Abstract
Description
Technical Field
[0001] The utility model relates to the field of circuit board production, in particular to an automatic sulfuric acid adding system for circuit board production. Background Art
[0002] Concentrated sulfuric acid is often used in existing factories. In the circuit board production process, sulfuric acid is also needed for etching of the circuit board. However, in the existing technology, 98% concentrated sulfuric acid is usually used. Concentrated sulfuric acid is highly corrosive, so workers need to dilute and add it manually. Concentrated sulfuric acid is usually shipped back to the factory in barrels. Workers wear safety protection equipment, dilute it manually, adjust the concentration for engineering use, and then manually add it to the equipment. This process is time-consuming and labor-intensive, and is also accompanied by personnel safety issues. During the concentrated sulfuric acid dilution process, there may be safety hazards caused by improper operation of the personnel during the dilution process.
[0003] Based on this, in order to improve the efficiency of concentrated sulfuric acid dilution and protect the personal safety of workers, and reduce safety hazards caused by misoperation, this design proposes an automatic sulfuric acid addition system for circuit board production.

[0013] The present invention is further explained in detail below in conjunction with the accompanying drawings of the specification, but the protection scope of the present invention is not limited thereto.
[0014] A system for automatically adding sulfuric acid for producing circuit boards, comprising: a medicine adding tube 1, a sealing member 2, a medicine barrel 3, and a medicine conveying pipeline 4, wherein the medicine adding tube 1 is installed on the top of the medicine barrel 3, the medicine barrel 3 is cylindrical in structure, and a sealing member 2 is installed between the medicine barrel 3 and the medicine adding tube 1, wherein the medicine conveying pipeline 4 is installed at the lower part of the medicine barrel 3, the other end of the medicine conveying pipeline 4 is connected to a shunt pipe 5, a dosing valve 6 is installed at the outlet end of the shunt pipe 5, the other end of the dosing valve 6 is connected to an automatic adding tank 7, and the other end of the automatic adding tank 7 is connected to production equipment 8.
[0015] Specifically, the diverter pipe 5 may be provided with two outlets or multiple outlets.
[0016] Specifically, the automatic adding tank 7 is provided with an automatic water adding device and a stirring device.
[0017] Specifically, the medicine barrel 3 stores sulfuric acid with a concentration of 50%.
[0018] Working principle:
[0019] A sulfuric acid automatic adding system for circuit board production comprises: a medicine solution adding pipe 1, a sealing member 2, a medicine solution barrel 3, a medicine solution conveying pipeline 4, a diversion pipe 5, a dosing valve 6, an automatic adding tank 7, and production equipment 8. When working, 50% of the sulfuric acid is transported back to the factory by a tank truck, and the medicine solution is first extracted from the tank truck and stored in the medicine solution barrel by a pump in cooperation with the medicine solution adding pipe 1. When sulfuric acid is needed, by opening the dosing valve 6, 50% of the sulfuric acid will be conveyed to the automatic adding tank 7 through the medicine solution conveying pipeline 4 and the diversion pipe 5. In the automatic adding tank 7, it is diluted in a certain proportion by adding water and stirring. After dilution, it is transported from the pipeline to each production equipment 8 for use. Workers only need to open the dosing valve 6 to complete the process. This equipment improves the dilution efficiency of the medicine solution and ensures the personal safety of the workers.
