振动焊接系统
摘要：
本发明公开一种振动焊接系统。一种振动焊接系统具有耦合到第一工件支架以便实现第一工件支架相对于第二工件的往复移动的一对电磁体，和耦合到电磁体以便连续地激励和去激励彼此有相位差的电磁体来实现第一工件支架的往复移动的电气驱动系统。该驱动系统包括DC电流源；多个可控制的电子开关装置，其用于可控地将所述源耦合到每一个所述电磁体并且从每一个所述电磁体去耦合所述源；电流传感器，其耦合到所述电磁体并且产生表示供应给所述电磁体的电流的信号；以及控制电路，其耦合到所述电子开关装置并且接收由所述电流传感器产生的用于将所述开关装置接通和关断的信号，以便控制所述电磁体的激励和去激励，从而实现所述第一工件支架的往复移动。
摘要（英）：

A vibration welding system has a pair of electromagnets coupled to a first workpiece support for effecting reciprocating movement of the first workpiece support relative to a second workpiece support, and an electrical drive system coupled to the electromagnets for successively energizing and de-energizing the electromagnets out of phase with each other to effect the reciprocating movement of the first workpiece support. The drive system includes a source of DC current; multiple controllable electronic switching devices for controllably coupling the source to, and de-coupling the source from, each of the electromagnets; current sensors coupled to the electromagnets and producing signals representing the currents supplied to the electromagnets; and control circuitry coupled to the electronic switching devices and receiving the signals produced by the current sensors for turning the switching devices on and off to control the energizing and de-energizing of the electromagnets to effect reciprocating movement of the first workpiece support.
