Description

Technical Field

[0002] In order to improve the high-frequency characteristics of the two-terminal capacitor, the shape of the capacitor is improved to obtain a three-terminal capacitor. The three-terminal capacitor is grounded at both ends of the chip, the dielectric is clamped, and the through-electrode and the ground electrode are alternately stacked, thus forming a structure similar to a through-core capacitor. The inductance of the through-electrode is the same as the inductance of the lead-type three-terminal capacitor, and can play a role similar to the inductance of the T-type filter, thereby reducing the influence of residual inductance. In addition, since the ground terminal connection distance of the three-terminal capacitor is short, the inductance of the ground terminal is very small, and the ground terminal of the three-terminal capacitor is connected to both ends in a parallel connection state, the inductance will also be reduced by half.

[0027] In order to explain the technical content, structural features, achieved objectives and effects of the present invention in detail, the following is a detailed description in conjunction with the implementation methods and the accompanying drawings.

[0028] See also Figures 1 to 4 The present invention discloses a three-terminal capacitor termination device, wherein the surface 11 of the three-terminal capacitor 1 is provided with an electrode 12, and the device comprises: a slurry plate 2, a slurry mechanism 3 and a fixing member 4, wherein the slurry plate 2 is provided with through holes 21 arranged in an array, wherein the through holes 21 are used to accommodate the three-terminal capacitor 1 and expose the surface 11 of the three-terminal capacitor 1 provided with the electrode 12; the fixing member 4 is detachably arranged on any surface of the slurry plate 2, and the fixing member 4 is used to fix the three-terminal capacitor 1 on the through hole 21; the slurry mechanism 3 comprises a slurry platform 31 and a slurry scraping member 32, wherein the slurry platform 31 is provided with end slurry, and the slurry scraping member 32 is provided with a plurality of openings 321 at intervals, wherein the openings 321 are used to shape the end slurry, and the slurry scraping member 32 is used to shape the end slurry into a plurality of strip-shaped end slurries 311, and the slurry plate 2 is configured to approach the slurry platform 31 so that the surface 11 of each three-terminal capacitor 1 arranged in a column direction or in a row direction provided with the electrode 12 contacts the strip-shaped end slurry 311.

[0029] The present invention includes a slurry plate 2, a slurry mechanism 3 and a fixing member 4, and a three-terminal capacitor 1 is introduced into a through hole 21 of the slurry plate 2 so that the three-terminal capacitor 1 can be neatly arranged on the slurry plate 2 and fixed by the fixing member 4, and then a slurry scraper 32 is used to shape the end slurry on the slurry platform 31 into a strip end slurry 311, and the slurry plate 2 is moved close to the slurry platform 31 so that the surface 11 of each three-terminal capacitor 1 arranged in the column direction or in the row direction, which is provided with an electrode 12, contacts the strip end slurry 311. The above-mentioned end-sealing device is adapted to the electrode structure of the three-terminal capacitor 1, and can perform an end-sealing operation on the three-terminal capacitor 1, which is conducive to improving the overall end-sealing efficiency and end-sealing effect of the three-terminal capacitor 1.

[0030] See also Figures 1 to 4The width of the opening 321 is smaller than the width of the surface 11 of the three-terminal capacitor 1 on which the electrode 12 is provided, which is beneficial to avoid a connection between the electrodes of the three-terminal capacitor 1 and cause a short circuit.

[0031] Specifically, in the present embodiment, the three-terminal capacitor 1 is a three-terminal chip multilayer ceramic capacitor (MLCC), and the end surfaces at both ends of the three-terminal capacitor 1 are respectively provided with through electrodes 121, and the middle position of the surface 11 of the three-terminal capacitor 1 is provided with a ground electrode 122, but not limited thereto. Since the opening 321 is used to shape the terminal paste, the width of the opening 321 determines the width of the strip terminal paste 311, and the width of the strip terminal paste 311 is smaller than the width of the surface 11 of the three-terminal capacitor 1 provided with the ground electrode 122, so that the terminal paste is applied to a specific position in the middle of the surface 11 of the three-terminal capacitor, which is beneficial to saving terminal paste material and ensuring the sealing effect of the ground electrode 122.

[0032] See also Figures 1 to 4 The through hole 21 is rectangular, and the size of the through hole 21 is greater than or equal to the size of the surface 11 of the three-terminal capacitor 1 on which the electrode 12 is provided, which is conducive to the three-terminal capacitor 1 being accommodated in the through hole 21 in the correct direction so that the surface 11 of the three-terminal capacitor 1 on which the electrode 12 is provided faces outward.

[0033] Specifically, in this embodiment, since the through electrodes 121 at both ends of the three-terminal capacitor 1 accommodated in the through hole 21 have been sealed, the size of the through hole 21 is slightly larger than the size of the surface 11 of the three-terminal capacitor 1 on which the electrode 12 is provided, and is adapted to the size of the surface 11 of the three-terminal capacitor 1 on which the electrode 12 is provided, but is not limited to this, and the shape of the through hole 21 is not limited to a rectangle.

[0034] See also Figures 1 to 4 , the spacing between two adjacent openings 321 is the same as the spacing between two through holes 21 arranged along the row direction; but not limited to this, for example, in some embodiments, the spacing between two adjacent openings 321 is the same as the spacing between two through holes 21 arranged along the column direction, which is beneficial for accurately aligning a column or a row of three-terminal capacitors 1 on the slurry board 2 with the strip end paste 311, thereby improving the sealing effect of the slurry on the three-terminal capacitor 1.

[0035] Specifically, in this embodiment, the spacing between two adjacent openings 321 is the distance between the center line of one opening 321 and the center line of the other opening 321, and the spacing between two through holes 21 is the distance between the center line of one through hole 21 and the center line of the other through hole 21, but is not limited thereto.

[0036] Specifically, in the present embodiment, the rectangular through hole 21 on the slurry plate 2 is extended in the horizontal direction, and the end slurry is scraped in the vertical direction on the slurry platform 31 by a slurry scraper 32, so that the formed strip end slurry 311 extends in the column direction, and the spacing between adjacent strip end slurries 311 is the same as the spacing between two adjacent columns of three-terminal capacitors arranged in the row direction, but not limited to this. In some embodiments, the rectangular through hole 21 on the slurry plate 2 can also be extended in the vertical direction, and the end slurry is scraped in the horizontal direction on the slurry platform 31 by a slurry scraper 32, so that the formed strip end slurry 311 extends in the row direction, and the spacing between adjacent strip end slurries 311 is the same as the spacing between two adjacent rows of three-terminal capacitors arranged in the column direction.

[0037] See also Figures 1 to 4 The surface 11 of the three-terminal capacitor 1 on which the electrode 12 is provided is the first surface and the second surface opposite to each other, and the depth of the through hole 21 is less than the distance between the first surface and the second surface so that one of the first surface and the second surface of the three-terminal capacitor 1 extends out of the through hole 21, which is conducive to accurately applying the terminal paste to the surface 11 of the three-terminal capacitor 1 on which the electrode 12 is provided and preventing the dipping plate 2 from being stained with the terminal paste.

[0038] Specifically, in this embodiment, the first surface and the second surface are perpendicular to the end surface provided with the through electrode 121 , and the first surface and the second surface opposite to each other are provided with the grounding electrode 122 , respectively, but the present invention is not limited thereto.

[0039] See also Figures 1 to 4 The three-terminal capacitor sealing device also includes an introduction plate (not shown), and the introduction plate is provided with a penetrating introduction hole corresponding to the through hole 21. The size of the introduction hole is larger than the size of the through hole 21, which is conducive to the three-terminal capacitor 1 smoothly entering the through hole 21 through the introduction hole, thereby improving the introduction efficiency of the three-terminal capacitor 1.

[0040] Specifically, in the present embodiment, the introduction holes are rectangular and arranged in an array on the introduction plate. The positions of the introduction holes on the introduction plate correspond to the positions of the through holes 21 on the slurry board 2, so that when the introduction plate and the slurry board 2 are stacked, the through holes 21 are completely connected with the introduction holes. After the fixing member 4 is fixed to any surface of the slurry board 2, the introduction plate is stacked on the other surface of the slurry board 2, so that the three-terminal capacitor 1 can be introduced into the through hole 21 by using the introduction hole slightly larger than the through hole 21.

[0041] See also Figures 1 to 4The three-terminal capacitor sealing device also includes a leveling mechanism (not shown), the leveling mechanism includes a leveling platform and a leveling drive device, the fixing member 4 is a tape, the leveling platform is used to place the slurry board 2 with the tape attached, and the leveling drive device is used to level the three-terminal capacitor 1 on the slurry board 2 so that it is close to the tape, so that the height of the three-terminal capacitor 1 on the slurry board 2 is consistent, and the consistency of the growth amount of the slurry when the three-terminal capacitor 1 is dipped is better.

[0042] Specifically, in this embodiment, after the slurry board 2 with the three-terminal capacitor 1 is moved to the leveling platform, the leveling drive device is controlled to press on the upper end of the three-terminal capacitor 1 to level the three-terminal capacitor 1, so that the three-terminal capacitor 1 on the slurry board 2 is tightly attached to the tape.

[0043] Specifically, in this embodiment, the fixing member 4 is a tape. Before the three-terminal capacitor 1 is introduced into the slurry board 2, the tape is first pasted on one side of the slurry board 2, and then the three-terminal capacitor 1 is introduced into the through hole 21 through the other side of the slurry board 2, so that the three-terminal capacitor 1 in the through hole 21 can be fixed by the tape, but it is not limited to this. For example, in some embodiments, the fixing member 4 can be a magnetic member to fix the three-terminal capacitor 1 by magnetic adsorption.

[0044] See also Figures 1 to 4 The dipping mechanism 3 also includes a dipping drive device (not shown), which is detachably mounted with a dipping plate 2. The dipping drive device is used to drive the dipping plate 2 to approach the dipping platform 31 so that the surface 11 of the three-terminal capacitor 1 provided with the electrode 12 contacts the strip end paste 311. The arrangement of the above-mentioned dipping drive device is beneficial to improving the alignment accuracy of the three-terminal capacitor 1 and the strip end paste 311 along the column direction on the dipping plate 2, thereby improving the sealing effect of the surface 11 of the three-terminal capacitor 1 provided with the electrode 12.

[0045] Specifically, in this embodiment, after the three-terminal capacitor 1 is introduced into the dipping plate 2, the dipping plate 2 is flipped 180 degrees so that the dipping plate 2 corresponds to the side of the dipping platform 31 provided with the strip end paste 311, and the flipped dipping plate 2 is fixed on the dipping driving device so that the dipping plate 2 is driven by the dipping driving device to move closer to the dipping platform 31.

[0046] Specifically, in this embodiment, the slurry dipping platform 31 is a silver plate, and a surface of the slurry dipping platform 31 provided with the end slurry is sprayed with a hydrophobic coating to prevent the end slurry from flowing easily.

[0047] See also Figures 1 to 4The three-terminal capacitor sealing device also includes a drying device (not shown) and a vacuum device (not shown). After the slurry plate 2 is placed in the drying device, the air in the drying device needs to be extracted by the vacuum device, and then the three-terminal capacitor 1 with the terminal slurry on the surface 11 is heated and dried by the drying device, which is beneficial to prevent holes from appearing at the slurry and affecting the sealing effect of the three-terminal capacitor 1.

[0048] See also Figures 1 to 5 The present invention also discloses a method for sealing a three-terminal capacitor 1 using the above three-terminal capacitor sealing device, the method comprising:

[0049] Step 101, fix the fixing member 4 on any surface of the slurry-sucking board 2;

[0050] It is understandable that in step 101 , the adhesive tape is attached to any surface of the slurry board 2 , but the present invention is not limited thereto.

[0051] Step 102, introducing the three-terminal capacitor 1 into the through hole 21 on the slurry board 2, so that the fixing member 4 fixes one side of the three-terminal capacitor 1, and the surface of the other side of the three-terminal capacitor 1 provided with the electrode 12 is exposed outward;

[0052] It can be understood that in step 102, the three-terminal capacitor 1 is introduced into the through hole 21 on the slurry board 2 by using a guide plate, so as to improve the efficiency of introducing the three-terminal capacitor 1, and after step 102, it also includes step 1021, placing the slurry board 2 on a leveling platform, and controlling the leveling drive device to level the three-terminal capacitor 1 so that the three-terminal capacitor 1 is close to the tape.

[0053] Step 103, using the scraper 32 to shape the end pulp on the pulp dipping platform 31 into a strip-shaped end pulp 311;

[0054] It can be understood that in step 102, the end pulp is scraped vertically on the pulp dipping platform 31 by the pulp scraper 32 to form a strip-shaped end pulp 311 extending vertically, but the present invention is not limited thereto.

[0055] Step 104, moving the dipping plate 2 close to the dipping platform 31, so that the surface 11 of the three-terminal capacitor 1 accommodated in the through hole 21 and provided with the electrode 12 is in contact with the strip-shaped terminal paste 311;

[0056] It is understandable that in step 104 , the slurry driving device is used to drive the slurry plate 2 to move closer to the slurry platform 31 , which is beneficial to improving the alignment accuracy between the three-terminal capacitor 1 and the strip-shaped terminal slurry 311 on the slurry plate 2 , but is not limited thereto.

[0057] Step 105, placing the paste-coated plate 2 into a drying device, and heating and drying the three-terminal capacitor 1 with the end paste on the surface 11;

[0058] It is understandable that after the slurry-coated board 2 is placed in the drying device in step 105, the air in the drying device is first evacuated by a vacuum device before the drying operation is performed.

[0059] The present invention aims at a structure in which the surface 11 of the three-terminal capacitor 1 is provided with an electrode 12 , and uses the above-mentioned three-terminal capacitor sealing device to perform a sealing operation on the three-terminal capacitor 1 , which is beneficial to improving the overall sealing efficiency and sealing effect of the three-terminal capacitor 1 .

[0060] See also Figures 1 to 5 , further, after step 105, it also includes:

[0061] Step 106, fix another fixing member 4 on the other surface of the slurry board 2, remove the previous fixing member 4 to expose another surface 11 of the three-terminal capacitor 1 provided with the electrode 12, and repeat steps 103 to 105.

[0062] It is understandable that after the sealing of the grounding electrode 122 on the first surface of the three-terminal capacitor 1 is completed, it is necessary to change the surface to seal the grounding electrode 122 set on the second surface of the three-terminal capacitor 1. In step 106, the side of the slurry board 2 close to the first surface of the three-terminal capacitor 1 is also pasted with tape, and the tape on the side of the slurry board 2 close to the second surface of the three-terminal capacitor 1 is torn off to expose the second surface of the three-terminal capacitor 1. Then, the three-terminal capacitor 1 is flattened by a flattening mechanism, and then steps 103 to 105 are repeated to perform slurrying and heating and drying operations on the grounding electrode 122 set on the second surface of the three-terminal capacitor 1.

[0063] The above disclosure is only the preferred embodiment of the present invention, which certainly cannot be used to limit the scope of rights of the present invention. Therefore, equivalent changes made according to the scope of the patent application of the present invention are still within the scope covered by the present invention.
