With the continuous development of the digital age and the continuous extension of the 5G industry, the investment requirements of the development of the Internet of things and the cloud technology and the high-speed Internet requirements of bandwidth expansion are continuously laid in various countries to meet the transmission requirements of rapid and reliable data.
The basic requirement of submarine cables is to protect the inherent mechanical and optical properties of the optical fibers therein, preventing breakage of the fibers during construction and use, to maintain stable transmission characteristics. The stainless steel optical unit is the core of the submarine cable and determines the transmission characteristics of the submarine cable.
The submarine optical cable is challenged by external forces such as seawater pressure, biological biting, ship anchor collision, dragging and the like, and has very strict requirements on tensile force resistance and lateral pressure resistance. To improve the lateral pressure resistance, the optical fiber unit should be disposed at the center, and the smaller the unit size should be, the better. This not only improves the lateral pressure resistance but also optimizes the bending resistance. In order to ensure the long service life and stable performance of the optical fiber unit, the fully-sealed metal tube is necessary for protecting the optical fiber, and is formed by longitudinally wrapping and welding a 316 stainless steel band with a certain thickness, and the stainless steel tube is filled with water-blocking fiber paste without hydrogen evolution. In the production of the existing submarine optical cable longitudinally-covered stainless steel optical unit, the problem is that due to the defects of the existing laser welding technology, a laser welding gun cannot immediately follow the swing of a tiny longitudinally-covered welding line to automatically adjust the welding point, so that the longitudinally-covered stainless steel optical unit is high in welding leakage rate in production, and once welding leakage occurs, the device is stopped to perform manual repair welding, so that the repair welding operation consumes time, and the quality of the welding line cannot be guaranteed.

Detailed Description
The present invention will be described in detail with reference to the accompanying drawings and examples.
Referring to fig. 1, 2, 3 and 4, an intelligent-identification automatic following laser welding system for an ocean communication light unit comprises a vision control unit 1, a laser welding unit 2 and a multi-dimensional servo automatic tracking unit 3.
The visual control unit 1 comprises an industrial camera 101, a touch man-machine interaction operation assembly 102 and a programmable controller 103.
The laser welding unit 2 comprises a welding gun mounting seat 201 and a laser welding gun 202.
The multi-dimensional servo automatic tracking unit 3 comprises a composite platform mounting frame 301, a mounting bottom plate 302, a Z-direction screw rod assembly 303, a Z-direction rail assembly 304, a Z-direction servo motor 305, a motor belt pulley 306, a synchronous belt 307, a screw rod belt pulley 308, a composite moving platform 309, an X-direction servo motor 310, a Y-direction servo motor 311 and a rotary servo motor 312.
Further, the laser welding unit 2 is arranged on the multi-dimensional servo automatic tracking unit 3, and the vision control unit 1 is independently arranged and fixed;
further, in the vision control unit 1, the lens of the industrial camera 101 is opposite to the laser welding point, and the touch type man-machine interaction operation assembly 102 is mounted on the external frame and is connected with the industrial camera 101 and the programmable controller 103 by adopting a communication cable.
The touch man-machine interaction operation assembly 102 can be provided with front-back, up-down, left-right and rotary touch buttons, and before welding starts, the front-back, up-down, left-right and rotary touch buttons of the laser welding gun 202 can be manually controlled to rotate to a proper position and then kept fixed, so that the focus of the laser welding gun 202 is ensured to fall on a forming seam of the longitudinally-covered stainless steel light unit (4). Meanwhile, the touch buttons on the touch man-machine interaction operation assembly 102, which are front and back, up and down, left and right, and rotate, can also be used in repair welding operation.
Further, in the laser welding unit 2, the lower end of the welding gun mounting seat 201 is fixed on the rotating base of the composite moving platform 309, and the laser welding gun 202 is mounted on the upper end of the welding gun mounting seat 201. And is rotated about the axis of the rotating base by the gun mount 201 driven by the composite moving platform 309.
The laser welding gun 202 uses laser beam as energy source to impact the stainless steel longitudinal wrapping seam so as to achieve the purpose of welding. The laser beam can be focused in a small area, and the beam spot size is one of the most important variables for laser welding because it determines the power density and penetration. The welding speed has a great influence on the penetration, and the penetration becomes shallow by increasing the speed, but too low speed can cause excessive melting of materials and penetration of workpieces. Therefore, there is a suitable welding speed range for a certain laser power and a certain thickness of a specific material, and a maximum penetration is obtained at a corresponding speed value therein. In the application of the invention, the proper laser generator and conduction optical fiber are selected, and the energy required by the production speed change is met by adjusting the power of the laser, so that the qualified weld quality can be achieved without damaging the optical fiber in the pipe. In welding, the focal position is critical in order to maintain a sufficient power density. The variation in the relative position of the focal spot and the workpiece surface directly affects the weld width and depth (penetration). See fig. 4 for a graph of the relationship between laser power, welding speed and penetration in an intelligent-recognition marine communication light unit automatic following laser welding system in an embodiment of the invention.

The motor belt wheel 306 is connected with the Z-direction servo motor 305, the screw rod belt wheel 308 is connected with the Z-direction screw rod assembly 303, and meanwhile, the motor belt wheel 306 is connected with the screw rod belt wheel 308 through the synchronous belt 307, so that kinetic energy of the Z-direction servo motor 305 is transferred to the Z-direction screw rod assembly 303, and the composite platform mounting frame 301 and the upper assembly thereof can reciprocate along the Z-direction guide rail assembly 304 under the driving of the Z-direction screw rod assembly 303. The composite moving platform 309 is installed on the vertical surface of the composite platform installation frame 301, and has three input ports below, and is respectively installed with an X-direction servo motor 310, a Y-direction servo motor 311 and a rotary servo motor 312, and is respectively used for controlling the upper welding gun installation seat 201 to drive the laser welding gun 202 to link along the X-direction, the Y-direction and the self-angle.
The formed longitudinal stainless steel light unit forming joint position is sampled through an industrial camera, a programmable controller and a control program in the vision control unit 1, and the multi-dimensional servo automatic tracking unit 3 is controlled by the control program to track, so that the synchronous linkage of three dimensions of the laser welding gun 202X/Y/Z and the self angle is realized, and the laser welding gun 202 is ensured to immediately follow the swinging of the welding seam to rotate.
When the welding work starts, the industrial camera 101 continuously detects the current center position of the welding point, calculates the offset of the focus of the laser welding gun 202 relative to the center of the set welding line, transmits the real-time offset to the programmable controller 103 through a communication cable, and the programmable controller 103 controls the actions of the Z-direction servo motor 305, the X-direction servo motor 310, the Y-direction servo motor 311 and the rotary servo motor 312 according to the magnitude and the positive and negative of the offset, so that the focus of the laser welding gun 202 is always ensured to fall on the stainless steel light unit forming joint.
Further, the multi-dimensional servo automatic tracking unit 3 has a Z-direction movable distance of 50mm and a repeated movement accuracy of 0.1mm. The x-direction movable distance of the composite movable platform 309 was 25mm, and the repeated movement accuracy was 0.1mm.
