Application examples of Ultrasonic Wire Bonder Spot Welder
Nickel mesh and nickel sheet of nickel hydrogen battery are mutually fused. Copper foil and nickel sheet of lithium battery and polymer battery are mutually melted, and aluminum foil and aluminum sheet are mutually melted. The wires are fused with each other, forming one and several wires, and the harness is welded. The wires are fused with various electronic components, contacts and connectors. The mutual melting of large heat sinks, heat exchange fins and honeycomb cores of various household appliances and automotive products. High current contacts such as electronic component leads, relays, electromagnetic switches, fuse free switches, and mutual melting of dissimilar metal chips. The tail sealing and cutting of metal pipe can be water tight and air tight.

FAQ
Q: What should I do if the ultrasonic wire bonder spot welder welding effect is bad?
A: Poor ultrasonic welding refers to:
1. The upper and lower covers of the plastic parts are not fully welded, resulting in false welding, weak welding, etc.;
2. The surface of the welded plastic part is scratched, the appearance surface is damaged, etc.;
3. Dislocation of the upper and lower covers of the plastic parts, etc.
To solve the above problems, we need to pay attention to:
1. Adjust the drop pressure. The drop pressure has a very large relationship with the ultrasonic welding effect of plastic products. Generally, plastic products generate heat by ultrasonic vibration and friction to achieve the welding effect. We do not rely on pressure to achieve the welding effect, but pressure only plays a role. Therefore, the size of the pressure is very important, you must pay attention!
2. The surface of the product is pasted with a protective film or a protective film is used for ultrasonic welding. Ultrasonic welding requirements of each customer are very different. Some products are not appearance surfaces. Ultrasonic welding needs to be firm, and there is no need to pay attention to appearance. But in most cases, the ultrasonic welding requirements of products are relatively high, such as U disks, mobile phone batteries, SD cards, mouse receivers, etc. How to solve the problem of product surface crushing and scratching has always plagued the adjustment of ultrasonic welding machines. To solve this problem, we need to start from many aspects, such as making the ultrasonic mold fit the product very well, and whether the ultrasonic mold is smooth or not.
3. Adjust the ultrasonic welding time. The length of the ultrasonic welding time directly affects the quality of the products being ultrasonically welded. If the time is too long, the surface of the product will be embossed, and if the time is too short, the welding will be weak, false welding, and easy to fall off. Only adjust to the appropriate time according to the specific product needs is a good choice.
4. Product positioning mechanism. When designing an ultrasonic welding plastic product, it is necessary to design the alignment mechanism of the upper and lower plastic parts of the product according to the characteristics of the product to avoid misalignment during ultrasonic welding.
Applications
Ultrasonic wire bonder spot welder is used for wire harness welding on wires, cables and connectors in electrical appliances, electronics, automobiles, motorcycles, electric vehicles, and other industries. Specifically applicable to connector wiring harness, airbag wiring harness, etc. The advantages of ultrasonic wire-beam welding are no flux is required, and the welded joint is a fused alloy layer, stable chemical properties, good electrical conductivity, and the resistance system is basically the same as the original coefficient of the material that with no spatter, bright solder joints, no terminals cracking, copper is not exposed in the plating layer.
