Description

Technical Field

[0001] The invention relates to the technical field of soft ferrite processing, in particular to an automatic arrangement device for soft ferrite magnetic core green sheets. Background Art

[0002] Soft ferrite, as the name suggests, is a magnetic material characterized by its "magnetic conductivity." Just as metals conduct electricity, some materials also conduct magnetism, which we call magnetic materials. Magnetic materials are categorized as hard and soft. Hard ferrites are permanent magnets, which exhibit magnetism without the need for an external solenoid to energize them, and their magnetism persists. Soft magnets, on the other hand, are inherently nonmagnetic; they only generate a magnetic field when an external solenoid is energized. This magnetic field disappears when the current is removed. Ferrites are "functional ceramic materials" made by sintering a mixture of iron oxide and other metal oxides. They possess excellent magnetic conductivity and, compared to standard metals, have lower coercivity and less residual magnetism after the external current is removed. During the arrangement process, the green magnetic cores need to be deburred, brushed with slurry, and sprinkled with powder to prevent product adhesion. However, manually stacking the green magnetic cores one by one results in low production efficiency. One molding machine requires one or more operators, which wastes manpower. If the operator uses improper force, the green magnetic cores can easily be damaged.

[0003] The utility model patent with authorization announcement number CN214610254U discloses an automatic blank arrangement device used in the automatic production process of soft magnetic ferrite, which includes a frame, which is the main frame; a central control box, a control panel, a placement table and a discharge table fixedly arranged on the frame; a conveyor belt arranged on the frame, and the conveyor belt is connected to a forming machine; a slurry brushing mechanism arranged on the conveyor belt; a push rod mechanism arranged at the rear end of the conveyor belt, which pushes rows of magnetic core blanks onto the placement table; an adsorption mechanism arranged directly above the placement table, which moves the arranged magnetic core blanks on the placement table to the discharge table for stacking; a powder sprinkling structure movably arranged on the frame, which can be moved directly above the discharge table for powder sprinkling; an alarm device arranged on the side of the frame. Since the magnetic core needs to be deburred on multiple sides, the device can only realize single-sided processing of the magnetic core, and further magnetic core reverse side process is required later, and the degree of operation automation is low. Summary of the Invention

[0004] The purpose of the present invention is to provide an automatic arrangement device for soft ferrite core green sheets, which has the effect of rapid automatic transportation.

[0005] The above technical objectives of the present invention are achieved through the following technical solutions: an automatic arrangement device for soft ferrite core green billets, comprising a forming machine, a frame, an upper conveyor belt and a lower conveyor belt arranged on the frame, and a transfer device arranged on the sides of the upper conveyor belt and the lower conveyor belt, the transfer device comprising a transfer frame, a transfer magnet arranged on the transfer frame, a lifting member for driving the transfer magnet to move up and down, and a flip member for controlling the rotation of the transfer magnet, an upper pushing cylinder is arranged on the frame, the piston end of the upper pushing cylinder is arranged on an upper pushing plate, the upper pushing cylinder drives the upper pushing plate to move toward one side of the transfer device, a lower pushing cylinder is arranged on the transfer frame, the piston end of the lower pushing cylinder is arranged on a lower pushing plate, and the lower pushing cylinder drives the lower pushing plate to move away from one side of the rotating device.

[0006] By adopting the above technical solution, the automatic arrangement process of the magnetic cores can be realized, wherein the magnetic cores prepared in the molding machine are transferred to the upper conveyor belt and arranged into strips. At this time, the transfer magnetic body in the transfer device is located on the same horizontal plane as the upper surface of the upper conveyor belt. Then the upper pushing cylinder pushes the upper pushing plate to push all the magnetic cores onto the transfer magnetic body, and then transfer them to the transfer rack below. Then the lower pushing cylinder pushes the lower pushing plate to push it to the lower conveyor belt for unified transfer. This method can not only realize the transfer of the magnetic cores, but also realize the reversal of the direction of the magnetic cores.

[0007] The present invention is further configured as follows: the flipping member includes a sliding block, a limiting frame, a rotating rod, and a toggle member; the sliding block is vertically slidably arranged on the lifting member; the lifting member drives the sliding block to move up and down; the rotating rod is rotatably arranged on the sliding block; the transfer magnet is arranged at the end of the rotating rod; the limiting frame is slidably arranged on the transfer frame; the toggle member is arranged on the rotating rod; the limiting frame controls the toggle member to drive the rotating rod to rotate.

[0008] The present invention is further configured as follows: the toggle member includes a control plate and a toggle rod, the control plate includes a fixed plate and three control arms, the three control arms are radially and evenly fixed on the fixed plate, the fixed plate is coaxially fixedly connected to the rotating rod, and the toggle rod is vertically axially fixedly connected to the end of the control arm away from the fixed plate.

[0009] The present invention is further configured as follows: the limiting frame includes a base frame, a bracket, and a limiting plate; a sliding groove is provided on the transfer frame; the base frame is slidably engaged in the sliding groove; the bracket is vertically arranged at both ends of the base frame; the limiting frame is relatively arranged at the upper end of the bracket; and a limiting triangle plate is vertically provided on the base frame.

[0010] By adopting the above technical solution, when the magnetic core is located on the upper surface of the transfer magnet, the lifting part will control the sliding block to move downward, and the sliding block will drive the transfer magnet to move downward through the rotating rod. When the toggle rod contacts the limit triangle plate on the limit frame, the toggle rod will push the limit frame to move horizontally along the sliding groove through the limit triangle plate. At this time, after the transfer magnet transports the magnetic core to the transfer frame, the lifting part drives the sliding block to move upward. When the toggle rod hits the limit plate on the limit frame, the toggle rod will drive the rotating rod to rotate, causing the rotating rod to rotate 180 degrees. At this time, the transfer magnet will also rotate 180 degrees with the rotating rod, allowing it to proceed to the next step of material connection.

[0011] The present invention is further configured as follows: a limiting member is provided on the sliding block, the limiting member includes a swing rod, a limiting support rod, and a limiting spring, the swing rod is radially fixed to the end of the rotating rod away from the toggle member, two limiting support rods are provided, and the two limiting support rods are provided on the sliding block obliquely below the rotating rod, a protrusion is provided below the sliding block, and the protrusion is connected to the end of the swing rod away from the rotating rod through a limiting spring.

[0012] By adopting the above technical solution, the setting of the limit member can ensure that when the toggle member drives the rotating rod to rotate, the rotation of the rotating rod is not excessive. When the toggle rod moves downward to push the limiting triangle plate, the thrust given to the toggle rod by the limiting triangle plate is offset by the limit member. At this time, the swing rod at the other end of the rotating rod is blocked by the limiting support rod below, so that the rotating rod cannot continue to rotate, which plays the role of limiting the rotating rod. Moreover, when the sliding block moves upward, the toggle rod contacts the limiting plate and the toggle rod is rotated. Due to the restriction of the swing rod by the limiting support rod, the rotating rod can only rotate 180 degrees. The tension of the limiting spring in the present invention can prevent the rotating rod from shaking.

[0013] The present invention is further configured as follows: the lifting component includes a lifting motor, a screw rod, and a guide rod; both ends of the screw rod are rotatably connected to the transfer frame; both ends of the guide rod are fixedly connected to the transfer frame; the guide rod is parallel to the screw rod; one side of the sliding block is threadedly connected to the screw rod; and the sliding block is slidably connected to the guide rod.

[0014] The present invention is further configured as follows: a magnetic conversion mechanism is provided in the transport magnetic body, the magnetic conversion mechanism includes a magnetic frame, a telescopic part and a conversion part arranged inside the magnetic frame, the conversion part includes an end rod, a conversion block, and a magnetic block, a rotating column is provided on the magnetic frame, the conversion block is rotatably connected to the rotating column, the magnetic block is movably arranged at the end of the conversion block, two end rods are provided on the side of the conversion block close to the telescopic part, the telescopic part drives the two end rods to drive the rotating block to rotate around the rotating column, and limited stop columns are provided on the magnetic frames on both sides of the rotating column, the upper and lower sides of the magnetic frame are set as magnetic conductive plates, and the other surfaces of the magnetic frame are insulating plates.

[0015] The present invention is further configured as follows: a card slot is provided at one end of the magnetic block, a card post is provided on the conversion block, the card post is movably connected to the card slot, the magnetic block is located at one end of the card slot and is movably sleeved with a retaining ring on the outside, a baffle is provided in the middle of the magnetic block, a compression spring is movably sleeved on the magnetic block between the retaining ring and the baffle, and limited output plates are provided on the upper and lower surfaces of the magnetic suction frame.

[0016] The present invention is further configured as follows: the telescopic part includes a telescopic head, a connecting rod, a telescopic rod, a push rod, and a telescopic spring; the telescopic head is rotatably connected to the magnetic frame; the telescopic rod and the telescopic head are connected by a connecting rod; the push rod is radially fixedly arranged on the end of the telescopic rod away from the connecting rod; a telescopic spring is movably sleeved on the connecting rod between the telescopic head and the telescopic rod; a vertical groove is provided on the outer surface of the telescopic rod relative to the axial direction; an inclined groove is connected end to end between the two vertical grooves; a guide column is provided inside the magnetic frame; the guide column is connected to the magnetic frame by a fixed spring; the guide column is movably clamped between the vertical groove or the inclined groove.

[0017] The present invention is further configured as follows: two inclined slopes are provided on the upper and lower sides of the end of the telescopic head, and two protruding columns are provided on the transfer rack, and the two protruding columns are provided with inclined surfaces. When the telescopic head moves downward, the inclined surfaces on the protruding columns contact the inclined slopes and push the telescopic head to move toward the inside of the magnetic rack.

[0018] By adopting the above technical solution, the magnetic conversion mechanism of the present invention can realize the magnetic conversion process on the upper and lower sides of the magnetic frame. When the magnetic frame with the magnetic core moves to the transfer frame, the magnetic block in the magnetic conversion mechanism is in contact with the bottom of the magnetic frame. The magnetic core is located at the bottom of the magnetic frame due to the action of magnetic attraction. When the telescopic head contacts the protruding column on the transfer frame, the protruding column will squeeze the telescopic head, causing the telescopic head to move toward the inside of the magnetic frame. The telescopic head will drive the push rod on the telescopic rod to move through the connecting rod, and the push rod will push the end rod on the conversion block to rotate the conversion block. During the rotation of the conversion block, the other end of the conversion block will drive the magnetic block to rotate to the upper end of the magnetic frame. At this time, the lower side of the magnetic frame loses its magnetism. When the magnetic frame moves upward again, the magnetic core is located on the transfer frame, and the upper and lower sides of the magnetic core are reversed.

[0019] The beneficial effects of the present invention are:

[0020] 1. The present invention can realize the automatic arrangement process of magnetic cores, wherein the magnetic cores prepared in the forming machine are transferred to the upper conveyor belt and arranged into strips. At this time, the transfer magnetic body in the transfer device is located on the same horizontal plane as the upper surface of the upper conveyor belt. Then the upper push cylinder pushes the upper push plate to push all the magnetic cores onto the transfer magnetic body, and then transfer them to the transfer rack below. Then the lower push cylinder pushes the lower push plate to push them to the lower conveyor belt for unified transfer. This method can not only realize the transfer of magnetic cores, but also realize the reversal of the direction of the magnetic cores.

[0021] 2. When the magnetic core is located on the upper surface of the transfer magnet, the lifting part will control the sliding block to move downward, and the sliding block will drive the transfer magnet to move downward through the rotating rod. When the toggle rod contacts the limit triangle on the limit frame, the toggle rod will push the limit frame to move horizontally along the sliding groove through the limit triangle. At this time, after the transfer magnet transports the magnetic core to the transfer frame, the lifting part drives the sliding block to move upward. When the toggle rod hits the limit plate on the limit frame, the toggle rod will drive the rotating rod to rotate, causing the rotating rod to rotate 180 degrees. At this time, the transfer magnet will also rotate 180 degrees with the rotating rod, allowing it to proceed to the next step of material connection.

[0022] 3. The setting of the limit member can ensure that when the toggle member drives the rotating rod to rotate, the rotating rod does not rotate excessively. When the toggle rod moves downward to push the limiting triangle plate, the thrust given to the toggle rod by the limiting triangle plate is offset by the limit member. At this time, the swing rod at the other end of the rotating rod is blocked by the limiting support rod below, so that the rotating rod cannot continue to rotate, which plays the role of limiting the rotating rod. Moreover, when the sliding block moves upward, the toggle rod contacts the limiting plate and the toggle rod is rotated. However, due to the restriction of the swing rod by the limiting support rod, the rotating rod can only rotate 180 degrees. The tension of the limiting spring in the present invention can prevent the rotating rod from shaking.

[0023] 4. The magnetic conversion mechanism in the present invention can realize the magnetic conversion process on the upper and lower sides of the magnetic frame. When the magnetic frame with the magnetic core moves to the transfer frame, the magnetic block in the magnetic conversion mechanism is in contact with the bottom of the magnetic frame. The magnetic core is located at the bottom of the magnetic frame due to the action of magnetic attraction. When the telescopic head contacts the protruding column on the transfer frame, the protruding column will squeeze the telescopic head, causing the telescopic head to move toward the inside of the magnetic frame. The telescopic head will drive the push rod on the telescopic rod to move through the connecting rod, and the push rod will push the end rod on the conversion block to rotate the conversion block. During the rotation of the conversion block, the other end of the conversion block will drive the magnetic block to rotate to the upper end of the magnetic frame. At this time, the lower side of the magnetic frame loses its magnetism. When the magnetic frame moves upward again, the magnetic core is located on the transfer frame, and the upper and lower sides of the magnetic core are reversed. BRIEF DESCRIPTION OF THE DRAWINGS

[0037] By adopting the above technical solution, the automatic arrangement process of the magnetic cores can be realized, wherein the magnetic cores prepared in the molding machine 1 are transferred to the upper conveyor belt 21 and arranged into strips. At this time, the transfer magnetic body 32 in the transfer device 3 is located on the same horizontal plane as the upper surface of the upper conveyor belt 21, and then the upper pushing cylinder 23 pushes the upper pushing plate 24 to push all the magnetic cores onto the transfer magnetic body 32, and then transfer them to the transfer rack 31 below, and then the lower pushing cylinder 25 pushes the lower pushing plate 26 to push it to the lower conveyor belt 22 for unified transfer.
