Description

Technical Field

[0001] This utility model relates to the field of laser rust removal equipment technology, and in particular to a novel self-blowing laser rust removal and cleaning gun. Background Technology

[0002] Laser cleaning technology, as an advanced and green cleaning process, has developed rapidly in recent years. Compared with traditional mechanical grinding and chemical corrosion cleaning methods, laser cleaning has shown great potential in precision manufacturing and high-end applications, especially in removing rust, paint, and oil stains from metal surfaces, due to its advantages such as non-contact, non-abrasive, no thermal effect, and applicability to various substrates. Handheld laser cleaning guns have become the mainstream equipment in the market due to their flexible operation and good accessibility, and the technology is becoming increasingly mature. However, existing handheld laser cleaning guns generate a large amount of high-temperature fumes and metal vapor particles at the moment the laser ablates the material surface. These fumes inevitably adhere to and sinter on the protective lens at the very tip of the gun, causing the lens's light transmittance to drop rapidly. This not only affects the cleaning effect but also causes overheating damage to the lens due to the absorption of laser energy, greatly shortening its service life and increasing the user's consumable costs and equipment downtime for maintenance.

[0003] Therefore, this application provides a novel self-blowing laser rust removal and cleaning gun to meet the needs. Utility Model Content

[0004] The purpose of this application is to provide a novel self-blowing laser rust removal and cleaning gun, which aims to solve the problem that existing handheld laser cleaning guns cause short lifespan and high maintenance costs due to the pollution of protective lenses by the smoke and dust generated during operation.

[0005] To achieve the above objectives, this application provides the following technical solution: a novel self-blowing laser rust removal and cleaning gun, comprising a handle and a gun body connected to the handle; One end of the gun body is connected to a wind shield, the other end is connected to a galvanometer motor, and a fan is provided on the top of the gun body; The gun body is provided with a reflective lens, a focusing lens, and a protective lens arranged sequentially along the optical path through a galvanometer connector. The gun body is also equipped with an air duct. The inlet of the air duct is connected to the air outlet of the fan, and the outlet of the air duct is connected to the laser output port of the gun body. Through the cooperation between the above components, the smoke and dust generated during the cleaning process can be actively blown away and isolated when the laser is working, thereby effectively protecting the optical lens at the front end.

[0006] Preferably, the gun body further includes an outer shell and an inner shell, and the gap between the outer shell and the inner shell forms the air duct, making the gun body structure compact, eliminating the need for additional pipelines, and simplifying the production and assembly process.

[0007] Preferably, the inner outer shell below the fan has a guide arc surface to smoothly guide the airflow generated by the fan to the air duct, effectively reducing the energy loss of the airflow and ensuring that the airflow delivered to the outlet is stable and strong.

[0008] Preferably, it further includes a slidable protective shield assembly, which is mounted on the gun body and located between the laser output port of the gun body and the protective lens.

[0009] Preferably, the gun body is provided with a guide hole for the sliding of the protective shield assembly, and the protective shield assembly includes a shield for closing the laser output port and a windproof plate for sealing the guide hole when closed, thereby achieving dual protection for the gun body and comprehensively improving the protection level and reliability of the whole machine.

[0010] In summary, the technical effects and advantages of this utility model are as follows: In this invention, a fan is installed on the top of the gun body, and an integrated internal air duct is cleverly formed by utilizing the gap between the outer shell and the inner shell. The outlet of this air duct is connected to the laser output port. This design can spray a powerful high-speed airflow in front of the protective lens when the laser is working. This airflow can not only build a protective barrier, but also actively and continuously blow away and isolate the high-temperature fumes generated during the cleaning process, thereby greatly reducing the adhesion of contaminants on the lens surface, significantly extending the service life of the protective lens, and reducing maintenance costs.

[0011] In this invention, a sliding protective shield assembly is provided. This assembly can completely seal the laser output port through its shield, and its wind baffle can also seal the guide hole, providing a reliable physical seal for the equipment during standby or storage, thus comprehensively improving the equipment's adaptability to harsh working conditions and the overall reliability of the machine.

[0012] In this invention, the air duct is perfectly integrated with the shell structure of the gun body, and an air guide arc surface is provided to optimize the airflow path. No external pipes or additional components are required, making the overall gun structure compact, rationally laid out, and simple in appearance. This not only ensures an excellent human-machine grip experience, but also simplifies the production and assembly process, and has high practical value and economy. Attached Figure Description

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model. Example

[0017] refer to Figure 1-5 The novel self-blowing laser rust removal and cleaning gun shown includes a handle 1 that is easy for the user to hold and a gun body 2 connected to the handle 1. The external layout of the gun body 2 is compact and reasonable. One end of the gun body 2 is connected to a wind shield 3 for regulating airflow, and the other end is connected to a galvanometer motor 5 for driving the beam to swing. A fan 4 for generating protective airflow is installed on the top of the gun body 2.

[0018] As one implementation method in this embodiment, the gun body 2 adopts an ingenious double-shell design, which includes an outer shell 21 and an inner shell 23. The gap between the outer shell 21 and the inner shell 23 is precisely designed to form a closed and symmetrical air duct 28. This design, which integrates the air duct 28 with the structure of the gun body 2, greatly saves space and enables the gun body to achieve efficient airflow without the need for additional external pipelines.

[0019] As one implementation method in this embodiment, the core optical components inside the gun body 2 are all installed in the inner outer shell 23. To facilitate installation and maintenance, a lens mounting port 24 is provided on the inner outer shell 23. The focusing lens 7 and the protective lens 6 are installed through the lens mounting port 24. A reflective lens 27 for reflecting the light path is also provided inside the inner outer shell 23. The reflective lens 27 is precisely located between the focusing lens 7 and the galvanometer motor 5, and the reflective lens 27 is connected to the output shaft of the galvanometer motor 5 through a galvanometer connector 26, thereby realizing the high-speed swing of the lens driven by the motor.

[0020] As one implementation method in this embodiment, in order to maximize airflow efficiency, the top of the inner outer shell 23 below the fan 4 is provided with a guide arc surface 25. When the fan 4 is working, the guide arc surface 25 can smoothly and evenly divert the vertically downward airflow to the air duct 28 inlet on both sides of the gun body, effectively reducing the energy loss and turbulence of the airflow, and ensuring that the airflow delivered to the outlet is stable and strong.

[0021] As one embodiment of this invention, a sliding protective shield assembly 8 is included. This assembly is mounted on the gun body 2 and is positioned between the laser output port 22 of the gun body 2 and the protective lens 6. To enable the sliding function of this assembly, a guide hole 29 is provided on the gun body 2 for sliding, and a cavity is reserved inside the gun body 2 above the laser output port 2 for the shield 83 to be fully housed. The protective shield assembly 8 includes a lever 81 for easy push-pull operation by the user, a shield 83 for closing or opening the laser output port 22, and a wind deflector 82 for completely covering and sealing the guide hole 29 when closed, effectively preventing dust.

[0022] The working principle of this device is as follows: When performing cleaning and rust removal operations, the operator presses the switch on handle 1. The laser beam enters the gun body through an optical fiber, is reflected by the reflector 27, and then passes through the focusing lens 7 and the protective lens 6 before exiting from the laser output port 22. Simultaneously, the galvanometer motor 5 drives the reflector 27 to swing at high speed through the galvanometer connector 26, causing the laser beam to scan rapidly within the working area. During this process, the fan 4 starts synchronously, generating a powerful airflow. The airflow is guided by the air guide arc surface 25 into the air ducts 28 on both sides, and finally sprays a powerful, high-speed airflow into the working area through the air cover 3. This airflow not only constructs a protective barrier in front of the protective lens 6, but also actively and continuously disperses and isolates the high-temperature fumes generated during the cleaning process, preventing them from contacting and contaminating the protective lens 6. When the equipment is not in use, the operator can operate the lever 81 to slide the protective shield assembly 8, causing the shield 83 to slide down to completely seal the laser output port 22. At the same time, the wind baffle 82 seals the guide hole 29, thereby providing reliable physical dust protection for the internal precision optical components.

[0024] Components not described in detail in this article are existing technologies.

[0025] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
