Aiming at the problems that in the traditional dispensing equipment, at the initial stage of dispensing operation, more adhesive is in a glue barrel, the glue outlet amount of a needle-shaped dispensing tube is larger under the dual action of air and the gravity of the adhesive, and at the later stage of dispensing operation, less adhesive is in the glue barrel, and under the same air pressure, the glue outlet amount of the needle-shaped dispensing tube is smaller, so that the glue is not uniformly coated, the newly designed dispensing equipment is shown in figures 1 and 2. As shown in the figure, the dispensing apparatus 10 mainly includes a gas output device 11, a glue barrel 12 and a controller 23; the gas output device 11 comprises an air inlet pipeline 14 and an air feeding pipeline 27, wherein the air inlet pipeline 14 is communicated with an external gas source 13, and the air feeding pipeline 27 is communicated with the glue barrel 12. The air feed line 27 feeds compressed air into the glue bucket 12, the glue bucket 12 being used to contain the adhesive and being provided with the push rod 16.

The dispensing apparatus 10 is further provided with a detection assembly 17 and a controller 23, wherein the detection assembly 17 is configured to detect the position of the push rod 16 in the glue barrel 12, and generate and output a position detection signal. The controller 23 is communicatively connected to the detection assembly 17, i.e. data transmission may be performed by means of a wired connection or a wireless connection. The controller 23 receives the position detection signal, generates and outputs a driving signal to the gas output device 11 to adjust the gas pressure in the gas supply line 27 so that the change in the gas pressure of the compressed air supplied into the glue bucket 12 from the gas supply line 27 is adapted to the position of the push rod 16, i.e., the amount of adhesive stored in the glue bucket 12, ensuring that the problem of uneven gluing does not occur.
As an alternative, a magnetic element 20 is arranged in the plunger 16. The detecting assembly 17 includes a plurality of hall sensors disposed at one side of the glue barrel 12, and the hall sensors are configured to detect the magnetic element 20, that is, detect the position of the push rod 16, and generate and output a position detection signal. As an example, only one hall sensor may be provided and installed in the middle of the glue barrel 12, when the compressed gas pushes the push rod 16 to move to the middle of the glue barrel 12, the magnetic element 20 in the push rod 16 approaches the hall sensor, and the output end of the hall sensor outputs an active level signal (e.g., a low level signal), that is, a position detection signal, to the controller 23.
