The embodiments described below with reference to the drawings are exemplary and intended to be used for explaining the present invention, and should not be construed as limiting the present invention.

In the description of the present invention, unless expressly stated or limited otherwise, the terms "connected," "connected," and "fixed" are to be construed broadly, e.g., as meaning permanently connected, detachably connected, or integral to one another; can be mechanically or electrically connected; either directly or indirectly through intervening media, either internally or in any other relationship. The specific meaning of the above terms in the present invention can be understood in specific cases to those skilled in the art.

In the present disclosure, unless expressly stated or limited otherwise, the first feature "on" or "under" the second feature may comprise direct contact between the first and second features, or may comprise contact between the first and second features not directly. Also, the first feature "on," "above" and "over" the second feature may include the first feature being directly above and obliquely above the second feature, or simply indicating that the first feature is at a higher level than the second feature. A first feature being "under," "below," and "beneath" a second feature includes the first feature being directly under and obliquely below the second feature, or simply meaning that the first feature is at a lesser elevation than the second feature.

As shown in fig. 1-4, a small-pitch dispensing structure 10 according to the present application includes: a plurality of syringe needles 11 and mounting panel 13, syringe needle 11 are used for aiming at some glue positions and carry out some glue, thereby mounting panel 13 is used for installing a plurality of syringe needles 11 and drives syringe needle 11 under the drive of the drive structure of device and move some glue. The mounting plate 13 is formed with a plurality of mounting holes 131, and these mounting holes 131 are arranged along a straight line, and a plurality of needles 11 are respectively inserted in a plurality of mounting holes 131. The needle 11 is formed with an insertion portion 111, and the insertion portion 111 is inserted into the mounting hole 131, thereby mounting the needle 11. A dispensing portion 114 is formed below the insertion portion 111, and the dispensing portion 114 is used for dispensing while aligning a dispensing position. The inserting portion 111 is formed with and stores up gluey passageway in order to be used for storing glue, and some glue portion 114 is formed with some gluey passageway in order to be used for some gluey, and the lower extreme demountable installation of some glue portion 114 has the some glue mouth 12 that is formed with out gluey hole, and the both ends of some glue passageway communicate respectively and store up gluey passageway and play gluey hole, can clean syringe needle 11 through dismantling some glue mouth 12 to guarantee some gluey smoothness nature.

The dispensing nozzle can be detachably arranged at the lower end of the dispensing part in an inserting manner.

Further, the dispensing part 114 is a cone formed with a large end 115 and a small end 116, the diameter of the end of the large end 115 is 1mm from the diameter of the insertion part 111, the diameter of the end of the small end 116 is 0.48mm, the length of the insertion part 111 is 8.6mm, the length of the dispensing part 114 is 4.4mm, the diameter of the glue storage channel is 0.7mm and the length is 8mm, and the diameter of the dispensing channel is 3mm and the length is 3.4mm. Such size and structure setting make the shared space of syringe needle 11 less to can realize reducing the installation distance between two syringe needles 11, and then can glue the product that the distance requirement is less to the point and glue, and because syringe needle 11 is more slender, the contact position is less, makes the point glue more accurate.

In a specific embodiment, the insertion portion 111 is formed with a stopper boss 113. The limiting boss 113 is used for abutting against the bottom side of the mounting plate 13 to prevent the needle 11 from moving axially in the mounting hole 131, so as to ensure the accuracy of the dispensing operation. Here, the outer diameter of the limit projection 113 is 1.8mm, which can reduce the interval between the two needles 11.
