Description

Technical Field

[0001] The present invention relates to the technical field of laser cutting, and particularly relates to a laser die for numerical control cutting. Background Art

[0002] Laser cutting utilizes a high-power density laser medium to irradiate the cutting material, causing the material to be quickly heated to the vaporization temperature, evaporating to form holes. As the laser medium moves relative to the material, the holes continuously form a very narrow slit, completing the cutting of the material.

[0003] Among them, the patent with the publication number CN211708365U discloses a fixed-light laser die cutting machine, which relates to the technical field of mold making and packaging printing. It includes a machine frame, on which an operating table is arranged. There is a laser head cover on one side of the machine frame, an aluminum profile bracket on the front of the machine frame, a guide rail 1 on one side of the machine frame, an aluminum profile is installed on the machine frame, a guide rail 2 is arranged on the aluminum profile, a cross beam is arranged on the guide rail 1, a wooden board bracket is arranged on the cross beam, a drag chain is arranged on the wooden board bracket, a drag chain support plate is arranged on the drag chain, a mirror support frame is arranged inside the machine frame, a reflector is arranged on the mirror support frame, and a laser head frame is arranged below the mirror support frame.

[0004] When this structure is in use, the fixed-light laser die cutting machine adopts the movement of the plate. The X and Y direction movements are only the movement of the cutting material, and the workbench does not need to move, reducing the distance between the laser emitter and the machine tool to maintain the same distance. When cutting and moving, the load weight of the machine is reduced, so that the laser can move quickly during cutting, and the load weight of the machine will not increase due to the movement of the workbench. When cutting the material, only the material moves, and the workbench does not need to move back and forth, reducing the load weight of the servo motor and making the machine faster during cutting. However, this structure is not easy to focus the laser medium, resulting in a low quality of the laser medium during cutting and affecting the cutting efficiency. Summary of the Invention

[0005] The present invention provides a laser die for numerical control cutting, aiming to solve the problems raised in the above background art.

[0006] The present invention is implemented as follows. The present invention provides the following technical solution: A laser die for numerical control cutting includes a base, and a focusing and cutting assembly is arranged on the base.

[0007] The focusing and cutting assembly includes a connecting ring arranged on one side of the base. A rotating ring for placing the workpiece is rotatably connected to the connecting ring. A light pump is arranged on one side of the rotating ring, and a regulator for regulating the power of the light pump is arranged on the light pump.

[0008] One end of the light pump is provided with a focusing head, and a first laser head is embedded at one end of the focusing head.

[0009] A support sleeve is sleeved outside the focusing head. A number of extension frames for support are distributed on the support sleeve. A second laser head is arranged on one side of each of the multiple extension frames, and a refraction head is arranged at one end of each second laser head. One end of the focusing head facing the regulator is fixedly provided with a threaded sleeve, and the threaded sleeve extends to the regulator and is in threaded connection with the regulator. A limiting member is fixedly arranged on one side of the extension frame, a baffle is fixedly arranged at one end of the limiting member, a limiting cavity is formed on the outer side of the limiting member, the second laser head is matched with the limiting cavity, and the second laser head is embedded in the limiting cavity. A through hole is formed through the surface of the baffle, and one end of the refraction head extends into the through hole. A locking sleeve is sleeved outside the refraction head, a docking block is fixedly arranged on the locking sleeve, the docking block is located on one side of the inner cavity top of the limiting cavity, and the docking block extends to the bottom of the baffle.

[0010] It can be seen that in the above technical solution, after the filter of the optical pump is adjusted by the regulator, the laser emitted by the optical pump is used by the focusing head to focus the original laser medium emitted by the optical pump to form a light spot with a high energy density. The first laser head is used to change the ejection condition of the cutting beam, control the area and size of the diffusion of the laser medium, and ensure the cutting quality. When the laser medium is exported, each second laser head is used to guide the laser medium onto the laser medium ejected by the first laser head, and then change the curvature of the laser medium ejected by the first laser head. By changing the curvature of the laser medium, the divergence angle of the reflected light beam is changed, so as to change the focal position and realize the function of automatic focusing. This can save a lot of time and improve the laser cutting efficiency. Each baffle is inclined towards the pivot point of the support sleeve, so that the laser medium ejected by the second laser head can be refracted onto the laser medium ejected by the first laser head. At the same time, by rotating the threaded sleeve, the positions of the focusing head and the first laser head at one end of the regulator are adjusted, realizing the dynamic adjustment of the focal position and focal length, which is easy to be applied to cutting different materials or thicknesses, and can improve the cutting quality and efficiency.

[0011] Optionally, in a possible implementation manner, a support frame is arranged on one side of the connection ring. The support frame is installed on the base by bolts. A first sliding plate is slidably connected to the support frame. A second sliding plate is slidably connected to the first sliding plate. A third sliding plate is arranged on the top of the second sliding plate. An electric slide rail for driving the displacement of the third sliding plate is arranged on the second sliding plate. The optical pump is installed on the third sliding plate by bolts. A first lead screw transmission module for driving the displacement of the first sliding plate is arranged at one end of the support frame. A second lead screw transmission module for driving the displacement of the second sliding plate is arranged at one end of the first sliding plate. The multiple baffles are all circumferentially distributed along the pivot point of the support sleeve, and each baffle is inclined towards the pivot point of the support sleeve.

[0012] It can be seen that in the above technical solution, the swivel ring can also rotate on the connecting ring, which is convenient for cutting and processing different positions of the workpiece. At the same time, the first slide plate is driven by the first lead screw drive module to slide on the support frame, and the position of the second lead screw drive module, the second slide plate and the optical pump is adjusted first. After the second lead screw drive module is started, the second slide plate can slide on the first slide plate. At the same time, the third slide plate is driven by the electric slide rail to extend on the second slide plate, so that the optical pump can be positionally adjusted again to achieve the diversity and convenience during the cutting and processing of the workpiece. Through the settings of the locking sleeve, the docking block and the limiting cavity, after the second laser head is embedded in the limiting cavity, the docking block can be located at the bottom of the baffle, realizing the function of positioning after the second laser head is installed, and preventing the displacement of the second laser head and the refraction head, which may cause the laser medium ejected by the second laser head to be unable to be transmitted to the laser medium ejected by the first laser head.

[0013] The present invention has the following advantages:

[0014] 1. In the present invention, the filter of the optical pump is adjusted by the regulator. The laser emitted by the optical pump is used by the focusing head to focus the original laser medium emitted by the optical pump to form a light spot with a high energy density. The first laser head is used to change the ejection condition of the cutting beam, control the area and size of the diffusion of the laser medium, and ensure the cutting quality.

[0015] 2. Each second laser head in the present invention is used to guide the laser medium to the laser medium ejected by the first laser head, and then change the curvature of the laser medium ejected by the first laser head. By changing the curvature of the laser medium, the divergence angle of the reflected light beam is changed, thereby changing the focal position and realizing the function of automatic focusing. This can save a lot of time and improve the laser cutting efficiency.

[0016] 3. Each baffle in the present invention is inclined towards the pin point of the support sleeve, so that the laser medium ejected by the second laser head can be refracted on the laser medium ejected by the first laser head. At the same time, by rotating the threaded sleeve, the positions of the focusing head and the first laser head at one end of the regulator are adjusted, realizing the dynamic adjustment of the focal position and focal length, which is easy to be applied to cutting different materials or thicknesses, and can improve the cutting quality and efficiency.

[0017] 4. Through the settings of the locking sleeve, the docking block and the limiting cavity in the present invention, after the second laser head is embedded in the limiting cavity, the docking block can be located at the bottom of the baffle, realizing the function of positioning after the second laser head is installed, and preventing the displacement of the second laser head and the refraction head, which may cause the laser medium ejected by the second laser head to be unable to be transmitted to the laser medium ejected by the first laser head.

[0018] 5. In the present invention, the swivel ring can rotate on the connecting ring, which facilitates cutting and processing of different positions of the workpiece. The first slide plate slides on the support frame to initially adjust the positions of the second lead screw drive module, the second slide plate, and the optical pump. The electric slide rail drives the third slide plate to extend on the second slide plate, enabling the optical pump to be positionally adjusted again, so as to achieve the diversity and convenience during the cutting and processing of the workpiece.

[0019] In summary, through the coordinated use of each structure, the laser emitted by the optical pump is used by the focusing head to focus the original laser medium emitted by the optical pump, forming a light spot with a high energy density. The first laser head is used to change the ejection condition of the cutting beam, control the area and size of the diffusion of the laser medium, and ensure the cutting quality. Each second laser head is used to guide the laser medium onto the laser medium ejected by the first laser head, and then change the curvature of the laser medium ejected by the first laser head. By changing the curvature of the laser medium, the divergence angle of the reflected light beam is changed, thereby changing the focal position and realizing the function of automatic focusing. This can save a large amount of time and improve the laser cutting efficiency. The laser medium ejected by the second laser head can be refracted onto the laser medium ejected by the first laser head. At the same time, by rotating the threaded sleeve, the positions of the focusing head and the first laser head at one end of the regulator are adjusted, realizing the dynamic adjustment of the focal position and focal length, which is easy to apply for cutting on different materials or thicknesses, effectively ensuring the cutting quality and efficiency.

Each second laser head 15 is used to guide the laser medium to the laser medium ejected by the first laser head 8, and then change the curvature of the laser medium ejected by the first laser head 8. By changing the curvature of the laser medium, the divergence angle of the reflected light beam is changed, thereby changing the focal position and realizing the function of automatic focusing. This can save a lot of time and improve the laser cutting efficiency. The laser medium ejected by the second laser head 15 can be refracted on the laser medium ejected by the first laser head 8. At the same time, by rotating the threaded sleeve 7, the positions of the focusing head 6 and the first laser head 8 at one end of the regulator 5 are adjusted, realizing the dynamic adjustment of the focal position and focal length, which is easy to be applied to cutting different materials or thicknesses, effectively ensuring the cutting quality and efficiency, and the specific structural settings of the components are as follows.

A limiting member 11 is fixedly provided on one side of the extension frame 10. A baffle 12 is fixedly provided at one end of the limiting member 11. A limiting cavity 13 is formed on the outside of the limiting member 11. The second laser head 15 is matched with the limiting cavity 13, and the second laser head 15 is embedded in the limiting cavity 13. A through hole 14 is formed through the surface of the baffle 12. One end of the refraction head 17 extends into the through hole 14. A locking sleeve 16 is sleeved outside the refraction head 17. A docking block 18 is fixedly provided on the locking sleeve 16. The docking block 18 is located on one side of the inner cavity top of the limiting cavity 13, and the docking block 18 extends to the bottom of the baffle 12.

[0035] A support frame 19 is provided on one side of the connecting ring 2. The support frame 19 is installed on the base 1 by bolts. A first sliding plate 20 is slidably connected to the support frame 19. A second sliding plate 21 is slidably connected to the first sliding plate 20. A third sliding plate 22 is provided on the top of the second sliding plate 21. An electric slide rail 23 for driving the displacement of the third sliding plate 22 is provided on the second sliding plate 21. The light pump 4 is installed on the third sliding plate 22 by bolts.

[0036] When the above-mentioned structure is in use, the staff installs the device at the designated position. When welding a workpiece, the staff places the workpiece on the rotating ring 3, and at the same time, the rotating ring 3 can also rotate on the connecting ring 2, which is convenient for cutting and processing different positions of the workpiece. At the same time, the first lead screw drive module 24 drives the first slide plate 20 to slide on the support frame 19 to adjust the positions of the second lead screw drive module 25, the second slide plate 21 and the optical pump 4 first. After the second lead screw drive module 25 is started, the second slide plate 21 can slide on the first slide plate 20.

[0037] And during laser cutting, the filter of the optical pump 4 is adjusted by the regulator 5.

[0040] And through the settings of the locking sleeve 16, the docking block 18 and the limiting cavity 13, after the second laser head 15 is embedded in the limiting cavity 13, the docking block 18 can be located at the bottom of the baffle 12, realizing the function of positioning after the second laser head 15 is installed, and avoiding the displacement of the second laser head 15 and the refraction head 17, resulting in the inability of the laser medium ejected by the second laser head 15 to be transmitted to the laser medium ejected by the first laser head 8.

[0041] Different from the prior art, the present application discloses a laser die for numerical control cutting. The laser emitted by the optical pump 4 is focused by the focusing head 6 to form a light spot with a high energy density. The first laser head 8 is used to change the ejection condition of the cutting beam, control the area and size of the diffusion of the laser medium, and ensure the cutting quality. Each second laser head 15 is used to guide the laser medium onto the laser medium ejected by the first laser head 8, and then change the curvature of the laser medium ejected by the first laser head 8. By changing the curvature of the laser medium, the divergence angle of the reflected light beam is changed, thereby changing the focal position and realizing the function of automatic focusing. This can save a lot of time and improve the laser cutting efficiency. The laser medium ejected by the second laser head 15 can be refracted on the laser medium ejected by the first laser head 8.
