A metal material welding method and control system based on ultrasonic welding

Abstract

The invention belongs to the technical field of metal workpiece welding, and discloses a metal material welding method and control system based on ultrasonic welding; the thickness of raw materials and welding conditions are detected through a signal acquisition and analysis module, and the detected information is transmitted to a central control module ; The central control module controls the emission module to select the appropriate power for ultrasonic radiation according to the information collected and analyzed, and outputs it; the signal acquisition and analysis module detects the ultrasonic emission time, energy conversion time and welding conditions, and transmits the detected information To the central control module, the system is intelligently regulated through the central control module. By using the LBFA algorithm for the central control system, the present invention satisfies the real-time resource scheduling task of the central control system under the condition of massive nodes, greatly improves the cooperation and coordination of each system, and effectively promotes the stability, operability and reliability.

Description

technical field [0001] The invention belongs to the technical field of metal welding, and in particular relates to a metal material welding method and control system based on ultrasonic welding. Background technique [0002] At present, the existing technology commonly used in the industry is as follows: ultrasonic welding uses high-frequency vibration waves to transmit to the surfaces of two objects to be welded, and under pressure, the surfaces of the two objects are rubbed against each other to form a gap between the molecular layers. of joining. Whether it is ultrasonic plastic welding or ultrasonic metal welding, the basic principles are roughly the same, but due to the difference between metal materials and plastics, ultrasonic metal welding requires higher precision, higher power capacity and low impedance, so the ultrasonic generator The requirements for components such as components and transducers are more stringent. It is these requirements that make the early ul...

Problems solved by technology

[0005] (1) Due to the complexity of the ultrasonic welding system, the mutual cooperation of various systems is required in the welding process to form a tightly integrated overall system to operate stably. If the coordination and coordination of the entire system are inconsistent, the system will be stable. There are certain problems in performance, operability and reliability

[0006] (2) The amount of data analysis and collection is large, and the data analysis is not accurate enough, which can easily cause various errors and have a serious impact on welding quality

[0007] (3) The traditional tracking of the resonance frequency of the ultrasonic transducer is difficult to match with the vibration frequency, which cannot be kept consistent, and the welding efficiency is low
