Working principle of automatic dispensing machine:

The working principle of the automatic dispensing machine is as follows. The compressed air is fed into the rubber bottle (syringe), and the rubber is pressed into the feeding pipe connected with the piston chamber. When the piston is on stroke, the piston chamber is filled with rubber. When the piston pushes down the rubber needle, the rubber is pressed out of the needle nozzle. The amount of glue dropping is determined by the distance of the piston dropping. It can be adjusted manually or controlled by software. Features: Fast speed, low sensitivity to the viscosity of adhesives. 

The working principle of dropping pump dispensing machine: the compressed air is fed into the rubber bottle (syringe), the glue is pressed into the feeding pipe, and the glue flows through the screw which rotates at a fixed time and a specific speed. The rotation of screw forms shear force on glue, which makes glue flow downward along the thread. The rotation of screw continuously pressurizes glue, which makes glue flow out of the needle nozzle of dropping glue. Flexibility and no fixed restriction on the diameter of glue point can be adjusted by software. However, the working principle of automatic dispensing machine should be followed and large glue points should be dropped at the moment. When the screw rotates for a long time, the output of the whole machine will be reduced. In addition, the viscosity and flow characteristics of adhesives will affect their stability.

The working principle of the automatic dispensing machine is applicable to most equipment. The working principle of the non-contact dispensing machine is that the compressed air is fed into the rubber bottle (syringe), the glue is pressed into the feeding tube connected with the piston chamber, heated in the feeding tube, and the temperature is controlled to achieve the best uniform viscosity. Using the socket structure, the glue fills the gap left by the ball retracting from the socket. When the ball comes back, due to the force of acceleration, the glue flow is cut off, which makes the ball eject from the nozzle of the dropping needle and drip onto the board to form the glue dot characteristics: eliminating the traditional method of glue dot tailing; there is no wear of the dropping needle and interference with other parts; no damage of the needle nozzle; due to the bending of the substrate and the damage of the needle nozzle. Bad, no debris
