Description

Technical Field

[0001] The invention relates to the technical field of magnetic core stacking devices, in particular to a high-conductivity ferrite magnetic core stacking and powder spreading device. Background Art

[0002] High-conductivity ferrite cores are made of dense and homogeneous non-metallic magnetic materials with ceramic structures. Compared with other types of magnetic materials, high-conductivity ferrite cores have the advantages of high magnetic permeability, high resistance and low eddy current loss in a wide frequency range.

[0003] High-conductivity ferrite cores are composed of iron oxide and one or more other metal oxides or carbonate compounds; the raw materials need to be sintered at 1300°C after pressing, and finally machined into finished cores that meet application requirements. After high-temperature sintering, the cores need to be stacked and cooled, but direct stacking under high temperature conditions will cause adhesion between the upper and lower layers of the core.

[0009] Furthermore, a vent is provided on the surface of the plug plate, and ventilation springs are symmetrically connected to both sides of the plug plate. The plug plate is elastically connected to the powder box through the ventilation spring, and the ventilation pipe is connected to the inside of the powder box through the vent and the air inlet.

[0010] Furthermore, one end of the ventilation pipe is connected to an air supply pipe, and a cold air outlet is opened on one side of the air supply pipe. One end of the air supply pipe is connected to a blower, and a slide rail is connected to one side of the blower. The slide rail is smoothly connected to a powder sprinkling guide rail close to the blower.

[0011] Furthermore, a bottom frame is connected to one side of the powder sprinkling guide rail away from the slide rail, and a temporary storage groove is provided on the surface of the bottom frame, a receiving spring is connected in the temporary storage groove, and a receiving plate is connected to one end of the receiving spring, the receiving plate is elastically connected to the temporary storage groove through the receiving spring, and the receiving plate is slidably connected to the bottom frame through the temporary storage groove.

[0012] Furthermore, a blocking groove is provided on one side of the temporary storage groove, and a blocking plate is connected in the blocking groove, blocking springs are symmetrically connected on both sides of the blocking plate, a clamping groove is provided on one side of the blocking groove away from the powder spreading guide rail, and a clamping block is slidably connected in the clamping groove, and the clamping block is fixed on the blocking plate.

[0013] Furthermore, a spring hose is provided in the temporary storage groove on the bottom frame away from one end of the powder sprinkling guide rail, and a connecting channel is provided on one side of the spring hose.

[0016] The present invention provides a high-conductivity ferrite core stacking and powdering device, which has the following beneficial effects: when in use, the magnetic cores can be automatically powdered and turned over during the process of conveying the magnetic cores to ensure that the powder can be fully adhered, and the heat can be dissipated before the powdering, and the powdering can be accelerated by airflow, and the powdered magnetic cores can be automatically arranged, and the whole row of magnetic cores can be sucked and stacked after the arrangement is completed.

[0017] 1. When the present invention is in use, when the magnetic core passes through the powder-sprinkling guide rail, the flap can be pushed to rotate in the powder-sprinkling guide rail, so that the flap can apply force to the top block, thereby making the top block slide in the slide groove through its own inclined surface, and then driving the sealing plate to move in the sealing groove and compress the opening and closing spring so that the opening coincides with the nozzle. At this time, the powder pre-loaded in the powder box can be sprayed out of the powder box through the nozzle and sprinkled on the magnetic core. When the magnetic core passes under the flap, the flap can rotate under the action of external force and gravity, and no longer applies force to the top block. The sealing plate can rebound under the action of the opening and closing spring, so that the opening is staggered with the nozzle, so that the sealing plate closes the nozzle to prevent powder leakage. When the magnetic core moves to another powder-sprinkling guide rail through the flipping guide rail, the magnetic core can flip in the flipping guide rail through the spiral structure of the flipping guide rail. The magnetic core is rotated 180° so that the other side of the magnetic core can be sprinkled with powder while it moves on another powder-sprinkling guide rail, ensuring that the powder can fully adhere to the magnetic core and avoiding insufficient powder adhering to the surface of the magnetic core causing the magnetic core to stick to the tray. When conveying magnetic cores of different specifications, the time and distance of the flip plate turning up can automatically change with the change of the magnetic core, thereby automatically controlling the opening and closing time and size of the nozzle without manual adjustment, thereby improving the applicability and convenience of the device. When the magnetic core moves in the powder-sprinkling guide rail, it will be decelerated in the powder-sprinkling guide rail due to the pressure and friction of the flip plate, avoiding damage between the magnetic core and the device due to high-speed impact. In summary, the magnetic core can be automatically sprinkled with powder and flipped during the process of conveying the magnetic core to ensure that the powder can fully adhere.

[0018] 2. When the magnetic core is transported by the present invention, when the magnetic core moves on the slide rail, the blower can transport cold air into the air supply pipe and spray the cold air onto the magnetic core from the cold air outlet to cool the magnetic core, so as to prevent the magnetic core temperature from being too high and affecting the powder sprinkling and stacking. When the magnetic core lifts the flap, the flap can synchronously push the plug plate to slide in the through groove and stretch the ventilation spring so that the vent and the air inlet coincide with each other. At this time, the airflow in the air supply pipe can enter the powder box from the ventilation pipe through the air inlet, increase the air pressure in the powder box, and then accelerate the speed at which the powder in the powder box is sprayed out from the nozzle, thereby improving the powder sprinkling efficiency. After the magnetic core leaves from under the flap, the plug plate can rebound under the action of the ventilation spring, pressurize the flap to make it rotate, and at the same time stagger the vent and the air inlet to prevent the airflow from continuing to enter the powder box. In summary, the magnetic core can be cooled before being sprinkled with powder, so as to ensure the normal progress of the powder sprinkling and stacking processes, and accelerate the powder sprinkling with the help of airflow.

[0019] 3. After the powdering of the magnetic core is completed, the magnetic core of the present invention leaves the powdering guide rail and slides into the bottom frame. After the magnetic core contacts the blocking plate, it will be intercepted by it and stay on the receiving plate. Under the action of the gravity of the magnetic core, the receiving plate is pressed down in the temporary storage groove and compresses the receiving spring, so that the upper surface of the magnetic core is flush with the inner wall of the bottom frame to avoid affecting the sliding of the subsequent magnetic core. When the receiving plate moves down, the card block can be pressed to move down synchronously in the card slot, so that the blocking plate is pressed into the blocking groove and the blocking spring is compressed, and the blocking plate is released to block the next magnetic core, so that the magnetic core is arranged in order in the bottom frame. When the magnetic core reaches the bottom frame away from the powdering guide rail, the magnetic core is arranged in an orderly manner. After reaching one end of the rail, when pressing the receiving plate below, the spring hose can be squeezed synchronously, and the air inside it can be squeezed into the blocking groove of the bottom frame near one end of the powder spreading guide rail through the connecting channel, so that the air pressure lifts the blocking plate in the blocking groove and stretches the blocking spring, so that the blocking plate blocks the subsequent magnetic cores to avoid excess magnetic cores in the bottom frame when the magnetic cores are transported. When conveying different magnetic cores, it is only necessary to place the receiving plate and the receiving spring of the corresponding specifications in the temporary storage groove to adapt to the arrangement of different magnetic cores. When the temporary storage grooves in the bottom frame are all equipped with magnetic cores, the robot arm can move the picking plate into the bottom frame. After the spring switch is pressed onto the blocking plate, the spring switch can energize the electromagnet, so that the electromagnet can adsorb and remove the magnetic core. The receiving plate and the blocking plate in the bottom frame can rebound and reset under the action of the receiving spring and the blocking spring. At the same time, the spring hose can also reset together with the receiving plate. In the process of the receiving plate moving down and rebounding, the air in the temporary storage tank can interact with the outside world through the constant pressure port to ensure that the receiving plate can move normally in the temporary storage tank. Then the robotic arm moves the material taking plate to the tray and puts the adsorbed magnetic core into the material placing tank. The magnetic core can squeeze the airbag, so that the airbag covers and fixes the magnetic core. It can prevent the magnetic core from falling out of the material trough and protect it at the same time. When the spring switch contacts the enclosure, the spring switch can cut off the power to the electromagnet, release the adsorption of the electromagnet to the magnetic core, and leave the magnetic core in the material trough. When the pallet is full of magnetic cores, the empty pallet can be placed on the full pallet. The pallets can be engaged with each other through the enclosure and the enclosure to prevent the pallet from tipping over due to tilted placement. After a certain number of pallets are filled, they can be transported as a whole. In summary, when in use, the magnetic cores that have been powdered can be automatically arranged, and the entire row of magnetic cores can be sucked and stacked after the arrangement is completed.

[0023] See also Figures 1 to 5The sealing plate 209 is elastically connected to the sealing groove 206 through the opening and closing spring 208, and the sealing plate 209 is slidably connected to the powder box 204 through the sealing groove 206. The top block 211 is slidably connected to the powder box 204 through the slide groove 207, and the powder box 204 is connected to the outside through the nozzle 205 and the opening 210. An air inlet 3 is provided on one side of the powder box 204, and a vent pipe 4 is connected to one side of the air inlet 3. A through groove 5 is provided on the side of the vent pipe 4 close to the powder box 204, and a plug plate is slidably connected to the inner side of the through groove 5. 6, a vent 7 is provided on the surface of the plug plate 6, and ventilation springs 8 are symmetrically connected to both sides of the plug plate 6, the plug plate 6 is elastically connected to the powder box 204 through the ventilation springs 8, and the ventilation pipe 4 is connected to the inside of the powder box 204 through the vent 7 and the air inlet 3, one end of the ventilation pipe 4 is connected to an air supply pipe 9, and a cold air outlet 10 is provided on one side of the air supply pipe 9, one end of the air supply pipe 9 is connected to a blower 11, and a slide rail 12 is connected to one side of the blower 11, and the slide rail 12 is smoothly connected to the powder sprinkling guide rail 202 close to the blower 11; The specific operation is as follows. During use, when the magnetic core passes through the powder-spreading guide rail 202, the flap 203 can be pushed to rotate in the powder-spreading guide rail 202, so that the flap 203 applies force to the top block 211, thereby causing the top block 211 to slide in the slide groove 207 through its own inclined surface, thereby driving the sealing plate 209 to move in the sealing groove 206 and compress the opening and closing spring 208, so that the opening 210 coincides with the nozzle 205. At this time, the powder pre-loaded in the powder box 204 can be sprayed out of the powder box 204 through the nozzle 205 and sprinkled on the magnetic core. When the magnetic core passes under the flap 203, the flap 203 can rotate under the action of external force and gravity, and no longer applies force to the top block 211. The sealing plate 209 can be opened and closed by the action of the opening and closing spring 208. The opening 210 and the nozzle 205 are offset by the bottom rebound, so that the sealing plate 209 seals the nozzle 205 to prevent powder leakage. When the magnetic core moves to another powder-sprinkling guide rail 202 through the flipping guide rail 201, the spiral structure of the flipping guide rail 201 allows the magnetic core to flip 180° in the flipping guide rail 201, so that the other side of the magnetic core can be sprinkled with powder when it moves on the other powder-sprinkling guide rail 202, ensuring that the powder can be fully adhered to the magnetic core, avoiding insufficient powder adhered to the surface of the magnetic core causing the magnetic core to stick to the tray 29. When conveying magnetic cores of different specifications, the time and distance of the flip plate 203 turning up can automatically change with the change of the magnetic core, thereby adjusting the opening and closing time of the nozzle 205. The size of the magnetic core can be automatically controlled without manual adjustment, thereby improving the applicability and convenience of the device. When the magnetic core moves in the powder sprinkling guide rail 202, it will be decelerated in the powder sprinkling guide rail 202 due to the pressure and friction of the flap 203, thereby avoiding damage between the magnetic core and the device due to high-speed impact. In summary, the magnetic core can be automatically powdered and flipped during the transportation of the magnetic core to ensure that the powder can be fully adhered. When the magnetic core is transported, when the magnetic core moves on the slide rail 12, the blower 11 can deliver cold air into the air supply pipe 9, and spray the cold air onto the magnetic core from the cold air outlet 10 to cool the magnetic core, thereby avoiding excessive temperature of the magnetic core affecting powder sprinkling and stacking. When the magnetic core lifts the flap 203, The flap 203 can synchronously push the plug plate 6 to slide in the through groove 5 and stretch the ventilation spring 8, so that the vent 7 coincides with the air inlet 3. At this time, the air flow in the air supply pipe 9 can enter the powder box 204 from the ventilation pipe 4 through the air inlet 3, increasing the air pressure in the powder box 204, thereby accelerating the speed at which the powder in the powder box 204 is sprayed out from the nozzle 205, thereby improving the powder sprinkling efficiency. After the magnetic core leaves from under the flap 203, the plug plate 6 can rebound under the action of the ventilation spring 8, pressurizing the flap 203 to make it rotate, and at the same time staggering the vent 7 and the air inlet 3 to prevent the air flow from continuing to enter the powder box 204. In summary, the magnetic core can be cooled before being sprinkled with powder to ensure the normal progress of the powder sprinkling and stacking processes, and the powder sprinkling is accelerated with the help of airflow.

The specific operation is as follows. After the powdering of the magnetic core is completed, the magnetic core leaves the powdering guide rail 202 and slides into the bottom frame 13. After the magnetic core contacts the blocking plate 18, it will be intercepted by it and stay on the receiving plate 16. Under the action of the gravity of the magnetic core, the receiving plate 16 is pressed down in the temporary storage groove 14 and compresses the receiving spring 15, so that the upper surface of the magnetic core is flush with the inner wall of the bottom frame 13 to avoid affecting the sliding of the subsequent magnetic core.

When the magnetic core reaches the bottom frame 13 away from the powdering guide rail 2 02, when pressing the receiving plate 16 below, the spring hose 22 can be squeezed synchronously, and the air inside it can be squeezed into the blocking groove 17 of the bottom frame 13 near one end of the powder spreading guide rail 202 through the connecting channel 23, so that the air pressure lifts the blocking plate 18 in the blocking groove 17 and stretches the blocking spring 19, so that the blocking plate 18 blocks the subsequent magnetic cores to avoid the existence of excess magnetic cores in the bottom frame 13 when the magnetic cores are transported, and when conveying different magnetic cores, it is only necessary to place the receiving plate 16 and the receiving spring 15 of the corresponding specifications in the temporary storage groove 14 to adapt to the arrangement of different magnetic cores. When the temporary storage grooves 14 in the bottom frame 13 are all equipped with magnetic cores, the robot arm 25 can move the material taking plate 26 into the bottom frame 13, When the spring switch 28 is pressed onto the blocking plate 18, the spring switch 28 can energize the electromagnet 27, so that the electromagnet 27 can adsorb and take out the magnetic core, and the receiving plate 16 and the blocking plate 18 in the bottom frame 13 can rebound and reset under the action of the receiving spring 15 and the blocking spring 19, and the spring hose 22 can also be reset together with the receiving plate 16, and in the process of the receiving plate 16 moving down and rebounding, the air in the temporary storage tank 14 can interact with the outside world through the constant pressure port 24, so as to ensure that the receiving plate 16 can move normally in the temporary storage tank 14, and then the robot 25 moves the material taking plate 26 to the tray 29, and puts the adsorbed magnetic core into the material placing tank 30, and the magnetic core can squeeze the airbag 31, so that the airbag 31 can press the magnetic core. The magnetic cores are wrapped and fixed to prevent them from escaping from the material trough 30 and to protect them at the same time. When the spring switch 28 contacts the enclosure 33, the spring switch 28 can cut off the power to the electromagnet 27, release the adsorption of the magnetic core by the electromagnet 27, and leave the magnetic core in the material trough 30. When the tray 29 is full of magnetic cores, the empty tray 29 can be placed on the full tray 29. The trays 29 can be engaged with each other through the enclosure 33 and the enclosure trough 32 to prevent the tray 29 from being tilted and causing the tray 29 to tip over. After a certain number of trays 29 are filled, they can be transported as a whole. In summary, when in use, the magnetic cores that have been powdered can be automatically arranged, and the entire row of magnetic cores can be sucked and stacked after the arrangement is completed.

[0025] In summary, when using the high-conductivity ferrite core stacking and powdering device, first, according to the model of the magnetic core, the receiving plate 16 and the receiving spring 15 of the corresponding specifications are placed in the temporary storage groove 14 to adapt to the arrangement of different magnetic cores. When the magnetic core moves on the slide rail 12, the blower 11 can transport cold air into the air supply pipe 9, and spray the cold air from the cold air outlet 10 to the magnetic core to cool the magnetic core to avoid the core temperature being too high and affecting the powdering and stacking. When the magnetic core passes through the powdering guide rail 202, the flap 203 can be pushed to rotate in the powdering guide rail 202, so that the flap 203 applies force to the top block 211, so that the top block 211 slides in the slide groove 207 through its own inclined surface, thereby driving the sealing plate 209 to move in the sealing groove 206 and open the The closing spring 208 is compressed to make the opening 210 coincide with the nozzle 205. At this time, the powder pre-loaded in the powder box 204 can be sprayed out of the powder box 204 through the nozzle 205 and sprinkled on the magnetic core. When the magnetic core lifts the flap 203, the flap 203 can synchronously push the plug plate 6 to slide in the through groove 5 and stretch the ventilation spring 8 to make the vent 7 coincide with the air inlet 3. At this time, the air flow in the air supply pipe 9 can enter the powder box 204 from the ventilation pipe 4 through the air inlet 3, increasing the air pressure in the powder box 204, thereby accelerating the speed at which the powder in the powder box 204 is sprayed out from the nozzle 205, thereby improving the powder spreading efficiency. After the magnetic core leaves from under the flap 203, the plug plate 6 can rebound under the action of the ventilation spring 8, pressurizing the flap 203 to make it rotate, and at the same time making the vent 7 coincide with the air inlet 3. The air inlet 3 is staggered to prevent the air flow from continuing to enter the powder box 204. After the flap 203 rotates under the action of external force and gravity, it no longer applies force to the top block 211, and the sealing plate 209 can rebound under the action of the opening and closing spring 208, so that the opening 210 and the nozzle 205 are staggered, so that the sealing plate 209 closes the nozzle 205 to prevent powder leakage. When the magnetic core moves to another powder-sprinkling guide rail 202 through the flipping guide rail 201, the spiral structure of the flipping guide rail 201 allows the magnetic core to flip 180° in the flipping guide rail 201, so that the other side of the magnetic core can be powdered when it moves on the other powder-sprinkling guide rail 202, ensuring that the powder can be fully adhered to the magnetic core, avoiding insufficient powder adhered to the surface of the magnetic core causing the magnetic core to stick to the tray 2 9, and when conveying magnetic cores of different specifications, the time and distance of the flap 203 turning upward can be automatically changed with the change of the magnetic core, thereby automatically controlling the opening and closing time and size of the nozzle 205, without manual adjustment, thereby improving the applicability and convenience of the device, and when the magnetic core moves in the powder-spreading guide rail 202, it will be decelerated in the powder-spreading guide rail 202 due to the pressure and friction of the flap 203, so as to avoid damage between the magnetic core and the device due to high-speed impact. After the powdering of the magnetic core is completed, the magnetic core leaves the powder-spreading guide rail 202 and slides into the bottom frame 13. After the magnetic core contacts the blocking plate 18, it will be intercepted by it and stay on the receiving plate 16. Under the gravity of the magnetic core, the receiving plate 16 is pressed down in the temporary storage groove 14 and compresses the receiving spring 15.The upper surface of the magnetic core is flush with the inner wall of the bottom frame 13 to avoid affecting the sliding of the subsequent magnetic core. When the receiving plate 16 moves downward, the card block 21 can be pressed to move downward synchronously in the card slot 20, so that the blocking plate 18 is pressed into the blocking slot 17 and the blocking spring 19 is compressed, and the blocking plate 18 is released from blocking the next magnetic core, so that the magnetic cores are arranged in order in the bottom frame 13. When the magnetic core reaches the end of the bottom frame 13 away from the powder sprinkling guide rail 202, it can simultaneously squeeze the spring hose 22 when pressing the receiving plate 16 below, and squeeze the air inside it through the connecting channel 23. The bottom frame 13 is inserted into the blocking groove 17 near one end of the powder-sprinkling guide rail 202, so that the air pressure raises the blocking plate 18 in the blocking groove 17 and stretches the blocking spring 19, so that the blocking plate 18 blocks the subsequent magnetic cores to avoid the existence of excess magnetic cores in the bottom frame 13 when the magnetic cores are transported. When the temporary storage grooves 14 in the bottom frame 13 are all filled with magnetic cores, the robot arm 25 can move the material-retrieving plate 26 into the bottom frame 13. When the spring switch 28 presses the blocking plate 18, the spring switch 28 can energize the electromagnet 27, so that the electromagnet 27 absorbs and removes the magnetic cores, and the bottom frame 13 The receiving plate 16 and the blocking plate 18 in the temporary storage tank 14 can rebound and reset under the action of the receiving spring 15 and the blocking spring 19, and the spring hose 22 can also be reset together with the receiving plate 16. In the process of the receiving plate 16 moving down and rebounding, the air in the temporary storage tank 14 can interact with the outside world through the constant pressure port 24 to ensure that the receiving plate 16 can move normally in the temporary storage tank 14. Then the robot arm 25 moves the material picking plate 26 to the tray 29, and puts the adsorbed magnetic core into the material placing tank 30. The magnetic core can squeeze the airbag 31, so that the airbag 31 covers and fixes the magnetic core. The spring switch 28 can prevent the magnetic core from escaping from the material trough 30 and protect it at the same time. When the spring switch 28 contacts the enclosure 33, the spring switch 28 can cut off the power of the electromagnet 27, release the adsorption of the magnetic core by the electromagnet 27, and leave the magnetic core in the material trough 30. When the tray 29 is full of magnetic cores, the empty tray 29 can be placed on the full tray 29. The trays 29 can be engaged with each other through the enclosure 33 and the enclosure trough 32 to prevent the tray 29 from being tilted and causing the tray 29 to tip over. After a certain number of trays 29 are filled, they can be transported as a whole.
