[0033] Embodiment 2

[0034] With reference to Figure 1 、 Figure 2 、 Figure 3 and Figure 4 , this is a second embodiment of the utility model, which is based on the previous embodiment. The cleaning mechanism 2 comprises a filter plate 205 fixedly connected to the inner wall of the nozzle body 1. The outer surface of the filter plate 205 is rotatably connected with a cleaning frame 206. The outer surface of the cleaning frame 206 is rotatably connected to the inner wall of the nozzle body 1. The outer surface of the cleaning frame 206 is fixedly connected with a connecting shaft 203.

[0035] Specifically, the outer surface of the nozzle body 1 is fixedly connected with a fixed block 202. The outer surface of the fixed block 202 is attached with a sealing sleeve 204. The outer surface of the sealing sleeve 204 is threadedly connected with a bolt 201. The outer surface of the bolt 201 is threadedly connected to the outer surface of the fixed block 202.

The servo motor 304, the temperature sensor 301 and the resistance heating wire 306 are all connected with the control system of the visual glue filling machine. The temperature sensor 301 transmits the detected glue temperature signal to the control system. When the temperature is lower than the set value, the control system issues an instruction to start the resistance heating wire 306 to heat the glue.

When the glue enters the nozzle body 1, the spiral conveying paddle 305 continuously rotates to push the glue from the feeding end of the nozzle to the discharging end. This continuous and stable pushing action makes the glue always in a flowing state, avoids the risk of clogging the nozzle due to the condensation and precipitation of the glue in the nozzle for too long time, and reduces the risk of clogging the nozzle. In this process, the temperature sensor 301 detects the temperature of the glue in the nozzle body 1 in real time, if the glue temperature is too low, the resistance heating wire 306 will start to heat the glue, increase the flowability of the glue, and ensure that the glue can flow smoothly from the nozzle body 1, when it is necessary to clean the impurities on the filter plate 205, the sealing sleeve 204 can be disassembled from the fixed block 202 by rotating the bolt 201, so as to facilitate cleaning the filter plate 205.
