Description

Technical Field

[0001] This utility model relates to the field of laser engraving technology, specifically a laser engraving electrostatic dust removal device. Background Technology

[0002] Laser marking technology, due to its permanent, clear, and efficient marking with minimal damage to workpieces, has been widely used for surface marking and information traceability of products such as electronic components, medical devices, and precision tools. High-quality laser marking requires a clean and dust-free workpiece surface. Any tiny dust, oil, or particulate matter adhering to the marking area will cause abnormal absorption or scattering of laser energy, resulting in defects such as blurred markings, uneven depth, and edge burrs, which seriously affect the readability of the markings and product quality.

[0003] Currently, on laser engraving production lines, dust removal is usually treated as an independent process, and it generally faces the following technical bottlenecks: the separation of dust removal from the engraving process poses a risk of secondary pollution; uneven static dust removal coverage creates dead zones; and the equipment lacks flexibility and cannot adapt to changing working conditions.

[0004] Therefore, there is an urgent need in this field to deeply integrate and synchronize the dust removal process with the engraving process to achieve precise follow-up dust removal; at the same time, the device should have high flexibility and be able to flexibly configure the number and spacing of dust removal points according to the needs of the workpiece and process, so as to fundamentally solve the laser engraving quality problem caused by dust pollution and improve production yield and efficiency.

[0023] The position adjustment mechanism 4 includes a first motor 401 mounted on the top frame 302. The output shaft of the first motor 401 is fixedly connected to a first threaded rod 402. The first threaded rod 402 is rotatably connected to the top frame 302. The first threaded rod 402 is threadedly connected to a movable frame 403. The movable frame 403 is slidably connected to the top frame 302. The top frame 302 is fixedly connected to a slide rod 404. The slide rod 404 passes through the movable frame 403.

The second threaded rod 406 is threadedly connected to a movable block 407. The movable block 407 is slidably connected to the movable frame 403.

[0024] Specifically, turning on the first motor 401 will drive the first threaded rod 402 to rotate, thereby causing the moving frame 403 to move along the axis of the slide rod 404. Turning on the second motor 405 will drive the second threaded rod 406 to rotate, thereby causing the moving block 407 to move along the moving frame 403, and then causing the first linear motor 5 and the laser engraving head 6 to move and change position.

[0028] In the implementation of this utility model, after the workpiece to be laser-engraved is placed on the engraving table 1, the height of the lifting frame mechanism 9 is adjusted according to the different heights of the workpiece. At the same time, according to the different sizes of the workpiece, a specified number of electrostatic adsorption mechanisms 10 are installed on the lifting frame mechanism 9, and the spacing of the electrostatic adsorption mechanisms 10 is controlled.

Combined with a first linear motor 5, it enables laser engraving at different positions on the workpiece.
