Description

Technical Field

[0001] The embodiments of the present invention relate to the technical field of laser processing components, and in particular to an automatic focusing laser processing component capable of automatically replacing processing parts. Background Art

[0002] Laser processing is the most commonly used application of laser systems. According to the mechanism of interaction between laser beam and material, laser processing can be roughly divided into two categories: laser thermal processing and photochemical reaction processing. Laser thermal processing refers to the use of the thermal effect generated by projecting a laser beam onto the surface of a material to complete the processing process, including laser welding, laser engraving and cutting, surface modification, laser laser marking, laser drilling and micromachining, etc.; photochemical reaction processing refers to the process of irradiating a laser beam onto an object and initiating or controlling a photochemical reaction with the help of high-density laser high-energy photons. It includes photochemical deposition, stereolithography, laser engraving and etching. Automatic focus laser processing refers to the ability to adjust the position of the laser in order to locate the processing position.

[0003] Laser processing is to use the energy of light to reach a high energy density at the focal point after being focused by a lens, and to process by photothermal effect. Laser processing does not require tools, has a fast processing speed, and has small surface deformation, and can process various materials. Use laser beams to perform various processing on materials, such as drilling, cutting, scribing, welding, heat treatment, etc. Some substances with metastable energy levels will absorb light energy under the stimulation of external photons, so that the number of atoms in high energy levels is greater than the number of atoms in low energy levels - the number of particles is inverted. If a beam of light is irradiated, the energy of the photon is equal to the corresponding difference between the two energies, and stimulated radiation will be generated at this time, outputting a large amount of light energy. Compared with traditional processing technology, laser processing technology has the advantages of less material waste, obvious cost effect in large-scale production, and strong adaptability to the processing object. Laser processing is a non-contact processing, and the energy and moving speed of the high-energy laser beam can be adjusted, so it can achieve a variety of processing purposes. It can process a variety of metals and non-metals, especially materials with high hardness, high brittleness and high melting point. Laser processing is highly flexible and is mainly used for cutting, surface treatment, welding, marking and drilling, etc. Laser surface treatment includes laser phase change hardening, laser cladding, laser surface alloying and laser surface melting.

[0005] To this end, an embodiment of the present invention provides an automatic focus-finding laser processing component that can automatically replace workpieces.

At this time, the next workpiece moves to the top of the workbench for processing under the elastic force of the spring, thereby realizing automatic replacement of workpieces and effectively improving processing efficiency, so as to solve the problem in the prior art that for the same batch of workpieces, manual replacement of workpieces is still required during laser processing, resulting in low processing efficiency.

[0050] Working principle:

[0051] Refer to the instruction manual Figure 1-7:The laser beam emitted by the laser 9 can be reflected by the reflector 14, so that the laser beam is irradiated into the positioning hole 32 of the positioning plate 17. If the position of the laser beam is offset, the first electric push rod 10 is started, and the first electric push rod 10 drives the laser 9 to move, thereby driving the rack 12 to move through the connecting rod 11. The rack 12 drives the gear 16 meshing with it to rotate, thereby causing the rotating rod 15 connected to the bearing of the vertical plate 2 to rotate. The rotation of the rotating rod 15 simultaneously drives the mirror frame 13 and the reflector 14 to rotate, thereby adjusting the angle of the reflector 14, thereby adjusting the position of the laser beam so that the laser beam is irradiated into the positioning hole 32 of the positioning plate 17, and realizing the automatic focus function;

[0052] Refer to the instruction manual Figure 1-10 : Open the door panel 39, press the support plate 20 downward to compress the spring 21, then put a workpiece on the support plate 20, so that the inner rod 19 is aligned with the processing position of the workpiece, and then move the four limit plates 23 in the horizontal direction to limit the workpiece, and then tighten the first fastening bolt 35 on the T-shaped slider 34 to fix the limit plate 23, and then stack a batch of workpieces on the first workpiece in turn. At this time, the processing positions of multiple workpieces are directly below the inner rod 19 and the positioning hole 32, that is, directly below the laser beam, and then remove the positioning plate 17, the hollow rod 18 and the inner rod 19, and then Move the baffle 26 to both sides just above the workpiece, and the workpiece and the support plate 20 move upward under the elastic force of the spring 21, so that the workpiece moves to the top of the workbench 1 and is at the bottom of the baffle 26, and then the first workpiece is processed by the laser 9. After the processing is completed, start the second electric push rod 27 to drive the push plate 28 to move, thereby pushing the first workpiece to move, and then the second electric push rod 27 contracts to drive the push plate 28 to return to its original position. At this time, the next workpiece moves to the top of the workbench 1 under the elastic force of the spring 21, and is processed again with the above operation, thereby realizing automatic replacement of the workpiece.
