Description

Technical Field

[0001] The present application relates to the technical field of transformer core lamination equipment, and in particular to a core lamination device for transformer processing. Background Art

[0002] During the production and processing of transformers, a core lamination device is required to sequentially stack silicon steel sheets to form an iron core. The existing core lamination device includes two lamination carriers and a lamination table. The lamination carriers are respectively stacked with horizontal and vertical silicon steel sheet stacks. The spacing between the silicon steel sheet stacks in the same direction matches the spacing between adjacent silicon steel sheets in the iron core. During the core stacking process, two suction cup assemblies provided on a movable assembly can clamp the silicon steel sheets required for each layer of the iron core at a time. The suction cup assemblies can absorb and clamp multiple silicon steel sheets at a time. Driven by the movable assembly, the two suction cup assemblies are sequentially placed at the rated positions on the lamination table. Magnetic spreaders are arranged on both sides of the lamination plate to separate the silicon steel sheets at the top of the corresponding silicon steel sheet stacks to avoid clamping heavy sheets.

[0003] However, existing core lamination devices, due to the hierarchical design of some transformer cores, require a stepped structure of silicon steel sheets of varying widths stacked in the core column cross-section. Each level corresponds to a number of silicon steel sheets of a specific width and thickness, achieving a nearly circular core cross-section through multiple stacking steps. Consequently, the stack of silicon steel sheets on the carrier plate also requires a specific number of silicon steel sheets, and each level corresponds to a specific number of silicon steel sheets. This results in varying spacing between silicon steel sheets of varying specifications and the magnetic spreader, impacting the separation and positioning accuracy of the magnetic spreader. This in turn reduces subsequent lamination accuracy, affecting transformer production quality. Summary of the Invention

[0004] The present application proposes a core lamination device for transformer processing, which has the advantage of adjusting the spacing of magnetic spreaders according to silicon steel sheets of different specifications, and is used to solve the problem that the magnetic spreader is difficult to adapt to the corresponding silicon steel sheets of different levels in the material pile.

[0013] Furthermore, it also includes a suction cup assembly, and a distance sensor is fixedly connected to one side of the bottom of the suction cup assembly.

DETAILED DESCRIPTION

[0026] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0027] Example 1, as Figure 1-Figure 7 , a core lamination device for transformer processing, comprising a suction cup assembly 2 and a support seat 1, the number of the suction cup assembly 2 and the support seat 1 are both set to two, the two support seats 1 are used to place silicon steel sheets 6 in different directions respectively, that is, the silicon steel sheets 6 on one of the two support seats 1 are piled up longitudinally, and the silicon steel sheets 6 on the other of the two support seats 1 are placed transversely, and the spacing between adjacent silicon steel sheets 6 corresponding to the single support seat 1 is equal to the spacing between adjacent silicon steel sheets 6 corresponding to the iron core to be stacked, so that the suction cup assembly 2 can absorb and clamp multiple silicon steel sheets 6 at a time and then place and stack them without adjusting the spacing between the sucked silicon steel sheets 6. A movable plate 3 is slidingly provided on the top of the support seat 1, see Figure 4 , a number of lifting plates 5 are arranged on the top of the movable plate 3.

[0028] The front and back sides of the lifting plate 5 are fixedly connected with positioning rods 16, which are slidably connected to the movable plate 3. The positioning rods 16 can slide up and down relative to the movable plate 3. A plurality of positioning plates 8 are provided on the top of the support seat 1, and a magnetic spreader 10 is fixedly provided on one side of the positioning plate 8. The plurality of positioning plates 8 are grouped in pairs and the number of positioning plate 8 groups is adapted to the number of iron core columns in the corresponding direction of the stacked iron core. Each group of positioning plates 8 cooperates with each other to position the corresponding silicon steel sheet 6 pile. The plurality of lifting plates 5 are divided into a plurality of groups and the number of lifting plate 5 groups is adapted to the number of iron core columns in the corresponding direction of the iron core. The number of lifting plates 5 corresponding to each group of lifting plates 5 is adapted to the number of levels of silicon steel sheet 6 piles, that is, the lifting plates 5 are used to place silicon steel sheet 6 piles of a single specification, and the specifications of the silicon steel sheets 6 corresponding to a group of lifting plates 5 meet the stacking requirements of the corresponding positions of the iron core.

[0029] The movable plate 3 can slide horizontally relative to the support base 1 and the sliding direction is perpendicular to the arrangement direction of the silicon steel sheet 6 material pile, that is, the movable plate 3 corresponding to the vertically arranged silicon steel sheet 6 material pile is horizontally sliding, see Figure 3 , the top of the support base 1 is fixedly connected with several fixing plates 4, see Figure 7 , a fixed tube 11 is fixedly sleeved on one side of the fixed plate 4, and a sliding rod 12 is slidably sleeved on one side of the fixed tube 11. One side of the sliding rod 12 is T-shaped and a protrusion 14 is fixedly connected to the top of the sliding rod 12. The protrusion 14 is used to limit the rotation of the sliding rod 12 relative to the fixed tube 11. The sliding rod 12 can slide axially relative to the fixed tube 11 without separating from the fixed tube 11. A return spring 13 is fixedly connected to one side of the sliding rod 12, and one end of the return spring 13 is fixedly connected to the inner wall of the fixed tube 11. The sliding rod 12 is fixedly connected to the corresponding positioning plate 8. Avoidance grooves 9 are provided on the front and back sides of one side of the positioning plate 8. The position of the avoidance groove 9 matches the position of the corresponding positioning rod 16.

[0030] One side of the top of the support base 1 is fixedly connected to a connecting base 28, and a No. 1 telescopic mechanism 18 is fixedly provided on the top of the connecting base 28. The number of the No. 1 telescopic mechanism 18 corresponds to the number of the 5 groups of lifting plates. The No. 1 telescopic mechanism 18 is set as an electric push rod. Figure 5 The bottom of the lifting plate 5 is fixedly connected to a connecting block 17 at the midpoint, and a telescopic mechanism 18 is used to push the connecting block 17 up. Figure 1 A No. 2 telescopic mechanism 27 is fixedly connected to one side of the top of the support seat 1. The No. 2 telescopic mechanism 27 is set as an electric push rod. The output end of the No. 2 telescopic mechanism 27 is fixedly connected to the movable plate 3. The suction cup assembly 2 is installed on the movable assembly. A distance sensor 26 is fixedly connected to one side of the bottom of the suction cup assembly 2.

[0031] The distance sensor 26 is used to detect the distance between the suction cup assembly 2 and the silicon steel sheet 6 on the top surface of the core, so as to judge the thickness of each level of the silicon steel sheet 6 of the core during the stacking process. The thickness of the silicon steel sheet 6 corresponding to the lifting plate 5 in the moving direction of the moving plate 3 in a single group increases in sequence. The top and back of the lifting plate 5 are fixedly provided with guide rods 7 with shapes that match the corresponding silicon steel sheets 6 to facilitate the positioning and centering of the silicon steel sheets 6. The top of the support base 1 is provided with an adjustment component that can adjust the spacing between the corresponding positioning plates 8. Figure 4 The movable plate 3 is provided with a plurality of through slots, and the positions of the through slots correspond to the positions of the lifting plate 5 .

[0032] When in use, the No. 2 telescopic mechanism 27 drives the movable plate 3 to move, so that the lifting plate 5 corresponding to the silicon steel sheet 6 required for the core stacking moves to the bottom of the center between the two positioning plates 8, and the connecting block 17 corresponding to the lifting plate 5 corresponds to the position of the No. 1 telescopic mechanism 18 at the bottom. Several No. 1 telescopic mechanisms 18 are extended, and the No. 1 telescopic mechanism 18 extends through the through slot and pushes the connecting block 17 to rise. The connecting block 17 drives the lifting plate 5 to rise, and the transmission mechanism drives the two positioning plates 8 to approach each other until the No. 1 telescopic mechanism 18 extends to the rated length. At this time, the top of the positioning rod 16 is embedded in the corresponding avoidance groove 9, and the height of the lifting plate 5 corresponds to the height of the positioning plate 8. The lifting plate 5 is located between the two positioning plates 8, and the two positioning plates 8 are fitted with the side faces of the lifting plate 5. The width of the lifting plate 5 is adapted to the width of the silicon steel sheet 6 of corresponding specifications.

[0033] Therefore, the positioning plate 8 positions the silicon steel sheet 6 to ensure the positioning accuracy in the subsequent separation and adsorption fixation process. The magnetic spreader 10 is started, and the suction cup assembly 2 simultaneously absorbs the silicon steel sheets 6 of several silicon steel sheet 6 piles and stacks them to the rated position. After the silicon steel sheets 6 of the corresponding specifications of the iron core are stacked, the No. 1 telescopic mechanism 18 contracts and resets, and the lifting plate 5 descends and resets. The No. 2 telescopic mechanism 27 drives the movable plate 3 to move again, and the movement of the movable plate 3 drives the positioning rod 16 to move, and the positioning rod 16 drives the corresponding lifting plate 5 to move.

[0034] Switch the lifting plate 5 corresponding to the No. 1 telescopic mechanism 18, and the No. 1 telescopic mechanism 18 and the transmission mechanism adjust the positions of the positioning plate 8 and the lifting plate 5 again, and cooperate with the suction cup assembly 2 to stack the silicon steel sheets 6 of different layers of the iron core in turn. The thickness of the silicon steel sheets 6 corresponding to the lifting plates 5 in a single group gradually changes. Therefore, after the No. 2 telescopic mechanism 27 completes a round of telescoping, the plane size of the silicon steel sheets 6 at various parts of the iron core is changed from small to large and then from small to small. By adjusting the positions of the positioning plate 8 and the lifting plate 5, the magnetic spreader 10 can adapt to silicon steel sheets 6 of different specifications, and the different lifting plates 5 are driven by the moving plate 3 to correspond to the positions of the No. 1 telescopic mechanism 18. While keeping the suction cup assembly 2 able to synchronously clamp multiple silicon steel sheets 6 and ensuring the separation effect of the magnetic spreader 10 on the silicon steel sheets 6, the magnetic spreader 10 can adapt to silicon steel sheets 6 of different specifications.

[0035] It also avoids the existence of silicon steel sheets 6 of different specifications in the silicon steel sheet pile corresponding to a single lifting plate 5, thereby avoiding the situation where the magnetic spreader 10 acts on the junction of silicon steel sheets 6 of different levels in a single pile after adjusting the spacing. When the magnetic spreader 10 adapts to the larger silicon steel sheets 6 and separates the silicon steel sheets 6 of different sizes, the smaller silicon steel sheets 6 are lifted and separated between the large-spacing magnetic spreaders 10, resulting in a lack of effective limiting, and there is a certain fluctuation in the thickness of silicon steel sheets 6 of different levels in the pile. When a single lifting plate 5 corresponds to silicon steel sheets 6 of different specifications, the spacing of the magnetic spreader 10 can easily lead to contact with the silicon steel sheets 6, resulting in deformation of the silicon steel sheets 6. Therefore, the reliability of the core stacking device is improved and the accuracy of the core stacking is guaranteed.

[0036] The transmission mechanism includes several transmission shafts 19, and a connecting plate 25 is fixedly connected to one side of the fixed plate 4. The number of transmission shafts 19 corresponds to the number of connecting plates 25. The transmission shaft 19 and the connecting plate 25 are rotatably connected through bearings. Both ends of the transmission shaft 19 are fixedly sleeved with a transmission gear 21. The front and back surfaces of the connecting plate 25 are slidably clamped with a No. 2 rack 22. The No. 2 rack 22 and the corresponding transmission gear 21 are meshed with each other. The No. 2 rack 22 can slide up and down relative to the connecting plate 25. A connecting gear 20 is fixedly sleeved at the midpoint of the transmission shaft 19, and one end of the sliding rod 12 is fixedly connected to the No. 1 rack 15. The No. 1 rack 15 and the corresponding connecting gear 20 are meshed with each other. The bottom of the two No. 2 racks 22 located on both sides of the corresponding positioning plate 8 is fixedly connected to a connecting rod 23, see Figure 5 , adjustment rods 24 are fixedly connected to both sides of the connecting block 17.

[0037] When the No. 1 telescopic mechanism 18 is extended, the connecting block 17 rises and drives the adjusting rod 24 to rise. The adjusting rod 24 presses against the bottom of the connecting rod 23 and drives the connecting rod 23 to rise. The connecting rod 23 drives the corresponding No. 2 rack 22 to rise. The No. 2 rack 22 drives the corresponding transmission gear 21 to rotate. The transmission gear 21 drives the transmission shaft 19 to rotate. The transmission shaft 19 drives the corresponding connecting gear 20 to rotate. The connecting gear 20 drives the horizontally arranged No. 1 rack 15 to move horizontally, and cooperates with the sliding rod 12 to drive the positioning plate 8 to move, so that the corresponding two positioning plates 8 are close to each other. After the No. 1 telescopic mechanism 18 retracts, the reset spring 13 pulls the sliding rod 12 to retract into the fixed tube 11, and the sliding rod 12 drives the positioning plate 8 to reset.

[0038] The two positioning plates 8 move to open, and at the same time the sliding rod 12 moves and drives the lifting plate 5 to move and reset. Figure 6 The connecting rods 23 corresponding to different positioning connecting blocks 17 in a single set of lifting plates 5 have different relative heights to the connecting blocks 17, and the smaller the silicon steel sheet 6 pile, the smaller the distance between the adjusting rod 24 and the top of the connecting block 17. Therefore, during the rising process of the connecting block 17, the adjusting rods 24 corresponding to silicon steel sheets 6 of different specifications drive the moving distances of the No. 2 rack 22 to be different, so that the horizontal moving distance of the two corresponding positioning plates 8 after the silicon steel sheets 6 of different specifications move up the rated distance is adapted to the size of the lifting plate 5.

[0039] The No. 1 telescopic mechanism 18 adjusts the height of the lifting plate 5 while adjusting the spacing of the positioning plates 8 to reduce energy consumption. The number of silicon steel sheets 6 corresponding to a single lifting plate 5 is greater than that required for stacking a single iron core. The distance sensor 26 is used to detect the thickness of each level of the iron core. After the silicon steel sheets 6 are stacked, the layer thickness fluctuates and the thickness is too small. The silicon steel sheets 6 can continue to be absorbed from the lifting plate 5, and when the layer thickness of the iron core is about to exceed the rated range, the lifting plate 5 is directly switched to avoid the presence of silicon steel sheets 6 of different specifications in a single silicon steel sheet 6 pile. The rated number of silicon steel sheets 6 at each level makes it difficult to adjust according to the actual stacking thickness of the iron core, and it is necessary to stop and calibrate. Therefore, the iron chip stacking device ensures that the shape of the cross-section of the stacked iron core column meets the requirements.

Various modifications to these embodiments will be readily apparent to one skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention.
