Ultrasonic spot welding machines are divided into: ultrasonic spot welding machine, ultrasonic plastic spot welding machine, riveting spot welding machine, ultrasonic metal welding machine, ultrasonic metal spot welding machine, ultrasonic welding machine, aluminum nickel welding machine, polymer battery positive spot welding machine , Lithium battery negative electrode spot welder, aluminum to nickel spot welder, amorphous silicon spot welder, etc.

The welding principle of ultrasonic spot welder is to convert 50/60 Hz current into 15, 20, 30 or 40 kHz electric energy through an ultrasonic generator. The converted high-frequency electric energy is again converted into mechanical motion of the same frequency through the transducer, and then the mechanical motion is transmitted to the welding head through a set of amplitude modulator devices that can change the amplitude. The welding head transfers the received vibration energy to the joint of the workpiece to be welded. In this area, the vibration energy is converted into heat energy through friction to melt the plastic. The short-term pressure maintained on the workpiece after the vibration stops causes the two weldments to solidify into one body in a molecular link. Generally, the welding time is less than 1 second, and the obtained welding strength is comparable to that of the main body. Ultrasound can be used not only to weld hard thermoplastics, but also to process fabrics and films. The main components of an ultrasonic welding system include ultrasonic generator, transducer/amplitude modulator/welding head triple group, mold and frame.

Ultrasonic spot welding machine can be used for butt welding of thermoplastics, and the welding head can also be replaced according to customer needs. It can be used for processing processes such as riveting, spot welding, embedding, and cutting. Compared with other traditional processes (such as gluing, electric ironing or screw Fastening, etc.), has significant advantages such as high production efficiency, good welding quality, environmental protection and energy saving. Ultrasonic spot welding machine adopts imported piezoelectric ceramic vibration crystal, high efficiency and long life; original normal temperature cycle self-cooling ultrasonic generator, the lowest failure rate in the industry; aluminum alloy casting overall frame to ensure the rigidity of the machine body; gear rack lifting Mechanism, easy operation and precise positioning; both automatic and manual operation modes, convenient for debugging; optional cabinet workbench designed according to ergonomic principles; with automatic counter, and reserved foot switch interface. Ultrasonic spot welding machine is mainly used for the positioning and bearing of the workpiece. The metal tooling or resin casting tooling that is engraved and polished has the function of protecting the surface of the workpiece from scratches. In addition, the tooling can be made into automatic tooling and welding machine linkage. , To improve the operating mode or increase production efficiency. Ultrasonic spot welding machine can also be used for welding, riveting, spot welding of thermoplastic products, as well as the inlay and edge pressing process between metal parts and plastic parts. It eliminates the backward process of pasting with chemical organic melting point agents and has low energy consumption. , High efficiency, no deformation, no pollution, firm welding, convenient operation, etc. The product adopts advanced circuit, program control, pneumatic transmission, automatic overcurrent protection, and safe operation protection circuit. The circuit adopts a circuit board plug-in structure, which is convenient for maintenance and replacement. A new 15KHz ultrasonic plastic welding machine with an electronic delay welding device is also designed. Welding of softer PE and PP materials, as well as plastic weldments with large diameters and long lengths, have their unique advantages, which can meet the needs of various products and contribute to the improvement of production efficiency and product quality for users.
