In addition, the technical solutions between the various embodiments can be combined with each other, but it must be based on the ability of ordinary technicians in this field to implement. 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 this application.

[0051] Please refer to Figures 1 to 4 ,as well as Fig.10 The present application provides a laser processing device 100, which includes a housing 10, a laser head 30 and an air flow driving member 40. The housing 10 is provided with a processing chamber 11 and an air inlet 12 and an air outlet 13 communicating with the processing chamber 11; the laser head 30 is disposed in the processing chamber 11; the air flow driving member 40 is disposed in the housing 10, and is used to drive the external air flow to enter the processing chamber 11 from the air inlet 12 and be discharged from the air outlet 13.

[0052] The housing 10 can be used to form a processing chamber 11, so that the required processing space can be provided for the laser head 30 after the laser head 30 is installed. Among them, the housing 10 can be a square structure (including a rectangular parallelepiped and a cube), and of course it can also be a circular structure. The specific shape of the housing 10 is not limited in this application. The processing chamber 11 can be adaptively set according to the shape of the housing 10. For example, when the housing 10 is set in a square structure, the processing chamber 11 can also be set in a square structure, so that the wall thickness of each part of the housing 10 can be set more uniformly to improve the convenience of its manufacture. Further, the air inlet 12 provided on the housing 10 can be used for the external airflow to enter the processing chamber 11, and the exhaust port 13 can be used for the exhaust of the airflow in the processing chamber 11, so as to realize the ventilation of the airflow in the processing chamber 11. Among them, the number of the air inlet 12 can be one, and of course it can also be at least two, and the air inlet 12 can be a square hole, a circular hole, a triangular hole, an elliptical hole or a bar hole or any other shape hole. Similarly, the number of the exhaust port 13 may be one, or at least two, and the exhaust port 13 may be a square hole, a circular hole, a triangular hole, an elliptical hole, a strip hole, or any other shape. In addition, the air inlet 12 and the exhaust port 13 may be disposed on any surface of the housing 10, and the air inlet 12 and the exhaust port 13 may be disposed on the same side surface of the housing 10, or on surfaces of different sides.

[0053] The laser head 30 can be used to emit laser light to achieve cutting, drilling or engraving of the workpiece, and can be specifically configured adaptively according to the type of processing actually required. Furthermore, in order to achieve processing of different parts of the workpiece, the laser processing equipment 100 can also include a driving mechanism, which is arranged in the processing chamber 11 to drive the laser head 30 to move horizontally and / or up and down. The driving mechanism can be a combination of a motor and a screw rod, and of course the driving mechanism can also be a combination of a motor, a belt and a pulley. The present application does not limit the specific type of the driving mechanism, and it is sufficient to drive the laser head 30.

[0054] The airflow driving member 40 can be used to provide power. The airflow driving member 40 can be arranged between the air inlet 12 and the exhaust port 13 to drive the airflow to form a flow path from the air inlet 12 into the processing chamber 11 and discharged from the exhaust port 13. The airflow driving member 40 can be a fan or a blower. In addition, the airflow driving member 40 can be an exhaust action, in which case the airflow driving member 40 can be connected to the exhaust port 13. Of course, the airflow driving member 40 can also be a blowing action, in which case the airflow driving member 40 can be connected to the air inlet 12. Therefore, the present application does not limit the specific type of the airflow driving member 40, and it is sufficient to ensure that the airflow can be driven to form a flow path from the air inlet 12 into the processing chamber 11 and discharged from the exhaust port 13. In addition, the airflow driving member 40 can be arranged on the inner side of the housing 10, for example: in the processing chamber 11, to improve the compactness of the airflow driving member 40 on the housing 10, and at the same time, the housing 10 is used to provide isolation and protection for the airflow driving member 40 and improve the aesthetic appearance of the housing. Of course, the airflow driving member 40 may also be disposed on the outside of the housing 10 , or on the housing 10 .

[0055] When the laser processing device 100 of the technical solution of the present application is in use, the airflow driving member 40 can drive the airflow to form a flow path from the air inlet 12 into the processing chamber 11, and then be discharged from the exhaust port 13. At this time, the smoke generated by the laser head 30 located in the processing chamber 11 when processing the workpiece can be discharged from the exhaust port 13 along with the airflow, so that the smoke generated by the laser processing device 100 during processing is discharged in time, which can reduce the obstruction of the smoke to the laser emitted by the laser head 30, thereby facilitating the improvement of the processing efficiency of the laser processing device 100.

[0056] In addition, the housing 10 has an isolating and blocking effect on the smoke generated by the laser head 30 when processing the workpiece, so that it is discharged from the exhaust port 13, thereby realizing the directional discharge of the smoke. In addition, since the laser head 30 is located in the processing chamber 11 of the housing 10, the housing 10 can also shield the laser emitted by the laser head 30, thereby reducing the possibility of the laser emitted by the laser head 30 causing harm to the human body, which is conducive to improving the safety of the use of the laser processing equipment 100.

[0057] Please refer to Figures 4 to 9 In one embodiment of the present application, the housing 10 is further provided with an air passage 14 and an air port 15 , the air inlet 12 is connected to the air passage 14 , and the air port 15 is connected to the air passage 14 and the processing chamber 11 .

[0058] In this embodiment, the air passage 14 is a passage between the air inlet 12 and the air passage 15, so that the external airflow enters the air passage 14 first after passing through the air inlet 12, and then enters the processing chamber 11 from the air passage 15. At this time, due to the setting of the air passage 14, even when the laser emitted by the laser head 30 is transmitted through the air passage 15, it still needs to pass through the air passage 14 to reach the air inlet 12, which is conducive to reducing the possibility of the laser emitted by the laser head 30 being emitted from the air inlet 12, so as to further improve the safety of the use of the laser processing equipment 100. Among them, the air passage 14 can be set in a linear strip shape, of course, it can also be set in an L shape, or in an S shape. The present application does not limit the shape of the air passage 14. In addition, the air passage 14 can be one, or of course, it can also be at least two. When there are at least two air passages 14, the at least two air passages 14 can be set on the same side of the housing 10, or of course, they can be set on different sides of the housing 10. In addition, the air port 15 can be a hole of any shape such as a semicircular hole, a circular hole, a square hole, a triangular hole, an elliptical hole or a strip hole. The air passage 14 can be arranged near the bottom of the housing 10, or can be located outside the processing bottom plate to avoid the air passage 14 limiting the size of the processing area.

[0059] Please refer to Figures 7 to 9 In one embodiment of the present application, the air passage 14 is arranged in a strip shape, and the number of air inlets 12 and air outlets 15 is multiple, and they are arranged in sequence and spaced apart along the extension direction of the air passage 14; in the extension direction perpendicular to the air passage 14, the multiple air inlets 12 and the multiple air outlets 15 are staggered.

[0060] In this embodiment, when the laser processing equipment 100 is in normal use, it can have a front-to-back direction and a left-to-right direction. The front-to-back direction can correspond to the width direction of the laser processing equipment 100, and the left-to-right direction can correspond to the length direction of the laser processing equipment 100. At this time, the air passage 14 can be extended into a strip along the front-to-back direction and / or the left-to-right direction, so that the air inlet 12 and the air outlet 15 can be arranged in multiple numbers along the extension direction of the air passage 14, which is conducive to increasing the air intake of the air inlet 12, so as to form a larger airflow and improve the subsequent effect of taking away the smoke in the processing chamber 11. Further, in the extension direction perpendicular to the air passage 14, each air inlet 12 and an air outlet 15 are staggered, for example: each air inlet 12 is located between two adjacent air outlets 15. At this time, even after the laser emitted by the laser head 30 enters the gas passage 14 through the gas port 15, the gas inlet 12 and the gas port 15 are staggered, so that the laser is difficult to be further emitted from the gas inlet 12, thereby further improving the anti-leakage effect of the laser and further improving the safety of the laser processing equipment 100. The gas inlet 12 and the gas port 15 can be completely staggered, or they can overlap partially.

[0061] Please refer to Figure 8 and Fig. 9 In one embodiment of the present application, the plurality of air inlets 12 and the plurality of air outlets 15 are respectively disposed on two adjacent channel walls of the air passage 14 .

[0062] In this embodiment, the air inlet 12 and the air outlet 15 are respectively arranged on two adjacent channel walls of the air passage 14, so that even if the laser enters the air passage 14 from the air outlet 15, it still needs to make a further turn before it can reach the air inlet 12, which is conducive to further improving the anti-leakage effect of the laser, so as to further improve the safety of the use of the laser processing equipment 100. Of course, it should be noted that the present application is not limited to this, and in other embodiments, the air inlet 12 and the air outlet 15 can also be respectively arranged on two opposite channel walls of the air passage 14.

[0063] Please refer to Figure 1 and Figure 2 ,as well as Figures 4 to 9In one embodiment of the present application, the number of the air passages 14 is at least two, and the at least two air passages 14 include a first air passage 141 and a second air passage 142; the first air passage 141 extends along the front-to-back direction, and the second air passage 142 extends along the left-to-right direction; the multiple air inlets 12 include a first air inlet 121 and a second air inlet 122, the first air inlet 121 is connected to the first air passage 141, and the second air inlet 122 is connected to the second air passage 142; the multiple air passages 15 include a first air passage 151 and a second air passage 152, the first air passage 151 is connected to the first air passage 141, and the second air passage 152 is connected to the second air passage 142.

[0064] In this embodiment, by extending the first air passage 141 in the front-to-back direction and the second air passage 141 in the second direction, part of the air inlet 12 and part of the air passage 15, that is, the first air inlet 121 and the first air passage 151, can be arranged in sequence in the front-to-back direction; and part of the air inlet 12 and part of the air passage 15, that is, the second air inlet 122 and the second air passage 152 can be arranged in sequence in the left-right direction, thereby realizing that the laser processing equipment 100 can take in air on at least two sides of the housing 10 to form a larger airflow and improve the subsequent effect of taking away the smoke in the processing chamber 11. Among them, the number of the first air passage 141 can be one, and of course it can also be two or more. Similarly, the number of the second air passage 142 can also be one, and of course it can also be more. In addition, the first air passage 141 and the second air passage 143 can be isolated from each other, and of course they can also be connected.

[0065] Please refer to Figure 1 and Figure 2 ,as well as Figures 4 to 9 In one embodiment of the present application, the first air passage 141 is close to the left or right side of the housing 10 , the second air passage 142 is close to the front side of the housing 10 , and the exhaust port 13 is located at the rear side of the housing 10 and close to the first air passage 141 .

[0066] In this embodiment, the first air passage 141 and the second air passage 142 are respectively arranged at the left or right edge and the front and rear edges of the housing 10, so that the laser processing device 100 can take in air from the edge of the housing 10, so that the subsequent airflow can better fill the processing chamber 11 and improve the effect of taking away the smoke in the processing chamber, while avoiding the first air passage 141 and the second air passage 142 from affecting the processing format of the laser processing device 100. Further, the exhaust port 13 is arranged at the rear side of the housing 10 and is arranged close to the first air passage 141, for example: the first air passage 141 is arranged on the left side of the housing 10, and the exhaust port 13 is close to the left side of the housing 10, so that the laser processing device 100 can take in air from the adjacent side and the opposite side of the exhaust port 13, which is conducive to further filling the processing chamber 11 with airflow. At the same time, since the first air passage 141 and the exhaust port 13 are relatively close, the airflow effect is better. In addition, the exhaust port 13 is arranged near one of the left side and the right side of the housing 10, which can also facilitate the avoidance of the control board and the power module and other mechanisms installed on the rear side of the housing 10. For example, when the exhaust port 13 is close to the left side of the housing 10, the control board and the power module and other mechanisms of the laser processing equipment 100 can be close to the right side of the housing 10. In addition, the exhaust port 13 is arranged on the rear side of the housing 10, for example, as the rear back surface 10d described below, so that the exhaust port 13 is not easy to be observed, which is conducive to improving the aesthetic appearance of the housing 10. At the same time, since it is usually away from the side where the personnel are, even if the laser leaks at the exhaust port 13, it is still not easy to cause harm to outsiders.

[0067] Please refer to Figure 1 and Figure 2 ,as well as Figures 4 to 9 In one embodiment of the present application, the air inlet 15 connected to the first air passage 141 is a circular hole, and the air inlet 15 connected to the second air passage 141 is a strip hole.

[0068] The air inlet 12 connected to the first air passage 141, that is, the first air inlet 121 described above, can be set as a circular hole to improve the convenience of its processing and forming. Since the second air passage 142 is relatively far from the exhaust port 13, in order to ensure the flow effect of the airflow, the air inlet 12 connected to the second air passage 142, that is, the first air inlet 122 described above, can be set as a strip hole to increase the air passage area, and at the same time, the second air inlet 122 can also be relatively regular, and the space on the front side of the housing 10 in the left and right directions can be fully utilized, thereby improving the convenience of processing and setting the second air inlet 122.

[0069] Please refer to Figures 5 to 8In one embodiment of the present application, the first air passage 141 may include a channel top wall 141a and a first side-passing side wall 141b connected to each other, and the first side-passing side wall 141b intersects the left-right direction of the channel top wall 141a; the air port 15 connected to the first air passage 141, that is, the first air port 151 may penetrate the channel top wall 141a and the first side-passing side wall 141b to be connected to the processing chamber 11. At this time, the first air port 151 forms an airflow that flows obliquely upward, so that the airflow covers the opposite side of the first air port 151, so that the airflow covers the processing chamber 11 in the left-right direction, which is conducive to further improving the filling effect of the airflow on the processing chamber 11. For example: when the first air port 151 is set on the left side of the housing 10, the first air port 151 can form an airflow that flows toward the upper right. The projection of the first air passage 151 in the up-down direction may be semicircular, so as to form an airflow that meets the required flow direction, and at the same time make the shape of the first air passage 151 more regular to improve the convenience of processing.

[0070] Please refer to Figures 5 to 7 ,as well as Fig. 9 In one embodiment of the present application, the second gas passage 142 includes a second passage side wall 142 a facing the rear side of the housing 10 , and the gas port 15 connected to the second gas passage 142 passes through the second passage side wall 142 a to connect to the processing chamber 11 .

[0071] In this embodiment, since the second air passage 142 and the plurality of air ports 152 connected to the second air passage 142, that is, the second air ports 15 described above, are sequentially arranged along the left-right direction, the processing chamber 11 can be well covered in the left-right direction. Therefore, the plurality of second air ports 152 can be arranged toward the rear side of the housing 10. In order to improve the convenience of processing and forming the second air ports 152, the air ports 152 connected to the second air passage 142, that is, the second air ports 152, can be arranged as circular holes.

[0072] Please refer to Figure 2 ,as well as Figures 5 to 9 In one embodiment of the present application, the housing 10 includes a main housing 16 and a cover 17, the main housing 16 is provided with a connecting port 161; the cover 17 covers the connecting port 161; the air inlet 12, the air passage 14 and the air outlet 15 are all provided on the cover 17, and the exhaust port 13 is provided on the main housing 16.

[0073] In this embodiment, the housing 10 is split into a main housing 16 and a cover 17, so that the two can be manufactured independently first and then assembled together. At this time, the structure of the main housing 16 and the cover 17 can be simpler than the overall structure, which is conducive to improving the convenience of manufacturing the two. In particular, the independent cover 17 is more conducive to improving the convenience of forming the air inlet 12, the air passage 14 and the exhaust port 13. Further, in order to improve the convenience of connecting the cover 17 and the main housing 16, the cover 17 can be connected by screws to simplify the assembly process while ensuring the stability of the connection between the two. Among them, the cover 17 can be enclosed with the main housing 16 to form a processing chamber 11. Of course, the processing chamber 11 can also be completely set on the main housing 16. In addition, when there are at least two air passages 14 as described above, there can also be at least two cover 17, and one air passage 14 is set on one cover 17. For example, when the at least two air passages 14 include the first air passage 141 and the second air passage 142 as described above, the first air passage 141 may be provided on one cover 17 , and the second air passage 142 may be provided on another cover 17 .

[0074] Please refer to Figure 1 and Figure 4 In one embodiment of the present application, the housing 10 is provided with a take-in / take-out port 163 communicating with the processing chamber 11 , and the housing 10 further includes a cover 18 movably mounted on the take-in / take-out port 163 so as to be able to open and close the take-in / take-out port 163 .

[0075] In this embodiment, the workpiece to be processed can be conveniently placed into the processing chamber 11 through the access opening 163, and the workpiece after processing can be taken out from the processing chamber 11. The cover 18 can play a protective role and improve the processing safety. Further, a cover 18 is provided at the access opening 163. The cover 18 can be transparent or translucent, so that it is convenient for outsiders to observe the processing situation in the processing chamber 11. Among them, the cover 18 can be directly placed on the housing 10, that is, the cover 18 and the housing 10 can be directly removed and covered. Of course, the cover 18 can also be rotatably connected to the housing 10, so that the cover 18 can be rotated to open and cover the access opening 163, and there is no need to find another place to place it when it is opened. Alternatively, the cover 18 can also be slidably connected to the housing 10, so that the cover 18 can slide to open and cover the access opening 163. Among them, when the housing 10 includes the main housing 16 and the cover 17 as described above, the access port 163 can be set on the main housing 16, and the cover 18 can be movably installed on the main housing 16. In addition, the material of the cover 18 can be made of a material that can absorb the laser emitted by the laser head 30, so that the laser emitted by the laser head 30 cannot pass through the cover 18, avoid the laser from causing harm to people, and ensure the safety during laser processing. For example: the wavelength of the laser emitted by the laser head 30 is 455nm, then the cover 18 can be made of a material that can absorb a wavelength of 455nm; or, the wavelength of the laser emitted by the laser head 30 is 1064nm, then the cover 18 can be made of a material that can absorb a wavelength of 1064nm; or, the wavelength of the laser emitted by the laser head 30 is 455nm and 1064nm, then the cover 18 can be made of a material that can absorb wavelengths of 455nm and 1064nm, or a filter is added. Alternatively, the cover 18 can also be made of a black material.

[0076] In one embodiment of the present application, the laser processing equipment 100 further includes a detection switch 70 . The detection switch 70 is disposed on the housing 10 . The detection switch 70 is used to detect whether the cover 18 is opened.

[0077] In this embodiment, the opening of the cover 18 can be detected by the detection switch 70, and the opening signal is transmitted to the laser head 30 or the main control system, so that when the cover is opened, the laser head 30 stops emitting light or reduces the light output power, thereby reducing the possibility of causing harm to the human body, which is conducive to further improving the safety of the use of the laser processing equipment 100. Among them, the detection switch 70 and the laser head 30 can be directly electrically connected, and of course, they can also be indirectly electrically connected through the control board of the laser processing equipment 100. In addition, the detection switch 70 can be a Hall sensor, when the cover 18 is rotated to open, it can detect the approach of the corresponding magnet on the cover 18 and trigger the cover 18 opening signal. Alternatively, the detection switch 70 can also be a contact sensor, when the cover 18 is rotated to open, it can detect the approach of the corresponding part on the cover 18 and trigger the cover 18 opening signal. Therefore, the present application does not limit the specific type of the detection switch, which can be used to detect the opening of the cover 18 and transmit it to the controller. In addition, when the cover 18 is disposed on the outside of the main housing 16 of the casing 10, the detection switch 70 may be disposed on the outer surface of the main housing 16, for example, the front outer surface of the main housing 16, or the upper outer surface. When the cover 18 is accommodated and installed in the access port 163 of the main housing 16 of the casing 10, the detection switch 70 may be disposed on the inner side of the access port 163. It can be seen that the present application does not limit the setting position of the detection switch 70. In addition, the number of the detection switch 70 may be one, or two or more, and may be respectively located on the left and right sides of the front surface of the casing 10 to increase the detection data and improve the accuracy of the detection.

[0078] Please refer to Figure 3 ,as well as Figures 10 to 12 In one embodiment of the present application, the laser processing equipment 100 also includes a grid structure 50, which is arranged in the exhaust port 13; the grid structure 50 includes a plurality of grid plates 51, and the plurality of grid plates 51 are arranged in sequence along a center line perpendicular to the exhaust port 13, and each two adjacent grid plates 51 enclose a gas gap 511, and the gas flow direction of the gas gap 511 and the center line of the exhaust port 13 form an acute angle.

[0079] In this embodiment, a plurality of inclined grid plates 51 in the grid structure 50 are arranged to enclose and form an inclined air gap 511. This can reduce the possibility that the laser emitted by the laser head 30 is directly emitted from the exhaust port 13, thereby further improving the anti-leakage effect of the laser, and further improving the safety of the use of the laser processing equipment 100. When the laser processing equipment 100 is in a normal placement and use state, the center line of the exhaust port 13 can be horizontal, and the air gap 511 can be arranged to be inclined upward from the inside to the outside of the housing 10, or it can be arranged to be inclined downward.

[0080] Please refer to Figures 10 to 12 In one embodiment of the present application, the grille structure 50 further includes a grille frame 53 , a plurality of grille plates 51 are connected inside the grille frame 53 , and the grille frame 53 is installed at the exhaust port 13 .

[0081] In this embodiment, by arranging a plurality of grille plates 51 in the grille frame 53, the grille structure 50 can be formed into a module, and then installed in the exhaust port 13 of the housing 10 at one time, thereby facilitating the installation and setting of the grille structure 50 on the housing 10. In order to improve the convenience of connecting the grille structure 50 and the main housing 16, the grille frame 53 can be connected by screws to simplify the assembly process while ensuring the stability of the connection between the two.

[0082] Please refer to Figures 1 to 3 ,as well as Fig.10 In one embodiment of the present application, the laser processing equipment 100 is defined as having an upper surface 10a and a lower surface 10b that are arranged back to back in the vertical direction, and a front surface 10c and a rear surface 10d that are arranged back to back in the horizontal direction, the air inlet 12 is arranged on the lower surface 10b, and the exhaust port 13 is arranged on the rear surface 10d.

Among them, the upper surface 10a is the side away from the ground, the lower surface 10b is the side facing the ground, the front surface 10c can be the side facing the personnel when operating the laser processing device 100, and the rear back surface 10d can be the side away from the personnel when operating the laser processing device 100. The air inlet 12 is set on the lower surface 10b so that it can be hidden, which is conducive to improving the aesthetics of the appearance of the housing 10, and even if laser leakage occurs at the air inlet 12, it will not cause harm to outsiders. Similarly, the exhaust port 13 is set on the rear back surface 10d, which is also inconvenient to be observed, which is also conducive to improving the aesthetics of the appearance of the housing 10. Moreover, since it is usually away from the side where the personnel are, even if laser leakage occurs at the exhaust port 13, it is still not easy to cause harm to outsiders. In addition, part of the access opening 163 described above can be set on the upper surface 10a, and the other part can be set on the front surface 10c, so that the access opening 163 covers a wider area and is convenient for placing the workpiece into the processing chamber 11, or taking it out of the processing chamber 11. In addition, control buttons (such as start, pause, etc.) can be set on the front surface 10c to facilitate personnel to control the laser processing equipment 100.

[0085] In this embodiment, the airflow driving member 40 is arranged in the processing chamber 11, so that it can be hidden, thereby facilitating the isolation and protection thereof and the compactness of the arrangement. The airflow driving member 40 is arranged corresponding to the exhaust port 13, so that it can accurately and efficiently draw the airflow in the processing chamber 11 to the exhaust port 13 for discharge, thereby facilitating the efficiency of discharging the smoke in the processing chamber 11.

[0086] In one embodiment of the present application, please refer to Fig.13 The laser processing equipment 100 also includes a purification component 80 , and the purification component 80 is connected to the exhaust port 13 .

The purification component 80 may be disposed on the outside of the housing 10, or may be disposed on the inside of the housing 10. However, when the airflow driving member 40 is also disposed on the inside of the housing 10, the airflow driving member 40 may be connected to one end of the purification component 80 away from or close to the exhaust port 13.

[0088] Of course, please refer to Fig.13 In another embodiment, the laser processing device 100 may also include a collecting component 90, which may be connected to the exhaust port 13 to collect the exhausted smoke and prevent it from being directly discharged to the outside and causing air pollution.
