Description
Technical field
The present invention relates to electronic equipment manufacture field, especially a kind of soft dispensing needle head.
Background technology
Dispensing needle head is the syringe needle that dispensing syringe top can be loaded and unloaded arbitrarily, the point applied to electronic equipment manufacture field
The specification of needle head is in general all smaller, between 14G-35G.Distinguished from material, can be simply by syringe needle area
It is divided into hard metal syringe needle and flexible plastic syringe needle.Because hard metal syringe needle easily scratches workpiece surface in use,
So consider typically to select flexible plastic syringe needle from outward appearance angle.
With the development of science and technology and the demand of user, electronic equipment particularly mobile phone develops towards frivolous direction.So
One, the space of electronic equipment internal is just more and more narrower and small.It is that one of application scenarios of dispensing needle head are illustrated referring to Fig. 1
Figure.Wherein, flexible PCB 11 is connected with upper glass 12 by the viscose glue of bonding pad 14, due to upper glass 12 simultaneously with lower glass 13
Connection, then working space of the dispensing needle head dispensing in bonding pad 14 is just quite narrow and small.And traditional plastic cement syringe needle is ensureing plastic emitting stream
On the basis of smooth, the contour machining procedure of material is limited by, the internal-and external diameter of syringe needle can not be made small as metal needle.
The content of the invention
The embodiment of the present invention provides a kind of soft dispensing needle head, to solve in the prior art on not scratching products surface
Under the premise of, it is difficult to the problem of dispensing is completed in narrow and small dispensing space.
A kind of soft dispensing needle head provided in an embodiment of the present invention, including：Enter glue end and glue-extruding end, it is described enter glue end and institute
State glue-extruding end and turn on to be formed and lead glue passage, the glue-extruding end is provided with breach, the breach bag along the dispensing needle head length direction
Cut surface is included, the breach forms out glue groove with the glue passage of leading.
Soft dispensing needle head provided in an embodiment of the present invention, by going out the setting of glue groove, syringe needle is made into the half-open of trough of belt
Formula form is put, not only improves the processing of plastic cement syringe needle, also allows for inserting the needle into use inside crack, injected
Glue can be along going out glue groove flowing in journey, and syringe needle is softer is not easy scratching products.
