Description

Technical Field

[0001] The invention relates to the technical field of pulse laser welding, in particular to a pulse laser welding device for high-reflectivity metals. Background Art

[0002] The characteristic of high reflectivity metal is that when light is irradiated to the metal surface, the metal can absorb more light energy and quickly re-radiate the absorbed energy in the form of light to form reflection. Therefore, there are problems such as high reflectivity, high welding energy, and poor welding quality in the laser welding process. The Chinese patent application with application number 202120539472.X discloses "a blowing protection device for pulsed laser welding of thin plate stainless steel, including a collimating focusing head. The blowing protection device for pulsed laser welding of thin plate stainless steel, through the outer side of the column, movably sleeves the slider, and fixes the movable plate between the two sliders so that the movable plate can move up and down, and movably connects the rotating shaft on the right side of the movable plate, and fixes the connecting plate on the right side of the rotating shaft so that the connecting plate can rotate, and fixes a fixed rod on the right side of the connecting plate, and rotatably connects the rotating plate on the outer side of the fixed rod, and fixes the side blowing pipe at the bottom of the rotating plate so that the side blowing pipe can rotate, so that the position of the side blowing pipe can be arbitrarily adjusted, so as to realize the possibility of adjusting the side blowing pipe to the optimal blowing protection position relative to the welding workpiece, thereby achieving the effect of good surface gloss and no oxidation after welding". This technical solution only solves the problem that spatter and other fumes generated during the laser welding process are easy to contaminate the focusing reflector. However, when using pulsed laser to weld metals with high reflectivity, the metals with high reflectivity can reflect most of the incident laser energy, resulting in less energy absorbed by the welding area. Therefore, in order to ensure successful welding, it is often necessary to pre-process the welding area manually, such as manually grinding the welding area so that the welding point of the high reflectivity metal is roughened to reduce laser reflection. However, in production, manual processing cannot guarantee the processing effect and is slow, resulting in low welding efficiency of high reflectivity metals. Summary of the invention

[0018] Working principle: When the present invention is used, the high-reflectivity metal to be welded is placed on the welding platform 2, and the welding platform 2 is controlled by the control box 1 to drive the high-reflectivity metal to move forward and backward, and the movable frame 4 on the frame 3 is controlled by the control box 1 to move, so as to drive the pulse laser emitting device 5 to move, so that the pulse laser emitting device 5 is aligned with the welding position and then descends, and then the welding platform 2 is controlled to drive the welding starting point of the high-reflectivity metal to move to the front end of the cleaning wheel 804; When the movable frame 4 descends, the mounting plate 601 is driven to descend, so that the pulse laser emitting device 5, the texturing mechanism 6, the reciprocating mechanism 7, the cleaning mechanism 8 and the driving mechanism 9 are all lowered, and then the welding part of the high-reflectivity metal first contacts the cleaning wheel 804, and the cleaning wheel 804 is lifted up by the high-reflectivity metal, and the synchronous plate 801 is driven to rise through the connecting frame 803 and the connecting rod 802, and the lifting frame 607 at the front end is driven to rise through the synchronous plate 801; After the cleaning wheel 804 contacts the high-reflectivity metal, the motor 902 is started, and the output rod 903 is driven to rotate by the motor 902, and the transmission sleeve 906 is driven to rotate by the first transmission belt 908, and the vertical shaft 904 is driven to rotate by the transmission sleeve 906, so that the first bevel gear 909 rotates following the vertical shaft 904, and the second bevel gear 910 is driven to rotate by the first bevel gear 909. At this time, the first short rod 911 rotates following the second bevel gear 910 at the left end, and the cleaning wheel 804 is driven to rotate by the second transmission belt 913.

At this time, the reciprocating frame 708 is driven to perform reciprocating lifting motion through the reciprocating rod 707, and the driving rack 709 is driven to perform reciprocating lifting motion through the reciprocating frame 708. When the driving rack 709 performs reciprocating lifting motion, the driving gear 70 2 drives the gear shaft 701 to reciprocate, so that the reciprocating gear 703 follows the gear shaft 701 to reciprocate, and at this time, the two reciprocating blocks 604 are driven to reciprocate through the two sets of transmission racks 704. When the reciprocating blocks 604 reciprocate, the grinding blocks 611 are driven to reciprocate through the lifting frame 607 and the lifting rod 608, so that the grinding blocks 611 can reciprocate quickly after contacting the high-reflectivity metal, thereby grinding the surface of the high-reflectivity metal, making the surface of the high-reflectivity metal rough, thereby reducing the reflectivity of the high-reflectivity metal welding point, and improving the effect of pulse laser welding.
