Description

Technical Field

[0001] The present invention relates to the technical field of copper foil production, and particularly relates to a surface treatment machine for both rolling and electrolytic thick copper foils. Background Art

[0002] The copper foil industry has developed rapidly, and various new types of copper foils have been gradually widely applied. Among them, due to its excellent conductivity and superiority in high-frequency signal transmission, rolled copper foil is increasingly used in various devices such as high-current and 5G high-frequency transmission equipment. Electrolytic thick foil usually refers to electrolytic copper foil with a thickness exceeding 105 microns, and is gradually being applied in new energy and 5G power equipment. However, there are relatively few surface treatment equipment for thick copper foils in China. Most manufacturers are still using ordinary copper foil treatment machines for production, which has a great impact on product quality and so on.

[0003] The application publication number is CN119287368A, which discloses a surface treatment machine and treatment process for carrier copper foil. Combining its specification and drawings, its solution is that the lifting component drives the adjusting roller to immerse in or away from the solutions in the electroless plating tank, electroplating tank and anti-oxidation tank, so that the immersion time of the carrier copper foil in the solution can be adjusted as needed to produce copper foils with different thicknesses.

[0004] The process of producing copper foil using this equipment still has limitations: 1. Since thick copper foil and rolled copper foil have different physical properties, this equipment cannot simultaneously meet different process requirements and cannot simultaneously achieve the surface treatment of thick copper foil and rolled copper foil. The equipment has poor versatility and single function, which brings inconvenience to the production process; 2. When the copper foil surface treatment machine switches between different functional tanks, for example, when the copper foil extends into the cleaning pool from the electroless plating tank, how to effectively remove the excess chemical components contaminated on the copper foil surface in combination with the cleaning pool is also one of the problems that need to be considered.

[0019] The present invention will be further described below in conjunction with the embodiments shown in the drawings: As Figure 8 And Figure 9 Shown, a calendering and electrolytic thick copper foil dual-purpose surface treatment machine, the first embodiment of the present invention: includes an equipment frame 1, and four function slots 2 arranged inside the equipment frame 1. The four function slots 2 are two electrolytic degreasing slots and two water washing slots in sequence from left to right.

[0020] Inside at least one electrolytic degreasing tank, there are four anode plates 21. The reverse electroplating function of the four anode plates 23 enables a large number of cleaning bubbles to be generated in the degreasing liquid in the tank under the action of current, effectively cleaning the grease remaining on the surface of the rolled copper foil during the rolling process, so that the oil content rate on the surface of the copper foil meets the requirements of subsequent surface treatment.

[0021] Inside each water washing tank, there are several cleaning pipelines 22. The nozzles at the ends of the cleaning pipelines 22 are aligned with the surface of the copper foil, and pure water is used to spray and wash the surface of the copper foil to ensure that the remaining degreasing liquid will not be carried into the subsequent roughening and curing functional tanks.

[0022] In traditional copper foil electroplating treatment equipment, there are no electrolytic degreasing tanks and water washing tanks. When producing electrolytic thick copper foil, the copper foil can directly bypass the electrolytic degreasing tank and enter the roughening, curing and other electroplating processes after passing through the water washing tank.

[0023] For the grease or lubricating oil remaining on the surface of the rolled copper foil during the rolling process, the electrolytic degreasing tank and the water washing tank can effectively clean it. After the degreasing and water washing are completed, the copper foil is subjected to standard copper foil surface treatments such as roughening, curing, galvanizing, nickel plating, chromium plating, and silane spraying. The electroplating and water washing modes are also adopted to ensure that different plating solutions will not be mixed while meeting the requirements of copper foil surface treatment.

[0024] The solution of the first embodiment can be directed at the physical properties of thick copper foil and rolled copper foil, and in combination with the process requirements of post-treatment in copper foil production, on the basis of an ordinary copper foil processing machine, the functional tanks are redesigned to enable it to meet the operation requirements of rolled and electrolytic thick copper foil.

[0025] In order to more effectively realize the structural functions: in the first embodiment, several first guide roller mechanisms 3 for conveying copper foil are provided above the equipment frame 1. Between adjacent first guide roller mechanisms 3 above the electrolytic degreasing tank, there is a second guide roller mechanism 4 capable of conducting current to the surface of the copper foil. Between adjacent first guide roller mechanisms 3 above the water washing tank, there is a third guide roller mechanism 5 for wiping the residual liquid on the surface of the copper foil. At the bottom of each functional tank 2, there is a hydraulic roller 23 that can rotate, and the hydraulic roller 23 is driven by a coupling and an external third drive motor 24.

[0026] The first guide roller mechanism 3 includes first roller shaft support plates 31 arranged on both sides of the equipment frame 1 and first guide rollers 32 hinged between adjacent first roller shaft support plates 31.

[0027] The second guide roller mechanism 4 includes a second roller shaft support plate 41 and a second conductive roller 42 hinged between adjacent second roller shaft support plates 41. The interior of the second conductive roller 42 is hollow and connected to an external water cooling pipeline 43. A conductive copper ring is further provided at the end of the second conductive roller 42, and the conductive copper ring is connected to a conductive copper plate 44.

[0028] When designing the second conductive roller 42, in addition to increasing the bearing capacity and the diameter of the roller shaft, the roller surface also needs to be made of Hastelloy material to cope with the electrical and mechanical damage to the roller surface during the conduction of thick copper foil.

[0029] During the rotation process of the second conductive roller 42, the conductive copper ring is always driven to rotate, and the conductive copper ring always fits against the end of the conductive copper plate 44. The conductive copper plate 44 can conduct low-voltage current to the second conductive roller 42, and the second guide roller 42 transfers the current to the copper foil, making the second conductive roller 42 in an energized state, so as to facilitate subsequent other processes to treat the surface of the copper foil.

[0030] A second lifting cylinder 45 is provided at the top of each second roller shaft support plate 41. The piston rod end of the second lifting cylinder 45 is connected to a second pressure roller 46, and the second pressure roller 46 can adjust the tension on the surface of the copper foil on the second conductive roller 42 and wipe the liquid on the surface of the copper foil.

[0031] The hydraulic roller 23 is driven by an independent third drive motor 24. Both the first guide roller 32 and the second conductive roller 42 have independent drive mechanisms 6 for their respective self-rotation. Therefore, during the movement process, the hydraulic roller 23, the first guide roller 32, and the second conductive roller 42 can drive the copper foil for conveying, and the copper foil will pass through two electrolytic degreasing tanks and two water washing tanks in sequence during the conveying process. The second pressure roller 46 above the two electrolytic degreasing tanks can change its height under the control of the second lifting cylinder 45, so as to preliminarily wipe the grease on the surface of the copper foil and also play a role in adjusting the tension at the same time.

[0032] In order to make the two water washing tanks have a better cleaning effect on the copper foil, the third guide roller mechanism 5 includes a third roller shaft support plate 51, a third guide roller 52, a third gear 53, a third lifting cylinder 54, and a third pressure roller 55. Each third roller shaft support plate 51 is arranged on the side of the equipment frame 1. A third guide roller 52 is rotatably provided inside adjacent third roller shaft support plates 51. The end of the third guide roller 52 is connected to a third gear 53. A third lifting cylinder 54 is provided at the top of each third roller shaft support plate 51. The piston rod end of the third lifting cylinder 54 is connected to a third pressure roller 55, and the third pressure roller 55 can wipe the liquid on the surface of the copper foil on the third guide roller 52.

[0033] Similarly, the copper foil will pass through two washing tanks in turn during the conveying process. The third pressing roller 55 above the two washing tanks can change its height under the control of the third lifting cylinder 54, so as to wipe off the grease on the surface of the copper foil and also play a role in adjusting the tension.

[0034] The second pressing roller 46 and the third pressing roller 55 rotate under the movement trend of the copper foil. The second pressing roller 46 and the third pressing roller 55 are made of fluororubber with relatively high hardness, and the designed hardness is 65-70 degrees Shore, which can not only meet the function of the pressing roller for squeezing water and liquid, but also can cope with the mechanical damage of thick copper foil to rubber.

[0035] The second pressing roller 46 and the third pressing roller 55 adopt the cylinder vertical motion mode, which can effectively enhance the operation automation of the pressing rollers and facilitate the adjustment of the pressing roller force to suit the pressing force of copper foils of different thicknesses and strengths.

[0036] The third gear 53 is connected to the driving mechanism 6 by transmission. The ends of the first guide roller 32 and the second conductive roller 42 are connected to the first gear 33 and the second gear 47 respectively. The first gear 33 and the second gear 47 are connected to the driving mechanism 6 by transmission.

[0037] The driving mechanism 6 includes a motor supporting column 61, a fourth driving motor 62 and a fourth gear 63. The motor supporting column 61 is arranged on the outside of the equipment frame 1. The top of the motor supporting column 61 is connected to the fourth driving motor 62. The fourth gear 63 is installed at the end of the rotating shaft of the fourth driving motor 62. The fourth gear 63 is connected to the first gear 33 or the second gear 47 or the third gear 53 through a transmission chain.

[0038] During the rotation of the shaft of the fourth drive motor 62, the fourth gear 63 can drive the transmission chain to reciprocate, and different transmission chains respectively drive the first gear 33 or the second gear 47 or the third gear 53 to rotate, thereby driving the first guide roller 32, the second conductive roller 42 and the third guide roller 52 to rotate.

[0039] In order to achieve better cleaning effect of copper foil when passing through the water washing tank, please refer to Figure 1 and Figure 2 , the second embodiment of the present invention. The difference from the first embodiment is that: a guide roller support frame 7 is further provided above the device frame 1, a belt tensioning roller 71 is hingedly connected inside the guide roller support frame 7, a revolving belt 72 for wiping liquid is provided on the surface of the third pressure roller 55 and the surface of the belt tensioning roller 71, and a bottom of one side of the revolving belt 72 is in contact with the surface of the copper foil on the third guide roller 52.

[0040] Since the effective wiping area of the third pressure roller 55 itself is small, after wiping the copper foil on the surface of the third guide roller 52 for a period of time, too much water accumulates on the surface, thus significantly reducing the wiping effect. However, in the second embodiment, the third pressure roller 55 can drive the rotary belt 72 simultaneously during rotation. The rotary belt 72 has a larger area and can effectively carry away the accumulated water during this rotary motion.

[0041] Please continue to refer to Figures 3 to 5 , in order to further accelerate the treatment of the water on the surface of the rotary belt 72. Inside the guide roller support frame 7, there is also a cleaning roller shaft 73 that can slide up and down and rotate. On the surface of the cleaning roller shaft 73, there are several deformable flexible strips 711. The flexible strips 711 of the cleaning roller shaft 73 can wipe and remove the liquid contaminated on the rotary belt 72.

[0042] The cleaning roller shaft 73 includes several roller shaft connection blocks 731 and a cleaning sleeve 732. Each roller shaft connection block 731 is rotatably connected to the inside of the guide roller support frame 7. The cleaning sleeve 732 is detachably installed between adjacent roller shaft connection blocks 731. Inside the cleaning sleeve 732, there is also an air duct 74. One end of the air duct 74 passes through a roller shaft connection block 731 until the outside. On the surface of the air duct 74, several blowing channels 741 extend outward in a divergent manner. The blowing channels 741 pass through the inner wall of the cleaning sleeve 732 until the outside. The air outlet of each blowing channel 741 is located between adjacent flexible strips 711.

[0043] Since the inside of the cleaning roller shaft 73 is a hollow structure, it can be filled with a heat-conducting liquid. The external gas enters through the air duct 74, and the entering gas can be a heated gas. These gases with heat flow inside the air duct 74 to each blowing channel 741 until they are blown to the outside. The blowing channels 741 can be made of aluminum alloy with good heat transfer effect. Therefore, the gases with heat can use the outer wall of the blowing channels 741 to heat the heat-conducting liquid, so that the entire cleaning roller shaft 73 is in a state with a relatively high temperature.

[0044] Then, under the blowing force of the blowing channels 741, the high temperature of the cleaning roller shaft 73, and the wiping action of the flexible strips 711, the liquid remaining on the surface of the rotary belt 72 can be efficiently removed, so that the rotary belt 72 can maintain the best cleaning effect for a long time.

[0045] Please continue to refer to Figure 6 and Figure 7, in order to replace the cleaning sleeve 732 without affecting the normal production of copper foil by the whole device, or to perform positioning maintenance on the cleaning sleeve 732, such as manual wiping, it is necessary to effectively adjust the position of the cleaning sleeve 732, that is, to achieve the height control of the cleaning sleeve 732.

[0046] Since the rotation of the rotary belt 72 is driven by the driving force of the third guide roller 52 to drive the third pressure roller 55 to move reciprocally. Therefore, the setting of the cleaning sleeve 732 cannot affect the normal rotation speed of the rotary belt 72 and can be specifically adapted to the rotation speed of the third guide roller 52. So after the cleaning sleeve 732 realizes the height change, it also needs to have the function of self-rotation. The height change and self-rotation of the cleaning sleeve 732 can adaptively adjust the pressure on the rotary belt 72, so as to achieve the cleaning effect for different speeds. The side wall of the equipment frame 1 is also installed with an equipment side plate 11. The side of the equipment side plate 11 is connected with a lifting support shell 8 through a limiting column. The side of the lifting support shell 8 is provided with an adjusting support arm 81 that can slide up and down. The bottom side of the adjusting support arm 81 is hinged and connected with a second transmission gear 82. A plurality of metal springs 83 are arranged between the top of the adjusting support arm 81 and the top of the lifting support shell 8. Each metal spring 83 is internally provided with a lifting guide rod 84. One end of the lifting guide rod 84 is fixedly connected to the top of the lifting support shell 8, and the other end of the lifting guide rod 84 is slidably connected to the inside of the adjusting support arm 81. The rotation of the first transmission gear 85 is driven by the rotating shaft of the first driving motor 86.

[0047] The top surface of the lifting support shell 8 is also rotatably provided with a first transmission gear 85. The inside of the first transmission gear 85 is threadedly connected with a screw rod 87. The end of the screw rod 87 is hinged and connected to the side plate of the adjusting support arm 81. The inside of the lifting support shell 8 is rotatably provided with a fifth transmission gear 9 and a gear support shaft 91. The gear support shaft 91 is provided with a third transmission gear 92 and a fourth transmission gear 94. The fourth transmission gear 94 is located inside the lifting support shell 8, and the third transmission gear 92 is located outside the side of the lifting support shell 8. The second transmission gear 82 and the third transmission gear 92 are connected by a first transmission belt 93. The fourth transmission gear 94 and the fifth transmission gear 9 are connected by a second transmission belt 95. The side of the equipment side plate 11 is also provided with a second driving motor 96. The rotating shaft of the equipment side plate 11 extends into the inside of the lifting support shell 8 and is connected to the fifth transmission gear 9. The fifth transmission gear 9, the gear support shaft 91 and the second transmission gear 82 are arranged in sequence from top to bottom relative to the surface of the guide roller support frame 7.

[0048] The cleaning roller 73 is driven by the second transmission gear 82. Therefore, adjusting the height of the gear of the second transmission gear 82 can adjust the height of the cleaning roller 73. During the rotation of the rotating shaft of the first drive motor 86, the first transmission gear 85 can be driven to rotate. The first transmission gear 85 drives the screw 87 to rotate by means of external teeth. Therefore, the screw 87 can generate a displacement of rising or falling. The position change of the screw 87 can simultaneously drive the adjusting support arm 81 to slide up and down on the side of the lifting support housing 8, and finally change the height of the second transmission gear 82 at the end of the adjusting support arm 81.

[0049] To avoid the pressing effect of the cleaning roller 73 on the rotary belt 72 after the height change, or to prevent the cleaning roller 73 from jamming with the rotary belt 72, after the screw 87 adjusts the height of the adjusting support arm 81, when the cleaning roller 73 is subjected to a force exceeding the set force, the force will be transmitted to the adjusting support arm 81 through the second transmission gear 82. At this time, the metal spring 83 will deform, and the lifting guide rod 84 will slide inside the adjusting support arm 81.

[0050] It should be noted that the end of the screw 87 can limit the downward movement of the adjusting support arm 81, but the end of the screw 87 cannot limit the upward sliding of the adjusting support arm 81. And when the metal spring 83 is in a compressed state, it indicates that the height adjustment is incorrect at this time, which is convenient for self-adaptive adjustment of the height of the second transmission gear 82.

[0051] In order to enable the second transmission gear 82 to rotate normally during subsequent reset after the height change, after the height of the second transmission gear 82 changes, the second transmission belt 95 will deform to a certain extent, but there will be no interference with the upward movement of the adjusting support arm 81, which is convenient for subsequent workers to clean the dirt on the cleaning sleeve 732 or replace the cleaning sleeve 732.

[0052] When the second transmission gear 82 returns, after the rotating shaft of the second drive motor 96 rotates, the fifth transmission gear 9 can be driven to rotate. During the rotation of the fifth transmission gear 9, the entire gear support shaft 91 is driven to rotate through the third transmission gear 92. The gear support shaft 91 simultaneously drives the second transmission belt 95 to move through the fourth transmission gear 94, and the second transmission belt 95 drives the second transmission gear 82 to move normally.

[0053] The working principle and usage method of the present invention: During the rotation of the hydraulic roller 23, the first guide roller 32 and the second conductive roller 42, the copper foil can be conveyed. During the conveying process of the copper foil, it will successively pass through two electrolytic degreasing tanks and two water washing tanks.

[0054] When passing through the inside of the electrolytic degreasing tank, the reverse electroplating function of the four anode plates 23 causes a large number of cleaning bubbles to be generated in the degreasing liquid in the tank under the action of current, effectively cleaning the grease remaining on the surface of the rolled copper foil during the rolling process, so that the oil content rate on the surface of the copper foil meets the requirements of subsequent surface treatment.

[0055] When passing above the space between the two electrolytic degreasing tanks, the second pressure roller 46 can change its height under the control of the second lifting cylinder 45, thereby initially wiping the grease on the surface of the copper foil and also playing a role in adjusting the tension at the same time. When passing through the inside of the water washing tank, a number of cleaning pipelines 22 are provided inside each water washing tank.
