Description

Technical Field

[0001] The utility model belongs to the technical field of precision instrument manufacturing, and particularly relates to an infrared lens pneumatic glue dispensing device. Background Art

The servo glue pushing mechanism includes a glue pushing motor, a linear screw guide device, a glue pushing rod, a glue dispensing syringe, and a glue dispenser. The glue pushing motor, the linear screw guide device, the glue pushing rod, the glue dispensing syringe, and the glue dispensing device are provided. The linear screw guide device, the glue pushing rod and the glue dispensing syringe are installed on the bracket of the Z1 axis. The linear screw guide device is installed under the glue pushing motor and is connected to the glue pushing motor; the top of the glue pushing rod is connected to the bottom of the linear screw guide device, the bottom of the glue pushing rod is set in the glue dispensing syringe, the glue dispenser is installed on the annular track motion mechanism and is connected to the glue dispensing syringe through a hose; the glue dispensing syringe is filled with glue, the glue pushing motor drives the linear screw guide device to move, the linear screw guide device drives the glue pushing rod to move vertically, squeezes the glue in the glue dispensing syringe, and the other glue enters the glue dispensing syringe along the hose, and then the glue dispensing work is completed through the glue dispensing syringe.

[0003] However, the servo glue push mechanism in the invention is driven by a servo motor to push the glue push rod. The glue needs to be transported through a very long hose before it can reach the glue dispensing syringe and can be dispensed. If the glue remaining in the hose is not cleaned in time, it is easy to clog the hose, and a large amount of glue remains in the hose, causing waste. Secondly, the glue dispensing syringe is installed in the glue dispenser, which is driven by two gears to adjust the angle. However, when using it, it can only roughly estimate the angle adjustment degree, and it is difficult to deal with situations where the angle degree needs to be accurately adjusted.
