Description

Jig for manufacturing backlight module

Technical field

The present invention relates to a kind of module backlight, particularly relate to a kind of jig for manufacturing backlight module.

Background technology

Module backlight is one of key part and component of panel of LCD, because liquid crystal itself is not luminous, the function of module backlight is well-off brightness and the light source that is evenly distributed, and makes its normally show image.The LED-backlit module mainly comprises parts such as housing, reflector plate, light guide plate, diffusion sheet, and these parts need be superimposed together.The assembling mode of the LED-backlit module of commonly using is to adopt manual mode that each parts is superimposed together, and has defectives such as assembly precision is poor, production efficiency is low, can't satisfy present high precision display screen assembling needs, and problems such as light leak can appear in display screen.

Summary of the invention

The object of the present invention is to provide a kind of assembly precision height, jig for manufacturing backlight module that production efficiency is high.

For achieving the above object, technical solution of the present invention is:

The present invention is a kind of jig for manufacturing backlight module, and it mainly is made up of cope match-plate pattern, upper die and lower die, lower bolster and air extractor; One end of described cope match-plate pattern is hinged on an end of lower bolster, and cope match-plate pattern can cover on the lower bolster around its hinged end swing, and mould is installed on flat cope match-plate pattern; The described patrix of workpiece that is used for fixing is by the pipeline connection air extractor; The counterdie of installing frame shape on flat lower bolster, the inside casing size and the patrix peripheral size of this counterdie match, the inside casing of described counterdie can allow patrix just in time be pressed into, in counterdie circle mouth periphery offer with module backlight in the locating slot that matches of glue frame size.

The present invention also comprises backing plate, and backing plate and patrix are installed on cope match-plate pattern in regular turn, and is stepped after backing plate, patrix, cope match-plate pattern are superimposed, is reserved with a plurality of guide pillar holes that allow guide pillar penetrate on backing plate.

Offer counterbore and cross-drilled hole on patrix, this counterbore communicates with cross-drilled hole, and the openend of counterbore leads to patrix absorption workpiece face, and an end of cross-drilled hole leads to sidewall and pipeline connection.

The present invention also comprises two height reference columns; Described two height reference columns are fixed on the lower bolster and lay respectively at the both sides of counterdie housing, the distance between two height reference columns greater than with the width that is installed in the backing plate on the patrix, be used to limit the distance of patrix closing counterdie.

The present invention also comprises guide pillar; This guide pillar one end is fixed on the backing plate, and its other end can be inserted in downwards in the pilot hole on the counterdie, to guarantee cooperating of patrix and counterdie.

After adopting such scheme, the present invention is adsorbed on shading rubber belt on the patrix, with last prismatic lens, prismatic lens, diffusion sheet, light guide plate, glue frame etc. are installed in the locating slot of counterdie down, by on be molded into counterdie, just can finish the superimposed of module backlight.Because each parts in the module backlight are composition modules backlight that the mode by mold pressing is superimposed together, so the present invention has assembly precision height, production efficiency advantages of higher.

The present invention is further illustrated below in conjunction with the drawings and specific embodiments.

Embodiment

As shown in Figure 1 and Figure 2, the present invention is a kind of jig for manufacturing backlight module, and it mainly is made up of cope match-plate pattern 1, backing plate 2, patrix 3, counterdie 4, lower bolster 5, air extractor 6, upset handle 7, height reference column 8, guide pillar 91, material reference column 92.

One end of described cope match-plate pattern 1 is hinged on an end of lower bolster 5 by rotating shaft, cope match-plate pattern 1 can cover on the lower bolster 5 around its hinged end swing, backing plate 2 and patrix 3 are installed on flat cope match-plate pattern 1 in regular turn, it is rectangular stepped after backing plate 2, patrix 3, cope match-plate pattern 1 are superimposed, on backing plate 2, be reserved with a plurality of guide pillar holes that allow guide pillar 91 penetrate, so that adapt to the needs of different size module 10 backlight (as shown in Figure 5).At the other end of cope match-plate pattern 1 a upset handle 7 is installed.Described patrix 3 sidewalls that are used for fixing workpiece are communicated with air extractor 6 by pipeline 61, on patrix 3, offer counterbore 31 and cross-drilled hole 32, this counterbore 31 communicates with cross-drilled hole 32, and the openend of counterbore 31 leads to patrix 3 absorption workpiece faces, and an end of cross-drilled hole 32 leads to sidewall and is communicated with pipeline 61.Periphery at patrix 3 is equipped with two root timber material reference columns 92 (as shown in Figure 2), and this material reference column 92 is used for the installation site that module 10 backlight limits shading rubber belt 101.

The counterdie 4 of installing frame shape on flat lower bolster 5, the inside casing size of this counterdie 4 and patrix 3 peripheral size match, the inside casing of described counterdie 4 can allow patrix 3 just in time be pressed into, in counterdie 4 circle mouth periphery offer with module 10 backlight in the locating slot 41 (as shown in Figure 3) that matches of glue frame 106 (as shown in Figure 6) size, glue frame 106 can just in time fall in this locating slot 41.

Described two height reference columns 8 are fixed on the lower bolster 1 and lay respectively at the both sides of counterdie 4 housings, the distance of two height between the reference column 8 greater than with the width that is installed in the backing plate 2 on the patrix 3, be used to limit the distance (as shown in Figure 4) of patrix 3 closing counterdies 4.

Described patrix 3 and counterdie 4 are to change according to the size of module 10 backlight (as shown in Figure 5).

Described guide pillar 91 1 ends are fixed on the backing plate 2, and guide pillar 91 other ends can be inserted in downwards in the pilot hole 42 on the counterdie 4, to guarantee that patrix 3 cooperates with the accurate of counterdie 4.

The present invention is aspect material selection: cope match-plate pattern 1 and lower bolster 5 are selected the bakelite material for use, and patrix 3 and counterdie 4 are selected aluminium for use.

Principle of work of the present invention (shown in Figure 5) as Fig. 1 reference:

1, module 10 backlight is limited shading rubber belt 101 and be placed on the patrix 3, push air extractor 6 switches, shading rubber belt 101 is adsorbed on the patrix 3;

2, will go up prismatic lens 102, following prismatic lens 103, diffusion sheet 104, light guide plate 105, glue frame 106 etc. installs in the locating slot 41 of counterdies 4;

3, hold upset handle 7, patrix 3 is pressed into counterdie 4, promptly finish the superimposed assembling of module 10 backlight.

The above, only be preferred embodiment of the present invention, the concrete form of upper die and lower die can be selected for use as required, so can not limit scope of the invention process with this, the i.e. equivalence of doing according to the present patent application claim and description changes and modifies, and all should still belong in the scope that patent of the present invention contains.
