Abstract
The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Please refer to fig. 1, the present invention provides a technical solution: a sharp needle comprises a needle seat 2, wherein the upper end of the needle seat 2 is provided with a Ruhr joint 1, the lower end of the needle seat 2 is provided with a needle head 3, and the lower end of the needle head 3 is designed with sharp processing 4. The working principle is as follows: when the glue dispensing device is used, when glue is dispensed through the needle head, the glue is connected with the needle cylinder through the Ruhr connector, the glue in the needle cylinder enters the sharp processing part after passing through the needle heads with different inner diameters (the inner diameters can be customized), and then the sharp processing part is contacted with a component, so that precise glue dispensing is realized.
Description
(I) technical field
The invention relates to a sharp needle head which is mainly suitable for the electronic industry, the lighting industry, the automobile industry, the industrial electrical industry and the like.
(II) background of the invention
The traditional dispensing needle head is flat, the size of the dispensing point is based on the inner diameter of the needle head, for example, the inner diameter is 0.1mm, the outer diameter is 0.23mm, the dispensing point with the diameter of more than 0.23mm can be realized, more precise dispensing can not be finished, and liquid substances can be hung on the needle head. Therefore, we propose a sharp needle.
(III) contents of utility model
The invention overcomes the defects of the prior art, provides the sharp needle head, leads the operation of workers to be more convenient, saves the operation time and has smaller glue spots.
In order to achieve the above purpose, the present invention provides the following solutions: the utility model provides a sharp syringe needle, includes luer joint, needle file, syringe needle, sharp processing, luer joint is fixed in needle file upper end, the syringe needle is at the needle file lower extreme, and the syringe needle is connected with the needle file, sharp processing is at the syringe needle bottom, and the syringe needle is connected with sharp processing, luer joint, needle file, syringe needle and sharp processing homogeneous body shaping.
Preferably: the luer connector is designed with double threads, so that the needle cylinder can be firmly installed.
Preferably: the needle seat is made of polypropylene.
Preferably: the bottom of the needle head is sharp and tapered.
Preferably: the minimum inner diameter of the needle head is 0.1mm, and the maximum inner diameter of the needle head is 0.84mm
Compared with the prior art, the beneficial effects of the utility model are that: this sharp syringe needle through syringe needle bottom sharp processing, prevents that the liquid material from climbing the needle point, has realized the stability of coating volume, utilizes the pointed high accuracy toper shape of needle point, can carry out a little point and glue, utilizes the firm installation cylinder of double thread design.
(IV) description of the drawings
Fig. 1 is a schematic structural diagram of the present invention.
In the figure: 1. a luer fitting; 2. a needle seat; 3. a needle head; 4. and (4) performing sharp processing.
(V) detailed description of the preferred embodiments
In order to make the objects, technical solutions and advantages of the present invention more apparent, the present invention will be described in further detail with reference to the accompanying drawings and embodiments.
Referring to fig. 1, the invention provides a sharp needle which mainly comprises a luer connector, a needle seat, a needle and a sharp processing.
The luer connector is fixed at the upper end of the needle seat and is used for firmly installing the sharp needle head on the needle cylinder.
The sharp processing is carried out on the needle tip part of the needle head, so that the needle tip part is in a high-precision conical shape, liquid substances are prevented from climbing up the needle tip, and trace dispensing is realized. For example, the inner diameter of a traditional needle head is 0.1mm, the outer diameter of the traditional needle head is 0.23mm, the outer diameter of the needle tip part can be 0.18mm through sharp processing, glue dots within 0.2mm can be realized, and then more precise glue dispensing is realized.
Claims (3)
1. A sharp needle is characterized by comprising a Ruhr joint (1), a needle seat (2), a needle head (3) and sharp processing (4).
2. A sharp needle according to claim 1, wherein the upper end of said needle holder (2) is a large end, and a luer (1) is provided at the large end, enabling a needle cylinder to be firmly mounted.
3. A sharp needle according to claim 1, wherein said sharp edge (4) is tapered to prevent liquid material from climbing up the needle tip and thereby achieving micro dispensing.
