Description

Technical Field

[0001] The utility model relates to the technical field of capacitor production, in particular to a sealing device for capacitors. Background Technique

[0002] Capacitor production involves multiple process steps and technologies, and strict control and process management are required from raw material preparation to final product assembly and testing. After the assembly of the electrodes and the dielectric, the capacitor usually needs to be encapsulated in a housing to protect the internal structure and provide external lead connections. The encapsulation usually uses a metal housing or a plastic housing, and the housing is sealed by methods such as welding, bonding, or pressing.

[0003] Currently, when the existing sealing device for capacitors presses the housing and the lid, it is usually necessary to first cover the lid on the upper end of the housing, so that the lid will not be displaced during the subsequent sealing with the pressing device. However, such a sealing method has low efficiency, and manually placing the lid is likely to cause the lid to tilt, resulting in ineffective docking of the lid during subsequent pressing. Content of the Utility Model

[0004] The purpose of the utility model is to provide a sealing device for capacitors to solve the problems raised in the above background technique.

[0026] In this embodiment, when it is necessary to seal the capacitor housing and the cover by pressing, the housing is placed in the bottom groove 3 in the middle of the storage table 2, then the cover is placed in the through groove 7 in the middle of the movable plate 6 and is supported by the supporting plate 21, then the first cylinder 9 is started, and the first cylinder 9 clamps and fixes both sides of the bottom end of the housing through the clamping plate 10. After the pressing plate 12 presses down, it drives the movable plate 6 to descend synchronously. At the same time, the four corners of the movable plate 6 will compress the spring 14. After the processing is completed, the pressing plate 12 retracts, and the compressed spring 14 will elastically lift the movable plate 6, so that the cover disengages from the through groove 7. In this way, manual positioning is not required during processing.

[0027] As Figure 4As shown, the movable plate 6 is movably installed between the bottom plate 1 and the top plate 4. A through groove 7 is formed in the middle of the movable plate 6. Clamping mechanisms II are arranged on both sides of the top end of the movable plate 6. The clamping mechanism II includes fixing seats II 15. The fixing seats II 15 are fixedly installed on both sides of the movable plate 6. A cylinder II 16 is arranged on the back of the fixing seat II 15. The output shaft of the cylinder II 16 is fixedly installed with a shaft frame 17. A guide roller 18 is movably installed on the inner side of the front of the shaft frame 17 through a rotating shaft;

[0028] In this embodiment, cylinders II 16 are arranged at the upper ends of both sides of the movable plate 6 of the device. The output shafts of the cylinders II 16 are installed with shaft frames 17. Guide rollers 18 are movably installed on the fronts of the shaft frames 17. After the cylinders II 16 are started, the shaft frames 17 and the guide rollers 18 are controlled to push forward, and the guide rollers 18 are used to clamp the shell cover. When the pressing plate 12 presses down, both sides of the shell cover are movably connected to the guide rollers 18, so it can slide down after being guided by the guide rollers 18. In this way, while clamping, it is also convenient for guiding, so as to achieve the purpose of being convenient for clamping.

[0029] As Figure 4 shown, an opening and closing mechanism is arranged on one side of the bottom end of the movable plate 6. The opening and closing mechanism includes a fixing seat III 19. The fixing seat III 19 is arranged on one side of the bottom end of the movable plate 6. A cylinder III 20 is fixedly installed on the back of the fixing seat III 19. The output shaft of the cylinder III 20 is fixedly installed with a support plate 21. The support plate 21 is movably connected to the outer side of the bottom end of the through groove 7;

[0030] In this embodiment, a cylinder III 20 is arranged below one side of the movable plate 6 of the device. During feeding, the cylinder III 20 controls the support plate 21 to block the lower part of the through groove 7, so that the shell cover can be lifted in the through groove 7. When it is necessary to press and seal, the support plate 21 is retracted from the lower part of the through groove 7 through the cylinder III 20. In this way, the shell cover can be sealed on the upper end of the shell body through the pressing plate 12, so as to achieve the purpose of being convenient for feeding and discharging.

[0031] Working principle: When it is necessary to seal the capacitor shell and the shell cover by pressing, the shell is placed in the bottom groove 3 in the middle of the storage table 2, and then the shell cover is placed in the through groove 7 in the middle of the movable plate 6, and is lifted by the support plate 21, and then the cylinder 1 9 is started, and the cylinder 1 9 clamps the two sides of the bottom end of the shell through the clamping plate 10, and then the cylinder 2 16 is started, and the cylinder 2 16 pushes the shaft frame 17 forward, and clamps the shell cover through the guide roller 18 at the front of the shaft frame 17, and then the hydraulic rod 11 is started, and the hydraulic rod 11 controls the pressing plate 12 to press down, After the pressing plate 12 is pressed down, it drives the movable plate 6 to descend synchronously until the supporting plate 21 is located directly above the shell cover, and then the cylinder three 20 is started. The cylinder three 20 retracts the supporting plate 21 from the bottom end of the through slot 7. At this time, the pressing plate 12 is continuously controlled to be pressed down, so that the pressing plate 12 will press the shell cover in the middle of the through slot 7 onto the upper end of the shell body for sealing. After sealing, the pressing plate 12 is controlled to be lifted and reset. At this time, the spring 14 will control the movable plate 6 to be lifted and reset synchronously, so that the shell cover is separated from the through slot 7. Then, the clamping plate 10 is controlled to be retracted and the sealed capacitor can be removed.
