Description The ultrasonic mask welding machine uses high-frequency vibration waves to be transmitted to the surfaces of two objects to be welded. Under pressure, the surfaces of the two objects are rubbed against each other to form a fusion between molecular layers. Some indentations can be seen everywhere on the mask, such as the edges, ear straps, and exhalation valve are all ultrasonically welded. As shown in the figure above, in the production process of masks, we can intuitively understand the welding of all-plastic nose bridge, welding after hemming, breathing valve welding, multi-layer seam welding, and ear band welding. These are actually all made by ultrasonic welding. Completed. When the ultrasonic wave acts on the thermoplastic plastic contact surface, it will produce tens of thousands of high-frequency vibrations per second. This kind of high-frequency vibration with a certain amplitude will transmit the ultrasonic energy to the welding area through the upper weldment. Because the welding area is two The acoustic resistance at the welding interface is large, so local high temperature will be generated. In addition, due to the poor thermal conductivity of the plastic, it cannot be distributed in time for a while, and it gathers in the welding area, which causes the contact surface of the two plastics to melt rapidly, and after a certain pressure is applied, it merges into one.   Ultrasonic welding process When the ultrasonic stops, let the pressure continue for a few seconds to make it solidify and shape, so that a solid molecular chain is formed to achieve the purpose of welding, and the welding strength can be close to the strength of the raw material. According to different welding methods, ultrasonic welding can be divided into embedded welding, riveting welding, spot welding and forming. Ultrasonic welding uses 15 kHz-50kHz high frequency vibration to melt and weld plastics. The upper and lower parts are compressed, and the ultrasonic vibration is transmitted to the joints of the upper and lower parts, causing alternating stress at the welding ribs, heating and melting the plastic through the friction between the molecules. The ultrasound stops, and the upper and lower parts continue to be pressed tightly until they are bonded together.

Advantages

Features:

Automatic frequency tracking: The system automatically tracks the resonance frequency of the welding horn. Compensate for detuning caused by heat and other reasons.

Digital frequency control: The operating frequency is digitally controlled by the microcontroller.

Digital amplitude setting: This feature allows users to set precise amplitudes according to application requirements, which provides a larger range and repeatability of settings than analog systems.

The amplitude can be adjusted in a large range: 1% ~ 100% continuously adjustable, which is different from the shortcomings of traditional generators that are difficult to work with low amplitude.

High-speed micro-controller: The internal micro-controller operates at a frequency of up to 168MHz, which can accurately and timely control the working conditions.

Control and sampling interval of 0.5 milliseconds: 2000 times of sampling and control for welding process per second.

Color touch screen display: Through the color screen and touch, friendly and easy-to-use human-computer interaction is realized, and the experience is better.

Coexistence of buttons and touch: common functions can provide better interaction through buttons. Among them, the buttons use silicone keys, which have a better feel.

Operating language: The user can select the applicable language in the start screen: currently only supports English and Chinese.

Slant start: Ultrasonic energy supply and welding horn start at the most suitable ascent speed to reduce the electromechanical pressure of the system.

Vibration after welding: The user can start the ultrasonic after the welding and pressure holding process is finished, and the workpiece sticking to the welding horn will be shaken off.

Welding quality monitoring: user-definable process alarm. When it is outside the range of user-defined defective products, the system will generate an alarm to remind the user.

Diagnosis at startup: During the startup process, the main components of the system are tested.

Timing frequency search: When starting up, the system conducts frequency search every one minute to update the resonance frequency of the welding horn. This is especially effective for a welding process that can affect the temperature of the welding horn. A change in the temperature of the welding horn will cause the resonance frequency to drift.
