Abstract
Description
Technical Field
[0001] This utility model relates to the field of laser cutting equipment technology, and in particular to a dust cover for optical devices. Background Technology
[0002] Laser cutting involves focusing a laser beam emitted from a laser source into a high-power-density beam through a laser optical path system. This beam irradiates the workpiece surface, causing it to reach its melting or boiling point. Simultaneously, high-pressure gas coaxial with the beam blows away the molten or vaporized metal. As the relative position of the beam and the workpiece moves, a kerf is formed in the material, achieving the cutting purpose. Laser cutting uses an invisible beam of light instead of a traditional mechanical blade, offering advantages such as high precision, fast cutting speed, no limitation on cutting patterns, automatic layout to save material, smooth cuts, and low processing costs.
[0003] Currently, laser optical path systems include laser generating devices, laser transmission devices, and laser focusing devices arranged in sequence. Among them, the laser transmission device contains a number of optical lenses. If the lenses are directly exposed to the air, they are very easy to attract dust, oil, or other contaminants, which are difficult to clean, thus making the optical lenses dirty and adversely affecting the transmission of laser light. Utility Model Content

The dustproof frame is formed with a wide frame section and a narrow frame section corresponding to the arrangement of the laser transmission devices. An inner corner post and a flat corner post are provided between the wide frame section and the narrow frame section to connect the two, so that the wide frame section and the narrow frame section enclose both ends of the laser transmission device.
[0007] The wide frame surrounds one end of the laser transmission device and forms three first outer corner pillars arranged in pairs opposite to the flat corner pillars, and four first dustproof plates arranged between any one of the first outer corner pillars and an adjacent first outer corner pillar, inner corner pillar, or flat corner pillar; the narrow frame surrounds the other end of the laser transmission device and forms two second outer corner pillars arranged in pairs opposite to the inner corner pillars and flat corner pillars, and three second dustproof plates arranged between any one of the second outer corner pillars and an adjacent second outer corner pillar, inner corner pillar, or flat corner pillar; the top cover is detachably mounted on the top of the wide frame and the narrow frame to enclose the laser transmission device.
[0008] As a further technical solution of this utility model: the inner corner column, the flat corner column, the first outer corner column and the second outer corner column all form a base for connecting with the base plate and two intersecting insertion arms connected to the base; wherein, the two insertion arms of the inner corner column, the first outer corner column and the second outer corner column intersect at right angles, and the two insertion arms of the flat corner column intersect at flat angles.
[0009] As a further technical solution of this utility model: each insertion arm has an insertion groove on its outer side, and a first sealing strip is provided in the insertion groove, so that the side of the first dustproof plate or the second dustproof plate can be inserted into the insertion groove. The first sealing strip fits the side of the first dustproof plate or the second dustproof plate to achieve dustproof sealing.
