Clamp for welding optical communication component through laser tin soldering

Abstract

The invention relates to a clamp for welding an optical communication component through laser tin soldering, which is used for positioning a circuit board and a flexible board and comprises a workbench and a fixing assembly, a first clamping groove and a second clamping groove are formed in the workbench, the first clamping groove and the second clamping groove are partially overlapped to form a welding area, the circuit board is embedded in the first clamping groove, the flexible board is embedded in the second clamping groove, and the parts, located in the welding area, of the circuit board and the flexible board are stacked; the fixing assembly is fixedly connected with the workbench, the fixing assembly is provided with a fixing end capable of moving relative to the workbench, when the fixing end moves to a first position, the fixing end, the first clamping groove and the second clamping groove form a clamping gap, and when the fixing end moves to a second position, the clamping gap is formed between the first clamping groove and the second clamping groove. The fixed end, the first clamping groove and the second clamping groove are arranged in a staggered mode. An existing fixture for welding and fixing a circuit board and a flexible board adopts a complicated structure in order to realize good positioning and fixing effects, and is inconvenient to adjust and low in working efficiency.

Description

technical field [0001] The invention relates to the technical field of laser welding fixtures, in particular to a fixture for laser soldering and welding optical communication components. Background technique [0002] Laser welding is an efficient and precise welding method that uses a high-energy-density laser beam as a heat source. The welding process is a heat conduction type, that is, the laser radiation heats the surface of the workpiece, and the surface heat diffuses to the interior through heat conduction. By controlling the parameters such as the width, energy, peak power and repetition frequency of the laser pulse, the workpiece is melted to form a specific molten pool. Among them, optical communication components have higher welding density and higher precision. Since the flexible board in optical communication components can be flexibly bent, aligning the flexible board with the circuit board is a difficult problem in the welding process. [0003] In order to sol...
