Ultrasonic welding machine can be divided into automatic welding machine, semi-automatic ultrasonic welding machine and manual welding machine according to the level of automation. Now let's know about the precautions for the use of ultrasonic welding machine and the types of applicable materials?
Precautions when using ultrasonic welding machine:
1. One end of the cable is connected to the output control cable connector on the vibration cylinder, and the other end is connected to the output control cable socket on the back of the electrical box and tightened.
2. Wipe the connection surface of the welding head, connect it to the transducer of the vibration cylinder, and lock it with a wrench. Note: When connecting, ensure that the two connecting surfaces between the welding head and the transducer are consistent and locked. Do not damage the machine because the connecting screw is too long or the sliding tooth cannot be locked, or the sound wave will not be transmitted smoothly.
3. When loading and unloading the welding head, the welding and transducer must be clamped with two wrenches respectively, and it is not allowed to lock or load and unload only part of them to avoid damage to the portable vibration generator.
4. Check that point 1 and point 2 are properly installed, insert the power cord socket into the external power socket, and pull the power switch. At this time, the power indicator is on.
5. Press the sound wave control switch gently, you can hear the welding head squeak when the sound wave is transmitted to the welding head, which indicates that the machine is working normally and can be put into use.
6. Do not dismantle the equipment without authorization when the machine is working abnormally. The supplier shall be notified or the equipment shall be sent to the manufacturer for inspection and maintenance.
Materials applicable to ultrasonic welding machine:
1. Acetal has high tensile strength, high compressive strength and good wear resistance. It is commonly used for welding, screws, bearings, drums, kitchenware, etc. Due to low grinding coefficient, ultrasonic welding requires high vibration amplitude and long welding time.
2. When ultrasonic vibration occurs to the ultrasonic welder for ester acid fabric, the material is easy to change color, the contact surface is not easy to absorb energy, and the welding is difficult.
3. Polypropylene has light weight, good insulation, high strength, heat resistance, chemical resistance, and can be made into rope mesh and other fabrics after drawing. Products include toys, suitcases, music enclosures, electrical insulators, food packaging, etc. Because of its low elastic coefficient, the material is easy to attenuate acoustic vibration and is difficult to weld.
4. Acrylonitrile butadiene styrene copolymer, light in weight, has both origination, rigidity and chemical resistance, and is widely used. The material has good thermal conductivity, especially suitable for ultrasonic welding.
5. Polystyrene has light specific gravity, strong corrosion resistance to water and chemicals, good stability, and good insulation. It is especially suitable for injection and extrusion molding, and is often used to manufacture toys, decorations, cup washing equipment, pans, lenses, floating wheels, etc. Due to its high elastic coefficient, it is suitable for ultrasonic welding.
6. Acrylic has high hardness, is resistant to heavy impact, is not affected by acid, has high optical clarity and good color, and is commonly used in automobile taillights, semaphores, medals, faucet handles, etc. Attenuation shall be paid attention to when it is used for ultrasonic welding machine.
