Example 1
Fig. 1 is a schematic structural view of a single crystal silicon rod head and tail material transfer device of the utility model. FIG. 2 is a schematic cross-sectional view of a single crystal silicon rod head and tail transfer device of the present utility model.
As shown in fig. 1, the single crystal silicon rod head and tail material transfer device comprises a material placing part 1, a frame 2, wheels 3 and handrails 4. The device can well collect and transfer irregular monocrystalline silicon rod head and tail materials 5 (hereinafter referred to as head and tail materials 5) to the next process, and meanwhile, the sharp part of the head and tail materials 5 can be prevented from scratching workers.
The carriage 2 includes a top plate 21, a base 22, support columns 23, and side frames 24. One end of the top plate 21 is connected to one end of the base 22 via a plurality of support columns 23, and the other end of the top plate 21 is connected to the other end of the base 22 via a side frame 24. The top plate 21 is horizontally arranged, the top plate 21 and the base 22 are relatively parallel, and the plurality of support columns 23 and the side frames 24 are respectively perpendicular to the base 22, so that a hollow bracket is formed. The top plate 21 is a rectangular plate, the base 22 is a hollow plate structure, and specifically, grooves are formed on four sides of the plate to form a hollow plate structure with hollow periphery. The vertical height of the side frame 24 is higher than the height of the support column 23, that is, the side frame 24 is higher than the top plate 21, and a space with an L-shaped cross section between the raised portion and the top plate 21 is used for placing the material placing section 1. The frame 2 may be made of stainless steel.
As shown in fig. 1 and 2, the material placing part 1 comprises a cover plate 11 and side plates 12, wherein four side plates 12 enclose a rectangular space, and the cover plate 11 is positioned at the top of the rectangular space, so that a rectangular box-shaped structure is integrally formed. The cover plate 11 is provided with a plurality of circular holes, a plurality of mutually independent grooves 13 are formed in the circular holes and the rectangular space, the grooves 13 are arranged in an array, and the depth h 1 of the grooves 13 is the same as the height h 2 of the side plate 12 and is used for inversely placing the head and tail materials 5. Because the head and tail materials 5 are conical and irregular, if the head and tail materials are positively placed, sharp parts of the head and tail materials can scratch a transferring person in the transferring process, and meanwhile, the head and tail materials are easy to collide in the transferring process, so that unnecessary loss is caused. Thus, the head and tail stock 5 is placed upside down in the cylindrical recess 13. The diameter D 1 of the groove 13 is smaller than the bottom diameter D 2 of the head and tail stock 5 (i.e. the maximum diameter of the head and tail stock 5). The depth h 1 of the groove 13 is larger than or equal to the depth h 3 of the head and tail materials 5 placed in the groove 13, namely, the head and tail materials 5 are partially inverted in the groove 13. Thus, not only can the scratch of the transfer personnel be prevented, but also the transfer device can be suitable for transferring the head and tail materials 5 with different sizes. The number of grooves 13 may be set according to actual requirements. In the present embodiment, the cover plate 11 is provided as a tetrafluoro plate; the side plate 12 is a double-layer plate structure with a stainless steel plate externally coated with a tetrafluoro plate. The arrangement of the tetrafluoro plate can effectively avoid the contact of the head and tail materials 5 of the monocrystalline silicon rod with metal, and reduce the workload of the rear-end working procedure.
The wheels 3 are arranged at the bottom of the frame 2, which may be directional wheels or universal wheels.
The armrests 4 are obliquely arranged at the top of the side frames 24, so that the head and tail materials 5 can be conveniently transported.
The present utility model is not limited to the above-described embodiments, and any modifications, improvements, substitutions, and the like, which may occur to those skilled in the art, fall within the scope of the present utility model without departing from the spirit of the utility model.
