Specific implementation manner

[0020] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention.

[0021] The present invention provides a technical solution: As Figures 1 to 6 shown, in this embodiment, a laser soldering device with an automatic wire cutting function includes a fixing frame 1. A wire pay-off motor 2 is fixedly installed at the top of the fixing frame 1. A wire reel 3 is fixedly installed at the output end of the wire pay-off motor 2. A tension pulley 4 is installed at a position below the wire reel 3 corresponding to the fixing frame 1. A mounting plate 5 is installed at a position on one side of the fixing frame 1 away from the wire reel 3. A moving plate 6 is slidably installed on one side of the mounting plate 5. The moving plate 6 can move left and right and up and down. A wire threading needle 7 is fixedly installed on one side of the moving plate 6. The wire passes through the wire threading needle 7. A wire pressing mechanism is fixedly installed at a position below the wire threading needle 7 on one side of the moving plate 6.

A centering gripper 9 is fixedly installed at the bottom end of the fixing frame 1 corresponding to the product positioning tooling 8. A laser welding gun 10 is fixedly installed on the fixing frame 1 corresponding to the centering gripper 9. A solder feeding module 11 is fixedly installed on the fixing frame 1 corresponding to the laser welding gun 10. A wire cutting module 12 is fixedly installed at the top end of the fixing frame 1 corresponding to the centering gripper 9.

[0022] As Figures 1 to 6 shown, a fixing rod 13 is rotatably installed in the middle of the tension pulley 4. One end of the fixing rod 13 away from the tension pulley 4 is rotatably installed on one side of the fixing frame 1 through a shaft pin. A tension spring 14 is fixedly installed between the fixing rod 13 and the fixing frame 1.

[0023] When the wire reel 3 is rotated by the wire pay-off motor 2 to release the wire, the tension spring 14 will continuously drive the tension pulley 4 to squeeze and receive the wire by pulling the fixing rod 13, so as to ensure the tension of the wire.

[0024] As shown Figures 1 to 6 As shown, the wire pressing mechanism includes a cylinder 15, a wire pressing column 16 and a fixing block 17. A cylinder 15 is fixedly installed on one side of the moving plate 6 corresponding to the position below the threading needle 7. The moving end of the cylinder 15 is fixedly installed with a wire pressing column 16. A fixing block 17 is fixedly installed on the moving plate 6 corresponding to the end position of the wire pressing column 16.

[0025] The cylinder 15 drives the wire pressing column 16 to move, pressing the welding wire between the wire pressing column 16 and the fixing block 17 for fixing the position of the welding wire.

[0026] As shown Figures 1 to 6 As shown, a first guide rail 18 is fixedly installed on one side of the fixing frame 1. The mounting plate 5 is slidably installed outside the first guide rail 18. A first motor 19 is fixedly installed at the position corresponding to the bottom end of the mounting plate 5 in the middle of the fixing frame 1. The output end of the first motor 19 passes through the fixing frame 1 and is fixedly installed with a first rotating block 20. A guide rod 21 is fixedly installed at the bottom of the mounting plate 5. The guide rod 21 is slidably connected to the middle of the first rotating block 20.

[0027] The first motor 19 drives the first rotating block 20 to rotate. By sliding the guide rod 21 in the middle of the first rotating block 20, the first rotating block 20 will be driven to push the guide rod 21, driving the mounting plate 5 to move laterally, pulling the welding wire to the shearing angle, which is convenient for subsequent shearing of the welding wire.

[0028] As shown Figures 1 to 6 As shown, a second guide rail 22 is fixedly installed outside the mounting plate 5. The moving plate 6 is slidably installed outside the second guide rail 22. A second motor 23 is fixedly installed on one side of the top end of the mounting plate 5. The output end of the second motor 23 passes through the mounting plate 5 and is fixedly installed with a second rotating block 24. One end side of the second rotating block 24 is rotatably connected to the top end of the moving plate 6 through a pin and connected with a connecting rod 25.

[0029] The second motor 23 drives the second rotating block 24 to rotate. Through the connection between the second rotating block 24 and the moving plate 6 by the connecting rod 25, the moving plate 6 will be driven to descend, and the welding wire passes through the product for feeding the welding wire on the product.

[0030] As shown Figures 1 to 6 As shown, a smoke suction pipe 26 is installed on the fixing frame 1.

[0031] It is used to absorb the smoke and dust generated during welding, improving the working environment of the workpiece.

[0032] The present utility model provides a laser soldering device with an automatic wire cutting function, and the specific working principle is as follows:

[0033] When the device is in use, the product is transported to the inside of the product positioning tooling 8 and enters the welding wire welding position, and then the product is clamped by the straightening clamping claw 9, and the wire reel 3 is controlled to rotate by the wire pay-off motor 2. The welding wire enters the threading needle 7 from the welding wire reel 3 through the tensioning wheel 4, and the wire pressing column 16 is driven to move by the cylinder 15 to press the welding wire between the wire pressing column 16 and the fixed block 17. The second motor 23 drives the second rotating block 24 to rotate, and the connection between the second rotating block 24 and the movable plate 6 through the connecting rod 25 will drive the movable plate 6 to descend, and the welding wire passes through the product. The product positioning tooling 8 clamps the welding wire head, and the pressure is cancelled. The wire column 16 presses the welding wire and controls the movable plate 6 to rise. At the same time, the welding wire is released from the welding wire roll 3 through the operation of the wire-releasing motor 2. After the movable plate 6 is controlled to rise, the first motor 19 drives the first rotating block 20 to rotate and the guide rod 21 slides in the middle of the first rotating block 20, which will drive the first rotating block 20 to push the guide rod 21, which will drive the mounting plate 5 to move sideways, pull the welding wire to the shearing angle, and tighten the welding wire. The tin feeding module 11 feeds tin to the upper part of the product, and the laser welding gun 10 heats the tin wire and welds it to the surface of the product. After welding is completed, the wire cutting module 12 moves forward to shear the welding wire.
