Description

[Technical Field]

[0001] This invention belongs to the technical field of lens production equipment, and in particular relates to an automatic lens loading and unloading device for a molding machine. [Background Technology]

[0002] In the manufacturing process of optical lenses, there is a molding process that involves placing a glass preform into a lens mold for molding. After molding, the finished lens is removed. Currently, the industry generally uses manual labor to remove the upper mold core, place the preform inside, and then manually close the mold before placing it into the molding machine inlet. This process is time-consuming, labor-intensive, highly dependent on manual labor, and inefficient.

[0003] Therefore, the existing single-cavity automatic loader completes the loading and unloading operations of pre-shaped body input and finished lens output. It uses a mold-separating cylinder to remove the upper mold core, a finished lens suction pen to remove the finished lens and place it on the receiving tray, and then uses a pre-shaped body suction pen to remove the glass pre-shaped body from the raw material tray and put it into the mold. After the mold-separating cylinder closes the mold, the mold-grabbing cylinder puts it into the mold press inlet. However, due to the long stroke of the finished lens suction pen to remove the shaped lens and place it on the receiving tray, and the long stroke of the pre-shaped body suction pen to remove the glass pre-shaped body from the raw material tray and put it into the mold, the loading and unloading efficiency is low. [Summary of the Invention]

In use, the conveying mechanism transports the lens mold. First, the pick-and-place mechanism picks up and places the finished lenses from the lens mold to the finished lens unloading mechanism. Then, the finished lenses from the finished lens unloading mechanism are placed in the finished lens placement area. The pick-and-place mechanism and the finished lens unloading mechanism can work independently and synchronously, greatly improving the unloading efficiency of finished lenses. Similarly, the pre-shaped lenses from the pre-shaped lens placement area are first placed in the pre-shaped lens loading mechanism, and then the pick-and-place mechanism picks them up and places them into the lens mold.
