Description

Technical Field

[0001] This utility model belongs to the field of capacitor manufacturing technology, and in particular relates to a sealing device for a chip multilayer ceramic capacitor. Background Technology

[0002] Multilayer ceramic chip capacitors, also known as chip capacitors, are made by stacking ceramic dielectric films with printed electrodes in a staggered manner, sintering them at high temperature in one go to form a ceramic chip, and then sealing the two ends of the chip with metal layers to form a monolithic structure, hence the name monolith capacitor.

[0003] In the production of chip capacitors, the exposed ends need to be sealed. Generally, the two ends of the capacitor are coated with end paste. CN220085853U, a sealing device for a multilayer ceramic chip capacitor, proposes to fix the capacitor by installing it through an elastic hole. The elastic plate deforms under force and makes an interference fit with the capacitor. After installation, the elastic plate is mounted on a carrier plate, which slides towards the slurry tank, thereby impregnating the capacitor. Compared to existing sealing devices that use adhesive tape to fix the capacitor, this application uses an interference fit between the elastic plate and the capacitor to prevent the capacitor from falling out of the elastic hole. The capacitor installation operation is simpler, and the overall processing efficiency of the capacitor is improved.

[0004] In the above device, the elastic plate is moved into the slurry tank by the driving component to achieve coating of the capacitor end face. Since the elastic plate is fixed on the carrier plate, the position of the capacitor is fixed. After coating one end of the capacitor, coating the other end is inconvenient. Utility Model Content

[0005] To achieve the above objectives, this utility model proposes a sealing device for a multilayer ceramic chip capacitor, including a housing and a sliding plate that moves up and down above the housing. There are two sliding plates, and connecting strips are detachably installed on the opposite surfaces of the two sliding plates. A fixing plate for fixing the capacitor is rotatably installed on the opposite surfaces of the two connecting strips. A connecting groove is provided on the side of the connecting strip near the fixing plate, and a T-shaped rod that is inserted into the connecting groove is movably provided on the side of the fixing plate near the connecting strip.

[0006] In one example, two support seats are fixed to the upper surface of the container, and a sliding groove is provided on the side of the support seat. The surface of the sliding plate overlaps with the inner wall of the sliding groove. An electric push rod is fixed to the side of the container, and the telescopic end of the electric push rod is fixedly connected to the lower surface of the sliding plate.

[0007] In one example, the sliding plate is L-shaped.

[0008] In one example, slots are provided on the opposite sides of the two sliding plates, an insert that overlaps with the inside of the slot is fixed to the surface of the connecting strip, and a fixing bolt for fixing the position of the insert is threaded to the side of the sliding plate.

[0009] In one example, the upper surface of the fixing plate has an installation opening, the inner wall of the installation opening has an L-shaped groove, an L-shaped operating block is slidably installed inside the L-shaped groove, a spring is fixedly connected to the opposite side of the L-shaped operating block and the L-shaped groove, and a clamp with a rubber pad is installed on the end face of the L-shaped operating block.

[0010] In one example, the opposite faces of the left and right connecting strips are rotatably connected to a connecting shaft via bearings, and the end face of the connecting shaft is fixedly connected to the side of the fixing plate.

[0011] In one example, positioning grooves are provided at both ends of the side of the fixing plate, a T-shaped rod is slidably installed inside the positioning groove, and a spring is installed on the opposite side of the T-shaped rod and the positioning groove.

[0012] In one example, the end face of the T-shaped rod is arc-shaped, and the T-shaped rod is located at the edge of the side of the fixing plate.

[0013] In one example, the upper surface of the container has a placement groove, and a container cover is placed inside the placement groove.

[0014] The sealing device for a multilayer ceramic chip capacitor proposed in this utility model can bring the following beneficial effects:

[0015] 1. By setting a rotatable fixing plate, the capacitor on the fixing plate can be rotated to adjust its orientation. The T-shaped rod and spring can fix the fixing plate after rotation, realizing the interchange of the two ends of the capacitor on the fixing plate, which facilitates the coating of end paste on the two ends of the capacitor.

[0016] 2. An L-shaped operating block, a spring, and a clamp are installed on the fixed plate to fix the capacitor on the fixed plate. The rubber pad on the clamp increases friction and protects the capacitor.

[0017] 3. By setting a cover, the cover can block the end paste inside the container, preventing impurities from entering the end paste. In addition, the cover can provide a flat reference surface, allowing the bottom of the capacitor to overlap with the upper surface of the cover. This can make the bottoms of multiple capacitors flush, ensuring that the downward movement distance of multiple capacitors is the same, and facilitating the simultaneous coating of multiple capacitors.

[0026] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature.

Furthermore, the specific features, structures, materials, or characteristics described may be combined in any suitable manner in one or more solutions or examples.

[0029] like Figures 1-4 As shown, an embodiment of this utility model proposes a sealing device for a multilayer ceramic chip capacitor, which includes a housing 1 for receiving the end paste. A support base 2 is fixedly connected to the upper surface of the housing 1. A sliding plate 3 is slidably installed on the opposite surfaces of the two support bases 2. A sliding groove is opened on the side of the support base 2. The sliding plate 3 slides inside the sliding groove. In order to facilitate the control of the up and down movement of the sliding plate 3, an electric push rod 4 is fixedly connected to both sides of the housing 1. The telescopic end of the electric push rod 4 is fixedly installed on the lower surface of the sliding plate 3.

[0030] A connecting strip 5 is detachably installed between the two sliding plates 3. An insert 7 is installed on the side of the connecting strip 5 facing the sliding plate 3. A slot is opened on the side of the sliding plate 3, and the insert 7 is located inside the slot. A fixing bolt 8 is threadedly connected to the side of the sliding plate 3. The fixing bolt 8 is screwed into the groove opened on the side of the insert 7. A fixing plate 9 is rotatably installed on the opposite side of the left and right connecting strips 5. The fixing plate 9 is located directly above the housing 1. Multiple capacitors are fixed by the fixing plate 9, and the fixing plate 9 drives the capacitors to move into the housing 1 to complete the coating of the capacitor end face. The sliding plate 3 is L-shaped to ensure that the fixing plate 9 can be inserted into the housing 1 when the sliding plate 3 drives the fixing plate 9 to move down.

[0031] To ensure the capacitor is fixed on the mounting plate 9, an installation opening is provided on the upper surface of the mounting plate 9. An L-shaped groove is provided on the inner wall of the installation opening. An L-shaped operating block 10 is slidably installed inside the L-shaped groove. A spring 11 is installed on the opposite side of the L-shaped operating block 10 and the L-shaped groove. Under the elastic force of the spring 11, the L-shaped operating block 10 will move towards the capacitor placed in the installation opening. A clamping plate 12 with a rubber pad is installed on the end face of the L-shaped operating block 10. The clamping plate 12 moves towards the capacitor. The elastic force of the spring 11 causes the clamping plate 12 to clamp the capacitor. At the same time, the rubber pad increases friction to ensure the capacitor is clamped stably.

[0032] The opposite faces of the left and right connecting strips 5 are rotatably connected to the connecting shafts 13 via bearings. The end face of the connecting shafts 13 is fixed to the side of the fixing plate 9. Positioning grooves are provided at both ends of the side of the fixing plate 9. T-shaped rods 14 are slidably installed inside the positioning grooves. The end face of the T-shaped rods 14 is arc-shaped. Springs 15 are installed on the opposite face of the T-shaped rods 14 and the positioning grooves. A connecting groove is provided on the side of the connecting strip 5 facing the fixing plate 9. The T-shaped rods 14 are inserted into the connecting grooves. The elastic force of the springs 15 allows the T-shaped rods 14 to be inserted into the connecting grooves, thus fixing the connecting strips 5 and the fixing plate 9. At the same time, when one side of the fixing plate 9 is pressed down, the arc surface of the T-shaped rods 14 will be actively retracted into the positioning grooves, realizing the rotation of the fixing plate 9. This rotates the other end of the capacitor on the fixing plate 9 to the top of the housing 1, facilitating the coating of the other end of the capacitor.

[0033] The T-shaped rod 14 mentioned above is located at the edge of the side of the fixing plate 9. In actual operation, the edge of the fixing plate 9 is pressed. At this time, the distance between the T-shaped rod 14 and the point of force application can be closer, which can ensure that the T-shaped rod 14 can be actively retracted.

[0034] A cover 6 is installed on top of the container 1. A placement groove is opened on the upper surface of the container 1. The surface of the cover 6 overlaps with the inner wall of the placement groove. The cover 6 can block the end paste in the container 1 to prevent impurities from entering the container 1. The cover 6 is located below the fixing plate 9. When the capacitor is placed, the bottom of the capacitor overlaps with the upper surface of the cover 6, which can ensure that the bottom of each capacitor is on the same plane and that each capacitor is inserted into the end paste to the same depth, which facilitates the coating of multiple capacitors.

[0035] Working principle: Insert the insert 7 into the slot and fix it to the sliding plate 3 with the fixing bolt 8. Start the electric push rod 4 to move the sliding plate 3, so that the fixing plate 9 is close to the cover 6. Push the L-shaped operating block 10 to squeeze the spring 11 and place the capacitor in the mounting hole, so that the capacitor is between the two clamping plates 12. Press down the capacitor so that its bottom overlaps with the upper surface of the cover 6. Release the L-shaped operating block 10. Under the elastic force of the spring 11, the L-shaped operating block 10 drives the clamping plate 12 to clamp and fix the capacitor. Pull out the cover 6. Continue to move the sliding plate 3 down by the electric push rod 4, and the fixing plate 9 moves... The capacitor is inserted into the end of the container 1 for coating. After coating is completed, the fixing plate 9 is lifted to a high position by the electric push rod 4 and one side of the fixing plate 9 is pressed. At this time, the arc surface of the T-shaped rod 14 on the fixing plate 9 is forcefully stored in the positioning groove. The T-shaped rod 14 is disengaged from the connecting groove, and the fixing plate 9 can be rotated 180° to complete the flipping. At this time, the T-shaped rod 14 is rotated to the other side, and the T-shaped rod 14 will be forcefully stored. When it moves to the connecting groove, the spring 15 will push the T-shaped insert into the connecting groove to fix the rotated fixing plate 9. The capacitor on the fixing plate 9 is flipped over, and the other end can be coated.
