Description

The hot melt tool

Technical field

The present invention relates to a kind of hot melt tool, especially a kind ofly carry out reaming, and the hot melt tool of reusable plastic.

Background technology

In the prior art, the assembling of notebook computer internal structure if desire engages its constructional iron with plastic, generally all is to use the hot melt rod structure.Please refer to Fig. 1, be the hot melt post of prior art and the schematic diagram of hot melting connector.Hot melt post 100 protrudes from ironware 92, protrudes from the heating pressurized of ironware 92 hot melt post 100 outward via fixture, and is configured as the hot melting connector 80 with fixed engagement ironware and plastic effect.

But, after in a single day this hot melt structure heats pressurized and be shaped, want constructional iron is done (made preproduction when for example researching and developing) when changing, just to remove hot melting connector, its plastic is separated with ironware.When plastic with after ironware separates, remaining hot melt post 100 with arround ironware substantially flush, thereby not have enough highly hot melt post with the shaping hot melting connector.Therefore, plastic certainly will cause damage and must will scrap plastic less than the value of recycling.

Therefore, be necessary to provide a kind of hot melt tool, to improve the existing problem of prior art.

The specific embodiment

For above-mentioned and other purposes, feature and advantage of the present invention can be become apparent, cited below particularlyly go out specific embodiments of the invention, and cooperate appended accompanying drawing, be described in detail below.

Please in the lump with reference to figure 2 and Fig. 3, Fig. 2 is the exploded view of hot melt tool of the present invention, the cutaway view when Fig. 3 carries out reaming for hot melt tool of the present invention.

Hot melt tool 1 of the present invention is used for hot melting connector 80 (as shown in Figure 1) and is removed the remaining hot melt post 82 in back, and hot melt post 82 has blind hole 200.Since this moment hot melt post 82 height deficiency, can't be in traditional heating pressurized mode with hot melt post 82 to form hot melting connector.

Hot melt tool 1 of the present invention mainly comprises base 10, probe 20 and fixture 30.Wherein, base 10 comprises first end 11, second end 12 and through hole 13, and through hole 13 is connected to second end 12 by first end 11, and through hole 13 can be sheathed on the hot melt post 82 by second end 12.Therefore, the internal diameter of base 10 is more than or equal to the external diameter of hot melt post 82.In the present embodiment, the internal diameter of base 10 is designed to the external diameter 0.1mm greater than hot melt post 82.

Because the structure that the periphery of hot melt post 82 often has a reinforced ribs 60 (as shown in Figure 2, hot melt post 82 sides have three and are vertical reinforced ribs 60 mutually), in order not influence the carrying out that base 10 is inserted in hot melt post 82, in the present embodiment, second end 12 at base 10 also comprises a plurality of grooves 121, and its space promptly supplies ccontaining reinforced ribs 60.In the present embodiment, the quantity of a plurality of grooves 121 is four, and it is evenly distributed in second end of base 10, that is every 90 degree a groove 121 is just arranged.

Probe 20 comprises the 3rd end 21, the 4th end 22, reamer 23 and location division 24.The 4th end 22 of probe 20 is inserted through hole 13 by first end 11 of base 10.

Reamer 23 is positioned at the 4th end 22, and reamer 23 can produce a reaming 822 with this hot melt post 82.Furthermore, after heated probe 20, heat is passed to reamer 23, can enlarge the blind hole 200 on the hot melt post 82 during reamer 23 contact hot melt posts 82, and form the reaming 822 (as shown in Figure 3) identical or bigger than the aperture of former blind hole 200 (as shown in Figure 2) on hot melt post 82.In the present embodiment, the external diameter of the reamer 23 of probe 20 is designed to greater than hot melt post 82 internal diameters (being blind hole 200) 0.1mm.

Location division 24 is between the 3rd end 21 and the 4th end 22, and location division 24 purposes can be accurately positioned when being to form reaming 822 processes, guarantees that probe 20 vertically enters the through hole 13 of base 10, and avoids crooked.In the present embodiment, location division 24 is plate-like, and the external diameter of location division 24 is less than or equal to the aperture of through hole 13.In the present embodiment, location division 24 is designed to the aperture 0.1mm of its external diameter less than through hole 13.Just the structure and the size of location division 24 are not limited to above-mentioned.

Then please in the lump with reference to figure 4 and Fig. 5.Fig. 4 is the stereogram of fixture, the schematic diagram when Fig. 5 inserts reaming for fixture.After reaming 822 is finished, re-use fixture 30 and be used for fixing hot melt post 82 (the hot melt post is the part of plastic) and ironware 92.In the present embodiment, fixture 30 is a hot melt drawing pin, and its material can be designed to metal material or plastic material according to demand, and just the structure and the material of fixture 30 are not limited to this.

The hot melt drawing pin comprises cylinder 32 and compresses body 34.Cylinder 32 is taper, makes more or less freelyly when cylinder 32 leading portions enter reaming 822, and back segment cylinder 32 is when entering reaming 822, reaming 822 interference engagement of the starting taper structure of hot melt drawing pin and hot melt post 82, and the hatched example areas of the zone of interference engagement such as Fig. 5.When cylinder 32 enters reaming 822 fully, compress body 34 and can press on ironware.Have gap d between the head periphery of hot melt drawing pin and the ironware 92, this gap d helps the user to dismantle fixture 30.

Comprehensively above-mentioned, on the model product when hot melt tool 1 of the present invention can extensively be used in R﹠D process, can keep former plastic when helping development, change the ironwares of difference test usefulness easily, reduce R﹠D costs and the function of verifying fast to reach.In addition, hot melt tool 1 can be used in production, reaches the plastic cost when saving the production process heavy industry, and reduces the problem of scrapping, to improve the production qualification rate.

To sum up institute is old, and no matter the present invention everywhere all shows it totally different in the feature of known technology with regard to purpose, means and effect, earnestly asks the auditor to perceive, and grants quasi patent early, makes Jiahui society, and the true feeling moral just.Only it should be noted that above-mentioned many embodiment give an example for convenience of explanation, the present invention's interest field required for protection should be as the criterion so that the scope of claims is described naturally, but not only limits to the foregoing description.
