Ultrasonic generator create ultrasonic (usually 40-140KHz), and produce high frequency librations through transducer, through amplitude rod and pass to chopper. When chopper touch with the down-lead and the welding object, in the force of pressure and librations, the welding metal surface scrub with each other, and the oxide film was destroyed, and occurred plastic distortion, and cause two clear metal surface touch closely, thus achieve the linking of atom distance, and finally form a firm metal bonding.
The down-lead material that ultrasonic welding used, in most cases, is aluminum wire and gold wire, copper also can be used for ultrasonic welding technique, at present, foreign countries have popularize copper welding in some range, our company will also dedicate in the researching of copper wire welding technology.

Automatic welding second point, and the two axes( welding head, displacement) move at the same time, so compared with U2000 in the past, the welding speed have much more improve, and greatly reduce the possibility of welding wire break.
The moving method is welding head moving;
Scientific speeding up and slowing down, to make the welding head runs more stably;
Can study and memory the moving distance of 80 wires, or 30 aiming height, radian and moving data, the welding wire has digital display, and go back and re-welding, amending function of the date of some wire, these function is very good to COB processing;
Excellent radian system, the radian can be adjusted at will, good consistency;
Because adapting steel beak positioning automatic detecting, and digital control adjust the height of first and second inspection, and the second inspection, it can easily handle component that has large height difference in first welding and second welding position;
Easy adjust, all parameters (ultrasonic power, time, welding pressure, aiming point, radian, span) are placed in the panel and you may adjust them by the tuning buttons;
Special first and second welding point pressure separate setting system, improve the stability and solderability of the first welding and second welding.
Because the above properties of the machine, besides digital tube and lattice plate, this machine is also suitable for the production of COB and medium and small power dynatron.

WL2040 Ultrasonic aluminum wire press welder
This machine is welding head displacing machine, it has same function and performance as WL2100 except it has no 80 wires span (or 30 wires height and span) memory function (detail function is subject to the user¡¯s manual)
Because the height every wires of LED digital tube, lattice plate is almost the same, so this machine is especially suitable for their production, meanwhile the price is cheaper than WL2100.
