Description

Technical Field

[0001] This utility model relates to the technical field of chemical copper plating production equipment, and in particular to an online purification and regeneration device for colloidal palladium activation solution. Background Technology

[0002] The online purification and regeneration device for colloidal palladium activating solution is a specialized piece of equipment for treating and regenerating colloidal palladium activating solution. It is primarily used in the production process of chemical copper plating wire to rapidly process the colloidal palladium activating solution online, ensuring the stability of the production process and product quality. Furthermore, this device can also be applied to other fields requiring purification and regeneration.

[0003] The working principle of the online purification and regeneration device for colloidal palladium activation solution is as follows: the colloidal palladium activation solution is first pre-treated in the activation tank and then pumped to the purification and regeneration tank by a metering pump. In the purification and regeneration tank, the activation solution reacts with the purification materials such as pure tin balls in the basket, removing by-products from the liquid through an oxidation-reduction reaction and improving the stability of the liquid. At the same time, the tin ions in the purification materials can promote the regeneration of colloidal palladium particles, improving the dispersibility and stability of colloidal palladium. The purified and regenerated liquid is returned to the activation tank through a return pipe, forming a closed loop and realizing continuous online treatment.

[0004] Based on this, Chinese patent CN209619448U discloses an online purification and regeneration device for colloidal palladium activation solution, which includes an activation tank, a metering pump, a purification and regeneration tank, a purification basket, a temperature control heating system, a reflux pipe, and valves. The activation tank, metering pump, and purification and regeneration tank are all equipped with an outlet and an inlet. The inlet of the metering pump is connected to the outlet of the activation tank, and the outlet of the metering pump is connected to the inlet of the purification and regeneration tank. The outlet of the purification and regeneration tank is connected to the activation tank via the reflux pipe, forming a closed loop for the flow of the solution. This patent document discloses an online purification and regeneration device for colloidal palladium activation solution. By adding a purification device next to the activation tank of the chemical copper plating wire, which can hold pure tin balls, pure tin bars, or pure tin blocks, the device allows for rapid online treatment of the colloidal palladium activation solution, reducing the content of by-products in the solution, thereby improving the stability of the solution and extending its service life.

[0005] However, the aforementioned online purification and regeneration devices still suffer from technical problems due to their complex structure and difficulty in placement. Specifically, in the industrial application of electroless copper plating, manufacturers expect online purification and regeneration devices for colloidal palladium activating solutions to have a more compact structural layout, so as to place them near the electroless copper plating production line for easy integration into the electroless copper plating process.

[0026] Please refer to the following: Figures 1 to 2 The present invention relates to an online purification and regeneration device for colloidal palladium activation solution, comprising: a base 1, an inlet mechanism 2, an activation section 3, a purification and regeneration section 4, a circulation mechanism 5, a purification material release section 6, a temperature control structure 7, and an outlet structure 8; the inlet mechanism 2 is disposed on the base 1, the activation section 3 is disposed adjacent to the inlet mechanism 2 on the base 1, and the purification and regeneration section 4 is connected to the activation section 3; the circulation mechanism 5 is disposed on the base 1 and connects the activation section 3 and the purification and regeneration section 4 respectively; the purification material release section 6 is connected to the purification and regeneration section 4; the temperature control structure 7 is disposed on the purification and regeneration section 4; and the outlet structure 8 is connected to the activation section 3 at one end of the base 1.

[0027] Specifically, when the online purification and regeneration device for colloidal palladium activation solution of this invention is in operation, the colloidal palladium activation solution to be treated is introduced from the external chemical copper plating production line into the activation section 3 via the inlet mechanism 2. The activation section 3 temporarily stores the colloidal palladium activation solution to be treated. Subsequently, the circulation mechanism 5 pumps the liquid in the activation section 3 to the purification and regeneration section 4. The purification and regeneration section 4 is equipped with a purification material release section 6, which contains purification materials such as pure tin balls, pure tin bars, or pure tin blocks. These materials can be released into the purification and regeneration section 4 as needed. The temperature control structure 7 located on the side of the purification and regeneration section 4 can be used to control the temperature of the liquid inside, ensuring that the purification process is carried out at a preset temperature. The purified liquid can then flow back from the purification and regeneration section 4 to the activation section 3, forming a closed loop, thereby achieving continuous online processing. The processed colloidal palladium activation solution is then exported from the outlet structure 8 to the external chemical copper plating production line. Therefore, this utility model presents a technical solution for an online purification and regeneration device for colloidal palladium activation solution that is compact in structure and easy to install in a chemical copper plating production line.

[0033] Specifically, the external activation solution to be processed can flow from the external production line into the first outlet pipe 203 via the inlet pipe 202 under the control of the inlet pump 201, and then into the activation section 3. Subsequently, the circulation pump 502 can transfer the aforementioned activation solution from the activation section 3 through the rotary structure 504, from the first circulation loop 503 to the second circulation loop 505, flowing into the purification and regeneration section 4. Then, the purification material release section 6 can release purification materials such as solder balls into the purification and regeneration section 4. Simultaneously, the temperature control connector 701, under the control of a preset program, controls the heating structure 702 to control the internal temperature of the purification and regeneration section 4. Finally, the purified activation solution can flow back to the external production line from the second outlet pipe 801 under the control of the outlet control valve 802.

[0034] In summary, the online purification and regeneration device for colloidal palladium activation solution of this utility model comprises a base 1, an inlet mechanism 2, an activation section 3, a purification and regeneration section 4, a circulation mechanism 5, a purification material release section 6, a temperature control structure 7, and an outlet structure 8.
