Abstract

A quick concentric fixing device for a semiconductor laser sealing cap comprises a positioning base and positioning holes formed by positioning blocks A and B. The positioning block B is fixed on thepressing sliding block. The positioning block A is provided with a positioning socket direction protrusion. As that position block A is provided with a protrusion in the direction of the position tubeseat, the direction of the tube is kept consistent, and the pressing sliding block drives the position block B to press the tube seat, so that the tube cap on the electrode is quickly concentric withthe tube seat. When the cap is tightened and fixed, As that pressure slide block in the concentric positioning device is press tightly by the pressing block of the cylinder sliding block, the positioning block B and the position block A are matched to press the pipe seat, The invention realizes the quick concentric of the tube cap and the tube seat, and accompanying with the quick welding of thetube cap and the tube cap, which ensures the stability of the position and is not easy to deflect, so that the failure rate is greatly reduced in the production and processing process, and the production efficiency is greatly increased in the cap sealing process.

Description

technical field [0001] The invention relates to a semiconductor laser sealing cap fast concentric fixing device, a fixing method and an application thereof, belonging to the technical field of laser accessory materials. Background technique [0002] In the 1970s, the success of room temperature continuous oscillation of semiconductor lasers and the realization of low-loss optical fibers opened the prelude to the era of optoelectronics. Semiconductor lasers are small in size and light in weight. efficient. Due to the advantages of long life, easy modulation and low price, it has been widely used in the fields of industry, medicine and military. This also promotes the industrialization of semiconductor lasers. Due to technical problems such as production processes, semiconductor lasers have three types of failures: early failure, accidental failure, and loss failure. In the industrial production of semiconductor lasers, it is inevitable to face the problem of how to eliminat...
