Description

Device and method for extracting sealing paste of spectacle lens packaging bag

Technical Field

The invention relates to the technical field of sealing and attaching of spectacle lens packaging bags, in particular to a device and a method for extracting sealing and attaching of spectacle lens packaging bags.

Background

After cast molding, the ophthalmic lenses are typically contained in a package a, which, as shown in fig. 1, is composed of a pouch body 1 and a pouch mouth seal 2 integrally molded with the pouch body 1. Before the spectacle lens is put into the pocket 1, information such as parameters of the spectacle lens is printed on the pocket 1 for the seller or the like to recognize the information of the spectacle lens.

When the package bag a containing the spectacle lenses arrives at the vendor, the process of handling and transporting is required, and in this process, if the mouth of the package bag is not closed, the spectacle lenses are easy to fall out of the package bag, so in the prior art, it is common practice to fold the bag edge seal 2 along the mouth of the bag body 1, and insert the folded bag edge seal 2 into the bag body 1, thereby making the mouth of the bag body 1 form a closed state, and avoiding the spectacle lenses from falling out of the package bag.

In addition, merely inserting the pocket seal 2 into the pocket 1 does not completely ensure that the pocket seal 2 does not become dislodged from the pocket 1, for example, if the ophthalmic lens is subjected to a large vibratory force during shipping, the impact of the ophthalmic lens on the pocket seal 2 results in the pocket seal 2 being dislodged from the pocket 1. Therefore, the sealing paste is adopted to paste the bag mouth sealing edge 2 with the bag body 1 at present, and after the sealing paste is pasted, the sealing paste not only plays a role in firmly fixing the bag mouth sealing edge 2 with the bag body 1, but also plays a role similar to a seal, namely, only the sealing paste or the packaging bag is damaged, but also the lens can be taken out.

Then, the above-mentioned way of turning over the bag mouth sealing edge 2 and inserting the bag mouth sealing edge 2 into the bag body 1, and the way of pasting the bag mouth sealing edge 2 and the bag body 1 by adopting the sealing paste are all accomplished by the manual work at present, and the defect of manual operation is that the cost is high.
