The cylinder 8 is opened to insert the sealing ring 1101 on the dispensing tube 10 into the sealing groove. The rubber sealing ring 1102 and the silicone sealing ring 1103 seal the connection between the sealing ring 1101 and the sealing groove, achieving the effect of dispensing different areas of glue to the LCD screen, which is suitable for different dispensing needs. A glue supply tube 12 is fixedly installed on one side of the support frame 2, and a valve is fixedly installed on the surface of the glue supply tube 12.

[0027] like Figure 2 As shown, the heating mechanism 4 includes a heating plate 401 and a temperature controller 402. The heating plate 401 is fixedly disposed inside the cavity, and the temperature controller 402 is fixedly installed on the surface of the glue container 3 and electrically connected to the heating plate 401.

[0028] The heating mechanism 4 is designed to heat the adhesive in the adhesive container 3.

[0029] like Figure 3 As shown, the stirring mechanism 7 includes a stirring rod 701 and a degumming plate 702. The stirring rod 701 is fixedly mounted on the output end of the A servo motor 6, and the degumming plate 702 is fixedly mounted on the surface of the stirring rod 701.

[0030] The stirring mechanism 7 is designed to stir the adhesive liquid, preventing it from solidifying and separating.

[0031] like Figure 5As shown, the switching mechanism 9 includes a B servo motor 901 and a switching frame 902. The B servo motor 901 is fixedly mounted on the output end of the cylinder 8, and the switching frame 902 is fixedly mounted on the output end of the B servo motor 901.

The sealing ring 1101 is fixedly disposed on the top of the dispensing tube 10, the rubber sealing ring 1102 is fixedly disposed on the top of the sealing ring 1101, and the silicone sealing ring 1103 is fixedly disposed on the top surface of the rubber sealing ring 1102. The tube wall of the dispensing tube 12 is provided with a sealing groove that matches the sealing ring 1101.

[0034] The sealing component 11 serves to seal the connection between the dispensing tube 10 and the dispensing tube 12.

[0035] like Figure 4 As shown, a glue pump 13 is fixedly installed on the top surface of the support frame 2. A glue extraction pipe 14 is provided through the input end of the glue pump 13. One end of the glue extraction pipe 14 is provided through the inside of the glue tank 3. The output end of the glue pump 13 is connected through the glue delivery pipe 12.

[0040] The working principle of this utility model is as follows: the drive motor 15 drives the display screen conveyor belt 16 to rotate, and transports the LCD display screen to the bottom of the support frame 2.

[0041] The dispensing liquid for the LCD screen is poured into the dispensing container 3. After the heating plate 401 is powered on, it heats the dispensing liquid. The temperature controller 402 controls the heating temperature. The servo motor A drives the stirring rod 701 to rotate, stirring the dispensing liquid to improve its fluidity and prevent it from solidifying and separating, which would affect the dispensing. At the same time, the dispensing plate 702 scrapes off the dispensing liquid adhering to the wall of the dispensing container 3 when it rotates, so as to avoid the dispensing liquid being difficult to clean after solidification and causing waste.

[0042] When dispensing different sizes of glue onto an LCD screen, an external power supply is connected, and the B servo motor 901 drives the switching frame 902 to rotate, switching the glue dispensing tube 10 of appropriate diameter to below the glue delivery tube 12. The cylinder 8 is opened to insert the sealing ring 1101 on the glue dispensing tube 10 into the sealing groove. The rubber sealing ring 1102 and the silicone sealing ring 1103 seal the connection between the sealing ring 1101 and the sealing groove, thus dispensing different areas of glue onto the LCD screen to meet different glue dispensing needs.
