DETAILED DESCRIPTION

[0018] To better understand the present invention, the following examples further illustrate the present invention. However, the present invention is not limited to the following examples. In the following description, numerous specific details are provided to provide a more thorough understanding of the present invention. However, it is obvious to those skilled in the art that the present invention can be practiced without one or more of these details.

[0019] Example 1, see Figure 1 、 3 、4.

[0020] An auxiliary device for testing and adjusting the parallelism of a double-reflective dichroic plate comprises a support module 1, an ultraviolet irradiation lamp module 2, a laser emission module 3, a six-axis adjustment module 4, an observation module 5, and a color plate placement module 6. The support module 1 includes a rectangular horizontal profile frame 11, of which a base plate 12 is detachably fixed at one end along the length direction, and an observation module 5 is detachably fixedly connected at the other end vertically; a support platform 13 is fixedly connected to the side of the six-axis adjustment module 4 on the base plate 12 along the length direction of the profile frame 11, and a color plate placement module 6 is threadedly fixedly connected to one end of the support platform 13; a laser emission module 3 is threadedly fixedly connected to the other end of the support platform 13; a six-axis adjustment module 4 is detachably fixedly provided on one side of the support platform 13 on the base plate 12; an ultraviolet irradiation lamp module 2 is detachably fixedly provided on the other side of the support platform 13 on the base plate 12; the laser emission module 3 emits a group of parallel lasers with the line connecting the laser emission points horizontally relative to the color plate placement module, which are respectively irradiated on the dichroic plate reflecting red light and the dichroic plate reflecting green light in the dichroic plate module 7 to be tested, and the laser reflected by the dichroic plate is irradiated on the observation module 5.

[0021] Furthermore, a color plate bracket slot 61 is formed through the color plate placement module 6 , and the color plate bracket slot 61 is used to hold and place the color plate bracket 71 .

[0022] Furthermore, the laser emitting module 3 is provided with a transverse adjustment slot 31, which is threadedly fixedly connected to the support platform 13 via the transverse adjustment slot 31; the color plate placement module 6 is provided with a transverse adjustment slot 62, which is threadedly fixedly connected to the support platform via the transverse adjustment slot 62. The color plate placement module 6 and the laser emitting module 3 are connected by a removable threaded connection, allowing the color plate placement module 6 to be replaced with a color plate placement module 6 having a suitable color plate support slot 61 according to the different specifications of the dichroic plate module 7 to be tested. The first transverse adjustment slot 31 and the second transverse adjustment slot 62 can adjust the relative position between the laser emitting module 3 and the color plate placement module 6, so that a set of parallel laser light emitted by the laser emitting module 3, whose connecting line of laser emission points is horizontal with respect to the color plate placement module 6, respectively illuminates the dichroic plate reflecting red light and the dichroic plate reflecting green light.

[0023] Furthermore, the ultraviolet lamp module 2 includes a base 21, a lamp pole 22, a first limit block 23, a lamp pole rocker arm 24, a second limit block 25, and an ultraviolet lamp 26. One end of the lamp pole 22 is detachably fixedly connected to the bottom plate 12 via the integrally connected base 21. The other end of the lamp pole 21 is detachably fixedly connected to the first limit block 23, the lamp pole rocker arm 24, and the second limit block 25. The end of the lamp pole rocker arm 24 is fixedly connected to the ultraviolet lamp 26. In this manner, the ultraviolet lamp 26 of the ultraviolet lamp module 2 can be rotated relative to the lamp pole 22. During use, the ultraviolet lamp 26 can be quickly rotated and positioned above the dichroic plate module 7 to be irradiated through the cooperation of the lamp pole rocker arm 24 and the limit block. After irradiation is completed, the ultraviolet lamp 26 can be driven by the lamp pole rocker arm 24 to rotate relative to the lamp pole 22 away from above the dichroic plate module 7 where the UV glue has been cured, thereby not affecting the next process operation.

[0024] Furthermore, the observation module 5 includes an observation panel 51, an observation profile frame 52, and pixel grid paper 53. The observation profile frame 52 is detachably connected vertically to the horizontal profile frame 11. The observation panel 51 is threadedly connected to the side of the observation profile frame 52 near the color plate placement module 6. The pixel grid paper 53 is fixedly mounted on the surface of the observation panel 51. The pixel grid paper 53 can intuitively reflect the horizontal and vertical relative positions of the two laser detection points on the observation module 5 after the parallel laser beams emitted by the laser emission module 3 are reflected.

[0025] During use, first place the color plate holder 71 into the color plate holder slot 61, insert the red and green dichroic plates 72 and 73 into the color plate holder 71, and then activate the laser light source 32. The lasers emitted by the two laser light sources 32 are then reflected parallel to the two dichroic plates, resulting in two laser detection points on the observation module 5. If the two laser detection points are horizontal and the distance between them is consistent with the distance between the two laser emission points, the color plate parallelism meets the requirements. If the parallelism does not meet the requirements, use one of the dichroic plates as a reference, and use the six-axis adjustment module 4 to adjust the head against the other dichroic plate, adjusting the dichroic plate by small adjustments on the X, Y, and Z axes. The horizontal and vertical distances between the two laser detection points on the observation module 5, where the parallel lasers emitted by the laser emission module 3 are reflected by the two dichroic plates, are the same as the horizontal and vertical distances between the two laser emission points. After that, UV glue is applied to the two dichroic plates and the plate bracket 71 to secure them. Then, the UV lamp 26 can be quickly rotated by the cooperation of the lamp pole rocker arm 24 and the limit block to position it above the dichroic plate module 7 to be irradiated. The UV lamp 26 is turned on to irradiate the dichroic plate module 7. When the UV glue has cured, the UV lamp 26 can be driven by the lamp pole rocker arm 24 to rotate relative to the lamp pole away from the top of the dichroic plate module 7 where the UV glue has cured. The six-axis adjustment module 4 is withdrawn to adjust the abutment of the dichroic plates, and the dichroic plate module 7 that has been tested and adjusted can be removed.

[0026] The beneficial effects of this embodiment are as follows: by adopting a six-axis adjustment dichroic plate, the parallelism between the two dual-reflective dichroic plates can be quickly adjusted, which solves the problem of product inconsistency caused by the different parallelism of the color plates after assembly in the LCOS field, and realizes the rapid testing of the parallelism of the dual-reflective dichroic plates after assembly, thereby improving the requirements of production processes and production standards and reducing the generation of errors.

[0027] Example 2, see Figure 2 、 3 、4.

[0028] Furthermore, the observation module 5 includes an observation panel 51, an observation profile frame 52 and two through holes 54; the observation profile frame 52 is vertically and detachably connected to the horizontal profile frame 11, and the observation panel 51 is threadedly connected to the observation profile frame 52 on one side close to the color plate placement module 6; two horizontal fixed through holes 54 are opened on the observation panel 51 and are at an equal distance from the laser emission point.

[0029] When in use: first place the color plate bracket 71 into the color plate bracket slot 61, put the reflecting red light dichroic plate 72 and the reflecting green light dichroic plate 73 into the color plate bracket 71, light up the laser emission module 3, and at this time a group of parallel lasers emitted by the laser emission module 3 are irradiated on the two dichroic plates, and two laser detection points are presented on the observation module 5 after reflection; then use the six-axis adjustment module 4 to adjust the head against a dichroic plate, and make small adjustments by translation and rotation on the X, Y and Z axes, so that one of the parallel lasers emitted by the laser emission module 3 after reflection from the dichroic plate passes through one of the corresponding fixed through holes 54 opened on the observation panel in the observation module. Afterwards, UV glue is applied between the dichroic plate that is abutted and adjusted by the six-axis adjustment module 4 and the color plate bracket 71 and on the side away from the other dichroic plate to fix it, and then the UV lamp 26 can be positioned above the dichroic plate module to be irradiated by quickly rotating the lamp pole rocker arm 24 and the limit block. Turn on the UV lamp 26 to irradiate the dichroic plate that is abutted and adjusted by the six-axis adjustment module 4. When the UV glue has solidified, the UV lamp can be driven by the lamp pole rocker arm 24 to rotate relative to the lamp pole 22 to leave the top of the dichroic plate module 7 where the UV glue has solidified. Then, the six-axis adjustment module 4 is used to abut and adjust another dichroic plate and repeat the above-mentioned operation, thereby completing the testing and adjustment of the entire dichroic plate module 7.

[0030] The beneficial effects of this embodiment are as follows: by adopting a six-axis adjustment module to successively adjust the position between the two dichroic plates and the color plate bracket for curing, not only the rapid adjustment of the parallelism between the two dichroic plates is achieved, but also the position fixation between the two dichroic plates relative to the color plate bracket is achieved at the same time, thereby further improving the consistency and stability of the batch products produced, improving the requirements of the production process and production standards, and reducing the occurrence of errors.

[0031] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model and are not limiting. Other modifications or equivalent substitutions made to the technical solution of the utility model by ordinary technicians in this field should be included in the scope of the claims of the utility model as long as they do not depart from the spirit and scope of the technical solution of the utility model.

[0032] The above are merely preferred embodiments of the present invention and are not intended to limit the present invention. Those skilled in the art will readily appreciate that the present invention is susceptible to various modifications and variations. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of the present invention shall be included within the scope of protection of the present invention.
