Description

Technical Field

[0001] This disclosure relates to the field of solid-state ultraviolet laser technology, specifically to a light-emitting component used in solid-state ultraviolet lasers. Background Technology

[0002] Solid-state ultraviolet (SUV) lasers are lasers that generate ultraviolet beams. Because the ultraviolet wavelength is only about one-third that of the infrared wavelength, they enable higher precision processing. Furthermore, the photon energy of ultraviolet lasers is approximately three times that of infrared lasers. SUV lasers have significantly expanded and improved the application range and efficiency of laser cold processing. In practical production applications, 355nm SUV lasers are commonly used in the market due to their extremely high repetition rate, making them highly effective in cutting ultra-thin materials, such as FPC flexible circuit boards, OLED screens, and ultra-thin metals and non-metals.

[0003] Solid-state ultraviolet (SUV) lasers have extremely high requirements for the cleanliness of the cavity environment. Not only must the volatilization of organic gases from all components within the cavity be kept extremely low, but strong humidity control is also essential. Therefore, the design of SUV lasers must ensure a strictly sealed cavity. Furthermore, as an industrial product, UV lasers must guarantee stable light output. The addition of a window ensures both effective cavity sealing and stable light output. Currently, various materials can be used for the window, such as fused silica, calcium fluoride, and sapphire. However, these materials have a certain damage threshold and are easily damaged by ultraviolet light. Additionally, the outer layer of a SUV laser is prone to dust accumulation, further increasing the window's damage rate.

[0004] Currently, in the production and design of ultraviolet lasers, the window plate is typically placed at a Brewster angle to the emitted ultraviolet laser. This provides significant protection for the window plate, but it still requires periodic replacement, and each instance of damage is a small, point-like injury. This is highly detrimental to the long-term use of the laser and industrial production. While existing technologies offer replaceable window plate structures—allowing replacement of damaged points by removing screws—this process inevitably involves temporary air leakage and is relatively complex, resulting in poor performance in practical applications and urgently requiring improvement. Summary of the Invention

[0005] In view of the above-mentioned defects or deficiencies in the prior art, this application aims to provide a light output component for solid-state ultraviolet lasers that enables convenient point switching compared to the prior art.

[0006] In a first aspect, this application provides a light-emitting component for a solid-state ultraviolet laser, wherein a first light-emitting port is provided on the sidewall of the solid-state ultraviolet laser, comprising:

[0007] A first base is sealed and fixed to the outside of the first light outlet; a first passage is provided inside the first base, and the axis of the first passage coincides with the axis of the first light outlet.

[0008] An adjustment seat has a second passage at its center that is connected to the first passage, and a first window plate is fixedly connected in the second passage. The adjustment seat is rotatably disposed on the first base on a side relatively away from the first light outlet. The adjustment seat is dynamically sealed to the first base. The axis of the first window plate and the axis of the first light outlet form a Brewster angle.

[0009] An adjustment cover plate is detachably fixed to the first base to press the adjustment seat, and the adjustment cover plate is provided with a second light outlet.

[0010] The ultraviolet light emitted from the first light outlet enters the first path, passes through the first window, and exits from the second light outlet. Therefore, by rotating the adjustment base, the penetration position of the ultraviolet light on the first window can be changed, enabling portable point replacement.

[0011] According to the technical solution provided in the embodiments of this application: a first mounting groove is provided on the side of the first base that is relatively far away from the first light outlet, and the first mounting groove is connected to the first passage; the adjustment seat is rotatably disposed in the first mounting groove.

[0013] According to the technical solution provided in the embodiments of this application: the adjustment seat has an annular protrusion on the side relatively close to the third mounting groove, which surrounds the annular extension.

Therefore, without disassembling any components, the point can be changed more conveniently by rotating the part of the adjustment seat exposed outside the first base. The operation is convenient. During the point change process, the pressing cover plate always presses the adjustment seat, which can avoid air leakage to the greatest extent and keep the ultraviolet laser cavity in a sealed state.

In the second state, the first telescopic end is engaged with the locking groove. When the adjusting seat is rotated, the first telescopic end can switch between the first state and the second state.

[0018] A straight line passing through the center of the second ring rail and the center of the first telescopic end is designated as the first center line, and the two second telescopic ends are located on both sides of the first center line; a straight line passing through the center of the second ring rail and perpendicular to the first center line is designated as the second center line, and the two second telescopic ends are located on one side of the second center line, while the first telescopic end is located on the other side of the second center line.

[0019] The two second telescopic ends and the one first telescopic end form a triangle, pressing the adjusting seat together, which ensures that the adjusting seat remains stable during rotation even under uneven force.

[0020] According to the technical solution provided in the embodiments of this application: on the side of the first base where the opening is provided, a first stop is provided along the edge of the opening; a second stop is provided on the adjustment cover plate at a position corresponding to the opening; a space is formed between the first stop and the second stop to protect the portion of the adjustment seat exposed at the opening, thereby preventing accidental contact and damage to the adjustment seat.

[0021] According to the technical solution provided in the embodiments of this application: a second mounting groove communicating with a first passage is provided on the side of the first base relatively close to the first light outlet, and the axis of the second mounting groove coincides with the axis of the first light outlet; a second base that seals with the first base is provided in the second mounting groove, the second base including: a mounting seat that mates with the second mounting groove, and an extension seat extending along the first passage is provided on the side of the mounting seat relatively away from the first light outlet; a third passage penetrating the mounting seat and the extension seat is provided in the second base; a second inclined surface is provided on the end of the extension seat relatively away from the first light outlet; a second window piece is fixedly connected to the second inclined surface; the axis of the second window piece forms a Brewster angle with the axis of the first light outlet;

[0022] The ultraviolet light emitted from the first output port enters the third path, passes through the second window, and then through the first window before exiting from the second output port. The second window further ensures the sealing of the solid-state ultraviolet laser cavity.

[0023] According to the technical solution provided in the embodiments of this application: the second passage is provided with a bearing ring fixedly connected to its inner wall, and the first window piece is fixedly connected to the bearing ring.

[0024] According to the technical solution provided in the embodiments of this application: the side wall of the adjustment seat is provided with adjustment marks corresponding to the locking groove, and an adjustment groove is provided between two adjacent adjustment marks. The adjustment groove can be used to lock external adjustment tools.

[0025] According to the technical solution provided in the embodiments of this application: the second light outlet includes: a circular fourth passage located at the center of the adjustment cover plate and a U-shaped passage disposed on one side of the fourth passage and connected thereto; the ultraviolet light emitted from the first light outlet enters the first passage, passes through the first window, and is emitted from the U-shaped passage.

[0026] According to the technical solution provided in the embodiments of this application, the device further includes a hollow cover that mates with the first base. The cover has a first end that mates with the top of the first base and a second end that mates with the bottom of the first base. A third inclined surface is formed on the side of the cover relatively close to the first base. A third light-emitting port for ultraviolet light to be emitted is provided on the side of the cover relatively far from the first base.

By rotating the adjustment base, the penetration position of the ultraviolet light on the first window can be changed, enabling portable point replacement. The first base is sealed to the solid-state ultraviolet laser, the adjustment base and the first base are dynamically sealed, and the adjustment cover is fixed to the first base and presses against the adjustment base, ensuring the airtightness of the solid-state ultraviolet laser cavity.

[0037] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. This application will now be described in detail with reference to the accompanying drawings and embodiments.

[0038] like Figure 1 and Figure 2 As shown, this embodiment provides a light-emitting component for a solid-state ultraviolet laser. The solid-state ultraviolet laser has a first light-emitting port 51 on its sidewall 50, including:

[0039] A first base 10 is sealed and fixed to the outside of the first light outlet 51; a first passage 11 is provided inside the first base 10, and the axis of the first passage 11 coincides with the axis of the first light outlet 51.

[0040] Specifically, such as Figure 2As shown, the first base 10, from top to bottom, includes a first plane parallel to the sidewall of the solid-state ultraviolet laser, a first inclined surface 12, and a second plane parallel to the first plane. The first base 10 is fixed to the sidewall 50 of the solid-state ultraviolet laser and the outside of the first light-emitting port 51 through threaded through holes on the first and second planes. The normal of the first inclined surface 12 forms a Brewster angle with the axis of the first light-emitting port 51. A third sealing groove 17 is provided on the side of the first base 10 relatively close to the first light-emitting port 51, surrounding the second mounting groove 15, and a third sealing ring 18 is fitted inside the third sealing groove 17.

[0041] like Figure 1 and Figure 2 As shown, the adjustment seat 200 has a second passage 210 at its center that is connected to the first passage 11, and a first window piece 230 is fixedly connected in the second passage 210. The adjustment seat 200 is rotatably disposed on the first base 10 on a side relatively away from the first light outlet 51. The adjustment seat 200 is dynamically sealed to the first base 10. The axis of the first window piece 230 and the axis of the first light outlet 51 form a Brewster angle.

[0042] The adjustment cover plate 30 is detachably fixed to the first base 10, and the adjustment cover plate 30 is provided with a second light outlet 31;

[0043] Specifically, such as Figure 4 As shown, four threaded through holes are provided on the four corners of the adjustment cover plate 30 on the outer side of the second light outlet 31, and threaded holes are provided at the corresponding positions on the side of the first base 10 that is relatively far away from the first light outlet. The adjustment cover plate 30 and the first inclined surface 12 are fixed together by screws.

[0044] Accordingly, the ultraviolet light emitted from the first light outlet 51 enters the first path 11, passes through the first window 230, and will be emitted from the second light outlet 31.

[0045] Furthermore, such as Figure 1 and Figure 2 As shown, the first base 10 has a first mounting groove 13 on the side opposite to the first light outlet 51, and the first mounting groove 13 is connected to the first passage 11; the adjustment seat 200 is rotatably disposed in the first mounting groove 13.

[0046] Specifically, such as Figure 2 As shown, the first mounting groove 13 includes a bottom surface that is parallel to the side of the first base 10 that is relatively far from the first light outlet 51 and located relatively close to the first light outlet, and a side surface that is perpendicular to the bottom surface of the first mounting groove 13.

[0047] Furthermore, such as Figure 2 As shown, a third mounting groove 16, which is connected to the first mounting groove 13, extends from the center of the bottom of the first mounting groove to the side away from the first mounting groove; an annular extension 240, which is engaged with the third mounting groove 16, is provided on the side of the adjustment seat 200 that is relatively close to the first passage 11, and the annular extension 240 and the third mounting groove 16 are dynamically sealed.

[0048] Specifically, such as Figure 2 As shown, the side surface of the third mounting groove 16 is perpendicular to the bottom surface of the first mounting groove 13, and the bottom surface of the third mounting groove 16 is parallel to the bottom surface of the first mounting groove 13 and located on a side relatively far from the first mounting groove 13. The diameter of the third mounting groove 16 is smaller than the diameter of the first mounting groove 13. The outer diameter of the annular extension 240 is equal to the inner diameter of the third mounting groove 16. The annular extension 240 has an annular first sealing groove 241 in the middle, and a first sealing ring 242 is fitted inside the first sealing groove 241. A dynamic seal is formed between the annular extension 240 and the third mounting groove 16. The annular extension increases the sealing performance and stability of the adjusting seat during rotation.

[0049] Furthermore, such as Figure 2 As shown, the adjustment seat 200 has an annular protrusion 201 surrounding the annular extension 240 on the side relatively close to the third mounting groove 16.

[0050] Specifically, such as Figure 2 As shown, the outer diameter of the annular protrusion 201 is smaller than the outer diameter of the adjusting seat 200, and the inner diameter of the annular protrusion 201 is smaller than the outer diameter of the annular extension 240.

[0051] Furthermore, such as Figure 1 As shown, the first mounting groove 13 has at least one opening 14 exposed outside the first base 10 on its side wall, and the adjustment seat 200 is exposed outside the opening 14 at a position corresponding to the opening 14.

[0052] Specifically, such as Figure 1 As shown, the opening 14 includes a bottom edge located on the first base 10, relatively close to the first light outlet 51 and parallel to the adjustment base 200, and two side edges perpendicular to its bottom edge. The height of the two side edges of the opening 14 is equal to the thickness of the adjustment base 200.

[0053] Furthermore, such as Figure 1 and Figure 3As shown, the adjusting seat 200 has a first ring rail 202 surrounding the second passage 210 on the side relatively away from the first passage 11; the adjusting cover plate 30 has a first snap-fit ​​groove 32 and a positioning member 33 is fitted in the first snap-fit ​​groove 32; the positioning member has a first telescopic end 34 on the side relatively close to the adjusting seat, which can be fitted with the first ring rail 202; when the adjusting seat 200 is rotated, the first telescopic end 34 can only move within the first ring rail 202, which can further limit the position of the adjusting seat 200 relative to the first base 10 to be fixed.

[0054] The first ring rail 202 has a plurality of locking grooves 203 arranged in a ring array, and the locking grooves 203 are connected to the first ring rail 202; the first telescopic end 34 has two states. In the first state, the first telescopic end 34 is engaged with the first ring rail 202; in the second state, the first telescopic end 34 is engaged with the locking grooves 203; when the adjusting seat 200 is rotated, the first telescopic end 34 can switch between the first state and the second state.

[0055] Specifically, when the adjustment seat 200 is rotated until the first telescopic end 34 enters the locking groove 203, the ultraviolet light penetrates the first window piece 230 at exactly the switching point position of the first window piece 230.

[0056] Furthermore, such as Figure 3 As shown, the adjustment seat 200 has a second ring rail 204 arranged around the second passage 210 on the side relatively away from the first passage 11. The second ring rail 204 is located between the first ring rail 202 and the second passage 210.

[0057] like Figure 1 As shown, the adjusting cover plate 30 is provided with two second snap-fit ​​grooves 35, and a balancing component 36 is fitted in the second snap-fit ​​grooves 35; the balancing component 36 is provided with a second telescopic end 37 on the side relatively close to the adjusting seat 200, which can be fitted with the second ring rail 204; when the adjusting seat 200 is rotated, the relative position between the second telescopic end 37 and the second ring rail 204 can be adjusted.

[0058] Specifically, the first telescopic end 34 is an elastic compression ball end fixed to one end of the positioning post 33 by a spring. The end of the positioning post 33 near the first telescopic end 34 is a hollow structure, with the spring located inside the hollow structure. The ball end can partially enter the hollow structure of the positioning post 33 through the compression adjustment seat 200. The second telescopic end 37 is an elastic compression ball end fixed to one end of the balance post 36 by a spring. The end of the balance post 36 near the second telescopic end 37 is a hollow structure, with the spring located inside the hollow structure. The ball end can partially enter the hollow structure of the balance post 36 through the compression adjustment seat 200.

[0059] Preferably, the positioning post 33 and the balance post 36 are ball-head plungers, and the first locking groove 32 and the second locking groove 35 have trapezoidal locking grooves inside. The end of the positioning post 33 that is relatively close to the first telescopic end 34 and the end of the balance post 36 that is relatively close to the second telescopic end 37 are trapezoidal structures that match the trapezoidal locking groove inside the second locking groove 35. By pressing the adjusting seat 200, the positioning post 33 and the balance post 36 can be tightly locked onto the adjusting cover plate 30.

[0060] Preferably, the positioning pin 33 and the balance pin 36 are ball screws, the first locking groove 32 and the second locking groove 35 are threaded holes, and the positioning pin 33 and the balance pin 36 are threadedly fixed to the adjusting cover plate 30.

[0061] To determine the positions of the first telescopic end 34 and the second telescopic end 37, a straight line passing through the center of the second ring rail 204 and the center of the first telescopic end 34 is designated as the first centerline, with the two second telescopic ends 37 located on either side of the first centerline. A straight line passing through the center of the second ring rail 204 and perpendicular to the first centerline is designated as the second centerline, with the two second telescopic ends 37 located on one side of the second centerline and the first telescopic end 34 located on the other side. The first telescopic end 34 and the two second telescopic ends 37 form a triangular structure, pressing against the adjusting seat 200 to ensure that the adjusting seat 200 remains under stable force.

[0062] Furthermore, such as Figure 5 As shown, on the side of the first base 10 where the opening 14 is provided, a first stop 19 is provided along the edge of the opening 14;

[0063] A second stop 38 is provided on the adjustment cover plate 30 at a position corresponding to the opening 14;

[0064] A space is formed between the first stop 19 and the second stop 38 that can protect the portion of the adjustment seat 200 exposed at the opening 14.

[0067] like Figure 1 and Figure 2 As shown, a second base 40 is provided in the second mounting groove 15 to seal with the first base 10. The second base 40 includes a mounting seat 41 that mates with the second mounting groove 15, and an extension seat 42 extending along the first passage 11 is provided on the side of the mounting seat 41 that is relatively far away from the first light outlet 51. A third passage 47 is provided in the second base 40 that penetrates the mounting seat 41 and the extension seat 42.

[0069] The ultraviolet light emitted from the first light outlet 51 enters the third path 47, passes through the second window 44, and then passes through the first window 230, before being emitted from the second light outlet 31.

[0070] Specifically, the diameter of the second mounting groove 15 is larger than the diameter of the first passage 11; a second sealing groove 45 surrounding the extension seat 42 is provided on the side wall of the mounting base 41 relatively close to the first passage 11, and a second sealing ring 46 is fitted inside the second sealing groove 45.

[0074] Furthermore, such as Figure 4 As shown, the second light outlet 31 includes: a circular fourth passage 311 located at the center of the adjustment cover plate 30 and a U-shaped passage 312 disposed on one side of the fourth passage 311 and connected thereto; the ultraviolet light emitted by the first light outlet 51 enters the first passage 11, passes through the first window 230, and will be emitted from the U-shaped passage 312.

[0075] Furthermore, such as Figure 1 and Figure 2 As shown, it also includes a hollow cover 60 that mates with the first base 10. The cover 60 has a first end 61 that mates with the top of the first base 10 and a second end 62 that mates with the bottom of the first base 10. The side of the cover 60 that is relatively close to the first base 10 is a third inclined surface 63.

[0078] Preferably, the housing 60 has a beam expander assembly mounting hole on the side relatively away from the first base 10 for connecting an external beam expander assembly.
