[0002] The quartz boat is a carrier tool for silicon wafers in diffusion, oxidation and other processes. Its production and processing method is to manually build the external structure and weld it with quartz side panels of various shapes according to product requirements; OP blocks are opaque quartz materials, which are generally welded to the two corners of the same side of ordinary quartz side panels, and then build a quartz boat with light-shielding requirements.

[0003] At present, the welding process of OP blocks and ordinary quartz side panels is mostly done manually. Since the OP block is small in size, the welding gap between it and the quartz side panel is very short and narrow.

Therefore, during each welding process, it is often necessary to repeatedly fine-tune and repair the position of the OP block and the quartz side panel in order to produce products that meet the requirements, which leads to a long production cycle and low efficiency for this type of quartz boat, making it difficult to meet the requirements of customers' bulk orders.

[0035] Further, such as Figure 3 , Figure 4 As shown, the adjustment assembly 23 includes two pairs of guide rails 231 fixed on the base 21, two pairs of sliders 232 respectively fixed to the bottom of the two slide seats 22 and respectively slidably connected to the two pairs of guide rails 231, a rotating shaft 232 rotatably arranged on the base 21 and horizontally located between the pair of guide rails 231, two sections of threads 234 opened on the rotating shaft 232 and rotating in opposite directions, a pair of nuts 235 respectively fixed to the bottom of the two slide seats 22 and respectively threaded 234 connecting the two sections of threads 234, the rotating shaft 232 is located below the two slide seats 22, and one end of the rotating shaft 232 is fixedly connected to a rotating handle 236;

[0036] The adjustment assembly 26 includes a pair of guide rails 261 fixed on the base 21, a pair of sliders 262 fixed on the bottom of the two slide seats 25 and sliding the two guide rails respectively, a screw rod 263 rotatably arranged on the base 21 and horizontally located between the two guide rails, and a nut 264 fixed on the bottom of the slide seat 25 and connected to the screw rod 263 by a thread 234. The screw rod is located below the slide seat 25, and one end of the screw rod is fixedly connected to a knob 265.

[0037] The adjustment component 29 comprises an inverted U-shaped support plate 291 fixed on the base 21, a guide rail 292 fixed on the top of the inverted U-shaped support plate 291, a slider 293 sliding on the guide rail 292, an inverted T-shaped support member (294) fixedly connected to the slider 293 and the bottom of the long slide plate 28, a stepper motor 295 fixedly installed on the top of the inverted U-shaped support plate 291, a screw rod 296 sliding through the inverted T-shaped support member (294) and having one end fixedly connected to the output end of the stepper motor 295, and a nut 297 fixed on the inverted T-shaped support member (294) and having a thread 234 connected to the screw rod 296;

[0038] The adjustment component 2b includes a pair of guide rails 2b1 fixed to the bottom of the long slide 28, a slider 72b2 fixed to the top of the short slide 2a and slidably connected to the guide rails 2b1, a guide rail 2b3 fixed to the bottom of the short slide 2a, a slider 72b4 sliding on the guide rail 2b3, and an I-shaped support member 2b5T fixedly connecting the slider 72b4 and the base 21. The two guide rails 2b1 are symmetrically located on both sides of the inverted T-shaped support member (294) and are perpendicular to the guide rails 292. The two guide rails 2b3 are in an "eight" shape with each other and are symmetrical on both sides of the guide rails 292. The spacing between the two guide rails 2b3 at one end close to the side plate clamp 7-24 is smaller than the spacing between the other ends of the two guide rails 2b3.

[0039] By adopting the above-mentioned adjustment component 1 23, adjustment component 2 26, adjustment component 3 29 and adjustment component 4 2b, not only can the sliding of slide seat 1 22, slide seat 25, long slide plate 28 and short slide plate 2a be controlled respectively, but the guide rail 5 2b3 and slider 75 2b4 in the adjustment component 4 2b can also utilize the power of the long slide plate 28 sliding relative to the inverted U-shaped support plate 291 to realize the sliding movement of the short slide plate 2a relative to the bottom of the long slide plate 28, which not only saves the cost of the adjustment component 4 2b, but also enables the long slide plate 28 and the short slide plate 2a to slide and work at the same time, further improving the clamping efficiency of the OP block 7.

[0040] Further, such as Figure 3 , Figure 6 and Figure 7As shown, a clamping assembly 5 for clamping the upper end surface of the OP block 7 is also provided on the L-shaped support block 72c, and the clamping assembly 5 includes a cavity 51 arranged inside the L-shaped support block 72c, a threaded rod 234 vertically fixed at the bottom of the cavity 51, a threaded cylinder 234 rotatably arranged on the L-shaped support block 72c and inserted into the internal thread 234 of the cavity 51 to connect with the threaded rod 234, a clamping ring disk 54 fixedly connected to the lower end of the threaded cylinder 234 and movably sleeved with the threaded rod 234, and a rotating handle 55 fixedly connected to the upper end of the threaded cylinder 234, the cavity 51 is located above the square support plate 2d, and an opening 2c1 connected to the cavity 51 is opened at the corner of the L-shaped support block 72c, and a part of the clamping ring disk 54 extends out of the cavity 51 from the opening 2c1 and clamps a corner of the upper end surface of the OP block 7.

[0041] By adopting the above-mentioned clamping assembly 5, when it is necessary to clamp the OP block 7 on the square support plate 2d, first insert the OP block 7 into the gap between the clamping ring disk 54 and the square support plate 2d, and then manually turn the rotating handle 55 to rotate the threaded 234 cylinder. Since the thread 234 of the threaded 234 cylinder is connected to the threaded 234 rod, and the threaded 234 rod is fixed to the bottom of the cavity 51, when the threaded 234 cylinder rotates, it will also slide downward along the threaded 234 rod. Finally, the clamping ring disk 54 connected to the bottom of the threaded 234 cylinder will slide downward in the cavity 51, and the part thereof extending out of the cavity 51 will gradually approach and clamp the upper end face of the OP block 7.

[0042] Further, such as Figure 7 As shown, an arc-shaped long hole 541 is opened on the clamping ring disk 54, a limiting column 511 is fixedly arranged in the cavity 51 and slides through the long hole 541, a right-angle notch 542 is opened on the clamping ring disk 54, and when the limiting column 511 is located at one end of the long hole 541, the other parts of the clamping ring disk 54 except the right-angle notch 542 are all located inside the cavity 51.

[0043] By adopting the above technical solution, when it is necessary to take out the finished product after welding, it is only necessary to manually turn the rotating handle 55 in the opposite direction to make the clamping ring disc 54 rotate in the opposite direction and slide upward. When the limiting column 511 slides to one end of the clamping ring disc 54, the rotating handle 55 will be stuck and cannot be rotated further. At this time, except for the right-angle notch 542, all other parts of the clamping ring disc 54 are located inside the cavity 51, so that the upper end surface of the OP block 7 is not blocked, thereby facilitating the staff to quickly take out the finished product. Among them, the long hole 541 and the limiting column 511 can also limit the rotation angle range of the clamping ring disc 54, thereby preventing the right-angle notch 542 from reappearing in one rotation direction.

[0044] Further, such as Figure 3 , Figure 7As shown, a plurality of ratchet teeth 543 are evenly arranged on the contour of the clamping ring disk 54, a ratchet 512 is hingedly arranged in the cavity 51, a spring 513 is commonly connected to a corner in the cavity 51 and one side of the ratchet 512, and the spring 513 acts on the claw hook of the ratchet 512 to be clamped into the gap between the adjacent ratchet teeth 543, and an opening 2c2 is opened on the side of the L-shaped support block 72c away from the square support plate 2d to communicate with the cavity 51, and one end of the ratchet 512 is extended from the opening 2c2. 2c2 extends out of the cavity 51, and the rotation center of the pawl 512 is located between the spring 513 and the second opening 2c2. A pair of limit plates 281 are fixedly arranged on the long slide 28. When the distance between the two short slides 2a is the largest, one side of the two limit plates 281 respectively covers the second opening 2c2 on the two L-shaped support blocks 72c, and one end of the pawl 512 extending out of the cavity 51 is pressed back into the cavity 51 by the limit plate 281, and the claw hook at the other end of the pawl 512 exits the gap of the ratchet tooth 543.

[0045] By adopting the above-mentioned structures such as the ratchet 543, the pawl 512 and the spring 513, the clamping ring disk 54 can be locked when the clamping ring disk 54 presses the OP block 7, and then before the welding of the OP block 7 and the quartz boat side plate 6 is completed, it can be ensured that the clamping ring disk 54 can maintain a stable clamping posture at all times to prevent the OP block 7 from loosening upwards and affecting the welding quality. By adopting the above two limit plates 281, after the welding of the OP block 7 and the quartz boat side plate 6 is completed, the two short slide plates 2a will slide in the direction away from each other, and at the same time, the two L-shaped support blocks 72c will approach the two limit plates 281 on the long slide plate 28, until the two limit plates 281 cover the openings 2c2 on the two L-shaped support blocks 72c. At this time, the end of the ratchet 512 extending out of the cavity 51 is pressed back into the cavity 51 by the limit plate 281, and the claw hook at the other end of the ratchet 512 exits the gap of the ratchet teeth 543, so the locking of the clamping ring disc 54 will be released at this time, and the staff can turn the rotating handle 55 to reset the clamping ring disc 54. Among them, the end of the ratchet 512 extending out of the cavity 51 from the opening 2c2 can also be pressed back into the cavity 51 by tools or manually, so as to release the locking of the clamping ring disc 54 at any time.

[0046] The working principle of this embodiment:

[0047] When the quartz boat side plate 6 and the OP block 7 need to be clamped, first manually shake the rotating handle 236 to rotate the rotating shaft 232. Since the nuts 235 at the bottom of the two slides 22 are connected to the threads 234 on the two ends of the rotating shaft 232 with opposite rotation directions, the two nuts 235 will respectively drive the two slides 22 to slide in the direction of approaching or moving away from each other when the rotating shaft 232 rotates, until the spacing between the side plate clamping blocks 7-24 on the two slides 22 can ensure that the two sides of the quartz boat side plate 6 are placed flat on the right-angle grooves 241 of the two side plate clamping blocks 7-24.

[0048] Then, the knob 265 is manually turned to rotate the screw rod 1 263. Since the nut 264 at the bottom of the slide 25 is connected to the screw rod 1 263 by the thread 234, the nut 264 will drive the slide 25 to move toward the side of the quartz boat side plate 6 under the rotation of the screw rod 1 263, until the right-angle groove 271 on the side plate clamp 727 supports and contacts one side of the quartz boat side plate 6; then, an OP block 7 is placed on each of the square support plates 2d of the two L-shaped support plates U, and the OP block 7 is pressed and fixed on the side by the clamping assembly 5. Then, the stepper motor 295 is started to drive the screw rod 296 to rotate, so that the nut 3 297 connected to the screw rod 296 by the thread 234 drives the inverted T-shaped support member (294) to slide close to the quartz boat side plate 6. Since the long slide plate 28 is fixed on the top of the inverted T-shaped support member (294), and the short slide plates 2a connected to the two L-shaped support blocks 72c slide on the bottom of the long slide plate 28, the two L-shaped support plates U will each carry the OP block 7 thereon and gradually approach the quartz boat side plate 6 when the inverted T-shaped support member (294) moves.

[0049] At the same time, because the sliders 7-2b4 on the two I-shaped support members 2b5T on the base 21 are respectively slidably connected to the guide rails 5 2b3 at the bottom of the two short slides 2a and are in an "eight" shape with each other, during the sliding process of the long slide 28, the two short slides 2a will also slide at the bottom of the long slide 28 in a direction close to each other, thereby shortening the distance between the two OP blocks 7 until the distance between the two OP blocks 7 is consistent with the distance between the two corners of the quartz boat side plate 6; then, the knob 265 is turned again to make the side plate clamping block 7-27 push the quartz boat side plate 6 to move closer to the OP block 7 until the OP block 7 is completely spliced ​​into the corner of the quartz boat side plate 6; finally, the rotating handle 236 is manually cranked again to make the two side plate clamping blocks 7-24 further approach each other, and cooperate with the right-angle groove 241 thereon to clamp and fix the two sides of the quartz boat side plate 6, thereby completing the clamping and positioning of the quartz boat side plate 6 and OP.

[0050] When it is necessary to weld the quartz boat side plate 6 and the OP block 7, first, the two ball screw type linear modules 31 will respectively drive the two welding brackets 32 to move in the direction close to each other, and then the upper welding gun 33 and the lower welding gun 34 on the two welding brackets 32 will be moved to the upper and lower positions of the two OP blocks 7 respectively under the movement of the welding bracket 32, and make the L-shaped upper welding gun 33 and the lower welding gun 34 respectively aligned with the L-shaped welding gap between the OP block 7 and the quartz boat side plate 6. Since the upper welding gun 33 and the lower welding gun 34 are symmetrically located on the upper and lower sides of the L-shaped support block 72c, and the flame nozzle 35 faces the welding gap between the quartz boat side plate 6 and the OP block 7, the upper welding gun 33 and the lower welding gun 34 are ignited at this time, and the quartz boat side plate 6 and the OP block 7 can be welded at high temperature.
