Automatic correcting belt conveyor

Abstract

The invention discloses an automatic correcting belt conveyor, comprising a main shaft, a workbench and a vacuum pull rod, wherein the vacuum pull rod is coaxially arranged in the main shaft, the lower end of the main shaft and the workbench are respectively and correspondingly provided with a suction head used for adsorbing an upper die sheet and a lower die sheet of a lens die, and the suction head comprises a suction head sleeve, a die sheet correcting locating rod, a locating rod limiting sleeve, a locating rod locking block, a locking block extrusion head and an elastic suction disc; andthe locking block extrusion head is fixedly arranged at the lower end of the vacuum pull rod, the locating rod locking block is sleeved outside the locking block extrusion head, the locating rod limiting sleeve is sleeved outside the locating rod locking block, and the suction head sleeve is fixedly sleeved outside the locating rod limiting sleeve. The automatic correcting belt conveyor can be used for automatically correcting the lens die cavity deviation caused by an uneven nonworking plane of the upper die sheet and the lower die sheet of the lens die, and after the lens die cavity deviation is corrected by a die sheet correcting locating rod, the defects, such as nonuniform product thicknesses, poor product smooth finish and the like caused by the uneven thickness of the nonworking plane of the lens die can be eliminated.

Description

technical field [0001] The invention relates to a tape machine, in particular to a tape machine capable of automatically correcting lens molds. Background technique [0002] Tape machine for resin lens molding, the upper suction head is fixed on the main shaft of the tape machine, and the lower suction head is set on the working table of the tape machine. When working, the upper suction head sucks the upper mold of the lens mold, and the lower suction head Suction the upper diaphragm of the lens mold, adjust the position relationship between the upper spindle and the worktable through the automatic control device to adjust the distance between the upper and lower dies, and then use the tape mechanism of the tape machine to stick tape around the die to form a resin lens die. [0003] Due to the deviation in the thickness of the working surface and the non-working surface of the diaphragm, there is a deviation in the thickness of the cavity between the upper and lower diaphrag...

AI Technical Summary

Problems solved by technology

[0003] Due to the deviation in the thickness of the working surface and the non-working surface of the diaphragm, there is a deviation in the thickness of the cavity between the upper and lower diaphragms after the mold is closed, resulting in defects such as uneven thickness of the edge of the product and poor surface finish of the product.
