Description

Technical Field

[0001] The utility model relates to the technical field of welding, in particular to an optical fiber equipment welding machine. Background Art

[0002] The working principle of the fiber optic fusion splicer is to use a high-voltage electric arc to melt the two optical fiber sections while using a high-precision motion mechanism to smoothly advance the two optical fibers into one, so as to achieve the coupling of the optical fiber mode field. It is mainly used in optical cable line engineering construction, line maintenance, emergency repair, production testing of optical fiber devices, and research and teaching in scientific research institutes in optical communications.

[0003] After searching, the Chinese patent with the announcement number CN218855925U discloses a fiber optic equipment welding machine; it includes a laser welding head, a positioning mechanism and a fixed seat for fixing the strain gauge, and the two sides of the fixed seat are provided with fiber clamps for fixing the optical fiber, and the fixed seat and one of the fiber clamps are respectively connected with a positioning mechanism, and the positioning mechanism includes a positioning seat, a three-dimensional translation stage for driving the positioning seat to move linearly in the X-axis direction, the Y-axis direction and the Z-axis direction, and the fiber clamp located on the positioning seat is also connected with a tension gauge. The utility model fixes the strain gauge in the groove of the fixed seat, and the two sides of the fixed seat are provided with fiber clamps for fixing the optical fiber, and one of them is also connected with a tension gauge, which can monitor the tension on the optical fiber to avoid the influence of excessive or insufficient tension on the welding quality, and the fiber clamp connected with the tension gauge is arranged on the three-dimensional translation stage, which can quickly adjust the position of the fiber clamp to ensure the tension of the optical fiber during welding.

[0004] However, in the above technology, tension is generated by the movement of the optical fiber clamp, and the tension on the optical fiber is detected by a tensile gauge. During welding, one end of the optical fiber is fixed by the fusion welding machine and the other end of the optical fiber droops due to its own gravity. If the other end is in a lower position, it is easy for the two ends of the optical fiber to bend at a large angle. Bending at too large an angle can easily cause the optical fiber made of glass to bend or break, thereby affecting the performance of the optical fiber. Utility Model Content
