The invention discloses a workpiece loading and unloading trolley of a large optical coating machine, which comprises a frame, a driving wheel, a bearing wheel and a guide wheel are mounted on the outer side of the bottom of the frame, a loading and unloading trolley driving device is mounted at the center of the inner side of the bottom of the frame, a hydraulic oil cylinder is arranged at the top of the frame, and a workpiece lifting and rotating device is arranged at the upper end of the hydraulic oil cylinder. The lifting device is used for ascending or descending a workpiece to a required position, the lifting device adopts double hydraulic and double guide mechanisms, the double hydraulic lifting mechanisms are mounted on the left side and the right side of the rotating device, two sets of hydraulic lifting cylinders are simultaneously controlled by the same electromagnetic valve, two sets of guide mechanisms are mounted on the left side and the right side of the rear part respectively, and the guide mechanisms adopt linear bearing guide structures; the upper portion and the lower portion of the guide mechanism are fixed to the frame weldment, the linear bearing moves up and down along with the lifting mechanism, the stability of the lifting mechanism is ensured, the positioning and guiding system is arranged, the trolley can convey a bearing object in a high-precision mode, and therefore damage to a large-diameter optical element in the film coating process is reduced.

    本发明公开了一种大型光学镀膜机的工件装卸小车,包括车架,车架底部外侧安装有驱动轮、承载轮与导向轮,车架底部内侧中心处安装有装卸小车驱动装置,车架顶部设置有液压油缸,液压油缸上端设置有工件升降及旋转装置,升降装置用于将工件上升或下降到需要的位置,升降装置采用双液压双导向机构,双液压升降机构安装在旋转装置的左右两侧,由同一个电磁阀同时控制两套液压升降缸,后部左右各安装一套导向机构,导向机构采用线性轴承导向的结构,导向机构上下均固定在车架焊件上,线性轴承随升降机构上下运动,确保升降机构的平稳性,设置了定位与导向系统,使得小车可以进行高精度的运送承载物,从而减少镀膜过程中大口径光学元件的损坏。
