KYD mask machine manufacturers teach you to solve the unstable quality of welding machine products.
I tell you that this is determined by <1> machine output power; <2> HORN expansion ratio; <3> air pressure source; <4> voltage source
1. Machine output power + HORN expansion ratio = actual available power.
It can be seen that when ultrasonic welding is performed on a certain product, the output power of the machine is stronger from the viewpoint of planning and design, and the smaller than the expansion ratio of the HORN is designed.
On the contrary, the smaller the output power of the machine, the larger the expansion ratio of the HORN design. For example: 2200W ultrasonic fusion splicer, HORN expansion ratio is 2.5 times. When changing to a 3200W ultrasonic fusion splicer, the expansion ratio of HORN may be as long as 1.5 times. However, it does not emphasize that the output of the welding machine of the ultrasonic welding machine is large, but it is necessary to give the most suitable environmental operation when performing ultrasonic welding on a plastic product. In the meantime, it is necessary to consider the budget of the cost, the functional requirements of the product, and the welding standard. Then consider planning a complete working equipment and ultrasonic use skills.
2. After understanding the above-mentioned various key factors affecting the quality of ultrasonic welding, engineers should be familiar with and evaluate at the time of design.
(1). Product quality requirements functional standards; (2). Existing ultrasonic equipment;
3. Determine the shape and skills of the product design, such as supersonic waveguide fuse, product positioning and material. Since the available device resources are already fixed, it is necessary to use the product design techniques to match the available devices.
4. When we determine that there are no problems with human factors (1~2), quality instability will occur, which is a fact: the influence of air pressure and voltage. When we have been unable to stabilize the quality for many years, we also found that the quality standards that could not be reached during working hours were all off work, and when the voltage and pressure were stopped at the same time, the quality requirements were met unexpectedly. Therefore, it is also found that when a plurality of people or units use a common air pressure and voltage source, since the air compressor usually sets the air pressure inside the air storage cylinder to be lower than 2 to 4 kg, the air is automatically filled and filled. This is the cause of the error.
When the air pressure source reaches the welding machine through the pipeline, due to the fast welding speed, the air pressure of the first ultrasonic welding and the air pressure remaining in the pipeline for the second or third time also form an error, which will result in periodic or non-periodic quality changes.. The voltage is also due to the power company's output and millions of people have the opportunity to use it at the same time. The voltage drop generated at this time is not what we can control, so the pressure and voltage variables do make the energy output change, really cause changes in energy output. Of course it must be listed as a diagnostic item.
Countermeasures: If you want higher quality, such as the product needs less than 0.02m/m, or the weld line fusion condition needs to be more than 90%, the design engineer must be familiar with the ultrasonic welding equipment according to the planning order; 2. Decide Product function; 3. Familiar with the correspondence between ultrasonic and plastic welding; 4. Add voltage stabilizer as much as possible.
