Description

TECHNICAL FIELD

[0002] Beam quality is an important indicator to measure the performance of laser. High beam quality laser generally refers to its output beam has a small divergence angle, better spot pattern (such as close to ideal Gaussian beam) and higher beam brightness. For high beam quality laser, effective control of heat is crucial. If the heat cannot be removed in time, the temperature of the gain medium and other components in the laser body will change, for example, thermal lens effect occurs, making the refractive index distribution uneven. This will change the oscillation mode of the laser in the resonant cavity, resulting in increased beam divergence angle, poor spot pattern, thereby reducing the beam quality and affecting the application effect of the laser in the fields such as material processing (cutting, welding precision is reduced), medical treatment (surgical precision is affected), communication (signal coupling and transmission quality is reduced) and the like.

[0034] It needs explanation that the water inlet end of the water pump 402 is provided with a filter cover; the water pump 402 is started, the water pump 402 will pump the cooling liquid in the cooling tank 401 into the second liquid conveying pipe 422, the cooling liquid in the second liquid conveying pipe 422 will enter the hollow rotating disc 408 and impact the impeller 414, so that the impeller 414 rotates, and the cooling liquid after impacting the impeller 414 will enter the hollow pipe 406 through the first second liquid conveying pipe 422 and be conveyed to the cooling tank 3, so as to take away the heat in the heat-conducting plate 2 and achieve the effect of cooling;

[0035] The rotation of the impeller 414 drives the third rotating shaft 507 to rotate, the third rotating shaft 507 drives the worm 407 to rotate, the worm 407 drives the worm wheel 420 to rotate, the worm wheel 420 drives the first reciprocating lead screw 416 to rotate, the first reciprocating lead screw 416 drives the first threaded plate 417 to reciprocate, the reciprocation of the first threaded plate 417 drives the rack 410 to reciprocate, and the reciprocation of the rack 410 drives the first gear wheel 413 to rotate in opposite directions, so that the rotating pipe 404 connected with the first gear wheel 413 swings in opposite directions, the rotating pipe 404 is provided with a cleaning wiper ring 601, the cleaning wiper ring 601 is in contact with the cooling tank 3, and the cleaning wiper ring 601 can reciprocate in the cooling tank 3 to clean the cooling tank 3, so as to avoid that the cooling tank 3 is covered with impurities and affects heat conduction and heat dissipation.

[0036] As shown in Figures 12 to 13 The bottom inner wall of the inner cavity of the cooling tank 401 is fixedly connected with a pressing mechanism; the pressing mechanism comprises an extrusion plate 418, and the extrusion plate 418 is fixedly connected with the first threaded plate 417; the pressing mechanism further comprises a fixed box 506, the extrusion frame 504 is penetratingly arranged on the fixed box 506, the sliding plate 508 is fixedly connected to the bottom of the extrusion frame 504, the sliding plate 508 is slidingly connected with the fixed box 506, the first spring 509 is connected between the bottom of the sliding plate 508 and the fixed box 506, the clamping tooth 505 is fixedly connected to the extrusion frame 504, the clamping tooth 505 is engaged with a pressing assembly, the pressing assembly is located in the fixed box 506 and is rotatably connected with the fixed box 506, the third liquid conveying pipe 501 is fixedly connected to the fixed box 506 and communicates with the rotating sleeve 412; the pressing assembly comprises a third rotating shaft 507, the third rotating shaft 507 is rotatably connected with the fixed box 506, a plurality of connecting columns 510 are fixedly connected to the third rotating shaft 507, the second gear wheel 511 is fixedly connected to the connecting columns 510, the second gear wheel 511 is engaged with the clamping tooth 505, the tooth groove is penetratingly arranged on the second gear wheel 511, the driving disc 513 is arranged in the tooth groove, the driving disc 513 is provided with the driving piece 512 on one side, the second reciprocating lead screw 502 is fixedly connected to the other side of the driving disc 513 and rotatably connected with the fixed box 506, the second threaded plate 503 is threadedly connected to the second reciprocating lead screw 502 and slidingly connected with the fixed box 506.

[0037] It should be noted that when the first threaded plate 417 continuously moves back and forth, the first threaded plate 417 will also drive the extrusion plate 418 to move back and forth. The reciprocating movement of the extrusion plate 418 will intermittently squeeze the extrusion frame 504. After the extrusion frame 504 is squeezed, it will drive the latch 505 to move down. The latch 505 acts on the second gear 511 to rotate the second gear 511. The rotation of the second gear 511 will drive the driving plate 513 to rotate through the toggle piece 512. The driving plate 513 drives the second reciprocating screw rod 502 to rotate. The second reciprocating screw rod 502 is rotated. The rotation of the second threaded plate 503 will drive the movement of the second threaded plate 503, so that the second threaded plate 503 will squeeze or release the coolant in the fixed box 506, so that the coolant is transported to the rotating tube 404 through the third liquid delivery tube 501, and then from the rotating tube 404 to the driving tube 403, and finally transported to the fixed half tube 604 through the connecting tube 602. Due to the addition of coolant, the rubber half tube 603 will be squeezed and expanded. In this way, the cleaning ring 601 is cooled and more closely contacts the cooling tank 3, which can achieve a better cleaning effect.

[0038] And each time the extrusion frame 504 moves the second threaded plate 503 for a distance, the first spring 509 will return to its original position, making it convenient to continue driving the second threaded plate 503. In this way, the moving distance of the second threaded plate 503 is fixed, and the degree of expansion of the rubber half-tube 603 will also be layer by layer. Finally, the cleaning ring 601 can clean the impurities in the cooling tank 3 layer by layer. Cleaning layer by layer can not only clean the impurities more finely, but also ensure that the impurities cleaned out each time are not much and can be flushed out by the coolant, avoiding the accumulation of excessive impurities and the phenomenon that they cannot be carried out by the water flow.

[0039] like Figures 6 to 11 As shown, the opening and closing mechanism includes a first connecting plate 703, a fixing ring 701 is fixedly connected to the first connecting plate 703, the fixing ring 701 is slidably connected to the hollow tube 406, the fixing ring 701 is fixedly connected to the connecting frame 706, the connecting frame 706 is fixedly connected to a press-rebound assembly, the press-rebound assembly is fixedly connected to a blocking plate 705, and the blocking plate 705 is plugged into the fixing ring 701; the press-rebound assembly includes a limiting tube 702, the limiting tube 702 is fixedly connected to the connecting frame 706, the limiting tube 702 is fixedly connected to the interior of the limiting tube 708, and the mounting box 708 is fixedly connected to the mounting box A slider 710 is slidably connected inside 708, and a limiting rod 707 is fixedly connected to the slider 710. The limiting rod 707 passes through the limiting tube 702 and is slidably connected to the limiting tube 702. The limiting rod 707 is fixedly connected to the blocking plate 705. A second spring 711 is fixedly connected to the slider 710, and the second spring 711 is fixedly connected to the installation box 708. A track groove 713 is provided on the slider 710, and an auxiliary rod 709 is provided in the track groove 713. A rotating plate 712 is rotatably connected to the auxiliary rod 709, and the rotating plate 712 is rotatably connected to the installation box 708.

[0040] It should be noted that when the drive pipe 403 rotates continuously, the drive pipe 403 also drives the fixed ring 701 and the blocking plate 705 to move, since the hollow pipe 406 also has cooling liquid, at this time the blocking plate 705 is inserted with the fixed ring 701, so that in the moving process, all the cooling liquid in the hollow pipe 406 can be discharged into the cooling tank 3, so as to accelerate the flow rate of the cooling liquid in the cooling tank 3, so as to accelerate the heat dissipation, and better play the cooling effect;

[0041] But when the fixed ring 701 moves to the specified position, the limiting rod 707 on the fixed ring 701 will be extruded with the limiting plate 704, at this time, the limiting rod 707 will drive the sliding block 710 to move, the sliding block 710 will make the auxiliary rod 709 and the rotating plate 712 move due to the track groove 713, and under the action of the second spring 711, the sliding rod 415 drives the blocking plate 705 to move away from the fixed ring 701, so that when the fixed ring 701 and the blocking plate 705 drive the cooling liquid in the hollow pipe 406 to enter the cooling tank 3 again, the amount of the cooling liquid will be less, and the water pressure will also be reduced, so that the cooling liquid flowing in the cooling tank 3 will be fast and slow, and the fast and slow of the water flow rate can produce different degrees of scouring effect on the cooling tank 3, and reduce the attachment of impurities.
