Problems solved by technology

[0004] The present invention intends to provide a silver paste spraying process on the surface of the filter to solve the problem that in the prior art, after the entire surface of the silver paste is sprayed, it is then dried and sintered, and the silver paste will be scratched if the silver paste is not completely deposited. In this case, re-spraying is required in the follow-up, which leads to the problem that the entire process takes a long time

Embodiment 1

[0042] The silver paste spraying process on the surface of the filter uses a jig for spraying the filter to realize the spraying of the silver paste. The jig for spraying the filter includes a rack 1, a counterweight bar 8, and a plurality of first installation bars 2 and second installation bars 3. The third installation article 4. The storage rack 1 is rectangular, and the storage rack 1 is formed by sequentially connecting four storage strips. Handles 5 are fixed on the upper and lower two storage bars, and the handles 5 are rectangular, which is convenient for holding.

[0043] The bottom of the storage rack 1 is provided with several support bars 6 crosswise. In this embodiment, there are 8 support bars 6, and 6 support bars 6 are arranged horizontally, and the other 2 support bars 6 are arranged vertically. The set support bar 6 is vertical; a collecting plate 7 is placed on the support bar 6 . The size of the collecting plate 7 is consistent with the size of the insid...

Embodiment 2

[0070] Embodiment 2 differs from Embodiment 1 only in that, as image 3 As shown, the flexible adjusting member in this embodiment includes a positioning block 16 and an adjusting block 19 , and the adjusting block 19 is located between the positioning block 16 and the blocking block 13 . The right side of the adjustment block 19 is also rotatably connected with an adjustment rod 20, the adjustment rod 20 runs through the positioning block 16, and the adjustment rod 20 is threaded with the positioning block 16, and the right end of the adjustment rod 20 is fixed with a rotating block.

[0071] The right end of the adjusting block 19 is also fixed with a sliding rod 22 , the sliding rod 22 is rectangular, and the positioning block 16 is provided with a sliding slot 23 for the sliding rod 22 to slide. The left side of the adjustment block 19 is provided with a flexible layer, the flexible layer is a rubber layer, a silica gel layer or a latex layer, and a 5mm thick rubber layer ...

Embodiment 3

[0074] The only difference between embodiment 3 and embodiment 1 is that in this embodiment, there is also a positioning piece for fixing the first installation strip 2, the second installation strip 3 or the third installation strip 4 on the left side during spraying ,like Figure 4 As shown, the positioning member includes a first magnetic block 25 and a second magnetic block 26 , and the first magnetic block 25 and the second magnetic block 26 repel each other. There are two positioning parts, and they are respectively located in the upper and lower storage strips (that is, the storage strips matched with the groove 9). A first magnetic block 25 is embedded in the first installation bar 2 , the second installation bar 3 and the third installation bar 4 .

[0075] The left ends of the upper and lower two storage bars are provided with cavities 27, vertically slidingly connected with an inverted conical block 28 in the cavity 27, and a spring is welded between the bottom of ...

Abstract

The invention belongs to the technical field of technology for spraying silver paste on the surface of waveguides or resonators, transmission lines or other waveguide devices, and discloses a silver paste spraying process on the surface of a filter. Spray silver paste on the plane, dry and sinter after spraying to obtain a semi-finished product; then spray silver paste on the remaining facade, side, and plane of the ceramic blank in turn, dry and sinter after spraying to obtain a finished product. The present invention solves the problem that in the prior art, after the surface of the entire silver paste is sprayed, it is then dried and sintered, and the silver paste is not completely deposited, it will be scratched, so that follow-up re-spraying is required, resulting in the failure of the entire process. The problem of the process taking a long time.

Description

technical field [0001] The invention belongs to the technological field of spraying silver paste on the surface of waveguides or resonators, transmission lines or other waveguide devices, and in particular relates to a silver paste spraying process on the surface of a filter. Background technique [0002] With the rapid development of 5G communication technology, microwave dielectric ceramic filters have gradually replaced traditional metal cavity filters in the field of 5G communication base stations due to their excellent characteristics of high dielectric constant, small frequency temperature coefficient, low loss, and miniaturization. The scale is getting bigger and bigger. In the composition structure of the microwave dielectric ceramic filter, the silver paste used for metallization accounts for a large proportion, so the silver paste needs to be sprayed on the ceramic blank during preparation. When spraying silver paste at present, first arrange the ceramic blanks on...
