However, the sandblasting process seriously pollutes the environment. If excessive dust is caused in the air, workers who stay in this environment for a long time may cause lung diseases.
[0003] As an alternative, the ablation effect of the laser is used to replace the sandblasting process to create the pit effect, but when a high-power laser is used to make pits in a point-touch manner, not only the energy loss is serious, but the ablation marks are too obvious, and the pits The shape of the pit is irregular and difficult to control; when the laser power is low, it is difficult to form a pit shape of a given scale on the surface, and the pit shape is also irregular and difficult to control

Embodiment Construction
[0032] Preferred embodiments of the present application are shown in the accompanying drawings. However, the application may be implemented in many different forms and is not limited to the embodiments described herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete.
[0033] It should be noted that when an element is referred to as being "fixed" to another element, it can be directly on the other element or intervening elements may also be present. When an element is referred to as being "connected" to another element, it can be directly connected to the other element or intervening elements may also be present. In contrast, when an element is referred to as being "directly on" another element, there are no intervening elements present. The terms "vertical," "horizontal," "left," "right," and similar expressions of orientation or position are used herein for purposes of illustration only.
[0034] Unless otherwise defined, all ...

Abstract
The invention relates to a method for processing pits on a metal surface. The method for processing pits on a metal surface includes: designing a graph, the graph including a circle and connecting lines, at least three nodes are evenly spaced on the circle, and each of the The connection line is connected between the node and the center of the circle, and an arc segment is formed between two adjacent nodes; the ablation path is designed according to the connection line and arc segment of the graph, and the path is not traversed repeatedly All the connecting lines and arc segments; using a laser to sequentially ablate the metal surface along the path to form pits. The method for processing pits on a metal surface can form pits with controllable shapes on the surface of an object, and the surface of the object distributed with the array formed by the pits has a uniform texture.
Description
technical field [0001] The invention relates to the technical field of laser processing, in particular to a method for processing pits on a metal surface by using a laser. Background technique [0002] The sandblasting process is often used to process the surface shape of objects. For example, the sandblasting process is used to improve the appearance of objects such as aluminum materials used in 3C products, so that some textured sand patterns are formed on the surface of the objects, and densely packed on the microscopic level. The pits are beautiful and generous macroscopically. However, the sandblasting process is seriously polluting the environment, such as causing excessive dust in the air, and workers in this environment for a long time may cause lung diseases. [0003] As an alternative, the ablation effect of the laser is used to replace the sandblasting process to create the pit effect. However, when a high-power laser is used to make pits by touch, not only the e...
