Description

Technical Field

[0001] The present invention relates to the technical field of welding, in particular to a quartz welding wire melting device. Background Art

[0002] The quartz wire melting and filling process, a key welding technology in the manufacture of quartz products, has traditionally relied on manual labor. Specifically, the end of the quartz wire is melted at high temperature using an oxyhydrogen torch, and the molten quartz wire is then manually filled into the pre-set joint gap of the quartz product. During this operation, the operator must hold the oxyhydrogen torch in operation throughout the entire process. The torch flame temperature can reach over 1200°C, posing not only an operational safety hazard of high-temperature burns, but also operator fatigue caused by holding high-temperature equipment for extended periods, leading to unexpected risks. Furthermore, the heat treatment process for the quartz wire requires the torch flame to continuously and stably act on specific parts of the wire to maintain a molten state. This places extremely high demands on the spatial positioning accuracy and movement stability of the operator's handheld torch. Any slight jitter or deviation may cause uneven melting of the wire, affecting welding quality. In addition, in order to achieve uniform heating of the end of the quartz welding wire, the operator needs to simultaneously perform the axial rotation operation of the welding wire during the heating process. This complex action that requires simultaneous control of the welding torch posture and the rotation of the welding wire not only increases the complexity of the operation, but also increases the labor intensity and safety risks because the fingers need to continuously contact the high-temperature working area. As a result, the existing process has technical defects such as low operating efficiency, poor quality consistency and prominent safety hazards. Summary of the Invention

DETAILED DESCRIPTION

[0025] To facilitate understanding of the present invention, the present invention will be described more fully below with reference to the accompanying drawings. Preferred embodiments of the present invention are shown in the accompanying drawings. However, the present invention may be implemented in many different forms and is not limited to the embodiments described herein. Rather, these embodiments are provided to provide a more thorough and comprehensive understanding of the present disclosure.

[0026] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art of the present invention. The terms used in the specification of the present invention herein are only for the purpose of describing specific embodiments and are not intended to limit the present invention.

[0027] Specific embodiments of the present invention are described below with reference to the accompanying drawings.

[0028] Example 1

[0029] In this embodiment, a quartz wire melting device is proposed. Figure 1-Figure 3 The quartz welding wire melting device includes a first frame 1 and a second frame 4 behind the first frame 1, wherein the first frame 1 is equipped with a manipulator interface 15, the manipulator interface 15 is connected to an automated device such as a manipulator arm, and there are no obstacles in the axis area of the first frame 1. Figure 1 The quartz welding wire shown enters the first frame 1 through the wire inlet tube 10. A first motor 2 is also installed in the first frame 1, and the first motor 2 is used to drive the second frame 4 to rotate. Further, the first motor 2 is equipped with a hollow reduction structure, and the hollow area of the hollow reduction structure is provided for the quartz welding wire to pass through. In addition, a flange 3 is provided, which serves as a receiving structure to rigidly connect the hollow reduction structure with the second frame 4 (a channel for the quartz welding wire to pass through is provided in the center of the flange 3). After the connection, the second frame 4 will rotate around the quartz welding wire under the drive of the first motor 2.

[0030] See also Figure 1-Figure 3 The quartz welding wire passes through the flange 3 and enters the second frame 4. In this embodiment, a feeding mechanism is set in the second frame 4. The feeding mechanism includes a pressing portion 7 and a concave wheel 8 that roll and contact the quartz welding wire in relative directions within the second frame 4, and a second motor 5. The shaft structure of the second motor 5 is connected to the concave wheel 8. After the connection, when the second motor 5 drives the concave wheel 8, the quartz welding wire can be moved in the direction of its own axis.

[0031] In this embodiment, the clamping portion 7 and the concave wheel 8 are not only used for feeding, but also serve as a clamp for the quartz welding wire. Specifically, when the first motor 2 drives the second frame 4 to rotate around the quartz welding wire, the clamping portion 7 and the concave wheel 8 in the second frame 4 will act as a clamp to drive the quartz welding wire to rotate, forming a rotation plus linear composite motion mode, so that the welding wire can be spirally heated evenly during the subsequent melting process, preventing uneven melting of the welding wire from affecting the welding quality.

[0032] See also Figure 1 The quartz welding wire passes through the first frame 1 and then into the second frame 4, and then extends outward from the wire outlet tube 9 at the tail end of the second frame 4. In this embodiment, a melting zone is established in the outward extending area of the quartz welding wire. Specifically, there are two welding torches outside the first frame 1, namely the first welding torch 12 and the second welding torch 14. The flame points of the two welding torches are both directed to the end of the outward extending portion of the quartz welding wire. As is known to all, the temperature of the flame is different in different areas. Therefore, in order to adjust the position of the flame relative to the quartz welding wire, a special torch adjustment unit is provided. Please continue to read Figure 1 The first welding torch 12 is installed on the first welding torch adjusting part 11 set on the outside of the first frame 1, and the second welding torch 14 is installed on the second welding torch adjusting part 13 set on the outside of the first frame 1. The first welding torch adjusting part 11 and the second welding torch adjusting part 13 can adjust the front and rear positions of the corresponding welding torches, and can also adjust the pitch angle of the welding torches, accurately control the flame action area, optimize the melting effect, and improve the consistency of welding quality.

[0033] See also Figure 3 The second frame 4 is provided with a bracket 6, which is preferably an L-shaped bracket. The bracket 6 is a fixing structure for the pressing portion 7 and the concave wheel 8. In this embodiment, the pressing portion 7 can adjust the pressing force of the quartz welding wire. Figure 3 As shown, the pressing part 7 includes a wheel frame 702 with one end connected to the bracket 6. The other end of the wheel frame 702 is a pressure regulating structure. The center of the wheel frame 702 is a protrusion extending outward. The protrusion is installed with a pressure wheel 707 (the pressure wheel 707 is a non-powered wheel) for rolling contact with the quartz welding wire. Please continue to refer to Figure 3The pressure regulating structure includes a threaded rod 701 with one end axially connected to the bracket 6, and the threaded rod 701 penetrates the wheel frame 702 and extends outward. Figure 3 The ram's horn knob 703 shown is screwed onto the outwardly extending portion of the threaded rod 701. Between the ram's horn knob 703 and the wheel frame 702 is a spring 705 that is sleeved on the threaded rod 701. On both sides of the spring 705 are a first gasket 704 and a second gasket 706 that increase the contact area. From the above description, it can be seen that the ram's horn knob 703 is a switch for controlling the clamping force. Specifically, when the ram's horn knob 703 is rotated on the threaded rod 701, the compression degree of the spring 705 can be adjusted, the clamping pressure on the welding wire can be flexibly controlled, friction damage can be reduced, and the stable delivery of welding wires of different diameters can be adapted.

In order to make the description concise, not all possible combinations of the technical features in the above-mentioned embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0035] The above-described embodiments merely illustrate several implementations of the present invention, and while their descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent. It should be noted that a person skilled in the art would be able to make numerous variations and improvements without departing from the spirit of the present invention, all of which fall within the scope of protection of the present invention.
