Abstract
The utility model discloses a mobile phone glass back cover reversing device. The mobile phone glass back cover reversing device comprises a glass back cover. Reversing elements are arranged on the glass back cover. An ink layer and a glue layer are further arranged between the glass back cover and the reversing elements, wherein the ink layer is coated onto the glass back cover, and the glue layer is coated onto the ink layer. The reversing elements are uniformly arranged on the glass back cover. The reversing elements are made from a plastic material. The glue layer is made from hot melt adhesive. The glass back cover is made from toughened glass. Compared with the prior art, the mobile phone glass back cover reversing device of the utility model has advantage of simple process, the whole process of the glass and the plastic reversing elements is simplified, advantages of simple process and low cost are realized; the advantage of good bonding strength is realized, a large contact area exists between the glass portion and the plastic portion on one hand, and the glue is melted again in the intra-module injection moulding process on the other hand, so the advantage of good bonding strength is realized between the glass and the plastic reversing elements; the glass is easy to fabricate: no structure, such as a hole, a groove, etc., exists on the glass, the glass is easy to process and fabricate, so the cost is reduced.
Description
Technical field
The utility model relates to a kind of portable terminal handheld device, particularly relates to a kind of mobile phone glass back cover back-off device.
Background technology
Along with the development of smart mobile phone, use glass material also more and more as the occasion of mobile phone component.But glass belongs to a kind of fragile material, is difficult to the assembly structures such as processing back-off thereon.Therefore, the glass part that uses on the mobile phone now generally all is that the glue bonding is assembled, or is assembled together by in-mould injection technique, but the glass structure of this technique can't carry out dismounting, has limited the application of glass material on mobile phone.
The utility model content
The purpose of this utility model is to overcome the deficiencies in the prior art, and a kind of mobile phone glass back cover back-off device is provided, and has solved the problem of glass back cover back-off poor toughness, and is simple in structure, simplifies technique, reduces cost of manufacture.
In order to achieve the above object, the technical solution adopted in the utility model is: a kind of mobile phone glass back cover back-off device, comprise the glass back cover, be provided with back-off spare on the described glass back cover, between glass back cover and back-off spare, also be provided with ink lay and glue layer, ink lay is coated on the glass back cover, and glue layer is coated on the ink lay.
Further, described back-off spare evenly is arranged on the glass back cover.
Further, described back-off spare is the plastics back-off.
Further, described glue layer is made of PUR.
Further, described glass back cover is toughened glass.
Compared with prior art, the beneficial effects of the utility model are: technique is simple, and the whole technological process of glass and plastic cement back-off is less, and technique is simple, and cost is lower; Adhesion strength is good, and glass and plastic cement partly have very large contact area on the one hand, owing to glue when the in-mould injection moulding melts again, therefore, between glass and the plastic cement back-off very high adhesion strength is arranged on the other hand; Glass is made simple: on glass without structures such as hole slots, glass processing is made simple, has reduced cost.
Description of drawings
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the enlarged drawing of local A among Fig. 1.
Embodiment
Be elaborated with reference to accompanying drawing below in conjunction with embodiment, in order to technical characterictic of the present utility model and advantage are carried out more deep annotation.
Structural representation of the present utility model is shown in Fig. 1 .2, a kind of mobile phone glass back cover back-off device, comprise glass back cover 1, be provided with back-off spare 4 on the described glass back cover 1, between glass back cover 1 and back-off spare 4, also be provided with ink lay 2 and glue layer 3, ink lay 2 is coated on the glass back cover 1, and glue layer 3 is coated on the ink lay 2.
Further, described back-off spare 4 evenly is arranged on the glass back cover 1.
Further, described back-off spare 4 is the plastics back-off.
Further, described glue layer 3 is made of PUR.
Further, described glass back cover 1 is toughened glass.
Operation principle of the present utility model is: plastic cement back-off and whole glue layer 3 parts connect as one, and make the plastic cement back-off have enough strength and toughnesses; Glass back cover 1 keeps intrinsic light transmission and the hardness of glass, the surface is without hole slot structure influence outward appearance, glass table silk-screen one deck printing ink (covering decoration function), silk-screen one deck hot melt glue on ink lay 2, put into in-mould injection forming plastic cement back-off part, glass back cover and plastic cement back-off are bonded together firmly.
Technical process of the present utility model is: make first glass back cover 1, then at glass surface difference ink for screen printing layer 2 and glue layer 3(PUR) and carry out respective handling, at last glass back cover 1 is put into mould, injection mo(u)lding plastic cement back-off part.
Technological requirement of the present utility model is: the glass back cover adopts toughened glass, and thickness is 0.50-1.2mm not; Glue layer requires to adopt hot melt glue, can again melt under the temperature of melt plastic cement, firmly is bonded together with the plastic cement part; During in-mould injection, the reply glass surface is cleared up, and prevents that residual impurity from making glass and the bad glass fragmentation faced that causes of die face applying.
Above content is in conjunction with concrete preferred implementation further detailed description of the utility model, can not assert that implementation of the present utility model is confined to these explanations.For the utility model one of ordinary skill in the art, without departing from the concept of the premise utility, make simple change or optimization, all should be considered as protection range of the present utility model.
