Description

Technical Field

[0001] This utility model relates to the field of laser marking technology on the surface of shielding covers, and in particular to a laser marking device for the surface of shielding covers. Background Technology

[0002] In the field of modern electronic product manufacturing, shielding covers, as an important electromagnetic interference (EMI) shielding component, are widely used on the PCB boards of electronic devices such as mobile phones, tablets, and communication modules. In order to achieve accurate traceability and quality control of shielding covers, it is usually necessary to use laser marking technology to engrave permanent markings containing information such as model number, batch number, and manufacturer information on their surface.

[0003] However, the laser marking head of most traditional equipment is installed in a fixed position, and its focal depth is limited. When switching between shields of different heights, the workpiece surface can easily deviate from the optimal focal plane of the laser, resulting in blurry and indistinct marking effects that fail to meet quality requirements. To solve this problem, operators have to stop the machine and manually readjust the height of the laser head, a time-consuming and labor-intensive process that severely impacts production efficiency and equipment utilization. Utility Model Content

[0004] Based on this, the present invention provides a laser marking device for the surface of a shield. It has a simple structure and is easy to use. Through the coordinated action of the lifting cylinder and the lifting motor, the shield and the laser marking device can be driven to lift as a whole, quickly and accurately adjusting the laser focal length to adapt to the shield surface at different heights. This ensures that the marking is always at the optimal focus plane and effectively solves the problem of blurry marking caused by changes in height.
