Embodiment
Below coordinate graphic and Reference numeral to do more detailed description to embodiments of the present invention, those of ordinary skill in the art can be implemented according to this after studying this instructions carefully.
Alignment cloth detection method provided by the present invention, performed by a vibration board, therefore, will first be described with reference to the structure of Fig. 1 and Fig. 2 to the vibration board used in present pre-ferred embodiments below.
Fig. 1 is for showing the stereographic map of the vibration board used in present pre-ferred embodiments, and Fig. 2 is for showing the side view of the vibration board used in present pre-ferred embodiments.As shown in Figure 1 and Figure 2, vibration bench structure provided by the present invention, includes: base 10, worktable 20 and an at least one Vib. 40.
Worktable 20 is a rectangular plate body, and it has a smooth working surface 201, is provided with placing an alignment cloth 9 to be detected.Worktable 20 is flatly arranged on the base 40 it by having mutually level multiple syndeton 30.More particularly, each syndeton 30 all comprises one first Connection Block 31,1 second Connection Block 32 and a bump leveller 33.First Connection Block 31 is arranged on base 10, and the second Connection Block 32 is arranged on a bottom surface 202 of worktable 20, and the first Connection Block 31 links through a bump leveller 33 and the second Connection Block 32.As shown in Figure 1 and Figure 2, bump leveller 33 does not directly contact with the first Connection Block 31 and the second Connection Block 32, and is through screw rod and is fixed in the middle of the first Connection Block 31 and the second Connection Block 32 and the position of both certain distances of distance respectively.In addition, although in FIG, only arrange four syndetons 30, but the quantity of syndeton 30 is not limited to this between worktable 20 and base 10, user can configure applicable quantity according to demand.
Described Vib. 40 can be a vibrating motor, and it contacts with worktable 20.In the preferred embodiment, vibration bench structure has multiple Vib. 40, and described Vib. 40 is directly fixed on the bottom surface 202 of worktable 20.
Fig. 3 is the process flow diagram of display according to the alignment cloth detection method of preferred embodiment of the present invention, and Fig. 4 A to Fig. 4 B is that display is according to schematic perspective view during method detection alignment cloth provided by the present invention.Hereinafter, based on the structure of above-mentioned vibration board, Fig. 3, Fig. 4 A and Fig. 4 B is coordinated to be described for alignment cloth detection method provided by the present invention.
As described in Figure 3, in step S31, first, first alignment cloth 9 to be detected is placed on the working surface 201 of worktable 20; Then, in step s 32, one mao is placed on alignment cloth 9 to detection piece 50.The hair used in present pre-ferred embodiments to detection piece 50 for having a plate body of copper coin size, and its shape is preferably circular, because stressed the most even when the shape of circle is on alignment cloth 9, the direction of hair to detection piece 50 movement can not be had influence on because of unbalance stress.Shown by Fig. 4 A is schematic perspective view during execution step S31 and S32.
After step S32, perform step S33, start the Vib. 40 that is arranged on the bottom surface 202 of worktable 20, with shaking table 20 and the alignment cloth 9 that is placed on working surface 201.Along with the vibration of alignment cloth 9, be placed on hair on alignment cloth 9 to detection piece 50 can hair on alignment cloth 9 to movement, as shown in Figure 4 B.Because the syndeton 30 between worktable 20 and base 10 is provided with bump leveller 33, therefore, the vibration of worktable 20 can't be passed to base 10.Finally, along with hair performs step S34 to the mobile of detection piece 50, observe hair to the moving direction of detection piece 50 on alignment cloth 9, thus judge that the hair of alignment cloth 9 is to the demand whether meeting mechanical friction orientation processing procedure.If find that there is the alignment cloth of the demand of not meeting in step S34, just can be eliminated, in the processing procedure of liquid crystal panel, be had influence on the quality of panel to avoid hair to the alignment cloth not meeting demand.
In addition, as shown in Fig. 1 and Fig. 4 B, the side of the worktable 20 of vibration board is provided with one mao further to angle measurement device 21.The hair that hair can coordinate hair to measure alignment cloth 9 to detection piece 50 to angle measurement device 21 to angle.More specifically, hair to angle measurement device 21 for being arranged on an angle measurement scale of the side of the working surface 21 of worktable 20.In above-mentioned step S34, operator can when observing hair to the vibration moving direction on alignment cloth 9 of detection piece 50 along with vibration board, coordinate hair to angle measurement device 21 judge the hair of alignment cloth 9 to rough angle.
The above is only embodiments of the invention and exemplary applications thereof, when unavailable to limit the enforceable scope of the present invention, and any those of ordinary skill in the art various improvement that can complete according to present disclosure and change, all should be considered as not departing from flesh and blood of the present invention and be covered by hereafter in institute's claim.Everyly utilize present disclosure and institute's accompanying drawings and the equivalent structure reached, no matter be directly or indirectly be applied to this area or other correlative technology field, all should be considered as belonging in claim of the present invention.
