Traditional cooling methods include natural cooling, air cooling and the use of cooling medium, etc. However, with the increasing demand for quality of optical elements, the cooling speed and uniformity are also increasing. In order to meet this demand, the cooling method using liquid as cooling medium is gradually widely used.
[0003] The existing optical element cooling method usually immerses the optical element in a container filled with cooling liquid when using liquid as cooling medium, and achieves rapid cooling by heat exchange between the liquid and the surface of the optical element. Although this method can achieve the basic cooling purpose, it is easy to cause poor contact due to the floating or sinking of the optical element in actual operation, which further affects the uniformity and efficiency of cooling. In addition, the direct contact of the optical element with the wall or bottom of the cooling pool may also cause local overcooling, resulting in cracks or other defects on the surface of the optical element, which not only reduces the yield, but also may affect the quality of the final product.

DETAILED DESCRIPTION
[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0017] Please see Figs. 1-3This utility model provides a technical solution: a rapid cooling device for optical component processing, comprising a cooling pool body 1, with an inlet and an outlet on both sides of the cooling pool body 1, and guide posts 2 at each of the four corners inside the cooling pool body 1. The upper ends of the guide posts 2 extend to the outside of the cooling pool body 1, and the bottom ends of the guide posts 2 are connected to a bottom partition 3 located at the bottom of the cooling pool body 1. The four corners of the bottom partition 3 are fixedly fitted onto the outside of the guide posts 2, and the top ends of the guide posts 2 are connected to a lower pressure plate 5 located outside the cooling pool body 1. The four corners of the lower pressure plate 5 are movably fitted onto the outside of the guide posts 2, and side partitions 4 can be detachably installed on both sides of the bottom of the lower pressure plate 5. The top of the guide column 2 is connected to a horizontally distributed crossbar 6 via a bracket. Adjusting studs 7 are threaded onto the crossbar 6 to adjust the vertical position of the lower pressure plate 5 inside the cooling pool body 1. A fixed base 12 is welded to the bottom of the cooling pool body 1, and extension plates 13 are movably mounted on both sides of the fixed base 12. This structure of the guide column 2 not only supports the bottom partition 3 located at the bottom of the cooling pool body 1, providing a stable platform for placing the optical components to be cooled and preventing localized overcooling caused by direct contact with the bottom of the cooling pool, but also connects the guide column 2 to the lower pressure plate 5. Adjusting the crossbar 6 via adjusting studs 7 allows for adjustment of the vertical position of the lower pressure plate 5 inside the cooling pool body 1. The stud 7 allows for precise adjustment of the vertical position of the lower pressure plate 5, enabling it to stably fix the side partition 4 in the appropriate position as needed. This prevents the optical components from floating or tilting, ensuring their stability during cooling and preventing direct contact with the cooling tank wall. This effectively avoids poor contact caused by floating or sinking, improving cooling efficiency and uniformity. Simultaneously, the fixed base 12 and its two side extension plates 13 provide a stable foundation, allowing the device to adapt to different working environments or requirements. This solves the problem in existing technologies where direct contact between the optical components and the cooling container wall leads to localized overcooling, surface cracks, or other defects. This improves yield and product quality. A pressing member 8 is welded to the bottom of the adjusting stud 7, and a pressing interface matching the structure of the pressing member 8 is welded to the center of the top of the lower pressure plate 5. A spring member 9 is sleeved on the upper end of the guide post 2, and the upper and lower ends of the spring member 9 are respectively connected to the bottom of the top bracket of the guide post 2 and the top of the lower pressure plate 5. With this structure, when the adjusting stud 7 rotates to adjust the pressing member 8 and presses down against the pressing interface on the top of the lower pressure plate 5, the lower pressure plate 5 can move vertically downwards under pressure. The spring member 9 provides a counter-force, helping to stabilize the position of the lower pressure plate 5 and ensuring that the optical components maintain their optimal position throughout the cooling process. T-shaped brackets 10 are symmetrically welded and fixed on both sides of the bottom of the lower pressure plate 5, and a T-shaped locking block 11 that matches the structure of the T-shaped bracket 10 is welded and fixed on the top of the side partition 4. With this structure, the side partition 4 can ensure a tight and stable connection between the side partition 4 and the lower pressure plate 5 by inserting the T-shaped locking block 11 into the T-shaped bracket 10.This design avoids displacement or loosening caused by external forces, ensuring that the side partition 4 effectively prevents optical components from floating or tilting during cooling. It also facilitates disassembly and makes use more convenient. Both sides of the expansion plate 13 are fixed with positioning shafts 15 via connectors, and positioning sleeves 14 are provided at the four corners of the fixed base 12. The rear end of the positioning shaft 15 is movably inserted into the positioning sleeve 14, which is connected to a locking screw via a threaded structure. This structure allows the expansion plate 13 to be flexibly adjusted on both sides of the fixed base 12 to adapt to different working environments. The movable connection between the positioning shaft 15 and the positioning sleeve 14 ensures that the expansion plate 13 can move and be positioned smoothly. The threaded screws on the positioning sleeve 14 can securely lock the expansion plate 13 after it has been adjusted to the appropriate position, preventing any possible displacement or loosening. Both the bottom partition plate 3 and the lower pressure plate 5 are rectangular plates with evenly distributed permeation holes. This structure allows coolant to flow freely through the bottom partition plate 3 and the lower pressure plate 5, ensuring that the coolant can fully contact the surface of the optical element to be cooled, thereby achieving more efficient heat exchange. The permeation holes on the lower pressure plate 5 ensure that the coolant can still flow smoothly when pressure is applied to fix the optical element, without obstructing the coolant's circulation path due to the presence of the lower pressure plate 5, thus guaranteeing temperature uniformity during the cooling process.
[0018] Working principle: When using this optical element processing rapid cooling device, firstly, place the optical element to be cooled on the bottom partition 3 through the opening of the cooling pool body 1, ensuring that the optical element is stable and centered. Next, insert the side partition 4 into the T-shaped bracket 10 using the T-shaped clip 11, so as to install it symmetrically at the bottom of the lower pressure plate 5. Then, rotate the adjusting stud 7 on the crossbar 6 to move the bottom pressing member 8 downward and contact the pressing interface at the top center of the lower pressure plate 5, gradually applying pressure to make the lower pressure plate 5 descend vertically along the guide post 2 to a suitable height. At this time, the spring member 9 will provide a certain reverse elastic force to stabilize the lower pressure plate 5. Continue adjusting the position of the adjusting stud 7 until the lower pressure plate 5 and the side partition 4 completely fix the optical element. Next, inject coolant through the inlet and outlet ports on both sides of the cooling pool body 1 to start the cooling process. The coolant will flow freely through the permeation holes on the bottom partition 3 and the lower pressure plate 5 to ensure that the coolant can fully contact the surface of the optical element and achieve efficient heat exchange. During the cooling process, the position of the expansion plate 13 can be finely adjusted according to actual needs. It is fixed by the movable connection between the positioning shaft 15 and the positioning sleeve 14 and the clamping screws on the positioning sleeve 14 to adapt to different working environment requirements and thus complete a series of tasks.
[0019] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
