Description

Technical Field

[0001] The present invention relates to the technical field of laser welding devices, and particularly to a quartz wire welding device based on laser melting. Background Art

[0002] Due to characteristics such as high strength at 90 degrees and low coefficient of thermal expansion, quartz wires are widely used as suspension wires in torsion balance systems for suspending test object samples. The signal-to-noise ratio is one of the important indicators for evaluating the performance of milligram-level torsion balances. The improvement of the signal-to-noise ratio can be achieved by reducing the dissipated angular 90 degrees; research has found that whether it is a torsion pendulum or a simple pendulum, the dissipation mainly comes from the connection points, and the use of a welding connection method at the connection points can effectively reduce the dissipation; therefore, using a welding method to connect quartz wires and samples can effectively improve the performance of milligram-level torsion pendulums.

[0003] Publication (Announcement) No.: CN118577934B discloses a micron-level quartz wire welding device and method based on laser melting. The welding device includes a frame, and arranged on the frame are: a suspension tooling for suspending micron-level quartz wires, with the ends of the micron-level quartz wires being quartz rods; a sample stage for supporting a sample below the micron-level quartz wires; a laser welding module for providing a laser beam with adjustable power to form a melting zone circumferentially at the end of the micron-level quartz wire to achieve the welding of the micron-level quartz wire and the sample; an imaging module for detecting the positions of the micron-level quartz wire and the sample; and a position adjustment module for adjusting the relative positions of the micron-level quartz wire and the sample and adjusting the distance between the laser output by the laser welding module to the surface of the micron-level quartz wire and the bottom of the end of the micron-level quartz wire based on the information detected by the imaging module in real time to ensure the alignment of the micron-level quartz wire and the sample. Through the welding device of the present application, the welding quality of the micron-level quartz wire and the sample can be improved.

[0004] The existing laser welding devices are inconvenient to operate and use. When welding quartz wires, it is necessary to constantly stop the machine to replace the quartz wires, and the welded quartz wires cannot be automatically collected. Summary of the Invention

[0016] Preferably, the quartz wire placing mechanism includes two fixing plates, both of which are fixedly installed on the top of the support table and on both sides of the collection hole. Rotating rods are rotatably installed on both fixing plates through bearings. Synchronous motors are installed on the outer sides of both fixing plates. Output shafts of the two synchronous motors are fixedly installed with the two rotating rods. The inner ends of the two rotating rods are fixedly installed with the same quadrilateral column. Quartz wire placing grooves are formed on the four sides of the quadrilateral column. Welding grooves are formed at the central positions of the four sides of the quadrilateral column. The welding grooves communicate with the quartz wire placing grooves. The two synchronous motors drive the quadrilateral column to rotate through the two rotating rods. The quartz wire placing grooves are used to place two quartz wires to be welded. The welding grooves are aligned with the laser welding heads, and the welding heads of the two quartz wires are welded at the positions of the welding grooves.

[0017] Preferably, quadrilateral arc-shaped blocks are fixedly installed on the outer sides of both rotating rods. Arc-shaped grooves are provided on the four sides of the quadrilateral arc-shaped blocks. The force-bearing rods are slidably connected to the sides of the quadrilateral arc-shaped blocks through balls. The two synchronous motors drive the two rotating rods to rotate. The two rotating rods drive the two quadrilateral arc-shaped blocks to rotate. The two quadrilateral arc-shaped blocks rotate 90 degrees. During this process, the balls at the bottom ends of the force-bearing rods slide on the outer sides of the quadrilateral arc-shaped blocks. The balls transmit the reaction force to the force-bearing rods. The force-bearing rods push the mounting plate upward. The mounting plate compresses the corresponding return spring and moves upward. The mounting plate drives the laser welding machine and the transparent protective glass to move upward and away from the quartz wire placing mechanism. When the balls move to the positions of the arc-shaped grooves, due to the elastic force of the return spring, the mounting plate pushes the laser welding machine to drive the transparent protective glass to move downward and close to the position of the welding groove.

[0018] Preferably, two rubber pads are fixedly installed on the inner wall of one side of the quartz wire placing groove. The two rubber pads are symmetrically arranged on both sides of the welding groove. Two elastic force grooves are formed on the inner wall of the other side of the quartz wire placing groove. Quartz wire fixing mechanisms are arranged in the two elastic force grooves. The quartz wire fixing mechanisms cooperate with the corresponding rubber pads to press and fix the quartz wires.

[0019] Preferably, the quartz wire fixing mechanism includes an elastic plate. The elastic plate is slidably installed in the elastic force groove. A plurality of springs are fixedly installed between the elastic plate and the elastic force groove. An extrusion plate is fixedly installed on the outer side of the elastic plate. A rubber plate is fixedly installed on the inner side of the extrusion plate. Press the two handle plates facing the front in sequence. The handle plates drive the extrusion plate and the rubber plate away from the rubber pad. The elastic plate compresses the spring and slides into the elastic force groove. Place the quartz wire in the quartz wire placing groove. Then release the handle plates. Due to the elastic force of the spring, the rubber plate cooperates with the rubber pad to press and fix the quartz wire.

[0020] Preferably, a handle plate is fixedly installed on the top of the extrusion plate. An inclined surface is arranged on the side of the handle plate.

[0021] Preferably, an extrusion mechanism is fixedly installed on the top of the support platform. The extrusion mechanism includes a rectangular strip, which is fixedly installed on the outside of the top of the support platform near the collection hole. An extrusion strip is slidably installed on the outside of the rectangular strip. A compression spring groove is formed at the bottom of the extrusion strip. A plurality of compression springs are fixedly installed between the rectangular strip and the compression spring groove. An extrusion inclined surface is arranged at the top of the extrusion strip, and the extrusion inclined surface is matched with the inclined surface; the extrusion mechanism extrudes the handle plate, so that the handle plate drives the rubber plate to leave the rubber pad, releases the fixation of the quartz fiber, and enables the quartz fiber to fall into the collection hole from the quartz fiber placement groove, and finally is collected by the collection box.

[0022] In the present invention, the beneficial effects of the quartz fiber welding device based on laser melting are as follows:

[0023] In this solution, the two handle plates facing the front are pressed in sequence. 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. The quartz fiber is placed in the quartz fiber placement groove, and then the handle plates are released. Through the elastic force of the spring, the rubber plate is matched with the rubber pad and the taken quartz fiber is pressed and fixed. The two quartz fibers are fixed in the same quartz fiber placement groove, and the joints of the two quartz fibers are located in the welding groove, which is convenient for fixing the quartz fiber and improves the stability of welding;

[0024] In this solution, two synchronous motors drive two rotating rods to rotate. The two rotating rods drive two quadrilateral arc-shaped blocks to rotate. The two quadrilateral arc-shaped blocks rotate 90 degrees. During this process, the balls at the bottom of the force-bearing rod slide on the outside of the quadrilateral arc-shaped blocks. The balls transmit the reaction force to the force-bearing rod. The force-bearing rod pushes the mounting plate upward. The mounting plate compresses the corresponding return spring and moves upward. The mounting plate drives the laser welding machine and the transparent protective glass to move upward and away from the quartz fiber placement mechanism; when the balls move to the position of the arc groove, through the elastic force of the return spring, the mounting plate pushes the laser welding machine to drive the transparent protective glass to move downward and close to the position of the welding groove. The laser welding head on the laser welding machine is used to perform laser welding on the joint positions of the two quartz fibers. The provided transparent protective glass can play a protective role during laser welding. During the welding process, the two quartz fibers can be fixed in another quartz fiber placement groove without stopping the machine. The two quadrilateral columns are rotated 90 degrees again by the two synchronous motors, and the two un-welded quartz fibers move under the laser welding machine to wait for welding, and the quartz fiber welding work can be carried out without stopping the machine.

[0025] In this solution, the quartz wire is continuously installed 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 move directly above the collection hole, and the extrusion mechanism extrudes the handle plate, causing the handle plate to drive the rubber plate away from the rubber pad, releasing the fixation of the quartz wire, so that the quartz wire falls from the quartz wire placement groove into the collection hole, and finally is collected through 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 rotate 90 degrees continuously. The handle plate squeezes the extrusion slope on the extrusion bar through the inclined plane, causing the extrusion bar to move downward along the rectangular bar and compress 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. The four-sided column rotates 360 degrees to complete a working cycle. The quartz wire is continuously installed into the quartz wire placement groove, enabling processing without stopping the machine and automatically collecting the quartz wire;

[0026] The structure of the present invention is simple, which can facilitate the fixation of the quartz wire, can perform welding processing on the quartz wire without stopping the machine, improve work efficiency, and can automatically collect the quartz wire during the welding processing.

[0058] Working principle: When in use, power is connected and the control cabinet 2 can be used for electrical control. This is prior art and will not be elaborated here. Press the two handle plates 652 facing forward in sequence. The handle plates 652 drive the pressing plate 651 and the rubber plate 656 away from the rubber pad 642. The elastic plate 654 compresses the spring 655 and slides into the elastic groove 643. Place the quartz wire in the quartz wire placement groove 644, and then release the handle plate 652. Due to the elastic force of the spring 655, the rubber plate 656 cooperates with the rubber pad 642 to hold and tightly fix the quartz wire. Fix the two quartz wires in the same quartz wire placement groove 644, and the joints of the two quartz wires are located in the welding groove 641;

[0059] The two synchronous motors 62 drive the two rotating rods to rotate. The two rotating rods drive the two quadrilateral arc-shaped blocks 63 to rotate. The two quadrilateral arc-shaped blocks 63 rotate 90 degrees. During this process, the balls 831 at the bottom of the force-bearing rod 83 slide on the outside of the quadrilateral arc-shaped block 63. The balls 831 transmit the reaction force to the force-bearing rod 83. The force-bearing rod 83 pushes the mounting plate 8 upward. The mounting plate 8 compresses the corresponding return spring 82 and moves upward. The mounting plate 8 drives the laser welding machine 7 to drive the transparent protective glass 71 upward and away from the quartz wire placement mechanism 6; When the balls 831 move to the position of the arc groove 631, due to the elastic force of the return spring 82, the mounting plate 8 pushes the laser welding machine 7 to drive the transparent protective glass 71 downward and close to the position of the welding groove 641. The laser welding head on the laser welding machine 7 performs laser welding on the joint positions of the two quartz wires. The provided transparent protective glass 71 can play a protective role during laser welding. During the welding process, the two quartz wires can be fixed in another quartz wire placement groove 644 without shutting down the machine. Rotate the quadrilateral column 64 by 90 degrees again through the two synchronous motors 62, and the two un-welded quartz wires move below the laser welding machine 7 to await welding;

[0060] Continue to install the quartz wire into the quartz wire placement groove 644. After completing the welding, rotate the quadrilateral column 64 by 90 degrees again and continue welding. At this time, the two quartz wires that completed welding for the first time move directly above the collection hole 33. At this time, the extrusion mechanism 9 extrudes the handle plate 652, causing the handle plate 652 to drive the rubber plate 656 away from the rubber pad 642, releasing the fixation of the quartz wire, so that the quartz wire falls from the quartz wire placement groove 644 into the collection hole 33 and is finally collected through the collection box 31. At the same time, the quartz wire continues to be welded. After the welding is completed, control the quadrilateral column 64 to continue rotating by 90 degrees. The handle plate 652 squeezes the extrusion slope 95 on the extrusion bar 93 through the slope 653, causing the extrusion bar 93 to move downward along the rectangular bar 91 and compress the compression spring 92 until the quartz wire that completed welding for the first time leaves the collection hole 33 and moves to the initial position. The quadrilateral column 64 rotates 360 degrees to complete a working cycle. Continue to install the quartz wire into the quartz wire placement groove 644, and it is possible to process without stopping and automatically collect the quartz wire. Embodiment 2

The eight cylinders 12 push the eight rollers 13 to move downward and contact the ground. By supporting with the four rollers 13, it is convenient to move the control cabinet 2 and the support table 3. The eight cylinders 12 drive the eight rollers 13 into the eight support cylinders 11. Through the eight support cylinders 11, the stability of placing the control cabinet 2 and the support table 3 can be improved.
