Description

A flipping device for transformer cores Technical Field

[0001] This utility model relates to the field of transformer core processing technology, and in particular to a flipping device for transformer cores. Background Technology

[0002] The transformer core is the core component of a transformer. It is usually made of stacked or wound silicon steel sheets with high magnetic permeability. Its main function is to provide a closed magnetic circuit with low magnetic resistance for alternating magnetic flux, reduce hysteresis and eddy current losses, and improve the energy conversion efficiency of the transformer. The manufacturing process of the transformer core requires a flipping operation so that its different faces are exposed to the processing equipment.

[0003] In existing technologies, traditional flipping methods rely on the cooperation of equipment and operators to flip the iron core, which not only increases the labor intensity of workers and has low production efficiency, but also poses significant safety hazards due to manual operation, making it difficult to meet the needs of modern large-scale production. Summary of the Invention

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a flipping device for transformer cores.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A flipping device for a transformer core includes a base, a conveying mechanism at the top center of the base, and a flipping mechanism at the top end of the base near the conveying mechanism. The flipping mechanism includes support plates fixedly connected to both sides of the top end of the base. A rotating rod is rotatably fitted on the top of each of the two support plates. A circular hole adapted to the rotating rod is opened on the top of each of the two support plates. A cylinder is fixedly connected between the two rotating rods. A U-shaped sleeve plate is fixedly fitted in the middle of the cylinder. A second servo motor is fixedly connected to the outside of the U-shaped sleeve plate. A U-shaped frame is fixedly connected to the output end of the second servo motor through the U-shaped sleeve plate and the cylinder. Sliding grooves are opened at both ends of the inner side of the U-shaped frame.

[0007] Preferably, the flipping mechanism further includes a U-shaped plate fixedly connected to the outside of one of the support plates, and the same worm gear is rotatably connected between the two sides of the inner wall of the U-shaped plate. A first servo motor is fixedly connected to the outside of the U-shaped plate, and the output end of the first servo motor passes through the U-shaped plate and is fixedly connected to the worm gear. A worm wheel is fixedly sleeved on the rotating rod near the worm gear, and the worm wheel meshes with the worm gear. By rotating the first servo motor in both directions, the U-shaped frame can rotate upward by 90 degrees with the iron core, which facilitates the subsequent rotation of the U-shaped frame.

[0008] Preferably, the conveying mechanism includes side plates fixedly connected to both sides of the top of the base. The same roller is rotatably connected between the top ends of the two side plates. The same conveyor belt is fitted on the two rollers. The conveyor belt is located inside the U-shaped frame. The top of the conveyor belt is adapted to the chute. The bottom of the chute is slightly lower than the top of the conveyor belt, ensuring that the iron core can smoothly enter the two chutes when it moves.

[0009] Preferably, the conveying mechanism further includes a drive motor fixedly connected to the outside of a side plate, and the output end of the drive motor passes through the side plate and is fixedly connected to one end of an adjacent roller.

[0010] Preferably, the top of the base near the conveying mechanism is also provided with a placement mechanism. The placement mechanism includes a U-shaped placement platform fixedly connected to the top of the base. A roller is provided on the side of the U-shaped placement platform near the conveyor belt, and the roller is adapted to the arc-shaped groove. The top of the U-shaped placement platform is slightly lower than the top of the conveyor belt.

[0011] Preferably, the placement mechanism further includes a mounting plate fixedly connected to the top of the placement mechanism at the end away from the conveying mechanism. An electric push rod is fixedly connected to the outside of the mounting plate, and an electromagnet is fixedly connected to the output end of the electric push rod through the mounting plate. The arrangement of the electromagnet and the electric push rod ensures that when the iron core moves between the U-shaped placement platform and the conveyor belt, the iron core can be moved to a suitable position and will not stay between the conveyor belt and the U-shaped placement platform.

[0012] Preferably, a controller is fixedly installed on the base, and the controller is electrically connected to the electric push rod, the electromagnet, the drive motor, the first servo motor and the second servo motor respectively.

[0013] The beneficial effects of this utility model are as follows:

[0014] 1. By employing a conveyor and a tilting mechanism, the iron core is transported by a conveyor belt to two chutes. As the tilting mechanism operates, the U-shaped frame carries the iron core around the cylinder, thus achieving the tilting. This effectively solves the problem of requiring manual intervention mentioned in the background technology. Furthermore, the coordinated operation of the conveyor belt and the tilting mechanism replaces manual handling and tilting operations, significantly reducing manual intervention, lowering labor costs, improving production efficiency and continuity, meeting the needs of large-scale production, and ensuring the personal safety of operators.

[0015] 2. By designing the placement mechanism, the iron core will not stop at the connection between the U-shaped placement platform and the conveyor belt when it is transferred between them, thus avoiding manual operation and further improving practicality. Attached Figure Description

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0022] Referring to Figures 1-4, a flipping device for a transformer core includes a base 1. A conveying mechanism 3 is provided at the middle of the top of the base 1. A flipping mechanism 4 is provided at one end of the top of the base 1 near the conveying mechanism 3. The flipping mechanism 4 includes support plates 401 fixedly connected to both sides of the top of the base 1. Rotating rods 406 are rotatably sleeved on the top of each of the two support plates 401. Circular holes adapted to the rotating rods 406 are opened on the top of each of the two support plates 401. A cylinder 405 is fixedly connected between the two rotating rods 406. A U-shaped sleeve plate 408 is fixedly sleeved in the middle of the cylinder 405. A second servo motor 409 is fixedly connected to the outside of the U-shaped sleeve plate 408. A U-shaped frame 410 is fixedly connected to the output end of the second servo motor 409 and the U-shaped sleeve plate 408 and the cylinder 405. Slide grooves 411 are opened at both ends of the inner side of the U-shaped frame 410. The core is located in the middle of the two slide grooves 411. When the slide grooves 411 rotate, the core can rotate and flip accordingly.

[0023] In this utility model, the flipping mechanism 4 also includes a U-shaped plate 403 fixedly connected to the outside of one of the support plates 401, and the same worm gear 404 is rotatably connected between the two sides of the inner wall of the U-shaped plate 403. A first servo motor 402 is fixedly connected to the outside of the U-shaped plate 403, and the output end of the first servo motor 402 passes through the U-shaped plate 403 and is fixedly connected to the worm gear 404. A worm wheel 407 is fixedly sleeved on the rotating rod 406 near the worm gear 404, and the worm wheel 407 meshes with the worm gear 404. The first servo motor 402 causes the U-shaped frame 410 to rotate with the cylinder 405 through the worm gear 404 and the worm wheel 407, so that when the U-shaped frame 410 flips with the iron core, it will not be obstructed by the conveyor belt 303.

[0024] In this utility model, the conveying mechanism 3 includes side plates 301 fixedly connected to the top two sides of the base 1. The top ends of the two side plates 301 are rotatably connected to the same roller 302. The same conveyor belt 303 is sleeved on the two rollers 302. The conveyor belt 303 is located inside the U-shaped frame 410, and the top of the conveyor belt 303 is adapted to the chute 411.

[0025] In this utility model, the conveying mechanism 3 also includes a drive motor 304 fixedly connected to the outside of a side plate 301. The output end of the drive motor 304 passes through the side plate 301 and is fixedly connected to one end of the adjacent roller 302. Through the operation of the conveyor belt 303, the iron core can move back and forth from the U-shaped placement platform 201 to the flipping mechanism 4.

[0026] In this utility model, a placement mechanism 2 is provided at the top of the base 1 near the conveying mechanism 3. The placement mechanism 2 includes a U-shaped placement platform 201 fixedly connected to the top of the base 1. A roller 302 is provided on the side of the U-shaped placement platform 201 near the conveyor belt 303, and the roller 302 is adapted to the arc-shaped groove 202.

[0027] In this utility model, the placement mechanism 2 also includes a mounting plate 203 fixedly connected to the top of the placement mechanism 2 at the end away from the conveying mechanism 3. An electric push rod 204 is fixedly connected to the outside of the mounting plate 203, and an electromagnet 205 is fixedly connected to the output end of the electric push rod 204 through the mounting plate 203. Through the setting of the electromagnet 205 and the electric push rod 204, the iron core can easily reach the conveyor belt 303 from the top of the U-shaped placement platform 201, and then return to the top of the U-shaped placement platform 201 from the conveyor belt 303.

[0028] In this utility model, a controller is fixedly installed on the base 1, and the controller is electrically connected to the electric push rod 204, the electromagnet 205, the drive motor 304, the first servo motor 402 and the second servo motor 409 respectively.

[0029] Working Principle: When using this device, the iron core is placed on top of the U-shaped placement platform 201 for processing. When the iron core needs to be flipped, the electromagnet 205 and electric push rod 204 are activated. The electric push rod 204 moves the electromagnet 205 towards one side of the conveyor belt 303. As the electromagnet 205 moves, it attracts the iron core, causing most of the iron core to move to the top of the conveyor belt 303. The conveyor belt 303 is higher than the U-shaped placement platform 201. The drive motor 304 is activated, causing the conveyor belt 303 to transport the iron core to the inside of the U-shaped frame 410. The bottom of the chute 411 is slightly higher than the top of the conveyor belt 303. When the iron core moves to the inside of the U-shaped frame 410, both ends of the iron core are exactly located on the two chute 411. In slot 411, the first servo motor 402 is activated, causing the worm gear 404 to rotate with the worm wheel 407, which in turn causes the cylinder 405 to rotate around the rotating rod 406 with the U-shaped sleeve 408 and the U-shaped frame 410. When the rotation is close to 90 degrees, the second servo motor 409 is activated, causing the U-shaped frame 410 to rotate half a turn with the iron core. Then the first servo motor 402 reverses, causing the U-shaped frame 410 to return to one end of the conveyor belt 303. At this time, the iron core contacts the conveyor belt 303. The drive motor 304 is then activated to reverse, causing the conveyor belt 303 to transport the iron core back to the U-shaped placement platform 201. Through the attraction of the electromagnet 205, the iron core returns to its original position at the top of the U-shaped placement platform 201, thus achieving the flipping process without manual operation.

[0030] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
