Description

The aluminium extruded type outside framework of LCD

Technical field

The utility model relates to a kind of aluminium extruded type outside framework of LCD.

Background technology

The available liquid crystal display; its outside framework all is by the manufacturing of resin direct injection; though have cheaper manufacturing cost; but resin be can't Regeneration Treatment material; do not reclaim requirement so met current environmental protection; so that deriving many environmental issues, is that at present this industry faces the problem of the most urgent solution.

The LCD outside framework made from above-mentioned resin, it is in order to reach the requirement that meets EMI (radiation proof), usually in framework, install metal partion (metp), to reach the purpose that reduces radiation, right this metal partion (metp) is generally a kind of iron sheet material, add the weight of resin housing, so its overall weight is just quite heavy.

Summary of the invention

The purpose of this utility model provides a kind of aluminium extruded type outside framework of LCD, and this framework is with the base material of aluminium as the LCD outside framework, to realize the lightweight and the recycling of product.

Make the LCD outside framework with the aluminum current base material; generally can adopt and forge method for making or aluminium extruded type method for making; yet consider the manufacturing cost factor; because of the die cost of forging method for making higher; and die life is also short; so be not suitable for; so only adopting with the lower aluminium extruded type method for making of die cost, present stage conforms with the production economic benefit; therefore the utility model proposes a kind of aluminium extruded type outside framework of LCD; not only in manufacturing cost than the tool economic benefit; and aluminium, framework directly can reduce radiation, can meet environmental protection again and reclaim requirement.

Above-mentioned purpose of the present utility model is to realize like this, a kind of aluminium extruded type outside framework of LCD, mainly make the framework kenel that the solid welding framework is docked respectively in front frame strip institute behind front frame strip before four groups and four groups by array with the strip aluminium moulding processing of aluminium extrusion molding, wherein: this preceding front frame strip integrally formedly on the medial surface goes out a cross rib in docking; And should before front frame strip and the back front frame strip cut into a butt joint corner respectively at both ends of the surface, front frame strip and back front frame strip can utilize upright front frame body and the rear frame body that forms rectangle of this butt joint corner linking group in twos before being provided with these four groups, and with of the joint enforcement welding of arc welding mode with front frame body and rear frame body, cause front frame body and the afterframe physical efficiency made by aluminium extruded type firmly to connect to cuboid, with front frame body and the grinding of rear frame body front surface and baking vanish and make face of weld and reach a jointless burnishing surface attractive in appearance, so the front frame body of aluminium extruded type or rear frame body are promptly formed the LCD of aluminium extruded type outside framework in interface framework location liquid crystal panel.

Below cooperate with regard to the utility model specific embodiment and graphicly to be described as follows in detail:

Embodiment

The aluminium extruded type outside framework of the utility model LCD be by array with the processing of the strip aluminium moulding of aluminium extrusion molding make front frame strip behind front frame strip before four groups and four groups dock the framework kenel of solid welding framework respectively.

Consult shown in Figure 1, for the aluminium extruded type outside framework of the utility model LCD is made process flow diagram, in step 1, with aluminium in extrusion shaper be shaped the aluminium moulding 6 of array strip, the kenel (as shown in Figure 4) of the kenel (as shown in Figure 2) of front frame strip 61 or back front frame strip 62 before this aluminium moulding 6 can be, and preceding front frame strip 61 goes out cross rib 611 in butt joint is also integrally formed on the medial surface.

In step 2, preceding front frame strip 61 and back front frame strip 62 are placed on the cutting machine, be provided with preceding front frame strip 61 and front frame strip 62 two ends, back are cut into required butt joint corner (as Fig. 3 and shown in Figure 5).

In step 3, front frame strip 62 places on the stamping machine after getting before one group front frame strip 61 and one group, but go out feed flow crystal panel operating key and the ccontaining key zone 612 (as shown in Figure 6) of the protruding dew of pilot lamp for front frame strip 61 before making, and make back front frame strip 62 inner edge sides form a concane gap 621 (as shown in Figure 8).

In step 4, the butt joint corner place of preceding front frame strip 61 and back front frame strip 62 is adopted in a kind of arc welding mode, so allow the aluminium thin material mutual solid welding link, and when welding, do not have the phenomenon that burnt hole takes place yet, so four groups preceding front frame strip 61 or back front frame strip 62 just can be distinguished upright front frame body 7 (as shown in Figure 7) or the rear frame body 8 (as shown in Figure 8) that forms rectangle of mutually firm binding group, and should also implement welding (as shown in Figure 9) in the lump by preceding front frame strip 61 each cross rib 611 joint, strengthened the integrated support intensity of front frame body 7, and this rear frame body 8 also can be locked the upright dividing plate 90 of pair group in addition, be provided with the liquid crystal panel of group frame is strengthened retaining group and supporting role, and lock pays a bottom surface aluminium sheet 91, and the bottom frame groove that is provided with sealing rear frame body 8 forms one and finishes plane (as shown in figure 11).In step 5, front frame body 7 or the rear frame body 8 superficies welds organized after standing are adopted with abrasion wheel grinding, make its face of weld reach a burnishing surface 3 and help carrying out surperficial paint baking, make its surface form a smooth beautiful outward appearance, promptly finish the front frame body or the rear frame body goods of aluminium extruded type.

Learn by above-mentioned explanation, this front frame body 7 and rear frame body 8 utilize rear frame body 8 solid welding aluminium posts with locking fixation liquid crystal panel, again front frame body 7 corresponding lids are placed locking cover cap location on the rear frame body 8, can finish the aluminium extruded type outside framework (as shown in figure 10) of LCD, so LCD of outside framework institute framework, have appearance attractive in appearance and light-weighted demand equally, and because of with the aluminium framework as LCD outside framework base material, can directly reduce radiation, the outside framework made from resin compared to conventional liquid crystal, can save the material cost that it installs iron plate additional, Zheng Ti weight is also alleviated relatively, and the recyclable again Regeneration Treatment of aluminium condition frame meets environmental protection requirement very much.
