Through experiment test, can obtain, adopt in prior art the method coating sealed plastic box time used to be as shown in Figure 1 about 3 minutes 12 seconds, adopt in prior art the method coating sealed plastic box time used to be as shown in Figure 2 about 3 minutes, and adopt the method coating sealed plastic box time used as shown in Figure 5 that the embodiment of the present invention provides to be about 2 minutes 40 seconds, can find out, the coating process of the above-mentioned sealed plastic box that the embodiment of the present invention provides can reduce the coating time of sealed plastic box effectively, improves the coating efficiency of sealed plastic box.And when the quantity of the viewing area on substrate is more, the said method that the embodiment of the present invention provides is more obvious in the effect improving aspect the coating efficiency of sealed plastic box.
Preferably, in order to guarantee the uniformity of the sealed plastic box that the to be coated region of nozzle on substrate is coated with, each nozzle is greater than the second sealed plastic box coating speed in the region of this nozzle the intersection region except horizontal coating line and longitudinal coating line at the first sealed plastic box coating speed of the intersection region of horizontal coating line and longitudinal coating line.
Particularly, as shown in Figure 5, take and be longitudinally coated with nozzle 2 as example describes, be longitudinally coated with nozzle 2 the horizontal horizontal coating line X7 of coating line X0-and longitudinal coating line Y1, longitudinally the first sealed plastic box coating speed of the intersection region of coating line Y2 to be set to be greater than the region of longitudinal coating nozzle 2 beyond in this intersection region be the horizontal coating line X7 of horizontal coating line X0-and longitudinal coating line Y1, longitudinal the second sealed plastic box coating speed of the non-intersection region of coating line Y2.If the first sealed plastic box coating speed is identical with the second sealed plastic box coating speed, horizontal coating line and longitudinally the intersection region of coating line can too much follow-up, cause the even problem of box thickness ununiformity after to box technique because of the amount of the sealed plastic box of coating, therefore, non-intersection region with respect to horizontal coating line and longitudinal coating line, the coating speed that need to improve sealed plastic box when laterally the intersection region of coating line and longitudinal coating line is coated with sealed plastic box, this coating speed can show as the translational speed of respective girders or longeron.
Preferably, the first sealed plastic box coating speed and the ratio of the second sealed plastic box coating speed can be controlled to 1.1-1.3:1.Best, the first sealed plastic box coating speed and the ratio of the second sealed plastic box coating speed can be controlled to 1.2:1.
The coating process of a kind of sealed plastic box that the embodiment of the present invention provides, utilize a plurality of nozzles longitudinally coating line and horizontal coating line each coating sealed plastic box in region to be coated on substrate, owing to adopting the mode of nozzle vertical and horizontal intersection coating sealed plastic box, like this, in the coating path of nozzle, there is not turning, avoided the even problem of sealed plastic box crawling producing due to turning.And, by controlling the coating opportunity of each crossbeam and each longeron, in crossbeam and the longeron coating sealed plastic box of advancing be independent of each other in the situation that walks, can reduce like this coating time of sealed plastic box, improve the coating efficiency of sealed plastic box.
Obviously, those skilled in the art can carry out various changes and modification and not depart from the spirit and scope of the present invention the present invention.Like this, if within of the present invention these are revised and modification belongs to the scope of the claims in the present invention and equivalent technologies thereof, the present invention is also intended to comprise these changes and modification interior.
