The third bracket is perpendicular to the plane that the first bracket and the second bracket defines and is connected with the second bracket through the adjusting screw; the third bracket is connected with a pole whose other end has the ball shaft; the ball shaft is located in the groove that is pre-arranged in the adjusting block and the fixing block. The whole fixing procedure of the optic debugging device can be done by only one person, thus the producing efficiency is greatly improved.
Description
The utility model relates to a kind of optics debugging apparatus of reflecting liquid crystal projector.
The imaging of reflecting liquid crystal projector, need to adjust the focal length of green, red, blue three dichroic liquid crystal chips, and make three look imagings realize overlapping, when adjusting focal length, the liquid crystal chip frame is moved along the x direction of principal axis, along x, y, the rotation of z axle, overlap simultaneously, need to adjust the liquid crystal chip frame and move along y, z axle for making three look imagings.After finishing above adjustment, need to use UV photosensitive glue that the liquid crystal chip frame is fixed on the chip stand, in the past in this whole debug process, be to hold chip carrier by hand by the people to adjust to the optimum position, fix by another one human UV photosensitive glue, it is high to grasp difficulty with staff when three look imagings are overlapped, and has dither image just can not overlap slightly.The UV photosensitive adhesive curing needed for 8 to 10 seconds, and during this period, very difficult assurance is held the hand of chip carrier and do not stirred a finger; On the other hand, owing to must there be two people to operate inefficiency simultaneously.
The purpose of this utility model is to provide a kind of optics debugging apparatus of reflecting liquid crystal projector, making the liquid crystal chip frame can press close to chip carrier is convenient to light-sensitive emulsion and fixes, can make chip carrier in setting range, reach and move again along x, y, the rotation of z axle, and adjust and fix with light-sensitive emulsion after three look imagings overlap, overall process only needs one man operation.
For achieving the above object, solution of the present utility model is: a kind of optics debugging apparatus of reflecting liquid crystal projector, it is characterized in that: comprise support, stage clip, ball journal, fixed block, adjustment piece, gib screw, set screw etc., first support is vertically connected at second support by set screw, the 3rd support is connected by set screw with second support on the direction of determining the plane perpendicular to first support and second support, the 3rd support connecting link, the other end of bar has ball journal, and ball journal places to be adjusted in the groove that piece and fixed block preset;
The junction of first support and second support is provided with gib screw, and the junction of second support and the 3rd support is provided with gib screw, and the junction of the 3rd support and ball journal bar is provided with gib screw;
Be provided with stage clip between first support and second support, be provided with stage clip between second support and the 3rd support, be provided with stage clip between the 3rd support and the bar;
This groove that is used to place ball journal cooperates and constitutes by adjusting hemisphere pit on the piece and the hemisphere pit on the fixed block, adjusts piece and fixed block and is connected and fixed by set screw;
The top of this ball journal processes a plane.
Owing to adopted above-mentioned solution, the operator only needs respectively the chip carrier of green, red, blue three debugging apparatus to be done rotation adjustment, make the coincidence of adjusting three look imagings after its imaging by set screw, inject light-sensitive emulsion at last and use ultraviolet light polymerization, this overall process only needs a people to finish, and has improved production efficiency.
The utility model will be further described below in conjunction with description of drawings and specific embodiment.
Fig. 1 is a front schematic view of the present utility model.
Fig. 2 is a schematic top plan view of the present utility model.
Fig. 3 is the partial schematic sectional view of second, third support junction of the utility model.
Fig. 4 is the synoptic diagram that the utility model is connected with chip carrier.
See also Fig. 1, Fig. 2, first support 5 is connected on second support 7 by set screw 1, between first support 5 and second support 7 first stage clip 6 is arranged, second support, 7 other ends are connected on the 3rd support 8 by set screw 9 equally, be provided with second stage clip 10 between second support 7 and the 3rd support 8, the 3rd support 8 other ends are by set screw 11 connecting links 22, the other end of bar 22 is ball journals 4, it is flexible and easy to process for ball journal 4 is rotated, ball journal 4 tops mill out a plane 23, ball journal 4 put into adjust the default groove that cooperates with ball journal 4 of piece 2 and fixed block 3, fixed block 3 passes through set screw 16 with adjustment piece 2,17 are connected and fixed, and adjust between piece 2 and the 3rd support 8 and are provided with the 3rd stage clip 12.
Fig. 3 is the partial schematic sectional view of second, third support junction, after adjust the position of set screw 11, gib screw 15 can be tightened, guarantee that the position that set screw 11 is adjusted does not change, first support 5 and 7 vertical connections of second support, except set screw 1, also be provided with gib screw 13, its coupling part structure is with shown in Figure 3 identical; The 3rd support 8 is connected with second support 7 at the in-plane of determining perpendicular to first, second support, except set screw 9, also be provided with gib screw 14, its coupling part sectional structure is also with shown in Figure 3 identical, and the effect of gib screw 15 is identical among the effect of gib screw 13,14 and Fig. 3.
The part 161,171 that is connected and fixed set screw 16, the 17 back-out extensions of adjusting piece 2 and fixed block 3 can be used to install and fix chip carrier.Adjust the degree of tightness amount of ball journal 4 by set screw 16,17, then adjust piece 2, fixed block 3 and on the chip carrier that installs and fixes rotate in the positive and negative 10 ° of scopes of three-dimensional around ball journal 4, set screw 1,9,11 can spinning in and out 4 millimeters: respectively with stage clip 6,10,12 compressions, rely on the elastic force of spring to retreat during back-out during the set screw precession.Because first, second, third support is vertically to connect mutually,, that is to say to adjust to be fixed on the amount of movement of chip carrier on x, y, z axle of adjusting on piece 2 and the fixed block 3 by adjusting set screw 1,9,11.
