Description

Technical Field

[0001] The utility model relates to a production device of an aluminum electrolytic capacitor, in particular to a core package inserting device for a shell. Background Art

[0002] In the production process of an aluminum electrolytic capacitor, an assembly step is required. When assembling, the core package needs to be placed into the aluminum shell. The existing method is to use a push rod to push the aluminum shell to the aluminum shell position of the guide die. However, since there is rigid contact between the push rod, the aluminum shell and the guide die, there is a certain gap between the open end of the aluminum shell and the positioning step in the guide die. This gap will further increase with the wear of the device. When the core package enters the aluminum shell from the core package position of the guide die, since a certain gap needs to be left for the core package to pass through the core package position, the core package is not completely vertical when entering the aluminum shell. When there is a certain gap between the open end of the aluminum shell and the positioning step in the guide die, the open end of the aluminum shell may scratch the core package, resulting in the scrapping of the core package. Content of the Utility Model

[0003] The technical problem to be solved by the utility model is to overcome the deficiencies of the prior art and provide a core package inserting device for a shell that is not easy to scratch the core package.

[0004] To solve the above technical problem, the technical solution proposed by the utility model is: a core package inserting device for a shell, including a guide die, a push rod, a rotating member and an aluminum shell conveying groove. The push rod is arranged below the end of the aluminum shell conveying groove, and the push rod is hollow and communicated with an air pump. The guide die is arranged above the end of the aluminum shell conveying groove, and the guide die is connected to the rotating member.

[0005] For the above core package inserting device for a shell, preferably, a through hole through which the push rod passes is arranged at the end of the aluminum shell conveying groove.

[0006] For the above core package inserting device for a shell, preferably, the guide die includes a core package position and an aluminum shell position. The aluminum shell position is located below the core package position, and the core package position is in a horn shape. The diameter of the aluminum shell position is larger than the diameter of the end of the core package position, so as to form a positioning step at the joint of the core package position and the aluminum shell position. The width of the positioning step is equal to the thickness of the aluminum shell side wall.

[0007] For the above core package inserting device for a shell, preferably, the guide die includes a left die and a right die which are symmetrically arranged.

The technical terms used herein are only for the purpose of describing specific embodiments and are not intended to limit the protection scope of the present utility model. Embodiment

[0019] As Figure 1A core package into shell device as shown includes a guiding die 1, a ejector rod 2, a rotating part 3 and an aluminum shell conveying trough 4. As Figure 2 shown, the ejector rod 2 is arranged below the end of the aluminum shell conveying trough 4. The ejector rod 2 is hollow and the lower part of the ejector rod 2 is communicated with an air pump through an elbow valve 7. The guiding die 1 is arranged above the end of the aluminum shell conveying trough 4, and the guiding die 1 is connected to the rotating part 3. A through hole through which the ejector rod 2 passes is arranged at the end of the aluminum shell conveying trough 4.

[0020] As Figure 3 and Figure 4 shown, in this embodiment, the guiding die 1 includes a core package position 5 and an aluminum shell position 6. The aluminum shell position 6 is located below the core package position 5, and the core package position 5 is in a horn shape. As Figure 5 shown, the diameter of the aluminum shell position 6 is larger than the diameter of the end of the core package position 5, so as to form a positioning step 15 at the joint of the core package position 5 and the aluminum shell position 6. The width of the positioning step 15 is equal to the thickness of the aluminum shell side wall.

[0021] In this embodiment, when the ejector rod 2 pushes the aluminum shell 8 into the guiding die 1, the ejector rod 2 pushes the aluminum shell 8 to the highest point. At this time, the open end of the aluminum shell 8 has not been pushed against the positioning step 15, that is, there is still a gap between the positioning step 15 and the open end of the aluminum shell. Since the core package is not completely vertical when passing through the core package position 5, if the aluminum shell is put into the shell at this time, the open end of the aluminum shell may scratch the core package. In this embodiment, when the ejector rod 2 pushes the aluminum shell to the highest point, due to the gas passing through the ejector rod 2, under the action of air pressure, the aluminum shell is continuously pushed upward, so that the open end of the aluminum shell is pushed against the positioning step 15. At this time, the guiding die 1 clamps the aluminum shell. Since the width of the positioning step 15 is equal to the thickness of the aluminum shell side wall, the inner wall of the aluminum shell and the inner wall of the aluminum shell position 6 of the guiding die 1 are smooth at this time. Since there is no gap between the open end of the aluminum shell and the positioning step 15, and the inner wall of the aluminum shell and the inner wall of the aluminum shell position 6 of the guiding die 1 are smooth, when the core package enters the aluminum shell, it is not easily scratched by the open end of the aluminum shell.

[0022] In this embodiment, as Figure 3 and Figure 4As shown, the guiding die 1 includes a left die 11 and a right die 12 which are symmetrically arranged. After the left die 11 and the right die 12 are closed, a core package position 5 and an aluminum shell position 6 are formed; a meshing gear member 13 is respectively arranged on the left die 11 and the right die 12; a ejector 14 is arranged on the gear member 13 on the left die 11 or the gear member 13 on the right die 12. In this embodiment, when the aluminum shell enters the guiding die 1, the left die 11 and the right die 12 are open, that is, at this time, the diameter of the aluminum shell position 6 in the guiding die 1 is slightly larger than the diameter of the aluminum shell, so as to ensure that the aluminum shell can smoothly enter the guiding die 1; when the open end of the aluminum shell abuts against the positioning step 15, the left die 11 and the right die 12 are clamped, so that the guiding die 1 clamps the aluminum shell. The core package drops from the horn-shaped core package position 5 and accurately enters the aluminum shell under the restriction of the inner wall at the bottom of the core package position 5; then the rotating member 3 is used to transfer the aluminum shell containing the core package to the next working station.

[0023] In this embodiment, the opening or clamping of the left die 11 and the right die 12 is realized by the gear member 13 and the ejector 14 connected to the left die 11 and the right die 12. When the ejector 14 is under the action of an external force, it drives the gear to rotate, so as to open or clamp between the left die 11 and the right die 12.

[0024] In this embodiment, the ejector rod 2 is provided with a hollow interior and is communicated with an air pump; in this way, when the ejector rod 2 pushes the aluminum shell into the guiding die 1 and air is introduced into the ejector rod 2, the aluminum shell can be further pushed upward, so that the open end of the aluminum shell is pushed against the positioning step 15 by air pressure, so that there is no gap between the positioning step 15 and the open end of the aluminum shell, and the core package sliding into the aluminum shell will not be scratched.
