specific Embodiment approach 2

[0070] Embodiment 2: This embodiment differs from Embodiment 1 in that: the front end of the total reflection light cone 1 is made of an aluminum reflector or a reflector coated with a reflective film. Others are the same as the first embodiment.

[0071] According to different laser beam types in this specific embodiment, the total reflection light cone 1 can be classified into aluminum reflectors or reflective film-coated reflectors.

specific Embodiment approach 3

[0072] Specific implementation mode three: combination Figure 8 and 9 This embodiment is specifically described. The difference between this embodiment and the first or second embodiment is that a vertical camera imaging calibration device 14 is arranged above the second total reflection mask 2-2, and a horizontal camera imaging calibration device is arranged in the horizontal direction. device 15. Others are the same as those in Embodiment 1 or 2.

[0073] In this specific embodiment, the vertical camera imaging calibration device 14 and the horizontal camera imaging calibration device 15 conduct observations in both vertical and horizontal directions, and the purpose of the observations is to allow the parts to be welded to reach a predetermined position.

[0074] The focused small halo of this specific embodiment is fixed because its irradiation area is fixed, so by moving the first part to be welded to match the position of the small halo, and then the distance of the a...

Abstract

The invention discloses a carbon dioxide welding machine and a welding method thereof and belongs to the technical field of optical fiber welding and laser welding, solving the problems that conventional welding devices have short service life and are uneven in light irradiation during welding to cause uneven heating of optical materials and difficulty in controlling size of pads accurately. The carbon dioxide welding machine comprises a carbon dioxide laser, three 45-degree reflectors, a light chopper, a laser focusing device, two clamp devices, a three-dimensional electric translation stageand an operating platform. The method includes regulating the joint of to-be-welded parts to the focus of a second total-reflection mask, allowing an emitted laser beam to reflect to the light chopperand then reflect to the laser focusing device to obtain an external laser beam, allowing the external laser beam to directly irradiate to the front end of a total-reflection light cone, while reflecting a scattering laser beam to the inner ring surface of a first total-reflection mask to converge the scattering laser beam into a parallel laser beam, and then converging the parallel laser beam tothe focus of the second total-reflection mask.

Description

technical field [0001] The invention belongs to the technical field of optical fiber welding and laser welding. Background technique [0002] With the development of high-power solid-state lasers and fiber lasers, and the continuous improvement of the quality of high-power semiconductor laser beams, the demand for high-power energy-transmitting optical fibers will increase. The following problems need to be solved in the direct application of high-power energy-transmitting bare optical fiber: [0003] 1. The core diameter of the optical fiber is very thin, and the high-power laser is focused into the optical fiber through the lens. The power density of the end face of the optical fiber is extremely high, and the optical fiber is easily damaged. Therefore, the end face of the optical fiber is required to be free from any damage and pollution, which is extremely demanding; [0004] 2. The area of ​​the end face of the optical fiber is small, and it is not easy to carry out co...
