Description

Technical Field

[0001] This utility model belongs to the field of anode foil sintering equipment, specifically relating to a sintering device for sintered anode foil for aluminum electrolytic capacitors. Background Technology

[0002] In the production process of aluminum electrolytic capacitor anode foil, a high-temperature sintering process needs to be completed in a vacuum environment. Existing sintering equipment generally uses a fixed winding fixture to place the anode foil. The anode foil to be sintered is wound into a roll on the surface of the fixture and then sent into the vacuum sintering furnace for heating.

[0003] Traditional tooling relies solely on simple partitions to separate multiple layers of anode foil. The spacing between the partitions is fixed and the number of partition points is limited. During the sintering process, the thin anode foil is easily deformed due to high-temperature thermal expansion and its own tension, resulting in large-area contact between the surfaces of adjacent foil layers. Under high-temperature vacuum sintering conditions, the oxide layer and etched microstructures on the surface of the foil are easily fused and adhered to each other. When the foil is unwound after sintering, holes, powdering, tearing, and scrapping will appear on the surface of the foil, significantly reducing the yield of finished products.

Under vacuum and high-temperature conditions, each layer of anode foil can be in full contact with the high-temperature atmosphere, preventing foil surface welding and adhesion. This fundamentally solves the defects of foil tearing and powder shedding after sintering, significantly improving the yield of finished anode foil products. Attached Figure Description

Detailed Implementation

[0016] The sintering apparatus for sintered anode foil for aluminum electrolytic capacitors according to the present invention will be described in more detail below with reference to the accompanying drawings and specific embodiments.

[0017] In the description of this utility model, it should be understood that the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0018] This embodiment discloses a sintering apparatus for sintered anode foil used in aluminum electrolytic capacitors, such as... Figures 1-8 As shown, it includes a vacuum sintering furnace 1 and a winding device. A furnace cover 2 is hinged to the opening of the vacuum sintering furnace 1. The winding device is set corresponding to the entrance of the vacuum sintering furnace 1. A removable winding isolation device is installed inside the vacuum sintering furnace 1. Vacuum sintering furnace 1 provides a sealed high-temperature reaction chamber for the high-temperature vacuum sintering of anode foil. Furnace cover 2 enables the furnace body to open and close in a sealed manner, ensuring a stable internal vacuum environment during the sintering process. The entire winding isolation device can be pulled out from inside the vacuum sintering furnace 1, allowing operators to complete anode foil loading, rewinding, cleaning, and maintenance operations outside the furnace without entering the high-temperature furnace chamber. This significantly reduces the difficulty of loading and unloading operations, avoids burns to personnel from the high-temperature furnace body, and shortens the waiting time for the furnace body to cool down and heat up, thereby improving the overall continuity of sintering production.

[0019] The winding isolation device includes two winding reels with adjustable spacing, and multiple sets of chain isolation components are arranged in a ring on the winding reels; Two sets of winding reels are arranged opposite each other, and the spacing between them can be adjusted according to the width and specifications of the anode foil to meet the sintering requirements of various anode foil models. Multiple sets of chain isolation components are evenly arranged in a ring around the circumference of the winding reels. The anode foil is wound in layers between each set of chain isolation components. Adjacent foils are completely separated by the chain isolation components, preventing the foils from sticking together during the sintering process. This ensures uniform heating of the anode foil surface and eliminates the problems of insufficient sintering, adhesion, and scrap after sintering.

[0020] The chain isolation assembly includes two corresponding sprockets 17 and a chain 18 with multiple chain links hinged end to end. The surfaces of the chain links of the chain 18 are fixed with roller-type clamping structures at intervals.

[0021] The sprockets 17 work in pairs to drive the chain 18 to rotate in a cycle. The chain 18 is composed of several independent chain links that are hinged together in sequence. It can rotate smoothly in a circular motion with the sprockets 17, driving the anode foil to move at a uniform speed. The roller clamping structure includes a base plate 19 fixed at intervals on the surface of the chain links. Two corresponding isolation cylinders 20 are rotatably connected to the surface of the base plate 19. The two isolation cylinders 20 are used to clamp the anode foil. An empty chain link is reserved between two adjacent chain links equipped with the roller clamping structure. The two corresponding isolation cylinders 20 can stably clamp the edge of the anode foil. The interval arrangement reduces the contact area between the clamping components and the anode foil, avoids the clamping point from being blocked and causing poor local sintering, and can evenly distribute the clamping force to prevent the thin anode foil from being clamped and stretched and deformed. The roller structure can adapt to the slight deviation of the foil, reducing the risk of foil wrinkles and foil breakage. The roller clamping components are installed at intervals on the surface of the chain links and can rotate synchronously with the chain 18. The clamping point moves synchronously with the anode foil, stably supporting the edge of the foil throughout the process, and there will be no scratches on the foil surface caused by relative sliding friction between the clamping components and the foil.

[0022] The surface of the right winding reel is rotatably connected to a support screw 11. The surface of the left winding reel is provided with a mounting hole and an adjusting nut 21 is provided on both sides. The support screw 11 is placed inside the mounting hole, and the adjusting nut 21 is threadedly connected to the support screw 11. A spacing adjustment assembly is installed on the lower side of the two winding reels.

[0023] The support screw 11 passes between the two winding reels, serving as a coaxial support reference for the two sets of winding reels. By rotating the adjusting nuts 21 at both ends of the support screw 11, the left winding reel can be moved horizontally left and right along the support screw 11, achieving coarse adjustment of the distance between the two sets of winding reels. The matching spacing adjustment component below provides synchronous support and fine spacing adjustment functions. The upper and lower dual spacing adjustment structures work together to ensure that the winding reels are evenly stressed after adjustment, preventing unilateral tilting and ensuring that the two winding reels always remain parallel, avoiding unilateral deviation during anode foil feeding.

[0024] The winding reel includes two corresponding mounting plates 9 and a protective frame 10 fixed to the outer end of the mounting plates 9. The chain isolation assembly is mounted on the surface of the mounting plates 9. The mounting plates 9 corresponding to the chain isolation assembly are respectively provided with strip-shaped openings 22 for protruding the chain isolation assembly. The mounting hole is opened in the middle of the left mounting plate 9 and the protective frame 10, and the right mounting plate 9 and the protective frame 10 are rotatably connected to the support screw 11.

[0025] The mounting plates 9 on both sides provide stable mounting bases for the sprockets 17 and chains 18. The protective frame 10 wraps around the outside of the mounting plates 9 to form an outer protective structure, preventing foil fragments and furnace impurities from directly impacting the chain isolation components during sintering, thus reducing wear and jamming of the sprockets 17 and chains 18. The mounting plates 9 and the protective frame 10 have a through-hole for mounting, and the support screw 11 passes through the hole to achieve the series assembly of the left and right winding discs. The right winding disc rotates with the support screw 11, allowing the winding disc to rotate freely during the adjustment process without being jammed by the torque generated by the screw rotation.

[0026] The spacing adjustment assembly includes a horizontally arranged horizontal plate 7 and vertical plates 8 arranged on both sides of the upper end of the horizontal plate 7. The left vertical plate 8 is rotatably connected to the upper protective frame 10. The upper end of the right vertical plate 8 is rotatably connected to a horizontally arranged spline shaft 14. The right end of the support screw 11 is fixedly connected to a connecting cylinder 12. The right end of the connecting cylinder 12 is provided with a spline groove 13. The spline shaft 14 is inserted into the spline groove 13. The horizontal plate 7 serves as the base supporting the entire spacing adjustment assembly, while the two vertical plates 8 on either side support the left and right sets of winding discs respectively. The splined shaft 14 and the splined groove 13 inside the connecting cylinder 12 interlock to form a torque transmission structure. When the drive component rotates the splined shaft 14, it synchronously drives the support screw 11 to rotate, achieving synchronous spacing adjustment of the left and right winding discs. The splined interlocking structure allows axial relative sliding between the splined shaft 14 and the connecting cylinder 12, preventing transmission jamming during winding disc spacing adjustment, maintaining synchronous power transmission, and facilitating disassembly. The left vertical plate 8 is rotatably assembled with the protective frame 10, adapting to angular changes caused by the horizontal movement of the winding discs, ensuring a flexible and interference-free support structure.

[0027] The vertical plate 8 on the left side is horizontally slidably connected to the horizontal plate 7 along the length direction, the vertical plate 8 on the right side is fixedly connected to the horizontal plate 7, and an adjusting screw 15 is threadedly connected to the surface of the vertical plate 8 on the left side. The adjusting screw 15 is rotatably connected to the horizontal plate 7, and an adjusting knob 16 is fixedly connected to the left end of the adjusting screw 15.

[0028] The right vertical plate 8 is rigidly fixed to the horizontal plate 7, serving as the overall fixing reference. The left vertical plate 8 can slide horizontally along the length of the horizontal plate 7. Rotating the adjustment knob 16 will drive the adjustment screw 15 to rotate, and the left vertical plate 8 will be moved left and right by the threaded transmission, thereby completing the fine adjustment of the spacing between the two sets of winding discs. The threaded transmission has a self-locking characteristic. After the adjustment is completed, releasing the adjustment knob 16 will automatically lock the left vertical plate 8 in the current position without the need for additional locking parts. Even under long-term high-temperature sintering conditions, there will be no spacing deviation, ensuring the stability of the foil winding width.

[0029] The vacuum sintering furnace 1 has guide rails 5 fixedly connected horizontally along the axial direction on both sides of its interior. The bottom sides of the horizontal plate 7 are respectively fixedly connected to guide sliders 6, and the guide sliders 6 are slidably connected to the guide rails 5.

[0030] Guide rail 5 is laid along the axial direction of vacuum sintering furnace 1, and guide slider 6 is rigidly connected to the bottom of horizontal plate 7. The two form a sliding guide pair. The entire winding isolation device is smoothly pulled in and out of the furnace body by slider 6 along guide rail 5. The cooperation of guide rail 5 and slider 6 restricts the device to only move in a straight line. There will be no left or right or up and down deviation during the extraction and pushing process, avoiding the winding isolation device from scratching the inner wall of the furnace body. At the same time, the sliding support shares the overall weight of the winding isolation device, and a single person can easily complete the removal operation of the device, reducing the load of pushing and pulling the device.

[0031] The winding device includes a mounting frame 4, with a swing frame 35 hinged to the left end of the mounting frame 4. Right-angle plates 32 are fixedly connected to the front and rear sides of the right end of the swing frame 35, and a roll 3 is detachably installed between the two right-angle plates 32. Electric telescopic rods 34 are respectively provided on the upper sides of the swing frame 35. The fixed end of the electric telescopic rod 34 is hinged to the mounting frame 4, and the telescopic end of the electric telescopic rod 34 is hinged to the swing frame 35.

[0032] Mounting frame 4 provides a fixed support base for the entire winding equipment. The left end of the swing frame 35 is hinged to mounting frame 4 to form a swing structure. The swing frame 35 can be driven to rotate up and down by the synchronous extension and retraction of the double-sided electric telescopic rods 34. The drum 3 is mounted between two right-angle plates 32. When the swing frame 35 rotates downward, the drum 3 moves down, allowing operators to easily disassemble and replace the drum 3. After rotating upward and resetting, the drum 3 is raised to the corresponding height and precisely aligns with the discharge position of the vacuum sintering furnace 1, realizing automatic winding of the anode foil after sintering. The synchronous drive of the double-sided electric telescopic rods 34 ensures that the force on the swing frame 35 is even when it rotates, preventing the drum 3 from getting stuck due to unilateral tilting.

[0033] The inner sides of the drum 3 are equipped with support cylinders 31 that are interlocked with each other. The upper end of the right-angle plate 32 is provided with a groove facing downwards. The outer end of the support cylinder 31 is stuck in the groove. A limit ring 33 is fixedly connected to the surface of the support cylinder 31 on the outer side of the right-angle plate 32.

[0034] Two support cylinders 31 are interlocked to form the central support shaft of the roll 3. Different lengths of support cylinders 31 can be replaced according to the winding width of the anode foil, adapting to winding operations of various foil widths. The two ends of the support cylinder 31 are inserted into the top groove of the right-angle plate 32 to achieve radial limiting, and the outer limiting ring 33 is tightly attached to the outer wall of the right-angle plate 32 to form axial limiting. During the operation of the roll 3, there will be no axial movement, the edge of the wound foil is neat, and the problems of winding misalignment and one-sided accumulation are avoided. The groove interlocking structure does not require additional locking bolts, and the disassembly and assembly of the roll 3 are simple, greatly improving the efficiency of roll changing.

[0035] A fixing plate 23 is fixedly connected to the upper end of the mounting frame 4. Support plates 24 are fixedly connected to both sides of the upper end of the fixing plate 23. A rectangular groove is formed on the surface of the support plate 24 facing downward. A sliding frame 25 that can move up and down is slidably connected inside the rectangular groove. A vertically arranged mounting screw 26 is threaded to the upper end of the support plate 24. The lower end of the mounting screw 26 is rotatably connected to the sliding frame 25. A transmission pulley 28 and a control knob 27 are fixedly connected to the upper end of the mounting screw 26. A synchronous belt is sleeved between the two transmission pulleys 28. The fixed plate 23 and the support plate 24 form the pressure roller adjustment support assembly. The sliding frame 25 slides vertically along the rectangular groove of the support plate 24 to achieve up-and-down adjustment. The synchronous belt links the transmission pulleys 28 on both sides. Turning the control knob 27 on one side will synchronously drive the two mounting screws 26 to rotate synchronously. Relying on the screw drive, the sliding frames 25 at both ends are raised and lowered synchronously, ensuring that the sliding frames 25 always remain horizontal and will not tilt with one end higher than the other. The adjustment operation can be completed by one person operating the knob on one side, which is convenient and labor-saving.

[0036] Two pressure rollers 29 are arranged vertically between the sliding frames 25. Each pressure roller 29 has a connecting gear 30 fixedly connected to its two ends. The vertically corresponding connecting gears 30 mesh with each other.

[0037] Two pressure rollers 29, one above the other, clamp the anode foil in pairs. A meshing gear 30 at both ends enables the two pressure rollers 29 to rotate synchronously in opposite directions. As the anode foil passes between the two pressure rollers 29, it is evenly compressed, and the friction of the rollers 29 pulls the foil for smooth transport. The gap between the two pressure rollers 29 can be adjusted via a lifting sliding frame 25 to accommodate anode foils of different thicknesses. Simultaneously, the continuous compression of the foil by the pressure rollers 29 eliminates wrinkles and looseness during the feeding process, ensuring uniform tension of the anode foil entering the sintering furnace 1 and improving the sintering quality. Working principle The anode foil to be sintered is first mounted on the drum 3 of the winding equipment. After being clamped and leveled by the upper and lower paired meshing pressure rollers 29, it is sent into the winding isolation device inside the vacuum sintering furnace 1. The winding isolation device drives the chain 18 to rotate cyclically through two sets of sprockets 17. The roller-type clamping structure arranged at intervals on the chain 18 evenly clamps the edge of the anode foil, separating the foil into layers and winding it between two sets of adjustable-gap winding discs to prevent the foil from sticking together. By rotating the adjustment knob 16, the adjustment screw 15, spline shaft 14 and support screw 11 are linked, and the spacing between the left and right winding discs can be adjusted synchronously to adapt to different... The wide anode foil is smoothly pulled into and out of the vacuum sintering furnace 1 by the guide slider 6 at the bottom of the horizontal plate 7 along the furnace guide rail 5, which facilitates material feeding and maintenance outside the furnace. After the anode foil is sintered at high temperature in the vacuum sintering furnace 1, the electric telescopic rod 34 of the winding equipment drives the swing frame 35 to flip downwards, and the roll 3 receives the sintered anode foil for winding. After winding, the swing frame 35 can be lowered again to quickly disassemble the roll 3. The whole set of equipment realizes continuous, isolated vacuum sintering and automatic winding of anode foil, ensuring uniform tension and consistent heating of foil throughout the process, and effectively preventing wrinkles, adhesion and deviation.
