[0021] The present invention is further described below in conjunction with the accompanying drawings and specific embodiments so that those skilled in the art can better understand the present invention and implement it, but the embodiments are not intended to limit the present invention.

[0022] Reference Figures 1 to 3 As shown, a laser rolling welding device of the present invention includes: a laser emitting element 2; a support seat 1, wherein a first channel 15 is provided in the support seat 1, the laser emitting element 2 is connected to the support seat 1, and the output end of the laser emitting element 2 is located at the input end of the first channel 15; a mounting seat 5, wherein the mounting seat 5 is connected to the support seat 1, the mounting seat 5 is provided with a second channel 52 connected to the first channel 15, the mounting seat 5 is further provided with a receiving groove 53 and a third channel 51, the third channel 51 is used for airflow to pass through, the second channel 52 and the third channel 51 are both connected to the receiving groove 53; an optical rolling element 6, the optical rolling element 6 is clamped in the receiving groove 53, and the optical rolling element 6 can move in the receiving groove 53.

[0023] In a laser rolling welding device of the present embodiment, air flow is introduced into the third channel 51, so that the space between the optical roller 6 and the side wall of the receiving groove 53 is filled with gas, and the optical roller 6 is pressed down on the object to be welded by an external moving device, so that the optical roller 6 moves in the receiving groove 53. At this time, there is a gap between the optical roller 6 and the open end of the receiving groove 53, and air flow flows between the optical roller 6 and the side wall of the receiving groove 53. The flow of air flow allows the optical roller 6 to apply pressure to the welding position while avoiding friction between the optical roller 6 and the side wall of the receiving groove 53. The laser emitting element 2 emits a welding laser to the first channel 15, and the welding laser enters the second channel 52 along the first channel 15. The welding laser passes through the optical roller 6 after passing through the second channel 52 to reach the welding position, and the optical roller 6 rolls with the movement of the welding position. Through the movable cooperation between the optical roller 6 and the receiving groove 53, and the cooperation between the airflow in the third channel 51 and the optical roller 6, the optical roller 6 can avoid friction between the optical roller 6 and the side wall of the receiving groove 53 while applying pressure to the welding position. It can also avoid sliding friction between the optical roller 6 and the object to be welded during the movement of the laser rolling welding device, thereby avoiding wear or scratches on the surface of the object to be welded.

[0024] Reference Figure 1 As shown, the support seat 1 is in the shape of a plate as a whole, and a laser emitting component 2 is provided on the top of the support seat 1. The laser emitting component 2 is connected to an external controller, and the laser emitter can emit welding laser.

[0025] A first channel 15 is provided in the support seat 1 , the output end of the laser emitting element 2 is located at the input end of the first channel 15 , and the welding laser emitted by the laser emitting element 2 coincides with the center line of the first channel 15 .

[0026] The mounting base 5 is connected to the supporting base 1 , and is provided with a second channel 52 connected to the first channel 15 . A receiving groove 53 and a third channel 51 are also provided on one side of the mounting base 5 . The third channel 51 is used for airflow to pass through. Both the second channel 52 and the third channel 51 are connected to the receiving groove 53 .

[0027] Reference Figure 2As shown, the support seat 1 further includes a fourth channel 16, a first mounting block 11 and a first reflector 13. The fourth channel 16 is located between the first channel 15 and the second channel 52, and the two ends of the fourth channel 16 are respectively connected to the first channel 15 and the second channel 52. The first mounting block 11 is connected to the mounting seat 5, and the first reflector 13 is engaged with the first mounting block 11. The first reflector 13 is located at the connecting position between the first channel 15 and the fourth channel 16, and the first reflector 13 extends into the path of the welding laser. When the center lines of the second channel 52 and the first channel 15 are not collinear, the welding laser can be collinear with the center line of the second channel 52 through the adjustment of the first reflector 13 and the transition of the fourth channel 16, that is, the welding laser can be emitted along the center line of the second channel 52.

[0028] The support seat 1 also includes a fifth channel 17, a second mounting block 12, and a second reflector 14. The fifth channel 17 is located between the fourth channel 16 and the second channel 52. The two ends of the fifth channel 17 are connected to the fourth channel 16 and the second channel 52 respectively. The second mounting block 12 is connected to the mounting seat 5. The second reflector 14 is clamped with the second mounting block 12. The second reflector 14 is located at the connecting position between the fifth channel 17 and the fifth channel 17. The function of the second reflector 14 is the same as that of the first reflector 13, which will not be repeated. In this embodiment, the center line of the fifth channel 17 is colinear with the center line of the second channel 52, the center line of the first channel 15 is parallel to the center line of the fifth channel 17, and the center line of the fourth channel 16 is perpendicular to the center line of the first channel 15 and the center line of the fifth channel 17. Through the arrangement of the first reflector 13 and the second reflector 14, the emission angle of the welding laser can be accurately adjusted. Through the arrangement of the first mounting block 11 and the second mounting block 12, it is convenient to adjust the posture of the first reflector 13 and the second reflector 14, and then it is convenient to adjust the emission angle of the welding laser.

[0029] Reference Figure 3 As shown, the optical roller 6 is made of a material that can be passed through by welding lasers, and the optical roller 6 is clamped in the receiving groove 53, and the optical roller 6 can move in the receiving groove 53. Specifically, the opening end of the receiving groove 53 is smaller than the diameter of the optical roller 6, so as to prevent the optical roller 6 from being separated from the receiving groove 53 from the opening end of the receiving groove 53. The receiving groove 53 is in an arc shape that matches the shape of the optical roller 6 as a whole, and the diameter of the receiving groove 53 is slightly larger than the diameter of the optical roller 6. When the optical roller 6 is clamped at the port position of the receiving groove 53, there is a gap between the side wall of the optical roller 6 and the side wall of the receiving groove 53.

[0030] The center line of the second channel 52 coincides with the center line of the mounting seat 5. The third channel 51 is located near the side wall of the mounting seat 5. The mounting seat 5 is provided with an opening connected to the third channel 51. The third channel 51 is provided with a valve body 54 connected to the opening. The output end of the external air supply device can be connected to the valve body 54, so as to supply air to the third channel 51. The airflow in the third channel 51 can flow into the gap between the optical roller 6 and the side wall of the receiving groove 53. When the optical roller 6 moves toward the bottom of the receiving groove 53, the gap between the optical roller 6 and the side wall of the receiving groove 53 is reduced, and a gap appears between the optical roller 6 and the open end of the receiving groove 53. At this time, the receiving groove 53 is connected to the outside. The airflow in the third channel 51 can pass through the gap between the optical roller 6 and the receiving groove 53 and flow out from the open end of the receiving groove 53. At this time, the optical roller 6 can roll in the receiving groove 53, and the optical roller 6 will not rub against the side wall of the receiving groove 53. The airflow flowing through the optical roller 6 can also cool the optical roller 6. A plurality of third channels 51 can be provided, so that the airflow in the receiving groove 53 is more stable, and the flow rate of the airflow in the receiving groove 53 can be increased, that is, the pressure of the airflow on the optical roller 6 is increased. The diameter of the third channel 51 close to one end of the receiving groove 53 gradually decreases, that is, the output end of the third channel 51 is tapered, thereby increasing the flow rate of the airflow output from the third channel 51. The side wall of the open end of the receiving groove 53 can fit with the optical roller 6, thereby preventing the optical roller 6 from being scratched by the clamping of the open end of the receiving groove 53 and the optical roller 6.

[0031] The side wall of the fifth channel 17 is connected to a support frame 7, which is in a hollow tube shape, and the welding laser can pass along the center line of the support frame 7. A condenser 71 is provided at one end of the support frame 7 away from the second channel 52, and the condenser 71 is used to condense the welding laser, thereby reducing the diffusion of the welding laser after being reflected by the first reflector 13 and the second reflector 14. After passing through the condenser 71, the welding laser can continue to move along the center line of the fifth channel 17.

[0032] The connecting seat 4 is located between the supporting seat 1 and the mounting seat 5. A connecting block 41 is provided at the end of the connecting seat 4. The connecting block 41 extends into the supporting frame 7 and is connected to the supporting frame 7. The ends of the connecting block 41 are respectively connected to the supporting seat 1 and the mounting seat 5. The connecting block 41 is used to locate the position of the connecting seat 4 and can also improve the stability of the connection between the connecting seat 4 and the supporting seat 1. The connecting seat 4 is provided with a sixth channel 43. The two ends of the sixth channel 43 are respectively connected to the fifth channel 17 and the second channel 52. The center line of the sixth channel 43 is collinear with the center line of the second channel 52.

[0033] The connecting seat 4 also includes a seventh channel 42, which is located between the sixth channel 43 and the fifth channel 17, and the seventh channel 42 is located at the center position of the end of the connecting seat 4 away from the mounting seat 5. The diameter of the seventh channel 42 gradually decreases toward the sixth channel 43, that is, the seventh channel 42 is tapered as a whole, and the diameters of the sixth channel 43, the second channel 52 and the output end of the seventh channel 42 are equal, and the diameters of the fifth channel 17 and the output end of the seventh channel 42 are equal. The setting of the seventh channel 42 can avoid the safety risks caused by the deviation of the welding laser angle and the scrapping of the welded parts caused by the deviation of the welding position of the welded parts.

[0034] It also includes a driving member 3, which can be regarded as a linear cylinder. The driving member 3 is fixed to the outside, and the output end of the driving member 3 is connected to the support seat 1 through a connecting plate 31. The conveying path of the driving member 3 is parallel to the center line of the second channel 52. The driving member 3 can drive the support seat 1 to press down, thereby accurately adjusting the pressure between the optical roller 6 and the welded part and the moving distance of the optical roller 6.

[0035] When in use, the laser rolling welding device is connected to the output end of the external moving device, and the third channel 51 is passed with air flow. The space between the optical roller 6 and the side wall of the receiving groove 53 is filled with gas. The external moving device causes the optical roller 6 to press down on the object to be welded, and the driving member 3 drives the support seat 1 to move so as to accurately adjust the pressing position. At this time, the optical roller 6 moves in the receiving groove 53, and the gap between the optical roller 6 and the side wall of the receiving groove 53 is reduced, and a gap appears between the optical roller 6 and the open end of the receiving groove 53. The receiving groove 53 is connected to the outside, and the laser emitting member 2 emits a welding laser to the first channel 15. The welding laser is reflected by the first reflector 13 and the second reflector 14 and enters the seventh channel 42 through the fourth channel 16 and the fifth channel 17. The welding laser passes through the seventh channel 42, the sixth channel 43 and the second channel 52 in sequence, and then passes through the optical roller 6 after passing through the second channel 52 to reach the welding position, and the optical roller 6 rolls with the movement of the welding position.

[0036] A laser rolling welding device of the present invention, through the movable cooperation between the optical roller 6 and the receiving groove 53, and the cooperation between the airflow in the third channel 51 and the optical roller 6, can prevent the optical roller 6 from rubbing against the side wall of the receiving groove 53 while applying pressure to the welding position, and can also prevent the optical roller 6 from sliding and rubbing against the object to be welded during the movement of the laser rolling welding device, thereby avoiding wear or scratches on the surface of the object to be welded. The pressure between the optical roller 6 and the object to be welded and the moving distance of the optical roller 6 can be accurately adjusted by the driving member 3. The emission angle of the welding laser can be accurately adjusted by the arrangement of the first reflector 13 and the second reflector 14, and the posture of the first reflector 13 and the second reflector 14 can be adjusted by the arrangement of the first mounting block 11 and the second mounting block 12, thereby facilitating the adjustment of the emission angle of the welding laser.

[0037] Obviously, the above embodiments are merely examples for clear explanation and are not intended to limit the implementation methods. For those skilled in the art, other different forms of changes or modifications can be made based on the above description.
