Description

Technical Field

[0001] The utility model belongs to the technical field of workpiece surface positioning marking equipment, and in particular relates to a portable handheld laser marking device. Background Art

[0002] In modern manufacturing, laser marking machines are widely used for surface marking of metals, plastics and other materials due to their advantages such as high precision, non-contact and permanent marking. However, traditional laser marking machines are mainly desktop, and their operational flexibility and convenience are limited, especially when dealing with large or irregular workpieces. In order to improve the flexibility of laser marking, handheld laser marking machines have gradually become the focus of market demand.

[0003] Although the existing handheld laser marking machines have improved in flexibility, they still have many technical problems. For example, the dust generated during the marking process can easily contaminate the field lens, affecting the marking quality and the service life of the equipment; the lack of stability during handheld operation can easily cause the mark to shift; in addition, the safety of laser operation also needs to be improved to prevent the laser from causing harm to the operator and surrounding personnel.

[0004] Publication No. CN220560661U discloses a safety protection fixed focus frame for a handheld laser marking machine, including a marking head body, a field lens, a fixed focus frame body, a detection switch, and an anti-slip strip. The field lens is provided at the bottom center of the marking head body, and a fixed focus frame body is provided at the bottom of the marking head body and outside the field lens. A dustproof component is provided on the fixed focus frame body, and an observation component is provided in the middle of one side of the outer surface of the fixed focus frame body. The utility model has the following beneficial effects: through the design of the dustproof component of the present application, when the present invention is marking, a positive pressure airflow is formed above the fixed focus frame body, and the airflow moves from top to bottom to form a protective air curtain, which can effectively isolate the marking dust and prevent it from contaminating the field lens. Through the design of the observation component, during the marking process of the present invention, the marking status can be viewed at any time through the central observation window, and at the same time, the eyes of the observer are effectively protected to prevent the laser from causing harm to the observer.
