Description

Technical Field

[0001] The present invention relates to the field of laser technology, and more particularly to a laser with high beam quality. Background Art

[0002] Beam quality is an important indicator for measuring laser performance. A laser with high beam quality usually means that its output beam has a small divergence angle, a good spot mode (such as a close to ideal Gaussian beam) and a high beam brightness. For lasers with high beam quality, effective heat control is crucial. If the heat cannot be dissipated in time, it will cause the temperature of components such as the gain medium in the laser body to change, such as producing a thermal lens effect, making the refractive index distribution uneven. This will change the oscillation mode of the laser in the resonant cavity, resulting in an increase in the beam divergence angle and a deterioration in the spot mode, thereby reducing the beam quality and affecting the application effect of the laser in fields such as material processing (reduced cutting and welding accuracy), medical treatment (affected surgical accuracy), and communication (reduced signal coupling and transmission quality).

[0003] The traditional high beam quality laser cooling method usually simply uses a heat conduction plate to conduct the heat away. The more complicated method is to open a cooling tank on the basis of the heat conduction plate, and use the dynamic circulation of water flow to take away the heat inside the cooling tank or neutralize the heat and cold to achieve cooling. However, as the above method is used for a long time, the inner wall of the cooling tank may accumulate dust, dirt and other impurities due to chemical reactions or impurities in the water source. These impurities will hinder the conduction of heat, further reduce the cooling effect, and indirectly affect the stability of the beam quality. Therefore, we designed a high beam quality laser.

[0014] The beneficial effects of the present invention are: 1. The laser with high beam quality described in the present invention can transport the coolant in the cooling tank to the inside of the cooling tank through a water pump to form a dynamic cycle, thereby achieving a continuous cooling effect. In the process, the driving force generated by the liquid flow will cause the cleaning ring located inside the cooling tank to continuously swing inside the cooling tank. Since the cleaning ring is in contact with the inner wall of the cooling tank, the cooling tank can be cleaned to prevent impurities from adhering to the inside of the cooling tank to reduce its heat conduction, thereby affecting the cooling of the laser body and affecting the beam quality of the laser body.

[0015] 2. The high beam quality laser described in the present invention uses a driving force generated by the coolant delivered by a water pump to cause the extrusion plate to continuously reciprocate. The movement of the extrusion plate will continuously squeeze the extrusion frame, so that the extrusion frame will drive the latch teeth to act on the second gear. The rotation of the second gear will cause the second reciprocating screw to rotate, thereby causing the second threaded plate to reciprocate. In this way, the second threaded plate can squeeze the coolant little by little into the fixed half-tube and the rubber half-tube, and can effectively expand the rubber half-tube little by little. In this way, when cleaning the cooling tank, the cleaning wiping ring can clean the impurities in the cooling tank layer by layer, and the expansion of the rubber half-tube can make the cleaning wiping ring clean the cooling tank more effectively.

[0016] 3. The laser with high beam quality described in the present invention, through the continuous swing of the driving tube, the limit tube and the limit rod connected to the driving tube will also swing accordingly. When the limit rod swings to the specified position, the limit rod will be squeezed with the limit plate, so that the blocking plate moves. When the blocking plate is separated from the fixed ring, the driving tube drives its swinging process to only push a part of the coolant in the hollow tube to be transported to the inside of the cooling tank. When the blocking plate is plugged into the fixed ring, the driving tube drives its swinging process to push all the coolant in the hollow tube to be transported to the inside of the cooling tank, thereby effectively controlling the water flow speed. The fast and slow water flow speed can produce different degrees of flushing effect on the cooling tank, reducing the adhesion of impurities. BRIEF DESCRIPTION OF THE DRAWINGS

[0021] It should be noted that a filter cover is installed at the water inlet end of the water pump 402; when the water pump 402 is started, the water pump 402 will extract the coolant in the cooling box 401 into the second liquid infusion pipe 422, and the coolant entering the second liquid infusion pipe 422 will enter the hollow turntable 408 and impact the impeller 414, causing the impeller 414 to rotate, and the coolant after impacting the impeller 414 will enter the hollow tube 406 through the first and second liquid infusion pipes 422, and be transported to the cooling tank 3, thereby taking away the heat in the heat conduction plate 2, achieving a cooling effect; The rotation of the impeller 414 will drive the third rotating shaft 507 to rotate, the third rotating shaft 507 will drive the worm 407 to rotate, the worm 407 will drive the worm wheel 420 to rotate, the worm wheel 420 will drive the first reciprocating screw 416 to rotate, the first reciprocating screw 416 will drive the first threaded plate 417 to move back and forth, the movement of the first threaded plate 417 will drive the rack 410 to move back and forth, the reciprocating movement of the rack 410 will cause the first gear 413 to rotate forward and reverse, so that the rotating tube 404 connected to the first gear 413 will swing forward and reverse, and the rotating tube 404 is connected to the cleaning ring 601, which is in contact with the cooling tank 3, so that the cleaning ring 601 can continuously swing back and forth inside the cooling tank 3 to clean the cooling tank 3, so as to prevent the cooling tank 3 from being covered by impurities and affecting heat conduction and heat dissipation.

[0022] like Figure 12 to Figure 13 As shown, a pressurizing mechanism is fixedly connected to the inner wall of the bottom of the inner cavity of the cooling box 401; the pressurizing mechanism includes an extrusion plate 418, and the extrusion plate 418 is fixedly connected to the first threaded plate 417; the pressurizing mechanism also includes a fixed box 506, and an extrusion frame 504 is provided on the fixed box 506, and a slide plate 508 is fixedly connected to the bottom of the extrusion frame 504, and the slide plate 508 is slidably connected to the fixed box 506, and the bottom of the slide plate 508 is connected to the fixed box 506 through a first spring 509, and a latch 505 is fixedly connected to the extrusion frame 504, and a pressurizing component is meshed on the latch 505, and the pressurizing component is located inside the fixed box 506 and is rotatably connected to the fixed box 506, and a third infusion tube 501 is fixedly connected to the fixed box 506, and the third infusion tube 501 is connected with the rotating sleeve 412; the pressurizing component includes 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, a second gear 511 is fixedly connected to the connecting column 510, the second gear 511 is meshed with the latch tooth 505, a tooth groove is penetrated through the second gear 511, a driving disk 513 is arranged inside the tooth groove, a paddle plate 512 is installed on one side of the driving disk 513, a second reciprocating screw rod 502 is fixedly connected to the other side of the driving disk 513, the second reciprocating screw rod 502 is rotatably connected with the fixed box 506, a second threaded plate 503 is threadedly connected to the second reciprocating screw rod 502, and the second threaded plate 503 is slidably connected with the fixed box 506.

[0023] It should be noted that when the first threaded plate 417 continuously moves back and forth, the first threaded plate 417 also drives the extrusion plate 418 to move back and forth, and the reciprocating movement of the extrusion plate 418 will intermittently squeeze the extrusion frame 504, and the extrusion frame 504 will drive the latching tooth 505 to move downward after being squeezed, and the latching tooth 505 acts on the second gear 511 to rotate the second gear 511, and the rotation of the second gear 511 will drive the driving disk 513 to rotate through the toggle plate 512, and the driving disk 513 will drive the second reciprocating screw rod 502 to rotate, and the second reciprocating screw rod 502 will rotate. The rotation of the second threaded plate 503 will drive the second threaded plate 503 to move, 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 infusion tube 501, and then transported 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, so that the cleaning ring 601 is more closely in contact with the cooling tank 3, which can achieve a better cleaning effect; And each time the extrusion frame 504 moves the second threaded plate 503 for a distance, the first spring 509 returns 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, thereby avoiding excessive accumulation of impurities and the phenomenon that they cannot be washed out by the water flow.

[0024] 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, a connecting frame 706 is fixedly connected to the fixing ring 701, a press-rebound assembly is fixedly connected to the connecting frame 706, a blocking plate 705 is fixedly connected to the press-rebound assembly, and the blocking plate 705 is plugged with 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, an installation box 708 is fixedly connected inside the limiting tube 702, and the installation 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 penetrates 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 opened on the slider 710, and an auxiliary rod 709 is arranged 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.

[0025] It should be noted that when the driving tube 403 is continuously rotating, the driving tube 403 will also drive the fixing ring 701 and the blocking plate 705 to move. Since there is also cooling liquid in the hollow tube 406, the blocking plate 705 is plugged with the fixing ring 701 at this time, so that during the movement, all the cooling liquid in the hollow tube 406 can be discharged into the cooling tank 3, so that the flow rate of the cooling liquid in the cooling tank 3 is accelerated, which can accelerate the heat dissipation and achieve a better cooling effect. However, when the fixing ring 701 moves to the specified position, the limit rod 707 on the fixing ring 701 will squeeze the limit plate 704 against each other. At this time, the limit rod 707 will drive the slider 710 to move. The slider 710 will move the auxiliary rod 709 and the rotating plate 712 due to the track groove 713, and under the action of the second spring 711, the sliding rod 415 will drive the blocking plate 705 away from the fixing ring 701. In this way, when the fixing ring 701 and the blocking plate 705 drive the coolant in the hollow tube 406 to enter the cooling tank 3 again, the amount of coolant will become less and its water pressure will also decrease. In this way, the coolant flowing in the cooling tank 3 will be faster and slower. The fast and slow water flow speed can produce different degrees of flushing effect on the cooling tank 3 and reduce the adhesion of impurities.

[0026] The above describes an embodiment of the present invention, but this embodiment is not limited to the above specific implementation methods. The above specific implementation methods are merely illustrative and not restrictive. Under the guidance of this embodiment, ordinary technicians in this field can also make many forms, all of which are protected by this embodiment.
