[0002] With the continuous progress of society, capacitors have been widely used in all walks of life. There are many types of capacitors popular on the market, but most of them are completed by closing the shell after the capacitor core is built into the shell; this can effectively seal and fix, making it convenient for people to use. However, during the closing process, the sealing plug often shifts. Although it is not possible to observe from the outside whether the sealing plug is sealed and fixed, its internal position has shifted, so that in the later use process, electrolyte leakage will occur; causing the capacitor to short-circuit and be damaged, which not only reduces its overall service life, but also wastes raw materials.

DETAILED DESCRIPTION

[0018] In order to make the technical problems, technical solutions and beneficial effects solved by the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0019] In the present application, the pressing cylinder 2, the first pressing cylinder 5 and the second pressing cylinder 8 are purchased directly from the market according to specific models and then matched and installed, and the operation is controlled by an external controller.

[0020] See Figure 1 and Figure 2 What is shown is a capacitor casing closing device, which has symmetrically arranged columns 1, and tightening cylinders 2 are vertically arranged between the columns 1. The output end of the tightening cylinder 2 is fixed to a top seat 3; a casing fixing column 4 is fixedly arranged on the upper part of the top seat 3; a closing component is fixedly arranged at the upper end of the column 1 between the casing fixing column 4 and the top seat 3, which is used for closing the upper part of the capacitor casing.

[0021] The closing assembly includes a first clamping cylinder 5, a first clamping frame 6, a first arc clamping ring 7, a second clamping cylinder 8, a second clamping frame 9 and a second arc clamping ring 10; the first clamping cylinder 5 and the second clamping cylinder 8 are respectively arranged horizontally opposite to each other, and the output end of the first clamping cylinder 5 is connected to the first arc clamping ring 7 through the first clamping frame 6; the output end of the second clamping cylinder 8 is connected to the second arc clamping ring 10 through the second clamping frame 9, and the first arc clamping ring 7 and the second arc clamping ring 10 are closed to form a circular ring clamping area 11. The first clamping frame 6 is fixed with a plurality of first connecting rods 12 arranged in parallel. The second clamping frame 9 is fixed with a plurality of second connecting rods 13 arranged in parallel. The cross section of the top seat 3 is a stepped structure, and the upper end of the top seat 3 is an open shell structure. The outer shell fixing column 4 includes a fixing column 14, and a cavity 15 is provided in the fixing column 14, and the cavity 15 is filled with foam 16. The length of the cavity 15 in the fixing column 14 is longer than the length of the capacitor pin exposed outside the shell. The lower part of the first pressing cylinder 5 and the lower part of the second pressing cylinder 8 are fixed on the column 1 through a cushion block 17. A plurality of reinforcing rods 18 are arranged parallel to the lower end of the pressing cylinder 2 between the columns 1.

[0022] The operating principle of the capacitor shell closing device is as follows:

[0023] First, the operator inserts the sealing plug into the upper end of the shell, exposing the pins, and directly inserts the exposed pins into the fixing column 4 of the shell, and fixes them by inserting the pins into the foam 16. Then, the external controller controls the tightening cylinder 2 to extend, and the tightening cylinder 2 will push the top seat 3 upward until the bottom of the capacitor contacts the bottom of the top seat 3 and then stops running; in this way, the sealing plug can be effectively positioned; and then the external controller simultaneously controls the first clamping cylinder 5 and the second clamping cylinder 8; so that the first arc-shaped clamping ring 7 and the second arc-shaped clamping ring 10 are closed, and the shell will be compressed and closed during the closing process, so that the sealing plug will also be pressed into the shell for effective sealing and fixing.
