Description
Technical Field
The invention relates to the technical field of graphite boat disassembly and assembly, in particular to an automatic disassembly and assembly system and an automatic disassembly and assembly method for a graphite boat.
Background
With the continuous reduction of the photovoltaic power generation cost, the solar power generation has wider market space. The graphite boat is used as a carrier when the solar cell is plated with the antireflection film, and the structure and the size of the graphite boat directly influence the conversion efficiency and the production efficiency of the silicon wafer. The automatic loading and unloading machine of the graphite boat places the silicon chips which are not coated with films on the clamping points of the graphite boat pages through the robot sucker, and each boat page can be placed with a fixed number of silicon chips. After all the silicon wafers are placed, the graphite boat is driven by a belt line to enter a PECVD coating machine. The silicon wafers on the graphite boat are subjected to specific chemical reaction in a PECVD coating machine under a high-temperature condition, so that the coating process on the surfaces of the silicon wafers is realized. And the graphite boat after the silicon wafer is coated is withdrawn from the PECVD, and then is transported to an automatic wafer loading and unloading machine through a belt line, and a robot of the automatic wafer loading and unloading machine station unloads the finished silicon wafer after the coating is finished from the graphite boat.
As shown in fig. 1-2, it is a structure diagram of a graphite boat in the prior art, wherein 1 is a graphite boat page, 2 is a ceramic rod, 3 is a graphite clamping point, 4 is a graphite nut, and 5 is a graphite boat base. Graphite boat page or leaf 1 is a rectangle thin slice, and the centre has opened the several quad slit, can install graphite stuck point 3 on the graphite boat page or leaf 1, and graphite stuck point 3 mainly is used for holding the silicon chip to guarantee that the silicon chip hugs closely graphite boat page or leaf 1. Graphite boat page or leaf 1 is separated by the ceramic sheathing and is opened between, and last all graphite boat page or leaf 1 is fixed by ceramic rod 2 again, and graphite nut 4 is installed again at the both ends of ceramic rod 2, and the graphite boat after the assembly is accomplished is by a large number, vertically place, the graphite boat page or leaf that is parallel to each other is constituteed, and graphite boat upper and lower width is unanimous, and interval is fixed and equal between the graphite boat page or leaf, and graphite boat page or leaf is perpendicular to ground. After the graphite boat goes in and out of the PECVD repeatedly, the thickness and the size of the groove between the graphite boat surface, the graphite boat sheet, the graphite clamping point, the tail end protrusion of the graphite clamping point and the graphite boat sheet are changed due to repeated film coating on the graphite boat surface. The size that the recess leads to the recess between the terminal arch of graphite stuck point and the graphite boat page or leaf can diminish because of the coating film many times, and after the recess size diminishes to a certain degree, this recess just can't be put into again to the silicon chip that does not coat the film to lead to the silicon chip to fall out from the graphite boat. Meanwhile, as the diameter of the groove of the graphite clamping point is very small, after the silicon wafer is repeatedly put in and taken out for many times, the diameter of the groove can be abraded, and the situation that the graphite clamping point is broken from the groove can be seriously caused.
Therefore, the graphite boat after being coated with the films for many times is taken out from the PECVD or automatic wafer loading and unloading machine periodically, the graphite boat is put into special cleaning equipment to clean redundant films on the surface, and meanwhile, the graphite boat needs to be disassembled manually, and then all clamping points on each graphite boat page are replaced. Because there are numerous graphite stuck points (for example, there are 24 graphite stuck points on a graphite boat page or leaf) on every graphite boat page or leaf, the manual work needs to carry out artifical stuck point to all graphite boat pages or leaves on a graphite boat and dismantle, and the stuck point is pressed in to manual dress stuck point and with special pressure tool again. Therefore, a large amount of operators are required to specially deal with the work of changing the stuck point, and great labor cost is brought to production.
At present, the blocking points are manually disassembled, a factory needs seven or eight persons to specially engage in the industry, meanwhile, because graphite is fragile, the graphite boat page is damaged due to inaccurate assembly caused by manual operation, and in addition, graphite dust has extremely strong pollution characteristics, so that the lung of a worker is greatly damaged, and the recruitment of the worker in the industry is difficult.
Therefore, there is a need in the art to develop an efficient, fully automatic, and accurate dismounting system and assembling method for automatically dismounting and assembling the graphite boat instead of manual assembly, thereby improving the automation degree of production, reducing the damage of the graphite boat due to the process, saving the production cost, and avoiding the harm of the production process to the body of the worker.
