In the prior dispensing amount control technology, the total dispensing amount is finally controlled by controlling the switching time of the dispensing valve 4;
in the glue dispensing device, a glue amount control device is added, wherein a needle cylinder device, an upper sensor 7 and a lower sensor 6 are arranged; the upper inductor 7 and the lower inductor 6 are respectively arranged on the vertical needle cylinder 3 of the needle cylinder device and are used for inducing the colloid with the same horizontal height;
by the main control device, the needle cylinder 3 is filled with glue, namely the glue filling valve 2 is controlled to be opened until the upper sensor 7 senses the glue in the needle cylinder 3, so that the height of the glue in the needle cylinder 3 reaches the height corresponding to the upper sensor 7; dispensing is carried out, namely the dispensing valve 4 is controlled to be opened until the lower sensor 6 cannot sense that the colloid exists in the needle cylinder 3, so that the colloid is discharged until the height of the colloid in the needle cylinder 3 reaches the height corresponding to the lower sensor 6;
therefore, the glue amount corresponding to the height between the upper inductor 7 and the lower inductor 6 is the glue dispensing amount discharged from the glue outlet 9B; because the positions of the upper inductor 7 and the lower inductor 6 are relatively fixed, the volume of the glue dispensing amount is fixed and unchanged, and the quality of the glue dispensing amount is also fixed; therefore, the glue dispensing amount can be automatically and accurately controlled, excessive labor cost is avoided, waste of the glue amount can be avoided, and therefore production cost is reduced and production efficiency is improved.
Further, the syringe device also comprises a dispensing piston 5 which is arranged at the top end of the syringe 3; the novel glue dispensing device also comprises an air pressure device which is connected with the glue dispensing piston 5 and used for pushing the glue dispensing piston 5 to push the glue downwards in the needle cylinder 3.

and B: and controlling the dispensing valve 4 to open for dispensing until the lower inductor 6 does not induce the colloid.
In actual operation, glue is filled first and then dispensed.
The glue dispensing amount corresponding to the height between the upper inductor 7 and the lower inductor 6 is the glue dispensing amount discharged from the glue outlet 9B; because the positions of the upper inductor 7 and the lower inductor 6 are relatively fixed, the volume of the glue dispensing amount is fixed and unchanged, and the quality of the glue dispensing amount is also fixed; therefore, the glue dispensing amount can be automatically and accurately controlled, excessive labor cost is avoided, waste of the glue amount can be avoided, and therefore production cost is reduced and production efficiency is improved.
Further, step B specifically includes:
step B1: meanwhile, the dispensing valve 4 and the air pressure device are controlled to be opened, so that the air pushes the dispensing piston 5 to push the glue downwards in the needle cylinder 3 and the glue is discharged through the glue outlet 9B;

before the dispensing operation, the dispensing operation is performed. When the upper sensor 7 does not sense the glue, the program drives the pneumatic valve 2 to open, the glue enters the filter 1 through the glue inlet 9A and is filled into the needle cylinder 3 through the connecting rubber tube; when the upper sensor 7 can sense that the glue in the needle cylinder 3 is filled, the program drives the pneumatic valve 2 to close, and the glue filling is finished.
When the dispensing action is executed, the program drives the dispensing valve 4 to open, and simultaneously adds nitrogen to the nitrogen pressurizing port 9C for pressurizing, and the high-pressure nitrogen pushes the dispensing piston 5 to push the glue downwards so as to discharge the glue through the dispensing outlet; when the glue drops to the lower inductor 6 and cannot be induced, the program drives the glue dispensing valve 4 to close and simultaneously cuts off the nitrogen of the glue dispensing piston 5, and the glue dispensing is finished.
