Description

Technical Field

[0001] The invention relates to the technical field of thin film electroplating, and in particular to a horizontal double-sided ultra-thin film electroplating device. Background Art

[0002] PET electroplated ultra-thin film (thickness 4 microns) is often used in lithium battery negative electrodes, FPC (flexible circuit boards) and other fields. The PET electroplated film includes a PET substrate layer, a rough copper layer deposited on the surface of the PET substrate layer by deposition, and an electroplated layer electroplated on the surface of the rough copper layer. The PET substrate layer and the rough copper layer electroplated layer are collectively referred to as the film to be electroplated. The electroplated layer can be electroplated copper / nickel / tin, etc.

[0003] In the final step of producing PET electroplated film - the electroplating process, electroplating equipment is used for electroplating. Traditional electroplating equipment uses multiple transmission rollers to horizontally transfer the film to be plated to the electroplating tank. The electroplating solution immerses the film to be plated for double-sided electroplating. When the film to be plated enters the electroplating tank, the two sides of the film to be plated are clamped by clamps to keep the balance of the film to be plated in the electroplating solution.

[0004] However, traditional electroplating equipment has at least the following problems:

[0005] 1) Using a clamp to clamp the film, because the clamping force of the clamp cannot be guaranteed to be uniform, and the clamps on both sides cannot be guaranteed to be completely synchronized when conveying the film into the electroplating tank, it is easy to cause uneven film tension, thereby affecting the quality of the electroplated film;

[0006] 2) During electroplating, the conductive roller is usually used to contact the substrate for conduction, but the conductive roller is far away from the electroplating area, which can easily cause burn holes on the film surface and consume more energy;

[0007] 3) The electroplating tank is generally fixed on the frame. When the electroplating tank needs to be cleaned after long-term use, it is difficult to disassemble and clean.

[0008] Therefore, in view of the above-mentioned technical problems, it is necessary to provide a new technical solution. Summary of the invention

DETAILED DESCRIPTION

The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present invention, and should not be construed as limiting the present invention. Example

[0030] See also Figures 1 to 4 A horizontal double-sided ultra-thin film electroplating equipment comprises a fixed frame 1 with a feeding roller 6 on one side, an electroplating mechanism 2 is installed on the fixed frame 1, the electroplating mechanism 2 comprises an electroplating tank 21, the electroplating tank 21 is arc-shaped, a pair of electroplating wheels 3 with equal diameters and concentrically arranged are installed in the electroplating tank 21, the two electroplating wheels 3 are respectively located on both sides of the inside of the electroplating tank 21 and rotate synchronously; a conductive mechanism 5 is also installed on the fixed frame 1, the conductive mechanism 5 comprises two conductive belts 51, the two conductive belts 51 are respectively partially fitted with the two electroplating wheels 3 to realize the conductive function.

[0031] A synchronous drive mechanism 4 is provided outside the electroplating tank 21. The synchronous drive mechanism 4 includes a drive motor 42 and two driving wheels 41 driven by the drive motor 42 and located on both sides of the outside of the electroplating tank 21. The two driving wheels 41 are connected and fixed by a synchronous shaft. A drive shaft 31 extending out of the electroplating tank 21 is provided at the center of the electroplating wheel 3. A driven wheel 43 is fixed to the outer end of the drive shaft 31. The two driving wheels 41 are connected to the driven wheels 43 on the corresponding sides through belt transmission or chain transmission. The electroplating wheel 3 realizes synchronous rotation of the double-sided electroplating wheels driven by one driving motor through the synchronous drive mechanism 4 to prevent uneven force on the film.

[0032] The conductive mechanism 5 also includes a plurality of pairs of synchronous wheels 52 connected by synchronous shafts. Each synchronous wheel 52 limits the conductive belt 51 so that the portion of the conductive belt 51 in the electroplating tank 21 fits against the lower portion of the electroplating wheel 3 and forms a closed loop.

[0033] The width of the conductive belt 51 does not exceed half of the width of the electroplating wheel 3. The electroplating wheel 3 is provided with limiting wheels 32 for limiting the film near the feeding end and the discharging end. The width of the limiting wheel 32 does not exceed half of the width of the electroplating wheel 3 and is staggered with the conductive belt 51. When the electroplating wheel 3 rotates, the film and the conductive belt 51 are driven to move at the same time. The staggered position of the limiting wheel 32 for limiting the film and the conductive belt 51 can prevent the conductive belt 51 from interfering with the film.

[0034] The electroplating tank 21 is provided with an arc-shaped double-layer titanium blue 22, and the arc of the double-layer titanium blue 22 is adapted to the electroplating wheel 3. The double-layer titanium blue 22 includes an outer layer titanium blue 22b close to the arc-shaped bottom wall of the electroplating tank 21 and an inner layer titanium blue 22a located on the side of the outer layer titanium blue 22b away from the arc-shaped bottom wall. The inner layer titanium blue 22a is provided with an arc plate 23 with an L-shaped cross section on both sides for fixing the inner layer titanium blue 22a in the electroplating tank 21. The circumferential surface where the outer edge of the electroplating wheel 3 is located is located between the inner layer titanium blue 22a and the outer layer titanium blue 22b. The double layer titanium blue 22 is also provided with a plurality of evenly arranged feed pipes 24, each of which is provided with a plurality of feed holes. Driven by the electroplating wheel 3, the film passes between the double-layer titanium blue 22, and its two sides are electroplated by the inner layer titanium blue 22a and the outer layer titanium blue 22b respectively. The electroplating process can be completed only once, thereby improving the electroplating efficiency. The feed pipe 24 provides the electroplating solution or other materials required for electroplating into the electroplating tank 21, making the feeding more convenient.

[0035] An extraction rack 7 is provided above the electroplating tank 21, and the extraction rack 7 is fixedly connected to the electroplating tank 21. The electroplating tank 21 is detachably mounted on the fixing rack 1 and can be lifted up by the extraction rack 7. When the electroplating tank 21 needs to be cleaned, the extraction rack 7 can be more conveniently assembled and disassembled for easy cleaning.

[0036] A feed limiting roller 61 and a discharge limiting roller 62 are respectively provided above the electroplating mechanism 2 near the feed end and the discharge end. The feed limiting roller 61 and the discharge limiting roller 62 are both close to the electroplating wheel 3 so that the film is close to the electroplating wheel 3.

[0037] The horizontal double-sided ultra-thin film electroplating equipment of this embodiment, when working, the feeding roller 6 conveys the film to be electroplated to the electroplating wheel 3, and the two sides of the film are driven by the electroplating wheels 3 on both sides respectively. Under the rotation drive of the electroplating wheel 3, the film passes through the double-layer titanium blue 22 to achieve electroplating, and is output through the discharging limit roller 62. In this process, the two electroplating wheels 3 are synchronized by the synchronous drive mechanism 4. When the drive motor 42 drives, the two electroplating wheels 3 always keep synchronization, and the conductive belt 51 in the conductive mechanism 5 supplies power for the electroplating process. At the same time, in order to prevent the conductive belt 51 from interfering with the electroplating wheel 3, the conductive belt 51 also moves with the rotation of the electroplating wheel 3. After working for a long time, the electroplating tank 21 often needs to be cleaned of its waste residue. It is only necessary to grab the extraction frame 7 by the crane to conveniently assemble and disassemble the electroplating tank 21, which is also more convenient for cleaning.

[0038] The beneficial effects of the present invention are as follows: by cooperating with the electroplating wheel and the arc-shaped electroplating tank and adopting double-sided anode double titanium blue electroplating, both sides of the ultra-thin film can be electroplated at one time, and at the same time, the two electroplating wheels are synchronized through a synchronous drive mechanism, which can make the film tension more uniform and will not affect the film quality; in addition, the electroplating equipment adopts a conductive belt that fits the lower part of the electroplating wheel to achieve conductivity, and the conductive position is located in the electroplating area, which can effectively reduce the phenomenon of less air on the film surface and save energy; and by setting an extraction rack fixed to the electroplating tank, the electroplating tank can be installed and disassembled more conveniently and efficiently, and cleaning is more convenient and efficient.

A person skilled in the art may change, modify and vary the above embodiments within the scope of the present invention.
