The invention relates to a tray low-position lead screw lifter which comprises a tray lifting frame, two side supports, a guide mechanism and a lead screw lifting mechanism and further comprises a lifting positioning mechanism. The lifting positioning mechanism comprises positioning crosspieces which are distributed on the side brackets at intervals up and down, guide seats fixedly arranged on the tray lifting frame, positioning rods movably arranged on the guide seats and driving elements for driving the positioning rods to move to the positions above the positioning crosspieces on the corresponding layers, and the positioning rods are horizontally arranged; the positioning crosspiece and the driving element are arranged at the two ends of the positioning rod respectively, and the driving element is movably connected with the positioning rod. The tray lifting frame and the side support are locked through the lifting positioning mechanism, the problem that the tray lifting frame shakes up and down due to sudden change of the weight when a tray enters and leaves the lifter is prevented, and damage to the lead screw lifting mechanism is avoided; the lead screw lifting mechanism is matched with the guide mechanism, so that the lifting precision and stability of the lifter are greatly improved.

    本发明涉及一种托盘低位丝杆升降机,包括托盘提升架、两个侧支架、导向机构以及丝杆升降机构,还包括升降定位机构,升降定位机构包括上下间隔分布在侧支架上的定位横档、固定设置在托盘提升架上的导向座、活动设置在导向座上的定位杆以及驱动定位杆移动至对应层定位横档上方的驱动元件,定位杆呈水平设置,定位横档与驱动元件分设在定位杆的两端,且驱动元件与定位杆活动连接。本发明通过升降定位机构来锁定托盘提升架与侧支架,防止托盘在进入和离开升降机时由于重量的突然变化会导致托盘提升架发生上下的晃动的问题,避免对丝杆升降机构造成损坏;丝杆升降机构配合导向机构,大大提高了升降机的提升精度和稳定性。
