Common-mode inductor production process

Abstract

The invention discloses a common-mode inductor production process which comprises the following steps of copper wire cutting, winding, gluing, pin cutting, soldering, and inspection. The gluing step is executed after the winding step and before the soldering step. The soldering step is executed after the pin cutting step. The gluing step comprises gluing an inner ring to fix two inner pins. The pin cutting step comprises fixing a pin distance by a manual pin cutting device, and then cutting the extended length of the pin. The common-mode inductor production process reduces four steps by simplification and improvement, achieves a qualified rate of the finished products to 99%, simplifies the operations, reduces manpower expenditure, greatly improves production efficiency, and has a certaineconomic value.

Description

technical field [0001] The invention relates to the technical field of inductance processing and manufacturing, in particular to a simplified common-mode inductance production process. Background technique [0002] Common-mode inductors are one of the common electronic components in electronic circuits, and their production process is relatively complicated, with many procedures and low production efficiency. The conventional production process of horizontal common mode inductors includes 10 processes, which are copper wire cutting, winding, pre-cutting, bending angle, soldering, dispensing, post-sizing, cutting, self-calibration, and inspection. There may be the following problems: 1. During the soldering process, the position of the solder is unstable and there are many reworks; 2. During the cutting process, the pins are too long, the efficiency of inserting into the cutting holes is low, and the cut out pins have a high defect rate, sometimes Will need further leg adj...
