ABSTRACT:
An automatic corrector for electronic parts queuing machines includes an automatic correction apparatus disposed below conveyance rails, and an electronic eye device disposed in front of the automatic correction apparatus. The automatic correction apparatus includes an elevating device, a linkage device, a drive device, and a correction device. The drive device is used to drive the linkage device, which in turn brings the elevating device to perform elevating and lowering motions. The correction device includes at least one to three correction grooves that are provided on the elevating device. The correction grooves can be oblong V-shaped, oblong M-shaped, or triangular V-shaped. When any of the electronic parts on the conveyance rails tilts forwardly or rearwardly, it can be detected by the electronic eye device. The electronic eye device hence causes the conveyance rails to stop and further cause the automatic correction apparatus to elevate to guide the tilted electronic part(s) into the correction grooves. After the automatic correction apparatus has lowered, the electronic parts are returned to the conveyance rails, which continue to advance. The automatic corrector eliminates manual correction when trouble occurs so as to increase production capacity and reduce production costs.
