[0029] The specific embodiments of the present application will be further described in conjunction with the accompanying drawings and examples. The following examples are used to illustrate the present application, but not to limit the scope of the present application.

[0030] The terms "upper", "lower", "front", "back", "left", "right", "top", "bottom", "inner", "outer", "vertical", "horizontal" and the like in the description and claims of the present application indicate the orientations or positional relationships based on the orientations or positional relationships shown in the drawings, and are only used to express the technical solutions clearly and conveniently, and therefore cannot be understood as limitations on the present application.

[0031] Please refer to Figures 1-3 and Figure 11 A capacitor single-beam module vertical pre-sealing mechanism is arranged on a machine table 70, and includes a beam module 20, a rotating assembly 10, a cam driving assembly 60, a thimble assembly 30, a pre-sealing assembly 40 and a beam waist assembly 50.

[0032] The rotating assembly 10 is arranged on the machine table 70, and the rotating assembly 10 includes a rotating seat 11, which is rotationally arranged on the machine table 70; the beam module 20 is arranged on the machine table 70 and is arranged in a spaced manner with the rotating seat 11, and the beam module 20 is used for clamping a capacitor 100 to be pre-sealed and driving the capacitor 100 to rotate; the thimble assembly 30 is located above the beam module 20, and the thimble assembly 30 is used for pushing the capacitor 100 to be pre-sealed on the beam module 20 into position; the pre-sealing assembly 40 is installed on the rotating seat 11, and the pre-sealing assembly 40 includes a pre-sealing wheel 41, which is used for cooperating with the beam module 20 to perform a pre-sealing operation on the capacitor 100; the beam waist assembly 50 is installed on the rotating seat 11, and the beam waist assembly 50 includes a beam waist wheel 51, which is located on one side of the pre-sealing wheel 41 and is used for cooperating with the beam module 20 to perform a beam waist operation on the capacitor 100.

[0033] The axial distance between the pre-sealing wheel 41 and the beam module 20 is less than the axial distance between the beam waist wheel 51 and the beam module 20, so that the pre-sealing wheel 41 and the beam waist wheel 51 can abut against the capacitor 100 in sequence, realizing the pre-sealing operation first and then the beam waist operation.

[0034] The cam driving assembly 60 is connected with the rotating seat 11, and is used to drive the rotating seat 11 to reciprocally rotate on the machine table 70, so as to drive the pre-sealing wheel 41 and the waist binding wheel 51 to reciprocally rotate with the rotating seat 11, thereby realizing that the pre-sealing wheel 41 and the waist binding wheel 51 are automatically away from the capacitor 100 after approaching and abutting against the capacitor 100 on the beam die 20 respectively, and completing the pre-sealing work and the waist binding work of the capacitor 100.

[0035] During work, the ejector pin assembly 30 abuts against the capacitor 100 to be pre-sealed on the beam die 20, so as to push the capacitor 100 into position, the beam die 20 clamps and drives the capacitor 100 to rotate, and the cam driving assembly 60 drives the rotating seat 11 to rotate, so as to drive the pre-sealing wheel 41 and the waist binding wheel 51 to abut against the capacitor 100 respectively.

[0036] In the embodiment, when the pre-sealing wheel 41 and the waist binding wheel 51 abut against the capacitor 100 rotating on the beam die 20 respectively, the pre-sealing wheel 41 and the waist binding wheel 51 rotate with the capacitor 100 respectively. The beam die 20 can drive the capacitor 100 to rotate 2.5-3 times, so that the pre-sealing effect of the capacitor 100 reaches an ideal state, and the capacitor single-beam die group pre-sealing mechanism can pre-seal and bind the waist of 110 capacitors 100 per minute.

[0037] From the above, the capacitor single-beam die group pre-sealing mechanism has a relatively simple structure. Through cooperation of the ejector pin assembly 30 and the beam die 20, the capacitor 100 to be pre-sealed can be accurately placed into position on the beam die 20, so that the capacitor 100 is prevented from being inclined during pre-sealing, thereby affecting the pre-sealing effect. Through cooperation of the cam driving assembly 60, the rotating assembly 10, the beam die 20, the pre-sealing assembly 40 and the waist binding assembly 50, the pre-sealing wheel 41 and the waist binding wheel 51 can abut against the aluminum shell 102 of the capacitor 100 on the beam die 20 respectively, so that the capacitor 100 is pre-sealed first and then bound in the waist. Pre-sealing the capacitor 100 first can effectively prevent the capacitor 100 from being inclined due to extrusion of the waist binding wheel 51 during waist binding, thereby improving the sealing effect of the capacitor 100 and improving the sealing property. The capacitor single-beam die group pre-sealing mechanism not only has a simple structure, but also improves the pre-sealing effect of the capacitor 100 and improves the product yield.

The transmission block 13 is further connected with the cam driving assembly 60. The transmission block 13 cooperates with the cam driving assembly 60 to drive the rotating base 11 to rotate around the main shaft 12, thereby driving the pre-sealing wheel 41 and the waist binding wheel 51 to approach or move away from the binding mold 20.

In operation, after the worker or the mechanical hand places the capacitor 100 to be pre-sealed on the beam die 20, the lifting cylinder 32 drives the needle 31 to move downward so that the needle 31 abuts against the rubber particles 101 of the capacitor 100 on the beam die 20 to push the capacitor 100 to be accurately placed in position, preventing the rubber particles 101 of the capacitor 100 from being skewed due to the inclined placement of the capacitor 100 in the pre-sealing process, thereby affecting the pre-sealing effect. Subsequently, the lifting cylinder 32 drives the needle 31 to return to the initial position, and the capacitor single-beam die group vertical pre-sealing mechanism starts the pre-sealing and waist-beam operation.
