Description

Technical Field

[0001] The utility model relates to the field of laser cutting, in particular to an automated laser cutting machine. Background Art

[0002] A laser cutting machine emits laser from a laser, which is focused into a laser beam with a high power density through an optical path system. The laser beam irradiates the surface of a workpiece, causing the workpiece to reach the melting point or boiling point. At the same time, a high-pressure gas coaxial with the beam blows away the melted or vaporized metal. As the relative position of the beam and the workpiece moves, finally a cut is formed in the material, so as to achieve the purpose of cutting. Laser cutting uses an invisible beam to replace the traditional mechanical knife, with the characteristics of high precision, fast cutting, not limited by the cutting pattern, automatic layout to save materials, smooth cut, low processing cost, etc. The mechanical part of the laser cutter head has no contact with the workpiece and will not scratch the surface of the workpiece during work.

[0003] During the cutting process of the existing laser cutting machine, larger cutting parts are easy to be clamped. The cutting accuracy requirement is not high, and the cutting process requirements can be met directly by laser cutting. The large plates after cutting are directly transported by external mechanical equipment; while smaller or thinner cutting parts have high cutting accuracy requirements, are not easy to be clamped, and the dust on the workpiece will cause errors during laser cutting, reducing the finished product quality.

Detailed implementation manners

[0020] To more clearly illustrate the purpose, technical solutions and advantages of the embodiments of the present invention, the present invention will be further described below in conjunction with the accompanying drawings and embodiments. A clear and complete description is made. Obviously, the described embodiments are partial embodiments of the present invention, rather than all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the protection scope of the present invention. In addition, the directional terms mentioned in the present invention, for example, "up", "down", "front", "rear", "left", "right", "inside", "outside", etc., are only references to the directions in the attached drawings. The directional terms used are for better and clearer illustration and understanding of the present invention, rather than indicating or implying the orientation that the present invention must have. Therefore, it cannot be understood as a limitation to the present invention.

[0021] Embodiments of the present invention are as follows Figures 1 to 3As shown in the figure, an automated laser cutting machine includes a frame 1. The frame 1 has a hollow cubic structure. Four adjustable feet are correspondingly installed at the four top corners of the bottom of the frame 1. The level of the frame 1 can be adjusted by using the adjustable feet. Two first linear guides 2 are horizontally arranged in parallel on the opposite sides of the top of the frame 1. The two first linear guides 2 use the same linear guide. That is, one first linear guide 2 is arranged in the front-back direction on the left side of the top of the frame 1, and the other first linear guide 2 is arranged in the front-back direction on the right side of the top of the frame 1. The two first linear guides 2 are both driven by cylinders. They are arranged on the top of the frame 1, which means that the two first linear guides 2 are both at a certain height above the top of the frame 1. The installation of the two first linear guides 2 on the frame 1 is that two mounting brackets 20 with the same height are horizontally arranged in parallel on the opposite sides of the top of the frame 1. The two first linear guides 2 are correspondingly arranged on the tops of the two mounting brackets 20. For example, a mounting bracket 20 with an n-shaped structure in the front-back direction is arranged on the left side of the top of the frame 1. The two feet of the mounting bracket 20 are correspondingly located at the front and rear ends on the left side of the top of the frame 1. Similarly, a mounting bracket 20 of the same kind can be arranged on the right side of the top of the frame 1. The two mounting brackets 20 have the same height. After the two first linear guides 2 are installed on the mounting brackets 20, they are at the same height, ensuring that the laser cutting mechanism 4 can be horizontal. The two ends of a second linear guide 3 are correspondingly slidably arranged on the two first linear guides 2. The second linear guide 3 is a linear guide driven by a cylinder in the left-right direction. It can slide in the front-back direction on the two first linear guides 2. The two ends of the second linear guide 3 are correspondingly connected to the sliders of the two first linear guides 2. A laser cutting mechanism 4 is slidably arranged on the second linear guide 3. The laser cutting mechanism 4 can adjust its position in the front-back direction by moving back and forth on the two first linear guides 2 along with the second linear guide 3. At the same time, the laser cutting mechanism 4 can also slide left and right independently on the second linear guide 3 to adjust its position in the left-right direction; One side of the laser cutting mechanism 4 is provided with an image acquisition mechanism 5 that can move synchronously with it. On the one hand, the image acquisition mechanism 5 detects the relative position between the laser cutting mechanism 4 and the product to be cut before cutting, and then adjusts it through the control of the industrial computer. On the other hand, the image acquisition mechanism 5 can also detect the cutting effect after cutting is completed, and can also monitor the cutting process in real time through the image acquisition mechanism 5 during the cutting process to ensure the cutting accuracy and quality. At this time, the image acquisition mechanism 5 is an industrial camera, and a telecentric lens 50 is arranged on the image acquisition mechanism 5. The telecentric lens 50 can correct the parallax of the traditional industrial camera and provide a more accurate image. At the same time, in order to facilitate the image acquisition mechanism 5 to have a good lighting environment when acquiring images, a lighting device 9 is arranged at a position adjacent to the image acquisition mechanism 5 on one side of the laser cutting mechanism 4. The lighting device 9 uses an LED fill light;A blowing mechanism 6 with an annular structure is arranged directly below the laser cutting mechanism 4 and can move synchronously with it. The blowing mechanism 6 is located above the adsorption platform 8. By using the blowing mechanism 6, it is very convenient to blow away the dust or other impurities on the product. Setting the blowing mechanism 6 into an annular structure enables it to surround the product to be cut for one week, and can blow away the dust or impurities on the product to be cut in all directions. A third linear guide rail 7 parallel to the first linear guide rails 2 is also arranged on the frame 1 between the two first linear guide rails 2 and below the second linear guide rail 3. The third linear guide rail 7 is driven by a motor or a cylinder. An adsorption platform 8 for adsorbing the product to be cut is slidably arranged on the third linear guide rail 7. That is to say, the third linear guide rail 7 is also in the front-back direction and is arranged between the two first linear guide rails 2. At this time, the two first linear guide rails 2 are above the top surface of the adsorption platform 8, and there is a certain distance between them and the top surface of the adsorption platform 8, which facilitates the setting and movement of the laser cutting mechanism 4, the image acquisition mechanism 5 and the blowing mechanism 6.

[0022] Further improvement, such as Figure 1 and Figure 2 As shown in, the laser cutting mechanism 4 includes a mounting seat 40 slidably arranged on the second linear guide rail 3, a laser 41 arranged on the mounting seat 40, and a laser head 42 connected to the laser 41. The image acquisition mechanism 5 is arranged on the mounting seat 40 adjacent to the laser head 42. A connecting piece 43 extending downward is connected to the mounting seat 40, and the blowing mechanism 6 is connected to the bottom of the connecting piece 43. That is to say, the laser 41, the image acquisition mechanism 5 and the blowing mechanism 6 are all mounted on the mounting seat 40. The mounting seat 40 acts as a slider on the second linear guide rail 3, facilitating their left-right sliding on the second linear guide rail 3. Here, the blowing mechanism 6 is connected to the mounting seat 40 through the connecting piece 43, so that the blowing of the blowing mechanism 6 will not affect other components.

[0023] Further improvement, such as Figure 1 and Figure 3 As shown in, the adsorption platform 8 is a vacuum negative pressure adsorption platform. A base 80 is installed at the bottom of the adsorption platform 8. The base 80 is slidably arranged on the third linear guide rail 7, which will not complicate the structure of the vacuum adsorption platform and facilitates the installation and sliding of the adsorption platform 8 on the third linear guide rail 7. The driving mechanism for driving the third linear guide rail 7 can also be installed on the base 80 to make the structure more compact.

[0024] Further improvement, such as Figure 1As shown, two adsorption platforms 8 are arranged side by side. Both adsorption platforms 8 are slidably arranged on the third linear guide rail 7. After adjusting the relative position in the front-rear direction between the adsorption platform 8 and the laser cutting mechanism 4, then by moving the laser cutting mechanism 4 left and right on the second linear guide rail 3, the products to be cut on the two adsorption platforms 8 can be processed in sequence. The positions of the two adsorption platforms 8 in the front-rear direction are adjusted in place at one time, without the need to adjust them separately, reducing the adjustment procedures and improving the production efficiency. At this time, in order to maintain the stability of the two adsorption platforms 8 on the third linear guide rail 7, a guiding rail 70 is arranged on both sides of the third linear guide rail 7 on the frame 1. The guiding rail 70 is parallel to the third linear guide rail 7 and is also in the front-rear direction. One side of the two adjacent adsorption platforms 8 is slidably arranged on the third linear guide rail 7, and the mutually remote sides of the two adsorption platforms 8 are correspondingly slidably arranged on the two guiding rails 70. One guiding rail 70 is located on the left side of the third linear guide rail 7, and the other guiding rail 7 is located on the right side of the third linear guide rail 7. The left bottom surface of the left adsorption platform 8 is slidably arranged on the left guiding rail 70, and the right bottom surface of the left adsorption platform 8 is connected to the left top surface of the slider of the third linear guide rail 7. Similarly, the right bottom surface of the right adsorption platform 8 is slidably arranged on the right guiding rail 70, and the left bottom surface of the right adsorption platform 8 is connected to the right top surface of the slider of the third linear guide rail 7. The sliding between the adsorption platform 8 and the guiding slide rail 70 is achieved by providing matching sliding protrusions and sliding grooves therebetween.

[0025] A further improvement is as Figure 1 and Figure 2 As shown, the blowing mechanism 6 includes an annular seat 60 with a square annular structure and a hollow interior, and an air supply joint 61 arranged on the annular seat 60. An air outlet is arranged at the bottom of the annular seat 60. The external air blower is connected through the air supply joint 61, and then the air is sent into the interior of the annular seat 60, and then the air is blown onto the product to be cut on the adsorption platform 8 through the air outlet on the annular seat 60.

[0026] Although the present invention has been described in detail above with general descriptions and specific embodiments, based on the present invention, some modifications or improvements can be made, which are obvious to those skilled in the art. Therefore, these modifications or improvements made without departing from the spirit of the present invention all fall within the scope of protection required by the present invention.
