Embodiment Construction

[0012] specific implementation plan

[0013] figure 1 It is a laser diode strip sealing and welding jig shown in the invention patent application 201310172914. Among them, 010 is the base of the fixture. 011 is the adjustment jacking screw of briquetting block 012. The pressure block 012 is used to press and fix the diode strip 018 to be welded and the combination of the two sealing and welding heat sink blocks 016 and 017 in the up and down direction (referred to as the thickness direction of the combination). Usually two relatively thin pieces of solder, such as indium, are sandwiched between the diode strip and the two heat sinks ( figure 1 not shown in the figure 2 ). The combined width of the diode strip 018 and the two heat sink blocks 016 and 017 is d, that is, 020. 014 is the pressing block in the width direction of the above combination, and 015 is the adjustment of the pressing block 014 in the sealing and welding combination d Direction on the top tightening ...

Abstract

The invention relates to a large power laser diode palladium bar seal welding clamp. According to the seal welding clamp, a press block having an adjustable inclination angle and adjustable weight slides up and down on an inclination surface to generate a special push-press force which is utilized to apply press on a seal welding laser diode palladium bar assembly. The push-press force automatically stays stable in a seal welding process and does not change along with dimension change of the seal welding assembly caused by solder fusing, a manual error is small, and the seal welding clamp is convenient to use and operate.

Description

technical field [0001] The fusion welding packaging technology between the laser diode slab and the heat sink mechanical parts and the mold fixture used. [0002] technical background [0003] Laser diode strips usually need to be welded and mounted on the corresponding heat sink mechanical structure, and then provided to end-use customers. In the process of fusion welding and mounting, how to ensure that the diode slats do not cause warping and deformation mechanically, and do not cause pollution and damage to the light-emitting end face of the diode, and how to have a good heat conduction combination between the slats and the heat sink mechanical parts is the main problem that needs to be faced. technical challenge. [0004] A typical method is shown in the invention patent application 201310172914, which uses a mold fixture, uses fasteners such as adjusting screws to align the diode strips with the heat sink mechanical parts, and then tightens them together, and then heat...
