Moreover, when the rivet is pressed by the pressing part 321, the pressing force applied to the rivet by the pressing part 321 can be in a proper range, the assembly effect of the radiator 600 relative to the main board is good, and the possibility that the radiator 600 is easily separated from the main board in later stage because the radiator 600 is assembled with the main board in a poor state when the pressing force of the radiator 600 is small is reduced.

Referring to fig. 1 and 2, in one embodiment of the present utility model, the number of air pumps 530 is two, and the two air pumps 530 are respectively disposed at two sides of the length direction of the press-fitting device, specifically, the length direction of the press-fitting device is xx' direction in fig. 1 and 2. The first driving assembly 510 and the second driving assembly 520 are adapted to the number of the air pumps 530, so that the driving forces provided by the two air pumps 530 are more balanced and the entire moving process is more stable when the mounting assembly 200 and the press-fitting assembly 300 are close to or far away from the base assembly 100.

Referring to fig. 3 and 4, a base assembly 100 of a press-fit device according to an embodiment of the present utility model includes a first mounting plate 120 and a sliding plate 130 slidably connected to the first mounting plate 120; the side of the sliding plate 130 facing away from the first mounting plate 120 is used to carry the motherboard. Since the sliding plate 130 for carrying the motherboard can slide with respect to the first mounting plate 120, when the motherboard needs to be mounted on the sliding plate 130 or when the motherboard needs to be detached from the sliding plate 130 after the heat sink 600 is assembled on the motherboard, the sliding plate 130 can be slid to the position shown in fig. 4, so that the motherboard is easily mounted to and detached from the sliding plate 130. It should be noted that, different sliding plates 130 adapted to the main board can be prepared according to the model of the main board, and when in use, different sliding plates 130 can be replaced according to the model of the main board, so that the adaptability of the press-fit device is stronger.

In one specific embodiment, the base assembly 100 further includes a guide rail 140 shown in fig. 4, the guide rail 140 is mounted on the first mounting plate 120, a sliding block matched with the guide rail 140 is mounted on the sliding plate 130, and the sliding block slides on the guide rail 140, so as to realize sliding of the sliding plate 130 relative to the first mounting plate 120.

When the heat sink 600 needs to be assembled to the motherboard, the motherboard is firstly mounted to the sliding board 130, and the second driving assembly 520 drives the mounting assembly 200 to approach the sliding board 130, so that the mounting assembly 200 moves to a preset mounting position; then placing the rivet-mounted heat sink 600 in the alignment hole 221 of the mounting member 220; such that the first mounting hole 610 on the heat sink 600 is opposite to the second mounting hole on the motherboard; the first driving assembly 510 drives the press-fitting assembly 300 to approach the sliding plate 130, so that the press-fitting portion 321 of the press-fitting assembly 320 at least partially extends into the alignment hole 221 and abuts against the rivet, and applies a pressing force to the rivet, so that the rivet moves downward along the first direction and passes through the second mounting hole on the motherboard, thereby completing the assembly of the heat sink 600 and the motherboard. Finally, the first driving assembly 510 drives the press-fit assembly 300 to move away from the sliding plate 130, the second driving assembly 520 drives the mounting assembly 200 to move away from the sliding plate 130, and the assembled motherboard, the heat sink 600 and the sliding plate 130 are separated.

The technical features of the above-described embodiments may be arbitrarily combined, and all possible combinations of the technical features in the above-described embodiments are not described for brevity of description, however, as long as there is no contradiction between the combinations of the technical features, they should be considered as the scope of the description.

The above examples illustrate only a few embodiments of the utility model, which are described in detail and are not to be construed as limiting the scope of the utility model. It should be noted that it will be apparent to those skilled in the art that several variations and modifications can be made without departing from the spirit of the utility model, which are all within the scope of the utility model. Accordingly, the scope of protection of the present utility model is to be determined by the appended claims.
