When the central controller gives out a dispensing signal, the filling unit 2 is kept in a closed state, the control box 4 sends a command to the second electromagnetic valve to enable the piston of the second spring cylinder 33 to move backwards, and a colloid channel in the rubber outlet pipe 39 is opened; meanwhile, the control box 4 sends a command to the servo motor to enable the output shaft of the servo motor to rotate forward, so that the piston rod 153 is driven to move forward, glue in the glue storage cavity 16 is extruded into the glue gun 3 through the connecting block 5 and flows out from the glue outlet B3 of the glue gun, and glue dispensing or gluing operation is carried out, as shown in fig. 7. When the central controller gives out a stop glue operation signal or the position sensor 14 indicates that the glue amount is insufficient, the control box sends an instruction to the second electromagnetic valve to enable the piston of the second spring cylinder 33 to move forwards, a glue channel in the glue outlet pipe 39 is closed, and the glue gun 3 stops glue outlet; at the same time, the control box 4 will instruct the glue storage unit 1, the filling unit 2 to perform a glue filling action.
The user can set the glue coating or glue dispensing operation glue pressure through the control system, the pressure sensor 51 detects the glue pressure in real time, when the glue pressure is too low or too high, the control box feeds back the signal to the central controller, stops the glue coating or glue coating action, closes the glue outlet B3 of the glue gun, controls the filling unit 2 to implement the glue filling action or controls the glue storage unit 1 to move, and adjusts the glue pressure.
Because the planetary roller screw has high motion precision and quick motion response, and can not shake and creep, the flow and the pressure of the colloid can be precisely controlled by controlling the motion speed of the planetary roller screw, and a spring cylinder is adopted as a glue discharging and closing motion executing mechanism, so that the planetary roller screw has quick motion response and plays a role in precise quantification.
