Application field of ultrasonic welding machine
Ultrasonic welding technology is widely used in the field of plastic welding. This article will take you to understand the most commonly used packaging materials, using ultrasonic welding technology for welding.
The most common materials for sealing packaging using ultrasonic technology are usually thermoplastic coatings, such as medicine capsules, plastic bags, milk and other beverage boxes. These products use ultrasonic welding technology to achieve high-speed mass production while ensuring the quality of product packaging. Intelligent welding machines can meet our individual needs for products.
Pets In PET applications, common molded products are in the form of blister packaging, such as toothbrush outer packaging.
The use of ultrasonic technology enables products to be welded quickly while retaining features such as product openings and anti-counterfeiting labels. Flexible beverage packaging Ultrasonic welding technology is particularly suitable for packaging plastic-coated cardboard materials, such as milk cartons and apple cider vinegar cartons.
Although the humidity of these products is high, ultrasonic technology can still seal the weld seam. The aluminum film has no effect on the welding effect, the sealing time is short, the output is high, and the sealing quality is good. The product can be realized without frequently changing the welding parameters. Is consistent. Film packaging The outer packaging of instant noodle seasoning packaging and bagged instant noodles are all in the form of film packaging.
When film packaging, ultrasonic can easily separate the residual product in the weld, thus ensuring the seal.
Top-box packaging The most common type of top-box packaging is barreled instant noodle lids. This form of packaging has high requirements on welding technology, because the welding contact surface is small and requires precise positioning. This is also one of the important applications of ultrasonic solutions.
Ultrasonic energy can be accurately positioned by vacuum and can be completed quickly without heating the mold. Ultrasonic is the latest industrial welding technology.
It not only has high welding accuracy, high product density, but also stable stability. It can be welded flexibly according to the needs and characteristics of customers' products.
Method of welding irregular workpiece with ultrasonic welding machine
At present, there are many ultrasonic welding machines with a high degree of automation on the market. The mechanical arms on the welding equipment are as flexible as human hands and can accurately control workpieces with relatively standard sizes and specifications. In the manufacturing industry, there are many irregular-sized workpieces, which rely on manual labor during welding. In order to reduce this dependence, it is necessary to find a way to weld irregular workpieces with an ultrasonic welding machine in order to better release human hands.
According to people's research on ultrasonic welding machines, it is found that the main factor hindering the automation of welding of irregular workpieces is the fixture. Through more reasonable design of furniture, the accuracy of the equipment's loading and unloading of irregular workpieces can be improved. Considering the stability and accuracy of welding, three points need to be paid attention to when designing fixtures: First, use materials with strong wear resistance, such as metals; Second, design the structure and size of the fixture reasonably according to the shape of the workpiece to ensure that the fixture is not It will destroy the quality of the workpiece; third, it is necessary to ensure that the fixture can withstand a certain amount of ultrasonic energy, and will not be affected by the energy generated by the ultrasonic welding machine, resulting in the inability to clamp the workpiece.
For some workpieces with particularly complex structures, it may not be possible to develop suitable fixtures, so can't the ultrasonic welding machine be used for welding? In fact, as long as people do not emphasize automatic welding, only use the welding machine for welding work, without loading and unloading operations , But use manual loading and unloading. It is hoped that with the continuous development of AI technology, visual recognition technology and information control technology, people can develop more intelligent robotic arms, which can further improve the automation performance of ultrasonic welding machines and truly liberate human hands.
