The germanium ingot charging tool comprises two sleeve heads, each sleeve head comprises a shell, the shell is hollow, an opening is formed in at least one side in the left-right direction, and the two sleeve heads are used for sleeving one end of the germanium ingot through the respective openings for furnace charging and carrying. According to the germanium ingot charging tool, the two sleeve heads are used for sleeving one end of the germanium ingot (that is, the germanium ingot is corroded and ready to be charged) through the openings of the two sleeve heads, and whether an operator holds the two sleeve heads with hands or holds the middle of the germanium ingot with hands by wearing hundred-grade clean gloves, the two ends of the germanium ingot are protected by the two sleeve heads all the time; even if the two ends of the germanium ingot collide with external objects in the process of transferring the germanium ingot to a graphite boat (namely during charging and transferring), the two ends of the germanium ingot cannot be damaged by collision due to protection of the two sleeve heads, and external impurities cannot be introduced due to collision.

Description

TECHNICAL FIELD

[0001] The present disclosure relates to the field of germanium materials, and more particularly to a germanium ingot furnace loading tool. BACKGROUND

[0002] Before high-purity germanium polycrystal zone melting, the raw material germanium ingot needs to be subjected to etching treatment, such as Chinese patent document CN113718257A published on November 30, 2021. After the germanium ingot is etched, it can be loaded into the furnace, that is, the operator wears a hundred-level clean glove on both hands, transfers the germanium ingot to a graphite boat, then loads the graphite boat into a quartz tube with a movable zone melting heater outside, and finally installs a sealing flange with an air inlet at both ends of the quartz tube and a sealing flange with an air outlet, thus completing the germanium ingot loading operation.

[0003] In the process of transferring the germanium ingot to the graphite boat, the operator wears a hundred-level clean glove on both hands and holds the germanium ingot with his hands. However, since the usual holding position is usually in the middle of the germanium ingot, when the two ends of the germanium ingot collide with external objects, the two ends of the germanium ingot are easily damaged due to the hard and brittle nature of germanium. On the one hand, this will damage the germanium ingot raw material. On the other hand, the collision will introduce external impurities.

[0004] In addition, although the operator wears a hundred-level clean glove on both hands, impurities from the hundred-level clean glove will also be left on the surface of the germanium ingot during contact with the germanium ingot, which is not conducive to improving the product quality of high-purity germanium polycrystal zone melting. CONTENT OF THE UTILITY MODEL

[0005] In view of the problems in the background art, an object of the present disclosure is to provide a germanium ingot furnace loading tool that can avoid damage to the two ends of the germanium ingot during furnace loading transfer and will not introduce external impurities due to collision.

[0006] Thus, a germanium ingot furnace loading tool is provided, which includes two sleeve heads; each sleeve head includes a shell, the shell is hollow and has an opening on at least one side in the left-right direction, and the two sleeve heads are used to sleeve one end of the germanium ingot through the respective openings for furnace loading and handling.

[0007] The beneficial effects of the present disclosure are as follows: in the germanium ingot furnace loading tool according to the present disclosure, by sleeving one end of the germanium ingot (i.e., the germanium ingot has been etched and is ready for furnace loading) through the respective openings of the two sleeve heads, the operator can hold the two sleeve heads with his hands or hold the middle of the germanium ingot with his hands wearing a hundred-level clean glove. Regardless of the method, the two ends of the germanium ingot are always protected by the two sleeve heads. Even if the two ends of the germanium ingot collide with external objects during the transfer to the graphite boat (i.e., during the furnace loading transfer), due to the protection of the two sleeve heads, the two ends of the germanium ingot will not be damaged due to the collision, and external impurities will not be introduced due to the collision.

[0018] The accompanying drawings illustrate embodiments of the present disclosure and, as such, should be considered part of this disclosure. It is to be understood, however, that the disclosed embodiments are merely examples, and that the disclosure can be practiced in various forms. Therefore, specific details disclosed herein are not to be interpreted as limiting, but merely as a basis for the claims and as a representative basis for teaching one skilled in the art to variously employ the present disclosure in virtually any similarly purposed system. It will be apparent to those skilled in the art, upon attaching importance to the appended claims, that numerous changes can be made within the scope of the present disclosure and that equivalents can be substituted without departing from the true spirit and scope of the disclosure. Thus, it is intended that the disclosure fall not within the limitation of the disclosed embodiments, but within the scope of the claims.

[0019] Referring to Figures 1 to 3 , the germanium ingot loading tool 100 according to the present disclosure comprises two sleeves 1. Each sleeve 1 comprises a housing 11, which is hollow and has an opening 111 at least on one side in the left-right direction D2, and the two sleeves 1 are used to sleeve one end of a germanium ingot 200 via the respective openings 111 for loading and carrying.

[0020] In the germanium ingot loading tool 100 according to the present disclosure, by using the two sleeves 1 to sleeve one end of the germanium ingot 200 (i.e. the germanium ingot 200 has been prepared for loading after etching treatment), no matter whether the operator holds the two sleeves 1 by hand or grips the middle of the germanium ingot 200 by hand while wearing a hundred-level clean glove, the two ends of the germanium ingot 200 are always protected by the two sleeves 1, and even if the two ends of the germanium ingot 200 collide with external objects during the transfer to the graphite boat (i.e. during the loading transfer), due to the protection of the two sleeves 1, the two ends of the germanium ingot 200 will not be damaged by the collision, nor will external impurities be introduced by the collision.

[0021] As Figures 1 to 3As shown in the figure, in an example, each sleeve 1 further comprises a handle 12 extending upwardly from the top surface of the sleeve 1 in the upward-downward direction D3, the handle 12 is used for the operator to grip. Through the design of the handle 12, the operator only needs to directly grip the handle 12 of the two sleeves 1 with both hands respectively, so as to lift the germanium ingot 200 for transfer to the graphite boat, which improves the convenience of the operation of lifting the germanium ingot 200. For example, the handle 12 is cylindrical.

[0022] As shown in the figure, Figures 1 to 3 In an example, each sleeve 1 further comprises a stop disc 13, the diameter of the stop disc 13 is larger than that of the handle 12, the stop disc 13 is connected to the top of the handle 12, and the stop disc 13 is used to provide a hand stop when the operator grips the handle 12. Through the provision of the stop disc 13, when the operator grips the handle 12 with his hand, the hand is stopped, so that the hand will not slip off the handle 12.

[0023] As shown in the figure, Figures 1 to 3 In an example, the shell 11 is provided with an observation window 112, the observation window 112 is opened on at least one side wall of the shell 11 facing the operator in the front-rear direction D1, and the observation window 112 is used for the operator to observe the condition that one end of the germanium ingot 200 extends into the shell 11. In this way, it can be ensured that the one end of the germanium ingot 200 extends into the shell 11 for a sufficient length, avoiding the one end of the germanium ingot 200 from falling out of the shell 11 during the transfer process. Further, the observation window 112 is two, and the two observation windows 112 are respectively provided on the two side walls of the shell 11 in the front-rear direction D1. In this way, the use of the two sleeves 1 is not limited by the direction.

[0024] As shown in the figure, Figures 1 to 3 In an example, the other side of each shell 11 opposite to the side with the opening 111 in the left-right direction D2 is closed. In this way, after the two sleeves 1 are respectively sleeved on one end of the germanium ingot 200, the germanium ingot 200 will not slip out from the direction in which the opposite two ends of the germanium ingot 200 extend.

[0025] In order to simplify the design and manufacture of the sleeve 1, in an example, the two sleeves 1 are the same in shape and size.

[0026] In an example, each sleeve 1 is a polypropylene sleeve or a polytetrafluoroethylene sleeve. In this way, the components (i.e. the sleeves 1) in contact with the germanium ingot 200 will cancel the use of the hundred-level clean gloves, so that there is no background technology impurity residue from the hundred-level clean gloves in the process of contacting the germanium ingot 200.

[0027] Referring to Figure 2In one example, the germanium ingot loading fixture 100 further comprises a clamp 2 for clamping one end of the germanium ingot 200 into the corresponding sleeve 1, the clamp 2 being a polypropylene sleeve clamp or a polytetrafluoroethylene clamp. Likewise, components that come into contact with the germanium ingot 200 will be decontaminated using a hundred level clean glove so that there is no background contamination from the glove during the process of contacting the germanium ingot 200.

[0028] A number of example embodiments have been described above with the detail required to understand the various features of the embodiments. However, no limitation is intended to the combinations explicitly disclosed. Thus, the various features disclosed herein can be combined in any combination, unless otherwise indicated, to form additional combinations not explicitly disclosed.
