[0017] By driving the lead screw 1 to rotate through the work of servo motor 2, the two horizontal blocks can be driven to move toward or oppositely, thereby adjusting the distance between the two fixed plates so that the plate-shaped quartz boat contacts the rod-shaped quartz boat, which is convenient for subsequent welding operations. By driving a rotating shaft through the work of servo motor 3, since a conveyor belt is connected between the two rollers, the two rollers can be driven to rotate synchronously, so that the conveyor belt can transport the quartz boat materials to be welded. The staff only needs to take out the quartz boat materials from under the welding operating table, thereby reducing labor intensity.

[0018] The position of the threaded shaft inside the threaded groove can be adjusted by rotating the threaded shaft, thereby adjusting the height of the foot pad. The welding table can be leveled even on an uneven surface, thereby not affecting the welding operation. The bubble level embedded in the top of the frame can assist the leveling process.

[0034] Working principle: Before welding, it is necessary to detect the flatness of the end of the rod-shaped quartz boat and the uniformity of the surface of the plate-shaped quartz boat. The two ends of the rod-shaped quartz boat are respectively inserted into the two horizontal detection holes 11, and then the electric cylinder 32 is controlled to work so that the detection disk 31 presses against the end of the rod-shaped quartz boat.

[0035] The rod-shaped quartz boat is placed between the two semicircular fixing members 52. The servo motor 1 54 works to drive the driving shaft 56 and the driving gear 57 to rotate. Due to the meshing connection between the driving gear 57 and a driven gear 511, the driving gear 57 can drive the corresponding driven gear 511 to rotate, and due to the meshing connection between the two driven gears 511, the two driven gears 511 can rotate in the opposite direction. The two driven gears 511 drive the two semicircular fixing members 52 to rotate in the opposite direction through the corresponding driven shaft 510, the rotating member 59 and the connecting rod 55. When the two semicircular fixing members 52 are in contact, the rod-shaped quartz boat can be supported and fixed. The plate-shaped quartz boat is attached to the fixing plate 2. The servo motor 4 72 works to drive the driving shaft 56 and the driving gear 57 to rotate. The work drives the second lead screw 73 to rotate. Since the front and rear outer walls of the second lead screw 73 are provided with opposite threads, the two longitudinal blocks 74 can be driven to move toward or oppositely, thereby adjusting the distance between the two clamping rods 71, fixing the front and rear sides of the plate-like quartz boat, pulling the clamping plate 76 upward, so that the clamping plate 76 stretches the spring 79 and moves upward along the vertical axis 78, placing the plate-like quartz boat between the clamping plate 76 and the second clamping plate 77, and then driving the clamping plate 76 downward by the spring 79 until the clamping plate 76 and the second clamping plate 77 clamp the plate-like quartz boat, so that the non-welding surface of the plate-like quartz boat can be fixed, thereby increasing the stability of welding, thereby increasing the stability of welding the rod-like quartz boat and the plate-like quartz boat; The servo motor 2 62 drives the lead screw 1 61 to rotate. Since the outer walls of the lead screw 1 61 are provided with opposite threads, the two cross blocks 63 can be driven to move toward or opposite to each other, thereby adjusting the distance between the two fixed plates 2 so that the plate-shaped quartz boat contacts the rod-shaped quartz boat. The welding robot arm 10 can be operated to automatically weld the rod-shaped quartz boat and the plate-shaped quartz boat.
