摘要:

当工件的温度与电镀液的温度存在差异时，工件浸入电镀液会立即发生热交换效应。这种热交换会导致电镀液的温度迅速上升或下降，从而影响电镀过程的稳定性和镀层质量。为了有效控制电镀液温度，进而提升工件电镀的质量，研究工件浸入电镀液时的温度状态控制方法。建立电镀液温度状态控制架构，通过温度传感器实时采集工件浸入电镀液的温度数据，运用移动平均滤波和非模型修正算法对采集的电镀液的温度数据进行校正，控制电镀液温度的波动范围，降低热交换带来的影响。通过专家PID控制器对经过校正后的数据输出温度控制指令，调节电镀槽的温度，从而实现工件浸入电镀液时温度状态的精确控制。实验分析结果显示：该控制方法能够在恒温设定、单次变温设定以及多次变温设定下均实现精确的温度控制，并且在多次电镀液温度控制过程中能够保持较低的超调量，这表明该方法具备稳定的温度控制能力，提高镀层质量。

Abstract:

When there is a difference between the temperature of the workpiece and the temperature of the plating solution, the workpiece will immediately undergo heat exchange when it invades the plating solution. This heat exchange can cause the temperature of the plating solution to rapidly rise or fall, thereby affecting the stability of the plating process and the quality of the coating. In order to effectively control the temperature of the electroplating solution and improve the quality of the workpiece electroplating, a method for controlling the temperature state of the workpiece immersed in the electroplating solution is studied. Establish a temperature state control architecture for electroplating solution, collect real-time temperature data of workpiece intrusion into electroplating solution through temperature sensors, use moving average filtering and non-model correction algorithms to correct the collected temperature data of electroplating solution, control the fluctuation range of electroplating solution temperature, and reduce the impact of heat exchange. By using an expert PID controller to output temperature control instructions on the calibrated data, the temperature of the plating tank can be adjusted to achieve precise control of the temperature state when the workpiece invades the plating solution. The experimental analysis results show that this control method can achieve precise temperature control under constant temperature setting, single temperature change setting, and multiple temperature change settings, and can maintain a low overshoot during multiple electroplating solution temperature control processes. This indicates that the method has stable temperature control ability and improves coating quality.
