Technical Field

[0001] The utility model relates to the technical field of thin film electroplating, and more specifically to a conductive clip plating stripping device, electroplating equipment and a plated film. Background Art

[0002] Coating refers to the process of forming a layer of material on a film. Currently, electroplating is the most common method of coating. The conductive film is first unwound from the unwinding roller, and then clamped by the conductive clamp to enter the electroplating area for electroplating. After the electroplating is completed, the conductive film is rewound by the reel.

[0003] However, in the current coating method, after the conductive clip is coated with the coating, the conductive clip is also coated with metal, which affects the clamping effect of the conductive clip on the conductive film and affects the electroplating effect.

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

[0005] In order to solve or alleviate the problem that in the current coating method, after the conductive clip is coated with metal, the conductive clip is also coated with metal, which affects the clamping effect of the conductive clip on the conductive film and affects the electroplating effect, the utility model provides a conductive clip coating stripping device, electroplating equipment and coating.

[0011] In the above-mentioned conductive clip plating stripping device, the length of the stripping tank is smaller than the length of the water washing and soaking tank.

[0012] A plating device comprises a pay-off roller for releasing a conductive film, a plating tank for depositing a coating on the conductive film, a conductive clamp for pulling the conductive film to move in the plating tank, and a winding roller for winding up the conductive film after electroplating, wherein a first deplating zone and a second deplating zone are respectively arranged on both sides of the plating tank, and the first deplating zone and the second deplating zone are both provided with the above-mentioned conductive clamp coating stripping device.

[0025] Embodiment 1

[0026] like Figure 1 As shown, a conductive clip coating stripping device described in one embodiment of the utility model is provided with a stripping tank 1 and a plurality of water washing tanks in sequence along the moving direction of the conductive clip. The direction of the arrow in the figure is the moving direction of the conductive clip. The stripping tank 1 is provided with a stripping liquid for soaking the conductive clip, and the water washing tank is provided with a cleaning liquid for cleaning the stripping liquid on the conductive clip. A liquid removal tank for removing residual liquid on the conductive clip is respectively provided after the stripping tank 1 and each water washing tank.

[0027] In this embodiment, the conductive clip enters from the entrance of the stripping tank 1 and is completely soaked by the stripping liquid. The stripping liquid is an acidic substance that can react with the plating on the conductive clip to strip it from the conductive clip. After passing through the stripping liquid, the conductive clip enters the liquid removal tank behind the stripping tank 1, and the function of the liquid removal tank is to remove the residual stripping liquid on the conductive clip.

[0028] After passing through the de-liquidation tank, the conductive clip enters the first water washing tank. In this water washing tank, the cleaning liquid washes away the stripping liquid on the conductive clip. After the conductive clip is cleaned in the first water washing tank, it enters the de-liquidation tank after the first water washing tank. The function of this de-liquidation tank is to remove the cleaning liquid in the first water washing tank remaining on the conductive clip.

[0029] The conductive clip continues to move forward, passing through other water washing tanks and liquid removal tanks in turn. The function of the water washing tank is to remove the stripping liquid that was not completely removed in the previous water washing tank. After each water washing tank, there is a liquid removal tank. The function of the liquid removal tank is to remove the residual liquid on the conductive clip to prevent the stripping liquid and the cleaning liquid from mixing.

[0030] In this embodiment, by setting up a liquid removal tank, the cross-liquid of the stripping liquid and the cleaning liquid is effectively prevented, and the efficiency and effect of the cleaning process are improved. By setting up multiple water washing tanks, it is ensured that there is no residual stripping liquid on the conductive clip, and the damage of the stripping liquid to the conductive clip and the conductive film 12 is avoided. The plating layer (such as copper, gold, nickel, silver, etc.) on the conductive clip is effectively removed by the acidic stripping liquid, ensuring the conductive performance and subsequent use of the conductive clip.

[0031] like Figure 1 As shown, in a preferred embodiment, along the moving direction of the conductive clip, the water washing tank includes a water washing immersion tank 2 and a water washing spray tank 3. A first deliquency tank 4 is arranged after the stripping tank 1, a second deliquency tank 5 is arranged after the water washing immersion tank 2, and a third deliquency tank 6 is arranged after the water washing spray tank 3. The first deliquency tank 4, the second deliquency tank 5 and the third deliquency tank 6 are respectively provided with a first air-drying part, a second air-drying part and a third air-drying part. The air volume of the first air-drying part, the second air-drying part and the third air-drying part increases successively, so that the residual liquid is completely blown away before the last conductive clip enters the electroplating tank 8. The first air-drying part, the second air-drying part and the third air-drying part are blow pipes, which are connected to the air source through pipelines, and valves for adjusting the air volume are arranged on the pipelines.

[0032] In this embodiment, the conductive clip enters from the stripping tank 1, and after being infiltrated by the stripping liquid, the coating is stripped. After the conductive clip leaves the stripping tank 1, it enters the first deliquescence tank 4. The first deliquescence tank 4 uses the first air-drying component to blow air to remove the residual stripping liquid on the conductive clip. After the conductive clip leaves the first deliquescence tank 4, it enters the first water-washing soaking tank 2, in which the conductive clip is immersed in the cleaning liquid to further remove the stripping liquid. After the conductive clip leaves the water-washing soaking tank 2, it enters the second deliquescence tank 5, and the second deliquescence tank 5 uses the second air-drying component to blow air to remove the residual cleaning liquid on the conductive clip. After the conductive clip leaves the second deliquescence tank 5, it enters the water-washing spray tank 3, in which the cleaning liquid rinses the conductive clip in a spraying manner. After the conductive clip leaves the water-washing spray tank 3, it enters the third deliquescence tank 6. The third deliquescence tank 6 uses the third air-drying component to blow air to remove the residual cleaning liquid on the conductive clip.

[0033] This embodiment more effectively removes the stripping liquid and cleaning liquid on the conductive clip by means of water washing, soaking and spraying, thereby improving the cleaning effect. The provision of the first, second and third liquid removal tanks 6 ensures that there is no residual liquid on the conductive clip, further improving the cleaning effect. The air volume of the first air-drying part, the second air-drying part and the third air-drying part increases successively, which can more thoroughly blow away the residual liquid on the conductive clip, thereby avoiding the influence of the liquid on the subsequent electroplating process. The blow pipe is connected to the air source through a pipeline, and a valve for adjusting the air volume is provided on the pipeline, so that the air volume can be adjusted according to actual needs, thereby increasing the flexibility and adaptability of the device.

[0034] In the present embodiment, the blow pipe can be designed to have a plurality of small holes, which are evenly distributed along the length direction of the blow pipe. When the gas passes through the blow pipe, the gas is blown out from the small holes to form a uniform wind force, which can ensure that all parts on the conductive clip can be blown by the uniform wind force, thereby improving the drying effect. In addition, the air-drying part can use a small fan to generate wind force. The outlet of the fan is designed to face the direction of the conductive clip so that the wind force can be directly blown onto the conductive clip. The air volume of the fan can be controlled by adjusting the speed of the fan to adapt to different drying needs. Alternatively, the air-drying part can use an air jet nozzle, which has a narrow nozzle, and when the gas passes through the nozzle, a high-speed air flow is formed. The high-speed air flow can generate a greater blowing force on the residual liquid on the conductive clip, thereby more effectively blowing off the residual liquid. In order to better control the blowing force of the air flow, an air flow regulating valve can be set to adjust the size of the air flow as needed. The specific selection is considered according to the actual production environment and conditions to ensure the best blowing effect and production efficiency.

[0035] like Figure 1 As shown, in a preferred embodiment, the length of the stripping tank 1 is less than the length of the water-washing and soaking tank 2. Since the moving speed of the conductive clip is uniform, the processing time is controlled by controlling the length of the stripping tank 1 and the water-washing and soaking tank 2. Since the length of the water-washing and soaking tank 2 is relatively long, the conductive clip can be fully soaked in the cleaning liquid in the water-washing and soaking tank 2, thereby further removing the stripping liquid and other residues, so that the acidic stripping liquid on the conductive clip is washed clean in the water-washing and soaking tank 2. In addition, the length of the stripping tank 1 is relatively short, which prevents the conductive clip from being soaked in the stripping liquid for too long, prevents the acidic stripping liquid from damaging the conductive clip, and ensures the quality and life of the conductive clip.

[0036] Embodiment 2

[0037] like Figure 2As shown, an electroplating device described in one embodiment of the utility model includes a unwinding roller 7 for releasing a conductive film 12, a plating tank 8 for depositing a coating on the conductive film 12, a conductive clamp for pulling the conductive film 12 to move in the plating tank 8, and a winding roller 9 for winding up the conductive film 12 after electroplating, a first deplating zone 10 and a second deplating zone 11 are respectively arranged on both sides of the plating tank 8, and the first deplating zone 10 and the second deplating zone 11 are both provided with the above-mentioned conductive clamp coating stripping device.

[0038] When the present embodiment is working, the conductive film 12 is first unwound from the unwinding roller 7, and enters the electroplating tank 8 for electroplating under the clamping of the conductive clamp. After the conductive film 12 is conducted, it enters the winding roller 9 for winding. The conductive clamp releases the clamping mouth before the conductive film 12 is wound by the winding roller 9, so as to facilitate the winding of the winding roller 9. After the conductive clamp releases the conductive film 12, it enters the deplating area for deplating. After deplating, the conductive clamp continues to clamp the conductive film 12 unwound from the unwinding roller 7 at the unwinding roller 7, and the above-mentioned actions are repeated.

[0039] In this embodiment, by setting the first deplating area 10 and the second deplating area 11, the conductive clips on both sides of the electroplating tank 8 enter the deplating area for deplating after the electroplating is completed, thereby removing the plating layer attached thereto during the previous electroplating process, preventing the plating layer on the conductive clips from affecting subsequent electroplating operations, thereby improving the stability and reliability of the production process and ensuring product quality.

[0040] Embodiment 3

[0041] like Figure 3 As shown, a coating described in one embodiment of the utility model includes a conductive film 12, the conductive film 12 includes a base film and a conductive layer deposited on the upper and lower surfaces of the base film, and the conductive clips in the above-mentioned conductive clip coating stripping device or the conductive clips in the above-mentioned electroplating equipment are clamped on both sides of the conductive film 12, and are used to pull the conductive film 12 to move in the electroplating tank 8 to deposit the coating. From the top view, the conductive film 12 includes two parts, a middle conductive layer 1201 and edge conductive layers 1202 located on both sides of the middle conductive layer 1201, and the edge conductive layers 1202 are used to be clamped by the conductive clips.

[0042] In a preferred embodiment, the conductive strength of the edge conductive layer 1202 is greater than the conductive strength of the middle conductive layer 1201, so that the conductivity of the middle conductive layer 1201 can be stronger, and the coating efficiency can be higher. The edge conductive layer 1202 is clamped by the conductive clamps on both sides and is easily broken, so that the conductivity of the edge conductive layer 1202 becomes weaker and the current of the middle conductive layer 1201 is weakened. In this embodiment, even if the edge conductive layer 1202 is broken, the coating efficiency of the middle conductive layer 1201 can still be guaranteed because the conductive strength of the edge conductive layer 1202 is enhanced and the current of the middle conductive layer 1201 is slightly weakened.

[0043] In a preferred embodiment, the thickness of the two sides of the conductive film 12 is greater than the thickness in the middle, which can improve the strength and durability of the edge conductive layer 1202 so that the edge conductive layer 1202 will not be easily damaged after being clamped by the conductive clamp.

[0044] In a preferred embodiment, the plated layer is a copper layer, which has good electrical conductivity and can improve the electrical conductivity and stability of the plated film.

[0045] 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 in the protection scope of the present invention.
