Description
Technical field
This utility model belongs to spot gluing equipment field, particularly to a kind of dispensing needle head.
Background technology
Dispensing needle head i.e. puts the syringe needle that glue syringe top can arbitrarily be loaded and unloaded, the specification of dispensing needle head the most all than
Less, and color and of a great variety.Along with the development of various gluing process, the requirement to dispensing needle head is more and more higher, puts glue
Precision not only determined by glue dispensing valve, a glue effect can be produced a very large impact by the precision of dispensing needle head equally, particularly exists
The trace point glue industries such as SMT, LED, optical communication, semiconductor manufacturing, medicine.
At present, glue-dispensing needle head structure used on traditional point gum machine as shown in Figure 1, is divided into needle section 01, connecting portion
02 and the glue channel 03 of transfixion pin head 01 and connecting portion 02.This dispensing needle head is fixing even by connecting portion 02 and point gum machine
Connect.Needle section 01 is open column shape structure, and needle section 01 one end is glue outlet 04.In this dispensing needle head, glue exports 04 section
Face is the circle of rule, and glue to export the diameter of section at 04 identical with the diameter of section of glue channel 3.
After using this dispensing needle head point glue, as shown in Figure 2, for D-section, bottom, cross section is divided in the cross section of gained adhesive tape
Rectangle, top is divided into semicircle.This D-section has the disadvantages that 1. adhesive tape are easily deformed；2., when adhesive tape height is higher, hold
Easily subside.Therefore, in order to make the adhesive tape of D-section reach required height, it is sometimes desirable to putting glue several times, operation is the most multiple
Miscellaneous.
It is well known, however, that the glue of same volume, the height of the adhesive tape of some glue gained is the highest, the sealing of adhesive tape
Property is the best, and conductive effect is the best.
Utility model content:
It is an object of the invention to overcome the shortcoming of prior art, it is provided that a kind of dispensing needle head, it is when glue, and adhesive tape is steady
Admittedly be unlikely to deform, and when put adhesive tape height is higher, it is difficult to subside, and glue quantity can be reduced.
For solving the problems referred to above, this utility model provides techniques below scheme: a kind of dispensing needle head, including needle section and
Described needle section connect connecting portion and run through described needle section and the glue channel of described connecting portion, described needle section one
End exports for glue, and the outlet of described glue is axially arranged, and the outlet of described glue is wedge structure, exports institute's point by described glue
Adhesive tape, its cross section is triangle.
Further, the outlet of described glue is provided with a slant cutting edge, and described slant cutting edge is located at the outlet of described glue and institute
State angle α formed by the axis of the junction of needle section side, described slant cutting edge and described dispensing needle head and be 20-40 °.
Further, described angle α is 25-35 °
Preferably, described glue channel is a cylindrical cavity, a diameter of 1-2mm of its cross section.
Preferably, the minimum diameter of the cross section of described glue outlet is 0.5-1mm.
Preferably, described needle section is hollow columnar structures.
Preferably, dispensing needle head is metal material or rigid plastics is made.
The beneficial effects of the utility model:
Dispensing needle head in this utility model, the outlet of its glue is wedge structure, is provided with a slant cutting edge, and slant cutting edge sets
In the junction of glue outlet with needle section side, slant cutting edge becomes angle a with the axis of dispensing needle head, is so designed that, passes through
The optimization that the glue of dispensing needle head is exported so that put adhesive tape cross section is the adhesive tape of triangular-section, so, triangular-section
Adhesive tape relative to the adhesive tape of D-section, its top is less, and bottom is relatively big, such structure, and the adhesive tape making triangular-section is stable
Property relatively big, be unlikely to deform and subside；Further, time specifically used, the glue of same volume, the adhesive tape of triangular-section is relative to D
The adhesive tape of tee section, the adhesive tape height that can reach is higher, and more preferably, conductive effect is the most more preferably for sealed vol；The more important thing is, triangle
The adhesive tape of tee section reaches identical height relative to the adhesive tape of D-section, adhesive tape to be made, needed for the adhesive tape of triangular-section
Glue quantity is less, thus saves glue, reduces cost.

Detailed description of the invention
Embodiment: as it is shown on figure 3, present embodiments provide the specific embodiment of a kind of dispensing needle head, this dispensing needle head bag
Including the needle section 1 of hollow columnar, needle section 1 one end connects connecting portion 2.This dispensing needle head also includes transfixion pin head 1 and connects
Connect the glue channel 3 in portion 2, for the circulation of glue.Glue channel 3 is the cavity of a cylindrical shape, and its diameter range is
1-2mm.In the present embodiment, its cross-sectional diameter is 1.65mm.
One end of needle section 1 is axially arranged glue outlet 4, and in the present embodiment, glue outlet 4 is wedge structure, its
Outer diameter is little, and inner end diameter is big, and the maximum gauge of inner end is identical with glue channel 3, for 1.65mm.
Wedge structure realizes by arranging a slant cutting edge 5 in glue outlet 4, and this slant cutting edge 5 is located at glue outlet 4
Junction with needle section 1 side.Further, when angle α formed by the axis β of slant cutting edge 5 and dispensing needle head is 25-35 °, institute
The adhesive tape performance obtained is preferable, and the minimum diameter of now glue outlet 4 is 0.5-1mm.
In the present embodiment, when angle α is 30 °, a diameter of 0.825mm of glue outlet outer end, it is glue channel 3
Half.
Connecting portion 2 includes the interface 6 for connecting with point gum machine, and interface 6 can also be set to multiple as required, can
Think screw socket, bayonet socket etc..
This dispensing needle head uses metal material or rigid plastics to make, and is preferably stainless steel in the present embodiment, because of
Higher for rustless steel dispensing needle head quality, last a long time.
When making this dispensing needle head, in order to not affect a glue effect, the facet of slant cutting edge 5 must keep smooth, nothing
Burr or foreign body.
When using this dispensing needle head, the cross section of the adhesive tape pointed out as shown in Figure 4, for triangle, this triangular-section
Adhesive tape has identical height with the adhesive tape of the D-section in Fig. 2.The adhesive tape top of triangular-section is less, and bottom is relatively big, as
This structure so that it is stability is relatively big, is unlikely to deform and subsides.And, although two kinds of adhesive tape reach identical height, by difference portion
Identical sealed vol and electrical efficiency can be reached after part bonding, but the glue quantity needed for the adhesive tape of triangular-section is less,
Thus save glue, reduce cost.
Certainly above-described embodiment is only for illustrating technology of the present utility model design and feature, its object is to allow and is familiar with this
The people of technology will appreciate that content of the present utility model and implements according to this, can not limit protection model of the present utility model with this
Enclose.All equivalent transformations done according to the spirit of this utility model main technical schemes or modification, all should contain in this reality
Within novel protection domain.
