[0020] The present invention is further described below in conjunction with the accompanying drawings and specific embodiments so that those skilled in the art can better understand the present invention and implement it, but the embodiments are not intended to limit the present invention.

[0021] Reference Figure 1 As shown, an embodiment of the flipping and loading mechanism of the motor stator of the present invention includes an assembly platform 1, a horizontal slide 2 and a flipping mechanism 3, wherein the assembly platform 1 is arranged on the horizontal slide 2, the assembly platform 1 is used to place the motor stator, the flipping mechanism 3 is arranged on one side of the horizontal slide 2, the flipping mechanism 3 includes a stator core positioning jig 31 and a flipping drive source 32, the horizontal slide 2 drives the assembly platform 1 to move toward or away from the flipping mechanism 3, during the movement, the stator core positioning jig 31 is inserted into the stator inner core, and the flipping drive source 32 drives the stator core positioning jig 31 and the motor stator to rotate.

[0022] The working process of the motor stator flipping feeding mechanism in this embodiment is as follows: first, slide the horizontal slide 2 to the side away from the flipping mechanism 3, place the motor stator on the assembly platform 1 to fix its position, move the horizontal slide 2 in the direction close to the flipping mechanism 3, and send the motor stator into the flipping mechanism 3 through the horizontal slide 2. The stator core positioning jig 31 on the flipping mechanism 3 is inserted into the stator inner core. The flipping driving source 32 drives the stator core positioning jig 31 and the motor stator to rotate and move the angle. The motor stator angle is flipped by the flipping mechanism 3. After the flipping is completed, the motor stator is pulled out of the stator core positioning jig 31 by the mechanical arm on other equipment. The motor stator flipping feeding mechanism of this embodiment realizes the automatic feeding action of large motor stators, improves the feeding efficiency, and avoids equipment bumps and damages caused by manual handling.

[0023] Specifically, in order to ensure that the motor stator can be stably placed on the assembly platform 1, the assembly platform 1 includes a platform frame 11, and a plurality of support rollers 12 are arranged on the platform frame 11. The plurality of support rollers 12 form an arc surface, and the arc surface has the same curvature as the motor stator shape.

[0024] Reference Figure 2As shown, a positioning mechanism 4 is provided below the assembly platform 1, and the positioning mechanism 4 includes a positioning joystick 41, a joystick gear slot 42 and a positioning block 43. The joystick gear slot 42 includes two gears. The positioning joystick 41 moves between the two gears in the joystick gear slot 42 to drive the positioning block 43 to move up and down. Two positioning protrusions 44 for positioning the stator are protruding from the end of the positioning block 43. Before the motor stator is placed on the assembly platform 1, the positioning joystick 41 is controlled to be in a low gear, and the positioning block 43 is located below the assembly platform 1. After the motor stator is placed on the assembly platform 1, the positioning joystick 41 is controlled to be in a high gear, and the positioning block 43 protrudes from the assembly platform 1. The two positioning protrusions 44 are stuck at both ends of the motor stator to prevent the motor stator from rotating on the assembly platform 1. The positioning mechanism 4 plays a positioning locking function for the motor stator.

[0025] Reference Figure 2 As shown, the horizontal slide 2 includes two parallel linear slide rails 21, the linear slide rails 21 are "I"-shaped slide rails, and a slide 22 matching the "I"-shaped slide rail is arranged on the linear slide rail 21. The assembly platform 1 is fixed on the slide 22, and the slide 22 is buckled with the "I"-shaped slide rail to ensure that the slide 22 does not tilt left and right during the movement on the slide rail, and at the same time, it can also prevent the slide 22 from falling off the linear slide rail 21. A rack 23 parallel to the two linear slide rails 21 is arranged between them, and a drive motor 24 meshing with the rack 23 is arranged on the assembly platform 1. The drive motor 24 is fixed on the assembly platform 1, and the drive motor 24 rotates and meshes with the rack 23 to drive the assembly platform 1 to slide on the linear slide rail 21.

[0026] Specifically, the flipping drive source 32 is a hydraulic cylinder or a servo motor, and the hydraulic cylinder controls the flipping angle by controlling the stroke; the servo motor controls the flipping angle through the electronic control system. The flipping drive source 32 in this embodiment is controlled by a servo motor, and the flipping drive source drives the stator core positioning jig to rotate 0 to 90°, which is suitable for loading at different workstations.

[0027] Specifically, the diameter of the stator core positioning jig 31 is smaller than the diameter of the stator inner core. After the stator core positioning jig 31 is inserted into the stator inner core, it is matched with the stator inner core gap to ensure that the stator core positioning jig 31 can be inserted into the stator inner core, and to ensure that when the stator core positioning jig 31 drives the stator inner core to flip, the motor stator will not shake on the stator core positioning jig 31, and the stator inner core will not slide relative to the stator core positioning jig 31.

[0028] This embodiment also includes a bracket, and the assembly platform 1, the horizontal slide 2 and the flip mechanism 3 are all arranged on the bracket 5. The corners below the bracket 5 are provided with supporting feet 6, and the supporting feet 6 are also provided with locking fixing plates 7. The bracket 5 is fixed to the ground by the locking fixing plates 7 to prevent the position of the bracket 5 from moving due to inertia during the placement of the motor stator.
