[0002] With the advent of the 5G era, the requirements for the quality of electroplated copper in electrical interconnection are getting higher and higher, posing challenges to the flatness and reliability of electroplated copper. The initial surface roughness of nickel-phosphorus plated metal sheets is relatively high and the conductivity is poor, resulting in poor flatness and reliability of direct electroplated copper. Electroless copper plating is an effective surface treatment method to achieve flat and reliable electroplated copper on the surface of nickel-phosphorus plated metal sheets, which can improve the leveling effect and reliability of electroplated copper. The treatment method of electroless copper plating is to immerse the metal sheet in the electroless copper plating solution for about 10 minutes, take it out after depositing a copper layer of about 2 μm on the surface of the metal sheet. The electroless copper plating solution is composed of formaldehyde, copper sulfate, sodium hydroxide and sodium potassium tartrate. The volatilized gas and the solution remaining on the metal sheet will harm people's bodies to a certain extent, and the safety is not high. Therefore, it is necessary to improve the existing electroless copper plating device. Content of the Utility Model

[0021] The moving mechanism 2 includes a lead screw 20, a base 21, a first motor 22, and a first nut 23. The base 21 is fixed on the inner side wall of the box body 1. One end of the lead screw 20 is rotatably connected to the base 21, and the other end of the lead screw 20 passes through the box body 1 and is fixedly connected to the output end of the first motor 22. The first motor 22 is fixedly installed on the outer wall of the box body 1. The first nut 23 is screwed onto the lead screw 20, and the bottom end of the first nut 23 is fixedly connected to a material transporting mechanism 3;

[0022] One side of the partition board 4 is provided with a groove adapted to the shape of the convex frame 7, and a second nut 40 is penetrated through the middle of the partition board 4. The second nut 40 is screwed onto the lead screw 20.

[0023] Specifically, there is electroless copper plating solution in the copper plating bath 5. A metal sheet is installed on the material transporting mechanism 3. The material transporting mechanism 3 is moved above the copper plating bath 5 through the moving mechanism 2. The material transporting mechanism 3 operates to immerse the metal sheet into the copper plating bath 5. After 10 minutes of electroless copper plating, the material transporting mechanism 3 is operated to lift the metal sheet. The material transporting mechanism 3 is moved above the cleaning bath 6 through the moving mechanism 2. At this time, the partition plate 4 also moves to the position of the convex frame 7, isolating the copper plating bath 5 from the cleaning bath 6 and the outside. The material transporting mechanism 3 operates to lower the metal sheet into the cleaning bath 6 for cleaning. Finally, the material transporting mechanism 3 is operated to lift the metal sheet and remove the metal sheet.

[0024] The material transporting mechanism 3 includes: a fixing frame 30, an electric push rod 31, a sleeve 32, a curved rod 33, a connecting rod 34, a connecting plate 35, and a hook 36. The top of the fixing frame 30 is fixedly connected to the first lead screw nut 23. The electric push rod 31 is fixedly installed on the fixing frame 30. Both sides of the bottom end of the fixing frame 30 are fixedly connected to the sleeve 32. The upper section of the curved rod 33 is inserted into the sleeve 32.

[0025] Specifically, the metal sheet is drilled. The metal sheet is hung on the hook 36. When the material transporting mechanism 3 moves to the designated position, the electric push rod 31 extends, driving the lower end of the connecting rod 34 to move downward and the upper end to rotate inward. The upper end of the curved rod 33 moves inward along the direction of the sleeve 32. The lower end of the curved rod 33 moves inward and downward, driving the opposite hooks 36 to align, so that the metal sheet on the hook 36 will not fall off. At the same time, the hook 36 moves downward, driving the metal sheet to reach the designated processing position. When reaching the limit position, the limit post 37 is stuck at the upper end of the sleeve 32. After the processing is completed, the electric push rod 31 contracts, and the device runs in the reverse direction, driving the hook 36 back to the original position.

[0027] Specifically, the washing water is transported to the spray head 60 through the water supply channel 64, the second motor 63 is turned on, the driving wheel 61 drives the driven wheel 62 to rotate, so that the two arms of the spray head 60 rotate to spray water to clean the metal sheet, preventing the corrosive liquid from harming the staff. There is a water outlet at the bottom of the cleaning pool 6 to facilitate the discharge of the waste water after cleaning.

[0028] It also includes an adding device, which includes a liquid storage box 50, and the outlet of the liquid storage box 50 is fixedly connected to a drug adding pipeline 51, a one-way electric valve 52 is provided between the outlet of the liquid storage box 50 and the drug adding pipeline 51, and the drug adding pipeline 51 passes through the side wall of the box body 1 to set the outlet of the drug adding pipeline 51 above the copper plating pool 5.

[0029] Specifically, the chemical copper plating liquid raw materials are placed in the liquid storage box 50, and when replenishment is needed, the one-way electric valve 52 is opened, and the chemical copper plating liquid raw materials enter the copper plating pool through the dosing pipeline 51. The chemical copper plating liquid can be replenished without opening the box 1, thereby improving safety.

[0030] A hatch 8 is provided on one side of the box body 1 close to the cleaning tank 6 .

[0031] The working principle and use process of the utility model are as follows: a hole is punched on the metal sheet to be processed, and chemical copper plating liquid is added to the copper plating pool 5 through the adding device, and the hatch 8 is opened to ensure that the partition 4 and the convex frame 7 seal the space where the copper plating pool 5 is located at this time, and the metal sheet is hung on the hook 36, and the hatch 8 is closed, and the material transport mechanism 3 is moved to the top of the copper plating pool 5 through the moving mechanism 2, and the electric push rod 31 is opened to immerse the metal sheet in the chemical copper plating liquid.

It is obvious that the specific implementation of the utility model is not limited to the above-mentioned method. As long as various improvements are made using the method concept and technical solution of the utility model, or are directly applied to other occasions without improvement, they are all within the protection scope of the utility model.
