The main functions of laser cleaning, cutting and welding include:

[0003] Cleaning effect: Laser cleaning can efficiently and environmentally remove dirt, rust, particles or coatings on the surface of the workpiece, providing a clean processing surface for subsequent cutting and welding. Laser cleaning is non-contact and will not cause mechanical damage to the workpiece, and no new pollutants will be generated during the cleaning process.

[0004] Cutting function: Laser cutting has the advantages of fast speed, high precision, small heat-affected zone, etc., and can achieve accurate cutting of various materials. Laser cutting is suitable for the processing of metal and non-metal materials, especially for the cutting of complex shapes and special-shaped parts.

[0005] Welding function: Laser welding has the characteristics of high energy density, fast welding speed and low welding heat input. It is an efficient, precise and low-deformation welding method. Laser welding can realize the welding of various materials, including thin plates, thick plates and welding between different materials.

When the positioning hole vertically positions the lower end of the laser head, the sixth driving motor is turned on by control. When the sixth driving motor is turned on, it will drive the transmission screw to rotate, and the outer curved threads at both ends of the transmission screw automatically face opposite directions, so that when the transmission screw rotates, it will drive the slider to move linearly inward synchronously. When the slider moves linearly inward synchronously, it will drive the clamping block to clamp and fix the upper end of the laser head inward synchronously, thereby facilitating the clamping and fixing of the laser head;

[0019] S2: When the laser head is clamped and fixed, the first drive motor is turned on by control. When the first drive motor is turned on, it drives the first synchronous wheel to rotate.

When the front and rear moving frames move linearly forward and backward, the clamped and fixed laser head is synchronously driven to move linearly forward and backward to adjust the cutting position. At the same time, the second driving motor is turned on by control. When the second driving motor is turned on, the front and rear swinging frames are sequentially driven to swing forward and backward. When the front and rear swinging frames swing forward and backward, the clamped and fixed laser head is synchronously driven to swing forward and backward to adjust the cutting position.

[0026] 2. The present invention also controls to start the third driving motor at the same time. When the third driving motor is turned on, it will drive the left and right moving frame to move linearly left and right along the outer curved surface of the second limit slide bar in turn. When the left and right moving frame moves linearly left and right, it will synchronously drive the clamped and fixed laser head to move linearly left and right to adjust the cutting position; at the same time, by controlling to start the fourth driving motor, when the fourth driving motor is turned on, it will drive the vertical moving block to move linearly up and down along the outer curved surface of the third limit slide bar in turn. When the vertical moving block moves linearly up and down, it will synchronously drive the clamped and fixed laser head to move linearly up and down to adjust the cutting position; at the same time, by controlling to start the fifth driving motor, when the fifth driving motor is turned on, it will drive the L-shaped adjustment frame to swing left and right in turn. When the L-shaped adjustment frame swings left and right, it will synchronously drive the clamped and fixed laser head to swing left and right to adjust the cutting position, thereby facilitating the front and back, left and right, and up and down linear movement adjustment of the laser head, while the front and back swing and left and right swing to adjust the cutting position, so that the laser head can meet the cutting requirements of different positions.

9. A method for using the laser head cleaning and welding optical module adjustment device according to any one of claims 1 to 8, characterized in that: The steps are as follows: S1: By placing the lower end of the laser head on the inner wall of the positioning hole 34, when the lower end of the laser head is placed on the inner wall of the positioning hole 34, the positioning hole 34 is used to vertically position the lower end of the laser head. When the positioning hole 34 vertically positions the lower end of the laser head, the sixth drive motor 30 is turned on by control. When the sixth drive motor 30 is turned on, it will drive the transmission screw 31 to rotate, and the outer curved threads at both ends of the transmission screw 31 automatically face opposite directions, so that when the transmission screw 31 rotates, it will drive the slider 32 to move linearly inward synchronously. When the slider 32 moves linearly inward synchronously, it will drive the clamping block 33 to clamp and fix the upper end of the laser head inward synchronously, thereby facilitating the clamping and fixing of the laser head. S2: When the laser head is clamped and fixed, the first drive motor 4 is turned on by control. When the first drive motor 4 is turned on, it will drive the first synchronous wheel 5 to rotate. When the first synchronous wheel 5 rotates, it will drive the first transmission screw 7 to rotate through the synchronous belt and the second synchronous wheel 6. When the first transmission screw 7 rotates, it will drive the front and rear moving frame 8 to move straight back and forth along the outer curved surface of the first limit slide bar 9 through the screw nut. When the front and rear moving frame 8 moves straight back and forth, it will synchronously drive the clamped laser head to move straight back and forth to adjust the cutting position; S3: The second driving motor 10 is turned on by control. When the second driving motor 10 is turned on, the first transmission gear 11 is driven to rotate. When the first transmission gear 11 rotates, the front and rear swing frames 14 are driven to swing back and forth through the first transmission gear ring 12 and the swing shaft column 13. When the front and rear swing frames 14 swing back and forth, the clamped laser head is synchronously driven to swing back and forth to adjust the cutting position. S4: The third driving motor 15 is turned on by control. When the third driving motor 15 is turned on, the third synchronous wheel 16 is driven to rotate. When the third synchronous wheel 16 rotates, the second transmission screw 18 is driven to rotate by synchronously driving and transmitting with the fourth synchronous wheel 17. When the second transmission screw 18 rotates, the left and right moving frame 19 is driven to move straightly left and right along the outer curved surface of the second limit slide bar 20 due to the transmission of the screw nut. When the left and right moving frame 19 moves straightly left and right, it will synchronously drive the clamped and fixed laser head to move straightly left and right to adjust the cutting position. S5: The fourth drive motor 21 is turned on by control. When the fourth drive motor 21 is turned on, the third transmission screw 22 is driven to rotate. When the third transmission screw 22 rotates, the vertical moving block 23 is driven to move up and down along the outer curved surface of the third limit slide bar 24 through the screw nut. When the vertical moving block 23 moves up and down, it will synchronously drive the clamped laser head to move up and down to adjust the cutting position. S6: The fifth drive motor 25 is turned on by control. When the fifth drive motor 25 is turned on, it will drive the second transmission gear 26 to rotate. When the second transmission gear 26 rotates, it will drive the L-shaped adjustment frame 28 to swing left and right through the second transmission gear ring 27. When the L-shaped adjustment frame 28 swings left and right, it will synchronously drive the clamped laser head to swing left and right to adjust the cutting position.
