Description

Technical Field

[0001] This utility model relates to the field of stator and rotor core technology, specifically to an automatic stator and rotor core discharge and collection device. Background Technology

[0002] An electric motor is an electromagnetic device that converts or transmits electrical energy based on the law of electromagnetic induction. Its main function is to generate driving torque and serve as a power source for electrical appliances or various machines. A generator is represented by the letter G in a circuit. Its main function is to convert electrical energy into mechanical energy. The structure of a three-phase asynchronous motor consists of a stator, a rotor, and other accessories. During the production of the motor, the stator and rotor are made by stamping cold-rolled steel sheets. After the stator and rotor cores are stamped, they are automatically discharged by the equipment, transported by a conveyor, and then picked up by a robotic arm and collected in a collection frame. A limit mechanism is set to fix the collection frame in a fixed position.

[0003] For example, Chinese utility model patent CN111799965A discloses a shaping device for wound stator cores, relating to the field of stator shaping equipment. It includes a base, a support on the base, a sliding seat vertically slidably connected to the support, a fixed mold on the base, and a moving mold on the lower end face of the sliding seat. A support extends from one side of the base, a conveyor belt is horizontally mounted on the support, and an arc-shaped mounting plate is positioned between the conveyor belt and the fixed mold. A mounting column is mounted on the support, and a turntable located above the mounting plate is intermittently rotatably connected to the mounting column. The turntable has a groove connecting the conveyor belt and the fixed mold for the stator core to be embedded in. A collection mechanism is located behind the fixed mold on the base. This application has the following advantages and effects: by setting up a highly automated shaping device, automatic transmission, automatic shaping, and automatic collection of the stator core are achieved, realizing continuous shaping of the stator core, replacing manual labor, and thus improving the shaping efficiency of the stator core.

[0004] However, existing automatic stator and rotor core collection devices automatically discharge and transport the cores to a conveyor belt via the discharge port, and then use a robotic arm to grab the cores and collect them in a collection frame placed at a fixed position. When the amount of cores collected in the collection frame reaches the target, the collection frame needs to be replaced manually, and it is quite laborious to lift the collection frame manually when it is full of cores.

[0005] Therefore, we propose an automatic stator and rotor core discharge and collection device to solve the above problems. Utility Model Content

[0006] The purpose of this invention is to provide an automatic discharge and collection device for stator and rotor cores to solve the problems mentioned in the background art.

[0007] To achieve the above objectives, this utility model provides the following technical solution: an automatic discharge and collection device for stator and rotor iron cores, comprising a base plate and a collection frame. An inclined slope is fixedly connected to one side of the base plate, and fixed limiting frames are fixedly connected to both ends of the top surface of the base plate. An installation groove is opened on one side of the base plate, and a motor is fixedly installed in one side of the installation groove. One end of a positive and negative lead screw is fixedly connected to the motor shaft, and the other end of the positive and negative lead screw is rotatably connected to the base plate. Sliding grooves are opened at both ends of the top surface of the base plate, and the positive and negative lead screws are rotatably connected to the sliding grooves. A moving block is slidably connected in the sliding groove, and a threaded sleeve is embedded in the moving block. The threaded sleeve is threadedly connected to the positive and negative lead screws. There are two moving blocks, and movable limiting frames are fixedly connected to the top surfaces of the two moving blocks. Multiple support seats are fixedly connected to the bottom surface of the collection frame, and rollers are fixedly installed at the bottom of the support seats. The bottom ends of the rollers contact the base plate.

[0008] Preferably, the support base contacts the fixed limiting frame and the movable limiting frame.

[0009] Preferably, mounting plates are fixed to both sides of the base plate, and the mounting plates are provided with mounting holes.

[0010] Preferably, handles are fixed to both ends of the collection frame.

[0011] Preferably, the movable limiting frame is slidably connected to the top surface of the base plate.

[0012] Preferably, the horizontal cross-sectional shape of both the fixed limiting frame and the movable limiting frame is L-shaped.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] This invention, by setting up a support base, rollers, fixed limiting frames, a motor, positive and negative lead screws, a moving block, and movable limiting frames, can collect a sufficient amount of iron cores in the collection box. After the collection box is collected, the two movable limiting frames are moved away from each other by the drive motor, releasing the restriction on one side of the collection box. This allows the collection box to slide out onto the inclined slope side via the rollers. Then, the two movable limiting frames are moved back to their original positions by the drive motor. Workers can then place another empty collection box into the bottom support base corresponding to the fixed limiting frame and movable frame positions to continue the collection work. This facilitates the replacement of the collection box and saves effort by eliminating the need for manual lifting. Attached Figure Description

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model. Example

[0020] Please see Figure 1-3 This is the first embodiment of the present invention, which provides a technical solution: an automatic discharge and collection device for stator and rotor iron cores, comprising a base plate 1 and a collection frame 6. An inclined slope 4 is fixedly connected to one side of the base plate 1 to facilitate moving the collection frame 6 to the ground. Fixed limiting frames 5 are fixedly connected to both ends of the top surface of the base plate 1. An installation groove 10 is formed on one side of the base plate 1, and a motor 11 is fixedly installed in one side of the installation groove 10. One end of a positive and negative lead screw 12 is fixedly connected to the shaft of the motor 11, and the other end of the positive and negative lead screw 12 is rotatably connected to the base plate 1. Slide grooves 13 are opened at both ends of the top surface. The positive and negative lead screws 12 are rotatably connected to the slide grooves 13. The sliding block 14 is slidably connected to the slide groove 13. The threaded sleeve 141 is embedded in the sliding block 14. The threaded sleeve 141 is threadedly connected to the positive and negative lead screws 12. There are two sliding blocks 14. The top surfaces of the two sliding blocks 14 are respectively fixed to the movable limit frame 15. The bottom surface of the collection frame 6 is fixed to multiple support seats 8. The bottom of the support seat 8 is fixedly installed with rollers 9. The bottom end of the rollers 9 contacts the base plate 1. The rollers 9 can roll on the base plate 1 and the inclined slope 4. Example

[0021] Please see Figure 1-3 This is the second embodiment of the present invention. Based on the previous embodiment, the support base 8 contacts the fixed limiting frame 5 and the movable limiting frame 15, which can effectively limit the collection frame 6 and facilitate the collection of iron cores.

[0022] Mounting plates 2 are fixed to both sides of the base plate 1. Mounting plates 2 are provided with mounting holes 3, which can be used to fix the base plate 1 to a suitable position on the ground.

[0023] Handles 7 are fixed to both ends of the collection box 6 to facilitate pushing, pulling and placing the collection box 6.

[0024] The movable limit frame 15 slides to connect the top surface of the base plate 1.

[0025] The horizontal cross-sectional shape of both the fixed limiting frame 5 and the movable limiting frame 15 is L-shaped, which can effectively limit the collection frame 6.

[0026] Please see Figure 1-3 In practical use, the stator and rotor cores are automatically discharged onto a conveyor for transport. The collection frame 6 is fixed in a fixed position. The robotic arm can grab the cores from the conveyor and collect them into the collection frame 6. Once the amount of cores collected in the collection frame 6 reaches the target, the motor 11 is connected to an external power source and manually started. This drives the forward and reverse lead screws 12 to rotate, causing the moving blocks 14 and the movable limit frame 15 at both ends to move away from each other. The movable limit frame 15 moves to a suitable position, causing it to detach from the collection frame 6, thus releasing the restriction on one side of the collection frame 6. Workers can pull the collection box 6 towards the inclined slope 4 by pulling the handle 7. Then, the drive motor 11 drives the two movable limit frames 15 to move closer to each other and back to their original positions. Workers can then insert another empty collection box 6 into the bottom support 8, corresponding to the positions of the fixed limit frame 5 and the movable limit frame 15. The fixed limit frame 5 and the movable limit frame 15 can limit the collection box 6, allowing the collection of iron cores to continue. The collection box 6 containing iron cores can be moved to a suitable position via the rollers 9, facilitating the replacement of the collection box 6. It is not necessary to manually lift the collection box 6 to remove it from the limit mechanism, making it more labor-saving.
