Embodiment
In order to make the purpose , technical scheme and advantage of the present invention be clearer, with reference to the accompanying drawings and embodiments, it is right
The present invention is further described.It should be appreciated that the specific embodiments described herein are merely illustrative of the present invention, and do not have to
It is of the invention in limiting.
Embodiment one
With reference to shown in Fig. 1, the liquid crystal panel adsorbent equipment of the present embodiment mainly includes supporting table 10, sets in supporting table 10
Multiple absorbing units 20 and solenoid valve, supporting table 10 is used for bearing liquid crystal display panel, and supporting table 10 includes 11 He of central area
The fringe region 12 set around central area 11, wherein in central area 11 and fringe region 12 is equipped with multiple absorbing units
20.The solenoid valve is used for absorbing unit 20 of the control successively in the central area 11 and in fringe region 12
Absorbing unit 20 adsorbs liquid crystal panel.In this way, absorption to the center section of liquid crystal panel and to liquid crystal panel peripheral portion
Absorption has the regular hour poor, is conducive to all discharge the gas below liquid crystal panel, ensures the flat of liquid crystal panel absorption
Whole property.
As the presently preferred embodiments, the area of fringe region 12 is more than the area of central area 11.Due to the work of self gravitation
With the center section of liquid crystal panel is sagging, and the degree of crook of center section is larger, in contrast the peripheral portion of liquid crystal panel
Tilt upward, and the degree of crook of peripheral portion is smaller.The central area of supporting table 10 is reduced, when to the pars intermedia of liquid crystal panel
When point first being absorbed, it may be such that the gas below the center section of liquid crystal panel is discharged as far as possible.If the area of central area
It is excessive, though the peripheral portion of liquid crystal panel absorption and liquid crystal panel center section absorption existence time it is poor, liquid crystal surface
Gas between plate and supporting table 10 may also not exclude completely.
Further, central area 11 is central symmetric segment using 10 midpoint of supporting table as symmetric points, fringe region 12
For the central symmetric segment using 10 midpoint of supporting table as symmetric points, so that the gas in central area 10 from surrounding equably
Spread to fringe region 11 so that the gas in fringe region 11 is equably spread from surrounding to supporting table 10 so that liquid crystal surface
Other below plate drain as far as possible, are conducive to the planarization of liquid crystal panel absorption.
As the presently preferred embodiments, central area 11 is border circular areas, and fringe region 12 is using 10 midpoint of supporting table as geometry
The circle ring area at center.Wherein, the arc length such as multiple absorbing units 20 in central area 11 is distributed in supporting table
10 midpoints is on the circumference in the center of circle.The arc length such as multiple absorbing units 20 in fringe region 12 are distributed in supporting table
10 centers is on the circumference in the center of circle.This ensure that liquid crystal panel center section and the uniform of liquid crystal panel peripheral portion are inhaled
It is attached so that the regional of liquid crystal panel is more smooth.The discharge of liquid crystal panel underlying gas is also beneficial at the same time, avoids liquid crystal
Bulge is produced between panel and supporting table 10, ensures absorption planarization, and then influences to apply film uniformity.
As embodiment, adsorption hole that absorbing unit 20 includes being arranged in supporting table 10, be arranged in supporting table 10 and
The vacuum pipe of adsorption hole connection and and the vacuum pump that is connected with vacuum pipe, the working status of solenoid valve control vacuum pump,
And then control absorption of the adsorption hole to liquid crystal panel.By setting the control command of solenoid valve, realization is pointed to central area 11
The control successively of interior absorbing unit 20 and the absorbing unit 20 in fringe region 12 so that the gas below liquid crystal panel
Drain as far as possible, improve the absorption planarization of liquid crystal panel.
Further, multiple vacuum pipes 22 of multiple absorbing units 20 in central area 11 connect, positioned at side
Multiple vacuum pipes connection of multiple absorbing units 20 in edge region 12.It is located at multiple absorption lists in central area 11
Member 20 shares same vacuum pump, and multiple absorbing units 20 in fringe region 12 share another vacuum pump, on the one hand
The convenient control adsorbed to central area 11 and fringe region 12, is on the other hand conducive to save equipment cost.
Embodiment two
As indicated with 2, the present embodiment two and embodiment one are a difference in that：Central area 11 is square area, is located at
The quantity of absorbing unit 20 in central area 11 is four, and four absorbing units 20 are located at centered on 10 midpoint of supporting table
On four angles of square, such four absorbing units 20 are uniformly distributed, and ensure that to the equal of liquid crystal panel center section absorption
Even property.Further, multiple absorbing units 20 in fringe region 11 are distributed in the square centered on 10 midpoint of supporting table
Frame on, ensure that to liquid crystal panel peripheral portion absorption uniformity.It should be noted that the center in the present embodiment
Domain 11 and fringe region 11 collectively form the bearing area overlapping with liquid crystal panel.
A kind of liquid crystal panel adsorbent equipment disclosed by the invention, by setting multiple absorbing units in supporting table, will prop up
Support platform is divided into central area and fringe region, and the absorbing unit in central area and fringe region successively carries out liquid crystal panel
Absorption so that the gas below liquid crystal panel is discharged as far as possible, improves absorption planarization, reduces fragmentation possibility.
The embodiment of the present invention is described in detail above, although having show and described some implementations
Example, it will be understood by those skilled in the art that limiting the of the invention of its scope by claim and its equivalent not departing from
In the case of principle and spirit, it can modify to these embodiments and perfect, these are changed and improve also should be in the present invention
Protection domain in.
