Description

Technical Field

[0001] The invention relates to the technical field of copper foil coating machines, in particular to a roll-to-roll continuous processing device for an anti-corrosion film on the surface of a copper foil. Background Art

[0002] Coating copper foil with an anti-corrosion film is a key process to improve its corrosion resistance and extend its life, especially in high-frequency, high-speed, high-heat-resistant and harsh environment applications. Due to the small thickness of the copper foil, wrinkles may occur during the conveying and coating process. After searching, the patent with application number CN202220848137.2 discloses an improved conveying structure for copper foil coating wrinkles. The conveying path of the coated copper foil after the drying process is further optimized to improve the improvement effect of the copper foil coating wrinkles, and effectively improve the overall processing yield of lithium batteries.

[0003] The above-mentioned device uses a pressure roller to extrude the copper foil to improve the wrinkles on the copper foil. This process will push the copper foil to bend. It will not have any effect before the copper foil is coated with an anti-corrosion film. However, after the copper foil is coated with an anti-corrosion film, the copper foil will continue to be squeezed. Even if the extrusion method is adopted from the uncoated side below the copper foil, the bending process of the copper foil will easily cause the solidified anti-corrosion film to crack, and the unsolidified anti-corrosion film will also be stretched at the bend, causing the thickness of the film to change. This process will affect the copper foil passing through the pressure roller, so that the area of the copper foil affected is larger, and the possibility of defects in the anti-corrosion film coated on the copper foil is increased.

DETAILED DESCRIPTION

[0021] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0022] Example 1 In order to solve the problem that the anti-corrosion film may be cracked or stretched when the copper foil is squeezed to improve the surface wrinkles, thereby increasing the defects of the anti-corrosion film on a larger area of the copper foil, please refer to Figure 1-Figure 5 This embodiment proposes a roll-to-roll continuous processing device for copper foil surface anti-corrosion film, including a copper foil coating machine main body 1, on which a lateral traction component 3 for smoothing the surface of the copper foil 2 is installed. The lateral traction component 3 includes a support frame 31, a telescopic rod 32, a contact head component 33, a down-pressing component 34 and a spring 35. The support frame 31 is installed on the copper foil coating machine main body 1, and the two telescopic rods 32 are both rotatably connected to the support frame 31. The spring 35 is installed between the telescopic rod 32 and the support frame 31, the contact head component 33 is installed on the top of the telescopic rod 32, and the down-pressing component 34 is installed on the top of the support frame 31. The telescopic rod 32 is driven by the down-pressing component 34.

[0023] During use, the copper foil is conveyed after passing through the round roller on the copper foil coater main body 1, so that the uncoated copper foil passes through the copper foil coater main body 1 from the winding rod to be coated with the anti-corrosion film, and then the coated and cured copper foil is rewound and stored to achieve the process of coating the anti-corrosion film on one side of the copper foil. After the copper foil is coated with the anti-corrosion film on the copper foil coater main body 1, the transverse traction component 3 stretches the copper foil from the lower surface to eliminate the wrinkles on the copper foil. The specific process is as follows: In the initial state, the spring 35 pushes the telescopic rod 32 and the contact head assembly 33 to rise. At this time, the angle between the telescopic rod 32 and the vertical direction is the smallest. When the copper foil passes around the round roller on the copper foil coater body 1 and passes over the horizontal traction assembly 3, the contact head assembly 33 contacts the lower surface of the copper foil, and the pressing assembly 34 is started. The pressing assembly 34 pushes the two telescopic rods 32 to rotate and gradually move away. The telescopic rod 32 drives the contact head assembly 33 to rotate. When the contact head assembly 33 rotates and descends, it pulls the telescopic rod 32 to extend to keep the contact head assembly 33 always moving along the lower surface of the copper foil.

[0024] When the two contact head assemblies 33 gradually move away from each other, the copper foil is pulled to extend from the middle of the two contact head assemblies 33 to both sides, thereby stretching the wrinkled copper foil flat. Then, the pressing assembly 34 drives the two telescopic rods 32 to rotate to the starting point, and the telescopic rods 32 drive the contact head assembly 33 to rotate to the starting point. In order to reduce the wrinkles in the copper foil caused by the gradual movement of the contact head assemblies 33, the suction force of the contact head assembly 33 can be controlled in stages, so that the suction force decreases when the two contact head assemblies 33 move gradually closer. Repeating the above process can stretch the copper foil to both sides from one point along the moving direction of the copper foil, so that the copper foil generates an external force that is stretched to both sides along the moving direction. The copper foil surface is smoothed by pulling from both ends along the direction of the copper foil, which will not squeeze the copper foil and cause it to bend, thereby reducing the possibility of cracking or stretching the anti-corrosion film on the copper foil when improving the wrinkles on the copper foil, thereby causing defects in the anti-corrosion film on a large area of the copper foil.

[0025] In order to make the contact head assembly 33 always contact with the lower surface of the copper foil when moving, a negative pressure adsorption method is adopted. Figure 3-Figure 5 The contact head assembly 33 includes a self-balancing base 331, a sealing box 332 and an exhaust hose 333. The self-balancing base 331 is fixed to the top of the telescopic rod 32, the sealing box 332 is installed on the top of the self-balancing base 331, and a plurality of air holes are opened on the top of the sealing box 332. The exhaust hose 333 is connected to the sealing box 332.

[0026] During use, one end of the exhaust hose 333 is connected to the gas pipeline to continuously extract the air inside the sealing box 332. The air outside the sealing box 332 enters the sealing box 332 from the air holes due to the pressure difference between the inside and outside of the sealing box 332. The copper foil is adsorbed on the upper surface of the sealing box 332 due to the negative pressure, so that the sealing box 332 is connected to the copper foil. The downward pressure component 34 pushes the two telescopic rods 32 to move gradually away, driving the sealing box 332 to move. Since the sealing box 332 is adsorbed on the copper foil, the negative pressure is used to make the sealing box 332 always stick to the lower surface of the copper foil when moving, so as to achieve the purpose of stretching the copper foil from one place to both sides along the direction of the copper foil, so as to smooth the folds of the copper foil.

[0027] In order to ensure that the contact head assembly 33 can always contact the copper foil when rotating, refer to Figure 4 The telescopic rod 32 includes a swing block 321 and an I-shaped block 322. The swing block 321 is rotatably connected to the support frame 31. A slide groove is provided on the top of the swing block 321, and the I-shaped block 322 extends into the inside of the slide groove.

[0028] When in use, in the initial state, the spring 35 pushes the two telescopic rods 32 together. At this time, the two telescopic rods 32 are close to being perpendicular to the copper foil. The I-shaped block 322 slides along the swing block 321 and gradually approaches the support frame 31. The overall length of the telescopic rod 32 is the shortest. When the downward pressing assembly 34 pushes the two telescopic rods 32 to rotate and gradually move away, the telescopic rod 32 drives the contact head assembly 33 to move along the copper foil and gradually move away from the support frame 31. Since the contact head assembly 33 is adsorbed on the lower surface of the copper foil, it continuously pulls the I-shaped block 322 away from the swing block 321 during the rotation process, so that the overall length of the telescopic rod 32 increases. During the movement, the contact head assembly 33 drives the telescopic rod 32 to repeatedly extend and shorten, so that the contact head assembly 33 can be attached to the copper foil when it moves to different angles.

[0029] Example 2 When the copper foil moves in the horizontal direction, in order to make the contact head assembly 33 always face the copper foil during the rotation process, so as to facilitate the adsorption of the copper foil and the movement along the copper foil, refer to Figures 1-4 The self-balancing base 331 includes an outer frame 3311, a round rod 3312, a sleeve 3313 and a counterweight 3314. The outer frame 3311 is fixedly connected to the top of the telescopic rod 32, the round rod 3312 is installed inside the outer frame 3311, the sleeve 3313 is sleeved on the outside of the round rod 3312, the counterweight 3314 is installed at the bottom of the sleeve 3313, and the sealing box 332 is installed at the top of the sleeve 3313.

[0030] During use, when the copper foil moving path is in the same horizontal plane, the pressing assembly 34 pushes the two telescopic rods 32 to rotate gradually away from each other, thereby driving the two contact head assemblies 33 to rotate, the angles of the sleeve 3313 and the counterweight block 3314 change, the height of the counterweight block 3314 increases, and then the counterweight block 3314 moves to the lowest point under the action of its own gravity, driving the sleeve 3313 and the sealing box 332 to rotate until the counterweight block 3314 rotates to the lowest point and the sealing box 332 rotates to the highest point, so that the sealing box 332 is maintained at the highest point facing the copper foil. When the copper foil moving path is in the same horizontal plane, the contact head assembly 33 can be adjusted to always face the copper foil when the contact head assembly 33 rotates to stretch the copper foil, so that the copper foil can be adsorbed and then moved along the copper foil to produce a stretching effect on the copper foil.

[0031] Example 3 In order to control the two contact head assemblies 33 to gradually move away from each other, and then pull the copper foil to both ends to make the wrinkles of the copper foil flat, refer to Figures 1-6On the basis of Example 1, the pressing assembly 34 includes a horizontal plate 341, a motor 342, a threaded rod 343 and a contact frame 344. The horizontal plate 341 is fixedly connected to the support frame 31, the threaded rod 343 is installed at the bottom of the horizontal plate 341, the motor 342 is installed at the top of the horizontal plate 341, the motor 342 is connected to the threaded rod 343 for transmission, the threaded rod 343 passes through the contact frame 344, the contact frame 344 includes an arc plate 3441, a C-shaped plate 3442 and an arc block 3443, the threaded rod 343 passes through the arc plate 3441, the two C-shaped plates 3442 are respectively installed on both sides of the arc plate 3441, and the arc blocks 3443 are installed at both ends of the C-shaped plate 3442.

[0032] When in use, the motor 342 drives the threaded rod 1 343 to rotate, thereby raising the contact frame 344 to the highest point, and the spring 35 pushes the telescopic rod 32 and the contact head assembly 33 to rotate gradually closer until the inner side of the telescopic rod 32 is blocked by the contact frame 344, completing the process of moving the two contact head assemblies 33 from the farthest distance to gradually closer. When it is necessary to push the two contact head assemblies 33 to rotate gradually away, the motor 342 drives the threaded rod 1 343 to rotate in the opposite direction, thereby driving the contact frame 344 to descend, and the contact frame 344 gradually approaches the area between the rotating shafts of the support frame 31. , so that the area between the rotating shafts of the support frame 31 is expanded after being limited by the contact frame 344, and then the two drive the contact head assemblies 33 away. The gap in the middle of the C-shaped plate 3442 is used for the exhaust hose 333 to pass through, and at the same time, the exhaust hose 333 is limited, which makes it convenient to adjust the positions of the two contact head assemblies 33, so that the two contact head assemblies 33 gradually move away from each other and pull the copper foil to both ends. At the same time, an installation path for the exhaust hose 333 is reserved, which can limit the exhaust hose 333 and reduce the possibility of squeezing the exhaust hose 333 when the telescopic rod 32 and the contact head assembly 33 rotate.

[0033] Example 4 Since the copper foil is pulled from the top of one roller to the bottom of the next roller, the copper foil is partially tilted when being pulled. In order to make the contact head assembly 33 face the horizontal or tilted copper foil, refer to Figure 1-Figure 7 On the basis of Example 1, a bottom frame 4 is fixedly connected to the top of the copper foil coating machine body 1, a support frame 31 is installed inside the bottom frame 4, the support frame 31 is rotatably connected to the bottom frame 4, and a threaded rod 2 5 extending into the interior thereof is provided on one side of the bottom frame 4, and a knob 6 is installed at one end of the threaded rod 2 5.

[0034] When in use, the support frame 31 is rotated along the bottom frame 4 until the support frame 31 and the contact head assembly 33 are facing the copper foil, and then the knob 6 is turned. The knob 6 drives the threaded rod 2 5 to rotate until the threaded rod 2 5 squeezes the support frame 31, fixing the support frame 31 to the bottom frame 4. The direction of the support frame 31 and the contact head assembly 33 can be adjusted as needed, so that the contact head assembly 33 can be facing the copper foil in both the horizontal section and the inclined section of the copper foil.

[0035] In order to facilitate the wiring of the exhaust hose 333 and enable the contact head assembly 33 to flexibly turn, refer to Figure 3 and Figure 7 Channels are provided on both sides of the support frame 31, and the exhaust hose 333 is movable through the channel. The cross-section of the lower half of the outer frame 3311 is a semicircle, and the bottom of the sealing box 332 is an arc surface 7 with the same axis as the outer frame 3311. The diameter of the arc surface 7 is larger than the maximum diameter of the outer frame 3311.

[0036] When in use, the arc surface 7 directly exceeds the maximum diameter of the outer frame 3311 to ensure that the sealing box 332 will not be blocked by the outer frame 3311 when rotating, so that the sealing box 332 can be flexibly rotated to different angles. After the exhaust hose 333 is connected to the sealing box 332, the other end first passes through the C-shaped plate 3442, and then passes through the channel on the support frame 31, and finally connects to the gas channel to complete the wiring process of the exhaust hose 333.
