Description

The LCD MODULE burnishing device

Technical field

The present invention relates to a kind of device, particularly relate to a kind of burnishing device that is used for fixing LCD MODULE.

Background technology

Fig. 1 is the synoptic diagram of available liquid crystal display module, see also Fig. 1, traditional LCD MODULE 10 is superimposed on display panels 11 with a colored filter 12 (color filter), superimposed again backlight module (not shown) and to install external stability framework (not shown) additional made.It is made that display panels 11 presss from both sides a liquid crystal layer with two electro-conductive glass, and therefore, traditional display panels 11 can avoid the liquid crystal molecule of display panels 11 inside to flow out with the liquid crystal injecting port sealing of UV glue 13 with display panels 11.

Display panels 11 and colored filter 12 are glass material, in the manufacturing process of LCD MODULE 10, when liquid crystal is often irritated because of human factor, mechanical handing or display panels 11 in the surface of display panels 11 and colored filter 12, form scratch at panel surface, and these scratches can influence the display quality of LCD greatly.It all is to be used as the defective products recycling mostly that there is the panel of scratch on general surface, but for asking the saving cost, some manufacturer can carry out the heavy industry polishing to the not dark panel of surperficial scratch.Because the material brittle of panel is split, and can't use the general mode that grips, therefore can increase the degree of difficulty of heavy industry polishing.

Summary of the invention

Embodiment

Fig. 2 A is the top view of LCD MODULE burnishing device of the present invention, and Fig. 2 B is the cut-open view in a-a cross section among Fig. 2 A.Please refer to Fig. 1, Fig. 2 A and Fig. 2 B, LCD MODULE burnishing device of the present invention (tool) comprises plummer 20, first depression, 21 and second depression 22.Plummer 20 is an organic glass (bright olefin(e) acid) desktop or general Plastic table top, because the hardness of organic glass and plastics is all low than display panels 11 and colored filter 12, therefore when display panels 11 or the surface of colored filter 12 contact first depression 21 or second cave in 22 surperficial the time, can not damage the mistake panel again, reproduce into scratch at panel surface.

First depression 21 is one first depth d for the degree of depth on the plummer 20 ₁Depressed part, and first depression 21 shape and display panels 11 be all rectangle (but also can be other shape), and first cave in 21 the length L ₁, width W ₁Also length and the width with display panels 11 is identical, therefore, puts into first depression down 21 the time when LCD MODULE 10 with display panels 11, and LCD MODULE 10 can be fixed by first depression 21, and can't move horizontally arbitrarily.

Second depression 22 is one second depth d for the degree of depth on the plummer 20 ₂Depressed part, and second depression 22 shape and colored filter 12 be all rectangle (but also can be other shape), and second cave in 22 the length L ₂, width W ₂Also length and the width with colored filter 12 is identical, therefore, puts into second depression down 22 the time when LCD MODULE 10 with colored filter 12, and whole LCD MODULE 10 can be fixed by second depression 22, also can't move horizontally arbitrarily.

Please refer to Fig. 2 A and Fig. 2 B, LCD MODULE burnishing device 20 of the present invention all has one at first depression, 21 and second depression, 22 places and is cruciform groove 212,222, this groove 212,222 to the first depressions, 21 and second depression 22 is dark, can lower when LCD MODULE and put into first depression, 21 or second depression vacuum suction effect that produces 22 time, the application of force is improper when preventing LCD MODULE because of taking-up breaks.In addition, these grooves also can be many grooves that are parallel to each other, or the surface of cutting arbitrarily, as long as do not damaging under the display panels 11 or the situation on colored filter 12 surfaces, the vacuum suction of reduction effect can be arranged also.

Because the liquid crystal injecting port of general display panels can seal with UV glue, and can form a projection (as shown in Figure 1) at liquid crystal injecting port after the UV adhesive curing, interfere with display panels for fear of first groove 21, second groove 22, and make display panels 11 can't insert first depression 21 or colored filter 12 can't be inserted in second depression 22.Therefore, in this embodiment, edge, cruciform groove 212 in first depression, 21 and second depression 22,222 two ends up and down, respectively has a circumferential notch 211,221, these circumferential notches 211,221 position is corresponding to the liquid crystal injecting port on the LCD MODULE, its degree of depth is also dark than first depression, 21 and second depression 22, so just can avoid because of the UV of the liquid crystal injecting port place glue of display panels protrudes, and can't put in first depression, 21 and second depression 22, can't be with the fixing LCD MODULE of first depression, 21 and second depression 22.Shown in Fig. 2 A,,,, include in scope of the present invention as other easy shape of processing such as rectangle if change other shape into corresponding to the circumferential notch 211,221 of the liquid crystal injecting port of display panels.

In addition, respectively be provided with four circular depressed 213,223 in four corners of first depression, 21 and second depression 22, the staff who conveniently carries out the heavy industry polishing places or takes out LCD MODULE.

Synoptic diagram when Fig. 3 A carries out the heavy industry polishing for the first depression carrying LCD MODULE of Fig. 2 A.Please refer to Fig. 3 A, because the display panels 11 of general LCD MODULE can be bigger slightly than colored filter 12, therefore, as long as first depth d of first depression 21 ₁Can be a bit larger tham or equal the thickness of display panels 11, and display panels 11 is vertically put into first depression 21, fixing LCD MODULE just, and the heavy industry polishing is carried out on the surface of 30 pairs of colored filters 12 of available robotization polissoir.

Synoptic diagram when Fig. 3 B carries out the heavy industry polishing for the second depression carrying LCD MODULE of Fig. 2 A.Please refer to Fig. 3 B, because the zone that is not usually covered by colored filter 12 on display panels 11 can have control circuit, and also a little less than this control circuit is highly brittle, therefore, second depth d of the embodiment of the invention second depression 21 ₂Be slightly smaller than the thickness of colored filter 12, therefore, when colored filter 12 is put into second depression, display panels 11 can form a gap g with plummer 20 surfaces, at this moment, can avoid on the one hand the circuit scratch at display panels 11 back sides, fixing LCD MODULE again utilizes the surface of 30 pairs of display panels 11 of robotization polissoir to carry out the heavy industry polishing on the one hand.

Burnishing device utilization depression of the present invention is LCD MODULE fixedly, rather than utilizes general method of clamping to fix, and therefore can reduce the probability that improper clamping causes panel breakage, accelerates the speed of panel reworking polishing, and the saving product is the processing time again.

Though disclosed the present invention in conjunction with above preferred embodiment; yet it is not in order to limit the present invention; any skilled personnel can do a little change and retouching, so protection scope of the present invention should be with being as the criterion that claim was defined without departing from the spirit and scope of the present invention.
