Description

Technical Field

[0001] This utility model relates to the field of laser engraving technology, and in particular to a device for detecting laser engraved patterns. Background Technology

[0002] Laser engraving machines use laser beams to create permanent marks on the surfaces of various materials. The marking effect is achieved by evaporating the surface material to expose the deeper material, by causing chemical and physical changes in the surface material through light energy to create marks, or by burning away part of the material with light energy to reveal the desired etched patterns or text. When inspecting these markings, a laser engraving pattern detection device is required.

[0003] According to Chinese Patent Application No. CN202222250431.6, a device for detecting laser-engraved patterns is proposed. A part is placed on a base plate, and a bracket is mounted on the base plate. A camera assembly is mounted on the upper part of the bracket, and several light source assemblies are mounted on the lower part of the bracket. The part is located within the area enclosed by the light source assemblies. The laser head is directly below the camera assembly, and the camera assembly is directly below the part. Using a camera replaces manual inspection, improving inspection accuracy and increasing the degree of freedom in adjusting the camera and light sources, adapting to the inspection of products with different structures. This application also proposes another technical solution to address the problem that commonly used camera structures can only be adjusted vertically, failing to meet the inspection needs of complex product structures.

[0006] The detection assembly includes a housing, a servo motor, a rotating shaft, a limiting plate, a limiting groove, a limiting block, a camera, and a lighting lamp. The housing is located at the moving end of the front linear module three. The servo motor is located on the inner wall of the housing. The rotating shaft is coaxially connected to the output shaft of the servo motor via a coupling, and its other end extends through and to the bottom of the housing. The limiting plate is located on the rotating shaft. The limiting groove is located on the outer side of the housing. The limiting block is located on the limiting plate and is slidably connected to the inner wall of the limiting groove. The camera is located at the bottom of the limiting plate, and the lighting lamp is located on the camera.

[0007] Optionally, there may be multiple linear modules, with intervals between them.

[0008] Optionally, there may be multiple linear modules two, and there may be intervals between the multiple linear modules two.

[0009] Optionally, there may be multiple linear modules three, with intervals between the multiple linear modules three.

[0010] Optionally, both the limiting groove and the limiting block are arranged in a ring shape.

[0011] Optionally, the number of the lighting lamps is multiple, and the multiple lighting lamps are arranged in a ring on the camera.

[0012] The technical solution of this utility model has the following beneficial effects: When it is necessary to perform multi-directional detection of the laser-engraved pattern on the workpiece, the camera is first adjusted to the top of the workpiece through linear module one, linear module two, and linear module three. Then, the servo motor is started to drive the camera on the limit plate to pass through the limit groove and the limit block for stable positioning. In addition, with the fine adjustment of linear module one, linear module two, and linear module three, the laser-engraved pattern on the workpiece can be detected from multiple angles. Furthermore, the workpiece can be supplemented with lighting by a lamp that follows the angle of the camera, thereby improving the accuracy of the detection. Attached Figure Description
