[0024] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the scope of the present utility model.

[0025] like Figures 1 to 6 As shown, this embodiment provides a lens protection and environmental protection device for use on a laser cleaning head, including a mounting body 1, a splash isolation plate 2, a lens protection power mechanism 7, and an air duct 3; the mounting body 1 is detachably mounted on the side of the laser cleaning head 13 that emits laser; the upper end of the mounting body 1 is provided with a splash isolation plate 2, which extends into the laser emission path of the laser cleaning head 13, and a narrow slit 5 for the laser to pass through is provided on the splash isolation plate 2 facing the laser emission path; the mounting body 1 is provided with an air duct 3 that runs through its upper and lower ends, and the lens protection power mechanism 7 is provided in the air duct 3.

[0026] In this embodiment, the mounting body 1 has two parallel air ducts 3, each containing a lens protection power mechanism 7. The lower end of the mounting body 1 has a dust collection port 4 communicating with the air ducts 3, and at least one air duct 3 is connected to the dust collection port 4. The dust collection port 4 is connected to an external fume purifier via a dust collection pipe. The two air ducts 3 and the two lens protection power mechanisms 7 are combined in pairs to form two sets of lens protection channels, one of which shares an air duct 3 with the lower dust collection port 4.

[0027] When the laser cleaning head 13 emits laser light to clean the workpiece 14, it generates a large amount of smoke and dust. This smoke and dust not only pollutes the environment and the workpiece 14, but also contaminates the lenses of the laser cleaning head 13, thus affecting the cleaning effect. Therefore, in actual use, two lens protection channels can be set up simultaneously according to actual needs, or one of the lens protection channels can be used in conjunction with the dust collection port 4 and the fume purifier. For routine paint and rust removal of the workpiece, a combination of lens protection channel and dust collection fume purification can be used. For situations where the workpiece is highly viscous and has high splash kinetic energy after degreasing and cleaning, two lens protection channels can be used simultaneously to enhance the lens protection effect.

[0028] A splash isolation plate 2 is installed between the mounting body 1 and the laser cleaning head 13. The splash isolation plate 2 is located between the workpiece 14 to be cleaned and the laser cleaning head 13. The splash isolation plate 2 has a narrow elliptical slit 5, which ensures that the laser emitted by the laser cleaning head 13 can pass through the narrow slit 5 and reach the cleaning position of the workpiece 14 to be cleaned (i.e., Figure 6 In the laser cleaning action area 17), when the laser cleaning head 13 cleans the workpiece 14, most of the generated fumes can be blocked by the spatter isolation plate 2. Figure 6 In the potential dust accumulation area 15), a small amount of dust may enter between the splash isolation plate 2 and the laser cleaning head 13 through the narrow slit 5. Figure 6 The potential diffusion area of ​​smoke and dust is 16). To prevent a small amount of smoke and dust from entering the space between the splash isolation plate 2 and the laser cleaning head 13 through the narrow gap 5 and contaminating the lens, the main body 1 is equipped with an air duct 3 and a lens protection power mechanism 7. The lens protection power mechanism 7 draws the smoke and dust into the air duct 3 and discharges it, thus preventing the smoke and dust from spreading between the splash isolation plate 2 and the laser cleaning head 13. The smoke and dust blocked outside settles towards the dust collection port 4 under its own gravity, is collected by the huge suction generated by the smoke purifier, and is discharged after filtration, reducing environmental pollution.

[0029] In this embodiment, in order to ensure that the dust entering between the splash isolation plate 2 and the laser cleaning head 13 through the narrow slit 5 can smoothly enter the air duct 3, a dust diversion plate 6 is provided between the splash isolation plate 2 and the laser cleaning head 13. The dust diversion plate 6 is inclined and its lower end extends to the upper end of the air duct 3. When the lens protection power mechanism 7 is working, the wind force is concentrated to cut off the movement of dust and directly suck the dust into the air duct 3, so as to prevent it from moving to the lens and contaminating the lens.

[0030] like Figure 7 and Figure 8As shown, in this embodiment, the mounting body 1 is detachably and movably connected to the laser cleaning head 13 via a connecting fixture. The connecting fixture includes a fixture body 8 and fasteners 9. The fixture body 8 has multiple elongated holes 10 penetrating its opposite sides at both ends.

[0031] The outer wall of the mounting body 1 is provided with multiple sets of first connecting holes evenly spaced along the vertical direction. Each set of first connecting holes includes multiple sets of first connecting holes 11 evenly spaced along the horizontal direction. Fasteners 9 pass through the elongated hole 10 and the corresponding first connecting hole 11 at one end of the tooling body 8 to fix the mounting body 1 to the tooling body 8. The outer wall of the laser cleaning head 13 is provided with multiple sets of second connecting holes evenly spaced along the vertical direction. Each set of second connecting holes includes multiple sets of second connecting holes 12 evenly spaced along the horizontal direction. Fasteners 9 pass through the elongated hole 10 and the corresponding second connecting hole 12 at the other end of the tooling body 8 to fix the laser cleaning head 13 to the tooling body 8.

[0032] During installation, the fixture body 8 is placed tightly against the outer wall of the laser cleaning head 13 and the mounting body 1. The distance and vertical height between the laser cleaning head 13 and the mounting body 1 are adjusted according to actual needs, aligning the elongated hole 10 with the appropriate first connecting hole 11 and second connecting hole 12. Fasteners 9 are then passed through the connecting holes and elongated holes 10 to securely connect the laser cleaning head 13 and the mounting body 1 to the fixture body 8, thus achieving the connection between the laser cleaning head 13 and the mounting body 1. When it is necessary to adjust the installation distance and / or installation height between the laser cleaning head 13 and the mounting body 1, the fasteners 9 are removed, the elongated hole 10 is realigned with the appropriate connecting hole, and then fastened again using the fasteners 9. Specifically, the number of elongated holes 10, the first connecting hole group, the first connecting hole 11, the second connecting hole group, and the second connecting hole 12 can be selected according to actual needs to better meet specific requirements.

[0033] By adopting the above-disclosed technical solution of this utility model, the following beneficial effects are obtained:

[0034] This invention provides a lens protection and environmental protection device for laser cleaning heads. The device automatically cleans the lenses, prevents contamination, and improves the durability and safety of the laser cleaning head in complex environments. It also collects and treats waste gas and residue generated during the cleaning process, reducing environmental pollution, while providing safety protection to ensure the safety of operators.

[0035] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
