[0036] Please refer to Figure 11 , in one embodiment, the quartz boat 200 to be welded as required includes four groove rods 201 and two end plates 202. The four groove rods 201 are arranged in parallel, and are respectively connected to the end plates 202 at both ends. The end plates 202 are fixedly welded to the groove rods 201. A card slot 203 is provided on the inner side of each groove rod 201, and the card slot 203 is used for fixing silicon wafers. A plate column 204 is further provided on the outer side surface of the end plate 202. The plate column 204 is used to provide stable support and fixation, and serves as a handle when handling the quartz boat 200, so as to better control and operate the quartz boat 200.

[0037] Please refer to in combination Figures 1 to 10 , the present invention provides a quartz boat welding machine 100 for realizing the rapid and accurate welding operation of the above-mentioned quartz boat 200. The quartz boat welding machine 100 includes a chassis 10 and a groove rod positioning mechanism 20, an end plate positioning mechanism 30 and a welding mechanism 40 arranged on the chassis 10. Among them, the groove rod positioning mechanism 20 is used to support and position multiple groove rods 201, the end plate positioning mechanism 30 is used to clamp and position the two side end plates 202, and the welding mechanism 40 is used to weld and fix the groove rods 201 and the end plates 202.

[0038] Specifically, the groove rod positioning mechanism 20 includes a reference plate 21, a supporting component 22 and a pinning component 23. There are two reference plates 21, and the two reference plates 21 are arranged in parallel and vertically. The reference plate 21 has a first side wall 211 and two second side walls 212 perpendicular to the first side wall 211. Two groups of supporting components 22 are arranged up and down on each second side wall 212, and four groups of pinning components 23 are arranged on the first side wall 211. The four groups of pinning components 23 are arranged in a two-row and two-column manner, and the pinning components 23 correspond to the supporting components 22 one by one. Among them, the first side wall 211 can be the side wall (inner side wall) of the reference plate 21 facing the other reference plate, or the side wall (outer side wall) away from the other reference plate. In the embodiment shown in Figure 2 , the first side wall 211 is set as the side wall of the reference plate 21 facing the other reference plate. The supporting component 22 is used to support the groove rod 201, and the pinning component 23 is used to position the groove rod 201 to prevent the groove rod 201 from moving.

[0039] Further, the supporting component 22 includes a supporting rod 221 disposed on the second side wall 212 and a limiting block 222 disposed on the supporting rod 221. A supporting position for supporting the groove rod 201 is formed among the limiting block 222, the supporting rod 221 and the reference plate 21; the gear shaper component 23 includes a gear shaper mounting plate 231 disposed on the first side wall 211 and a gear shaper 232 disposed on the gear shaper mounting plate 231. The gear shaper 232 is arranged parallel to the supporting rod 221. A tooth portion 2321 for inserting into the slot 203 of the groove rod 201 is provided at the outer end of the gear shaper 232, and the structure of the tooth portion 2321 matches the structure of the slot 203. Thus, the groove rod positioning mechanism has eight corresponding supporting positions and eight gear shapers. In the quartz boat welding process, the groove rod 201 is placed in the corresponding supporting position, and the tooth portions 2321 of the respective gear shapers 232 are inserted into the appropriate slots 203, so as to effectively position the groove rod 201, avoid the shaking or displacement of the groove rod 201 during the welding process, and ensure the product precision.

[0040] Please refer to Figure 1 、 Figure 6 and Figure 7 As shown in, there are two groups of end plate positioning mechanisms 30. The two groups of end plate positioning mechanisms 30 are respectively disposed on both sides of the groove rod positioning mechanism 20, and the two groups of end plate positioning mechanisms 30 are oppositely arranged to fix the end plates 202 on both sides and push the end plates 202 on both sides towards the groove rod positioning mechanism 20. The end plate positioning mechanism 30 includes a first moving module 31, a moving frame 32, a positioning plate 33 and a vacuum tube 34. The first moving module 31 is disposed on the base frame 10, and the moving frame 32 is movably disposed on the first moving module 31 along the first direction X. The positioning plate 33 is disposed on the moving frame 32. A vacuum suction groove 331 is provided on the side of the positioning plate 33 facing the groove rod positioning mechanism 20, and the vacuum tube 34 is communicated with the vacuum suction groove 331. A first positioning member 332 is provided on the side edge of the positioning plate 33, and a second positioning member 333 is provided on the bottom edge of the positioning plate 33. In the quartz boat welding process, the end plate 202 is placed on the positioning plate 33. The side edge of the end plate 202 abuts against the first positioning member 332, and the bottom plate of the end plate 202 abuts against the second positioning member 333. The first positioning member 332 and the second positioning member 333 can position the end plate 202 to ensure the positioning accuracy; the other end of the vacuum tube 34 is connected to a vacuum suction device (not shown in the figure), so that the end plate 202 is adsorbed on the positioning plate 33 to effectively fix the end plate 202; the first moving module 31 is used to drive the moving frame 32 to move towards the groove rod positioning mechanism 20, so that the end plate 202 fits the groove rod 201 for convenient welding operation.

[0041] Please refer to Figure 1 、 Figures 8 to 10, there are two sets of welding mechanisms 40, and the two sets of welding mechanisms 40 are respectively arranged on both sides of the groove rod clamping mechanism 20; each set of welding mechanism 40 includes a second moving module 41, a cross plate 42, a third moving module 43, a welding torch fixing bracket 44 and a welding torch 45. The second moving module 41 is arranged on the chassis 10, and the cross plate 42 is movably arranged on the second moving module 41 along the first direction X; the third moving module 43 is arranged on the cross plate 42, and there are two welding torch fixing brackets 44, and the two welding torch fixing brackets 44 are respectively movably arranged on the third moving module 43 along the second direction Y; two welding torches 45 are arranged vertically on each welding torch fixing bracket 44.

[0042] It can be understood that in this embodiment, the first direction X is the length direction of the chassis 10, the second direction Y is the width direction of the chassis 10, and the second direction Y is perpendicular to the first direction X. In the quartz boat welding process, the groove rod 201 is fixed in the groove rod positioning mechanism 20, the end plate 202 is fixed in the end plate positioning mechanism 30, the second moving module 41 is used to drive the welding torch 45 to move along the first direction X, and the third moving module 43 is used to drive the welding torch 45 to move along the second direction Y, so that the nozzles of the welding torches 45 move to the welding points corresponding to the groove rod 201 and the end plate 202, thereby welding and fixing the groove rod 201 and the end plate 202. There are eight welding torches 45 in the two sets of welding mechanisms 40, which can simultaneously weld the eight welding points at both ends of the four groove rods 201, improving the welding efficiency.

[0043] The quartz boat welding machine 100 of the present invention uses the groove rod positioning mechanism 20 to position multiple groove rods 201, uses the end plate positioning mechanisms 30 on both sides to position the end plates 202 on both sides, and pushes the end plates 202 on both sides towards the groove rod 201, and uses multiple welding torches 45 in the welding mechanism 40 to weld simultaneously, so that the groove rod 201 and the end plate 202 are fixedly connected, with high positioning accuracy and high welding efficiency.

[0044] In some embodiments, the supporting rod 221 is arranged to be adjustable along a direction perpendicular to the second side wall 212. For example, a waist-shaped hole extending along a direction perpendicular to the second side wall 212 is arranged on the supporting rod 221, and the supporting rod 221 and the reference plate 21 are fixed by a positioning pin. By adjusting the fixing position of the positioning pin in the waist-shaped hole of the supporting rod 221, the position of the supporting rod 221 along a direction perpendicular to the second side wall 212 is adjusted, thereby adjusting the width of the supporting position to adapt to groove rods 201 of different sizes.

[0045] Such as Figure 2 and Figure 4As shown, in some other embodiments, the slot bar positioning mechanism 20 further includes a bottom plate assembly 24. The bottom plate assembly 24 includes a bottom plate 241, a rotating connecting plate 242, and a rotating shaft 243. The bottom plate 241 is fixed to the chassis 10. The rotating shaft 243 is rotatably provided in the middle of the bottom plate 241. The rotating connecting plate 242 is rotatably connected to the bottom plate 241 through the rotating shaft 243. Two reference plates 21 are fixed to the rotating connecting plate 242. By adjusting the angle of the rotating connecting plate 242, the angle of the slot bar 201 can be adjusted. In some models of quartz boats, a non-right-angle included angle is required between the slot bar 201 and the end plate 202, that is, the slot bar 201 is not perpendicular to the end plate 202. In the present invention, the angle of the slot bar 201 is adjusted by adjusting the angle of the rotating connecting plate 242, so that the welding process of quartz boats with different angles can be adapted, and the applicability of the equipment is improved.

[0046] Further, an arc-shaped adjustment hole 244 is provided on the rotating connecting plate 242. The arc-shaped adjustment hole 244 is located around the rotating shaft 243, which is convenient for fixing the bottom plate 241 and the rotating connecting plate 242 after the angle of the rotating connecting plate 242 is adjusted.

[0047] In some other embodiments, an adjustment groove 213 extending in a direction perpendicular to the second side wall 212 is provided on the first side wall 211 of the reference plate 21. A clamping block 2311 is correspondingly provided on the pinion mounting plate 231. The clamping block 2311 is movably provided in the adjustment groove 213. Among them, the width of the adjustment groove 213 in the direction perpendicular to the second side wall 212 is greater than the width of the clamping block 2311 in the direction perpendicular to the second side wall 212. When positioning the slot bar 201, the pinion mounting plate 231 can be first pushed inward in the direction perpendicular to the second side wall 212 to place the slot bar 201 in the supporting position, avoiding the pinion 232 from obstructing the slot bar 201, and then the pinion mounting plate 231 is pushed outward in the direction perpendicular to the second side wall 212 to make the pinion 232 insert into a suitable card slot 203 to position the slot bar 201. In addition, the cooperation between the clamping block 2311 and the adjustment groove 213 can also be adapted to different models of slot bars 201, improving the applicability of the welding machine 100.

[0048] Further, the slot bar positioning mechanism 20 further includes a connecting rod 25. The two ends of the connecting rod 25 are respectively connected to the inner ends of two pinions 232 in the upper and lower groups of pinion assemblies 23. By pulling the connecting rod 25 left and right in the direction perpendicular to the second side wall 212, the two pinions 232 can be moved simultaneously, which is convenient for operation.

[0049] Furthermore, the pinion assembly 23 further includes a spring block 233. The spring block 233 is sleeved on the pinion 232, and the spring block 233 is located between the pinion mounting plate 231 and the connecting rod 25. The spring block 233 is used to fix and position the pinion 232 and reduce vibration.

[0050] As shown Figure 6 In some embodiments, the first moving module 31 includes a first guide rail 311, a first slider 312, a first motor 313, a lead screw 314 and a nut seat 315. The first guide rail 311 is disposed on the chassis 10 along the first direction X. The first slider 312 is movably disposed on the first guide rail 311 along the first direction X. The lead screw 314 is rotatably disposed on the chassis 10 and is parallel to the first guide rail 311. The output shaft of the first motor 313 is connected to the lead screw 314. The nut seat 315 is in threaded engagement with the lead screw 314. The bottom surface of the moving frame 32 is fixedly connected to the first slider 312 and the nut seat 315. Among them, the first guide rail 311 and the first slider 312 can adopt commercially available linear guide rail module products. Two sets of linear modules composed of the first guide rail 311 and the first slider 312 can be arranged in parallel. Both ends of the lead screw 314 can be installed through bearing seats, and the lead screw 314 is disposed between the two sets of linear modules. The nut seat 315 is in threaded engagement with the lead screw, and the nut seat is restricted from rotating and can only move along the first direction. In application, the first motor 313 drives the lead screw 314 to rotate, and the nut seat 15 then moves along the first direction X on the lead screw 314, drives the first slider 312 to move along the first guide rail 311, and drives the moving seat 32 to move along the first direction X, so as to drive the end plate 202 to move towards the groove bar positioning mechanism 20, make the end plate 202 fit the groove bar 201 for welding operation, and reset the moving frame 32 after welding is completed.

[0051] Of course, the present invention is not limited thereto. In other embodiments, the first moving module 31 can also adopt other reasonable structures as long as it can realize the movement control of the moving frame 32 along the first direction X.

[0052] Furthermore, the end plate positioning mechanism 30 further includes a first sensing component 35. The first sensing component 35 includes a first photoelectric sensor 351 and a first sensing piece 352. The first photoelectric sensor 351 is disposed on the side of the first guide rail 311, and the first sensing piece 352 is disposed on the first slider 312. The first photoelectric sensor 351 can adopt commercially available photoelectric sensor products, such as groove photoelectric sensors. The first photoelectric sensor 351 cooperates with the first sensing piece 352 to control the movement positioning accuracy of the moving frame 42. Specifically, when the first slider 312 moves, the first sensing piece 352 moves accordingly. When the first sensing piece 352 reaches the first photoelectric sensor 351, it means that the moving frame 32 has moved in place. According to the requirements of the welding process, multiple sets of the first sensing components 35 can also be provided to achieve more accurate positioning control.

[0053] In some embodiments, the first positioning member 332 has an L-shaped structure. A part of the first positioning member 332 is connected to the positioning plate 33, and the other part is perpendicular to the positioning plate 332, so as to limit the end plate 202. Further, the first positioning member 332 can be set to be adjustable along the second direction Y. For example, a kidney-shaped hole extending along the second direction Y is provided on the first positioning member 332. The first positioning member 332 is fixed to the positioning plate 33 by screws or the like. By adjusting the position of the screw in the kidney-shaped hole of the first positioning member 332, the position of the first positioning member 332 in the second direction Y can be adjusted, so as to be adapted to end plates 202 of different models. The second positioning member 333 can be set to be adjustable along the vertical direction. For example, a kidney-shaped hole extending along the vertical direction is provided on the second positioning member 333. The second positioning member 333 is fixed to the positioning plate 33 by screws or the like. By adjusting the position of the screw in the kidney-shaped hole of the second positioning member 333, the position of the second positioning member 333 in the vertical direction can be adjusted, so as to be adapted to end plates 202 of different models.

[0054] As Figure 7 shown, in some other embodiments, an avoidance groove 334 is provided on the positioning plate 33, so that the positioning plate 33 has an overall U-shaped structure. In this way, when the end plate 202 is fixed, the plate column 204 on the outer side of the end plate 202 can extend into the avoidance groove 334 to avoid errors.
