Description

Technical Field

[0001] This invention relates to the field of electrolytic copper foil production technology, and more particularly to a porous copper foil production line. Background Technology

[0002] Electrolytic copper foil is a core material for strategic industries such as electronics and information technology and new energy lithium batteries. With the rapid development of 5G communication, high-density integrated circuits and high-energy-density lithium battery technologies, the market demand for refined copper foil with special structures and functions (such as porous copper foil, ultra-thin copper foil, and surface patterned copper foil) is becoming increasingly urgent.

[0003] In recent years, the industry has proposed to prefabricate insulating shielding points on the surface of the cathode roller and then directly "grow" functional copper foil with predetermined pores or patterns through selective electrodeposition to achieve additive manufacturing, which has significant technical and economic advantages.

[0004] However, the cathode roller is immersed in high temperature, strong acid, and charged electrolyte for a long time and is subjected to mechanical peeling stress. The insulating shielding points on its surface are prone to aging, wear, and even partial detachment. Once the shielding points fail, it will directly lead to defects in the copper foil structure, resulting in the scrapping of a large number of products. Currently, the repair of shielding points requires the complete disassembly and hoisting of the cathode roller, which weighs several tons, from the production line to a special clean room for processing. The process is complicated and takes several days to several weeks, causing long-term shutdown of the production line and resulting in huge economic losses. Therefore, in order to solve the above problems, a porous copper foil production line is proposed. Summary of the Invention

[0005] The purpose of this invention is to address the shortcomings of existing technologies by proposing a porous copper foil production line.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: A porous copper foil production line includes an electrolytic cell, an anti-oxidation treatment device, a drying device, and a winding mechanism connected in sequence. A cathode roller is rotatably connected to the inner side of the electrolytic cell. A mounting box is circumferentially mounted on the top of the cathode roller and can move horizontally.

The polishing mechanism also includes a laser head for polishing the shielding area on the cathode roller; The two adjustment components are symmetrically arranged and include horizontally movable blocks. The laser head and the filling component are each circumferentially slidably arranged on the arc surfaces of the two movable blocks. The coating mechanism further includes a filling assembly, which includes a fixedly disposed outer cylinder, an inner cylinder rotatably connected to the inner side of the outer cylinder, a rotating connecting ring connected to the outer side of the inner cylinder, and a fixed connecting ring connected to the outer side of the outer cylinder. The rotating connecting ring can be connected to different agents, and the inner cylinder is used for spraying shielding materials.

[0007] The above technical solution further includes: An anode plate is fixedly connected to the inner side of the electrolytic cell. The anode plate is disposed between the electrolytic cell and the cathode roller, and there is a gap between the anode plate and the cathode roller.

[0009] The two gear rings are slidably mounted on a movable slide plate. The inner side of the movable slide plate is symmetrically connected to a movable gear, which meshes with the gear ring. A movable motor is fixedly mounted on the outer side of the movable slide plate. The output end of the movable motor is fixedly mounted to the two movable gears. The mounting box is fixedly connected between the two movable slide plates.

[0010] The adjustment assembly also includes an adjustment motor fixedly installed on one side of the mounting box. The output end of the adjustment motor is connected to an adjustment screw. The adjustment screw is rotatably connected to the mounting box. The adjustment screw is threadedly connected to the moving block. A limit slide plate is fixedly connected to the inner side of the mounting box. The moving block slides relative to the limit slide plate. An arc-shaped groove is provided on the arc surface of the moving block.

[0011] The inner side of the arc-shaped slide groove is provided with a second linear guide rail for limiting sliding. A second linear motor is moved on the second linear guide rail. Adjusting cylinders are rotatably connected to both sides of the moving block. The extension and retraction ends of the adjusting cylinders are rotatably connected to the second linear guide rail. The extension and retraction ends of the two adjusting cylinders are respectively located at the top and bottom of the second linear guide rail.

[0012] A second mounting base is mounted on the second linear motor of an adjustment component, and the laser head is fixedly mounted inside the second mounting base.

[0013] The filling assembly also includes a first mounting base, which is fixedly connected to a second linear motor of another adjustment assembly. The outer cylinder is fixedly connected to the inside of the first mounting base, and a rubber septum is fixedly connected to the bottom of the outer cylinder. The fixing ring is fixedly connected to the outer cylinder, and multiple external interfaces are fixedly connected to the outer circumferential array of the fixing ring.

[0014] The outer circumferential array of the rotating ring is fixedly connected to multiple inner interfaces. The outer side of the inner cylinder is provided with an annular groove, which is connected to the inner interfaces. The rotating ring is rotatably connected to the inner cylinder and is fixedly connected to the top of the outer cylinder. The top of the inner cylinder is provided with a connection port.

[0016] The present invention has the following beneficial effects: This invention enables online automated in-situ repair of failed shielding points on the cathode roller surface. It allows for precise detection, grinding, cleaning, pretreatment, and recoating of localized detachment points without removing the cathode roller from the production line, significantly reducing maintenance time.

[0020] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0021] Example 1

[0022] like Figures 1-13 As shown, the present invention proposes a porous copper foil production line, including an electrolytic cell 2, an anti-oxidation treatment device 5, a drying device 7, and a winding mechanism 8 connected in sequence. A cathode roller 21 is rotatably connected to the inner side of the electrolytic cell 2. A mounting box 14 is circumferentially mounted on the top of the cathode roller 21 and can move horizontally. A grinding mechanism and a coating mechanism are provided on the inner side of the mounting box 14. Both the grinding mechanism and the coating mechanism include adjustment components. The grinding mechanism also includes a laser head 4, used to grind the shielding area on the cathode roller 21; The two adjustment components are symmetrically arranged and include horizontally movable blocks 33. The laser head 4 and the filling component are respectively circumferentially slidably arranged on the arc surfaces of the two movable blocks 33. The coating mechanism further includes a filling assembly, which includes a fixedly disposed outer cylinder 38, an inner cylinder 310 rotatably connected to the inner side of the outer cylinder 38, a rotating connecting ring 313 connected to the outer side of the inner cylinder 310, and a fixed connecting ring 312 connected to the outer side of the outer cylinder 38. The rotating connecting ring 313 can be connected to different agents, and the inner cylinder 310 is used for spraying shielding materials.

[0023] In this invention, "shielded area" refers to a specific circular or patterned region on the surface of the cathode roller pre-defined for forming a porous structure. "Shielded point" refers to an insulating, acid-resistant material layer coated on the "shielded area". When referring to repair work, "failed shielded point" refers to a material layer that has fallen off or been damaged, and "shielded area to be repaired" refers to the corresponding area that needs to be recoated.

[0024] First, during the electrolytic copper foil production process, multiple shielding points are set on the cathode roller 21. The shielding points are made of insulating and acid-resistant coatings, the main components of which are organic coatings such as acrylic coatings or epoxy coatings that have insulating and acid-resistant properties. During the electrolysis process, the porous copper foil produced on the cathode roller 21 is then pickled, washed with water, and dried for pretreatment of the porous copper foil at the production site. Afterward, it passes through the separation roller, and then sequentially through the anti-oxidation treatment equipment 5, the drying equipment 7, and the winding mechanism 8.

[0025] The anti-oxidation treatment equipment 5, the drying equipment 7, and the winding mechanism 8 can be referenced to an integrated copper foil production and slitting production line disclosed in patent number CN108060437B.

[0026] The purpose of this design is that the shielding points are immersed in acidic electrolyte and will fall off after a long time. Therefore, in order to repair the shielding points by spraying without disassembling the cathode roller 21; Furthermore, a visual sensor is installed on the top inner side of the mounting box 14, which can detect whether there is a shielding point at the shielding area. If there is no shielding point, the shielding area is laser-polished by the laser head 4 in the polishing mechanism to polish it into a circle. Then, the shielding area is washed with water by the coating mechanism to remove the oxide layer. Then, the coating is sprayed onto the shielding area through the inner cylinder 310 and then dried.

[0027] Example 2

[0028] like Figure 2 As shown, based on Embodiment 1, in this embodiment, an electrolytic cell 2 is fixedly provided on the outer side of the cathode roller 21, and an anode plate 20 is fixedly connected to the inner side of the electrolytic cell 2. The electrolytic cell 2 and the cathode roller 21 are rotatably connected. The anode plate 20 is disposed between the electrolytic cell 2 and the cathode roller 21, and there is a gap between the anode plate 20 and the cathode roller 21. The anode plate 20 adopts a back-pull type, and is connected by bolts through the anode base and fastened with screws. During the electrolytic copper foil production process, the bottom of the cathode roller 21 is immersed in an acidic copper sulfate electrolyte. A direct current is connected between the cathode roller 21 and the anode plate 20. Copper ions in the electrolytic cell 2 are in dynamic equilibrium. The copper ions in the electrolyte gain electrons on the surface of the cathode roller 21, are reduced to copper atoms, and are deposited layer by layer. As the cathode roller 21 rotates at a constant speed, the continuously deposited copper layer reaches the required thickness and is then peeled off from the roller surface by the stripping roller to form a continuous perforated metal foil.

[0029] Example 3

[0030] like Figures 3-4 As shown, based on the above embodiments, in this embodiment, a base 1 is fixedly connected to the outside of the electrolytic cell 2, and a support plate 15 is fixedly connected to both sides of the base 1. A linear module is installed on the top of the support plate 15, and a gear ring 13 is symmetrically fixedly connected to the output end of the linear module.

[0031] Two gear rings 13 are slidably mounted on a movable slide plate 16. A movable gear 18 is symmetrically rotatably connected to the inner side of the movable slide plate 16. The movable gear 18 meshes with the gear rings 13. A movable motor 17 is fixedly mounted on the outer side of the movable slide plate 16. The output end of the movable motor 17 is fixedly mounted to the two movable gears 18. The mounting box 14 is fixedly connected between the two movable slide plates 16.

[0032] In this design, the linear module includes a first linear guide rail 10 and a first linear motor 12. Two gear rings 13 are fixedly mounted on the top of the first linear motor 12. In use, the first linear motor 12 is driven to move on the first linear guide rail 10. At the same time, the moving motor 17 is used in conjunction to adjust the position of the mounting box 14 and its position on the cathode roller 21. Furthermore, the two moving motors 17 are driven synchronously, and through the meshing action of the moving gear 18 and the gear ring 13, the moving slide plate 16 is made to move in a circular motion on the gear ring 13, thereby realizing the control of the circular motion of the mounting box 14.

[0033] If the cathode roller 21 is to be disassembled for maintenance, the moving motor 17 can be driven to move the mounting box 14 to one side of the cathode roller 21. Then the first linear motor 12 is started to disengage the mounting box 14 from the cathode roller 21 without interfering with the disassembly and assembly process of the cathode roller 21. During the installation of the cathode roller 21, the moving motor 17 is started to move the mounting box 14 to one side of the cathode roller 21. Then the first linear motor 12 is started to make the mounting box 14 contact the cathode roller 21. Then the first linear motor 12 and the moving motor 17 are started simultaneously to move the mounting box 14 to directly above the cathode roller 21.

[0034] Example 4

[0035] like Figures 5-9As shown, based on the above embodiments, in this embodiment, the adjustment assembly further includes an adjustment motor 32 fixedly installed on one side of the mounting box 14. The output end of the adjustment motor 32 is connected to an adjustment screw 31. The adjustment screw 31 is rotatably connected to the mounting box 14. The adjustment screw 31 is threadedly connected to the moving block 33. A limiting slide plate 30 is fixedly connected to the inner side of the mounting box 14. The moving block 33 slides relative to the limiting slide plate 30. An arc-shaped groove 330 is provided on the arc surface of the moving block 33.

[0036] The inner side of the arc-shaped slide groove 330 is provided with a second linear guide rail 35 for limiting sliding. A second linear motor 36 is moved on the second linear guide rail 35. Adjusting cylinders 34 are rotatably connected to both sides of the moving block 33. The extension and retraction ends of the adjusting cylinders 34 are rotatably connected to the second linear guide rail 35. The extension and retraction ends of the two adjusting cylinders 34 are located at the top and bottom of the second linear guide rail 35, respectively.

[0037] A partition 3 is fixedly connected to the inside of the mounting box 14. The partition 3 is used to separate the grinding mechanism and the coating mechanism. Furthermore, during the repair process of the cathode roller 21, the shielding area of ​​the detached shielding point is polished, and the surface roughness Ra needs to be in the range of 0.1 to 0.2 micrometers. The vision sensor on the top of the inner side of the mounting box 14 has detected a missing shielding point during the rotation of the cathode roller 21. Therefore, by controlling the rotation of the moving motor 17 and the cathode roller 21, the point is moved to a position parallel to the laser head 4. Furthermore, the adjustment motor 32 of the grinding mechanism is then activated to drive the adjustment screw 31 to rotate, which in turn moves the moving block 33, causing the laser head 4 to move to that position. Since the surface of the cathode roller 21 has an arc, the laser head 4 slides on the arc surface of the moving block 33 by driving the adjustment cylinder 34. The two adjustment cylinders 34 extend and retract in opposite directions, thereby adjusting the angle of the laser head 4 so that the emitting end of the laser head 4 is perpendicular to that position. Furthermore, the surface of the cathode roller 21 is curved, and the area to be polished is a circle. The height of each point in the circular area relative to the laser head 4 is different. In order to prevent the focus of the laser head 4 from changing constantly during the polishing process, the height of the second mounting base 40 is adjusted by the second linear motor 36 that drives the polishing mechanism. A polarizing mirror is installed inside the laser head 4 to ensure that the laser head 4 hits every point.

[0038] Furthermore, when manufacturing shielding points of 250–300 micrometers, the precision of adjusting screw 31 needs to be controlled within 50 micrometers; Furthermore, the first mounting base 311 of the filling component needs to move synchronously with the laser head 4. After the shielding area is polished, since the two adjustment components are symmetrically arranged, after the cathode roller 21 rotates at a certain angle, the inner cylinder 310 of the filling component can be closed at this point. Then, the two adjustment cylinders 34 of the coating mechanism are driven so that the spray end of the inner cylinder 310 is perpendicular to this point. Then, the second linear motor 36 of the coating mechanism is started so that the rubber septum 39 contacts the cathode roller 21 and is squeezed to deform. At this time, the outer cylinder 38 and the inner cylinder 310 are in a relatively sealed state.

[0039] Example 5

[0040] like Figures 10-13 As shown, based on the above embodiments, in this embodiment, a second mounting base 40 is installed on the second linear motor 36 of an adjustment component, and the laser head 4 is fixedly installed inside the second mounting base 40.

[0041] The filling assembly also includes a first mounting base 311, which is fixedly connected to another adjustment assembly, a second linear motor 36. An outer cylinder 38 is fixedly connected to the inside of the first mounting base 311. A rubber septum 39 is fixedly connected to the bottom of the outer cylinder 38. A fixing ring 312 is fixedly connected to the outer cylinder 38. Multiple external interfaces 3120 are fixedly connected to the outer circumferential array of the fixing ring 312.

[0042] The outer circumferential array of the rotating ring 313 is fixedly connected to multiple inner interfaces 3130. The outer side of the inner cylinder 310 is provided with an annular groove 317, which is connected to the inner interfaces 3130. The rotating ring 313 is rotatably connected to the inner cylinder 310 and is fixedly connected to the top of the outer cylinder 38. The top of the inner cylinder 310 is provided with a connection port 3100. During the process of supplementing the shielding points, the internal interface 3130 is designed to have four connections: one is connected to the cleaning agent, one is connected to the removal agent, one is connected to the hot air, and the last one is connected to the deionized water. The cleaning agent is composed of an ethanol solution, and the removal agent is composed of a 10% dilute nitric acid solution. Furthermore, the number of external interfaces 3120 is the same as that of internal interfaces 3130, and each function corresponds to the other.

[0043] Furthermore, the rubber septum 39 then contacts the cathode roller 21, and subsequently the solenoid valve of the inner interface 3130 of the cleaning agent is activated, while the solenoid valves of other inner interfaces 3130 are closed. At the same time, the outer interface 3120 corresponding to the fixed connecting ring 312 is connected to negative pressure, and the solenoid valves on other outer interfaces 3120 are closed. The cleaning agent flows from the spray end of the inner cylinder 310 through the shielded area after grinding, and then passes through the outer cylinder 38 and is discharged from the outer interface 3120 on the fixed connecting ring 312, thus removing the oil stains present during the laser grinding process. Furthermore, similarly, deionized water is injected into the inner cylinder 310 from an inner port 3130, contacts the shield on the cathode roller 21, flows through the outer cylinder 38, and is discharged from the corresponding outer port 3120 to clean the cleaning agent residue. Furthermore, the remover is injected into the inner cylinder 310 from an inner port 3130, contacts the shield on the cathode roller 21, flows through the outer cylinder 38, and is discharged from the corresponding outer port 3120 to remove the oxide layer generated by laser polishing at the shield; then the remover is cleaned with deionized water.

[0044] Furthermore, hot air is then injected into the inner cylinder 310 from an inner port 3130, comes into contact with the shield on the cathode roller 21, flows through the outer cylinder 38, and is discharged from the corresponding outer port 3120, drying the shield.

[0045] A driven gear 314 is fixedly connected to the top outer side of the inner cylinder 310. A driving gear 315 is meshed with the outer side of the driven gear 314. A motor fixing plate 37 is fixedly connected to the top of the first mounting base 311. A coating motor 316 is fixedly installed on the top of the motor fixing plate 37. The output end of the coating motor 316 is fixedly installed with the driving gear 315.

[0046] Furthermore, after the above pretreatment work is completed, the shielding points are sprayed. The insulating and acid-resistant coating is an organic coating with insulating and acid-resistant properties, such as acrylic coating or epoxy coating. The gas propellant is a chemically stable propellant that is a liquid organic compound after being mixed with the coating under pressure. The gas propellant can be propane or butane, etc.

[0047] Furthermore, during the spraying operation, all solenoid valves of the inner interface 3130 are closed, and only one solenoid valve on the outer interface 3120 is open. The mixed organic coating enters from the connection port 3100 and is sprayed out from the spray end of the inner cylinder 310. By starting the coating motor 316, the inner cylinder 310 is rotated, making the shielding point more uniform. At the same time, one solenoid valve on the outer interface 3120 is opened (this outer interface 3120 corresponds to the inner interface 3130 that connects to hot air), and the gaseous propellant is recovered from this outer interface 3120. Furthermore, after the spraying is completed, the internal interface 3130 solenoid valve for connecting hot air is opened, and the hot air passes through the shielded points that have just been sprayed for drying.

[0048] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
