【摘要】 本文介绍了超声波塑料焊机的一种新型的能量控制模式，该模式利用微机控制系统检测输入换能器的有用电功率，并以此柔性控制焊接时间，从而使焊接质量对气压、电压等波动的敏感性变弱，质量的稳定性提高。更多还原

【Abstract】 A new kind of energy-controlled mode for ultrasonic plastic welder is reportedin the paper. Using this mode the microcomputer control system contro s the weldingtime corresponding to the useful power signal which is sampled through the inputingtransdueer.In this way the weld quality is insensitive to air pressurefluctuation, voltage flutuation,etc. Therefore quality stability is increased.更多还原
