Description

Technical Field

[0001] This utility model belongs to the field of laser processing technology, specifically a laser cleaning head with adjustable angle. Background Technology

[0002] With the continuous advancement of industrial technology, laser cleaning, as a cleaning method that combines high efficiency and environmental friendliness, has received increasing attention. Laser cleaning primarily uses a high-energy laser beam to irradiate the surface of the object being cleaned, causing contaminants to evaporate, vaporize, or decompose instantly, thus achieving the cleaning purpose. It can clean dirt, rust, and coatings from various material surfaces, offering significant advantages such as excellent cleaning results, no damage to the substrate, and no environmental pollution. However, in traditional laser cleaning applications, the angle of the laser cleaning head is often fixed, which to some extent limits its flexibility and adaptability. For example, when cleaning surfaces with complex shapes or areas with different angles, traditional fixed-angle laser cleaning heads may not be able to effectively perform the cleaning work.

[0003] The existing technology still has the following shortcomings:

[0004] 1. When using existing laser cleaning heads, traditional fixed-angle laser cleaning heads may not be able to effectively clean complex-shaped object surfaces or parts at different angles. It is necessary to adjust the position of the object or use multiple cleaning heads at different angles, which not only increases the complexity of operation but also reduces cleaning efficiency.

[0005] 2. Existing laser cleaning heads lack a stable and convenient laser focal length adjustment function during use. Adjusting the laser focal length allows for more precise control of the working surface, but the complex operation and poor stability of the adjustment mechanism cannot meet current needs. Utility Model Content

[0006] To overcome the above-mentioned defects, this utility model provides a laser cleaning head with adjustable angle, which solves the problem of fixed angle of laser cleaning head.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a laser cleaning head with adjustable angle function, including an optical tube, a focal length adjustment knob is sleeved on the outer side of the optical tube, a convex lens is fixedly connected inside the focal length adjustment knob, and a rotating mechanism and a locking mechanism are provided on one side of the optical tube.

[0008] As a further embodiment of this utility model: a fixing frame is fixedly connected to both sides of the first light tube, and a second light tube is fixedly connected to one end of the two fixing frames. The outer side of the first light tube and the second light tube near the focal length adjustment knob is provided with a thread, and the inner wall of the focal length adjustment knob is provided with a thread that matches it. A light outlet is fixedly connected to one side of the second light tube.

[0009] As a further embodiment of this utility model: a reflective lens is fixedly connected inside the light tube, and a limit ring is fixedly connected to one side of the light tube.

[0010] As a further embodiment of this utility model: a light tube is rotatably connected to one side of the limiting ring.

[0011] As a further embodiment of this utility model: a sleeve is fixedly connected to the upper part of the optical tube three, a spring is provided inside the sleeve, a fixed base is fixedly connected to the upper part of the optical tube three, a limiting plate is fixedly connected to the upper part of the sleeve, the limiting plate is rotatably connected to the fixed base, and a limiting block on one side of the limiting plate is adapted to the groove on the limiting ring.

[0012] As a further embodiment of this utility model: a scanning galvanometer is fixedly connected inside the optical tube three, and a laser is fixedly connected inside the optical tube three.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0014] 1. By setting a rotation adjustment mechanism and a limiting mechanism between the first and second optical tubes, the variable laser output angle is realized, which can meet the needs of cleaning the surface of objects with complex shapes or parts with different angles, reducing the complexity of operation and improving the cleaning efficiency.

[0015] 2. By adjusting the position of the convex lens using the adjustment knob, the focal length of the laser can be adjusted, enabling precise control of the working surface and avoiding negative impacts of the laser on non-working surfaces. At the same time, this equipment has a simple and stable structure, low cost, and effectively reduces the equipment cost for enterprises. Attached Figure Description

[0020] The technical solution of this patent will be further described in detail below with reference to specific embodiments.

[0021] like Figures 1-3 As shown, this utility model provides a technical solution:

[0022] A laser cleaning head with adjustable angle function includes an optical tube 1, characterized in that a focal length adjustment knob 2 is sleeved on the outside of the optical tube 1, a convex lens 14 is fixedly connected inside the focal length adjustment knob 2, and a rotating mechanism and a locking mechanism are provided on one side of the optical tube 1.

[0023] Specifically, by rotating the focus adjustment knob 2, its position on the optical tube is adjusted, thereby achieving the function of adjusting the position of the convex lens 14;

[0024] A fixing frame 6 is fixedly connected to both sides of the light tube 1. A light tube 2 3 is fixedly connected to one end of the two fixing frames 6. Threads are provided on the outer side of the light tube 1 and light tube 2 3 near the focal length adjustment knob 2. A matching thread is provided on the inner wall of the focal length adjustment knob 2. A light outlet 5 is fixedly connected to one side of the light tube 2 3.

[0025] Specifically, the first optical tube 1 and the second optical tube 3 are fixedly connected by the fixing bracket 6, and the focus adjustment knob 2 is connected to the first optical tube 1 and the second optical tube 3 by the thread. Rotating the focus adjustment knob 2 can adjust its position on the optical tube.

[0026] A reflective lens 11 is fixedly connected inside the light tube 1, and a limit ring 4 is fixedly connected to one side of the light tube 1.

[0027] Specifically, the angle of the laser changes as it passes through the reflecting mirror 11, becoming parallel to the optical tube 2 3.

[0028] A light tube 10 is rotatably connected to one side of the limiting ring 4;

[0029] Specifically, the third light tube 10 is rotatably connected to the limiting ring 4, while the first light tube 1 is fixedly connected to the limiting ring 4. Rotating the first light tube 1 allows for the adjustment of the angle of the first light tube 1.

[0030] A sleeve 9 is fixedly connected to the top of the optical tube 3 10. A spring 15 is installed inside the sleeve 9. A fixed base 8 is fixedly connected to the top of the optical tube 3 10. A limit plate 7 is fixedly connected to the top of the sleeve 9. The limit plate 7 is rotatably connected to the fixed base 8. The limit block on one side of the limit plate 7 is adapted to the groove on the limit ring 4.

[0031] Specifically, press the limiting plate 7 to retract the sleeve 9 and the spring 15. The end of the limiting plate 7 near the limiting ring 4 will lift up. After adjusting the light tube 1, release the limiting plate 7 so that the limiting block at one end of the limiting plate 7 is stuck in the groove on the limiting ring 4 to complete the fixation.

[0033] Specifically, the laser emitted by the laser 13 is moved and positioned rapidly by the scanning galvanometer 12.

[0034] The working principle of this utility model is as follows:

[0035] First, start the laser 13. The laser emitted by the laser 13 passes through the scanning galvanometer 12. The angle of the laser changes as it passes through the reflecting lens 11, becoming parallel to the second laser tube 3. When it is necessary to adjust the laser angle, press the limiting plate 7 to retract the sleeve 9 and the spring 15. The end of the limiting plate 7 near the limiting ring 4 will lift up. After adjusting the first laser tube 1, release the limiting plate 7 so that the limiting block at one end of the limiting plate 7 is locked in the groove on the limiting ring 4, thus completing the adjustment of the laser angle. When it is necessary to adjust the laser working surface, rotate the focus adjustment knob 2 to adjust its position on the laser tube, which will move the convex lens 14 to achieve the function of adjusting the laser working surface.
