Description

Technical Field

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

[0002] Laser rust removal and cleaning technology, as an environmentally friendly and efficient surface treatment method, has been widely used in industrial fields such as automobile manufacturing, ship repair, machining, and cultural relic restoration due to its advantages of no chemical pollution, high rust removal precision, and minimal damage to the substrate. Among these technologies, the laser rust removal and cleaning gun, as the core execution terminal, directly affects rust removal efficiency, equipment maintenance costs, and the lifespan of the lens components, making it a key component for technological optimization within the industry.

[0003] Existing laser rust removal and cleaning guns still have some problems in practical applications. They are generally too large and too heavy. Holding and operating them for a long time can easily cause fatigue in the hands and arms of workers. In scenarios such as the narrow spaces of ship cabins and delicate work such as cultural relic restoration, the flexibility of operation is greatly reduced, which seriously affects work efficiency and rust removal accuracy.

[0004] Therefore, this application provides a self-blowing laser rust removal and cleaning gun to meet the needs. Utility Model Content

[0005] The purpose of this application is to provide a self-blowing laser rust removal and cleaning gun, which aims to solve the problems of excessive size and weight, and the fatigue of workers' hand and arm muscles caused by prolonged holding and operation.

[0006] To achieve the above objectives, this application provides the following technical solution: a self-blowing laser rust removal and cleaning gun, including a handle and a body, the handle and the body being connected, the top surface of the body having a slot, and the front and rear of the body being interconnected; The gun body has a liner plate in the slot, and there are two sets of liner plates arranged symmetrically. Between the two sets of liner plates, there are chambers and placement slots respectively. The top surface of the gun body is detachably installed with a motor housing, and a galvanometer motor is installed in the motor housing. The galvanometer motor is connected to the reflecting mirror through a galvanometer connector. Both the galvanometer connector and the reflecting mirror are located in the chamber. The gun body is detachably equipped with a protective lens assembly and a focusing lens, and the protective lens assembly and the focusing lens are located in a placement slot; The gun body is equipped with an air guide box, which contains an air guide component, and the gun body also has a cavity for air supply.

[0007] The galvanometer motor is installed in the chamber through a detachable motor housing. The protective lens group and the focusing lens are detachably fixed in the placement slot by bolts. During maintenance, only the corresponding bolts need to be unscrewed to release the limit, without disassembling the entire gun body. This reduces the time for lens replacement and motor maintenance to 1 / 3 of the original equipment, greatly improving maintenance efficiency, reducing equipment downtime, and lowering the company's operation and maintenance costs.

[0008] Preferably, the air guide box is fixed to the rear of the gun body by bolts, and a grid is provided at the end of the air guide box.

[0009] Preferably, the air guiding assembly includes a fan and a diverter plate, the diverter plate is installed at the tail of the inner liner plate, and the two sets of inner liner plates are connected by a diverter plate, and the fan is installed inside the air guiding box; A cavity is provided between the inner liner and the inner wall of the gun body, and the cavity connects to the outlet of the gun body.

[0010] Preferably, the cross-sectional shape of the manifold is triangular.

[0011] Preferably, a baffle is slidably connected inside the slot, and an inner slide and an outer slide are respectively provided on the inner liner and the gun body. A set of T-shaped levers are slidably connected on the inner slide and the outer slide, and two sets of protective plates are provided on the levers. The two sets of protective plates are respectively attached to the outer wall of the inner slide and the inner wall of the outer slide to prevent gas from overflowing from here.

[0012] To address the issue of air leakage at the slideway, a T-shaped lever and two sets of protective plates were designed. The protective plates are larger than the inner and outer slideways, and fit snugly against the outer and inner walls of the inner and outer slideways respectively. Even when the lever slides along the slideway, it completely seals any gaps, preventing airflow leakage. This design increases the airflow utilization rate within the cavity to over 95%, ensuring the strength of the airflow barrier and further enhancing the smoke and dust removal effect.

[0013] In summary, the technical effects and advantages of this utility model are as follows: This invention integrates an air guide box and air guide assembly at the rear of the gun body, eliminating the need for external blowing equipment and enabling autonomous airflow guidance. The fan draws in external gas, which is then evenly guided through a triangular flow divider into the cavity between the gun body and the inner liner plate. Finally, the gas is blown out from both sides of the protective lens assembly, forming a stable airflow barrier that effectively shields and disperses the fumes generated by laser rust removal, preventing fumes from adhering to the lens, significantly reducing the lens contamination rate, extending the service life of the protective lens assembly, and ensuring stable transmission of laser energy to guarantee the rust removal effect.

[0014] This utility model integrates the gun handle and the gun body, and integrates components such as the air guide box and motor housing into the gun body. The overall size of the device is small and lightweight, and the operator can hold and operate it with one hand. It is suitable for complex working conditions (such as confined spaces and high-altitude operations) and solves the problem of inconvenience caused by external air blowing equipment.

Detailed Implementation

[0018] 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.

[0019] Example: Reference Figure 1-6 The self-blowing laser rust removal and cleaning gun shown includes a handle 1, a gun body 2, an inner liner 3, an air guide assembly, a galvanometer assembly, a lens assembly, and an air leakage prevention assembly.

[0020] As one embodiment of this example, the gun handle 1 and the gun body 2 are integrally injection molded or bolted together. The gun body 2 is long and has a slot along its length on the top surface. The front and rear ends of the gun body 2 are interconnected (the front end is the laser output end, and the rear end is the air guide box mounting end).

[0021] As one embodiment of this example, the inner liner 3 is provided in two sets, which are symmetrically fixed in the slots of the gun body 2 (by welding or bolts). The two sets of inner liner 3 form a chamber 300 (located in the middle of the gun body 2) and a placement slot 301 (located at the front end of the gun body 2, near the laser output end). A gap is reserved between the inner liner 3 and the inner wall of the gun body 2 to form a channel 5. The two ends of the channel 5 are respectively connected to the air guide box 8 and the front outlet of the gun body 2.

[0022] As one implementation method in this embodiment, the galvanometer assembly consists of a motor housing 10 that is detachably mounted on the top surface of the gun body 2 (corresponding to the position of the chamber 300) by bolts, a galvanometer motor 11 that is fixed inside the motor housing 10, and its output shaft that is keyed to the galvanometer connector 12. The reflector 13 is bonded and fixed to the end of the galvanometer connector 12, and both the galvanometer connector 12 and the reflector 13 are located inside the chamber 300.

[0023] As one implementation method in this embodiment, the protective lens group 15 and the focusing lens 14 are both detachably installed in the placement slot 301 of the gun body 2 by bolts, and the focusing lens 14 is located on the side closer to the reflecting lens 13, and the protective lens group 15 is located on the side closer to the front end outlet of the gun body 2, forming a laser transmission path of "reflecting lens → focusing lens → protective lens group".

[0024] As one embodiment of this invention, the air guide assembly consists of an air guide box 8 fixed to the rear of the gun body 2 by bolts, with a grid at its end (used to filter impurities in the air and prevent them from entering the cavity 5); a fan 9 fixed inside the air guide box 8 by a clip (the fan power supply is electrically connected to the switch on the gun handle 1, and the switch controls its start and stop); a diverter plate 4 with a triangular cross-section is welded and fixed to the rear of two sets of inner lining plates 3, and the two sets of inner lining plates 3 are connected as one unit through the diverter plate 4, with the tip of the diverter plate 4 facing the air guide box 8, used to evenly divert the airflow output by the fan 9 to the cavities 5 on both sides.

[0025] As one embodiment of this invention, the air leakage prevention component includes: a baffle (used to assist in fixing the lens assembly, not shown in the figure) slidably connected inside the placement groove 301; an inner slide 200 on the inner liner 3; and an outer slide 302 on the gun body 2 corresponding to the inner slide 200. The cross-section of the lever 6 is T-shaped, with its vertical section sliding through the inner slide 200 and the outer slide 302, and its horizontal section located outside the gun body 2 (for easy operation by the operator). Two sets of protective plates 7 are provided, respectively bonded and fixed to both sides of the vertical section of the lever 6. The size of the protective plates 7 is larger than the size of the inner slide 200 and the outer slide 302, ensuring that when the lever 6 slides along the slide, the two sets of protective plates 7 always fit against the outer wall of the inner slide 200 and the inner wall of the outer slide 302, sealing the gaps in the slide and preventing air leakage.

[0026] The working principle of this utility model is as follows: Pressing the switch on the handle 1 allows the laser beam to pass through an optical fiber into a collimating lens for diameter adjustment before being directly input to a reflecting lens 13. The galvanometer motor 11 drives the galvanometer connector 12 and the reflecting lens 13 to swing left and right, causing the laser beam to be reflected towards the focusing lens 14. After being focused by the focusing lens 14, the laser beam is output through the protective lens group 15. Cleaning and rust removal of object surfaces is performed within the range of rapid left-right oscillation of the laser. During the laser's action on the object surface for rust removal, a large amount of... The smoke and dust can contaminate the protective lens assembly 15. The fan 9 in the air guide box 8 at the rear of the gun body 2 draws the external gas into the air guide box 8 through the grid, and then blows the airflow to the other end of the gun body 2. The airflow passes through the splitter plate 4 and blows into the cavity 5 between the gun body 2 and the inner liner plate 3. Then it blows out from the front side of the gun body 2 (both sides of the protective lens assembly 15). The airflow output through the air cover port is a strong airflow that shields and disperses the smoke and dust, protecting the protective lens assembly 15 and improving its service life.

[0027] The lever 6, which slides within the inner slide 200 and the outer slide 302, is sealed by two sets of protective plates 7 to prevent air leakage during use and to avoid affecting the airflow intensity (the protective plates 7 are larger than the inner slide 200 and the outer slide 302, so that they can still seal the slides during the up and down sliding process).

[0028] When it is necessary to maintain or replace the protective lens group 15 and the focusing lens 14, simply unscrew the corresponding bolts to release their restriction on the gun body 2, and remove the protective lens group 15 and the focusing lens 14 from the placement slot 301. The galvanometer motor 11 can be removed from the chamber 300 simply by releasing the restriction of the motor housing 10 on the gun body 2.
