[0017] The pin limit assembly includes a limit slider 16 and a tension spring 17, wherein a slider groove is provided at the lower part of the cross arm of the transfer seat 14, and a limit groove connected to the slider groove is provided at the lower part of the pin guide tube 15.

A presser foot cylinder 23 is vertically installed on the presser foot support rod 21, and the piston rod of the presser foot cylinder 23 is downwardly connected to the stitch pressing plate 24.

[0018] After adopting the above scheme, the whole system is controlled by an external control electric, the capacitor pins are arranged and transported to the pin transport plate through the external pin arrangement plate, the capacitor rubber plug is sent to the insertion slot of the station disk by the external plug placing system, and the rotating cylinder rotates under the drive of the external motor (a driven gear ring is installed at the lower part of the rotating cylinder, the external motor drives the active gear ring, and the active gear ring drives the driven gear ring to rotate), when the insertion slot with the rubber plug is moved to the bottom of the pin transfer unit; The piston rod of the power cylinder extends out, driving the power connecting rod to move, and the power connecting rod synchronously pushes the hinge of the first connecting rod and the second connecting rod obliquely to move. Under the limiting action of the third connecting rod, the transfer seat and the components on the transfer seat move upward with the hinge point of the third connecting rod and the transfer frame as the center, so that the pin guide cylinder is tilted and docked with the pin conveying plate. During the movement of the transfer seat, under the tension of the tension spring, the pin groove of the limit slider is located in the pin guide cylinder, the needle push rod is located outside the pin guide cylinder, the external control system controls the needle release, and the capacitor pin slides from the pin conveying plate to the pin guide cylinder; After the capacitor pin enters the pin guide, its lower part passes through the pin slot downward. Since the top of the capacitor pin is larger, it will not pass through the pin slot, thereby realizing the positioning of the capacitor pin in the pin guide. The piston rod of the power cylinder contracts, driving the power connecting rod to move. The power connecting rod synchronously pushes the hinge of the first connecting rod and the second connecting rod obliquely to move. Under the limiting action of the third connecting rod, the transfer seat and the components on the transfer seat move downward with the hinge point of the third connecting rod and the transfer frame as the center, so that the pin guide tube moves downward to the top of the plug insertion slot; When the transfer seat is moving, the guide slope of the limit push plate starts to contact with the push plate groove, and gradually pushes the limit slider backward (the tension spring is compressed), and the limit slider gradually withdraws from the pin guide cylinder. At this time, the lower part of the pin contacts with the pin hole on the rubber plug; The piston rod of the push-needle cylinder extends, driving the push-needle rod into the pin guide tube (the push-needle plate completely enters the pin guide tube), and the piston rod of the press-needle cylinder contracts, driving the push-needle cylinder, the push-needle rod and other components downward, and the push-needle plate begins to contact the top of the pin and gradually presses the pin down to insert the pin into the rubber plug. After the pressing is completed, the press-needle cylinder and the push-needle cylinder are reset to the initial state in turn; The rotating cylinder drives the work station disk to rotate one work station to the bottom of the pin presser plate, and the piston rod of the pin presser cylinder extends to drive the pin presser plate downward, pressing the top of the pin into the rubber plug, thereby completing the pin insertion. The structure after adopting this solution is reasonable, the use effect is good, and the operation stability is strong.

[0019] The embodiments described above are only preferred embodiments of the present invention and are not intended to limit the scope of implementation of the present invention.
