Description

Technical Field

[0001] The present invention relates to the technical field of capacitor preparation, and in particular to tantalum capacitor production equipment. Background Art

[0002] Tantalum capacitors are small in size but have a large capacitance. They have excellent performance and are widely used in industrial control, film and television equipment, communication instruments and other products. During the production process of tantalum capacitors, tantalum powder needs to be mixed with a binder. After the solvent evaporates, it is pressed together with tantalum wire into a tantalum anode block. After the anode tantalum block is pressed and formed, it is also necessary to dewax and sinter to remove the binder in the pressed tantalum block and burn the tantalum block to have a certain mechanical strength.

[0003] However, the existing tantalum capacitor production equipment still has the following defects during the dewaxing and sintering process of tantalum blocks:

[0004] 1. The dewaxing and sintering of tantalum blocks have strict control requirements on the starting temperature, heating, insulation, cooling and other parameters. The existing equipment needs to be separated in different heating equipment when dewaxing and sintering tantalum blocks, which is cumbersome to operate and requires the tantalum blocks to be re-moved, which reduces the efficiency of dewaxing and sintering of tantalum blocks;

[0005] 2. The existing tantalum capacitor production equipment cannot turn over or rotate the tantalum blocks during dewaxing and sintering, so that the various sides of the tantalum blocks cannot be heated evenly. Therefore, when the tantalum blocks are dewaxed to volatilize the binder, and when the tantalum blocks are sintered to become microporous bodies with certain mechanical strength, volatilization is easily blocked and the resulting microporous bodies are unevenly distributed, thereby reducing the production quality of tantalum capacitors. Summary of the invention

[0006] The purpose of the present invention is to solve the problem that the dewaxing and sintering of the tantalum block cannot be carried out simultaneously, which reduces the efficiency of the dewaxing and sintering of the tantalum block, and the tantalum block cannot be turned over and rotated during the dewaxing and sintering of the tantalum block, so that the binder cannot evaporate, the formed microscopic porous body is unevenly distributed, and the production quality of the tantalum capacitor is reduced. The present invention provides a tantalum capacitor production equipment.

[0007] In order to achieve the above-mentioned purpose, the present invention specifically adopts the following technical solutions:

[0008] A tantalum capacitor production equipment includes a sintering furnace and a cover plate. There are two cover plates, which are symmetrically distributed on both sides of the sintering furnace. The inside of the sintering furnace is divided into two different temperature zones on both sides, which are used for dewaxing and sintering respectively. Limiting columns are evenly fixedly installed at adjacent ends of the cover plates. The limiting columns are slidingly connected to the inside of the two sides of the sintering furnace. A lock is clamped between the cover plates and the two sides of the sintering furnace. A sleeve is fixedly installed in the center of the adjacent end of the cover plate, and a sliding column is sleeved between the sleeves on both sides. Driving components are arranged inside the cover plates on both sides, and a placement component is arranged on the outside of the sliding column.

[0009] Furthermore, the driving assembly includes a rotating drum, the interiors of the cover plates on both sides are limitedly and slidably connected to the rotating drum, the adjacent ends of the rotating drum on both sides extend inwardly to the inner side of the cover plate, the rotating drum is located at one end inside the cover plate and is fixedly installed with a gear ring, the upper part of the gear ring inside the cover plate is limitedly and rotatably connected to a threaded rod, one end of the threaded rod is transmission connected to motor 1 for driving the threaded rod to rotate, the interior of an adjacent side of the rotating drum is symmetrically and rotationally connected to a rotating shaft, the periphery of the rotating shaft is symmetrically and fixedly installed with a winding drum, one end of the rotating shaft is fixedly installed with a driven wheel, the interior of an adjacent side of the rotating drum close to the driven wheel is fixedly installed with a motor 2, a driving wheel is limitedly and rotatably connected between the driven wheels on the periphery of the adjacent side of the rotating drum, and the driving wheel is transmission connected to motor 2 for driving the driving wheel to rotate, and a belt is transmission connected between the driven wheels and the driving wheels on both sides.

[0010] Furthermore, the threaded rod is located on the upper side of the gear ring and meshes with the gear ring, so that the threaded rod can drive the gear ring to rotate during the rotation process.

[0011] Furthermore, the number of rotating shafts inside a single rotating drum is two, the number of winding drums outside a single rotating shaft is two, and the four rotating shafts are symmetrically distributed inside the rotating drum.

[0012] Furthermore, the diameter of the driving wheel is larger than the diameter of the driven wheels on both sides, the belt passes between the driven wheels on both sides, and the inner side of the middle part of the belt is squeezed and contacted with the two sides of the driving wheel with a larger diameter. Therefore, when the motor 2 drives the driving wheel to rotate, the driven wheels on both sides can be driven to rotate simultaneously through the action of the belt.

[0013] The cam is fixedly connected to the outer side of the sliding column, and the outer side of the cam is rotatably connected to the rotating disk so that the rotating disk can rotate outside the cam. The outer side of the rotating disk is rotatably connected to a rocker arm, and two of the rocker arms are in a group and are evenly distributed on the periphery of the rotating disk. A placement seat is inserted into the inner part of the rocker arm away from the rotating disk, and a tantalum block is clamped on the inner limit of the placement seat. Adjacent sides of the two rocker arms in a single group are both limited and rotatably connected to a transmission rod, and a telescopic rod is slidably connected to the center between the two rocker arms in a single group on the periphery of the rotating disk. A round head is fixedly installed at one end of the telescopic rod inside the rotating disk, which should be better in contact with the cam to produce telescopic movement. A spring one is fixedly connected between the round head and the inner wall of the rotating disk, and the spring one is wrapped around the outer side of the telescopic rod. The telescopic rod is sleeved on one side of the rotating disk, and a spring two is fixedly connected between one end of the telescopic rod located inside the sleeve and the inner wall of the sleeve, so that the sleeve can elastically telescope.

[0014] Furthermore, the periphery of the cam is provided with arc-shaped protrusions extending evenly outwards, which can lift up the telescopic rods in turn.

[0015] Furthermore, one side of the transmission rod is hinged to the adjacent side of the swing arm, and the other side is hinged to the sleeve after extending outward, so that when the sleeve follows the telescopic rod to telescope and swing, the swing arm can be driven to cross-swing through the transmission rod.

[0016] Furthermore, a pulling rope is fixedly connected between the winding drum and both ends of the turntable on both sides, so that the turntable can be driven to move by winding the pulling rope by the winding drum. At the same time, when the winding drum rotates with the turntable, the turntable can also be driven to rotate by the pulling rope.

[0017] The beneficial effects of the present invention are as follows:

[0018] 1. The present invention, through the coordinated design of the driving component and the placing component, can drive the tantalum block to rotate while sliding inside the sintering furnace to complete dewaxing and sintering, and can also drive the tantalum block to repeatedly swing and turn over, thereby ensuring that the tantalum block is heated evenly on all sides inside the sintering furnace, improving the dewaxing and sintering effects of the tantalum block, and ensuring the production quality of tantalum capacitors.

[0019] 2. The present invention, through the design of different temperature zones on both sides of the sintering furnace, utilizes the cooperation of the driving assembly and the pulling rope, so that the turntable can drive the tantalum block to rotate from the low-temperature side to the high-temperature side inside the sintering furnace, and then cooperates with the rotation and swinging of the tantalum block to complete the dewaxing and sintering of the tantalum block in the sintering furnace. The operation is more convenient and there is no need to re-carry, thereby improving the efficiency of dewaxing and sintering of the tantalum block. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0032] 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.

[0033] A tantalum capacitor production device according to a preferred embodiment of the present invention will be described in detail below. Figure 1-11 As shown, a tantalum capacitor production equipment includes a sintering furnace 1 and a cover plate 2. There are two cover plates 2, which are symmetrically distributed on both sides of the sintering furnace 1, and the inside of the sintering furnace 1 is divided into two different temperature zones on both sides, which are used for dewaxing and sintering respectively. Limiting columns 3 are evenly fixedly installed at adjacent ends of the cover plates 2. The limiting columns 3 are slidingly connected to the inside of both sides of the sintering furnace 1. A lock 4 is clamped between the cover plate 2 and the two sides of the sintering furnace 1. A sleeve 5 is fixedly installed in the center of the adjacent end of the cover plate 2, and a sliding column 6 is sleeved between the sleeves 5 on both sides. A driving assembly 7 is arranged inside the cover plates 2 on both sides, and a placement assembly 8 is arranged on the outside of the sliding column 6.

[0034] The driving assembly 7 includes a rotating drum 71, and the inside of the two side cover plates 2 are both limitedly slidably connected with the rotating drum 71, and the adjacent ends of the rotating drum 71 on both sides extend inwardly to the inner side of the cover plate 2, and the rotating drum 71 is located at one end inside the cover plate 2 and is fixedly installed with a gear ring 72, and a threaded rod 73 is limitedly rotatably connected above the gear ring 72 inside the cover plate 2, and one end of the threaded rod 73 is transmission-connected to a motor 74 for driving the threaded rod 73 to rotate, and the threaded rod 73 is located on the upper side of the gear ring 72 and meshes with the gear ring 72, so that the threaded rod 73 can drive the gear ring 72 to rotate during the rotation process.

[0035] The inner side of the adjacent rotating drum 71 is symmetrically limited and rotatably connected with a rotating shaft 75, and the outer side of the rotating shaft 75 is symmetrically fixed with a winding drum 76. The number of rotating shafts 75 inside a single rotating drum 71 is two, and the number of winding drums 76 outside a single rotating shaft 75 is two, and the four rotating shafts 75 are symmetrically distributed inside the rotating drum 71. A driven wheel 77 is fixedly installed at one end of the rotating shaft 75. A motor 2 78 is fixedly installed at one end of the inner side of the adjacent rotating drum 71 close to the driven wheel 77. A driving wheel 76 is fixedly installed between the driven wheels 77 on the outer side of the adjacent rotating drum 71. The driven wheel 79 is connected to the motor 2 78 for driving the driving wheel 79 to rotate. The driven wheels 77 on both sides are connected to the driving wheel 79 by a belt 710. The diameter of the driving wheel 79 is larger than the diameter of the driven wheels 77 on both sides. The belt 710 passes between the driven wheels 77 on both sides, and the inner side of the middle part of the belt 710 is squeezed and contacted with the two sides of the driving wheel 79 with a larger diameter. Therefore, in the process of the motor 2 78 driving the driving wheel 79 to rotate, the driven wheels 77 on both sides can be driven to rotate at the same time through the action of the belt 710.

[0036] The placement assembly 8 includes a cam 81, the outer side of the slide column 6 is limitedly slidably connected to the cam 81, the periphery of the cam 81 is provided with an arc-shaped protrusion extending evenly outward, which can lift the telescopic rod 85 in turn, the outer side of the cam 81 is limitedly rotatably connected to the turntable 82, so that the turntable 82 can rotate on the outer side of the cam 81, and the outer side of the turntable 82 is limitedly rotatably connected to the swing rod 83, two swing rods 83 are in a group, and are evenly distributed on the periphery of the turntable 82, and the inner side of the swing rod 83 away from the turntable 82 is plugged with a placement seat 9, and the inner limit clamping of the placement seat 9 There is a tantalum block 10, and the adjacent sides of the two rocker rods 83 of a single group are limitedly rotated and connected with a transmission rod 84. A telescopic rod 85 is slidably connected to the center between the two rocker rods 83 of the single group on the periphery of the turntable 82. The telescopic rod 85 is located inside the turntable 82 and a round head 86 is fixedly installed at one end. It should be better in contact with the cam 81 to produce expansion and contraction. A spring 87 is fixedly connected between the round head 86 and the inner wall of the turntable 82. The spring 87 is wrapped around the outside of the telescopic rod 85. The periphery of the cam 81 is provided with an arc-shaped protrusion extending evenly outward, which can lift the telescopic rod 85 in turn.

[0037] The telescopic rod 85 is located on one side outside the turntable 82 and is sleeved with a socket 88. A spring 89 is fixedly connected between one end of the telescopic rod 85 located inside the socket 88 and the inner wall of the socket 88, so that the socket 88 can be elastically extended and retracted. One side of the transmission rod 84 is hinged to the adjacent side of the rocker arm 83, and the other side is hinged to the socket 88 after extending outward. Therefore, in the process of the socket 88 following the telescopic rod 85 to extend and retract and swing, the rocker arm 83 can be driven to cross-swing through the transmission rod 84.

[0038] A pulling rope 11 is fixedly connected between the two sides of the winding drum 76 and the two ends of the turntable 82. Therefore, by winding the pulling rope 11 by the winding drum 76, the turntable 82 can be driven to move. At the same time, when the winding drum 76 rotates following the turntable 71, the turntable 82 can also be driven to rotate by the pulling rope 11.

[0039] The working principle of the present invention is:

[0040] In the production process of tantalum capacitors, when the tantalum block 10 needs to be dewaxed and sintered, the pressed tantalum block 10 is fixed on the placement seat 9 by inserting the tantalum wire to complete the fixation of the tantalum block 10 and the placement seat 9, and then the cover plate 2 on the lower temperature side of the sintering furnace 1 is opened, and the placement seat 9 with the tantalum block 10 is fixed on the rocker rod 83, thereby completing the placement of the tantalum block 10 in the sintering furnace 1.

[0041] After placement is completed, the opened cover plate 2 is slid closed by the limiting column 3 and locked by the lock buckle 4. When the sintering furnace 1 is started for heating, the motor 2 78 on one side is started to drive the driving wheel 79 to rotate. During the rotation of the driving wheel 79, the transmission effect of the belt 710 can drive the driven wheels 77 on both sides to rotate simultaneously, and then drive the rotating shaft 75 and the winding drum 76 to rotate simultaneously, so that the winding drum 76 winds up the pulling rope 11, and then the pulling rope 11 pulls the turntable 82 and the cam 81 to slide on the outside of the sliding column 6, so that the turntable 82 drives the placed tantalum block 10 to rotate from the low-temperature side to the high-temperature side inside the sintering furnace 1, so that the tantalum block 10 is first dewaxed on the low-temperature side and then sintered on the high-temperature side.

[0042] The cam 81 is engaged with the toothed ring 72 by the threaded rod 73, and the toothed ring 72 and the rotating drum 71 on both sides are engaged with each other to drive the rotating disk 82 and the cam 81 to rotate synchronously in the same direction. The telescopic rod 85 is repeatedly extended and retracted during the movement. When the telescopic rod 85 is extended outward, the two rocker arms 83 in each group can be swung outward through the action of the transmission rod 84. When the rocker arms 83 are swung to the aligned state, the inertia of the rocker arms 83 during the swinging and the design of the spring 89 between the sleeve 88 and the telescopic rod 85 can make the sleeve 88 elastically retract inward. Therefore, with the inertia of the rocker arms 83 during the swinging, the rocker arms 83 can be cross-displaced after alignment. At this time, with the inward retraction of the telescopic rod 85, the swing of the rocker arms 83 can be realized. Then, in the process of repeated telescopic movement of the telescopic rod 85, the rocker arms 83 can be reciprocated and cross-swung, thereby realizing the turning over of the tantalum block 10 on the rocker arms 83. With the rotation of the tantalum block 10, the uniform heating of each surface of the tantalum block 10 inside the sintering furnace 1 is further improved, and the dewaxing and sintering effects of the tantalum block 10 are improved.

[0043] After the dewaxing and sintering of the tantalum block 10 are completed, the cover plate 2 on the other side is opened and the tantalum block 10 is removed, and then the motor 2 78 on the other side is started to move the turntable 82 back to the side with a lower temperature in the sintering furnace 1 to facilitate the next round of dewaxing and sintering of the tantalum block 10.

[0044] 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.
