Description

Technical Field

[0001] This invention relates to the field of quartz processing technology, and in particular to a processing equipment and method for quartz composite structures. Background Technology

[0002] Sandwich fins are used in advanced chip manufacturing processes. Quartz composite structures (e.g., transparent quartz tubes and opaque quartz rods) are components used on sandwich fins. They are usually machined manually, which mainly depends on the experience level of workers and requires a high level of skill. Manual machining is inefficient and has a low product yield.

[0003] Therefore, it is necessary to propose a processing equipment and method for quartz composite structures to solve the above problems. Summary of the Invention

[0018] The first rotation drive mechanism includes a first motor, a first drive wheel, a first driven ring, and a first transmission belt. The first motor is mounted on the first base and driven by the first drive wheel. The end of the first driven ring is mounted and connected to the first three-jaw hollow chuck. The first driven ring extends into the first base through the first through hole and is fitted onto the first perforated plate so that the first driven ring can rotate around the first perforated plate. The first transmission belt is wound around the first drive wheel and the first driven ring.

[0019] In one possible embodiment, the second base is hollow inside, and a second through hole is provided transversely through the middle of the second base, and a second perforated plate is formed around the second through hole;

[0020] The second mounting clip is a second three-jaw hollow chuck with a second jaw hole. The second three-jaw hollow chuck is rotatably mounted on the second base, and the second jaw hole communicates with the second through hole.

[0021] The inner quartz material is inserted into the second claw hole and the second perforation, and extends out of the second base.

[0022] In one possible embodiment, the second base has a second annular hole on the side near the first base, and the second annular hole is arranged around the hole wall of the second through hole;

[0023] The second rotation drive mechanism includes a second motor, a second driving wheel, a second driven ring, and a second transmission belt. The second motor is mounted on the second base and driven by the second driving wheel. The end of the second driven ring is mounted and connected to the second three-jaw hollow chuck. The second driven ring extends into the first base through the first through hole and is fitted onto the first perforated plate so that the first driven ring can rotate around the first perforated plate. The second transmission belt is wound around the second driving wheel and the second driven ring.

[0024] In one possible embodiment, a movable end is formed on the transverse drive mechanism, and the movable end is position-adjustable along the extension direction of the worktable;

[0025] The processing equipment also includes a height adjustment mechanism vertically mounted on the moving end, the height of which is telescopically adjustable, and the welding torch is mounted at the top of the height adjustment mechanism.

[0026] In one possible embodiment, the processing equipment further includes a longitudinal drive mechanism that is arranged in the longitudinal direction and whose length is telescopically adjustable, the longitudinal drive mechanism being mounted between the moving end and the bottom end of the height adjustment mechanism.

[0027] In one possible embodiment, the processing equipment further includes a first rotary cylinder horizontally disposed above the moving end, the first rotary cylinder having a first rotating disk drivenly connected to the welding torch, and the first rotary cylinder being used to drive the welding torch to rotate in the horizontal direction.

[0028] In one possible embodiment, the processing equipment further includes a vertically arranged second rotary cylinder, the first rotary disk of the first rotary cylinder is drivenly connected to the bottom end of the second rotary cylinder, the second rotary disk of the second rotary cylinder is drivenly connected to the welding torch, and the second rotary cylinder is used to drive the welding torch to rotate in the vertical direction.

[0029] The present invention also provides a method for processing a quartz composite structure, using the processing equipment for quartz composite structures as described in any of the above embodiments, the processing method comprising the following steps:

[0030] The outer quartz tube is held by the first mounting clip, and the inner quartz material is held by the second mounting clip. The inner quartz material is then inserted into the outer quartz tube so that the outer quartz tube and the inner quartz material partially overlap.

[0031] The outer quartz tube and the inner quartz material are initially welded together to form a sealed space between them.

[0032] Connect the vacuum pumping device to the end of the outer quartz tube that is away from the inner quartz material;

[0033] The first and second rotation drive mechanisms are activated, causing them to drive the first and second mounting clamps to rotate synchronously in the same direction, so that the outer quartz tube and the inner quartz material rotate synchronously in the same direction. At the same time, the lateral drive mechanism and the vacuum pumping device are activated. The vacuum pumping device evacuates the outer quartz tube, and the lateral drive mechanism drives the welding torch to move along the extension direction of the worktable to heat the overlapping part of the outer quartz tube and the inner quartz material with flame to form a quartz composite structure.

[0034] The beneficial effects of this invention are as follows: When the outer quartz tube and the inner quartz material are composited, the first and second rotational drive mechanisms drive the first and second mounting clamps to rotate synchronously in the same direction, so that the outer quartz tube and the inner quartz material rotate synchronously in the same direction. A vacuum is drawn from the outer quartz tube by the vacuum pumping device, and the welding torch is driven to move along the extension direction of the worktable, i.e., along the extension direction of the outer quartz tube, by the transverse drive mechanism. The overlapping portion of the outer quartz tube and the inner quartz material is heated by flame, causing the outer quartz tube and the inner quartz material to combine and form a quartz composite structure. This invention achieves automated composite processing of the outer quartz tube and the inner quartz material, eliminating the need for manual labor, improving processing efficiency and accuracy, and thus increasing product yield.

[0061] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below. Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0062] To address the problems existing in the above-mentioned technologies, embodiments of the present invention provide a processing equipment for quartz composite structures, see [link to relevant documentation]. Figure 1The processing equipment includes: a worktable 110, a first base 111, a second base 112, a first mounting clamp 120, a first rotation drive mechanism 130, a second mounting clamp 140, a second rotation drive mechanism 150, a transverse drive mechanism 161, a welding torch 170, and a vacuum pumping device 180. The first base 111 and the second base 112 are mounted on the worktable 110 and arranged opposite to each other. The first mounting clamp 120 is rotatably mounted on the first base 111 and is used to clamp the outer quartz tube 200. The first rotation drive mechanism 130 is drivenly connected to the first mounting clamp 120 and is used to drive the first mounting clamp 120 to rotate. The second mounting clip 140 is rotatably mounted on the second base 112 and is used to hold the inner quartz material 300. The first mounting clip 120 and the second mounting clip 140 are arranged opposite to each other so that the inner quartz material 300 can be inserted into the outer quartz tube 200. The inner quartz material 300 is an inner quartz tube or an inner quartz rod. The second rotation drive mechanism 150 is drivenly connected to the second mounting clip 140 and is used to drive the second mounting clip 140 to rotate. The transverse drive mechanism 161 is mounted on the worktable 110 and is drivenly connected to the welding torch 170 and is used to drive the welding torch 170 to move along the extension direction of the worktable 110. The welding torch 170 is arranged corresponding to the outer quartz tube 200 and is used to flame-heat the overlapping part of the outer quartz tube 200 and the inner quartz material 300 to form a quartz composite structure. The vacuum pumping device 180 is connected to the end of the outer quartz tube 200 away from the inner quartz material 300 and is used to evacuate the outer quartz tube 200 during processing.

[0063] Specifically, the extension direction of the workbench 110 is set to the horizontal direction. After the outer quartz tube 200 and the inner quartz material 300 are clamped, they are arranged horizontally. Therefore, the horizontal drive mechanism 161 drives the welding torch 170 to move in the horizontal direction. That is, the welding torch 170 can move along the extension direction of the outer quartz tube 200 and perform flame heating on the overlapping part of the outer quartz tube 200 and the inner quartz material 300.

[0064] In this embodiment, the present invention proposes an automated processing device. The rotation speeds of the outer quartz tube 200 and the inner quartz material 300 can be precisely controlled by the first rotation drive mechanism 130 and the second rotation drive mechanism 150, ensuring that the outer quartz tube 200 and the inner quartz material 300 always rotate in the same direction and synchronously during processing. This ensures that the welding torch 170 can uniformly heat the outer wall of the outer quartz tube 200. The moving speed of the welding torch 170 can be precisely controlled by the transverse drive mechanism 161. The welding torch 170 moves from the overlapping portion of the outer quartz tube 200 and the inner quartz material 300. One end is gradually moved to the other end to gradually heat the overlapping part of the outer quartz tube 200 and the inner quartz material 300 with flame, making the welding more uniform. Vacuuming allows the heated and softened outer quartz tube 200 to shrink inward to fit onto the inner quartz material 300 (the inner quartz material 300 is not softened or deformed), ensuring that the outer quartz tube 200 and the inner quartz material 300 are fully and uniformly fused, improving processing accuracy. Automated processing avoids the instability factors caused by manual processing, improves the molding quality of quartz composite structures, thereby improving product yield and processing efficiency.

[0065] In a preferred embodiment, see [link to previous document]. Figure 2 The first base 111 is hollow inside, and a first through hole 1111 is provided transversely through the middle of the first base 111, forming a first perforated plate 1113 surrounding the first through hole 1111. The first mounting clamp 120 is a first three-jaw hollow chuck with a first jaw hole 121. The first three-jaw hollow chuck is rotatably mounted on the first base 111, and the first jaw hole 121 communicates with the first through hole 1111. The outer quartz tube 200 passes through the first jaw hole 121 and the first through hole 1111, and extends out of the first base 111.

[0066] In this embodiment, a first three-jaw hollow chuck is used, and a first through hole 1111 is provided on the first base 111 so that the outer quartz tube 200 can be installed through the first three-jaw hollow chuck and the first base 111. This facilitates the installation and connection of the vacuum pumping device 180 to the end of the outer quartz tube 200 away from the inner quartz material 300. In addition, it is convenient to clamp a longer outer quartz tube 200 without the need for an additional cutting step. When cutting the quartz composite structure after composite processing, the outer quartz tube 200 can be cut together, reducing the number of cutting steps.

[0067] In one specific embodiment, see Figure 2 The first base 111 has a first annular hole 1112 on one side near the second base 112, and the first annular hole 1112 surrounds the first perforated plate 1113. (See also...) Figure 2 and Figure 3The first rotation drive mechanism 130 includes a first motor 131, a first drive wheel 132, a first driven ring 133, and a first transmission belt 134. The first motor 131 is mounted on the first base 111 and is driven by the first drive wheel 132. The end of the first driven ring 133 is connected to a first three-jaw hollow chuck. The first driven ring 133 extends into the first base 111 through a first through hole 1111 and is fitted onto a first perforated plate 1113 so that the first driven ring 133 can rotate around the first perforated plate 1113. The first transmission belt 134 is wound around the first drive wheel 132 and the first driven ring 133. Preferably, see [reference needed]. Figure 4 The first three-jaw hollow chuck has three first jaws 122 on one side, see [reference]. Figure 2 The first driven ring 133 is connected to the side of the first three-jaw hollow chuck away from the first jaw 122.

[0068] For a better option, see [link to previous section]. Figure 2 and Figure 3 The center line of the first annular hole 1112 is consistent with the center line of the first three-jaw hollow chuck. The first annular hole 1112 is set along the edge of the first through hole 1111. The first driven ring 133 can rotate around the first hole plate 1113 under the drive of the first motor 131. The first driving wheel 132, the first driven ring 133 and the first transmission belt 134 are located in the first base 111.

[0069] Specifically, the first driven ring 133 is provided with a first limiting member 1331, which is blocked on the inner wall of the first base 111 to prevent the first driven ring 133 from coming out of the first ring hole 1112.

[0070] In this embodiment, the first motor 131 drives the first drive wheel 132 to rotate. Under the transmission action of the first transmission belt 134, the first driven ring 133 will rotate together with the first three-jaw hollow chuck, thereby enabling precise control of the rotation speed of the first three-jaw hollow chuck.

[0071] In a preferred embodiment, see [link to previous document]. Figure 5 The second base 112 is hollow inside, and a second through hole 1121 is provided transversely through the middle of the second base 112, forming a second perforated plate 1123 surrounding the second through hole 1121. The second mounting clamp 140 is a second three-jaw hollow chuck with a second jaw hole 141. The second three-jaw hollow chuck is rotatably mounted on the second base 112, and the second jaw hole 141 communicates with the second through hole 1121. The inner layer of quartz material 300 passes through the second jaw hole 141 and the second through hole 1121 and extends out of the second base 112.

[0072] In this embodiment, a second three-jaw hollow chuck is used, and a second through hole 1121 is provided on the second base 112 so that the inner quartz material 300 can be installed through the second three-jaw hollow chuck and the second base 112. This facilitates clamping the longer inner quartz material 300 without the need for additional cutting of the inner quartz material 300. When cutting the quartz composite structure after composite processing, the material is cut together, reducing the number of cutting steps.

[0073] In one specific embodiment, see Figure 6 The second base 112 has a second annular hole 1122 on the side near the first base 111, and the second annular hole 1122 surrounds the second perforated plate 1123. (See also...) Figure 5 and Figure 6 The second rotation drive mechanism 150 includes a second motor 151, a second drive wheel 152, a second driven ring 153, and a second transmission belt 154. The second motor 151 is mounted on the second base 112 and is driven by the second drive wheel 152. The second driven ring 153 is mounted on and connected to the second three-jaw hollow chuck. The second driven ring 153 extends into the second base 112 through the second through hole 1121 and is fitted onto the second perforated plate 1123 so that the second driven ring 153 can rotate around the second perforated plate 1123. The second transmission belt 154 is wound around the second drive wheel 152 and the second driven ring 153. Preferably, the second three-jaw hollow chuck has three second jaws 142 on one side, and the second driven ring 153 is connected to the side of the second three-jaw hollow chuck away from the second jaws 142.

[0074] For a better option, see [link to previous section]. Figure 5 and Figure 6 The center line of the second annular hole 1122 is consistent with the center line of the second three-jaw hollow chuck. The second annular hole 1122 is set along the edge of the second through hole 1121. Under the drive of the second motor 151, the second driven ring 153 can rotate around the second hole plate 1123. The second driving wheel 152, the second driven ring 153 and the second transmission belt 154 are located in the second base 112.

[0075] Specifically, the second driven ring 153 is provided with a second limiting member 1531, which is blocked on the inner wall of the second base 112 to prevent the second driven ring 153 from coming out of the second ring hole 1122.

[0076] In this embodiment, the second motor 151 drives the second drive wheel 152 to rotate. Under the transmission action of the second transmission belt 154, the second driven ring 153 will rotate together with the second three-jaw hollow chuck, thereby enabling precise control of the rotation speed of the second three-jaw hollow chuck.

[0077] In a preferred embodiment, see [link to previous document]. Figure 1The transverse drive mechanism 161 has a movable end 1611, which can be adjusted in position along the extension direction of the worktable 110. The processing equipment also includes a height adjustment mechanism 162 vertically mounted on the movable end 1611. The height of the height adjustment mechanism 162 is telescopically adjustable, and the welding torch 170 is mounted on a mounting base 1623 at the top of the height adjustment mechanism 162. Preferably, the transverse drive mechanism 161 is located on the side of the worktable 110. The transverse drive mechanism 161 can be a first cylinder or a first electric telescopic rod, and its orientation is consistent with the extension direction of the worktable 110. The height adjustment mechanism 162 can be a second cylinder or a second electric telescopic rod.

[0078] In a preferred embodiment, see [link to previous document]. Figure 1 and Figure 7 The processing equipment also includes a longitudinal drive mechanism 163, which is arranged in the longitudinal direction and has an adjustable length. The longitudinal drive mechanism 163 is installed and connected between the moving end 1611 and the bottom end of the height adjustment mechanism 162. Preferably, the longitudinal drive mechanism 163 can be a third cylinder or a third electric telescopic rod. In this embodiment, the width direction of the worktable 110 is set as the longitudinal direction.

[0079] In a preferred embodiment, see [link to previous document]. Figure 1 , Figure 7 as well as Figure 8 A guide groove 113 is provided on the side of the worktable 110 near the transverse drive mechanism 161, and the direction of the guide groove 113 is consistent with the extension direction of the worktable 110. A support member 1612 is provided on the moving end 1611 of the transverse drive mechanism 161, and a guide block 1613 is provided on the support member 1612 corresponding to the guide groove 113. The guide block 1613 is adapted to the guide groove 113 and slides in the guide groove 113 to ensure the smooth movement of the support member 1612. One end of the longitudinal drive mechanism 163 is located at the top of the support member 1612, and the other end is located on the side wall at the bottom of the height adjustment mechanism 162. The bottom of the height adjustment mechanism 162 is provided with a groove 1621, in which a ball bearing 1622 is embedded. The ball bearing 1622 partially extends out of the groove 1621 and can rotate within the groove 1621 to reduce the friction between the height adjustment mechanism 162 and the machine tool components, thereby making the height adjustment mechanism 162 move more smoothly. Preferably, the support member 1612 can be plate-shaped, column-shaped, or rod-shaped.

[0080] This invention adjusts the length of the lateral drive mechanism 161 by telescopically adjusting it, allowing the support member 1612 to slide along the length of the guide groove 113. This, in turn, moves the longitudinal drive mechanism 163 and the height adjustment mechanism 162 laterally, thereby adjusting the lateral position of the welding torch 170. Similarly, adjusting the length of the longitudinal drive mechanism 163 allows the height adjustment mechanism 162 to move longitudinally, adjusting the longitudinal position of the welding torch 170. Finally, adjusting the height of the height adjustment mechanism 162 allows for vertical position adjustment of the welding torch 170. Therefore, the lateral drive mechanism 161, longitudinal drive mechanism 163, and height adjustment mechanism 162 enable precise control of the welding torch 170's movement position in three-dimensional space (lateral, longitudinal, and vertical directions).

[0081] In a preferred embodiment, see [link to previous document]. Figure 1 and Figure 7 The processing equipment also includes a first rotary cylinder 191 horizontally mounted on the moving end 1611. The first rotary disk of the first rotary cylinder 191 is drivenly connected to the welding torch 170, and the first rotary cylinder 191 drives the welding torch 170 to rotate horizontally. Preferably, the first rotary cylinder 191 is horizontally mounted on the top of the height adjustment mechanism 162. The top of the height adjustment mechanism 162 is provided with a mounting base 1623, and the first rotary cylinder 191 is horizontally mounted on the mounting base 1623.

[0082] In a preferred embodiment, see [link to previous document]. Figure 1 and Figure 7 The processing equipment also includes a second rotary cylinder 192 arranged vertically. The first rotating disk of the first rotary cylinder 191 is driven to the bottom end of the second rotary cylinder 192. The second rotating disk of the second rotary cylinder 192 is driven to the welding torch 170. The second rotary cylinder 192 is used to drive the welding torch 170 to rotate in the vertical direction.

[0083] This invention uses a first rotary cylinder 191 to drive a second rotary cylinder 192 to rotate, causing the welding torch 170 to rotate around the center line (i.e., the vertical line) of the first rotating disk, meaning the welding torch 170 rotates horizontally. The second rotary cylinder 192 drives the welding torch 170 to rotate around the center line (i.e., the horizontal line) of the second rotating disk, meaning the welding torch 170 rotates vertically. Therefore, the first rotary cylinder 191 and the second rotary cylinder 192 achieve posture adjustment of the welding torch 170 in three-dimensional space, allowing for flexible and precise control of the welding torch 170's setting angle so that the nozzle of the welding torch 170 can be aligned with the outer quartz tube 200.

[0084] In one specific embodiment, see Figure 1 and Figure 7The second rotary cylinder 192 has a second rotary disk drive connected to a fixing member 1921. A clamp 1922 is provided at the end of the fixing member 1921 away from the second rotary disk, and the welding torch 170 is installed inside the clamp 1922. Preferably, the fixing member 1921 can be plate-shaped, column-shaped, or rod-shaped. By providing the fixing member 1921, collisions are prevented from occurring during the rotation of the welding torch 170.

[0085] In a preferred embodiment, see [link to previous document]. Figure 1 The outer quartz tube 200, at the end furthest from the inner quartz material 300, is fitted with a sealing plug 210. The processing equipment also includes a support 184 positioned near the end of the outer quartz tube 200 furthest from the inner quartz material 300, with a rotary joint 185 at its top. The vacuum pumping device 180 includes a first suction pipe 181, a second suction pipe 182, and a pump 183. One end of the first suction pipe 181 passes through the sealing plug 210 to communicate with the outer quartz tube 200, and the other end is connected to the inlet of the rotary joint 185. One end of the second suction pipe 182 is connected to the outlet of the rotary joint 185, and the other end is connected to the pump 183. In this embodiment, by providing the rotary joint 185, the first suction pipe 181 can rotate together with the outer quartz tube 200, avoiding the problem of pipe tangling.

[0086] In one specific embodiment, the processing equipment also includes a control console connected to the first rotary drive mechanism 130, the second rotary drive mechanism 150, the transverse drive mechanism 161, the height adjustment mechanism 162, the longitudinal drive mechanism 163, the vacuum pumping device 180, the first rotary cylinder 191, and the second rotary cylinder 192.

[0087] In addition, the present invention also provides a method for processing quartz composite structures, using the processing equipment for quartz composite structures as described in any of the above embodiments, see [link to documentation]. Figure 1 The processing method includes the following steps:

[0088] The outer quartz tube 200 is held by a first mounting clip 120, and the inner quartz material 300 is held by a second mounting clip 140. The inner quartz material 300 is then inserted into the outer quartz tube 200, such that the outer quartz tube 200 and the inner quartz material 300 partially overlap. Preferably, the gap between the outer quartz tube 200 and the inner quartz material 300 is 0.5mm-1mm. The outer quartz tube 200 and the inner quartz material 300 can be made of transparent or opaque materials.

[0089] The outer quartz tube 200 and the inner quartz material 300 are initially welded to form a sealed space between them. Specifically, the inner quartz material 300 has a first end located inside the outer quartz tube 200 and a second end located outside the outer quartz tube 200. A welding torch 170 is used to heat the first end of the inner quartz material 300 and a localized area of ​​the outer quartz tube 200 outside the first end, softening the localized area (while the inner quartz material 300 remains undeformed). A graphite pen is then used to spot weld at intervals on the softened localized area, for example, selecting three points at intervals along the circumferential direction. This spot welding fixes the first end of the inner quartz material 300 to the outer quartz tube 200. The spot welding serves two purposes: end fixing and creating a vacuum between the inner quartz material 300 and the outer quartz tube 200. Using a welding torch 170, heat the end of the outer quartz tube 200 near the second base 112 to weld it to the inner quartz material 300. This involves thermally fusing the end of the outer quartz tube 200 near the second base 112 onto the inner quartz material 300, creating a sealed space between them. If the inner quartz material 300 is an inner quartz tube, the second end of the inner quartz tube also needs to be sealed.

[0090] Connect the vacuum pumping device 180 to the end of the outer quartz tube 200 that is away from the inner quartz material 300.

[0091] The first rotation drive mechanism 130 and the second rotation drive mechanism 150 are activated, causing the first rotation drive mechanism 130 and the second rotation drive mechanism 150 to drive the first mounting clamp 120 and the second mounting clamp 140 to rotate synchronously in the same direction, so that the outer quartz tube 200 and the inner quartz material 300 rotate synchronously in the same direction. At the same time, the transverse drive mechanism 161 and the vacuum pumping device 180 are activated. The vacuum pumping device 180 evacuates the outer quartz tube 200. The transverse drive mechanism 161 drives the welding torch 170 to move along the extension direction of the worktable 110 to heat the overlapping part of the outer quartz tube 200 and the inner quartz material 300 with flame to form a quartz composite structure. The quartz composite structure is a two-layer structure.

[0092] In one specific embodiment, before clamping the outer quartz tube 200 with the first mounting clip 120 and clamping the inner quartz material 300 with the second mounting clip 140, the method further includes:

[0093] Flame polishing is performed on the outer quartz tube 200 and the concentricity of the outer quartz tube 200 is corrected; flame polishing is performed on the inner quartz material 300 and the concentricity of the inner quartz material 300 is corrected.

[0094] In one specific embodiment, spot welding is performed on both ends of the overlapping portion of the outer quartz tube 200 and the inner quartz material 300, including:

[0095] When spot welding is performed, spot welding is performed at at least two points at both ends of the overlapping part of the outer quartz tube 200 and the inner quartz material 300, and the at least two points at each end are distributed at intervals in the circumferential direction of the outer quartz tube 200.

[0096] In one specific embodiment, the distance between the starting heating position of the welding torch 170 on the outer quartz tube 200 and the adjacent spot welding position is 20mm-30mm.

[0097] In one specific embodiment, after the overlapping portion of the outer quartz tube 200 and the inner quartz material 300 is heated with a flame to form a quartz composite structure, the method further includes: cutting the quartz composite structure to remove the area fixed by spot welding.

[0098] This invention achieves the processing of quartz composite structures through automated processing equipment. Compared with existing manual machining methods, which require a high level of worker experience, have low processing efficiency, and unstable product yield, this invention reduces reliance on worker experience, improves processing efficiency, and ensures product quality stability through automated equipment. The outer quartz tube 200 and the inner quartz material 300 are clamped by a first mounting clamp 120 and a second mounting clamp 140, respectively, and the outer quartz tube 200 and the inner quartz material 300 are rotated synchronously in the same direction using a first rotation drive mechanism 130 and a second rotation drive mechanism 150. This synchronous rotation ensures uniform and sufficient welding of the inner quartz material 300 and the outer quartz tube 200, improving the composite molding quality of the quartz composite structure. A vacuum pump 180 evacuates the outer quartz tube 200. During flame heating, the vacuum pump 180 reduces the influence of air on flame heating, making heating more uniform and stable, thereby improving the product yield. By spot welding the two ends of the overlapping portion of the outer quartz tube 200 and the inner quartz material 300, the outer quartz tube 200 and the inner quartz material 300 can be effectively fixed, avoiding misalignment or loosening during processing, thus further improving product quality and yield. In summary, this invention, through automated processing equipment, synchronous rotation in the same direction, vacuum pumping device 180, and spot welding, solves the problems of low efficiency and unstable product yield in existing manual machining processes, improving processing efficiency, reducing reliance on worker experience, and increasing product yield.

[0099] When the welding torch 170 heats the outer quartz tube 200, the outer quartz tube 200 softens due to heat and deforms under its own weight, resulting in an uneven surface on the outer surface of the formed quartz composite structure. To solve this problem, the present invention provides a correction mechanism 40, which moves with the mounting base 1623 and the welding torch 170. This mechanism can correct the outer surface of the formed quartz composite structure after processing by the welding torch 170, ensuring that the formed quartz composite structure is free from unevenness.

[0100] Specifically, such as Figure 9 As shown, the correction mechanism 40 includes a correction body 401, a guide part 402, and a fixing rod 403. The correction body 401 (which can be understood as a tubular structure and is made of metal) is sleeved on the outer side of the inner layer of quartz material 300 with a smaller diameter. The left end of the correction body 401 is connected to the guide part 402 (which can be understood as a trumpet-shaped tubular structure, and the left end opening of the trumpet-shaped tubular structure is larger than the right end opening). The outer side wall of the correction body 401 is provided with a fixing rod 403, which is L-shaped. The end of the fixing rod 403 away from the correction body 401 is provided with a vertically arranged connecting plate 404. The connecting plate 404 is detachably installed on the side of the mounting base 1623 by fasteners (after adjusting the height adjustment mechanism 162 and ensuring that the welding torch 170 is at a suitable height, the correction mechanism 40 is installed, that is, the connecting plate 404 is installed on the mounting base 1623). Preferably, the inner diameter of the left end opening of the guide portion 402 is larger than the outer diameter of the outer quartz tube 200, the inner diameter of the right end opening of the guide portion 402 (i.e. the inner diameter of the correction body 401) is between the outer diameter of the outer quartz tube 200 and the outer diameter of the inner quartz material 300, and the inner diameter of the correction body 401 is equal to the designed outer diameter of the quartz composite structure.

[0101] During operation, initially the guide part 402 and the correction body 401 are fitted onto the right end of the inner quartz material 300. As the mounting base 1623 moves to the left with the welding torch 170, the fixing rod 403 also moves the correction body 401 and the guide part 402 to the left. The guide part 402 and the correction body 401 are then fitted onto the softened outer quartz tube 200, pressing the heated outer quartz tube 200 and the inner quartz material 300 together. Throughout the movement, because the diameter of the correction body 401 is consistent, the dimensions of the formed quartz composite structure are guaranteed to be consistent. Simultaneously, during the repair... Under the action of the inner wall of the main body 401, the outer surface of the formed quartz composite structure can be corrected, making the outer surface of the formed quartz composite structure smooth and free from unevenness. Moreover, the correcting body 401 is made of metal, which has good thermal conductivity. As the correcting body 401 moves, the temperature on the left side of the part of the formed quartz composite structure in contact with the correcting body 401 will be higher than that on the right side. Therefore, as the correcting body 401 moves to the left, the left side of the correcting body 401 is used for correction, while the right side is used for cooling and shaping, maintaining the smooth state after correction.

[0102] To make the shaping process more efficient, the present invention also adds a shaping mechanism 50, such as... Figure 10 As shown, the shaping mechanism 50 includes a ring-shaped cooling fan 501 and several air outlets 503 connected to the outlet end of the cooling fan 501, arranged in a ring. The left end of the cooling fan 501 is connected to the right end of the correction body 401 via a bearing 502. During operation, the cooling fan 501 blows cool air through the air outlets 503 onto the corrected quartz composite structure, accelerating cooling efficiency and thus improving shaping efficiency. The cooling fan 501 is a miniature fan.

[0103] To ensure uniform cooling of the molded quartz composite structure, the shaping mechanism 50 in this invention further includes a first engaging member 504, a second engaging member 505, and a driving member 506, as shown below. Figure 10 As shown, the first meshing member 504 (which can be understood as the first gear) is fixedly sleeved on the outside of the cooling fan 501. The first meshing member 504 meshes with the second meshing member 505 (which can be understood as the second gear). The second meshing member 505 is connected to the drive end of the drive member 506 (which can be understood as the drive motor). The drive member 506 is fixedly mounted on the correction body 401. During operation, the operation of the drive member 506 will cause the cooling fan 501 to rotate through the second meshing member 505 and the first meshing member 504. The rotation of the cooling fan 501 will uniformly heat the molded quartz composite structure through the air outlet 503, thereby improving the quality of the molded product.

[0104] Due to the presence of suspended particulate dust in the environment, it adheres to the surface of the molded quartz composite structure during the heating process, resulting in an uneven surface after molding. To address this issue, the present invention also includes a cleaning mechanism 60. Figure 11 As shown. The cleaning mechanism 60 includes a cleaning plate 601 disposed within the cooling fan 501, and a connecting rod 602 connected to the cleaning plate 601. The connecting rod 602 is movably inserted into the cooling fan 501, and a return spring 603 is wound around the outside of the connecting rod 602. The two ends of the return spring 603 are respectively fixedly connected to the side wall of the connecting rod 602 and the outer side wall of the cooling fan 501. During operation, the rotation of the cooling fan 501 will cause the cleaning plate 601 to rotate, and the rotation of the cleaning plate 601 will sweep away the particulate dust adhering to the surface of the molded quartz composite structure. In order to make the device applicable to molded products of different thicknesses, the cleaning plate 601 can move radially in the cooling fan 501 under the elastic extension and contraction of the return spring 603. At the same time, the radial movement of the cleaning plate 601 can also prevent the cleaning plate 601 from getting stuck when there is dust that is difficult to clean.

[0105] Of course, during the process of correcting the main body 401 moving to the left, it also has the function of cleaning away particulate dust on the surface of the molded product.
