Specific embodiment
The present invention will be further described with reference to the accompanying drawings.
As shown in Figure 1, the present invention provides a kind of peripheral auxiliary frame sealing glue apparatus for coating comprising: it is built-in with sealant
Sebific duct 1, the sealant syringe needle 2 that is connected with sebific duct and the laser for detecting distance between sealant syringe needle 2 and substrate 5
Sensor further includes the gluing guide structure 3 positioned at 5 side of substrate.
In one embodiment, gluing guide structure 3 includes the gluing the initial segment 31 of beginning gluing and the painting that gluing terminates
Glue terminates section 32, is provided with gap 33 between the initial segment 31 and termination section 32.
Due to being provided with gap 33 between the initial segment 31 and termination section 32, coating is up to reaching since the initial segment 31
Terminate coating after terminating section 32, there is no gluings, the i.e. original position of auxiliary frame sealing glue at gap 33 during coating
It is produced with the interface of the clear band for having a Duan Weiwei gluing at final position, initial position and final position that gluing can be prevented
It is raw overlapping, so that excessive glue is deposited in interface and is caused box thickness ununiformity；Glue and termination when carrying out to box, at the initial segment 31
Glue at section 32 is pressed, therefore can fill up the clear band at gap 33 towards slight movement is generated at gap 33,
Make the initial segment 31 and terminate at section 32 that just intersection does not generate overlapping again, is consistent box thickness.
In one embodiment, the initial segment 31 is configured to U-shaped structure, terminates section 32 and is configured to inverted U-shaped；33, gap
Between the bottom end of the initial segment 31 and the top of termination section 32.Specific the initial segment 31 has a long side and a short side, long side base
The edge of plate 5 is connected, and the part between long side and short side is to terminate section 32 and the initial segment 31 mirror-image structure each other at gluing.
The initial segment 31 and termination section 32 are used to limit the beginning and end of gluing, are overlapped the beginning and end of gluing not,
But there are certain gaps.
In the present embodiment, the size in gap 33 is 150-250um.Preferably, the size in gap 33 is 200um, that is, is risen
The distance between bottom end of beginning section 31 and the top for terminating section 32 are 200um, make auxiliary frame sealing glue pressed and to gap
When mobile at 33, gap 33 can be filled up just.
The turning of the initial segment 31 and the corner for terminating section 32 are provided with rounded corner, and the radius of rounded corner is 0.5-1mm.
Preferably, the radius of rounded corner is 0.5mm, since when applying glue, sealant syringe needle 2 can not generate right angle in corner,
Therefore it needs to limit the initial segment 31 of gluing and terminate section 32 and is respectively provided with rounded corner.
In addition, the height of the initial segment 31 and termination section 32 is respectively less than the height of estimated peripheral auxiliary frame sealing glue to be formed 4
(i.e. box is thick), makes when carrying out to box, and the initial segment 31 and the glue terminated in section 32 can cross the initial segment 31 and terminate section 32 simultaneously
It is moved in gap 33.
The present invention also provides a kind of peripheral auxiliary frame sealing glue coating methods comprising uses above-mentioned peripheral auxiliary frame sealing
Gum coating apparatus.
Specifically, comprising the following steps:
Step 1: setting glue bearing areas and the gluing route of sealant on substrate 5.
Wherein, peripheral auxiliary frame sealing glue 4 is the sealant in liquid crystal display panel.
Further, substrate 5 is color membrane substrates or array substrate, and the application routes of peripheral auxiliary frame sealing glue 4 are set to this
Outside the display area of color membrane substrates or array substrate.As shown in Fig. 2, being coated along the outer rim of substrate 5, in figure shown in 4
Dash area be periphery auxiliary sealing frame, the clear band of gluing is existed between the beginning and end of gluing, i.e. auxiliary envelope
Frame glue 4 is unclosed, therefore the redundancy section of glass substrate can be made consistent with outside atmospheric pressure, reaches whole glass with this
The box of glass substrate is thick uniformly.
In addition, when carrying out to box, the clear band of non-gluing is provides appearance since mobile glue being occurred by pressure force
The space received, so that the box thickness for going out beginning and end is consistent.
Further, peripheral auxiliary frame sealing glue 4 is rectangle.
In the present embodiment, the width of the initial segment 31 and the width of termination section 32 are equal to the width of gluing route, gluing
The width of route is the width of the estimated peripheral auxiliary frame sealing glue 4 formed.
A kind of peripheral auxiliary frame sealing glue coating method provided by the invention, is by the initial position of coating and stop bit
The place of setting reserves size suitable space, which is not coated, but initial position and termination are accommodated when being pressed
Glue amount at position can make to intersect just at original position and final position but will not generate overlapping, therefore can make
Box thickness is consistent, and then ensure that the quality of liquid crystal display panel.
Although by reference to preferred embodiment, invention has been described, the case where not departing from the scope of the present invention
Under, various improvement can be carried out to it and can replace component therein with equivalent.Especially, as long as there is no structures to rush
Prominent, items technical characteristic mentioned in the various embodiments can be combined in any way.The invention is not limited to texts
Disclosed in specific embodiment, but include all technical solutions falling within the scope of the claims.
