Abstract
Description
Technical Field
[0001] The invention belongs to the technical field of foil splicing equipment, and in particular relates to a formed foil splicing operating table and a use method thereof, as well as a formed foil splicing device. Background Art
[0002] As a core raw material for aluminum electrolytic capacitors, formed foil plays a crucial role in the entire capacitor industry. Through sophisticated electrochemical treatment, its surface forms a nanoscale dielectric oxide film (Al2O3). This film possesses unique electrical properties, and its uniformity and density are directly related to several key performance indicators of aluminum electrolytic capacitors.
[0003] In the actual production of formed foil, a roll-to-roll continuous production process is typically used to meet the needs of large-scale, efficient production. This advanced process enables continuous electrochemical treatment of aluminum foil in roll form, significantly improving production efficiency and reducing production costs. However, there are certain limitations on the length of a single roll of aluminum foil, generally not exceeding 3,000 meters. After a roll of aluminum foil is processed, to maintain continuous operation of the production line and avoid production interruptions and reduced efficiency caused by downtime for roll changes, the two rolls must be connected through a foil splicing process to ensure smooth production.
[0004] Currently, the foil splicing process relies primarily on manual labor. The operator first carefully trims the top of the overlapping roll of foil into an arc, a step that requires significant manual skill and experience to ensure the required arc is achieved. Next, the tail of the previous roll is laid flat on the work surface, and the trimmed top of the next roll is precisely overlapped with the tail of the previous roll. This process requires precise control of the position and force of the overlap. The overlapping area is then manually smoothed to ensure a perfect fit between the two rolls. The overlapping area is then baked using a specialized baking device to achieve the required humidity. The baking time and temperature require the operator's experience to control. Finally, several hammer marks are manually applied to the overlapping area. The arrangement and number of hammer marks in each row depend entirely on the operator's prior experience and are determined visually.
[0005] This existing manual foil splicing method has numerous drawbacks. Firstly, the process is cumbersome and time-consuming, resulting in low production efficiency and difficulty meeting the demands of large-scale continuous production. Secondly, due to the lack of unified standards and specifications, different operators have different techniques and experience, resulting in inconsistent quality of the spliced aluminum foil, affecting the overall consistency and stability of the product.

Preferred embodiments of the present application will also be described. However, the present application can be implemented in many different forms and is not limited to the embodiments described herein.

[0024] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by those skilled in the art to which this application pertains. The terms used herein in the specification of this application are for the purpose of describing specific embodiments only and are not intended to limit this application. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.
[0025] Please see Figures 1 to 5In a specific embodiment, a chemical foil splicing operation table is used to overlap the tail of the previous roll of chemical foil and the head of the next roll of chemical foil. The chemical foil splicing operation table is located between the chemical foil winding roller and the chemical foil unwinding roller 100 on the chemical foil splicing device. The chemical foil winding roller is used to wind up the previous roll of chemical foil, and the chemical foil unwinding roller 100 is used to convey the next roll of chemical foil. The chemical foil splicing operation table includes a placement table 200. The platform 200 is arranged between the chemical foil winding roller and the chemical foil unwinding roller 100. The platform 200 is provided with an alignment component 300, a flattening component 400, a cutting component 500, a heating component and a hammer marking component 600. The alignment component 300 is arranged on both sides of the platform 200 to align the overlapped area formed by the overlapped tail of the previous roll of chemical foil and the overlapped head of the next roll of chemical foil; the flattening component 400 is located on the Any end of the placement table 200, and at a preset height from the placement table 200, and can be moved along one end of the placement table 200 to the other end of the placement table 200, for smoothing the overlapping area; the cutting component 500 is located on the placement table 200 and close to one end of the chemical foil unwinding roller 100, and the cutting component 500 has a preset shape, which is used to assist the operator to cut the head of the next roll of chemical foil into a specified shape; the heating component is arranged in the placement table 200, for heating the overlapping area and controlling the humidity of the chemical foil in the overlapping area to a predetermined humidity; the hammer mark component 600 is located above the placement table 200, for generating hammer marks and projecting them onto the overlapping area, and the hammering personnel knocks according to the hammer marks on the overlapping area to complete the overlap of the tail of the previous roll of chemical foil and the head of the next roll of chemical foil.
[0026] When the chemical foil splicing operation table provided in this embodiment is used, first, the operator places the chemical foil splicing operation table between the chemical foil winding roller and the chemical foil unwinding roller 100 on the chemical foil splicing device. At this time, the previous roll of chemical foil is on the winding roller, and the next roll of chemical foil is on the unwinding roller waiting to be transported; then, the tail of the previous roll of chemical foil is laid flat on the placement table 200, and the head of the next roll of chemical foil is overlapped with the tail of the previous roll of chemical foil to form an overlap area, and then the alignment components 3 on both sides of the placement table 200 are used to align the two rolls of chemical foil. 00, align the overlapping area to ensure that the two rolls of formed foil are accurately overlapped to avoid insufficient tension of the finished product due to misalignment of the overlap, which is easy to tear; next, start the flattening component 400 located at either end of the placement table 200 and at a preset height from the placement table 200, which can move from one end of the placement table 200 to the other end, and make it move from one end of the placement table 200 to the other end. It should be noted that: the flattening component 400 is tightly attached to the overlapping area when moving, so that the overlapping area can be smoothed during the movement, so that the two rolls of formed foil are accurately overlapped. The foil is fully fitted; then, the operator adjusts the cutting assembly 500 to descend to the head of the next roll of formed foil and presses it tightly on the head of the roll. Using the preset shape of the cutting assembly 500, the operator can tear off the excess formed foil. In this application, the cutting assembly 500 has an arc-shaped edge with a preset curvature, which can cut the head of the next roll of formed foil into an arc-shaped edge; then, the heating assembly provided in the placement table 200 is turned on to heat the overlapping area and control the humidity of the formed foil in the overlapping area to a predetermined humidity to meet the requirements of subsequent processes. In this embodiment, the heating component can be an electric heating wire, and the electric heating wire coil can be placed in the placement table 200, and the control switch for starting the electric heating wire is left outside the placement table 200 to facilitate the operator to start or shut down; finally, the hammer mark component 600 above the placement table 200 is used to generate a hammer mark, and it is projected onto the overlapping area to provide a standard hammer mark position. The hammering personnel knocks according to the hammer mark on the overlapping area to complete the overlap of the tail of the previous roll of formed foil and the head of the next roll of formed foil.
[0027] The operating table integrates multiple functional components such as cutting, alignment, flattening, heating and hammer marking. Operators can complete multiple key steps of foil splicing in sequence on one platform, avoiding the time waste of transferring aluminum foil between different equipment or areas, greatly improving the overall efficiency of foil splicing, and providing standardized operating procedures and tools for the foil splicing process. Operators only need to follow the instructions of the operating table to perform the operations in sequence, reducing the dependence on the operator's personal skills and experience, making the foil splicing operation more standardized and unified, and making the foil splicing quality of each roll of chemical foil more consistent, thereby improving the product consistency of aluminum electrolytic capacitors produced based on these chemical foils and reducing product performance fluctuations.
[0028] Furthermore, the alignment assembly 300 includes a double reverse threaded screw 310, a pair of threaded clamping blocks 320 and a handwheel 330. The double reverse threaded screw 310 can be rotatably arranged on both sides of the placement table 200, and a pair of the threaded clamping blocks are respectively arranged on the threads at both ends of the double reverse threaded screw 310. The handwheel 330 is arranged at one end of the double reverse threaded screw 310, and is used to rotate the double reverse threaded screw 310 to make the pair of threaded clamping blocks move toward each other or away from each other, and are used to align the overlapping area when moving toward each other.
[0029] When it is necessary to align the two sides of the overlap area formed by the overlap of the tail of the previous roll of chemical foil and the head of the next roll of chemical foil, the operator first goes to the side of the placement table 200 of the chemical foil connection operation table, finds the handwheel 330 on the double-reverse threaded screw 310 set on the side of the placement table 200, and the operator holds the handwheel 330 with his hand and rotates the handwheel 330 clockwise or counterclockwise according to the actual situation of the overlap area. Because the handwheel 330 is connected to the double-reverse threaded screw 310, rotating the handwheel 330 will drive the double-reverse threaded screw 310 to rotate. When the double-reverse threaded screw 310 rotates, the design of the different thread directions at its two ends causes a pair of thread clamping blocks 320 respectively set on the threads at the two ends of the double-reverse threaded screw 310 to move toward each other. That is, one thread clamping block moves along the screw toward the other thread clamping block, and the same applies to the other thread clamping block. As the pair of threaded clamping blocks 320 move toward each other, they gradually approach the overlap area, clamping and pushing the formed foil on both sides of the overlap area to accurately align the two sides of the overlap area. When the ideal alignment is achieved, stop turning the handwheel 330. To loosen the alignment, turn the handwheel 330 in the opposite direction, moving the pair of threaded clamping blocks 320 away from each other and out of the overlap area.
[0030] The main function of the alignment component 300 is to ensure that the two sides of the overlapping area can be accurately aligned. If the overlapping area is not aligned, it may cause the overlapping area to be easily torn in subsequent processes.
[0031] Furthermore, the leveling assembly 400 includes a pair of fixed rods 410, a sliding connecting rod 420, a leveling roller 430 and a handle 440. The pair of fixed rods 410 are respectively arranged on both sides of the placement table 200 and have a predetermined distance from the placement table 200. One end of the sliding connecting rod 420 is slidably set on one of the fixed rods, and the other end of the sliding connecting rod 420 is slidably set on another fixed rod. The leveling roller 430 can be rotatably set on the sliding connecting rod 420. The handle 440 is set on either end of the sliding connecting rod 420. When the sliding connecting rod 420 is pushed from one end of the placement table 200 to the other end, the leveling roller 430 rotates to smooth the overlapping area.
[0032] The operator grasps the handle 440 and steadily pushes the sliding connecting rod 420 along the length of the platform 200, from one end to the other (the leveling assembly 400 is in its initial position before operation). During this pushing process, the leveling roller 430 rolls as the sliding connecting rod 420 moves, due to the sliding connection between the sliding connecting rod 420 and the fixed rod, and the rotatable connection between the leveling roller 430 and the sliding connecting rod 420. When the operator pushes the sliding connecting rod 420 to the other end of the platform 200, the leveling roller 430 has completed rolling and smoothing the entire overlapping area. At this point, the handle 440 is released, completing the leveling process. If the leveling effect is not satisfactory, the above pushing operation can be repeated until the overlapping area reaches a satisfactory level. It should be noted that during use, the leveling roller 430 is in close contact with the overlapping area.
[0033] During the overlapping process, the two rolls of chemical foil may be wrinkled or uneven. The rolling of the smoothing roller 430 can apply a certain pressure to make the chemical foils in the overlapping area fully fit together, eliminate wrinkles and unevenness, and ensure the overlapping quality.
[0034] The use of the flattening assembly 400 can effectively improve the flatness of the overlapping area, so that the quality of the subsequently formed oxide film is higher, thereby improving the overall quality of the aluminum electrolytic capacitors produced based on these formed foils.
[0035] Furthermore, the cutting assembly 500 includes an arc-shaped pressure plate 510 and a height adjustment member 520. The arc-shaped pressure plate 510 has an arc-shaped edge. The height adjustment member 520 passes through the arc-shaped pressure plate 510 to fix it on the placement table 200 and is used to adjust the height of the arc-shaped pressure plate 510 on the placement table 200.
[0036] The operator adjusts the height of the curved pressing plate 510 above the placement table 200 by operating the height adjustment member 520 (the height adjustment member 520 may be a bolt and nut structure. The bolt passes vertically through the curved pressing plate 510 and is secured in a pre-set threaded hole in the placement table 200. Rotating the nut changes the distance between the curved pressing plate 510 and the placement table 200). Adjusting the curved pressing plate 510 to the appropriate height ensures that when the next roll of formed foil is placed on the placement table 200 for cutting, the curved edge of the curved pressing plate 510 accurately presses against the formed foil, forming the desired cutting contour. Because the curved pressing plate 510 provides a clearly defined curved contour, the operator can easily tear off excess formed foil along the curved edge of the curved pressing plate 510.
[0037] The cutting assembly 500 can significantly improve the cutting accuracy of the head of the next rolled foil roll. Since the cutting operation becomes simple and quick, the operator can complete the cutting steps more quickly, reducing time waste in the cutting process and improving work efficiency.
[0038] Furthermore, the hammer mark assembly 600 includes an adjusting screw 610, an adjusting bracket 620 and a hammer mark projection light board 630. The adjusting screw 610 is arranged on the placement table 200 and is rotatably connected to the placement table 200. One end of the adjusting bracket 620 is arranged on the thread of the adjusting screw 610. The hammer mark projection light board 630 is arranged on the other end of the adjusting bracket 620. A plurality of hollow hammer marks in a predetermined arrangement are arranged on the lower plate surface of the hammer mark projection light board 630. A light emitter is arranged in the hammer mark projection light board 630. When the light emitter is activated, light passes through the hollow hammer marks and projects a plurality of hammer mark marks onto the overlapping area on the placement table 200.
[0039] It should be noted that: before use, the adjusting screw 610 has been firmly set on the placement table 200 and can be rotated, one end of the adjusting bracket 620 is installed on the thread of the adjusting screw 610, and the hammer projection light board 630 is fixed to the other end of the adjusting bracket 620. And the light emitter in the hammer projection light board 630 is in the off state. When in use: First, according to the specific position of the overlapping area on the placement table 200, adjust the hammer projection light board 630 to the appropriate position to ensure that it is located directly above the overlapping area so that the hammer projection can accurately cover the overlapping area. When the position of the hammer projection light board 630 is adjusted, the operator turns on the light emitter in the hammer projection light board 630. The light emitter emits light, which passes through a number of hollow hammer marks arranged in a predetermined arrangement on the lower surface of the hammer projection light board 630, projecting a number of hammer marks on the overlapping area on the placement table 200. The hammering operator uses a suitable tool (such as a plum blossom hammer) to perform a hammering operation based on the hammer marks projected on the overlapping area, firmly overlapping the tail of the previous roll of chemical foil and the head of the next roll of chemical foil. After the hammering operation is completed, the operator turns off the light emitter, completing the hammer marking and knocking operation process. It should be noted that the hollow hammer marks on the hammer projection light board 630 in this embodiment are specially arranged. Under this arrangement, the tension of the overlapping chemical foil is greater and it is not easy to tear. The specific arrangement can be seen in the attached figure.
[0040] The hollow hammer marks on the lower surface of the hammer projection light board 630 are arranged in a predetermined manner. After the light passes through these hollow hammer marks, clear and accurate hammer marks can be projected in the overlapping area. These marks provide clear indications of the knocking position for the hammering personnel, ensuring that the knocking operation is accurate and correct, which helps to improve the quality and stability of the foil joints. Compared with the traditional method of manually marking the hammer position on the chemical foil, the hammer mark assembly 600 uses light projection to complete the marking work more quickly and conveniently. The operator only needs to adjust the position of the light board and turn on the light emitter, which greatly simplifies the operation process and improves work efficiency. Due to the accuracy and consistency of the hammer mark, the foil joint position and knocking force of each roll of chemical foil can be better controlled, ensuring the stability of product quality. In the mass production process, more consistent quality products can be produced.
[0041] Furthermore, four rows of hollow hammer marks are arranged on the lower plate surface of the hammer mark projection light board 630, wherein the curvature of the first row of hollow hammer marks composed of first hollow hammer marks is consistent with the curvature of the curvature of the front end of the scroll head, and a second number of hollow hammer marks are arranged below the first row of hollow hammer marks, staggered with the first row of hollow hammer marks, to form a second row of hollow hammer marks, the second number is smaller than the first number, and the curvature of the second row of hollow hammer marks is smaller than the curvature of the first row of hollow hammer marks; the second number of hollow hammer marks are arranged below the second row of hollow hammer marks, staggered with the second row of hollow hammer marks, to form a third row of hollow hammer marks, the curvature of the third row of hollow hammer marks is smaller than the curvature of the second row of hollow hammer marks; the third number of hollow hammer marks are arranged below the third row of hollow hammer marks, staggered with the third row of hollow hammer marks, to form a fourth row of hollow hammer marks, and the fourth row of hollow hammer marks is arranged in a straight line.
[0042] For example, the arc radius of the front end of the roll head of the last roll of formed foil is 10 cm. The first row of hollow hammer marks consists of 15 hollow hammer marks, and their arc is consistent with the arc of the front end of the roll head, that is, they are arranged in an arc with a radius of about 10 cm. The second row of hollow hammer marks consists of 14 hollow hammer marks, which are offset from the first row and arranged in an arc with a radius of about 8 cm. The third row of hollow hammer marks also consists of 14 hollow hammer marks, which are offset from the second row and arranged in an arc with a radius of about 6 cm. The fourth row of hollow hammer marks consists of 12 hollow hammer marks, which are arranged in a straight line below the third row of hollow hammer marks. The hammer mark projection light board 630 can be rectangular, and the hollow hammer marks on the lower panel can be made by laser cutting technology to ensure that the shape and position of each hollow hammer mark are accurate. The light emitter can use a high-brightness LED light group, which can provide sufficient and uniform light to make the hammer mark clearly visible.
[0043] The hammering technician uses a suitable tool (such as a plum blossom hammer) to hammer the marks, starting from the first row to the fourth row, according to the hammer mark pattern projected onto the overlapped area. They first hammer along the first row of hollow hammer marks, which align with the arc of the front end of the roll. Then they hammer along the second and third rows of hollow hammer marks, which are arranged in an offset pattern. Finally, they hammer along the fourth row of hollow hammer marks, which are arranged in a straight line, to firmly join the two rolls of foil together.
[0044] In this way, a first number (for example, 15) of hammer marks are struck on the arc edge of the roll head to form a first row of hammer marks that is consistent with the arc of the front end of the roll head, which mainly provides a starting basis for connecting subsequent multiple rows of hammer marks, and at the same time preliminarily fixes the relative positions of the roll head and the roll tail, and the distribution of hammer marks along the arc edge can adapt to the shape of the roll head, so that the stress begins to disperse in the arc area; below the first row of hammer marks, a second row of hammer marks with a smaller number (for example, 14) and a smaller arc are struck, which is offset from the first row of hammer marks. Since the arc of the second row of hammer marks is smaller than that of the first row of hammer marks, the stress distribution in the longitudinal direction of the roll head is more reasonable, forming a gradual stress dispersion pattern; below the second row of hammer marks, a third row of hammer marks with a second number (for example, 14) and a smaller arc are struck, which is offset from the second row of hammer marks. Hammer marks further increase the connection points and connection areas, improve the ability of the roll head to resist external forces, reduce the possibility of loosening or separation due to external forces, and further refine the stress transfer path through smaller arcs and staggered arrangements, so that the stress can be more evenly distributed in various parts of the roll head; a fourth row of hammer marks of the third number (for example: 12) is struck below the third row of hammer marks and staggered with the third row of hammer marks, and the fourth row of hammer marks is arranged in a straight line, which can adjust the local stress in the area close to the right-angled side of the roll tail, and can be combined with the rows of arc hammer marks above to form a three-dimensional stress dispersion network. When the roll head is subjected to external force, the stress can be transmitted and dispersed in the entire roll head through the network composed of arc hammer marks and straight hammer marks, thereby effectively reducing the possibility of stress concentration and deformation.
[0045] Operators can quickly and accurately perform hammering operations based on the hammer marks, eliminating the need to spend a significant amount of time determining the hammering positions. This shortens the time required for foil splicing and improves the overall efficiency of the formed foil splicing process. The clearly defined arrangement of the hammer marks makes the hammering and tapping operations more standardized, reducing fluctuations in foil splicing quality due to differences in operator skill levels, enhancing the stability of the production process, and ensuring product quality consistency. Furthermore, because the curvature of the first row of hammer marks matches the arc shape, stress can be evenly transferred along the arc when subjected to external force, avoiding stress concentration at the arc edge. The smaller curvature and fewer connection points of the second row of hammer marks ensure a more even distribution of stress during expansion and contraction, reducing the possibility of fracture due to localized stress concentration. The further reduced curvature of the third row of hammer marks further refines the stress transfer path, enabling a more even distribution of stress across the coil head. The fourth row of hammer marks is arranged in a straight line, adjusting local stress near the right-angled edge at the coil tail, resulting in a more balanced stress distribution across the entire overlap area and preventing tearing.
[0046] In a preferred embodiment, the placement table 200 is further provided with a blowing mechanism for blowing away impurities on the placement table 200 .
[0047] During the foil splicing process, impurities such as dust, metal debris, and fibers may accumulate on the placement platform 200. If these impurities adhere to the overlapping area of the formed foils, the subsequent electrochemical treatment can lead to uneven oxide film growth and localized weak spots. The impurity blowing mechanism effectively removes impurities from the placement platform 200, ensuring a clean overlapping area and forming a uniform oxide film.
[0048] The present application also provides a method for using a foil forming and foil joining operation table, comprising the following steps: S10. The formed foil jointing operation station is provided between the formed foil reel and the formed foil unwinding roller 100 on the formed foil jointing device; S20. The tail portion of the previous roll of the formed foil is placed on the placement table 200, and the unwinding roll 100 conveys the formed foil to overlap the head portion of the roll of the foil after the roll is overlapped on the tail portion to form an overlap area; S30. Turn the handwheel 330 so that the double reverse threaded screw 310 drives the pair of threaded clamping blocks to move toward each other so that the roll head and roll tail of the overlap area are aligned. After alignment, rotate the first wheel in the opposite direction so that the double reverse threaded screw 310 drives the pair of threaded clamping blocks to move away from each other and return to their initial positions. S40. Pushing the sliding connecting rod 420 along one end of the placement table 200 toward the other end, the leveling roller 430 rotates to smooth the overlapping area; S50. Use the height adjuster 520 to adjust the curved pressure plate 510 to a preset height, ensuring it rests firmly on the head of the next roll of formed foil. The operator then tears off the excess portion of the head of the next roll of formed foil along the curved edge of the curved plate, creating a curved edge at the head of the next roll of formed foil. S60 starts the heating component to heat the overlap area so that the humidity of the overlap area is less than 10%; S70. Turn the adjusting screw 610 to adjust the hammer projection light panel 630 to the predetermined position, start the light emitter, and the light passes through the hollow hammer mark to project a number of hammer marks onto the overlapping area on the placement table 200. The hammering personnel knock according to the hammer marks on the overlapping area to complete the overlap of the tail of the previous roll of formed foil and the head of the next roll of formed foil.
[0049] When using this operating table to splice aluminum foil, the operator can complete multiple key steps of foil splicing in sequence on one platform, avoiding the time wasted in transferring aluminum foil between different equipment or areas, greatly improving the overall efficiency of foil splicing, and providing standardized operating procedures and tools for the foil splicing process. The operator only needs to follow the instructions of the operating table to perform the operations in sequence, reducing the dependence on the operator's personal skills and experience, making the foil splicing operation more standardized and unified, and making the foil splicing quality of each roll of chemical foil more consistent, thereby improving the product consistency of aluminum electrolytic capacitors produced based on these chemical foils and reducing fluctuations in product performance.
[0050] In a preferred embodiment, the step S70 specifically includes the following steps: S71. According to the hammer mark, the first number (15) of hammer marks are struck sequentially from the middle of the curved edge of the volume head to both sides; S72. Strike a second number (14) of hammer marks from left to right below the first row of hammer marks and offset from the first row of hammer marks according to the hammer marks; S73. According to the hammer mark, the second number (14) of hammer marks are struck from right to left below the second row of hammer marks and offset from the second row of hammer marks; S74. According to the hammer mark, strike the third number (12) of hammer marks in sequence from the middle to both sides below the third row of hammer marks and offset from the third row of hammer marks.
[0051] The hammering sequence, from the center outwards and alternating left and right, ensures more uniform and coordinated expansion and contraction deformation at the foil joint. When the formed foil expands and contracts during production, stress is distributed and distributed in an orderly manner along the distribution of hammer marks. For example, hammering from the center allows the expansion and contraction to spread from the center outwards, avoiding stress concentration at one end or in a localized area. Alternating left and right hammering further enhances this coordination. This allows the foil joint to better adapt to expansion and contraction changes, reducing stress concentration and fracture caused by uncoordinated expansion and contraction, and further improving expansion and contraction performance.
[0052] The present application also provides a chemical foil splicing device, including a chemical foil winding roller and a chemical foil unwinding roller 100, the chemical foil winding roller is used to wind up the previous roll of chemical foil, and the chemical foil unwinding roller 100 is used to convey the next roll of chemical foil, and also includes a chemical foil splicing operation table, which is used to overlap the roll tail of the previous roll of chemical foil and the roll head of the next roll of chemical foil. The chemical foil splicing operation table is located between the chemical foil winding roller and the chemical foil unwinding roller 100 on the chemical foil splicing device. The foil splicing operation table includes a placement table 200, which is arranged between the chemical foil winding roller and the chemical foil unwinding roller 100. The placement table 200 is provided with an alignment component 300, a flattening component 400, a cutting component 500, a heating component and a hammer marking component 600. The alignment component 300 is arranged on both sides of the placement table 200, and is used to align the overlapping area formed by overlapping the tail of the previous roll of chemical foil and the head of the next roll of chemical foil; The flattening component 400 is located at either end of the placement table 200 and has a preset height from the placement table 200, and can be moved along one end of the placement table 200 to the other end of the placement table 200 to smooth the overlapping area; the cutting component 500 is located on the placement table 200 and close to one end of the chemical foil unwinding roller 100. The cutting component 500 has a preset shape to assist the operator in cutting the head of the next roll of chemical foil into a specified shape; the heating component is arranged in the placement table 200 to heat the overlapping area and control the humidity of the chemical foil in the overlapping area to a predetermined humidity; the hammer mark component 600 is located above the placement table 200 to generate a hammer mark and project it onto the overlapping area. The hammering personnel knocks according to the hammer mark on the overlapping area to complete the overlap of the tail of the previous roll of chemical foil and the head of the next roll of chemical foil.
[0053] The operating table in the chemical foil splicing device provided in the present application integrates multiple functional components such as cutting, alignment, flattening, heating and hammer marking. The operator can complete multiple key steps of foil splicing in sequence on one platform, avoiding the time waste of transferring aluminum foil between different equipment or areas, greatly improving the overall efficiency of foil splicing, and providing standardized operating procedures and tools for the foil splicing process. The operator only needs to follow the instructions of the operating table to perform the operations in sequence, reducing the dependence on the operator's personal skills and experience, making the foil splicing operation more standardized and unified, and making the splicing quality of each roll of chemical foil more consistent, thereby improving the product consistency of aluminum electrolytic capacitors produced based on these chemical foils and reducing fluctuations in product performance.
[0054] Furthermore, the alignment assembly 300 includes a double reverse threaded screw 310, a pair of threaded clamping blocks 320 and a handwheel 330. The double reverse threaded screw 310 can be rotatably arranged on both sides of the placement table 200, and a pair of the threaded clamping blocks are respectively arranged on the threads at both ends of the double reverse threaded screw 310. The handwheel 330 is arranged at one end of the double reverse threaded screw 310, and is used to rotate the double reverse threaded screw 310 to make the pair of threaded clamping blocks move toward each other or away from each other, and are used to align the overlapping area when moving toward each other.
[0055] When it is necessary to align the two sides of the overlap area formed by the overlap of the tail of the previous roll of chemical foil and the head of the next roll of chemical foil, the operator first goes to the side of the placement table 200 of the chemical foil connection operation table, finds the handwheel 330 on the double-reverse threaded screw 310 set on the side of the placement table 200, and the operator holds the handwheel 330 with his hand and rotates the handwheel 330 clockwise or counterclockwise according to the actual situation of the overlap area. Because the handwheel 330 is connected to the double-reverse threaded screw 310, rotating the handwheel 330 will drive the double-reverse threaded screw 310 to rotate. When the double-reverse threaded screw 310 rotates, the design of the different thread directions at its two ends causes a pair of thread clamping blocks 320 respectively set on the threads at the two ends of the double-reverse threaded screw 310 to move toward each other. That is, one thread clamping block moves along the screw toward the other thread clamping block, and the same applies to the other thread clamping block. As the pair of threaded clamping blocks 320 move toward each other, they gradually approach the overlap area, clamping and pushing the formed foil on both sides of the overlap area to accurately align the two sides of the overlap area. When the ideal alignment is achieved, stop turning the handwheel 330. To loosen the alignment, turn the handwheel 330 in the opposite direction, moving the pair of threaded clamping blocks 320 away from each other and out of the overlap area.
[0056] The main function of the alignment component 300 is to ensure that the two sides of the overlapping area can be accurately aligned. If the overlapping area is not aligned, it may cause the overlapping area to be easily torn in subsequent processes.
[0057] Furthermore, the leveling assembly 400 includes a pair of fixed rods 410, a sliding connecting rod 420, a leveling roller 430 and a handle 440. The pair of fixed rods 410 are respectively arranged on both sides of the placement table 200 and have a predetermined distance from the placement table 200. One end of the sliding connecting rod 420 is slidably set on one of the fixed rods, and the other end of the sliding connecting rod 420 is slidably set on another fixed rod. The leveling roller 430 can be rotatably set on the sliding connecting rod 420. The handle 440 is set on either end of the sliding connecting rod 420. When the sliding connecting rod 420 is pushed from one end of the placement table 200 to the other end, the leveling roller 430 rotates to smooth the overlapping area.
[0058] The operator grasps the handle 440 and steadily pushes the sliding connecting rod 420 along the length of the platform 200, from one end to the other (the leveling assembly 400 is in its initial position before operation). During this pushing process, the leveling roller 430 rolls as the sliding connecting rod 420 moves, due to the sliding connection between the sliding connecting rod 420 and the fixed rod, and the rotatable connection between the leveling roller 430 and the sliding connecting rod 420. When the operator pushes the sliding connecting rod 420 to the other end of the platform 200, the leveling roller 430 has completed rolling and smoothing the entire overlapping area. At this point, the handle 440 is released, completing the leveling process. If the leveling effect is not satisfactory, the above pushing operation can be repeated until the overlapping area reaches a satisfactory level. It should be noted that during use, the leveling roller 430 is in close contact with the overlapping area.
[0059] During the overlapping process, the two rolls of chemical foil may be wrinkled or uneven. The rolling of the smoothing roller 430 can apply a certain pressure to make the chemical foils in the overlapping area fully fit together, eliminate wrinkles and unevenness, and ensure the overlapping quality.
[0060] The use of the flattening assembly 400 can effectively improve the flatness of the overlapping area, so that the quality of the subsequently formed oxide film is higher, thereby improving the overall quality of the aluminum electrolytic capacitors produced based on these formed foils.
[0061] Furthermore, the cutting assembly 500 includes an arc-shaped pressure plate 510 and a height adjustment member 520. The arc-shaped pressure plate 510 has an arc-shaped edge. The height adjustment member 520 passes through the arc-shaped pressure plate 510 to fix it on the placement table 200 and is used to adjust the height of the arc-shaped pressure plate 510 on the placement table 200.
[0062] The operator adjusts the height of the curved pressing plate 510 above the placement table 200 by operating the height adjustment member 520 (the height adjustment member 520 may be a bolt and nut structure. The bolt passes vertically through the curved pressing plate 510 and is secured in a pre-set threaded hole in the placement table 200. Rotating the nut changes the distance between the curved pressing plate 510 and the placement table 200). Adjusting the curved pressing plate 510 to the appropriate height ensures that when the next roll of formed foil is placed on the placement table 200 for cutting, the curved edge of the curved pressing plate 510 accurately presses against the formed foil, forming the desired cutting contour. Because the curved pressing plate 510 provides a clearly defined curved contour, the operator can easily tear off excess formed foil along the curved edge of the curved pressing plate 510.
[0063] The cutting assembly 500 can significantly improve the cutting accuracy of the head of the next rolled foil roll. Since the cutting operation becomes simple and quick, the operator can complete the cutting steps more quickly, reducing time waste in the cutting process and improving work efficiency.
[0064] Furthermore, the hammer mark assembly 600 includes an adjusting screw 610, an adjusting bracket 620 and a hammer mark projection light board 630. The adjusting screw 610 is arranged on the placement table 200 and is rotatably connected to the placement table 200. One end of the adjusting bracket 620 is arranged on the thread of the adjusting screw 610. The hammer mark projection light board 630 is arranged on the other end of the adjusting bracket 620. A plurality of hollow hammer marks in a predetermined arrangement are arranged on the lower plate surface of the hammer mark projection light board 630. A light emitter is arranged in the hammer mark projection light board 630. When the light emitter is activated, light passes through the hollow hammer marks and projects a plurality of hammer mark marks onto the overlapping area on the placement table 200.
[0065] It should be noted that: before use, the adjusting screw 610 has been firmly set on the placement table 200 and can be rotated, one end of the adjusting bracket 620 is installed on the thread of the adjusting screw 610, and the hammer projection light board 630 is fixed to the other end of the adjusting bracket 620. And the light emitter in the hammer projection light board 630 is in the off state. When in use: First, according to the specific position of the overlapping area on the placement table 200, adjust the hammer projection light board 630 to the appropriate position to ensure that it is located directly above the overlapping area so that the hammer projection can accurately cover the overlapping area. When the position of the hammer projection light board 630 is adjusted, the operator turns on the light emitter in the hammer projection light board 630. The light emitter emits light, which passes through a number of hollow hammer marks arranged in a predetermined arrangement on the lower surface of the hammer projection light board 630, projecting a number of hammer marks on the overlapping area on the placement table 200. The hammering operator uses a suitable tool (such as a plum blossom hammer) to perform a hammering operation based on the hammer marks projected on the overlapping area, firmly overlapping the tail of the previous roll of chemical foil and the head of the next roll of chemical foil. After the hammering operation is completed, the operator turns off the light emitter, completing the hammer marking and knocking operation process. It should be noted that the hollow hammer marks on the hammer projection light board 630 in this embodiment are specially arranged. Under this arrangement, the tension of the overlapping chemical foil is greater and it is not easy to tear. The specific arrangement can be seen in the attached figure.
[0066] The hollow hammer marks on the lower surface of the hammer projection light board 630 are arranged in a predetermined manner. After the light passes through these hollow hammer marks, clear and accurate hammer marks can be projected in the overlapping area. These marks provide clear indications of the knocking position for the hammering personnel, ensuring that the knocking operation is accurate and correct, which helps to improve the quality and stability of the foil joints. Compared with the traditional method of manually marking the hammer position on the chemical foil, the hammer mark assembly 600 uses light projection to complete the marking work more quickly and conveniently. The operator only needs to adjust the position of the light board and turn on the light emitter, which greatly simplifies the operation process and improves work efficiency. Due to the accuracy and consistency of the hammer mark, the foil joint position and knocking force of each roll of chemical foil can be better controlled, ensuring the stability of product quality. In the mass production process, more consistent quality products can be produced.
[0067] Furthermore, four rows of hollow hammer marks are arranged on the lower plate surface of the hammer mark projection light board 630, wherein the curvature of the first row of hollow hammer marks composed of first hollow hammer marks is consistent with the curvature of the curvature of the front end of the scroll head, and a second number of hollow hammer marks are arranged below the first row of hollow hammer marks, staggered with the first row of hollow hammer marks, to form a second row of hollow hammer marks, the second number is smaller than the first number, and the curvature of the second row of hollow hammer marks is smaller than the curvature of the first row of hollow hammer marks; the second number of hollow hammer marks are arranged below the second row of hollow hammer marks, staggered with the second row of hollow hammer marks, to form a third row of hollow hammer marks, the curvature of the third row of hollow hammer marks is smaller than the curvature of the second row of hollow hammer marks; the third number of hollow hammer marks are arranged below the third row of hollow hammer marks, staggered with the third row of hollow hammer marks, to form a fourth row of hollow hammer marks, and the fourth row of hollow hammer marks is arranged in a straight line.
[0068] For example, the arc radius of the front end of the roll head of the last roll of formed foil is 10 cm. The first row of hollow hammer marks consists of 15 hollow hammer marks, and their arc is consistent with the arc of the front end of the roll head, that is, they are arranged in an arc with a radius of about 10 cm. The second row of hollow hammer marks consists of 14 hollow hammer marks, which are offset from the first row and arranged in an arc with a radius of about 8 cm. The third row of hollow hammer marks also consists of 14 hollow hammer marks, which are offset from the second row and arranged in an arc with a radius of about 6 cm. The fourth row of hollow hammer marks consists of 12 hollow hammer marks, which are arranged in a straight line below the third row of hollow hammer marks. The hammer mark projection light board 630 can be rectangular, and the hollow hammer marks on the lower panel can be made by laser cutting technology to ensure that the shape and position of each hollow hammer mark are accurate. The light emitter can use a high-brightness LED light group, which can provide sufficient and uniform light to make the hammer mark clearly visible.
[0069] The hammering technician uses a suitable tool (such as a plum blossom hammer) to hammer the marks, starting from the first row to the fourth row, according to the hammer mark pattern projected onto the overlapped area. They first hammer along the first row of hollow hammer marks, which align with the arc of the front end of the roll. Then they hammer along the second and third rows of hollow hammer marks, which are arranged in an offset pattern. Finally, they hammer along the fourth row of hollow hammer marks, which are arranged in a straight line, to firmly join the two rolls of foil together.
[0070] In this way, a first number (for example, 15) of hammer marks are struck on the arc edge of the roll head to form a first row of hammer marks that is consistent with the arc of the front end of the roll head, which mainly provides a starting basis for connecting subsequent multiple rows of hammer marks, and at the same time preliminarily fixes the relative positions of the roll head and the roll tail, and the distribution of hammer marks along the arc edge can adapt to the shape of the roll head, so that the stress begins to disperse in the arc area; below the first row of hammer marks, a second row of hammer marks with a smaller number (for example, 14) and a smaller arc are struck, which is offset from the first row of hammer marks. Since the arc of the second row of hammer marks is smaller than that of the first row of hammer marks, the stress distribution in the longitudinal direction of the roll head is more reasonable, forming a gradual stress dispersion pattern; below the second row of hammer marks, a third row of hammer marks with a second number (for example, 14) and a smaller arc are struck, which is offset from the second row of hammer marks. Hammer marks further increase the connection points and connection areas, improve the ability of the roll head to resist external forces, reduce the possibility of loosening or separation due to external forces, and further refine the stress transfer path through smaller arcs and staggered arrangements, so that the stress can be more evenly distributed in various parts of the roll head; a fourth row of hammer marks of the third number (for example: 12) is struck below the third row of hammer marks and staggered with the third row of hammer marks, and the fourth row of hammer marks is arranged in a straight line, which can adjust the local stress in the area close to the right-angled side of the roll tail, and can be combined with the rows of arc hammer marks above to form a three-dimensional stress dispersion network. When the roll head is subjected to external force, the stress can be transmitted and dispersed in the entire roll head through the network composed of arc hammer marks and straight hammer marks, thereby effectively reducing the possibility of stress concentration and deformation.
[0071] Operators can quickly and accurately perform hammering operations based on the hammer marks, eliminating the need to spend a significant amount of time determining the hammering positions. This shortens the time required for foil splicing and improves the overall efficiency of the formed foil splicing process. The clearly defined arrangement of the hammer marks makes the hammering and tapping operations more standardized, reducing fluctuations in foil splicing quality due to differences in operator skill levels, enhancing the stability of the production process, and ensuring product quality consistency. Furthermore, because the curvature of the first row of hammer marks matches the arc shape, stress can be evenly transferred along the arc when subjected to external force, avoiding stress concentration at the arc edge. The smaller curvature and fewer connection points of the second row of hammer marks ensure a more even distribution of stress during expansion and contraction, reducing the possibility of fracture due to localized stress concentration. The further reduced curvature of the third row of hammer marks further refines the stress transfer path, enabling a more even distribution of stress across the coil head. The fourth row of hammer marks is arranged in a straight line, adjusting local stress near the right-angled edge at the coil tail, resulting in a more balanced stress distribution across the entire overlap area and preventing tearing.
[0072] In a preferred embodiment, the placement table 200 is further provided with a blowing mechanism for blowing away impurities on the placement table 200 .
[0073] During the foil splicing process, impurities such as dust, metal debris, and fibers may accumulate on the placement platform 200. If these impurities adhere to the overlapping area of the formed foils, the subsequent electrochemical treatment can lead to uneven oxide film growth and localized weak spots. The impurity blowing mechanism effectively removes impurities from the placement platform 200, ensuring a clean overlapping area and forming a uniform oxide film.
[0074] The above description is only a specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any technician familiar with this technical field can easily think of various equivalent modifications or replacements within the technical scope disclosed by the present invention, and these modifications or replacements should all be included in the scope of protection of the present invention.
