[0026] In order to facilitate the understanding of the present invention, the present invention will be described in more detail below with reference to the accompanying drawings, in which preferred embodiments of the present invention are shown.

[0027] like Figures 1 to 3As shown, a radiator copper nail riveting device 10 includes a base 110 and a press assembly 200. The base 110 is provided with a carrier plate 120 for supporting the radiator 21. The press assembly 200 includes a riveting driver 210, a riveting block 220, a positioning plate 230 and a plurality of pressing pins 240. The positioning plate 230 is provided with a plurality of positioning holes 231. Each positioning hole 231 is used to receive a copper nail 22. The positioning plate 230 is detachably covered on the radiator 21. , so that each positioning hole 231 is aligned with each reserved hole 21a respectively, the riveting driving component 210 is set on the machine base 110, the riveting block 220 is set on the output shaft of the riveting driving component 210, and each pressing pin 240 is set on the riveting block 220, and each pressing pin 240 is aligned with each positioning hole 231 respectively. The riveting driving component 210 is used to drive the riveting block 220 to descend, so that each pressing pin 240 pushes each copper nail 22 respectively to be pressed into each reserved hole 21a one by one.

[0028] It should be noted that the carrier plate 120 is fixed to the base 110 by screws. For example, the carrier plate 120 can be made of bakelite or an aluminum profile. The carrier plate 120 is used to support the radiator 21. Therefore, different carrier plates 120 can be replaced according to the size of the radiator 21. After the radiator 21 is placed on the carrier plate 120, the positioning plate 230 is placed on the radiator 21 so that each positioning hole 231 on the positioning plate 230 is connected and aligned with each reserved hole 21a. A copper nail 22 is then placed in each positioning hole 231. The copper nail 22 is positioned through the positioning hole 231. Then, when the riveting drive 210 drives the riveting block 220 to descend, the pressing pins 240 press the copper nail 22 in each positioning hole 231 into the reserved hole 21a of the radiator 21. For example, the riveting drive 210 is a cylinder. In this way, the pressing depth of each copper nail 22 relative to the heat sink 21 is consistent, and the copper nail 22 is limited by the positioning hole 231 to prevent the copper nail 22 from tilting and bending during the pressing process. In addition, each copper nail 22 can be pressed into the heat sink 21 synchronously, effectively improving the efficiency and quality of riveting the copper nail 22 into the heat sink 21.

[0029] like Figure 1 As shown, in one embodiment, a plurality of limiting blocks 130 are detachably provided on the carrier plate 120 , and each limiting block 130 is used to abut against the heat sink 21 .

[0030] It should be noted that to ensure rapid loading of the heat sink 21 and alignment of the pre-set holes 21a on the heat sink 21 with the press pins 240, a plurality of stoppers 130 are mounted on the carrier plate 120. The stoppers 130 define an area for the heat sink 21, allowing for rapid and accurate positioning of the heat sink 21 during unloading.

[0031] In one embodiment, the stopper 130 is bonded to the carrier plate 120. For example, a viscous layer is coated on one sidewall of the stopper 130, and the viscous layer is used to bond and secure the stopper 130 to the carrier plate 120. In this way, the size of the area enclosed by each stopper 130 can be adjusted according to the actual size of the heat sink 21, providing good fixing compatibility for heat sinks 21 of different sizes.

[0032] like Figure 2 and Figure 4 As shown, in one embodiment, a mounting groove 21b is further provided on the heat sink 21, and a positioning protrusion 250 is provided on the positioning plate 230. When the positioning plate 230 covers the heat sink 21, the positioning protrusion 250 is adaptively accommodated in the mounting groove 21b.

[0033] It should be noted that, in order to maintain good contact with components such as chips, thereby better dissipating heat from the components, the heat sink 21 is provided with mounting grooves 21b. Furthermore, to ensure that the positioning plate 230 is quickly and accurately placed on the heat sink 21, a corresponding positioning bump 250 is provided on the positioning plate 230. The positioning bump 250 and the mounting groove 21b are adapted to fit together, allowing the positioning plate 230 to be quickly and accurately fastened to the heat sink 21, ensuring that each positioning hole 231 is aligned with each reserved hole 21a.

[0034] like Figure 1 and Figure 3 As shown, in one embodiment, the pressing assembly 200 also includes a guide rod 260 and an adjusting block 270. The adjusting block 270 is arranged on the output shaft of the riveting driving member 210. The guide rod 260 is slidably installed on the machine base 110 along the vertical direction, and one end of the guide rod 260 is connected to the adjusting block 270.

[0035] It should be noted that in order to improve the stability of the rivet block 220 when driving the pressing pins 240 to perform the lifting motion, thereby reliably and stably pressing the copper nails 22 into the reserved holes 21a of the heat sink 21, a guide rod 260 and an adjustment block 270 are provided to guide the rivet block 220. Specifically, one end of the adjustment block 270 is fixedly connected to the output shaft of the rivet driver 210, and the guide rod 260 is mounted on the machine base 110 via a linear bearing, and one end of the guide rod 260 is connected to the adjustment block 270.

[0036] like Figure 1 As shown, in one embodiment, a waist-shaped hole 271 is formed on the adjustment block 270 , and one end of the guide rod 260 is inserted into the waist-shaped hole 271 .

[0037] In this way, when the position of the riveting block 220 relative to the output shaft of the riveting driving component 210 is adjusted, the riveting pressure on the copper nail 22 when the riveting block 220 drives each pressing needle 240 to press down can be adjusted. When the position of the riveting block 220 relative to the output shaft of the riveting driving component 210 is adjusted, in order to ensure a stable connection between the adjusting block 270 and the guide rod 260, a waist-shaped hole 271 is opened on the adjusting block 270. In this way, after the guide rod 260 passes through the waist-shaped hole 271, it is tightened and fixed by screws.

[0038] like Figure 1 and Figure 3 As described, in one embodiment, the press-fitting assembly 200 further includes a sleeve 281 and two locking nuts 282. The output shaft of the riveting driver 210 is sequentially passed through the adjusting block 270, the sleeve 281, and the riveting block 220. The two locking nuts 282 are both screwed onto the output shaft of the riveting driver 210, and one of the two locking nuts 282 abuts against the adjusting block 270, and the other abuts against the riveting block 220, so that the two locking nuts 282 lock and fix the adjusting block 270, the sleeve 281, and the riveting block 220.

[0039] It should be noted that in order to facilitate adjustment of the relative position of the rivet block 220 and the output shaft of the rivet driver 210, two locking nuts 282 are provided that are screwed onto the output shaft of the rivet driver 210. The two locking nuts 282 are used to clamp and secure the rivet block 220, the sleeve 281, and the adjustment block 270. This also facilitates adjustment of the position of the adjustment block 270 and the output shaft of the rivet driver 210.

[0040] like Figure 1 and Figure 3 In one embodiment, a mounting hole 221 is provided on the riveting block 220 , and the pressure pin 240 is inserted into the mounting hole 221 . A plurality of fastening screws 290 are screwed laterally on the riveting block 220 , and each fastening screw 290 is used to jointly press the pressure pin 240 .

[0041] It should be noted that the insertion holes 221 are distributed along the vertical direction on the riveting block 220. In this way, the pressure pin 240 is pressed together by multiple fastening screws 290, so that the position of the pressure pin 240 relative to the riveting block 220 can be quickly adjusted. Therefore, different pressure pins 240 can be replaced according to actual needs.

[0042] The above-described embodiments merely represent several implementations of the present invention. While the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that a person skilled in the art would be able to make various modifications and improvements without departing from the concept of the present invention, and these modifications and improvements fall within the scope of protection of the present invention. Therefore, the scope of protection of the present utility model patent shall be determined by the appended claims.
