Alignment mechanism for photovoltaic module cleaning device

An alignment mechanism for a photovoltaic module cleaning device comprises a six-degree-of-freedom motion control mechanism, a butt joint transmission mechanism and a posture detection system, the six-degree-of-freedom motion control mechanism is arranged on a vehicle body, the butt joint transmission mechanism is arranged on the six-degree-of-freedom motion control mechanism, and the posture detection system is connected with the six-degree-of-freedom motion control mechanism. According to the photovoltaic module cleaning device, automatic butt joint of the photovoltaic module cleaning device and a photovoltaic panel can be achieved, and then the photovoltaic module cleaning device can achieve cleaning work of front-back, high-low crossing and long-distance crossing row between photovoltaic modules. 一种用于光伏组件清扫装置的对准机构，包括六自由度运动控制机构、对接传动机构和姿态检测系统，六自由度运动控制机构设于车体上，对接传动机构设于六自由度运动控制机构上，姿态检测系统与六自由度运动控制机构相连。本发明能够实现光伏组件清扫装置与光伏面板的自动对接，进而使光伏组件清扫装置实现光伏组件间前后、高低跨越、长距离跨排的清洁工作。
