CN-117120336-B - Clamp and manufacturing method of polysilicon box body

Abstract

The invention is used for preventing the local bulge of the containing bag in the process of lifting the bagged polycrystalline silicon and putting the bagged polycrystalline silicon into a set position, thereby accurately putting the containing bag into a set space. The storage box (10) includes a side body (11) forming an insertion space (12), the insertion space (12) being used for inserting a storage bag (B1) containing polysilicon (S1), a lifting part (13) for lifting the side body (11), and a receiving tray (15) for supporting the storage bag (B1), wherein when the receiving tray (15) is separated from a bottom (11 a) of the side body (11), an Opening (OP) is formed in the bottom of the side body (11), and a delivery path (30) for the storage bag (B1) is formed through the Opening (OP).

Description

Clamp and manufacturing method of polysilicon box body Technical Field The invention relates to a clamp for manufacturing a polysilicon boxing body and a manufacturing method of the polysilicon boxing body. Background Polycrystalline silicon used as a silicon semiconductor material, a solar cell material, or the like is manufactured in a rod shape, and then cut and crushed to be used as a raw material, thereby being processed into bulk polycrystalline silicon of a predetermined size. The bulk polysilicon is bagged in a predetermined amount and is packaged for shipment. Conventionally, as shown in patent document 1, the above-described bagging and boxing are generally performed manually. In the future, in order to improve the work efficiency and save labor, it is desired that the above-described bagging and boxing operations be automated. Prior art literature Patent literature Patent document 1 Japanese patent application laid-open No. 2017-512159 Disclosure of Invention Problems to be solved by the invention However, the above-described boxing automation has the following problems. The shape of the chunk polycrystalline silicon is irregular, and the fracture surface is angled and has sharp portions, so that the bag containing the chunk polycrystalline silicon is easily broken. In addition, when the upper portion of the bag containing a plurality of chunk polycrystalline silicon is lifted, the single chunk polycrystalline silicon inside the bag moves downward, and the width of the bag is locally enlarged. Therefore, the bag is likely to collide with a partition plate or the like of the box at the time of boxing, and there is a problem that the bag is likely to be broken at the collision portion. The present invention has been made in view of the above-described problems, and an object of the present invention is to prevent local bulging of a storage bag during lifting and putting the packaged polycrystalline silicon in a predetermined position, thereby accurately putting the storage bag in a predetermined space. Technical scheme for solving problems In order to solve the problems, one aspect of the invention relates to a clamp comprising a side body forming an interpolation space for interpolating a containing bag containing polysilicon, a lifting part arranged on the side body for lifting the side body, and a receiving tray detachably arranged at the bottom of the side body for supporting the containing bag, wherein when the side body is lifted, an opening part is formed at the bottom of the side body, and when the receiving tray is separated from the bottom of the side body, a throwing path of the containing bag from the interpolation space to the containing space is formed when the containing bag is thrown into the containing space containing the containing bag from the upper direction. In order to solve the above problems, a method for manufacturing a polysilicon casing according to an aspect of the present invention is a method for manufacturing a polysilicon casing by filling a container bag into a casing in which a containing space is formed using a jig, the method including a lifting step of lifting the container bag inserted in the jig together with the jig, and a throwing step of moving the lifted jig and the container bag to a position above a predetermined containing space and throwing the container bag into the containing space from the position above the containing space. Effects of the invention According to one aspect of the present invention, it is possible to prevent the partial bulge of the receiving bag during the process of lifting up and putting the bagged polysilicon to a predetermined position, thereby accurately putting the receiving bag into a predetermined space.
