Description

Technical Field

[0001] This utility model relates to the field of holographic light booth exposure technology, and in particular to a holographic light booth structure. Background Technology

[0002] Holographic grating exposure is a technique that uses laser interference to fabricate periodic microstructures on photosensitive materials. Its core lies in forming stable fringe patterns through the interference of two coherent beams, ultimately resulting in a high-precision grating structure through development and processing. The fabrication process relies on precise optical components, strict stability control, and meticulous adjustments. By optimizing the optical path symmetry, angle, and intensity balance step by step, high-precision, low-noise grating structures can be produced. However, these precision instruments are susceptible to external interference, such as airflow disturbances affecting components in the optical path and thus impacting the final result.

[0003] In addition, some components on the optical path require parameter adjustments during operation, which introduces certain uncertainties and interferes with the debugging results to some extent. For example, adjusting the operation time of the electronic timer will affect the air buoyancy of the optical platform, and some cables will affect the operability of the entire optical path, while the display screen will bring some stray light.

[0004] Currently, to address the aforementioned air flotation problem, operators typically erect baffles around the platform components to isolate the airflow. However, since some components on the optical path require parameter adjustments during operation, which introduces uncertainty, operators must adaptively adjust the baffles each time they make parameter adjustments. This process is cumbersome, and repeated baffle adjustments can also clutter the platform space, affecting the equipment wiring layout. Therefore, there is an urgent need to design a baffle to completely enclose the platform, thus solving the problem of the cumbersome operation of currently implementing airflow isolation by adjusting baffles. Utility Model Content

[0005] Therefore, the purpose of this utility model is to provide a holographic light booth structure, which aims to solve the problem that the current operation of airflow isolation by adjusting the partition is relatively cumbersome.

[0006] The present invention provides a holographic light box structure, including a support assembly, multiple sets of sliding partition assemblies slidably disposed at the side perimeter of the support assembly, and an upper sealing plate overlapping the top of the support assembly;

[0007] The support assembly includes at least six support beams arranged in a rectangular shape around the optical platform along the Y-axis, multiple first splicing beams overlapping the top and bottom of the six support beams along the X-axis, and multiple second splicing beams overlapping the top and bottom of the six support beams along the Z-axis.

[0008] The support beam, the first splicing beam, and the second splicing beam together form a rectangular cover that encloses the optical platform.

[0009] As described above, the initial support assembly can be constructed based on the optical platform using the support beam, the first splicing beam, and the third splicing beam to enclose the optical platform. Then, a sliding partition assembly is assembled around the support assembly, and a top sealing plate is erected, ultimately forming a rectangular flow shield erected on the surface of the optical platform. This achieves a closed optical path, preventing airflow disturbances from affecting the process results and improving the stability of the holographic grating during exposure operations. By adjusting the position of the sliding partition assembly, airflow disturbances can be isolated while facilitating the placement on the optical platform, solving the problem of the cumbersome operation when adjusting the partition to implement airflow isolation.

[0010] In addition, the holographic lighthouse structure proposed according to the embodiments of this utility model may also have the following additional technical features:

[0011] Furthermore, the bracket assembly also includes a plurality of right-angle pieces disposed at the bottom inside the first splicing beam, which are used to connect the bracket assembly to the optical platform. Two parallel grooves are provided on the first splicing beam for accommodating the sliding partition assembly.

[0012] Furthermore, the first splicing beam and the second splicing beam enclose a receiving space for accommodating the upper sealing plate, and a sealing plate limiting part for supporting the upper sealing plate extends out from the receiving space.

[0013] Furthermore, the sliding partition assembly includes a sliding frame that slides along the track of the slide groove, an acrylic plate embedded in the sliding frame, and a clamping buckle movably embedded on one side of the sliding frame for limiting the position of the acrylic plate.

[0014] Furthermore, the sliding frame includes a frame body, a push-pull handle fixedly disposed on one side of the frame body, and a sliding part disposed on the upper and lower sides of the frame body and embedded in the sliding groove.

[0015] Furthermore, the inner side of the frame is provided with a panel groove for accommodating the acrylic plate, and the clamp is embedded in the panel groove and located on the side of the frame away from the push-pull handle.

[0016] Furthermore, the clamp buckle includes a movable shaft, a positioning end extending along the axial direction of the movable shaft for connecting the frame, and a movable buckle extending outward along the circumferential direction of the movable shaft, wherein the movable buckle is driven by the movable shaft to flip toward the side closer to the acrylic plate.

[0027] Please see Figures 1 to 4The diagram shows the holographic lighthouse structure in this embodiment of the invention, including a support assembly 1, multiple sets of sliding partition assemblies 2 slidably disposed on the side perimeter of the support assembly 1, and an upper sealing plate 3 overlapping the top of the support assembly 1. The support assembly 1 includes at least six support beams 11 arranged in a rectangular shape around the optical platform along the Y-axis, multiple first splicing beams 12 overlapping the top and bottom of the six support beams 11 along the X-axis, and multiple second splicing beams 13 overlapping the top and bottom of the six support beams 11 along the Z-axis. The support beams 11, first splicing beams 12, and second splicing beams 13 together form a rectangular cover enclosing the optical platform. There are four first splicing beams 12, with each pair of first splicing beams 12 positioned at the upper and lower ends of three parallel support beams 11. Figure 2 As shown. The second splicing beam 13 has a total of 7 beams, which are respectively arranged between the support beam 11 and the first splicing beam 12. There are 2 beams at the bottom and 5 beams at the top. In some optional embodiments, the connection method between the support beam 11, the first splicing beam 12 and the second splicing beam 13 can be, but is not limited to, mortise and tenon splicing, welding, screwing, etc.

[0028] Furthermore, the support assembly 1 also includes multiple right-angle pieces 16 disposed at the bottom inside the first splicing beam 12, which are used to connect the support assembly 1 to the optical platform. The first splicing beam 12 has two parallel grooves 15 for accommodating the sliding partition assembly 2. The first splicing beam 12 and the second splicing beam 13 enclose a space for accommodating the upper sealing plate 3. A sealing plate limiting part 14 for supporting the upper sealing plate 3 extends from the accommodating space. The sliding partition assembly 2 includes a sliding frame that slides along the groove track 15, an acrylic plate 26 embedded in the sliding frame, and a clamping buckle 25 movably embedded on one side of the sliding frame for limiting the acrylic plate 26. The sliding frame includes a frame body 21 and a fixed A push-pull handle 22 is provided on one side of the frame 21, and a sliding part 23 is provided on the upper and lower sides of the frame 21 and embedded in the slide groove 15. The inner side of the frame 21 is provided with a panel groove 24 for accommodating the acrylic plate 26. The clamp buckle 25 is embedded in the panel groove 24 and located on the frame 21 away from the push-pull handle 22. The clamp buckle 25 includes a movable shaft 251, a positioning end 252 extending along the axial direction of the movable shaft 251 for connecting the frame 21, and a movable buckle 253 extending outward along the circumferential direction of the movable shaft 251. In some optional embodiments, the movable shaft 251 can also be a spring shaft or a damping shaft. The movable buckle 253 is driven by the movable shaft 251 to flip towards the side closer to the acrylic plate 26.

[0029] In practice, the operator can select the first splicing beam 12 and the second splicing beam 13 that match the outer diameter of the optical platform. A perimeter frame is erected on the top of the optical platform and fixed with right-angle pieces 16. Then, the operator can erect a support beam 11 on the top of the perimeter frame, and then erect the remaining first splicing beam 12 and the second splicing beam 13 on the top of the support beam 11 to complete the top frame construction. Finally, the bracket assembly 1 on the optical platform is set up. Then, the sliding partition assembly 2 is assembled on the perimeter of the bracket assembly 1, and the top sealing plate 3 is erected on the top, thus forming a rectangular flow shield erected on the surface of the optical platform. This achieves the sealing of the optical path, avoids airflow disturbance from affecting the process results, and improves the stability of the holographic grating in the exposure operation. To ensure the normal function of the optical platform, the bracket assembly 1 can be made of aluminum as the main material, and the acrylic plates 26 on the top sealing plate 3 and the sliding partition assembly 2 are both made of black acrylic.

[0030] Furthermore, regarding the use of the holographic lighthouse structure in this application, considering the irregularity of the component layout on the optical platform, movable sliding partition assemblies 2 are used around the support assembly 1. This is to effectively adapt to the irregularity of the component layout. Understandably, operators can open the corresponding sliding partition assembly 2 according to the component's position on the optical platform to complete the component layout operation at any point on the optical platform. Additionally, based on the work scenario, to improve the adaptability of the holographic lighthouse structure in this application, during component layout operations, operators can create wire grooves at any position on the acrylic plate 26 according to wiring needs to assist in wiring operations. At the same time, for some overused... If the acrylic sheet 26 or the top cover plate 3 has many openings or is incompatible with the wiring of other components, the operator can quickly replace it. Specifically, for the replacement of the top cover plate 3, the operator only needs to cut a piece of material that matches the size of the top cover plate 3 and cover it again in the accommodating space. For the acrylic sheet 26 in the frame 21, the operator only needs to flip the movable buckle 253 outward, take out the acrylic sheet 26 that is out of the limit of the movable buckle 253, insert the cut acrylic sheet 26 along the side that was taken out, and then loosen the movable buckle 253 to drive it to flip towards the side of the acrylic sheet 26 through the movable shaft 251, and finally abut against the edge of the acrylic sheet 26 to complete the assembly of the acrylic sheet 26. The installation method is simple and quick.

[0031] In summary, the initial support assembly 1 can be constructed based on the optical platform using the support beam 11, the first splicing beam 12, and the third splicing beam 13 to enclose the optical platform. Then, the sliding partition assembly 2 is assembled around the support assembly 1, and the top sealing plate 3 is erected, ultimately forming a rectangular flow shield erected on the surface of the optical platform. This achieves the sealing of the optical path, avoids airflow disturbance from affecting the process results, and improves the stability of the holographic grating in the exposure operation. By adjusting the position of the sliding partition assembly 2, the placement position on the optical platform is facilitated while isolating airflow disturbance, solving the problem of the cumbersome operation when adjusting the partition to implement airflow isolation.
