Electronic component pressing apparatus having rotating shaft angle adjusting device and testing and classifying device using thereof improving the angle positioning accuracy of the rotating shaft and the spatial arrangement of the apparatus
A rotating shaft angle adjusting device comprises a carrying rack, a rotating shaft, a drive source and a transmitting structure. The drive source is a motor arranged on the carrying rack in a Y direction. The rotating shaft is arranged on the carrier in a Z direction and located in a periphery of the drive source. The transmitting structure is provided with a worm gear and a worm wheel disposed between the rotating shaft and the drive source and cooperating with each other. The drive source drives the worm gear to rotate by using a motor having a small size. The worm gear in turn drives the worm wheel to rotate so that the worm wheel drives the rotating shaft to rotate for adjustment to a preset angle. When an external force is acting on the rotating shaft, the rotating shaft is prevented from randomly rotating by means of the meshing engagement of the worm gear and the worm wheel so as to have the rotating shaft positioned on an preset angle, thereby achieving the practical effects of improving the angle positioning accuracy of the rotating shaft and the spatial arrangement of the apparatus.一種轉軸角度調整機構,其包含承載架、轉軸、驅動源及傳動結構,該驅動源係於承載架設有呈Y方向配置之馬達,該轉軸係呈Z方向配置於承載架,並位於驅動源之周側,該傳動結構係於驅動源與轉軸之間設有相互配合之蝸桿及蝸輪,進而驅動源係以體積小之馬達驅動蝸桿旋轉,令蝸桿帶動蝸輪轉動,使蝸輪帶動轉軸旋轉調整至預設角度,當轉軸承受外力時,利用蝸桿與蝸輪之相互嚙合卡掣定位,以防止轉軸任意偏轉,使轉軸確實定位於預設角度,達到提升轉軸角度定位精準性及利於機構空間配置之實用效益。30‧‧‧角度調整機構31‧‧‧承載架311‧‧‧底板312‧‧‧支柱313‧‧‧頂板32‧‧‧驅動源321‧‧‧馬達33‧‧‧轉軸331‧‧‧載板34‧‧‧傳動結構341‧‧‧蝸桿342‧‧‧蝸輪35‧‧‧彈性件
