Because in the most technological processes that relate in the production process of LCD, need to adopt two air knifes 1 simultaneously the upper surface and the lower surface of glass substrate to be dried up operation, therefore, gas outlet that usually can 1, two air knife 1 of two air knifes of upper and lower settings between the support 2 is parallel and be positioned at different horizontal planes.Accordingly, the corresponding slider track 22 of the same end of two air knifes 1, and the moving slider 23 of two air knifes 1 is provided with the both sides of corresponding slider track 22 respectively.Because the situation of two air knifes 1 of upper and lower settings is most widely used in the production process of LCD between the support 2, therefore, be that example describes still below with the situation of two air knifes 1 between the support 2, but not with this as to restriction of the present utility model.
As preferred embodiment, the main part of slider track 22 can be that the cross section is rectangular cylinder, is respectively arranged with the track that slides up and down for moving slider 23 on two relative sides of cylinder.All be provided with a moving slider 23 on the track of each side of cylinder, the part that moving slider 23 is connected with track is complementary with the shape of raceway surface.Each moving slider 23 is connected with air knife 1 one ends on the place support 2, the two ends of each air knife 1 connect a moving slider 23 respectively, vertically move up and down simultaneously under the drive of both sides moving slider 23 with the two ends of realizing each air knife 1.
Further, compare and adopt driver element 5 directly to drive the embodiment of air knife 1, as another preferred embodiment, air knife 1 can corresponding driving section, the driving section is connected with moving slider 23, be used under the drive of driver element 5, promote moving slider 23 and slide up and down along place slider track 22 simultaneously, move in the vertical direction to drive corresponding air knife 1 two ends.Make control module more flexible, more accurate by the driving section to the control of air knife 1 horizontal level.
Concrete, the corresponding air knife 1 in driving section can comprise: two connecting rods 61, two circular drives pieces 62, drive link 63 and two oval drive blocks 64;
Wherein, the moving slider 23 that air knife 1 two ends connect connects a connecting rod 61 in vertical direction respectively, and connecting rod 61 bottoms are provided with a circular drives piece 62;
Drive link 63 is connected with driver element 5, and its two ends are separately positioned on base 21 tops of support 2, and the two ends of drive link 63 are provided with an oval drive block 64 respectively, and the described circular drives piece of each oval drive block 64 and 62 is tangent;
Drive link 63 rotates under the driving of driver element 5, drive oval drive block 64 rotations, oval drive block 64 promotes 62 rotations of tangent circular drives piece, and connecting rod 61 is moved down in vertical direction, drives the moving slider 23 that connects and slides up and down along slider track 22.
In each driving section, driver element 5 is driving drive link 63 rotations that are provided with between two bases 21 under the control of control module, the rotation of drive link 63 drives oval drive block 64 rotations of its both sides, because oval drive block 64 is tangent with the circular drives piece 62 of its top, and oval drive block 64 is irregular circles, when rotated, the edge that edge that radius is little and radius are big is alternately tangent with circular drives piece 62, thereby promote 62 rotations of circular drives piece, and circular drives piece 62 is in rotary course, the level height in its center of circle is along with the variation of the edge radius that contacts with oval drive block 64 changes, promptly when the little side edge of circular drives piece 62 and oval drive block 64 radiuses was touched, the level height at the place, the center of circle of circular drives piece 62 was relatively low; And when the big side edge of circular drives piece 62 and oval drive block 64 radiuses is touched, the level height at the place, the center of circle of circular drives piece 62 is higher relatively, therefore, promote in the process of circular drives piece 62 rotations at oval drive block 64, connecting rod 61 moves up and down under the drive of circular drives piece 62 in vertical direction, and connecting rod 61 is connected with moving slider 23, therefore, the rotation of the oval drive block 64 at drive link 63 two ends can drive moving slider 23 that air knife 1 two ends connect and slide up and down along the slider track 22 at place.
Further, owing to adopt oval drive block 64 to promote 62 rotations of circular drives piece, and then the mode of promotion moving slider 23, the sliding scale of moving slider 23 on slider track 22 is subjected to the restriction of oval drive block 64 and circular drives piece 62 diameters, therefore, the sliding scale of moving slider 23 on slider track 22 is limited.
