In some embodiments of the present application, the dispensing valve 30 is a screw valve. When the dispensing valve 30 is a screw valve, the remaining amount of glue in the working cylinder can be calculated by the number of rotations of the rotating shaft of the screw valve. The number of revolutions of the rotary shaft of the screw valve can be calculated by sensing the MARK point of the rotary shaft of the fiber-optic induction screw valve.
According to an embodiment of the present application, the dispensing apparatus 100 further includes a display, and the display is connected to the counter for displaying the quantity information obtained by the counter. For example, the number of rotations of the rotating shaft of the screw valve and the number of times of glue replacement can be displayed in real time through the display, so that the time for replacing the working material cylinder can be judged in advance.

During assembly, the sensor probe of the first fiber optic sensor 50 may be installed into the sensor probe mounting hole, the vent tube 90 may be installed to the vent tube interface 91, and finally the assembled adapter may be installed onto the first cartridge 21. When the device is used, the sensor probe emits a detection signal, the detection signal can be reflected back to the probe when meeting the glue liquid level, and the detector outputs an analog quantity signal according to the return signal or outputs a switching value signal according to a set value. The working principle is explained by taking a reflection-type optical fiber as an example, the optical fiber head is arranged in the sensor probe mounting hole, the optical fiber head emits an infrared signal, the infrared signal is reflected back to the optical fiber head when encountering the glue liquid level, and the optical fiber amplifier outputs a switching value signal according to the return signal and a set value, so that whether the glue residual reaches the set value is judged.

The dispensing apparatus 100 according to the embodiment of the present application will be described with reference to the following embodiments.
Example 1
In the dispensing production process, the rotating number of turns of the rotating shaft of the valve body of the screw valve is displayed in real time through the display, and when the preset numerical value of needing to preheat the standby glue is reached, the temperature controller 70 controls the heating element 60 to heat the glue in the standby material cylinder. If no glue exists in the standby charging barrel at the moment, the buzzer and the alarm indicator light are turned on to give an alarm. If glue is loaded in the spare material cylinder at the moment, the glue dispensing head 40 corresponding to the working material cylinder continues glue dispensing production, the device alarms and stops when the preset glue emptying alarm value (within the range of a second threshold value) is reached, the spare material cylinder is replaced by the working material cylinder, the glue dispensing counting is automatically reset after the working material cylinder detects the signal change, and timing is restarted.
Example 2
Before the dispensing device 100 is used, the standby material cylinder is in a normal temperature state, and standby glue is put into the standby material cylinder. After the number of the processed products or the number of valve body rotation turns of the dispensing valve 30 reaches the early warning, the standby material cylinder starts to be preheated and heated, and if the standby material cylinder reaches the early warning value (the first preset value), no glue exists in the standby material cylinder, and the red indicator lamp is turned on to give an alarm. When the number of the processed products reaches an alarm value (a second preset value), the equipment cannot run, and the buzzer and the alarm indicator lamp give an alarm to wait for replacing the glue. When the glue is replaced, the standby charging barrel stops heating, and the normal temperature state is recovered.
In summary, according to the dispensing device 100 and the dispensing method of the embodiment of the present application, the control of the glue residual amount can be realized, the structure of the glue residual amount detection device is simplified, and the production cost is reduced.
