Description

technical field [0001] The invention relates to a method for manufacturing a potentiometer reed, in particular to a method for manufacturing a potentiometer reed assembly based on spot welding. Background technique [0002] Conductive plastic potentiometer is an important potentiometer, which is mainly used for angular displacement measurement of servo motors and other equipment, and feedbacks the absolute position of rotating parts such as servo motor shafts. The basic principle is to use the brush wire on the reed assembly to Or contact and slide on the resistor body to change the resistance value between the fixed electrode and the reed assembly, thereby generating a changing voltage signal to achieve the purpose of detecting the rotation angle. The reed assembly inside the conductive plastic potentiometer is an important voltage detection component, which needs to have good conductivity and elasticity, so the manufacturing process requirements for the reed assembly are r...

AI Technical Summary

Problems solved by technology

Among them, the brush wire is generally made of alloy wire, and the alloy wire is very thin. In the process of fixing multiple alloy wires side by side, the traditional method generally uses brazing welding method to fix them, and flux is needed to achieve a good welding effect. However, flux is not easy to clean and is prone to residues, so cleaning and drying processes are required, which increases the process flow and manufacturing cycle time, and reduces production efficiency; at the same time, in the traditional manufacturing process of reed components, in addition to winding All other processes are manually operated. In order to ensure that the product meets the technical requirements, the operator needs to follow the steps to complete it step by step, which further prolongs the production cycle time of the reed assembly and reduces the production efficiency. Moreover, the consistency of product quality is not guaranteed. As a result, the elasticity and conductivity of the reed components are not fully guaranteed

[0004] In addition, in the traditional processing method of reeds, the reed raw material strip is generally cut into multiple reed raw materials, and then each reed raw material is processed independently to form a reed. This processing method is more efficient. Low, and the consistency of the reed is not fully guaranteed
