The specific embodiment
Below in conjunction with accompanying drawing, the utility model 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 highly to regulate part 140, third high degree to regulate part 150, the 4th highly to 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 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 rotation on LGP 20, form light guide structure, 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 to regulate part 140 to be connected to the two ends of the first rotating shaft 111, regulates height and the gradient of the first rotating shaft 111.Can be in the situation that first highly regulate part 130 and second to regulate the height of part 140 to make the height that the first rotating shaft 111 is changed in identical change.If first highly regulates part 130 and second highly to regulate part 140 not make the height of the first rotating shaft 111 2 sides make in the situation of identical change, 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 to regulate part 140 can regulate separately respectively the height of the first rotating shaft 111 1 sides.
Third high degree regulates part 150 and the 4th highly to regulate part 160 to be connected to the two ends of the second rotating shaft 121, regulates height and the gradient of the second rotating shaft 121.Make third high degree regulate part 150 and the 4th highly to regulate part 160 to make in the situation of identical change here, only change the height of the second rotating shaft 121.And third high degree rotating shaft 150 and the 4th 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.When third high degree regulates part 150 and the 4th, highly regulate part 160 to 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 regulates part 150 and the 4th highly to regulate part 160 can regulate separately respectively the height of the second rotating shaft 121 1 sides.
Highly regulate the change of part 130,140,150,160 height that the distance between the first nip drum 110 and the second nip drum 120 is also changed.
Referring to Fig. 3, illustrate that the height that is applied to LGP manufacture of the present utility model regulates the formation of part.
Highly regulate part 130,140,150,160 to combine, in Fig. 3 by highly to regulate first in part 130,140,150,160 highly to regulate part 130 to describe.
As shown in Figure 3, first highly regulates part 130 to comprise 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, by rotation rotary body 132, regulate height.Here, according to the direction of rotation of rotary body 132, the height of connector 131 can rise or decline.
The inside of fixture 134 is provided 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, to being applied to the lash adjusting device of LGP manufacture, regulate the method in the gap between nip drum to describe.
As shown in Figure 4, first judge LGP 20 above with whether parallel below.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 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, the first nip drum 110 and the distance between the second nip drum 120 (being L1 below) that compare lash adjusting device 100, judgement should regulate the distance L 1 between the first nip drum 110 and the second nip drum 120 or not.
According to the S120 stage, the in the situation that of 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 regulate part 130 and second highly to regulate part 140 to regulate the height of the first nip drum 110 by first, also can regulate part 150 and the 4th highly to regulate part 160 to regulate the height of the second nip drum 120 by third high degree, 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 regulate the height of the first nip drum 110 and the height of the second nip drum 120 to regulate the distance L 1 between the first nip drum 110 and the second nip drum 120 simultaneously.
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 regulates 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 that regulates 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, judges 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.
