Description

Technical Field

[0001] This utility model belongs to the technical field of foil splicing equipment, specifically relating to a foil splicing operating table and a foil splicing device. Background Technology

[0002] As a core raw material for aluminum electrolytic capacitors, electrolytic foil plays a crucial role in the entire capacitor industry. Through meticulous electrochemical treatment, a nanoscale dielectric oxide film (Al2O3) can be formed on its surface. This oxide film possesses unique electrical properties, and its uniformity and density directly affect many key performance indicators of aluminum electrolytic capacitors.

[0003] In the actual production process of aluminum foil, to meet the needs of large-scale and efficient production, a roll-to-roll continuous production process is usually adopted. This advanced process enables continuous electrochemical treatment of aluminum foil in roll form, greatly improving production efficiency and reducing production costs. However, the length of a single roll of aluminum foil is limited, generally not exceeding 3000m. After one roll of aluminum foil is processed, in order to maintain the continuous operation of the production line and avoid production interruptions and efficiency reductions due to downtime for roll changes, it is necessary to connect the two rolls of aluminum foil through a foil splicing process to ensure smooth production.

[0004] Currently, the crucial foil splicing process relies heavily on manual operation by experienced operators. Specifically, operators must first precisely overlap the head of the next roll of foil with the tail of the previous roll, then manually tap the overlap area with a hammer to create several hammer marks. The arrangement and number of hammer marks in each row depend entirely on the operator's accumulated experience. Relying solely on rough visual judgment and operation leads to variations in operator technique and experience. When some operators produce non-standard hammer marks, the overlap area easily breaks as the foil passes through the forming equipment, causing the previous and subsequent rolls of aluminum to separate and disrupting continuous production. Utility Model Content

[0005] In view of this, the present invention provides a foil forming operation table and foil forming device to solve the above-mentioned technical problems caused by the non-standard arrangement and number of hammer marks made by operators in the prior art.

[0006] To achieve the above objectives, this application adopts the following approach:

[0007] A foil splicing workbench is provided for splicing the tail end of a previous roll of foil to the head end of a subsequent roll of foil. The workbench is located between a foil take-up roller and a foil unwinding roller on a foil splicing device. The take-up roller takes up the previous roll of foil, and the unwinding roller conveys the subsequent roll. The workbench includes a placement platform and a hammer marking assembly. The placement platform is positioned between the take-up and unwinding rollers, and the hammer marking assembly is located above the placement platform. It generates hammer marks and projects them onto the splicing area. A hammering operator then taps the area according to the hammer marks. The hammering is used to overlap the tail of the previous roll of foil with the head of the next roll of foil. The hammering marking assembly includes an adjusting screw, an adjusting bracket, and a hammering projection light plate. The adjusting screw is mounted on the placement platform and rotatably connected to the platform. One end of the adjusting bracket is mounted on the thread of the adjusting screw, and the hammering projection light plate is mounted on the other end of the adjusting bracket. The lower surface of the hammering projection light plate has several hollow hammer marks arranged in a predetermined pattern. A light emitter is installed inside the hammering projection light plate. When the light emitter is activated, the light passes through the hollow hammer marks and projects several hammer marks onto the overlapping area on the placement platform.

[0008] Preferably, the lower surface of the hammer-print projection light panel is provided with four rows of hollow hammer prints. The curvature of the first row of hollow hammer prints, which consists of the first hollow hammer prints, is consistent with the curvature of the front end of the roll head. Below the first row of hollow hammer prints, a second number of hollow hammer prints are provided at a offset from the first row to form a second row of hollow hammer prints. The second number is less than the first number, and the curvature of the second row of hollow hammer prints is less than that of the first row. Below the second row of hollow hammer prints, a second number of hollow hammer prints are provided at a offset from the second row to form a third row of hollow hammer prints. The curvature of the third row of hollow hammer prints is less than that of the second row. Below the third row of hollow hammer prints, a third number of hollow hammer prints are provided at a offset from the third row to form a fourth row of hollow hammer prints. The fourth row of hollow hammer prints is arranged in a straight line.

[0009] Preferably, the first row of hollow hammer marks is 4-5mm away from the front edge of the lower surface of the hammer mark projection light panel.

[0010] Preferably, the lower surface of the hammer-printed projection light board has a hollow scale on any side. When the light emitter is activated, the light passes through the hollow scale and projects the scale marks onto the overlapping area on the placement platform.

[0011] Preferably, the placement platform is further provided with an alignment component. The alignment component is disposed on both sides of the placement platform and is used to align the overlapping area formed by the overlapping of the tail end of the previous roll into foil and the head end of the next roll into foil. The alignment component includes a double reverse threaded screw, a pair of threaded clamping blocks and a handwheel. The double reverse threaded screw is rotatably disposed on both sides of the placement platform. The pair of threaded clamping blocks are disposed on the threads at both ends of the double reverse threaded screw. The handwheel is disposed at one end of the double reverse threaded screw and is used to rotate the double reverse threaded screw to move the pair of threaded clamping blocks toward each other or away from each other. When moving toward each other, it is used to align the overlapping area.

[0012] Preferably, the placement platform is further provided with a leveling component. The leveling component is located at any end of the placement platform and at a preset height from the placement platform. It can move along one end of the placement platform to the other end to smooth the overlapping area. The leveling component includes a pair of fixed rods, a sliding connecting rod, a leveling roller, and a handle. The pair of fixed rods are respectively disposed on both sides of the placement platform and at a predetermined distance from the placement platform. One end of the sliding connecting rod is slidably disposed on one of the fixed rods, and the other end of the sliding connecting rod is slidably disposed on the other fixed rod. The leveling roller is rotatably disposed on the sliding connecting rod. The handle is disposed on either end of the sliding connecting rod. When the sliding connecting rod is pushed along one end of the placement platform to the other end, the leveling roller rotates to smooth the overlapping area.

[0013] Preferably, the placement platform is further provided with a cutting component. The cutting component is located on the placement platform and close to one end of the foil unwinding roller. The cutting component has a preset shape to assist the operator in cutting the head of the next roll of foil into a specified shape. The cutting component includes an arc-shaped pressure plate and a height adjustment component. The arc-shaped pressure plate has an arc-shaped edge. The height adjustment component passes through the arc-shaped pressure plate and fixes it to the placement platform, and is used to adjust the height of the arc-shaped pressure plate on the placement platform.

[0014] Preferably, the placement platform is further provided with a heating component, which is disposed inside the placement platform and is used to heat the overlapping area.

[0015] Preferably, the placement platform is further provided with a blowing mechanism for blowing away impurities on the placement platform.

[0016] A foil splicing device includes a foil take-up roller and a foil unwinding roller. The take-up roller is used to take up a previous roll of foil, and the unwinding roller is used to convey a subsequent roll of foil. It also includes a foil splicing operating table for overlapping the tail end of the previous roll of foil and the head end of the subsequent roll. The operating table is located between the take-up roller and the unwinding roller. The operating table includes a placement platform and a hammer marking assembly. The placement platform is positioned between the take-up roller and the unwinding roller, and the hammer marking assembly is located above the placement platform to generate hammer marks and project them onto the overlapping area. A hammering operator then marks the foil according to the desired pattern. The hammer marks on the overlapping area are struck to complete the overlap between the tail of the previous roll of foil and the head of the next roll of foil. The hammer mark assembly includes an adjusting screw, an adjusting bracket, and a hammer mark projection light plate. The adjusting screw is disposed on the placement platform and is rotatably connected to the placement platform. One end of the adjusting bracket is disposed on the thread of the adjusting screw, and the hammer mark projection light plate is disposed on the other end of the adjusting bracket. Several hollow hammer marks are disposed on the lower surface of the hammer mark projection light plate in a predetermined arrangement. A light emitter is disposed inside the hammer mark projection light plate. When the light emitter is activated, the light passes through the hollow hammer marks and projects several hammer marks onto the overlapping area on the placement platform.

[0017] In the aforementioned foil splicing operating table and device, the perforated hammer marks on the lower surface of the hammer marking projection light board are arranged in a predetermined pattern. After the light passes through these perforated hammer marks, clear and accurate hammer mark markings are projected onto the overlapping area. These markings provide clear indications of the hammering position for the operator, ensuring precise hammering operations and contributing to improved foil splicing quality and stability. Compared to the traditional method of manually marking hammer marks on the foil, this hammer marking component utilizes light projection to complete the marking work more quickly and conveniently. Operators only need to adjust the light board position and turn on the light emitter, greatly simplifying the operation process and improving work efficiency. Furthermore, due to the accuracy and consistency of the hammer markings, the splicing position and hammering force of each roll of foil can be well controlled, ensuring product quality stability and enabling the production of more consistent products during mass production.

Detailed Implementation

[0024] To facilitate understanding of this application, a more comprehensive description will be provided below with reference to the accompanying drawings. Preferred embodiments of this application are also given. However, this application can be implemented in many different forms and is not limited to the embodiments described herein. Rather, these embodiments are provided to enable a more thorough and complete understanding of the disclosure of this application.

[0025] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs. The terminology used herein in the specification of this application is for the purpose of describing particular embodiments only and is not intended to be limiting of the application. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0026] Please refer to Figures 1 to 5In one specific embodiment, a foil splicing operating table is used to overlap the tail end of a previous roll of foil with the head end of a subsequent roll of foil. The foil splicing operating table is located between the foil take-up roller and the foil unwinding roller 100 on the foil splicing device. The foil take-up roller is used to take up the previous roll of foil, and the foil unwinding roller 100 is used to transport the subsequent roll of foil. The foil splicing operating table includes a placement platform 200 and a hammer marking assembly 600. The placement platform 200 is disposed between the foil take-up roller and the foil unwinding roller 100. The hammer marking assembly 600 is located above the placement platform 200 and is used to generate hammer marks and project them onto the overlap area. A hammering operator taps the overlap area according to the hammer marks. The overlap of the tail end of the previous roll of foil and the head end of the next roll of foil is completed. The hammer marking assembly 600 includes an adjusting screw 610, an adjusting bracket 620, and a hammer marking projection light plate 630. The adjusting screw 610 is disposed on the placement platform 200 and rotatably connected to the placement platform 200. One end of the adjusting bracket 620 is disposed on the thread of the adjusting screw 610. The hammer marking projection light plate 630 is disposed on the other end of the adjusting bracket 620. Several hollow hammer marks are disposed on the lower plate surface of the hammer marking projection light plate 630 in a predetermined arrangement. A light emitter is disposed inside the hammer marking projection light plate 630. When the light emitter is activated, the light passes through the hollow hammer marks and projects several hammer marking marks onto the overlap area on the placement platform 200.

[0027] In this embodiment, the foil splicing operating table is used as follows: First, the operator places the foil splicing operating table between the foil take-up roller and foil unwinding roller 100 on the foil splicing device. At this time, the previous roll of foil is on the take-up roller, and the next roll of foil is on the unwinding roller, waiting to be conveyed. Then, the tail end of the previous roll of foil is laid flat on the placement table 200, and the head end of the next roll of foil is overlapped with the tail end of the previous roll of foil to form an overlap area. Then, the hammer marking component 600 above the placement table 200 generates hammer marks and projects them onto the overlap area to provide a standard hammer mark position. The hammering operator taps according to the hammer marks on the overlap area to complete the overlap of the tail end of the previous roll of foil and the head end of the next roll of foil. The specific operation process is as follows:

[0028] It should be noted that before use, the adjusting screw 610 is securely mounted on the placement platform 200 and can rotate. One end of the adjusting bracket 620 is installed on the thread of the adjusting screw 610, and the hammer-print projection light panel 630 is fixed to the other end of the adjusting bracket 620. The light emitter inside the hammer-print projection light panel 630 is in the off state. First, based on the specific position of the overlapping area on the placement platform 200, adjust the hammer-print projection light panel 630 to a suitable position, ensuring it is directly above the overlapping area so that the hammer-print projection accurately covers the overlapping area. After the hammer-print projection light panel 630 is properly positioned, the operator turns on the light emitter inside the hammer-print projection light panel 630. The light emitter emits light that passes through several hollowed-out hammer marks arranged in a predetermined pattern on the lower surface of the hammer-printing projection light panel 630, projecting several hammer mark marks onto the overlapping area on the placement platform 200. The hammering operator uses a suitable tool (such as a swivel hammer) to strike the overlapping area according to the projected hammer mark marks, firmly overlapping the tail of the previous roll of foil with the head of the next roll. After the hammering operation is completed, the operator turns off the light emitter, completing one hammering and marking operation. It should be noted that the hollowed-out hammer marks on the hammer-printing projection light panel 630 in this embodiment are specially arranged. This arrangement results in greater tension on the overlapping foil, making it less prone to tearing. See the attached diagram for the specific arrangement.

[0029] The perforated hammer marks on the lower surface of the hammer-marking projection light panel 630 are arranged in a predetermined pattern. Light passing through these perforated marks projects clear and accurate hammer marks onto the overlapping area. These marks provide clear indications of the hammering position for the operator, ensuring precise hammering and improving the quality and stability of foil splicing. Compared to the traditional method of manually marking hammer positions on the formed foil, this hammer-marking component 600 utilizes light projection to complete the marking work more quickly and conveniently. Operators only need to adjust the light panel position and turn on the light emitter, greatly simplifying the operation process and improving work efficiency. Furthermore, due to the accuracy and consistency of the hammer marks, the splicing position and hammering force of each roll of formed foil can be well controlled, ensuring product quality stability and enabling the production of more consistent products during mass production.

[0030] Furthermore, the lower surface of the hammer-print projection light panel 630 is provided with four rows of hollow hammer prints. The curvature of the first row of hollow hammer prints, which consists of the first hollow hammer prints, is consistent with the curvature of the front end of the roll head. Below the first row of hollow hammer prints, a second number of hollow hammer prints are offset from the first row to form a second row of hollow hammer prints. The second number is less than the first number, and the curvature of the second row of hollow hammer prints is less than that of the first row. Below the second row of hollow hammer prints, a second number of hollow hammer prints are offset from the second row to form a third row of hollow hammer prints. The curvature of the third row of hollow hammer prints is less than that of the second row. Below the third row of hollow hammer prints, a third number of hollow hammer prints are offset from the third row to form a fourth row of hollow hammer prints. The fourth row of hollow hammer prints is arranged in a straight line.

[0031] For example, the radius of the arc at the front end of the next roll of foil is 10cm. The first row of hollow hammer marks consists of 15 hollow hammer marks, with their arc matching the front end of the roll, forming an arc with a radius of approximately 10cm. The second row of hollow hammer marks consists of 14 hollow hammer marks, staggered from the first row, forming an arc with a radius of approximately 8cm. The third row of hollow hammer marks also consists of 14 hollow hammer marks, staggered from the second row, forming an arc with a radius of approximately 6cm. The fourth row of hollow hammer marks consists of 12 hollow hammer marks, arranged in a straight line below the third row. The hammer mark projection light panel 630 can be rectangular, and the hollow hammer marks on the lower panel can be made using laser cutting technology to ensure the accurate shape and position of each hollow hammer mark. The light emitter can use high-brightness LED light groups, which can provide sufficient and uniform light, making the hammer mark markings clearly visible.

[0032] The hammering personnel, based on the hammer marking patterns projected on the overlapping area, use appropriate tools (such as a swivel hammer) to hammer in sequence from the first row to the fourth row. First, they hammer along the first row of hollow hammer markings that align with the arc of the front end of the roll, then they hammer the second and third rows of hollow hammer markings that are arranged in a staggered manner, and finally they hammer the fourth row of hollow hammer markings that are arranged in a straight line, firmly overlapping the two rolls of foil together.

[0033] Thus, a first number (e.g., 15) of hammer marks are struck along the curved edge of the roll head, forming the first row of hammer marks that matches the curvature of the roll head's front end. This primarily provides the initial foundation for connecting subsequent rows of hammer marks, while also initially fixing the relative positions of the roll head and tail. Furthermore, the distribution of hammer marks along the curved edge adapts to the shape of the roll head, allowing stress to begin dispersing in the curved area. Below the first row of hammer marks, a second row of hammer marks is struck, offset from the first row, with a smaller number (e.g., 14) and a smaller curvature. Because the curvature of the second row of hammer marks is smaller than that of the first row, 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 second number (e.g., 14) of hammer marks, also with a smaller curvature, is struck, offset from the second row of hammer marks. The hammer marks further increase the connection points and connection area, improving the roll head's resistance to external forces and reducing the possibility of loosening or separation caused by external forces. Through smaller arcs and staggered arrangements, the stress transmission path is further refined, allowing stress to be distributed more evenly throughout the roll head. Below the third row of hammer marks, a third number (e.g., 12) of fourth row hammer marks are struck, staggered from the third row. These fourth row hammer marks are arranged in a straight line, allowing for localized stress adjustment in the area near the right-angled edge of the roll tail. Combined with the upper rows of arc-shaped hammer marks, this forms a three-dimensional stress dispersion network. When the roll head is subjected to external forces, stress can be transmitted and dispersed throughout the roll head via this network of arc-shaped and straight hammer marks, effectively reducing the possibility of stress concentration and deformation.

[0034] Operators can quickly and accurately perform the tapping operation based on the hammer marks, eliminating the need to spend a lot of time determining the tapping position. This shortens the foil splicing operation time and improves the overall production efficiency of foil splicing. The clear and distinct hammer mark layout makes the hammering operation more standardized and regulated, reducing the fluctuation in foil splicing quality caused by 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 is consistent with the arc shape, stress can be evenly transmitted along the arc when subjected to external force, avoiding stress concentration at the edge of the arc. The smaller curvature and fewer connection points of the second row of hammer marks allow for more even stress distribution during expansion and contraction, reducing the possibility of breakage due to local stress concentration. The curvature of the third row of hammer marks is further reduced, which can further refine the stress transmission path, allowing the stress to be more evenly distributed throughout the roll head. The fourth row of hammer marks is arranged in a straight line, which can adjust local stress in the area near the right angle edge of the roll tail, making the stress distribution of the entire overlap area more balanced and less prone to tearing.

[0035] Furthermore, the first row of hollowed-out hammer marks is 4-5mm away from the front edge of the lower surface of the hammer-marked projection light panel 630. If the distance is too close, the metal at the curved edge may be excessively deformed during hammering, resulting in reduced edge strength. This could lead to cracking of the curved edge during subsequent formation processing. Conversely, if the distance is too far, the stress-dispersing effect of the curved front edge cannot be fully utilized, potentially causing stress concentration in other areas of the overlap region, which would also reduce the reliability of the connection.

[0036] Furthermore, the lower surface of the hammer-printed projection light panel 630 is provided with a hollow scale on any side. When the light emitter is activated, the light passes through the hollow scale and projects the scale marks onto the overlapping area on the placement platform 200.

[0037] Furthermore, the placement platform 200 is also provided with an alignment component 300. The alignment component 300 is disposed on both sides of the placement platform 200 and is used to align the overlapping area formed by the overlapping of the tail end of the previous roll into foil and the head end of the next roll into foil. The alignment component 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 is rotatably disposed on both sides of the placement platform 200. The pair of threaded clamping blocks are respectively disposed on the threads at both ends of the double reverse threaded screw 310. The handwheel 330 is disposed 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 towards each other or away from each other. When moving towards each other, it is used to align the overlapping area.

[0038] When it is necessary to align the two sides of the overlap area formed by the overlap of the tail end of the previous roll of foil and the head end of the next roll of foil, the operator first goes to the placement table 200 of the foil forming and receiving workbench and locates the handwheel 330 on the double reverse threaded screw 310 on the side of the placement table 200. The operator holds the handwheel 330 and rotates it clockwise or counterclockwise according to the actual situation of the overlap area. Since 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 threaded clamping blocks 320 respectively set on the threads at both ends of the double reverse threaded screw 310 to move towards each other. That is, one threaded clamping block moves along the screw towards the other threaded clamping block, and the other moves in the same way. As a pair of threaded clamping blocks 320 move toward each other, they gradually approach the overlapping area and clamp and push the forming foil on both sides of the overlapping area, ensuring accurate alignment of the two sides of the overlapping area. Once the ideal alignment is achieved, stop rotating the handwheel 330. If it is necessary to loosen the alignment, rotate the handwheel 330 in the opposite direction, causing the pair of threaded clamping blocks 320 to move away from each other and disengage from the overlapping area.

[0039] The main function of the alignment component 300 is to ensure that the two sides of the overlapping area are accurately aligned. If the overlapping area is not aligned, it may cause the overlapping area to tear easily in subsequent processes.

[0040] Furthermore, a leveling component 400 is also provided on the placement platform 200. The leveling component 400 is located at any end of the placement platform 200 and at a preset height from the placement platform 200. It can move along one end of the placement platform 200 to the other end to smooth the overlapping area. The leveling component 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 provided on both sides of the placement platform 200. The sliding connecting rod 420 is slidably mounted on one of the fixed rods at a predetermined distance from the placement platform 200. The other end of the sliding connecting rod 420 is slidably mounted on another fixed rod. The leveling roller 430 is rotatably mounted on the sliding connecting rod 420. The handle 440 is mounted on either end of the sliding connecting rod 420. When the sliding connecting rod 420 is pushed from one end of the placement platform 200 to the other end, the leveling roller 430 rotates to smooth the overlapping area.

[0041] In use, the operator holds handle 440 and smoothly pushes the sliding connecting rod 420 from one end of the placement platform 200 to the other along its length (the leveling component 400 is in its initial position before operation). During the pushing process, 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, the leveling roller 430 will roll as the sliding connecting rod 420 moves. When the operator pushes the sliding connecting rod 420 to the other end of the placement platform 200, the leveling roller 430 has completed the rolling and smoothing operation of the entire overlapping area. At this point, the handle 440 is released, completing one leveling process. If the leveling effect is not satisfactory, the above pushing operation can be repeated until the overlapping area achieves a satisfactory level of flatness. It is important to note that during use, the leveling roller 430 should fit tightly against the overlapping area.

[0042] During the overlapping process, wrinkles and unevenness may occur between the two rolls of chemically formed foil. The rolling of the leveling roller 430 can apply a certain pressure to ensure that the chemically formed foil in the overlapping area is fully adhered, eliminating wrinkles and unevenness and ensuring the quality of the overlap.

[0043] Using this leveling component 400 can effectively improve the flatness of the overlapping area, resulting in a higher quality oxide film formed subsequently, thereby improving the overall quality of aluminum electrolytic capacitors produced based on these formed foils.

[0044] Furthermore, a cutting component 500 is also provided on the placement table 200. The cutting component 500 is located on the placement table 200 and close to one end of the 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 foil into a specified shape. The cutting component 500 includes an arc-shaped pressure plate 510 and a height adjustment component 520. The arc-shaped pressure plate 510 has an arc-shaped edge. The height adjustment component 520 passes through the arc-shaped pressure plate 510 and fixes it to the placement table 200, and is used to adjust the height of the arc-shaped pressure plate 510 on the placement table 200.

[0045] The operator adjusts the height of the arc-shaped pressure plate 510 on the placement table 200 by operating the height adjustment component 520 (the height adjustment component 520 can be a bolt and nut structure, with the bolt passing vertically through the arc-shaped pressure plate 510 and fixed in a pre-set threaded hole in the placement table 200; rotating the nut changes the distance between the arc-shaped pressure plate 510 and the placement table 200). Adjusting the arc-shaped pressure plate 510 to a suitable height ensures that when the next roll of formed foil is placed on the placement table 200 for cutting, the arc-shaped edge of the pressure plate 510 accurately presses onto the formed foil, forming the desired cutting contour. Because the arc-shaped pressure plate 510 provides a clear arc contour, the operator can easily tear off excess formed foil along the arc-shaped edge of the pressure plate 510.

[0046] Using the cutting component 500 can significantly improve the cutting accuracy of the head of the next roll of foil. Because the cutting operation becomes simpler and faster, operators can complete the cutting steps more quickly, reducing wasted time during the cutting process and improving work efficiency.

[0047] Furthermore, a heating component is also provided on the placement platform 200. The heating component is located inside the placement platform 200 and is used to heat the overlapping area.

[0048] In this embodiment, the heating component can be an electric heating wire, which can be placed inside the placement platform 200. The control switch for starting the electric heating wire is located outside the placement platform 200 so that the operator can start or stop it.

[0049] Furthermore, the placement platform 200 is also provided with a blower mechanism for blowing away impurities on the placement platform 200.

[0050] During the foil bonding process, impurities such as dust, metal shavings, and fibers may be present on the placement stage 200. If these impurities adhere to the overlapping area of ​​the foil, they will cause uneven oxide film growth and localized weak points during subsequent electrochemical treatment to form the oxide film. The impurity blowing mechanism can effectively remove impurities from the placement stage 200, ensuring a clean overlapping area and thus forming a uniform oxide film.

[0051] This application also provides a foil splicing device, including a foil take-up roller and a foil unwinding roller 100. The foil take-up roller is used to take up the previous roll of foil, and the foil unwinding roller 100 is used to transport the next roll of foil. It also includes a foil splicing operating table for overlapping the tail end of the previous roll of foil and the head end of the next roll of foil. The foil splicing operating table is located between the foil take-up roller and the foil unwinding roller 100 on the foil splicing device. The foil splicing operating table includes a placement platform 200 and a hammer marking component 600. The placement platform 200 is disposed between the foil take-up roller and the foil unwinding roller 100, and the hammer marking component 600 is located above the placement platform 200 for generating hammer marks and projecting them onto the overlapping area. The hammering operator marks the overlapping area... The hammer marks on the foil are struck to overlap the tail of the previous roll and the head of the next roll. The hammer mark assembly 600 includes an adjusting screw 610, an adjusting bracket 620, and a hammer mark projection light plate 630. The adjusting screw 610 is mounted on the placement platform 200 and rotatably connected to it. One end of the adjusting bracket 620 is threaded onto the adjusting screw 610. The hammer mark projection light plate 630 is mounted on the other end of the adjusting bracket 620. The lower surface of the hammer mark projection light plate 630 has several hollow hammer marks arranged in a predetermined pattern. A light emitter is installed inside the hammer mark projection light plate 630. When the light emitter is activated, light passes through the hollow hammer marks and projects several hammer marks onto the overlapping area on the placement platform 200.

[0052] In use, the operating table of the electrolytic foil splicing device provided in this application is first placed between the electrolytic foil take-up roller and the electrolytic foil unwinding roller 100 on the electrolytic foil splicing device by the operator. At this time, the previous roll of electrolytic foil is on the take-up roller, and the next roll of electrolytic foil is on the unwinding roller waiting to be conveyed. Then, the tail end of the previous roll of electrolytic foil is laid flat on the placement table 200, and the head end of the next roll of electrolytic foil is overlapped on the tail end of the previous roll of electrolytic foil to form an overlap area. Then, the hammer marking component 600 above the placement table 200 generates hammer marks and projects them onto the overlap area to provide a standard hammer mark position. The hammering operator taps according to the hammer marks on the overlap area to complete the overlap of the tail end of the previous roll of electrolytic foil and the head end of the next roll of electrolytic foil. The specific operation process is as follows:

[0053] It should be noted that before use, the adjusting screw 610 is securely mounted on the placement platform 200 and can rotate. One end of the adjusting bracket 620 is installed on the thread of the adjusting screw 610, and the hammer-print projection light panel 630 is fixed to the other end of the adjusting bracket 620. The light emitter inside the hammer-print projection light panel 630 is in the off state. First, based on the specific position of the overlapping area on the placement platform 200, adjust the hammer-print projection light panel 630 to a suitable position, ensuring it is directly above the overlapping area so that the hammer-print projection accurately covers the overlapping area. After the hammer-print projection light panel 630 is properly positioned, the operator turns on the light emitter inside the hammer-print projection light panel 630. The light emitter emits light that passes through several hollowed-out hammer marks arranged in a predetermined pattern on the lower surface of the hammer-printing projection light panel 630, projecting several hammer mark marks onto the overlapping area on the placement platform 200. The hammering operator uses a suitable tool (such as a swivel hammer) to strike the overlapping area according to the projected hammer mark marks, firmly overlapping the tail of the previous roll of foil with the head of the next roll. After the hammering operation is completed, the operator turns off the light emitter, completing one hammering and marking operation. It should be noted that the hollowed-out hammer marks on the hammer-printing projection light panel 630 in this embodiment are specially arranged. This arrangement results in greater tension on the overlapping foil, making it less prone to tearing. See the attached diagram for the specific arrangement.

[0054] The perforated hammer marks on the lower surface of the hammer-marking projection light panel 630 are arranged in a predetermined pattern. Light passing through these perforated marks projects clear and accurate hammer marks onto the overlapping area. These marks provide clear indications of the hammering position for the operator, ensuring precise hammering and improving the quality and stability of foil splicing. Compared to the traditional method of manually marking hammer positions on the formed foil, this hammer-marking component 600 utilizes light projection to complete the marking work more quickly and conveniently. Operators only need to adjust the light panel position and turn on the light emitter, greatly simplifying the operation process and improving work efficiency. Furthermore, due to the accuracy and consistency of the hammer marks, the splicing position and hammering force of each roll of formed foil can be well controlled, ensuring product quality stability and enabling the production of more consistent products during mass production.

[0055] Furthermore, the lower surface of the hammer-print projection light panel 630 is provided with four rows of hollow hammer prints. The curvature of the first row of hollow hammer prints, which consists of the first hollow hammer prints, is consistent with the curvature of the front end of the roll head. Below the first row of hollow hammer prints, a second number of hollow hammer prints are offset from the first row to form a second row of hollow hammer prints. The second number is less than the first number, and the curvature of the second row of hollow hammer prints is less than that of the first row. Below the second row of hollow hammer prints, a second number of hollow hammer prints are offset from the second row to form a third row of hollow hammer prints. The curvature of the third row of hollow hammer prints is less than that of the second row. Below the third row of hollow hammer prints, a third number of hollow hammer prints are offset from the third row to form a fourth row of hollow hammer prints. The fourth row of hollow hammer prints is arranged in a straight line.

[0056] For example, the radius of the arc at the front end of the next roll of foil is 10cm. The first row of hollow hammer marks consists of 15 hollow hammer marks, with their arc matching the front end of the roll, forming an arc with a radius of approximately 10cm. The second row of hollow hammer marks consists of 14 hollow hammer marks, staggered from the first row, forming an arc with a radius of approximately 8cm. The third row of hollow hammer marks also consists of 14 hollow hammer marks, staggered from the second row, forming an arc with a radius of approximately 6cm. The fourth row of hollow hammer marks consists of 12 hollow hammer marks, arranged in a straight line below the third row. The hammer mark projection light panel 630 can be rectangular, and the hollow hammer marks on the lower panel can be made using laser cutting technology to ensure the accurate shape and position of each hollow hammer mark. The light emitter can use high-brightness LED light groups, which can provide sufficient and uniform light, making the hammer mark markings clearly visible.

[0057] The hammering personnel, based on the hammer marking patterns projected on the overlapping area, use appropriate tools (such as a swivel hammer) to hammer in sequence from the first row to the fourth row. First, they hammer along the first row of hollow hammer markings that align with the arc of the front end of the roll, then they hammer the second and third rows of hollow hammer markings that are arranged in a staggered manner, and finally they hammer the fourth row of hollow hammer markings that are arranged in a straight line, firmly overlapping the two rolls of foil together.

[0058] Thus, a first number (e.g., 15) of hammer marks are struck along the curved edge of the roll head, forming the first row of hammer marks that matches the curvature of the roll head's front end. This primarily provides the initial foundation for connecting subsequent rows of hammer marks, while also initially fixing the relative positions of the roll head and tail. Furthermore, the distribution of hammer marks along the curved edge adapts to the shape of the roll head, allowing stress to begin dispersing in the curved area. Below the first row of hammer marks, a second row of hammer marks is struck, offset from the first row, with a smaller number (e.g., 14) and a smaller curvature. Because the curvature of the second row of hammer marks is smaller than that of the first row, 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 second number (e.g., 14) of hammer marks, also with a smaller curvature, is struck, offset from the second row of hammer marks. The hammer marks further increase the connection points and connection area, improving the roll head's resistance to external forces and reducing the possibility of loosening or separation caused by external forces. Through smaller arcs and staggered arrangements, the stress transmission path is further refined, allowing stress to be distributed more evenly throughout the roll head. Below the third row of hammer marks, a third number (e.g., 12) of fourth row hammer marks are struck, staggered from the third row. These fourth row hammer marks are arranged in a straight line, allowing for localized stress adjustment in the area near the right-angled edge of the roll tail. Combined with the upper rows of arc-shaped hammer marks, this forms a three-dimensional stress dispersion network. When the roll head is subjected to external forces, stress can be transmitted and dispersed throughout the roll head via this network of arc-shaped and straight hammer marks, effectively reducing the possibility of stress concentration and deformation.

[0059] Operators can quickly and accurately perform the tapping operation based on the hammer marks, eliminating the need to spend a lot of time determining the tapping position. This shortens the foil splicing operation time and improves the overall production efficiency of foil splicing. The clear and distinct hammer mark layout makes the hammering operation more standardized and regulated, reducing the fluctuation in foil splicing quality caused by 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 is consistent with the arc shape, stress can be evenly transmitted along the arc when subjected to external force, avoiding stress concentration at the edge of the arc. The smaller curvature and fewer connection points of the second row of hammer marks allow for more even stress distribution during expansion and contraction, reducing the possibility of breakage due to local stress concentration. The curvature of the third row of hammer marks is further reduced, which can further refine the stress transmission path, allowing the stress to be more evenly distributed throughout the roll head. The fourth row of hammer marks is arranged in a straight line, which can adjust local stress in the area near the right angle edge of the roll tail, making the stress distribution of the entire overlap area more balanced and less prone to tearing.

[0060] Furthermore, the first row of hollowed-out hammer marks is 4-5mm away from the front edge of the lower surface of the hammer-marked projection light panel 630. If the distance is too close, the metal at the curved edge may be excessively deformed during hammering, resulting in reduced edge strength. This could lead to cracking of the curved edge during subsequent formation processing. Conversely, if the distance is too far, the stress-dispersing effect of the curved front edge cannot be fully utilized, potentially causing stress concentration in other areas of the overlap region, which would also reduce the reliability of the connection.

[0061] Furthermore, the lower surface of the hammer-printed projection light panel 630 is provided with a hollow scale on any side. When the light emitter is activated, the light passes through the hollow scale and projects the scale marks onto the overlapping area on the placement platform 200.

[0062] Furthermore, the placement platform 200 is also provided with an alignment component 300. The alignment component 300 is disposed on both sides of the placement platform 200 and is used to align the overlapping area formed by the overlapping of the tail end of the previous roll into foil and the head end of the next roll into foil. The alignment component 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 is rotatably disposed on both sides of the placement platform 200. The pair of threaded clamping blocks are respectively disposed on the threads at both ends of the double reverse threaded screw 310. The handwheel 330 is disposed 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 towards each other or away from each other. When moving towards each other, it is used to align the overlapping area.

[0063] When it is necessary to align the two sides of the overlap area formed by the overlap of the tail end of the previous roll of foil and the head end of the next roll of foil, the operator first goes to the placement table 200 of the foil forming and receiving workbench and locates the handwheel 330 on the double reverse threaded screw 310 on the side of the placement table 200. The operator holds the handwheel 330 and rotates it clockwise or counterclockwise according to the actual situation of the overlap area. Since 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 threaded clamping blocks 320 respectively set on the threads at both ends of the double reverse threaded screw 310 to move towards each other. That is, one threaded clamping block moves along the screw towards the other threaded clamping block, and the other moves in the same way. As a pair of threaded clamping blocks 320 move toward each other, they gradually approach the overlapping area and clamp and push the forming foil on both sides of the overlapping area, ensuring accurate alignment of the two sides of the overlapping area. Once the ideal alignment is achieved, stop rotating the handwheel 330. If it is necessary to loosen the alignment, rotate the handwheel 330 in the opposite direction, causing the pair of threaded clamping blocks 320 to move away from each other and disengage from the overlapping area.

[0064] The main function of the alignment component 300 is to ensure that the two sides of the overlapping area are accurately aligned. If the overlapping area is not aligned, it may cause the overlapping area to tear easily in subsequent processes.

[0065] Furthermore, a leveling component 400 is also provided on the placement platform 200. The leveling component 400 is located at any end of the placement platform 200 and at a preset height from the placement platform 200. It can move along one end of the placement platform 200 to the other end to smooth the overlapping area. The leveling component 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 provided on both sides of the placement platform 200. The sliding connecting rod 420 is slidably mounted on one of the fixed rods at a predetermined distance from the placement platform 200. The other end of the sliding connecting rod 420 is slidably mounted on another fixed rod. The leveling roller 430 is rotatably mounted on the sliding connecting rod 420. The handle 440 is mounted on either end of the sliding connecting rod 420. When the sliding connecting rod 420 is pushed from one end of the placement platform 200 to the other end, the leveling roller 430 rotates to smooth the overlapping area.

[0066] In use, the operator holds handle 440 and smoothly pushes the sliding connecting rod 420 from one end of the placement platform 200 to the other along its length (the leveling component 400 is in its initial position before operation). During the pushing process, 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, the leveling roller 430 will roll as the sliding connecting rod 420 moves. When the operator pushes the sliding connecting rod 420 to the other end of the placement platform 200, the leveling roller 430 has completed the rolling and smoothing operation of the entire overlapping area. At this point, the handle 440 is released, completing one leveling process. If the leveling effect is not satisfactory, the above pushing operation can be repeated until the overlapping area achieves a satisfactory level of flatness. It is important to note that during use, the leveling roller 430 should fit tightly against the overlapping area.

[0067] During the overlapping process, wrinkles and unevenness may occur between the two rolls of chemically formed foil. The rolling of the leveling roller 430 can apply a certain pressure to ensure that the chemically formed foil in the overlapping area is fully adhered, eliminating wrinkles and unevenness and ensuring the quality of the overlap.

[0068] Using this leveling component 400 can effectively improve the flatness of the overlapping area, resulting in a higher quality oxide film formed subsequently, thereby improving the overall quality of aluminum electrolytic capacitors produced based on these formed foils.

[0069] Furthermore, a cutting component 500 is also provided on the placement table 200. The cutting component 500 is located on the placement table 200 and close to one end of the 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 foil into a specified shape. The cutting component 500 includes an arc-shaped pressure plate 510 and a height adjustment component 520. The arc-shaped pressure plate 510 has an arc-shaped edge. The height adjustment component 520 passes through the arc-shaped pressure plate 510 and fixes it to the placement table 200, and is used to adjust the height of the arc-shaped pressure plate 510 on the placement table 200.

[0070] The operator adjusts the height of the arc-shaped pressure plate 510 on the placement table 200 by operating the height adjustment component 520 (the height adjustment component 520 can be a bolt and nut structure, with the bolt passing vertically through the arc-shaped pressure plate 510 and fixed in a pre-set threaded hole in the placement table 200; rotating the nut changes the distance between the arc-shaped pressure plate 510 and the placement table 200). Adjusting the arc-shaped pressure plate 510 to a suitable height ensures that when the next roll of formed foil is placed on the placement table 200 for cutting, the arc-shaped edge of the pressure plate 510 accurately presses onto the formed foil, forming the desired cutting contour. Because the arc-shaped pressure plate 510 provides a clear arc contour, the operator can easily tear off excess formed foil along the arc-shaped edge of the pressure plate 510.

[0071] Using the cutting component 500 can significantly improve the cutting accuracy of the head of the next roll of foil. Because the cutting operation becomes simpler and faster, operators can complete the cutting steps more quickly, reducing wasted time during the cutting process and improving work efficiency.

[0072] Furthermore, a heating component is also provided on the placement platform 200. The heating component is located inside the placement platform 200 and is used to heat the overlapping area.

[0073] In this embodiment, the heating component can be an electric heating wire, which can be placed inside the placement platform 200. The control switch for starting the electric heating wire is located outside the placement platform 200 so that the operator can start or stop it.

[0074] Furthermore, the placement platform 200 is also provided with a blower mechanism for blowing away impurities on the placement platform 200.

[0075] During the foil bonding process, impurities such as dust, metal shavings, and fibers may be present on the placement stage 200. If these impurities adhere to the overlapping area of ​​the foil, they will cause uneven oxide film growth and localized weak points during subsequent electrochemical treatment to form the oxide film. The impurity blowing mechanism can effectively remove impurities from the placement stage 200, ensuring a clean overlapping area and thus forming a uniform oxide film.

[0076] The above description is only a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any person skilled in the art can easily conceive of various equivalent modifications or substitutions within the technical scope disclosed in this utility model, and these modifications or substitutions should all be covered within the protection scope of this utility model.
