[0003] The existing high-performance 976nm wide strip semiconductor laser generates a large amount of heat when running. The prior art cools the heat sink fin area by flowing cooling liquid from a fixed inlet, first contacts the upper fin for cooling, and then flows downward for heat dissipation cooling. However, when the cooling liquid flows, the temperature is increased due to the absorption of the upper heat, and the heat exchange efficiency is significantly attenuated when flowing through the lower fin, forming a temperature gradient from top to bottom of the fin, which easily reduces the cooling efficiency of the lower heat sink fin and affects the overall cooling effect, which is inconvenient to use.

[0015] Compared with the prior art, the present application has the following beneficial effects: Firstly, this device uses a first water pump and an output pipe to spray coolant from multiple nozzles. When the coolant flows in the output pipe, it drives the turbine to rotate. The turbine rotation causes the nozzles to move intermittently back and forth, and at the same time, the turbine rotation causes the nozzles to move in a circular motion. Since the nozzles are symmetrically staggered vertically, the circular motion of the nozzles will bring the coolant into contact with the heat dissipation fins at different heights. This, combined with the gaps in the spray during rotation and the rapid sliding of the coolant, allows new coolant to continuously come into contact with the heat dissipation fins, thereby uniformly cooling the heat dissipation fins. At the same time, the U-shaped guide plate can guide the coolant above, preventing the coolant above from contacting the heat dissipation fins below and affecting cooling.

[0017] Thirdly, the device, with its slider and sealing plate, facilitates the sealing of the fixing holes during the disassembly and maintenance of the laser body, thereby preventing debris from entering the processing box and affecting subsequent use. The sliding plate, spring, trapezoidal block, and L-shaped fixing block facilitate the movement of the sealing plate to avoid obstruction during the installation of the laser body. At the same time, the laser body can be fixed after installation without step-by-step operation, reducing the labor intensity of the staff. Attached Figure Description

Detailed Implementation

[0020] To further understand the features, technical means, and specific objectives and functions achieved by the present invention, the present invention will be described in further detail below with reference to the accompanying drawings and specific embodiments.

[0021] Figures 1-12 This is the preferred embodiment of the present invention, which is described below in conjunction with the accompanying drawings. Figure 1 ~Attached Figure 12 The present invention will be further described below.

[0022] A high-performance 976nm wide-strip semiconductor laser includes an L-shaped base 1, a laser body 3 is disposed above the L-shaped base 1, a substrate 9 is fixedly disposed on the side of the laser body 3, a plurality of heat dissipation fins 10 are mounted on the side of the substrate 9, and a heat dissipation fixing mechanism adapted to the plurality of heat dissipation fins 10 is disposed on the L-shaped base 1. The heat dissipation and fixing mechanism includes a processing box 4 installed on the top of the L-shaped base 1. The side of the processing box 4 is provided with multiple fixing holes 44. The L-shaped base 1 is provided with a sealing and fixing component that is compatible with the laser body 3 and the fixing holes 44. Multiple movable tubes 14 are movably arranged inside the processing box 4. Multiple nozzles are symmetrically staggered up and down along the axis of the multiple movable tubes 14. Multiple U-shaped guide plates 43 are installed on the inner side wall of the processing box 4. The L-shaped base 1 and the processing box 4 are jointly provided with an infusion drive component that makes the movable tubes 14 move back and forth while rotating continuously.

[0023] With the above structure, during use, the heat generated by the laser body 3 is conducted out by the substrate 9 and diffused onto the heat sink fins 10. At this time, the coolant can be sprayed from multiple nozzles through the movable tube 14 by the liquid delivery drive assembly. Simultaneously, as the coolant flows, the movable tube 14 is intermittently reciprocated and rotated by the liquid delivery drive assembly. The intermittent reciprocating movement of the movable tube 14 causes the coolant to contact the heat sink fins 10 at different lateral positions. The rotation of the movable tube 14 causes the nozzles to move in a circular motion. Since the nozzles are symmetrically staggered vertically, the circular motion of the nozzles... The motion will cause the coolant to come into contact with the heat dissipation fins 10 at different heights, thus allowing the coolant to come into contact with the heat dissipation fins 10 at different positions and heights. At this time, in conjunction with the gaps in the spray of the nozzle's circumferential motion, new coolant can continuously come into contact with the heat dissipation fins 10, thereby uniformly cooling the heat dissipation fins 10. Meanwhile, the coolant at the top, after dissipating heat from the heat dissipation fins 10, will be guided by the U-shaped guide plate 43, thereby preventing the coolant at the top from coming into contact with the heat dissipation fins 10 at the bottom, thus preventing the used coolant from coming into contact with the heat dissipation fins 10 and affecting cooling.

[0024] like Figure 1 , Figure 4 , Figure 5 , Figure 7 , Figure 8 , Figure 9 and Figure 10As shown, the infusion drive assembly includes a water tank 7 mounted on the top of an L-shaped base 1. A first water pump 8 is fixed to the side of the water tank 7. An output pipe 6 is installed at the output end of the first water pump 8, and a hose 5 is installed at the other end of the output pipe 6. An L-shaped threaded block 12 is provided inside the treatment tank 4. A diversion chamber is opened on the L-shaped threaded block 12. A water inlet and multiple water distribution holes are fixed at the top and bottom of the L-shaped threaded block 12, respectively. The other end of the hose 5 is installed on the top of the water inlet. Multiple L-shaped moving blocks 13 are installed at the bottom of the L-shaped threaded block 12. A rotating hole is opened at the bottom of each of the multiple L-shaped moving blocks 13. Multiple movable pipes 14 are rotatably installed on the multiple rotating holes. Rotary joints 15 are installed at the top of the multiple movable pipes 14 and the multiple water distribution holes, respectively. A drive chamber 16 is opened on the treatment tank 4. A drive rod 17 is rotatably installed on the inner side wall of the drive chamber 16. One end of the drive rod 17 extends into the output pipe 6 and is equipped with a turbine 18. Multiple... A drive bevel gear 24 is driven by a drive chamber 16. Multiple movable rods 21 are rotatably mounted on the inner side wall of the drive chamber 16. A transmission bevel gear 23 is mounted on one end of each movable rod 21. The transmission bevel gears 23 mesh with the drive bevel gears 24. One end of each movable rod 21 extends into the processing box 4 and is mounted with a square rod 22. Each L-shaped moving block 13 has a driven chamber. A worm gear 25 is rotatably mounted on the inner wall of each driven chamber. Each movable tube 14 is fitted with a worm wheel 26. The worm wheels 26 located in the same driven chamber mesh with the worm gear 25. Round holes and square holes are respectively opened on the sides of the L-shaped moving blocks 13 and the sides of the worm gear 25. The square rods 22 pass through the two round holes and the square holes on one side in sequence. A driven unit is provided on the processing box 4 to make the L-shaped threaded block 12 move intermittently. The driven unit is installed in conjunction with the drive rod 17. A flow guiding processing unit is provided on both the L-shaped base 1 and the processing box 4.

[0025] In this design, the coolant in the water tank 7 can be output to multiple movable pipes 14 through the arrangement of the water tank 7, the first water pump 8, the output pipe 6, the hose 5, the water inlet, the flow chamber, the water distribution hole and the rotary joint 15. Through the arrangement of the drive rod 17, the turbine 18, the movable rod 21, the square rod 22, the transmission bevel gear 23, the drive bevel gear 24, the worm 25, the worm wheel 26 and the square hole, the coolant drives the movable pipes 14 to rotate while flowing.

[0026] Specifically, by outputting the coolant from the water tank 7 into multiple movable pipes 14, a diversion effect can be achieved, thereby dissipating heat from multiple heat dissipation fins 10. By causing the movable pipes 14 to rotate while the coolant is flowing, the nozzles can be driven to rotate in a circular motion while cooling. Furthermore, with the nozzles staggered vertically, the coolant can contact the heat dissipation fins 10 at different heights. At the same time, through the arrangement of the square rod 22 and the square hole, when the L-shaped moving block 13 drives the worm gear 25 to move, the worm gear 25 is similar to sliding on the square rod 22. At this time, the rotation of the square rod 22 will still drive the worm gear 25 to rotate through the square hole.

[0027] like Figure 4 , Figure 8 and Figure 9 As shown, the driven unit includes an L-shaped movable groove 45 opened on the inner wall of the processing box 4. A reciprocating screw 11 is rotatably installed on the inner side of the L-shaped movable groove 45. An L-shaped threaded block 12 is threaded onto the reciprocating screw 11. One end of the reciprocating screw 11 extends into the drive cavity 16 and is equipped with a driven bevel gear 20. An incomplete bevel gear 19 is sleeved on the drive rod 17 and meshes with the driven bevel gear 20.

[0028] In this design, the reciprocating screw 11, the incomplete bevel gear 19, and the driven bevel gear 20 facilitate the intermittent reciprocating movement of the L-shaped threaded block 12.

[0029] Specifically, by intermittently reciprocating the L-shaped threaded block 12, the nozzle can be intermittently reciprocated, thereby allowing the coolant to contact different lateral positions of the heat dissipation fins 10. At the same time, the intermittent movement avoids blank areas caused by continuous movement due to nozzle rotation, thus avoiding any impact on the cooling effect.

[0030] like Figure 9 As shown, the diameter of the incomplete bevel gear 19 is larger than the diameter of the driven bevel gear 20.

[0031] In this design, by setting the diameter ratio, it is easier to make the driven gear 20 rotate more times.

[0032] Specifically, by having the driven gear 20 rotate more times, the reciprocating screw 11 can rotate more times. At the same time, in conjunction with the intermittent transmission effect of the incomplete bevel gear 19, the movement distance of the L-shaped threaded block 12 can be guaranteed while the intermittent movement time of the L-shaped threaded block 12 is lengthened, avoiding the movement interval being too short and affecting the cooling effect under the coordination of the nozzle's circumferential motion.

[0033] like Figure 2 , Figure 4 and Figure 8As shown, the flow guiding and processing unit includes an L-shaped drain chamber 42 disposed on the processing tank 4. The inner side wall of the processing tank 4 has multiple drain holes 41 connected to the L-shaped drain chamber 42. A water outlet pipe 28 with a solenoid valve is fixedly disposed on the side of the processing tank 4. A cooling tank 27 is installed on the top of the L-shaped base 1. A through hole is fixed on the top of the cooling tank 27. The other end of the water outlet pipe 28 is installed on the through hole. A second water pump 33 is fixedly disposed on the side of the cooling tank 27. A water inlet is opened on the side of the water tank 7. A connecting pipe is installed on the output end of the second water pump 33 and the water inlet. A stirring rod 29 is rotatably mounted on the inner side wall of the cooling tank 27. Multiple stirring blades are fixed on the stirring rod 29. The stirring rod is installed in cooperation with the drive rod 17 through a transmission element. Specifically, in use, an external cooling device can be installed on the top of the cooling tank 27 to assist in cooling the coolant inside the cooling tank 27.

[0034] In this design, the cooling tank 27, water outlet pipe 28, second water pump 33, connecting pipe, drain hole 41 and L-shaped drain cavity 42 facilitate the collection of used coolant, which is then cooled by an external cooling device and transferred back into the water tank 7 for recycling. The stirring rod 29 and stirring blades are used to mix and stir the coolant in the cooling tank 27.

[0035] Specifically, by collecting the coolant, it is easier to cool it through an external cooling device. By mixing and stirring the coolant in the cooling tank 27, a certain pretreatment effect is achieved, thereby effectively improving the subsequent cooling efficiency.

[0036] like Figure 2 , Figure 3 and Figure 8 As shown, the transmission element includes a drive sprocket 30 mounted on one end of the drive rod 17 extending to the outside of the processing box 4, and a driven sprocket 31 mounted on one end of the stirring rod 29 extending to the outside of the cooling box 27. The drive sprocket 30 and the driven sprocket 31 are meshed together with a chain 32.

[0037] In this design, by setting up the drive sprocket 30, the driven sprocket 31 and the chain 32, the stirring rod 29 can be driven to rotate while the drive rod 17 rotates.

[0038] Specifically, the stirring rod 29 is rotated by the drive rod 17 without the need for an external power source. Furthermore, after cooling, the stirring rod 29 can be rotated externally.

[0039] like Figure 11 - Figure 12As shown, the sealing and fixing assembly includes a U-shaped block 34 installed on the top of the L-shaped base 1. Sliding holes are provided on the opposite inner walls of the U-shaped block 34. Sliding blocks 35 are slidably installed on the two sliding holes. Four sealing plates 36 are respectively installed on the top of the two sliding blocks 35. The side of the base plate 9 is provided with a placement groove that matches the sealing plate 36. Sliding plates 37 are installed at the ends of the two sliding blocks 35 that are far apart from each other. Trapezoidal blocks 39 are installed at the bottom of the two sliding plates 37. L-shaped fixing blocks 40 are installed on the two sides of the laser body 3 that are far apart from each other. Rollers are fixed at the ends of the two L-shaped fixing blocks 40. Two moving holes are provided on the side of the U-shaped block 34. Elastic units are provided on the side of the two sliding plates 37.

[0040] In this solution, by setting up U-shaped block 34, slider 35, sealing plate 36, sliding plate 37, trapezoidal block 39, L-shaped fixing block 40 and roller, the fixing hole 44 can be sealed after the laser body 3 is disassembled. At the same time, during installation, the sealing plate 36 can move to avoid the L-shaped fixing block 40 and then limit its position.

[0041] Specifically, by sealing the fixing hole 44, debris can be prevented from entering the processing box 4 and affecting subsequent use. The sealing plate 36 can be moved to avoid the L-shaped fixing block 40 and then limited, which facilitates the disassembly of the laser body 3 without the need to operate the sealing plate 36 and the laser body 3 separately.

[0042] like Figure 12 As shown, the elastic unit includes a spring 38 mounted on the side of the slide plate 37, and the other end of the spring 38 is mounted on the side wall of the U-shaped block 34.

[0043] In this design, the spring 38 facilitates the reset of the slide plate 37 when no force is applied.

[0044] Specifically, the sliding plate 37 resets when no force is applied, making it easy for the sealing plate 36 to move and seal the fixing hole 44 during disassembly. During installation, the L-shaped fixing block 40 is limited, thereby fixing the laser body 3.

[0045] like Figure 5 As shown, the surface of the heat dissipation fins 10 is serrated.

[0046] In this solution, by setting the surface of the heat dissipation fins 10 to a serrated shape, the heat dissipation area can be increased. When the coolant is sprayed onto the surface, the liquid is more likely to converge along the troughs or slopes of the serrations, forming a continuous stream, thereby accelerating the natural runoff of the coolant.

[0047] like Figure 1 and Figure 11 As shown, a guide block 2 is installed at the bottom of the laser body 3, and a guide groove is provided on the side of the L-shaped base 1.

[0048] In this design, the guide block 2 and the guide groove facilitate the guidance of the laser body 3.

[0049] Specifically, by guiding the laser body 3, it is easier for the laser body 3 to move in the horizontal direction, thus avoiding displacement when the L-shaped fixing block 40 squeezes the trapezoidal block 39.

[0050] The working principle of this device is as follows: Before use, coolant is poured into water tank 7, and then the laser body 3 is started. The output of the laser body 3 will emit laser light through the internal pump system and resonant cavity, thereby processing the product.

[0051] When the laser body 3 outputs, the heat inside is conducted out by the substrate 9 and diffused onto the heat sink fins 10. At this time, the first water pump 8 is activated, and the output of the first water pump 8 causes the coolant in the water tank 7 to be output into the output pipe 6. Then, the coolant in the output pipe 6 is discharged into the distribution cavity on the L-shaped threaded block 12 through the hose 5 and the water inlet. The coolant in the distribution cavity is discharged into multiple movable pipes 14 through the distribution hole and the rotary joint 15 and sprayed out from multiple nozzles. The coolant sprayed from the nozzles comes into contact with the heat sink fins 10 and then slides down quickly under the serrated surface of the heat sink fins 10. At the same time, the flow of coolant in the output pipe 6 will drive the vortex. Rotating wheel 18 causes turbine 18 to rotate, which in turn causes drive rod 17 to rotate. Drive rod 17 then causes incomplete bevel gear 19 and multiple drive bevel gears 24 to rotate. The rotation of incomplete bevel gear 19 drives driven bevel gear 20 to rotate intermittently. The intermittent rotation of driven bevel gear 20 causes reciprocating screw 11 to rotate intermittently. The intermittent rotation of reciprocating screw 11 causes L-shaped threaded block 12 to reciprocate intermittently. The intermittent reciprocating motion of L-shaped threaded block 12 causes L-shaped moving block 13 to reciprocate intermittently. The intermittent reciprocating motion of L-shaped moving block 13, through a rotating hole, causes movable tube 14 to reciprocate intermittently. The reciprocating motion causes the nozzle to move intermittently, resulting in the coolant contacting the heat sink fins 10 at different lateral positions. Simultaneously, the rotation of multiple drive bevel gears 24 drives multiple transmission bevel gears 23, which in turn rotate multiple movable rods 21. The rotation of these movable rods 21 causes the square rods 22 to rotate, which in turn, through square holes, causes multiple worm gears 25 to rotate. The rotation of these worm gears 25 then causes multiple worm wheels 26 to rotate, which in turn causes the movable tube 14 to rotate. The rotation of the movable tube 14 causes the nozzle to move in a circular motion. At this time, due to the symmetrical vertical staggered movement of the nozzle... When the setting is on, the circular motion of the nozzle will bring the coolant into contact with the heat dissipation fins 10 at different heights, resulting in different positions and heights of contact between the coolant and the heat dissipation fins 10. At this time, in combination with the gaps in the spray from the circular motion of the nozzle and the rapid sliding of the coolant, new coolant can be continuously brought into contact with the heat dissipation fins 10, thereby uniformly cooling the heat dissipation fins 10. At the same time, the coolant at the top, after dissipating heat from the heat dissipation fins 10, will be guided by the U-shaped guide plate 43, thereby preventing the coolant at the top from contacting the heat dissipation fins 10 at the bottom, thus preventing the used coolant from contacting the heat dissipation fins 10 and affecting cooling.

[0052] When the U-shaped guide plate 43 guides the coolant above, the coolant moves to the bottom of the treatment tank 4 through the drain hole 41 and the L-shaped drain cavity 42. At this time, the outlet pipe 28 containing the solenoid valve opens and closes periodically, thereby transferring the used coolant to the cooling tank 27. Simultaneously, the rotation of the drive rod 17 causes the drive sprocket 30 to rotate, which in turn causes the driven sprocket 31 to rotate along with the chain 32. The rotation of the driven sprocket 31 causes the stirring rod 29 to rotate, which mixes and stirs the coolant in the cooling tank 27 through the stirring blades, thereby pre-treating the coolant and effectively improving the subsequent cooling efficiency. After cooling, the cooled coolant can be discharged into the water tank 7 through the second water pump 33 and the connecting pipe for recycling.

[0053] When the laser body 3 needs to be disassembled, pulling the two sliding plates 37 causes the trapezoidal block 39 to move. When the trapezoidal block 39 is not in contact with the L-shaped fixing block 40, the L-shaped fixing block 40 is not limited. At this time, pulling the laser body 3 causes the heat sink fins 10 to move via the substrate 9. When the heat sink fins 10 are not in contact with the sealing plate 36, the L-shaped fixing block 40 is still in contact with the side of the trapezoidal block 39. When the L-shaped fixing block 40 is not in contact with the trapezoidal block 39, the sliding plate 37 is not under force. Under the action of the spring 38, the sliding plate 37 resets. The reset of the sliding plate 37 causes the slider 35 to reset, which in turn causes the sealing plate 36 to reset. The reset of the sealing plate 36 seals the fixing hole 44, thus preventing foreign objects from entering when the laser body 3 is disassembled and maintained. The laser body 3 moves horizontally through the guide block 2 and guide groove when the laser body 3 is replaced. When the roller on the L-shaped fixing block 40 contacts the trapezoidal block 39, the laser body 3 continues to move, causing the L-shaped fixing block 40 to squeeze the trapezoidal block 39 and move it. When the vertical surface of the trapezoidal block 39 contacts the L-shaped fixing block 40, the sealing plate 36 removes the seal on the fixing hole 44. Then the laser body 3 continues to move, causing the heat dissipation fins 10 to move into the processing box 4. When the L-shaped fixing block 40 moves to the other side of the trapezoidal block 39 and does not contact it, the trapezoidal block 39 will reset under the action of the spring 38. At this time, the sealing plate 36 is in the placement groove on the base plate 9, and the reset of the trapezoidal block 39 will limit the L-shaped fixing block 40, thereby fixing the laser body 3, which facilitates the disassembly and maintenance of the laser body 3 in the later stage.
