A kind of automatic glue dispensing mechanism
Technical field
The present invention relates to electronic circuit dispensing technology field, a kind of automatic glue dispensing mechanism.
Background technology
In industrial production, some glue process is the most extensively used, especially electronic circuit, electric elements etc.
Local.At present, although spot gluing equipment is the most highly developed, but only rest on and allow glue smoothly, naturally
Flowing out from syringe needle, and the glue remaining on syringe needle all can be had every time after putting glue to overflow, this is to be avoided
, also it is the problem that a glue effect is had tremendous influence, as shown in Figure 1.Therefore, can only rely at present manually
The glue that erasing is overflowed, and this process needs the time of staying certain to equipment, and it is clean to be difficult to erasing.With
Time, due to artificial rubber, make syringe needle there is the biggest hidden danger being bent over, have a strong impact on a glue effect.
Therefore, strong influence speed of production and product quality, it is unfavorable for high efficiency production.
Summary of the invention
Overflow the problem of glue for solving syringe needle in prior art, it is an object of the invention to provide a kind of automatic dispensing machine
Structure.
Be the technical scheme is that by realizing the purpose of invention
A kind of automatic glue dispensing mechanism, including a work top, described work top one center line extends through
It is installed with track base, cylinder, some sebific duct seat and recovery capsule;Being slidably equipped with guide rail in described track base, this is led
Rail fixes with rubber plate that seat one side is fixing to be connected;Seat opposite side fixed by the piston rod of described cylinder and rubber plate
Face is fixing to be connected;It is installed with dispensing needle head on described some sebific duct seat;Described recovery capsule is by flexible pipe and inhales glue
Syringe needle is connected with rubber plate;Described rubber plate is fixed and is installed with rubber plate on seat, and this rubber plate top is sheathed on
On dispensing needle head.
The invention have the advantage that
1, present invention seek to address that the excessive glue problem of dispensing needle head, fully achieve the merit of automatically dropping glue, rubber
Can, substantially increase rubber quality and speed, the glue that recoverable overflows simultaneously, both improve production
Efficiency, has also liberated input of labor, has saved production cost simultaneously, eliminates the artificial safety to equipment
Hidden danger, well ensure that a colloid amount.
2, the present invention take the lead in solving in the same industry cannot automatically rubber problem, and for artificial,
Substantially increase rubber quality and speed, it is ensured that the quality of product and production capacity, also greatly reduce equipment event
Barrier hidden danger and the potential safety hazard of operating personnel, saved the resources of production simultaneously.

Detailed description of the invention
The present invention is described in more detail for 2-5 and reference below in conjunction with the accompanying drawings.
A kind of automatic glue dispensing mechanism, including a work top 6, described work top 6 one center line passes through respectively
Fasten and be provided with track base 11, cylinder 9, some sebific duct seat 7 and recovery capsule 8;
Being slidably equipped with guide rail 10 in described track base 11, it is fixing even that seat 5 one side fixed by this guide rail 10 and rubber plate
Connect;
The piston rod 4 of described cylinder 9 fixes with rubber plate that seat 5 another side is fixing to be connected;
At least one dispensing needle head 1 it is installed with on described some sebific duct seat 7;
Described recovery capsule 8 is connected with rubber plate 3 by flexible pipe and suction needle head 2;
Described rubber plate is fixed and is installed with rubber plate 3 on seat 5, and this rubber plate 3 top is sheathed on dispensing needle head 1.
Described rubber plate 3 is rounded triangle plate, and rubber plate 3 drift angle end is provided with the pin run through for dispensing needle head 1
Hole, this pin hole is correspondingly arranged with syringe needle 1 quantity and position, and the corresponding base of rubber plate 3 is provided with solid with rubber plate
The fixing hole that reservation 5 connects.
The top of described rubber plate 3 pin hole is provided with the interior chamfering 12 being easy to collect glue, forms bowl structure, under
Portion is cavernous structure.
Syringe needle 1 can be as desired to select single needle or spininess.
Suction glue hole is offered on the sidewall of described rubber plate 3 top.
Suction glue hole on the sidewall of described rubber plate 3 top extends internally and connects formation appearance glue chamber 13 with pin hole.
Described suction glue hole is affixed with suction needle head 2, and this suction needle head 2 is connected with reclaiming capsule 8 by flexible pipe 12.
Seat 5 fixed by described rubber plate is to be inverted L-shaped structure, and one side opening is provided with the fixing waist of guide rail 10
Type hole;The height of conveniently adjusted guide rail 10.Another side offers rubber plate 3 respectively and piston rod 4 is fixed
Waist-shaped hole, convenient regulation cylinder 9 fixed position, in order to reach to regulate the purpose of cylinder 9 stroke.
Embodiment
The course of work, when initial, cylinder 9 is in the state of tightening up, rubber plate 3 and plane weight on some sebific duct seat 7
Close.During work, 1 glue of workpiece points of proximity needle head, when once putting after glue completes, glue can overflow needle tubing.
Now, the piston rod of cylinder 9 stretches out, and is moved to by rubber plate 3 at the gum outlet of dispensing needle head 1, due to
Offer appearance glue chamber 13 on rubber plate 3, dispensing needle head 1 glue overflowed is enclosed into appearance by bowl structure
In glue chamber 13, and inhale needle head 2 and be arranged on appearance side, glue chamber 13, when rubber plate 3 is ejected by cylinder 9, inhale glue
Extraction valve opened by syringe needle 2, is absorbed by the glue of spilling in recovery capsule 8.Receive completely from being retracted at cylinder 9
During Jin, reclaim capsule 8 and be always maintained at the state of bleeding, and short stay, this completes a work
Circulate.
