Description

Technical Field

[0001] This invention relates to the field of thin film electroplating technology, and more specifically, to a thin film electroplating system and electroplating process. Background Technology

[0002] The electroplating process in thin-film electroplating equipment involves a conveyor system that pulls the film along, with conductive clamps holding both sides. A steel belt drives the conductive clamps, thus drawing the film into the electroplating solution for electroplating. The stability of the steel belt's operation is crucial to the electroplating quality of the film; however, existing steel belts still have many problems during operation.

[0003] For example, after the conveyor system has been operating for a period of time, a layer of metal (such as copper, gold, nickel, silver, etc.) may be back-plated onto the conductive clips entering the plating solution, affecting the quality of the film. Currently, the main solution is to install a stripping device on the electroplating equipment to remove the plating layer from the conductive clips. However, existing stripping devices generally only use static liquid immersion to strip the conductive clips, without treating the steel strip. During the operation of the conveyor system, electroplating solution may splash onto the steel strip, causing the plating solution on the steel strip to dry and crystallize, affecting the lifespan of the steel strip.

[0004] The above shortcomings need to be improved. Summary of the Invention

[0005] To address the problem that existing stripping devices typically only use static liquid immersion to strip the conductive clips without treating the steel strip, resulting in electroplating solution splashing onto the steel strip during operation and causing the electroplating solution on the steel strip to dry and crystallize, thus affecting the lifespan of the steel strip, this invention provides a thin-film electroplating system and electroplating process.

[0006] The technical solution of this invention is as follows:

[0007] A thin-film electroplating system includes an unwinding device, a pre-plating device, an electroplating device, a cleaning device, an anti-oxidation device, a drying device, and a rewinding device. The unwinding device releases a thin film, which sequentially passes through the pre-plating device, the electroplating device, the cleaning device, the anti-oxidation device, and the drying device, and is then rewound by the rewinding device. The electroplating device includes a conveying device and a stripping device. The conveying device includes a steel strip and conductive clips disposed on the steel strip. The stripping device is used to clean the steel strip and the conductive clips.

[0008] In the aforementioned thin-film electroplating system, the stripping device includes a stripping tank with multiple partitions dividing it into multiple working sections. Each working section includes an immersion section, a spray section, and a drying section. The immersion section contains a stripping solution for wetting the conductive clips. The spray section is equipped with spray pipes for rinsing the conductive clips and steel strips. The drying section is used to dry the conductive clips.

[0009] Furthermore, the soaking section is equipped with multiple spray pipes with different water outlet directions.

[0010] In the aforementioned thin-film electroplating system, the conveying device is disposed on both sides of the thin film. The conveying device includes a tensioning mechanism, which includes a fixed base and a movable base slidably connected to the fixed base. The movable base is provided with a roller for mounting a steel strip. An adjusting component is connected between the fixed base and the movable base. The adjusting component is used to drive the movable base to slide on the fixed base, thereby changing the horizontal distance between the fixed base and the movable base to tension the steel strip.

[0011] Furthermore, the adjustment assembly includes a mounting base connected to the fixed base. The mounting base is provided with a driving member and a screw, which are connected in a transmission manner. One end of the screw is connected to the movable base. The driving member is used to drive the screw to rotate and change the horizontal distance between the fixed base and the movable base. The movable base is provided with a connecting plate. One end of the screw is connected to a connecting post that passes through the connecting plate. A spring is sleeved on the outside of the connecting post, and both ends of the spring abut against the end of the connecting post and the connecting plate, respectively.

[0012] In the aforementioned thin-film electroplating system, the conveying device includes a speed measuring mechanism, which includes a mounting plate. A movable plate is slidably disposed on the mounting plate, and an encoder is mounted on the movable plate. A speed measuring wheel is disposed on the rotating shaft of the encoder. An elastic element is disposed between the mounting plate and the movable plate to adjust their relative positions. The elastic element is used to keep the outer surface of the speed measuring wheel in contact with the steel belt.

[0013] In the aforementioned thin-film electroplating system, the conveying device includes a conductive device, which comprises two symmetrically arranged mounting frames. A slide rail is provided between the two mounting frames, and a guide module is slidably suspended on the slide rail. Several sets of conductive brushes are arranged on both sides of the guide module, with two conductive brushes forming a set. Each set of conductive brushes is rotatably connected to the two mounting frames, and an elastic traction member is provided between each set of conductive brushes. The elastic traction member is used to pull each set of conductive brushes closer to each other and tightly adhere to the guide module.

[0014] In the aforementioned thin-film electroplating system, the conductive clamp includes a conductive lower clamp, an upper clamp guide plate on the conductive lower clamp, a conductive upper clamp slidably connected to the upper clamp guide plate, a crossbar on the upper clamp guide plate, a first guide member at the end of the crossbar, a push rod slidably connected to the crossbar, a second guide member cooperating with the first guide member at the first end of the push rod, a guide rail for changing the center distance between the first guide member and the second conductive member, and a lifting inclined block at the second end of the conductive upper clamp near the push rod, the push rod being used to push the lifting inclined block to open the conductive upper clamp and the conductive lower clamp.

[0015] In the aforementioned thin-film electroplating system, the conductive clamp includes a conductive lower clamp and a conductive upper clamp slidably connected to the conductive lower clamp. The conductive upper clamp is provided with a movable guide, and the conductive lower clamp is provided with a fixed guide. A guide rail is provided between the movable guide and the fixed guide. The distance between the fixed guide and the movable guide is changed by the change in the thickness of the guide rail, which is used to drive the conductive upper clamp to slide up and down relative to the conductive lower clamp to realize the opening and closing of the conductive clamp.

[0016] A thin-film electroplating process, using the aforementioned thin-film electroplating system, includes the following steps:

[0017] S1. Unwinding: The roll of film to be coated is initially placed on the unwinding equipment and released by the unwinding equipment;

[0018] S2, Pre-plating: The film to be plated released by the unwinding equipment first enters the pre-plating equipment, which performs pre-plating treatment on the film to be plated, pre-plating a layer on the surface of the film to be plated.

[0019] S3, Electroplating: The pre-plated film enters the electroplating equipment. In the electroplating equipment, the conductive clamps clamp both sides of the film. Then, the steel belt drives the conductive clamps to move. The conductive clamps carry the film in the electroplating equipment and supply cathode power to the film. During the movement, an electroplating layer is deposited on the surface of the film. When the film moves to the end of the electroplating equipment, it separates from the conductive clamps. The stripping assembly cleans the steel belt and the conductive clamps.

[0020] S4. Cleaning: The electroplated film enters the cleaning equipment, which sprays, soaks, and sprays the top and bottom surfaces of the film to remove the residual plating solution on both surfaces.

[0021] S5, Antioxidant: After cleaning, the film enters the antioxidant equipment, where an antioxidant film is deposited on the electroplated layer of the film.

[0022] S6. Drying: The film after the antioxidant treatment enters the drying equipment to remove the residual antioxidant liquid on the film surface;

[0023] S7. Winding: The dried film enters the winding equipment, which winds the film into a roll.

[0024] According to the above-described solution, the beneficial effect of this invention is that by setting up a stripping device, the plating layer on the conductive clip and the electroplating solution crystals on the steel strip are cleaned, ensuring that the conductive clip and the steel strip can work stably and normally, thereby enabling the conveying device to stably pull the film in the electroplating equipment and stably supply cathode power to the film, so that a conductive layer is plated on its surface.

[0041] Example 1

[0042] like Figure 1 and Figure 2As shown, a thin-film electroplating system according to one embodiment of the present invention includes an unwinding device 1, a pre-plating device 2, an electroplating device 3, a cleaning device 4, an anti-oxidation device 5, a drying device 6, and a winding device 7. The unwinding device 1 releases a thin film 8, which sequentially passes through the pre-plating device 2, the electroplating device 3, the cleaning device 4, the anti-oxidation device 5, and the drying device 6, and is then wound up by the winding device 7. The electroplating device 3 includes a conveying device 301 and a stripping device 338. The conveying device 301 includes a steel strip 302 and a conductive clip 303 disposed on the steel strip 302. The stripping device 338 is used to clean the steel strip 302 and the conductive clip 303.

[0043] In this embodiment, the film 8 to be plated is released from the unwinding device 1 and passes sequentially through the pre-plating device 2, the electroplating device 3, the cleaning device 4, the anti-oxidation device 5, and the drying device 6. The winding device finally winds up the electroplated film 8. The film 8 undergoes pre-plating treatment in the pre-plating device 2, where a coating layer is pre-plated on the surface of the film 8 to improve its surface properties and facilitate electroplating. After pre-plating, the film 8 enters the electroplating device 3, where it undergoes electroplating treatment, i.e., a conductive layer is deposited on its surface. The film 8 is pulled and moved in the electroplating device 3 by the conveying device 301, which also supplies cathode power to the film 8. During the electroplating process, the conductive clip 303, which extends into the electroplating solution, is also plated with a layer of metal, affecting its conductivity. In addition, the electroplating solution splashes onto the steel strip 302, and the dried electroplating solution crystallizes on the steel strip 302, affecting its lifespan. After passing through the stripping device 338, the conductive clip 303 and the steel strip 302 have their plating removed, and the dried crystals removed, allowing the conveying device 301 to operate normally. After electroplating, the film 8 enters the cleaning device 4, where residual plating solution is removed from the surface of the film 8 to reduce its corrosive effect. After cleaning, the film 8 enters the anti-oxidation device 5, where an anti-oxidation film is deposited on its surface to protect both the plating layer and the film 8. After the anti-oxidation film is applied, the film 8 enters the drying device 6 to dry the anti-oxidation solution on its surface. Finally, the dried film 8 is wound onto the winding device 7 for rewinding.

[0044] In this embodiment, by setting up a stripping device 338, the plating layer on the conductive clip 303 and the electroplating solution crystals on the steel strip 302 are cleaned to ensure that the conductive clip 303 and the steel strip 302 can work stably and normally, so that the conveying device 301 can stably pull the film 8 to move in the electroplating equipment 3 and stably supply cathode power to the film 8, so that a conductive layer is plated on its surface.

[0045] like Figure 6As shown, in a preferred embodiment, the stripping device 338 includes a stripping groove 339, in which a plurality of partitions 340 are provided, dividing the stripping groove 339 into a plurality of working sections. The working sections include an immersion section 341, a spraying section 342, and a drying section 343. The immersion section 341 is filled with stripping liquid for wetting the conductive clip 303, and is provided with a plurality of spray pipes with different water outlet directions. The spraying section 342 is provided with spray pipes 344, which are used to rinse the conductive clip 303 and the steel strip 302. The drying section 343 is used to dry the conductive clip 303.

[0046] In this embodiment, multiple partitions 340 within the stripping groove 339 divide it into multiple working sections, each with a different function. This precise division makes the stripping process of the conductive clip 303 and steel strip 302 more efficient. The stripping groove 339 includes an immersion section 341, a spraying section 342, and a drying section 343, which can thoroughly clean the conductive clip 303 and steel strip 302 to ensure that the conductive clip 303 maintains good conductivity and that the steel strip 302 can operate normally.

[0047] During use, the conductive clamp 303, driven by the steel belt 302, sequentially passes through the soaking section 341, the spraying section 342, and the drying section 343 in the working section. The soaking section 341 is filled with a stripping solution, which effectively wets the conductive clamp 303. This step typically requires a certain amount of time. By setting multiple soaking sections 341, the conductive clamp 303 can be soaked for a sufficiently long time to ensure that the stripping solution fully contacts the conductive clamp 303 and slowly dissolves the metal deposited on it. Furthermore, in this embodiment, the soaking section 341 is equipped with multiple spray pipes with nozzles facing different directions. The spray pipes are connected to water inlet pipes, and multiple nozzles are opened on the side walls of the spray pipes. The spray pipes can be rotated to adjust the direction of the nozzles, facilitating adjustments according to production needs. Cleaning fluid is supplied to the spray pipes through the inlet pipes. Multiple openings on the sidewalls of the spray pipes enhance the spraying effect, allowing the stripping fluid to thoroughly rinse the multiple conductive clips 303, effectively removing deposits from their surfaces and ensuring the cleanliness of the contact surfaces between the conductive clips 303 and the film 8. Furthermore, the different directions of the spray nozzles in the multiple spray pipes create a liquid circulation flow within the stripping tank 339, promoting liquid mixing and distribution. This results in a more even distribution of the stripping fluid throughout the tank, improving cleaning efficiency. The spray pipes 344 in the spray section 342 spray cleaning fluid onto the conductive clips 303 and the steel strip 302, rinsing away the stripping fluid and residual metal substances. Finally, the drying section 343 air-dries the conductive clips 303 and the steel strip 302, removing any residual liquid and ensuring they remain clean and dry before re-operation, preventing corrosion from liquid residue.

[0048] In this embodiment, by setting multiple different working sections, the deposited metal on the conductive clamp 303 in the electroplating equipment 3 can be effectively removed, and the electroplating solution on the steel strip 302 can be prevented from drying and crystallizing. This ensures the normal operation of the conductive clamp 303 and the steel strip 302, thereby maintaining the electroplating equipment 3 in a good working condition and ensuring its long-term stable operation. By setting multiple oriented spray pipes, the spray nozzles on the multiple spray pipes have different orientations, and the spray pipes can be rotated to adjust the orientation of the spray nozzles. This facilitates adjustment according to production needs, promotes liquid mixing and distribution, and improves cleaning efficiency.

[0049] like Figures 3 to 5As shown, in a preferred embodiment, the conveying device 301 is disposed on both sides of the film 8. The conveying device 301 includes a tensioning mechanism 315, which includes a fixed seat 316. A movable seat 317 is slidably connected to the fixed seat 316. A roller 318 for supporting the steel belt 302 is disposed on the movable seat 317. An adjusting component 319 is connected between the fixed seat 316 and the movable seat 317. The adjusting component 319 is used to drive the movable seat 317 to slide on the fixed seat 316, thereby changing the horizontal distance between the fixed seat 316 and the movable seat 317 to tension the steel belt 302.

[0050] The adjusting assembly 319 includes a mounting base 320 connected to a fixed base 316. A driving member 321 and a screw 322 are provided on the mounting base 320. The driving member 321 and the screw 322 are connected by transmission. One end of the screw 322 is connected to a movable base 317. The driving member 321 is used to drive the screw 322 to rotate and change the horizontal distance between the fixed base 316 and the movable base 317. A connecting plate 323 is provided on the movable base 317. One end of the screw 322 is connected to a connecting post 324 that passes through the connecting plate 323. A spring 325 is sleeved on the outside of the connecting post 324. The two ends of the spring 325 abut against the ends of the connecting post 324 and the connecting plate 323, respectively.

[0051] In this embodiment, the steel strip 302 is first fitted onto two rollers 318. Then, the adjusting component 319 drives the movable seat 317 to slide on the fixed seat 316, changing the horizontal distance between the fixed seat 316 and the movable seat 317. One roller 318 is fixed, while the other roller 318 slides with the movable seat 317. The center distance between the two rollers 318 changes, and the tension of the steel strip 302 also changes accordingly, thereby adjusting the tension of the steel strip 302. When the steel strip 302 reaches the required tension, the adjusting component 319 stops driving the movable seat 317 to slide, thus maintaining the tension of the steel strip 302 and enabling it to run stably, steadily driving the film 8 to move within the electroplating equipment 3.

[0052] Specifically, when adjusting the tension of the steel strip 302, the drive component 321 first rotates, and then the drive component 321 drives the screw 322 to rotate through the transmission device. The screw 322 rotates on the mounting base 320, and at the same time, the screw 322 moves axially. The screw 322 drives the movable seat 317 to slide on the fixed seat 316, thereby changing the horizontal distance between the fixed seat 316 and the movable seat 317, and thus adjusting the tension of the steel strip 302.

[0053] Specifically, technicians manually drive the drive component 321 to rotate. The drive component 321 and the screw 322 are connected by a helical gear set, causing the screw 322 to rotate. This changes the horizontal distance between the fixed seat 316 and the movable seat 317, thereby altering the tension of the steel belt 302. During operation, the tension of the steel belt 302 continuously changes. The spring 325, with its excellent elasticity, can extend and retract in response to these changes in tension, thus automatically adjusting the tension of the steel belt 302 in real time. This prevents over-tensioning or over-slackness, protecting the steel belt 302, ensuring its service life, and improving the operational stability of the equipment.

[0054] In practical applications, the drive component 321 can also be a motor. A motor can also enable automated and remote control, improving the convenience and precision of operation. Using a motor as the drive component further enhances the stability and reliability of the equipment.

[0055] like Figure 7 As shown, in a preferred embodiment, the conveying device 301 includes a speed measuring mechanism 326, which includes a mounting plate 327. A movable plate 328 is slidably disposed on the mounting plate 327. An encoder 329 is mounted on the movable plate 328. A speed measuring wheel 330 is disposed on the rotating shaft of the encoder 329. An elastic element 331 is disposed between the mounting plate 327 and the movable plate 328 to adjust their relative positions. The elastic element 331 is used to keep the outer surface of the speed measuring wheel 330 in contact with the steel belt 302.

[0056] In this embodiment, when the steel belt 302 is running, the outer surface of the speed measuring wheel 330 contacts the surface of the steel belt 302. Under the action of friction, the speed measuring wheel 330 rotates along with the steel belt 302. The speed measuring wheel 330 then drives the shaft of the encoder 329 to rotate. The encoder 329 converts the rotation speed signal into an electrical signal, and then the data processing unit calculates the speed of the steel belt 302. The movable plate 328 can slide on the mounting plate 327 according to the position of the steel belt 302, so that there is a stable contact between the speed measuring wheel 330 and the steel belt 302. This ensures that the friction between the speed measuring wheel 330 and the steel belt 302 ensures that their linear velocities are the same, thus ensuring the accuracy of the speed measurement. During operation, the tension of the steel belt 302 changes constantly. This change in tension weakens or strengthens the contact force between the speed measuring wheel 330 and the steel belt 302. The elastic element 331 ensures close contact between the speed measuring wheel 330 and the steel belt 302. The elastic element 331 adjusts the relative position of the movable plate 328 and the mounting plate 327. When the tension of the steel belt 302 decreases, the steel belt 302 becomes looser, and the elastic element 331 drives the movable plate 328 to slide on the mounting plate 327. The movable plate 328 and the mounting plate 327 move away from each other, making the speed measuring wheel 330 close to the steel belt 302. When the tension of the steel belt 302 increases, the steel belt 302 becomes taut, and the steel belt 302 presses against the speed measuring wheel 330. The speed measuring wheel 330 pushes the movable plate 328 to slide on the mounting plate 327, causing the elastic element 331 to return to its initial state. The elastic element 331 automatically adjusts the distance and contact force between the speed measuring wheel 330 and the steel belt 302 to ensure that the speed measuring mechanism 326 can always accurately measure the speed of the steel belt 302, thereby improving the measurement accuracy.

[0057] In this embodiment, the steel belt 302 transmission speed measuring mechanism 326 is equipped with an elastic element 331 and a movable plate 328. Under the action of the elastic element 331, the movable plate 328 can adapt to the change in the tension of the steel belt 302, maintain close contact between the speed measuring wheel 330 and the steel belt 302, accurately measure the transmission speed, facilitate monitoring and control of the electroplating process, and ensure the electroplating quality.

[0058] like Figure 8 and Figure 9 As shown, in a preferred embodiment, the conveying device 301 includes a conductive device 332, which includes two symmetrically arranged mounting brackets 333. A slide rail 334 is provided between the two mounting brackets 333. A guide module 335 is slidably suspended on the slide rail 334. Several sets of conductive brushes 336 are arranged on both sides of the guide module 335. Two conductive brushes 336 form a group. Each group of conductive brushes 336 is rotatably connected to the two mounting brackets 333. An elastic traction member 337 is provided between each group of conductive brushes 336. The elastic traction member 337 is used to pull each group of conductive brushes 336 closer to each other and tightly adhere to the guide module 335.

[0059] In this embodiment, during operation, the guide module 335 slides along the slide rail 334 on two mounting plates 327. The mounting plates 327 support the guide module 335 and guide its direction via the slide rail 334. During the sliding process, the conductive brushes 336 on the mounting plates 327 maintain contact with the sides of the guide module 335. The conductive brushes 336 are connected to a power source, thereby directing current to the guide module 335, which then directs it to the film to be plated 8, allowing electroplating to be performed on the film 8. Each group of two conductive brushes 336 contacts both sides of the guide module 335, ensuring the stability of the electrical connection between the guide module 335 and the power source. Furthermore, each group of conductive brushes 336 is connected by an elastic traction member 337, causing the two conductive brushes in each group to tend to move closer together, thus stably clamping each group of two conductive brushes 336 on both sides of the guide module 335, ensuring the stability of the electrical connection.

[0060] In this embodiment, by setting an elastic traction member 337 between each group of conductive brushes 336, one elastic traction member 337 can pull two conductive brushes 336 closer to each other. On the one hand, this ensures stable contact between the conductive brushes 336 and the guide module 335, maintaining good electrical connection, thereby ensuring the electroplating quality of the thin film 8. On the other hand, the structure is relatively simple, has good structural stability, and is easy to install and maintain.

[0061] like Figure 10 As shown, in a preferred embodiment, the conductive clamp 303 includes a conductive lower clamp 304, an upper clamp guide plate 306 is provided on the conductive lower clamp 304, a conductive upper clamp 305 is slidably connected to the upper clamp guide plate 306, a crossbar 307 is provided on the upper clamp guide plate 306, a first guide member 308 is provided at the end of the crossbar 307, a push rod 309 is horizontally slidably connected to the crossbar 307, a second guide member 310 that cooperates with the first guide member 308 is provided at the first end of the push rod 309, a guide rail 311 that changes the center distance between the first guide member 308 and the second conductor member is provided, and a lifting inclined block 312 is provided at the second end of the conductive upper clamp 305 near the push rod 309, the push rod 309 is used to push the lifting inclined block 312 to open the conductive upper clamp 305 and the conductive lower clamp 304.

[0062] In this embodiment, the conductive clamp 303 is installed on the steel strip 302. When the conductive clamp 303 needs to open, the first guide 308 and the second guide 310 enter the guide rail 311. As the width of the guide rail 311 gradually increases, the center distance between the first guide 308 and the second guide 310 increases, thereby pushing the push rod 309 to slide horizontally. The second end of the push rod 309 pushes the lifting inclined block 312 to rise, which drives the upper conductive clamp 305 to rise, so that the clamping part between the upper conductive clamp 305 and the lower conductive clamp 304 opens. As the steel belt 302 moves, the film 8 to be electroplated is located between the clamping parts of the conductive upper clamp 305 and the conductive lower clamp 304. At this time, the width of the guide rail 311 gradually decreases. Under the action of gravity of the conductive upper clamp 305, the clamping parts between the conductive upper clamp 305 and the conductive lower clamp 304 close, clamping the film 8 to be electroplated. At this time, the first guide member 308 and the second guide member 310 disengage from the guide rail 311, and the steel belt 302 drives the film 8 to be plated to move in the electroplating equipment 3 to complete the electroplating. After the electroplating is completed, the first guide member 308 and the second guide member 310 enter the guide rail 311 at the end of the electroplating equipment 3. As the width of the guide rail 311 gradually increases, the center distance between the first guide member 308 and the second guide member 310 increases, the clamping parts between the conductive upper clamp 305 and the conductive lower clamp 304 open, release the film 8, and separate from the film 8.

[0063] In this embodiment, the horizontal movement of the push rod 309 drives the vertical movement of the conductive upper clamp 305. The first guide member 308 moves horizontally along the bottom of the guide rail 311, and the second guide member 310 pushes the conductive upper clamp 305 along the top of the guide rail 311. The conductive upper clamp 305 slides on the upper clamp guide plate 306. Since the first guide member 308 and the conductive lower clamp 304 are integrated, and the upper clamp guide plate 306 and the conductive lower clamp 304 are integrated, the forces between the first guide member 308, the second guide member 310, and the guide rail 311 are balanced, and no torque is generated on the steel strip 302. This makes it difficult for the steel strip 302 to tilt, ensuring that the tension of the steel strip 302 is relatively uniform across the entire width, making it less prone to damage, ensuring the operational stability and service life of the steel strip 302, thereby ensuring the stability of the electroplating process of the thin film 8 and ensuring the electroplating quality.

[0064] Example 2

[0065] like Figure 11As shown, the difference between this embodiment and Embodiment 1 is that the conductive clamp 303 includes a conductive lower clamp 304 and a conductive upper clamp 305 slidably connected to the conductive lower clamp 304. The conductive upper clamp 305 is provided with a movable guide 313, and the conductive lower clamp 304 is provided with a fixed guide 314. A guide rail 311 is provided between the movable guide 313 and the fixed guide 314. The distance between the fixed guide 314 and the movable guide 313 is changed by the change in the thickness of the guide rail 311, which is used to drive the conductive upper clamp 305 to slide up and down relative to the conductive lower clamp 304 to realize the opening and closing of the conductive clamp 303.

[0066] In this embodiment, during operation, the steel strip 302 rotates, causing the conductive clamp 303 to move. When the conductive clamp 303 needs to open, the fixed guide 314 and the movable guide 313 slide into the guide rail 311. As the thickness of the guide rail 311 gradually increases, the center distance between the fixed guide 314 and the movable guide 313 increases. The bottom position of the guide rail 311 remains unchanged, meaning the top height of the guide rail 311 changes. The fixed guide 314 contacts the bottom of the guide rail 311, and its position remains unchanged, always maintaining contact with the bottom of the guide rail 311. The movable guide 313 contacts the top of the guide rail 311. The movable guide 313 rises as the top height of the guide rail 311 increases, causing the upper conductive clamp 305 to rise, thus opening the clamping portion between the upper conductive clamp 305 and the lower conductive clamp 304. As the steel belt 302 moves, the film 8 to be plated is positioned between the upper conductive clamp 305 and the lower conductive clamp 304. Then, the thickness of the guide rail 311 gradually decreases. Under the weight of the upper conductive clamp 305, it slides downwards, closing the clamping area between the upper and lower conductive clamps 305 and clamping the film 8 to be plated. At this point, the fixed guide 314 and the movable guide 313 disengage from the guide rail 311, and the steel belt 302 propels the film 8 through the electroplating equipment 3 to complete the electroplating process. After electroplating, the fixed guide 314 and the movable guide 313 enter the guide rail 311 at the end of the electroplating equipment 3. As the thickness of the guide rail 311 gradually increases, the center distance between the fixed guide 314 and the movable guide 313 increases, causing the clamping area between the upper conductive clamp 305 and the lower conductive clamp 304 to open, releasing the film 8 and separating it from the plate.

[0067] In this embodiment, by setting the fixed guide member 314 to contact the bottom of the guide rail 311, during the process of driving the conductive upper clamp 305 to open through the guide rail 311, sliding friction is generated between the conductive upper clamp 305 and the conductive lower clamp 304. The conductive upper clamp 305 exerts an upward force on the conductive lower clamp 304. Part of the upward force of the conductive lower clamp 304 acts on the steel strip 302 and part acts on the guide rail 311. The guide rail 311 and the steel strip 302 are located on both sides of the conductive lower clamp 304, which makes the action of the conductive upper clamp 305 stable and effectively reduces the force on the steel strip 302. The steel strip 302 is not easy to tilt, ensuring that the tension of the steel strip 302 is relatively uniform across the entire width, making it less prone to damage, ensuring the stability and service life of the steel strip 302, thereby ensuring the stability of the electroplating process of the thin film 8 and ensuring the electroplating quality.

[0068] Example 3

[0069] like Figure 12 As shown, a thin-film electroplating process according to one embodiment of the present invention, using the above-mentioned thin-film electroplating process, includes the following steps:

[0070] S1. Unwinding: The 8 rolls of film to be coated are initially placed on the unwinding device 1 and released through the unwinding device 1;

[0071] S2, Pre-plating: The film to be plated 8 released by the unwinding device 1 first enters the pre-plating device 2, and the pre-plating device 2 performs pre-plating treatment on the film to be plated 8, pre-plating a layer on the surface of the film to be plated 8.

[0072] S3, Electroplating: The pre-plated film 8 enters the electroplating equipment 3. In the electroplating equipment 3, the conductive clamp 303 clamps both sides of the film 8. Then, the steel belt 302 drives the conductive clamp 303 to move. The conductive clamp 303 drives the film 8 to move in the electroplating equipment 3 and supplies cathode power to the film 8. During the movement, an electroplating layer is deposited on the surface of the film 8. When the film 8 moves to the end of the electroplating equipment 3, it separates from the conductive clamp 303. The peeling assembly cleans the steel belt 302 and the conductive clamp 303.

[0073] S4. Cleaning: The electroplated film 8 enters the cleaning equipment 4. The cleaning equipment 4 sprays, soaks, and sprays the upper and lower surfaces of the film 8 to remove the residual plating solution on the upper and lower surfaces of the film 8.

[0074] S5, Antioxidation: The cleaned film 8 enters the antioxidation equipment 5, where an antioxidation film is deposited on the electroplating layer of the film 8.

[0075] S6. Drying: The anti-oxidation treated film 8 enters the drying equipment 6 to remove the residual anti-oxidation liquid on the surface of the film 8;

[0076] S7. Winding: The dried film 8 enters the winding device 7, which winds the film 8 into a roll.

[0077] In this embodiment, by applying the above-mentioned electroplating system, the stability of the steel strip 302 can be improved, thereby ensuring that the film 8 moves stably in the electroplating equipment 3 and ensuring the electroplating quality of the film 8.

[0078] In this process, the unwinding equipment 1, the pre-coating equipment 2, the cleaning equipment 4, the anti-oxidation equipment 5, the drying equipment 6, and the winding equipment 7 support and pull the film 8 through rollers.

[0079] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
