Description

Technical Field

[0001] The present invention belongs to the technical field of laser cutting, and in particular relates to a ceramic sheet laser cutting device and a use method thereof. Background Art

[0002] Ceramic laser cutting is an advanced processing technology used for the engraving and cutting of porcelain. It has the characteristics of non-contact, flexibility, automation, precision cutting, curve cutting, narrow slits, and fast speed. In the process of ceramic laser cutting, absorbents are often used to improve cutting efficiency and processing quality.

[0003] The prior art discloses some invention patents in the field of laser cutting technology, among which the invention patent with publication number CN107570889A discloses a method for laser cutting ceramics, including the following steps: adjusting the laser in the cutting system, recombining the laser frequency so that multiple laser pulses fall on the same point of the workpiece, first scanning the same processing path of the part to be cut on the ceramic body with a lower power laser for multiple times to continuously advance the processing depth, and then switching to a high power laser to complete the cutting after reaching a certain thickness. In step five, compressed air is blown into the cutting part of the ceramic body to blow away the vaporized and / or cut materials. After the ceramic laser cutting absorbent in this technical solution is coated on the ceramic surface, the ceramic can increase the laser resistance. Absorption rate, the efficiency of ceramic laser processing and the yield rate of products after coating with absorbent are greatly improved, and the absorbent is a pollution-free environmentally friendly material, which will not increase the pollution to the environment during the processing; and this method has the simplest process, which can control the size of microcracks within the range of grain size, and the cutting surface is smooth and without cutting marks. However, there are still some shortcomings in the application of this technical solution. When the laser cutting equipment is cutting ceramic sheets, if the temperature is too high, the surface uniformity of the absorbent coated on the surface of the ceramic sheets is prone to change. When the surface uniformity of the absorbent is reduced, the laser absorption effect is changed, which will affect the laser cutting accuracy. If the temperature is low, the absorbent cannot be decomposed quickly and cannot release enough energy to cut the ceramic sheets.

[0025] A guide blade is rotatably connected inside the cylinder, an exhaust nozzle is connected to the cylinder, the other end of the exhaust nozzle is connected to a drying pipe, and the other end of the drying pipe is connected to a drying nozzle.

[0026] A method for using a ceramic sheet laser cutting device comprises the following steps:

[0027] The ceramic sheets to be cut are evenly placed on the position of the feeding belt corresponding to the drying channel, and the feeding belt is controlled by the CNC feeding workbench to transport the ceramic sheets to be cut. When the ceramic sheets to be cut are sent to the bottom of the built-in laser head of the CNC laser cutter, the bottom of the connecting plate is slidably connected to the cutting surface of the ceramic sheets to be cut. A large amount of dust and gas will be generated in the process of cutting the ceramic sheets by the CNC laser cutter, and high temperature will also be generated. The motor B is controlled to run, and the output shaft of the motor B drives the active bevel gear. By utilizing the linkage relationship between the active bevel gear and the driven bevel gear, the motor B applies torque to the drainage fan through the gear set formed by the combination of the active bevel gear and the driven bevel gear. The drainage fan rotates rapidly between the outer sleeve and the inner sleeve. The rotation of the drainage fan acts on the inner sleeve through multiple discharge holes A. Gas and dust flow into the interlayer formed by the combination of the outer sleeve and the inner sleeve through multiple discharge holes. The air enters the inner sleeve through the gap on the feeding belt and rotates under the action of the guide head.

[0028] The gas and dust entering the interlayer flow upwards. After being sent to the top of the drainage fan, the gas and dust flow out through the discharge pipe, and then flow into the cylinder in the tangential direction through the introduction pipe. The gas and dust will change from linear motion to circular motion. Most of the rotating airflow flows downward in a spiral shape from the conical cylinder along the wall toward the inner bottom of the conical cylinder. The dust is thrown toward the inner wall of the conical cylinder under the action of centrifugal force. Once the dust contacts the inner wall of the conical cylinder, it loses its inertial force and falls along the wall with the momentum of the downward axial velocity near the inner wall of the conical cylinder and enters the sewage discharge nozzle. The rotating and descending external rotating gas continuously flows into the central part of the conical cylinder during the descent process, forming a centripetal radial airflow. This part of the airflow constitutes a rotating upward internal vortex. The rotation directions of the internal and external vortexes are the same. Finally, the gas flows out through the exhaust nozzle.

[0029] The gas discharged from the exhaust nozzle enters the drying nozzle through the drying pipe, and finally flows from one end of the drying channel to the other end through the drying nozzle.

[0030] Twist the adjustment knob, the threaded rod will move up and down inside the adjustment knob, and the threaded rod will drive the drying nozzle to move up and down synchronously. The height of the drying nozzle can be adjusted according to the thickness of the ceramic piece to be cut, which is used to adapt to the laser cutting processing of different types of ceramic pieces.

[0031] When the CNC laser cutter cuts ceramic sheets, it is also necessary to control the position of the guide head according to the cutting trajectory, control the operation of motor A, and the output shaft of motor A drives the driving gear to rotate, the driving gear drives the driven gear, and the driven gear drives the outer sleeve to rotate. The outer sleeve drives the inner sleeve to rotate synchronously through the connecting plate, so that the position of the guide head can be changed according to the change of the laser cutting trajectory, so that the flow direction of the air changes after flowing into the inner sleeve through the gap on the feeding belt.

[0032] In summary, due to the adoption of the above technical solution, the beneficial effects of the present invention are:

[0033] 1. In the present invention, the gas carries the heat energy generated by the CNC laser cutter when cutting the ceramic sheet, and the flow direction of the gas is opposite to the transmission direction of the feeding belt, so that the absorbent of the ceramic sheet to be cut on the feeding belt can be dried well, avoiding the absorbent's initial drying temperature being too high and reducing the uniformity, and avoiding a negative impact on the cutting quality. After the ceramic sheet to be cut is dried, the CNC laser cutter immediately completes the cutting process. At this time, the surface temperature of the absorbent is high, and the absorbent can be quickly decomposed under laser irradiation, releasing sufficient energy to cut the ceramic material, thereby achieving faster and more precise cutting.

[0034] 2. In the present invention, the gas and dust entering the interlayer flow upward, and after being sent to the top of the drainage fan, the gas and dust flow out through the discharge pipe, and then flow into the cylinder in a tangential direction through the introduction pipe. The gas and dust will change from linear motion to circular motion, and the vast majority of the rotating airflow will flow downward in a spiral shape from the conical cylinder along the wall toward the inner bottom of the conical cylinder. Under the action of centrifugal force, the dust is thrown toward the inner wall of the conical cylinder. Once the dust contacts the inner wall of the conical cylinder, it loses its inertial force, and falls along the wall surface by the momentum of the downward axial velocity near the inner wall of the conical cylinder, and enters the sewage discharge nozzle. The rotating and descending external rotating gas continuously flows into the central part of the conical cylinder during the descent process, forming a centripetal radial airflow, and this part of the airflow constitutes a rotating upward internal vortex, and the rotation directions of the internal and external vortexes are the same. Finally, the gas flows out through the exhaust nozzle, and the cutting part of the ceramic sheet is quickly dissipated, which not only realizes the recovery and utilization of heat energy, but also accelerates the heat dissipation of the cut ceramic sheet, and the use effect is good.

[0058] The ceramic sheets to be cut are evenly placed on the position of the feeding belt 2 corresponding to the drying channel 701, and the CNC feeding workbench 1 controls the feeding belt 2 to convey the ceramic sheets to be cut. When the ceramic sheets to be cut are sent to the bottom of the built-in laser head of the CNC laser cutter 3, the bottom of the connecting plate 404 is slidably connected to the cutting surface of the ceramic sheets to be cut. A large amount of dust and gas will be generated in the process of cutting the ceramic sheets by the CNC laser cutter 3, and high temperature will also be generated.

A method for using a ceramic sheet laser cutting device, using the ceramic sheet laser cutting device as claimed in claim 9, characterized in that: The following steps are involved: The ceramic sheets to be cut are evenly placed on the feeding belt (2) at positions corresponding to the drying channel (701), and the feeding belt (2) is controlled by the numerical control feeding workbench (1) to convey the ceramic sheets to be cut. When the ceramic sheets to be cut are conveyed to the bottom of the built-in laser head of the numerical control laser cutter (3), the bottom of the connecting plate (404) is slidably connected to the cutting surface of the ceramic sheets to be cut. A large amount of dust and gas will be generated in the process of cutting the ceramic sheets by the numerical control laser cutter (3), and high temperature will also be generated. The motor B (504) is controlled to operate, and the output shaft of the motor B (504) drives the active bevel gear (503). The active bevel gear (503) and the driven bevel gear ( The motor B (504) exerts torque on the drainage fan (501) through a gear set formed by a combination of an active bevel gear (503) and a driven bevel gear (502), and the drainage fan (501) rotates rapidly between the outer sleeve (402) and the inner sleeve (403). The drainage fan (501) rotates and acts on the inner sleeve (403) through a plurality of discharge holes A (507). Gas and dust flow into the interlayer formed by the combination of the outer sleeve (402) and the inner sleeve (403) through the plurality of discharge holes. The air enters the inner sleeve (403) through the gap on the feeding belt (2), and performs a rotational motion under the action of the guide head (405); The gas and dust entering the interlayer flow upwards, and after being sent to the top of the induced draft fan (501), the gas and dust flow out through the discharge pipe (506), and then flow into the cylinder (602) in a tangential direction through the introduction pipe (604). The gas and dust will change from linear motion to circular motion. Most of the rotating airflow flows downward in a spiral shape from the conical cylinder (607) along the wall of the device toward the inner bottom of the conical cylinder (607). The dust is thrown into the conical cylinder (607) under the action of centrifugal force. Once the dust contacts the inner wall of the conical cylinder (607), it loses its inertial force and falls along the wall surface with the momentum of the downward axial velocity near the inner wall of the conical cylinder (607) and enters the sewage discharge nozzle (605). The outer swirling gas that rotates downward continuously flows into the central part of the conical cylinder (607) during the downward process, forming a centripetal radial airflow. This part of the airflow constitutes an inner swirling flow that rotates upward. The rotation directions of the inner and outer swirling flows are the same. Finally, the gas flows out through the exhaust nozzle (606); The gas exhausted through the exhaust nozzle (606) enters the drying nozzle (702) through the drying pipe (707), and finally is ejected through the drying nozzle (702) and flows from one end to the other end of the drying channel (701); By twisting the adjusting knob (706), the threaded rod (705) will move up and down inside the adjusting knob (706), and the threaded rod (705) will drive the drying nozzle (702) to move up and down synchronously, and the height of the drying nozzle (702) can be adjusted according to the thickness of the ceramic sheet to be cut, so as to adapt to the laser cutting processing of ceramic sheets of different models; When the CNC laser cutter (3) is cutting a ceramic sheet, it is also necessary to control the position of the guide head (405) according to the cutting trajectory, control the operation of the motor A (4063), the output shaft of the motor A (4063) drives the driving gear (4062) to rotate, the driving gear (4062) drives the driven gear (4061), and the driven gear (4061) drives the outer sleeve (402) to rotate, the outer sleeve (402) drives the inner sleeve (403) to rotate synchronously through the connecting plate (404), so that the position of the guide head (405) can be changed according to the change of the laser cutting trajectory, so that the flow direction of the air changes after it flows into the inner sleeve (403) through the gap on the feeding belt (2).
