Embodiment Construction
[0033] The photodetector tail fiber coupling welding device and method according to the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.
[0034] The working principle of the present invention is: fix the detector tube shell with the detector tube shell fixing device 5, the tail pipe of the tube shell faces the pigtail fixing device 1, tighten the adjusting screw of the cooling block to make the moving part, and make the cooling block 16 and the detection The tube shell is in good contact. The pigtail is fixed by the pigtail fixing device 1, and the up and down adjustment screw rods and left and right adjustment screw rods of the three-dimensional adjustment frame 9 are adjusted so that the pigtails are located in the middle of the casing tail pipe, and the front and rear adjustment screw rods are slowly adjusted so that the pigtails are inserted into the casing tail pipe. Coupling alignment of th...

The invention provides a device and a method for pigtail coupling welding for a photoelectric detector. According to the device and the method provided by the invention, a detector pigtail fixing device is used for fixing pigtails, the pigtails are placed on the installation plate of the detector pigtail fixing device, and the pigtails are capable of carrying out up-and-down, left-and-right and front-and-back movements with the installation plate relative to the detector pigtail fixing device; a detector tube shell is further fixed by the detector pigtail fixing device, and the position of the detector tube shell is immovable; the coupling between the pigtails and a photosensitive diode in the detector tube shell is realized by adjusting the positions of the pigtails. A tube shell tail tube is heated and filled with a welding flux by charging an electrode connection rod, and further through a welding electrode which is electrically connected with the electrode connection rod. A photoelectric detector for finishing pigtail coupling welding through the method is high in alignment accuracy, good in welding effect, stable in coupling points, and capable of being widely applied to the field of pigtail coupling welding for photoelectric detectors.
Description
technical field [0001] The invention belongs to the technical field of optoelectronic device production technology, and in particular relates to a metallized optical fiber component coupling welding device and method, especially a photodetector tail fiber coupling welding device and method. Background technique [0002] The photodetector pigtail is a metallized optical fiber assembly. The photodetector pigtail is coupled and welded, that is, the metallized optical fiber assembly is aligned with the photodiode through the tail tube of the tube, and the gap between the optical fiber and the tail tube of the tube is filled with solder to ensure The coupling point is stable. [0003] Due to the limitations of the pigtail coupling welding process of the existing photodetector, the coupling point of the product is easily affected by environmental stress during long-term operation, and the product coupling shifts, resulting in product failure and failing to meet the needs of aerosp...
