Description

Technical Field

[0001] The utility model relates to the technical field of silicon core production, in particular to a silicon core packaging platform. Background Art

[0002] With the continuous update and iteration of the photovoltaic industry, the demand for the main raw material of photovoltaic, "high-purity crystalline silicon", is gradually increasing. A carrier called silicon core is used in the production of high-purity crystalline silicon rods. Through the reduction process, high-purity trichlorosilane grows on the silicon core carrier, and finally high-purity crystalline silicon is obtained. To improve the product quality and growth rate of pure crystalline silicon, the previous square silicon cores are currently being transformed into round silicon cores.

[0003] The square silicon core is mainly cut from a round bar of the Czochralski silicon core. The four sides of the cross-section are equal, and the four cutting surfaces are flat, so it can be quickly stacked. When packaging and evacuating, there is no need to consider the impact of the evacuation time on the fracture of the silicon core. Although the transformed round silicon core is superior to the square silicon core in terms of growth efficiency and processing efficiency, due to the irregular arc surface on the surface of the round silicon core, it cannot be quickly and neatly stacked during packaging, seriously affecting the packaging efficiency, and the silicon core is prone to fracture during the packaging process.

The horizontal parts of the two temporary storage racks 3 are arranged parallel to each other, and the distance between the two temporary storage racks 3 is not greater than the length of the silicon core. The number of temporary storage racks 3 in the temporary storage unit can be more than two. The multiple temporary storage racks 3 are arranged in a straight-line track, and the distance between the temporary storage racks 3 at both ends of the arrangement track is not greater than the length of the silicon core.

[0035] The sub-packaging unit is arranged on the side of the temporary storage unit. The sub-packaging unit includes two sub-packaging racks 4. The sub-packaging rack 4 includes a bottom plate 41 horizontally arranged above the table 1. On the bottom plate 41, a plurality of vertically arranged side plates 42 are provided. The plurality of side plates 42 are arranged parallel to each other at equal intervals on the bottom plate 41, and a U-shaped sub-packaging groove is formed between the two side plates 42. A U-shaped connecting support plate 43 is provided below the bottom plate 41, and the connecting support plate 43 is connected to the table 1. The bottom plates 41 of the two sub-packaging racks 4 are arranged parallel to each other. The arrangement track of the two sub-packaging racks 4 is parallel to the arrangement track of the two temporary storage racks 3, and the side plates 42 of the sub-packaging rack 4 are parallel to the vertical parts of the temporary storage rack 3.

[0036] The distance between the two sub-packaging racks 4 is less than the length of the silicon core. After the silicon core is placed on the two sub-packaging racks 4, both ends of the silicon core can respectively extend out of the two sub-packaging racks 4 by a certain length, which is convenient for winding films on both ends of the silicon core. The number of sub-packaging racks 4 in the sub-packaging unit can also be more than two. The multiple sub-packaging racks 4 are arranged in a straight-line track and parallel to the arrangement track of the multiple temporary storage racks 3. The distance between the two sub-packaging racks 4 at both ends of the arrangement track of the multiple sub-packaging racks 4 still needs to satisfy being less than the length of the silicon core.

[0037] The bagging unit is arranged on the side of the sub-packaging unit away from the temporary storage unit. The bagging unit includes two bagging end frames. A bagging bracket 2 is arranged between the two bagging end frames. The two bagging end frames and the bagging bracket 2 are arranged in a straight-line track and parallel to the arrangement track of the multiple sub-packaging racks 4 and the multiple temporary storage racks 3.

[0038] Both the bagging end frames and the bagging bracket 2 are in a U shape. End rollers 5 are rotatably arranged on the bagging end frames, and support rollers 6 are rotatably arranged on the bagging bracket 2. The rotation axes of the end rollers 5 and the support rollers 6 are both horizontal and perpendicular to the arrangement track of the two bagging end frames and the bagging bracket 2. The two end rollers 5 are arranged at the same height. The support roller 6 is 15 - 20 mm higher than the two end rollers 5. The distance between the two end rollers 5 is not greater than the length of the silicon core.

[0039] The tabletop of the table 1 is provided with a table board made of tetrafluoro (polytetrafluoroethylene) material. The temporary storage rack 3, the sub-packaging rack 4, the end rollers 5 and the support rollers 6 are all made of tetrafluoro material to avoid secondary pollution when the silicon core contacts these components.

[0040] When packaging the silicon core, first confirm the placement position of the cleaned silicon core flower basket, specify the flower basket placement area, place the silicon core packaging platform in the flower basket placement area, quickly take out the cleaned silicon core in the flower basket, place a part of the silicon core on the sub-packaging rack 4, and place another part of the silicon core on the temporary storage rack 3. After taking out all the silicon cores in the flower basket, place the empty flower basket on the return basket line for flower basket reflux. Cover the two ends of the silicon core on the sub-packaging rack 4 with short PE (polyethylene) bags, and then continuously wrap 3 - 4 layers with oil-free winding film. Take out the silicon core from the sub-packaging rack 4 and place it on the support roller 6. Utilize the height difference between the support roller 6 and the two side end rollers 5 to lift one end of the silicon core to make it inclined. The middle part of the silicon core contacts the support roller 6, the lower end of the silicon core contacts the corresponding lower end roller 5, and there is a certain distance between the higher end of the silicon core and the corresponding lower end roller 5. Quickly put a PE packaging bag on the higher end of the silicon core, and then pull the bag mouth of the PE packaging bag towards the lower end of the silicon core. When the bag mouth of the PE packaging bag is pulled to the support roller 6, lift the lower end of the silicon core, the silicon core swings around the support roller 6, the higher end of the silicon core descends and contacts the lower end roller 5 below, and after the middle part of the silicon core disengages from the support roller 6, quickly pull the bag mouth of the PE packaging bag and put the whole silicon core inside. The PE packaging bag is evacuated for a period of time, and the evacuated silicon core is placed on the silicon core transfer mobile table.
