Detailed description of the invention
For enabling above-mentioned purpose of the present invention, feature and advantage become apparent more, and below in conjunction with the drawings and specific embodiments, the present invention is further detailed explanation.
Alleged herein " embodiment " or " embodiment " refers to special characteristic, structure or the characteristic that can be contained at least one implementation of the present invention.Different local in this manual " in one embodiment " occurred not all refers to same embodiment, neither be independent or optionally mutually exclusive with other embodiments embodiment.
Refer to Fig. 1, it is the Glue dripping head device structural representation in one embodiment in the present invention, the adapter 2 that described Glue dripping head device comprises Glue dripping head 1 and is connected with described Glue dripping head 1.
Refer to Fig. 2, it is the Glue dripping head structural representation in one embodiment in the present invention, and described Glue dripping head 1 has the first through hole 12, and described first through hole 12 runs through whole Glue dripping head 1.In this embodiment, described Glue dripping head 1 is plastic conical Glue dripping head, and the length of described Glue dripping head 1 is 32mm, and described Glue dripping head 1 end is provided with external screw thread 11, and this external screw thread 11 is for being connected with adapter 2.
Refer to Fig. 3, it is the adapter structural representation in one embodiment in the present invention.Described adapter 2 has the second through hole, and this second through hole comprises Part I 222 and Part II 232.Described adapter 2 also comprises the first connecting portion 21, intermediate handle part 22 and the second connecting portion 23, and described second through hole runs through described first connecting portion 21, intermediate handle part 22 and the second connecting portion 23, described second through hole and the first through hole 12 coaxial communication.
Please continue to refer to Fig. 1 to 3, described first connecting portion 21 has female thread structure 211, adapter 2 and described Glue dripping head 1 can be sealed connected together by this female thread structure 211.Described second connecting portion 23 has external thread structure 231, adapter 2 and outer hose (not shown) can be tightly connected by this external thread structure 231.When adapter 2 is when being connected with Glue dripping head 1 and outer hose, intermediate handle part 22 can ensure the axiality of adapter 2 and Glue dripping head 1 and outer hose connecting portion, to play good sealing function as grip portions.In this embodiment, the length L1 of described first connecting portion 21 is 17.7mm, and the length L2 of intermediate handle part 22 is 11.8mm, and the length L3 of described second connecting portion 23 is 7.2mm.The total length of described first connecting portion 21, intermediate handle part 22 and the second connecting portion 23 is 36.7mm, and the total length L after described Glue dripping head 1 is connected with adapter 2 is 64mm.In other embodiments, the length of described first connecting portion 21, intermediate handle part 22 and the second connecting portion 23 is not limited, as long as meeting the total length after being connected with described Glue dripping head 1 is 64mm.In other embodiments, require to adjust the total length L after adapter 2 connects Glue dripping head 1 according to load and some glue, make total length L be greater than 64mm or be less than 64mm, to meet actual needs.
Described Part I 222 is cylindrical, and this columniform internal diameter φ 1 is 2.4mm.Described Part II 232 is infundibulates that arrogant mouth successively decreases to osculum diameter, and the large mouth diameter phi 3 of described Part II 232 is 4.4mm, and the osculum diameter phi 2 of described Part II 232 is 3.8mm.When carrying out glue load, first glue entered in Part II 232 by the big opening end of Part II 232, and then enter in Part I 222, finally flows out in the first through hole 12 of Glue dripping head 1 again.Because glue is when entering adapter 2, adapter 2 inwall can affect the flowing of glue due to the effect of frictional force, and this Part II 232 can make glue enter smoothly in the less cylindrical hole of internal diameter 222.In this embodiment, the large mouth diameter of Part II 232 is 4.4mm, and the osculum diameter of described Part II 232 is 3.8mm.The funnel shaped structural design that arrogant like this mouth to osculum diameter successively decreases, can make the inwall frictional force that glue contacts with adapter 2 when glue flows in Part II 232 reduce, and makes glue flow evenly simultaneously.In other embodiments, the large mouth diameter of described Part II 232 and osculum diameter are not limited, can adjust according to actual needs.In one embodiment, the external diameter φ 4 of described second connecting portion 23 is 7.5mm, error ± 0.5mm.In other embodiments, the external diameter of the second connecting portion 23 is not limited, with to be connected with outer hose be sealed into suitable.In the present invention, the internal diameter of adapter the experiment proved that its plastic emitting effect is enough to meet the picture glue requirement of pressure sensor.
In the present invention when not affecting plastic emitting and load effect, the length of Glue dripping head and adapter can suitably adjust.
Point glue equipment of the present invention is not only applicable to the higher silica gel of viscosity, is also applicable to the various adhesive for encapsulating paster.
Assembling process of the present invention is as follows: the first connecting portion 21 first Glue dripping head 1 being aimed at adapter 2 screws, then the second connecting portion 23 of adapter 2 is aimed at outer hose to screw again, when pressure sensor carries out load, first glue enter adapter 2 by outer hose, and then flowed out by Glue dripping head 1, achieve load point glue.
Glue dripping head device of the present invention, is connected with plastics Glue dripping head by adapter, and total length is 64mm, avoids glue plastic emitting problem slowly when glue drawn by pressure sensor load, significantly improves load efficiency simultaneously.
It is pointed out that the scope be familiar with person skilled in art and any change that the specific embodiment of the present invention is done all do not departed to claims of the present invention.Correspondingly, the scope of claim of the present invention is also not limited only to previous embodiment.
