The design thought can improve the safety and reliability of product screening while reducing the cost and enhancing the efficiency, and provides certain assistance for the mass production assembly line mode.
The appearance of the single-channel ASE light source assembly fixture 1 is designed in an 8 shape. The method has the functions of assembling and fixing ASE light source component products and enabling the ASE light source component products to be used as the minimum module of the whole tool assembly to circulate among tools.

1. the single-path ASE light source assembly fixture 1 is used for assembling and fixing an ASE light source assembly, and the ground debugging and testing work of the ASE light source assembly is completed through the single-path ASE light source assembly fixture 1;
2. the single-path ASE light source assembly fixture 1 is assembled on a mechanical base flat plate fixture 2, and mechanical related tests such as sine tests, random vibration tests, impact tests and the like of a plurality of ASE light source assemblies are completed through the mechanical base flat plate fixture 2;

The design makes the temperature difference between the surfaces of the single-path ASE light source assembly fixture 1 and the thermal base fixture 3 and the product smaller. The condition of the product that the thermal test of poor heat conduction capacity of frock leads to is lost efficacy excessively is reduced, the product itself has better been protected. The reliability and the safety of the product development process are improved.
The single-path ASE light source assembly fixture mainly aims at assembling and fixing an ASE light source assembly; the mechanical panel tool has the main function of bearing a plurality of single-path ASE light source assembly tools for mechanical screening test. Therefore, mechanical flat plate clamping can be realized once, and repeated labor is reduced by disassembling the single-path ASE light source assembly tool; the thermal base tool is mainly used for carrying a plurality of single-path ASE light source assembly tools to carry out thermal screening tests. The thermal base tool is also clamped once, and repeated labor is reduced by disassembling the single-path ASE light source assembly tool; other accessories mainly play a role in sealing and auxiliary protection of the tooling or products in the tooling.
In the mechanical process, the problem of amplifying the mechanical magnitude by the tool is considered, so that the thickness of the tool cannot be too thin. In the thermal vacuum process, the heat conduction problem of the tool is considered. Too thick a tooling can cause too large specific heat of the tooling, thereby being unfavorable for temperature conduction in a vacuum environment. Finally, determining the thickness of the tooling to be 5mm; size design of the tool: the utility model is as small and portable as possible while meeting the use requirement. Therefore, the 8-shaped appearance design is adopted, and a positive and negative symmetrical mounting method can be adopted when the card is mounted. The product can be realized in a limited space, and the existing space is fully utilized. The maximization of the number of the products tested at one time is realized. The product development efficiency is improved, and the economic cost of product development is directly reduced; surface black sulfuric acid oxidation treatment: in order to further improve the heat conduction and heat dissipation capacity of the tool, the surface of the tool is subjected to black sulfuric acid oxidation treatment; other designs: and the design of the mounting holes is realized, and the ASE light source assembly fixture is connected with other fixtures through 6M 2.5 threaded holes. The design of the fiber coiling guide groove: the scattered optical fiber rings are fixed through the arc grooves cut out by the four concentric circles, and the portable optical fiber coiling is realized, and meanwhile, a certain protection effect is achieved on the optical fiber.
The mechanical panel tool has the main function of bearing a plurality of single-path ASE light source assembly tools for mechanical screening test. Thickness design of the tool: the thickness was designed to be 30cm. Through simulation verification, the fundamental frequency of the mechanical flat plate design is more than 1000Hz. Therefore, the mechanical magnitude cannot be amplified, and the lightweight design of the tool is guaranteed; designing the size of a tool: the problem of clamping the tool and the problem of the quantity of bearing products are considered. Firstly, the size and the area of the mounting hole of the conventional vibration table clamping platform are considered. The size of the mounting hole should be an integer multiple of 100 cm. Secondly, the requirements of the size and the mounting hole position of the single-path ASE light source assembly tool on the reliability of the mounting card are considered. The final plate was designed to have an area size of 410 x 410cm. The design of the holes is phi 15 mounting holes, and the hole spacing is 300 x 300cm; safety and portability design: the mechanical flat plate is installed, and the problem of error touch of an ASE light source assembly tool exists in the bolt fastening process of the fastening flat plate. Because the ASE light source assembly tool is coiled with fragile optical fibers, the height of the flat plate outside the installation surface is raised so as to be beneficial to mechanical clamping of the vibrating table. Meanwhile, blind grooves are formed in two sides of the mechanical flat plate so as to facilitate the taking and carrying of the tool.
The thermal base tool is mainly used for carrying a plurality of single-path ASE light source assembly tools to carry out thermal screening tests. And (3) light weight design: in order to reduce the labor intensity and improve the reliability and safety in the process of transferring, clamping and testing, the thickness bottom plate of the thermal base tool is designed to be 5mm, and the thickness of the side wall is 3mm; surface black sulfuric acid oxidation treatment: in order to improve the heat conduction and heat dissipation capacity of the tool, the surface of the tool is subjected to black sulfuric acid oxidation treatment; sidewall pattern drawing treatment: the side wall of frock adopts the draft design scheme, has increased the security reliability of processes such as frock transportation, has increased the space of installation simultaneously, has improved the reliability of installation.
On one hand, the main functions of accessories such as the tooling cover plate are sealing, dustproof and waterproof in thermal tests; on the other hand, the safety of the transferring process is improved.
The ASE light source assembly needs to be repeatedly disassembled in the mechanical test, thermal test, debugging and testing processes, and special assembly personnel need to be specially found for fiber coiling and other works during each disassembly. Wasting a lot of time and increasing the quality risk. The modular production of the ASE light source assembly is realized through the single-path ASE light source assembly fixture, namely, all screening work of the ASE light source can be completed through one-time assembly. The various screening procedures required by the ASE light source are completed by minimizing the circulation of a module (referred to herein as a single-path ASE light source assembly fixture) among the various base sharing fixtures.
