[0017] In order to make the purpose, technical solutions and advantages of the utility model more clearly understood, the utility model is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the utility model and are not intended to limit the utility model.

[0018] In order to illustrate the technical solution of the present invention, specific embodiments are provided below.

[0019] For the sake of convenience, only the parts related to the embodiments of the present invention are shown.

[0020] Combine Figure 1-4 As shown, the positioning and grasping device includes a machine 1, a material rack 2 is provided on the machine 1, one side of the material rack 2 is open, and the other side facing the opening is provided with a push plate 3, and a liftable unloading rack 4 is provided on the machine 1 facing the opening, and the material rack 2 and the unloading rack 4 are both tilted and have the same inclination angle, and a loading rack 5 and a positioning mechanism are provided on the machine 1 facing the outlet of the unloading rack in sequence, and the positioning mechanism includes a positioning rack 6, a positioning wheel 7 is provided for rotation in the positioning rack 6, and the positioning wheel 7 is provided with a circle of positioning openings 8 along the circumferential direction, and a reduction motor 9 is provided in the machine 1, and a driving wheel 10 is provided on the driving shaft of the reduction motor 9, and a driven wheel 11 is provided on the shaft of the positioning wheel 7, and a belt 12 is provided between the driving wheel 10 and the driven wheel 11, and a grasping mechanism is provided on the machine 1 facing the positioning wheel 7.

[0021] In electricity and energy, a rotor refers to the component of a wind turbine that converts wind energy into mechanical energy. The crossflow impellers in air conditioners are composed of multiple rotors, commonly known as mid-rotor rotors. Mid-rotor rotors are typically injection molded in one go, and a small number of them may have burrs at the injection molding port. Staff will centrally select these mid-rotor rotors and place them in the material rack according to requirements.

[0022] When the impellers are fully placed on the material rack as required, and the impellers in the material rack are to be unloaded one by one and in an orderly manner onto the positioning mechanism, the unloading rack is first located at the loading waiting position, at which point the unloading rack is flush with the material rack. Then the pusher plate moves one position toward the opening, pushing all the impellers toward the opening, and a group of impellers close to the unloading rack is pushed onto the unloading rack. Then the unloading rack moves upward to the unloading position, at which point the bottom of the unloading rack is flush with the top of the loading rack.

[0023] After the unloading rack moves to the unloading station, its intermediate impellers roll one by one in an orderly fashion toward the loading rack. Prior to this, the positioning wheels remain stationary, with one of their positioning openings near the bottom of the loading rack. Once the lowest intermediate impeller has entered this opening, the reduction motor activates, and the belt drives the positioning wheels, slowly and clockwise, until the opening reaches the transfer position. The positioning wheels then stop, awaiting capture by the gripping mechanism and transfer to the next station. The unloading rack can be raised and lowered using a pneumatic cylinder.

[0024] In this embodiment, there are four positioning openings, each evenly spaced. Therefore, when the current positioning opening is rotated to the positioning transfer position, the positioning wheel rotates 90 degrees, and the penultimate wind wheel falls into the next positioning opening. The positioning mechanism allows each wind wheel to be sequentially transferred to the positioning transfer position, facilitating subsequent capture and transfer of the wind wheel.

[0025] In the above structure, if Figure 1-2 A baffle 13 is provided on the top surface of the material rack 2 near the opening. When the unloading rack rises to the unloading station, the impellers on the unloading rack sequentially move toward the loading rack. At this time, the baffle acts as a guide and limiter to prevent the impellers from falling into the material rack.

[0026] In this implementation, if Figure 2-3 The top surface of the machine 1 is provided with a long slot 14. A linear motor 15 is provided in the machine 1 opposite the long slot 14. A connecting bracket 16 is provided at the movable end of the linear motor 15. Both ends of the connecting bracket 16 penetrate into the material rack 2 and are connected to the push plate 3. A pair of avoidance grooves 17 are provided on the bottom surface of the material rack 2. Both ends of the connecting bracket 16 are located in the corresponding avoidance grooves 17.

[0027] When the push plate is to move one station toward the opening, the linear motor drives the moving end to move, and the moving end drives the push plate to move one station toward the opening under the action of the connecting frame. In this process, the avoidance groove plays the role of avoiding the connecting frame.

[0028] As a preferred structure, Figure 4 The grabbing mechanism includes a vertical frame 18, a rotatable flip frame 19 is provided on the vertical frame 18, a slide 20 is provided in the flip frame 19, the slide 20 is provided with a lifting plate 21 for vertical sliding, a clamping hand 22 is provided at the bottom of the lifting plate 21, and a lifting cylinder 23 is provided downwardly on the slide 20, the driving shaft of the lifting cylinder 23 is connected to the top of the clamping hand 22, and a moving cylinder 24 is also provided on the flip frame 19, and the driving shaft of the moving cylinder 24 is connected to the slide 20.

[0029] When the wind wheel is transferred to the positioning transfer position under the drive of the positioning wheel, the positioning wheel stops rotating, the gripper is located directly above the wind wheel, and the gripper is in an open state. At this time, the lifting cylinder drives the gripper downward until the wind wheel is clamped by the gripper. After that, the gripper is reset under the drive of the lifting cylinder, and the positioning wheel rotates and transfers the next wind wheel to the positioning transfer position. The moving cylinder can drive the slide to move along the length of the turning frame, thereby adjusting the position of the gripper.

[0030] In this structure, the shaft of the flip frame 19 passes through the vertical frame 18 and is provided with a flip seat 25. An arc groove 26 is opened below the flip seat 25. A flip cylinder 27 is rotatably provided on the vertical frame 18. The driving shaft of the flip cylinder 27 is rotatably provided with a short column 28, and the short column 28 is embedded in the arc groove 26.

[0031] After the gripper clamps the stroke wheel and resets under the drive of the lifting cylinder, the flip frame rotates toward the next workstation, and the gripper rotates until the stroke wheel rotates to the top of the next workstation. After the lifting cylinder drives the gripper closer to the next workstation, the gripper is released, the stroke wheel falls to the next workstation, and finally the gripper resets and the flip frame rotates in the opposite direction.

[0032] In the above structure, when the flip frame needs to rotate, the flip cylinder drives the flip seat to rotate forward. During this process, the flip frame rotates synchronously until the gripper rotates into place. During this process, when the flip cylinder drives the flip seat to rotate, the short post rotates within the arcuate groove. The arcuate groove acts as a limiter and guide for the short post, making the flip frame more stable during the flipping process.

[0033] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent replacements and improvements made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
