[0032] Working principle:

[0033] The upper shell 1 and lower shell 2 are fixedly connected to form a stable main structure, providing solid support for the internal components. The extension handle 6 is movably connected to the inner wall of the upper shell 1 via a pressure spring 7, and is limited by partitions 19 on both sides to ensure stability under external force. The snap-fit ​​nozzle 4, as a key component for glue delivery, is fixedly connected to the lower shell 2 and the nozzle 3 to ensure a smooth glue delivery path and prevent accuracy loss due to shaking.

[0034] The upper slider 8 and the lower slider 17 achieve regular reciprocating motion in the vertical direction through the cooperation of the threaded post 15 and the threaded hole 18. This design is driven by the drive motor 9. By controlling the forward and reverse rotation of the motor, the threaded post 15 moves up and down in the threaded hole 18, thereby adjusting the distance between the nozzle 3 and the surface to be glued, ensuring the accuracy and uniformity of glue dispensing.

[0035] The vertical reciprocating motion of the threaded column 15 not only enhances the stability of the dispensing process, but also allows for flexible adjustment in different working environments to meet different process requirements.

[0036] The nozzle 3 is equipped with a heating device 11 at the lower end and a heating ring 12 at the upper end. It is connected to an external power supply through a circuit interface 13 to achieve rapid heating of the adhesive. The heating device 11 and the heating ring 12 work together to effectively improve the fluidity of the adhesive in low-temperature environments, ensuring that the adhesive maintains suitable viscosity and fluidity during transfer and dispensing.

[0037] The adhesive enters through the feed port 14 at the upper end of the snap-fit ​​nozzle 4, passes through the snap-fit ​​nozzle 4 and the spray nozzle 3, and is finally applied to the target location at a stable flow rate and in a uniform amount under the control of the drive motor 9. Throughout the process, the smooth delivery of adhesive and the stability of dispensing are ensured by the precise cooperation and reasonable design of each component.

[0038] In summary, the dispensing needle of this invention, through optimized structural design and the use of a combination of drive adjustment and heating temperature control, achieves stability in glue transfer and precision in dispensing, thereby improving production efficiency and product quality. It has significant technological advancements and practical value.
