Description

Technical Field

[0001] This utility model relates to the field of smoke absorption technology, and in particular to a smoke absorption device for laser marking. Background Technology

[0002] Laser marking is a method of marking the surface of an object using laser technology. Laser marking uses a pulsed laser to output a controlled high-frequency pulsed laser, which is transmitted through an optical fiber and focused on the surface of the object being processed. The instantaneous high temperature melts or vaporizes the material being processed, thereby forming a permanent mark on the surface of the object.

[0003] During laser marking operations, the materials inevitably generate a large amount of smoke when burned by the laser. In existing technologies, most smoke absorption devices cannot flexibly adjust the position of the dust collection device, making it difficult to perfectly adapt to different marking scenarios. This results in some smoke not being effectively collected, reducing the working efficiency of the smoke absorption device. For example, when marking large and complex workpieces, the fixed position of the dust collection device prevents it from getting close to the smoke source, causing a large amount of smoke to escape into the working environment, affecting the health of the operators and making it impractical. Therefore, it is necessary to redesign a smoke absorption device for laser marking to address the above problems. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a smoke absorption device for laser marking.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A smoke absorption device for laser marking includes a worktable. Two support legs are fixedly installed on the bottom wall of the worktable. Movable grooves are formed on both outer walls of the worktable. Slider blocks are slidably installed inside each of the two movable grooves via a sliding mechanism. A support frame is fixedly installed on the upper surface of both sliders. A toothed plate is fixedly installed on the bottom wall of one slider via a connecting mechanism. A first motor is fixedly installed on the bottom wall of the worktable via the support mechanism. A gear is fixedly installed on the outer wall of the output shaft of the first motor, and the gear meshes with the toothed plate. A fan is fixedly installed on the upper surface of the support frame. A dust collection hood is fixedly installed on the outer wall of the fan inlet pipe, a collection box is fixedly installed on the outer wall of the fan outlet pipe, a filter plate is fixedly installed on the outer wall of the dust collection hood, and fixed plates are fixedly installed on both outer walls of the dust collection hood. A reciprocating screw is rotatably installed between the two fixed plates. A second motor connected to the reciprocating screw is fixedly installed on the outer wall of one of the fixed plates. A screw sleeve is threadedly installed on the outer wall of the reciprocating screw through a limiting mechanism. A cleaning brush is fixedly installed on the outer wall of the screw sleeve. An installation plate is fixedly installed on the upper surface of the workbench, and a marking device is fixedly installed on the inner wall of the installation plate through a lifting mechanism.

[0007] Preferably, the sliding mechanism includes a slide rod fixedly installed inside the moving groove, and the slider is slidably installed on the outer wall of the slide rod.

[0008] Preferably, the connecting mechanism includes a connecting rod fixedly installed on the bottom wall of the slider, and the end of the connecting rod is fixedly connected to the outer wall of the toothed plate.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0023] Reference Figure 1-6A smoke absorption device for laser marking includes a worktable 1. Two support legs 2 are fixedly installed on the bottom wall of the worktable 1. Movable grooves are opened on both outer walls of the worktable 1. Slider 4 is slidably installed in the two movable grooves through a sliding mechanism. The sliding mechanism includes a slide rod 3 fixedly installed inside the movable groove. The slider 4 is slidably installed on the outer wall of the slide rod 3. A support frame 5 is fixedly installed on the upper surface of the two sliders 4. A toothed plate 7 is fixedly installed on the bottom wall of one of the sliders 4 through a connecting mechanism. The connecting mechanism includes a connecting rod 6 fixedly installed on the bottom wall of the slider 4. The end of the connecting rod 6 is fixedly connected to the outer wall of the toothed plate 7. A first motor 9 is fixedly installed on the bottom wall of the worktable 1 through a support mechanism. The support mechanism includes a support plate 8 fixedly installed on the bottom wall of the worktable 1. The first motor 9 is fixedly installed on the outer wall of the support plate 8. A gear 10 is fixedly installed on the outer wall of the output shaft of the first motor 9. The gear 10 meshes with the toothed plate 7.

[0024] A fan 11 is fixedly installed on the upper surface of the support frame 5. A dust collection hood 12 is fixedly installed on the outer wall of the inlet pipe of the fan 11, and a collection box 13 is fixedly installed on the outer wall of the outlet pipe of the fan 11. A filter plate 14 is fixedly installed on the outer wall of the dust collection hood 12. Fixing plates 15 are fixedly installed on both outer walls of the dust collection hood 12. A reciprocating screw 16 is rotatably installed between the two fixing plates 15. A second motor 17 connected to the reciprocating screw 16 is fixedly installed on the outer wall of one of the fixing plates 15. A screw sleeve 19 is threadedly installed on the outer wall of the reciprocating screw 16 through a limiting mechanism. The limiting mechanism includes a fixing... A limiting rod 18 is installed between two fixed plates 15. The limiting rod 18 slides through the lead screw sleeve 19 and can limit the lead screw sleeve 19 so that the lead screw sleeve 19 can only move axially along the outer wall of the reciprocating lead screw 16. A cleaning brush 20 is fixedly installed on the outer wall of the lead screw sleeve 19. An installation plate 21 is fixedly installed on the upper surface of the worktable 1. A marking device 23 is fixedly installed on the inner wall of the installation plate 21 through a lifting mechanism. The lifting mechanism includes a cylinder 22 fixedly installed on the inner wall of the installation plate 21. The telescopic end of the cylinder 22 is fixedly connected to the upper surface of the marking device 23.

[0025] When this utility model is in use, when laser marking is required, the cylinder 22 on the inner wall of the mounting plate 21 on the upper surface of the workbench 1 starts to work. The telescopic end of the cylinder 22 drives the marking device 23 to move up and down. According to the height of the workpiece to be marked and the marking requirements, the marking device 23 is adjusted to a suitable height position. This design allows the marking device 23 to adapt to workpieces of different heights, providing a guarantee for accurate marking. During the marking process, in order to enable the dust collection device to better collect smoke, the first motor 9 can drive the gear 10 of its output shaft to rotate. Since the gear 10 and the toothed plate 7 fixed to the bottom wall of the slider 4 by the connecting rod 6 mesh with each other, the rotation of the gear 10 will drive the toothed plate 7 to move linearly. The slider 4 slides on the slide rod 3 in the moving groove and moves synchronously with the toothed plate 7, so that the two sliders 4 together drive the support frame 5 to move horizontally along the moving grooves on both sides of the workbench 1. This can drive the fan 11 and the dust collection hood 12 to move horizontally. Thus, the horizontal position of the dust collection hood 12 can be flexibly adjusted according to the marking position, so that it is closer to the smoke source and the smoke collection efficiency is improved.

[0026] After the dust hood 12 is positioned correctly, the fan 11 operates to generate suction, drawing in the fumes produced during laser marking. Before entering the fan 11, the fumes pass through the filter screen 14 on the outer wall of the dust hood 12. The filter screen 14 filters out large particles in the fumes, preventing them from entering the fan 11 and collection box 13 and damaging the equipment. The fumes filtered by the filter screen 14 enter the collection box 13 through the outlet pipe of the fan 11, where they undergo further processing and collection. As the process continues, dust and impurities will gradually accumulate on the filter plate 14, affecting its filtration effect. In order to ensure the normal operation of the filter plate 14, the second motor 17 drives the reciprocating screw 16 to rotate. The reciprocating screw 16 can drive the screw sleeve 19 to move through cooperation with the limit rod 18. When the screw sleeve 19 moves, it can drive the cleaning brush 20 fixedly installed on the outer wall to reciprocate, clean the surface of the filter plate 14, brush off the accumulated dust and impurities, ensure the permeability of the filter plate 14, and thus maintain the efficient operation of the entire smoke absorption device.

[0027] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
