A silver chloride continuous electroplating equipment for silver-plated yarn

Abstract

The invention relates to silver chloride continuous electroplating equipment for a silver-plated yarn, which comprises an electroplating tank, a negative electrode and a positive electrode, wherein the negative electrode is a negative electrode plate arranged in the electroplating tank; the positive electrode is a positive conductive roller capable of driving the silver-plated yarn to move in the electroplating tank; at least three positive conductive rollers are provided, and the positive conductive rollers are transversely arranged on the same side of the negative electrode plate; and the positive conductive rollers are arranged from top to bottom in the electroplating tank so that the distances from the anode conductive rollers at different positions from top to bottom to the negative electrode plate are gradually reduced. In the equipment provided by the invention, the silver-plated yarn gets closer to the negative electrode plate along with the rotation of the positive conductive rollers; the yarn is primarily modified by the positive conductive roller farthest away from the negative electrode plate; along with the silver-plated yarn getting closer to the negative electrode plate, the degree of silver chloride modification is gradually enhanced; when the silver-plated yarn reaches the positive conductive roller closest to the negative electrode plate, the silver chloride modification is the strongest so as to realize precision control modification of silver chloride.

AI Technical Summary

Problems solved by technology

At present, in the production of yarn materials for flexible textile electrodes, commonly used yarn materials include silver-plated and other metal-plated yarns, pure metal or its oxide yarns, and conductive materials such as metals and carbon blacks dispersed and filled with fiber materials. , these yarns are made into flexible ECG electrodes through textile molding technology. However, in the actual ECG test, due to the high polarization resistance of the material, it is easy to cause high impedance between the electrode and the skin, so that the tested ECG The signal data is unstable and noisy, especially in the case of dynamic testing. At the same time, the manufacturing process is complicated and the cost is high

[0003] As a common material for electrodes, silver-silver chloride has low polarization resistance. The electrodes made of this material can reduce the impedance between the skin and the electrodes. It is one of the best electrode materials for ECG electrodes. Currently Most of the commercial viscose ECG electrodes are silver-plated-silver chloride metal sheets, which have good performance, but they are not flexible and wearable, and are not suitable for long-term ECG monitoring.

The silver-plated-silver chloride yarn not only has excellent ECG signal acquisition performance, but also can be processed through subsequent textile processing to make flexible ECG electrodes. However, most of the existing silver-plated yarns are modified with silver chloride in the laboratory. Static electroplating, small batch intermittent production; because it is difficult to accurately control the electroplating environment and continuously modify the yarn in a continuous dynamic environment, there is no relatively stable and reliable yarn silver plating-silver chloride production process and its Appearance of equipment, especially serial production equipment
