In order to achieve the above purpose, the utility model provides a heat sink pin foot riveting device, including a riveting press machine, a fixture and a jig, the fixture has a working groove for accommodating a row of heat sinks sliding, and the riveting press The machine includes a riveting head that is slidably arranged above the working tank. The riveting head has two pressing parts that protrude downward, and the two pressing parts are respectively connected with the heat dissipation parts in the working tank. The two pins on the sheet are opposite to each other, and the jig is provided with a guide chute for accommodating a row of the radiating fins to slide, and the guide chute is docked with the working groove.

Compared with the prior art, since the heat sink pin foot riveting device of the utility model is equipped with the jig for the riveting press, and the jig is provided with the guide chute, the riveting press A row of cooling fins can be placed in the guide chute before. When performing riveting work, the guide chute is docked with the working groove, and then the riveting press is started to gradually push a row of cooling fins into the working groove, so that the riveting press can continuously Riveting the pins on multiple heat sinks greatly improves work efficiency.

Preferably, a plurality of the guide slides are arranged side by side on the jig. By arranging a plurality of guide chute on the jig, when the cooling fins in one of the guide chute are all pushed into the working groove, the jig can be translated to make the other guide chute The groove is connected to the working groove, so that the riveting work can continue until all the heat sinks on the fixture are used up before the jig needs to be replaced, which reduces the number of times and time-consuming to replace the jig, and further improves work efficiency .

Preferably, a filter is provided on the fixture, and the filter is located between the riveting head and the jig and is closed on the working groove. The function of the filter sheet is to filter out the incorrectly placed heat sinks in the working tank, so as to prevent the misplaced heat sinks from being crushed.

Preferably, the riveting machine is located at one end of the jig, and the heat sink pin foot riveting device further includes a pushing mechanism at the other end of the jig, and the pushing mechanism includes a A push rod that slides in the guide chute and slides along the length direction of the guide chute. The pushing mechanism can automatically complete the work of pushing the cooling fins into the working groove without manual pushing, which improves the automation degree of the device.

detailed description

Preferred embodiments of the present utility model are described below in conjunction with the accompanying drawings of the description.

As shown in FIG. 2 , the utility model provides a heat sink pin foot riveting device for riveting and fixing the pin foot 8 shown in FIG. 1 on the heat sink 9 .

The heat sink pin foot riveting device includes a riveting press 1 , a jig 2 and a jig 3 , and the riveting press 1 and the jig 2 are fixed on a bottom plate 4 . The clamp 2 has a working slot 20 with both ends open, and the width of the working slot 20 can accommodate a row of cooling fins 9 sliding therein. The riveting press 1 includes a riveting head 11 that can slide up and down. The riveting head 11 is located directly above the working groove 20, and the riveting head 11 has two downwardly protruding pressing parts 111. The pressing parts 111 work along the The groove 20 extends along the length direction, and the two pressing parts 111 are respectively opposite to the two pins 8 on the heat sink 9 in the working groove 20 .

The jig 3 has a plate-like structure, and a number of parallel guide chute 31 is arranged side by side on the jig 3. The width of the guide chute 31 is the same as that of the working groove 20, and can also accommodate a row of heat sinks 9 sliding therein. . The jig 3 is independent of the riveting press 1 and the jig 2 , and the jig 3 can be abutted against one end of the jig 2 so that the guide chute 31 is docked with the working groove 20 .

A filter 5 is also provided on the jig 2 , and the filter 5 is located between the riveting head 11 and the jig 3 and is closed on the working groove 20 .

Before starting the riveting work, first fill the cooling fins 9 in several guide chute 31 on the fixture 3, then make one end of one of the guide chute 31 dock with one end of the working groove 20, start the riveting press 1, The cooling fins 9 are continuously pushed into the working groove 20 from the other end of the guide chute 31 by hand. The riveting head 11 of the riveting press 1 keeps moving up and down. When moving down, the two pressing parts 111 of the riveting head 11 are respectively pressed onto the two pins 8 on the heat sink 9 to be fixed on the heat sink. 9. The radiating fin 9 after riveting is deviated from the other end of the working groove 20 . After all the cooling fins 9 in one of the guide chute 31 are riveted, the jig 3 is translated to make the other guide chute 31 connect with the working groove 20 . After all the heat sinks 9 in the jig 3 are riveted, the jig 3 is removed and another jig 3 full of heat sinks 9 is replaced. In the process of pushing the cooling fins 9 into the working groove 20, a very small number of cooling fins 9 may be dislocated and tilted. At this time, the filter sheet 5 can block these dislocated cooling fins 9 to prevent them from moving to the riveting position. Below the indenter 11 and be crushed.

Compared with the prior art, the pin foot riveting device of the heat sink of the utility model can carry out continuous riveting work, and the efficiency is greatly improved.

In order to improve the degree of automation, a push mechanism can also be configured for the heat sink pin foot riveting device. The riveting press 1 is located at one end of the jig 3 , and the push mechanism is located at the other end of the jig 3 . The pushing mechanism includes a push rod extending into the guide chute 31 and sliding along the length direction of the guide chute 31 , the push rod can automatically push the cooling fin 9 from the guide chute 31 into the working groove 20 . In the pushing mechanism, what drives the push rod to move may be devices and components such as cylinders, racks and pinions.
