Abstract

The utility model relates to a different-material same-body shaped backlight module group rubber frame, which comprises a frame body which is made of hard plastic and is provided with a combining portion, and a pad strip which is combined on the combining portion of the frame body, wherein the pad strip is made of flexible plastic which is more flexible than the frame body. The utility model is led to shape with flexible pad strips on the same body on the hard frame body by means of twice different-material ejecting shapes, thereby reaching the behaviors of simple manufacture and stable combination.

Description

Different material is with body formed module glue frame backlight

[technical field]

The utility model relates to a kind of module glue frame backlight, particularly relate to a kind of be installed in the module backlight and the different material of consubstantiality ejection formation with body formed module glue frame backlight.

[background technology]

Shell block in the module backlight of LCD (LCD), except having a base plate for the installation of lamp source, also has the frame that is installed in base plate four sides, this four side arch can be used for optical elements such as LGP, diffuser plate, prismatic lens and liquid crystal panel are installed, to project required optical effect.And be given a shock or damage for fear of optical element, the soft filler strip of a slice can be installed again at each frame top usually by manufacturer, puts for the optical element pad.

In addition; shell block was for weight reduction in the past; generally can utilize plastic material to make; yet increase day by day along with the LCD size; for intensity and the stability of keeping lamp source and module backlight; manufacturer usually can be with a part of member of this shell block for example base plate or two long side frames; utilize metal material to make; and remainder member for example four side frame or two short side frames; still can utilize plastic material to make, below the frame (to call the glue frame in the following text) only made with plastic material wherein illustrate.

As Fig. 1 and shown in Figure 2, a kind of module glue frame 1 backlight in the past, comprise: filler strip 12 on the joint portion 111 is made and be stacked in to a framework 11, of making and have a joint portion 111 by rigid plastics by flexible plastic, and one is used for filler strip 12 is sticked on adhesive 13 on the joint portion 111.This adhesive 13 is a two-sided adhesive tape.One base plate (figure does not show) and several glue frame 1 windings are become a shell block, the lamp source is installed in this shell block, again several pieces optical elements are placed on filler strip 12 tops of these glue frames 1, just can be mounted to a module backlight.

Though above-mentioned glue frame 1 can stick on filler strip 12 on the joint portion 111 by adhesive 13, yet when pasting, must adjust contraposition and applying carefully, it is consuming time comparatively to take a lot of work when being sticked, and the flaw situation of crooked injustice accidentally will take place, reduce production capacity and product yield easily, bonding process is quite taken a lot of work consuming time, also can improve processing cost relatively.Moreover this adhesive 13 lowers because of material and environment cause associativity easily, comes off so therefore filler strip 12 may be peeled off, and still remains in the design to be improved.

[utility model content]

The purpose of this utility model is to be to provide a kind of to have the different material of easy to manufacture and the firm effect of combination with body formed module glue frame backlight.

The different material of the utility model comprises with body formed module glue frame backlight: one makes and has the framework of a joint portion by rigid plastics, and a filler strip that is combined on the joint portion of framework.This filler strip is to be made by the flexible plastic that is softer than framework relatively.

The beneficial effects of the utility model are: by twice different material ejection formation, can form soft filler strip by consubstantiality on the framework of hard, so can reach easy to manufacture and in conjunction with firm effect.

[specific embodiment]

Below in conjunction with drawings and Examples the utility model is elaborated:

As shown in Figure 3 and Figure 4, the different material of the utility model comprises with the preferred embodiment of body formed module glue frame backlight: a framework 2, and a filler strip 3.

This framework 2 is to be made by the thermosetting plastic material of hard, for example: Merlon (Polycarbonate), Merlon+glass fibre (Polycarbonate+Glass Fiber), acrylonitrile-butadiene-phenylethylene co-polymer (Acrylonitrile-Butadene-Styrene), polycarbonate/acrylonitrile eyeball-butadiene-styrene plastic materials such as (Polycarbonate/ABS Alloy), and have a faying face 21 that is positioned at the top, an and joint portion 22 that is recessed to form downwards by this faying face 21.This joint portion 22 is one elongated slot.

This filler strip 3 is to be made by the soft thermoplastic plastic's material that is softer than framework 2 relatively, for example: thermoplastic elastomer (TPE) (Thermoplastic elastomer), thermoplastic sulfurized rubber plastic materials such as (Thermoplasticvulcanizate), be that consubstantiality is combined on the joint portion 22 of framework 2, and have an end face 31 away from joint portion 22.These end face 31 positions are higher than the faying face 21 of framework 2.Certainly this filler strip 3 also can be separated into the section portion of several sections each intervals, and framework 2 also can make joint portion 22 directly no longer describe in detail at this on faying face 21 and toward lower recess, just make filler strip 3 be formed directly on the faying face 21 position.

When making this glue frame, can make by a double-material jet formation machine (figure does not show), this double-material jet formation machine is to increase a material pipe and Improvement type nozzle on the traditional type Jet forming machine, and in two material pipes, be installed in the plastic material that material is different and compatibility is high respectively, then in mould, successively shoot material again and mold framework 2 and filler strip 3, form filler strip 3 with consubstantiality on framework 2.Certainly on making, also can make this glue frame by two traditional type Jet forming machines (figure does not show), just in the material pipe of these Jet forming machines, be installed in the different plastic material of soft or hard respectively, ejection formation in a mould successively more so equally can consubstantiality ejection formation glue frame of the present utility model.

During installation, several glue frames are arranged in pairs or groups a base plate (figure does not show) in conjunction with constituting a shell block, several lamp sources (figure does not show) are installed at contiguous base plate place, and on the end face 31 of filler strip 3, place an optical unit 4 reposefully, this optical unit 4 can have optical elements such as LGP, diffuser plate, prismatic lens and liquid crystal panel, then encapsulates to finish assembling again.

As shown in the above description, the different material of the utility model with body formed module glue frame backlight in design, be by twice different material ejection formation of soft or hard, make the utility model consubstantiality on the framework 2 of hard form soft filler strip 3, and the 3 energy molten adhere of the filler strip after the moulding are on framework 2, the unexpected flaw situation that comes off and crooked injustice also can not occur, so it not only can shorten processing procedure and process time, quality of finished yield and production capacity also can significantly promote, and can cut down finished cost, therefore the utlity model has easy to manufacture and, can reach the purpose of this utility model really in conjunction with firm effect.
