Description

Anti-drop glue dispensing needle for die bonder Technical Field The utility model relates to the technical field of die bonders, in particular to a glue dropping preventing dispensing needle for a die bonder. Background The LED lamp beads may include a bracket, a light emitting die, a lead frame, and other components, wherein the fixed mounting of the light emitting die needs to be completed by a die bonder, and before the die transfer, a dispensing head of the die bonder is generally required to dispense the mounting portion of the lead frame. However, the conventional dispensing head is generally the same as the dispensing head of a novel mini LED die bonder with the patent grant publication number CN 219745334U, the dispensing position of the dispensing head is in a plane step, and the dispensing head is easy to throw off the glue in the high-speed swing operation after the dispensing head takes the glue. Disclosure of utility model The utility model aims to overcome the defects in the prior art and provides the glue dispensing needle for the die bonder, which adopts the design of the glue dropping prevention groove and can prevent glue dropping. In order to achieve the above purpose, the utility model provides a glue dispensing needle for a glue dropping prevention die bonder, which comprises a glue dispensing needle body, wherein an end plane is arranged at the bottom of the glue dispensing needle body, a glue head which is longitudinally arranged and is cylindrical is connected to the middle of the end plane, the diameter of the glue head is smaller than that of the glue dispensing needle body, a glue dropping prevention groove which is upwards concave is arranged on the end plane, the glue dropping prevention groove is arranged in a circular shape, and the glue dropping prevention groove is arranged around the glue head. Preferably, the upper end of the dispensing needle body is cylindrical, and the lower end of the dispensing needle body is conical. Preferably, the depth of the anti-falling glue groove is 0.1 mm-0.3 mm. Preferably, the outer wall of the upper end of the dispensing needle body is provided with at least one convex ring for preventing glue from creeping. Preferably, two convex rings are arranged at intervals from top to bottom. Preferably, the dispensing needle body and the adhesive head are both made of tungsten steel materials. Compared with the prior art, the utility model has the beneficial effects that: The utility model has simple structure and reasonable design, and the glue dropping prevention groove which is arranged around the glue head is arranged on the end plane of the glue dispensing needle body, so that the problem that the glue is easy to drop in the high-speed swinging working process after the glue is taken by the glue dispensing head can be solved.
