[0032] The working process is as follows:

[0033] In the present invention, the motor drives the belt to rotate, and the belt drives the inner large cam and the outer small cam to operate simultaneously. The upper swing rod and the lower swing rod swing up and down, driving the first slider, the second slider, and the third slider to slide up and down. The first slider, the second slider, and the third slider slide up and down, driving the upper clamp and the lower clamp to move up and down to achieve the purpose of loosening and clamping. The push rod moves left and right, driving the sliding table and the slider seat to move left and right;

[0034] When the end of the upper swing rod fixedly connected to the inner large cam swings downward, the end of the upper swing rod fixedly connected to the first slider will pull the first slider upward. At the same time, the second slider fixedly connected to the first slider will also slide upward. At this time, the thumb clamp fixedly connected to the second slider slides upward;

[0035] When the end of the lower swing rod fixedly connected to the outer small cam swings upward, the end of the lower swing rod connected to the third slider will pull the third slider downward. At the same time, the lower clamp fixedly connected to the third slider slides downward. During this period, the push rod remains stationary. At this time, the clamping mechanism is in a loosened state;

[0036] When the end of the upper swing rod fixedly connected to the inner large cam moves downward until the upper swing rod is in a horizontal state, the end of the first slider fixedly connected to the upper swing rod will pull the first slider downward. At the same time, the second slider fixedly connected to the first slider will also slide downward. At this time, the upper clamp fixedly connected to the second slider slides downward;

[0037] When the end of the lower swing rod fixedly connected to the outer small cam moves upward until the lower swing rod is in a horizontal state, the end of the third slider fixedly connected to the lower swing rod will pull the third slider upward. At this time, the lower clamp fixedly connected to the third slider slides upward. At this time, the push rod moves forward to the right, and the sliding table fixedly connected to the push rod, the slider seat fixedly connected to the push rod, and the third slider fixedly connected to the slider seat also move forward to the right. At this time, the clamping mechanism is in a clamping state where the upper clamp and the lower clamp clamp the tantalum capacitor, and positioning is maintained while clamping;

[0038] Meanwhile, the servo motor of the material receiving and welding mechanism drives the push rod seat and the push block, and the push rod seat and the push block will push the steel bar placed on the inclined plate to move. At this time, the welding machine set above the upper clip directly welds the tantalum wire of the tantalum capacitor on the steel bar;

[0039] After the welding action is completed, the steel bar continues to move, and the welding action of the tantalum wire of the next tantalum capacitor is repeated.

[0040] In this embodiment, the first slider, the second slider, and the third slider can also be slid by using a guide rail method, and the motor drive belt drive method of the cam mechanism can be changed to a servo drive or a cylinder drive.
