Description

Technical Field

[0001] This utility model relates to the technical field of transformer core production equipment, and in particular to a stacking mechanism for transformer cores. Background Technology

[0002] As a key piece of equipment in the power system, the transformer's core is the core component for electromagnetic conversion. It is usually made of multiple silicon steel sheets stacked in a specific way. The stacking quality of the core directly affects the transformer's working efficiency, losses, and operational stability.

[0003] In the production of transformer cores, the stacking of silicon steel sheets is a critical process. Traditional core stacking is mostly done manually, which is labor-intensive, inefficient, and makes it difficult to ensure the alignment accuracy between silicon steel sheets. Manual operation errors can easily lead to a decrease in the magnetic circuit performance of the core and increase the no-load loss of the transformer. Some automatic stacking equipment is prone to misalignment during the grabbing and transfer of silicon steel sheets and is not very efficient, making it impractical. Therefore, it is necessary to redesign a stacking mechanism for transformer cores to address the above problems. Utility Model Content

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

[0005] To achieve the above objectives, the present invention adopts the following technical solution: A stacking mechanism for transformer cores includes a base, a worktable fixedly mounted on the upper surface of the base, a bidirectional screw rotatably mounted on the inner wall of the worktable, a first motor fixedly mounted on the outer wall of the worktable and connected to the bidirectional screw, two first moving blocks threadedly mounted on the outer wall of the bidirectional screw via a limiting mechanism, each first moving block having a pressing plate fixedly mounted on it via a connecting mechanism, a rack slidably mounted on the bottom wall of the worktable via a sliding mechanism, and two rotating shafts on the inner wall of the worktable, one rotating shaft having a first gear fixedly mounted on its outer wall that meshes with the rack, and the other rotating shaft having a second gear fixedly mounted on its outer wall that meshes with the rack. A second motor connected to the first gear's rotating shaft is fixedly mounted on the wall via an mounting plate. A first support frame and a second support frame are fixedly mounted on the ends of the two rotating shafts, respectively. A first screw is rotatably mounted inside the first support frame. A third motor connected to the first screw is fixedly mounted on the upper surface of the first support frame. A second limiting rod is fixedly mounted inside the first support frame. A second moving block is rotatably mounted on the outer wall of the first screw via a thread. The second limiting rod slides through the second moving block. A first connecting rod is fixedly mounted on the outer wall of the second moving block. A second mounting frame is fixedly mounted at the end of the first connecting rod. Two first suction cups are fixedly mounted inside the second mounting frame via a vent pipe. A second screw is rotatably mounted inside the second support frame. A fourth motor connected to the second screw is fixedly mounted on the upper surface of the second support frame. A third limiting rod is fixedly mounted inside the second support frame. A third moving block is rotatably mounted on the outer wall of the second screw. The third limiting rod slides through the third moving block. A second connecting rod is fixedly mounted on the outer wall of the third moving block. A third mounting frame is fixedly mounted at the end of the second connecting rod. Two second suction cups are fixedly mounted inside the third mounting frame through a vent pipe.

[0006] Preferably, the limiting mechanism includes a first limiting rod fixedly installed on the inner wall of the workbench, the first limiting rod sliding through two first moving blocks.

[0007] Preferably, the connecting mechanism includes a connecting rod fixedly installed on the first moving block, the end of the connecting rod being connected to the outer wall of the extrusion plate, and an opening for the connecting rod to move on the upper surface of the worktable.

[0008] Preferably, the sliding mechanism includes two first mounting frames fixedly installed on the bottom wall of the workbench, and the rack is slidably installed inside the two first mounting frames.

[0009] Preferably, a first air pump is fixedly installed on the inner wall of the second mounting frame, and the first air pump is connected to the air pipe of the first suction cup through a hose; a second air pump is fixedly installed on the inner wall of the third mounting frame, and the second air pump is connected to the air pipe of the second suction cup through a hose.

[0011] The beneficial effects of this utility model are: 1. By setting up components such as a second motor, a first support frame, a second support frame, a first suction cup, and a second suction cup, the two support frames are installed in different positions. When the first suction cup faces left, the second suction cup faces the front. When the two mounting frames move down, the first suction cup adsorbs the silicon steel plate on the left side while the second suction cup releases the silicon steel sheet. By repeating the interchange operation, the first suction cup and the second suction cup work together alternately, thereby avoiding offset during stacking and improving efficiency.

[0012] 2. By setting up components such as a bidirectional screw, a first limiting rod, a first motor, a connecting rod, and an extrusion plate, the first motor is started to drive the bidirectional screw to rotate. Under the action of the first limiting rod, the two first moving blocks move towards each other. Thus, through the opening of the worktable, the connecting rod drives the extrusion plates to move closer to each other. This allows the silicon steel sheets to be aligned during stacking and is applicable to the stacking of silicon steel sheets of different sizes. Attached Figure Description

[0015] 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.

[0016] Reference Figure 1-5A stacking mechanism for transformer cores includes a base 1, a workbench 2 fixedly mounted on the upper surface of the base 1, the base 1 serving as the basic support for the entire mechanism and capable of stably supporting the workbench 2 fixedly mounted on the upper surface, a bidirectional screw 3 rotatably mounted on the inner wall of the workbench 2, and a first motor 4 connected to the bidirectional screw 3 fixedly mounted on the outer wall of the workbench 2, the outer wall of the bidirectional screw 3 having two first moving blocks 6 threadedly mounted through a limiting mechanism, the limiting mechanism including a first limiting rod 5 fixedly mounted on the inner wall of the workbench 2, the first limiting rod 5 slidingly passing through the two first moving blocks 6, causing the first moving blocks 6 to move along the direction of the bidirectional screw 3, each first moving block 6 having a pressing plate 8 fixedly mounted through a connecting mechanism, the connecting mechanism including a connecting rod 7 fixedly mounted on the first moving block 6, the end of the connecting rod 7 being connected to the outer wall of the pressing plate 8, the upper surface of the workbench 2 having an opening for cooperating with the movement of the connecting rod 7, ensuring that the connecting rod 7 moves unobstructed with the first moving block 6, when the two first moving blocks 6 approach or move away from each other, the pressing plate 8 can move synchronously to clamp the silicon steel sheet placed on the workbench 2; A rack 10 is slidably mounted on the bottom wall of the worktable 2 via a sliding mechanism. The sliding mechanism includes two first mounting frames 9 fixedly mounted on the bottom wall of the worktable 2. The rack 10 is slidably mounted inside the two first mounting frames 9. The inner wall of the worktable 2 is connected by two rotating shafts. A first gear 11 that meshes with the rack 10 is fixedly mounted on the outer wall of one rotating shaft, and a second gear 12 that meshes with the rack 10 is fixedly mounted on the outer wall of the other rotating shaft. A second motor 14 connected to the rotating shaft of the first gear 11 is fixedly mounted on the inner wall of the worktable 2 via a mounting plate 13. Driven by the second motor 14, the first gear 11 and the second gear 12 can rotate synchronously on the rack 10. Two rotating shafts are respectively fixedly installed with a first support frame 15 and a second support frame 24. A first screw 16 is rotatably installed inside the first support frame 15. A third motor 17 connected to the first screw 16 is fixedly installed on the upper surface of the first support frame 15. A second limiting rod 18 is fixedly installed inside the first support frame 15. A second moving block 19 is rotatably installed on the outer wall of the first screw 16. The second limiting rod 18 slides through the second moving block 19. A first connecting rod 20 is fixedly installed on the outer wall of the second moving block 19. A second mounting frame 21 is fixedly installed at the end of the first connecting rod 20. Two first suction cups 22 are fixedly installed inside the second mounting frame 21 through a vent pipe. A second air pump 32 is connected to the vent pipe of the second suction cup 31 through a hose. The hose connecting the vent pipe to the first air pump 23 is made of high-pressure resistant material to ensure the sealing of the gas release process. When the first air pump 23 works, the first suction cup 22 can generate a strong suction force to firmly adsorb the silicon steel sheet. With the movement of the second moving block 19, the silicon steel sheet can be accurately delivered to the designated position. A second screw 25 is rotatably installed inside the second support frame 24. A fourth motor 26 connected to the second screw 25 is fixedly installed on the upper end face of the second support frame 24. A third limiting rod 27 is fixedly installed inside the second support frame 24. A third moving block 28 is rotatably installed on the outer wall of the second screw 25. The third limiting rod 27 slides through the third moving block 28. A second connecting rod 29 is fixedly installed on the outer wall of the third moving block 28. A third mounting frame 30 is fixedly installed at the end of the second connecting rod 29. Two second suction cups 31 are fixedly installed inside the third mounting frame 30 through a vent pipe. A first air pump 23 is fixedly installed on the inner wall of the second mounting frame 21. The first air pump 23 is connected to the vent pipe of the first suction cup 22 through a hose. The second air pump 32 is fixedly installed on the inner wall of the third mounting frame 30. The second air pump 32 is connected to the air pipe of the second suction cup 31 through a hose. The electronic controller 33 is fixedly installed on the outer wall of the workbench 2. Its internal programming system can preset a variety of stacking programs. The electronic controller 33 can independently or collaboratively control the first motor 4, the second motor 14, the third motor 17, the fourth motor 26, the first air pump 23 and the second air pump 32. The whole process is highly automated, which greatly reduces the error of manual operation and improves the quality and efficiency of iron core stacking.

[0017] In use, the operator places the silicon steel sheets to be stacked on the left and right sides of the workbench 2 and at the stacking position. The first motor 4 is started by the electronic controller 33. The first motor 4 drives the bidirectional screw 3 to rotate. Under the restriction of the first limit rod 5, the two first moving blocks 6 move towards each other along the bidirectional screw 3, thereby driving the extrusion plates 8 to move closer to each other through the connecting rod 7 until the extrusion plates 8 contact the silicon steel sheets and clamp and position them. The clamping degree of the extrusion plates 8 is adjusted according to the size of the silicon steel sheets to ensure that the silicon steel sheets will not be displaced during the stacking process. The second motor 14 is started to drive the first gear 11 to rotate. Since the first gear 11 meshes with the rack 10, the rack 10 slides in the two first mounting frames 9. The rack 10 simultaneously drives the second gear 12 to rotate. Both the first gear 11 and the second gear 12 are incomplete gears.

[0018] The rotating shaft of the first gear 11 drives the first support frame 15 to rotate to the left, and the third motor 17 starts to drive the first screw 16 to rotate. Under the restriction of the second limit rod 18, the second moving block 19 moves downward along the first screw 16, thereby driving the second mounting frame 21 to move downward through the first connecting rod 20 until the first suction cup 22 contacts the silicon steel sheet to be stacked and adsorbs it. At the same time, the rotating shaft of the second gear 12 drives the second support frame 24 to rotate forward, and the fourth motor 26 drives the second screw 25 to rotate. Under the restriction of the third limit rod 27, the third moving block 28 drives the third mounting frame 30 to move downward to a suitable position through the second connecting rod 29. The electronic controller 33 controls the second air pump 32 to spray gas, which passes through the air pipe to the inside of the second suction cup 31, releasing the vacuum environment inside the second suction cup 31 and causing the silicon steel sheet to fall off. The silicon steel sheet after falling off is neatly stacked under the action of the two extrusion plates 8. As the first support frame 15 and the second support frame 24 rotate to the right, the left and right workstations exchange operation steps. In this way, the silicon steel sheet can be stacked layer by layer. The alternating work of the first suction cup 22 and the second suction cup 31 can avoid the displacement during stacking, and the synergistic effect of the left and right workstations greatly improves the production efficiency.

[0019] After the iron cores are stacked, all motors and air pumps are turned off, and the first motor 4 is started to make the bidirectional screw 3 rotate in the opposite direction, driving the two first moving blocks 6 to move in opposite directions. This causes the pressing plate 8 to be released through the two connecting rods 7, and the operator can remove the stacked transformer iron cores from the workbench 2.

[0020] 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.
