In the ultrasonic welding production of plastic products, the misalignment of the upper and lower shells of the product is a very common problem in the fully automatic zipper machine. If the product is a fully automatic zipper machine, there will be misalignment, there are problems with the design of the product itself, there are also structural problems with ultrasonic jigs and fixtures, and of course there are also problems with ultrasonic machine debugging.

However, in general, the product itself has a good positioning function is the most important thing. When there is a misalignment, the method of modifying the ultrasonic fixture to improve the misalignment can only be said to be a "remedy" full-automatic zipper machine. Therefore, These issues must be considered thoroughly when designing a fully automatic zipper machine for plastic product structure. The good positioning of the liang automatic zipper machine should realize the following functions: 1. When a pressure is applied up and down, the product joint surface will not be deformed or misaligned, and the automatic zipper machine 2. When a lateral force is applied, the upper and lower plastics The joint surface will not shift. Usually the positioning is designed like this, straight mouth shape, convex-concave shape, double V groove shape, and the straight mouth is provided with a rib shape or a positioning pin structure.

In the actual production operation, if there is a wrong position of the fully automatic zipper after the product is ultrasonically welded, the following methods can be used to improve:

Fully automatic zipper machine

1. Fully automatic zipper machine to reduce welding pressure, because the product itself is unbearable due to excessive pressure, deformation occurs, and the interface will be misaligned;

2. Heighten the bottom mold so that it exceeds the joint surface by 2mm and use it on the fully automatic zipper machine. The fully automatic zipper machine deepens the depth of the bottom mold fixture to make the bottom mold firmly hold the product;

3. Use ultrasonic conduction welding to reduce the energy of ultrasonic transmission to the product;

4. Use the advanced ultrasonic welding mode to release the ultrasonic fully automatic zipper machine before touching the product to reduce the misalignment;

5. Using the fine adjustment limit function, the fully automatic zipper machine limits the welding depth of the ultrasonic handpiece;

6. Use high-power and high-amplitude ultrasonic equipment to complete the welding in the shortest possible time;

7. The misalignment of the ultrasonic upper and lower molds will also cause misalignment;

8. Modify plastic products and improve product positioning design; this is especially important. If the product has a good positioning design, it will save a lot of trouble in later use. Fully automatic zipper machine
