In an embodiment, the baffle 14 is provided with a wire passing hole 141 for the wire harness to pass through.

[0042] In the embodiment, the wire passing hole 141 is arranged at the top of the baffle 14 and penetrates to the top edge of the baffle 14, i.e., the top edge of the baffle 14 is provided with a notch to form the wire passing hole 141. In this way, when the fan assembly 2 or the control assembly needs to be overhauled, the disassembly and reconnection of the wire harness can be made easier.

[0043] In the embodiment, the wire passing hole 141 is arranged at the top of the baffle 14 and penetrates to the top edge of the baffle 14, i.e., the top edge of the baffle 14 is provided with a notch to form the wire passing hole 141. In this way, when the fan assembly 2 or the control assembly needs to be overhauled, the disassembly and reconnection of the wire harness can be made easier.

[0044] In some embodiments of the utility model, the first control element 3 is attached to one side of the partition plate 11 facing the first chamber 131, and the second control element 4 is attached to the bottom wall of the third chamber 133. The "attachment" can be close to the attachment, or it can be fixed by sticking.

[0045] For example, the first control element 3 is a main control board, and the second control element 4 is a power module. The first control element 3 is vertically arranged in the first chamber 131 and fixedly connected with the partition plate 11, so that the first control element 3 can avoid occupying a large space when being placed horizontally. Figure 4 And Figure 5 The side of the partition plate 11 facing the first chamber 131 is provided with a plurality of first mounting columns 112, and the first control element 3 is fixedly connected with the first mounting columns 112 through fasteners. The second control element 4 is arranged in the third chamber 133 and fixedly connected with the bottom wall of the third chamber 133, so that the stability of the second control element 4 during equipment operation can be ensured. Similarly, the bottom wall of the third chamber 133 is provided with a plurality of second mounting columns 113, and the second control element 4 is fixedly connected with the second mounting columns 113 through fasteners. The fasteners can be screws, so that the first control element 3 and the second control element 4 can be conveniently disassembled and reassembled when maintenance is required.

[0046] Referring to Figure 1 And Figure 3 In some embodiments of the utility model, the shell 1 further includes a top plate 15 which is detachably arranged on the top of the rear chamber 13. The top plate 15 is used to close the rear chamber 13, so as to protect the fan assembly 2 and the control assembly in the rear chamber 13, and the top plate 15 is detachably connected with the shell body 10, so that the fan assembly 2 and the control assembly can be conveniently assembled and maintained.

[0047] The top of the front chamber 12 is formed with a taking and placing opening, and the shell 1 further includes a cover plate 16 which is used to open or close the taking and placing opening. The cover plate 16 can be connected with the shell body 10 or the top plate 15. For example, the cover plate 16 can be rotatably connected with the shell body 10 or the top plate 15, so as to open and close the taking and placing opening by rotating the cover plate 16. Alternatively, the cover plate 16 can be slidably connected with the shell body 10, so as to open and close the taking and placing opening by sliding the cover plate 16. Of course, the cover plate 16 and the shell body 10 can not be connected, i.e., they are separately arranged. When the taking and placing opening needs to be closed, the cover plate 16 is directly placed on the shell body 10. When the taking and placing opening needs to be opened, the cover plate 16 is directly taken away. Therefore, the connection between the cover plate 16 and the shell body 10 is not limited, and the taking and placing opening can be opened and closed, so that the operator can conveniently put the workpiece into the front chamber 12 or take out the workpiece processed from the front chamber 12. During the laser processing, the cover plate 16 is in the closed state, so that the problems such as laser overflow, outward diffusion of smoke and dust generated during laser processing, and entry of foreign matters into the front chamber 12 can be avoided.

[0048] Some embodiments of the laser processing equipment 100 further comprise an illuminating lamp 6 arranged in the front chamber 12 for illuminating the workpiece. Specifically, the illuminating lamp 6 can be arranged on the left side and / or the right side of the front chamber 12. In this way, when the illuminating lamp 6 is working, the user usually stands on the front side of the front chamber 12, and the illuminating lamp 6 arranged on the left side and / or the right side of the front chamber 12 can prevent the light emitted by the illuminating lamp 6 from directly shining into the user's eyes, thereby improving the safety of use.

[0049] Further, in some embodiments of the present application, one of the cover plate 16 and the shell body 10 is provided with a magnetic member 7, and the other is provided with a Hall sensor 8 matched with the magnetic member 7. The Hall sensor 8 is used to detect the opening and closing of the cover plate 16. The Hall sensor 8 and the illuminating lamp 6 are both electrically connected to a control element in the laser processing equipment 100. The control element controls the brightness of the illuminating lamp 6 according to the sensing signal of the Hall sensor 8.

[0050] It can be understood that the Hall sensor 8 cooperates with the magnetic member 7 to generate a sensing signal when the cover plate 16 is opened or closed. When the Hall sensor 8 senses the magnetic member 7, it indicates that the cover plate 16 is closed on the taking and placing opening. At this time, the Hall sensor 8 sends a first sensing signal to the control element (the first control element 3 or the second control element 4) electrically connected thereto, and the control element receives the first sensing signal and controls the brightness of the illuminating lamp 6 according to the first sensing signal. At this time, because the cover plate 16 is closed on the taking and placing opening, the brightness of the illuminating lamp 6 can be controlled to become brighter. When the Hall sensor 8 does not sense the magnetic member 7, it indicates that the cover plate 16 is in an open state. At this time, the Hall sensor 8 sends a second sensing signal to the control element electrically connected thereto, and the control element receives the second sensing signal and controls the brightness of the illuminating lamp 6 according to the second sensing signal. At this time, because the cover plate 16 is in an open state, the brightness of the illuminating lamp 6 can be controlled to become dimmer or the illuminating lamp 6 can be directly controlled to be turned off.

[0051] In summary, in the present embodiment, one of the cover plate 16 and the shell body 10 is provided with a magnetic member 7 such as a magnet, and the other is provided with a Hall sensor 8. The Hall sensor 8 and the illuminating lamp 6 are both electrically connected to a control element in the laser processing equipment 100. In this way, the brightness of the illuminating lamp 6 is associated with the opening and closing of the cover plate 16, so that the illuminating lamp 6 can quickly adjust its brightness according to the opening and closing of the cover plate 16, thereby improving the intelligence and flexibility of the laser processing equipment 100.

[0052] The above description is only an exemplary embodiment of the present application, and does not limit the patent scope of the present application.
