The invention relates to the technical field of circuit board production equipment, in particular to a PCB transfer trolley. The PCB transfer trolley is composed of universal wheels, a base, spiral stand columns, a lower layer plate, a middle plate, an upper layer plate, a height adjusting assembly and a toothed belt. The height adjusting assembly comprises a nut and a pressing ring. The toothed belt drives the nut to rotate on the spiral stand column, the nut is restrained by the spiral stand column to rotate and move up and down along the spiral stand column at the same time, the middle plate is pushed to move up and down, and the aim of adjusting the distance between the plates is achieved. Meanwhile, the nuts are driven by the belt to synchronously rotate on the spiral stand column, so the lifting speeds of the nuts are consistent, and the middle plate is always in a horizontal state. The device is simple in principle, ingenious and reasonable in structure and convenient to use, and has certain economic benefits.

    本发明涉及一种电路板生产设备技术领域,特别是一种PCB板转运车。该PCB线路板转运车由以下零部件组成:万向轮、底座、螺旋立柱、下层板、中间板、上层板、调高组件、齿形带。其中调高组件包括螺母和压环。通过齿形带带动螺母在螺旋立柱上转动,受螺旋立柱的约束螺母在转动的同时沿螺旋立柱上下运动,推动中间板上下移动,达到调节板间距的目的。同时通过皮带驱动各螺母在螺旋立柱上同步转动,使得各螺母升降速度一致,中间板始终处于水平状态。本发明原理简单,结构巧妙合理,使用方便,具有一定的经济效益。
