Description
Technical Field
The utility model relates to an electronic circuit board processing technology field especially relates to a dispensing nozzle.
Background
In the field of electronic circuit board processing, in order to keep working stability and service life, glue is often used for bonding, a nozzle is used for spraying a circuit board, and various electronic components are bonded. The nozzle part is the main part of the dispenser and directly influences the glue discharging quality. The existing spray head is composed of a stainless steel spray nozzle, the spray nozzle is installed at the front end of a shell, a firing pin is arranged in the middle of the shell, and glue is sprayed out through the firing pin.
The published Chinese utility model patent has the publication number: CN207899612U, patent name: dispensing nozzle and point gluey pump, application date: 20180124, which discloses a glue dispensing nozzle and a glue dispensing pump using the same, the glue dispensing nozzle is arranged at the working end of the glue dispensing pump and is matched with a firing pin in the glue dispensing pump to realize the injection of filling glue; the glue dispensing nozzle comprises a nozzle body and a glue spraying hole penetrating through the nozzle body; the extension direction of the glue spraying hole is not coincident with the reciprocating direction of the firing pin. When the adhesive dispensing operation is carried out, the filling adhesive is sprayed out from the adhesive spraying hole of the adhesive dispensing nozzle at an inclined angle, can be simultaneously combined with the substrate to be bonded and the chip, and flows to a gap between the chip and the substrate by the surface tension of the filling adhesive. Compare with traditional point and glue the nozzle, the utility model provides a point is glued the nozzle and is sprayed the packing with the slope mode and glue, can adapt to better and let the dead zone size reduce, avoid the packing to glue contaminated element or pad, need not simultaneously to set up the hole that will spout gluey hole less, has also avoided the problem that the nozzle needs frequent change to glue.
At present, due to the rapid development of the electronic industry, various complex electronic circuit boards require high-precision machinery and accessories, so that the common nozzle cannot meet the requirements, and ceramics have excellent performances which many metals do not have.
SUMMERY OF THE UTILITY MODEL
The utility model relates to a glue dispensing nozzle, the whole ceramic material that is made of nozzle possesses the not good performance that metal nozzle did not possess.
The utility model provides a dispensing nozzle which is arranged at the working end of a dispensing pump and is matched with a firing pin in the dispensing pump to realize the injection of filling glue;
the dispensing nozzle comprises a nozzle body 1, a firing pin hole 3 penetrating through the nozzle body 1, and a firing pin 2 arranged in the firing pin hole 3;
the nozzle body 1 is arranged in a table shape; the nozzle body 1 is made of ceramic.
Preferably, the nozzle body 1 is arranged in a circular truncated cone shape.
The utility model has the advantages that: simple structure, reasonable in design, the every minute of spraying can be more than 200, the uniformity is good, and operating pressure can reach 90 PSI. The glue dots have good shape and the size of the glue dots is 0.03 nl.
Drawings
FIG. 1 is a schematic structural view of the present invention;
FIG. 2 is a front view of the present invention;
in the figure, the position of the upper end of the main shaft,
1. a nozzle body; 2. a striker; 3. and (4) punching the pin hole.
Detailed Description
The present invention will now be described in detail with reference to the drawings, which are provided for illustrative and explanatory purposes only and should not be construed as limiting the scope of the present invention in any way.
The utility model provides a dispensing nozzle which is arranged at the working end of a dispensing pump and is matched with a firing pin in the dispensing pump to realize the injection of filling glue;
the dispensing nozzle comprises a nozzle body 1, a firing pin hole 3 penetrating through the nozzle body 1, and a firing pin 2 arranged in the firing pin hole 3;
the nozzle body 1 is arranged in a table shape; the nozzle body 1 is made of ceramic.
In this embodiment, preferably, the nozzle body 1 is disposed in a circular truncated cone shape.
The nozzle body 1 is installed at the front end of the dispensing pump, the middle part of the nozzle body 1 is provided with a firing pin 2, and the glue is ejected by the striking pin 2. The nozzle can work for 24 hours, has long service life, does not need to be frequently replaced and cleaned, greatly improves the working efficiency, and has reliable quality because the whole nozzle is made of ceramic materials.
It should be noted that the terms "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inner", "outer", etc. indicate orientations or positional relationships based on the orientations or positional relationships shown in the drawings, and are only for convenience of describing the present invention and simplifying the description, but do not indicate or imply that the device or element referred to must have a specific orientation, be constructed in a specific orientation, and be operated, and thus should not be construed as limiting the present invention. Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and are not to be construed as indicating or implying relative importance.
