Description

Technical Field

[0001] The utility model relates to the technical field of electroplating, in particular to an automatic adding mechanism for process chemicals. Background Art

[0002] Electroplating is the process of plating a thin layer of other metals or alloys on certain metal surfaces using the principle of electrolysis. It is a process that uses electrolysis to attach a layer of metal film to the surface of metal or other material parts, thereby preventing metal oxidation, improving wear resistance, conductivity, reflectivity, corrosion resistance, and enhancing aesthetics. When producing circuit boards, the circuit boards need to be placed in a solution tank for electroplating. The electroplating solution in the solution tank is a key factor in ensuring stable production quality. At present, the addition of electroplating solution is generally done manually at intervals, and the operation and management are relatively troublesome, so it is necessary to use an automatic adding mechanism to add the electroplating solution.

[0019] Working principle of the utility model: When the production equipment is started, the adding system is started synchronously, and the main control PLC of the production line is connected and controlled according to the actual production time; the ampere-minute (hour) of the production process will record the total ampere value and upload it to the main control PLC. The program sets the relative consumption of chemicals per unit electroplating time (ampere-minute (hour)) and the required equivalent value (this value is the value uploaded in the ampere-minute (hour)). When the required added chemicals are consumed to the set value (set according to the required concentration ratio of each chemical in the process tank), the PLC starts the quantitative pump of the adding system to add chemicals to the set upper limit value. This continuous operation maintains the addition of chemicals in the production process and achieves the function of automatic addition.
