[0002] A laser welding machine generates laser light through a laser module, reflects, refracts and focuses the laser light through a series of optical lenses, focuses the laser light into an optical fiber, transmits the laser light through the optical fiber, and acts on a workpiece through a laser welding head. Since laser light can be stably output, the relative position and angle of the optical lenses need to be adjusted during assembly to ensure the accurate transmission path of the laser light.
[0003] However, the volume of the optical lenses is small, and during the current manual debugging process, the lenses cannot be easily adjusted, the lenses are prone to displacement during fixing, and the relative position and angle of the lenses are slightly changed, which brings great inconvenience to the optical debugging personnel of the laser module. In addition, when the lenses are fixed with glue, the amount of glue applied is uneven due to manual operation, the lenses are offset due to the stress caused by the uneven glue after being pasted and solidified, the operator needs to hold the curing lamp for irradiation during the manual UV glue curing process, the operator can only hold the curing lamp to align the lenses to be irradiated during the whole process, the position of the lenses irradiated by the hand-held curing lamp is different for different operators, the curing time and the state after curing are not uniform, and the consistency of the laser module cannot be ensured.

Step S3: By rotating the adjusters (2-5) on the XY manual displacement stage (2-2), the angle measurement manual displacement stage (2-3), and the rotary manual displacement stage (2-4), the position and installation angle of the lens are adjusted so that the lens accurately reflects the laser and forms a laser spot. Step S4: Monitor the size and position of the laser spot using a CCD imager (7) to determine whether the position and angle of the lens are adjusted correctly. If so, the adjustment of the lens is completed in step S5. Then the main control system (6) sends an external control signal to control the Z-axis (11) of the worktable (10) to move and drive the lens adjustment fixture to move up a predetermined first distance. In step S6, the main control system (6) gives an external control signal to control the angle motor (5-3) to move. The angle motor (5-3) rotates the shaft based on the set angle to move the syringe light shield (5-5) away. Step S7, the main control system (6) gives an external control signal to control the reversing valve B to change the airflow direction of compressed air into the cylinder (4-1), so that the cylinder (4-1) is displaced and drives the glue injector (4-3) to move to the workpiece surface (9), which is the position to be fixed of the lens. Step S8: Set the dispensing volume and set it to external control mode through the dispensing controller (4-5) to control the glue injector (4-3) to inject a fixed amount of glue onto the surface of the workpiece; In step S9, the main control system (6) gives an external control signal to control the reversing valve B to change the airflow direction of compressed air into the cylinder (4-1), so that the cylinder (4-1) is displaced and drives the glue injector (4-3) away from the workpiece surface (9). In step S10, the main control system (6) gives an external control signal to control the angle motor (5-3) to rotate the angle and return the syringe light shield (5-5) to its original position. In step S11, the main control system (6) gives an external control signal to control the Z-axis (11) of the worktable (10) to move and drive the lens adjustment fixture to move down a predetermined second distance so that the lens returns to the workpiece surface (9). Step S12: Monitor the size and position of the laser spot using a CCD imager (7) to determine whether the position and angle of the lens are adjusted correctly. Step S13, if yes, then according to the preset irradiation angle and irradiation duration, the main control system (6) gives an external control signal to control the UV curing lamp (5-1) to start, and the UV curing lamp (5-1) cures the lens, and the UV curing lamp (5-1) is automatically turned off after curing is completed. Step S14: Rotate the reversing valve A to change the airflow direction of compressed air into the parallel open-closed pneumatic gripper (3-1) so that it is in the open state, control the Z-axis (11) of the worktable (10) to move, and the Z-axis (11) of the worktable (10) drives the lens adjustment fixture to move upward away from the workpiece surface and the lens, thus completing the lens installation process.
