Detailed Description
The invention will be further elucidated and described with reference to the following embodiments and drawings in which:
referring to fig. 1, 2 and 3, the parallel optical coupling and laser fixing jig includes a main body 10 and a lens adsorption device 20, the lens adsorption device 20 is provided with a positioning groove 22 for accommodating a lens to be adsorbed, the positioning groove 22 is provided with a through hole 24, the diameter of the through hole 24 is smaller than that of the lens to be adsorbed, the main body 10 is provided with a through hole 12, the lens adsorption device 20 is fixed to the main body 10, the through hole 24 is communicated with one end of the through hole 12, and the other end of the through hole 12 is used for externally connecting an air extractor.
The lens to be adsorbed is placed in the positioning groove 22, the through hole 24 at the bottom of the positioning groove 22 is blocked, and then the air-extracting device is connected with the through hole 12 on the main body 10 and performs air extraction. By pumping out the air in the through hole 12, the air pressure in the through hole 12 is smaller than the external air pressure, so that the pressure difference is formed, and the to-be-adsorbed lens can be pushed in the direction with small air pressure, so that the purpose of stably fixing the to-be-adsorbed lens is achieved.
Further, the parallel optical coupling and laser fixing clamp further comprises an air pipe connector 30, and the air pipe connector 30 is connected with one end of the through hole 12 far away from the lens adsorption device 20. The air pipe connector 30 is connected with air extraction equipment, so that air leakage can be avoided when air is extracted, and the stability of air pressure difference is ensured, thereby ensuring the stable fixing effect of the lens. And the air pipe joint 30 is in threaded connection with the through hole 12, so that the air tightness of the connection is ensured, and the air pipe joint 30 is convenient to replace and disassemble.
The parallel optical coupling and laser fixing jig further comprises a fixing cover 40 fixed to the top end of the main body 10, wherein the fixing cover 40 is provided with a protrusion, and specifically, the protrusion is cylindrical. When the lens is welded, the parallel optical coupling and the laser fixing clamp can be fixed by the welding machine clamping hand, and the cylindrical protrusion of the fixing cover 40 can be well clamped and attached to the welding machine clamping hand, so that the fixing stability is improved, and the parallel optical coupling and the laser fixing clamp are prevented from shaking.
Further, the main body 10 is further provided with a light through groove 14, the bottom of the light through groove 14 is provided with a light outlet 16, the light outlet 16 is communicated with a through hole 24 of the lens adsorption device 20, the top of the light through groove 14 is provided with a light inlet 18, and the light outlet 16, the through hole 24 and the light inlet 18 are positioned on the same straight line. Before the lens is welded, a coupling test needs to be carried out on the parallel light passing through the lens to see whether the welding position of the lens meets the requirement.
The laser is placed at the light inlet of the through hole 24 and is in the same straight line with the through hole 24, light emitted after the laser is powered on passes through the lens and is converted into parallel light, the parallel light sequentially passes through the through hole 24, the light outlet 16 and the light through groove 14 and then reaches the light inlet 18, and at the moment, the light detector is placed at the light outlet of the light inlet 18 to receive the parallel light and convert the parallel light into an electric signal to be output. Whether the position of the lens is proper or not is judged through the strength of the output of the electrical signal of the optical detector, if the position is proper, the light passing through the lens is basically parallel light, and the parallel light can sequentially pass through the light outlet hole 16, the through hole 24 and the light inlet hole 18 which are in the same straight line, and if the position is not proper, the opposite is true.
At this time, although the light inlet 18 is communicated with the through hole 24 and communicated with the through hole 12, air leakage of the through hole 12 is caused when the through hole 12 is evacuated. Since the light inlet 18 is relatively small and the mass of the lens is relatively small, only the air extraction equipment needs to extract air with a certain power, and the air leakage of the through hole 12 does not affect the stable fixation of the lens.
In another embodiment, the light inlet hole 18 may be filled with a transparent material, such as transparent adhesive, i.e. T-shaped PC material, to make the through hole 12 in a sealed state.
The main body 10 is provided with a groove 11 for accommodating the optical detector, and the groove 11 is communicated with the light inlet 18. Further, after the optical detector is placed in the groove 11, the fixing cover 40 may cover the groove 11 to fix the optical detector.
Further, the lens adsorption device 20 is an integrating sphere. The integrating sphere can well collect the light emitted by the laser.
It should be finally noted that the above embodiments are only intended to illustrate the technical solutions of the present invention, and not to limit the scope of the present invention, and although the present invention has been described in detail with reference to the preferred embodiments, it should be understood by those skilled in the art that the technical solutions of the present invention can be modified or replaced with equivalents without departing from the spirit and scope of the technical solutions of the present invention.
