[0014] In order to make the purpose, technical solution and advantages of the utility model clearer, the technical solution of the utility model will be described in detail below. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other implementation methods obtained by ordinary technicians in this field without creative work belong to the scope of protection of the utility model.

[0015] like Figure 1 and Figure 2 As shown, the utility model is a tooling for assisting the sintering of multiple sheets in a tube furnace, which is an auxiliary tooling 2 arranged in a furnace tube 1, and the auxiliary tooling 2 includes a top plate 21, a support rod 22, and a bottom plate 23. A positioning hole 24 is opened on the top plate 21, which is a through hole; a fixing pit 25 is opened on the bottom plate 23, which is a non-penetrating pit, and the positioning hole 24 is aligned with the fixing pit 25 in the normal direction. The auxiliary tooling 2 also includes a wafer carrier tube 3 arranged between the top plate 21 and the bottom plate 23.

[0016] The apertures and number of the top plate 21 and the bottom plate 23 are determined by the diameter and number of the sintered sheets and the furnace tube 1 of the tube furnace.

[0017] In this embodiment, there are four support rods 22, which are evenly and vertically arranged between the top plate 21 and the bottom plate 23. The length of the support rods 22 is determined by the length of the wafer tube 3, and further by the thickness and number of the sintered sheets filled therein.

[0018] The interior of the wafer tube 3 is used to carry sheets pressed from the material to be sintered. The wafer tube 3 is arranged between the corresponding positioning hole 24 and the fixing pit 25 . The length of the wafer tube 3 is greater than the distance between the top plate 21 and the bottom plate 23 .

[0019] The auxiliary tooling 2 of the present invention is made of materials that can withstand sintering temperatures, such as quartz, ceramics, aluminum alloys, and the like.

[0020] The utility model is used for assisting the sintering of multiple pieces in a tubular furnace. The specific process when in use is as follows:

[0021] After the material to be sintered is pressed into a sheet of fixed diameter by a tablet press, it is loaded into the wafer tube 3. After the sheet is filled to about 70%, the wafer tube 3 is opened toward the bottom plate 23, inserted into the auxiliary tooling 2 through the positioning hole 24 on the top plate 21, and the tube mouth is inserted into the fixed pit 25. Similarly, according to actual needs, the filled sheet wafer tube 3 is filled into the auxiliary tooling 2, and finally the entire auxiliary tooling 2 is pushed into the constant temperature part of the furnace tube 1 of the tube furnace for sintering. After sintering is completed, the auxiliary tooling 2 is pushed out as a whole from the other end to obtain the sintered material.

[0022] Through the technical solution of the utility model, the space utilization rate of the tubular furnace is greatly improved, and a large number of sheets can be sintered at one time; the structure is simple, and feeding and discharging are very convenient; it exists in the form of small units, and multiple combinations can be made according to actual needs or the number of wafer carriers can be reduced, the quantity is flexible, and the preparation efficiency is improved.

[0023] The above is only a specific implementation of the utility model, but the protection scope of the utility model is not limited thereto. Any technician familiar with the technical field can easily think of changes or substitutions within the technical scope disclosed by the utility model, which should be included in the protection scope of the utility model. Therefore, the protection scope of the utility model should be based on the protection scope of the claims.
