In the present embodiment, delay device 340 is to be connected with last driven cleaning wheel 320.Internal layer control of dust wheel 330 is with initiatively cleaning wheel 310 and driven cleaning wheel 320 contact; and make active cleaning wheel 310 and driven cleaning wheel 320 between internal layer control of dust wheel 330, and the particulate on active cleaning wheel 310 and the driven cleaning wheel 320 can be transferred on the internal layer control of dust wheel 330.
In first preferred embodiment of the present invention, roller type cleaning mechanism 300a comprises two the initiatively driven cleaning wheel of cleaning wheels 310, two 320, one group of internal layer control of dust wheel 330 and one delay device 340.In detail, internal layer control of dust wheel 330 comprises one first internal layer control of dust wheel, 332 and 1 second internal layer control of dust wheel 334, and first internal layer control of dust wheel 332 contact with driven cleaning wheel 320, and the second internal layer control of dust is taken turns 334 and contacted with active cleaning wheel 310.Initiatively cleaning wheel 310 and driven cleaning wheel 320 have one first sticky stuff 310a.Therefore, when plate 400 is wedge shape LGP 400a, the surface that cleaning wheel 310 and corresponding driven cleaning wheel 320 can contact wedge shape LGP 400a initiatively is to remove the particulate on the wedge shape LGP 400a.
Because internal layer control of dust wheel 330 has one second sticky stuff 330a; and the stickiness of the second sticky stuff 330a is greater than the stickiness of the first sticky stuff 310a; therefore; when first internal layer control of dust wheel 332 and second internal layer control of dust wheel 334 contact driven cleaning wheel 320 with active cleaning wheel 310 respectively; initiatively the particulate on the cleaning wheel 310 can be transferred on the second internal layer control of dust wheel 334, and the particulate on the driven cleaning wheel 320 can be transferred on the first internal layer control of dust wheel 332.
In the present invention, the material of the first sticky stuff 310a and the second sticky stuff 330a for example is control of dust film or other sticky stuff.And in a preferred embodiment of the present invention, in order to shorten the replacing time of the first sticky stuff 310a and the second sticky stuff 330a, the preferable material of the first sticky stuff 310a and the second sticky stuff 330a for example is to cut off formula control of dust film.
Holding above-mentioned, used herein delay device 340 for example is damper (damper), extension spring (draw spring), pneumatic cylinder, hydraulic cylinder or other mechanism that can make driven cleaning wheel 320 delay to reset.
When wedge shape LGP 400a was placed among the roller type cleaning mechanism 300a, initiatively cleaning wheel 310 was suitable for along the rotation of direction shown in the arrow 312, moved to drive wedge shape LGP 400a.When wedge shape LGP 400a was moved between active cleaning wheel 310 and the driven cleaning wheel 320, driven cleaning wheel 320 can be pressed on the surface 402 of wedge shape LGP 400a, and made wedge shape LGP 400a and corresponding active cleaning wheel 310 contacts.Then, initiatively cleaning wheel 310 can move by drive wedge shape LGP 400a.Because the thickness difference at wedge shape LGP 400a two ends, so the driven cleaning wheel 320 that contacts with wedge shape LGP 400a can be lifted gradually along with moving of wedge shape LGP 400a.It should be noted that, at wedge shape LGP 400a by after between cleaning wheel 310 initiatively and the corresponding driven cleaning wheel 320, the driven cleaning wheel 320 of connection delay mechanism 340 can be subjected to delay device 340 and support, and can not be pressed on the wedge shape LGP 400a, therefore, the present invention can avoid wedge shape LGP 200 to be subjected to driven cleaning wheel 120 effects (thrust F downwards) and the phenomenon of perk, and then avoids the problem of wedge shape LGP 200 scratches.
In another embodiment of the present invention; roller type cleaning mechanism 300a may further include one group of outer controls of dust wheel 350 that contact with first internal layer control of dust wheel, 332 and second internal layer control of dust wheel 334, and the particulate on first internal layer control of dust wheel, the 332 and second internal layer control of dust wheel 334 can be transferred to this and organizes outer control of dust and take turns on 350.Particularly, outer control of dust wheel 350 comprises one first outer control of dust wheel 352 and 1 second outer control of dust wheel 354, and first outer control of dust the wheel 352 and second outer control of dust wheel 354 all has one the 3rd sticky stuff 350a, and the stickiness of the 3rd sticky stuff 350a is greater than the stickiness of the second sticky stuff 330a.When contacting the first internal layer control of dust respectively, the first outer control of dust wheel 352 and the second outer control of dust wheel 354 take turns the 332 and second internal layer control of dust when taking turns 334; particulate on the first internal layer control of dust wheel 332 can be transferred on the first outer control of dust wheel 352, and the particulate on the second internal layer control of dust wheel 334 can be transferred on the second outer control of dust wheel 354.In the same manner, the material of the 3rd sticky stuff 350a can be control of dust film (as cutting off formula control of dust film) or other sticky stuff.
Because the stickiness minimum of the first sticky stuff 310a; and the stickiness maximum of the 3rd sticky stuff 350a; therefore; particulate on the wedge shape LGP 400a can be transferred to the second sticky stuff 330a on the internal layer control of dust wheel 330 from the first sticky stuff 310a on active cleaning wheel 310 and the driven cleaning wheel 320; then, transfer to the 3rd sticky stuff 350a on the outer control of dust wheel 350.It should be noted that, because roller type cleaning mechanism 300a has internal layer control of dust wheel 330 and outer control of dust wheel 350, therefore, when outer control of dust wheel 350 must clean, internal layer control of dust wheel 330 still can continue action that wedge shape LGP 400a is cleaned.In other words, the present invention can carry out the cleaning of control of dust wheel under non-stop-machine situation.
Shown in Fig. 2 A, roller type cleaning mechanism 300a can further comprise a feeding web 360a and a discharging conveyer belt 360b.Wherein, feeding web 360a is suitable for carrying plate 400 to active cleaning wheel 310 and driven cleaning wheel 320, and discharging conveyer belt 360b is suitable for carrying plate 400 away from active cleaning wheel 310 and driven cleaning wheel 320.
Fig. 2 B illustrates the schematic diagram into the roller type cleaning mechanism of second embodiment of the invention, and Fig. 2 C illustrates the schematic diagram into the roller type cleaning mechanism of third embodiment of the invention.Please also refer to Fig. 2 A, Fig. 2 B and Fig. 2 C.The structure of roller type cleaning mechanism 300b, 300c among Fig. 2 B and Fig. 2 C is identical with the roller type cleaning mechanism 300a shown in Fig. 2 A haply, and its difference is: the quantity of cleaning wheel 310, driven cleaning wheel 320, internal layer control of dust wheel 330 and outer control of dust wheel 350 initiatively.In addition, the connected mode of each member is identical with first embodiment among roller type cleaning mechanism 300b, the 300c, does not give unnecessary details at this.By among Fig. 2 A, Fig. 2 B and Fig. 2 C as can be known, the quantity of the active cleaning wheel 310 among roller type cleaning mechanism 300a, 300b, the 300c, driven cleaning wheel 320, internal layer control of dust wheel 330 and outer control of dust wheel 350 can adjust on demand, to improve the cleaning efficiency of roller type cleaning mechanism 300a, 300b, 300c.
It should be noted that, roller type cleaning mechanism 300a, 300b in the present embodiment, 300c are not limited in use at wedge shape LGP 400a, and it is more applicable to printed circuit board (PCB), flexible printed circuit, plastic foil, Polarizer, backlight or other panel.In addition, roller type cleaning mechanism 300a is not limited in and includes only a delay device 340, and roller type cleaning mechanism 300a more can comprise a plurality of delay devices 340, so that a plurality of driven cleaning wheel 320 all can delay to reset.In addition, initiatively the quantity of cleaning wheel 310, driven cleaning wheel 320 and internal layer control of dust wheel 330 is not limited in the quantity described in the foregoing description.
Moreover the quantity of outer control of dust wheel 350 can be not limited only to the quantity described in the foregoing description, and its quantity can be one or more.For instance, when plate 400 was kept flat, the upper surface of plate 400 was easier to gather particulate, and therefore, the quantity of outer control of dust wheel 350 can be one, to keep the stickiness of the second sticky stuff 330a on the first internal layer control of dust wheel 332.Perhaps, the quantity of outer control of dust wheel 350 can be for more, so that roller type cleaning mechanism 300c can have preferable cleaning efficiency for the particulate on the plate 400.
In sum, because roller type cleaning mechanism of the present invention has following advantage:
1. because roller type cleaning mechanism of the present invention has internal layer control of dust wheel and outer control of dust wheel, therefore, when outer control of dust wheel must clean, the action that internal layer control of dust wheel still cleans plate and cleaning wheel sustainably.
2. because the present invention's roller type cleaning mechanism has the delay device that can avoid the plate perk, therefore, after the cleaning of plate (wedge shape LGP), be difficult for having the problem generation of scratch through cleaning wheel initiatively and corresponding driven cleaning wheel.
