[0002] The laser processing machine focuses the laser light emitted from the laser into a high-power density laser beam through the optical path system. The laser beam irradiates the surface of the workpiece, causing the workpiece to reach the melting point or boiling point. At the same time, the high-pressure gas coaxial with the beam blows away the molten or vaporized metal. Laser cutting replaces the traditional mechanical knife with an invisible beam. It has the characteristics of high precision, fast cutting, no limitation on cutting pattern, automatic typesetting to save materials, smooth incision, low processing cost, etc. It will gradually improve or replace traditional metal cutting process equipment.

DETAILED DESCRIPTION

[0030] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. All other embodiments obtained by ordinary technicians in this field based on the embodiments of the present invention without making any creative efforts shall fall within the scope of protection of the present invention.

[0031] It should be noted that all directional indications in the embodiments of the present invention (such as up, down, left, right, front, back, etc.) are only used to explain the relative position relationship, movement status, etc. between the various components under a certain specific posture (as shown in the accompanying drawings). If the specific posture changes, the directional indication will also change accordingly.

[0032] It should also be noted that when an element is referred to as being "fixed on" or "disposed on" another element, it may be directly on the other element or there may be an intermediate element. When an element is referred to as being "connected to" another element, it may be directly connected to the other element or there may be an intermediate element.

[0033] In addition, the descriptions of "first", "second", etc. in the present invention are for descriptive purposes only and should not be understood as indicating or implying their relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features defined as "first" or "second" may explicitly or implicitly include at least one of such features. In addition, the technical solutions between the various embodiments can be combined with each other, but this must be based on the fact that they can be implemented by ordinary technicians in this field. When the combination of technical solutions is contradictory or cannot be implemented, it should be deemed that such combination of technical solutions does not exist and is not within the scope of protection required by the present invention.

[0034] like Figures 1 to 10 As shown, it is a laser component suitable for laser processing equipment according to an embodiment of the present invention, which is used to generate laser and process a workpiece to be processed.

[0035] See also Figures 1-6 As shown, the laser assembly 60 of an embodiment of the present invention includes a mounting frame 64, a laser processing head 61 and an angle adjustment mechanism 62. The angle adjustment mechanism 62 includes a rotating member 621 and an adjusting member 622. The rotating member 621 is rotatably mounted on the mounting frame 64. The laser processing head 61 is connected to the rotating member 621. The axis of the laser processing head 61 is perpendicular to the axis of the rotating member 621. The adjusting member 622 is connected to the rotating member 621 and is used to drive the rotating member 621 to rotate around its own axis to adjust the inclination angle of the laser processing head 61 relative to the workpiece to be processed.

[0036] Optionally, the laser processing head 61 includes a laser head and an optical fiber cutting head connected to the laser head.

[0037] During installation and use, the mounting bracket 64 is mounted on the Z-axis motion mechanism 40 of the laser processing equipment, and the axis of the rotating member 621 is parallel to the X-axis.

[0038] The laser assembly 60 of the embodiment of the present invention adjusts the inclination angle of the laser processing head 61 relative to the workpiece to be processed by setting an angle adjustment mechanism 62, so that the laser processing head 61 can be adjusted in all directions, so that the laser processing head 61 can improve the processing accuracy when processing workpieces with complex curved surfaces, thereby expanding the application range of the laser processing equipment; and the angle adjustment mechanism 62 has a simple structure and is easy to operate.

[0039] See also Figure 4-Figure 6As shown, exemplarily, in some embodiments, the angle adjustment mechanism 62 also includes a first fastener (not shown), the adjustment member 622 is disc-shaped, and multiple groups of first positioning portions are provided on the adjustment member 622, each group of first positioning portions includes at least two first positioning holes 6221, and multiple groups of second positioning portions are provided on the mounting frame 64, each group of second positioning portions includes at least two second positioning holes 641, and the first fastener is respectively adapted to the first positioning holes 6221 and the second positioning holes 641.

[0040] During the adjustment process, first remove the first fastener, then manually rotate the adjusting member 622 so that the inclination angle of the laser processing head 61 relative to the workpiece to be processed reaches a preset angle, stop rotating the adjusting member 622, and insert the first fastener through the first positioning hole 6221 into the second positioning hole 641 to complete the adjustment.

[0041] It should be noted that one or more first fasteners may be provided, as long as the adjusting member 622 and the mounting bracket 64 can be relatively fixed after the adjustment is completed.

[0042] Optionally, multiple groups of first positioning parts are evenly distributed with the center of the rotating part 621 as the center of the circle, and the two or more first positioning holes 6221 of each group of first positioning parts are distributed in a straight line, and the two or more first positioning holes 6221 are distributed from the direction close to the center of the circle to the direction away from the center of the circle. Multiple groups of second positioning parts are evenly distributed with the center of the rotating part 621 as the center of the circle, and the two or more second positioning holes 641 of each group of second positioning parts are distributed in an arc shape, and the two or more second positioning holes 641 are distributed from the direction close to the center of the circle to the direction away from the center of the circle. By reasonably setting the distribution pattern of the first positioning part, the first positioning hole 6221, the second positioning part and the second positioning hole 641, the adjustment range and adjustment accuracy of the adjusting part 622 can be widened, thereby improving the adjustment accuracy of the laser processing head 61.

[0043] Furthermore, the angle adjustment mechanism 62 also includes a second fastener (not shown in the figure), and a plurality of first waist-shaped grooves 6222 are provided on the adjusting member 622, and the plurality of first waist-shaped grooves 6222 are evenly distributed with the center of the rotating member 621 as the center of the circle, and a plurality of third positioning holes 648 are provided on the mounting frame 64, and the plurality of third positioning holes 648 are arranged one-to-one corresponding to the plurality of first waist-shaped grooves 6222, and the second fastener is respectively adapted to the first waist-shaped groove 6222 and the third positioning hole 648. By providing the first waist-shaped groove 6222 on the adjusting member 622, the third positioning hole 648 and the second fastener on the mounting frame 64, the adjusting member 622 can be positioned for the second time after the adjusting member 622 is rotated into place, which can further improve the connection stability.

[0044] Furthermore, a handle portion 6223 is provided on the adjusting member 622 . The handle portion 6223 enables the user to better grip the adjusting member 622 , making it more convenient to operate the adjusting member 622 .

[0045] Furthermore, in order to make the two ends of the rotating member 621 more balanced, the adjusting member 622 is arranged at one end of the rotating member 621, and a bearing cover 623 is provided at the other end of the rotating member 621. At the same time, the angle adjustment mechanism 62 also includes a second fastener (not shown in the figure), and a plurality of second waist-shaped grooves 6231 are provided on the bearing cover 623. The plurality of second waist-shaped grooves 6231 are evenly distributed with the center of the rotating member 621 as the center of the circle. A plurality of fourth positioning holes 649 are provided on the mounting frame 64. The plurality of fourth positioning holes 649 are arranged one-to-one corresponding to the plurality of second waist-shaped grooves 6231, and the second fasteners are respectively adapted to the second waist-shaped grooves 6231 and the fourth positioning holes 649.

[0046] In other embodiments, the adjusting member 622 is a driving motor, and the output shaft of the driving motor is connected to the rotating member 621 .

[0047] See also Figure 4-10 As shown, for example, in certain embodiments, the laser assembly 60 further includes a fine-tuning mechanism 63. The number of laser processing heads 61 is n, where n is an integer greater than 1. The number of fine-tuning mechanisms 63 is n-1, and each of the n-1 fine-tuning mechanisms 63 corresponds to each of the n-1 laser processing heads 61. The n-1 fine-tuning mechanisms 63 are connected to a rotating member 621, with one laser processing head 61 connected to the rotating member 621, and the remaining laser processing heads 61 are mounted on the corresponding fine-tuning mechanism 63. The angle adjustment mechanism 62 is used to drive the laser processing head 61 to swing to adjust the inclination angle of the laser processing head 61 relative to the workpiece to be processed. The fine-tuning mechanism 63 is used to drive the laser processing head 61 to move along the X-axis, Y-axis, and Z-axis, respectively. The laser processing equipment is provided with n laser processing heads 61, where n is an integer greater than 1, i.e., at least two laser processing heads 61 are provided. By providing two or more laser processing heads 61, more than two workpieces to be processed can be processed simultaneously, thereby improving work efficiency. Moreover, the laser processing equipment can further fine-tune the laser processing head 61 through the fine-tuning mechanism 63 after the angle adjustment mechanism 62 is adjusted, thereby avoiding the problem that the laser processing head 61 cannot process the workpiece to be processed more accurately due to the installation error of the laser processing head 61 or the installation error of the workpiece to be processed, thereby further improving the processing accuracy.

[0048] Understandably, the number of fine-tuning mechanisms 63 is one less than the number of laser processing heads 61. One laser processing head 61 may not be provided with a fine-tuning mechanism 63, while the remaining laser processing heads 61 are provided with a corresponding fine-tuning mechanism 63. The provision of the fine-tuning mechanisms 63 further improves the adjustment accuracy of the laser processing heads 61. During use, the angle adjustment mechanism 62 drives the rotation of the multiple laser processing heads 61, simultaneously adjusting the inclination angles of the multiple laser processing heads 61 relative to their corresponding workpieces. During adjustment, the angle adjustment mechanism 62 adjusts the angles of all laser processing heads 61, based on the requirements of the laser processing head 61 without the fine-tuning mechanism 63. Further fine-tuning of each laser processing head 61 is then determined based on requirements. When fine-tuning a laser processing head 61, the fine-tuning mechanism 63 adjusts the corresponding laser processing head 61.

[0049] It is understandable that each laser processing head 61 may also be provided with a corresponding fine-tuning mechanism 63 .

[0050] See also Figure 4-Figure 6 As shown, for example, in some embodiments, the mounting frame 64 includes a first vertical plate 642, a second vertical plate 643 and a rear side plate 647, the first vertical plate 642 and the second vertical plate 643 are connected by the rear side plate 647, the rotating member 621 includes a rotating cylinder 6211, a first rotating shaft 6212 and a second rotating shaft 6213, the front side of the rotating cylinder 6211 is open, the first rotating shaft 6212 and the second rotating shaft 6213 are respectively arranged on both sides of the rotating cylinder 6211, the first rotating shaft 6212 is rotatably mounted on the first vertical plate 642, the second rotating shaft 6213 is rotatably mounted on the second vertical plate 643, and the adjusting member 622 is located outside the mounting frame 64. side, and is connected to the first rotating shaft 6212 or the second rotating shaft 6213, more than two laser processing heads 61 are installed at intervals on the rotating cylinder 6211, and the laser processing heads 61 pass through the top and bottom of the rotating cylinder 6211 and are exposed outside the rotating cylinder 6211. By setting up more than two laser processing heads 61, more than two workpieces to be processed can be processed at the same time, thereby improving work efficiency; and by reasonably setting the structure of the mounting frame 64 and the rotating member 621, the adjusting member 622 can simultaneously adjust the inclination angle of more than two laser processing heads 61 relative to the corresponding workpieces to be processed, thereby improving operational convenience and improving integration.

[0051] In this embodiment, the fine-tuning mechanism 63 is installed on the rotating cylinder 6211, and the mechanism connected to the angle adjustment mechanism 62 is installed on the rotating cylinder 6211. During use, the rotating cylinder 6211 is driven to rotate by the adjustment member 622, thereby driving the multiple laser processing heads 61 to rotate.

[0052] During installation and use, the rear side plate 647 is installed on the Z-axis motion mechanism 40.

[0053] Specifically, the second positioning hole 641 and the third positioning hole 648 are both provided on the first vertical plate 642 , and the fourth positioning hole 649 is provided on the second vertical plate 643 .

[0054] Furthermore, the rotating member 621 also includes a rotating front plate 6214, which is arranged on the front side of the rotating cylinder 6211 and is detachably connected to the rotating cylinder 6211. By setting the front side plate 646, the rotating cylinder 6211 can be covered, which can reduce dust from entering the rotating cylinder 6211.

[0055] Furthermore, the mounting frame 64 also includes a top plate 644, a bottom plate 645 and a front side plate 646. The top plate 644 is provided with at least two first movable grooves 6441, and the bottom plate 645 is provided with at least two second movable grooves 6451. The first vertical plate 642, the second vertical plate 643, the top plate 644, the bottom plate 645, the front side plate 646 and the rear side plate 647 are enclosed to form the mounting frame 64. The two ends of the laser processing head 61 extend from the first movable groove 6441 and the second movable groove 6451 respectively. By arranging the top plate 644, the bottom plate 645 and the front side plate 646, the mounting frame 64 forms an enclosed structure, which can reduce dust from entering the interior of the mounting frame 64.

[0056] It can be understood that the number of the first movable grooves 6441 and the number of the second movable grooves 6451 are respectively the same as the number of the laser processing heads 61 .

[0057] In other embodiments, the number of the angle adjustment mechanisms 62 is the same as the number of the laser processing heads 61 , and each angle adjustment mechanism 62 adjusts a single laser processing head 61 .

[0058] See also Figures 4-10 As shown, exemplarily, in some embodiments, the fine-tuning mechanism 63 includes a first fine-tuning component 631, a second fine-tuning component 632 and a slide adapter plate 633.

The first fine-tuning component 631 is installed on the rotating cylinder 6211, and the second fine-tuning component 632 is arranged on the first fine-tuning component 631. The second fine-tuning component 632 is connected to the laser processing head 61 through the slide adapter plate 633. The first fine-tuning component 631 adopts a structure that can drive the laser processing head 61 to move along the X-axis and the Y-axis, which can improve the integration of the fine-tuning mechanism 63, reduce the occupied space of the fine-tuning mechanism 63, and reduce the weight of the fine-tuning mechanism 63, thereby reducing the load on the rotating part 621.

[0059] Optionally, the first fine-tuning assembly 631 includes a base 6311, a first slider 6312, a second slider 6313, a first adjustment rod 6314, a second adjustment rod 6315, a first positioning plate 6316, a second positioning plate 6317, a third fastener 6318, and a fourth fastener 6319.
