Description

Technical Field

[0001] This utility model belongs to the field of automation equipment, and in particular relates to a fully automatic offline barium spraying device for quartz crucibles. Background Technology

[0002] Quartz crucibles, with their advantages of high purity, strong temperature resistance, large size, high precision, good heat insulation, energy saving, and stable quality, are increasingly widely used. Quartz crucibles are essential equipment for pulling large-diameter single-crystal silicon. In the single-crystal silicon production process, quartz crucibles need to hold molten silicon at high temperatures and prevent oxidation. However, quartz sand easily mixes with single-crystal silicon at high temperatures, leading to a decrease in the quality of the single-crystal silicon. Research has found that coating the inner wall of a quartz crucible with a layer of barium ion compound can promote the crystallization of the inner layer of the quartz crucible, forming tiny, dense cristobalite crystals. This crystalline layer is not easily washed away by the silicon solution, and even if small particles peel off, they are more easily melted in the high-temperature melt, thereby improving the quality and crystal growth performance of the single-crystal silicon. Traditional artificial barium coating has many drawbacks, such as the easy introduction of excess impurities and uneven coating. Utility Model Content

The first baffle 81 and the second baffle 82 are slidably installed inside the housing 1, and the first lifting cylinder 83 is installed inside the housing 1. The output end of the first lifting cylinder 83 is connected to the first connecting plate; thus realizing the lifting and lowering of the first baffle 81. The second lifting cylinder 84 is installed on the first baffle 81. The output end of the second lifting cylinder 84 passes through the first connecting plate and connects to the second connecting plate to realize the lifting of the second baffle 82.

[0029] The baffle assembly 8 can divide the limited space of the box 1, preventing the paint from spreading during the spraying process and affecting other equipment or other crucibles to be sprayed.

[0030] Preferably, the housing 1 is further provided with a first guide seat and a second guide seat. A guide rod 85 is installed that passes through a guide seat 1 and is fixedly connected to a connecting plate 1. Simultaneously, the guide rod 85 also contacts the lower surface of a connecting plate 2; thus, the guide rod 85 acts simultaneously on both the connecting plate 1 and the connecting plate 2. The second guide rod 86 passes through the second guide seat and the first connecting plate, and is fixed to the second connecting plate to achieve linear guidance of the second baffle 82.

[0031] Working principle: Conveyor 2 is in a waiting state; the baffle assembly 8 (baffles 1 and 2 82) of the barium spraying zone is in a lowered state, connecting the transport zone and the barium spraying zone; the gripper mechanism 6 is positioned above conveyor 2 and ready to be activated; the quartz crucible to be sprayed with barium is placed onto conveyor 2 by the previous process or manually. Conveyor 2 is activated, transporting the crucible to the designated pick-up station inside the housing 1; When the crucible arrives at the picking station, the controller issues a command: the first lifting cylinder 83 is activated, raising the first baffle 81. Subsequently, the second lifting cylinder 84 is activated, raising the second baffle 82, thus initially isolating the transport area and the barium spraying area; ensuring that the high-cleanliness environment of the barium spraying area is not disturbed. The controller commands the horizontal moving mechanism 3 and the vertical moving mechanism 4 to move, driving the gripper mechanism 6 to move directly above the crucible; then, the vertical moving mechanism 4 descends, causing the gripper mechanism 6 to reach the gripping height; the first and second gripper drive cylinders 65 operate simultaneously, pushing the first and second gripper assemblies 62 to move towards each other along the slide rail; through the linkage of the synchronous belt 66, the two gripper assemblies are ensured to close synchronously and symmetrically; the rollers 6132 on the gripper frame gently and stably grip the outer wall of the crucible; After the gripper mechanism 6 grabs the crucible, the vertical moving mechanism 4 lifts the crucible, and then the horizontal moving mechanism 3 transports it to the top of the barium spraying area; the horizontal and vertical moving mechanisms 4 make fine adjustments to lower the crucible to the preset spraying height; the rotating mechanism 5 starts working, driving the gripper mechanism 6 and the crucible to rotate slowly and uniformly at 360°. At the same time, the barium spraying mechanism 7 starts to operate; the robotic arm 71 moves according to the preset program, precisely extending the nozzle 77 into the rotating crucible; driven by the robotic arm 71, the nozzle 77 moves along the planned path on the inner wall of the crucible, ensuring that the barium slurry is evenly sprayed on every part of the inner surface of the crucible; the combination of the rotation of the crucible and the movement of the nozzle 77 achieves full coverage of the inner wall of the crucible without dead angles, greatly ensuring the uniformity of the coating. After the preset spraying program is completed, the nozzle 77 stops spraying liquid, and the robotic arm 71 retracts the nozzle 77 to the standby position. The rotating mechanism 5 stops, and the crucible stops rotating. During the waiting or intermittent time, the robotic arm 71 can move the nozzle 77 into the ultrasonic cleaner for automatic cleaning to prevent clogging. The gripper mechanism 6 lifts the crucible after barium spraying and sends it back to the top of the transfer mechanism 2 via the horizontal moving mechanism 3. The vertical moving mechanism 4 descends and places the crucible stably on the transfer mechanism 2. The gripper drive cylinder reverses its action, causing the gripper assembly to open and release the crucible. The baffle assembly 8 descends, the conveying mechanism 2 starts, and the processed crucible is sent out of the equipment to enter the next process; the gripper mechanism 6 moves back to the initial standby position, waiting for the next crucible to enter, and the above steps are repeated.

[0032] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
