Detailed implementation mode
[0024] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments.
[0025] In the description of the present invention, it should be understood that the orientation or positional relationship indicated by the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc. is based on the orientation or positional relationship shown in the accompanying drawings, and is only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be construed as a limitation to the present invention.
[0026] Embodiment:
[0027] Refer to Figures 1 - 6 , a visual laser engraving device, including a housing 1, a laser engraving head 202 is arranged in the housing 1, the laser engraving head 202 is used for laser engraving, a laser emitter 2 is installed in the housing 1, a first reflector 401 is fixedly connected in the housing 1, and the emission port 4 of the laser engraving head 202 is horizontally irradiated onto the first reflector 401; a calibration laser 5 is installed in the housing 1, and the calibration laser 5 is perpendicular to the laser emitter 2; a one-way transparent glass 501 is fixedly installed in front of the emission end of the calibration laser 5, and the one-way transparent glass 501 is located directly in front of the emission port 4; the one-way transparent glass 501 is at 45°.
[0028] The laser reflected by the laser emitter 2 and the calibration laser 5 enters the laser engraving head 202 after being reflected by the first reflector 401, and then irradiates onto the object to be processed.
[0029] The calibration laser 5 emits low-energy laser, which plays a role in calibration; the laser emitter 2 emits high-energy laser, which plays a role in engraving.
[0030] The laser engraving head 202 is located above the object to be processed.
[0031] One-way perspective glass 501 allows light to pass through on one side and reflects light on the other side. The laser emitted from the emission port 4 shines on the one-way perspective glass 501, which is the side that allows light to pass through, and then shines on the first reflector 401. The laser reflected by the calibration laser 5 shines on the one-way perspective glass 501, which is the side that does not allow light to pass through, and then the laser is reflected to the first reflector 401. When they converge on the first reflector 401, they are all at the same point, and then are reflected into the laser engraving head 202 through the first reflector 401. Therefore, when the lasers reflected by the laser emitter 2 and the calibration laser 5 shine on the surface of the object to be processed, they will all be at the same point and the positions will overlap.
[0032] Such as Figure 1 and Figure 4 , a carving plate 101 is fixedly connected inside the housing 1. The laser engraving head 202 is located above the carving plate 101. The carving plate 101 is used to place the object to be carved. The laser engraving head 202 moves above the carving plate 101 for carving.
[0033] During carving, place the object to be processed inside the housing 1, that is, on the carving plate 101. Before carving, start the calibration laser 5. The low-energy laser emitted is reflected by the first reflector 401 and then shines on the object to be processed for calibration. Since the position irradiated by the calibration laser 5 is the position of later laser carving, before carving, the staff can judge the next carving position by observing the position irradiated by the calibration laser 5, and then can judge whether the carving position is the specified carving position to ensure the carving accuracy.
[0034] After the position is correct and it is confirmed that carving is to be carried out at the specified carving position, start the laser emitter 2 and carry out carving through the laser engraving head 202.
[0035] Through the cooperation of the calibration laser 5 and the one-way perspective glass 501, before carving, emit low-energy laser to shine on the surface of the object to be carved. The staff judges whether it is the required carving position by observing the position of the laser, achieving the purpose of visualization. Calibrate through the laser position, and then confirm the accuracy of the carving position to ensure that the required carving position is consistent with the actual required carving position.
[0036] Such as Figure 1 , Figure 4 , Figure 5 , a moving frame 6 is slidably connected inside the housing 1. The moving frame 6 slides back and forth at the top, that is, approaches or moves away from the laser emitter 2. A moving cover 201 is slidably connected to the moving frame 6. The moving cover 201 slides left and right on the moving frame 6, that is, slides parallel to the laser emitter 2. The moving frame 6 is directly above the carving plate 101.
[0037] The laser engraving head 202 is fixedly installed at the bottom of the moving cover 201.
[0038] The moving frame 6 and the moving cover 201 drive the planar movement of the laser engraving head 202 in two directions, and then engraving is performed.
[0039] The moving frame 6 and the moving cover 201 are driven to move by a driving unit. The driving unit can be a cylinder. A set of cylinders is arranged in the housing 1 to push the moving frame 6 to move, and then a set of cylinders is arranged on the moving frame 6 to push the moving cover 201 to move.
[0040] The driving unit can also be a motor plus a ball screw pair. A set of motors is arranged on the housing 1 and the moving frame 6 respectively, and then the corresponding lead screws are driven to rotate. The moving frame 6 and the moving cover 201 are threadedly connected to the corresponding lead screws, and then the moving frame 6 and the moving cover 201 are driven to move respectively.
[0041] The driving unit can also be a motor plus a belt. The moving frame 6 and the moving cover 201 are fixed on two belts, and then two sets of motors drive the corresponding belts to move, and then the moving frame 6 and the moving cover 201 are driven to move respectively.
[0042] Such as Figures 3 - 5 , a second reflector 402 is fixedly installed on the moving frame 6; a through hole 7 is provided on the moving frame 6, and a light inlet 403 is provided on the side wall of the moving cover 201.
[0043] The first reflector 401 reflects the laser emitted by the laser emitter 2 and the calibration laser 5 to the second reflector 402, and then is reflected into the light inlet 403 through the second reflector 402, enters the moving cover 201 through the light inlet 403. Optical lenses are also provided in the moving cover 201, and then the laser is reflected into the laser engraving head 202 through the optical lenses in the moving cover 201 and emitted for engraving.
[0044] When the laser is reflected from the first reflector 401 to the second reflector 402, the laser passes through the through hole 7, and through the through hole 7, the laser is prevented from being blocked by the moving frame 6.
[0045] The first reflector 401, the second reflector 402, the one-way transparent glass 501, and the optical lenses are all designed at 45°.
[0046] Such as Figure 6 , a top door 801 is provided on the top of the housing 1, an observation window 802 is provided on the top door 801, and a side door 8 is provided on the side wall of the housing 1.
[0047] During the engraving process, when taking and placing the object to be engraved, and when cleaning the particulate debris during engraving, the top door 801 and the side door 8 can be flexibly opened according to the actual situation to improve convenience.
[0048] Before and during engraving, the staff can also observe the situation through the observation window 802. Before engraving, the staff judges the position irradiated by the laser emitted by the calibration laser 5 through the observation window 802, which is more intuitive and visual. Furthermore, it can be directly judged whether the engraved position is consistent with the required engraved position.
[0049] Such as Figure 1 , a lamp strip 701 is provided on the inner wall of the housing 1. The lamp strip 701 is inclined downward by 5-15°, preferably 10°, for lighting, so that the staff can better observe the situation inside the housing 1.
[0050] Heat dissipation holes 3 are provided on the side wall of the housing 1, and heat dissipation is carried out through the heat dissipation holes 3.
[0051] The above is only a preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution of the present invention and its inventive concept, makes equivalent substitutions or changes, and should be covered by the protection scope of the present invention.
