The outside is usually covered with insulating packaging materials to protect the capacitor.

[0003] The pressing equipment for plastic-encapsulated multilayer ceramic capacitors is one of the indispensable key equipment in the production process of plastic-encapsulated multilayer ceramic capacitors. These equipment are mainly used to press ceramic powder into the required shape and size to form the ceramic embryo of plastic-encapsulated multilayer ceramic capacitors.

[0004] The Chinese patent application number 202222594679.4 discloses a well-sealed miniaturized ceramic capacitor, which is designed to solve the problem in the prior art that the current miniaturized ceramic capacitor directly connects the contact electrode to the internal structure, and the sealing effect is not ideal.

[0031] The method for using the plastic package multilayer ceramic capacitor pressing equipment comprises the following steps: S1. First, the mixed, ground and dried ceramic powder is placed in the receiving mold 11. The ceramic powder can be temporarily stored by the receiving mold 11 and the temporary support 39. Then, the hydraulic device 4 can be started to drive the pressing plate 3 into the receiving mold 11, so that the ceramic powder can be squeezed into an embryo. S2, then, the hydraulic device 4 is started again to drive the pressing plate 3 to move upward to the limit position. At the same time, the driving motor 9 is started to drive the second gear 8, the first gear 7 and the winding wheel 6 to rotate simultaneously, so that the connecting rope 5 can pull the receiving mold 11 to move downward, so that the formed embryo can be retained on the top of the temporary bracket 39. Subsequently, when the receiving mold 11 continues to move downward, it can drive the alignment rod 10 to contact the alignment horizontal plate 33, so that the first rack 24 can pass through the third gear 26, driving the second rack 25 to move toward the inside of the placement tube 22, so that the L-shaped push plate 23 can push the envelope 34 out of the inside of the placement tube 22; S3. Finally, when the envelope 34 is completely removed from the inside of the placement tube 22, it can be slid onto the two ends of the molded embryo on the temporary bracket 39 to complete the work of quickly aligning the molded embryo with the envelope 34. Multilayer chip ceramic capacitors, also known as patch capacitors and chip capacitors, are a type of capacitor composed of multiple ceramic layers stacked together with metal electrodes sandwiched between the layers and conductor leads connected at both ends. The outside is usually covered with insulating packaging materials to protect the capacitor. Multilayer chip ceramic capacitors are composed of multiple ceramic layers with metal electrodes sandwiched between each layer, and these layers are stacked together to form an integral structure. High capacitance and compact volume can be achieved by alternating the stacking of ceramic layers and metal electrodes.

[0032] The working principle of Example 1 is as follows: when in use, the elasticity of the second spring 37 drives the storage mold 11 to fit with the temporary bracket 39, so that when the storage mold 11 and the temporary bracket 39 are butt-fitted together, the ceramic powder that has been mixed, ground and dried from the outside can be put into the storage mold 11, and then the hydraulic equipment 4 is started to drive the pressing plate 3 to move downward. In the process of the pressing plate 3 moving downward, the special-shaped extension plate 17 can be released, so that the special-shaped extension plate 17 can drive the first piston rod 18 to move toward the inside of the L-shaped air cylinder 19 under the action of gravity, so that the second piston rod 20 can drive the second alignment key 21 to move toward the end away from the L-shaped air cylinder 19, so that the second alignment key 21 can move to the first alignment key 13. The bottom end of the receiving mold 11 can be prevented from falling down when the pressing plate 3 squeezes the powder inside the receiving mold 11. Subsequently, when the powder inside the receiving mold 11 is squeezed into an embryo, the hydraulic device 4 can be started again to drive the pressing plate 3 to move upward, so that the pressing plate 3 can be moved out from the inside of the receiving mold 11, and when the pressing plate 3 moves upward to the limit position, the special-shaped extension plate 17 can be driven to move upward to the limit position at the same time, so that the first piston rod 18 can be displaced upward from the inside of the L-shaped air cylinder 19, causing the second alignment key 21 to move toward one end close to the L-shaped air cylinder 19, and the second alignment key 21 can be moved out from the bottom end of the first alignment key 13, preventing the first alignment key 13 and the second alignment key 21 from being in contact with each other when the receiving mold 11 moves downward subsequently. The positioning key 21 interferes, and then the driving motor 9 can be started to drive the second gear 8 and the first gear 7 to rotate simultaneously. When the first gear 7 rotates, it can drive the winding wheel 6 to rotate, so that the winding wheel 6 can pull the connecting rope 5 to drive the storage mold 11 to move downward, and the card key at the opposite end of the movable sleeve 12 moves in the card slot in the outer center of the vertical frame 35, so that the storage mold 11 can be ensured to move in a straight line. At the same time, when the storage mold 11 moves downward, the formed embryo can be left on the top of the temporary bracket 39, and when the top of the storage mold 11 moves downward to be flush with the bottom end of the placement tube 22, it can drive the alignment rod 10 to contact the alignment horizontal plate 33. When the storage mold 11 continues to move downward, the alignment rod 10 can squeeze The alignment horizontal plate 33 moves downward, so that the alignment horizontal plate 33 can drive the extended base frame 30, the vertical bracket 28 and the first rack 24 to move downward at the same time, and the vertical bracket 28 is slidably inserted in the interior of the limiting horizontal plate 31, so that the first rack 24 can be guaranteed to move downward in a straight line. When the first rack 24 moves downward, it can drive the third gear 26 to rotate, and the third gear 26 can drive the second rack 25 to move toward one end close to the placement tube 22. The second rack 25 is connected to the L-shaped push plate 23, so that when the second rack 25 is displaced, it can drive the L-shaped push plate 23 to enter the interior of the placement tube 22, so that the L-shaped push plate 23 can push the envelope 34 at the bottom layer inside the placement tube 22. When the first rack 24 moves downward to the limit position,The second rack 25 and the L-shaped push plate 23 can be driven to completely push the envelope 34 out of the interior of the placement tube 22, and the envelope 34 is horizontally aligned with the embryo on the temporary bracket 39, so that when the envelope 34 moves to the extreme position, it can be slidably sleeved on the outer ring of the embryo, so that the envelope 34 can be installed on the embryo, and when the L-shaped push plate 23 enters the interior of the placement tube 22, the top of the L-shaped push plate 23 is flush with the top of the envelope 34, so that the L-shaped push plate 23 can prevent the envelope 34 on the upper layer of the placement tube 22 from falling down in advance. When the envelope 34 and the embryo are assembled, the embryo can be removed from the temporary bracket 39, and then the driving motor 9 is started to drive the second gear 8 to rotate in the opposite direction, so that the connecting rope 5 can be released. At this time, the elasticity of the second spring 37 will drive the storage mold 11 to move upward and reset, and when the storage mold 11 drives the alignment rod 10 and the alignment cross When the plate 33 is completely out of contact, the elasticity of the first spring 32 drives the extension chassis 30 to reset upward, so that the first rack 24 can move upward along the surface of the third gear 26, thereby driving the third gear 26 to rotate in the opposite direction, causing the second rack 25 to drive the L-shaped push plate 23 to move toward the end away from the placement tube 22, until the second rack 25 moves to the original position, and then the end surface of the L-shaped push plate 23 away from the second rack 25 is flush with the end of the placement tube 22 close to the inside of the second rack 25, so that the upper envelope 34 inside the placement tube 22 can fall down to the bottom end of the placement tube 22, completing the filling of the envelope 34, and then, when the storage mold 11 moves upward to reset, it can drive the first alignment key 13 to move to the original position, so that the bottom end of the first alignment key 13 can be just above the second alignment key 21, completing the reset of the storage mold 11.

[0033] Example 2

[0034] On the basis of Example 1, Figure 8 As shown, the support base 36 also includes a hydraulic cylinder 40 and a transverse push plate 41 . The hydraulic cylinder 40 is fixedly mounted on the front end top of the support base 36 , and the transverse push plate 41 is fixedly mounted on the rear end of the hydraulic cylinder 40 .

[0035] When implementing this embodiment, when the sleeve 34 is installed to both ends of the embryo, the hydraulic cylinder 40 can be started, and the bottom end of the lateral push plate 41 can be flush with the top surface of the temporary bracket 39, so that when the lateral push plate 41 moves toward the end close to the storage mold 11, it can push the embryo on the temporary bracket 39, so that the embryo can be removed from the temporary bracket 39, avoiding damage to the embryo when it is manually removed, and completing the work.
