A micro memory card low power consumption ultrasonic welding device

Abstract

The utility model discloses a kind of miniature memory card low-power consumption ultrasonic welding equipment, belong to electronic component processing equipment technical field, including inverted U-shaped frame integrated drive assembly, cooling unit and control unit. Ultrasonic generator with titanium alloy welding head of the maximum output power 40W of combination is realized millimeter level positioning by synchronous belt driving cooperation guide pillar guide structure, and mechanical friction loss reduces 30%. Piezoelectric ceramic transducer operating temperature fluctuation is controlled within ±2 ℃ by double helical flow passage cooling system, and comprehensive power consumption is reduced by 45% under traditional equipment. Key motion components are built-in in frame structure, cooperate with movable cover plate with transparent observation window, and have dust protection and operation visibility. The micro-protruding structure of titanium alloy welding head combines real-time pressure feedback module, so that welding pressure is stabilized in 0.5-1.2N interval, to realize gold finger submicron level welding precision. Temperature control module cooperates with ultrasonic frequency regulation, to ensure that welding point contact resistance is less than 0.01Ω, to improve yield and shorten production rhythm.
