Embodiment 1

[0042] This embodiment provides a packaging method for finished polysilicon rods, comprising the following steps:

[0043] (1) Wrap the finished polysilicon rod with a protective film;

[0044] (2) Set the sealing line for sealing on the organ bag, the grip buffer line for fixed buffering after folding, the distance between the grip buffer line and the opening of the organ bag is greater than the distance between the sealing line and the opening of the organ bag;

[0045] (3) packing the wrapped finished polysilicon rod into the organ bag;

[0046] (4) seal the organ bag by the sealing line of the organ bag;

[0047] (5) Fold along the edge buffer line to fix and buffer the finished polysilicon rod in the organ bag.

[0048] The packaging method of the finished polysilicon rod of the present embodiment has the following advantages:

[0049] 1. Reduce the damage loss of the packaging bag and the comprehensive loss during the packaging process of the finished polysilicon rod,...

Embodiment 2

[0056] Such as Figure 1~3 As shown, the present embodiment provides a packaging method for the finished polysilicon rod 11, comprising the following steps:

[0057] (1) The polysilicon rod 1 grown in the reduction furnace of the improved Siemens method CVD process is disassembled and then sent to the crushing process through an automatic transfer line, such as figure 1 As shown, a cylindrical tooling 3 is used on the clean work platform 4, and the polysilicon rod 1 is cut by the cutting device 2 to obtain the finished polysilicon rod 11, so that it meets the specification requirements of the packaging method in this embodiment. The finished polysilicon rod 11 is diameter L 1 , the length is L 2 . Specifically, the length L in this embodiment 2 =280±80mm, the mass M of a single finished polysilicon rod 11 1 It is 8-12kg.

[0058] (2) if figure 2 As shown in a, the air cushion film 8, the high-purity film 9, and the finished polysilicon rod 11 are sequentially placed on...

Embodiment 3

[0081] This embodiment provides a packaging method for finished polysilicon rods, the difference from Embodiment 2 is: the number of columns in the packing box is L 8 = 6, the number of layers in the packing box h 3 =5.

[0082] It should be noted that the diameter L of the finished polysilicon rod in this embodiment 1 , length L 2 , where L 2 =1.8×L 1 .

[0083] It should be noted that the thickness of the high-purity membrane in this example is 3 μm, the high-purity membrane is rectangular, and the size specification is the length L of the high-purity membrane 3 mm×high purity membrane width L 4 mm, where L 3 ≥ L 4 , L 3 =2.75×L 2 , L 4 =4.2×L 1 .

[0084] It should be noted that, in this embodiment, the air cushion film is rectangular, and the dimension specification is the length L of the air cushion film 5 mm×air cushion film width L 6 mm, L 6 =0.9L 4 .

[0085] It should be noted that in this embodiment, a backing board is installed between the inner la...

Abstract

The invention discloses a packaging method for finished polysilicon rods, which comprises the following steps: (1) wrapping the finished polysilicon rods with a protective film; Buffered gripping buffer line, the distance between the gripping buffer line and the opening of the organ bag is greater than the distance between the sealing line and the opening of the organ bag; (3) packing the wrapped finished polysilicon rods into the organ bag; (4) passing the organ bag The sealing line of the bag seals the organ bag; (5) folds along the edge buffer line to fix and buffer the finished polysilicon rod in the organ bag. The method reduces the damage loss of the packaging bag and the comprehensive loss during the packaging process of the finished polysilicon rod, and can reduce the packaging cost of the finished polysilicon rod by 20-30%; after the polysilicon rod is broken, the quality loss of the crushed material and powdered polysilicon during transportation is avoided 2 to 5%; since there is no need to carry out the crushing process of polycrystalline silicon rods, the high-purity quality of polycrystalline silicon is guaranteed.

Description

technical field [0001] The invention belongs to the technical field of polysilicon production, and in particular relates to a packaging method for finished polysilicon rods. Background technique [0002] At present, the main production method used in the polysilicon industry is the improved Siemens method. The polycrystalline silicon rods produced by the improved Siemens method are transported to the crushing process through the transfer line for processing. After the polycrystalline silicon rods are taken out of the transfer box, the rod-shaped polycrystalline silicon rod products are broken into block products on a specific platform. Polysilicon fragments are packed in certain one or two layers of regular plastic bags, weighed, sealed and packed into boxes. [0003] This traditional way of packaging polysilicon fragments is affected by the sharp edge of the silicon block. The packaging bag is easy to break during packaging, and the block material takes up a lot of space. ...
