Description

Technical Field

[0001] This invention relates to the field of laser rust removal technology for steel components, and more specifically, to a laser rust removal device for steel components. Background Technology

[0002] Steel components are prone to reacting with oxygen to form iron oxide (commonly known as rust). Therefore, rust removal is an essential step in the use of steel components. There are various existing methods for rust removal of steel components, such as grinding, sandblasting, and laser treatment. Among them, laser rust removal is widely used because of its good rust removal effect and high efficiency.

[0003] Current laser rust removal methods typically involve handheld laser guns reciprocating over steel components. This is because a single laser scan cannot completely remove rust. The principle of laser rust removal is to focus light to vaporize and vibrate the steel parts. Handheld methods cannot guarantee the stability of the laser focus, and the scanning position is unstable due to repeated scanning. Furthermore, during the laser vaporization process, rust produces fumes containing metal particles and rust fragments, which can be harmful to human health. The fumes and rust fragments generated by existing laser rust removal methods are prone to clogging filters during collection. Therefore, structural optimization is necessary to address these issues. Summary of the Invention

[0004] This invention provides a laser rust removal device for steel components, which solves the problem in related technologies that laser rust removal devices cannot stably focus on the steel components to achieve efficient rust removal, as well as the technical problem that the filter device is easily clogged during the dust removal process.

The rotation of the fan impeller generates airflow, and the airflow passes through the feeding grid to adsorb the top of the rust removal platform. This collects the fumes and debris generated by the laser scanning gun during laser rust removal to the top of the industrial filter cloth for filtration. By setting a vibration dust removal mechanism to vibrate the industrial filter cloth in real time, the fumes and debris can be prevented from clogging the industrial filter cloth.

[0020] 2. This invention delivers airflow generated by the fan impeller to the interior of the support chamber, and then drives the laser scanning gun to move back and forth through the action of transmission components. This allows the laser emitted by the laser scanning gun to uniformly remove rust from the steel components. In the rust removal process, the airflow generated by the fan impeller is utilized to the maximum efficiency, thus achieving energy saving. Attached Figure Description

[0043] The dust removal mechanism 2 is equipped with a vibration dust removal component. The vibration dust removal component includes a dust collection bin 201 located at the bottom center of the rust removal platform 1. The top of the inner wall of the dust collection bin 201 is elastically supported by a support frame 204. An industrial filter cloth 206 is located in the middle of the support frame 204. A discharge guide plate 205 is located at the bottom of one end of the front of the support frame 204 inside the dust collection bin 201. The support frame 204 has a sloping structure and is inclined to the top of the discharge guide plate 205.

[0044] A fan assembly is installed on the outside of the dust removal mechanism 2.

A threaded sleeve block 217 is fitted on the outer side of the reciprocating screw 211. A vibration protrusion that matches the bottom of the industrial filter cloth 206 is provided on the top of the threaded sleeve block 217. 218, the vibrating protrusion 218 is used to vibrate and remove dust from the bottom of the industrial filter cloth 206. Both ends of the first drive shaft 207 are provided with first incomplete gears 213. The bottom of the support frame 204 is provided with a rack 212 that intermittently meshes with the first incomplete gears 213. A drive motor 203, which is connected to the first drive shaft 207, is provided on the outside of the dust collection bin 201. A transmission unit 208 is provided between the output end of the drive motor 203 and the fan impeller 209. The bottom of the vibrating protrusion 218 is provided with a second spring 220 that is internally connected to the threaded sleeve 217. The dust collection bin... The inner wall of 201 is slidably connected to both sides of the slide rod 210. The slide rod 210 passes through the threaded sleeve block 217 and the vibration protrusion 218. The threaded sleeve block 217 and the vibration protrusion 218 slide and displace on the outside of the slide rod 210. The two ends of the slide rod 210 are symmetrically provided with limit blocks 214. The upper and lower ends of the limit blocks 214 are hollow structures, and a limit protrusion 219 is provided on one side of the inner wall of the limit blocks 214. The bottom of the support frame 204 is provided with a connecting rod 216 corresponding to the limit blocks 214. A limit wedge block 215 adapted to the limit protrusion 219 is provided on the bottom of one side of the connecting rod 216.

[0045] The process of using the laser rust removal device for steel components proposed in this embodiment is as follows: When the rust removal device is in use, the steel component that needs to be rusted is placed on the top of the workbench 7, and then the longitudinal displacement unit 11 and the height adjustment unit 12 are adjusted so that the laser gun body displacement mechanism 9 drives the laser scanning gun 8 to align with the steel component. At this time, the waste port 3 and the dust collection bin 201 are closed.

[0046] The drive motor 203 is started to drive the first transmission shaft 207 and the transmission unit 208 to rotate. The rotation of the first transmission shaft 207 drives the reciprocating screw 211 and the first incomplete gear 213 to rotate, thereby causing the threaded sleeve block 217 to move outside the reciprocating screw 211. At this time, the threaded sleeve block 217 is restricted by the slide rod 210, so that the threaded sleeve block 217 moves back along the horizontal direction of the reciprocating screw 211 and drives the vibrating protrusion 218 to follow the displacement.

[0047] The rotation of the first incomplete gear 213 drives the meshing rack 212 to move downward. At this time, the rack 212 drives the support frame 204 to move downward as well. As the support frame 204 moves downward, the connecting rod 216 moves downward synchronously, causing the bottom of the connecting rod 216 to insert into the limiting block 214. At this time, the limiting wedge 215 exerts a pushing force on the limiting protrusion 219, causing the limiting block 214 to drive the sliding rod 210 to move downward as a whole. The sliding rod 210 then drives the vibrating protrusion 218 to move into the threaded sleeve 217 and compress the second spring 220. When the slide bar 210 is moved to the lowest position, the limiting wedge block 215 follows the displacement of the connecting rod 216 and squeezes through the obstruction of the limiting protrusion 219, thereby relieving the downward pressure on the slide bar 210. At the same time, the vibrating protrusion 218 is simultaneously subjected to the rebound force of the second spring 220, which instantaneously strikes the bottom of the industrial filter cloth 206, realizing the effect of local vibration dust removal on the bottom of the industrial filter cloth 206. In conjunction with the horizontal displacement of the vibrating protrusion 218 following the threaded sleeve block 217, the vibrating protrusion 218 can achieve a reciprocating multi-position vibration dust removal effect on the bottom of the industrial filter cloth 206.

[0048] When the first incomplete gear 213 rotates and no longer meshes with the rack 212, the support frame 204, under the action of the rebound force of the support spring 221, drives the rack 212 and the connecting rod 216 to reset. As the connecting rod 216 moves upward, the limiting wedge block 215 breaks through the blocking of the limiting protrusion 219 in the opposite direction and then resets. After vibration, the dust particles or debris on the top of the industrial filter cloth 206 fall to the position of the feed guide plate 205 and are finally discharged from the waste port 3.

[0049] The transmission unit 208 drives the fan impeller 209 to rotate, and the rotation of the fan impeller 209 causes the airflow inside the dust collection bin 201 to circulate. The external airflow is transported into the dust collection bin 201 through the position of the feeding grid 4. At this time, the dust particles and debris generated by the laser scanning gun 8 for laser rust removal of steel components enter the dust collection bin 201 with the airflow and are filtered by the industrial filter cloth 206.

[0050] The filtered airflow is output through the output end of the fan compartment 202 and delivered to the position of the first jet unit 6 through the air supply pipe 15. The first jet unit 6 cleans the two sides of the top of the rust removal platform 1, further improving the concentration effect of dust particles and debris.

[0051] Furthermore, airflow is delivered to the interior of the wind turbine housing 903 through the air supply branch pipe 13 and blows the wind turbine 904, causing the wind turbine 904 to rotate and drive the second drive shaft 907 to rotate. The rotation of the second drive shaft 907 drives the second incomplete gear 905 to rotate, which in turn causes the gear 910 meshing with the second incomplete gear 905 to drive the third drive shaft 909 to rotate. The rotation of the third drive shaft 909 causes the laser scanning gun 8 to rotate accordingly, and causes the torsion spring 902 to twist.

[0052] When the second incomplete gear 905 rotates and no longer meshes with the gear 910, the third transmission shaft 909 is driven by the reverse torsional force of the torsion spring 902 to rotate the laser scanning gun 8 in the opposite direction, thereby realizing the function of reciprocating oscillation of the laser scanning gun 8. This allows the laser scanning gun 8 to maintain a stable distance for focusing during the rust removal process of steel components, and also improves the rust removal effect.

[0053] The airflow output from the wind turbine 903 enters the second jet unit 17 and is ejected through the second jet unit 17. At this time, the airflow ejected by the second jet unit 17 blows the dust particles and debris generated by the laser scanning gun 8 into the interior of the feed grid 4, further improving the collection function of dust particles and debris during the rust removal process.

[0054] Meanwhile, during the reciprocating swing of the laser scanning gun 8, the laser scanning gun 8 drives the push rod 18 to generate a pushing force on the movable plate 14, causing the movable plate 14 to drive the second jet unit 17 to follow the displacement. The sliders 20 at both ends of the second jet unit 17 are displaced inside the support frame 16 and compress or stretch the first spring 19, so that the second jet unit 17 always maintains a safe distance from the output end of the laser scanning gun 8. While ensuring the stability of laser cutting, it also ensures the function of collecting smoke particles and debris, further improving the practicality of the device.

[0055] Through the cooperation of various components, the airflow generated by the fan impeller 209 is utilized to the maximum extent. The flow of this airflow enables the rust removal device to clean, remove dust, filter, and drive the laser scanning gun 8 to swing back and forth.

[0056] The specific implementation of this embodiment has been described above. However, this embodiment is not limited to the specific implementation described above. The specific implementation described above is merely illustrative and not restrictive. Those skilled in the art can make many other forms based on the guidance of this embodiment, all of which are within the protection scope of this embodiment.
