Description

[0001] The utility model relates to the technical field of radiator assembly, and more particularly to a press-fit device based on a radiator thermal pad. Background Art

[0002] At present, with the development of electronic products, there is an increasing demand to integrate multiple devices on a single motherboard. There are more and more heat-generating electronic devices on the motherboard. In order to avoid affecting the performance, the heat dissipation of these heat-generating electronic devices is extremely important. The demand for radiators is becoming more and more important. Among them, thermal pads play a vital role in radiators, which can transfer the heat on the chip to the radiator with the highest efficiency.

[0003] When assembling traditional radiators, thermal pads are manually attached by hand and then pressed by hand. However, the force of manual pressing is not uniform, resulting in the thermal pad not being well attached to the radiator, and also causing debris on the hands to stick to the thermal pad. If the thermal pad has a large area, the pressing needs to be repeated many times, especially for thermal pads made of phase change materials. After taking them out of the cold storage room, it is difficult for manual pressure to be applied evenly during attachment due to the characteristics of the phase change material, resulting in reduced production efficiency and poor or damaged thermal pads.

[0004] Therefore, a new solution needs to be proposed to solve this problem. Utility Model Content

DETAILED DESCRIPTION

[0021] In order to more clearly understand the technical means of the present invention and implement it according to the contents of the specification, the specific implementation methods of the present invention are further described in detail below in conjunction with the drawings and examples. The following examples are used to illustrate the present invention but are not used to limit the scope of the present invention.

[0022] A press-fit device based on a heat sink thermal pad, such as Figure 1 and Figure 2 As shown, it includes a base 1, and a plurality of positioning components for limiting the position of the product are distributed in an array along the width direction on the top of the base 1. A pressure plate 321 is movably connected to the top of the positioning component along the vertical direction. The positioning component includes a plurality of positioning members 4 movably connected along the horizontal direction. The product is placed between the plurality of positioning members 4. A support frame 2 is fixedly connected to the top of the base 1 on one side of the positioning component, and a driving structure for driving the pressure plate 321 to reciprocate in the vertical direction is provided on the support frame 2.

[0023] The side of the support frame 2 facing the positioning assembly is fixedly connected with an adjustment plate 21 by bolts, and a long strip-shaped adjustment slot is opened on the support frame 2, and the length direction of the adjustment slot is vertically arranged. The adjustment plate 21 is inserted into the adjustment slot by bolts and fixedly connected, so that the adjustment plate 21 can be fine-tuned in the vertical direction. The side of the adjustment plate 21 facing away from the support frame 2 is fixedly connected with the support plate 3 by bolts. The driving structure includes a driving member 32 and a cylinder 31 vertically arranged on the top of the support plate 3. The output end of the cylinder 31 passes through the support plate 3 and is fixedly connected to the top of the driving member 32. The pressing plate 321 is fixedly connected to the bottom of the driving member 32. By driving the cylinder 31, the driving member 32 is driven to move, thereby driving the pressing plate 321 to press toward the product. The cam 332 is provided with a plurality of guide pins 321 and a plurality of guide pins 322, and the plurality of guide pins 322 are provided with plurality of guide pins 323. The plurality of guide pins 321 are provided with plurality of guide pins 324. The plurality of guide pins 322 are provided with plurality of guide pins 325.

[0024] The base 1 is provided with a plurality of movable grooves 11 arranged in an array along its width direction. The length direction of the movable groove 11 is consistent with the length direction of the base 1. A movable rod 41 is provided on the positioning member 4 and passes through the movable groove 11. The movable rod 41 is detachably connected to the positioning member 4 by a bolt. A embedding groove 12 is provided at the bottom of the base 1. The movable groove 11 is provided in the embedding groove 12. One end of the movable rod 41 passing through the movable groove 11 is threadedly connected with a nut 411. The nut 411 conflicts with the inner bottom wall of the embedding groove 12, and the outer peripheral wall of the nut 411 conflicts with the inner side wall of the embedding groove 12. A groove 42 is provided at the top of the positioning member 4. A waist-shaped hole is provided on the inner bottom wall of the groove 42 for the movable rod 41 to pass through. The head of the movable rod 41 conflicts with the inner bottom wall of the groove 42, and the cross-section of the groove 42 is also waist-shaped. By providing the embedding groove 12, the outer peripheral wall of the nut 411 conflicts with the inner side wall of the embedding groove 12, which can limit the nut 41 1 has a rotational freedom, so that the nut 411 is relatively fixed in the embedded groove 12. At this time, rotating the movable rod 41 can make the movable rod 41 move in the vertical direction, so as to approach or move away from the inner bottom wall of the groove 42, thereby realizing the loosening and fixing of the positioning member 4. When loosening, the positioning member 4 can be adjusted, and the distance between two adjacent positioning members 4 can be adjusted to adapt to products of different specifications, thereby expanding the scope of application; and the thickness of the head of the movable rod 41 is less than the depth of the groove 42. The movable rod 41 can adopt a hexagon socket bolt, which can completely accommodate the head of the movable rod 41 in the groove 42 without protruding from the positioning member 4, so that the top surface of the positioning member 4 remains flat. When the product is thin and the cylinder 31 does not move enough, and the pressure plate 321 cannot contact the product, the position of the positioning member 4 is adjusted and the product is placed on the top of the positioning member 4. The positioning member 4 can also play a role of padding, thereby further expanding the scope of application.

[0025] Working principle: Loosen the movable rod 41, adjust the distance between adjacent positioning parts 4 in the same movable groove 11, place the product to be pressed between the positioning parts 4, and the positioning parts 4 are located on both sides of the product, thereby limiting the horizontal displacement of the product, achieving a good positioning effect, and better ensuring that the product is located under the pressing plate 321; after placing the thermal pad on the product, drive the cylinder 31 to drive the driving part 32 to move toward the product, and drive the pressing plate 321 to move toward the product until the thermal pad on the surface of the product is pressed, so that the thermal pad can be more stably bonded to the product, making the bonding more firm, and no manual pressing is required, saving time and effort, and improving work efficiency.

[0026] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. It should be pointed out that ordinary technicians in this technical field can make several improvements and modifications without departing from the technical principles of the present invention. These improvements and modifications should also be regarded as within the scope of protection of the present invention.
