Description

Technical Field

[0001] The present invention relates to the technical field related to laser debugging, and specifically provides a laser optical axis debugging device and a debugging method. Background Technique

[0002] A laser is a device that uses the principle of stimulated emission to generate a beam with high intensity, high directivity, high monochromaticity, and high coherence. Its core function is to convert energy into laser of a specific wavelength, and it is widely used in fields such as communication, medical treatment, and industrial processing.

[0003] In the application of laser technology, the accurate debugging of the laser optical axis is crucial. The deviation of the optical axis will cause the direction and position of the laser output not to meet the requirements, affecting the accuracy and effect of applications such as laser processing and measurement. Most of the existing laser optical axis debugging devices adjust the vertical and horizontal positions of the laser through separate adjustment mechanisms, with a relatively complex structure and a cumbersome debugging process. When adjusting the deflection and pitch angles of the optical axis, usually, an optical axis adjustment rod is used to turn three adjustment screws respectively to adjust the pitch and deflection angles of the optical axis, with relatively low adjustment efficiency and inconvenient use. Moreover, during the debugging process, the existing devices have a cumbersome clamping and fixing of the laser, reducing the efficiency of laser debugging. Summary of the Invention

[0008] As a preferred technical solution of the present invention, the fine adjustment assembly includes two threaded sleeves rotatably installed on the left and right sides of the mounting plate. Fine adjustment screws are threadedly installed in the two threaded sleeves. One end of the fine adjustment screw close to the mounting seat is fixedly installed with an elastic rubber cap. A universal ball head is fixedly installed on the elastic rubber cap. The universal ball head is universally hinged to the mounting seat through a ball cap fixedly installed on the mounting seat. The outer surface of the threaded sleeve is fixedly installed with a worm gear. A worm meshing with the worm gear is rotatably installed on the mounting plate. One end of the worm is fixedly connected to the output end of a micro motor provided on the mounting plate.

One end of the support rod is fixedly installed with a second universal ball. The mounting seat is fixedly installed with a second ball socket for cooperating with the second universal ball. The support rod is located on the perpendicular bisector of the line connecting the two fine adjustment screws.

[0010] As a preferred technical solution of the present invention, the clamping assembly includes a second electric push rod fixedly installed in the mounting seat. The output end of the second electric push rod is fixedly installed with a wedge-shaped frame. The two sides of the wedge-shaped frame have wedge-shaped parts, and the wedge-shaped parts on both sides are symmetrically inclined. Moving blocks are slidably installed on both sides of the mounting seat. First clamping plates are fixedly installed on the opposite surfaces of the two moving blocks and on the wedge-shaped frame. A placement plate is fixedly installed on the mounting seat. Clamping air bags are fixedly installed on the first clamping plates. Wedge-shaped grooves for cooperating with the wedge-shaped parts are opened on the two moving blocks. The moving blocks are slidably connected to the wedge-shaped parts on the same side.

[0011] As a preferred technical solution of the present invention, the clamping airbag is composed of a clamping part and side wall airbags connected to both ends of the clamping part. The side wall airbags are concave circular arcs, and the thickness of the side wall airbags gradually decreases towards the clamping part.

[0012] As a preferred technical solution of the present invention, an arc-shaped support pad is arranged on the placement plate.

[0013] As a preferred technical solution of the present invention, a limiting groove is opened on the fine adjustment screw rod, and a limiting rod for cooperating with the limiting groove is opened on the mounting plate.

[0014] A method for debugging the optical axis of a laser, applied to a laser optical axis debugging device in the above technical solution, includes the following steps: S1: Place the laser on the placement plate, drive the second electric push rod to clamp and fix the laser, and then turn on the power supply of the laser to make it emit a laser beam; S2: Set a target at the position on the light-emitting path of the laser. A cross center line and scale lines are drawn on the target. S3: By controlling the coordinated use of the two first electric push rods, adjust the vertical height and horizontal position of the mounting seat so that the position where the laser beam irradiates on the target is near the center of the target, and complete the rough adjustment of the laser beam. S4: Drive the two micro motors to drive the fine adjustment screw rods to rotate respectively. Through the mutual cooperation of the two micro motors, the laser spot gradually moves towards the center of the target. During the adjustment process, the adjustment amounts of the pitching angle and yaw angle are accurately controlled through the scale lines until the laser spot is completely located at the center of the target, and the precise debugging of the laser optical axis is completed.

[0015] The beneficial effects of the present invention are: 1. For this kind of laser optical axis debugging device and debugging method, by setting the rough adjustment component, the telescopic movement of the first electric push rod drives the slider on the same side to move in the chute, and under the cooperation of the first universal ball and the first ball sleeve, the connecting rod will be driven to deflect. The deflection of the connecting rod drives the connecting ball to move in the ring sleeve, and the ring sleeve is used to push the mounting frame or the mounting plate to move, that is, the horizontal and vertical positions of the mounting seat and the laser therein can be adjusted. Thus, through the coordinated use of the two first electric push rods, the mounting seat can be adjusted to any position in the horizontal and vertical directions at the same time, so that the position where the laser beam irradiates on the target is near the center of the target, and the rough adjustment of the laser optical axis is completed. The operation is simple and convenient, without the need for the operator to perform multiple repeated adjustments and measurements, and the debugging efficiency is high.

[0016] 2. For this laser optical axis debugging device and debugging method, by setting the fine-tuning component, the micro-motor drives the threaded sleeve to rotate through the worm. The rotation of the threaded sleeve drives the elastic rubber cap to move, and drives the mounting seat and the laser inside it to deflect under the cooperation of the universal ball head and the ball cap, that is, the pitching and deflection angles of the laser optical axis can be adjusted. Thus, through the combined use of two micro-motors, the pitching angle and yaw angle of the mounting seat and the laser can be accurately adjusted, realizing the precise debugging of the laser optical axis. The operation is simple and convenient to use. Compared with the traditional method of repeatedly turning the adjustment screw to adjust the pitching and deflection angles of the optical axis, it has the characteristics of simple operation, convenient use, good stability and high adjustment efficiency.

[0017] 3. For this laser optical axis debugging device and debugging method, by setting the clamping component, pushing the wedge-shaped frame downward through the second electric push rod can drive the three first clamping plates and the clamping air bags on them, and cooperate with the placement plate to quickly clamp and fix the laser, ensuring the stability of the laser during debugging. The structure is simple and convenient to use, facilitating the quick clamping of the laser, improving the efficiency of laser debugging, and being convenient for clamping and fixing lasers of different sizes, with a wide application range and strong practicability.

[0018] 4. For this laser optical axis debugging device and debugging method, by setting the clamping air bag, when the first clamping plate and the clamping air bag clamp and fix the laser, the pressure on the clamping part causes the gas in the clamping part to flow into the side wall air bag, and the pressure in the side wall air bag increases. Since the thickness of the side wall air bag gradually becomes smaller on the side of the clamping part, the multi-layer telescopic folds on the side wall air bag can be fully unfolded, increasing the contact area between the side wall air bag and the laser, facilitating adaptation to different curved surfaces of the laser, and at the same time increasing the friction between the side wall air bag and the laser, improving the stability when clamping and fixing the laser.

Detailed implementation mode

[0021] The following is a description of the preferred embodiments of the present invention with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are only used to illustrate and explain the present invention and are not used to limit the present invention.

[0022] Embodiment: As Figures 1 to 9 shown, a laser optical axis debugging device of the present invention includes a workbench 1 and a frame 2 and a control panel 11 arranged on the workbench 1, and further includes: Guide rail 3: The guide rail 3 is fixedly installed on the workbench 1 and a target 10 is arranged on the guide rail 3; Mounting bracket 4: The mounting bracket 4 is slidably installed on the frame 2, and a mounting plate 5 is slidably installed on the mounting bracket 4; Coarse-tuning component 6: The coarse-tuning component 6 is arranged on the mounting bracket 4, and it includes a connecting rod 61 and a first universal ball 62 fixedly installed in the middle of the connecting rod 61; Mounting base 7: The mounting base 7 is arranged on one side of the mounting plate 5, and a clamping assembly 8 for clamping and fixing the laser is arranged on the mounting base 7; Fine-tuning assembly 9: The fine-tuning assembly 9 is arranged on the mounting plate 5 and is used to adjust the pitching and yaw angles of the laser.

[0023] In this embodiment, limiting grooves 912 are formed on both sides of the frame 2, limiting blocks are fixedly installed on both sides of the mounting frame 4 and are used in cooperation with the limiting grooves 912. The limiting blocks are slidably attached in the limiting grooves 912 on the same side to ensure the stability of the mounting frame 4 when sliding up and down on the frame 2. One side of the mounting frame 4 close to the mounting plate 5 has a trapezoidal portion, and a trapezoidal groove 12 for cooperating with the trapezoidal portion is formed on the mounting plate 5 to ensure the stability of the mounting plate 5 when sliding on the mounting frame 4.

[0024] Among them, as Figure 2 、 Figure 3 、 Figure 5 and Figure 6 shown, the coarse-tuning assembly 6 further includes two first electric push rods 63. The two first electric push rods 63 are vertically distributed and are both hinged to the frame 2. One end of the connecting rod 61 is fixedly installed with a connecting ball 64, and the other end is fixedly installed with an adjusting plate 65. A first ball socket 66 for cooperating with the first universal ball 62 is fixedly installed on the frame 2. The tops of the two first electric push rods 63 are both hinged with sliders 67. A chute 68 for cooperating with the sliders 67 is formed on the adjusting plate 65. The sliders 67 are slidably attached in the chutes 68 on the same side. A hollow ring sleeve 69 is fixedly installed inside the mounting plate 5. The connecting ball 64 is slidably attached inside the ring sleeve 69. One of the two first electric push rods 63 is horizontally arranged and the other is vertically arranged.

[0025] In this embodiment, a guide rod 610 is fixedly installed in the chute 68, and the slider 67 is slidably attached to the outer surface of the guide rod 610 on the same side, which can ensure the stability of the slider 67 when moving in the chute 68.

[0026] Specifically, the telescopic movement of the first electric push rod 63 drives the slider 67 on the same side to move in the chute 68. The movement of the slider 67 in the chute 68 will drive the adjustment plate 65 and the connecting rod 61 to deflect under the cooperation of the first universal ball 62 and the first ball sleeve 66. The deflection of the connecting rod 61 drives the connecting ball 64 to move in the ring sleeve 69, and drives the mounting bracket 4 or the mounting plate 5 to move through the ring sleeve 69, that is, the horizontal and vertical positions of the mounting seat 7 and the laser in the mounting seat 7 can be adjusted. Specifically, by the telescopic movement of the vertically arranged first electric push rod 63 and under the cooperation of the first universal ball 62 and the first ball head, the mounting bracket 4 is driven to slide on the frame 2, that is, the vertical height of the mounting seat 7 can be adjusted, so that the position where the laser beam irradiates on the target 10 is near the vertical direction of the center of the target 10. By the telescopic movement of the horizontally arranged first electric push rod 63, the mounting plate 5 can be driven to slide on the mounting bracket 4 to adjust the horizontal position of the mounting seat 7, so that the position where the laser beam irradiates on the target 10 is near the horizontal direction of the center of the target 10; thus, by the simultaneous and mutual cooperation of the two first electric push rods 63, the mounting seat 7 can be adjusted to any position in the horizontal and vertical directions at the same time, so that the position where the laser beam irradiates on the target is near the center of the target 10, completing the rough adjustment of the optical axis of the laser. The operation is simple and convenient to use, without the need for the operator to perform multiple repeated adjustments and measurements, improving the debugging efficiency.

[0027] Among them, as Figure 3 , Figure 4 , Figure 5 , Figure 6 and Figure 7 shown, the fine adjustment assembly 9 includes two threaded sleeves 91 rotatably mounted on the left and right sides of the mounting plate 5. Fine adjustment screws 92 are threadedly mounted in both threaded sleeves 91. One end of the fine adjustment screw 92 close to the mounting seat 7 is fixedly mounted with an elastic rubber cap 93. A universal ball head 94 is fixedly mounted on the elastic rubber cap 93. The universal ball head 94 is universally hinged to the mounting seat 7 through a ball cap 95 fixedly mounted on the mounting seat 7. A worm gear 96 is fixedly mounted on the outer surface of the threaded sleeve 91. A worm 97 meshing with the worm gear 96 is rotatably mounted on the mounting plate 5, and one end of the worm 97 is fixedly connected to the output end of a micro motor 98 provided on the mounting plate 5. A support rod 99 is fixedly mounted on the upper part of the mounting plate 5. One end of the support rod 99 is fixedly mounted with a second universal ball 910. A second ball sleeve 911 cooperating with the second universal ball 910 is fixedly mounted on the mounting seat 7. The support rod 99 is located on the perpendicular bisector of the line connecting the two fine adjustment screws 92.

[0028] Specifically, the micro-motor 98 drives the worm 97 to rotate. The rotation of the worm 97 drives the worm wheel 96 and the threaded sleeve 91 to rotate accordingly. The rotation of the threaded sleeve 91 drives the fine adjustment screw 92 and the elastic rubber cap 93 to move, and with the cooperation of the universal ball head 94 and the ball cap 95, it drives the mounting base 7 and the laser fixed in the mounting base 7 to deflect, that is, the pitch and deflection angles of the laser beam can be adjusted. Specifically, when the two micro-motors 98 rotate forward simultaneously, the two elastic rubber caps 93 extend simultaneously, causing relative movement between the universal ball head 94 and the ball cap 95 on the same side. With the cooperation of the second universal ball 910 and the second ball socket 911, under the action of the universal ball head 94 and the ball cap 95, the mounting base 7 and the laser can be lifted upward; when the two micro-motors 98 rotate backward simultaneously, the two elastic rubber caps 93 contract simultaneously, which can drive the mounting base 7 to pitch downward; when the left micro-motor 98 rotates backward, driving the left elastic rubber cap 93 to contract, and the right micro-motor 98 rotates forward, driving the right elastic rubber cap 93 to extend, the mounting base 7 can be driven to deflect to the left; when the left micro-motor 98 rotates forward and the right micro-motor 98 rotates backward, the mounting base 7 and the laser can be driven to deflect to the right. Thus, through the combined use of the two micro-motors 98, the pitch angle and yaw angle of the mounting base 7 and the laser can be accurately adjusted, achieving precise debugging of the optical axis of the laser. The operation is simple and convenient to use. Compared with the traditional method of adjusting the pitch and deflection angles of the optical axis by repeatedly turning the adjustment screws, it has the characteristics of simple operation, convenient use, good stability, and high adjustment efficiency.

[0029] Among them, as Figure 1 、 Figure 8 and Figure 9 shown, the clamping assembly 8 includes a second electric push rod 81 fixedly installed in the mounting base 7. The output end of the second electric push rod 81 is fixedly installed with a wedge-shaped frame 82. The two sides of the wedge-shaped frame 82 have wedge-shaped parts 821, and the two wedge-shaped parts 821 on both sides are symmetrically inclined. Moving blocks 83 are slidably installed on both sides of the mounting base 7. First clamping plates 84 are fixedly installed on the opposite surfaces of the two moving blocks 83 and on the wedge-shaped frame 82. A placement plate 85 is fixedly installed on the mounting base 7. Clamping air bags 86 are fixedly installed on the first clamping plates 84. Wedge-shaped grooves 87 for cooperating with the wedge-shaped parts 821 are formed on both moving blocks 83, and the moving blocks 83 are slidably connected to the wedge-shaped parts 821 on the same side.

[0030] Specifically, place the laser to be debugged on the placement plate 85, and then the second electric push rod 81 pushes the wedge-shaped frame 82 and the wedge part 821 downward. The downward movement of the wedge part 821 drives the moving blocks 83 on both sides to approach each other. The movement of the moving blocks 83 drives the first clamping plates 84 and the clamping air bags 86 thereon to move accordingly, so that the two first clamping plates 84 approach each other to clamp and fix the laser. While the wedge-shaped frame 82 moves downward, it will drive the first clamping plates 84 and the clamping air bags 86 thereon to move accordingly, and cooperate with the placement plate 85 and the first clamping plates 84 on the two moving blocks 83 to clamp and fix the laser. Thus, only by pushing the wedge-shaped frame 82 downward by the second electric push rod 81, the three first clamping plates 84 and the clamping air bags 86 thereon can be driven, and cooperate with the placement plate 85 to quickly clamp and fix the laser, ensuring the stability of the laser during debugging. The structure is simple, easy to use, convenient for quickly clamping the laser, improving the efficiency of laser debugging, and convenient for clamping and fixing lasers of different sizes, with a wide range of applications and strong practicability.

[0031] Among them, as Figure 9 shown, the clamping air bag 86 is composed of a clamping part 861 and side wall air bags 862 connected to both ends of the clamping part 861. The side wall air bags 862 are concave circular arcs, and the thickness of the side wall air bags 862 gradually decreases towards the clamping part 861. Multiple layers of retractable folds 863 are also provided on the side wall air bags 862, and the retractable folds 863 expand after being pressurized to fit the curved surface of the laser and generate additional friction.

[0032] Specifically, when the first clamping plate 84 and the clamping air bag 86 clamp and fix the laser, the gas in the clamping part 861 is pressed into the side wall air bags 862 due to the pressure on the clamping part 861. The pressure in the side wall air bags 862 increases. Since the thickness of the side wall air bags 862 gradually decreases towards the clamping part 861, the multiple layers of retractable folds 863 on the side wall air bags 862 can be fully expanded, increasing the contact area between the side wall air bags 862 and the laser, facilitating adaptation to different curved surfaces of the laser, and at the same time increasing the friction between the side wall air bags 862 and the laser, improving the stability when clamping and fixing the laser.

[0033] Among them, as Figure 8 shown, an arc-shaped support pad 88 is provided on the placement plate 85, which can protect the laser and facilitate preventing damage to the laser during clamping and fixing.

[0034] Among them, as Figure 4 and Figure 7 shown, a limit groove 912 is opened on the fine adjustment screw rod 92, and a limit rod for cooperating with the limit groove 912 is opened on the mounting plate 5. By the cooperation of the limit rod and the limit groove 912, the movement of the fine adjustment screw rod 92 can be guided and limited to prevent the fine adjustment screw rod 92 from rotating during movement.

[0035] A method for adjusting the optical axis of a laser, which is applied to a device for adjusting the optical axis of a laser in the above technical solution, includes the following steps: S1: Place the laser on the placement plate 85, drive the second electric push rod 81 to clamp and fix the laser, and then turn on the power supply of the laser to make it emit a laser beam; S2: Set a target 10 at a position on the light-emitting path of the laser. A cross center line and scale lines are drawn on the target 10; S3: By controlling the coordinated use of the two first electric push rods 63, adjust the vertical height and horizontal position of the mounting base 7 so that the position where the laser beam irradiates on the target is near the center of the target 10, and complete the rough adjustment of the laser beam; S4: Drive the two micro motors 98 to drive the fine adjustment screws 92 to rotate respectively. Through the mutual cooperation of the two micro motors 98, make the laser spot gradually move towards the center of the target 10. During the adjustment process, accurately control the adjustment amount of the pitch angle and yaw angle through the scale lines until the laser spot is completely located at the center of the target 10, and complete the precise adjustment of the optical axis of the laser.

[0036] During operation, place the laser to be adjusted on the placement plate 85, and then the second electric push rod 81 pushes the wedge-shaped frame 82 and the wedge-shaped part 821 to move downward. The downward movement of the wedge-shaped part 821 drives the moving blocks 83 on both sides to approach each other, so that the two first clamping plates 84 approach each other to clamp and fix the laser. While the wedge-shaped frame 82 moves downward, it will drive the first clamping plate 84 and the clamping airbag 86 thereon to move along, and cooperate with the placement plate 85 and the first clamping plates 84 on the two moving blocks 83 to quickly clamp and fix the laser. Then turn on the power supply of the laser to make it emit a laser beam; Place the target 10 at the position of the guide rail 3, and then drive the mounting frame 4 to slide on the frame 2 through the telescopic movement of the vertically arranged first electric push rod 63 and the cooperation of the first universal ball 62 and the first ball head, that is, the vertical height of the laser can be adjusted so that the position where the laser beam irradiates on the target 10 is near the vertical direction of the center of the target 10. By the telescopic movement of the horizontally arranged first electric push rod 63, the mounting plate 5 can be driven to slide on the mounting frame 4 to adjust the horizontal position of the mounting base 7 and the laser, so that the position where the laser beam irradiates on the target 10 is near the horizontal direction of the center of the target 10, and complete the rough adjustment of the optical axis of the laser; Then, start the micro-motor 98. The micro-motor 98 drives the worm 97 to rotate. The rotation of the worm 97 drives the worm gear 96 and the threaded sleeve 91 to rotate accordingly. The rotation of the threaded sleeve 91 drives the elastic rubber cap 93 to move, and with the cooperation of the universal ball head 94 and the ball cap 95, drives the mounting seat 7 and the laser to deflect. That is, the pitch and deflection angles of the laser beam can be adjusted. Specifically, when the two micro-motors 98 rotate forward simultaneously, they can drive the mounting seat 7 and the laser to pitch upward; when the two micro-motors 98 rotate backward simultaneously, they can drive the mounting seat 7 to pitch downward; when the left micro-motor 98 rotates backward and the right micro-motor 98 rotates forward, they can drive the mounting seat 7 to deflect to the left; when the left micro-motor 98 rotates forward and the right micro-motor 98 rotates backward, they can drive the mounting seat 7 and the laser to deflect to the right. Thus, through the combined use of the two micro-motors 98, the pitch angle and yaw angle of the mounting seat 7 and the laser can be accurately adjusted, achieving the precise debugging of the optical axis of the laser.

[0037] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention.
