Description

Technical Field

[0001] The utility model relates to the technical field of magnetic component separation, and particularly relates to a device for separating a magnetic component from a steel sheet. Background Art

[0002] Magnetic component products include magnetic components and steel sheets. The magnetic components are composed of multiple magnetic sheets combined in a certain arrangement. The magnetic components are adhered to the top side of the steel sheet by glue. Since there are precision requirements for the specific fixing position of the magnetic components on the steel sheet in the assembled magnetic component products, magnetic component products that do not meet the precision requirements are unqualified products. If rework is required, the magnetic components need to be separated from the steel sheet. However, in the prior art, when separating the magnetic components from the steel sheet, it is easy to damage the bonding between the magnetic sheets, resulting in unqualified products being scrapped, and thus this case arises. Content of the Utility Model

[0003] The purpose of the utility model is to provide a device for separating a magnetic component from a steel sheet, to solve the above technical problems, which can facilitate the separation of the magnetic component from the steel sheet and will not damage the adhesion between the magnetic sheets.

[0004] To achieve the above purpose, the solution of the utility model is: a device for separating a magnetic component from a steel sheet, which is used to separate the magnetic component from the steel sheet on a magnetic component product. The magnetic component is fixed in the middle of the top side of the steel sheet, and includes a lower die component, an upper die component and at least one cutter component;

[0005] The lower die component is located below the upper die component. The top side of the lower die component has a placement table for placing the magnetic component product. When the magnetic component product is placed, the bottom side of the steel sheet is fixed to the placement table, and the side edge of the steel sheet extends out of the placement table;

[0006] The upper die component moves up and down, approaching or moving away from the lower die component. The bottom side of the upper die component has a pressing head. The upper die component can drive the pressing head to descend, so that the pressing head presses the side edge of the steel sheet until the side edge of the steel sheet bends away from the magnetic component;

[0007] The cutter component is located on the side of the lower die component and on the side where the side edge of the steel sheet is located. The cutter head of the cutter component faces the side edge of the steel sheet and can approach or move away from the steel sheet horizontally. The cutter head is used to insert between the bent steel sheet and the magnetic component.

[0008] Further, the lower die component can slide into or out of the lower part of the upper die component, so as to place or remove the magnetic component product when sliding out of the lower part of the lower die component.

[0009] Further, it further includes a positioning component. When the lower die component slides out from below the upper die component, the positioning component is located on one side of the lower die component and on the side where the side of the steel sheet is located, and can approach or move away from the magnetic component product horizontally. The positioning component faces the steel sheet, and an alignment surface is formed on one side of the side, so that when approaching, the positioning component pushes against the side of the steel sheet to align and position the side of the steel sheet with the alignment surface.

[0010] Further, the placement table protrudes from the top side of the lower die component, so that when the upper die component descends, the pressing head can press down the side of the steel sheet.

[0011] Further still, a concave cavity is provided on the bottom side of the pressing head, so that when the upper die component descends, the placement table falls into the concave cavity, and the side of the steel sheet extends out of the concave cavity.

[0012] Further, the number of the cutter assemblies is two, the cutter heads of the two cutter assemblies are arranged opposite to each other, and are respectively located on both sides of the lower die component. The two opposite sides of the steel sheet respectively extend out of the placement table, and the two cutter heads respectively face the two sides of the steel sheet, and can both approach or move away from the steel sheet horizontally.

[0013] Further, the cutter head is inwardly recessed towards the side of the steel sheet to form a wedge shape, and a cutting edge is formed at the wedge-shaped end, and the cutting edge faces the side of the steel sheet.

[0014] Further still, the cutting edge is inclined, with one end close to the steel sheet and the other end far from the steel sheet.

[0015] Further, two limiting surfaces are formed on the placement table, and the two limiting surfaces are arranged opposite to each other, so that when the magnetic component product is placed on the placement table, the two limiting surfaces respectively limit the two ends of the steel sheet, and the two sides of the steel sheet respectively extend out of the placement table.

[0016] Further, at least one anti-fooling hole is formed by concave-convex on the top side of the placement table, and it further includes an anti-fooling magnet. The anti-fooling magnet is embedded in the anti-fooling hole, so that when the magnetic component product is placed on the placement table, the anti-fooling magnet is used to adsorb the steel sheet to fix the magnetic component product on the placement table.

[0017] After adopting the above scheme, the beneficial effects of the present utility model are as follows: The lower die component is located below the upper die component. When the upper die component descends, it drives the pressing head to press down the side of the steel sheet, so that the steel sheet bends towards the direction away from the magnetic component, and then a tear opening is generated between the steel sheet and the magnetic component. The cutter assembly is arranged on one side of the lower die component and on the side where the side of the steel sheet is located, and the cutter head faces the side of the steel sheet. When approaching the magnetic component product horizontally, the cutter head can be inserted from the tear opening, and then the steel sheet is separated from the magnetic component. The cutter head will not damage the inside of the magnetic component, reduce the generation of magnetic component waste, and reduce the production cost. Description of the Drawings

[0032] As Figures 1 to 10 shown, a device for peeling a magnetic component from a steel sheet is used to separate the magnetic component 101 on the magnetic component product 100 from the steel sheet 102. The magnetic component 101 is fixed in the middle of the top side of the steel sheet 102, and the magnetic component 10 and the steel sheet 102 are adhesively fixed together by glue. It includes a lower die assembly 1, an upper die assembly 2 and at least one cutter assembly 3; in this specific embodiment, it further includes a top plate 6 and a bottom plate 7, and the top plate 6 and the bottom plate 7 are fixedly connected by a support rod 8 to form a tooling frame. The support rod 8 has at least four, which are respectively located around the bottom plate 7 and the top plate 6. The lower die assembly 1, the upper die assembly 2 and the cutter assembly 3 are all arranged in this tooling frame.

[0033] The lower die assembly 1 is located below the upper die assembly 2. The lower die assembly 1 can be fixed below the upper die assembly 2 or can slide into the position below the upper die assembly 2 from other positions, without specific limitation. The top side of the lower die assembly 1 has a placement table 11 for placing the magnetic component product 100. When the magnetic component product 100 is placed, the bottom side of the steel sheet 102 is fixed to the placement table 11, and the side of the steel sheet 102 extends out of the placement table 11; the upper die assembly 2 moves up and down, approaching or moving away from the lower die assembly 1, with key combination Figure 3As shown, the upper die assembly 2 includes a lifting telescopic cylinder 23, which can be any existing telescopic cylinder, such as a telescopic air cylinder or others, without specific limitation. The top end of the lifting telescopic cylinder 23 is fixed to the bottom side of the top plate 6, and the bottom end of the lifting telescopic cylinder 23 is the telescopic end. The bottom side of the upper die assembly 2 has a pressure head 21, and the pressure head 21 is fixed to the telescopic end and moves up and down with the telescopic end. The upper die assembly 2 can drive the pressure head 21 to descend, and the pressure head 21 is used to press down the side of the steel sheet 102 until the side of the steel sheet 102 bends away from the magnetic assembly 101. After the side of the steel sheet 102 bends, a tear opening can be formed between the steel sheet 102 and the magnetic assembly 101; the cutting tool assembly 3 is located on one side of the lower die assembly 1 and on the side where the side of the steel sheet 102 is located. The cutting head 31 of the cutting tool assembly 3 faces the side of the steel sheet 102 and can approach or move away from the steel sheet 102 horizontally. After the side of the steel sheet 102 bends, the cutting tool assembly 3 approaches horizontally, and the cutting head 31 is used to insert between the bent steel sheet 102 and the magnetic assembly 101, that is, insert from the tear opening and continue to insert to separate the magnetic assembly 101 and the steel sheet 102. Specifically, the cutting tool assembly 3 further includes a tool holder 34 and a cutting tool telescopic cylinder 35. The cutting tool telescopic cylinder 35 can be any existing telescopic cylinder, such as a telescopic air cylinder or others, without limitation here. The cutting head 31 is fixed on the tool holder 34, and the tool holder 34 is fixedly connected to the telescopic end of the cutting tool telescopic cylinder 35. The telescopic end of the cutting tool telescopic cylinder 35 extends and retracts to drive the tool holder 34 to drive the cutting head 31 to approach or move away from the magnetic assembly product 100 on the placement table 11 horizontally.

[0034] Focusing on Figure 2 As shown, the number of the cutting tool assemblies 3 is two. The cutting heads 31 of the two cutting tool assemblies 3 are arranged oppositely and are respectively located on both sides of the lower die assembly 1. The two opposite sides of the steel sheet 102 respectively extend out of the placement table 11. The two cutting heads 31 respectively face the two sides of the steel sheet 102 and can both approach or move away from the steel sheet 102 horizontally. The two cutting tool assemblies 3 can approach the steel sheet 102 horizontally at the same time, or one cutting tool assembly 3 can approach the steel sheet 102 first and then the other approaches, and then separation is carried out.

[0035] Focusing on as shown in 9, the cutting head 31 is inwardly retracted towards the side of the steel sheet 102 to form a wedge 32, and a cutting edge 33 is formed at the end of the wedge 32. The cutting edge 33 faces the side of the steel sheet 102. Focusing on Figure 10 From a top view, the cutting edge 33 is inclined, with one end close to the steel sheet 102 and the other end far from the steel sheet 102. When the cutting edge 33 gradually approaches the magnetic assembly product 100, one end of the cutting edge 33 first approaches the steel sheet 102. When inserting, the cutting edge 33 is in point contact with the tear opening, which is convenient for cutting in from the tear opening and will not cause damage to the magnetic assembly 102 itself. As the cutting edge 33 is gradually inserted, the steel sheet 102 is peeled off from the magnetic assembly product 100, and then the magnetic assembly 101 and the steel sheet 102 are separated.

[0036] Focusing onFigure 1 and Figure 2 As shown, the lower die assembly 1 can slide into or out from under the upper die assembly 2. When sliding out from under the lower die assembly 1, the magnetic component product 100 can be placed or removed. That is, the loading process and the separation process are completed at different stations, which can effectively ensure the safety of the loading operation. Specifically, the lower die assembly 1 further includes a lower die 14, a slider 15, a slide rail 16, and a transfer telescopic cylinder 17. The slide rail 16 is fixed on the bottom plate 7 in the front-rear direction. The slider 15 is slidably arranged on the slide rail 16 in the front-rear direction. The slider 15 is connected to the transfer telescopic cylinder 17. The transfer telescopic cylinder 17 is fixed on the bottom plate 7, and its telescopic end is fixedly connected to the slider 15. The telescopic end of the transfer telescopic cylinder 17 expands and contracts to drive the slider 15 to slide back and forth. The transfer telescopic cylinder 17 can be any existing telescopic cylinder, such as a telescopic air cylinder or others, which is not limited here. The lower die 14 is fixed on the top side of the slider 15 and slides back and forth with the slider 15. When the lower slider 15 slides backward, it can drive the lower die 14 to slide under the upper die assembly 2. When the slider 15 slides forward, it can drive the lower die 14 to slide out from under the die assembly 2 and away from the lower die assembly 2. Furthermore, the opposite two sides of the steel sheet 102 are located on the opposite two sides in the front-rear direction.

[0037] Focusing on again in combination with Figure 1 As shown, it further includes a positioning component 4. When the lower die assembly 1 slides out from under the upper die assembly 2, the positioning component 4 is located on one side of the lower die assembly 1 and on the side where the side of the steel sheet 102 is located. It can approach or move away from the magnetic component product 100 horizontally. An alignment surface 41 is formed on the side of the positioning component 4 facing the side of the steel sheet 102. When approaching, the positioning component 4 abuts against the side of the steel sheet 102, so that the side of the steel sheet 102 is aligned with the alignment surface 41 for alignment positioning, so as to adjust the placement position of the magnetic component product 100 and complete the positioning of the magnetic component product 100. Specifically, the positioning component 4 includes a positioning block 42 and a positioning telescopic cylinder 43. The alignment surface 41 is formed on the positioning block 42. The positioning telescopic cylinder 43 is fixed on the bottom plate 7. The positioning telescopic cylinder 43 can be any existing telescopic cylinder, such as a telescopic air cylinder or others, which is not limited here. The positioning block 42 is fixed on the telescopic end of the positioning telescopic cylinder 43, approaches the placement table 11 as the telescopic end extends, and moves away from the placement table 11 as the telescopic end retracts. In this specific embodiment, the number of the positioning components 4 is two, which are respectively located on both sides of the lower die assembly 1, that is, on the left and right sides of the lower die assembly 1. The two alignment surfaces 42 of the two positioning blocks 42 are arranged oppositely and both face the side of the steel sheet 102, so as to push against from the opposite two sides of the steel sheet 102 when approaching the placement table 11, so that the two opposite sides of the steel sheet 102 are respectively aligned with the two alignment surfaces 41 for alignment positioning.

[0038] Focusing on in combination with Figure 3As shown, the placement table 11 protrudes from the top side of the lower die assembly 1 so that when the upper die assembly 2 descends, the pressing head 21 can press down the sides of the steel sheet 102. Specifically, the opposite sides of the steel sheet 102 both extend out of the placement table 11 respectively. The pressing head 21 can be composed of two pressing heads 21, which are respectively located above the two sides of the steel sheet 102 and can press down the two sides of the steel sheet 102 respectively. It can also be that at least two or more pressing heads 21 correspond to each side of the steel sheet 102, and the pressing is more uniform. Of course, the pressing head 21 can also be of other structures; Focusing on combining Figure 5 As shown, in this specific embodiment, a concave cavity 22 is provided on the bottom side of the pressing head 21 so that when the upper die assembly 2 descends, the placement table 11 falls into the concave cavity 22, and the sides of the steel sheet 102 extend out of the concave cavity 22, and the lower bottom surface of the pressing head 21 can press down the two sides of the steel sheet 102 respectively.

[0039] Focusing on combining Figure 8, two limiting surfaces 12 are formed on the placement table 11. The two limiting surfaces 12 are arranged oppositely in the front-back direction and respectively limit the two ends of the steel sheet 102. When placing the magnetic component product 100, the two ends of the steel sheet 102 are respectively opposite to the two limiting surfaces 12, so that the two opposite sides of the steel sheet 102 extend out of the placement table 11, which can facilitate the positioning and placement of the magnetic component product 100.

[0040] At least one anti-fooling hole 13 is formed by the top side of the placement table 11 being recessed downward. An anti-fooling magnet 5 is also included. The anti-fooling magnet 5 is embedded in the anti-fooling hole 13 so that when the magnetic component product 100 is placed on the placement table 11, the anti-fooling magnet 5 is used to adsorb the steel sheet 102 to fix the magnetic component product 100 on the placement table 11.

[0041] Working process:

[0042] In the initial state, the lower die assembly 1 is aligned with the positioning assembly 4. First, the magnetic component product 100 is placed on the placement table 11, and the positioning telescopic cylinder 43 acts to drive the positioning block 42 to horizontally approach the magnetic component product 100 (as Figure 4 shown), adjust the position of the magnetic component product 100, the positioning telescopic cylinder 43 drives the positioning block 42 to reset, the transfer telescopic cylinder 17 acts to drive the lower die assembly 1 to slide under the upper die assembly 2, the lifting telescopic cylinder 23 acts to drive the pressing head 21 to descend and press down the sides of the steel sheet 102 (as Figure 5 shown), so that a tear opening is formed between the steel sheet 102 and the magnetic component 101. The lifting telescopic cylinder 23 drives the pressing head 21 to rise and reset. The cutter telescopic cylinder 35 drives the cutter head 31 to horizontally approach the magnetic component product 100, and the cutting edge 33 is inserted into the tear opening (as Figure 6As shown, insert along the tear opening to separate the steel sheet 102 from the magnetic component 101. The cutter telescopic cylinder 35 drives the cutter head 31 away from the magnetic component product 100 and resets. The transfer telescopic cylinder 17 drives the lower die assembly 1 to slide out from below the upper die assembly 2 and resets to align with the positioning component 4, completing one separation of the steel sheet 102 from the magnetic component 101.

[0043] The above are only the preferred embodiments of the present utility model and do not limit the design of this case. All equivalent changes made according to the key design of this case fall within the protection scope of this case.
