[0025] A welding machine is installed between the two disc clamp devices 5, so that welding can be performed directly on the material transmission path. Such a configuration improves the continuity of the production process and reduces the operation steps.
[0026] A magnifying glass detector is installed on one side of the other disc fixture device 5, which provides the ability to perform quality inspection directly after welding. Such an instant inspection mechanism greatly improves the consistency and reliability of production.

[0028] Working principle: CP wire and aluminum wire are fed into the machine through CP wire feeding line 7 and aluminum wire feeding line 8 respectively. The servo belt transmission device 2 is started by the first servo motor 21, which drives the transmission shaft 23, and then is connected to the three second reduction commutators 24 through pulleys and belts, so that the three second reduction commutators 24 operate simultaneously, and the rotation of the second reduction commutator 24 drives the eccentric wheel 31, and the rotation of the eccentric wheel 31 drives the connecting rod 32 and the rocker 33, so that the rocker 33 swings back and forth, and then drives the sliding block 42 to slide back and forth on the linear guide rail 41, and then the intermittent wire pressing device 44 is used to press the wire. The CP wire is intermittently fed to the cutting machine 45. Similarly, the aluminum wire is also intermittently fed to the cutting machine 45. After being cut into the required length by the cutting machine 45, the top plate 53 is driven by the forward and reverse motors. The top plate 53 rotates to control the opening of the clamp 52. When the CP wire or aluminum wire is intermittently fed to the clamp 52, the clamp 52 closes and clamps the cut CP wire or aluminum wire. At the same time, the second reduction commutator 24 drives the top plate 53 to rotate, thereby driving the clamp 52 to rotate. When the cut CP wire and aluminum wire are butt-jointed, the CP wire and the aluminum wire are welded together by a welding machine to form a guide needle. The welding point can be observed through the magnifying glass detector, and then, the clamp 52 holding the CP line is opened, and the clamp 52 holding the aluminum wire is still closed, and then rotated to the third disc clamp device 5 position through the second reduction commutator 24. At this time, the clamp 52 of the third disc clamp device 5 is opened, and the guide pin is clamped and then closed, while the clamp 52 originally holding the guide pin is opened, and then the clamp 52 of the third disc clamp device 5 is rotated to the rivet flattening device 6, and the needle-free detector can be used to detect whether the clamp 52 has a guide pin, and the guide pin is rotated to the top of the aluminum diaphragm 68, and the rivet is driven by the first drive device 63. The needle 64 moves downward to rivet the guide needle and the aluminum diaphragm 68 together, and then the clamp 52 holding the guide needle opens, and the riveted guide needle and the aluminum diaphragm 68 are transferred to the bottom of the pressure block 67 through the guide wheel 69. The second drive device 66 drives the pressure block 67 downward to perform a flattening operation, so that the guide needle and the aluminum diaphragm 68 fit closely to each other, eliminating the burrs generated during riveting. When the first drive device 63 and the second drive device 66 are set to be a certain distance apart, the two can work simultaneously, that is, riveting and flattening operations can also be performed at the same time, thereby reducing the temporary holding time and improving efficiency.
[0029] The implementation of the present invention is not limited to the above-mentioned embodiments. Without departing from the spirit and scope of the present invention, ordinary technicians in this field can make various changes and improvements to the present invention in form and detail, and these are considered to fall within the protection scope of the present invention.
