Abstract
A clearance adjusting device applied to manufacture of light guide plates comprises a first pressing roller, a second pressing roller and a clearance adjusting device. The clearance adjusting device adjusts a clearance between the first pressing roller and the second pressing roller, and is connected to two ends of a first rotating shaft of the first pressing roller. By the clearance adjusting device, the problem that because the clearance between the pressing rollers is smaller than the thickness of each light guide plate, the light guide plates crack when pressed by the pressing rollers can be solved; and owing to adjustment of the clearance, the uniformity of light guide structures on the light guide plates is high.

The specific embodiment
Below in conjunction with accompanying drawing, the present invention is described in detail.
As shown in Figure 2, lash adjusting device 100 comprises the first nip drum 110, the second nip drum 120, slack adjuster, and slack adjuster comprises that first highly regulates part 130, second and highly regulate part 140, third high degree and regulate part 150, the 4th and highly regulate part 160.Although do not show in Fig. 2, the first nip drum 110 can make LGP 20 form catoptric arrangement, and the second nip drum can make LGP 20 form many photo structures.The first nip drum 110 and the second nip drum 120 are that the mode by punching press makes the LGP surface form light guide structure.
Thereby the first nip drum 110 forms light guide structure in rotation centered by the first rotating shaft 111 on LGP 20.Here the first nip drum 110 is with the opposite spin of the second nip drum 120.
Thereby the second nip drum 120 take the second rotating shaft 121 centers as the rotation form light guide structure on LGP 20, here the second nip drum 120 is with the opposite spin of the first nip drum 110.
First highly regulates part 130 and second highly regulates the two ends that part 140 is connected to the first rotating shaft 111, regulates height and the gradient of the first rotating shaft 111.Can be in the situation that the first height of highly regulating part 130 and the second adjusting part 140 be made the height of identical change change the first rotating shaft 111.Highly regulate the height that part 140 do not make the first rotating shaft 111 2 sides and make in the situation of identical change if first highly regulates part 130 and second, the height of the first rotating shaft 111 and gradient can together with change.That is to say, first highly regulates part 130 and second highly regulates part 140 and can regulate separately respectively the height of the first rotating shaft 111 1 sides.
The third high degree is regulated part 150 and the 4th and is highly regulated the two ends that part 160 is connected to the second rotating shaft 121, regulates height and the gradient of the second rotating shaft 121.Make third high degree adjusting part 150 and the 4th highly regulate part 160 here and make in the situation of identical change, only change the height of the second rotating shaft 121.And third high degree rotating shaft 150 and the 4th the height rotating shaft 160 make, in the situation of the second rotating shaft 121 Level Changes, also can change the gradient of the second rotating shaft 121.Highly regulate part 160 when third high degree adjusting part 150 and the 4th and make respectively different Level Changes, while making the second rotating shaft 121 Level Change, the gradient of the second rotating shaft 121 will change.That is to say, third high degree adjusting part 150 and the 4th is highly regulated part 160 and can be regulated separately respectively the height of the second rotating shaft 121 1 sides.
The change of highly regulating part 130,140,150,160 height makes the distance between the first nip drum 110 and the second nip drum 120 also change.
Referring to Fig. 3, the height adjusting formation partly that LGP is manufactured that is applied to of the present invention is described.
Highly regulating part 130,140,150,160 can combine, and in Fig. 3, will highly regulate part 130 and describe highly to regulate first in part 130,140,150,160.
As shown in Figure 3, first highly regulates part 130 comprises connector 131, rotary body 132, motor 133 and fixture 134.
The bolt of the upper end of rotary body 132 for matching with screwed hole 131a, and be connected with the screwed hole 131a on connector 131, height regulated by rotation rotary body 132.Here, according to the direction of rotation of rotary body 132, the height of connector 131 can rise or descend.
The inside of fixture 134 is equipped with bearing 134a, and it is upper that rotary body 132 is sleeved on bearing 134a, and be arranged on fixture 134 by bearing 134a, and rotary body 132 can be around self axis rotation.
Below with reference to Fig. 4, the method for the lash adjusting device that is applied to the LGP manufacture being regulated to the gap between nip drum describes.
As shown in Figure 4, at first judge the top and following whether parallel of LGP 20.Here, lash adjusting device 100 utilizes the various sensors such as UV sensor to judge that whether the top and bottom of LGP 20 are parallel.And the user also can with the naked eye judge the whether parallel of LGP top and bottom.
According to the S110 stage, in the situation that the top and bottom of LGP 20 are parallel, compare the first nip drum 110 and the distance between the second nip drum 120 (following is L1) of lash adjusting device 100, judgement should be regulated the distance L 1 between the first nip drum 110 and the second nip drum 120 or not.
According to the S120 stage, in the situation that adjustable range L1, lash adjusting device 100 is adjusted to by the distance L 1 of 120 of the first nip drum 110 and the second nip drums the height (hereinafter referred to as L3) that the height L2 with LGP adapts.According to the S130 stage, Height Adjustment, to L3, in general height L3 and height L2 are identical, certainly also can decide height L3 according to the first nip drum 110 or the formed light guide structure of the second nip drum 120 punching press.
At this moment, lash adjusting device 100 can highly be regulated part 130 and second by first and highly regulate the height that part 140 is regulated the first nip drum 110, also can regulate part 150 and the 4th by the third high degree and highly regulate the height that part 160 is regulated the second nip drum 120, thereby regulate the distance L 1 between the first nip drum 110 and the second nip drum 120.
Lash adjusting device 100 can be by regulating the first nip drum 110 simultaneously height and the height of the second nip drum 120 regulate the distance L 1 between the first nip drum 110 and the second nip drum 120.
According to the S140 stage, the first nip drum 110 and the second nip drum 120 stamp out light guide structure on LGP 20, print off the LGP 20 with light guide structure afterwards.
According to the S120 stage, if do not adjust distance L 1, the first nip drum 110 and the second nip drum 120 stamps out light guide structure according to the S140 stage on LGP 20, print off the LGP 20 with light guide structure.
According to the S110 stage, if the top and bottom of LGP 20 are not parallel, lash adjusting device 100 is regulated the angle S150 between the first nip drum 110 and the second nip drum 120 according to the depth of parallelism of the top and bottom of LGP 20, that is to say the gradient of regulating the first nip drum 110 and the second nip drum 120, the first nip drum 110 and the second nip drum 120 are parallel to each other with two surfaces of LGP respectively.
Afterwards, lash adjusting device 100 is according to the S120 stage, the distance L 1 between the first nip drum 110 and the second nip drum 120 relatively, and the height L2 of LGP, judge whether to regulate the distance L 1 of 120 of the first nip drum 110 and the second nip drums.Here, distance L 1 between the first nip drum 110 and the second nip drum 120 can decide according to the angle that the S150 stage is adjusted, L1 equals longest distance or the beeline between uneven the first nip drum 110 and the second nip drum 120, the height L2 of LGP equals longest distance or the beeline between the top and bottom of uneven LGP, that is to say in the S130 stage distance L 3 of 120 of the first nip drum 110 and the second nip drums is adapted with the height L2 of LGP.
