[0002] Sapphire windows are optical components made of sapphire. Sapphire is a material with high hardness, high temperature resistance, corrosion resistance and good optical properties, so it can be used in optical, industrial and electronic fields. When used in various fields, sapphire windows are usually fixed to the workpiece by welding to make finished products for use in different fields. In special cases in different fields, two sapphire sheets need to be butt-welded to form specific optical components, such as large optical windows or prisms. Precise butt welding can ensure the continuity and stability of the optical path, reduce light scattering and loss, and improve optical performance.

[0015] Compared with the prior art, the present invention has the following beneficial effects: (1) Loosen the square plate to reset the limit spring in the buffer state, so that the U-shaped lock block moves toward the special-shaped fixture under the action of the positioning slide bar and the auxiliary spring, and the side of the special-shaped fixture enters into the opening of the U-shaped lock block, thereby fixing the special-shaped fixture at the current position and completing the installation operation of the special-shaped fixture. Since the strength of the limit spring is greater than that of the auxiliary spring, the contact strength and friction between the U-shaped lock block and the special-shaped fixture are enhanced, so that the equipment can replace special-shaped fixtures of different shapes without the help of tools. The operation is convenient and quick, which reduces the limitations of the equipment during use and improves the welding efficiency of the equipment; (2) When the two scraper blocks move relative to each other, when they move to the end, the driving wheel on them will contact the inclined surface of the driving inclined block, thereby providing an upward force to the driving wheel. Since the driving wheel is set on the auxiliary square plate, the auxiliary square plate will move at the upper limit of the auxiliary sliding column, so that the extrusion spring is in a buffering state, thereby driving the scraper block to move upward, preventing the residues dropped by the welding operation above the two scraper blocks from falling on the relative movement path of the two scraper blocks, causing the residues to be pushed to both sides and requiring the operator to actively clean them, thereby reducing the operator's work intensity. When the two scraper blocks reset and move, that is, move towards each other, the driving wheel moves down along the slope, causing the extrusion spring to reset and move, thereby driving the scraper block to reset and move to the surface of the welding table, and then cleaning a new round of residues, thereby reducing the limitations of the equipment during use, thereby improving the use effect of the equipment; (3) The two U-shaped square frames move toward each other and drive the guide square plate to move. Under the action of the locking slide column and the locking spring, the rotating disk is driven to move, so that the locking block on it moves. Since the sapphire window piece is fixed on the special-shaped fixture, and the special-shaped fixture is set on the locking block, the two sapphire window pieces can be docked together according to different placement forms through the movement of the two locking blocks. Then, the two docked sapphire window pieces are welded together by a welding laser to make a finished product. Through the continued movement of the U-shaped square frame, the guide square plate moves to the upper limit of the locking slide column, so that the locking spring is in a buffer state, thereby increasing the connection strength of the two sapphire window pieces, avoiding the displacement or dislocation of the two sapphire window pieces due to shaking during welding, and improving the welding accuracy and effect of the equipment; (4) The rotating gear rotates and meshes with the driving gear ring to rotate, so that the locking block on it rotates on the rotating disc through the rotating circular groove, and then the sapphire window piece on the locking block rotates, so that the two sapphire window pieces can be docked at different angles, reducing the limitations during use. At the same time, the docked sapphire window pieces can rotate together, which is convenient for the equipment to weld them, improves the welding effect and efficiency of the equipment, avoids dead angles in the welding process, reduces the limitations of the equipment during use, and further improves the use effect of the equipment; (5) The symmetrical scraping blocks on the top surface of the welding table continuously move toward and relative to each other. When the two scraping blocks move toward each other, the residues and debris generated during the welding process and dropped on the surface of the welding table can be cleaned up, and these impurities can be pushed into the through groove and dropped into the aggregate box, so as to avoid the residues generated by welding remaining on the welding table and affecting the subsequent welding operation of the equipment, thereby improving the welding effect of the equipment; (6) When the two sapphire window pieces are welded together and the locking block needs to be reset and moved and wait for the next welding operation, the telescopic cylinder is closed to reset the guide spring in the buffer state, thereby driving the special-shaped clamp on the locking block to reset and move, reducing energy consumption and improving the use effect of the equipment; it is worth mentioning that the two sides of the guide square plate are set on the guide slider, and the guide slider can move on the upper limit of the guide slide rail, so that the sapphire window pieces can be welded at different heights, reducing the limitations of the equipment during use and further improving the welding effect of the equipment; (7) When the sapphire window piece is moving, the two sides of the U-shaped square frame are moved within the upper limit of the guide square column through the sliding L plate, thereby limiting the movement of the sapphire window piece to prevent it from shaking or dislocation during movement. At the same time, the docking accuracy of the two sapphire window pieces is improved, the welding effect of the equipment is improved, and the stability of the sapphire window piece during movement is improved; at the same time, the sliding L plate will put the guide spring in a buffer state when moving, thereby causing damping to the movement of the sapphire window piece, preventing the telescopic cylinder from exerting too much force on the sapphire window piece, causing the two sapphire window pieces to collide with each other and be damaged, thereby improving the safety of the equipment during use.

The U-shaped locking block 59 moves toward the special-shaped clamp 5, and allows the side of the special-shaped clamp 5 to enter the opening of the U-shaped locking block 59, thereby fixing the special-shaped clamp 5 at the current position and completing the installation operation of the special-shaped clamp 5. Since the strength of the limit spring 49 is greater than the auxiliary spring 60, the contact strength and friction between the U-shaped locking block 59 and the special-shaped clamp 5 are enhanced, so that the equipment can replace special-shaped clamps 5 of different shapes without the aid of tools. The operation is convenient and quick, which reduces the limitations of the equipment during use and improves the welding efficiency of the equipment.

[0023] The present invention also provides a sapphire-to-sapphire clamping welding method, comprising the following steps: Step 1: fix the sapphire window piece required for welding on the special-shaped fixture 5 by moving the clamping assembly; Step 2: Use the execution locking parts to connect the two sapphire window pieces to form a specified shape; Step 3: Using the welding laser 3 to weld the spliced ​​sapphire window sheets; Step 4: Under the action of the welding arm 2, the welding laser 3 is made to weld at different angles.
