[0037] The overall idea of ​​the technical solution of the embodiment of the present invention is as follows:

[0038] A reflector is set in front of the focusing lens of the laser, and the reflector is connected to the support seat through a displacement angle adjustment device; the displacement angle adjustment device includes a slide, a swing table and a clamping block, the slide is used to change the distance between the reflector and the focusing lens, the swing table is used to change the angle of the reflector, and the clamping block is used to fix the reflector; when the slide moves, it does not interfere with the swing table; when the swing table rotates, it does not interfere with the slide; the distance and angle of the reflector can be adjusted independently, that is, the distance between the reflector and the focusing lens and the angle of the reflector can be decoupled. During the debugging process, the data of the power meter, spectrum analyzer, and spot detector are monitored in sequence as an important reference in the assembly process, which is used to evaluate and adjust the assembly accuracy and determine the best fixed position and the best fixed angle of the reflector.

[0039] In order to better understand the above technical solution, the above technical solution will be described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0040] See also Figures 1 to 5 , Embodiment 1 of the present invention.

[0041] A laser assembly automation system for decoupling spacing and angle by a reflection method, comprising:

[0042] Laser light source 1, focusing lens 2, reflecting mirror 3, beam splitter 4, power meter 5, spectrum analyzer 6, light spot detector 7, light splitter 8, supporting seat 9 and displacement angle adjustment device 10;

[0043] The laser light source 1, focusing lens 2, beam splitter prism 4, light spot detector 7, power meter 5, spectrum analyzer 6, and light splitter 8 are all fixedly arranged on the support seat 9, and the reflector 3 is connected to the support seat 9 through the displacement angle adjustment device 10;

[0044] The mirror surface of the reflector 3 is coated with a partial reflective film;

[0045] The light emitted by the laser light source 1 passes through the focusing lens 2 and the reflector 3 in sequence, and then enters the beam splitter 4 to be divided into a first split light 41 and a second split light 42. The first split light 41 enters the light spot detector 7, and the second split light 42 enters the light splitter 8 to be divided into a third split light 43 and a fourth split light 44. The third split light 43 enters the power meter 5, and the fourth split light 44 enters the spectrum analyzer 6.

[0046] The displacement angle adjustment device 10 includes a slide 101, a swing table 102 and a clamping block 103. The slide 101 is slidably connected to the support seat 9, the swing table 102 is rotationally connected to the slide 101, the clamping block 103 is fixedly connected to the swing table 102, and the reflector 3 is placed on the clamping block 103.

[0047] The present invention independently adjusts the spacing and angle of the reflector 3 through the displacement angle adjustment device 10. When the slide seat 101 adjusts the spacing between the reflector 3 and the focusing lens 2, the angle of the reflector 3 remains unchanged. When the swing table 102 adjusts the angle of the reflector 3, the spacing between the reflector 3 and the focusing lens 2 remains unchanged, thereby improving the assembly accuracy of the laser. During the assembly adjustment process, the performance of the laser is monitored in real time and used as a feedback reference in combination with the light power of the power meter 5, the spectral characteristics of the spectrum analyzer 6, and the spot information of the spot detector 7, so as to determine the spacing and angle parameters of the reflector 3 and improve the consistency and stability of product assembly. The assembly process of the laser reduces human intervention, improves assembly speed and efficiency, and reduces production costs.

[0048] The displacement angle adjustment device 10 further includes a damping rail 104 and a damping shaft 105, wherein the damping rail 104 is installed between the slide 101 and the support platform, and the damping shaft 105 is installed between the swing table 102 and the slide 101. The beneficial effects of this technical solution are: in manual operation mode, the staff can push the slide 101 or rotate the swing table 102 only when a certain force is applied; when the staff does not apply a force, the slide 101 remains stationary due to the damping function of the damping rail 104, and the swing table 102 remains stationary due to the damping function of the damping shaft 105; thus, the position deviation of the slide 101 and the angle deviation of the swing table 102 caused by external shaking are avoided.

[0049] It also includes an assembly table 20, a ball screw drive device 30 and a reduction gear drive device 40, the support seat 9 is fixedly arranged on the upper surface of the assembly table 20, the ball screw drive device 30 is installed on the assembly table 20, the nut portion of the ball screw drive device 30 is detachably connected with the slide seat 101, the reduction gear drive device 40 is installed on the nut portion of the ball screw drive device 30, and the output shaft of the reduction gear drive device 40 is detachably connected with the swing table 102. The beneficial effect of this technical solution is that before debugging the optimal position of the slide seat 101, the ball screw drive device 30 is installed and connected with the slide seat 101, and before debugging the optimal angle of the swing table 102, the reduction gear drive device 40 is installed and connected with the swing table 102; after completing the debugging, the connection between the ball screw drive device 30 and the slide seat 101 is disassembled, and the connection between the reduction gear drive device 40 and the swing table 102 is disassembled. Finally, the connection between the assembly table 20 and the support seat 9 is disassembled.

[0051] The MCU 50 is electrically connected to the power meter 5 , the first servo motor 60 , and the second servo motor 70 ;

[0052] The power meter 5 sends the detected light power signal to the MCU 50. The MCU 50 first sends a first adjustment signal to the first servo motor 60 to change the position of the slide 101 within a set displacement range. At the same time, the MCU 50 records the received light power value. When the light power value reaches the maximum, the MCU 50 stops sending the first adjustment signal to the first servo motor 60.

[0053] The MCU50 then sends a second adjustment signal to the second servo motor 70 to change the angle of the swing table 102. At the same time, the MCU50 records the received light power value. When the light power value reaches the maximum, the MCU50 stops sending the second adjustment signal to the second servo motor 70. The beneficial effect of this technical solution is that the first servo motor 60 and the second servo motor 70 provide an automatic operation mode to automatically adjust the position of the slide 101 and the angle of the swing table 102 respectively; thereby automatically adjusting the position and angle of the reflector 3. When the position or angle of the reflector 3 changes, the light power value detected by the power meter 5 also changes. The MCU50 records the light power value, thereby quickly finding the position of the slide 101 and the angle of the swing table 102 corresponding to the maximum light power.

[0054] The MCU 50 is also electrically connected to the spectrum analyzer 6 and the light spot detector 7. The beneficial effect of this technical solution is that the MCU 50 also receives the spectrum characteristics of the spectrum analyzer 6 and the light spot information of the light spot detector 7, and sequentially monitors the data of the power meter 5, the spectrum analyzer 6, and the light spot detector 7 as an important reference in the assembly process, for evaluating and adjusting the assembly accuracy, and determining the best fixing position and the best fixing angle of the reflector 3.

[0055] The focusing lens 2 is connected to the support seat 9 via another displacement angle adjustment device 10.

[0056] The reflectivity of the partially reflective film is 10%.

[0057] It also includes an optical glue spraying device (not shown), which is installed on the assembly table 20. The beneficial effect of this technical solution is that after determining the optimal fixing position and the optimal fixing angle of the reflector 3, the optical glue spraying device is used to spray optical glue on the slide 101 and the swing table 102, thereby fixing the reflector 3. The optical glue spraying device includes an optical glue storage tank, a metering pump and a spray gun. During the gluing process, the optical glue spraying device reduces the variable factors of manual glue application by accurately controlling the flow and distribution of the optical glue, thereby ensuring the stability and reliability of the laser structure.
