Embodiment

Please refer to Fig. 1, Fig. 2 and shown in Figure 3.Radiation fin assembly tool 10 of the present invention is in order to behind a mainboard 20 back side application of force certain hours, make the thermal grease on the mainboard 20 contact fully with the CSP assembly surface, the fin of CSP assembly is fixed on the mainboard 20, and described radiation fin assembly tool 10 comprises that mainly briquetting machine 102 and that a holder 101, is arranged at these holder 101 tops slides against the portable plate 103 on this holder 101 back and forth.

Wherein, described holder 101 1 sides are provided with the guide rail 1011 that dual-purpose slides back and forth for this portable plate 103, and this two guide rail 1011 is parallel to each other, and these holder 101 these sides are provided with one stroke switch 1012 near its lateral margin place.

In addition, described briquetting machine 102 is arranged at the side that this holder 101 is provided with guide rail 1011, and this briquetting machine 102 is across this two guide rails, 1011 both sides, and vertical mutually with guide rail 1011.

Please refer to shown in Figure 1ly again, be the decomposing schematic representation of this briquetting machine 102.Described briquetting machine 102 mainly comprises some axis of guides 1021, the one end is individually fixed on the air cylinder fixed plate 1023, and this air cylinder fixed plate 1023 is connected with a cylinder 1022, its other end correspondence passes said fixing seat 101 and is fixed on the fixed block 1024, again, plurality of fixed axle 1,028 one ends are individually fixed on this fixed block 1024, its other end is arranged with an elastic parts 1027 respectively and correspondence passes this fixed block 1024, and be fixed on the application of force piece 1025, in present embodiment, this elastic parts 1027 is a spring, in addition, this holder 101 is provided with some limited posts 1026, these limited post 1,026 one ends are individually fixed on this holder 101, its other end is stretched respectively and is placed between this holder 101 and this fixed block 1024, and this stretches the end put and this fixed block 1024 at a distance of certain distance, define the distance that cylinder 1022 pulling fixed blocks 1024 move up and down, since the cushioning effect of elastic parts 1027, certain power thereby 1022 pairs of application of force pieces 1025 of assurance cylinder are exerted pressure.

Again, described portable plate 103 slides against on the guide rail 1011 of this holder 101 back and forth, these portable plate 103 1 sides are provided with plurality of fixed groove 1031, and this holddown groove 1031 is in order to place band fin (not shown) to be assembled, and also be provided with some alignment pins 1032 on this side, the location was used when these alignment pin 1032 usefulness were positioned over this portable plate 103 for this mainboard 20, in addition, also be provided with leader 1033 on this portable plate 103, pull this handle 1033 and can make this portable plate 103 on the guide rail 1011 of this holder 101, slidably reciprocate.

Moreover described radiation fin assembly tool 10 also comprises a turning circuit, and this turning circuit is formed by above-mentioned travel switch 1012, a control switch 1013, a timing module 1014, a signal lamp and a cylinder 1022 series connection.

When need assembling fin, at first fin is positioned in the holddown groove 1031 of this portable plate 103, and mainboard 20 that will be to be assembled utilizes alignment pin 1032 to be fixed on this portable plate 103, and the side that this mainboard 20 is not provided with electronic building brick up, after fixing this mainboard 20, with this handle 1033 of hand push, make this portable plate 103 carry over guide rail 1011 and slide to this briquetting machine 102 belows, continue to promote this handle 1033, contact travel switch 1012 on the holder 101 until these portable plate 103 1 side impacts, make this turning circuit conducting, open this control switch 1013, at this moment, cylinder 1022 and air cylinder fixed plate 1023 thereof move downward in the lump, because the interconnect function of the axis of guide 1026, fixed block 1024 also moves downward with cylinder 1022 and air cylinder fixed plate 1023, thus extruding elastic parts 1027, to force on this application of force piece 1025, because the position-limiting action of limited post 1026, so, this application of force piece 1025 presses to mainboard 20, with certain pressure that mainboard 20 is exerted pressure, make thermal grease contact fully with the surface of CSP assembly, at this moment, time block 1014 picks up counting, after waiting to exert pressure 15 seconds, signal lamp is bright, and the operating personnel begins fin is installed blind rivet.

After installing, close this control switch 1013, cylinder 1022 and air cylinder fixed plate 1023 thereof move upward in the lump, because the interconnect function of the axis of guide 1026, fixed block 1024 also moves upward with cylinder 1022 and air cylinder fixed plate 1023, thereby the state that elastic parts 1027 is replied when not pushing, no longer force on this application of force piece 1025, so, this application of force piece 1025 is no longer suppressed this mainboard 20, at this moment, with this handle 1033 of hand propelled, this portable plate 103 is pulled out, take out mainboard 20 again, thereby finish assembling the fin on this mainboard 20.
