Description

Technical Field

[0001] The utility model belongs to the technical field of ceramic filters, and particularly relates to a capping component for a plate filter. Background Art

[0002] Plate filters are widely used in connectors of electronic devices. Its structure usually consists of multiple hole electrodes and outer electrodes. These holes serve as the electrodes of the filter respectively, and a common electrode is arranged in a peripheral circle. During the manufacturing process, it is necessary to cap the internal holes to lead out the electrodes. The existing capping methods mainly include the following several kinds:

[0003] 1. Dip coating method:

[0004] Immerse the capacitor in the capping material to make the capping material penetrate into the product manufacturing groove, and then cure it by methods such as drying or sintering. This method is simple, but it is difficult to control the thickness of the capping layer and is prone to pore blockage.

[0005] 2. Spraying method:

[0006] Use a spray gun to spray the capping slurry into the product manufacturing groove. However, the existing size of the wire mesh holes is only 0.6 mm, and the size of the spray gun is much larger than the size of the holes, so it cannot reach in for spraying.

[0007] 3. Filling method:

[0008] Directly fill the end paste into the manufacturing groove, and then compact and cure it. This method is completely inapplicable to plate filters because the manufacturing groove needs to insert the needle head of the connector later, and it cannot be used after compaction and curing.

[0009] The main problems of the above methods and equipment will cause blockage of the internal manufacturing groove and uneven capping thickness, thus affecting the electrical performance of the filter. Therefore, there is an urgent need for a device that can effectively cap and does not block the voids.

[0010] The patent document with the publication number of CN211251680U discloses a screen printing device, which specifically relates to the technical field of screen printing. It includes a workbench, one side of the workbench is fixedly connected with a base, one side of the top of the base is fixedly connected with a moving plate, a cavity is opened inside the base, a second motor is fixedly connected to the bottom end inside the cavity, a first reciprocating lead screw is fixedly connected to the top of the second motor, and a feeding mechanism is arranged inside the moving plate. However, this setting lacks a vacuum adsorption function and cannot meet the preparation requirements of the filter. Content of the Utility Model

[0011] The utility model provides a capping component for a plate filter to solve the problems of pore blockage and uneven capping thickness existing in the prior art.

[0012] The utility model is achieved through the following technical solutions.

[0013] A terminal component of a plate filter provided by the utility model comprises a printed part, a placement table, a bottom plate and a filter.

One side of the placement table is connected to the printed part, and the other side of the placement table is connected to the bottom plate. The filter is connected to the bottom plate through a pipeline.

[0014] Preferably, slots, holes A and fixing columns are arranged on the placement table. The slots penetrate through the placement table, and the holes A are arranged at the four-corner edges of the placement table.

[0015] Preferably, grooves are respectively arranged at the four-corner edges of the slots. The fixing columns are perpendicular to the placement table, and the fixing columns are arranged in a triangular distribution around the slots.

[0016] Preferably, a plurality of slots are arranged symmetrically, and the size of the slots is smaller than the size of the inner cavity.

[0017] Preferably, holes B and holes C are arranged on the bottom plate. The holes B are arranged in the middle of the bottom plate, and the holes C are arranged at the four-corner edges of the bottom plate. The holes B on the bottom plate are connected to the filter through a pipeline.

Specific implementation mode

[0026] The technical solution of the present invention will be further described below, but the scope of protection claimed is not limited thereto.

[0027] Embodiment:

[0028] As Figure 1 shown, a capping component of a plate filter includes a printed part 1, a placement table 2, a bottom plate 3 and a filter 4. The printed part 1 includes an outer frame 11 and a screen part 12. The screen part 12 is arranged in the inner cavity 13 of the outer frame 11. The printed part 1 is a screen printing part. By adjusting the screen mesh number, the amount of end paste is controlled and printed into the slot 21. The mesh number of the screen part 12 can be adjusted to control the amount of printed paste. One side of the placement table 2 is connected to the printed part 1, and the other side of the placement table 2 is connected to the bottom plate 3. The filter 4 is connected to the bottom plate 3 through a pipe 5.

[0029] The placement table 2 is provided with a slot 21, a hole A22 and a fixing post 23. The slot 21 runs through the placement table 2. The hole A22 is arranged at the four - corner edges of the placement table 2. The fixing post 23 plays a role in positioning and guiding the installation of the printed part 1.

[0030] The four - corner edges of the slot 21 are respectively provided with grooves 24. The fixing post 23 is perpendicular to the placement table 2, and the fixing post 23 is arranged in a triangular distribution around the slot 21. The printed product is formed in the slot 21, and the design of the groove 24 facilitates the removal of the printed product from the slot 21.

[0031] A number of the slots 21 are arranged symmetrically. The size of the slot 21 is smaller than the size of the inner cavity 13 to avoid interference with the outer frame 11.

[0032] The bottom plate 3 is provided with a hole B31 and a hole C32. The hole B31 is arranged in the middle of the bottom plate 3. The hole C32 is arranged at the four - corner edges of the bottom plate 3. The hole B31 on the bottom plate 3 is connected to the filter 4 through a pipe 5, and the hole B31 is located below the slot 21. One side of the pipe 5 at the outlet end of the filter 4 is connected to a vacuum adsorption device. By adjusting the vacuum degree, the excess end paste is sucked out from the hole B31. The vacuum degree of the vacuum adsorption instrument can be adjusted to control the thickness of the end paste on the inner wall of the slot 21. The position and number of the holes C32 correspond to the holes A22. The placement table 2 can be fixed on the bottom plate 3 by passing a bolt through the hole A22 and then thread - connecting it with the hole B31.

[0033] A filter screen 41 is provided inside the filter 4 for filtering impurities and particles in the end paste. Threaded holes 42 are respectively provided at both ends of the inlet end and the outlet end of the filter 4, and both ends of the inlet end and the outlet end of the filter 4 are threadedly connected to the pipeline 5 through the threaded holes 42. This setting facilitates the disassembly of the filter 4 for replacement to avoid blockage of the filter.

[0034] Holes D14 are provided on the outer frame 11, and the holes D14 are arranged in a triangular distribution around the wire mesh member 12. The positions of the holes D14 correspond to the fixing columns 23, and the fixing columns 23 penetrate through the outer frame 11 through the holes D14, so that the printed part 1 is fixed on the placement table 2.

[0035] Adjust the vacuum degree and the aperture of the wire mesh member 12: According to the size of the holes and the viscosity of the end paste, determine the optimal vacuum degree and the wire mesh mesh number through experiments to ensure that a uniform sealing end layer is formed in the slot 21 without blocking the pores.

[0036] Operation process:

[0037] Start printing the printed part 1, uniformly print the end paste into the slot 21, and use vacuum adsorption to make the end paste flow uniformly down along the hole wall of the hole B31, suck out the excess end paste, and the excess end paste is recycled after passing through the filter 4.
