[0020] See Figure 1-4 A high-energy laser generating device includes a worktable 8, a first laser 2, a second laser 3, a first convex lens 4, a second convex lens 5, and a third convex lens 12. The light emitted by the first laser 2 is parallel to the light emitted by the second laser. The first convex lens is located on the side of the first laser 2 that emits light, and the second convex lens is located on the side of the second laser 3 that emits light. The light emitted by the first laser 2 is collinear with the central axis of the first convex lens 4, and the light emitted by the second laser 3 is collinear with the central axis of the second convex lens 5. The third convex lens 12 is disposed on the worktable 8 on the side of the assembly formed by the first convex lens 4 and the second convex lens 5 that faces away from the first laser 2. The central axis of the third convex lens 12 is located between the first convex lens 4 and the second convex lens 5. On the perpendicular bisector L of the connection segment, the perpendicular bisector L is parallel to the light emitted by the first laser 2. The worktable 8 is provided with a first driving mechanism that drives the first convex lens 4 and the second convex lens 5 to move linearly, and a second driving mechanism that drives the third convex lens 12 to move linearly. The path of the first driving mechanism that drives the first convex lens 4 and the second convex lens 5 to move is parallel to the light emitted by the first laser 2, and the path of the second driving mechanism that drives the third convex lens 12 to move is parallel to the light emitted by the first laser 2. The parameters of the first convex lens and the second convex lens are the same. The distance from any point on the outer edge of the third convex lens 12 to the central axis of the third convex lens 12 is greater than the distance from the central axis of the first convex lens to the central axis of the third convex lens 12.
[0021] In use, the distance between the first convex lens 4 and the second convex lens 5 relative to the first laser 2 and the second laser 3 is first adjusted by the first driving mechanism as needed. Then, the third convex lens 12 is adjusted to the focal point of the first convex lens 4 by the second driving mechanism. Since the parameters of the first convex lens and the second convex lens are the same, that is, the focal lengths of the first convex lens and the second convex lens are also the same, the first convex lens 4 focuses the light emitted by the first laser 2 onto the third convex lens 12. At the same time, the second convex lens 5 focuses the light emitted by the second laser 3 onto the third convex lens 12. Then, the third convex lens 12 focuses the light in this way to obtain a laser light with higher intensity.
[0022] As a preferred embodiment, a placement plate 6 is installed on the lower side of both the first laser 2 and the second laser 3. A fixing frame 601 is fixedly connected to the upper side of the placement plate 6. A limiting rod 603 is spirally connected to the fixing frame 601. A limiting plate 602 is fixedly connected to one side of the placement plate 6.
[0023] The limiting plate 602 can limit the position of the first laser 2 and the second laser 3 to be installed on the placement plate 6, so that the first laser 2 and the second laser 3 are in contact with the limiting plate 602. Then, the limiting rod 603 is rotated to connect with the first laser 2 and the second laser 3, thereby fixing the position of the first laser 2 and the second laser 3 on the placement plate 6.
[0024] In a preferred embodiment, the first driving mechanism includes a sliding groove 7, a threaded rod 701, and a sliding block 703. The worktable 8 has symmetrical sliding grooves 7. The threaded rod 701 is rotatably connected inside the sliding groove 7. The sliding block 703 is helically connected to the threaded rod 701. The first convex lens 4 and the second convex lens 5 are both mounted on the sliding block 703. The threaded rod is parallel to the light emitted by the first laser 2.
[0025] With this setup, when the positions of the first convex lens 4 and the second convex lens 5 need to be adjusted, rotating the threaded rod 701 inside the sliding groove 7 allows the sliding block 703 to move within the sliding groove 7, thereby changing the positions of the first convex lens 4 and the second convex lens 5. This ensures that the first convex lens 4 and the second convex lens 5 are either closer to the first laser 2 and the second laser 3, or closer to the third convex lens 12. The specific positions are adjusted according to the experimental procedures and requirements.
[0026] As a preferred embodiment, a helical rod 702 is rotatably connected to the side of the worktable 8. A bevel gear 704 is fixedly connected to both the helical rod 702 and the two threaded rods 701. The bevel gear 704 on the helical rod meshes with the bevel gear 704 on the two threaded rods 701.
[0027] When the spiral rod 702 is rotated, it will drive the bevel gear 704 on the spiral rod 702 to rotate. When the bevel gear 704 on the spiral rod 702 rotates, it will drive the bevel gears 704 on the two threaded rods 701 and the threaded rods 701 to rotate simultaneously. Thus, by rotating one spiral rod 702, the position of the first convex lens 4 and the second convex lens 5 can be changed at the same time, and the position between the first convex lens 4 and the second convex lens 5 is always relatively fixed.
[0028] In a preferred embodiment, the second drive mechanism includes a threaded main rod 1011, an outer plate 10, and an auxiliary rod 1012. The outer plate 10 is screwed to one side of the worktable 8 via the threaded main rod 1011. The third convex lens 12 is mounted on the outer plate 10. Symmetrical auxiliary rods 1012 are fixedly connected to one side of the worktable 8. The auxiliary rods 1012 are slidably connected to the outer plate 10. Both the auxiliary rods 1012 and the threaded main rod 1011 are parallel to the light emitted by the first laser 2.
[0029] With this configuration, rotating the threaded main rod 1011 allows the outer plate 10 to slide on the auxiliary rod 1012, enabling the third convex lens 12 on the outer plate 10 to move away from or closer to the first convex lens 4 and the second convex lens 5, so that the third convex lens 12 can be adjusted to the focal point of the second convex lens 5 before use.
[0030] As a preferred embodiment, a servo motor 9 is disposed below the worktable 8, the output shaft of the servo motor 9 is fixedly connected to the lower surface of the worktable, and the output shaft of the servo motor 9 is perpendicular to the upper surface of the worktable.
[0031] The servo motor 9 is controlled by an external PLC, which allows the orientation of the entire device to be adjusted.
[0032] As a preferred embodiment, a limiting frame 11 is installed below the worktable 8. The limiting frame 11 is fixedly connected to the base 1. An arc-shaped groove 111 is provided on the limiting frame 11. A sliding rod 112 is rotatably connected to the lower side of the worktable 8. The sliding rod 112 is slidably connected to the arc-shaped groove 111.
[0033] When the servo motor 9 drives the optical device on the worktable 8 to deflect at an angle, the worktable 8 will rotate on the base 1. When the worktable 8 rotates, it will drive the sliding rod 112 to slide inside the arc groove 111. The arc groove 111 plays a certain limiting role on the sliding position and angle of the sliding rod 112, thereby improving the stability of the worktable 8 when it rotates and limiting the rotation angle of the worktable 8.
