Description

Technical Field

[0001] The invention relates to the technical field of eyeglass frame processing equipment, in particular to a full-automatic eyeglass foot pin-inserting machine. Background Art

[0002] The temple of the glasses is composed of a plastic temple part and a temple pin. In order to allow the temple to be further bent during use and thus extend the service life of the glasses frame, a temple pin is usually inserted into the end of the plastic temple part. The pin, also known as the copper core, is an indispensable metal for making the temple wire of the plate. However, the existing glasses pen pin insertion machine is semi-automatic, and the plastic temple part and the pin need to be placed manually inside the machine to realize the core insertion action. This semi-manual positioning method is not only inefficient, but also the product quality is not controlled, and the positioning accuracy cannot be guaranteed, resulting in a high scrap rate and a certain degree of waste.

[0003] In the patent technology of invention CN201510673024.8 entitled "Fully Automatic Eyeglass Core Insertion Machine" disclosed in the Chinese patent document, a method is disclosed in which the eyeglass pin plastic parts and the insertion pins are placed in an eyeglass pin plastic part feeding device and an insertion pin feeding device respectively, and the eyeglass pin plastic part feeding device conveys the eyeglass pin plastic parts to a rotating clamping mold on a rotating table through the eyeglass pin plastic part conveying device, and automatic feeding is realized by using the eyeglass pin plastic part feeding device and the insertion pin feeding device. However, only three workstations are set on the rotating body of the equipment, and the three workstations can only perform the pin insertion process of one eyeglass frame in turn at a time, with low processing efficiency. Completing the insertion of one eyeglass pin at a time greatly reduces the qualified rate of the finished eyeglass frames for eyes with symmetrical structures, and is prone to asymmetric installation and mismatch of the left and right structures. Moreover, the whole set of equipment is composed of a plurality of parts and docking stations, and the connections between them are not tight and the processing is difficult.

Based on the above, how to provide a eyeglass pin insertion machine to reduce the difficulty of the production process, improve the product qualified rate, and improve production efficiency has become a technical problem that technical personnel in this field need to solve urgently.
