Description

Technical Field

[0001] The invention belongs to the technical field of laser welding equipment, in particular to a laser wire feeding welding device. Background Art

[0002] Laser welding is an efficient and precise welding method that uses a high-energy-density laser beam as a heat source. Laser welding with a wire feeding mechanism is a commonly used welding method. It uses the wire feeding mechanism to level the welding wire and continuously transport the welding wire to the laser head, and then uses the laser radiation energy to melt the welding wire and stack the wire on the workpiece surface to achieve welding.

[0003] The prior art uses a wire feeding welding device by manually taking the handle of the laser welding gun, then passing the welding wire through the wire feeding gun, adjusting the end of the wire feeding gun to be located on one side of the laser head, then feeding the welding wire from the end of the wire feeding gun to ensure that the laser beam emitted by the laser head can contact the welding wire, then aiming the laser head at the weld, and the laser beam emitted by the laser head melts the welding wire. The melted welding wire contacts the weld, and then the weld can be welded. When welding an arc surface or changing the welding direction, it is necessary to adjust the wire feeding gun to be consistent with the movement direction so that the laser beam can always contact the welding wire.

DETAILED DESCRIPTION

[0029] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below in conjunction with specific implementation methods.

[0030] Embodiment 1, as Figure 1-Figure 3 As shown, a laser wire feeding welding device described in an embodiment of the present invention includes a handheld laser welding gun 1, a laser head 11 is installed at the lower end of the handheld laser welding gun 1, the handheld laser welding gun 1 is connected to a laser 111 through a wiring harness, a wire feeding gun 14 is provided on one side of the handheld laser welding gun 1, the wire feeding gun 14 is connected to a wire feeder 141 through a pipeline, and the wire feeder 141 is arranged at the upper end of the laser 111, and also includes an inertial sensor 12 installed on one side of the lower end of the handheld laser welding gun 1, a motor 121 is installed on the side of the handheld laser welding gun 1 away from the inertial sensor 12, a first ring 13 is rotatably connected to the upper end of the laser head 11, the motor 121 can drive the first ring 13 to rotate through a gear set, and one side of the first ring 13 is connected to the wire feeding gun 14.

[0031] Specifically, the existing laser welding device includes a welding gun and a wire feeding gun, and the welding gun is provided with a laser head, a laser, and a handle; when using the handheld laser wire feeding welding device for welding, first manually take the handle of the handheld laser welding gun 1, then pass the welding wire through the wire feeding gun 14, adjust the end of the wire feeding gun 14 to be located on one side of the laser head 11, and then feed the welding wire from the end of the wire feeding gun 14 to ensure that the laser beam emitted by the laser head 11 can contact the welding wire, then aim the laser head 11 at the weld, and then start the laser 111, and the laser head 11 emits a laser beam through the transmission of the wire beam, and the laser beam contacts the welding wire to melt the welding wire, and the melted welding wire contacts the weld, and then the weld can be welded. When welding an arc surface or changing the welding direction, it is necessary to always keep the movement direction of the wire feeding gun 14 consistent with that of the laser head 11, so it is necessary to constantly manually adjust the direction of the wire feeding gun 14. Since the temperature of the laser beam is high, the temperature of the laser head 11 will be high. Manual adjustment may cause burns, and the adjustment process is relatively cumbersome. When using the present device, a handle is provided on one side of the handheld laser welding gun 1. The handle is manually taken, and after adjusting the distance between the wire feeding gun 14 and the laser head 11, the laser head 11 is aimed at the weld, and then the laser 111 is started to make the laser head 11 emit a laser beam to melt the welding wire. The melted welding wire contacts the weld and welds the weld. When the laser head 11 is driven to change the welding direction, the inertial sensor 12 can monitor and sense the movement state of the laser head 11 in real time. When it is detected that the transport direction of the laser head 11 has changed, the laser head 11 is started by controlling the motor 121, and the motor 121 drives the first ring 13 to rotate through the gear set. When the first ring 13 rotates, it can drive the wire feeding gun 14 to rotate outside the laser head 11, so that when the welding angle of the laser head 11 is changed, the swing angle of the wire feeding gun 14 can be automatically controlled, and the position of the wire feeding gun 14 can be adjusted without stopping the machine for manual adjustment.

[0032] like Figure 3 As shown, the gear set includes a gear 122 fixedly connected to the output end of the motor 121, the gear 122 is meshed with a gear ring 123, the gear ring 123 is rotatably arranged on the outside of the laser head 11, the gear ring 123 is fixedly connected to the first ring 13, a first connecting rod 131 is fixedly connected to one side of the first ring 13, one end of the first connecting rod 131 is rotatably connected to the second connecting rod 132, and one end of the second connecting rod 132 is fixedly connected to the wire feeding gun 14.

[0033] Specifically, when the inertial sensor 12 detects that the welding direction of the laser head 11 has changed, the motor 121 is controlled to start, driving the gear 122 to rotate, the gear 122 drives the ring gear 123 to rotate, and the ring gear 123 drives the wire feeding gun 14 to rotate around the laser head 11 through the first ring 13. The position of the wire feeding gun 14 can be monitored and adjusted in real time to always be consistent with the movement direction of the laser head 11 without manual adjustment.

[0034] like Figure 1As shown, a controller 124 is fixedly connected to the upper end of the wire feeder 141 , and the controller 124 is connected to the inertial sensor 12 via a wiring harness.

[0035] Specifically, the inertial sensor 12 can sense the motion state of the laser head 11, including the direction and magnitude of speed, the direction and magnitude of acceleration, the inclination angle, etc. When the inertial sensor 12 detects that the welding direction of the laser head 11 has changed, the inertial sensor 12 sends the motion state of the laser head 11 to the controller 124. The controller 124 outputs appropriate control signals such as wire feeding parameters and laser parameters through parameter matching and sends them to the wire feeder 141, the motor 121 and the laser 111, thereby controlling the change of the position of the wire feeding gun 14 relative to the laser head 11, the wire feeding speed and the laser power.

[0036] like Figure 4 As shown, a wire outlet 142 is provided at one side of the lower end of the wire feeder 141, and a plurality of sixth connecting rods 143 are rotatably connected around the wire outlet 142 through torsion springs, and arc-shaped rotating wheels 144 are rotatably provided at one end of the sixth connecting rods 143.

[0037] Specifically, a rolled welding wire is installed inside the wire feeder 141, and the welding wire is pulled out from the wire outlet 142 and passed through the wire feeding gun 14. The wire feeding gun 14 limits the end of the welding wire, and the rolled welding wire is driven to rotate so that the welding wire can be output from the wire outlet 142 to the outside, and welding is performed by continuously feeding the welding wire. During the welding process, the wire feeding gun 14 needs to rotate according to the welding direction of the laser head 11. Several sixth connecting rods 143 provided at the wire outlet 142 clamp the welding wire through the arc-shaped rotating wheel 144 to prevent the welding wire from being pulled when the wire feeding gun 14 rotates, causing the welding wire to bend.

[0038] like Figure 5 As shown, a support assembly is fixedly connected to the upper end of the handheld laser welding gun 1, and the support assembly includes a first T-shaped rod 2 fixedly connected to the upper end of the handheld laser welding gun 1, and cylindrical bars 22 are respectively slidably penetrated through the three ends of the first T-shaped rod 2, and cylinders 21 are respectively fixedly connected to the lower ends of the three ends of the first T-shaped rod 2, and the cylindrical bars 22 can slide in the cylinders 21.

[0039] Specifically, during welding, it is necessary to manually pick up the handheld laser welding gun 1 all the time. When the handheld laser welding gun 1 is moved for welding, the distance between the laser head 11 and the weld cannot be always maintained. By arranging cylindrical bars 22 around the laser head 11 for support, and driving the cylindrical bars 22 to slide in the cylinder 21, the distance between the laser head 11 and the weld can be controlled. At the same time, when the laser head 11 moves, the laser head 11 is supported so that the distance between the laser head 11 and the weld is always maintained consistent.

[0040] like Figure 5 As shown, balls 221 are rotatably arranged at the lower ends of the cylindrical bars 22.

[0041] Specifically, when the cylindrical bar 22 supports the laser head 11, the laser head 11 moves, driving the cylindrical bar 22 to move on the upper end of the plate. When the cylindrical bar 22 moves, the ball 221 provided at the bottom end rotates with the plate to prevent scratches.

[0042] like Figure 5 As shown, the upper ends of the cylindrical bars 22 are respectively fixedly connected with second T-shaped rods 23 , and the middle part of the second T-shaped rod 23 is threadedly connected with a screw rod 24 , and the screw rod 24 can rotate on the upper end of the first T-shaped rod 2 .

[0043] Specifically, by driving the screw rod 24 to rotate, the second T-shaped rod 23 can be driven to move upward, and the second T-shaped rod 23 can simultaneously drive the cylindrical bar 22 to move upward, so that the laser head 11 can be moved downward, and the distance between the laser head 11 and the weld can be adjusted according to the size and depth of different welds.

[0044] like Figure 6-Figure 7 As shown, a protective component is provided on one side of the laser head 11, and the protective component includes a circular plate 3 fixed to the lower end of the middle part of the handheld laser welding gun 1, a second circular ring 31 is rotatably provided on the outer side of the circular plate 3, a first rectangular bar 33 is rotatably provided on one side of the second circular ring 31, a conical cylinder 331 is fixed to one side of the lower end of the first rectangular bar 33, and an opening is provided on the conical cylinder 331 near the laser head 11, and inclined plates 332 are respectively fixed to both sides of the opening.

[0045] Specifically, when the laser head 11 completes welding, the temperature of the laser head 11 will increase due to the high temperature of the laser beam generated. When the handheld laser welding gun 1 is moved, the laser head 11 is always exposed to the outside, and it may cause burns if it is accidentally touched. When using the present invention, after welding is completed, the upper end of the first rectangular bar 33 is driven to rotate away from the circular plate 3, so that the lower end of the first rectangular bar 33 moves toward the side close to the laser head 11. The first rectangular bar 33 drives the conical tube 331 to approach the laser head 11. The conical tube 331 is a spring sheet and can be deformed. The inclined plate 332 contacts the side of the laser head 11 to expand the opening position of the conical tube 331 until the laser head 11 enters the middle of the conical tube 331. The conical tube 331 protects the laser head 11 to prevent accidental touching of the laser head 11 and causing burns.

[0046] like Figure 6 As shown, the second circular ring 31 is rotatably connected to a J-shaped rod 32 at one side away from the first rectangular bar 33 , and the lower end of the J-shaped rod 32 is rotatably connected to a third circular ring 321 , and the third circular ring 321 can slide outside the wire feeding gun 14 .

[0047] Specifically, after welding is completed, due to the high temperature of the laser head 11, it is necessary to adjust the wire feeding gun 14 away from the laser head 11 to prevent the welding wire at the end of the wire feeding gun 14 from melting and dripping to cause pollution. By driving the upper end of the J-shaped rod 32 to rotate away from the circular plate 3, the lower end of the J-shaped rod 32 moves toward the side close to the laser head 11, driving the third ring 321 to move toward the side close to the laser head 11. At the same time, the third ring 321 slides on the outside of the wire feeding gun 14, and then the wire feeding gun 14 rotates with the first connecting rod 131 through the second connecting rod 132, driving the lower end of the wire feeding gun 14 away from the laser head 11.

[0048] Embodiment 2, as Figure 7 As shown, compared with Example 1, another implementation of the present invention is: the upper end of the first rectangular bar 33 is rotatably connected to the second rectangular bar 34, and the two ends of one side of the second rectangular bar 34 are respectively rotatably connected to the third connecting rod 341, the upper end of the J-shaped rod 32 is rotatably connected to the third rectangular bar 35, and the two ends of one side of the third rectangular bar 35 are respectively rotatably connected to the fourth connecting rod 351, and the two sides of the upper end of the circular plate 3 are respectively fixed with rectangular blocks 361, and one side of the rectangular block 361 is respectively rotatably connected to the fifth connecting rod 36 through damping, and the two third connecting rods 341 are respectively rotatably connected to the fifth connecting rod 36 at one end away from the second rectangular bar 34, and the fifth connecting rod 36 is respectively rotatably connected to the fourth connecting rod 351 at one end away from the third connecting rod 341, and the middle of the fifth connecting rod 36 is respectively fixed with a rotating block 362.

[0049] Specifically, by driving the rotating block 362 to rotate, the fifth connecting rod 36 is driven to rotate, and the fifth connecting rod 36 drives the third connecting rod 341 and the fourth connecting rod 351 at both ends to move in opposite directions respectively, and the third connecting rod 341 drives the second rectangular bar 34 to move away from the circular plate 3, and the second rectangular bar 34 drives the upper end of the first rectangular bar 33 to rotate away from the circular plate 3, so that the lower end of the first rectangular bar 33 moves toward the side close to the laser head 11, and the first rectangular bar 33 drives the conical tube 331 to wrap the laser head 11, and at the same time, the fourth connecting rod 351 drives the third rectangular bar 35 Move away from the side of the circular plate 3, the third rectangular bar 35 drives the upper end of the J-shaped rod 32 to rotate toward the side away from the circular plate 3, so that the lower end of the J-shaped rod 32 moves toward the side close to the laser head 11, and drives the third circular ring 321 to move toward the side close to the laser head 11. At the same time, the third circular ring 321 slides on the outside of the wire feeding gun 14, and then the wire feeding gun 14 rotates with the first connecting rod 131 through the second connecting rod 132, driving the lower end of the wire feeding gun 14 away from the laser head 11. When the lower end of the wire feeding gun 14 is away from the laser head 11, the conical cylinder 331 can be moved to the outside of the laser head 11 for protection.

[0050] Working principle: a handle is provided on one side of the handheld laser welding gun 1. The handle is manually taken when in use. A cylindrical bar 22 is provided around the laser head 11 for support. By driving the screw rod 24 to rotate, the second T-shaped rod 23 can be driven to move upward. The second T-shaped rod 23 simultaneously drives the cylindrical bar 22 to move upward, so that the laser head 11 can be moved downward. The distance between the laser head 11 and the weld can be adjusted according to the size and depth of different welds. When the laser head 11 is moved to weld the weld, the cylindrical bar 22 is driven to move on the upper end of the plate when the laser head 11 moves, so that the distance between the laser head 11 and the weld is always consistent.

[0051] During welding, when the laser head 11 is driven to change the welding direction, the inertial sensor 12 can monitor and sense the movement state of the laser head 11 in real time. When it is detected that the transport direction of the laser head 11 has changed, the laser head 11 starts by controlling the motor 121 to drive the gear 122 to rotate, and the gear 122 drives the gear ring 123 to rotate. The gear ring 123 drives the wire feeding gun 14 to rotate around the laser head 11 through the first ring 13. The position of the wire feeding gun 14 can be monitored and adjusted in real time to always be consistent with the movement direction of the laser head 11 without manual adjustment. The sensor 12 can sense the motion state of the laser head 11, including the direction and magnitude of the speed, the direction and magnitude of the acceleration, the inclination angle, etc. When the inertial sensor 12 detects that the welding direction of the laser head 11 changes, the inertial sensor 12 sends the motion state of the laser head 11 to the controller 124. The controller 124 outputs appropriate control signals such as wire feeding parameters and laser parameters to the wire feeder 141, the motor 121 and the laser 111 through parameter matching, thereby controlling the change of the position of the wire feeding gun 14 relative to the laser head 11, the wire feeding speed and the laser power;

[0052] When the laser head 11 completes welding, the temperature of the laser head 11 will increase due to the high temperature of the laser beam generated. When the handheld laser welding gun 1 is moved, the laser head 11 is always exposed to the outside, and it may cause burns if it is accidentally touched. When using the present invention, the fifth connecting rod 36 is driven to rotate by driving the rotating block 362 to rotate. The fifth connecting rod 36 drives the third connecting rod 341 and the fourth connecting rod 351 at both ends to move in opposite directions respectively. The third connecting rod 341 drives the second rectangular bar 34 to move away from the circular plate 3. The second rectangular bar 34 drives the upper end of the first rectangular bar 33 to rotate away from the circular plate 3, so that the lower end of the first rectangular bar 33 moves toward the side close to the laser head 11. The strip 33 drives the conical tube 331 to wrap the laser head 11, and at the same time, the fourth connecting rod 351 drives the third rectangular strip 35 to move away from the circular plate 3, and the third rectangular strip 35 drives the upper end of the J-shaped rod 32 to rotate away from the circular plate 3, so that the lower end of the J-shaped rod 32 moves toward the side close to the laser head 11, and drives the third circular ring 321 to move toward the side close to the laser head 11. At the same time, the third circular ring 321 slides on the outside of the wire feeding gun 14, and then the wire feeding gun 14 rotates with the first connecting rod 131 through the second connecting rod 132, driving the lower end of the wire feeding gun 14 away from the laser head 11. When the lower end of the wire feeding gun 14 is away from the laser head 11, the conical tube 331 can be moved to the outside of the laser head 11 for protection.
