Laser ray light source assembly low in cost

Abstract

The invention relates to a laser ray light source assembly low in cost. A radial through assembling groove is arranged in the center of the top end part of a main body part of a laser head assembly and the laser head assembly is internally provided with a cylindrical lens which is distributed in a radial direction; inclined planes are symmetrically arranged on the bottom face of the assembling groove; an included angle between the central axis of the lens and a laser beam output by a laser generation assembly is tuned finely through adjusting the position of the cylindrical lens on the pair of inclined planes; when the included angle is a right angle, the two ends of the cylindrical lens are fixed by using glue. Compared with a method for adjusting by adopting four screws, the laser ray light source assembly disclosed by the invention has the characteristics of simple structure, higher debugging precision, portable and direct debugging, smaller debugging difficulty, fewer working hours and the like. The main body part of the assembly is applicable to one-time die-cast formation by aluminum casting; compared with a machining manner, the laser ray light source assembly has the characteristics of lower production cost, higher production efficiency, higher precision, easiness in controlling the quality of a product, and the like. After the cylindrical lens is fixed by glue, mechanical stress hardly exists and the reliability of the product is high.

Problems solved by technology

[0006] The disadvantages of the above-mentioned line marking instrument in the prior art are: (1) the special structure and assembly and debugging method of the hollow cylinder 5 make it necessary to adopt aluminum material with good toughness to be machined Hard and brittle cast aluminum is used to realize this structure by one-time casting molding), the processing cost is relatively high, and the production efficiency is low; (2) four screws are used to adjust the central axis of the cylindrical lens 1 and the laser beam 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
