Description

Technical Field

[0001] The utility model relates to the technical field of laser processing equipment, in particular to a laser head protective mirror drawer structure. Background Art

[0002] Laser equipment is used in nearly every sector of industrial production, from light to heavy industry, from energy and power to integrated circuits, from electronic communications to medical aesthetics, from shipbuilding and automotive to aerospace. As a cutting-edge technology in materials processing, lasers offer unlimited potential for development. Producing superior laser heads has become a crucial issue in the laser industry, involving numerous details. Improving the lifespan of core lenses is crucial to extending the lifespan of the entire laser head.

[0003] Since the procurement cost of the core lens in the laser head is usually relatively high, in order to protect the core lens from contamination as much as possible, protective lenses are usually installed on both sides of the core lens. The protective lens needs to be replaced after being contaminated. Currently, the most common structure is a drawer-type structure; specifically, the protective lens is placed on the protective lens drawer, and then pressed and fixed by the protective lens pressure ring, and then the protective lens drawer is inserted into the laser head for use. However, the existing protective lens drawer lacks a structure to limit the protective lens, and the protective lens is usually rigidly placed on the protective lens drawer; during the processing, since the laser head needs to move constantly, this can easily cause the protective lens to shake in the protective lens drawer, resulting in poor processing, or even the protective lens being broken and damaged, increasing production costs.

[0018] References to "embodiments" in this disclosure mean that a particular feature, structure, or characteristic described in connection with the embodiment may be included in at least one embodiment of the disclosure. The appearance of this phrase in various places in the specification does not necessarily refer to the same embodiment, nor does it necessarily refer to mutually exclusive, independent, or alternative embodiments to other embodiments. It is understood, both explicitly and implicitly, by those skilled in the art that the embodiments described in this disclosure may be combined with other embodiments.

[0019] In order to enable those skilled in the art to better understand the solution of the present invention, the technical solution in the embodiment of the present invention will be clearly and completely described below with reference to the accompanying drawings.

[0020] like Figure 1-3 As shown, a laser head protective lens drawer structure includes a drawer seat 1. The drawer seat 1 is a hollow structure and is provided with an optical path through hole for the laser light to pass through. The drawer seat 1 is installed with a pan seal 2, a protective lens 3 and a protective lens pressure ring 4. The outer wall of the pan seal 2 is sealed and abutted against the inner wall of the drawer seat 1. The protective lens 3 is placed on the pan seal 2, and the lower end face of the protective lens 3 is limited by the upper end face of the pan seal 2. The protective lens pressure ring 4 is installed on the drawer seat 1 to limit the position. The outer wall of the protective lens pressure ring 4 is sealed and abutted against the inner wall of the drawer seat 1, and the upper end face of the protective lens 3 is abutted against the lower end face of the protective lens pressure ring 4. The protective lens 3 is limited in the drawer seat 1 by the protective lens pressure ring 4 and the pan seal 2 to ensure the stability of its overall structure.

[0021] An elastic limiting ring 5 is also provided in the drawer seat 1, which is in limiting contact with the outer wall of the protective lens 3. The elastic limiting ring 5 is used to provide lateral limiting force to the protective lens 3; by providing an elastic limiting ring 5 in the drawer seat 1, the side of the protective lens 3 can be limited, thereby avoiding the shaking of the protective lens 3 during processing, improving the processing stability, and also extending the service life of the protective lens 3 and reducing production costs.

[0022] Specifically, a mounting groove 11 is provided in the drawer seat 1, and the elastic limit ring 5 is fixed in the mounting groove 11, and a notch is provided on the side wall of the mounting groove 11, which is connected to the optical path through hole in the drawer; after the laser head protective lens drawer is assembled, the elastic limit ring 5 abuts against the protective lens 3 through the notch, thereby achieving the function of limiting the protective lens 3.

[0023] To facilitate assembly, a gland 6 is also installed on the drawer base 1. The gland 6 is detachably connected to the drawer base 1 and is used to cover the installation groove 11, thereby limiting the elastic limiting ring 5 in the installation groove 11. After the elastic limiting ring 5 is installed, the gland 6 can be connected to the upper end surface of the elastic limiting ring 5. The elastic limiting ring 5 is enclosed in the installation groove 11 by the gland 6, which can prevent the elastic limiting ring 5 from shifting during use and improve the stability of the structure. At the same time, the gland 6 and the drawer base 1 are detachably connected, which also makes it easy to install and replace the elastic limiting ring 5.

[0024] In this embodiment, the gland 6 is provided with a retaining hole 61, within which a fixing screw 7 is threadedly connected to the drawer base 1. The fixing screw 7 and the gland 6 are removably secured. The fixing screw 7 secures the gland 6 to the drawer base 1, thereby encapsulating the elastic retaining ring 5 on the drawer base 1 and ensuring structural stability. In other embodiments, the gland 6 may be connected to the drawer base 1 using other means, such as a snap-fit ​​connection.

[0025] In order to provide better protection for the protective lens 3, the protective lens pressure ring 4 is made of flexible material, and a limiting groove 41 is provided on the lower end face of the protective lens pressure ring 4. The protective lens 3 and the limiting installation are in the limiting groove 41, and the upper end face of the protective lens 3 abuts against the end face of the limiting groove 41, and the side wall of the protective lens 3 abuts against the inner side wall of the limiting groove 41; by providing the limiting groove 41 on the protective lens pressure ring 4, after the protective lens 3 is installed, the outer circumferential direction of the protective lens 3 is wrapped by the protective lens pressure ring 4, and the protective lens pressure ring 4 can provide better protection for the protective lens 3, further reducing the risk of the protective lens 3 being broken due to shaking, and improving the service life of the protective lens 3.

[0026] In this embodiment, the pan seal 2 is made of an elastic material, such as rubber. The pan seal 2 made of an elastic material provides protection for the lower end surface of the protective lens 3, allowing for flexible contact between the protective lens 3 and the pan seal 2. This reduces the risk of the protective lens 3 breaking due to operational vibration, extends the service life of the protective lens 3, and reduces costs.

[0027] The laser head protective lens drawer is used to be installed on a laser head. To facilitate installation, handle grooves 12 are symmetrically provided on the left and right side walls of the drawer base 1. The handle grooves 12 make it easier for the user to hold the drawer base 1, improving practicality. During installation, the user can hold the handle grooves 12 to secure the drawer base 1, making it easier to assemble the laser head protective lens drawer and install it on the laser head.

[0028] The above-mentioned specific implementation manner is a preferred implementation manner of the present utility model, and is not intended to limit the specific implementation scope of the present utility model. The scope of the present utility model includes but is not limited to the specific implementation manner. All equivalent changes made in accordance with the present utility model are within the protection scope of the present utility model.
