    全自动超声波清洗机:超声波焊接机工作原理
    2019-8-28 19:20:30
    物体振动时会发出声音。科学家称每秒振动的次数为声音的频率(赫兹)。人类耳朵能听到的声波频率在16HZ到20KHz(千赫兹)之间。因此,当物体振动超过一定的频率,即高于人耳的阈值时,人就听不出来,这种声波称为“超声波”。超声波频率,通常用于医学诊断,范围从1到5兆赫。
    When an object vibrates, it makes a sound. Scientists call the number of vibrations per second the frequency of sound (hertz). The frequency of sound waves that human ears can hear ranges from 16 HZ to 20 KHz (kilohertz). Therefore, when the vibration of an object exceeds a certain frequency, that is, the threshold value of the human ear, the human can not hear it. This kind of sound wave is called "ultrasound". Ultrasound frequency, usually used in medical diagnosis, ranges from 1 to 5 MHz.
    虽然人类听不见超声波,但许多动物能听到。他们可以用超声波“导航”、追踪食物或躲避危险物体。你可能见过很多蝙蝠在夏天的夜晚在院子里飞来飞去,为什么它们在没有光的情况下飞行而不会迷路呢?原因是蝙蝠发出的超声波在20到10万赫兹之间,就像一个活跃的“雷达站”。蝙蝠利用这种“雷达”来识别它们前方的昆虫或障碍物。
    Although humans can't hear ultrasound, many animals can hear it. They can use ultrasound to "navigate", track food or avoid dangerous objects. You may have seen many bats flying around the yard on summer nights. Why don't they get lost without light? The reason is that bats emit ultrasound between 20 and 100,000 hertz, like an active "radar station". Bats use this radar to identify insects or obstacles in front of them.
    直到第一次世界大战,我们人类才学会使用超声波。超声波利用“声纳”原理探测水中的物体及其状态,比如潜艇的位置。此时,一系列不同频率的超声波被发送到水中,并记录和处理反射回波。根据回波信号的特点,可以估计出被探测目标的距离、形状和动态变化。超声波最早的医学应用是在1942年,奥地利医生杜斯克首先使用超声波技术扫描大脑结构;然后在20世纪60年代,医生开始使用超声波检测腹部器官。超声扫描技术已成为现代医学诊断不可缺少的工具。

    江南彩票 It was not until World War I that we humans learned to use ultrasound. Ultrasound uses the principle of "sonar" to detect objects and their states in water, such as the position of submarines. At this time, a series of different frequencies of ultrasonic waves are sent to the water, and the reflected echoes are recorded and processed. According to the characteristics of the echo signal, the range, shape and dynamic change of the detected target can be estimated. The earliest medical application of ultrasound was in 1942, when Austrian doctor Dusk first used ultrasound technology to scan brain structures; then in the 1960s, doctors began to use ultrasound to detect abdominal organs. Ultrasound scanning technology has become an indispensable tool for modern medical diagnosis.

    医学超声检查的工作原理与声纳有一定的相似性,即超声波是通过声波传输到人体的。当它在体内遇到界面时,会被反射和折射,并可能被人体组织吸收和衰减。由于人体组织的形状和结构不同,它们会反射和折射超声波,并在不同程度上吸收它们。此外,结合解剖学知识、正常和病理变化,可以诊断所检查的器官是否有病。
    The working principle of medical ultrasound examination is similar to that of sonar, that is, ultrasound is transmitted to human body through sound wave. When it encounters an interface in the body, it will be reflected and refracted, and may be absorbed and attenuated by human tissues. Because of the different shapes and structures of human tissues, they can reflect and refract ultrasonic waves and absorb them to varying degrees. In addition, combined with anatomical knowledge, normal and pathological changes, we can diagnose whether the organs examined are diseased or not.
    20赫兹以上的声波。声学的一个分支,研究超声波的产生、传播、接收和作用及其应用,称为超声波。有机械超声发生器(如气笛、汽笛、液体笛),电超声发生器由电磁感应和电磁作用原理制成,电声换能器由压电晶体和铁磁性材料的电致伸缩效应制成。
    Sound waves above 20 Hz. A branch of acoustics, which studies the generation, transmission, reception and application of ultrasound, is called ultrasound. There are mechanical ultrasonic generators (such as air flute, air flute, liquid flute). The electroacoustic generators are made of electromagnetic induction and electromagnetic interaction principle. The electroacoustic transducers are made of piezoelectric crystals and ferromagnetic materials by electrostrictive effect.
    焊接原理
    Welding Principle
    超声波塑料焊接原理是由发电机产生20KHz(或15KHz)的高压、高频信号,通过能量转换系统,将信号转换成高频机械振动,添加到塑料制品工件上。
    The principle of ultrasonic plastic welding is that the generator generates 20KHz (or 15KHz) high-voltage and high-frequency signals. Through the energy conversion system, the signals are converted into high-frequency mechanical vibration and added to the plastic parts.
    通过工件表面和分子间的摩擦,温度传递到界面上增加。当温度达到工件本身的熔点时,工件界面迅速熔化,然后填充界面之间的间隙。
    Temperature transfer to the interface increases through friction between the surface and molecules of the workpiece. When the temperature reaches the melting point of the workpiece itself, the workpiece interface melts rapidly, and then fills the gap between the interfaces.
    当振动停止时,工件在一定的压力下冷却成形,
    When the vibration stops, the workpiece is cooled and formed under certain pressure.
    实现了完美的焊接。
    Perfect welding has been achieved.
    新型15KHz超声波塑料焊接机对软PE、PP材料以及大直径、长长度塑料焊接件具有独特的焊接效果,可满足各种产品的需求。
    The new 15KHz ultrasonic plastic welding machine has unique welding effect on soft PE, PP materials and large diameter and long length plastic welding parts, which can meet the needs of various products.
