[0030] Referring to Figure 1 , Figure 2 , it is provided that a laser energy adjusting device according to an embodiment of the present application comprises a housing 1 and a laser weak light assembly 2; in some embodiments, the laser reflectivity of the laser weak light assembly 2 is 99.8% to 99.9%, and the light transmittance is 0.1% to 0.2%; the laser weak light assembly 2 reflects 99.8% to 99.9% of the incident laser light and only transmits 0.1% to 0.2% of the output laser light.
[0031] In this embodiment, the laser reflectivity of the laser weak light assembly 2 is 99.8%, and the light transmittance is 0.2%.
[0032] Referring to Figure 2As shown, in some embodiments, the outer casing 1 includes a first casing 11 and a second casing 12. The first casing 11 is mounted on the second casing 12. The first casing 11 is provided with a light inlet 111, and the second casing 12 is provided with a first light outlet 121. The light inlet 111 and the first light outlet 121 are arranged parallel to each other and on the output optical axis 100.
[0033] The laser dimming component 2 includes at least one reflector 21, which is installed inside the housing 1 and located on the output optical axis 100, and forms a set angle between the reflector 21 and the output optical axis 100.
[0034] In this embodiment, a laser dimming component 2 is disposed between the light inlet 111 and the first light outlet 121. The strong reflective properties of the laser dimming component 2 are used to reflect most of the light, leaving only a small amount of laser light to pass through, thereby achieving the effect of weakening the laser energy so as to output laser energy of appropriate power to meet the needs of the sensor or device.
[0035] In some embodiments, the set included angle is 30° to 60°. Specifically, the set included angle can be set to any one of 30°, 45°, and 60° or a range formed between any two values.
[0036] This application embodiment adjusts the tilt angle of the laser weakening component 2 by setting a set angle, thereby achieving the effect of weakening the laser energy of the input light, thus meeting the effect of providing the appropriate power of laser energy required by the sensor or device.
[0037] The laser dimming component 2 described below includes a reflector 21, which, after being coated, can reflect 99.8% of the laser light and transmit 0.2% of the laser light.
[0038] Please see Figure 2 As shown, in some embodiments, the laser dimming component 2 is installed at an angle inside the housing 1. In this embodiment, the laser dimming component 2 includes a reflector 21, which is installed at an angle inside the housing 1, and the reflector 21 forms a set angle with the output optical axis 100.
[0039] The first housing 11 is also provided with at least one second light-emitting port 112. The axis of the second light-emitting port 112 is perpendicular to the output optical axis 100. In this embodiment, the first housing 11 is provided with a second light-emitting port 112, and the reflected light from the laser dimming component 2 is output through the second light-emitting port 112. Figure 2 The reflected laser is shown.
[0040] In this embodiment, the second light outlet 112 enables the reflected light from the laser weak light component 2 to be output from the laser energy adjustment device, thereby avoiding damage to the inside of the laser energy adjustment device or affecting the laser energy of the output laser.
[0041] Please continue reading. Figure 2 As shown, in some embodiments, the housing 1 further includes a cooling element 13, which is mounted on the second light outlet 112.
[0042] In this embodiment, the cooling element 13 can dissipate heat and withstand high laser energy when receiving laser output from the second light outlet 112, thus avoiding damage to the internal components of the laser energy adjustment device or affecting the output laser energy.
[0043] Specifically, in this embodiment, the surface of the cooling element 13 facing the laser weak light component 2 is corrugated or zigzag-shaped. By setting the surface shape of the cooling element 13, the surface area of the cooling element 13 is increased, the formation of hot spots on the surface of the cooling element 13 is reduced, and the cooling element 13 can distribute heat evenly, which helps to improve the cooling efficiency of the cooling element 13.
[0044] In some embodiments, the housing 1 further includes a sealing plate 14, which is mounted on the first housing 11 and completely covers the second light outlet 112; the sealing plate 14 is provided with a fluid cooling assembly (not shown in the figure), which is in contact with the side of the cooling component 13 away from the laser weak light component 2.
[0045] In some embodiments, the fluid cooling component can be configured as a water-cooled cooling component or an air-cooled cooling component. In this embodiment, the fluid cooling component is a water-cooled cooling component. The cold head of the water-cooled cooling component contacts the side of the cooling element 13 away from the laser weak light component 2. Both the water-cooled cooling component and the sealing plate 14 are light-transmitting or transparent components to avoid affecting the output of the reflected laser.
[0046] In this embodiment, a sealing plate 14 with a fluid cooling component is provided on the second light outlet 112, which provides a certain cooling and heat dissipation effect on the cooling component 13 and improves the ability of the structure formed by the cooling component 13 and the sealing plate 14 to withstand high-energy laser irradiation.
[0047] Please continue reading. Figure 2 As shown, the first housing 11 forms a first mating slope on the side facing the second housing 12, and the second housing 12 forms a second mating slope on the side facing the first housing 11. The first mating slope and the second mating slope are in surface-to-surface contact.
[0048] In this embodiment, a sealing groove 15 is provided between the first docking inclined surface and the second docking inclined surface, and the sealing groove 15 forms a set angle with the output optical axis 100; the laser weak light component 2 is installed in the sealing groove 15. Specifically, a reflector 21 is provided in the sealing groove 15, and the reflector 21 is sealed in the sealing groove 15, and a seal is formed between the reflector 21 and the sealing groove 15 by a sealing member.
[0049] In other embodiments, when the laser dimming component 2 consists of multiple reflectors 21, the multiple reflectors 21 are stacked and arranged in the sealing groove 15.
[0050] This embodiment of the application sets the first inclined surface and the second inclined surface to be in surface contact, so that the first housing 11 and the second housing 12 can be self-aligned during installation, thereby improving the assembly efficiency of the housing 1. At the same time, the inclined surface contact can improve the pressure distribution between the first housing 11 and the second housing 12, reduce wear and improve structural stability. In addition, the sealing groove 15 is provided to facilitate the positioning and installation of the laser weak light component 2. Since the sealing groove 15 is designed with a fixed angle between it and the output optical axis 100, the tilt angle formed after the laser weak light component 2 is installed can be ensured to ensure the stability of the laser energy output.
[0051] In other embodiments, in addition to providing a sealing groove 15 between the first mating slope and the second mating slope, at least one mounting groove (not shown in the figure) can also be formed in the housing 1, and the mounting groove forms a set angle with the output optical axis 100; the reflector 21 is correspondingly installed in the mounting groove.
[0052] Specifically, multiple mounting slots are evenly arranged within the first housing 11 and / or the second housing 12, and the multiple mounting slots can be arranged in parallel or form a certain angle between them, so as to facilitate the positioning and installation of multiple reflectors 21.
[0053] In this embodiment, by further providing multiple mounting slots within the housing 1, multiple reflectors 21 can be installed within the housing 1. This allows for the stacking of reflectors 21 to weaken the laser energy when the transmittance of a single reflector 21 is insufficient, thereby achieving the desired laser energy power for the sensor or device. Simultaneously, since the mounting slots are designed with a fixed angle between them and the output optical axis 100, the tilt angle formed after the reflectors 21 are installed can be ensured to guarantee the stability of the laser energy output.
[0054] In some embodiments, the laser energy adjustment device further includes a beam adjustment component (not shown in the figure), which is mounted on the housing 1 and located at the first light outlet 121.
[0055] This application embodiment achieves the focusing and dispersion of the emitted laser beam by setting a beam adjustment component at the first light outlet 121, so that the output laser beam can meet the processing requirements of subsequent sensors or equipment.
[0056] Based on the laser energy adjustment device described above, this application embodiment also provides a laser processing device.
[0057] In some embodiments, the laser processing equipment includes a laser emitting device and a laser energy adjustment device as described above. The laser energy adjustment device is installed at the output end of the laser emitting device. The emitted laser from the laser emitting device enters from the light inlet 111 of the laser energy adjustment device and is output from the first light outlet 121 of the laser energy adjustment device after being weakened by the laser energy.
[0058] The laser processing equipment provided in this application embodiment sets up the laser energy adjustment device as described above at the output end of the laser emission device. The strong reflection characteristics of the laser weak light component 2 inside the laser energy adjustment device are used to reflect most of the light, leaving only a small amount of laser light to pass through, thereby achieving the effect of laser energy weakening, so as to output laser energy with appropriate power to meet the needs of the sensor or equipment.

The accompanying drawings show preferred embodiments of this application, but do not limit the patent scope of this application.
