Description
Technical Field
[0001] The utility model belongs to the technical field of laser processing equipment, and in particular relates to a single laser light source cutting and scanning device. Background Art
[0002] In the field of laser application, both R&D and production enterprises will have the demand for two different processing modes: laser cutting and laser scanning. In the past, enterprises could only purchase two types of machines, and the main cost of existing laser equipment is concentrated on the laser generator, which can only cut the workpiece alone and cannot scan the workpiece on the laser equipment. Therefore, the workpiece needs to be switched alternately between the laser cutting equipment and the laser scanning equipment, which will slow down the progress of the laser cutting and laser scanning of the workpiece. In addition, the dual application mode of a single light source needs to ensure the safety and stability of the switching process under the premise of realizing the dual application mode. Utility Model Content
[0003] The purpose of the utility model is to provide a single laser light source cutting and scanning device to solve the problems raised in the above background technology.
[0004] To achieve the above purpose, the utility model provides the following technical solution: a single laser light source cutting and scanning device, comprising:
[0005] A laser generator, wherein a reflector A for right-angle reflection of laser light is provided at the front end of the laser reflector head of the laser generator, a beam processing box for optimizing the quality of the laser beam is provided in the straight line direction of the laser beam reflected by the reflector A, and a reflector B for right-angle reflection of the laser beam is provided at one end of the beam processing box emitting the laser beam;
[0006] A galvanometer, wherein a field lens for focusing the reflected laser beam onto the cutting workpiece surface is provided at the vertical bottom direction of the galvanometer, and an optical path switching power assembly for changing the direction of the laser beam reflected at right angles to the reflector B is provided at the front end of the galvanometer, and a laser cutting head for cutting the workpiece by reflecting the laser beam is provided at the lower end of the optical path switching power assembly.
[0007] Preferably, the optical path switching power assembly includes a vertical guide plate, and a reflector C, a reflector D, and a reflector E. A disposal adjustment slide is provided on one side of the guide plate for vertical sliding. The reflector C and the reflector D are arranged vertically on the corresponding front side of the guide plate, and the reflector E is arranged at a position of the laser beam reflection output direction of the reflector D. The laser cutting head is a working unit. If the adjustment slide drives the reflector E to move downward, the optical path directly enters the galvanometer. At this time, the scanning assembly is a working unit.
[0008] Preferably, the reflector E is mounted on an adjustment slide that slides on the guide plate to switch the laser beam optical path up and down. The adjustment slide drives the reflector to move up, and the light passes through the reflector E to enter the laser cutting head. At this time, the laser cutting head is a working unit. If the optical path switching power assembly drives the reflector E to move down, the laser beam directly enters the galvanometer.
[0009] Preferably, the optical path switching power assembly includes a transverse guide plate, and a reflector C and a reflector D. The guide plate has an adjustable slide seat that slides transversely on one side corresponding to the galvanometer. The reflector C is arranged at the vertical upper end of the reflector D to reflect the laser beam vertically downward, thereby realizing the switching of the scanning working state of the workpiece and improving the work efficiency of the workpiece cutting scanning.
[0010] Preferably, the reflector D is mounted on an adjustment slide that slides on the guide plate and is used to change the direction of the laser beam reflected by the reflector C, thereby realizing forward and backward movement of the reflector to switch the working state of the laser beam.
[0011] Preferably, one side of the guide rail plate is symmetrically provided with guide slide rods on the inner side of fixed blocks provided at both ends, and the adjustment slide seat passes through the guide slide rods to be moved and adjusted on the guide rail plate, so that the laser beam can switch the cutting and scanning working state by moving the reflector up and down and forward and backward.
[0012] Compared with the prior art, the technical effects and advantages of the utility model are as follows: the single laser light source cutting and scanning equipment, after the laser generator emits light, the light speed quality adjustment is performed first, and then the split light path has the following two types:
[0013] 1. The optical path used is the galvanometer optical path. After the laser beam comes out of the laser generator, it passes through the reflector A and enters the beam processing box for beam processing, and then passes through the reflector B, reflector C, and reflector D in sequence. At this time, if the optical path switching power component drives the reflector E to move up, the light path passes through the reflector E and enters the laser cutting head. At this time, the laser cutting head cuts the workpiece as a working unit. If the optical path switching power component drives the reflector E to move down, the light path directly enters the galvanometer. At this time, the galvanometer scans the workpiece as a working unit, and the cutting scanning mode of the workpiece can be switched on the cutting equipment, which further improves the efficiency of workpiece manufacturing and reduces the equipment's research and development and use costs.
[0014] 2. The fixed optical path is the laser cutting head optical path. After the laser beam comes out of the laser generator, it passes through the reflector A beam processing box for beam processing, and then passes through the reflector B and reflector C in turn. At this time, if the optical path switching power component drives the reflector D to move forward, the optical path is directly reflected into the laser cutting head. At this time, the laser cutting head cuts the workpiece as a working unit. If the optical path switching power component drives the reflector D to move backward, the optical path is reflected by the reflector D into the galvanometer. At this time, the galvanometer scans the workpiece as a working unit, thereby realizing the cutting and scanning of the workpiece in the cutting equipment, reducing the number of equipment used and the floor space occupied, and ensuring the safety and stability of the single laser beam during the switching process.

Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0019] See also Figure 1-2 The utility model provides a technical solution: a single laser light source cutting and scanning device, comprising:
[0020] A laser generator 1, wherein a reflector A2 for right-angle reflection of the laser is provided at the front end of the laser reflection head of the laser generator 1, so that the laser beam passes through the reflector A2 and enters the interior of the beam processing box 3 for beam optimization processing. A beam processing box 3 for optimizing the quality of the laser beam is provided in the straight direction of the laser beam reflected by the reflector A2, which can shape and adjust the light beam output by the laser generator 1 to improve the quality and stability of the light beam, and can also adjust the cross section of the light beam, such as reducing the defocus of the light beam, improving the uniformity of the light spot, etc., so as to improve the focusing ability and processing quality of the laser beam. A reflector B4 for right-angle reflection of the laser beam is provided at one end of the light beam processing box 3 that emits the laser beam, and the reflector B4 can reflect the laser beam after the optimization processing by the light beam processing box 3 and transmit it to the reflector C10, so as to effectively switch the cutting and scanning modes of the laser beam;
[0021] The galvanometer 5 is provided with a field lens 6 at the vertical bottom end direction for focusing the reflected laser beam onto the cutting workpiece surface, which can control the focal size and shape of the laser beam on the workpiece surface to meet different processing requirements, and can realize high-temperature and high-energy local heating, thereby realizing fast and precise cutting or processing, and can maximize the use of the output power of the laser generator 1 and focus it on a small area on the workpiece surface, which can improve the cutting efficiency and processing speed and reduce energy waste, and the front end of the galvanometer 5 is provided with an optical path switching power assembly 7 for changing the direction of the laser beam reflected at right angles by the reflector B4, which is used to switch the laser beam working mode, and can realize cutting and scanning of the workpiece on the device, and the lower end of the optical path switching power assembly 7 is provided with a laser cutting head 8 for cutting the workpiece by reflecting the laser beam, which can cut the workpiece through the laser beam reflected into the laser cutting head 8.
[0022] The optical path switching power assembly 7 includes a vertical guide plate 9, and a reflector C10, a reflector D11, and a reflector E12. A vertically sliding adjustment slide 13 is provided on one side of the guide plate 9, so that the position of the reflector E12 can be adjusted using the adjustment slide 13 to facilitate the switching of the laser beam working mode, thereby making the device more convenient in the process of switching the working state. The reflector C10 and the reflector D11 are vertically arranged on the corresponding front side of the guide plate 9, and can reflect the reflected laser beam to the laser cutting head 8 and the galvanometer 5 to cut and scan the workpiece, and the reflector E12 is set at the position of the laser beam reflection output direction of the reflector D11. The reflector E12 is installed on the adjustment slide 13 sliding on the guide plate 9 to switch the laser beam optical path up and down (such as Figure 1 shown).
[0023] The optical path switching power assembly 7 includes a transverse guide plate 9, a reflector C10 and a reflector D11. The guide plate 9 has an adjustment slide 13 that slides transversely on one side corresponding to the galvanometer 5, and the position of the reflector D11 can be adjusted transversely to change the mode of laser beam processing on the workpiece. The reflector C10 is arranged at the vertical upper end of the reflector D11 to reflect the laser beam vertically downward, and the reflected laser beam is reflected to the reflector D11 to switch the laser beam cutting and scanning working modes. The reflector D11 is installed on the adjustment slide 13 that slides on the guide plate 9 to change the direction of the laser beam reflected by the reflector C10. One side of the guide plate 9 is symmetrically provided with guide slide rods 14 on the inner side of the fixed blocks arranged at both ends, and the adjustment slide 13 passes through the guide slide rod 14 to move and adjust on the guide plate 9 (such as Figure 2 shown).
[0024] Specifically, when using Figure 1 As shown, the optical path used in the equipment is the optical path of the galvanometer 5. After the laser beam comes out of the laser generator 1, the output laser beam is directly projected onto the reflector A2. The laser beam in the reflector A2 is reflected at a right angle and enters the beam processing box 3 for laser beam optimization to obtain a laser beam with better quality. Then, the laser beam is output from the other end of the beam processing box 3 and directly projected onto the reflector B4. The laser beam in the reflector B4 is reflected onto the reflector C10. The laser beam passing through the reflector C10 is reflected onto the reflector D11. At this time, if the adjustment slide 13 slides on the guide plate 9 to drive the reflector E12 to slide upward, the laser beam is reflected into the reflector E12 and directly reflected into the laser cutting head 8. At this time, the laser cutting head 8 is a working unit to cut the surface of the workpiece. If the adjustment slide 13 slides on the guide plate 9 to drive the reflector E12 to move downward, the laser beam directly enters the galvanometer 5. At this time, the galvanometer 5 is a working unit to scan the workpiece.
[0025] like Figure 2The optical path used in the equipment shown is the optical path of the laser cutting head 8. After the laser beam comes out of the laser generator 1, the output laser beam is directly projected on the reflector A2. The laser beam in the reflector A2 is reflected at a right angle and enters the beam processing box 3 for laser beam optimization to obtain a laser beam with better quality. Then the laser beam is output from the other end of the beam processing box 3 and directly projected on the reflector B4. The laser beam in the reflector B4 is reflected to the reflector C10, and the laser beam passing through the reflector C10 is reflected to the reflector D11. At this time, if the adjustment slide 13 slides on the guide plate 9 to drive the reflector D11 to slide forward, the laser beam directly enters the laser cutting head 8. At this time, the laser cutting head 8 is a working unit to cut the workpiece. If the adjustment slide 13 slides on the guide plate 9 to drive the reflector D11 to move backward, the laser beam passes through the reflector D11 and enters the galvanometer 5. At this time, the galvanometer 5 is a working unit to scan the workpiece.
