Intelligent electronic spot welder and spot welding method thereof

Abstract

The invention relates to an intelligent electronic spot welder and a spot welding method thereof. The spot welder comprises a host machine provided with a singlechip and a welding database, and a machine head; the machine head comprises a driving device, a front shaft and a welding head; and a detector and a braking device are respectively connected with the front shaft. The detector transmits the acquired data to the singlechip so as to make the welding head automatically perform welding action through the host machine. The intelligent electronic spot welding method comprises the following steps of: (1) establishing a welding parameter database; (2) measuring the diameter of an enameled wire to be processed; (3) outputting a paint-removing pulse for paint removal; (4) outputting a welding pulse for welding; (5) and measuring or performing repair welding. The Intelligent electronic spot welder has real-time detection and repair welding function, namely synchronously welds and detects welding spot quality, and detects a welding spot once the welding spot is welded to form a closed-loop automatic detection system, solves the problems of no detection of the welding spot quality afterwelding, and insufficient welding and wire break during spot welding of the conventional spot welder, and improves the reliability of processing electronic components in the industries of communication, aviation and aerospace and advanced medical equipment.

AI Technical Summary

Problems solved by technology

Although the electronic spot welding machines in the past are also micro spot welding, they also have a host, a plate frame and a pressure device, but they are all foot-operated manual spot welding equipment, which has serious defects in the welding process of electronic components. , that is, only welding without detecting the welding quality of solder joints

In the case of certain welding parameters in this operation mode, the quality of the solder joints mainly depends on the thickness of the solder joints. If the welding pressure of the pedal is too small, the thickness of the solder joints will be too large, and the contact surface of the solder joints will not form an alloy surface, thus It causes the virtual welding phenomenon of the solder joints, which reduces the high temperature and low temperature resistance of the solder joints, and leads to the unreliability of electronic components.

If the welding pressure of the foot pedal is too high, the thickness of the solder joints will be too small, which will cause the enameled wires of the solder joints to break, which is an increasingly serious problem in the production of electronic components in the aerospace industry and advanced medical equipment industry.
