[0067] Please refer to Figures 1 to 9 In this application, a laser processing device 100 is proposed. In an embodiment of this application, the laser processing device 100 includes a mounting crossbeam 10, a laser processing head 20, a first driving mechanism 30, a support carrier 40, and two guide rail assemblies 50; the two guide rail assemblies 50 are relatively spaced in the X-axis direction on the support carrier 40 and both extend along the Y-axis direction; the mounting crossbeam 10 extends along the X-axis direction, and both ends are slidably mounted on the two guide rail assemblies 50 respectively; the laser processing head 20 is arranged on the mounting crossbeam 10; the first driving mechanism 30 includes a first driving member 31 and two first transmission components 33. The two first transmission components 33 are respectively arranged on the two guide rail assemblies 50, and the two first transmission components 33 are respectively connected to both ends of the mounting crossbeam 10; the first driving member 31 is arranged on the support carrier 40 and is connected to the two first transmission components 33. The first driving member 31 is used to drive the two first transmission components 33 to move so as to drive the mounting crossbeam 10 to move in the Y-axis direction.

[0068] The support carrier 40 can be used to provide a mounting position for mounting the guide rail assemblies 50, the first driving member 31, etc. At this time, the two guide rail assemblies 50 can be connected through the support carrier 40 to form an integral body, so as to improve the stability of this part of the mechanism, and further improve the stability of the movement of the first transmission component 33 mounted on the guide rail assembly 50. At the same time, it can also stably carry the first driving member 31 to improve the stability of the operation of the first driving member 31. In this way, under the stable operation of the first driving member 31 and the stable transmission of the first transmission component 33, it is convenient to realize the stable movement of the mounting crossbeam 10. Among them, the support carrier 40 can be a plate structure, and of course it can also be a seat structure or a frame structure. This application does not limit the structural type and shape of the support carrier 40.

[0069] The mounting crossbeam 10 can be used to provide a mounting position for mounting the laser processing head 20. Among them, when the laser processing equipment 100 is in a normal installation and use state, the X-axis direction and the Y-axis direction can be two horizontal directions, that is, they can be the length direction and the width direction of the laser processing equipment 100 respectively. The mounting crossbeam 10 can extend into a strip shape along the X-axis direction and be slidably mounted on two guide rail assemblies 50 at both ends, so as to enable the laser processing head 20 mounted on the mounting crossbeam 10 to perform mobile processing in the Y-axis direction.

[0070] The laser processing head 20 can be used to emit laser light to achieve laser processing of cutting or punching the workpiece. Among them, the laser processing head 20 can be fixedly mounted on the mounting crossbeam 10. Of course, the laser processing head 20 can also be movably mounted on the mounting crossbeam 10. As introduced below, the laser processing head 20 can be driven by the second driving mechanism 60 to move along the X-axis direction, so as to enable the laser processing head 20 to perform further mobile processing in the X-axis direction. Or, it can also be further included a third driving mechanism 70 as introduced below to drive the laser processing head 20 to move along the Z-axis direction perpendicular to the X-axis direction and the Y-axis direction (which can also be said to be the up and down direction, or the height direction of the laser processing equipment 100), so as to enable the laser processing head 20 to perform more diverse mobile processing in the Y-axis direction, X-axis direction and Z-axis direction.

[0071] The first driving mechanism 30 can be used to provide driving force to drive the mounting crossbeam 10 to move, and thus enable the laser processing head 20 mounted on the mounting crossbeam 10 to perform mobile processing. Among them, the first driving member 31 in the first driving mechanism 30 can be a motor, and of course it can also be a rotary cylinder, as long as it can provide power. The first transmission assembly 33 can be used to transmit the power of the first driving member 31 to the end of the mounting crossbeam 10, and thus enable the first driving member 31 to apply force to both ends of the mounting crossbeam 10, so that the mounting crossbeam 10 can be relatively evenly stressed. Among them, the first transmission assembly 33 can be a combination of the first driving wheel 331, the second driving wheel 631 and the first transmission belt 333 as introduced below, and of course it can also be a combination of a sprocket and a chain. The present application does not limit the specific type of the first transmission assembly 33.

[0072] According to the technical solution of the present application, when the laser processing equipment 100 is in use, the first driving mechanism 30 is configured as a combination of a first driving member 31 and two first transmission assemblies 33, and the two first transmission assemblies are respectively connected to the two ends of the mounting beam 10 in the X-axis direction. In this way, the first driving member 31 can drive the two ends of the mounting beam 10 through the two first transmission assemblies 33, and drive the mounting beam 10 to move along the Y-axis direction on the two guide rail assemblies 50. At this time, both opposite ends of the mounting beam 10 in the X-axis direction can be subjected to driving force, and the first driving member 31 is arranged on the support carrier 40. Compared with the first driving member 31 being arranged on the guide rail assembly 50, the first driving member 31 has better stability, and the driving force output to the two first transmission assemblies 33 is relatively uniform, so that the mounting beam 10 can achieve relatively uniform force at the opposite ends, which is conducive to improving the stability of the movement of the laser processing head 20 installed on the mounting beam 10, so that the laser processing equipment 100 can stably process the workpiece.

[0073] Please refer to Figure 6 In one embodiment of the present application, in the projection in the Y-axis direction, the first driving member 31 is located at or close to the middle position of the mounting beam 10.

[0074] In this embodiment, the first driving member 31 is arranged at the middle position of the mounting beam 10 or near the middle position of the mounting beam, so that the distances from the first driving member 31 to the two ends of the mounting beam 10 are equal; or approximately equal, for example, the difference is within a preset range value, and the preset range can be 5% or 10% of the length of the mounting beam 10 in the X-axis direction. At this time, it is beneficial to improve the uniformity of the force on the two ends of the mounting beam 10 in the X-axis direction, thereby improving the stability of the movement of the mounting beam 10, so as to improve the stability of the laser processing head 20 installed on the mounting beam 10 in processing the workpiece.

[0075] Please refer to Figure 7 and Figure 8 In one embodiment of the present application, the first driving member 31 has two coaxial and opposite output shafts 311 in the X-axis direction, and the two output shafts 311 are respectively connected to the two first transmission components 33.

[0076] In this embodiment, the first driving member 31 is directly a dual-axis motor having two output shafts 311, so that the connection position can be directly given through the two output shafts 311, facilitating the direct connection of the two first transmission components 33 on the opposite sides to the two output shafts 311. Of course, the present application is not limited to this. In other embodiments, the first driving member 31 may also have only one output shaft 311. At this time, in order to enable the first driving member 31 to still drive the first transmission components 33 on both sides relatively evenly, a driving shaft may be provided. The opposite ends of the driving shaft can be respectively connected to the first transmission components 33. At the same time, a driven gear can be provided in the middle of the driving shaft, and a driving gear can also be provided on the output shaft 311 of the first driving member 31, and the driving gear and the driven gear are meshed, so as to realize the relatively even driving of the two first transmission components 33 by the first driving member 31 with a single output shaft 311.

[0077] Please refer to Figures 6 to 9 , in an embodiment of the present application, the first transmission component 33 includes a first driving wheel 331, a first driven wheel 332, and a first transmission belt 333. The first driving wheel 331 is fixed on the guide rail assembly 50 and connected to the output shaft 311. The first driven wheel 332 is fixed on the guide rail assembly 50 and is spaced from the first driving wheel 331 in the Y-axis direction. The first transmission belt 333 is wound around the first driving wheel 331 and the first driven wheel 332, and the mounting cross beam 10 is connected to the first transmission belt 333.

[0078] In this embodiment, the first transmission component 33 is set to include a first driving wheel 331, a first driven wheel 332, and a first transmission belt 333, which can enable the first transmission component 33 to have a relatively large transmission distance, so as to realize that the laser processing head 20 can have a relatively large moving processing range in the Y-axis direction. At the same time, such a setting can also make the structure of the first transmission component 33 relatively simple, which is conducive to improving the convenience of manufacturing and installation.

[0079] Please refer to Figure 8 and Figure 9 , in an embodiment of the present application, the first transmission component 33 further includes a transmission shaft 334. The transmission shaft 334 extends along the X-axis direction. One end of the transmission shaft 334 is connected to the output shaft 311, and the other end is connected to the first driving wheel 331.

[0080] In this embodiment, the transmission shaft 334 facilitates access to the first driving wheel 331, thereby realizing the connection between the first driving wheel 331 and the corresponding output shaft 311. In this way, the first driving wheel 331 does not need to be set relatively long to realize its connection with the output shaft 311 on the first driving member 31, which is beneficial to reducing the volume of the first driving wheel 331 and improving the convenience of its manufacturing and installation. Of course, it should be noted that this application is not limited to this. In other embodiments, when the transmission shaft 334 is not provided, the first driving wheel 331 can be set relatively long in its axial direction so that one end of the first driving wheel 331 is connected to the corresponding output shaft 311 and the other end is used to wind the first transmission belt 333. In addition, the transmission shaft 334 can be connected to the output shaft 311 of the first driving member 31 through a coupling to improve the convenience and stability of the connection between the two.

[0081] Please refer to FIGS. 7 to Figure 9 In an embodiment of the present application, the guide rail assembly 50 includes a guide rail 51, a first support seat 53, and a second support seat 55. The guide rail 51 extends along the Y-axis direction. The first support seat 53 and the second support seat 55 are spaced along the Y-axis direction on the support carrier 40. The first driving wheel 331 is arranged on the first support seat 53, and the first driven wheel 332 is arranged on the second support seat 55; rollers 11 are provided at both ends of the mounting cross beam 10, and the rollers 11 are slidably mounted on the guide rail 51.

[0082] In this embodiment, the guide rail 51 can play a guiding role in the sliding of the mounting cross beam 10, which is beneficial to further improving the stability of the movement of the mounting cross beam 10, so that the laser processing head 20 mounted on the mounting cross beam 10 can perform stable processing. The further setting of the rollers 11 can reduce the friction force of the mounting cross beam 10 moving on the guide rail 51, which is beneficial to improving the smoothness of the mounting cross beam 10 moving on the guide rail 51 and reducing wear, thus being beneficial to improving the service life of the laser processing equipment 100. The settings of the first support seat 53 and the second support seat 55 can facilitate the installation positions for the first driving wheel 331 and the first driven wheel 332.

[0083] Please refer to Figure 6 、 Figure 9 as well as Figure 10 and Figure 11 In an embodiment of the present application, the guide rail assembly 50 further includes at least two guide rods 337. The at least two guide rods 337 are arranged on both sides of the guide rail 51 in the Z-axis direction. The guide rods 337 extend along the Y-axis direction. The Z-axis direction is perpendicular to the X-axis direction and the Y-axis direction; the number of the rollers 11 is multiple, and at least two rollers 11 are arranged opposite to each other in the Z-axis direction and respectively abut against one guide rod 337.

[0084] In this embodiment, by setting the guide rod 337 to abut against the roller 11, only the guide rod 337 can be made of a special wear-resistant material, and the guide rail 51 as a whole does not need to be made of a special wear-resistant material, which is conducive to reducing the manufacturing cost of the guide rail 51. Moreover, the structure of the guide rod 337 is relatively simple, and it is still located outside the guide rail 51, which can make the guide rod 337 convenient to process and ensure the processing accuracy, thereby facilitating the improvement of the guiding accuracy of the guide rail 51 to the installation beam 10, so as to further improve the stability of the movement of the installation beam 10. Furthermore, at least two rollers 11 are arranged oppositely in the Z-axis direction and abut against one guide rod 337 respectively, so that the installation beam 10 can have a limiting effect in the Z-axis direction through the abutment between the roller 11 and the two guide rods 337, thereby facilitating the improvement of the stability of the installation beam 10 sliding on the guide rail 51. Among them, the guide rod 337 can be embedded in the guide rail 51 to simplify its installation. The number of rollers 11 can be three or more, as long as at least two rollers 11 are arranged opposite to each other in the Z-axis direction and respectively abut against one guide rod 337. In addition, an annular limiting groove can be provided on the roller 11, so that the roller 11 abuts against the guide rod 337 through the limiting groove, which is conducive to further improving the stability of the abutment and cooperation between the two.

[0085] Please refer to Figure 9 In one embodiment of the present application, the guide rail 51 is provided with a mounting groove 51 a, the mounting groove 51 a is extended along the Y-axis direction, and the first transmission belt 333 is disposed in the mounting groove 51 a.

[0086] In this embodiment, by providing the mounting groove 51a, the first transmission belt 333 can be provided with an accommodation space, thereby facilitating the compactness of the distribution between the first transmission belt 333 and the guide rail 51, so as to reduce the overall volume of the first transmission assembly 33. At the same time, the mounting groove 51a can also play an isolation and protection role for the first transmission belt 333, thereby facilitating the reduction of the possibility of damage, so as to improve the service life of the first transmission belt 333. In addition, the mounting groove 51a also prevents the first transmission belt 333 from being exposed on the guide rail 51, thereby facilitating the improvement of the aesthetic appearance. Among them, the mounting groove 51a can be provided on the side of the guide rail 51 away from the mounting crossbeam 10, so as to avoid the laser processing head 20 from touching the first transmission belt 333 during operation, thereby affecting the transmission of the first transmission assembly 33. Of course, in other embodiments, the mounting groove 51a can also be provided on other sides of the guide rail 51.

[0087] Please refer to Figure 5 and Figure 9 In one embodiment of the present application, the second support seat 55 is slidably disposed in the mounting groove 51 a along the Y-axis direction and can be fixed relative to the guide rail 51 in a limited position.

[0088] In this embodiment, the second support base 55 is slidably arranged and can be limited and fixed relative to the guide rail 51. That is to say, the sliding position of the second support base 55 can be adjusted so as to adjust the tightness of the first transmission belt 333. Among them, an adjusting screw 340 can be passed through the front connecting beam 41 introduced below, and the adjusting screw 340 is threadedly connected to the second support base 55. Thus, when the adjusting screw 340 is rotated, since the second support base 55 is in threaded cooperation with the adjusting screw 340 and is limited in the installation groove 51a and cannot rotate, the sliding adjustment of the second support base 55 only in the Y-axis direction is realized.

Among them, the buffer pad 937 can be a silica gel pad or a rubber pad. In addition, the button 933 can also be further prepared from an elastic material to enable the button module 90 to have a triple elastic buffering effect and further improve the pressing feel.
