[0002] Ceramic splitter, also known as porcelain nozzle, capillary, as a welding needle of bonding machine, is suitable for welding of LED, IC chip, diode, triode, thyristor, surface acoustic wave and other circuits. Ceramic splitter has high hardness, high specific gravity, fine grain, high surface finish, high dimensional accuracy and good insulation. It is an axisymmetric ceramic tool with vertical holes and belongs to precision microstructure ceramic parts.

[0003] When the ceramic splitter embryo is sintered, a sagger is needed for storage and transportation. In order to prevent the circular ceramic embryo from rolling and being damaged in the sagger, the prior art provides a sagger suitable for sintering valve core ceramic parts, such as the public document with the publication number CN220062606U. The bottom of the sagger is recessed from one end to the other end to form a plurality of bearing grooves for the ceramic embryos to be placed side by side. The bearing grooves are arc-shaped grooves that gradually expand from the bottom to the top, so that the two sides of the bottom of the sagger are curved and undulating. However, in the public document, the sagger frame is a rectangular vertical frame structure, with two long frame sides arranged oppositely on both sides and two short frame sides arranged oppositely at both ends. The long frame side and the short frame side are formed with a connection area for the bottom of the sagger to be connected at the bottom of the side facing the bottom of the sagger. The sagger is integrally formed, and the volume of the ceramic splitter is small. The sagger is not conducive to the removal and placement of the ceramic splitter, and it will collide with the side of the sagger and be damaged during the removal and placement process.

[0006] In an practicable manner, a plurality of grooves are arranged on the surface of the sagger base located inside the frame, the grooves are parallel to each other and to the long side ribs; the bottom surface of the grooves fits with the side surface of the ceramic splitting knife blank.

[0007] In an practicable manner, the depth of the groove is greater than 1 mm and is less than or equal to the radius of the ceramic splitting knife blank; the spacing between the grooves is greater than 2 mm and less than the radius of the ceramic splitting knife blank.

[0008] In an practicable manner, several rows of ceramic splitting knife blanks are evenly placed on the sagger base, and the rows are aligned in such a way that the tip and flat end of the ceramic splitting knife blanks are aligned; each row of ceramic splitting knife blanks is provided with a maximum of six layers, and the number of ceramic splitting knife blanks arranged in the bottom layer is greater than the number of ceramic splitting knife blanks arranged in the top layer, so that the side of each row of ceramic splitting knife blanks is a trapezoid.

[0009] In an practicable manner, a cover body is arranged above the ceramic splitting knife blank, and the cover body is located in the frame body.

[0010] The second technical solution: a sagger assembly for sintering a ceramic splitter blank, comprising any one of the saggers for sintering a ceramic splitter blank in the first technical solution, wherein the saggers are stacked by a connection structure arranged on the long side ribs. In the present application, the connection structure may be in close contact.

[0011] In an practicable manner, the connection structure includes a male portion, which is located below the lower portion of the long side rib and the base of the sagger, and has a chamfer formed on the outer side;

[0012] The female part is located on the upper part of the long side rib, and a plane and an upward inclined surface are formed on the upper surface of the long side rib. The inclined surface and the chamfer cooperate with each other to realize the stacking of the saggers.

[0013] In an practicable manner, the top sagger is provided with a male cover, and the male cover has a fitting portion that fits with the female portion and an opening and closing portion that is easy to open and close.

[0014] In an practicable manner, at most four layers of ceramic splitting knife blanks are arranged in the sagger with the male cover.

[0015] Compared with the prior art, the utility model has the following beneficial effects:

[0016] The short side ribs of the present application are detachable and located in the axial direction of the groove, so that the ceramic splitting knife blank can be placed along a path parallel to the long side ribs without any contact with the sagger during the process, thereby protecting the integrity of the ceramic splitting knife blank.

[0017] The size of the grooves and the size of the grooves are to ensure that there is enough space in the sagger to realize the flow of hot air during sintering. The spliced ​​structure can also allow the gas generated in the sagger to flow out from the spliced ​​gap, which is conducive to the formation of the ceramic splitting knife blank. The placement of the ceramic splitting knife blank can prevent the ceramic splitting knife blank from moving in the sagger.

[0018] The design of the sagger combination enables sintering of multiple saggers at one time. The public part is also used for placing a single sagger, and the sagger base and the placement table below are placed at an interval to facilitate operation. The sagger can also be fixed in the sintering chamber through the public part. BRIEF DESCRIPTION OF THE DRAWINGS
