Description

Technical Field

[0001] The invention relates to the technical field of magnet processing, and in particular to a soft ferrite core processing device. Background Art

[0002] Soft ferrite core is a kind of high-frequency magnetic material, mainly used for high-frequency transformers, high-frequency magnetic rings, etc., to increase magnetic permeability and improve inductance quality factors. The processing of soft ferrite core is to first press the ferrite raw material, then sinter it at high temperature, and finally machine it into a finished core that meets application requirements. Therefore, the processing and molding of soft ferrite core requires sintering.

[0003] However, the existing sintering device for processing soft ferrite cores still has the following defects during use:

[0004] 1. In the process of conveying and sintering the soft ferrite cores, the existing sintering device does not flip the soft ferrite cores, and the bottom surface will always be attached to the conveyor belt. As a result, the soft ferrite cores are unevenly heated during the sintering process, which makes them prone to deformation and reduces the quality of the product.

[0005] 2. During the transportation and sintering of the soft ferrite cores, in order to facilitate the placement and collection of the soft ferrite cores, the soft ferrite cores are not stably limited, which makes the soft ferrite cores easy to roll, which is not conducive to the normal sintering.

[0006] 3. During the sintering process, both the iron oxidation and cooling of the soft ferrite core require sufficient contact with the air. However, the existing sintering device meets the requirements of sufficient iron oxidation and cooling by lengthening the conveyor line, which not only increases the cost but also reduces the processing efficiency. Summary of the invention

DETAILED DESCRIPTION

[0035] To make the purpose, technical solution and advantages of the embodiments of the present invention more clear, the technical solution in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0036] A soft ferrite core processing device according to a preferred embodiment of the present invention will be described in detail below. Figure 1-Figure 6 As shown, a soft ferrite core processing device comprises a support frame 1, a sintering furnace 2 is fixedly installed on the top of the support frame 1, the sintering furnace 2 is divided into three areas from left to right, namely a pre-sintering and shaping area, a high-temperature sintering area and a cooling area, a mounting clamp 3 is fixedly installed on one side adjacent to the top of the support frame 1, a connecting plate 4 is fixedly installed between the middle parts of the mounting clamp 3, a rotating roller 5 is connected between the left and right sides of the mounting clamp 3 for limited rotation, a conveyor belt 6 is wound around the outer sides of the rotating rollers 5 on the left and right sides, a placing and flipping assembly 7 is evenly arranged on the inner side of the conveyor belt 6, the conveyor belt 6 cooperates with the placing and flipping assembly 7 to place the soft ferrite core, and drives the soft ferrite core to pass through the sintering furnace 2, and can flip the soft ferrite core during the movement.

[0037] A motor 51 is fixedly mounted on the rear end of the right side of the rear mounting clamping plate 3 , and the motor 51 is transmission-connected to the right rotating roller 5 for driving the rotating roller 5 to rotate.

[0038] During sintering, the motor 51 is driven to rotate the roller 5 on the right side, thereby driving the conveyor belt 6 wound around the outside of the rollers 5 on both sides to rotate. During the rotation of the conveyor belt 6, the soft ferrite core to be sintered is placed from the left side of the sintering furnace 2 into the placement and flipping assembly 7 of the conveyor belt 6, and then conveyed to the right by the rotation of the conveyor belt 6, so that the soft ferrite core passes through the pre-sintering and shaping, high-temperature sintering and cooling of the sintering furnace 2 in sequence, and during the high-temperature sintering and cooling process, the soft ferrite core can be flipped and the air flow can be accelerated, and after sintering, the soft ferrite core will be dropped and collected on the right side of the conveyor belt 6.

[0039] Furthermore, if Figure 1 , Figure 7-Figure 10 , Fig.12 As shown, the placement and flipping assembly 7 includes a rotating drum 71, which is connected to the conveyor belt 6 by limiting rotation. The rotating drum 71 is a group of two and is evenly distributed inside the conveyor belt 6. The rotating drum 71 is hollow in design and has holes evenly opened on the periphery, which is conducive to the flow of air. The front and rear ends of the rotating drum 71 are fixedly installed with driving wheels 72, and the driving wheels 72 are located on the front and rear sides of the conveyor belt 6. The middle part of the rotating drum 71 and the driving wheel 72 is connected to the rotating shaft 73 by limiting rotation. The rotating shaft 73 penetrates the rotating drum 71 and the driving wheel 72 and extends to the outside of the driving wheels 72 on the front and rear sides. Gears 74 are fixedly installed on the front and rear ends of the rotating shaft 73, and fan blades 75 are fixedly installed on the periphery of the middle part of the rotating shaft 73. The fan blades 75 are located inside the rotating drum 71. When rotating, the air flow inside and outside the rotating drum 71 can be improved. A limiting assembly 76 is arranged between the two rotating drums 71 in a single group. The limiting assembly 76 is used to limit the placed soft magnetic ferrite core.

[0040] Friction strips 31 are fixedly installed on the top of the front and rear mounting plates 3, and racks 32 are fixedly installed on the outer sides of the friction strips 31 at the top of the front and rear mounting plates 3. The top of the rack 32 is designed to be bent, and the teeth of the rack 32 are designed to be downward at the bend. The starting points of the left sides of the friction strip 31 and the rack 32 are aligned with the starting points of the high-temperature sintering area of ​​the sintering furnace 2, and the ending points of the right sides of the friction strip 31 and the rack 32 are aligned with the ending points of the cooling area of ​​the sintering furnace 2. When the driving wheel 72 moves to the friction strip 31 with the conveyor belt 6, the bottom of the driving wheel 72 can be attached to the friction strip 31, so that the driving wheel 72 can rotate after contacting the friction strip 31, and at the same time, the top of the gear 74 can also mesh with the downward teeth of the rack 32, so that the gear 74 can rotate after meshing with the downward teeth of the rack 32, and the rotation direction is opposite to that of the driving wheel 72.

[0041] The principle of placing the flip assembly 7 to flip the soft ferrite core and accelerate the air flow during the high-temperature sintering and cooling process is as follows:

[0042] When the conveyor belt 6 drives the flip assembly 7 to transport the soft ferrite core placed above it from left to right, the starting point of the left side of the friction strip 31 and the rack 32 is aligned with the starting point of the high-temperature sintering area of ​​the sintering furnace 2. When the soft ferrite core is driven through the pre-sintering and molding area, the soft ferrite core will not be flipped, so the soft ferrite core will not be turned over during pre-sintering and molding, so as to avoid the loosening of the soft ferrite core and ensure that the soft ferrite core can be stably pre-sintered and hardened.

[0043] When the flip assembly 7 is placed to drive the soft ferrite core to move to the right to the high-temperature sintering area, the bottom of the driving wheel 72 is attached to the friction strip 31, so that the driving wheel 72 can rotate during the process of moving to the right, thereby driving the rotating drum 71 to rotate in the same direction. During the same-direction rotation of the rotating drum 71, the soft ferrite core above the two rotating drums 71 of the single group can be driven to rotate, thereby realizing the flipping of the soft ferrite core during high-temperature sintering and cooling, to ensure uniform heating of the soft ferrite core during sintering, to avoid deformation caused by uneven heating, and to improve product quality.

[0044] By utilizing the mutual meshing of the top of the gear 74 and the downward teeth of the rack 32, the gear 74 can also drive the rotating shaft 73 to rotate in the process of the rotating drum 71 driving the soft magnetic ferrite core to flip, and the rotation direction is opposite to the rotation direction of the rotating drum 71. Therefore, the rotating shaft 73 can drive the fan blades 75 to rotate more effectively inside the rotating drum 71. The design of the hollow and peripheral holes of the rotating drum 71 can accelerate the flow of air inside the rotating drum 71, thereby increasing the air flow inside and outside. Combined with the flipping of the soft magnetic ferrite core, it can be beneficial to the uniform iron oxidation during sintering of the soft magnetic ferrite core and the uniform heat dissipation during cooling, so as to meet sufficient iron oxidation and cooling, shorten the conveyor line, reduce costs, and improve processing efficiency.

[0045] Furthermore, if Figure 5-Figure 13 As shown, the limiting assembly 76 includes a fixed mounting block 761, a fixed mounting block 761 is fixedly mounted on the inner side of the conveyor belt 6 at a position aligned with the middle of the single group of rotating drums 71, a partition plate 762 is fixedly mounted on the outer side of the fixed mounting block 761, the partition plate 762 extends outward from the gap between the two rotating drums 71 of the single group, and the outer side of the partition plate 762 is circular and is located on the outer side between the two rotating drums 71 of the single group, and the front and rear sides of the fixed mounting block 761 on the inner side of the conveyor belt 6 are symmetrically limited and slidably connected with a movable mounting block 763, and the outer side of the movable mounting block 763 is fixedly mounted with a limiting plate 764 to limit the soft ferrite core placed above the single group of two rotating drums 71, and the fixed mounting The inner side of block 761 is limitedly and slidingly connected with a lifting rod 765, and a spring 766 is fixedly connected between one end of the lifting rod 765 located inside the fixed mounting block 761 and the inner wall of the fixed mounting block 761. A transmission rod 767 is transmission-connected between the front and rear ends of the inner side of the lifting rod 765 and the movable mounting blocks 763 on the front and rear sides. One end of the transmission rod 767 symmetrically distributed on the front and rear sides of the lifting rod 765 is hinged to the lifting rod 765, and the other side is extended outward and then hinged to the movable mounting blocks 763 on the front and rear sides of the fixed mounting block 761, so that in the process of the lifting rod 765 extending inward, the movable mounting blocks 763 on the front and rear sides can be pulled toward the middle by the transmission rod 767.

[0046] A pulley 768 is fixedly installed at one end of the inner side of the lifting rod 765, and a limiting slide bar 41 is fixedly installed in the center of the top of the connecting plate 4. The limiting slide bar 41 is distributed on the left and right, and a gap is opened in the middle. The limiting slide bar 41 extends symmetrically and tilted upward on the left and right sides. The pulley 768 is composed of a fixed rod fixedly installed on the inner side of the lifting rod 765 and rollers distributed front and back on the inner side. The diameter of the fixed rod is smaller than the width of the gap in the middle of the limiting slide bar 41, and the length of the rollers distributed front and back is greater than the width of the gap in the middle of the limiting slide bar 41, so that the pulley 768 can be adapted to the limiting slide bar 41. When the upper pulley 768 moves from left to right, the cooperation between the pulley 768 and the limiting slide bar 41 can first pull the lifting rod 765 located on the upper side downward on the left side, and then retract upward on the right side.

[0047] The principle of placing and collecting the soft ferrite cores and limiting the placed soft ferrite cores during sintering is as follows:

[0048] When placing, the soft ferrite core is placed from the left side above the two rotating drums 71 of the upper single group, and is located between the partition 762 and the limit plate 764. When following the conveyor belt 6 into the sintering furnace 2, the pulley 768 is coordinated with the limit slide 41, the limit slide 41 is used to limit the pulley 768, and the limit slide 41 is designed to extend symmetrically upward on the left and right sides. The pulley 768 can pull the lifting rod 765 downward. In the process of the lifting rod 765 moving downward, the transmission rod 767 can be used to pull the movable mounting blocks 763 on the front and rear sides of the fixed mounting block 761 to shrink toward the middle, thereby driving the limit plates 764 on both sides to shrink toward the middle, and cooperating with the partition 762 to limit the placed soft ferrite core to avoid excess rolling of the soft ferrite core, which is beneficial to the normal sintering.

[0049] After sintering is completed, the pulley 768 gradually disengages from the limiting slide bar 41, and the lifting rod 765 moves upward under the action of the restoring force of the spring 766, cooperating with the transmission rod 767 to make the movable mounting block 763 and the limiting plate 764 unfold again, so that the soft ferrite core can be normally detached and collected.

[0050] The above description of the disclosed embodiments enables one skilled in the art to implement or use the present invention. Various modifications to these embodiments will be apparent to one skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention will not be limited to the embodiments shown herein, but rather to the widest scope consistent with the principles and novel features disclosed herein.
