Description

Technical Field

[0001] The invention relates to the technical field of quartz processing, in particular to composite quartz boat automatic welding equipment. Background Art

[0002] Quartz boat welding equipment is a high-precision equipment specially used for welding quartz boats, which is widely used in high-tech industries such as semiconductors and photovoltaics. Quartz boats are high-purity quartz products used to hold wafers, and their manufacturing requires extremely high purity and precision. Quartz boat welding equipment has the characteristics of high temperature stability and precision control. This equipment can ensure the high strength and high purity of the welding point, while effectively reducing pollution during the welding process, improving product quality and production efficiency.

[0003] When welding quartz tubes and quartz plates, the existing quartz boat welding equipment can only clamp and weld a single quartz tube and a quartz plate in sequence due to the limitations of the clamping structure and the welding module, which has low welding efficiency and increases the possibility of errors in each clamping and welding process. The errors will accumulate and affect the processing effect. At the same time, when adjusting the welding gun, since welding requires uniform flame coverage, it is necessary to set multiple sets of welding guns at the welding position. It takes a long time to adjust the position of multiple sets of welding guns. At the same time, since the angle and position of the welding gun relative to the quartz tube need to be adjusted manually, it is difficult to ensure the consistency of each welding, and the position of multiple sets of welding guns needs to be accurately adjusted to achieve uniform heating. In addition, the equipment usually has welding guns installed in a dispersed manner, and the equipment as a whole is relatively dispersed, occupies a large space, and is not compact enough. During the welding process, traditional equipment also lacks intuitive monitoring of fuel pressure. During the welding process, it is difficult for the operator to immediately detect the problem of fuel pressure. Insufficient or excessive fuel supply may cause welding quality problems or safety hazards. Summary of the invention

[0006] Preferably, the welding module includes a fixed tube, an air pipe and a welding disk, the fixed tube is fixedly installed on the clamping frame, the air pipe is arranged on the clamping frame, the air pipe is connected to one end of the fixed tube, and the other end of the fixed tube is fixedly connected to the welding disk, the welding disk is semi-annular and hollow inside, a telescopic disk is nested in the welding disk, the telescopic disk is slidably connected to the welding disk, the telescopic disk is semi-annular and hollow inside, the telescopic disk and the welding disk are sealed, and when the gas volume in the welding disk increases, the telescopic disk and the welding disk slide relative to each other; a spray gun is arranged on the telescopic disk and the welding disk.

[0007] Preferably, there are two groups of spray guns arranged on the welding disk and the angle between them is 120°. After the telescopic disk and the welding disk slide, the angle between the spray guns on the telescopic disk and the spray guns on the welding disk is 120°.

[0008] Preferably, the fixing tube is a flexible structure, and the welding plate and the processed quartz tube are coaxially arranged.

[0009] Preferably, the inner diameter of the welding plate is larger than the diameter of the processed quartz tube.

[0010] Preferably, the first pipe clamp and the second pipe clamp are both provided with clamping ends, and the clamping ends are processed into an arc shape.

[0011] Preferably, the arc diameter of the clamping end is larger than the diameter of the processed quartz tube.

[0012] Preferably, a plurality of empty grooves penetrating the clamping end are equidistantly formed on the surface of the clamping end of the second pipe clamp.

[0013] Preferably, a reset structure for driving the telescopic disk to reset is also provided between the welding disk and the telescopic disk, the reset structure adopts a heat-resistant elastic structure, one end of the reset structure is fixedly connected to the outer wall of the welding disk, and the other end of the reset structure is fixedly connected to the outer wall of the telescopic disk, the restoring force of the reset structure is equal to the fuel pressure required for the spray gun to spray the flame, when the gas pressure in the welding disk and the telescopic disk is greater than the restoring force of the reset structure, the telescopic disk extends, and when the gas pressure in the welding disk and the telescopic disk is less than the restoring force of the reset structure, the telescopic disk contracts.

[0014] (III) Beneficial effects: Compared with the prior art, the present invention provides a composite quartz boat automatic welding equipment, which has the following beneficial effects: 1. The composite quartz boat automatic welding equipment, through the coordinated use of the quartz tube fixing module and the quartz plate fixing module, when the equipment welds the quartz boat, the quartz tube and the quartz plate are respectively fixed by the quartz tube fixing module and the quartz plate fixing module, and multiple quartz tubes and quartz plates can be fixed at the same time. In one operation, multiple welding points can be welded at the same time instead of one by one, thereby shortening the welding time and improving the overall production efficiency. In addition, the simultaneous fixing and welding of multiple quartz tubes and quartz plates reduces the steps of repeated clamping, thereby reducing the cumulative errors generated during each clamping and welding process and improving the welding quality.

[0015] 2. The composite quartz boat automatic welding equipment uses a welding plate structure and a telescopic plate structure. The design of the welding plate and the welding gun makes the angle and position of the welding gun relative to the quartz tube pre-fixed. Therefore, it is only necessary to adjust the position of the welding plate so that the welding plate is coaxial with the quartz tube to complete the setting of multiple groups of welding guns at the same time. There is no need to adjust the position of the welding guns one by one, which reduces the time for setting and adjustment, reduces the complexity and technical requirements of the operation, makes the equipment easier to use, and thus improves work efficiency. At the same time, the design of the welding plate and the telescopic plate integrates multiple groups of welding guns into one structure instead of installing them separately. This design makes the overall equipment more compact, saves space, and is more convenient to use. The fixed welding gun position and angle provide a more stable welding environment and improves the quality of welding.

[0016] 3. The composite quartz boat automatic welding equipment uses a welding disc structure and a telescopic disc structure in coordination. During the welding process, fuel material is transported into the welding disc through a fixed tube. During the fuel transport process, the gas volume in the welding disc increases, thereby increasing the pressure in the welding disc. The increased pressure promotes relative sliding between the telescopic disc and the welding disc until the telescopic disc is limited and cannot slide. At this time, the spray gun on the telescopic disc and the spray gun on the welding disc are both at an angle of 120°. Then, the welding position is heated by starting the welding gun. Therefore, as long as the welding disc is filled with fuel material to make the pressure in the welding disc reach a level that can completely lift the telescopic disc and ensure the spray pressure of the welding gun, the angle between the three groups of welding guns is 120°, so the processed quartz tube can be evenly heated.

[0017] 4. The composite quartz boat automatic welding equipment uses a welding disc structure, a telescopic disc structure, and a reset structure in coordination. This structure can visually observe whether there is a problem with the fuel pressure of the spray gun. The position change of the telescopic disc can serve as a visual indication of whether the fuel pressure of the spray gun is normal. When the fuel pressure is insufficient, the telescopic disc will shrink, which allows the operator to immediately notice the pressure problem and make timely adjustments and maintenance to avoid welding quality problems caused by insufficient fuel pressure and safety hazards caused by insufficient or excessive fuel supply.

DETAILED DESCRIPTION

[0028] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0029] Example 1: Please refer to Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6The composite quartz boat automatic welding equipment comprises a base 1, on which four or more linear modules 2 are fixedly installed, and the four linear modules 2 are perpendicular to each other. The four linear modules 2 are installed perpendicular to each other to achieve precise multi-dimensional adjustment. This multi-dimensional adjustment can improve the flexibility and precision of the equipment, so that it can adapt to the welding requirements of quartz boat parts of different sizes and shapes. The four linear modules 2 are respectively equipped with a quartz tube fixed module 5 and a quartz plate fixed module 6 in sequence, and the quartz tube fixed module 5 is provided with a slider 51 in the vertical direction. The design of the slider 51 allows the height and position of the quartz tube to be flexibly adjusted in the vertical direction. This enables the equipment to adapt to quartz tubes of different lengths and diameters, ensuring the accurate position of the quartz tube during welding, thereby improving the accuracy and quality of welding. A clamping frame 52 is rotatably installed on the slider 51, and the rotatable installation of the clamping frame 52 can realize the rotation adjustment of the quartz tube to ensure that it is welded at the best angle. This design improves the flexibility and adaptability of the equipment, so that it can adapt to different welding requirements and angles, thereby improving welding efficiency and quality. The upper and lower end faces of the clamping frame 52 are both slidably equipped with a tube clamp 1 53, and the side end face of the clamping frame 52 is symmetrically slidably equipped with a tube clamp 2 54. The processed quartz tube 3 is clamped between the tube clamp 1 53 and the tube clamp 2 54. The tube clamp 1 53 and the tube clamp 2 54 ensure that the quartz tube is firmly fixed in the correct position during the welding process. Multi-point fixation can reduce the movement and vibration of the quartz tube, and ensure the stability of positioning and welding quality during the welding process. The quartz plate fixing module 6 is vertically slidably connected with a fixed plate 61, and the design of the vertical sliding connection allows the height of the quartz plate to be accurately adjusted. This design enables the equipment to adapt to quartz plates of different thicknesses and sizes, ensuring the accurate position of the quartz plate during welding. The fixed plate 61 is symmetrically provided with sliding jaws 62, and the processed quartz plate 4 is clamped on the jaws 62. The sliding jaws 62 are symmetrically provided up and down to ensure that the quartz plate is firmly fixed during the welding process. Symmetrical fixation can reduce the movement and vibration of the quartz plate, improve the stability of positioning and welding quality during welding; a welding module 56 is provided at the joint position of the processed quartz plate 4 and the processed quartz tube 3, and the welding module 56 is assembled on the clamping frame 52. This structure can achieve synchronous welding, reduce repeated operations, and improve welding efficiency and quality. At the same time, the welding module 56 is directly assembled on the clamping frame 52, which can ensure stability during welding.

[0030] See also Figure 1 , Figure 5 , Figure 6 , Figure 7 and Figure 8The welding module 56 includes a fixed pipe 561, an air pipe 562, and a welding plate 563. The fixed pipe 561 is fixedly mounted on the clamping frame 52 to ensure the stability of the position of the fixed pipe 561 and provide a stable fuel delivery channel. The stability of the position of the fixed pipe 561 helps to reduce the unevenness of the fuel supply during welding. The air pipe 562 is arranged on the clamping frame 52, and the fuel is delivered through the air pipe 562 on the clamping frame 52 to provide fuel for the welding plate 563. The centralized fuel supply system can simplify the pipeline design and reduce the complexity of the external pipeline. The air pipe 562 is connected to one end of the fixed pipe 561, and the air pipe 562 is connected to the fuel storage device. The other end of the fixed pipe 561 is fixedly connected to the welding plate 563. The fixed pipe 561 delivers fuel to the welding plate 563. This design can provide a continuous and stable fuel supply, thereby maintaining the fuel pressure in the welding plate 563 stable and improving the welding quality. The welding disc 563 is in a semi-ring shape and hollow inside, so that the welding disc 563 can be operated around the processed quartz tube, while providing enough internal space to accommodate fuel and generate gas pressure. At the same time, the internal hollow design can effectively utilize the gas pressure generated by the fuel to push the telescopic disc 564, ensuring the functionality and ease of operation of the welding disc 563. The telescopic disc 564 is nested in the welding disc 563, and the telescopic disc 564 is slidably connected to the welding disc 563, so that the telescopic disc 564 can slide freely inside the welding disc 563 to adjust the angle of the welding gun 565. The sliding connection design can automatically adjust the position of the telescopic disc 564 by fuel pressure, ensuring the automatic adjustment and stability of the welding gun angle. The telescopic disc 564 is in a semi-ring shape and hollow inside, consistent with the shape and function of the welding disc 563, while providing enough internal space to accommodate fuel. The consistent shape design ensures that the telescopic disc 564 can be completely nested in the welding disc 563, and the internal hollow design helps to maintain fuel pressure and promote the movement of the telescopic disc 564. A seal is set between the telescopic disk 564 and the welding disk 563 to prevent fuel leakage and ensure the stability of the internal gas pressure. The sealing design can improve fuel utilization efficiency, reduce fuel waste, and ensure safety and stability during welding. When the gas volume in the welding disk 563 increases, the telescopic disk 564 and the welding disk 563 slide relative to each other. This structure uses the change in gas volume to automatically adjust the working state of the welding equipment. The increase in gas volume drives the telescopic disk 564 to slide, which can achieve automatic adjustment of the position of the welding disk 563 and the welding gun. This design can reduce the steps of manual adjustment, reduce the complexity of operation, and improve the degree of automation and work efficiency of the equipment; please refer to Figure 7 and Figure 8, spray guns 565 are provided on the telescopic disk 564 and the welding disk 563. There are two groups of spray guns 565 provided on the welding disk 563 and the angle between them is 120°, which ensures that the processed quartz tube 3 can be evenly heated during the welding process. By setting two welding guns and maintaining an angle of 120°, uniform heating of the quartz tube can be achieved, preventing local overheating or uneven heating, thereby improving welding quality and consistency. At the same time, this configuration can also make the welding process more stable and reduce stress concentration and welding defects caused by uneven temperature distribution. After the telescopic disk 564 slides with the welding disk 563, the sliding direction is as follows: Figure 8 As shown by the middle arrow, the angle between the spray gun 565 on the telescopic plate 564 and the spray gun 565 on the welding plate 563 is 120°. This ensures that the spray gun 565 can maintain the best angle configuration during welding to achieve efficient and uniform heating. When the telescopic plate 564 and the welding plate 563 slide into place, the angle between the spray guns 565 is 120°, which can ensure that the heating areas of the three spray guns 565 are evenly covered during welding. This design can improve the quality and efficiency of welding and reduce welding defects caused by uneven heating. In addition, the 120° angle design can also ensure that when the fuel pressure is insufficient, the operator can promptly discover problems by observing the changes in the position of the telescopic plate 564, make adjustments and maintenance, and avoid safety hazards.

[0031] See also Figure 1 , Figure 5 and Figure 6The fixed tube 561 is a flexible structure, which can enhance the adaptability and flexibility of the equipment. The flexible structure of the fixed tube 561 allows the welding disc 563 and the spray gun 565 to move and adjust freely within a certain range. This design allows the welding disc 563 to adapt to different working environments and welding requirements more flexibly, reducing the restrictions caused by the rigid structure, thereby improving the versatility and ease of operation of the equipment. The welding disc 563 is coaxially arranged with the processed quartz tube 3. It is ensured that the positions of the welding disc 563 and the quartz tube are accurately aligned during the welding process. The coaxial setting can ensure that the spray gun 565 on the welding disc 563 can evenly surround the quartz tube for heating and welding. This design can improve the uniformity and quality of welding and reduce welding defects caused by misaligned positions. In addition, the coaxial setting can also reduce the stress concentration generated during the welding process and extend the service life of the welded joint. The inner diameter of the welding disc 563 is larger than the diameter of the processed quartz tube 3, so that the welding disc 563 has enough space to operate when covering the quartz tube. The inner diameter of the welding plate 563 is larger than the diameter of the quartz tube, providing sufficient operating space so that the welding plate 563 can smoothly cover the quartz tube and provide the best working distance for the spray gun 565. This design can improve the uniformity and quality of welding and reduce the operating difficulties and welding defects caused by insufficient space. The tube clamp 1 53 and the tube clamp 2 54 are both provided with a clamping end 55, which is processed into an arc shape, and the arc diameter of the clamping end 55 is larger than the diameter of the processed quartz tube 3. This can ensure that the quartz tube is stable and evenly stressed during the clamping process. The arc-shaped clamping end 55 can better fit the surface of the quartz tube, increase the contact area, and provide a more stable fixing force. At the same time, the arc diameter of the clamping end 55 is larger than the diameter of the quartz tube, which can avoid excessive local stress on the quartz tube during the clamping process, reduce the risk of quartz tube rupture or damage, and improve the stability and safety of clamping. The surface of the clamping end 55 of the tube clamp 2 54 is equidistantly provided with a number of empty grooves that penetrate the clamping end 55. This can improve the uniformity of the distribution of the clamping force and reduce the stress concentration generated during the clamping process. The hollow groove design allows the clamping end 55 to apply a uniform fixing force at multiple points when clamping the quartz tube, avoiding stress concentration and quartz tube cracking caused by excessive force at a single point. In addition, the hollow groove design can also increase the elasticity and adaptability of the clamping end 55, so that it can better fit and fix the quartz tube, and improve the stability and safety of the clamping.

[0032] Example 2: Please refer to Fig. 9A reset structure 566 is also provided between the welding disk 563 and the telescopic disk 564 to drive the telescopic disk 564 to reset. The reset structure 566 adopts a heat-resistant elastic structure, and uses a ceramic spring or a metal bellows. One end of the reset structure 566 is fixedly connected to the outer wall of the welding disk 563, and the other end of the reset structure 566 is fixedly connected to the outer wall of the telescopic disk 564, in order to achieve reliable control of the telescopic disk 564. When the fuel pressure in the welding disk 563 and the telescopic disk 564 changes, the reset structure 566 can respond to this change, thereby controlling the extension or contraction of the telescopic disk 564. This fixed connection method can ensure that the reset structure 566 accurately transmits force when the fuel pressure changes, and ensures the smooth movement of the telescopic disk 564. The restoring force of the reset structure 566 is equal to the fuel pressure required by the spray gun 565 to spray the flame, in order to enable the reset structure 566 to respond quickly and reset when the fuel pressure is insufficient. This design can automatically adjust the position of the telescopic disk 564 through changes in fuel pressure. When the gas pressure is greater than the restoring force, it indicates that the fuel supply is sufficient, which can push the telescopic disc 564 to extend, so that the welding torch 565 can reach the best welding angle and position. When the gas pressure is less than the restoring force, it indicates that the fuel supply is insufficient, and the reset structure 566 will shrink and drive the telescopic disc 564 to reset. This situation can promptly remind the operator of insufficient fuel pressure, so that adjustments and maintenance can be made to avoid welding quality problems and safety hazards.

[0033] Working principle: When the device is used to weld the quartz tube and quartz plate of the quartz boat, the quartz tube and the quartz plate are fixed respectively by the quartz tube fixing module 5 and the quartz plate fixing module 6. When fixing the quartz tube, the quartz tube fixing module 5 first adjusts the overall position of the quartz tube fixing module 5 through the linear module 2, and then adjusts the height and angle of the clamping frame 52 through the slider 51, and clamps the processed quartz tube 3 with the tube clamp 1 53 and the tube clamp 2 54. Four processed quartz tubes 3 can be fixed in sequence according to the above process, thereby realizing the fixed clamping of multiple quartz tubes. In the above process, the quartz fixing module is adjusted at the same time, the overall position of the quartz plate fixing module 6 is adjusted by the linear module 2, and then the height and angle of the fixing plate 61 are adjusted, and finally the processed quartz plate 4 is clamped and fixed by the clamping jaws 62, and the processed quartz plate 4 on the other side is also set as above. After the processed quartz tube 3 and the processed quartz plate 4 are completely fixed, the welding module 56 is adjusted to be coaxial with the processed quartz tube 3 to weld the connecting position of the processed quartz tube 3 and the processed quartz plate 4. This structure can fix and weld multiple processed quartz tubes 3 and processed quartz plates 4 at the same time, thereby improving the welding efficiency of the equipment; this method of welding multiple processed quartz tubes 3 at the same time can effectively avoid the error caused by the need to fix and weld a single quartz tube separately during traditional quartz boat welding, while the traditional quartz boat welding method can only fix a single processed quartz tube 3 and a processed quartz plate 4 in turn and can only perform a single welding, which increases the error accumulation in the operation.

[0034] When welding the quartz boat, by adjusting the position of the welding disk 563, it is only necessary to set the welding disk 563 coaxially with the processed quartz tube 3, and transport the fuel material to the welding disk 563 through the fixed tube 561. In the process of transporting the fuel, the volume of the gas in the welding disk 563 will increase, thereby increasing the pressure in the welding disk 563. The increase in pressure will promote the relative sliding between the telescopic disk 564 and the welding disk 563 until the telescopic disk 564 is limited and cannot slide. At this time, the angle between the spray gun 565 on the telescopic disk 564 and the spray gun 565 on the welding disk 563 is 120°, and then the welding gun is started to heat the welding position. When setting up this structure, it is only necessary to move the welding disk 563 through the fixed tube 561 so that the welding disk 563 and the processed quartz tube 3 are coaxial to complete the setting of multiple groups of welding guns. Moreover, since the welding guns are installed on the welding disk 563 and the telescopic disk 564, it saves more space than the traditional structure. At the same time, since it is only necessary to move and align the welding disk 563, it can reduce the adjustment time and improve the work efficiency. During the welding process, as long as the fuel material is filled into the welding disk 563 so that the pressure in the welding disk 563 reaches a level that can completely lift the telescopic disk 564 and ensure the spray pressure of the welding gun, the angle between the three groups of welding guns is 120°, so the processed quartz tube 3 can be evenly heated.

[0035] When the fuel pressure of the spray gun 565 is insufficient, the pressure inside the welding disk 563 and the telescopic disk 564 will decrease accordingly. Since the restoring force of the reset structure 566 is equal to the fuel pressure required for the spray gun 565 to spray the flame, when the pressure inside the telescopic nozzle is less than the fuel pressure required for the spray gun 565 to spray the flame, the reset structure 566 will contract and pull the telescopic disk 564 to reset. This allows the operator to immediately detect the pressure problem and make timely adjustments and maintenance to avoid welding quality problems caused by insufficient fuel pressure and safety hazards caused by insufficient or excessive fuel supply.
