Description

Technical Field

[0001] The present invention belongs to the technical field of laser welding, and more particularly, relates to a laser welding device capable of collecting smoke and spatter. Background Art

[0002] Laser welding equipment is a mechanical device that uses a laser beam to perform precision welding of metals and non-metallic materials. The welding principle is that the laser welding head emits a high-energy-density laser beam to locally heat the weld area, melting the weld material to form a molten pool. The metal in the molten pool then cools completely to achieve the connection. Currently, when the high-energy-density laser beam is irradiated on the weld material, the weld material evaporates and melts, producing harmful gaseous fumes. However, traditional laser welding equipment lacks a fume collection system, causing operators to inhale the diffused harmful fumes, seriously damaging their respiratory health. Furthermore, the boiling of the liquid metal in the molten pool increases the internal pressure, pushing the surrounding liquid metal particles out of the weld area, forming a small amount of hot spatter. This hot spatter not only burns the operator supporting the workpiece, but also adheres to the laser welding equipment's platform after cooling, making it difficult to clean and collect.

[0034] In the embodiment of the present invention, the smoking tube 29 is a cylindrical structure that passes through from top to bottom. The laser emitting end at the bottom of the laser welding head 17 is inserted into the inner side of the smoking tube 29. The bottom end of the smoking tube 29 is a flared structure. The flared structure of the smoking tube 29 increases the suction range of welding smoke. A connecting hole is provided on the outer side of the smoking tube 29 near the flared position, and an air intake pipe 8 is sealed and bonded at the connecting hole.

An observation window 6 is bonded to the inner side of the through groove of the flap 7. The observation window 6 is made of high-temperature resistant transparent glass. When the flap 7 is flipped and closed at the front end of the stop shell 23, it is convenient for the operator to observe the welding condition of the workpiece inside the stop shell 23. A magnet sheet 31 is bonded to the rear side of the flap 7. The flap 7 is connected to the concave shell The baffle shell 23 of the body structure is attracted to each other through the magnet sheet 31, so that the flap 7 and the baffle shell 23 surround and block the spatters from the welding part of the workpiece. A flat plate is provided on the inner side of the concave shell structure of the baffle shell 23, and two sets of through grooves are provided on the upper side of the flat plate. A splint 28 is slidably connected in the through groove of the flat plate of the baffle shell 23. Through holes are provided on the left and right sides of the concave shell structure of the baffle shell 23. A bidirectional threaded rod 32 is rotatably connected in the through hole of the baffle shell 23, and a knob 24 is installed on the left end of the bidirectional threaded rod 32.

[0038] In the embodiment of the present invention, there are two groups of splints 28, and the splints 28 are symmetrically distributed on the left and right sides. Each group of splints 28 has an I-shaped structure. The center part of the I-shaped structure of the splint 28 is embedded in the through groove on the side surface of the inner plate of the baffle shell 23. A threaded through hole is provided on the I-shaped structure of the splint 28. The threaded through hole of the left splint 28 is engaged with the positive thread end of the two-way threaded rod 32, and the threaded through hole of the right splint 28 is engaged with the reverse thread end of the two-way threaded rod 32. During the rotation of the two-way threaded rod 32, the two groups of splints 28 are driven to move left and right along the through groove of the inner plate of the baffle shell 23, so that the splints 28 support and clamp the welding workpiece left and right, thereby avoiding the displacement of the weld position of the workpiece during laser welding.

[0039] The specific usage and function of this embodiment are as follows: When the laser welding of the workpieces is carried out, the two groups of workpieces to be welded are first placed on the flat plate of the stop shell 23, and then the knob 24 is manually rotated. The knob 24 drives the bidirectional threaded rod 32 to rotate. Since the positive threaded end and the reverse threaded end on the outer side of the bidirectional threaded rod 32 are respectively engaged with the threaded through holes of the two groups of clamps 28, the bidirectional threaded rod 32 drives the clamps 28 to clamp and fix the two groups of workpieces to be welded in the left and right directions, and then the flap 7 is flipped upward until the magnet piece 31 bonded to the rear side of the flap 7 is attracted to the magnet piece 31 at the front end of the stop shell 23. The flap 7 and the stop shell 23 surround and shield the welding workpieces, and then the smoking pipe 29 is put on the outside of the laser welding machine head 17, and then the pushing drum 30 is manually rotated. Due to the pushing The inner side of the rotating drum 30 is threadedly engaged with the threaded structure on the outer side of the smoking tube 29, and the pushing rotating drum 30 is pressed downward on the outer side of the smoking tube 29. The pushing rotating drum 30 pushes the inclined structure of the four groups of clamps 27, so that the clamps 27 move synchronously and centripetally along the grooves and through slots of the smoking tube 29 until the rubber gaskets bonded to the four groups of clamps 27 are tightly fitted to the outer side of the laser welding head 17, completing the clamping and fixing of the smoking tube 29 at the bottom end of the laser welding head 17. Then the control machine 3 controls the horizontal displacement motor 10 through the line to drive the horizontal threaded adjustment rod 15 to rotate. The horizontal threaded adjustment rod 15 drives the laser welding head 17 to move left or right through the slider 16 engaged with the outer side, and the control machine 3 controls the longitudinal displacement motor through the line. 12 drives the driving gear 21 to rotate. Since the driving gear 21 and the rack plate 22 are meshed with each other, the driving gear 21 rolls on the tooth surface of the rack plate 22. At this time, the gantry 11 drives the laser welding head 17 to move forward or backward along the support rod 13 until the laser welding head 17 is opposite to the starting welding position of the workpiece. Then, the control machine 3 controls the laser welding head 17 and the fan motor 904 to start synchronously through the line. The laser welding head 17 emits a laser beam to weld the workpiece. The fan motor 904 drives the fan disk 908 at the top of the transmission rod 907 to rotate. The fan disk 908 stirs the air in the exhaust pipe 902 to form an air negative pressure inside the exhaust pipe 902. At this time, the flared part of the smoking pipe 29 will press the laser welding head 17 The smoke generated by welding is sucked into the intake pipe 8, and the intake pipe 8 sends the smoke into the chimney 901. The smoke is adsorbed and filtered by the HEPA air filter cotton 905, and the filtered air is discharged into the external environment through the through holes of the air permeable plate 906 and the through grooves of the exhaust pipe 902. The spatters generated by the laser welding head 17 during the laser welding process fall into the clean water of the water tank 4 through the concave structure that passes through the baffle shell 23. The spatters cool and solidify during the sinking process in the clean water, and the solidified spatters sink to the bottom of the water tank 4. If the spatters need to be collected and cleaned uniformly, manually pull the hand lever 5 to pull the water tank 4 out from between the two sets of vertical plates of the placement table 1, and then pour out the solidified spatters in the water tank 4 with the clean water.

[0040] All of the above components are installed, connected, or configured using common mechanical methods, such as welding, threaded connections, and screw connections. The specific structures, models, and coefficients of all components are proprietary technologies, and any method that can achieve a beneficial effect may be implemented. The controller 3, fan motor 904, lateral displacement motor 10, longitudinal displacement motor 12, laser welding head 17, and vertical displacement motor 18 used above are all commonly available components.
