Precision, material, the outward appearance of needle head are very big to dispensing influential effect, particularly LED filament product, and quality for dispensing glue can direct shadow
Ring illuminating effect.Current LED filament generally uses circular hole dispensing needle head, circular hole dispensing needle head have high flow capacity, anti-clogging,
The point smoother uniform advantage of glue surface, but it can not be coated to substrate side surfaces, cause filament side to leak blue and hot spot not
Uniform defect.
The content of the invention
The utility model provides a kind of dispensing needle head of horseshoe clamp bottom opening of lamp holder provided with U-lag；Solve prior art
Middle presence can not wrap up the substrate side surfaces of filament and cause Lou it is blue, the problem of hot spot is uneven.
Above-mentioned technical problem of the present utility model is mainly what is be addressed by following technical proposals：A kind of horseshoe clamp bottom
The dispensing needle head of opening, including dispensing needle head body and the needle tubing which is provided with, it is characterised in that：The opening of the needle tubing bottom
Place is provided with the U-lag that Open Side Down, and the width of U-lag is less than the diameter of bore of needle tubing correspondence position, and U-lag is with needle tubing correspondence
The interior axially bored line of position is into being symmetrical set.During dispensing, the U-lag alignment on needle tubing head is needed into filament substrate axis for dispensing glue
Line, glue flows out via syringe intracavity from U-lag, and such glue can wrap up filament substrate side, it is to avoid cause filament base
The blue and uneven defect of hot spot is leaked in plate side, improves the illumination quality of filament.U-lag of the present utility model can be designed to not
The size of same specification is applied to different filament dispensings.
Preferably, the bottom of the U-lag is provided with horizontally disposed flat bottoms, and the width of flat bottoms is less than U-lag
Width.U-lag is provided with flat bottoms, for the positioning of filament, while it can make it that glue plastic emitting flowing is more uniform, protects
Card dispensing height during dispensing, while ensureing the uniformity of colloid shape, can improve dispensing quality with convenient controllable, it is ensured that
The uniformity of filament colour temperature and hot spot.
Preferably, the width of the U-lag is 1.5~3.5mm, the length of flat bottoms is 0.8~2mm.The width of U-lag
Spend for 1.5~3.5mm, the length of flat bottoms is 0.8~2mm, it is adaptable to which the filament of most of specifications, applicability is preferable.
Preferably, the height of the U-lag is 1.8~3mm.The glue thickness that the U-lag of so height is smeared compared with
To be appropriate.
Preferably, the endoporus of needle tubing is vertical bar shape and its axis is to be vertically arranged.The endoporus of needle tubing be vertical bar shape and its
Axis is is vertically arranged, and the glue flow velocity uniform, controllable for making it internal is conducive to improving encapsulated quality.
Preferably, the fore-and-aft direction width of the needle tubing endoporus is less than the width of its left and right directions, U-lag is along along needle tubing
The left and right directions distribution in hole is set.So the needle tubing endoporus gel quantity of shape conveniently, is conducive to improving encapsulated quality.
Therefore, the utility model has the characteristics that compared with prior art：1. the head of needle tubing offers U-lag, glue
Substrate side can be wrapped up, it is to avoid cause filament side to leak the blue and uneven defect of hot spot；The bottom of 2.U shape grooves is provided with flat
Straight flat bottoms, it is ensured that dispensing height can be with convenient controllable, while ensureing the uniformity of colloid shape during dispensing.

Embodiment
Below by embodiment, and with reference to accompanying drawing, the technical solution of the utility model is described in further detail.
Embodiment 1：See Fig. 1, Fig. 3, a kind of dispensing needle head of horseshoe clamp bottom opening, including dispensing needle head body 1 and set thereon
Provided with the U-lag 3 that Open Side Down at some needle tubings 2, the opening of the bottom of needle tubing 2, the width of U-lag 3 is less than the correspondence position of needle tubing 2
Diameter of bore, and U-lag 3 with the interior axially bored line of the correspondence position of needle tubing 2 into being symmetrical set.During dispensing, by needle tubing head
U-lag alignment need the axis of filament substrate 4 for dispensing glue, glue flows out via syringe intracavity from U-lag, and such glue can be with
By the side of filament substrate 4 parcel, it is to avoid cause the leakage of filament substrate side surfaces blue and the uneven defect of hot spot, improve the illumination of filament
Quality.U-lag of the present utility model can be designed to that the size of different size is applied to different filament dispensings.
See Fig. 4, the bottom of U-lag 3 is provided with horizontally disposed flat bottoms 31, and the width of flat bottoms 31 is less than U-lag 3
