Description

Technical Field

[0001] This utility model relates to an ergonomic dispensing auxiliary device, belonging to the field of auxiliary device technology. Background Technology

[0002] For electrical connector thread dispensing, apply adhesive evenly to three points along the connector threads. Depending on the connector size, each point typically contains approximately 0.04ml to 0.08ml of adhesive. The adhesive should form a spherical shape and not extend beyond the outer edge of the connector threads. Then, use a needle-like tool to spread the adhesive evenly, ensuring the adhesive does not exceed the width of the connector threads. If adhesive overflows from the outer edge of the threads, wipe it clean with a semi-dry cotton ball soaked in anhydrous ethanol.

[0003] Currently, the dispensing methods used are traditional manual dispensing or dispensing machine dispensing. Manual operation involves using a syringe to dispense glue. During dispensing, the index and middle fingers hold the syringe at the needle holder, and the thumb gently pushes on the piston. The amount of glue dispensed depends entirely on the force applied by the thumb, which easily leads to uneven dispensing and glue overflow. Once glue overflows, it needs to be cleaned and re-dispensed, increasing unnecessary workload and usually requiring a high level of manual skill. While dispensing machines can avoid these problems, they require a power and air supply, and the air intake and return parameters need to be adjusted to achieve precise dispensing. They also require a fixed workstation, making operation cumbersome and limiting their applicability.

[0004] Therefore, a simple and efficient dispensing aid is needed to solve these problems. Utility Model Content
