Description

Technical Field

[0001] The invention relates to the technical field of pore-forming devices, and in particular to a corrosion pore-forming device for improving the corrosion specific volume of aluminum foil. Background Art

[0002] The existing Chinese patent with authorization announcement number CN113943939A discloses a corrosion pore-forming device and a pore-forming method for improving the corrosion specific volume of electrode foil, comprising the following steps: S1: conveying the aluminum foil to the interior of a pretreatment box, and decontaminating and degreasing the surface of the aluminum foil with the pretreatment liquid in the pretreatment box; S2: conveying the cleaned aluminum foil to the interior of a drying box, and drying the wet aluminum foil with the drying device of the drying box; S3: the aluminum foil that has passed the pretreatment will be conveyed to the interior of the corrosion pore-forming device, and the aluminum foil will be corroded and pore-formed by the corrosion liquid; S4: the micro-nano bubbles generated by the micro-nano bubble generator will be conveyed to the interior of the corrosion pore-forming device through the first exhaust device and the second exhaust device, so that the corrosion liquid generates a large number of micro-nano bubbles, the bubbles contact the surface of the aluminum foil and explode, and the explosion pressure and the corrosiveness of the corrosion liquid will cause countless perforations in the aluminum foil, thereby completing the corrosion pore-forming work on the aluminum foil.

[0003] However, the above scheme still has the following problems in practical application: first, when the aluminum foil is placed in a mixed acid solution containing sulfuric acid and hydrochloric acid for electrolytic corrosion, an aluminum sulfate film will be formed on the surface of the aluminum foil to prevent the aluminum substrate from continuing to react with the mixed acid solution. The above pore-forming method can only be carried out by the corrosion pore-forming device. During the corrosion pore-forming process, the aluminum sulfate film covering the surface of the aluminum foil cannot be cleaned. Once the surface of the aluminum foil is covered with the aluminum sulfate film, the aluminum substrate cannot continue to react with the mixed acid solution, resulting in a small number of pores on the foil surface and insufficient hole depth. In addition, since the spoiler fan can make the liquid flow downward all the time, the liquid is also flowing when replacing or injecting a new mixed acid solution. During the corrosion pore-forming process, the aluminum foil in the corrosion pore-forming device will swing up and down under the action of the liquid flow, which is very likely to cause uneven pores or pore merging, reducing the quality of the product and the specific volume of the final anode foil. Secondly, since the thickness of the aluminum foil is relatively thin, it is difficult for the end of the new aluminum foil roll to be inserted into the pretreatment box, the drying box and the corrosion pore-forming device in sequence and pass through, and the operation process is extremely difficult. Summary of the invention

[0004] The purpose of the present invention is to solve the shortcomings existing in the prior art, and to propose a corrosion pore-forming device for improving the corrosion specific volume of aluminum foil, which can remove the aluminum sulfate film attached to the surface of the aluminum foil during the corrosion pore-forming process, so that the aluminum substrate after the initial corrosion pore-forming continues to react with the mixed acid solution, has a good pore-forming effect, improves the specific volume of the anode foil, and is convenient for installing the aluminum foil on the device, making the operation simpler.

[0014] Compared with the prior art, the present invention has the following beneficial effects:

[0015] During use, the cover body is driven to rise and open by the lifting mechanism. At the same time, the first hole punching frame, the film removing frame, and the second hole punching frame all extend out of the first hole punching groove, the film removing groove, and the second hole punching groove. One section of the aluminum foil to be corroded and hole punched can be wound around the first tensioning mechanism, the film removing mechanism, and the second tensioning mechanism. After the aluminum foil is installed, the lifting mechanism drives the cover body to descend. At the same time, the first tensioning mechanism, the film removing mechanism, and the second tensioning mechanism all gradually descend into the first hole punching groove, the film removing groove, and the second hole punching groove, and the operation is simpler. The first hole punching frame drives the aluminum foil to extend into the first hole punching groove, so that the aluminum foil reacts with the mixed acid solution for primary corrosion and hole punching, and holes can appear on the foil surface. During the hole punching process, aluminum sulfate film gradually forms on the foil surface. The aluminum foil after primary corrosion and hole punching moves to the film removing frame, and the aluminum sulfate film on the foil surface is removed by the fluosilicic acid solution in the film removing groove, exposing the foil surface on the aluminum substrate and the holes initially generated, so that the foil surface can react with the mixed acid solution again. The aluminum foil after film removal moves to the second hole punching groove, and the foil surface reacts with the mixed acid solution for secondary corrosion and hole punching, so that more holes can appear on the foil surface and the holes initially generated are corroded deeper, thereby improving the uniformity and quantity of the overall hole punching of the aluminum foil, with good hole punching effect and improved specific capacitance of the electrode foil. The first tensioning mechanism and the second tensioning mechanism prevent the up and down swing of the aluminum foil caused by the liquid flow, and the hole punching is more uniform. The film removing mechanism increases the contact area between the aluminum foil and the fluosilicic acid solution, prolongs the contact time between the aluminum foil and the fluosilicic acid solution, and the aluminum sulfate film on the foil surface is removed more thoroughly. The present invention can not only remove the aluminum sulfate film attached to the surface of the aluminum foil during the corrosion and hole punching process, enable the aluminum substrate after primary corrosion and hole punching to continue to react with the mixed acid solution, with good hole punching effect and improved specific capacitance of the anode foil, but also facilitate the installation of the aluminum foil on the device, and the operation is simpler.

Detailed implementation manners

[0024] The following description is used to disclose the present invention so that those skilled in the art can implement the present invention. The preferred embodiments described below are only examples, and those skilled in the art can think of other obvious variations.

[0025] As shown in the appendix Figures 1-7A corrosion pore-forming device for improving the corrosion specific capacitance of aluminum foil, as shown, includes a tank body 1, a cover body 2 covering the tank body 1, a lifting mechanism 3 for driving the cover body 2 to rise or fall, a first pore-forming rack 21, a film-removing rack 22, and a second pore-forming rack 23 arranged in sequence from left to right at the bottom of the cover body 2. Tensioning mechanisms 4, a film-removing mechanism 5, and a second tensioning mechanism 6 are respectively arranged on the fronts of the first pore-forming rack 21, the film-removing rack 22, and the second pore-forming rack 23. A first partition board and a second partition board are vertically arranged inside the tank body 1. The first partition board and the second partition board divide the inside of the tank body 1 into a first pore-forming tank 11, a film-removing tank 12, and a second pore-forming tank 13 in sequence from left to right. The first pore-forming tank 11, the film-removing tank 12, and the second pore-forming tank 13 are used to contain mixed acid solution, fluosilicic acid solution, and mixed acid solution respectively. When the cover body 2 is in the lowered state, the first pore-forming rack 21, the film-removing rack 22, and the second pore-forming rack 23 respectively extend into the first pore-forming tank 11, the film-removing tank 12, and the second pore-forming tank 13.

[0026] During use, the lifting mechanism 3 drives the cover body 2 to rise and open. At the same time, the first pore-forming rack 21, the film-removing rack 22, and the second pore-forming rack 23 all extend out of the first pore-forming tank 11, the film-removing tank 12, and the second pore-forming tank 13. Then, one section of the aluminum foil 10 to be corroded and pore-formed can be wound around the tensioning mechanism 4, the film-removing mechanism 5, and the second tensioning mechanism 6. After the aluminum foil 10 is installed, the lifting mechanism 3 drives the cover body 2 to descend. At the same time, the tensioning mechanism 4, the film-removing mechanism 5, and the second tensioning mechanism 6 all gradually descend into the first pore-forming tank 11, the film-removing tank 12, and the second pore-forming tank 13, and the operation is simpler.

[0027] The first pore-forming rack 21 drives the aluminum foil 10 to extend into the first pore-forming tank 11, so that the aluminum foil 10 undergoes primary corrosion and pore formation with the mixed acid solution, and pores can appear on the foil surface. During the pore-forming process, an aluminum sulfate film gradually forms on the foil surface. The aluminum foil 10 that has undergone primary corrosion and pore formation moves to the film-removing rack 22, and the aluminum sulfate film on the foil surface is removed by the fluosilicic acid solution in the film-removing tank 12, exposing the foil surface on the aluminum substrate and the pores initially generated, so that the foil surface can come into contact and react with the mixed acid solution again. The aluminum foil 10 after film removal moves to the second pore-forming tank 13, and the foil surface reacts with the mixed acid solution for secondary corrosion and pore formation, so that more pores can appear on the foil surface and the pores initially generated are corroded deeper, thereby improving the uniformity and quantity of the overall pore formation of the aluminum foil, achieving a good pore-forming effect, and increasing the specific capacitance of the electrode foil.

[0028] The first tensioning mechanism 4 and the second tensioning mechanism 6 prevent the up-and-down swing of the aluminum foil 10 caused by the liquid flow, and the pore formation is more uniform. The film-removing mechanism 5 increases the contact area between the aluminum foil 10 and the fluosilicic acid solution, extends the contact time between the aluminum foil 10 and the fluosilicic acid solution, and the aluminum sulfate film on the surface of the foil 10 is removed more thoroughly.

[0029] The present invention can not only remove the aluminum sulfate film adhering to the surface of the aluminum foil 10 during the corrosion and pore-forming process, enabling the aluminum substrate after the initial corrosion and pore-forming to continue to react with the mixed acid solution, resulting in good pore-forming effect, improving the specific capacitance of the anode foil, but also facilitating the installation of the aluminum foil 10 onto the device and making the operation simpler.

[0030] There is also an effect: during the continuous forward movement of the aluminum foil 10, the initial corrosion and pore-forming, film removal, and secondary corrosion and pore-forming are carried out in sequence, eliminating the need to stop the machine for multiple pore-forming operations, thereby improving the efficiency of pore-forming.

[0031] In this embodiment, the aluminum foil moving drive device and the aluminum foil winding device used to drive the aluminum foil 10 to move on the first tensioning mechanism 4, the film removal mechanism 5, and the second tensioning mechanism 6 both belong to the prior art, so they will not be elaborated here.

[0032] As attached Figures 1-7As shown in the figure, two groups of first guiding components 211 are arranged on the front surface of the first hole-making frame 21; the first tensioning mechanism 4 includes a first hole-making seat 41 fixed on the front surface of the first hole-making frame 21. Two fixing plates 42 are arranged opposite to each other left and right on the front surface of the first hole-making seat 41. A first sliding rod 43, a driving shaft 44 and a plurality of first sliding seats 45 are arranged between the two fixing plates 42. The first sliding rod 43 is fixed on the fixing plate 42. The driving shaft 44 is rotatably connected between the two fixing plates 42. The first sliding seat 45 is slidably connected to the first sliding rod 43. A first driving component is fixed on the back surface of the first hole-making seat 41. The first driving component is used to drive the driving shaft 44 to rotate. Multiple first guiding slots 441 are arranged on the driving shaft 44 to the left and right respectively with the axis of the driving shaft 44 as the reference point. A first sliding block 47 is slidably connected in the first guiding slot 441. One end of the first sliding block 47 extends out of the first guiding slot 441 and is connected to the first sliding seat 45. First driving rollers 48 are arranged on the front surfaces of the first sliding seats 45. Adjacent two first driving rollers 48 are respectively arranged near the top and bottom of the first sliding seat 45. The two groups of first guiding components 211 are respectively arranged symmetrically left and right on the first hole-making seat 41; any one group of the first guiding components 211 includes two first guiding driving shafts arranged parallel to each other up and down. A first roller gap is formed between the two first guiding driving shafts. A first liquid injection pipe 111 and a first liquid discharge pipe 112 are arranged on one side of the first hole-making slot 11. The first liquid injection pipe 111 and the first liquid discharge pipe 112 are respectively arranged near the top and bottom of the first hole-making slot 11; in this embodiment, since the hole-making of the aluminum foil 10 depends on the random attack of chloride ions in the mixed acid solution on the foil surface, the mixed acid solution needs to be frequently replaced. Each time the mixed acid solution is replaced, liquid flow will be generated, causing the very thin aluminum foil to swing up and down with the liquid flow. When the liquid flow is generated in the mixed acid solution, the first driving component drives the driving shaft 44 to rotate. The rotation of the driving shaft 44 drives the first sliding block 47 to slide along the first guiding slot 441. At the same time, the first sliding seat 45 slides along the first sliding rod 43, so that multiple first sliding seats 45 approach or move away from each other, tensioning the aluminum foil 10, preventing the aluminum foil 10 from swinging up and down in the liquid flow, improving the uniformity and quantity of the overall hole-making of the aluminum foil, having a good hole-making effect, and improving the specific volume of the electrode foil.

[0033] As shown in the attached Figures 1-7 figure, a first driven wheel 442 is arranged at one end of the driving shaft 44; the first driving component includes a first stepping motor 461 fixed on the back surface of the first hole-making seat 41. A first driving wheel 462 is drivingly connected to the output shaft of the first stepping motor 461. The first driving wheel 462 and the first driven wheel 442 are connected by a first belt 463; in this embodiment, the first stepping motor 461 drives the first driving wheel 462 to rotate. The first driving wheel 462 drives the first driven wheel 442 and the driving shaft 44 to rotate through the first belt 463.

[0034] As shown in the attached Figures 1-7 figure, two sets of second guiding components 221 are arranged on the front surface of the film removing frame 22, and a plurality of ultrasonic generators are symmetrically embedded on the front and rear inner side walls of the film removing groove 12; the film removing mechanism 5 includes a film removing plate 51, a plurality of film removing grooves 511 arranged on the front surface of the film removing plate 51, a film removing slide seat 52 slidably connected up and down in the film removing grooves 511, a second driving roller 53 arranged on the front surface of the film removing slide seat 52, a film removing motor 54 arranged at one end of the film removing groove 511, a film removing lead screw 55 drivenly connected to the output shaft of the film removing motor 54, a film removing internal threaded hole oppositely arranged on the film removing slide seat 52 to the film removing lead screw 55, and the two sets of second guiding components 221 are respectively arranged on the film removing plate 51 in left and right symmetry; any one set of the second guiding components 221 includes two second guiding driving shafts arranged in parallel up and down, a second roller gap is formed between the two second guiding driving shafts, a second liquid injection pipe 121 and a second liquid discharge pipe 122 are arranged on one side of the film removing groove 12, and the second liquid injection pipe 121 and the second liquid discharge pipe 122 are respectively arranged near the top and the bottom of the film removing groove 12; in this embodiment, to ensure that the aluminum sulfate film attached to the surface of the aluminum foil 10 can be completely removed, the film removing motor 54 drives the film removing lead screw 55 to rotate, the film removing lead screw 55 drives the film removing slide seat 52 to slide along the film removing groove 511, so that the second driving rollers 53 on the adjacent film removing slide seats 52 are respectively close to the top end and the bottom end of the film removing groove 511, so that the aluminum foil 10 is wound around the adjacent second driving rollers 53 in an S shape, increasing the contact area between the aluminum foil 10 and the fluosilicic acid solution and prolonging the contact time between the aluminum foil 10 and the fluosilicic acid solution, and the aluminum sulfate film on the surface of the foil surface 10 is removed more completely.

[0035] As shown in the attached Figures 1-7As shown in the figure, two sets of third guiding components 231 are arranged on the front surface of the second hole punching frame 23; the second tensioning mechanism 6 includes a second hole punching seat 61 fixed on the front surface of the second hole punching frame 23. On the front surface of the second hole punching seat 61, two fixing plates 62 are arranged opposite to each other left and right. Between the two fixing plates 62, a second sliding rod 63, a second driving shaft 64 and a plurality of second sliding seats 65 are arranged. The second sliding rod 63 is fixed on the fixing plates 62. The second driving shaft 64 is rotatably connected between the two fixing plates 62. The first sliding seat 45 is slidably connected to the second sliding rod 63. A second driving component is fixed on the back surface of the second hole punching seat 61. The second driving component is used to drive the second driving shaft 64 to rotate. On the second driving shaft 64, a plurality of guiding slots 641 are arranged respectively to the left and right with the axis of the second driving shaft 64 as the reference point. A second sliding block 67 is slidably connected in the guiding slots 641. One end of the second sliding block 67 extends out of the guiding slots 641 and is connected to the second sliding seat 65. Third driving rollers 68 are arranged on the front surfaces of the second sliding seats 65. Adjacent two of the third driving rollers 68 are respectively arranged near the top and bottom of the second sliding seat 65. The two sets of third guiding components 231 are respectively arranged symmetrically to the left and right on the second hole punching seat 61; any one set of the third guiding components 231 includes two third guiding driving shafts arranged parallel to each other up and down. A third roller gap is formed between the two third guiding driving shafts. A third liquid injection pipe 131 and a third liquid discharge pipe 132 are arranged on one side of the second hole punching groove 13. The third liquid injection pipe 131 and the third liquid discharge pipe 132 are respectively arranged near the top and bottom of the second hole punching groove 13. In this embodiment, since the hole punching of the aluminum foil 10 depends on the random attack of chloride ions in the mixed acid solution on the foil surface, the mixed acid solution needs to be replaced frequently. Each time the mixed acid solution is replaced, liquid flow will be generated, causing the very thin aluminum foil to swing up and down with the liquid flow. When liquid flow is generated in the mixed acid solution, the second driving component drives the second driving shaft 64 to rotate. The rotation of the second driving shaft 64 drives the second sliding block 67 to slide along the guiding slots 641. At the same time, the second sliding seat 65 slides along the second sliding rod 63, causing the plurality of second sliding seats 65 to approach or move away from each other, tensioning the aluminum foil 10, preventing the aluminum foil 10 from swinging up and down in the liquid flow, improving the uniformity and quantity of the overall hole punching of the aluminum foil, achieving good hole punching effect, and enhancing the specific volume of the electrode foil.

[0036] As shown in the attached Figures 1-7 figure, one end of the second driving shaft 64 is provided with a second driven wheel 642; the second driving component includes a second stepping motor 661 fixed on the back surface of the second hole punching seat 61. A second driving wheel 662 is drivingly connected to the output shaft of the second stepping motor 661.
