Abstract
Description
Technical Field
[0001] This application relates to the field of electromagnetic technology, specifically to a core separation device for laminating iron cores. Background Technology
[0002] Transformers are key equipment for converting and transmitting electrical energy. Their internal core is usually made up of multiple stacked silicon steel sheets. During the core lamination process, chucks are often used to alternately pick up two or more different specifications of core sheets, and a complete large core is formed by stacking them layer by layer.
[0003] However, in practice, existing technologies have significant drawbacks. When a chuck picks up a sheet-like iron core, due to the adsorption and friction forces on the surface of the silicon steel sheets, the next layer of silicon steel sheets easily adheres to the chuck as it lifts the target iron core, leading to overlapping. This overlapping phenomenon results in two iron cores being retrieved in a single operation, severely impacting the accuracy and efficiency of iron core lamination. It can also cause dimensional deviations and magnetic instability in subsequent iron core assembly, ultimately affecting the overall performance and lifespan of the transformer. Therefore, there is an urgent need for equipment that can effectively avoid overlapping in iron core lamination operations to meet the stringent requirements for quality and efficiency in transformer manufacturing. Utility Model Content
[0004] In view of the above problems, this application provides a core separation device to solve the technical problem of repeated core removal during the process.
[0005] To achieve the above objectives, this application provides a core separation device for stacking cores to be stacked on a core stacking machine, the core separation device comprising:
[0006] A substrate is disposed on a core stacking machine, the cores are stacked on the substrate, and the upper surface of the substrate is provided with multiple grooves;
[0007] Multiple fixing posts are vertically arranged on the slide groove and abut against the side of the iron core to limit the position of the iron core on the substrate;
[0008] Multiple magnetic pillars are vertically and adjustablely positioned on the slide groove, spaced apart from the side of the iron core, to attract the iron core upward by the generated magnetic force, causing at least the top layer of the iron core to move partially or entirely upward, so that air can enter the lower surface of the top layer of the iron core.
[0009] Furthermore, the upper part of the magnetic column is a rectangular column or a cylindrical column, and the bottom of the magnetic column is provided with a sliding part that slides with the slide groove, and the end of the sliding part is provided with a locking nut to lock the position of the magnetic column in the slide groove.
[0010] Furthermore, a corresponding fixing post is provided on the side of each magnetic post; a gap is left between the magnetic post and the corresponding fixing post.
[0011] Furthermore, the number of magnetic pillars provided on the first side of the substrate is greater than the number of magnetic pillars provided on the second side opposite to the first side, causing the topmost iron core to move upward at a local position corresponding to the first side.
[0012] Furthermore, the magnetic force causes at least two or more of the iron cores on the top of the substrate to partially move upward and separate from each other.
[0013] Furthermore, the fixing post is slidably disposed within the groove, and the height of the fixing post is greater than the height of the magnetic post.
[0014] Furthermore, the slide groove includes a transverse slide groove extending laterally along the substrate and a longitudinal slide groove extending longitudinally along the substrate.
[0015] Furthermore, the magnetic column is made of any one or more strongly magnetic materials selected from neodymium iron boron, samarium cobalt, alnico, and iron chromium cobalt.
[0016] Unlike existing technologies, the above-mentioned iron core separation device has multiple magnetic pillars on the substrate of the stacked iron cores. The magnetic pillars are located on the side of the iron cores and are set in the grooves on the surface of the substrate. The number and position of the magnetic pillars can be set as needed, so that the upward magnetic force generated by the magnetic pillars will move at least one iron core on the top layer partially or entirely upward. This allows air to enter between two adjacent stacked iron cores, avoiding the re-lamination of the iron cores due to the surface adsorption force between the iron cores when the suction cup picks up the material, thus improving the quality and efficiency of iron core stacking.

[0036] Please see Figures 1 to 5 This embodiment provides a core separation device 1. This core separation device 1 is applied to... Figure 1 The iron core stacking machine shown is used to stack iron cores to be stacked. The iron cores are usually silicon steel sheets, i.e. sheet-shaped silicon steel.
[0037] like Figure 1 The diagram shows the structure of the core laminating machine. The core laminating machine includes a support frame and a stacking gripper 5 mounted on the support frame. Two parallel longitudinal tracks 3 are mounted on the support frame, and a gantry frame 6 is mounted on the two longitudinal tracks 3. A transverse track 2 is mounted on the gantry frame 6. The stacking gripper 5 is movably mounted on the transverse track 2 and is driven to move along the transverse track 2 by a transverse motor 21. Figure 1 As shown, the lower part of the stacking gripper 5 is provided with an extension rod, and the end of the extension rod is provided with a suction cup 51 for adsorbing the iron core 20. The extension rod allows the suction cup 51 to reach the bottom of the iron core separation device 1 to adsorb the iron core.
[0038] The central part of the iron core stacking machine is the iron core stacking area, which is the area where iron core stacking operations are performed. A stacking support plate 4 is installed below the stacking area. Stacking grippers 5 grab the iron cores 20 from the iron core separation devices 1 on both sides of the iron core stacking machine and stack them onto the stacking support plate 4. Multiple iron core separation devices 1 are installed on both sides of the iron core stacking machine. Each iron core separation device 1 holds two or more iron cores of different shapes. The stacking grippers 5 alternately grab different iron cores and stack them onto the stacking support plate 4, thereby forming a closed iron core body. When a predetermined number of iron cores have been stacked, the stacking support plate 4 is detached from the iron core stacking machine. Then, a clamp removes the stacking support plate 4 along with the iron cores on it. An empty stacking support plate 4 is then inserted into the stacking area for iron core stacking operations. In this embodiment, the iron core separation device 1 provides multiple magnetic pillars 10 on the substrate 11 of stacked iron cores. The upward magnetic force generated by the magnetic pillars 10 attracts the iron cores 20, thereby causing the topmost iron core 20 (the iron core that is about to be picked up by the suction cup 51) to move up a certain distance, either partially or entirely, so that there is a gap between it and the next iron core 20. Air can enter between the two iron cores, thus eliminating the surface adsorption force between the iron cores and avoiding the phenomenon of overlapping pieces when picking up materials.
[0039] like Figure 2 As shown, in this embodiment, the core separation device includes: a base plate 11, multiple fixing posts 13, and multiple magnetic posts 10. The base plate 11 is disposed on a core stacking machine, specifically on both sides of the stacking area of the core stacking machine. The cores are stacked on the base plate 11, and the upper surface of the base plate 11 is provided with multiple sliding grooves 12. Figure 2 As shown, multiple transverse grooves 121 and multiple longitudinal grooves 122 can be provided on the upper surface of the substrate 11. The multiple transverse grooves 121 are parallel to each other, and the longitudinal grooves 122 are parallel to the transverse grooves 121 but do not intersect.
[0040] like Figure 2 and Figure 3 As shown, multiple fixing posts 13 are vertically arranged on the slide groove 12, specifically on either the transverse slide groove 121 or the longitudinal slide groove 122. The fixing posts 13 abut against the side of the iron core, thus limiting the position of the iron core on the base plate 11. Each fixing post 13 abuts against the side of the iron core at different locations (some fixing posts 13 have a small gap with the side of the iron core for easy material handling). The number and position of the fixing posts 13 can be adjusted according to the shape and size of the iron core. The fixing posts 13 can be made of high-strength components such as steel, aluminum, or aluminum alloy. The bottom of the fixing post 13 can be slidably connected to the slide groove 12 within the slide groove 12, thus allowing the position of the fixing post 13 to be adjusted as needed.
[0041] like Figure 2 and Figure 3 As shown, multiple magnetic pillars are vertically arranged on the upper surface of the substrate 11, and the bottom of the magnetic pillars is adjustablely positioned on the groove 12. Each magnetic pillar is spaced apart from the side of the iron core. The magnetic pillar 10 is used to attract the iron core upwards through the generated magnetic force, thereby causing at least the topmost iron core on the substrate 11 to move partially or entirely upwards. After the iron core moves upwards, air can enter the lower surface of the topmost iron core. This avoids the topmost iron core from sticking to the iron core of the next layer, thus preventing overlapping during material removal (i.e., removing two iron cores at once). When the topmost iron core is removed, the iron core that was originally the second-to-last layer becomes the topmost iron core, and since its upper surface is not pressed against the iron core, it also moves upwards under the action of magnetic force to separate from the iron core of the next layer. The magnetic pillars can be made of any one or more strongly magnetic materials selected from neodymium iron boron, samarium cobalt, alnico, and iron chromium cobalt, thus enabling the magnetic pillars to generate a large magnetic force to attract the iron core upwards.
[0042] In this embodiment, a corresponding magnetic force can be generated by setting the size, number, and position of the magnetic pillars 10. This magnetic force is sufficient to partially move the topmost iron core upwards. Of course, the magnetic force generated by the magnetic pillars can cause at least two or more iron cores at the top of the substrate 11 to partially move upwards and separate from each other. In some embodiments, the magnetic force generated by multiple magnetic pillars is large enough to move the topmost iron core upwards as a whole, thereby completely separating it from the iron cores of the next layer. Or, this large magnetic force can cause two or more layers of iron cores located at the top to partially move upwards.
[0043] like Figure 4 and Figure 5 As shown, the main body 100 of the upper part of the magnetic column is a rectangular or cylindrical column. The bottom of the magnetic column is provided with a sliding part 101 that slidably engages with the sliding groove 12, and a locking nut 103 is provided at the end of the sliding part 101 to lock the magnetic column in the sliding groove 12. Therefore, the sliding part 101 slidably engages with the sliding groove 12, facilitating the adjustment of the magnetic column's position within the groove 12. After the position is adjusted, the magnetic column can be locked and fixed by the locking nut 103. A thread 102 adapted to the locking nut 103 is provided at the end of the sliding part 101. The locking nut 103 is threadedly connected to the sliding part 101. When the locking nut 103 is screwed in from bottom to top, it abuts against the lower surface of the substrate 11, thereby fixing the magnetic column's position within the sliding groove 12. Similar to the magnetic column, the fixing column 13 is also slidably disposed within the sliding groove 12, facilitating the adjustment of the fixing column 13's position. The sliding fit between the bottom of the fixed column 13 and the slide groove 12 adopts the same structure as the bottom of the magnetic column, which will not be described in detail here.
[0044] like Figure 2 , Figure 3 and Figure 4As shown, in this embodiment, a corresponding fixing post 13 is provided on the side of each magnetic post 10; a gap is left between the magnetic post and the corresponding fixing post 13. Furthermore, the height of the fixing post 13 is greater than the height of the magnetic post. In this embodiment, a fixing post 13 is provided on the side of each magnetic post, and the height of the fixing post 13 is greater than the height of the magnetic post. This allows the magnetic post to be protected in both the vertical and horizontal directions by the fixing post 13, preventing the magnetic post from contacting the iron core and breaking.
[0045] like Figure 2 and Figure 3 As shown, in this embodiment, in order to make a portion of the magnet on the top layer of the substrate 11 be attracted upwards by the magnetic pillars, the number of magnetic pillars provided on the first side of the substrate 11 is greater than the number of magnetic pillars provided on the second side opposite to the first side, so that the local position of the top layer iron core corresponding to the first side moves upwards. For example, in this embodiment, Figure 2 The number of magnetic pillars on the rear side of the substrate 11 is significantly greater than the number of magnetic pillars on the front side of the substrate 11, causing the front side of the iron core to move upward locally.
[0046] Finally, it should be noted that although the above embodiments have been described in the text and drawings of this application, this should not limit the scope of patent protection of this application. Any technical solutions that are based on the essential concept of this application and utilize the content described in the text and drawings of this application, resulting in equivalent structural or procedural substitutions or modifications, as well as the direct or indirect application of the technical solutions of the above embodiments to other related technical fields, are all included within the scope of patent protection of this application.
