Description

Technical Field

[0001] The invention belongs to the field of quartz boat welding, and in particular relates to a nail boat welding fixture and a processing method. Background Art

[0002] A quartz boat is a laboratory or industrial container made of high-purity quartz glass, typically used for material processing in high-temperature, corrosive, or high-purity environments. To prevent silicon wafers, wafers, or other sheet materials from slipping or shifting during high-temperature processing, small quartz spikes (bumps) are added to the supporting surface of the quartz boat to increase friction. This is called a pinned quartz boat or pinned boat.

[0003] During the production and processing of a quartz boat with nails, multiple quartz boat top plates need to be welded to two quartz boat support plates along their circumferential direction. Currently, during traditional quartz boat welding, two quartz boat support plates and multiple quartz boat top plates are typically secured with corresponding fixtures. The two quartz boat support plates are then brought closer together so that the surface of the support plates contacts the end faces of the quartz boat top plates. Workers then use handheld welding equipment to weld each quartz boat top plate to the support plates.

[0004] This traditional fixture for quartz boat welding has the following shortcomings: 1. When workers use handheld welding equipment for welding, because there are usually three quartz boat top plates, which are distributed around the circumference of the quartz boat support, workers need to constantly adjust the welding angle and position of the welding gun according to the welding position of the quartz boat top plates. Some quartz boat top plates are in a higher position, while others are in a lower position. This makes welding gun adjustment more difficult, consumes a lot of physical strength, and makes it difficult to ensure welding stability, thus affecting welding quality. 2. For long quartz boats, the quartz boat top plates are slender structures. When two quartz boat support platforms approach each other and collide with the slender quartz boat top plates, the slender quartz boat may bend and deform due to the squeezing force at both ends, which also affects welding quality.

[0034] The following is combined with Figure 1 -Attached Figure 9 This application is described in further detail.

[0035] Please refer to Figure 1 and Figure 2A nail boat welding fixture includes a base 1, on which two symmetrical mounting seats 2 are provided, a sliding mechanism 3 for driving the two mounting seats 2 to slide toward each other is provided between the two mounting seats 2 and the base 1, and a clamping mechanism 4 is provided on the opposite sides of the two mounting seats 2. A limit frame 5 for detecting and limiting the distance between the two mounting seats 2 is also fixedly provided on the base 1. The limit frame 5 cooperates with the sliding mechanism 3 to adjust the distance between the two mounting seats 2, and then the nail boat receiving platform 6 is fixed by the clamping mechanism 4. At the same time, the two corresponding clamping mechanisms 4 on the left and right can also jointly fix the nail boat top plate 7, and multiple nail boat top plates 7 are fixed between the left and right nail boat receiving platforms 6.

[0036] See Figure 1 and Figure 2 The sliding mechanism 3 includes two ear seats 1 fixedly arranged on the upper side of the base 1 and symmetrical on the left and right. A screw 1 31 is provided between the two ear seats 1 for rotating together. The middle part of the lower side of the mounting seat 2 is threadedly connected with the screw 1 31, and the threaded connection directions of the two mounting seats 2 and the same screw 1 31 are opposite. Two guide bars 32 are fixedly arranged on the base 1 and are symmetrical in front and back. The guide bar 32 is slidably connected to the lower side of the mounting seat 2.

[0037] See Figure 1 and Figure 2 The limit frame 5 includes an inverted U-shaped support plate 51 fixedly arranged on the middle part of the upper side of the base 1. The support plate 51 is movably sleeved on the surface of the screw 31. A telescopic rod 52 is fixedly arranged on the upper side of the horizontal section of the support plate 51. A connecting sleeve 53 is fixedly arranged on the upper end of the movable section of the telescopic rod 52. Both ends of the connecting sleeve 53 are threadedly connected to a limit rod 54. A pressure sensor (not shown in the figure) is fixedly arranged on the end surface of the limit rod 54 away from the connecting sleeve 53. A warning light 55 is fixedly arranged on the top of the movable section of the telescopic rod 52.

[0038] During specific work, in order to prevent the slender quartz boat top plate 7 from being bent by pressure when it is fitted with the quartz boat receiving platform 6, after the quartz boat receiving platform 6 is fixed by the clamping mechanism 4, the staff drives the limit rod 54 to rotate relative to the connecting sleeve 53, and the left and right limit rods 54 rotate and retract to ensure that the lengths of the two limit rods 54 extending out of the connecting sleeve 53 are the same and the same as the length of the quartz boat top plate 7. The staff then lifts the connecting sleeve 53 upward so that it is between the left and right quartz boat receiving platforms 6. The staff then controls the screw 31 to rotate so that the two mounting seats 2 approach each other, thereby bringing the two quartz boat receiving platforms 6 closer to each other and eventually causing the ends of the left and right limit rods 54 of the connecting sleeve 53 to contact the corresponding quartz boat receiving platforms 6. When the limit rods 54 contact the corresponding quartz boat receiving platforms 6, the pressure sensor on the end face of the limit rod 54 detects the pressure and transmits it to the external controller, which controls the warning light 55 to flash to prompt the staff to move the two quartz boat receiving platforms 6 to the predetermined position. At this time, the distance between the two quartz boat receiving platforms 6 is the length of the quartz boat top plate 7 to be welded. The limiting frame 5, which is the same length as the quartz boat top plate 7, is used to replace the quartz boat top plate 7 so as to contact the left and right quartz boat receiving platforms 6. After adjusting the distance between the two quartz boat receiving platforms 6, the quartz boat top plates 7 are installed one by one between the two quartz boat receiving platforms 6 and fixed. This ensures that the end surface of the quartz boat top plate 7 is in contact with the quartz boat receiving platforms 6 while not being subjected to pressure from the quartz boat receiving platforms 6 on the quartz boat top plate 7, thereby preventing the slender quartz boat top plate 7 from bending when the end is subjected to pressure in the length direction.

[0039] See Figure 2 、 Figure 3 、 Figure 4 and Figure 5The clamping mechanism 4 includes a disc-shaped clamping platform 41 rotatably mounted on the sidewall of the mounting base 2. Multiple guide rods 42 and multiple pressing frames 43 are arranged along the circumference of the clamping platform 41, away from the corresponding mounting base 2. These guide rods 42 and pressing frames 43 are staggered and connected to an adjustment assembly 44. Multiple locking assemblies 45 are arranged along the circumference of the clamping platform 41, each corresponding to one of the pressing frames 43. The guide rods 42 on the clamping platform 41 form a guide channel for guiding the installation of the quartz boat receiving platform 6. This allows the quartz boat receiving platform 6 to slide centrally toward the corresponding clamping platform 41 via the guide rods 42 and adhere to the surface of the clamping platform 41. Simultaneously, the pressing frames 43 compress the quartz boat receiving platform 6 after adhesion. The quartz boat top plate 7 is fixed between the two corresponding pressing frames 43 on the left and right. During subsequent welding, the position of the quartz boat top plate 7 can be adjusted by rotating the clamping platform 41, and the clamping platform 41 can be locked by the locking assembly 45. The quartz boat top plate 7 can be adjusted to a suitable position for welding as much as possible.

[0040] See Figure 4 、 Figure 5 and Figure 6 In order to adapt to a variety of different diameters of the nail-bonding quartz boat receiving platform 6, the clamping platform 41 is provided with a plurality of slide grooves evenly distributed along its circumferential direction on the side away from the corresponding mounting seat 2. The adjusting component 44 includes a screw rod 2 441 rotatably arranged in the slide groove 1, and a slider 1 442 is threadedly connected to the screw rod 2 441. The slider 1 442 is slidably arranged in the slide groove 1. The guide rod 42 is vertically fixed on the corresponding slider 1 442. The pressing frame 43 is connected to the corresponding slider 1 442. A driving cavity is provided in the middle of the clamping platform 41. One end of the screw rod 2 441 movably extends into the driving cavity and is fixedly connected to a bevel gear 1 443. A bevel gear 2 444 that meshes with the bevel gear 1 443 is provided in the driving cavity through a rotating shaft 1. One end of the rotating shaft 1 movably passes through the side wall of the clamping platform 41 and is fixedly connected to a cross turntable 445. The staff rotates the cross-shaped turntable 445 to drive the rotation shaft 1, which in turn rotates the bevel gear 2 444 to simultaneously rotate the multiple bevel gears 1 443, thereby simultaneously tightening or expanding the multiple guide rods 42 and the multiple pressing frames 43 relative to the center of the clamping platform 41. The guide channel formed by the guide rods 42 and the pressing position of the pressing frames 43 are adjusted.

[0041] See Figure 3 and Figure 5The pressing frame 43 includes a rotating portion 431 connected to a corresponding slider 442. The rotating portion 431 is provided with a clamping portion 432 for clamping the end of the quartz boat top plate 7. The clamping portion 432 is provided with a pressing portion 433 that cooperates with the rotating portion 431 to press the quartz boat receiving platform 6. Before the quartz boat receiving platform 6 is installed, the rotating portion 431 is first rotated in the opposite direction to make way. Then, after the quartz boat receiving platform 6 is installed on the clamping platform 41, the rotating portion 431 is rotated forward to return to its original position so that the pressing portion 433 contacts the surface of the quartz boat receiving platform 6 to fix the quartz boat receiving platform 6. At the same time, the two corresponding clamping portions 432 on the left and right can cooperate to fix the quartz boat top plate 7.

[0042] See Figure 3 、 Figure 5 、 Figure 7 and Figure 8 The rotating part 431 includes two ear seats 3 fixedly set on the corresponding slider 1 442, and the two ear seats 3 are connected to the rotating shaft 2 4311 for common rotation. Torsion springs 4312 are respectively provided between the two ends of the rotating shaft 2 4311 and the corresponding ear seats 3. A T-shaped connecting plate 4313 is fixedly provided on the rotating shaft 2 4311, and a spring locking pin 4314 is slidably inserted into any one of the ear seats 3 on the same slider 1 442, and one end of the spring locking pin 4314 is movably inserted into the end face corresponding to the end of the rotating shaft 2 4311. The spring locking pin 4314 locks the second shaft 4311, and the torsion spring 4312 is in a compressed state. When the quartz boat receiving platform 6 needs to be fixed, the staff can pull the spring locking pin 4314 outward to release the lock on the second shaft 4311. The second shaft 4311 rotates under the reset of the torsion spring 4312, and drives the pressing portion 433 and the clamping portion 432 to rotate forward, so that the pressing portion 433 contacts the surface of the quartz boat receiving platform 6. When the quartz boat receiving platform 6 needs to be removed from the clamping platform 41, the staff holds the clamping portion 432 and rotates the second shaft 4311 in the opposite direction. After the second shaft 4311 rotates a certain angle, the spring locking pin 4314 automatically engages with the corresponding position of the end surface of the second shaft 4311, so that the pressing frame 43 no longer hinders the quartz boat receiving platform 6, making it convenient to remove the quartz boat receiving platform 6 later.

[0043] See Figure 5 、 Figure 7 、 Figure 8 and Figure 9To facilitate adjustment and securing of the quartz boat support 6 and the quartz boat top plate 7, the clamping portion 432 includes two ears 4 fixedly mounted on the longer end of the T-shaped connecting plate 4313. A screw 4321 is rotatably connected between the two ears 4. The screw 4321 has two threaded sections with opposite thread directions, each of which is threadedly connected to an L-shaped clamping plate 4322. A contact bar 4323 is fixedly mounted on the opposite sides of the longer ends of the two corresponding L-shaped clamping plates 4322. A slide groove 2 is defined on the side of the two contact bars 4323 that is adjacent to each other and away from the corresponding T-shaped connecting plate 4313. A screw 5 4324 is rotatably mounted within the slide groove 2. A slider 4325 is threadedly connected to the screw 5 4324. A limiting protrusion 4326 is fixedly mounted on the side of the two sliders 4325 that is adjacent to each other. Rotating screw rod 5 4324 causes slider 2 4325 to move within slot 2, thereby adjusting the radial position of stop protrusion 4326 on clamping platform 41. After the end of the quartz boat top plate 7 slides radially along clamping platform 41 into the corresponding two L-shaped clamping plates 4322, it stops until the end of the quartz boat top plate 7 contacts the stop protrusion 4326. The operator then rotates screw rod 4321 forward, causing the two L-shaped clamping plates 4322 to move closer together, thereby clamping and securing the end of the quartz boat top plate 7. To subsequently remove the quartz boat receiving platform 6 and quartz boat top plate 7, screw rod 4321 is rotated backward, causing the two L-shaped clamping plates 4322 to move away from each other, simultaneously moving the corresponding stop protrusion 4326 away from the quartz boat top plate 7, facilitating subsequent rotation and resetting of the L-shaped clamping plates 4322.

[0044] See Figure 5 、 Figure 7 and Figure 8 To accommodate quartz boat support platforms 6 of varying thickness, the abutment portion 433 includes two six screws 4331, which are rotatably mounted on the corresponding longer sections of the L-shaped clamping plates 4322. A disc-shaped rubber pad 4332 is fixedly mounted on one end of each screw 4331. As the thickness of the quartz boat support platform 6 changes, a worker rotates the six screws 4331 to move the rubber pad 4332 closer to or further away from the clamping platform 41. This ensures that the rubber pad 4332 contacts the quartz boat support platform 6 after rotation, and that the six screws 4331 remain perpendicular to the corresponding quartz boat support platform 6.

[0045] See Figure 4 and Figure 5The locking assembly 45 includes a second ear seat 451 fixedly connected to the outside of the clamping platform 41. A locking bolt 452 is threadedly connected to the second ear seat 451. One end of the locking bolt 452 movably contacts the side wall of the corresponding mounting base 2. Under normal conditions, the locking bolt 452 does not contact the side wall of the mounting base 2. The clamping platform 41 can be rotated and locked by turning the locking bolt 452.

[0046] In addition, the present invention also provides a method for welding a nail boat, which is completed in conjunction with the above-mentioned nail boat welding fixture, and includes the following steps: S1, parameter adjustment: 1. Adjusting the distance between multiple guide rods 42 and multiple pressing frames 43 on the same clamping platform 41 according to the different diameters of the nail quartz boat receiving platform 6. Specifically, by rotating the cross turntable 445, the screw 2 441 rotates and drives the corresponding slider 1 442 to slide, so that the guide rod 42 and the pressing frame 43 slide radially along the clamping platform 41 to adjust the distance, so that the guide channel formed by the multiple guide rods 42 on the clamping platform 41 can guide the nail quartz boat receiving platform 6 to be welded to the center and fit it with the clamping platform 41.

[0047] 2. Adjust the rubber pad 4332 according to the thickness of the quartz boat receiving platform 6. The staff rotates the screw 4331 to drive the rubber pad 4332 to move relative to the longer section of the L-shaped clamping plate to adjust the distance between the two.

[0048] 3. Adjust the limiting protrusion 4326 according to the radial installation position of the quartz boat top plate 7 along the quartz boat receiving platform 6, and move the slider 2 4325 by rotating the screw 5 4324 to drive the limiting protrusion 4326 to move radially along the clamping platform 41.

[0049] S2. Fix the quartz boat receiving platform 6 for bonding nails. The quartz boat receiving platform 6 is slid onto the clamping platform 41 and fits against the side wall of the clamping platform 41 by the guide rod 42. Then, the pressing part 433 on the pressing frame 43 is rotated and fixed on the surface of the quartz boat receiving platform 6 to fix the quartz boat receiving platform 6 for bonding nails.

[0050] S3. Securing the quartz boat top plate 7: Adjust the spacing between the two clamping mechanisms 4 according to the length of the quartz boat top plate 7. The operator adjusts the distance between the two clamping platforms 41 using the sliding mechanism 3 and the limiting frame 5, ensuring that the distance between the left and right quartz boat receiving platforms 6, after being mounted on their respective clamping platforms 41, corresponds to the length of the quartz boat top plate 7 to be welded. At this point, the two ends of the quartz boat top plate 7 are secured by the clamping portions 432 of the corresponding left and right pressing frames 43. Multiple quartz boat top plates 7 are then secured to the two quartz boat receiving platforms 6 according to the pre-set mounting positions.

[0051] S4. Preliminary welding and shaping: The worker rotates any one of the clamping platforms 41 to rotate the quartz boat receiving platform 6 and the multiple quartz boat top plates 7 simultaneously. When the quartz boat top plates 7 are rotated to a suitable welding position (the specific adjustment position varies depending on the height and habits of different welders), the worker rotates the locking bolt 452 forward so that its end gradually contacts the corresponding mounting seat 2, locking the clamping platform 41 on the mounting seat 2. The worker then welds the connection between the quartz boat top plate 7 and the quartz boat receiving platform 6. The worker rotates the locking bolt 452 in the reverse direction to unlock the clamping platform 41, and then rotates the clamping platform 41 again to rotate the next quartz boat top plate 7 to be welded to the same position for welding again. This cycle repeats until the two quartz boat receiving platforms 6 and the multiple quartz boat top plates 7 are welded and fixed.

[0052] S5, after blanking and fixing the formed material, the staff rotates the pressing frames 43 in the opposite direction to release the lock on the quartz boat receiving platform 6, and then rotates the screw 31 to control the two mounting seats 2 to move away from each other, and the welded quartz boat can be removed from the clamping platform 41 as a whole.

[0053] S6, deep processing, after being taken off from the clamping table 41, the shaped nail-bonded quartz boat is further welded and polished.

[0054] The above descriptions are merely embodiments of the present invention and are not intended to limit the patent scope of the present invention. Any equivalent structure or equivalent process transformation made using the contents of the present invention description and drawings, or directly or indirectly applied in other related technical fields, are also included in the patent protection scope of the present invention.
