Abstract

An embodiment of the utility model discloses a base station after printing, which belongs to the technical field of liquid crystal display manufacture. The base station after printing settles a technical problem of non-uniform PI distribution because of partial recess of a glass substrate. The base station after printing comprises a plurality of liftable push rods which are inserted into a tabletop. The push rods are used for jacking up the glass substrate on the base station. The base station according to the utility model is used for improving the base station after printing.

Description

Printing back base station

Technical field

The utility model belongs to LCD manufacturing technology field, is specifically related to a kind of printing back base station.

Background technology

Along with the continuous development of electronic technology, LCD has become modal display device.In the manufacture process of LCD, on glass substrate, print polyimide (Polyimide; PI), get into printing back base station afterwards.As shown in Figure 1, the pressure pin 2 of base station 1 both sides stretches out, and common every side has six pressure pins 2, and glass substrate 3 is held up, and by mechanical arm glass substrate 3 is taken away from base station 1 then.

The inventor finds that there is following problem at least in prior art: glass substrate is extremely thin in the process that realizes the utility model, be prone to deformation takes place, and pressure pin only holds up the both sides of glass substrate, so cause the middle part of glass substrate to lower recess.Just be printed on the PI uncured also on the glass substrate, PI will flow to recess, causes the PI skewness, and in the part that pressure pin holds up, PI is just very thin, thereby has influenced the quality of product.

The utility model content

The utility model embodiment provides a kind of printing back base station, has solved prior art because the glass substrate local dent causes PI technical matters pockety.

For achieving the above object, the embodiment of the utility model adopts following technical scheme:

This printing back base station comprises the some liftable push rods that are embedded on the table top, and said push rod is used for the glass substrate on the said base station of jack-up.

When glass substrate just had been placed on the base station, push rod was embedded in base station inside, height such as its top and base station surface, or be lower than the base station surface; In the time of need taking glass substrate away, push rod rises, and the jack-up glass substrate is taken away glass substrate by mechanical arm.

Compared with prior art; The technique scheme that the utility model provided has following advantage: utilize push rod; Stressed even in the time of can making glass substrate by jack-up, need only thickness and rigidity according to glass substrate, the push rod of suitable density is set; Can avoid glass substrate generation local dent, thereby solve prior art because the glass substrate local dent causes PI technical matters pockety.

Description of drawings

In order to be illustrated more clearly in the utility model embodiment or technical scheme of the prior art; To do to introduce simply to the accompanying drawing of required use in embodiment or the description of the Prior Art below; Obviously, the accompanying drawing in describing below only is some embodiment of the utility model, for those of ordinary skills; Under the prerequisite of not paying creative work, can also obtain other accompanying drawing according to these accompanying drawings.

Fig. 1 is the vertical view of existing printing back base station;

Fig. 2 is the side view of base station after the printing that embodiment provided of the utility model;

Fig. 3 is the vertical view of base station after the printing that embodiment provided of the utility model.

Embodiment

To combine the accompanying drawing among the utility model embodiment below, the technical scheme among the utility model embodiment is carried out clear, intactly description, obviously, described embodiment only is the utility model part embodiment, rather than whole embodiment.Based on the embodiment in the utility model, the every other embodiment that those of ordinary skills are obtained under the prerequisite of not paying creative work belongs to the scope that the utility model is protected.

As shown in Figures 2 and 3, base station 1 after the printing that the utility model embodiment is provided comprises the some liftable push rods 4 that are embedded on the table top, and push rod 4 is used for the glass substrate 3 on the jack-up base station 1.

Glass substrate 3 just has been placed on 1 last time of base station, and push rod 4 is embedded in base station 1 inside, its top and base station 1 surface height such as grade, or be lower than base station 1 surface; In the time of need taking glass substrate 3 away, push rod 4 rises, and jack-up glass substrate 3 is taken away glass substrate 3 by mechanical arm again.Push rod 4 can be provided with the time of automatic rise and decline through computer, also can manually be controlled by operating personnel.Utilize push rod 4; Stressed even in the time of can making glass substrate 3 by jack-up; As long as thickness and rigidity according to glass substrate 3; The push rod 4 of suitable density is set, can avoids glass substrate 3 that local dent takes place, thereby solve prior art because the glass substrate local dent causes PI technical matters pockety.

Among the utility model embodiment, push rod 4 is arranged with the form of array.As a preferred version, the quantity of push rod 4 is 24, be 4 row, 6 row and arrange, and the spacing of push rod 4 is preferably 5cm.Arrange push rod 4 with equally spaced box formation, the arrangement that makes push rod 4 evenly, neat, so when more effectively guaranteeing glass substrate 3 by jack-up stressed evenly.In addition, push rod 4 is arranged in rule, neat square formation, the action of mechanical arm after also being convenient to.

Among the utility model embodiment, push rod 4 is cylindrical, and the diameter of push rod 4 is preferably 1mm.Columniform push rod 4 is circular with the surface of contact of glass substrate 3, so the security of glass substrate 3 is higher; And the surface of contact of square column type push rod and glass-based 3 plates is square, and cut is caused to glass substrate 3 easily in four then square angles, and risk is higher relatively.

Among the utility model embodiment, the position of push rod 4 is corresponding to the marginarium on the glass substrate 3.The marginarium is exactly a glass substrate 3 when finally being made into LCD, is positioned at the edge of display, and is not used in the zone of display image.The surface of contact of push rod 4 and glass substrate 3 is arranged on the marginarium,, also can influence the final display quality of LCD, further reduced the risk that substandard products occur even 4 pairs of glass substrates 3 of push rod have caused cut or other damages.

The above; Be merely the embodiment of the utility model; But the protection domain of the utility model is not limited thereto; Any technician who is familiar with the present technique field is in the technical scope that the utility model discloses, and the variation that can expect easily or replacement all should be encompassed within the protection domain of the utility model.Therefore, the protection domain of the utility model should be as the criterion with the protection domain of claim.
