Description

A kind of full-automatic overlay film assembly line of 3D bend glass

Technical field

The utility model relates to 3D bend glass field, in particular to the full-automatic overlay film assembly line of a kind of 3D bend glass and Its film covering method.

Background technique

The glass cover-plate used on smart terminal product display on existing market can be divided into: 2D glass, 2.5D glass and 3D bend glass, wherein the pure flat surface glass of 2D glass, that is, common, without any cambered design；It is flat that 2.5D glass is then intermediate Face design, edge use cambered design；Then intermediate and marginal portion may be designed to curved arc to 3D bend glass.3D is bent Surface glass mainly be bent using hot-bending machine, can achieve higher crooked radian, some physics of 3D bend glass Characteristic is substantially better than 2D and 2.5D glass.3D bend glass has frivolous, transparent cleaning, anti-fingerprint, anti-dazzle, hard, scratch resistance Wound, the advantages that weatherability is good, can not only promote the novel appearance of smart terminal product, can also bring outstanding touch-control hand Sense brings preferably display and touch experience.

The technique of 3D bend glass production at present mainly has: sawing sheet, CNC, grinding and polishing, baking, plated film, hot bending etc., In one of coating technique is also connect after hot bending process, i.e., the 3D bend glass bumps two sides (also referred to as positive and negative two after hot bending Face) protective film is enclosed, this technique is more crucial, restricts the height of yields to a certain extent.In general, in 3D curved surface glass In the coating technique of glass, the processes such as experience feeding-transfer-front overlay film-transfer overturning-back side overlay film-blanking are generally required, and In this set process, concave surface overlay film and convex surface coating processes are the most key, directly affect the overlay film efficiency and overlay film matter of 3D glass Amount.

In existing 3D bend glass overlay film assembly line, there are the following problems: firstly, the degree of automation is low, needing The step of human assistance, is more, thus leads to overlay film inefficiency, workpiece during the circulations such as feeding, overlay film, blanking vulnerable to To pollution and damage；Secondly, common processing mode is that concave surface overlay film step and convex surface overlay film step are divided into two in the market Line carries out operation, this results in docking between two lines and collaborative e-commerce low, so as to cause overlay film inefficiency, or even delay machine occurs Accident, directly affect the overlay film efficiency and compound film quality of 3D glass；Again, to the fixed unstable of 3D bend glass, cause to cover Play phenomenon all around can occur for 3D bend glass in membrane process, so that there are more with glass surface for protective film after overlay film Stomata influences compound film quality；In addition, the concave and convex surfaces supporting degree to 3D bend glass is insufficient, on the one hand can make in overlay film In the process, 3D bend glass bursts, and the convex surface that other hand will lead to 3D bend glass is deformed or scratch；Again The step of secondary, supply the degree of automation of protective film is low, needs human assistance is more, cannot efficiently supply protective film, can not Release paper is recycled, cavity plate overlay film inefficiency is thus caused；Again, since the concave surface of 3D bend glass is to lower recess one Depthkeeping degree, convex surface raise upward certain altitude again, thereby result in the cooperation inhaled between diaphragm plate and press mold component and be easy to cause mutually Interference, thereby result in press mold component to protective film suppress it is insufficient, cause compound film quality poor, between protective film and 3D bend glass It is easy there are bubble, it is easy to fall off so as to cause protective film, do not have the effect protected to 3D bend glass.

In view of this, it is really necessary to develop a kind of full-automatic overlay film assembly line of 3D bend glass and its film covering method, to It solves the above problems.
