Description

Technical Field

[0001] The utility model belongs to the technical field of coupling clamps, and in particular relates to a laser coupling clamp. Background Art

[0002] A laser is a device that can emit lasers. Lasers are when electrons in atoms absorb energy and transition from a low energy level to a high energy level, and then fall back from a high energy level to a low energy level. The energy released is released in the form of photons. The optical properties of the photons in the excited photon beam are highly consistent. Therefore, compared with ordinary light sources, lasers are more monochromatic, directional, and brighter.

[0003] For the laser diode and optical fiber metal sleeve used in the laser, when coupling these two components, an alignment fixture is needed to dock and fix the end face of the optical fiber metal sleeve with the LED tube cap of the laser diode, so that the light beam emitted from the laser diode can be coupled into the optical fiber end face in the optical fiber sleeve. During the coupling process, the fixation and docking of traditional clamps are relatively unstable, and the docking force is difficult to accurately control during the docking process, which can easily lead to problems such as squeeze damage of the laser diode and the optical fiber metal sleeve or gaps due to loose docking.

[0004] Therefore, a laser coupling fixture is proposed. Utility Model Content

[0008] Preferably, the screw threads in the first ball screw and the second ball screw have opposite rotation directions, and a through groove is formed at the top of the base near the outer sides of the first ball screw and the second ball screw.

[0009] Preferably, the laser diode docking platform and the optical fiber metal sleeve docking platform are slidably connected to the base via a slider and a slide groove.

[0024] It should be noted that, due to the relatively unstable fixation and docking of the laser diode and the optical fiber metal sleeve during the coupling process of the existing clamp, the docking force is difficult to accurately control during the docking process, which may easily lead to the problem that the laser diode and the optical fiber metal sleeve are squeezed and damaged or the docking is not tight and a gap occurs. In this embodiment, through the mutual cooperation of the positioning plate 8 and the positioning sleeve 10, the counterweight rod 16 can vertically penetrate the first positioning hole 9, the second positioning hole 14 and the third positioning hole 15 when the laser diode docking platform 6 and the optical fiber metal sleeve docking platform 7 are in a precise docking state, so as to achieve the docking of the positioning plate 8 and the positioning sleeve 10. The positioning plate 8 cannot continue to move under the limit, so as to achieve the precise docking of the laser diode docking platform 6 and the optical fiber metal sleeve docking platform 7, thereby avoiding the problem that the laser diode and the optical fiber metal sleeve are squeezed and damaged or the docking is not tight and a gap occurs.

[0025] Specifically, in this embodiment, this scheme mainly includes a positioning plug plate 8 and a positioning sleeve 10, the laser diode is installed inside the laser diode docking platform 6, and the optical fiber metal sleeve is installed inside the optical fiber metal sleeve docking platform 7. When coupling and docking are performed, the hand wheel 5 is rotated, and the hand wheel 5 drives the second ball screw 4 and the first ball screw 3 to rotate synchronously, the laser diode docking platform 6 on the first ball screw 3 and the optical fiber metal sleeve docking platform 7 on the second ball screw 4 move toward each other synchronously, the positioning plug plate 8 on the laser diode docking platform 6 and the positioning sleeve 10 on the optical fiber metal sleeve docking platform 7 move toward each other synchronously, the positioning plug plate 8 is inserted into the storage cavity 11 inside the positioning sleeve 10, the positioning plug plate 8 pushes the push block 13 to move, the push block 13 moves inside the storage cavity 11, and the push block 13 squeezes the first elastic Spring 12, the first spring 12 is compressed, the positioning plug plate 8 is gradually inserted into the positioning sleeve 10, the first positioning hole 9, the second positioning hole 14 and the third positioning hole 15 are on the same vertical line at an instant, at this time, after the counterweight rod 16 lacks the support of the push block 13, the counterweight rod 16 vertically penetrates through the first positioning hole 9, the second positioning hole 14 and the third positioning hole 15, to achieve the docking of the positioning plug plate 8 and the positioning sleeve 10, the positioning plug plate 8 cannot continue to move under the limit, and the laser diode docking station 6 and the optical fiber metal sleeve docking station 7 are precisely docked, and the rubber sealing ring 22 is squeezed when the laser diode docking station 6 and the optical fiber metal sleeve docking station 7 are docked, and the rubber sealing ring 22 is deformed and sealed under pressure to complete the docking of the laser diode docking station 6 and the optical fiber metal sleeve docking station 7.

[0026] The utility model provides a laser coupling fixture, such as Figure 1 and Figure 3 As shown, it includes an optical fiber metal sleeve docking station 7, a circuit switch sleeve 17 is fixedly connected to the outer wall of one side of the optical fiber metal sleeve docking station 7 near the lower position of the positioning sleeve 10 by bolts, an upper electrode sheet 18 is embedded on the inner wall of one side of the circuit switch sleeve 17, and a second spring 19 is arranged at the central position of the inner bottom of the circuit switch sleeve 17, a lower electrode sheet 20 is arranged on the top of the second spring 19, the upper electrode sheet 18 and the lower electrode sheet 20 are electrically connected, and the cross section of the upper electrode sheet 18 is a ring structure, a button 21 is arranged at the top center of the lower electrode sheet 20, the cross section of the button 21 is a T-shaped structure, and the bottom end of the button 21 passes through the upper electrode sheet 18.

[0027] Specifically, in the present embodiment, the present scheme mainly comprises a circuit switch sleeve 17. When the servo motor 2 is used to drive the first ball screw 3 and the second ball screw 4 to rotate through the output end on one side thereof, the laser diode docking platform 6 and the optical fiber metal sleeve docking platform 7 also move toward each other. After the laser diode docking platform 6 and the optical fiber metal sleeve docking platform 7 are docked, the counterweight rod 16 vertically penetrates through the first positioning hole 9, the second positioning hole 14 and the third positioning hole 15.

The second spring 19 is compressed by force, and the lower electrode sheet 20 and the upper electrode sheet 18 are separated. The servo motor 2 is powered off, thereby preventing the servo motor 2 from continuing to work and causing the laser diode docking platform 6 and the optical fiber metal sleeve docking platform 7 to be squeezed and damaged. By switching between the servo motor 2 and the hand wheel 5, the selection between electric and manual operation can be realized.
