Abstract
The present invention provides injection moulding process in a kind of touch screen glass molds, it is characterised in that comprise the following steps：The first step, touches panel glass print glue；Second step, print glue drying；3rd step, touch screen glass in-mould injection；4th step, strip.In 3rd step, touch screen is put into into injection mould, realizes that PUR is combined with touch screen using mould and plastic material temperature.The beneficial effect of the method is that by the rapid shaping of screen, and yields is high, seamless.Meanwhile, the method for in-mould injection improves the automaticity of screen assembling, instead of traditional dispensing, improves the quality stability of product, it is possible to decrease by the error brought manually is operated, provide the support in Technology for the narrow side of mobile phone.
Description
Technical field
The present invention relates to a kind of touch panel glass assembling field, injection moulding process in specifically a kind of touch screen glass molds.
Background technology
As the continuous improvement of level of consumption, requirement of the consumer to electronic product are also increasingly improved, its function is not concerned only with, its outward appearance and design are also more paid attention to.Therefore the appearance details of electronic product just become a key issue that can not be ignored.Especially mobile phone industry, mobile phone screen presents increasing development trend, therefore handset size also increases therewith, but excessive handset size can affect the gripping sense of user, Consumer's Experience is poor, therefore can either realize that mobile phone screen is big, while the method for avoiding handset size excessive again is exactly the narrow side of mobile phone.At present, the method that screen assembling is adopted is mainly dotting glue method, and dotting glue method has that efficiency is low, and screen gap is big, and yields is low, tool complexity high cost, the shortcomings such as easy light leak of screen edge.Separately, in-mould injection industry is presently mainly non-metal kind only decorative appearance based on five metals in-mould injection（IMD,IML）Technique, it is temporarily blank for functional part in-mould injection.
The content of the invention
To solve above-mentioned the deficiencies in the prior art, the present invention provides injection moulding process in a kind of touch screen glass molds, and the method can replace traditional dispensing packaging technology, realize the rapid shaping of screen, and yields is high, seamless；The blank of functional parts in-mould injection has been filled up simultaneously.
The present invention provides injection moulding process in a kind of touch screen glass molds, comprises the following steps：The first step, touches panel glass print glue；Second step, print glue drying；3rd step, touch screen glass in-mould injection；4th step, strip.
Further, injection moulding process in a kind of touch screen glass molds, in the first step, the material for touching panel glass is glass, the type of glue of the print glue is PUR, and in the second step, the method for printing glue drying is 75～85 DEG C of dryings 10～15 minutes in hot air drier；In 3rd step, touch screen is put into injection mould by touch screen in-mould injection, realizes that PUR is combined with touch screen using mould and plastic material temperature.
The present invention provides injection moulding process in a kind of touch screen glass molds, comprises the following steps：
The first step, single-layer touch panel glass print glue or touch panel glass print glue laminating safety glass, the material of the touch panel glass is glass, and the type of the glue of the print glue is PUR.
Second step, print glue drying, the method for printing glue drying are 75～85 DEG C of dryings 10～15 minutes in hot air drier.
Touch screen is put into injection mould by the 3rd step, touch screen glass in-mould injection, realizes that PUR is combined with touch screen using mould and plastic material temperature.
4th step, strip.
Further, the material of the touch screen can also be TFT, OLED, NOVA, AMOLED, Super AMOLED, Super AMED Plus, IPS, SLCD, ASV.
The present invention provides injection moulding process in a kind of touch screen glass molds, and the beneficial effect of the method is that by the rapid shaping of screen, and yields is high, seamless.Simultaneously, the method of in-mould injection improves the automaticity of screen assembling, instead of traditional dispensing, improve the quality stability of product, can reduce, by the error brought manually is operated, the support in Technology being provided for the narrow side of mobile phone, the method can replace traditional dispensing packaging technology, the rapid shaping of screen is realized, yields is high, seamless；The blank of functional parts in-mould injection has been filled up simultaneously.
Specific embodiment
To make the purpose of the present invention, technical scheme and effect clearer, clear and definite, the present invention is described in more detail below.It should be appreciated that described herein be embodied as example only to explain the present invention, it is not intended to limit the present invention.
Embodiment 1：
, by printing glue laminating, glue is optical refractory glue for TFT touch screen glass and safety glass, and safety glass border is all higher than the border of TFT touch screen, and the safety glass and touch screen after laminating is moved in hot air drier 75 DEG C of dryings 15 minutes then；The touch screen fitted completely and safety glass are carried out into in-mould injection, touch screen is put into injection mould, realizes that PUR is combined with touch screen using mould and plastic material temperature by touch screen in-mould injection.
By front mould prefabricated two location holes are positioned to touch screen, screen adsorption preventing is fallen off during matched moulds by getter device, it is put into the touch screen of 5 inch, absorption matched moulds, it is then injected into plastic cement, plastic cement proportioning is PC+10%GF, two-part pressurize, respectively first paragraph pressure is 1200kgf, dwell time 1.5s；Second segment pressure is 500kgf, dwell time 0.5s, is then cooled down, and cool time is 8s, and the product after injection is taken out after die sinking.
By the touch screen after the completion of injection and safety glass strip.
The present embodiment provides injection moulding process in a kind of touch screen glass molds, and the beneficial effect of the method is that by the rapid shaping of screen, and yields is high, seamless.Simultaneously, the method of in-mould injection improves the automaticity of screen assembling, instead of traditional dispensing, improve the quality stability of product, can reduce, by the error brought manually is operated, the support in Technology being provided for the narrow side of mobile phone, the method can replace traditional dispensing packaging technology, the rapid shaping of screen is realized, yields is high, seamless；The blank of functional parts in-mould injection has been filled up simultaneously.
Below the present invention is described in detail, the above, only the preferred embodiments of the invention is when can not limit the scope of the present invention, i.e., all according to the made impartial change of the application scope and modification, all still should belong in covering scope of the present invention.
