Description

Technical Field

[0001] The utility model relates to the technical field of chip packaging, in particular to a chip packaging glue dispensing head. Background Art

[0002] The dispensing head is the output element of the dispensing machine, and most of them are cylindrical or tubular structures. During the dispensing process, the dispensing head is close to the surface of the workpiece, and the glue is input from one end of the dispensing head and output at the other end to form a bulge. As the output glue bulge increases, the glue adheres to the surface of the workpiece to form glue droplets. It is often used as a chip packaging equipment.

[0003] Some of the current dispensing equipment needs to work continuously. When the work is suspended, the glue will remain inside the dispensing head for too long and solidify, which will form a blockage inside the dispensing head, hindering the normal dispensing work. The entire dispensing head needs to be cleaned and unblocked, affecting work efficiency. If the dispensing head is not cleaned thoroughly and there is solidified glue residue inside, it will also affect the dispensing effect. Utility Model Content

[0007] The invention is further characterized in that: the base ring is provided with auger probe entrances in the upper and lower directions.

[0008] Furthermore, the mounting base includes a substrate, and mounting screws are fixedly mounted at the four corners of the substrate.

[0009] Furthermore, a card slot is provided on the front surface of the base, a card insert is slidably engaged in the card slot, a motor mounting seat is fixedly installed on the lower edge of the front surface of the card insert, and a locking bolt is inserted and installed on the upper edge of the front surface of the card insert.

[0012] Furthermore, the driving motor is fixedly mounted on the front side of the motor mounting seat, the discharging auger is inserted into the base ring and the inside of the main pipe, and the sealing turntable is sealed and rotatably connected to the auger insertion port through a sealing bearing.

[0013] Compared with the prior art, the beneficial effects of the present invention are:

[0014] 1. The overall structure is mounted on the mobile structure inside the dispensing equipment through the installation base, and the external injection pipe is connected through the injection interface. The dispensing work is carried out with the assistance of the discharging structure to push the discharging. The dispensing head body is designed to be an assembled structure.

This facilitates assembly. When a blockage occurs inside the dispensing head body, the various components can be disassembled from each other. The blockage location can be quickly checked and the blocked components can be quickly cleaned and dredged. The blocked components can also be directly disassembled and replaced, and then cleaned up later to avoid delaying the chip dispensing work.

[0015] 2. During dispensing, the sealing turntable and sealed bearings block the auger probe inlet, and the drive motor drives the discharging auger to rotate inside the main pipe. The auger blades push the glue liquid injected into the main pipe, so that the glue liquid is discharged from the glue injection needle.
