[0002] A laser cutting machine is mainly a laser processing machine tool used to cut a plate into workpieces of required shapes, and is also a device that uses the thermal energy of a laser beam to achieve cutting. Laser cutting refers to using the energy released when a laser beam irradiates the surface of a workpiece to melt and evaporate the workpiece to achieve the purpose of cutting and engraving. It uses a laser beam emitted from a cutting guide rail, which is focused by an optical path system into a laser beam with a high power density for irradiation. The laser heat is absorbed by the workpiece material, the temperature of the workpiece rises rapidly, and after reaching the boiling point, the material begins to vaporize and form holes. Along with the high-pressure air flow, as the relative position of the beam and the workpiece moves, finally a cut is formed in the material.

[0013] Compared with the prior art, the beneficial effects of the present utility model are:

[0014] 1. Through the design of the first linear module, CCD camera, second linear module, laser cutting machine and feeding mechanism, when the staff place the metal profile on the upper surface of the feeding mechanism, the CCD camera uses the Canny edge detection algorithm through the internally integrated vision system to identify the edge contour of the metal profile. Then, through morphological processing and the Hough transform method, the specific shape of the metal profile is identified. Through image calibration, the pixel size in the image is converted into the actual size, accurately measuring the length, width, height and other dimensions of the metal profile, and being able to match the identified shape with the preset shape model to confirm the type of the metal profile, enabling it to automatically identify the metal profile and automatically adjust the corresponding cutting path.

[0015] 2.

[0021] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0022] As Figures 1 - 3 shown, this embodiment provides a planar laser cutting machine, including: an operating table 1, a feeding mechanism 3 is fixedly installed on the upper surface of the operating table 1, a longitudinal slide rail 101 is fixedly installed on the upper surface of the operating table 1, a first linear module 102 is slidably installed on the outer surface of the longitudinal slide rail 101, a connecting block 103 is fixedly installed on the upper surface of the first linear module 102, a transverse slide rail 104 is fixedly installed on the outer surface of the connecting block 103, a second linear module 105 is slidably installed on the outer surface of the transverse slide rail 104, a vertical third linear module 106 is fixedly installed at one end of the second linear module 105, a laser cutting machine 4 is fixedly installed at one end of the moving block of the vertical third linear module 106, an L-shaped plate 5 is fixedly installed on the upper surface of the operating table 1, and a CCD camera 501 is fixedly installed at one end of the L-shaped plate 5.

[0023] The lens of the CCD camera 501 is inclined to face the feeding mechanism 3.

[0024] The signal output end of the CCD camera 501 is connected to the signal receiving end of the controller, and the signal transmitting end of the controller is connected to the signal receiving ends of the first linear module 102 and the second linear module 105, so that the CCD camera 501 can provide a vision function for the first linear module 102 and the second linear module 105, and drive the laser cutting machine 4 to perform an accurate cutting trajectory movement.

[0025] Through the design of the first linear module 102, the CCD camera 501, the second linear module 105, the laser cutting machine 4 and the feeding mechanism 3, when the staff place the metal profile on the upper surface of the feeding mechanism 3, the CCD camera 501 uses the Canny edge detection algorithm through the integrated vision system inside to identify the edge contour of the metal profile. Then, through morphological processing and the Hough transform method, the specific shape of the metal profile is identified. Then, through image calibration, the pixel size in the image is converted into the actual size, accurately measuring the dimensions such as the length, width and height of the metal profile, and being able to match the identified shape with the preset shape model to confirm the type of the metal profile, enabling it to automatically identify the metal profile and automatically adjust the corresponding cutting path. Then, the measured dimensions are compared with the preset dimension standard, and then according to the shape of the placement position of the metal profile again, the cutting path is re-planned to ensure the cutting accuracy and efficiency. After the detection is completed, the controller sends the cutting path to the first linear module 102 and the second linear module 105 to drive the laser cutting machine 4 to perform the cutting operation. During the entire cutting process, the CCD camera 501 will continuously monitor the cutting process and give real-time feedback on the cutting effect. If any deviation is found, the system will automatically adjust the parameters to ensure the cutting quality.

[0026] As Figure 4 shown, the feeding mechanism 3 includes a square frame 301 which is fixedly installed on the upper surface of the operating table 1. Inside the square frame 301, multiple groups of connecting rods 302 are fixedly installed. Between the multiple groups of connecting rods 302, load-bearing sheets 303 are designed vertically and horizontally, so that square openings are formed between the vertically and horizontally arranged load-bearing sheets 303.

[0027] The lower surface of the square frame 301 is fixedly installed with a conical funnel 304, and the conical funnel 304 is communicated with the square opening formed between the load-bearing sheets 303.

[0028] The conical funnel 304 is flush with the storage barrel 2, and the storage barrel 2 is detachably installed between the four legs of the operating table 1.

[0029] Through the design of the load-bearing sheets 303 and the conical funnel 304, after the metal profile is placed on the upper surface of the load-bearing sheets 303, and then when the laser cutting machine 4 is started to cut the metal profile, the metal chips generated after cutting fall from the square opening formed between the vertically and horizontally arranged load-bearing sheets 303 into the conical funnel 304, and the chips will fall into the storage barrel 2 through the conical funnel 304 for centralized collection, which can avoid the situation that the metal profile is jacked up due to the chips remaining on the upper surface of the load-bearing sheets 303 or the connecting rods 302, resulting in unstable placement.

[0030] Summarize and sort out the working steps of this solution according to the above technical solution: When in use, by placing the metal profile on the upper surface of the bearing plate 303, the metal profile will be within the visual range of the CCD camera 501. The CCD camera 501 uses the Canny edge detection algorithm through the internally integrated vision system to identify the edge contour of the metal profile, and then uses morphological processing and Hough transform methods to identify the specific shape of the metal profile. Then, through image calibration (calibration), the pixel size in the image is converted into the actual size, and the dimensions such as the length, width, and height of the metal profile are accurately measured. The identified shape can be matched with the preset shape model to confirm the type of the metal profile. Then, the measured dimensions are compared with the preset dimension standard. Then, according to the shape of the placement position of the metal profile again, the cutting path is re-planned to ensure the cutting accuracy and efficiency. After the detection is completed, the controller sends the cutting path to the first linear module 102 and the second linear module 105 to drive the laser cutting machine 4 to perform the cutting operation. During the entire cutting process, the CCD camera 501 will continuously monitor the cutting process and provide real-time feedback on the cutting effect. If any deviation is found, the system will automatically adjust the parameters to ensure the cutting quality. The metal chips generated after cutting fall into the conical funnel 304 through the square openings formed between the bearing plates 303 arranged vertically and horizontally, and the chips will fall into the storage cylinder 2 through the conical funnel 304 for centralized collection.

[0031] In summary, it has the effect of automatically identifying metal profiles and automatically adjusting the corresponding cutting path, eliminating the waiting time required for manual adjustment by workers, improving the cutting efficiency while increasing the cutting accuracy, and being able to centrally collect metal chips during cutting, which can avoid the situation where the metal profile is lifted up due to chips remaining on the upper surface of the bearing plate 303 or the connecting rod 302, resulting in unstable placement.

[0032] It should be noted that the controller can be selected as an S7-200 ultra-small PLC controller.
