DETAILED DESCRIPTION

[0033] In order to facilitate the understanding of the present invention, the present invention will be described more comprehensively with reference to the accompanying drawings. The accompanying drawings show preferred embodiments of the present invention.

Therefore, the features defined as "first" and "second" may explicitly or implicitly include one or more of the features. In the description of the embodiments of the present utility model, the meaning of "multiple" is two or more, unless otherwise clearly and specifically defined.

[0036] In the embodiments of the present invention, unless otherwise clearly specified and limited, the terms "installed", "connected", "connected", "fixed" and the like should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, it can be the internal connection of two elements or the interaction relationship between two elements. For ordinary technicians in this field, the specific meanings of the above terms in the embodiments of the present invention can be understood according to specific circumstances.

[0037] like Figures 1 to 8 As shown, a laser double-head cutting machine 1 includes a frame 10 and a laser mechanism 20. The laser mechanism 20 includes a laser generator 21, a conversion component 22, two light guide components 23 and two laser heads 24. The laser generator 21 is arranged on the frame 10. The output port of the laser generator 21 is connected to the conversion component 22. The two light guide components 23 are both connected to the conversion component 22. The receiving ends of the two laser heads 24 are respectively connected to the two light guide components 23. The conversion component 22 is used to connect the laser generator 21 and one of the light guide components 23 so that one of the laser heads 24 emits a laser line.

[0038] It should be noted that the laser generator 21 is slidably disposed on the frame 10. For example, the laser generator 21 is disposed on the frame 10 through a slide rail so that the laser generator 21 can slide horizontally relative to the frame 10, and the output port of the laser generator 21 is connected to one side of the conversion component 22. For example, the output port of the laser emitter is connected to one side of the conversion component 22 through a connecting block 40, one end of the connecting block 40 clamps the output port of the laser generator 21, and the other end of the connecting block 40 is screwed to the conversion component 22 through a screw. When the laser generator 21 slides horizontally on the frame 10, the laser generator 21 drives the conversion component 22 to slide horizontally relative to the frame 10. Furthermore, the two light guide components 23 are respectively connected perpendicularly to the two sides of the output port of the laser generator 21 and the conversion component 22, so that the laser generator 21 and the two light guide components 23 form a T-shaped structure with the conversion component 22 as the origin. Furthermore, since the output port of the laser generator 21 is connected to one side of the conversion component 22, and the other two sides of the conversion component 22 are respectively connected to the two light guide components 23, the laser line emitted by the laser generator 21 will first enter the conversion component 22, and the laser line will be transformed by the conversion component 22 and then connected to one of the two light guide components 23. Furthermore, the ends of the two light guide components 23 away from the conversion component 22 are respectively connected to the receiving ends of the two laser heads 24, so that the laser line emitted by the laser generator 21 will enter one of the laser heads 24 after being transformed by the conversion component 22. In this way, when the workpiece needs to be cut at multiple positions, the laser generator 21 can switch the connection with the two light guide components 23 through the conversion component 22, so that the laser line is switched between the two laser heads 24, and the laser head 24 can cut at different positions of the workpiece.

[0039] like Figures 1 to 3 As shown, in one embodiment, the conversion component 22 includes a motor 221, a hollow block 222 and a conversion mirror 223, the hollow block 222 is connected to the output port of the laser generator 21, the motor 221 is arranged on the hollow block 222, the conversion mirror 223 is rotatably arranged in the hollow block 222, and the conversion mirror is connected to the output shaft of the motor 221.

[0040] It should be noted that the motor 221 is disposed on the hollow block 222, the output shaft of the motor 221 is inserted into the hollow, the change mirror 223 is rotatably disposed in the hollow block 222, and one end of the change mirror 223 is connected to the output shaft of the motor 221, so that the motor 221 can drive the change mirror 223 to rotate in the hollow block 222. Further, the hollow block 222 is connected to the output port of the laser generator 21, so that the laser line emitted by the laser generator 21 can be irradiated on the change mirror 223 in the hollow block 222, so that when the motor 221 drives the change mirror 223 to rotate, the change mirror 223 can reflect the laser line into the light guide assembly 23.

[0041] like Figures 3 to 5 As shown, in one embodiment, three light beam channels are opened in the hollow block 222, and the transformation mirror 223 is located at the intersection of the three light beam channels.

[0042] It should be noted that three beam channels are provided in the hollow block 222, and the three beam channels on the hollow block 222 are respectively connected to the output port of the laser generator 21 and the two light guide components 23, so that the laser generator 21 and the two light guide components 23 form a T-shaped three-way structure with the hollow block 222 as the origin. For the convenience of further description, the two light guide components 23 are respectively defined as the first light guide component 232 and the second light guide component 233, the first light guide component 232 is located on the left side of the hollow block 222, and the second light guide component is located on the right side of the hollow block 222. Further, since the laser generator 21 and the two light guide components 23 form a T-shaped three-way structure with the hollow block 222 as the origin, the laser generator 21 can be connected to the first light guide component 232, and the laser generator 21 can also be connected to the second light guide component 233, so that the laser line emitted by the laser generator 21 can enter the first light guide component 232, and the laser line emitted by the laser generator 21 can also enter the second light guide component 233. Furthermore, the conversion mirror 223 is located at the intersection of the three light beam channels, and the conversion mirror 223 is connected to the output shaft of the motor 221. When the laser line emitted by the laser generator 21 enters the hollow block 222 and irradiates the conversion mirror 223, the motor 221 drives the conversion mirror 223 to rotate in the hollow block 222, so that the laser line is reflected into the first light guide component 232 or the second light guide component 233. For example, when the motor 221 drives the conversion mirror 223 to rotate 90 degrees in the forward direction, the laser line is reflected into the first light guide component 232. When the motor 221 drives the conversion mirror 223 to rotate 90 degrees in the reverse direction, the laser line is reflected into the second light guide component 233. Since the first light guide component 232 and the second light guide component 233 are respectively connected to the laser head 24, when the motor 221 drives the change mirror 223 to rotate 90 degrees forward and backward, the laser line can be emitted alternately back and forth between the two laser heads 24. In this way, when the workpiece needs to be cut at multiple positions, the motor 221 drives the change mirror 223 to rotate 90 degrees forward and backward, so that after the laser head 24 cuts one position on the workpiece, it can be switched to another laser head 24 to cut another position on the workpiece.

[0043] like Figure 1 to Figure 2 , Figure 6 , Figure 8As shown, in one embodiment, the light guide assembly 23 includes a telescopic member 231 and a light guide tube 234, one end of the light guide tube 234 is connected to the hollow block 222 so that the light guide tube 234 is connected to one of the light beam channels, the other end of the light guide tube 234 is connected to the telescopic member 231, and the end of the telescopic member 231 away from the light guide tube 234 is connected to the receiving end of the laser head 24.

[0044] It should be noted that one end of the light guide 234 is connected to the hollow block 222, and the other end of the light guide 234 is connected to the telescopic member 231. For example, the light guide 234 is connected to the hollow block 222 and the telescopic member 231 through the connecting block 40, so that the telescopic tube 2312 is connected to one of the beam channels. Further, the end of the telescopic member 231 away from the light guide 234 is connected to the receiving end of the laser head 24, so that the laser head 24 is connected to one of the beam channels. When the motor 221 drives the conversion mirror 223 to rotate forward 90 degrees, the laser line enters the laser head 24 through one of the beam channels, so that one of the laser heads 24 can cut one of the positions on the workpiece. Further, when the motor 221 drives the conversion mirror 223 to rotate backward 90 degrees, the laser line enters another laser head 24 through another beam channel, so that another laser head 24 can cut another position on the workpiece.

[0045] like Figure 1 to Figure 2 , Figure 6 , Figure 8 As shown, in one embodiment, the telescopic member 231 includes a cylinder 2311, a telescopic tube 2312 and two steering blocks 2313, the two steering blocks 2313 are respectively arranged at both ends of the telescopic tube 2312, and one of the two steering blocks 2313 is connected to the light guide tube 234, and the other of the two steering blocks 2313 is connected to the laser head 24, the cylinder 2311 is arranged on one of the steering blocks 2313, and the output end of the cylinder 2311 is connected to the other steering block 2313.

[0046] It should be noted that the two steering blocks 2313 are respectively arranged at the two ends of the telescopic tube 2312. For example, the steering block 2313 and the telescopic tube 2312 are also fixedly connected through the connecting block 40, and one of the two steering blocks 2313 is connected to the end of the light guide tube 234 away from the hollow block 222, and the other of the two steering blocks 2313 is connected to the laser head 24, so that the telescopic tube 2312 is connected to the light beam channel of the light guide tube 234. Further, two light beam channels are provided in each steering block 2313, and the two light beam channels are distributed in a 90-degree right angle shape, so that the telescopic tube 2312 and the light guide tube 234 are connected at 90 degrees. Further, a reflector 2314 is provided at the angle position of the light beam channel, and the angle between the reflector 2314 and one of the light beam channels is 45 degrees. When the laser generator 21 emits a laser line, the laser line in the light guide tube 234 is reflected into the telescopic tube 2312. Furthermore, the cylinder 2311 is arranged on one of the steering blocks 2313, and the output end of the cylinder 2311 is connected to the other steering block 2313. When the cylinder 2311 moves, the two steering blocks 2313 are moved closer to or away from each other. Since one of the two steering blocks 2313 is connected to the light guide tube 234, and the other of the two steering blocks 2313 is connected to the laser head 24, the cylinder 2311 drives the telescopic tube 2312 to stretch or contract, thereby causing the cylinder 2311 to drive the laser head 24 to move up or down relative to the light guide tube 234.

[0047] like Figures 6 to 8 As shown, in one embodiment, the telescopic tube 2312 includes an outer tube 23121 and an inner tube 23122, the outer tube 23121 is disposed on one of the two steering blocks 2313, the inner tube 23122 is disposed on the other of the two steering blocks 2313, and the outer tube 23121 and the inner tube 23122 are sleeved.

[0048] It should be noted that at least one longitudinal groove 231213 is provided on the inner wall of the outer tube 23121, and the groove 231213 extends from one end of the inner wall of the outer tube 23121 to the other end, and at least one ridge 231224 is provided on the outer wall of the inner tube 23122, and the ridge 231224 extends from one end of the outer wall of the inner tube 23122 to the other end. Furthermore, the diameter of the outer tube 23121 is larger than the diameter of the inner tube 23122, so that the outer tube 23121 and the inner tube 23122 are socketed, so that the ridge 231224 and the groove 231213 are adapted to slide, and the outer tube 23121 and the inner tube 23122 can slide against each other. Further, the outer tube 23121 is arranged on one of the two steering blocks 2313, for example, the outer tube 23121 is also connected to one of the steering blocks 2313 through the connecting block 40, and the inner tube 23122 is arranged on the other of the two steering blocks 2313, for example, the inner tube 23122 is also connected to the other steering block 2313 through the connecting block 40. Furthermore, one of the two steering blocks 2313 is connected to the cylinder 2311, and the other of the two steering blocks 2313 is connected to the output end of the cylinder 2311. When the cylinder 2311 moves, the cylinder 2311 drives the two steering blocks 2313 to move closer to or farther from each other. Since the two steering blocks 2313 are respectively connected to the outer tube 23121 and the inner tube 23122, and the outer tube 23121 and the inner tube 23122 are sleeved, the cylinder 2311 drives the outer tube 23121 and the inner tube 23122 to slide away from or closer to each other, thereby causing the cylinder 2311 to drive the telescopic tube 2312 to stretch or contract. In this way, when the cylinder 2311 moves, it can drive the laser head 24 to move up or down, so that the laser head 24 can be adjusted according to the cutting height of different workpieces to achieve better cutting quality.

[0049] like Figure 1 , Figures 9 and 10 As shown, in one embodiment, the alternating mechanism 30 includes an alternating component 31, a support frame 32 and two workbenches 33. The alternating component 31 is arranged on the frame 10, the support frame 32 is arranged on the frame 10, one of the two workbenches 33 is slidably arranged on the frame 10, and the other of the two workbenches 33 is slidably arranged on the support frame 32 so that the two workbenches 33 have a height difference, and the two workbenches 33 are both connected to the alternating component 31 so that the alternating component 31 drives the two workbenches 33 to slide alternately.

[0050] It should be noted that the two workbenches 33 are used to support and fix the workpiece, so that the laser head 24 can process the workpiece. The support frame 32 is arranged on the frame 10. In one embodiment, there are two support frames 32. Further, for the convenience of description, the two workbenches 33 are respectively defined as an upper workbench 331 and a lower workbench 332. The two support frames 32 are respectively connected to the two ends of the upper workbench 331 in a sliding manner. The upper workbench 331 is connected to the support frame 32 in a sliding manner through a slide rail, and the lower workbench 332 is connected to the frame 10 in a sliding manner through a slide rail, so that the height of the upper workbench 331 is greater than the height of the lower workbench 332, so that the two workbenches 33 can slide alternately relative to the frame 10. Further, the alternating component 31 is arranged on the frame 10, and the upper workbench 331 and the lower workbench 332 are both connected to the alternating component 31, so that the alternating component 31 drives the upper workbench 331 and the lower workbench 332 to slide alternately relative to the frame 10. When the workpiece on the upper workbench 331 completes the cutting process, the alternating assembly 31 can drive the upper workbench 331 to slide, so that the workpiece on the upper workbench 331 that has been processed is moved out of the cutting area, and at the same time, the alternating assembly 31 drives the lower workbench 332 to slide, so that the unprocessed workpiece on the lower workbench 332 is moved to the cutting area. In this way, after the laser head 24 completes the cutting action of one workpiece, it can quickly start the cutting action of the next workpiece, so as to improve the cutting efficiency.

[0051] like Figures 9 and 10 As shown, in one embodiment, the alternating component 31 includes an alternating motor 311, a belt 312 and two transmission wheels 313, the alternating motor 311 is disposed on the frame 10, one of the transmission wheels 313 is disposed on the output end of the alternating motor 311, and the other transmission wheel 313 is rotatably disposed on the frame 10, the belt 312 is respectively sleeved on the two transmission wheels 313, and the belt 312 is connected to the two workbenches 33.

[0052] It should be noted that the alternating motor 311 is arranged on the frame 10, wherein one transmission wheel 313 is arranged on the output end of the alternating motor 311, and the other transmission wheel 313 is rotatably arranged on the frame 10. For example, the other transmission wheel 313 is rotatably arranged on the frame 10 through a bearing, and there is a gap between the two transmission wheels 313. Furthermore, the belt 312 is respectively sleeved on the two transmission wheels 313, and the belt 312 is connected to the two workbenches 33. In this way, when the alternating motor 311 drives the belt 312 wheel to rotate, the belt 312 wheel drives the two workbenches 33 to slide alternately.

[0053] like Figures 9 and 10 As shown, in one embodiment, the alternating assembly 31 further includes two fixing blocks 314 , the two fixing blocks 314 are disposed on the belt 312 , and the two fixing blocks 314 are respectively connected to the two workbenches 33 .

[0054] It should be noted that the two fixed blocks 314 are arranged on the belt 312, and the two fixed blocks 314 are respectively connected to the two workbenches 33, so that when the alternating motor 311 drives the belt 312 to rotate, the two fixed blocks 314 can also move with the belt 312, thereby allowing the alternating motor 311 to drive the two workbenches 33 to slide alternately.

[0055] The above-mentioned embodiments only express several implementation methods of the utility model, and the descriptions thereof are relatively specific and detailed, but they cannot be understood as limiting the scope of the utility model patent. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the utility model, and these all belong to the protection scope of the utility model. Therefore, the protection scope of the utility model patent shall be based on the attached claims.
