Ultrasonic welding machine (LC100-8)

This machine is a high-power ultrasonic single-machine welding equipment. This machine is a single-head split ultrasonic welding machine, and the ultrasonic generator is connected with the host by a cable, which avoids failures caused by vibration during work.

Basic principles and characteristics of ultrasonic welding:
The 20KHZ high-voltage and high-frequency electrical signal is generated by the ultrasonic generator, which is converted into mechanical oscillation of the same frequency through the piezoelectric inverse effect of the transducer, and acts on the mask in the form of audio longitudinal wave. The friction between the surface of the mask and the inner molecules increases the temperature transmitted to the interface. When the temperature reaches the melting point of the mask itself, the interface of the mask melts quickly, and then fills the gap between the interfaces. When the vibration stops, the workpiece is in a certain position at the same time. It is cooled and shaped under pressure to achieve perfect welding.

First, the main structure of the equipment and component brands
1. Transducer system: It adopts Japanese original chip transducer, Japanese ace steel horn, strong power, sturdy and wear-resistant, 20% higher than the equivalent domestic transducer system.
2. Pneumatic components: use the famous brand Taiwan Xuntuo large diameter cylinder & Phi; 63*75MM, five-way solenoid valve, running smoothly up and down, with good cushioning effect, eliminating the impact force of the welding head on the workpiece and the recoil force on the transducer, It is more conducive to welding more precise workpieces and effectively protecting piezoelectric ceramics. The machine is equipped with a precise fine-tuning mechanism, the fine-tuning distance can be as precise as 0.02mm, and there is an instrument indication. The height of the fuselage and the descending distance of the welding head have scale indications, with an accuracy of 1.0mm;
3. Frame: unique rectangular column design, higher mechanical strength, effectively avoiding the phenomenon of backwards during work, frame sheet metal, etc. are all processed by laser cutting machine, CNC shearing and bending machine to ensure the integrity The assembly of the machine is excellent, and the whole machine is all painted, with good adhesion, no falling off, and beautiful appearance.
4. Motion structure: The equipment adopts Taiwan famous brand linear slide rail, which has high precision (unmatched by traditional guide rods with linear bearings) and is strong and wear-resistant, making the welding head drop more smoothly, without deviation., more Conducive to welding more precise products.
5. Balance mechanism: The transducer assembly can be rotated at will, and the transducer assembly is equipped with a horizontal adjustable structure, and the workbench is equipped with an adjustable structure. The two debugging structures make the debugging of the mold more convenient and quick, easy to operate, easy to learn and understand.< br /> 6. Electrical system: a full set of high-quality imported components are assembled, the power amplifier part is improved design, and the amplifier components are added to share the load.
7. Reduce the temperature rise of the transistor and reduce the damage rate. There is no program control board design. The mechanical time dial switch is replaced by the Japanese OMRON time relay, and the time control is more accurate and reliable.
