When the sensor probe is used, the sensor probe emits a detection signal, the detection signal can be reflected back to the probe when encountering the glue liquid level, and the detector outputs an analog signal according to the return signal or outputs a switching value signal according to a set value. The working principle is described by taking a reflective optical fiber as an example, an optical fiber head is arranged in an installation hole of an sensor probe, 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 an optical fiber amplifier outputs a switching value signal according to a return signal and a set value, so that whether the glue allowance reaches the set value is judged.

The dispensing device 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 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 set numerical value of the standby glue to be preheated 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 material cylinder at this time, the buzzer and the alarm indicator lamp are lightened to alarm. If the standby cylinder is filled with glue at this time, the dispensing head 40 corresponding to the working cylinder continues to dispense glue, the equipment which reaches the set glue emptying alarm value (the second threshold range) alarms and stops, the standby cylinder is replaced by the working cylinder, and after the working cylinder detects the change of the signal by detecting the optical fiber, the dispensing count is automatically cleared, and timing is restarted.
Example 2
Before the dispensing device 100 is used, the standby cylinder is at normal temperature, and standby glue is placed into the standby cylinder. When the number of processed products or the number of turns of the valve body of the dispensing valve 30 reaches the early warning, the standby cylinder begins to preheat and heat up, and if the early warning value (first preset value) is reached, no glue exists in the standby cylinder, and the red indicator lights are lighted to give an alarm. When the number of processed products reaches an alarm value (a second preset value), the equipment cannot operate, the buzzer and the alarm indicator lamp alarm, and the glue is waited for replacement. When the glue is replaced, the standby material cylinder stops heating and returns to the normal temperature state.
In summary, according to the dispensing device 100 and the dispensing method of the embodiment of the application, the control of the residual glue can be realized, the structure of the residual glue detecting equipment is simplified, and the production cost is reduced.
