Description

Technical Field

[0001] The invention relates to the technical field related to water-guided lasers, and in particular to a micro-water flow laser coupling structure. Background Art

[0002] Water-guided laser technology is also known as micro-water jet laser technology or water jet guided laser technology. Its basic principle is to couple a high-power pulsed laser beam into a water jet and then act on the surface of the workpiece to achieve processing. At present, water-guided laser technology can be applied to the processing of core components composed of super-hard and brittle materials such as semiconductor materials, ceramics, cemented carbide and composite materials in cutting-edge fields such as new energy, smart grid, aerospace and electronic manufacturing. Compared with non-water-guided laser processing, water-guided laser processing has certain advantages. For example: 1. The cylindrical structure of the water jet can make the conducted laser output parallel, so the laser cutting surface is highly parallel and does not produce a slope; 2. The processing depth depends on the length of the water flow, which can exceed 10cm, and does not require an expensive focusing optical system; 3. Water-guided laser reduces the thermal damage of pulsed laser processing to the material and improves the uniformity of the cutting edge; 4. Because there is water on the processing surface, it effectively prevents the molten material from adhering to the processing surface after laser ablation; the huge advantages of water-guided laser processing are being transformed into huge large-scale application prospects.

[0003] In actual use of current water-guided laser technology, generally a high-power laser is output by fiber coupling, and is focused by a lens to a nozzle placed on a flat water chamber base. A columnar water jet ejected from the nozzle guides the laser to act on the surface of the workpiece. However, after the laser is focused into the water chamber, it is difficult to control the flow rate of the columnar water jet ejected through the water chamber, which makes it difficult to adjust the laser parameters by the water flow. In addition, the columnar water jet will produce a certain vibration during the processing of the workpiece. This tiny vibration may affect the stability of the laser in the water chamber, thereby directly affecting the processing quality of the workpiece. There is room for improvement. Summary of the invention

[0004] The purpose of the present invention is to provide a micro-water flow laser coupling structure to solve the problem mentioned in the above background technology that the current water-guided laser technology is difficult to adjust the laser parameters by controlling the water flow rate, and the vibration generated during the water jet processing may affect the stability of the laser.

[0005] To achieve the above-mentioned purpose, the present invention provides the following technical solutions: a micro-water flow laser coupling structure, comprising a positioning plate and a bottom plate, the upper surface of the positioning plate is fixedly connected with a laser component, the upper surface of the bottom plate is fixedly connected with a coupling component, the surface of the coupling component is connected with a water inlet pipe, the surface of the water inlet pipe is installed with a one-way valve, and the upper surface of the bottom plate is fixedly connected with a stabilizing component;

[0006] The laser component comprises a laser structure and a mapping structure, wherein the mapping structure is used to map the laser of the laser structure into the coupling component.

[0007] Preferably, the laser structure comprises a laser instrument, and the laser instrument is fixedly mounted on the upper surface of the positioning plate.

[0008] Preferably, the mapping structure includes an optical sleeve, which is an upper and lower open structure, the top of the optical sleeve is connected to the inside of the laser instrument, and the bottom of the optical sleeve is fixedly connected to a focusing mirror, and the position of the focusing mirror corresponds to the position of the coupling component.

[0009] Preferably, the coupling assembly includes a circular frame, a circular hole is provided on the upper surface of the circular frame, an optical window is fixedly connected to the inner wall of the circular hole, an inner frame is fixedly connected to the inner bottom wall of the circular frame, a water flow hole is provided on the upper surface of the inner frame, and a conical water outlet hole is provided on the lower surface of the inner frame at a position corresponding to the water flow hole.

[0010] Through the above scheme, when in use, the laser instrument can map the laser onto the focusing lens through the optical sleeve, and then the focusing lens directly guides the laser into the optical window. The laser directly passes through the water flow hole and the conical water outlet hole in the optical window to the surface of the workpiece, and the water flow will also be emitted to the surface of the workpiece in the water flow hole and the conical water outlet hole, thereby completing the coupled processing operation of laser and water flow.

[0011] Preferably, an arc-shaped baffle is fixedly connected to the upper surface of the inner frame, and a plurality of guide plates are fixedly connected to the upper surface of the inner frame, and a guide channel is formed between each guide plate, the guide channel corresponds to the water flow hole, and a pressure-stabilizing channel is formed between the outer surface of the inner frame and the inner wall of the circular frame. After the water flows into the circular frame, the pressure-stabilizing channel between the inner wall of the circular frame and the outer surface of the inner frame will be filled first. After filling, the water will flow into the water flow hole through the position of the guide plate. The arc-shaped baffle is provided to ensure that the water flows in a fixed channel in the circular frame, and there will be no turbulence problem, which will affect the processing quality.

[0012] Preferably, the outer surface of the inner frame is provided with two arc grooves, and the inner walls of the two arc grooves are inserted with arc top blocks, and a cavity is provided inside the inner frame, and the inner bottom wall of the cavity is fixedly connected with a double-axis motor, and the two output ends of the double-axis motor are fixedly connected with screw rods, and the ends of the two screw rods away from the double-axis motor are respectively rotatably connected to the left and right inner walls of the cavity, and the inner bottom wall of the cavity is slidably connected with two movable plates, and the two movable plates are respectively threaded with the two screw rods, and the opposite back surfaces of the two movable plates are fixedly connected with push rods, and the ends of the two push rods away from the movable plates extend into the inside of the two arc grooves respectively and are fixedly connected to the opposite back surfaces of the two arc top blocks. After the double-axis motor is started, it can drive the two screw rods to rotate synchronously, and the two screw rods drive the two movable plates to move toward the opposite back surfaces or opposite surfaces on the inner wall of the cavity. When the two movable plates move toward the opposite back surfaces, the two arc top blocks can be driven to extend out of the arc groove through the two push rods, and the space in the pressure stabilizing channel can be compressed, thereby increasing the water pressure and the water flow velocity at the conical water outlet, thereby changing the laser parameters, and the flexibility is high.

[0013] Through the above scheme, when in use, after water enters through the water inlet pipe, it will first fill the pressure stabilizing channel. When the pressure stabilizing channel is filled, the water flows through the unblocked position of the arc baffle, that is, the diversion channel formed by several guide plates, into the water flow hole position, and is discharged through the conical water outlet for cutting processing. The water flowing through the conical water outlet can guide the laser to directly act on the surface of the workpiece. The water flow can reduce the temperature of the workpiece surface when it is processed, and can also rinse the residue generated on the surface of the workpiece to ensure that it will not affect the normal processing operation. When it is necessary to adjust the laser parameters, turn on the dual-axis motor, the dual-axis motor drives the screw to rotate, thereby driving the two movable plates to move toward the opposite back sides, and the two movable plates drive the two arc-shaped top blocks to move into the pressure stabilizing channel through the two push rods, compressing the space in the pressure stabilizing channel, thereby increasing the water pressure and the flow rate, so as to adjust the laser parameters without adjusting the laser instrument, and the flexibility is high.

[0014] Preferably, the stabilizing assembly includes two first strip plates, which are fixedly connected to the upper surface of the base plate by four first bolts, and the upper surfaces of the two first strip plates are fixedly connected with a rectangular sleeve, and the left and right inner walls of the rectangular sleeve are provided with limiting grooves, and the inner bottom wall of the rectangular sleeve is fixedly connected with a driving motor, and the output end of the driving motor is fixedly connected with a threaded rod, and the top end of the threaded rod is fixedly connected with a limiting disk.

[0015] Preferably, the inner wall of the rectangular sleeve is slidably connected with a rectangular rod, and a screw hole is provided at the bottom end of the rectangular rod, and the rectangular rod is threadedly connected to the surface of the threaded rod through the screw hole, and the left and right sides of the rectangular rod are fixedly connected with limiting blocks, and the two limiting blocks are respectively slidably connected to the inner walls of the two limiting grooves, and the top of the rectangular rod is fixedly connected with a second strip plate, and the second strip plate is fixedly connected to the lower surface of the positioning plate through two second bolts. After the driving motor is started, it can drive the threaded rod to rotate. Since the bottom of the rectangular rod is threadedly connected to the threaded rod through the screw hole, the threaded rod can drive the rectangular rod to move up and down through the screw hole after rotation, and due to the blocking effect of the limiting plate, the rectangular rod will not separate from the surface of the threaded rod, and the rectangular rod will not separate from the inner wall of the rectangular sleeve due to the limiting effect of the two limiting blocks, so that the distance between the positioning plate and the bottom plate can be adjusted, and then the distance between the laser assembly and the coupling assembly can be adjusted. After the driving motor fails, the stabilizing assembly can also be removed through the first strip plate, the first bolt, the second strip plate and the second bolt, which is convenient for rapid replacement of the driving motor and more convenient to use.

[0016] Through the above scheme, when in use, the driving motor is turned on, the driving motor can drive the threaded rod to rotate, and the threaded rod drives the rectangular rod to move up and down in the rectangular sleeve through the screw hole on the lower surface of the rectangular rod. Since a limit plate is arranged on the top of the threaded rod, the rectangular rod will not separate from the surface of the threaded rod. During the up and down movement of the rectangular rod, the distance between the positioning plate and the bottom plate can be adjusted, thereby changing the distance between the laser assembly and the coupling assembly, thereby changing the laser parameters and further improving the flexibility of the device. The rectangular sleeve is fixedly connected to the bottom plate by the first strip plate and the first bolt, and the rectangular rod is fixedly connected to the positioning plate by the second strip plate and the second bolt, thereby ensuring the stability of the coupling assembly during the processing, reducing the influence of the vibration generated during water jet cutting on the laser assembly, improving the processing stability, and thus ensuring the forming quality of the workpiece.

[0017] Compared with the prior art, the beneficial effects of the present invention are as follows: the micro-water flow laser coupling structure, through the setting of the coupling component, can drive the two screws to rotate through the dual-axis motor when in use, thereby driving the two movable plates to move toward opposite backs, and then driving the two arc-shaped top blocks through the two top rods to reduce the space in the pressure stabilizing channel, thereby increasing the water pressure, increasing the water flow velocity in the conical water outlet, and changing the laser parameters by changing the flow velocity of the water flow, thereby further improving the precision processing of the workpiece, and at the same time reducing the difficulty of laser parameter modification, with higher flexibility, and the stabilizing component can fix the positioning plate and the bottom plate to be connected, thereby reducing the influence of the vibration generated during water flow cutting on the laser, further improving the processing quality of the workpiece, and when the driving motor is damaged, the stabilizing component can also be quickly removed from the positioning plate and the bottom plate through the first strip plate, the first bolt, the second strip plate and the second bolt, so as to quickly replace the stabilizing component.

[0031] Furthermore, the mapping structure 32 includes an optical sleeve 3201, which is an upper and lower open structure. The top of the optical sleeve 3201 is connected to the interior of the laser instrument 3101, and the bottom of the optical sleeve 3201 is fixedly connected with a focusing mirror 3202, and the position of the focusing mirror 3202 corresponds to the position of the coupling component 4.

[0033] Through the above scheme, when in use, the laser instrument 3101 can map the laser onto the focusing lens 3202 through the optical sleeve 3201, and then the focusing lens 3202 directly guides the laser to the optical window 402. The laser is directly emitted to the surface of the workpiece through the water flow hole 404 and the conical water outlet hole 405 in the optical window 402, and the water flow will also be emitted to the surface of the workpiece in the water flow hole 404 and the conical water outlet hole 405, thereby completing the coupled processing operation of laser and water flow.

[0034] Furthermore, an arc-shaped baffle 406 is fixedly connected to the upper surface of the inner frame 403, and a plurality of guide plates 407 are fixedly connected to the upper surface of the inner frame 403, and a guide channel is formed between each guide plate 407, and the guide channel corresponds to the water flow hole 404, and a pressure stabilizing channel 408 is formed between the outer surface of the inner frame 403 and the inner wall of the circular frame 401.

[0035] Furthermore, two arc grooves are provided on the outer surface of the inner frame 403, and arc top blocks 409 are inserted into the inner walls of the two arc grooves, and a cavity is provided inside the inner frame 403, and a dual-axis motor 410 is fixedly connected to the inner bottom wall of the cavity, and two output ends of the dual-axis motor 410 are fixedly connected to screw rods 411, and the ends of the two screw rods 411 away from the dual-axis motor 410 are rotatably connected to the left and right inner walls of the cavity, respectively, and two movable plates 412 are slidably connected to the inner bottom wall of the cavity, and the two movable plates 412 are respectively threadedly connected to the two screw rods 411, and the opposite back surfaces of the two movable plates 412 are fixedly connected to top rods 413, and the ends of the two top rods 413 away from the movable plates 412 extend to the inside of the two arc grooves, respectively, and are fixedly connected to the opposite back surfaces of the two arc top blocks 409;

[0036] Through the above scheme, when in use, after water enters through the water inlet pipe 5, it will first fill the pressure stabilizing channel 408. When the pressure stabilizing channel 408 is filled, the water flows through the unblocked position of the arc baffle 406, that is, the guide channel position formed by a plurality of guide plates 407, into the water flow hole 404 position, and is discharged through the conical water outlet hole 405 for cutting processing. The water flowing through the conical water outlet hole 405 can guide the laser to directly act on the workpiece surface. The water flow can reduce the temperature of the workpiece surface when it is processed, and can also produce The raw residue is rinsed clean to ensure that it will not affect the normal processing operation. When the laser parameters need to be adjusted, the dual-axis motor 410 is turned on. The dual-axis motor 410 drives the screw 411 to rotate, thereby driving the two movable plates 412 to move toward opposite sides. The two movable plates 412 drive the two arc-shaped top blocks 409 to move into the pressure-stabilizing channel 408 through the two top rods 413, compressing the space in the pressure-stabilizing channel 408, thereby increasing the water pressure and the flow rate, so as to adjust the laser parameters. There is no need to adjust the laser instrument 3101, and it is more flexible.

[0037] It is worth noting that since a one-way valve 6 is provided on the surface of the water inlet pipe 5, there will be no backflow problem after the water flows through the water inlet pipe 5 into the pressure stabilizing channel 408, and after the pressure in the pressure stabilizing channel 408 increases, the water will not flow back, but the water flow rate at the position of the conical water outlet 405 will increase.

[0038] Furthermore, the stabilizing assembly 7 includes two first strip plates 701, which are fixedly connected to the upper surface of the base plate 2 by four first bolts 702, and the upper surfaces of the two first strip plates 701 are fixedly connected with a rectangular sleeve 703, and the left and right inner walls of the rectangular sleeve 703 are provided with limiting grooves, and the inner bottom wall of the rectangular sleeve 703 is fixedly connected with a driving motor 704, and the output end of the driving motor 704 is fixedly connected with a threaded rod 705, and the top end of the threaded rod 705 is fixedly connected with a limiting disk 706.

[0039] Furthermore, a rectangular rod 707 is slidably connected to the inner wall of the rectangular sleeve 703, a screw hole is provided at the bottom end of the rectangular rod 707, and the rectangular rod 707 is threadedly connected to the surface of the threaded rod 705 through the screw hole, and the left and right sides of the rectangular rod 707 are fixedly connected to limit blocks 708, and the two limit blocks 708 are respectively slidably connected to the inner walls of the two limit grooves, and the top of the rectangular rod 707 is fixedly connected to a second strip plate 709, and the second strip plate 709 is fixedly connected to the lower surface of the positioning plate 1 through two second bolts 710;

[0040] Through the above scheme, when in use, the driving motor 704 is turned on, and the driving motor 704 can drive the threaded rod 705 to rotate, and the threaded rod 705 drives the rectangular rod 707 to move up and down in the rectangular sleeve 703 through the screw hole on the lower surface of the rectangular rod 707. Since a limit plate 706 is set on the top of the threaded rod 705, the rectangular rod 707 will not be separated from the surface of the threaded rod 705. During the up and down movement of the rectangular rod 707, the distance between the positioning plate 1 and the bottom plate 2 can be adjusted, thereby changing the distance between the laser component 3 and the coupling component 4, which can change the laser parameters and further improve the flexibility of the device. The rectangular sleeve 703 is fixedly connected to the bottom plate 2 through the first strip plate 701 and the first bolt 702, and the rectangular rod 707 is fixedly connected to the positioning plate 1 through the second strip plate 709 and the second bolt 710, which can ensure the stability of the coupling component 4 during the processing process, and reduce the influence of the vibration generated during water jet cutting on the laser component 3, thereby improving the processing stability, and thus ensuring the forming quality of the workpiece.

[0041] Working principle: first, move the bottom plate 2 to the position above the workpiece to be processed, turn on the laser instrument 3101, the laser instrument 3101 emits laser and maps the laser through the optical sleeve 3201 to the focusing lens 3202, guide the laser into the optical window 402 through the focusing lens 3202, and then align it with the water flow hole 404 through the optical window 402. At this time, open the one-way valve 6, and water enters the pressure-stabilizing channel 408 inside the circular frame 401 through the water inlet pipe 5. When the pressure-stabilizing channel 408 is filled, the water will pass through the position not blocked by the arc baffle 406 and pass through if The water flows into the water hole 404 in the guide channel formed by the guide plates 407 and is ejected through the conical water outlet hole 405. At this time, the laser can be coupled with the water flow, and the water flow ejected from the conical water outlet hole 405 guides the laser to act on the surface of the desired workpiece to complete the processing operation, which can not only ensure the processing quality of the workpiece, but also can rinse the incision on the surface of the workpiece, reduce the temperature of the workpiece at the processing position, and avoid burrs and other structures affecting the molding quality. When it is necessary to adjust the laser parameters, first turn on the dual-axis motor 410 so that the dual-axis motor 410 drives The two screw rods 411 are driven to rotate, and the two screw rods 411 can drive the two movable plates 412 to move toward opposite sides. At this time, the two movable plates 412 can drive the two arc-shaped top blocks 409 to move into the pressure-stabilizing channel 408 through the two top rods 413, thereby compressing the space in the pressure-stabilizing channel 408, thereby increasing the pressure in the pressure-stabilizing channel 408 and increasing the water flow rate, so as to adjust the laser parameters. At the same time, the two driving motors 704 are turned on to rotate the threaded rod 705, which drives the rectangular rod 707 to descend, thereby driving the laser component 3 to approach the coupling component 4, and further The adjustment of laser parameters is improved, and the flexibility is higher. The laser component 3 and the coupling component 4 are connected by two stabilizing components 7, which can ensure that during the processing, the laser will not be affected by the vibration caused by the excessive water flow velocity, further increasing the processing stability and ensuring the processing quality. When the drive motor 704 is damaged, the stabilizing component 7 can also be quickly removed from the positioning plate 1 and the base plate 2 through the first strip plate 701, the first bolt 702, the second strip plate 709 and the second bolt 710, so as to quickly replace the stabilizing component 7.
