Description

Technical Field

[0001] The invention relates to the technical field of laser cutting, in particular to a visual three-dimensional five-axis carbon dioxide laser cutting machine. Background Art

[0002] As an important part of advanced manufacturing technology, laser technology is the core driving force of the visual 3D five-axis CO2 laser cutting machine. CO2 laser is an early mature industrial laser. With its high power output and relatively low cost, it occupies an important position in the field of cutting metal and non-metal materials. However, with the rapid development of fiber laser technology, its better beam quality, higher energy conversion efficiency and lower maintenance cost have gradually made it the first choice for high-precision cutting.

[0003] In the existing technology, the main function of the laser three-dimensional five-axis laser cutting machine is that when processing three-dimensional metal parts, the cutting head has a sensor function that can effectively control the cutting head at a specified distance from the workpiece to achieve effective cutting. However, the sensor function of the carbon dioxide three-dimensional five-axis cutting equipment is in a failed state when cutting non-metallic materials. If the workpiece is deformed greatly or the cutting point is deformed, the cut product will also be deformed. They generally use the teaching mode of the three-dimensional software to manually collect the points and then perform subsequent cutting. This not only increases the manual teaching time, but also reduces production efficiency and increases labor costs. Summary of the invention

The image that is visually recognized is fed back to the three-dimensional system.

[0017] 2. When the present invention is in use and the product is cut, firstly, with the cooperation of the first motor, gear, first slide rail and other structures, the movable frame and the mounting column can be driven to move, and the three-dimensional cutting head can be driven to move to a suitable position. At the same time, with the action of the second motor, transmission wheel, second rack and other structures, the movable plate can be driven to move, thereby driving the three-dimensional cutting head to a suitable position. And with the action of the third motor, the meshing wheel, the third slider and the third slide rail, the fixed plate and the long flight optical path integrated movable column can be driven up and down, and the three-dimensional cutting head can be driven to move to a suitable position. Through the above structure, the position of the three-dimensional cutting head can be adjusted, so that it can be suitable for more products, which greatly improves the practicability of the laser cutting machine.

[0018] 3. When the present invention is in use, when the laser cutting machine is cutting a product, the three-dimensional cutting head is always moving.

[0032] In this embodiment, when using the visual three-dimensional five-axis carbon dioxide laser cutting machine to cut the product, it is necessary to adjust its three-dimensional cutting head 35 to a suitable position. First, under the action of the first motor 10, the gear 11 is driven to rotate. At the same time, under the cooperation of the first rack 7, the first slider 6 can be moved on the outer wall of the first slide rail 5, thereby driving the movable frame 8 and the mounting column 13 to move, and driving the three-dimensional cutting head 35 to move horizontally to a suitable position. Subsequently, under the action of the second motor 21, the transmission wheel 22 is driven to rotate. At the same time, under the action of the second rack 15, the second slider 17 is driven to move on the outer wall of the second slide rail 16, and the movable plate 1 8 and the fixed frame 23 move, thereby driving the three-dimensional cutting head 35 to move horizontally and longitudinally to a suitable position, and then, under the action of the third motor 25, the meshing wheel 26 is driven to rotate, and under the action of the third rack 30, the third slide rail 28 is driven to move inside the third slider 27, and at the same time, the fixed plate 29 and the long flight optical path integrated movable column 31 are driven to move, thereby driving the three-dimensional cutting head 35 to move vertically to a suitable position, and then the three-dimensional cutting head 35 can be used to cut the product. During the cutting process, the three-dimensional cutting head 35 can be driven to move again by the above-mentioned structure and method, thereby realizing the cutting of the product, which greatly improves the practicability of the cutting device.

[0033] Embodiment 3, according to Figure 1 , Figure 2 , Figure 4 as well as Figure 6 As shown, an outer wall of the mounting frame 1 is fixedly mounted with an outer shell 2, one side of the outer wall of the outer shell 2 is fixedly mounted with a support column 3, an outer wall of the support column 3 is fixedly mounted with a control console 4, two first dust covers 12 are arranged on the top of the mounting frame 1, and one side of the outer wall of the first dust cover 12 is fixedly connected to one side of the outer wall of the movable frame 8, a second dust cover 14 is arranged on the top of the mounting column 13, and one side of the outer wall of the second dust cover 14 is fixedly connected to one side of the outer wall of the movable plate 18, and a protective shell 19 is fixedly mounted on the top of the movable plate 18.

[0034] In this embodiment, when using laser cutting to cut the product, it is necessary to drive the three-dimensional cutting head 35 to move continuously to achieve cutting of the product. When the three-dimensional cutting head 35 is driven to move by the mobile structure, the mobile structure can be protected by the first dust cover 12, the second dust cover 14 and the protective shell 19 to prevent the mobile structure from being exposed to the outside for a long time and being affected by other dust and impurities and being unable to be used, thereby extending its service life.

[0035] The working principle of the whole mechanism is as follows: when using the visual three-dimensional five-axis carbon dioxide laser cutting machine to cut the product, it is necessary to adjust the three-dimensional cutting head 35 to a suitable position. First, under the action of the first motor 10, the gear 11 is driven to rotate. At the same time, with the cooperation of the first rack 7, the first slider 6 can be moved on the outer wall of the first slide rail 5, thereby driving the movable frame 8 and the mounting column 13 to move, and driving the three-dimensional cutting head 35 to move horizontally to a suitable position. Then, under the action of the second motor 21, the transmission wheel 22 is driven to rotate. At the same time, under the action of the second rack 15, the second slider 17 is driven to move on the outer wall of the second slide rail 16, and the movable plate 18 and the fixed frame 23 are driven to move, thereby driving the three-dimensional cutting head 35 to move horizontally and longitudinally to a suitable position.

At the same time, with the cooperation of the first micro motor 32 and the second micro motor 34, the angle of the three-dimensional cutting head 35 can be further adjusted. Subsequently, with the cooperation of the industrial camera 37 and the light source 38, multiple original points of the product can be collected and photographed, and the visually photographed and recognized images can be fed back to the three-dimensional system. The three-dimensional system can completely compensate for the problems of micro-deformation and large-scale deformation of the original points of the cutting workpiece. The visual system mainly corrects the offset of the deformation to achieve effective cutting requirements. With the visual three-dimensional five-axis system, there is no need to manually collect the original point information of the workpiece in the teaching mode. Through the CAM nesting software of the equipment, we can directly collect the starting point position of the cutting at one time through the program, which greatly saves the manual teaching time. At the same time, our CAM nesting software and the visual three-dimensional five-axis system are integrated software. The visual three-dimensional five-axis carbon dioxide laser cutting machine brings more efficiency and safety to the non-metallic industry. Then, with the cooperation of the first micro motor 32, the second micro motor 34 and the mobile structure, the three-dimensional cutting head 35 is driven to move, thereby completing the cutting of the product.
