Inaccurate erection and uneven stress of ultrasonic horn

The phenomenon of inaccurate installation and uneven stress of ultrasonic horn clamp is generally divided into two cases:

1： It is generally believed that when ultrasonic welding machine is used, the precision of the product and mold surface can be contacted and the welding effect should be obtained. In fact, this is just a surface, because ultrasonic is a friction vibration, which can produce the phenomenon of sound wave propagation. If we only observe the stability of hardware (modular fixture), we must emphasize that the operation mode of ultrasonic welding is conducted sound wave while ignoring the integration mode of ultrasonic practice, The vibration friction is converted into heat energy and welded. At this time, the stability of the ultrasonic mold, the height of the product, the thickness and depth of the meat, the material and the welding wire and other factors must not be 100% under the same pressure. Therefore, when we inject the sample, we must consider the above factors to make the welding sample intact and reduce a large number of defective products.

2： The energy output from the upper die has its error value at each point, which is why some difficult dies need a long time to adjust the dies. The energy output from the upper die is different from the energy released from the whole surface. In general, the design of die welding wire is a very important factor. Whether the die welding is good depends on the design of die welding wire. On the other hand, it can rely on the horizontal screws of the ultrasonic welding machine itself. Or paste thin tape or aluminum foil to overcome these problems, and the accessories of ultrasonic welding machine itself are also very important. If the machine body is equipped with high-quality accessories, the performance and stability of the machine will be better.
