Description

Technical Field

[0001] The invention relates to the technical field of axle cleaning, and in particular to a large-area axle paint cleaning device based on a composite laser cleaning head. Background Art

[0002] Compared with traditional mechanical and chemical cleaning, laser cleaning technology, as a new environmentally friendly cleaning technology, has the advantages of non-contact, high efficiency and no pollution. It is widely used in aerospace, rail vehicles, petroleum, chemical industry, shipbuilding and other fields.

[0003] Currently, lasers are divided into two types according to the control method: pulse lasers and continuous lasers.

[0004] Using a single type of pulsed laser for cleaning will have certain defects in cleaning efficiency and cleaning effect. For example, when using a single pulsed laser for cleaning, due to its own performance limitations, the energy density generated is low, resulting in low cleaning efficiency and incomplete cleaning, especially for materials with thick paint layers, the cleaning effect is very poor.

[0005] On the other hand, although a single continuous laser cleaning can clean the dirt or rust layer, the energy generated by the laser often exceeds the threshold of substrate ablation, causing damage to the substrate itself, thus failing to achieve the expected cleaning effect.

Therefore, the directional terms used are for better and clearer explanation and understanding of the embodiments of the present invention, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the embodiments of the present invention.

[0043] Example 1

[0044] Reference Figure 1-Figure 9The present embodiment is a large-area axle paint cleaning device based on a composite laser cleaning head, which mainly includes a composite laser cleaning head and a working platform 9. The composite laser cleaning head is exquisitely designed and integrates the dual functions of continuous laser and pulse laser to achieve efficient cleaning of axle paint.

[0045] The specific structure of the composite laser cleaning head is as follows:

[0046] like Figure 2 and Figure 3 As shown, the handheld composite laser cleaning head includes a continuous laser component 11, a pulse laser component 12, a laser gun body 13, an air curtain 14, an air pipe 15, a dust suction port 16, a connector 17 and other components. The continuous laser component 11 and the pulse laser component 12 are respectively located on both sides of one end of the gun body 13, and the continuous laser 1 and the pulse laser 2 are connected to the two components through optical fibers and then enter the interior of the gun body 13.

[0047] Inside the gun body 13, the collimating lenses 3 and 4 respectively converge the scattered continuous laser and pulse laser into parallel light, which is then converged into one point through the focusing lens 7 to achieve accurate cleaning of the axle paint. In order to prevent the slag from splashing and contaminating the lens during the cleaning process, an air curtain 14 is specially designed, which can form an air knife-like airflow at the front end of the gun body 13 to effectively prevent the slag from splashing.

[0048] like Figure 4 As shown, the upper end of the connector 17 is provided with an air pipe 15 and a dust suction port 16. The air pipe 15 is connected to an air valve for blowing air to the surface of the workpiece 8 to remove the residue on the surface. The dust suction port 16 is connected to a dust suction system, and the paint particles are completely absorbed by the suction device to avoid environmental pollution. In order to ensure the dustproof effect of the laser head and increase the service life of the galvanometer, each installation joint is sealed with a sealing ring.

[0049] The gas connected to the gas pipe 15 can be an inert gas, such as nitrogen (N2), carbon dioxide (CO2) and argon (Ar2), etc. These gases not only help cleaning, but also prevent pollution caused by chemical reactions.

[0050] like Figure 4 As shown, in addition, the composite laser cleaning head also includes a dust removal mechanism and a suction mechanism. The dust removal mechanism is installed on the connector 17, and is connected to the suction mechanism through the dust suction port 16 and the connecting pipe 18 to realize dust suction on the surface of the workpiece. The suction mechanism includes a card cover 19, a hose 20 and a connecting box 21 and other components that are mounted on the connecting pipe 18. A collection component and a power component are arranged in the connecting box 21. The collection component is used to collect the suctioned residue, and the power component provides suction and knocks the collection component to prevent it from being blocked.

[0051] like Figure 4 and Figure 5As shown, the collecting assembly includes a cover plate 22 that passes through the opening of the connecting box 21 and fits tightly with the opening, and a collecting bucket 23 fixed on one side of the cover plate 22. A plurality of filter holes 24 are evenly spaced on the inner wall of the inclined surface of the collecting bucket 23 for filtering residues. The power assembly includes components such as an external pipe 25, a power box 26, an air inlet 27, an impeller component and a knocking component. The external pipe 25 is used to connect to an external air intake pipe, and an impeller component is installed in the power box 26. The impeller component is connected to the cam 30 through a rotating shaft 28, and the cam 30 cooperates with the knocking component. When the external air intake pipe provides suction, the impeller component rotates and drives the cam 30 to rotate, thereby driving the knocking component to knock on the collecting bucket 23 to prevent blockage.

[0052] like Figure 8 As shown, the knocking member includes a support plate 35, an L-shaped transmission plate 36, a stopper tube 37, a hammer rod 38, and a buffer spring 39, which are slidably connected in the connection box 21. When the cam 30 rotates to contact the L-shaped transmission plate 36, the support plate 35 is pushed to move downward and the compression spring 33 is compressed; when the cam 30 is out of contact with the L-shaped transmission plate 36, the compression spring 33 pushes the support plate 35 to move upward and drives the hammer rod 38 to knock the collection bucket 23. The buffer spring 39 provides buffer protection to prevent the collection bucket 23 from being damaged by strong impact.

[0053] Example 2

[0054] Reference Figure 10-11 This embodiment is based on the first embodiment. Regarding the paint cleaning equipment for cleaning a large area of ​​a workpiece 8 based on a composite laser cleaning head proposed in the first embodiment, in order to clamp and position the workpiece 8, the working platform 9 includes a moving base 91, an H-shaped frame 92, an adjusting column 93, a table 94, a first mounting plate 95, a second mounting plate 96, a stepping motor 97, a first chuck 98, a support frame 99, an adjusting plate 910, a moving rod 911, a second chuck 912, an adjusting screw 914, an adjusting nut 913 and other components. The workpiece 8 can be clamped and rotated by the stepping motor 97 and the adjusting screw 914; the height of the table 94 can be adjusted by the adjusting column 93 and the driving screw 917.

[0055] During the specific implementation process, the workpiece 8 is first clamped between the first chuck 98 and the second chuck 912 by the stepper motor 97 and the adjusting screw 914; then the laser cleaning head is started to clean the workpiece 8; at the same time, the synchronous belt 919 is pulled to adjust the height of the table 94 as needed; during the cleaning process, the dust suction system sucks the residue into the collection bucket 23 through the dust suction port 16 and the connecting pipe 18; when the external suction pipe provides suction, the power component drives the knocking component to knock the collection bucket 23 to prevent blockage; finally, after the cleaning is completed, the equipment is turned off and the workpiece 8 is taken out for subsequent processing.

[0056] In addition, a mounting shaft 40 and a baffle 41 are fixedly mounted on the top of one side of the connection box 21. The baffle 41 can be rotated to limit and unlock the cover 22; at the same time, the baffle 41 is elastically limited by the torsion spring 34 to ensure that it always vertically limits the cover 22 stably.

[0057] Working principle: first, place the workpiece 8 between the first chuck 98 and the second chuck 912. Then, the adjusting screw 914 can be rotated to drive the adjusting plate 910 to move under the threaded transmission action of the adjusting nut 913, and the second chuck 912 can be driven to approach the workpiece 8 through the moving rod 911, until the workpiece 8 can be positioned and clamped with the cooperation of the first chuck 98. Then, according to the height adapted by the operator, the synchronous belt 919 can be pulled to drive the two synchronous wheels 918 to rotate. When the synchronous wheels 918 rotate, the transmission nut 916 can be driven to rotate, so that the transmission screw 917 can be moved longitudinally under the threaded transmission cooperation with the corresponding transmission screw 917, so that the height of the table 4 can be adjusted, so that the workpiece 8 can be adjusted to a height matching the operator. Then, the focusing lens 7 is adjusted to adjust the focal position so that it focuses on The surface of the workpiece 8, the laser parameters are input into the computer 10, and the continuous laser and pulse laser light are controlled by software. The continuous laser 1 is connected to the continuous laser head assembly 11 through the optical fiber interface QBH, and the laser beam is irradiated onto the first reflector 5 through the first collimator 3, and then irradiated onto the second reflector 6 connected to the vibration motor through the first reflector 5. The vibration motor swings at a high frequency, and the laser beam is transmitted from the focusing lens 7 to finally form a "straight line" laser scanning surface that is irradiated onto the workpiece 8 located on the working platform 9; the pulse laser 2 is connected to the pulse laser head assembly 12 through the optical fiber interface QBH, and the laser beam is irradiated onto the first reflector 5 through the second collimator 4, and then irradiated onto the second reflector 6 connected to the vibration motor through the first reflector 5. The vibration motor swings at a high frequency, and also forms a "straight line" laser scanning surface after being transmitted from the focusing lens 7 to irradiate the workpiece 8 located on the working platform 9. The pulse laser is located after the continuous laser;

[0058] Fig. 9A is in front of the cleaning direction and is the scanning surface of the continuous laser. Its laser energy is large. As the front cleaning position, it can roughly clean the cleaning layer and leave a thin layer of residue. This can effectively prevent the uncontrollable factors of excessive energy from damaging the workpiece 8; B is behind the cleaning direction, that is, right behind A. It is the scanning surface of the pulsed laser. Its laser energy is relatively small, and the previous continuous laser can make a certain preheating preparation for the next pulsed laser, which increases the absorption rate of the pulsed laser to the removed layer. Therefore, the scanning surface B of the pulsed laser can finely clean the thin layer residue after A cleaning without damaging the workpiece 8. Therefore, the composite cleaning of the two laser beams can not only improve the cleaning efficiency, but also ensure the cleaning quality.

[0059] At the same time, the air curtain 14 forms an air knife-like airflow and blows it toward the upper end of the lens, which can effectively prevent the cleaning slag from splashing and contaminating the lens. The residue on the surface of the workpiece 8 can be removed by blowing air through the air blowing pipes 15 on both sides to ensure the cleanliness of the surface of the workpiece 8. Then, the paint particles are completely absorbed by the suction device to avoid environmental pollution. Then, the dust suction system is connected through the dust suction port 16, and the dust collector absorbs the paint impurities to prevent the paint from floating and polluting the environment.

[0060] The composite laser cleaning head device can also be used with a robot arm. The laser head is installed on the robot arm, and automatic cleaning is achieved through robot programming.

[0061] When the workpiece 8 is cleaned, the stepping motor 97 can be started to drive the first chuck 98 to rotate, so that the workpiece 8 can be rotated and adjusted, thereby achieving comprehensive cleaning of the workpiece 8;

[0062] When it is necessary to collect the residue on the workpiece 8, the dust suction port 16 can be attached to the workpiece 8, and then the external pipe 25 can be connected to the external suction pipe. At this time, the residue within the range of the dust suction port 16 can be sucked out and transported to the collection bucket 23 through the hose 20 to collect the residue. When the gas passes through the power box 26, it can impact the axial flow blades 29, so that the axial flow blades 29 can rotate, which can drive the rotating shaft 28 to rotate. When the rotating shaft 28 rotates, the cam 30 can rotate. When the cam 30 contacts the L-shaped transmission plate 36, the cam 30 in the state can drive the L-shaped transmission plate 36 to drive the support plate 35 When the cam 30 is disengaged from the L-shaped transmission plate 36, the two compression springs 33 under stress can push the support plate 35 to move upward, thereby driving a plurality of hammer rods 38 to move upward, thereby striking the collecting bucket 23. When the hammer rods 38 strike the collecting bucket 23, the filter holes 24 can be prevented from being blocked, thereby ensuring the normal flow of gas. At the same time, the buffer springs 39 can provide buffering protection for the hammer rods 38 to prevent the collecting bucket 23 from being damaged by strong impact.

[0063] However, as is well known to those skilled in the art, the working principles and wiring methods of the continuous laser 1, pulsed laser 2 and computer 10 are commonplace, and are conventional means or common knowledge, and will not be elaborated here. Those skilled in the art may make any optional selections according to their needs or convenience.

[0064] The above are only specific embodiments of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art can easily think of changes or substitutions within the technical scope disclosed by the present invention, which should be included in the protection scope of the present invention; the embodiments of the present invention and the features in the embodiments can be combined with each other without conflict.
