Abstract
The utility model relates to a dispensing needle used for dispensing protective glue on pipe cores of elements arranged on pipe seats and internal leads thereof, and the needle is a hollow pipe. The dispensing needle is characterized in that a notch is formed on the pipe wall of the tip of the needle. Because a notch is formed on the pipe wall of the tip of the needle, dispensed protective glue can be widely and smoothly covered on pipe cores of elements, and the pipe cores can be totally covered with glue.
Description
Technical field
The utility model relates to a kind of dispensing needle head, relates in particular to the tube core that is installed on the components and parts on the base and the dispensing needle head of lead point protection glue thereof.
Background technology
In the prior art, general dispensing needle head is a hollow tube with common tack dispensing needle head to the tube core point protection glue of SAW device, and pipe end and the body of putting sebific duct are similarly whole hollow pipe shape.Narrower with the protection glue that this some sebific duct point comes out to the overlay area of tube core, and the thickness out-of-flatness, the problem that glue does not cover tube core fully can be produced.As shown in Figure 1 and Figure 2, the glue area of coverage 2 that point comes out on the tube core of SAW device 1 is narrower.
The utility model content
The applicant has carried out research the glue broad and the smooth dispensing needle head of thickness that provide a kind of point to come out has been provided at the narrower and irregular problem of thickness of the protection glue area of coverage that above-mentioned dispensing needle head point comes out.
In order to solve the problems of the technologies described above, the utility model adopts following technical scheme:
A kind of dispensing needle head, syringe needle are hollow tube, have notch on the tube wall of described syringe needle end.
The plane of symmetry of above-mentioned notch is by the central axis of syringe needle hollow tube
Above-mentioned notch is rectangular or semicircle.
Technique effect of the present utility model is:
Owing to have notch on the tube wall of syringe needle end, glue area of coverage broad and thickness that point comes out are smooth, and protection glue can cover tube core fully.
Description of drawings
Fig. 1 is with the effect schematic diagram behind the tack dispensing needle head point glue of prior art.
Fig. 2 is the left view of Fig. 1.
Fig. 3 is a structural representation of the present utility model.
Fig. 4 is the upward view of Fig. 3.
Fig. 5 is with the effect schematic diagram behind the utility model point glue.
Fig. 6 is the left view of Fig. 5.
The specific embodiment
Below in conjunction with accompanying drawing the specific embodiment of the present utility model is described in further detail.
As shown in Figure 3, Figure 4, syringe needle 3 is a hollow tube, has notch 4 on the tube wall of syringe needle 3 ends, the plane of symmetry of notch 4 is by the central axis of syringe needle hollow tube, notch 4 can be rectangle, semicircle or other symmetric shape, and in the present embodiment, notch 4 is a rectangle.Can see that by Fig. 5, Fig. 6 the utility model point comes out on the tube core of SAW device 5 protection glue 6 area of coverage broads and thickness is smooth, among Fig. 5, Fig. 6, the tube core and the lead thereof of components and parts be arranged below the protection glue 6.Among Fig. 1 and Fig. 5, do not encapsulate pipe cap as yet on SAW device 1 and the SAW device 5.
Claims (3)
