[0027] The technical solution of the present utility model is further described in detail below through specific implementation methods.

[0028] like Figure 1 and Figure 2 As shown, a laser cleaning device for the surface of an anode steel claw guide rod includes a laser emission module, which includes two laser light sources 1, two groups of laser galvanometers 2 and a field lens 3.

[0029] Generally speaking, it also includes a frame 5 and a driving module 6 installed in the frame 5. The driving module 6 is used to drive the laser emission module to move in a set travel path. In this embodiment, the driving module 6 can be set to at least one level of linear motion platform, which mainly completes the lifting and lowering movement of a specific area. In other embodiments, multiple levels of motion platforms can be added to complete lateral movement and movement in other required directions.

[0030] In other embodiments, the number of laser light sources and matching laser galvanometers can be set to be greater. Generally, the amount of laser light will increase with the increase in the number of light sources, but due to the size limitation of the equipment, the number of laser light sources must be limited, but its number can be specifically determined based on the scale of the equipment and the size of the retained space.

[0031] The laser beams emitted by the laser light sources 1 are parallel to each other and in the same direction, and are generally transmitted through optical fibers to avoid light loss as much as possible.

[0032] The laser galvanometer 2 is used to receive the laser beams emitted by each laser light source 1 and guide the laser light to the field lens 3; the field lens 3 is used to emit the received laser light as parallel light to form a laser cleaning beam 4.

[0033] The laser galvanometer 2 and the field lens 3 are essential structures in the laser cleaning equipment and are existing technologies.

[0034] In this embodiment, the two groups of laser light sources have the same specifications and output parameters, and the laser wavelength is 1000 nm-1100 nm, preferably 1060 nm-1080 nm.

[0035] In other embodiments, the specifications of the laser light sources in each group can also be different, and the laser output parameters can be different, and the wavelengths can be selected as needed.

[0036] Embodiment 1

[0037] In this embodiment, the formed laser cleaning beam 4 is two groups of beams superimposed together after the action of the laser galvanometer 2 and the field lens 3. The light quantity in the superimposed state is greatly increased, the light intensity is increased to a certain extent, and the cleaning ability is enhanced.

[0038] Embodiment 2

[0039] In this embodiment, the formed laser cleaning beam 4 is two groups of beams superimposed together after the action of the laser galvanometer 2 and the field lens 3. The light quantity in the superimposed state is greatly increased, the light intensity is increased to a certain extent, and the cleaning ability is enhanced.

[0040] Technical principle explanation:

[0041] The basic principle of laser cleaning is to use laser to gasify, peel, decompose and vibrate the dirty substances on the surface of the guide rod. Therefore, the size of the laser light quantity will affect the cleaning effect.

[0042] Under the traditional scheme, the laser is usually scanned in sequence, and the number of scans is increased to complete the cleaning task. However, due to the slow walking during the cleaning process, the efficiency is affected, and the dirty substances that have not been completely removed during the secondary cleaning process will re-condense and adhere, which will significantly increase the consumption of laser energy. Therefore, the multiple cleaning method is a helpless choice.

[0043] After the transformation of the new scheme, the laser light quantity is doubled by directly increasing the laser light source and using the same field lens to emit it. The effect will be significantly enhanced, most of the cleaning tasks can be completed at one time, and a small amount of thick area can be scanned twice. Compared with the traditional scheme, the efficiency is greatly improved.

[0044] When working, the guide rod 7 is suspended by the catenary system 8 through the cleaning station. The rack 5 is provided with a position detection sensor 9, and the control module is connected to the position detection sensor for obtaining the position signal of the guide rod. The guide rod 7 is temporarily stopped for cleaning.

[0045] The driving module 6 drives the laser emission module to scan the surface of the guide rod, that is, to complete the cleaning work.

[0046] In other embodiments, in order to improve the flexibility and scope of the cleaning device, a laser power detection module and a control module are further included, the laser power detection module is used to detect the output power of the laser emission module, and the control module is used to adjust the output power of the laser emission module, and different output powers are executed for different cleaning objects.

[0047] In preferred other embodiments, a guide rod surface finish detection module is further included, and the control module is connected with the guide rod surface finish detection module to collect the guide rod surface finish, and then control the opening and closing of the laser emission module and the opening and closing of the driving module, which is used as an inspection function after laser cleaning, and can also be used as a pre-checking work of the anode guide rod in the early stage, and is used to determine the range that needs to be cleaned.

[0048] Finally, it should be noted that: the above embodiments are only used to illustrate the technical solutions of the present application, but not to limit them; although the present application has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that: the specific embodiments of the present application can still be modified or some technical features can be replaced by equivalents; without departing from the spirit of the technical scheme of the present application, all of them should be covered in the technical scheme range of the present application claimed by the present application.
