However, the scope of protection of this utility model is not limited to the following specific embodiments.

[0020] It should be noted that when a component is described as being "fixed to, attached to, connected to or connected to" another component, it can be directly fixed to, attached to, connected to or connected to the other component, or it can be indirectly fixed to, attached to, connected to or connected to the other component through other intermediate connectors.

[0021] Unless otherwise defined, all technical terms used herein have the same meaning as commonly understood by those skilled in the art. The technical terms used herein are for the purpose of describing particular embodiments only and are not intended to limit the scope of protection of this invention. Example 1

[0022] like Figure 1 The capacitor core packing insertion mechanism shown includes a fixing ring 1, a limiting component 2, a transmission component 3, and a feeding component 4. The limiting component 2 is disposed on the fixing ring 1, and the transmission component 3 is connected to the feeding component 4. Figure 2 , Figure 3 and Figure 4 As shown, the limiting component 2 includes an arc-shaped limiting member 21, a positioning block 22, and a movable ring 24. The fixed ring 1 has multiple evenly distributed receiving grooves 11, each containing a positioning block 22. Each positioning block 22 is fixedly connected to an arc-shaped limiting member 21, which is located on one side of the inner ring of the fixed ring 1. The centers of each arc-shaped limiting member 21 are at the same point, and the top of the arc-shaped limiting member 21 has a guiding arc surface 211. A positioning pin 23 is fixedly disposed on the positioning block 22. The bottom of the positioning pin 23 is connected to the fixed ring 1, and its upper part is positioned within the positioning limiting groove 241 of the movable ring 24. The transmission component 3 drives the movable ring 24 to rotate on the fixed ring 1. The positioning limiting groove 241 is arc-shaped and forms a certain angle with the arc of the movable ring 24.

[0023] In this embodiment, asFigures 1-4 As shown, when the transmission assembly 3 drives the movable ring 24 to rotate counterclockwise on the fixed ring 1, under the restriction of the positioning limiting groove 241, the positioning pin 23 on the positioning block 22 drives the arc-shaped limiting member 21 to move inward of the fixed ring 1 under the action of the positioning limiting groove 241; the plurality of arc-shaped limiting members 21 enclose a limiting annulus, the diameter of the limiting annulus is slightly smaller than the inner diameter of the shell 8, and the limiting annulus is directly above the open end of the shell 8, at this time, the core package 6 enters the shell 8, and the core package 6 will not contact the open end of the shell 8, thereby avoiding being scratched; at the same time, the top of the arc-shaped limiting member 21 is provided with a guide arc surface 211, so that even if the core package 6 contacts the arc-shaped limiting member 21, the arc-shaped limiting member 21 will not scratch the core package 6. When the transmission assembly 3 drives the movable ring 24 to rotate clockwise on the fixed ring 1, the plurality of arc-shaped limiting members 21 will be directly above the shell 8 and will be opened.

[0024] In the embodiment, as shown in the figure, Figures 1-5 The feeding assembly 4 includes an upper pressing plate 41, a pressing rod 42, a suction cup 43, and a connecting frame 44; the lower part of the connecting frame 44 is provided with a cam or a protrusion 45 in contact with the follow-up bearing 31 of the transmission assembly 3, and the upper part of the connecting frame 44 is fixedly connected to the upper pressing plate 41; the upper end of the pressing rod 42 is connected to the upper pressing plate 41, and the lower end is provided with the suction cup 43; the upper pressing plate 41 or the connecting frame 44 is connected to a power mechanism (not shown in the figure), and the power mechanism drives the upper pressing plate 41 or the connecting frame 44 to move up and down. The pressing rod 42 is designed with vacuum, the top end of the pressing rod 42 is connected to a negative pressure air pipe (not shown in the figure), and the lower end is communicated with the suction cup 43. In the embodiment, the power mechanism can be a pneumatic cylinder or a servo motor

[0025] In the embodiment, the core package 6 connected with the cover plate 7 is transferred to the lower side of the suction cup 43 by a transfer clamp (not shown in the figure), at this time, the suction cup 43 sucks the cover plate 7 through the negative pressure generated by the negative pressure air pipe, and then under the action of the power mechanism, the suction cup 43 carries the core package 6 and the cover plate 7 into the shell 8 through the limiting assembly 2. In the embodiment, the core package 6 is loaded into the shell 8 by the suction cup 43, rather than falling into the shell 8 by its own gravity, which reduces the impact force when the core package 6 enters the shell, thereby protecting the core package 6 and reducing damage.

[0026] In the embodiment, as shown in the figure, Figure 1 The movable ring 24 is provided with a rotation limiting groove 242, and the fixed ring 1 is provided with a rotation limiting pin 12, the bottom of the rotation limiting pin 12 is fixedly arranged on the fixed ring 1, and the upper part is arranged in the rotation limiting groove 242; the rotation limiting groove 242 is arc-shaped, and the center of the arc-shaped circle is the same as the center of the movable ring 24.

[0027] In the embodiment, as shown in the figure, Figures 1-5As shown, the fixed ring 1 is fixedly connected to the base 5; the transmission assembly 3 comprises a follow-up bearing 31, a sliding block 32 and a connecting rod mechanism 33; the follow-up bearing 31 is in contact with the cam or protrusion 45, the follow-up bearing 31 is connected to the sliding block 32 through a support, the sliding block 32 is arranged on the base 5 through a slide rail 34, one end of the connecting rod mechanism 33 is connected to the sliding block 32 through a rotating shaft and the other end is connected to one side of the movable ring 24 through a rotating shaft, and the connecting rod mechanism 33 drives the movable ring 24 to rotate. In this embodiment, in the process of moving downward, the follow-up bearing 31 is driven by the cam or protrusion 45 on the connecting frame 44 to move forward, thereby driving the sliding block 32 to move forward on the slide rail 34, and the connecting rod mechanism 33 on the sliding block 32 pushes the movable ring 24 to rotate counterclockwise. When the feeding assembly 4 is reset under the action of the power mechanism, the connecting rod mechanism 33 on the sliding block 32 pushes the movable ring 24 to rotate clockwise.

[0028] In this embodiment, when the core package 6 enters the shell, the arc-shaped limiting piece 21 of the limiting assembly 2 is folded, so that the core package 6 enters the outer shell 8 along the arc-shaped limiting piece 21, avoiding contact with the open end of the outer shell 8, thereby ensuring that the core package 6 is not scratched by the open end of the outer shell 8.
