The first separation mechanism is located between the station track and the feeding track and includes a separation flap, a base, a push rod, a push rod cylinder, an ejection rod, and an ejection cylinder. The two end faces of the separation flap are adjacent to the station track and the feeding track. The separation flap is provided with a separation groove adapted to the contour of a single shell, an inlet extending to the feeding track, an outlet extending to the station track, and a hinge seat. The separation flap is rotatably engaged with the base, and the hinge seat of the separation flap is hinged to the push rod. The push rod cylinder drives the separation flap to rotate around the base until the inlet connects with the feeding track or the outlet connects with the station track. The push rod is parallel and aligned with the station track. The push cylinder drives the push rod to push the housing into the station track from the inlet.

3. The automatic assembly and riveting equipment for AC contactor arc extinguishing components according to claim 2, characterized in that: The vertically lower part of the workstation track is provided with a transport channel. The housing transport device includes a transport fork and a fork drive mechanism. The transport fork is provided with fork slots that are adapted to the housing contour at each workstation spacing. The fork drive mechanism drives the transport fork to perform reciprocating motion of lifting and translating within the transport channel.

4. The automatic assembly and riveting equipment for arc-extinguishing components of AC contactors according to claim 1, characterized in that: The arc-extinguishing component conveying device includes a vibratory plate and several straight vibratory tracks arranged side by side with corresponding insertion slots. The straight vibratory tracks are provided with sliding grooves that are adapted to the contour of the arc-extinguishing component. The arc-extinguishing component assembly device includes a second separation mechanism and an inlet mechanism. The second separation mechanism includes a separation platform and a lifting cylinder. The separation platform is located between the linear vibration track and the assembly end face of the housing. Several lifting slots are arranged side by side corresponding to the number of insertion slots. The outline of the lifting slot is adapted to the outline of the arc-extinguishing component. It has an inlet facing the linear vibration track and an outlet facing the assembly end face. The lifting cylinder drives the inlet of the separation platform to connect with the linear vibration track or the outlet to connect with the insertion slot. The guiding mechanism includes a number of guiding rods corresponding to the number of insertion slots, a guiding seat, and a guiding cylinder. The guiding rods are respectively aligned with the insertion slots and fixed on the guiding seat. The guiding cylinder drives the guiding rods to push the arc-extinguishing component into the insertion slot through the inlet of the separation table.

5. The automatic assembly and riveting equipment for arc-extinguishing components of AC contactors according to claim 4, characterized in that: A detection mechanism is provided at the lifting groove to detect whether there is an arc-extinguishing component inside the lifting groove.

6. The automatic assembly and riveting equipment for AC contactor arc extinguishing components according to any one of claims 1-5, characterized in that: The equipment also includes a discharge track, a fork drive mechanism, a defective product track, and an ejection mechanism at the workstation after the riveting device is installed.
