Description

Technical Field

[0001] The present invention relates to the technical field of laser cutting machines, and in particular to a bridge-type automatic laser cutting machine. Background Art

[0002] A laser cutting machine is a CNC machine tool that uses a high-power density laser beam to precisely cut materials. It is an advanced manufacturing equipment that highly integrates lasers, precision machinery, CNC systems, and auxiliary gas systems. It can efficiently and accurately cut a variety of materials such as metals and non-metals. Among them, the bridge-type automated laser cutting machine is currently the most widely used type of laser cutting machine. Unlike other laser cutting machines, the motion mechanism of the laser cutting head in the bridge-type automated laser cutting machine adopts a gantry design, spanning the workbench (or processing area) like a bridge. It has high rigidity and stability, and is particularly suitable for large-format, high-load, and precision cutting scenarios.

[0003] During the use of the bridge-type automatic laser cutting machine, first of all, since the bridge structure is in a fixed state as a whole and the bridge structure is relatively large, a large amount of metal dust and powder will be generated during laser cutting. These metal dust and powder adhere to the laser cutting head and the bridge structure, which will greatly affect the normal operation of the laser cutting head and the normal operation of the bridge structure. It is often necessary to stop the machine for cleaning, which greatly delays the normal laser cutting effect. In addition, during the laser cutting process, the object to be cut will be placed on the honeycomb support table, and the generated debris and small particles will fall into the honeycomb support table, which is convenient for subsequent collection operations. However, in the actual laser cutting process, some debris and small particles will be stuck in the holes of the honeycomb support table, affecting the normal operation of the honeycomb support table. Therefore, a bridge-type automatic laser cutting machine is provided. Summary of the Invention

DETAILED DESCRIPTION

[0028] See Figures 1-8 A bridge-type automated laser cutting machine comprises a main body 1, a plurality of support rods 12 are fixedly connected to the lower side of the main body 1, a transport assembly 3 is installed on the upper side of the main body 1, the transport assembly 3 comprises a transport motor fixedly installed in the main body 1, a plurality of transport rods are rotatably connected in the main body 1, and a transport belt is commonly connected to the outer sides of the plurality of transport rods, one of the transport rods is fixedly connected to the output end of the transport motor, a honeycomb support platform 4 is fixedly connected to the upper side of the main body 1, a bridge body 2 is slidably installed on the upper side of the main body 1, a movable frame 7 is slidably connected to the outer side of the bridge body 2, a working plate 8 is fixedly connected to the lower side of the movable frame 7, and the lower side of the working plate 8 is rotatably connected There is a laser cutting head 23, and a control component for controlling the movement of the bridge body 2 and the moving frame 7 is installed on the upper side of the main body 1. The control component includes a first motor 5 fixedly installed on both sides of the main body 1, and the output ends of the two first motors 5 are fixedly connected to the first threaded rod 6. The first threaded rod 6 is threaded through the bridge body 2. The side wall of the bridge body 2 is rotatably connected to two second threaded rods 10. The two second threaded rods 10 are connected by a first pulley assembly. The second threaded rod 10 is threaded through the moving frame 7. The side wall of the bridge body 2 is fixedly connected to the second motor 9, and one of the second threaded rods 10 is fixedly connected to the output end of the second motor 9;

[0029] First, under the action of the two first threaded rods 6 and the two second threaded rods 10, the uneven force phenomenon of the bridge body 2 and the movable frame 7 during movement can be reduced. Then, the first motor 5 and the second motor 9 are electrically connected to the controller and the display screen on the front side of the main body 1 through wires. During the laser cutting process, the corresponding signal can be adjusted through the display screen so that the controller can automatically adjust the switches of the first motor 5 and the second motor 9, and finally complete the movement control operation of the bridge body 2 and the movable frame 7, and the laser cutting operation can be performed. When laser cutting is required, the material to be processed is placed on the conveyor belt, and the conveyor motor is started. The conveyor motor drives the conveyor rod to rotate, and the conveyor rod drives the conveyor belt to move, thereby moving the material to be processed into the processing area, that is, the upper side of the honeycomb support platform 4 (since both sides of the honeycomb support platform 4 are smooth inclined surfaces, After the processed material moves to the inclined surface of the honeycomb support platform 4, it continues to move under the action of inertia until it moves to the upper side of the honeycomb support platform 4), and laser cutting begins. After the laser cutting is completed, multiple cameras and robotic arms are installed on the upper side of the honeycomb support platform 4. The cameras and robotic arms are electrically connected to the controller. When the object first moves to the upper side of the honeycomb support platform, the controller can locate the object through the camera, and then start the robotic arm. Under the action of the robotic arm, the position of the object on the upper side of the honeycomb support platform 4 is adjusted until the position of the object meets the processing requirements. After the laser cutting operation is completed, the controller can start the robotic arm and the transport motor again to first move the cut object from the honeycomb support platform 4 to the upper side of the conveyor belt, and then take the cut material out through the conveyor belt to facilitate the next laser cutting operation. The above technology is a mature and well-known technology and will not be described in detail.

[0030] A cleaning assembly is installed on the side wall of the bridge body 2, and the cleaning assembly includes a cleaning cylinder 34, the upper side of the cleaning cylinder 34 is rotatably connected to a rotating ring 32, a first torsion spring 33 is fixedly connected between the rotating ring 32 and the cleaning cylinder 34, the working plate 8 is rotatably connected to a moving ring 28, the rotating ring 32 and the moving ring 28 are slidably connected, a plurality of first springs 31 are fixedly connected between the rotating ring 32 and the moving ring 28, the side wall of the bridge body 2 is evenly fixedly connected to a plurality of first racks 11, the side wall of the working plate 8 is rotatably connected to a rotating shaft 15, the upper side of the rotating shaft 15 is fixedly connected to a first gear 19 matching the first rack 11, a second torsion spring 20 is fixedly connected between the first gear 19 and the working plate 8, and the rotating shaft 15 is transmission-connected to the moving ring 28 through a second pulley assembly 22;

[0031] First, a brush is fixedly connected to the inner wall of the cleaning cylinder 34, and the brush is against the outer wall of the laser cutting head 23. Secondly, a controller for controlling the operation of the laser cutting head 23 is installed on the front side of the body 1. A display screen is also fixedly connected to the front side of the body 1. The display screen and the controller are electrically connected through a wire. The display screen can not only simulate the running trajectory of the laser cutting head 23, but also display the operating status of the laser cutting head 23. The working status of the laser cutting head 23 can be adjusted through the display screen, thereby completing a variety of different laser cutting tasks.

[0032] During the laser cutting process, when the moving frame 7 moves relative to the bridge body 2, since the first rack 11 and the bridge body 2 are fixedly connected, when the moving frame 7 moves relative to the bridge body 2, the first gear 19 and the rotating shaft 15 will rotate as a whole, and the rotating shaft 15 will drive the moving ring 28 to rotate through the second pulley assembly 22. The moving ring 28 drives the rotating ring 32 to rotate through the first spring 31, and the rotating ring 32 drives the cleaning cylinder 34 to rotate through the first torsion spring 33. The brush inside the cleaning cylinder 34 and the laser cutting head 23 are against each other, which can form a cleaning effect on the surface of the laser cutting head 23, reducing the possibility of metal powder and dust sticking to the surface of the laser cutting head 23, thereby keeping the laser cutting head 23 in good working condition. When the first gear 19 and the first rack 11 are disconnected, under the action of the second torsion spring 20, the cleaning cylinder 34 will rotate again, and the cleaning cylinder 34 will return to its original position relative to the laser cutting head 23 until the first gear 19 is engaged with the first gear 19 again, and the cleaning cylinder 34 repeats the above operation again.

[0033] A striking assembly is installed on the lower side of the bridge body 2. The striking assembly includes a threaded plate 21 fixedly mounted on the lower side of the rotating shaft 15. A trapezoidal ring 30 is fixedly connected to the outer side of the cleaning cylinder 34. A mounting ring is rotatably connected to the outer side of the trapezoidal ring 30. Two cross bars 16 are symmetrically fixedly connected to the outer side of the mounting ring. A striking frame 17 is slidably connected to the outer sides of the two cross bars 16. The striking frame 17 and the bridge body 2 are slidably connected up and down. A striking head 18 is fixedly connected to the lower side of the striking frame 17.

[0034] First, the shape of the threaded plate 21 is as follows Figure 5As shown, one of the cross bars 16 is located in the threaded groove of the side wall of the threaded plate 21. During the rotation of the rotating shaft 15, the rotating shaft 15 drives the threaded plate 21 to rotate, and the threaded plate 21 drives the cross bar 16 and the trapezoidal ring 30 to move downward relative to the movable ring 28, thereby expanding the cleaning range of the cleaning cylinder 34. At the same time, the downward moving cross bar 16 drives the knocking frame 17 to move downward, and the knocking frame 17 drives the knocking head 18 to move downward. The knocking head 18 and the honeycomb support platform 4 are offset against each other, which will form a knocking effect on the honeycomb support platform 4, and can make the dust accumulated in the inner hole of the honeycomb support platform 4 fall off, maintain the normal circulation of the honeycomb support platform 4, and thus make the metal powder fall better on the honeycomb support platform 4, so that the honeycomb support platform 4 can play a better role.

[0035] A plurality of vacuum cleaners 24 are also fixedly connected to the lower side of the movable frame 7. The plurality of vacuum cleaners 24 are arranged in a circle outside the laser cutting head 23.

[0036] The dust collector 24 can absorb the smoke generated during a laser cutting, eliminate metal powder and toxic gases as much as possible, and maintain the safety of the processing environment. The dust collector 24 is a synonym for a centralized dust removal system, which is mainly composed of a dust hood (covering the cutting area and capturing flying dust), an air duct system (conveying dust), a cyclone separator (primary filtration), a pulse back-blowing filter cartridge (secondary filtration), a negative pressure fan (providing system power), and a dust collection bucket (storing separated metal powder). Through "negative pressure capture → centrifugal pre-separation → filter cartridge fine filtration → pulse regeneration", efficient cleaning can be achieved, which can greatly reduce metal dust in the cutting area and has a good dust removal effect. This is an existing technology and no unnecessary elaboration is made.

[0037] A collision assembly is installed on the outside of the bridge body 2, and the collision assembly includes a second gear 29 fixedly installed on the outside of the moving ring 28. The outside of the second gear 29 is meshed with a second rack 25, and the second rack 25 is slidably connected to the working plate 8. The side wall of the second rack 25 is fixedly connected to a fixed rod 26. The outside of the second gear 29 is also meshed with a third rack 27, and the third rack 27 is slidably connected to the working plate 8. The side wall of the third rack 27 is fixedly connected to a connecting frame 14, and the side wall of the connecting frame 14 is fixedly connected to two cleaning frames 13;

[0038] First, the vacuum cleaner 24 is fixedly connected to the working plate 8 through memory metal (memory metal refers to a metal material that can restore its original shape at a specific temperature). Secondly, during the laser cutting process, the moving ring 28 drives the second gear 29 to rotate, the second gear 29 drives the second rack 25 to move, and the second rack 25 drives the fixed rod 26 to move. The fixed rod 26 and the vacuum cleaner 24 are offset, which will drive the vacuum cleaner 24 to move, causing the working direction of the vacuum cleaner 24 to change, thereby expanding the working range of the vacuum cleaner 24 and better forming the dust collection and cleaning effect of the main body 1. Then, when the second gear 29 rotates, the second gear 29 drives the third rack 27 to move, and the third rack 27 drives the cleaning frame 13 to move through the connecting frame 14. The cleaning frame 13 is located on the lower side of the second threaded rod 10. A sponge is fixedly connected to the upper side of the cleaning frame 13. The sponge can clean the dust stuck to the outside of the second threaded rod 10, maintain the cleanliness of the second threaded rod 10, and finally enable the second threaded rod 10 to maintain the overall transmission effect.

[0039] In the present invention, when laser cutting is required, the material to be processed is placed on the conveyor belt, the conveyor motor is started, the conveyor motor drives the conveyor rod to rotate, and the conveyor rod drives the conveyor belt to move, thereby moving the material to be processed into the processing area, that is, the upper side of the honeycomb support platform 4 (since both sides of the honeycomb support platform 4 are smooth inclined surfaces, after the material to be processed moves to the inclined surface of the honeycomb support platform 4, it continues to move under the action of inertia until it moves to the upper side of the honeycomb support platform 4), and laser cutting is started. After the laser cutting is completed, multiple cameras and machine tools are installed on the upper side of the honeycomb support platform 4. The robotic arm, the camera and the robotic arm are all electrically connected to the controller. When the object is first moved to the upper side of the honeycomb support platform, the controller can locate the object through the camera and then start the robotic arm. Under the action of the robotic arm, the position of the object on the upper side of the honeycomb support platform 4 is adjusted until the position of the object meets the processing requirements. After the laser cutting operation is completed, the controller can start the robotic arm and the transport motor again to first move the cut object from the honeycomb support platform 4 to the upper side of the conveyor belt, and then the cut material is taken out through the conveyor belt to facilitate the next laser cutting operation. The above are all existing technologies and no redundant elaboration is made.

[0040] During the laser cutting process, when the moving frame 7 moves relative to the bridge body 2, since the first rack 11 and the bridge body 2 are fixedly connected, when the moving frame 7 moves relative to the bridge body 2, the first gear 19 and the rotating shaft 15 will rotate as a whole, and the rotating shaft 15 will drive the moving ring 28 to rotate through the second pulley assembly 22. The moving ring 28 drives the rotating ring 32 to rotate through the first spring 31, and the rotating ring 32 drives the cleaning cylinder 34 to rotate through the first torsion spring 33. The brush inside the cleaning cylinder 34 and the laser cutting head 23 are against each other, which can form a cleaning effect on the surface of the laser cutting head 23, reducing the possibility of metal powder and dust sticking to the surface of the laser cutting head 23, thereby keeping the laser cutting head 23 in good working condition. When the first gear 19 and the first rack 11 are disconnected, the cleaning cylinder 34 will rotate again under the action of the second torsion spring 20, and the cleaning cylinder 34 will return to its original position relative to the laser cutting head 23 until the first gear 19 is meshed with the first gear 19 again, and the cleaning cylinder 34 repeats the above operation again;

[0041] During the rotation of the rotating shaft 15, the rotating shaft 15 drives the threaded plate 21 to rotate, and the threaded plate drives the cross bar 16 and the trapezoidal ring 30 to move downward relative to the movable ring 28, thereby expanding the cleaning range of the cleaning cylinder 34. At the same time, the downwardly moving cross bar 16 drives the knocking frame 17 to move downward, and the knocking frame 17 drives the knocking head 18 to move downward. The knocking head 18 and the honeycomb support platform 4 are offset against each other, forming a knocking effect on the honeycomb support platform 4, which can make the dust accumulated in the inner hole of the honeycomb support platform 4 fall off, maintain the normal circulation of the honeycomb support platform 4, and then make the metal powder fall better on the honeycomb support platform 4, so that the honeycomb support platform 4 can play a better role.

[0042] During the laser cutting process, the moving ring 28 drives the second gear 29 to rotate, and the second gear 29 drives the second rack 25 to move, and the second rack 25 drives the fixed rod 26 to move. The fixed rod 26 and the dust collector 24 are offset, which will drive the dust collector 24 to move, causing the working direction of the dust collector 24 to change, thereby expanding the working range of the dust collector 24, and better forming the dust collection and cleaning effect of the main body 1. Then, when the second gear 29 rotates, the second gear 29 drives the third rack 27 to move, and the third rack 27 drives the cleaning frame 13 to move through the connecting frame 14. The cleaning frame 13 is located on the lower side of the second threaded rod 10. A sponge is fixedly connected to the upper side of the cleaning frame 13. The sponge can clean dust stuck to the outside of the second threaded rod 10, maintain the cleanliness of the second threaded rod 10, and finally enable the second threaded rod 10 to maintain the overall transmission effect.
