[0042] As shown in the Figures 1-3 The present embodiment provides a dispensing device 100, which is mainly used for dispensing a product to be dispensed 200. Specifically, the dispensing device 100 comprises a dispensing assembly 1 and a plurality of visual detection assemblies 2, wherein the dispensing assembly 1 can dispense the product to be dispensed 200, the plurality of visual detection assemblies 2 are arranged around the outer periphery of the dispensing assembly 1 and the product to be dispensed 200, the visual detection assemblies 2 are arranged corresponding to the side edges of the product to be dispensed 200, and the detection range of each visual detection assembly 2 can cover the entire product to be dispensed 200. When the dispensing assembly 1 dispenses the side edges of the product to be dispensed 200, the visual detection assembly 2 corresponding to the side edge being dispensed is configured to plan and guide the dispensing path of the dispensing assembly 1 in real time, the remaining visual detection assemblies 2 are configured to detect the glue line quality of the dispensing assembly 1 in real time, and the dispensing assembly 1 dispenses according to the glue line quality feedback by the visual detection assembly 2. So that the dispensing device 100 not only can quickly plan the dispensing path and optimize the dispensing trajectory in real time, but also can dispense according to the feedback of the glue line quality and optimize the glue line quality.
