At present, most laser surface heat treatment equipment generates laser light through a laser emitter, which generates a light spot through the scene to heat the surface of the object. However, the size of the light spot generated by this equipment is often not adjustable, making it unable to adapt to multiple usage scenarios and having poor adaptability. Utility Model Content

The output module includes a lens assembly, an output tube, and a collimator disposed at the output end of the output tube. The lens assembly includes an optical lens A and an optical lens.

[0020] To make the objectives, technical solutions, and advantages of this application clearer, the integrated tunable spot laser of this application will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only for explaining this application and are not intended to limit this application.
[0021] In the description of this application, unless otherwise stated, "a plurality of" means two or more; the terms "center," "longitudinal," "lateral," "upper," "lower," "left," "right," "inner," "outer," "front end," "rear end," "head," "tail," "vertical," "horizontal," "top," "bottom," "inner," and "outer," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this application. Furthermore, the terms "first," "second," "third," etc., are used for descriptive purposes only and should not be construed as indicating or implying relative importance.
[0022] In the description of this application, it should be noted that, unless otherwise expressly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection between two components. Those skilled in the art will understand the specific meaning of the above terms in this application based on the specific circumstances.
[0023] This application discloses an integrated adjustable spot laser, such as... Figure 1-4 As shown, the system includes a housing 1, within which a laser module 2 and an output module 3 are disposed. The output module 3 includes a lens assembly 4, an output tube 5, and a collimator 6 disposed at the output end of the output tube 5. The lens assembly 4 includes an optical lens A7 and an optical lens B8. The optical lens A7 is fixedly disposed at the output end of the output tube 5 and is perpendicular to the laser output direction. The optical lens B8 is parallel to the optical lens A7 on the same vertical plane. The optical lens A7 is fixed inside the housing 1, while the optical lens B8 slides up and down on the vertical plane. A drive component 9 is disposed inside the housing 1 for driving the optical lens B8 to slide. The drive component 9 can be a motor, a linear module, etc.
[0024] The collimator 6 consists of a flat end cap 16 and a collimating lens 17. A plano-convex lens 18 is also provided at the light outlet of the housing 1. The plano-convex lens 18 and the collimator 6 work together to make the width of the light spot meet the processing requirements.
[0025] The housing 1 is also equipped with a mounting bracket 10, which is connected to the movable end of the drive component 9. The movable optical lens B8 is mounted on the mounting bracket 10. When the drive component 9 runs, it moves the mounting bracket 10, thereby moving the optical lens B8 mounted on the mounting bracket 10. This causes the distance between the optical lens B8 and the optical lens A7 to change, thereby adjusting the size of the output light spot. This allows the system to adapt to various heating scenarios, meet different requirements of users for the light spot, improve the adaptability of the equipment, and enhance the convenience of heating materials.
[0026] The mounting bracket 10 is also equipped with a prism 11, which is tilted at a specific angle to the optical lens B8. The angle between the mirror surface of the prism 11 and the surface formed by the optical lens B8 is set to 45°.
[0027] A cooling module 12 is also provided inside the housing 1. The cooling module 12 is located between the laser module 2 and the housing 1. When the laser module 2 is running, some of the heat generated by the laser is conducted to the housing 1 by the thermally conductive silicone, and the heat generated is carried away by the cooling module 12 on the back of the housing 1, thereby achieving the effect of cooling the equipment. This ensures that the laser module 2 works in a lower temperature environment, thereby protecting the components, reducing the damage rate of the laser module 2, and increasing the service life of the laser module 2.
[0028] The housing 1 is also provided with a lens 13, which is located at the light outlet of the housing 1. The lens 13 is used to seal the device and isolate the inside of the device from the outside, thereby preventing external impurities from entering the device and causing damage or affecting the working state. The lens 13 will not affect the output effect of the laser beam.
[0029] The housing 1 is also equipped with a temperature measuring seat 14, which is set on the output tube 5. It can monitor the temperature generated by the laser module 2 during operation in real time, so that the operator can quickly know the current status of the equipment and choose whether to continue to use it or to replace it.
[0030] Multiple sets of laser modules 2 are arranged inside the housing 1. A beam combining module 15 is also arranged inside the housing 1. The beam combining module 15 integrates the laser beams of each laser module 2. The transmission optical fibers of each laser module 2 are connected to the beam combining module 15. The output laser power can be achieved by changing the number of output laser paths in each laser module 2, or by changing the laser power of the input laser in each laser module 2. Moreover, regardless of the number of input laser paths or the magnitude of the input laser power, the output laser of the beam combining module 15 is a circular flat-top light. After being collimated by the collimator 6, it becomes a beam combining laser beam with rectangular spot characteristics after passing through the optical lens B8, and the focusing focal length does not change. The power of the beam combining laser increases linearly with the increase of the number of laser beams participating in the beam combining, or increases linearly with the increase of the power of each laser participating in the beam combining.
[0031] The above description is merely a preferred embodiment of this application and is not intended to limit this application in any way. Although this application has disclosed the preferred embodiment as above, it is not intended to limit this application. Any person skilled in the art can make some modifications or alterations to the above-disclosed technical content to create equivalent embodiments without departing from the scope of the technical solution of this application. Any simple modifications, equivalent changes, and alterations made to the above embodiments based on the technical essence of this application without departing from the scope of the technical solution of this application shall still fall within the scope of the technical solution of this application.
