Robot Ultrasonic Welding Widely Used in Automotive Industry
Since the weld is directly fused by two plastic parts, its characteristics are unchanged and the consistency is good.
It can accurately control the heat output. Under the correct process range, the welded weld has high strength and beautiful appearance. The welding deformation is small.
No need to add any binder, filler or solvent during welding, and the noise is small and does not pollute the environment.
Using high frequency power supply, the operation is safe.
Fast welding speed and high production efficiency, which can be used for the production of large quantities of products.
It is not necessary to carry out any surface treatment on the surface of the weldment before welding, the operation is simple, and the labor intensity of the worker is small.
What about the uneven stress of ultrasonic metal welding machine?
Generally When ultrasonic operation, the product and the mold surface as long as the contact accuracy can be obtained by the ultrasonic welding machine welding effect, in fact, this is only the surface view, since the ultrasonic vibration, it will produce the sound wave conduction phenomenon.
On the other hand, the energy output from the upper mold (H er n ) has its own error value at each point, and not all the energy emitted from the entire surface is the same. On the whole, there is bound to be a difference in the degree of welding of the product welding line. Therefore, it is necessary to make corrections. How to correct it is to overcome the problem by relying on the horizontal screws of the ultrasonic welding machine itself, or by sticking thinner tape or aluminum foil.
What is the Absorption characteristics of ultrasonic?
As sound waves propagate through various materials, the intensity gradually weakens as the propagation interval increases, because the material absorbs its energy. Regarding the same substance, the higher the frequency of sound waves, the stronger the absorption. Regarding a sound wave with a certain frequency, the absorption is most severe when it propagates in a gas, the absorption is weak when it propagates in a liquid, and the absorption is minimal when it propagates in a solid.
