[0002] A rotor motor is a type of motor that works based on electromagnetic induction. A rotor motor is generally divided into a rotor and a stator. The stator is the fixed part. During the stator installation process, the stator needs to be placed on the stator slot of the motor to ensure that the stator is aligned with the locating pins or slots of the motor. At the same time, use screws or other fixing devices to fix the stator to the stator slot of the motor to ensure that the stator does not loosen or move.

[0003] Existing assembly methods are generally divided into press-in assembly, bolt fixing, bonding fixing, laser welding and surface treatment. Among them, press-in assembly requires precise control of the pressing force to prevent damage to parts, while bonding fixing can provide higher structural strength and fixing effect by glue, and can also reduce vibration and noise. Therefore, bonding fixing is used in more motor installations.

[0004] However, the existing bonding and fixing of motor stators, on the one hand, only processes a single stator during the bonding process, resulting in low processing efficiency; on the other hand, the motor housing together with the stator is directly removed after the bonding is completed, reducing the glue solidification effect between the motor housing and the stator.

[0027] A downward pressure rod 5 is slidably connected to the support plate 2, one end of which is inserted into the shaft sleeve 4 and the other end of which extends out of the hollow motor 3. A plug hole 6 for fixing the motor housing is opened in the shaft sleeve 4. One end of the downward pressure rod 5 is inserted into the shaft sleeve 4 and is used in conjunction with the plug hole 6. A downward push cylinder used in conjunction with the downward pressure rod 5 is provided on the support plate 2. The downward push cylinder drives the downward pressure rod 5 to move downward, and at the same time, the cylinder housing is driven out of the shaft sleeve 4 under the action of the downward pressure rod 5.

[0028] A plurality of core jigs are arranged in the frame 1 for installing the core module. The core jig is used in conjunction with the shell jig, wherein the outermost core jig is located directly below the extreme position of the shell jig. The core jig is used to place the stator core inserted into the motor housing.

[0029] The core fixture includes a fixed shaft 11 for positioning and fixing the core. One end of the fixed shaft 11 is fixedly connected to the frame 1 via a rotating motor 12. Multiple core fixtures are arranged along the output shaft direction of the drive structure. The fixed shaft 11 is used to limit and fix the stator core. Multiple core fixtures can place and spray glue on multiple stator cores at the same time.

[0030] Sensors 13 are fixedly connected to both sides of the fixed shaft 11 , respectively. The sensors 13 monitor the position of the stator core. Meanwhile, the sensors 13 can also monitor the motor housing installed on the stator core.

[0031] The driving structure is used to drive the housing jig. The driving structure drives the housing jig to move. On the one hand, the housing jig is driven to move to just above a suitable iron core jig. On the other hand, the housing jig is driven to move to the housing glue gun to spray glue on the inner edge surface of the motor housing.

[0032] The driving structure includes a support frame 7 fixedly connected to the frame body 1, and a driving motor 8 is rotatably connected to the support frame 7. A slide plate 9 is threadedly connected to the output shaft of the driving motor 8 and is slidably connected to the support frame 7. The slide plate 9 is used in conjunction with the support plate 2 through the outer shell lifting cylinder 10. Under the action of the output shaft of the driving motor 8 and the slide plate 9, the outer shell lifting cylinder 10 is driven to move left and right. At the same time, the outer shell lifting cylinder 10 drives the support plate 2 thereon to move up and down.

[0033] A core glue gun is arranged on one side of the core fixture for coating the outer side of the core. The core glue gun is used to spray the accelerator on the outer edge surface of the stator core. The core glue gun is used in conjunction with the core fixture to achieve uniform spraying of the outer edge surface of the stator core during rotation.

[0034] The core glue gun includes a vertical spraying device containing a accelerator, and the vertical spraying device is used in conjunction with the core fixture via a movable cylinder 14. The movable cylinder 14 can move the vertical spraying device to a suitable position of the core fixture.

The above two types of cylinders enable the first spray gun 16 to adapt to stator cores of various sizes.

[0036] A shell glue gun is arranged on the other side of the core fixture for applying glue to the inner wall of the motor shell. The shell glue gun is used to spray glue on the inner edge surface of the motor shell. The stator core is fixed in the motor shell under the combined action of glue and accelerator.

[0037] The shell glue gun includes an epoxy glue gun 18 fixedly connected to the frame 1 via a glue gun lifting cylinder 17. The epoxy glue gun 18 and the horizontal plane of the frame 1 are inclined at an angle of 15 degrees toward the shell fixture. In the inclined state, the epoxy glue gun 18 can better fit the inner edge surface of the motor shell.

[0038] When the utility model is used, the staff fixes the motor housing on the shaft sleeve 4 through interference fit or electromagnetic magnetic force adsorption, and fixes the stator core on the fixed shaft 11. When the motor housing and the stator core are fixed, the staff starts the drive motor 8. Under the action of the drive motor 8, the slide plate 9 moves the support plate 2 and the motor housing thereon to the epoxy glue gun 18. At the same time, the epoxy glue gun 18 is located at the center of the motor housing, and the output end of the epoxy glue gun 18 is used in conjunction with the inner edge surface of the motor housing.

[0039] Under the action of the hollow motor 3, the shaft sleeve 4 drives the motor housing thereon to rotate, and at the same time, the epoxy glue gun 18 starts to extrude the epoxy glue, so that the epoxy glue is coated on the inner edge surface of the motor housing. During the epoxy glue coating process, the motor housing or the epoxy glue gun 18 can move up and down, so that the epoxy glue can be coated on the inner edge surface of the motor housing more evenly;

[0040] At the same time, the moving cylinder 14 drives the first spray gun 16 to move toward the stator core. Under the action of the position adjustment cylinder 15 and the rotating motor 12, the accelerator in the first spray gun 16 can be better sprayed onto the outer edge surface of the stator core.

[0041] When the motor housing and the stator core are sprayed, the driving motor 8 drives the motor housing to move to the top of the stator core sprayed with the accelerator. Under the action of the housing lifting cylinder 10, the motor housing approaches the stator core and presses down, so that the stator core is inserted into the motor housing. Under the action of the accelerator and the epoxy glue, the stator core and the motor housing are fixed.

[0042] After the stator core is inserted into the motor housing, on the one hand, the pressure rod 5 moves downward to push out the motor housing, and on the other hand, the housing lifting cylinder 10 starts and moves upward to promote the pressure rod 5 to push out the motor housing. After the pushing is completed, the motor housing and the stator core remain on the fixed shaft 11 for a period of time for pressure maintenance treatment.

[0043] The utility model utilizes a lower pressure rod and a shell lifting cylinder to automatically separate the bonded motor shell from the fixed shaft, and the bonded motor shell can be pressure-maintained on the fixed shaft, so that the bonded motor shell can be better fixed to the stator core;
