Description

Technical Field

[0002] Quartz wire is widely used as a suspension wire in a torsion balance system due to its high strength and low expansion coefficient. It is used to suspend samples of test objects. The signal-to-noise ratio is one of the important indicators for the performance evaluation of a milligram-level torsion balance. The improvement of the signal-to-noise ratio can be solved by reducing the angle of dissipation by 90 degrees. Studies have found that whether it is a torsion pendulum or a simple pendulum, the dissipation mainly comes from the connection, and the connection method of welding at the connection can effectively reduce the dissipation. Therefore, the use of welding to connect quartz wire and samples can effectively improve the performance of the milligram-level torsion pendulum.

[0015] In the present invention, the beneficial effects of the quartz wire welding device based on laser melting are: This solution presses the two handle plates facing the front in turn, and the handle plates drive the extrusion plate and the rubber plate to leave the rubber pad. The elastic plate compresses the spring and slides into the elastic groove, and the quartz wire is placed in the quartz wire placement groove.

[0016] This solution continues to install the quartz wire into the quartz wire placement groove. After welding is completed, the four-sided column is rotated 90 degrees again and welding is continued. At this time, the two quartz wires that have completed welding for the first time are moved to the top of the collection hole, and the extrusion mechanism squeezes the handle plate, so that the handle plate drives the rubber plate to leave the rubber pad, releases the fixation of the quartz wire, and causes the quartz wire to fall from the quartz wire placement groove into the collection hole, and is finally collected by the collection box. At the same time, the quartz wire continues to be welded. After welding is completed, the four-sided column is controlled to continue to rotate 90 degrees. The handle plate squeezes the extrusion inclined surface on the extrusion strip through the inclined surface, so that the extrusion strip moves downward along the rectangular strip and compresses the compression spring until the quartz wire that has completed welding for the first time leaves the collection hole and moves to the initial position.
