Description

Technical Field

[0001] The utility model belongs to the technical field of glass sintering, and in particular relates to a relay tube shell glass sintering tool. Background Art

[0002] In the field of electronic devices, the development of relays is very rapid. From the traditional "direct plug-in" relays to the wide variety of relays today, the pin form, arrangement and tube shell structure of relays are becoming more and more diverse and complex. As a result, more stringent requirements are also put forward for the design of glass sintering tooling, which must ensure both the reliability of the tooling design and the convenience of tooling use.

[0003] like Figure 8 , 9 As shown, it is a flat relay, whose pins are no longer arranged on the base, but on both sides of the tube shell, and the pin structure is changed from straight plug-in type to bent type, and the end is flattened. If the traditional sintering method is still used, the sintering process cannot be implemented.

[0004] For example, the Chinese patent with publication number CN114543536A discloses a sintering device and sintering method for ceramic relay housing, wherein the sintering device includes a supporting portion, which is arranged between the end surface of the housing and the top surface of the sagger to provide support for the plane around the truncated cone on the end surface of the housing. However, the patent is for sintering the ceramic housing of the relay, and it is impossible to sinter the desired glass tube shell shape. At the same time, the pins and the housing are not sintered into one piece, and it is not suitable for sintering flat relay glass tube shells.

[0005] For example, the Chinese patent with publication number CN114543536A discloses a portable solid relay sintering fixture, including a mounting plate: a limit block is arranged on the upper side of the mounting plate, a positioning bracket is fixedly connected to the upper side of the right end of the mounting plate, a guide seat is arranged on the upper side of the positioning bracket, a positioning slide is slidably connected to the outer side of the guide seat, an adjusting screw is rotatably connected to the right side of the positioning slide, a solid relay is arranged on the upper side of the limit block, and the adjusting screw is threadedly connected to the positioning bracket. However, this patent is applicable to the sintering molding of the entire relay, on which a spring is arranged, but not applicable to the shell glass of the sintered relay, and there is no limit on the pins, and it is also not suitable for the shape of the sintered shell.

DETAILED DESCRIPTION

[0031] The technical solution of the utility model is further described below, but the scope of protection required is not limited to the description.

[0032] like Figure 1 , 2 As shown, a relay tube shell glass sintering tool includes a base plate 1, a positioning plate 2, a fixing plate 3, a pressing block 4 and a cover plate 5; the tube shell 20 is placed on the base plate 1, the fixing plate 3 is installed in the tube shell 20, the positioning plate 2 is connected to the fixing plate 3, the pressing block 4 is respectively connected to the positioning plate 2 and the fixing plate 3, and the cover plate 5 is connected to the pressing block 4.

[0033] During assembly, first insert the pin 18 and the glass embryo 19 into the tube shell 20, then flatten the pin 1, during which time pay attention to the protection of the glass embryo 19, and then put it as a whole on the bottom plate 1; install the positioning plate 2 and the fixing plate 3 into the tube shell 20 to position and fix the pin 18; then press the pressing block 4 onto the positioning plate 2 and the fixing plate 3, while fixing the pin 18 and limiting the tube shell 20; finally, press the cover plate 5 onto the pressing block 4, the cover plate 5 transmits the clamping force to the pressing block 4, and the pressing block 4 transmits the clamping force to the positioning plate 2 and the fixing plate 3, and cooperates with the bottom plate 1 to clamp the pin 18 and the tube shell 20, and make the contact between the pin 18 and the glass embryo 19 have lubricity.

[0034] like Figure 3 As shown, the bottom plate 1 is provided with a limiting hole A6, a limiting hole B7 and a positioning column 8.

[0035] The limiting hole A6 is used to limit the pin 18 at one end of the tube shell 20, and the limiting hole B7 is used to limit the pin 18 at the other end of the tube shell. A positioning hole is also provided on the tube shell 20, and the positioning column 8 is used to connect with the positioning hole; through the setting of the limiting hole A6, the limiting hole B7 and the positioning column 8, it is ensured that the pin 18 and the tube shell 20 are fixed in the expected position on the tooling.

[0036] The number of the limiting holes A6 and the limiting holes B7 needs to be set according to the number of the pins 18 .

[0037] like Figure 4 As shown, the positioning plate 2 is provided with an arc bayonet A9, and the pressing block 4 is provided with an arc bayonet B10, and the arc bayonet A9 and the arc bayonet B10 are connected and matched to form a limiting hole C.

[0039] The pin 18 is placed on the positioning plate 2 , and the arc snap-in A9 holds the position of the pin 18 . The arc snap-in B10 cooperates with the arc snap-in A9 to form a limiting hole C, which further limits the position of the pin 18 and ensures the wettability of the contact between the pin 18 and the glass embryo 19 .

[0040] like Figure 5 As shown, the fixing plate 3 is provided with a groove A11, and the pressing block 4 is provided with a groove B12, and the groove A11 and the groove B12 are connected and matched to form a flat pin groove.

[0041] Grooves A11 and B12 are connected and cooperated to form a flat pin groove, which is used to fix and limit the flattened pin 18, further ensuring the stability of the pin 18 on the sintering tooling, ensuring that the pin 18 can be in the expected position during sintering, and the flattened pin facilitates wire bonding.

[0042] like Figure 6 As shown, the fixing plate 3 is provided with a connecting strip 14 , the pressing block 4 is provided with a connecting groove 15 , and the connecting strip 14 and the connecting groove 15 are connected.

[0043] The connecting strip 14 and the connecting groove 15 are used to provide accurate positioning of the pressing block 4 when connecting the positioning plate 2 and the fixing plate 3, and to limit the position of the pressing block 4, thereby ensuring that the pressing block 4 is accurately positioned so that the limiting hole C and the flattened pin groove can be smoothly implemented.

[0044] The connecting bar 14 and the connecting groove 15 are provided with inclined surfaces, and the connecting bar 14 and the connecting groove 15 are connected via the inclined surfaces.

[0045] The inclined surface design facilitates installation while allowing the pressing force to be transmitted, ensuring that the pressing block 4 can press the fixing plate 3 .

[0049] The inclined surface design facilitates installation and enables the pressing force to be transmitted, ensuring that the cover plate 5 can press the pressing block 4 .

[0050] The base plate 1 , the positioning plate 2 , the fixing plate 3 , the pressing block 4 and the cover plate 5 are made of graphite.

[0051] Graphite has a high melting point and strong thermal conductivity, making it suitable for sintering tube and shell glass.

[0052] The sintering tool is provided with a bottom plate 1 and a cover plate 5 on both sides, and can be used with corresponding tooling fixtures to make the tooling modules fit tightly together. The whole device can be rotated 90 degrees to realize the glass sintering process in a horizontal state.
