文内介绍的程控器是采用步进顺控原理,控制四个自由度的机械手,带动焊钳完成对汽车门上梁的焊接。控制电路中采用了 HTL 高抗干扰数字集成电路,加入光电隔离、集成稳压器件、积分网路、吸收回路等措施,提高了程控器的抗干扰能力,当电网电压波动为± %时,系统仍能正常工作。 Introduced in the text programmer is the use of step-by-step control principle, the control of four degrees of freedom manipulator, driven welding clamp to complete the welding of the car door beam. The control circuit adopts HTL high anti-jamming digital integrated circuit, adding optical isolation, integrated voltage regulator, integral network, absorption circuit and other measures to improve the anti-interference capability of the programmable controller. When the voltage fluctuation of the power grid is ±%, the system Still working.
