The limiting blocks 221 are made of stainless steel materials, the surfaces of the radiating fins are not scratched, and matching holes are formed in the limiting arms, so that when the radiating fin glue nails are assembled, the nails jack up upwards from the bottoms of the radiating fin glue nails and are matched with the radiating fin mounting holes.

Furthermore, a chamfer which is upward and inclined towards the outside of the accommodating area is arranged at the upper edge of the side wall of each limiting arm towards the accommodating area, so that the radiating fins can be more smoothly placed into the accommodating area.

In the invention, an inspection station can be arranged between the feeding station and the glue nail mounting station, an inspection device 7 is arranged at the inspection station, and the inspection device 7 is used for detecting whether a cooling fin is arranged at the inspection station. The inspection device 7 comprises an optical fiber sensor 613a, the optical fiber sensor 613a is fixed on the machine base 1 through a support column, and the height of the optical fiber sensor 613a can be adjusted up and down through screws, so that the automatic identification of the cooling fins with different heights can be realized, the judgment on the existence of the cooling fins is realized, and the accuracy of each feeding is ensured.

In the invention, each device can be electrically connected with a controller so as to control the work of the device at each station through the controller, thereby realizing the full-automatic assembly of the radiating fin component and saving the labor. The way in which the controller controls the operation of the devices is known in the art and will not be described in detail here.

The above description is only an alternative embodiment of the present invention, and not intended to limit the scope of the present invention, and all equivalent structures made by using the contents of the specification and the drawings of the present invention, or directly or indirectly applied to other related technical fields, are included in the scope of the present invention.
