[embodiment]
Seeing also Fig. 1, is light guide plate of the present invention and reflector plate composite set schematic perspective view.It comprises a support frame 20, a workbench unit 10, an elevating mechanism 30 and two idler wheel mechanisms 40.
See also Fig. 2, this support frame 20 comprises a transverse slat 21 and two risers 22,23 that support this transverse slat, wherein, this transverse slat 21 has a threaded hole 211 and a plurality of unthreaded hole 212, this threaded hole 211 and unthreaded hole 212 run through the upper and lower surface of this transverse slat 21, and these riser 22,23 bottoms have concave indentation 221,231 to make things convenient for picking and placeing of device.
See also Fig. 3, this workbench unit 10 comprises a workbench 11 and two settings locating piece 12 thereon, wherein this workbench 11 comprises a location boss 113 and an a plurality of unthreaded hole 112, this positioning boss 113 is arranged on the edge of this workbench 11, these a plurality of unthreaded holes 112 on this workbench 11 with unthreaded hole 212 corresponding distributions, this locating piece 12 is fixed on this positioning boss 113 by bolt (indicate).
See also Fig. 4, this elevating mechanism 30 comprise a plurality of guide pillars 31, a plurality of guide pin bushing 34, a plurality of stop collar 33, two rise a spring 35 and a location bolt 32.
See also Fig. 5, this idler wheel mechanism 40 comprises two flexure strips 43, two L type gussets 42 and rollers 41, see also Fig. 6 and Fig. 7, this roller 41 comprises wheel shaft 413, cylinder 412 and elastoplast layer 411 from the inside to surface successively, be clearance fit between this wheel shaft 413 and this cylinder 412 wherein, this cylinder 412 can rotate relative to this wheel shaft 413, these L type gusset 42 1 ends are connected with this flexure strip 43 by bolt (not indicating), the other end has U type groove (indicate), and this U type groove is used to accommodate and supports this wheel shaft 413.
When this light guide plate and the assembling of reflector plate composite set, bolt 32 parts are screwed in the threaded hole 211 of transverse slat 21, a plurality of guide pin bushings 34 are respectively fixed in a plurality of unthreaded holes 212, be respectively fixed to an end of a plurality of guide pillars 31 in a plurality of unthreaded holes 112 of workbench 11 by screw thread or other fixed forms, be set on two guide pillars 31 rising spring 35, make the other end of a plurality of guide pillars 31 pass this guide pin bushing 34, and load onto stop collar 33 at this traversing through end, so just supporting mechanism 20 is assembled into workbench unit 10 by elevating mechanism 30.Again the free end of the flexure strip 43 of idler wheel mechanism 40 is respectively fixed to the appropriate location of riser 22,23 afterwards, makes roller 11 one-tenth certain inclination angles of 41 relative these workbenches and its contact portion be close to the side of workbench 11.
After assembling is finished, workbench unit 10 is in equilibrium state under the acting in conjunction of rising spring 35 and stop collar 33, when downward pressure affacts on the workbench 11, workbench unit 10 will descend with guide pillar 31 under the guiding of guide pin bushing 34 together, after pressure was cancelled, workbench unit 10 can move upward until returning to equilibrium state under the effect of rising spring 35 again.
See also Fig. 8 and Fig. 9, the use of light guide plate of the present invention and reflector plate composite set is described below step by step, the first step, be put into reflector plate 60 and light guide plate 50 on the workbench 11 from top to bottom in regular turn, the dual-side of reflector plate 60 is neat with positioning boss 113 tops respectively, the dual-side of light guide plate 50 is neat with locating piece 12 tops respectively, have the part (indicating) of light guide plate of protruding in 50 and workbench 11 at reflector plate 60 near roller 41 1 sides this moment, this outshot into strips and its width suitable with light guide plate 50 thickness; Second step, light guide plate 50 and workbench unit 10 are exerted pressure (figure does not show), in the decline process, roller 41 is folded to the strip outshot of reflector plate 60 light guide plate 50 sides and pushes applying, because 50 one-tenth certain inclination angles of roller 41 relative light guide plate, roller 41 keeps less surface of contact at any time with light guide plate 50, can guarantee enough applying extruding forces, again because the certain elasticity of outer elastoplast layer 411 tool of roller 41, so in extrusion process, can avoid damaging reflector plate 60 or light guide plate 50, in addition, this bolt 32 can play the effect that limits workbench unit 10 minimum down positions, and this minimum down position can be realized changing by the height of regulating bolt 32; In the 3rd step, turnover is fitted and is finished, and removes pressure, upsprings automatically together with light guide plate 50 in workbench unit 10, takes out the light guide plate 50 that is fitted with reflector plate 60.
Light guide plate of the present invention and reflector plate composite set are realized light guide plate 50 and the preceding accurate location of reflector plate 60 applyings by locating piece 12 and positioning boss 113 are set, when reducing, realizes workbench unit 10 turnover and the applying of reflector plate 60 by the squeezing action of roller 41, the present invention replaces the manual work mode of prior art with light guide plate and reflector plate composite set, reduced the time of contraposition and applying, made that light guide plate and the contraposition of reflector plate applying process are accurately convenient and applying efficient is higher.
This light guide plate and reflector plate composite set are not limited to said structure, and this stop collar 33 is replaceable to be other chocking constructions such as nut, latch; This bolt 32 can be replaced by a reference column that is fixed on the transverse slat 21; For idler wheel mechanism 40, carry out appropriate change by shape to its flexure strip 43, the one end is directly linked to each other with wheel shaft 413, can save L type gusset 42; For roller 41,, can save elastoplast layer 411 by making it have certain elasticity to suitably choosing of cylinder 412 materials; The positioning boss 113 on these workbench 11 surfaces can self be with the locating piece of boss to replace by one; These elevating mechanism 30 included guide pillar 31, guide pin bushing 34, rise spring 35 and chocking construction 33 numbers also can increase and decrease adjustment under the prerequisite that satisfies the device basic function.In addition, the situation for a side attaching reflector plate 60 that only needs light guide plate 50 can only adopt an idler wheel mechanism 40.
