[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.
[0020] Reference Figure 1-3An auxiliary grating exposure device includes a base plate 1, a cover plate 5 hinged to the outer wall of the base plate 1, a limit frame 14 fixedly connected to the side of the cover plate 5 away from the base plate 1, an adjusting bolt 10 rotatably connected to the outer wall of the cover plate 5, an aperture stop 11 threadedly connected to the outer wall of the adjusting bolt 10, a rotating ring 12 rotatably connected to the side of the aperture stop 11 away from the cover plate 5, and a metal sheet 13 provided on the outer wall of the rotating ring 12. By hinged to the base plate 1 and the cover plate 5, the cover plate 5 and the base plate 1 can rotate, thereby facilitating the installation of the sample. The limit frame 14 is provided on the outer wall of the cover plate 5. The frame 14 limits the aperture stop 11, allowing the aperture stop 11 to move within the limiting frame 14. The adjusting bolt 10 is threadedly connected to the aperture stop 11, allowing the adjusting bolt 10 to adjust the position of the aperture stop 11, thereby enabling the metal sheet 13 to better fit with the sample. By rotating the rotating ring 12, the multiple metal sheets 13 can be adjusted, changing the light-transmitting aperture formed by the multiple metal sheets 13. Thus, the light-transmitting aperture formed by the metal sheets 13 can be adjusted according to the different sizes of the sample, allowing the sample to be better exposed.
[0021] Reference Figure 1-3 Several metal sheets 13 are provided, and each metal sheet 13 is connected to a rotating ring 12. The metal sheets 13 are arranged in a circular array, and one end of each metal sheet 13 is slidably connected to the rotating ring 12. When the rotating ring 12 rotates, it can drive the metal sheets 13 to adjust their positions. Thus, the light-transmitting aperture formed by the metal sheets 13 can be effectively adjusted by rotating the rotating ring 12.
[0022] Reference Figure 1 A fixing block 2 is fixedly connected to the outer side wall of the base plate 1. A first fixing bolt 3 is rotatably connected to the inner side wall of the fixing block 2. A connecting block 4 is sleeved on the outer side wall of the first fixing bolt 3. A nut 15 is threadedly connected to the outer side wall of the first fixing bolt 3. By aligning the connecting block 4 installed on the outer side wall of the cover plate 5 with the fixing block 2 installed on the outer side wall of the base plate 1, and passing the first fixing bolt 3 between the fixing block 2 and the connecting block 4, the cover plate 5 can rotate around the first fixing bolt 3. By installing nuts 15 at both ends of the first fixing bolt 3, the fixing block 2 and the connecting block 4 can be limited to prevent misalignment between the base plate 1 and the cover plate 5.
[0023] Reference Figure 1The end of the connecting block 4 away from the first fixing bolt 3 is fixedly connected to the cover plate 5. Nuts 15 are located on both sides of the connecting block 4. The connecting block 4 is located on both sides of the fixing block 2. By making the fixing block 2 and the connecting block 4 in a straight line, through holes are opened on the outer walls of the fixing block 2 and the connecting block 4. The through holes opened inside the fixing block 2 and the connecting block 4 are adapted to the outer walls of the first fixing bolt 3, so that the first fixing bolt 3 can effectively install the fixing block 2 and the connecting block 4, thereby allowing the base plate 1 and the cover plate 5 to rotate.
[0024] Reference Figure 2 and Figure 4 The outer side wall of the base plate 1 is provided with a sliding groove 6, and the inner side wall of the base plate 1 is slidably connected to a slider 7. The top of the slider 7 is threadedly connected to a second fixing bolt 8, and the outer side wall of the second fixing bolt 8 is rotatably connected to a locking block 9. By installing the slider 7 in the sliding groove 6 on the outer side wall of the base plate 1, and the outer side wall of the slider 7 is threadedly connected to the second fixing bolt 8, the second fixing bolt 8 can drive the locking block 9 to limit the sample and prevent the sample from shifting during exposure.
[0025] Reference Figure 2 and Figure 4 The outer wall of the slider 7 is adapted to the inner wall of the slide groove 6. There are four slide grooves 6 distributed around the base plate 1. By adapting the outer wall of the slider 7 to the inner wall of the slide groove 6, the slider 7 can slide inside the slide groove 6. Thus, the slider 7, the second fixing bolt 8 and the locking block 9 set around the base plate 1 can limit and fix the sample, so that the sample can be installed at the top center of the base plate 1, and the sample can be adapted to the through hole, so as to better expose the sample.
[0026] Working principle: By placing the sample on the outer wall of the base plate 1, the slider 7 slides inside the slide groove 6. The slide groove 6 drives the four second fixing bolts 8 and locking blocks 9 to limit the sample around its perimeter. Rotating the second fixing bolts 8 clamps and fixes the locking blocks 9 and slider 7 to the base plate 1, thus limiting and fixing the sample and preventing it from moving. By rotating the adjusting bolt 10, the position of the aperture stop 11 inside the limiting frame 14 is adjusted so that the aperture stop 11 can effectively fit with the sample. By rotating the cover plate 5, the base plate 1 and the cover plate 5 clamp the sample inside, so that the metal sheet 13 can effectively fit with the sample. By rotating the rotating ring 12, the rotating ring 12 drives the multiple metal sheets 13 to move, thereby adjusting the light-transmitting aperture formed by the multiple metal sheets 13 to match the light-transmitting aperture with the sample, thus better exposing the sample.
[0027] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
