Description
Technical Field

[0002] A CO2 laser welding machine is a device that uses the laser light generated by a CO2 laser as a heat source to weld materials, and it has important applications in many fields. The core component of a CO2 laser welding machine is a CO2 laser, which can generate a high-energy laser beam. When the laser beam is irradiated onto the surface of the material to be welded, the material absorbs the laser energy and quickly melts and solidifies, thereby achieving the connection of the materials. For example, in the field of fiber-optic communications, it can be used to weld optical fibers, and its high-precision welding can ensure the efficient transmission of optical signals in optical fibers; in the field of material processing, it can weld materials such as plastics and metals. For example, in the production and processing of automotive parts, some parts with complex shapes can be precisely welded using a CO2 laser welding machine.
[0003] When welding optical fibers, existing CO2 laser welding machines often suffer from inaccurate positioning of the fiber ends, due to the thin structure and small end area of the fibers themselves, as well as the low fiber strength and inconvenient clamping and adjustment. This negatively impacts the quality of the weld. Therefore, it is necessary to propose a CO2 laser welding machine to address this issue. Utility Model Content

[0011] In summary, due to the adoption of the above technical solution, the beneficial effects of this application are:
[0012] 1. In this application, through the above design, when using this device to fuse two optical fibers, first start the double-headed motor to drive the screws on the two output shafts to rotate. At this time, the two sliders move toward each other, so that the two guide cylinders at the bottom ends of the front sides of the two right-angle rods are docked and fit together. Then start the cylinder to contract, so that the push-pull rod pulls the piston in the piston cylinder backward to create a negative pressure environment inside the piston cylinder.

Then the staff inserts the two optical fibers from the outer end of the sleeve respectively until they pass through the guide cylinder and reach the guide cylinder. The inner ends of the two optical fibers are connected to each other. At this time, under the guidance of the guide cylinder, the two optical fibers can be connected together more accurately. After this step is completed, the cylinder is started to extend. Under the same principle, the air in the piston cylinder comes to the airbag to replenish, causing the airbag to expand and clamp the optical fiber around to a fixed position. Then, the double-headed motor is started again to drive the two screws to rotate in the opposite direction, so that the two sliders drive the two guide cylinders to move outward through the right-angle rod and plug into the sleeve to expose the connecting part of the two optical fibers. Finally, the upper and lower laser heads are started to generate high heat to fuse the optical fibers to complete the work.
[0013] 2. In this application, through the above design, when the laser head fuses the optical fiber, welding smoke will be generated. At this time, after the laser head fuses for the first time, so that the two optical fibers have a certain welding and fixing strength with each other, the air pump is quickly started to generate negative pressure suction in the guide tube through the suction tube. At this time, when the laser head continues to fuse, the smoke from the fiber optic joint part will be drawn into the smoke collector through the opposite end of the guide tube for treatment to prevent the irritating gas generated by the welding from damaging the health of the staff.

The front end of the piston cylinder 14 is fixedly connected with an air pipe 21. The outer end of the sleeve 12 is internally provided with a circle of air bags 13 connected to the air pipe 21.
[0020] Through the above design, when using the device to fuse two optical fibers, first start the double-headed motor 5 to drive the screw rods 4 on the two output shafts to rotate. At this time, the two sliders 3 move toward each other, so that the two guide cylinders 9 at the bottom ends of the front sides of the two right-angle rods 8 are docked and fitted together. Then the cylinder 16 is started to contract, so that the push-pull rod 15 pulls the piston in the piston cylinder 14 backward to create a negative pressure environment inside the piston cylinder 14. At this time, the air bag 13 inside the outer end of the sleeve 12 draws air through the trachea 21 and contracts.

At this time, the two sliders 3 move toward each other, so that the two guide cylinders 9 at the bottom ends of the front sides of the two right-angle rods 8 are butted against each other, and then start the cylinder 16 to contract, so that the push-pull rod 15 pulls the piston in the piston cylinder 14 to move backward to create a negative pressure environment inside the piston cylinder 14. At this time, the air bag 13 inside the outer end of the sleeve 12 draws air through the trachea 21 and contracts.

Docking. At this time, under the guidance of the guide cylinder 9, the two optical fibers can be docked together more accurately. After this step is completed, the cylinder 16 is started to extend. Under the same principle, the air in the piston cylinder 14 comes to the airbag 13 to replenish, causing the airbag 13 to expand and clamp the optical fiber around to a fixed position. Then, the double-headed motor 5 is started again to drive the two screw rods 4 to rotate in the opposite direction, so that the two sliders 3 drive the two guide cylinders 9 to move outward through the right-angle rod 8 and plug into the sleeve 12 to expose the docking part of the two optical fibers. Finally, the upper and lower laser heads 6 are started to generate high heat to weld the optical fibers to complete the work.

At this time, after the laser head 6 fuses for the first time, so that the two optical fibers have a certain welding and fixing strength, the air pump 17 is quickly started to generate negative pressure suction in the guide tube 9 through the suction tube 18. At this time, when the laser head 6 continues to fuse, the smoke from the fiber optic joint part will be sucked into the smoke collector 19 through the opposite end of the guide tube 9 for treatment to prevent the irritating gas generated by the welding from damaging the health of the staff.
