Description

Technical Field

[0001] The utility model relates to the technical field of soft porcelain processing, in particular to an automatic soft porcelain cutting system. Background Art

[0002] Laser cutting uses a high-power density laser beam to irradiate the material to be cut, so that the material is quickly heated to the vaporization temperature and evaporated to form holes. As the beam moves on the material, the holes continuously form a very narrow slit to complete the cutting of the material. Therefore, laser cutting is fast, less affected by the material, and has good overall cutting quality. However, the equipment is expensive and the cutting thickness can only adapt to medium and small thicknesses. At present, lasers mainly rely on the high temperature brought by their high-energy laser beams to melt, vaporize and ablate the material, and then blow away the material through the high-temperature airflow coaxially blown out by the laser head to achieve cutting. Among them, in the cutting of soft porcelain, soft porcelain is prone to produce aerosol particles due to the high temperature when using laser cutting. The aerosol particles will reduce the penetration of the laser, thereby reducing the cutting effect of the laser beam. In addition, the cutting dust can easily block the line of sight and prevent staff from viewing the cutting process.

[0003] In response to this situation, the patent publication number is CN113118644A-Laser Cutting Robot, which discloses the advantages of easy loading and unloading, position adjustment and effective limit, dust absorption and effective protection, solving the problem of the traditional technology that the main body affects the working environment and is not conducive to effective protection when in use. However, the robot is simply equipped with a suction mechanism. Although the suction mechanism can remove the flying dust in the air, its suction power cannot be adjusted. Therefore, when the suction power is small, the dust cannot be effectively removed. When the suction power is large, although the dust can be removed, it will also take away the energy of the laser beam, thereby affecting the cutting effect. Utility Model Content

DETAILED DESCRIPTION

[0025] In order to make the purpose, technical solution and advantages of the utility model more clear, the utility model is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the utility model and are not used to limit the utility model.

[0026] Reference Figures 1 to 4A soft porcelain automated cutting system is shown, comprising a frame 10 and a laser cutting head 20 capable of moving on the frame 10, the frame 10 is provided with a dust removal system 30, the dust removal system 30 comprises a dust hood 31, a suction pipe 32 and a temporary storage tank 33, the dust hood 31 is mounted outside the laser cutting head 20, and can move synchronously with the laser cutting head 20, the two ends of the suction pipe 32 are respectively connected to the dust hood 31 and the temporary storage tank 33, the suction pipe 32 is provided with a suction pump 34, the inner wall of the dust hood 31 is provided with at least one dust concentration sensor 35, and the suction pump 34 can adjust its own working power according to the detection result of the dust concentration sensor 35.

[0027] Among them, the laser cutting head 20 is a conventional laser cutting component, which is not described in detail in this application. The laser melting cutting method adopted in this application is because the soft porcelain cut in this application is modified clay, so the laser is combined with a high-speed airflow to improve the cutting efficiency. The dust hood 31 in this application is a detachable structure, which is conducive to later cleaning and reduces dust deposition. At least three dust concentration sensors 35 are provided in this application. In actual use, any dust concentration sensor 35 automatically adjusts the power of the suction pump 34 after detecting that the dust concentration exceeds the standard.

[0028] In fact, in one embodiment of the present application, the rack 10 further includes a control cabinet 40, in which a controller is provided, and the controller is electrically connected to the dust concentration sensor 35 and the suction pump 34, and the controller can adjust the working power of the suction pump 34 according to the detection structure of the dust concentration sensor 35. A control panel is provided on the control cabinet, which is convenient for operation. The control principle of detecting data through sensors and adjusting the action of the actuator is a conventional principle. In the present application, the dust concentration sensor 35, the suction pump 34 and the controller are adapted to the above-mentioned system, and for this reason, the present application does not describe its working principle in detail.

[0029] The present soft porcelain automatic cutting system is improved on the existing laser cutting equipment, and a set of dust hood 31 is designed outside the laser cutting head 20, so that the dust hood 31 can move synchronously with the laser cutting head 20, thus adapting to the cutting action of the laser cutting head 20. At the same time, a dust concentration sensor 35 is set on the inner wall of the dust hood 31, and the dust concentration sensor 35 is used to measure the dust content in the dust hood 31, and then the working power of the suction pump 34 can be controlled, which can automatically adapt to the dust concentration, and can avoid taking away too much laser energy as much as possible while ensuring dust removal.

[0030] See also Figure 1 and Figure 2In order to carry soft porcelain, in one embodiment of the present application, a workbench 18 is provided on the frame 10, and the workbench 18 is located below the laser cutting head 20. In the present application, the workbench 18 is fixed and the laser cutting head 20 is moved to achieve cutting of different sizes.

[0031] In order to achieve a wide range of soft porcelain cutting, longitudinal rails 11 are provided on both sides of the frame 10, and sliding seats 12 are slidably installed on the two longitudinal rails 11. The two sliding seats 12 are connected by a transverse rail 13, and a driving seat 14 is slidably installed on the transverse rail 13. The laser cutting head 20 is installed on the driving seat 14, and a longitudinal driving mechanism for driving the sliding seat 12 to slide is provided on the longitudinal rail 11, and a transverse driving mechanism for driving the driving seat 14 to slide is provided on the transverse rail 13. In fact, the arrangement of the longitudinal rails 11 and the transverse rails 13 can be adjusted on the plane to a certain extent, and can basically adapt to the cutting of soft porcelain of different sizes. Both the longitudinal driving mechanism and the transverse driving mechanism can adopt a gear rack driving structure, or can adopt the cooperation of a screw rod and a screw rod nut, as long as sliding can be achieved; the longitudinal driving mechanism and the transverse driving mechanism are both electrically connected to the controller.

[0032] In the above-mentioned improved embodiment, the temporary storage tank 33 and the suction pump 34 are both arranged on the sliding seat 12, which makes it convenient for the staff to handle the deposited dust in the temporary storage tank 33 and repair the suction pump 34. There is no need to stand on the cross rail 13 as a whole, which reduces the difficulty of maintenance and cleaning.

[0033] In order to adapt to the cutting of soft porcelain of different thicknesses and improve the convenience of operation, a lifting mechanism is provided on the driving seat 14, and the laser cutting head 20 is installed on the lifting end of the lifting mechanism. More specifically, the lifting mechanism includes a seat body 15 and a lifting rod 16, and the lifting rod 16 can be slidably installed on the driving seat 14, and a rack 19 is provided on the lifting rod 16. A driving motor 17 is provided on the driving seat 14, and a gear matching the rack 19 is provided on the output end of the driving motor 17, and the laser cutting head 20 is installed on the seat body 15. In fact, the driving motor 17 is electrically connected to the controller, and the action of the driving motor 17 can be directly controlled by the control panel, and the controller can also be used to perform automatic cutting according to a preset program.

[0034] See also Figure 4In one embodiment of the present application, in order to avoid direct suction against the laser beam and improve the dust removal effect, a plurality of ridges 36 are provided on the inner wall of the dust hood 31, and suction slits 37 are provided on both sides of each ridge 36. An air collecting chamber 38 is provided on the back of the dust hood 31, and the air collecting chamber 38 is connected to all the suction slits 37, and the air collecting chamber 38 is connected to one end of the suction pipe 32. Among them, the ridges 36 can also play a role in strengthening the dust hood 31. In addition, in the present application, two adjacent suction slits 37 on non-same ridges 36 are arranged opposite to each other, and such an arrangement can jointly suck the area between the two ridges 36, disperse the flow of airflow to a certain extent, and reduce the problem of concentrated airflow and traction on the high-speed airflow outside the laser beam. In the present application, since the suction slits 37 are not directly facing the laser beam, the influence of the annular airflow outside the laser beam is small.

[0035] See also Figure 4 In one embodiment of the present application, since the laser cutting head 20 will not directly contact the material being cut during the actual cutting process, there must be a certain gap between the two. For this reason, the lower opening edge of the dust hood 31 is not located in the same plane as the lower end of the laser cutting head 20, and the laser cutting head 20 is higher than the plane where the lower opening edge of the dust hood 31 is located. Such a design can improve the dust collection effect to a certain extent. In addition, in order to facilitate the observation of the cutting effect, the dust hood 31 is made of transparent material. Of course, in some embodiments, since the laser cutting head 20 will not contact the surface of the material being cut, the lower end of the dust hood 31 will not contact the surface of the material, and the flow of air is used to suck the flying dust in the dust hood 31 to prevent the dust from flying out.

[0036] Furthermore, in one embodiment, in order to facilitate installation of the dust concentration sensor 35 , a mounting seat 39 is provided between the two convex ridges 36 on the dust collecting hood 31 , and the dust concentration sensor 35 is mounted on the mounting seat 39 .

[0037] The above-mentioned implementation modes are only preferred implementation modes of the present invention, and cannot be used to limit the protection scope of the present invention. Any non-substantial changes and substitutions made by technicians in this field on the basis of the present invention shall fall within the scope of protection required by the present invention.
