High-production-efficiency laser linear light source assembly and assembly method thereof

Abstract

The invention relates to a laser linear light source assembly and an assembly method thereof. The center of the top end of a main body of a laser head assembly is provided with a radially-penetrative assembly groove, and a cylindrical lens is radially distributed in the assembly groove; the bottom surface of the assembly groove is symmetrically provided with a slope; the included angle between the central axis of the lens and the laser beam output by the laser generation assembly is finely adjusted by adjusting the position of the cylindrical lens on the slope; and when the included angle is a right angle, both ends of the cylindrical lens are fixed by glue. Compared with the four-screw adjustment method, the invention has the characteristics of simple structure, higher adjustment precision, convenient and visual adjustment, low adjustment difficulty, fewer working hours and the like. The main body of the assembly is suitable for cast aluminum one-step pressure casting; and compared with the machining mode, the cast aluminum one-step pressure casting has the characteristics of low production cost, high production efficiency, high precision, controllable product quality and the like. After the cylindrical lens is fixed by the glue, almost no mechanical stress exists, and thus, the reliability of the product is higher.

Problems solved by technology

[0006] The weak point of the marking instrument in the above-mentioned prior art is: (1) the special structure and the assembling and debugging mode of the described hollow cylinder 5 make it necessary to adopt aluminum material with better toughness to be machined Hard, relatively brittle cast aluminum realizes this structure by one-time casting molding), the processing cost is higher, and the production efficiency is lower; (2) adopt four screws to adjust the central axis of the cylindrical lens 1 and the laser generating The included angle of the laser beam output by the component is difficult to debug; (3) After the assembly and debugging are completed, there is mechanical stress at the connecting block 7 of the laser head component, which causes the above-mentioned existing laser line light source to be in use. Part 6 is prone to loosening or metal deformation, which leads to a non-right angle between the central axis of the cylindrical lens 1 and the output laser beam of the laser generating assembly, which in turn causes the laser line output by the laser line light source to appear arc-shaped ,Affect
