Embodiment Construction

[0032] The present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments.

[0033] figure 1 It is a schematic diagram of a collimator grid structure 1 that needs to be welded in the present invention. It is mainly composed of a plurality of grid structure units 2, and each grid structure unit 2 is internally composed of numerous transverse metal foils 21, The vertical metal foil 22 is formed, and the intersection position of the horizontal and vertical metal foils is the welding position 23 . The length and width of a single grid structure are on the order of millimeters, and the material of the metal foil is usually selected from metals such as tungsten and tantalum, and the thickness is on the order of tens of microns. There are nearly 10,000 solder joints in each grid structure, and the parallelism and perpendicularity must be guaranteed within 1 angular minute. In a preferred embodiment, the material of the meta...

Abstract

The invention discloses a collimator grid structure laser precision welding device and method, wherein the welding device includes: a laser, a beam shaping system, a dynamic focus scanning system, a visual detection system, an XY numerical control work platform, a Z-direction motion axis, and a welding purification system. system, auxiliary welding equipment, and related control systems. The dynamic focus scanning system is fixed on the Z axis, the collimator grid is fixed on the XY CNC work platform, the control system can use the visual inspection system to detect the welding position of the grid, and drive the XY CNC work platform to calibrate and adjust the position. The control system can also drive and control the laser beam to realize scanning motion and dynamic focusing, and weld the grid structure. The device and method provided by the present invention meet the requirements of precise manufacturing of high-performance and lightweight devices such as collimator grid structures, accurate welding positioning, less welding heat input, small deformation, high efficiency and reliability, and a high degree of automation.

Description

technical field [0001] The invention relates to a laser precision welding device and method for a grid structure of a collimator, belonging to the field of laser welding processing. Background technique [0002] High-precision collimators are key components in fields such as deep space exploration, pulsar navigation, and medical devices. The collimator is composed of a collimator metal frame body and a metal foil grid unit inserted on the body. The overall structure of the collimator is on the order of meters, the size of the grid is on the order of millimeters, and the thickness of the foil is on the order of microns. The collimator grid structure is a typical cross-scale precision component, with a large number of solder joints, and a single component has nearly 10,000 solder joints. Orthogonally interleaved metal foils form a grid unit structure. The material is usually tungsten, tantalum and other metals. The thickness of the foil is tens of microns. The parallelism an...
