Description

Technical Field

[0001] This utility model relates to the field of laser welding equipment technology, and in particular to a fiber laser welding machine with precise positioning. Background Technology

[0002] Fiber optic welding is a technique that uses a fiber optic welding machine to connect two sets of optical fibers. There are two main types: cold splicing and hot fusion. Cold splicing relies on manual operation using a cold splice, which is simple to operate but requires high technical skills. Cold splices are easily damaged, affecting connection stability and signal transmission. Hot fusion uses a fiber optic fusion splicer to melt the end faces of the optical fibers at high temperatures, making them fuse together. It has a high degree of automation, good splice quality, low loss, and high efficiency, and is suitable for scenarios with high requirements for connection quality.

[0003] In the current fiber optic welding process, the ends of two sets of optical fibers to be welded need to be accurately aligned. However, due to the lack of an effective structure for precise fiber positioning, the optical fibers are prone to positional shifts and angular deviations during actual operation, which makes it impossible for the ends to be welded to be fully aligned. This seriously affects the quality of fiber optic welding, increases welding loss, and reduces signal transmission performance. Utility Model Content

[0004] The purpose of this invention is to address the following shortcomings in the existing technology: In the current fiber optic welding process, it is necessary to accurately align the ends of two sets of optical fibers to be welded. However, due to the lack of an effective structure for precise fiber positioning, the optical fibers are prone to positional shifts and angular deviations during actual operation, resulting in the ends to be welded not being fully aligned. This seriously affects the fiber optic welding quality, increases welding loss, and reduces signal transmission performance. Therefore, this invention proposes a fiber laser welding machine with precise positioning.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: A precision-positioning fiber laser welding machine includes a platform. A fiber welding mechanism is provided on the upper surface of the platform. An mounting plate is fixedly installed on the upper surface of the platform. T-shaped sliding plates are symmetrically slidably mounted on the upper surface of the mounting plate. Multiple arc-shaped placement plates are fixedly mounted on the upper surface of the sliding plates via multiple support rods. A drive assembly for controlling the two sliding plates to move closer together is provided on the surface of the mounting plate. Multiple electric telescopic rods are fixedly installed on the upper surface of the sliding plates. A placement plate is fixedly installed at the top of the drive shaft of each electric telescopic rod. A positioning plate is fixedly installed on the lower surface of the placement plate via connecting rods. The multiple positioning plates are respectively located directly above the multiple placement plates. The upper surface of the platform is provided with an installation groove, and a telescopic rod is horizontally fixedly installed in the installation groove. A U-shaped baffle is fixedly installed on the free end of the telescopic rod by an L-shaped rod.

[0006] Preferably, the drive assembly includes a drive motor and a threaded rod with opposite thread directions at its left and right ends. The upper surface of the mounting plate is horizontally provided with a sliding groove. The threaded rod is horizontally rotatably installed in the sliding groove. The drive motor is fixedly installed on one side of the mounting plate, and the output shaft of the drive motor is fixedly connected to the threaded rod. The two sliding plates are symmetrically threaded onto the threaded rod.

[0007] Preferably, both the placement plate and the positioning plate have an anti-slip layer bonded to their surfaces, and the anti-slip layer is made of rubber.

[0008] Preferably, the upper surface of the baffle is provided with a heat dissipation component, which is used to accelerate the heat dissipation of the laser head in the fiber welding mechanism.

[0009] Preferably, the heat dissipation component includes an arc-shaped copper sheet, which is fixedly connected to the upper surface of the baffle via an L-shaped connecting rod.

[0010] Preferably, a light-shielding partition is fixedly installed at the bottom of the copper sheet, and the light-shielding partition is used to cover the bottom of the laser head in the fiber welding mechanism.

[0011] Compared with the prior art, the beneficial effects of this utility model are: 1. Through the cooperation of multiple electric telescopic rods, multiple positioning plates and baffles, the precise positioning of multiple sets of optical fibers of different sizes to be welded can be completed quickly, so that the ends of the optical fibers to be welded can be accurately connected. At the same time, multiple optical fibers to be welded can be positioned and welded at the same time, which improves the welding efficiency. 2. The copper sheet can be attached to the outer surface of the welded laser head, which can quickly conduct away the heat generated by the laser head, play a heat dissipation role, prevent the laser head from degrading or even being damaged due to excessive temperature, and extend the service life of the laser head. 3. When the copper sheet is in contact with the laser head, the light-shielding partition will also cover the bottom of the laser head, which can effectively block the scattered laser and residual laser that may be generated by the laser head, and prevent the operator from being injured due to accidental exposure to the laser when placing the optical fiber, thus greatly improving the safety during the use of the equipment.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0015] The terms used in this utility model, such as "upper", "lower", "left", "right", "middle" and "one", are only for clarity of description and are not intended to limit the scope of implementation of this utility model. Changes or adjustments to their relative relationships, without substantially altering the technical content, should also be considered as within the scope of implementation of this utility model.

[0016] Reference Figures 1-4 A precision-positioning fiber laser welding machine includes a platform 1. A fiber laser welding mechanism 2 is mounted on the upper surface of the platform 1. A mounting plate 3 is fixedly installed on the upper surface of the platform 1. T-shaped sliding plates 4 are symmetrically slidably mounted on the upper surface of the mounting plate 3. Multiple arc-shaped placement plates 6 are fixedly mounted on the upper surface of the sliding plates 4 via multiple support rods 5. Each pair of placement plates 6 located on the same horizontal line is symmetrically arranged. The surface of the mounting plate 3 is provided with a drive assembly for controlling the two sliding plates 4 to move closer to each other. The drive assembly includes a drive motor 11 and threads with opposite directions at both ends. The threaded rod 12 has a horizontal groove on the upper surface of the mounting plate 3. The threaded rod 12 is horizontally rotatably installed in the groove. The drive motor 11 is fixedly installed on one side of the mounting plate 3, and the output shaft of the drive motor 11 is fixedly connected to the threaded rod 12. Two sliding plates 4 are symmetrically threaded onto the threaded rod 12. Multiple electric telescopic rods 7 are fixedly installed on the upper surface of the sliding plates 4. A placement plate is fixedly installed at the top of the drive shaft of the electric telescopic rod 7. A positioning plate 8 is fixedly installed on the lower surface of the placement plate through a connecting rod. The multiple positioning plates 8 are located directly above the multiple placement plates 6.

[0017] The upper surface of the platform 1 is provided with an installation groove, in which a telescopic rod 9 is horizontally fixedly installed. A U-shaped baffle 10 is fixedly installed on the free end of the telescopic rod 9 by means of an L-shaped rod 15.

[0018] In the fiber optic welding mechanism 2, the welding head is initially at its highest position, and after welding, it automatically moves back to its highest position. The two sliding plates 4 are initially at their maximum distance. When welding fibers, first, place the two fibers to be welded into the two corresponding placement plates 6 located on the same horizontal line. Then, push the baffle 10 to retract the telescopic rod 9, positioning the baffle 10 between the two sliding plates 4. Next, push the two fibers located in the two placement plates 6 to bring their ends closer together and abut against the sides of the baffle 10. Finally, activate the electric telescopic rod 7 to lower the positioning plate 8, causing its lower surface to... After the upper surface of the optical fiber is pressed tightly against the positioning plate 8 and the placement plate 6, the baffle 10 is pulled to extend the telescopic rod 9, allowing the baffle 10 to move out from between the two sliding plates 4. Then, the drive motor 11 is started to control the threaded rod 12 to rotate, causing the two symmetrically threaded sliding plates 4 on the threaded rod 12 to move relative to each other. This allows the two sliding plates 4 to bring the two positioned optical fibers closer together until the ends of the two optical fibers to be welded are pressed together. Then, the optical fiber welding mechanism 2 can weld the ends of the pressed optical fibers, which is convenient and quick. After welding, the welding head of the optical fiber welding mechanism 2 will automatically move upward and reset. Then, the electric telescopic rod 7 is started to move the positioning plate 8 upward, releasing the positioning of the optical fiber, which can then be removed.

[0019] Meanwhile, the multiple placement plates 6 enable the device to quickly position and weld multiple optical fibers to be welded at the same time, improving welding efficiency.

[0020] The function of the baffle 10 is to ensure that the two optical fibers extend the same distance from the two placement plates 6, avoiding misalignment and offset problems caused by different extension lengths. This keeps the welding area in optimal condition, effectively reducing welding loss, improving the quality and stability of the weld joint, and ensuring efficient signal transmission. Operators no longer need to repeatedly adjust and measure the extension length of the optical fibers; they can simply place the optical fibers against both sides of the baffle 10 to quickly achieve consistent extension lengths. This reduces operation steps and time costs, improves welding efficiency, and lowers the difficulty and error rate of manual operation. Moreover, the fixed extension length standard ensures that each welding operation follows a uniform specification, guaranteeing the consistency of each welding point in batch welding operations. This helps improve the overall product quality and facilitates quality control and production management. The same extension length helps to evenly distribute heat and stress during the welding process, avoiding problems such as optical fiber damage or insufficient weld joint strength caused by stress concentration, thus enhancing the reliability and durability of the weld joint.

[0021] Both the placement plate 6 and the positioning plate 8 have anti-slip layers bonded to their surfaces. The anti-slip layers are made of rubber, which has good elasticity and adhesion, thereby increasing the friction between the placement plate 6 and the positioning plate 8 and the fiber contact surface.

[0022] The upper surface of the baffle 10 is provided with a heat dissipation component, which is used to accelerate the heat dissipation of the laser head in the fiber welding mechanism 2. The heat dissipation component includes an arc-shaped copper sheet 13, which is fixedly connected to the upper surface of the baffle 10 through an L-shaped connecting rod.

[0023] After the fiber welding is completed and the laser head in the fiber welding mechanism 2 moves and resets, the positioning of the welded fiber is released, and the welded fiber is removed. Then, the drive motor 11 is controlled to rotate the threaded rod 12, causing the two sliding plates 4 to move away from each other until the distance between them is at its maximum. Then, the baffle 10 is pushed to retract the telescopic rod 9 until the baffle 10 moves between the two sliding plates 4. At this time, the copper sheet 13 will also come into contact with the surface of the laser head. The copper sheet 13 has good thermal conductivity and can quickly conduct the heat generated by the laser head away, playing a heat dissipation role, preventing the laser head from degrading or even being damaged due to excessive temperature, and extending the service life of the laser head.

[0024] A light-shielding partition 14 is fixedly installed at the bottom of the copper sheet 13. The light-shielding partition 14 is used to cover the bottom of the laser head in the fiber welding mechanism 2.

[0025] When the copper sheet 13 is in contact with the laser head, the light-shielding partition 14 will also cover the bottom of the laser head, which can effectively block the scattered laser and residual laser that may be generated by the laser head, and prevent the operator from being injured due to accidental exposure to the laser when placing the optical fiber, thus greatly improving the safety of the equipment during use.

[0026] In this invention, the precise positioning of multiple sets of optical fibers of different sizes to be welded can be completed quickly through the cooperation of multiple electric telescopic rods 7, multiple positioning plates 8 and baffles 10, so that the ends of the optical fibers to be welded can be accurately connected. At the same time, multiple optical fibers to be welded can be positioned and welded at the same time, which improves the welding efficiency.

[0027] In this utility model, unless otherwise explicitly specified and limited, the terms "installation", "connection", "linking", "fixing", etc., should be interpreted broadly.

[0028] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
