally. The running trajectory of the press fixture 30 includes a press position directly below the press machine 1 and a feeding position away from the press position. The press fixture 30 includes a floating fixture base and a base plate 310 arranged vertically. The base plate 310 is connected to the movable end of the transverse transfer unit 31, and a floating connection floating fixture is provided on the base plate 310. The floating unit 320 of the seat has a positioning groove for positioning the motor housing on the floating fixture seat. The bottom of the positioning groove is provided with a positioning pin 301 for positioning the inner and outer rotors. The lower end of the positioning pin 301 passes through the lower end of the floating fixture seat. The lower end of the floating fixture seat is connected to a floating cylinder 302 that drives the positioning pin 301 to rise and fall. The processing table is also provided with a first loading robot 7 that moves the motor housing and motor rotor on the loading conveyor belt to the pressing fixture located at the loading position, and a second loading robot 8 that moves the inner and outer rotors supplied by the inner and outer rotor loading assembly to the vision recognition assembly for visual recognition, adjusts the angle of the inner and outer rotors after visual recognition, and loads them to the pressing fixture located at the loading position.

[0029] The transverse unit 31 drives the pressing fixture 30 to the loading position. The second loading robot 8 moves the inner and outer rotors supplied by the inner and outer rotor loading assembly 4 (existing loading components can be used, no modification is needed, and it will not affect the implementation of this application) to the vision recognition assembly 5 for visual recognition. The second loading robot 8 adjusts the angle of the visually recognized inner and outer rotors and loads them onto the pressing fixture 30. The positioning pin 301 passes through the inner hole of the inner and outer rotors to position them. The first loading robot 7 loads the motor housing from the loading conveyor belt onto the pressing fixture 30. The motor housing is fitted outside the inner and outer rotors and is positioned with the assistance of the positioning groove. Floating cylinder 3 02 drives the positioning pin 301 to descend to the first height, and the positioning pin 301 partially exits the inner hole of the inner and outer rotors; the first loading robot 7 loads the motor rotor on the loading conveyor belt 2 into the motor housing on the pressing fixture 30, and the lower end of the shaft of the motor rotor passes through the inner hole of the inner and outer rotors for positioning; the transverse unit 31 drives the pressing fixture 30 to move to the pressing position located directly below the pressing machine 1, and the pressing machine 1 applies pressure to the motor rotor for one-time pressing. During the pressing process, the floating cylinder 302 drives the positioning pin 301 to gradually descend to the second height in cooperation with the moving end of the pressing machine 1 until the positioning pin completely exits the inner hole of the inner and outer rotors. After pressing, the finished product is removed by the unloading robot 6.

[0030] By applying the method of this application, automatic feeding and one-time pressing operations of inner and outer rotors, motor housing and motor rotor can be realized, which can greatly improve processing efficiency, reduce equipment costs and make the size smaller.

[0031] Preferably, the floating fixture base includes a floating plate 303 with a through groove. A positioning seat 304 is detachably connected to the through groove. A support column 305 for supporting the inner and outer rotors passes through the positioning seat 304. A positioning pin 301 passes through the support column 305. The support column 305 is fixedly connected to the base plate 310. A spring 306 is sleeved on the support column 305. One end of the spring 306 is connected to the base plate 310, and the other end is connected to the positioning seat 304. With this design, during press-fitting, the support column 305 provides support force to the inner and outer rotors to prevent them from moving downwards. The floating positioning seat 304 is subjected to a holding force and moves downwards, completing the press-fitting operation between the positioning seat 304 and the inner and outer rotors. The overall structure is simple and has good stability.

[0032] Preferably, a plurality of guide sleeves 311 are provided on the base plate 310, and guide posts 312 are provided inside the guide sleeves 311. The plurality of guide posts 312 are fixedly connected to the floating plate 303. A plurality of buffer heads facing downward are provided on the floating plate 303. Support columns 305 are provided and fixed on the base plate 310, and cylinder brackets 313 for mounting floating cylinders 302 are provided on the base plate 310. The overall structure is simple and has good stability.

[0033] Preferably, the floating plate 303 is equipped with a first infrared beam detector 308 for detecting whether the inner and outer rotors are properly loaded and a second infrared beam detector 309 for detecting whether the motor housing is properly loaded. When both the first and second infrared beam detectors 308 and 309 are triggered, a signal is sent to trigger the floating cylinder 302 to lower the positioning pin to a first height, and the positioning pin partially retracts from the inner hole of the inner and outer rotors. This facilitates the detection of incoming material and also intelligently completes the automatic retraction control of the positioning pin, resulting in good overall performance and preventing material leakage.

[0034] Preferably, the press fitting machine 1 includes a press fitting head 10 and a press fitting frame 11. A pressure plate 12 for holding the motor housing is longitudinally slidably connected to the press fitting frame 11. The movable end of the press fitting head 10 is provided with a positioning hole 100 for positioning the shaft of the motor rotor. The movable end of the press fitting head 10 moves through the pressure plate 12. An annular plate 101 is fixedly sleeved on the movable end of the press fitting head 10. The annular plate 101 and the pressure plate 12 are connected by an elastic element 13. During press fitting, the movable end of the press fitting head 10 moves downward first, and the shaft of the motor rotor enters into the positioning hole 100 for positioning. At the same time, the pressure plate 12 holds the motor housing to ensure stability. Then, the movable end of the press fitting head 10 moves downward to press the motor rotor into the motor housing. Then, the pressure plate 12 is pushed downward by the annular plate 101. The motor housing and the inner and outer rotors are pressed together, and the motor rotor and the inner and outer rotors are pressed together. The machine has good integrity, high press fitting reliability, and high press fitting accuracy.

[0036] Preferably, the unloading robot 6 includes a clamping cylinder 60 and a rotary motor that drives the clamping cylinder to rotate. The two grippers of the clamping cylinder 60 are arranged longitudinally, and each gripper is fixed with a lifting cylinder 62. The movable end of the lifting cylinder 62 is provided with a transverse support plate 63 corresponding to the slot 3040. After the pressing machine 1 completes the pressing, the transverse transfer unit 31 drives the pressing fixture 30 to move to the unloading position, and the two support plates 63 are directly opposite the two slots 3040. Then, the floating cylinder 302 drives the positioning pin 301 to rise and lift the pressed product. When the lower end of the product exceeds the height of the support plate 63, it stops. The clamping cylinder 60 drives the two support plates 63 to clamp the product. A lifting cylinder drives two pallets 63 to rise, causing the product to detach from the positioning seat. The purpose of using this special pallet 63 structure in conjunction with the floating cylinder 302 and the slot 3040 to perform the above actions is to prevent the inner and outer rotors from falling downwards. This design is specifically designed to address the problem of inner and outer rotors falling off in actual situations. Furthermore, a flipping robot 9 is set on the processing table to hold the product on the unloading robot 6 and drive the product to rotate 180 degrees, so that the end where the inner and outer rotors are located faces upwards. This facilitates visual inspection of the inner and outer rotors and also avoids the problem of the inner and outer rotors falling off during the transfer of the inner and outer rotors in subsequent processes.

[0038] S01: The transverse unit drives the pressing fixture to the feeding position. The second feeding robot moves the inner and outer rotors supplied by the inner and outer rotor feeding assembly to the vision recognition assembly for visual recognition. The second feeding robot adjusts the angle of the visually recognized inner and outer rotors and feeds them to the pressing fixture. The positioning pin passes through the inner hole of the inner and outer rotors to position the inner and outer rotors.

[0039] S02: The first loading robot loads the motor housing from the loading conveyor belt into the pressing fixture. The motor housing is fitted outside the inner and outer rotors and positioned with the assistance of the positioning groove. The floating cylinder drives the positioning pin to descend to a first height, and the positioning pin partially exits the inner hole of the inner and outer rotors. The first loading robot loads the motor rotor from the loading conveyor belt into the motor housing on the pressing fixture. The lower end of the shaft of the motor rotor passes through the inner hole of the inner and outer rotors for positioning.

[0040] S03: The transverse unit moves the pressing fixture to the pressing position directly below the pressing machine. The pressing machine applies pressure to the motor rotor for one-time pressing. During the pressing process, the floating cylinder drives the positioning pin to cooperate with the moving end of the pressing machine to gradually descend to the second height until the positioning pin completely exits the inner hole of the inner and outer rotors. After pressing, the finished product is removed by the unloading robot.

[0041] By applying the method of this application, automatic feeding and one-time pressing operations of inner and outer rotors, motor housing and motor rotor can be realized, which can greatly improve processing efficiency, reduce equipment costs and make the size smaller.

[0042] It should be understood that those skilled in the art can make improvements or modifications based on the above description, and all such improvements and modifications should fall within the protection scope of the appended claims.
