The first heating nozzle 211 does not move during welding in the present application, and the quartz tube 11 and the quartz plate 12 rotate, which can make the heating more uniform and the welding quality better.

[0075] In the present application, the heating nozzle can spray flame to heat the upper end of the quartz tube 11 and the periphery of the quartz plate 12, so that the quartz tube 11 and the quartz plate 12 can be fused and welded together.

[0082] a movable frame 221, which is slidingly arranged on the rack 2 and can be close to or away from the rotating assembly 3;

[0083] an arc-shaped limiting block 222, which is fixed on the movable frame 221, the arc-shaped limiting block 222 has an arc-shaped surface 2221, which is used to simultaneously contact the upper end of the quartz tube 11 and the quartz plate 12;

[0087] In actual use, in order to ensure safety, a anti-dropping strip connected with the two insertion parts 71 can be further arranged to close the U-shaped piece.

[0088] In this embodiment, the material of the arc-shaped limiting block 222 is graphite.

[0090] The rotating component 31 includes a hollow body 311, and the lower end of the inner sidewall of the hollow body 311 has an annular support portion 312.

[0091] The flexible component 32 includes an annular body 321. The lower end of the outer wall of the annular body 321 has a flexible support portion 322. The flexible support portion 322 is located above the annular support portion 312. The flexible support portion 322 and the annular support portion 312 are fixed by fasteners 33. The hollow body 311 and the flexible component 32 form an annular groove 300.

[0092] In practical applications, a flexible layer can be provided on the inner wall of the hollow body 311, so that the inner wall, outer wall and lower end face of the quartz tube 11 are all made of flexible material, which can effectively protect the quartz tube 11.

[0093] like Figure 11 As shown, in this embodiment, the upper end of the outer sidewall of the annular body 321 has a guide surface 3211.

[0094] The guide surface 3211 makes it easier for the quartz tube 11 to be inserted into the annular groove 300.

[0095] like Figure 2 and 3 As shown, in this embodiment, the outer wall of the rotating member 31 has a first gear 313, and the driving assembly 4 includes a driving gear 41 and a driving motor 42 for driving the driving gear 41 to rotate. The driving gear 41 directly meshes with the first gear 313 or indirectly meshes with it through a transmission gear.

[0096] like Figure 2 , 11 As shown in 12 and 13, in this embodiment, the inner diameter of the annular body 321 is smaller than the inner diameter of the annular support 312. The frame 2 also has an anti-slip frame 23 that cooperates with the upper end face of the rotating component 3. The anti-slip frame 23 is used to prevent the rotating component 3 from moving upward.

[0097] The welding device for quartz products also includes a clamping and fixing component 8 and a testing component 9:

[0098] The clamping and fixing assembly 8 includes:

[0099] The hollow conical pressure head 81 is located below the flexible component 32. The outer diameter of the upper end of the hollow conical pressure head 81 is smaller than the inner diameter of the annular body 321, and the outer diameter of the lower end of the hollow conical pressure head 81 is larger than the inner diameter of the annular body 321.

[0100] The second telescopic element 82 is arranged below the hollow conical pressing head 81 and is used to drive the hollow conical pressing head 81 to move upward, so that the annular body is deformed to the side of the quartz tube 11 and the quartz tube 11 is fixed.

[0101] The test assembly 9 comprises:

[0105] After fusion, the fusion quality needs to be detected. At present, the fusion area is usually observed by artificial naked eye to judge, which is subjective. The anti-channeling frame 23, the pressing and fixing assembly 8 and the test assembly 9 can realize reliable detection. The test principle is as follows: after fusion is completed and cooled to room temperature and the connecting element 7 is removed, the lifting element 52 drives the rotating motor 51 to move upward, the second telescopic element 82 drives the hollow conical pressing head 81 to move upward, so that the annular body is deformed to the side of the quartz tube 11 and the quartz tube 11 is fixed. Because of the existence of the anti-channeling frame 23, the rotating assembly 3 will not move upward due to the upward movement of the hollow conical pressing head 81. Then the telescopic rod 911 of the third telescopic element is extended to drive the pressing element 92 to press against the lower end surface of the fused quartz disc 12 until the value of the pressure sensor 93 reaches a preset value. At this time, it can be judged by artificial whether there is crack in the fusion area. If there is no abnormality, it means that the fusion is qualified.

[0106] The application also comprises a controller for controlling the work of each action element. For example, when the value of the pressure sensor 93 reaches a preset value during testing, the telescopic rod 911 of the third telescopic element is not in telescopic state.

[0107] As shown in Figure 11 In the embodiment, the piston rod of the third telescopic element 91 has a sliding groove 9111, and the pressing element 92 has a positioning rod 921 extending into the sliding groove 9111.

[0108] As shown in Figure 2 and 6 In the embodiment, the fusion assembly 21 further comprises a second heating nozzle 212 arranged above the first heating nozzle 211. The second heating nozzle 212 is used to heat the periphery of the quartz disc 12 before the quartz disc 12 contacts the quartz tube 11.

[0109] In actual use, the telescopic element can be an electric push rod or the like.

[0110] A specific use method of the welding device in this embodiment is as follows:

[0111] See Figure 2 , the lower end of the quartz tube 11 is inserted into the annular groove 300 of the rotating assembly 3, and the quartz plate 12 is connected with the output shaft 511 of the rotating motor 51 through the connecting piece 7;

[0112] See Figure 6 , the lifting element 52 drives the rotating motor 51 and the quartz plate 12 to move downward, so that the quartz plate 12 moves downward to the second heating nozzle 212;

[0113] When the driving motor 42 works, the quartz tube 11 and the rotating assembly 3 are driven to rotate through the engagement of the driving gear 41 and the first gear 313, the rotating motor 51 drives the quartz plate 12 to rotate at the same speed as the rotating assembly 3, the welding assembly 21 works, the first heating nozzle 211 heats the upper end of the quartz tube 11 to be welded, and the second heating nozzle 212 heats the periphery of the quartz plate 12 to be welded;

[0114] As shown in Figure 9 , the second heating nozzle 212 stops working, and the lifting element 52 drives the rotating motor 51 and the quartz plate 12 to move further downward, so that the quartz plate 12 contacts the quartz tube 11;

[0115] As shown in Figure 10 , the first telescopic element 223 works, driving the movable frame 221 to approach the rotating assembly 3, so that the arc-shaped surface 2221 of the arc-shaped limiting block 222 simultaneously contacts the upper end of the quartz tube 11 and the quartz plate 12, and the outside of the welding area is pressed, so that the welding shape is well maintained;

[0116] After the welding is completed and cooled to room temperature, and the connecting piece 7 is removed, the lifting element 52 drives the rotating motor 51 to move upward;

[0117] As shown in Figure 11 and 12 , the second telescopic element 82 drives the hollow conical pressure head 81 to move upward, so that the annular body deforms toward the quartz tube 11 side, and the quartz tube 11 is fixed, and because of the existence of the anti-channeling frame 23, the rotating assembly 3 will not move upward due to the upward movement of the hollow conical pressure head 81;

[0118] As shown in Figure 13 , the telescopic rod 911 of the third telescopic element extends, driving the pressing piece 92 to press the lower end surface of the welded quartz plate 12, and stopping the action after the value of the pressure sensor 93 reaches the preset value, and observing the welding area, if there is no crack, the welding is qualified, and if there is a crack, the quartz product needs to be placed in the unqualified area for another disposal.

[0119] The above merely describes preferred embodiments of the present application, and is not intended to limit the patent protection scope of the present application, and any equivalent structural transformation, direct or indirect application in other related technical fields, are also included in the protection scope of the present application.
