Description

Technical Field

[0001] The utility model belongs to the technical field of laser engraving equipment, and in particular relates to a laser engraving detection device. Background Art

[0002] At present, laser engraving technology is one of the largest application areas of laser processing. Laser engraving is to use laser beams to mark the surface of various materials permanently. Specifically, it is a surface processing technology that uses laser technology to write text and patterns on objects. The words engraved by this technology have no scratches, the surface of the object is still smooth, and the patterns and handwriting are clear. It has a wide range of applications and can adapt to a variety of material characteristics. It is inexpensive; and it uses non-contact processing, which will not cause mechanical extrusion or stress on the material, there are no processing marks, and generally will not cause material deformation. The processing accuracy can generally reach 0.02mm; it can also ensure that the processing effects of the same batch of products are completely consistent and there is no obvious difference. Therefore, laser engraving technology provides a simple method for permanent anti-wear marking on workpieces.

[0003] In the existing Chinese patent literature, there is no lack of relevant technical information on facilities and equipment for realizing laser marking, a few of which are: CN213827520U (a laser marking machine), CN215034530U (a laser marking machine that is easy to adjust), CN113146035B (a laser marking device), CN103448378B (laser marking machine), etc.; for example, the patent with authorization announcement number CN209078041U discloses a laser marking machine that is easy to adjust. The laser marking machine that is easy to adjust has powerful functions, scientific design, and has the advantages of convenient operation, good stability, high reliability and suitability for wide promotion; for example, the "laser marking device that is easy to transfer workpieces" disclosed in the authorization announcement number CN210789678U is easy to collect and organize the workpieces, and improves the continuity of the marking process, thereby speeding up the production progress of the workpieces and improving the production efficiency. The structure is scientific and reasonable, and it is safe and convenient to use. However, existing laser engraving equipment has certain disadvantages when in use: first, most of the current laser engraving equipment has the problem of complex component structure and large number of components, resulting in high assembly and production costs. At the same time, most of the current laser engraving equipment cannot automatically realize the continuous replacement of products, and manual replacement by staff is time-consuming and labor-intensive, which takes a lot of time, resulting in poor stability and low fluency when the equipment performs laser engraving processing on the product; secondly, in the working process of the existing laser engraving equipment, specialized technicians are required to operate the laser equipment to engrave the product, and visual inspection is required to confirm the product status, and the position of the laser engraving is adjusted at the same time, which will result in long-term occupancy of the laser engraving equipment. It affects other processing processes, and the entire operation process also requires a high level of technical skills from the staff, resulting in an increase in production costs; in addition, since each engraving process requires manual operation, and manual operation cannot accurately and efficiently locate and identify the position of the product engraving, this makes the engraving stability performance poor and has a certain adverse effect on the use process. In the working process, since there are many similar products at the same time, and there are dimensional requirements for the size and position of the engraving, due to the large unstable factors of people, this leads to low overall work efficiency and easy mistakes, and it is easy to produce defective products and related safety hazards. At the same time, the existing equipment cannot automatically and quickly perform precise detection of products, thereby affecting the application effect of the laser engraving machine.

[0004] In view of the above situation, it is necessary to design a laser marking device with simple structure, high working efficiency, automatic laser marking and reduced need for manual operation. To this end, the applicant has made a useful design, and the technical solution to be introduced below is produced under this background. Utility Model Content
