Description

Technical Field

[0001] This utility model relates to the field of laser cutting device technology, specifically to a laser cutting head with a built-in follower structure. Background Technology

[0002] With the development of science and technology, my country's manufacturing industry is facing a transformation towards high-end and intelligent manufacturing. As a basic processing technology, laser technology is increasingly penetrating all aspects of industrial production. Laser cutting is a technology that uses a high-power-density fiber laser beam to irradiate the material being cut, causing the irradiated part of the material to vaporize and form tiny holes. As the fiber laser beam moves, the holes are continuously formed to complete the cutting process.

[0003] In actual production and processing, since the profiles cannot be completely flat, there are usually uneven surfaces. Therefore, the laser cutting head needs to make corresponding avoidance or following according to the changes in the shape of the workpiece. Based on the information obtained by the sensor in real time, it is determined that the corresponding distance needs to be compensated. In order to achieve the compensation effect of the laser cutting head, the existing method is to install the laser cutting head on the X, Y and Z axis drive device of the machine tool for compensation.

[0004] However, in work scenarios where the profile cut surface is irregular, the distance between the laser head nozzle and the workpiece needs to be fixed, requiring frequent replenishment. Existing products replenish this by adding a unidirectional motion follower device to reduce the replenishment pressure on the machine tool's X, Y, and Z axis drive devices. However, since the follower device is set independently, the installation process is relatively complicated. The follower device needs to be installed between the laser head and the X, Y, and Z axis drive devices, resulting in an unstable coordination relationship, which is not conducive to improving the company's competitiveness.

It will be explicitly and implicitly understood by those skilled in the art that the embodiments described in this invention can be combined with other embodiments.

[0026] To enable those skilled in the art to better understand the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings.

[0027] like Figures 1-6 As shown, this utility model discloses a laser cutting head with a built-in follower structure, including a laser head body. The laser head body includes a built-in drive module 1, a collimation module 2, and a follower head module 3. The built-in drive module 1 includes a drive housing 11 and a follower drive assembly. The collimation module 2 is fixedly mounted on the drive housing 11, and the drive housing 11 is provided with a drive connection window. The follower head module 3 includes a follower head housing and a focusing assembly 33 disposed in the follower head housing. The two ends of the follower head housing are a telescopic end 31 and a light-emitting end 32, respectively. The collimation module 2 is provided with a telescopic cavity that cooperates with the telescopic end 31 at one end facing the follower head module 3. The telescopic end 31 is provided with a follower connector that cooperates with the follower drive assembly. The follower connector passes through the drive connection window and connects to the moving end of the follower drive assembly. The follower drive assembly can drive the telescopic end 31 to perform telescopic movement in the telescopic cavity.

[0028] With the built-in drive module 1, the follow-up drive component drives the follow-up head module 3 to perform telescopic movement, thereby compensating for the laser cutting head processing. This integrated design of the traditional follow-up device and laser head effectively simplifies the assembly process. Furthermore, this design makes the compensation of the laser cutting head by the follow-up drive component more stable, effectively improving the user experience and the company's competitiveness.

[0029] The follow-up drive assembly includes a drive motor 12 and a drive screw 13. The moving end of the drive motor 12 is connected to the drive screw 13. The follow-up connector includes a connecting block 34. The lower end of the connecting block 34 is provided with a threaded seat 35 that cooperates with the drive screw 13. The threaded seat 35 is sleeved on the drive screw 13. A linear guide is provided in the drive housing 11. The linear guide can limit the movement direction of the connecting block 34 in the drive connection window.

[0030] The drive motor 12 drives the drive screw 13 to rotate, causing the threaded seat 35 to move in tandem. Under the action of the linear guide, the connecting block 34 moves linearly back and forth in the drive connection window, thereby realizing the relative movement between the follower head module 3 and the collimation module 2.

[0031] The guide part is a linear guide rail 14 disposed inside the drive housing 11. A linear slider 36 that cooperates with the linear guide rail 14 is fixedly disposed on the threaded seat 35. The linear slider 36 is slidably connected to the linear guide rail 14.

[0032] The cooperation between the linear guide 14 and the linear slider 36 makes the movement of the threaded seat 35 relative to the drive screw 13 more stable.

[0033] There are two linear guide rails 14 and two linear sliders 36. The two linear sliders 36 are matched with the two linear guide rails 14 one by one. The two linear guide rails 14 are symmetrically arranged on both sides of the drive screw 13.

[0034] By setting up two linear guides 14, the stability of the follower head module 3's movement can be further improved.

[0035] The drive housing 11 is also provided with two screw mounting seats 15 that cooperate with the drive screw 13. The two ends of the drive screw 13 are respectively located in the two screw mounting seats 15, and the drive screw 13 and the screw mounting seats 15 are rotatably connected.

[0036] The screw mounting base 15 effectively improves the stability of the drive screw 13 rotation.

[0037] The telescopic cavity is provided with a follow-up scale observation window 21, and the telescopic end 31 is provided with a telescopic scale ruler 37 that cooperates with the follow-up scale observation window 21.

[0038] By combining the follow-up scale observation window 21 with the telescopic scale 37, the processing personnel can observe the compensation value of the follow-up head module 3 at all times.

[0039] The laser cutting head with built-in follower structure also includes a follower head telescopic folding cylinder 4, which is sleeved on the follower head housing. The two ends of the follower head telescopic folding cylinder 4 are connected to the collimation module 2 and the telescopic end 31, respectively.

[0040] By setting the follower head telescopic folding cylinder 4, the sealing between the telescopic end 31 and the telescopic cavity can be improved.

[0041] The laser cutting head with a built-in follow-up structure also includes a collision avoidance assembly 5. The collision avoidance assembly 5 includes a connecting mounting base 51, a mounting sensor plate 52, and at least two anti-detachment elastic tension members 53. The mounting sensor plate 52 is fixedly connected to the drive housing 11. The upper and lower ends of the connecting mounting base 51 and the mounting sensor plate 52 are respectively provided with mounting connection parts that correspond to the anti-detachment elastic tension members 53. The two ends of the anti-detachment elastic tension members 53 are respectively provided on the corresponding mounting connection parts of the connecting mounting base 51 and the mounting sensor plate 52. The two anti-detachment elastic tension members 53 are respectively provided on the upper and lower sides of the connecting mounting base 51 and the mounting sensor plate 52. The anti-detachment elastic tension members 53 can prevent the mounting sensor plate 52 from detaching from the connecting mounting base 51. The connecting mounting base 51 is provided with a plurality of proximity switch sensors 54, and the mounting sensor plate 52 is provided with a proximity protrusion 521. The proximity switch sensors 54 can cooperate with the proximity protrusion 521 to identify collision signals.

[0042] By setting the anti-collision component 5, the service life of the laser cutting head with the built-in follow-up structure can be effectively extended. When an impact occurs, the main body of the laser head will drive the mounting sensor plate 52 to move, changing the position between the mounting sensor plate 52 and the connecting mounting base 51. When the proximity switch sensor 54 detects the change in the position of the proximity protrusion 521, it determines that an impact has occurred and controls the product to stop working and issue an alarm.

[0043] The laser cutting head with built-in follow-up structure also includes an anti-collision telescopic folding cylinder 6, which is sleeved on the connecting mounting base 51 and the mounting sensor plate 52. The anti-collision telescopic folding cylinder 6 is connected to the connecting mounting base 51 and the mounting sensor plate 52 respectively. The anti-collision telescopic folding cylinder 6 can improve the sealing between the connecting mounting base 51 and the mounting sensor plate 52.

[0044] The collimation module 2 includes a collimation housing 22, a collimation lens lifting cylinder 23, and a focusing knob 24. The collimation housing 22 has a lifting motion cavity that cooperates with the collimation lens lifting cylinder 23. The collimation lens lifting cylinder 23 is provided with a focusing connector 25. The collimation housing 22 is provided with a focusing linear guide port 221. The focusing connector 25 is located in the focusing linear guide port 221. The focusing knob 24 is provided with a focusing spiral groove 241 on the side facing the focusing linear guide port 221. One end of the focusing connector 25 is located in the focusing spiral groove 241. The focusing knob 24 can drive the collimation lens lifting cylinder 23 to move up and down in the lifting motion cavity by rotating itself.

[0045] Through the cooperation between the focusing knob 24, the focusing connector 25, and the collimating lens lifting cylinder 23, when focusing is required, rotating the focusing knob 24 will cause the focusing spiral groove 241 of the focusing knob 24 to drive the focusing connector 25 to move linearly in the focusing linear guide port 221. Thus, the focusing connector 25 drives the collimating lens lifting cylinder 23 to move up and down in the lifting motion cavity, changing the distance between the collimating lens lifting cylinder 23 and the laser head body connected to the light source, thereby achieving the focusing effect.

[0046] The focusing assembly 33 includes a focusing mount, a focusing lens, a centering component, and a flexible adjustment support. The focusing mount has a mounting position that mates with the focusing lens, and the area of ​​the mounting position is larger than the area of ​​the focusing lens. The flexible adjustment support and the centering component are respectively located at both ends of the focusing lens. The focusing mount has a threaded hole that mates with the centering component, and the threaded hole connects to the mounting position. The centering component can push the focusing lens toward the flexible adjustment support by rotating itself.

[0047] By combining the centering component and the elastic adjustment support, the problem of the laser head body being connected to the light source and the light source emission angle not being perpendicular to the collimation module 2 can be effectively solved. This causes the parallel light emitted from the collimation module 2 to also tilt at a certain angle. By rotating the centering component, the position of the focusing lens in the mounting position is changed, ensuring that the focal point of the light emitted from the light-emitting end 32 is at the center position.

[0048] Both the follow-up head telescopic folding tube 4 and the anti-collision telescopic folding tube 6 are bellows covers, which effectively seal the parts.

[0049] As can be seen from the above, the beneficial effects of this utility model are: by adopting its mechanism, it can effectively solve the problems of the existing laser cutting head and follower device being relatively independent, with complex installation and unstable cooperation. By using this product structure, the collimation module 2 is fixedly set on the drive housing 11, and the follower drive component in the built-in drive module 1 drives the follower head module 3 to perform telescopic movement, thereby realizing compensation in the laser cutting head processing process. The traditional follower device and laser head are integrated into one design, which effectively simplifies the assembly process. Furthermore, through this design, the compensation of the laser cutting head by the follower drive component can be made more stable, effectively improving the user experience and the competitiveness of enterprises.

[0050] The specific embodiments described above are preferred embodiments of this utility model, and are not intended to limit the specific scope of this utility model. The scope of this utility model includes but is not limited to the specific embodiments described above. All equivalent changes made in accordance with this utility model are within the protection scope of this utility model.
