Description

Display frames production method

Technical field

The present invention relates to LCD frame field, particularly relate to display frames production method.

Background technology

In existing display frames production method, front frame extrudes burr and type matrix after cutting outside punching, then punching press convex closure by four Edge Bends, then excise form hole waste material on substrate, and before final, frame is shaping.Punching after backboard needs in producing again to draw materials from material volume, rushes bending and molding after convex closure and reinforcement.Because front frame is frame structure, front frame is drawn materials in process has a large amount of former materials cut, adds a large amount of costs.In backboard production run, because crimp is drawn materials together with back plane substrate, require high to punch press.Be unfavorable for frame backboard before production large scale.

Summary of the invention

The object of this invention is to provide one and can reduce leftover pieces, reduce the display frames production method of production cost.

According to an aspect of the present invention, a kind of display frames production method is provided.Comprise the following steps: stamp out front frame substrate from material volume; By front frame substrate bending; Before after bending, frame substrate stamps out form hole, obtain waste material substrate and front frame; Stamp out folding edges of back from material volume, make this folding edges of back bending; Waste material substrate is fixedly connected with the folding edges of back after bending, forms backboard.Middle waste material substrate in front frame production run, for the production of back plane substrate, greatly reduces materials cost, has saved starting material.

In some embodiments, front frame substrate is square, and edge, front frame substrate four limit forms the first pressing part.

In some embodiments, also comprise, former frame substrate corner forms pilot hole.Pluralize the punching of whole piece metal material a front frame substrate work piece, is sheathed on the register pin of weld jig, makes front frame substrate orientation on weld jig by the pilot hole on front frame substrate, adds and not easily occur man-hour to loosen and skew, make welding tightr.

In some embodiments, former frame substrate forms convex closure.After LCD frame is shaping, substrate surface needs fixed television circuit component, because circuit component and substrate are all metal material, directly contact for preventing circuit original paper and substrate and cause short circuit, substrate surface forms convex closure, convex closure, by circuit component jack-up, makes circuit component directly not contact with substrate surface.

In some embodiments, front frame substrate forms reinforcement.In large-sized LCD frame, because substrate thickness is inadequate, easily there is the phenomenons such as bending, according to substrate thickness needs, many reinforcements are set at substrate surface, to meet thickness needs.

In some embodiments, front frame is frame structure.

In some embodiments, the folding edges of back after waste material substrate and bending is by weld or riveting method is fixedly connected with.According to the different size of front frame and backboard, can select to weld or the mode of riveted joint connects waste material substrate and folding edges of back.

Embodiment

Below in conjunction with drawings and the specific embodiments the present invention is described in further detail explanation.

Fig. 1 show schematically show display frames production method according to an embodiment of the present invention.As shown in Figure 1, display frames production method of the present invention comprises the following steps:

Front frame substrate is stamped out from material volume;

By the bending of front frame substrate;

Punching press form hole on frame substrate before after bending, obtains waste material substrate and front frame;

From material volume punching press folding edges of back, after this folding edges of back is bent;

Waste material substrate is fixedly connected with the folding edges of back after bending, forms backboard.

As shown in Figures 2 to 4, use stamping machine to stamp out front frame substrate 101 from material volume, front frame substrate 101 is square.Front frame substrate 101 4 limit excision " 7 " font waste material 107.Edge, front frame substrate 101 4 limit is provided with the first pressing part 109.For the pilot hole 111 fixing with station when front frame substrate 101 4 jiaos is provided with punching press.Whole piece metal material is stamped out one piece complete before after frame substrate work piece, pilot hole 111 on front frame substrate 101 is sheathed on the register pin of weld jig, make front frame substrate 101 be positioned on weld jig, add and not easily occur man-hour to loosen and skew, make welding tightr.After stamping out front frame substrate 101, to front frame substrate 101 punching and edge-cutting, trimming is smooth.

As shown in Figure 5, Figure 6, before the bending of front frame substrate 101, punch ram convex closure 205 and reinforcement 207 are used to front frame substrate 101 surface.The waste material substrate that front frame substrate excises out is as the substrate of backboard, back plate surface needs fixed television circuit component, because circuit component and substrate are all metal material, directly contact for preventing circuit original paper and substrate and cause short circuit, substrate surface forms convex closure, convex closure directly contacts with the insulating material at circuit component edge, by circuit component jack-up, circuit component is not directly contacted with substrate surface.Reinforcement 207 is that elongated metal is protruding, and reinforcement 207 and front frame substrate 101 1 ribs are arranged at front frame substrate 101 on the surface abreast.In large-sized LCD frame, because substrate thickness is inadequate, easily there is the phenomenons such as bending, according to substrate thickness needs, many reinforcements are set at substrate surface, to meet thickness needs.After convex closure 205 and reinforcement 207 punching press complete, by the opposite side surface bending of front frame substrate 101 4 limit to convex closure 205 protrusion direction.Brake techniques is prior art, and use punch press to carry out bending to front frame substrate 101, after bending, four Edge Bend part place planes and substrate place interplanar angle are 90 degree.

As shown in Figure 7, Figure 8, after before using stamping machine after bending, frame substrate 101 center stamps out form hole 103, front frame substrate 101 hollow after bending, form framework pattern, front frame 100 is shaping.Waste material substrate 105 is square, and waste material substrate 105 surface has been provided with the convex closure 205 and reinforcement 207 above mentioned.
