Specific embodiment
Below in conjunction with accompanying drawing, the invention will be further described.
As shown in figure 1, the invention provides a kind of peripheral auxiliary frame sealing glue apparatus for coating, it includes：It is built-in with sealant
The sealant syringe needle 2 that is connected with sebific duct of sebific duct 1 and the laser for detecting distance between sealant syringe needle 2 and substrate 5
Sensor, also including the gluing guide structure 3 positioned at the side of substrate 5.
In one embodiment, gluing guide structure 3 includes the painting that the gluing the initial segment 31 and gluing that start gluing terminate
Glue terminates section 32, and gap 33 is provided 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, therefore it is coated with up to reaching since the initial segment 31
Terminate coating after terminating section 32, do not have the original position of gluing, i.e. auxiliary frame sealing glue at gap 33 during coating
And have at final position one section be non-gluing clear band, be prevented from gluing original position and final position interface produce
It is raw overlapping, excessive glue is deposited in interface and is caused box thickness ununiformity；When carrying out to box, glue and termination at the initial segment 31
Glue at section 32 is pressed, therefore can be towards the slight movement of generation at gap 33, you can the clear band filled up at gap 33,
Make the initial segment 31 and terminate just intersecting at section 32 and not producing overlapping, be 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 top of the bottom of the initial segment 31 and termination section 32.Specific the initial segment 31 has a side long and a short side, its side base long
The edge of plate 5 is connected, and the part between side long and short side is at gluing, to terminate section 32 and the initial segment 31 mirror-image structure each other.
The initial segment 31 is used to limit the beginning and end of gluing with section 32 is terminated, and makes the beginning and end of gluing misaligned,
But leave certain gap.
In the present embodiment, the size in gap 33 is 150-250um.Preferably, the size in gap 33 is 200um, that is, rise
The distance between the bottom of beginning section 31 and the top for terminating section 32 are 200um, make auxiliary frame sealing glue pressed and to gap
When being moved at 33, gap 33 can be filled up just.
The turning of the initial segment 31 is provided with rounding with the corner for terminating section 32, and the radius of rounding is 0.5-1mm.
Preferably, the radius of rounding is 0.5mm, because when gluing is carried out, sealant syringe needle 2 cannot produce right angle around the corner,
Therefore the initial segment 31 that will limit gluing is needed to be respectively provided with rounding with section 32 is terminated.
Additionally, the height of the initial segment 31 and termination section 32 is respectively less than the height for being expected to the peripheral auxiliary frame sealing glue 4 to be formed
(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
In moving to gap 33.
Present invention also offers a kind of peripheral auxiliary frame sealing glue coating method, it is included using above-mentioned peripheral auxiliary frame sealing
Gum coating apparatus.
Specifically, comprise the following steps：
The first step：Glue bearing areas and the gluing route of sealant are set 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 base palte, and the application routes of peripheral auxiliary frame sealing glue 4 are arranged at this
Outside the viewing area of color membrane substrates or array base palte.As shown in Fig. 2 be coated along the outer rim of substrate 5, in figure shown in 4
Dash area for periphery auxiliary sealing frame, the clear band of gluing is existed between the beginning and end of its 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, and whole glass is reached with this
The box of glass substrate is thick uniform.
Additionally, when carrying out to box, the clear band of non-gluing due to the glue being moved by pressure force to provide appearance
The space received, so that the box thickness that beginning and end goes out is consistent.
Further, peripheral auxiliary frame sealing glue 4 is rectangle.
In the present embodiment, the width of the width of the initial segment 31 and termination section 32 is equal to the width of gluing route, gluing
The width of route is the width of the estimated peripheral auxiliary frame sealing glue 4 for being formed.
A kind of peripheral auxiliary frame sealing glue coating method that the present invention is provided, is by the original position and stop bit in coating
The place of putting reserves size suitable space, and the space is not coated, but original position and termination are accommodated when being pressed
Glue amount at position, you can make at original position and final position it is just intersecting but will not produce it is overlapping, therefore, it is possible to 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, is not departing from the situation of the scope of the present invention
Under, various improvement can be carried out to it and part therein can be replaced with equivalent.Especially, as long as in the absence of structure punching
Prominent, the every technical characteristic being previously mentioned in each embodiment can combine in any way.The invention is not limited in text
