Description

Technical Field

[0001] The invention relates to the technical field of welding, in particular to a semi-automatic quartz boat rapid welding device. Background Art

[0002] The quartz boat welding device is a technical device for the production and processing of quartz boat products, aiming to improve welding efficiency and accuracy.

[0003] However, there are still some problems with the existing quartz boat welding device: first, the welding device requires the operator to place the side panels and the slot rods in the welding station in sequence. Although the side panels have a limit device to ensure the accuracy of their placement, the slot rods do not have a similar limit design. The slot rods are simply placed on the station and lack effective positioning measures, thereby failing to ensure that the slot rods are always in the middle of the device.

[0004] The existing technology usually relies on manual position adjustment, but due to the complexity of the operation and human errors, it is impossible to ensure that the slot rods are completely aligned every time, resulting in a phenomenon of empty welds between a part of the slot rods and the side panels during the welding process. Specifically, the contact surfaces of the slot rods and the side panels cannot be completely matched during welding, resulting in insufficient welding connection in local areas, forming empty welds. This phenomenon directly leads to insufficient strength of the welded structure, and the stability and durability of the welded parts are weakened.

[0005] Secondly, modern welding equipment relies on high-precision energy control to ensure the consistency and strength of welds. When the slot rod deviates from its designed position, the welding energy cannot be fully transferred to the area that needs to be welded, resulting in insufficient welds or substandard weld strength. This not only reduces the physical properties of the welded parts, but also increases the demand for secondary processing, slows down production progress, and further exacerbates the increase in production costs.

[0006] Secondly, in addition to the above-mentioned slot rod positioning problem, the existing quartz boat welding device has a significant bottleneck in practical application, namely the cooling process after welding. After welding is completed, the quartz boat needs to be cooled for a certain period of time before unloading. This process not only prolongs the entire production cycle, but also causes waste of resources and energy.

[0007] The prior art uses fan structures and other means to accelerate cooling, but the quartz boat needs to reach a certain temperature after welding before it can be safely unloaded, otherwise it will cause structural deformation or stress damage. Although this method shortens the cooling time, it brings about the problem of increased energy consumption. The fan structure needs to run continuously to maintain a high air flow speed, which not only increases power consumption, but also puts higher requirements on energy management.

[0008] Secondly, the use of the fan structure requires maintaining a higher temperature during the cooling process to avoid stress damage to the quartz boat due to rapid cooling. Rapid cooling causes uneven temperature distribution inside the quartz boat, which in turn induces thermal stress and further causes cracks or deformation in the quartz boat, seriously affecting its structural integrity and service life. Therefore, in order to prevent stress damage, the operator has to maintain a higher temperature during the cooling process, which further increases energy consumption, results in unsatisfactory cooling effect, and prolongs the overall cooling time.

[0009] To this end, the present invention provides a semi-automatic quartz boat rapid welding device. Summary of the invention

[0025] Compared with the prior art, the beneficial effects of the present invention are as follows: 1. The double-threaded screw in the centering limit assembly rotates and indirectly drives the centering rod to move, thereby pushing the slot rod to the center position, ensuring that the slot rod can be automatically and accurately positioned in the middle of the device before welding, eliminating the position deviation that occurs during manual placement. This automatic positioning mechanism not only improves the consistency of welding, but also reduces the phenomenon of empty welding caused by human error. Secondly, the limiting pulling action of the limiting shell and the telescopic rod can prevent the centering rod from excessively pushing against the slot rod, further ensuring the accuracy and stability of the slot rod positioning. Therefore, the centering limit assembly reduces the complexity of operation, reduces the labor intensity of operators, and improves the automation level and convenience of operation of the overall production line.

[0026] Compared with the existing technology, the existing technology relies on manual position adjustment, which has problems of operational complexity and human error. The centering limit assembly eliminates these uncertainties through an automatic positioning mechanism, ensuring that the slot rods can be accurately aligned every time, thereby avoiding the occurrence of empty welding. Secondly, due to the uncertainty of the slot rod position in the existing technology, secondary processing is often required, which increases production costs and time. The improved design reduces the need for secondary processing through automatic positioning and limit pulling, reduces production costs, and improves production efficiency.

[0027] Among them: when the slot rod is heated by welding, the hot air naturally rises, and the hot air inside the boss acts on the surface of the slot rod through the heating hole, which reduces the temperature gradient in the welding process and improves the welding quality.

[0028] Among them: when heated, the diaphragm no longer blocks the heating hole, and when not heated, the diaphragm blocks the heating hole, which can prevent external dust and other impurities from entering, ensuring the cleanliness and long-term stability of the device.

[0029] Among them: the elastic effect of the telescopic rod can prevent the centering rod from excessively resisting the slot rod, and enable the centering rod to quickly detach from the slot rod, thereby ensuring the stability of the slot rod positioning and the convenience of operation.

[0030] Among them: because the edge of the centering rod is set as a bevel and the edge is chamfered, the bevel resistance of the centering rod can quickly detach from the slot rod, ensuring that the slot rod can be quickly and smoothly detached after positioning, thereby improving the smoothness and efficiency of the operation.

[0031] 2. When the slot rod welding is no longer heated, the diaphragm blocks the heating hole, and allows the hot air to enter the conversion disk and the injection tube through the acceleration tube, and finally act on the surface of the blade, thereby driving the blade to rotate. Since the hot air has lost most of the heat during the flow process, the rotation of the blade will act on the welding point of the slot rod and the side plate to exchange heat. The use of the remaining hot air after welding for heat exchange not only reduces the consumption of additional energy, but also makes full use of waste heat resources to achieve efficient use of energy. Secondly, the warm air has lost most of the heat during the flow process, making the cooling process more gentle, avoiding the thermal stress problem caused by rapid cooling, thereby reducing the structural deformation and stress damage risk of the quartz boat.

[0032] Compared with the prior art, the prior art uses a fan structure to accelerate cooling. Although the cooling time is shortened, it brings about increased energy consumption and thermal stress problems. The fan structure needs to run continuously to maintain a high air flow rate, which increases power consumption and puts higher requirements on energy management. In addition, rapid cooling causes uneven temperature distribution inside the quartz boat, triggering thermal stress, which further causes cracks or deformation in the quartz boat, seriously affecting its structural integrity and service life. The centering limit assembly uses the remaining hot air for heat exchange, which not only reduces the consumption of additional energy, but also avoids the thermal stress problem caused by rapid cooling. The gentle heat exchange assembly reduces energy consumption, which meets the requirements of modern industry for energy conservation, emission reduction and efficient production.

[0033] Among them: the mild heat exchange component does not require an additional driving source to realize the rotation of the base and blades, and uses waste heat for heat exchange, which not only saves energy, but also because the mild heat exchange process can well control the temperature gradient, which not only speeds up the cooling rate, but also does not cause stress at the weld, thereby improving the uniformity and safety of cooling.

[0034] Among them: the hot air will be accelerated when it enters the acceleration tube from the placement boss. Since the cross-sectional area of ​​the acceleration tube is small and the injection tube is even smaller, this design allows the hot air to obtain sufficient power before entering the blades, ensuring that the blades can rotate effectively and providing continuous power for the cooling process.

[0035] Among them: since the curvature of the middle area of ​​the curved structure is smaller, which means that the surface area of ​​this area is relatively small, the hot air is more easily concentrated and accelerated here. This concentrated and accelerated hot air can more effectively drive the rotation of the blades and reduce the resistance to air flow. BRIEF DESCRIPTION OF THE DRAWINGS

[0049] 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.

[0050] The existing technology adopted by the present invention: the driving mechanism includes two driving motors and four transmission shafts, one of which is installed on the top of the second clamp 13, and the other is installed on the outer surface of the limit shell 22. The four transmission shafts are arranged in a group of two, and each group of transmission shafts passes through the surface of the second clamp 13 and is rotatably connected to the middle part of the second clamp 13. The transmission shaft and the driving motor are connected by belt drive, and each transmission shaft is also connected to the double-threaded screw 25 by belt drive.

[0051] The welding tool 14 includes two welding guns, a first external screw rod, an external welding motor, a first guide rail and a nut seat. The first guide rail is fixedly connected to the top of the welding platform 11, and the nut seat is slidably connected to the top of the first guide rail. The external welding motor is installed on the top of the welding platform 11, and the first external screw rod is installed on the output shaft of the external welding motor. The first external screw rod is threadedly connected to the inner surface of the nut seat, and the welding gun is symmetrically installed on the outer surface of the nut seat.

[0052] The first clamp 12 includes two slides, a bidirectional threaded screw, two pneumatic clamps, a plurality of side slots and a clamping motor. The clamping motor is installed on the top of the welding platform 11. The two slides are symmetrically slidably connected to the top of the welding platform 11. The bidirectional threaded screw is installed on the output shaft of the clamping motor, and the bidirectional threaded screw is threadedly connected to the inside of the two slides. The pneumatic clamps are all installed on the outer surface of the slide, and the side slots are all installed on the outer surface of the slide.

[0053] It should be noted that the above-mentioned drive motors, transmission shafts and other devices can all adopt relevant products available on the market. The structure and working principle of these products belong to the existing technology and will not be elaborated in the following.

[0054] Embodiment 1: Figure 1 As shown, a semi-automatic quartz boat quick welding device is used for centering and limiting the slot rod and for heat exchange at the welding point between the slot rod and the side plate, and includes a welding platform 11, first clamps 12 are symmetrically installed on both sides of the welding platform 11, a second clamp 13 is symmetrically installed in the middle of the welding platform 11, welding tooling 14 is installed on the top of the welding platform 11 in a rectangular and equidistant arrangement, and a centering and limiting component 2 for preventing unequal distances between the slot rod and the nail side plate is symmetrically arranged on the outer side of the second clamp 13.

[0055] The centering limit assembly 2 includes a plurality of centering rods 24 for adjusting the position of the slot rods through self-interference and a plurality of placement bosses 28 for holding the slot rods. The side of the centering rod 24 away from the center of the second clamp 13 is set as an inclined surface, and the side of the centering rod 24 close to the center of the second clamp 13 is provided with a sliding groove.

[0056] like Figures 3 to 8 As shown, the centering limit assembly 2 also includes a plurality of top plates 21, which are rectangular, equidistant and symmetrically fixedly connected to the outer surface of the second clamp 13, the bottom of each top plate 21 is fixedly connected to the limit shell 22, each limit shell 22 has a limit groove running through the surface, the inside of the limit groove on the surface of the limit shell 22 is slidably connected to the limit column 23, the bottom of the limit column 23 is fixedly connected to the top of the centering rod 24, each second clamp 13 runs through the surface and is rotatably connected to two double-threaded screws 25, the outer wall of each second clamp 13 is fixedly connected to the limit strip, the outer surface of each double-threaded screw 25 is threadedly connected to a nut pair 26, and each nut pair 26 is slidably connected to the outer surface of the limit strip The nut pair 26 is fixedly connected to a telescopic rod 27 on one side away from the center of the second clamp 13, and the output end of the telescopic rod 27 is slidably connected to the inside of the slide groove on the surface of the centering rod 24. The outer wall of the output end of the telescopic rod 27 and the inner wall of the slide groove are adapted to each other. The second clamp 13 is symmetrically fixedly connected to a receiving plate on the side close to each other, and the bottom of the placement boss 28 is fixedly connected to the top of the receiving plate. The placement boss 28 passes through the top and is linearly and equidistantly arranged with heating holes. A number of expansion shells 29 are fixedly connected to the inner wall of the placement boss 28 in a linear and equidistant arrangement. The inside of the expansion shell 29 is slidably connected to a piston rod 210, and the side of the piston rod 210 away from the expansion shell 29 is fixedly connected to a diaphragm 211.

[0057] It should be noted that a centering drive mechanism is installed on the outside of the centering limit assembly 2, and the centering drive mechanism is electrically controlled to start and stop by the electric control panel 15. The side of the limit groove on the surface of the limit shell 22 away from the center of the second clamp 13 is set to a bent state, the outer surface of the centering rod 24 is chamfered, and nitrogen is filled between the expansion shell 29 and the piston rod 210.

[0058] Specifically, the operator first places the side panel on the surface of the slide, ensures that the side panel is clamped in the side slot, and fixes the side panel by electrically controlling the pneumatic clamp through the electrical control panel 15, and then places the four slot bars evenly on the surface of the placement boss 28 to prepare for subsequent centering, limiting and welding, and then electrically controls the first clamp 12 to move closer to each other through the electrical control panel 15 to ensure that the positions of the side panel and the slot bar are accurately aligned.

[0059] Subsequently, the operator electrically controls the start of the drive motor through the electrical control panel 15, and the drive motor rotates the double-threaded screw 25 through a belt drive. The rotation of the double-threaded screw 25 causes the nut pair 26 on its surface to move toward the side close to the center of the first clamp 12, thereby driving the telescopic rod 27 and the centering rod 24 to move synchronously. The side of the centering rod 24 where the inclined surface is set will conflict with the slot rod and drive the slot rod to slide on the placement boss 28. During this process, the limit column 23 will slide in the limit shell 22, causing the centering rod 24 to move away from the slot rod. At the same time, the telescopic rod 27 is elastically stretched, and its own elastic force accelerates the trend of the centering rod 24 to separate from the slot rod, ensuring that the slot rod can slide smoothly.

[0060] Finally, the limiting column 23 moves in a straight line inside the limiting shell 22, and the centering rod 24 no longer interferes with the slot rod. Through the threaded action of the double-threaded screw 25 itself, the centering rods 24 on both sides simultaneously center and limit the slot rod to ensure the accurate position of the slot rod. At this time, the operator can again use the electrical control panel 15 to make the first clamp 12 close to the second clamp 13, and then start the welding tooling 14 to make it close to the slot rod and the side, and weld it.

[0061] It should be noted that, in the above-mentioned process of welding the slot rod and the side plate, the air inside the placement boss 28 will expand due to the heat. Similarly, the nitrogen inside the expansion shell 29 will also expand due to the heat, and push the piston rod 210 under the action of pressure, and the piston rod 210 drives the diaphragm 211 to move synchronously, and no longer blocks the heating hole. At this time, the hot air in the placement boss 28 will overflow from the heating hole based on the principle of rising, and act on the part of the slot rod that is not heated by welding. Since the hot air in the placement boss 28 is not directly heated by the welding gun, its temperature is lower than the temperature of the welding point. By heating the remaining surface of the slot rod at a slightly lower temperature, a temperature gradient can be prevented in the remaining part of the slot rod.

[0062] Therefore, this gentle heating of the unwelded parts of the slot rod can avoid local overheating or overcooling, thereby reducing the risk of stress concentration and deformation of the slot rod due to uneven temperature. In addition, it helps to improve the cooling efficiency after welding, ensure that the overall temperature distribution of the slot rod is more uniform, and further improve the welding quality and the structural stability of the quartz boat.

[0063] Embodiment 2: Based on Embodiment 1, Figure 7 and Figure 8 As shown, a mild heat exchange component 3 for exchanging heat at the welding point between the slot rod and the side plate is arranged on the outer side of the placement boss 28. The mild heat exchange component 3 includes a plurality of accelerating tubes 31. Every two accelerating tubes 31 are arranged as a group. Each group of accelerating tubes 31 are symmetrically fixed and connected to the side wall of the placement boss 28. One end of the accelerating tube 31 away from the placement boss 28 is rotatably connected to a conversion disk 32. The interior of the conversion disk 32 is arranged as a cavity.

[0064] like Figure 8 and Fig. 9 As shown, the mild heat exchange component 3 also includes a plurality of bases 33, each of which is fixedly connected to the top of the conversion disk 32, and the outer surface of the base 33 is fixedly connected with a plurality of blades 34 arranged equidistantly in a ring shape, and the outer surface of the conversion disk 32 is fixedly connected with a plurality of injection pipes 35, and the outer surface of the base 33 is fixedly connected with a plurality of mounting seats 36, and the injection pipes 35 are fixedly connected to the inner surface of the mounting seats 36.

[0065] It should be noted that an electric control panel 15 is installed on the top of the welding platform 11, and the electric control panel 15 electrically controls the start of the welding tooling 14 and the second clamp 13. The acceleration tube 31 is made of stainless steel, and the end of the injection tube 35 away from the acceleration tube 31 is connected to the middle of the bend of the blade 34.

[0066] Specifically, when welding is completed, the operator turns off the welding gun through the electric control panel 15. At this time, the hot air in the boss 28 loses its heat source and lowers its temperature. Therefore, the nitrogen in the expansion shell 29 contracts and, under the action of atmospheric pressure, the diaphragm 211 is reset and the heating hole is blocked through the piston rod 210. At this time, the hot air in the boss 28 loses space to escape and can only move toward the accelerating tube 31 and the two sides.

[0067] Since the heat exchange area between the placement boss 28 and the outside world is reduced, the inside thereof is hotter, and further residual hot air will enter the placement boss 28. This is because the density of the hot air inside the placement boss 28 is lower, while the density of the outside air is higher. According to the principle that hot air rises, the hot air will naturally rise upward and enter the accelerating tube 31. The accelerating tube 31 has a small cross-sectional area. Based on the Bernoulli principle in fluid mechanics, the hot air undergoes an acceleration process inside.

[0068] The same hot air eventually enters the conversion disk 32 through the accelerating tube 31. At this time, the speed of the hot air is already relatively fast, so when it is discharged from the conversion disk 32, it will act on the surface of the blade 34. Since the output end of the conversion disk 32 is connected to the bent middle part of the blade 34, based on the momentum conservation principle of fluid mechanics, the accelerated flow of the hot air in the conversion disk 32 will generate a forward momentum. When the hot air is discharged from the conversion disk 32, this momentum will be transmitted to the blade 34, driving it to rotate, and then the blade 34 drives the base 33 to rotate. As the blade 34 rotates, the hot air is discharged by the blade 34 to the welding point between the slot rod and the side plate. Since the hot air has been flowing for a long time at this time, the temperature is relatively mild. Furthermore, the mild hot air at this time will act on the welding point and exchange heat with the welding point, thereby achieving the effect of quickly cooling the welding point. This mild hot air flow can not only effectively reduce the temperature of the welding point, but also avoid the thermal stress caused by rapid cooling, thereby ensuring the quality and stability of the welding point.
