Technical Field

[0001] This utility model relates to the field of coating fixture technology, and in particular to a coating fixture for chromium-doped yttrium aluminum garnet crystals. Background Technology

[0002] Chromium-doped yttrium aluminum garnet (YAG) crystal, as an important laser gain medium and passive Q-switching material, is widely used in solid-state lasers due to its excellent physicochemical stability, high thermal conductivity, and wide absorption bandwidth. Chromium doping is a key method to modify crystal properties by introducing chromium ions, achieving a functional breakthrough from "passive Q-switching" to "laser gain" in YAG crystal. To improve its damage threshold, environmental stability, and optical performance, optical thin films are typically deposited on the crystal surface.

[0003] Crystals exist in plate, columnar, and irregular shapes due to varying application scenarios. Traditional clamps require complete replacement to match different sizes and shapes, which is time-consuming and labor-intensive. Frequent disassembly and assembly can also damage the vacuum chamber's sealing interface. Furthermore, their clamping parts cannot meet the clamping requirements of crystals of different shapes, resulting in certain limitations in the device. Utility Model Content

The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that excludes other embodiments.

[0023] Reference Figures 1 to 4 A coating fixture for chromium-doped yttrium aluminum garnet crystals includes a mounting base 1; wherein the mounting base 1 can be designed as an L-shaped structure and can be mounted on a device or platform using bolts or other fixing components to provide support points for the drive assembly 2 and the clamping assembly 3.

[0024] And, the drive assembly 2 includes a lead screw 24, an inner ring 26 threaded to the outer wall of the lead screw 24, and a moving block 25 fixedly connected to the end face of the inner ring 26. The outer wall of the lead screw 24 has threads with opposite directions on both sides. The moving block 25 and the inner ring 26 are fixedly connected and are designed as two sets, so that the yttrium aluminum garnet crystal can be clamped from the left and right sides to ensure the stability of the crystal clamping.

[0025] The clamping assembly 3 includes a positioning plate 31 disposed on the outside of the moving block 25 and a positioning part 32 fixedly connected to the end face of the positioning plate 31. The positioning plate 31 can be quickly slidably disassembled from the outer wall of the outer plate 29, and works with the positioning part 32 to clamp the crystal. The positioning part 32 with different shapes designed on the end face of different positioning plates 31 can meet the clamping requirements of crystals with corresponding shapes.

[0026] Specifically, the drive assembly 2 also includes a motor 21 disposed on the outside of the mounting base 1. A first mounting plate 22 is fixedly connected to the outer wall of the motor 21. The first mounting plate 22 has an L-shaped structure and is mounted on the end face of the mounting base 1. The motor 21 provides power input for the movement of the clamping assembly 3, and the L-shaped first mounting plate 22 allows the motor 21 to be mounted on the outer wall of the mounting base 1.

[0027] Reference Figure 1 , Figure 2 and Figure 3 A fixing block 23 is fixedly connected to the outer wall of the mounting base 1, and the end face of the lead screw 24 is rotatably connected to the outer wall of the fixing block 23. The fixing block 23 can be designed to be convex, with its end face fixedly connected to the mounting base 1 and its outer wall rotatably connected to the end of the lead screw 24, providing a support platform for the rotation of the lead screw 24.

[0028] Specifically, a transmission disc 27 is provided at the output end of the motor 21 and at the middle of the outer wall of the lead screw 24, and the projected contours of the two transmission discs 27 on the vertical plane coincide. The two transmission discs 27 are fixedly connected to the end faces of the motor 21 and the lead screw 24, respectively, and the rotation of the transmission discs 27 is achieved by driving the motor 21.

[0029] Furthermore, the end faces of the two transmission discs 27 are connected by a belt 28, and the end face of the belt 28 is integrally formed with an outer plate 29. The projections of the two transmission discs 27 in the vertical direction coincide, thereby ensuring that the belt 28 is installed vertically.

[0030] Reference Figure 3 and Figure 4 The clamping assembly 3 also includes a second mounting plate 34 integrally formed on the end face of the positioning plate 31, and an insertion plate 33 is fixedly connected to the outer wall of the positioning plate 31. The positioning plate 31 and the outer plate 29 are at the same height, so that after the positioning plate 31 and the outer plate 29 are inserted, the second mounting plate 34 covers the top wall of the outer plate 29, and the two are fixedly installed with bolts.

[0031] Specifically, the outer wall of the outer plate 29 is provided with a positioning groove 35 that matches the plug-in plate 33, and the second mounting plate 34 can be installed and removed from the end face of the outer plate 29. Multiple sets of plug-in plates 33 and positioning grooves 35 can be designed to ensure the stability of the connection between the positioning plate 31 and the outer plate 29.

[0032] Working principle: The mounting base 1 is fixed on the equipment or platform. The positioning part 32 that matches the shape of the yttrium aluminum garnet crystal to be clamped is selected according to the needs. The positioning plate 31 with the positioning part 32 is inserted into the positioning groove 35 on the outer wall of the outer plate 29 using the plug plate 33. At this time, the end face of the positioning plate 31 matches the end face of the outer plate 29. The second mounting plate 34 on the top of the positioning plate 31 covers the top of the outer plate 29. The positioning plate 31 and the outer plate 29 are connected by bolts to ensure the stability of the positioning part 32.

[0033] The motor 21 is started. The output end of the motor 21 and the middle of the outer wall of the lead screw 24 are fixedly connected to the transmission disk 27. The rotation of the transmission disk 27 at the end of the motor 21 is controlled by the motor 21. The belt 28 drives the two transmission disks 27 to rotate synchronously. The two ends of the lead screw 24 rotate on the outer wall of the fixed block 23, providing sufficient stability for the lead screw 24, thereby driving the lead screw 24 to rotate synchronously with the transmission disk 27.

[0034] Since the outer wall of the lead screw 24 has threads with opposite directions on both sides, the moving block 25 moves in opposite directions along the outer wall of the lead screw 24 during rotation. The movement of the moving block 25 can drive the clamping assembly 3 to clamp the yttrium aluminum garnet crystal from two directions. By using the drive assembly 2 and the clamping assembly 3 together, yttrium aluminum garnet crystals of different shapes and sizes can be clamped and positioned, improving the applicability of the device and the convenience of use.

[0035] It should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
