In the process of using the mask machine, it is inevitable that there will be many problems, so today I will tell you about the common problems of the mask machine in the schedule operation:
1. Process misunderstanding of welding workpiece mask machine
The welding line of the mask machine should be a point or a line and the distance of transmission should be compatible with the ultrasonic welding method. Some people think that the mask machine only needs to be plastic material, no matter how the joint surface can be welded, this is a mistake. When the instant energy occurs, the larger the joint area, the more severe the energy loosening, the worse the welding effect, or even the welding. Other ultrasonic waves propagate longitudinally, and the energy loss is proportional to the distance. The long distance should be controlled within 7.5 cm. The welding line should be controlled between 0.3-0.8mm for the best condition. The wall thickness of the workpiece should not be less than 2mm, otherwise it cannot be welded well, especially for products that require water and air tightness.
2. Misunderstanding of workpiece material
The ultrasonic welding machine of the mask machine has requirements for the material of the workpiece to be welded. Not all materials can be welded. Some people think that any material can be welded. This is a big misunderstanding. Some materials can be welded excellently, and some are basic. Welding, some are not fused. The melting point of the same material is the same, and it can be welded in principle.
3. Misunderstanding of ultrasonic output power
The ultrasonic output power is the same as the diameter and thickness of the piezoelectric ceramic sheet, the material, the planning process resolution, the transducer is finalized, and the power is finalized. Measuring the output energy is a messy process. It is not that the larger the transducer, the more power tubes used in the circuit, the greater the output energy. Its appropriate and messy amplitude measuring instrument can accurately measure its amplitude, because most users do not know the common sense of supershen wave, plus The misleading of the sales staff gives consumers a wrong understanding that the amount of electrical energy consumption does not reflect the size of the output ultrasonic power. If the longitudinal energy is low, but the current consumption is large, it can only clarify that the power of the equipment is low, but the power is not large. Say.
