Abstract

The invention discloses a method for manufacturing a waterproof anti-shock mobile phone touch screen. The front and reverse sides of a glass panel are printed with strippable protection layers in advance, then the lateral surface of the glass panel is coated with a bonding agent to form a bonding layer, nextly, a protection layer is formed on the outer surface of the bonding layer by hot fluidization forming and finally, the strippable protection layers are torn off to remove rubber outside the lateral surface of the glass panel, and thus, the front and reverse sides of the glass panel do not need to be washed, only the strippable protection layers need to be torn off and the manufacturing process of a product is greatly simplified. Meanwhile, due to coverage of the strippable protection layers on the front and reverse sides of the glass panel, a user does not need to worry about glue overflows to the front and reverse sides of the glass panel, and thus, an injection port of a forming die can be formed randomly and difficulty in injection forming is reduced. Moreover, by utilizing the characteristic of strong bonding effect of the bonding agent, the bonding agent can be well attached to the lateral surface of the glass panel and can be firmly combined with rubber, so that the falling phenomenon of the protection layer on the outer surface of the bonding layer is effectively avoided and product quality is ensured.

Description

The manufacture method of waterproof antidetonation handset touch panel

Technical field

The present invention relates to Cellphone Accessories technical field, refers in particular to a kind of manufacture method of the touch screen of mobile phone.

Background technology

With gradually popularization of the capacitance plate in mobile phone, flat sheet industries, a shortcoming of capacitance plate starts to display: Sealing is relatively poor, frangible.Capacitance plate major ingredient is glass, while having the advantages that good looking appearance, corrosion-resistant, oil rub resistance Also frangible shortcoming is possessed, and due to due to this body structure(G+G, double glazing), cause easily to occur during final assembly Gap, affects overall dust-proof effect.For this purpose, at present the method for making handset touch panel is directly on the side of face glass Injection molded elastomer and form a protective layer, using protective layer can play good water, shock etc. effect, however, this kind of method system Easily occurs following defect during work:

First, occur that glue is spilled over to the positive and negative of face glass unavoidably in injection moulding process, it is right to be that this subsequently needs The positive and negative of face glass is cleaned, so as to make troubles to making, and in order that the positive and negative of face glass is as few as possible There is glue in ground, and the injection port of mould must carry out specific setting, so as to increased injection molding difficulty;Additionally, by Not enough in the adhesion of rubber and face glass, when rubber is directly injection-moulded on face glass, protective layer is easily from glass surface Come off on plate, so as to lose protective effect.

The content of the invention

In view of this, the present invention is directed to the disappearance of prior art presence, and its main purpose is to provide a kind of waterproof antidetonation handss The manufacture method of machine touch screen, the existing handset touch panel of its energy effectively solving is using the directly injection on the side of face glass There is making trouble in rubber, difficulty is big and protective layer easily comes off from face glass.

For achieving the above object, the present invention is using such as purgation technical scheme:

A kind of manufacture method of waterproof antidetonation handset touch panel, includes following steps:

(1)Print peelable overcoat:Face glass is taken, and in the peelable overcoat of positive back face printing of face glass;

(2)Apply bonding agent:Bonding agent is coated in the side of face glass and form tack coat;

(3)Heat cure shaping:Face glass is put in mould and rubber heat cure shaping so that rubber is incorporated into The outer surface of tack coat forms protective layer;

(4)Tear peelable overcoat:Rubber beyond is torn peelable overcoat to remove face glass side is i.e. Finished product is obtained.

Used as a kind of preferred version, the peelable overcoat is light-cured type glue.

Used as a kind of preferred version, the bonding agent is made up of the raw material of following weight proportion:

Epoxy resin 56%-64%;

Polyethylene Glycol diacrylate fat 30%-39%;

Light trigger 4%-7%.

Used as a kind of preferred version, the weight proportion of the epoxy resin is 60%, the weight of the Polyethylene Glycol diacrylate fat Amount proportioning is 35%, and the weight proportion of the light trigger is 5%.

Used as a kind of preferred version, the mould includes base plate, middle plate, cover plate and pressing plate;The base plate, middle plate, Cover plate and pressing plate are folded successively set from lower to upper, and the surface of the base plate is arranged with recovery chamber, and surface of plate is arranged with die cavity, mould in this Chamber is reclaimed in chamber connection, and the surface of the cover plate is arranged with pan feeding chamber, and the bottom surface in pan feeding chamber is provided with multiple injection ports, multiple injection ports Connection die cavity, the bottom surface of cover plate is provided with for pressing on the dividing plate on face glass, and the dividing plate is located under multiple injection ports Side, the bottom surface of the pressing plate is convexly equipped with the briquetting for being embedded in pan feeding chamber, and briquetting is adapted with pan feeding chamber.

It is the base plate, middle plate, fixed each other by locating dowel between cover plate and pressing plate as a kind of preferred version Position.

Used as a kind of preferred version, the pan feeding chamber is two, and accordingly the bottom surface of the pressing plate is convexly equipped with two aforementioned briquettings.

The present invention has compared with prior art clear advantage and beneficial effect, specifically, by above-mentioned technical proposal Understand:

By in the peelable overcoat of positive back face printing of face glass, then coating knot in the side of face glass in advance Mixture forms tack coat, then, protective layer is formed by the fluidized hot outer surface for being molded over tack coat, finally by peelable protection Layer tear to remove face glass side beyond rubber, so clean without the need for the positive and negative to face glass, it is only necessary to tear Fall peelable overcoat, enormously simplify the manufacturing process of product, simultaneously because peelable overcoat to face glass it The covering of positive and negative, without having to worry about the positive and negative of excessive glue to face glass, thus the injection port of mould can be arranged arbitrarily, drop Low injection molding difficulty, additionally, having the strong characteristic of bond effect in conjunction with agent, can adhere well to face glass Side on and can there is obscission so as to effectively prevent protective layer, it is ensured that product quality with rubber strong bonded.

More clearly to illustrate the architectural feature and effect of the present invention, come to this with specific embodiment below in conjunction with the accompanying drawings It is bright to be described in detail.
