Background
At present, in the production of circuit boards, one of the processes is to copper-plate the circuit board so that the circuit board can connect and conduct each electronic element, and the hardness and the corresponding flexibility of the circuit board can be enhanced, so that the circuit board is not easy to break. The copper liquid for copper plating of the circuit board is copper sulfate solution, copper oxide powder and sulfuric acid are reacted under the condition of introducing oxygen in the production of the copper sulfate solution, and a stirring reaction device is required for the reaction.
The traditional copper oxide powder stirring reaction device mainly comprises: 1. a spiral lifting mechanism (power: 1.5 KW); 2. A spiral adding mechanism (power: 0.2-0.4 KW); 3. a stirring mechanism (power: 0.75 KW); 4. the bubbling fan (power: 1.5KW) is composed of four parts, the total power is about 4.15KW, the traditional copper oxide powder stirring reaction device has more components and mechanisms, the manufacturing cost is high, the maintenance cost of the traditional copper oxide powder stirring reaction device is relatively high, and meanwhile, the power consumption of the traditional copper oxide powder stirring reaction device is relatively high.
The traditional copper oxide powder stirring reaction device has the working process that: 1. the copper oxide powder is lifted to the spiral adding mechanism through the spiral lifting mechanism; 2. the spiral adding mechanism is used for adding the copper oxide powder into the stirring tank through the rotation of a screw blade (the drop height between a blanking port and the liquid level is 300-400 MM); 3. the stirring motor uniformly stirs the copper oxide powder and the sulfuric acid liquid in the tank, and the bubbling fan is used for introducing air to the tank bottom to accelerate the substance reaction.
However, because the dropping port and the liquid level have a 300-400MM drop, more dust is generated and dispersed in a space formed by the dropping port and the liquid level in the dropping process of the copper oxide powder, the copper oxide and the sulfuric acid liquid react under the condition of introducing oxygen to release heat, so that the air pressure in the tank is greater than the air pressure outside the tank, and the dispersed dust between the dropping port and the liquid level of the sulfuric acid easily leaks out of the tank through equipment gaps.
Meanwhile, the amount of the added copper oxide powder needs to be fed back to a system according to the concentration or current value of copper sulfate in the copper plating reaction tank of the circuit board before adding, and then the adding amount of the copper oxide powder is controlled by controlling the running time or the rotating angle of an adding motor through program setting.
