Description

Technical Field

[0001] This utility model relates to the field of dispensing machine accessories, specifically to a novel dispensing needle structure. Background Technology

[0002] In some communication equipment, glue is usually applied to the connection face using a dispensing machine. The existing dispensing machines are equipped with dispensing needles that dispense glue through round or triangular holes. The round dispensing needles cannot meet the height requirements of the glue, while the triangular dispensing needles have an unstable width. When magnified, the glue appears wavy on both sides and in the height direction, which cannot meet the customer's requirements for the appearance of the glue. Therefore, it is necessary to redesign the structure of the dispensing needle. Summary of the Invention

[0003] To address the shortcomings of the existing technology, this utility model provides a novel dispensing needle structure that improves the shape of the dispensing nozzle and enhances dispensing stability.

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0005] A novel dispensing needle structure is characterized by comprising a connecting seat and a needle tube connected in sequence, wherein the end of the needle tube has a dispensing part, the dispensing part is a flat tube structure, one end of the dispensing part in the length direction has a dispensing bevel, and the other end of the dispensing part in the length direction has a back bevel.

[0006] Furthermore, the vertical height of the glue dispensing bevel is 1.05-1.29 mm, the width is 0.79-0.93 mm, and the apex of the glue dispensing bevel is offset by 0.2-0.4 mm from the center point of the needle tube towards the side of the bevel.

[0007] Furthermore, the vertical height of the back slope opening is lower than the vertical height of the glue dispensing slope opening.

[0008] Furthermore, both the connector and the needle are made of stainless steel.

[0009] The beneficial effects of this utility model include: the dispensing needle has a simple structure, low manufacturing cost, can effectively improve the dispensing effect, stable colloid molding dimensions, and high appearance quality. Attached Figure Description

[0012] Figure 3 This is a front view of the glue dispensing angled opening of this utility model. Detailed Implementation

[0013] The present invention will be further described in detail below with reference to specific embodiments and accompanying drawings.

[0014] One such Figure 1-3 The novel dispensing needle structure shown includes a connecting seat 1 and a needle tube 2 connected in sequence. Both the connecting seat 1 and the needle tube 2 are made of stainless steel. The end of the needle tube 2 has a dispensing part 3, which is a flat tube structure formed by uniformly pressing the needle tube 2. One end of the dispensing part 3 along its length is ground to form a dispensing bevel 4, and the other end is ground to form a back bevel 5.

[0015] Based on the size requirements of the colloid after curing after dispensing, the vertical height of the dispensing bevel 4 in this embodiment is 1.05-1.29 mm, the width is 0.79-0.93 mm, and the apex of the dispensing bevel 4 is offset by 0.2-0.4 mm from the center point of the needle tube towards the bevel 5. This structure can meet the requirements of large-sized colloids to achieve one-time molding.

[0016] To ensure a good connection between the starting and ending positions of the glue application, the vertical height of the back bevel 5 in this embodiment is lower than the vertical height of the glue outlet bevel 4.

[0017] The dispensing machine of this invention, after multiple tests following program debugging, showed that the dispensing material not only met the height and size requirements, but also exhibited a stable, uniform shape and good continuity.

[0018] The technical solutions provided by the embodiments of this utility model have been described in detail above. Specific examples have been used to illustrate the principles and implementation methods of the embodiments of this utility model. The description of the above embodiments is only for helping to understand the principles of the embodiments of this utility model. At the same time, for those skilled in the art, there will be changes in the specific implementation methods and application scope based on the embodiments of this utility model. Therefore, the content of this specification should not be construed as a limitation of this utility model.
