Description

Technical Field

[0001] This utility model relates to the field of magnetic core manufacturing and processing, and in particular to a conveying mechanism for unloading magnetic cores. Background Technology

[0002] A magnetic core is a sintered magnetic metal oxide composed of various iron oxide mixtures. For example, manganese-zinc ferrite and nickel-zinc ferrite are typical core materials. Manganese-zinc ferrite features high permeability and high flux density, along with low losses. Nickel-zinc ferrite exhibits extremely high impedance and low permeability (less than a few hundred). Ferrite cores are used in coils and transformers in various electronic devices.

[0003] After ferrite powder is pressed into magnetic cores, the cores are transported in batches to the feeding area on the workbench. Each batch of cores is kept in a specific quantity. After each batch of cores is neatly arranged in the feeding area, it is placed on a material plate. Then, the workers take the cores to the sintering device through the material plate for sintering, which makes the ferrite powder bond more tightly, thus making the cores stronger. Usually, the workers first take the material plate to the feeding area on the workbench, wait for the cores to be processed, and after they are neatly arranged and placed on the material plate, the workers take the material plate with the cores to the sintering device and place an empty material plate in the feeding area. Therefore, the workers need to wait for a period of time after placing each material plate before they can take the next material plate to the workbench. During this time, there is not enough time to do other work, thus increasing the workers' downtime. Utility Model Content

[0004] The purpose of this invention is to provide a conveying mechanism for feeding magnetic cores, thereby solving the aforementioned problems.

[0005] The above-mentioned technical objective of this utility model is achieved through the following technical solution: A conveying mechanism for feeding magnetic cores includes a base, a support frame fixedly connected to the rear of the base, the top of the support frame being higher than the upper surface of the base, guide rods fixedly connected to the bottom two sides of the support frame, and a placement frame located inside the support frame, between the two guide rods. The two sides of the support frame are slidably connected to the two guide rods respectively. Multiple support plates are fixedly connected to the inner sidewalls of the placement frame, each support plate including two support bars. The two support bars of the same layer are fixedly connected to the two sides of the placement frame, with a gap between them. A material plate is placed on the upper part between the two support bars of the same layer. A lifting mechanism is provided at the bottom of the support frame, connected to the placement frame. A feeding mechanism is provided on the other side of the base opposite to the support frame. A conveying mechanism is provided on the upper part of the base, passing through the feeding mechanism and the support frame, and passing between the support bars on both sides of the placement frame.

[0006] Using the above technical solution, the conveying mechanism is initially positioned below the bottom material plate of the placement frame. Cylinder 1 lowers the placement frame, which in turn lowers the material plate and support bars. The bottom material plate descends until it contacts the conveying mechanism. The placement frame and support bars continue to descend, separating the bottom material plate from its support bars. The conveying mechanism then starts, causing the material plate above it to leave the support frame. The material plate on the conveying mechanism moves to the unloading area near the workbench. A batch of pressed and neatly arranged magnetic cores is placed on the material plate of the conveying mechanism via a moving device. Once the material plate is full of magnetic cores, the conveying mechanism transports the material plate and magnetic cores to the unloading mechanism. After the second batch of magnetic cores is pressed, the lifting mechanism lowers the placement frame again, causing the material plate on the second-to-last layer of the placement frame to fall onto the conveying mechanism. The conveyor mechanism then transports the upper material plates to the feeding area near the worktable. After the magnetic cores are placed on the material plates, the material plates and magnetic cores are transported to the unloading mechanism. This process continues sequentially, with all the material plates in support frame one being transported to the unloading mechanism and filled with magnetic cores. Then, the lifting mechanism raises placement frame one back to its original position. Magnetic cores continue to be pressed in the magnetic core pressing area, and the pressed magnetic cores are arranged neatly. Simultaneously, a material plate is placed on top of the two support bars in each layer of placement frame one. The magnetic cores placed on the material plates in the unloading mechanism are then taken to the sintering area for sintering. Workers no longer need to wait for a period of time after each material plate is placed before taking the next one to the worktable. While the magnetic cores are being placed on each material plate in placement frame one, workers can perform other tasks. Workers only need to place new material plates after all the material plates in placement frame one have been transported to the unloading mechanism and take the material plates with magnetic cores from the unloading mechanism to the sintering area, concentrating their time to better complete other tasks.

[0007] Preferably, the connector includes guide rods and connecting pieces. There are two guide rods, which are vertically fixed to the bottom sides of the support frame. Connecting pieces are fixedly connected to both sides of the placement frame. The placement frame is located between the two guide rods. The two guide rods pass through the connecting pieces on both sides of the placement frame and are slidably connected to the connecting pieces on both sides of the placement frame.

[0008] Using the above technical solution, the lifting mechanism drives the support frame to move vertically along the guide rod. The guide rod guides and limits the movement of the support frame, increasing the stability of the support frame's movement.

[0009] Preferably, the conveying mechanism includes a support base, a timing belt, and timing pulleys. The support base includes two mounting bars, which are fixedly connected to the base. A connecting bar is fixedly connected between the two mounting bars, and the mounting bars pass through the support frame and the feeding mechanism. It also includes two rotating shafts, which are located at both ends of the support base. Each rotating shaft passes through the two mounting bars, and timing pulleys are fixedly connected to both ends of the rotating shafts. A timing belt is connected between the two timing pulleys located on the same side of the support base.

[0010] Using the above technical solution, the drive mechanism drives the synchronous pulley connected to it to rotate, the rotating synchronous pulley drives another synchronous pulley located on the same rotating shaft to rotate, and the two rotating synchronous pulleys then drive two synchronous pulleys on another rotating shaft to rotate through the synchronous belt.

[0011] Preferably, the system also includes a mounting base located at the front of the base. The upper part of the mounting base is fixedly connected to a second support frame with the same structure as the first support frame. The second support frame is equipped with a lifting mechanism identical to that in the first support frame and a second placement frame identical to the first placement frame. The second placement frame is equipped with a support bar identical to that in the first placement frame, and the conveying mechanism passes through the interior of the second support frame.

[0012] Using the above technical solution, the conveying mechanism passes between the two uppermost support bars in the placement frame two of the support frame two. The conveying mechanism transports the material plate with the magnetic core to the area above the two uppermost support bars of the support frame two. The lifting mechanism drives the placement frame two to rise, and the placement frame two drives the support bars inside it to rise. The two uppermost support bars push the material plate with the magnetic core on the conveying mechanism to rise and leave the conveying mechanism, so that the material plate is placed on the two support bars. At the same time, the rise of the placement frame two makes the upper surface of the conveying mechanism located between the two support bars of the uppermost and second layers of the placement frame two. The conveying mechanism then transports the material plate with the magnetic core to the upper part of the two support bars of the second layer in the placement frame two. The lifting mechanism drives the placement frame two to rise again, and the support bars of the second layer push the material plate with the magnetic core off the conveying mechanism. The material is located on the two support bars of the second layer. At the same time, the upper surface of the conveying mechanism is located between the two support bars of the second and third layers of the placement frame two. Material plates are placed on each support bar of the placement frame two in sequence.

[0013] Preferably, the lifting mechanism on the support frame is a cylinder, which is vertically fixedly connected to the bottom outer side of the support frame, and the output shaft of the cylinder is fixedly connected to the bottom of the placement frame.

[0014] Using the above technical solution, the cylinder's output shaft extends or retracts to push the placement frame to rise or fall.

[0015] Preferably, the lifting mechanism on the second support frame is a second cylinder, which is vertically fixedly connected to the outer side of the bottom of the second support frame, and the output shaft of the second cylinder is fixedly connected to the bottom of the second placement frame.

[0016] Using the above technical solution, the output shaft of cylinder two extends or retracts to push the placement frame two up or down. Attached Figure Description

[0020] See Figure 1 , Figure 2 A conveying mechanism for feeding magnetic cores includes a base 1, a support frame 2 fixedly connected to the rear of the base 1, the top of the support frame 2 being higher than the upper surface of the base 1, and vertical guide rods 6 fixedly connected to both sides of the bottom of the support frame 2. It also includes a placement frame 3 located inside the support frame 2 and between the two guide rods 6. Connecting pieces 7 are fixedly connected to both sides of the placement frame 3, and the two guide rods 6 pass through the connecting pieces 7 on both sides of the placement frame 3, with the connecting pieces 7 slidably connected to the guide rods 6.

[0021] See Figures 3 to 8 The inner sidewall of the placement frame 3 is fixedly connected to multiple layers of support plates. Each layer of support plate includes two support bars 4. The two support bars 4 of the same layer are fixedly connected to both sides of the placement frame 3, and there is a gap between the two support bars 4 of the same layer. A material plate 5 is placed on the upper part between the two support bars 4 of the same layer. A vertical cylinder 14 is fixedly connected to the outer bottom of the support frame 2. The output shaft of the cylinder 14 is fixedly connected to the bottom of the placement frame 3. A mounting seat 11 is provided at the front of the base 1. A support frame 2 12 with the same structure as the support frame 2 is fixedly connected to the upper part of the mounting seat 11. The support frame 2 12 is equipped with a cylinder 2 15 and a placement frame 2 13, which are the same as the cylinder 14 and placement frame 3 located inside the support frame 2. The support bars 4 are the same as those in the placement frame 3.

[0022] See Figure 1 , Figures 5 to 8A support base 8 is fixedly connected to the base 1, located between support frame 1 (2) and support frame 2 (12), and passes through both support frames 1 and 2. The support base 8 includes two mounting rods fixedly connected to the base 1, with a connecting rod fixedly connected between them. It also includes two rotating shafts located at opposite ends of the support base 8, each passing through the two mounting rods. Synchronous pulleys 10 are fixedly connected to both ends of each shaft. A synchronous belt 9 connects the two synchronous pulleys 10 located on the same side of the support base 8 but not on the same shaft. A motor is mounted on the support base 8, and the motor output shaft is fixedly connected to one of the synchronous pulleys 10 on the conveyor belt. One end of the mounting rod passes through the support bars 4 on both sides inside the placement frame 1 (3), and the other end of the mounting rod passes through the support bars 4 on both sides inside the placement frame 1 (3).

[0023] Working principle: The portion of the conveyor belt that enters support frame 12 is initially positioned below the bottom material plate 5 of placement frame 13, while the portion that enters support frame 212 is positioned between the two top support bars 4 of placement frame 213. Cylinder 14 drives placement frame 13 to descend along guide rod 6, which in turn drives material plate 5 and support bars 4 to descend. The bottom material plate 5 descends until it contacts the synchronous belt 9 of the conveyor belt. Placement frame 13 and support bars 4 continue to descend, thereby separating the bottom material plate 5 from the support bar 4 it is on. The motor on support base 8 drives the synchronous pulley 10 connected to it to rotate, and the conveyor belt starts, causing the material plate 5 above it to leave support frame 12. The material plate 5 on the conveyor belt moves to the feeding area near the workbench. A batch of pressed and neatly arranged magnetic cores are placed on the material plate 5 on the conveyor belt by a moving device. After the material plate 5 is full of magnetic cores, the conveyor belt transports the material plate 5 and magnetic cores to the placement frame 13 of the support frame 12. The material plate 5 on the conveyor belt is located above the two uppermost support bars 4 of the support frame 12. The cylinder 15 pushes the placement frame 13 to rise, which in turn drives the support bars 4 inside the placement frame 13 to rise. The two uppermost support bars 4 push the material plate 5 containing the magnetic cores on the conveyor belt to rise away from the synchronous belt 9 of the conveyor belt, so that the material plate 5 is placed on the two support bars 4. At the same time, the rise of the placement frame 13 causes the upper surface of the synchronous wheel 10 of the conveyor belt to be located between the two layers of support bars 4 of the uppermost and second layers of the placement frame 13.

[0024] After the second batch of magnetic cores is pressed, cylinder 14 lowers the placement frame 3 again, causing the material plate 5 on the second-to-last layer of placement frame 3 to fall onto the synchronous pulley 10 of the conveyor belt. The conveyor belt then transports the upper part of the material plate 5 to the unloading area near the workbench. After the magnetic cores are placed on the material plate 5, the conveyor belt transports the material plate 5 with magnetic cores to the two support bars 4 of the second layer in placement frame 13. Cylinder 2 15 then raises placement frame 13 again, and the support bars 4 of the second layer of placement frame 13 push the material plate 5 with magnetic cores off the conveyor belt. The material is now located on the two support bars 4 of the second layer, and the upper surface of the conveyor belt is located between the two support bars 4 of the second and third layers of placement frame 13. This process continues, with the material plates 5 in support frame 2 being transported to support frame 12 and filled with magnetic cores.

[0025] Then, cylinder 14 drives placement frame 3 to rise back to its original position, and the magnetic cores continue to be pressed in the core pressing area, arranging the pressed cores neatly. Simultaneously, a material plate 5 is placed on the upper part between the two support bars 4 of each layer in placement frame 3, and the magnetic cores placed on the material plates 5 in placement frame 2 are taken to the sintering area for sintering. Cylinder 2 15 drives placement frame 2 13 to descend back to its original position. Workers no longer need to wait for a period of time after placing each material plate 5 before taking the next material plate 5 to the worktable; while placing magnetic cores on each material plate 5 in placement frame 3, workers can perform other tasks. Workers only need to place new material plates 5 after all the material plates 5 in placement frame 3 have been conveyed to the unloading mechanism, and then take the material plates 5 with magnetic cores from the unloading mechanism to the sintering area, concentrating their time to better complete other tasks.
