Description

Technical Field

[0001] The present invention relates to the technical field related to laser debugging, and in particular to a laser optical axis debugging device and a debugging method. Background Art

[0002] A laser is a device that uses the principle of stimulated radiation to produce high-intensity, highly directional, highly monochromatic and highly coherent light beams. Its core function is to convert energy into laser light of a specific wavelength. It is widely used in communications, medical treatment, industrial processing and other fields.

[0003] In the application of laser technology, accurate debugging of the laser optical axis is very important. The deviation of the optical axis will cause the direction and position of the laser output to not meet the requirements, affecting the accuracy and effect of laser processing, measurement and other applications. Most of the existing laser optical axis debugging devices adjust the vertical and horizontal positions of the laser through separate adjustment mechanisms. The structure is relatively complex and the debugging process is cumbersome. When adjusting the deflection and pitch angles of the optical axis, the optical axis adjustment rod is mostly used to turn three adjustment screws to adjust the pitch and deflection angles of the optical axis respectively. The adjustment efficiency is low and the use is relatively inconvenient.

[0041] The preferred embodiments of the present invention are described below 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.

[0042] Example: Figures 1 to 9 As shown, the present invention provides a laser optical axis debugging device, comprising a workbench 1, a frame 2 and a control panel 11 arranged on the workbench 1, and further comprising:

[0043] Guide rail 3: The guide rail 3 is fixedly mounted on the workbench 1 and a target 10 is provided on the guide rail 3;

[0045] Coarse adjustment assembly 6: The coarse adjustment assembly 6 is arranged on the mounting frame 4, and includes a connecting rod 61 and a first universal ball 62 fixedly installed in the middle of the connecting rod 61;

[0046] Mounting seat 7: The mounting seat 7 is provided on one side of the mounting plate 5 and is provided with a clamping assembly 8 for clamping and fixing the laser;

[0047] Fine-tuning component 9: The fine-tuning component 9 is arranged on the mounting plate 5 and is used to adjust the pitch and yaw angles of the laser.

[0048] In this embodiment, limiting grooves 912 are provided on both sides of the frame 2, and limiting blocks used in conjunction with the limiting grooves 912 are fixedly installed on both sides of the mounting frame 4. The limiting blocks slide 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. The mounting frame 4 has a trapezoidal portion on the side close to the mounting plate 5, and the mounting plate 5 is provided with a trapezoidal groove 12 used in conjunction with the trapezoidal portion to ensure the stability of the mounting plate 5 when sliding on the mounting frame 4.

[0049] Among them, Figure 2 、 Figure 3 、 Figure 5 and Figure 6 As shown, the coarse adjustment assembly 6 also includes two first electric push rods 63, which are vertically distributed and hinged to the frame 2. A connecting ball 64 is fixedly installed at one end of the connecting rod 61, and an adjusting plate 65 is fixedly installed at the other end. A first ball sleeve 66 used in conjunction with the first universal ball 62 is fixedly installed on the frame 2. The top ends of the two first electric push rods 63 are hinged with sliders 67, and a sliding groove 68 used in conjunction with the slider 67 is opened on the adjusting plate 65. The slider 67 slides in the sliding groove 68 on the same side. An internal hollow ring sleeve 69 is fixedly installed in the mounting plate 5, and the connecting ball 64 slides in the ring sleeve 69. One of the two first electric push rods 63 is arranged horizontally and the other is arranged vertically.

[0050] In this embodiment, a guide rod 610 is fixedly installed in the slide groove 68, and the slider 67 slides on 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 slide groove 68.

[0051] In detail, the extension and retraction of the first electric push rod 63 drives the slider 67 on the same side to move in the slide groove 68. The movement of the slider 67 in the slide groove 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 frame 4 or the mounting plate 5 to move through the ring sleeve 69, so that the horizontal and vertical positions of the mounting seat 7 and the laser in the mounting seat 7 can be adjusted. Specifically, by extending and retracting the vertically arranged first electric push rod 63 and driving the mounting frame 4 to slide on the frame 2 under the cooperation of the first universal ball 62 and the first ball head, the vertical height of the mounting seat 7 can be adjusted so that the laser beam The position of the target 10 irradiated is near the vertical direction of the center of the target 10. The expansion and contraction of the horizontally arranged first electric push rod 63 can drive the mounting plate 5 to slide on the mounting frame 4, and adjust the horizontal position of the mounting seat 7 so that the position of the laser beam irradiated on the target 10 is near the horizontal direction of the center of the target 10; thus, the two first electric push rods 63 can be used in conjunction with each other at the same time to adjust the mounting seat 7 to any position in the horizontal and vertical directions at the same time, so that the position of the laser beam irradiated on the target is near the center of the target 10, completing the coarse adjustment of the laser optical axis. The operation is simple and easy to use. There is no need for workers to make repeated adjustments and measurements, thereby improving the debugging efficiency.

[0052] Among them, such as Figure 3 、 Figure 4 、 Figure 5 、 Figure 6 and Figure 7 As shown, the fine-tuning assembly 9 includes two threaded sleeves 91 rotatably mounted on the left and right sides of the mounting plate 5, and fine-tuning screws 92 are threadedly mounted in the two threaded sleeves 91. An elastic rubber cap 93 is fixedly mounted on one end of the fine-tuning screw 92 close to the mounting seat 7, and 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, and a worm 97 meshing with the worm gear 96 is rotatably mounted on the mounting plate 5, and one end of the worm gear 97 is fixedly connected to the output end of the 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, and a second universal ball 910 is fixedly mounted on one end of the support rod 99. A second ball sleeve 911 used in conjunction with the second universal ball 910 is fixedly mounted on the mounting seat 7. The support rod 99 is located on the mid-perpendicular line of the line connecting the two fine-tuning screws 92.

[0053] In detail, the micro motor 98 drives the worm 97 to rotate, and 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-tuning 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, drives the mounting seat 7 and the laser fixed in the mounting seat 7 to deflect, that is, the pitch and deflection angles of the laser beam can be adjusted. Specifically, the two micro motors 98 rotate forward at the same time to drive the two elastic rubber caps 93 to extend at the same time, so that the universal ball head 94 and the ball cap 95 on the same side move relative to each other, and with the cooperation of the second universal ball 910 and the second ball sleeve 911, the mounting seat 7 and the laser can be driven to pitch up under the action of the universal ball head 94 and the ball cap 95; the two micro motors 98 rotate backward at the same time to drive the two elastic rubber caps 93 to extend at the same time, so that the universal ball head 94 and the ball cap 95 on the same side move relative to each other, and with the cooperation of the second universal ball 910 and the second ball sleeve 911, the mounting seat 7 and the laser can be driven to pitch up under the action of the universal ball head 94 and the ball cap 95; The rubber cap 93 contracts at the same time, which can drive the mounting base 7 to pitch downward; the micro motor 98 on the left reverses to drive the elastic rubber cap 93 on the left to contract, and the micro motor 98 on the right rotates forward to drive the elastic rubber cap 93 on the right to extend, which can drive the mounting base 7 to deflect to the left; the micro motor 98 on the left rotates forward, and the micro motor 98 on the right reverses, which can drive the mounting base 7 and the laser to deflect to the right; thus, the pitch angle and yaw angle of the mounting base 7 and the laser can be precisely adjusted by the coordinated use of the two micro motors 98, thereby achieving precise debugging of the laser optical axis. The operation is simple and easy to use. Compared with the traditional method of adjusting the pitch and yaw angles of the optical axis by repeatedly turning the adjustment screws, the method has the characteristics of simple operation, easy use, good stability and high adjustment efficiency.

[0054] Among them, such as Figure 1 、 Figure 8 and Figure 9 As shown, the clamping assembly 8 includes a second electric push rod 81 fixedly mounted in the mounting seat 7, a wedge frame 82 is fixedly mounted on the output end of the second electric push rod 81, wedge-shaped portions 821 are provided on both sides of the wedge frame 82, and the wedge-shaped portions 821 on both sides are symmetrically inclined. Moving blocks 83 are slidably mounted on both sides of the mounting seat 7, first clamping plates 84 are fixedly mounted on the opposite surfaces of the two moving blocks 83 and the wedge frames 82, a placing plate 85 is fixedly mounted on the mounting seat 7, a clamping airbag 86 is fixedly mounted on the first clamping plate 84, wedge grooves 87 for cooperating with the wedge portions 821 are provided on the two moving blocks 83, and the moving blocks 83 are slidably connected to the wedge portions 821 on the same side.

[0055] Specifically, the laser to be debugged is placed on the placement plate 85, and then the second electric push rod 81 pushes the wedge frame 82 and the wedge portion 821 to move downward. The wedge portion 821 moves downward to drive the moving blocks 83 on both sides to move closer to each other. The movement of the moving block 83 drives the first clamping plate 84 and the clamping airbag 86 thereon to follow the movement, so that the two first clamping plates 84 are close to each other to clamp and fix the laser. When the wedge 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 clamp and fix the laser, so that only the second electric push rod 81 pushes the wedge frame 82 to move downward to drive the three first clamping plates 84 and the clamping airbags 86 thereon 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, and convenient for quick clamping of the laser, which improves the efficiency of laser debugging and is convenient for clamping and fixing lasers of different sizes. It has a wide range of applications and strong practicality.

[0056] Among them, Figure 9 As shown, the clamping airbag 86 consists of a clamping portion 861 and a side wall airbag 862 connected to both ends of the clamping portion 861. The side wall airbag 862 is concave arc-shaped and the thickness of the side wall airbag 862 gradually decreases toward the side away from the clamping portion 861. The side wall airbag 862 is also provided with multiple layers of retractable folds 863. After pressurization, the retractable folds 863 expand to fit the curved surface of the laser and generate additional friction.

[0057] Specifically, when the first clamping plate 84 and the clamping airbag 86 clamp and fix the laser, the clamping portion 861 is pressurized so that the gas in the clamping portion 861 flows into the side wall airbag 862, and the pressure in the side wall airbag 862 increases. Since the thickness of the side wall airbag 862 gradually decreases toward the side away from the clamping portion 861, the multi-layer retractable pleats 863 on the side wall airbag 862 can be fully expanded, increasing the contact area between the side wall airbag 862 and the laser, making it easier to adapt to the different curved surfaces of the laser, and at the same time increasing the friction between the side wall airbag 862 and the laser, thereby improving the stability of the laser when clamped and fixed.

[0058] Among them, Figure 8 As shown, an arc-shaped support pad 88 is provided on the placement plate 85 to protect the laser and prevent the laser from being damaged when being clamped and fixed.

[0059] Among them, Figure 4 and Figure 7As shown, a limit slot 912 is provided on the fine-tuning screw 92, and a limit rod used in conjunction with the limit slot 912 is provided on the mounting plate 5. By cooperating with the limit rod and the limit slot 912, the movement of the fine-tuning screw 92 can be guided and limited to prevent the fine-tuning screw 92 from rotating during movement.

[0060] A laser optical axis debugging method, applied to a laser optical axis debugging device in the above technical solution, comprises the following steps:

[0061] 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 laser power supply to make it emit a laser beam;

[0062] S2: A target 10 is set at a position on the light output path of the laser, and a cross center line and scale lines are drawn on the target 10;

[0063] S3: By controlling the coordinated use of the two first electric push rods 63, the vertical height and horizontal position of the mounting base 7 are adjusted so that the position where the laser beam is irradiated on the target is near the center of the target 10, thereby completing the coarse adjustment of the laser beam;

[0064] S4: Drive the two micro motors 98 to rotate the fine-tuning screw 92 respectively. Through the cooperation of the two micro motors 98, the laser spot gradually moves toward the center of the target 10. During the adjustment process, the pitch angle and yaw angle are accurately controlled by the scale lines until the laser spot is completely located in the center of the target 10, completing the precise adjustment of the laser optical axis.

[0065] During operation, the laser to be debugged is placed on the placement plate 85, and then the second electric push rod 81 pushes the wedge frame 82 and the wedge portion 821 to move downward. The downward movement of the wedge portion 821 drives the moving blocks 83 on both sides to move closer to each other, so that the two first clamping plates 84 move closer to each other to clamp and fix the laser. When the wedge frame 82 moves downward, it drives the first clamping plate 84 and the clamping airbag 86 thereon to move along, and cooperates 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, the laser power is turned on to make it emit a laser beam.

[0066] The target 10 is placed on the guide rail 3. The mounting frame 4 is driven to slide on the frame 2 by the extension and retraction of the vertically arranged first electric push rod 63 and the cooperation of the first universal ball 62 and the first ball head. This allows the vertical height of the laser to be adjusted so that the position where the laser beam is irradiated on the target 10 is near the vertical direction of the center of the target 10. The horizontally arranged first electric push rod 63 is extended and retracted to drive the mounting plate 5 to slide on the mounting frame 4. The horizontal positions of the mounting seat 7 and the laser are adjusted so that the position where the laser beam is irradiated on the target 10 is near the horizontal direction of the center of the target 10. This completes the coarse adjustment of the laser optical axis.

[0067] Then, the micromotor 98 is started, and the micromotor 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 elastic rubber cap 93 to move, and with the cooperation of the universal ball head 94 and the ball cap 95, the mounting seat 7 and the laser are driven to deflect, that is, the pitch and yaw angles of the laser beam can be adjusted. Specifically, the two micromotors 98 rotate forward at the same time, which can drive the mounting seat 7 and the laser to pitch upward; the two micromotors 98 rotate backward at the same time, which can drive the mounting seat 7 to pitch downward; the left micromotor 98 rotates backward and the right micromotor 98 rotates forward, which can drive the mounting seat 7 to deflect to the left; the left micromotor 98 rotates forward and the right micromotor 98 rotates backward, which can drive the mounting seat 7 and the laser to deflect to the right; thus, the pitch angle and yaw angle of the mounting seat 7 and the laser can be accurately adjusted by the coordinated use of the two micromotors 98, thereby achieving precise debugging of the laser optical axis.

[0068] Finally, it should be noted that the above descriptions are merely preferred embodiments of the present invention and are not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art will be able to modify the technical solutions described in the aforementioned embodiments or substitute equivalents for some of the technical features.
